Abstract: The customer terminal in a pneumatic drive-up banking arrangement is provided with an inner chamber into which carriers arrive. The usual valve in the receive tube is replaced with a hinged door at the front of the inner chamber which the weight of the carrier opens, the carrier then rolling down a ramp, formed in part by the door, over the funneled mouth of the send tube to a ledge along the front of the terminal from which it can be picked up by a customer. The teller can independently return the carrier from the ledge by means of a solenoid actuated lever which flips the carrier into the send tube mouth.

Abstract: An after-hours depository entrance of the drawer type employs an inclined passageway down through the drawer to receive a deposit. As the drawer is opened the passageway is "intercepted" by means in the drawer to detect any object trapped in the passageway before the drawer is fully open to receive a new deposit. As the drawer is closed, the new deposit is carried rearwardly in the passageway and finally, when the drawer is fully closed, it drops out through the bottom of the drawer into the vault. Two versions of the invention are disclosed, one for envelope deposits in which, as the drawer is opened, any envelope trapped therein is in effect destroyed or the drawer jammed against further opening by the interceptor means. The other version is for bag deposits in which, as the drawer is opened and if there is a bag trapped in it, the interceptor means likewise jams the drawer against further opening. In both versions the action of the interceptor means also frustrates any fishing attempts.

Abstract: A method of polishing material for lapidary and like purposes, the material and abrasive being tumbled in a vibrated container which alternately compacts the material against a wall of the container and then separates it in order to reduce the time required for polishing. Apparatus for carrying out the method vibrates the container of the material and abrasive so that a portion of its orbit is about a theoretical center which is above and to one side of the center of gravity of its mass.

Abstract: A demand type governor for gaseous fuel internal combustion engines, various kinds of breathing and heating apparatus and similar applications features a diaphragm controlled inlet valve having two different rates of opening movement for a given rate of movement of the diaphragm producing a relatively small amount of valve movement in relation to diaphragm movement for instances of lower demands and a relatively larger amount of valve movement in relation to diaphragm movement for instances of higher demands, all by means of a lever-fulcrum arrangement having a higher mechanical advantage in the first instances and a lower mechanical advantage in the second instances. Other features of the governor help assure its uniform, relatively frictionless operation, and its ease and economy of manufacture.

Abstract: A composite frame for a cone crusher and the like is fabricated from a number of separate frame members which are cut or rolled from plate material and secured by welds. A particular feature of the frame is the manner of connecting the crusher main shaft housing to the outer bowl supporting structure.

Abstract: A power driven ice dispenser in a freezer-refrigerator or the like discharges ice down a chute through the front of the unit. The chute is closed by a spring-loaded door opened by a lever. When the lever is released, an inertia motor delays closing of the door until the chute is emptied of ice.

Abstract: A programmer clock for use with alarm systems in banking and like institutions employs a diode matrix, day and hour stepper switches and a direct current motor driven clock, the positions and controls of all of which are mounted and visible on a single control panel. The condition of the alarm system and the program can be determined at a glance and the program itself can be readily and accurately altered at any time by authorized persons.

Abstract: A plier-type ratchet wrench of simple, economical and robust construction employs a single rigid thrust rod or bar to operate the ratchet drive and a single extensible helical spring which both biases the operating handle to its normal position and keeps the thrust rod and a pawl engaged with the ratchet.

Abstract: A roll crusher incorporates gas hydraulic springs to maintain the desired spacing between the crushing rolls and to provide overload protection. Featured are separate hydraulic means for backing off and then reapplying the hydraulic springs by altering their overall lengths so that roll spacing can be readily adjusted.

Abstract: The hooked ends of the springs or like members by which the bed of a trampoline or similar apparatus is suspended from its frame are equipped with protective sleeves of flexible material. The sleeves are split at their outer ends to form two flaps, one of which covers the exposed ends of the hooks to prevent injury to a performer inadvertently striking them, while the two flaps together are foldable back onto the sleeve to assist hooking and unhooking of the springs to and from the bed and the frame.

Abstract: An oral appliance for persons who have suffered facial burns to prevent shrinkage of the tissues around the mouth and lips during the healing process (microstomia). The appliance is adjustable to fit the patient's mouth and can be enlarged to progressively widen the opening of the mouth if shrinkage has already occurred. It may be employed to prevent shrinkage of the mouth and the lips by other causes (scleroderma, etc.).

Abstract: The cradle selector controls of a motorized rotary-type file comprise a row f simple, momentary-type pushbutton switches located in a small housing mounted so as to slide along the rear edge of the operator's shelf. The control housing is connected to the file where all other controls are located by an electrical cable, whereby the selector controls can be readily moved back and forth with the operator.
