Apparatus and system for controllably removing liquid from tofu with no or minimal cracking or deforming. An interior box contains tofu. Interior box is insertable and removable from exterior box. Interior box includes drain(s) for liquid removed from tofu, and resilient spacers on bottom to create space between bottoms of interior and exterior boxes for containing drained liquid and for cushioning tofu when pressed. A cover releasably attaches to top of nested boxes. Telescoping extender extends through cover into interior box. Extender is attached at one end to inside cover and attached at other end through a spring-loaded cap to a press plate. Extender has interior tier cylinder nested within exterior tier cylinder. Extender progressively telescopes interior cylinder out of exterior cylinder, and then telescopes exterior tier cylinder to extend press plate further into interior box to press tofu to release liquid. Spring-loaded cap on extender cushions pressure on tofu.

A device and method of forming smokable materials are disclosed. The device may include a puck, which may be configured to at least partially pass through a channel defined by a die from one end of the die. The die and the puck are configured such that smokable material may be placed within the die from that end and compressed by the puck against a substantially rigid surface proximal to the other end of the die. The puck may be pushed through the channel in the die using a feature that provides mechanical advantage. The puck and die may also be attached to or may be part of a press, such as a t-handle press. A spacer may also be included to maintain a minimum height of the compressed smokable material. The device is configured such that the compressed smokable material may be inserted into the oven of a vaporizer.

Provided is a device for improving perovskite film formation uniformity, including a grinder and a sheeter, wherein the grinder grinds a perovskite precursor into a powder, the sheeter presses the ground precursor powder into a precursor sheet, the sheeter includes a mold for pressing the precursor powder and a heating device, and the heating device heats a lower mold. A method of using the above device for improving perovskite film formation uniformity, and a method of preparing a perovskite solar cell are also provided. The precursor sheet prepared herein not only solves the problems of uneven particle size and uneven spreading at the bottom of the evaporation source or incomplete coverage, but also prevents splashing during vacuuming and aeration, and meanwhile, since the precursor powder is compacted, it is more conducive to the uniform conduction of heat during the heating and evaporation process, thereby improving the heat energy use efficiency.

A soap bar forming apparatus and method for forming a soap bar by compression welding a plurality of soap slabs is configured to mechanically weld a plurality of soap slabs into a single soap bar of a usable size. The soap slabs are placed on the open top chamber of the lower casing in a flat stacked position. The upper casing is then placed over the lower casing and then both the casings are tied in place by the Velcro straps. The upper casing detachably couples to the lower casing and a pair of detachable straps fasten the casings together. A drive member presses the soap slabs together, and comprises a rotatable compression screw terminating at a compression plate, and an E-Ring that fastens the compression screw and compression plate together, and allows the compression screw to rotate while the compression plate moves up and down without twisting. The rotatable compression screw rotatably passes through the threaded drive hole in the upper casing, forcibly urging the compression plate onto the soap slabs to compress the soap slabs into a single large soap bar.

This disclosure details a surgical system and method for changing one or more dimensions of harvested tissue, such an autograft, which is harvested from one location in a patient's body and used for a surgical repair or reconstruction procedure in another location in the patient's body. An example surgical system includes a first press component defining a cavity configured to receive harvested tissue, and a second press component including a projection insertable into the cavity. Further, at least one of the first and second press components are made of a transparent or semi-transparent material such that when harvested tissue is in the cavity and when the projection is inserted into the cavity, the harvested tissue is visible through at least one of the first and second press components.
