In one embodiment, a pair of concentric wheels are utilized with hands arranged on an outer, stationary wheel and individual card indicia arranged on an inner rotatable wheel. The rotatable wheel is divided into four concentric annular areas, which areas are subdivided into alternating 52 space and 13 space configurations. The stationary wheel is subdivided into 13 spaces each of which has indicia therein indicative of a class of playing card hands or an instruction. A second embodiment utilizes a single rotatable wheel with fifty-two segments representing the fifty-two cards of the standard playing card deck in combination with a horizontal play surface which includes fifty-two spaces arranged in rows according to suit and columns according to denomination.

Abstract: A system for identifying emergency exits in a building includes a strobe light which is tethered at an elevated location with respect to the floor of the building. The strobe light is normally held at the elevated position by an electromagnet, which electromagnet is kept energized as long as a smoke detector connected thereto does not sense a dangerous level of smoke. As soon as the smoke detector detects smoke above a certain threshold level, the electromagnet is deenergized and the strobe light drops to a position suspended just above the floor. The strobe light includes its own battery source which is connected to the strobe light by a switch which closes when the strobe light is dropped. An electric motor is provided to rewind the tether when the smoke detector no longer indicates an emergency situation. By tethering the strobe light, the light can be dropped beneath the smoke level in the building, allowing people crawling along the floor to determine the location of emergency exits.

Abstract: A rolling wobble press includes a planar surface which is perpendicular to a first axis and a cone which rolls on the planar surface as the cone revolves around the first axis. The axis around which the cone rotates as it rolls intersects the first axis at the same point that the first axis intersects the planar surface so that under ordinary circumstances, there is no slippage between the cone and the planar surface. The cone is driven by a drive shaft which is coaxial with the first axis. The drive shaft is connected to the cone via a crank having an arm oriented obliquely thereto in which arm the cone is rotatably journaled.In accordance with one embodiment of the press, the press is used to drive a plurality of punches in a riveting machine.

Abstract: In order to secure an emergency exit door against unauthorized opening from the inside, a retrofit delay mechanism is attached to the door frame. The delay mechanism includes a retractable bolt which projects behind a strike mounted on the door. A piston is attached to the bolt and a hydraulic circuit is connected to the piston. The hydraulic circuit includes a throttle and a normally open valve. The normally open valve is held closed by a solenoid. Upon attempting to open the door, fluid in the hydraulic circuit is throttled slowing down retraction of the bolt and delaying opening of the door. The solenoid which releases the normally open valve is connected to a timing circuit which de-energizes the solenoid after a predetermined time interval thus providing a redundant delay arrangement. Smoke detectors, fire pull-boxes and a remote reset switch are also connected to the solenoid via a dropout relay.

Abstract: Opening of a door, such as an emergency exit door, is delayed by a door check, the operation of which has been reversed to delay opening of the door instead of delaying closing of the door. The delay is accomplished by a circuit which includes a normally open valve held closed by a solenoid. When the solenoid is de-energized, the circuit is opened allowing the reversed door check to operate so that the door can be opened. The solenoid is controlled by an electrical timing circuit which is started by a switch connected to a door operator such as a push bar.

Abstract: Apparatus for slaughtering animals in accordance with hallal or kosher provisions includes a table with a concave top surface having a drain therein and reeled straps for securing an animal. In one embodiment, the table is motor driven to tilt about one axis in order to secure the animal thereto and about another axis to slide the animal onto a conveyor belt after the animal has been slaughtered.In another embodiment, the table is equipped with folding legs so that it can be used on ceremonial occasions.

Abstract: A container for plants is rotated as water is evaporated and respirated therefrom due to the interaction between a compression spring and linear-to-rotary motion mechanism. The compression spring is disposed between the container and a stop on a support shaft suspended from above wherein the support shaft has a spiral portion thereon and the container has a slot for receiving the spiral portion. As water evaporates, weight on the compression spring is reduced and the container rises upwardly on the shaft in relation to the stop on the shaft. As the container rises, it rotates slowly. In an alternative embodiment, the shaft is rigidly fixed to a base upon which the container rests and the container includes a soil containing pot which may move relative to the base. The compression spring is disposed between a stop on the shaft and the soil containing pot to bias the pot upwardly when there is no water therein so as to raise and rotate the pot with the linear-to-rotary motion mechanism as the water evaporates.
