Abstract: ABSTRACT OF THE DISCLOSURE           A thermostat for a stove is disclosed.  The thermal control unit is contained in a housing which has an aperture formed therein and includes a thermal control unit for de-tecting changes in the temperature of the stove.  A flap is secured to the housing and is rotatable across the aperture so as to cover the aperture to any desired degree.  The ther-mal control unit controls the position of the flap to control the effective area of the aperture, thereby to control the amount of air supplied to the stove.  The thermal control unit, the flap and the aperture cooperate to ensure that the effective area of the aperture changes by an amount approxi-mately proportional to the square of the magnitude of any change in the stove temperature detected by the thermal con-trol unit.  The thermal control unit may preferably comprise a bimetallic coil or a liquid expansion thermometer.  At least one edge of the flap, or at least one edge of the aper-ture, or at least one edge of each is curved in such a manner as to produce the desired change in area, in cooperation with the thermal control unit, responsive to stove temperature changes.

Abstract: IMPROVED VANE CONTROL FOR A VANE MOTOR          ABSTRACT OF THE DISCLOSURE:  A vane motor which uses two-lip vanes has a fluid restrictor in a fluid passage which connects the inner and outer ends of each vane.   High pres-sure fluid is supplied to the inner end of each vane as it traverses the transfer and sealing zone.   This fluid flows through the fluid passage to the outer end of the vane to pressure balance the vane.   In the event the outer end of a vane is separated from the cam ring the high pressure fluid at the outer end of the vane flows to the low pressure area and a pressure drop is created across the restrictor which results in a force which biases the vane towards the cam ring.

Abstract: ABSTRACT:               "IMPROVED WIRE DRAWING DIE AND    METHOD OF MAKING THE SAME"    A wire drawing die and method of making the same is provided in which an irregular-shaped metal blank having a cylindrical core formed of a synthetic, hard, wear-resistant material is adhered to a circular metal plate having a central opening therein, the core of the blank being centered with respect to the opening in the plate.          A metal die casing is provided having a cylindrical cavity therein, the cavity being proportioned to accom-modate the plate with a close fit.  A first disc of brazing material is placed on the cavity bottom and the metal plate with the blank thereon is placed on the brazing material disc.  A layer of metal powder is deposited in the cavity covering the metal plate and the blank.  Another disc of brazing material is placed on the metal powder layer.  A cylindrical metal plug is provided having an outside diameter proportioned to have a close fit with the casing cavity, the plug having a cavity formed in one end proportioned to accommodate the blank.  The plug is inserted in the casing cavity and pressure is applied to the plug to compress the metal powder.  Simultaneously, the plug and casing are heated to produce partial melting of the metal powder and complete melting of the brazing discs to form a body of consoli-dated metal encapsulating the die blank.  The casing and plug are then cooled under pressure to solidify the metal body thereby to secure the plate, die blank and plug in the casing cavity.  Countersunk openings are formed in the casing and the plug extending to the die core, and a die opening is drilled through the core communicating between the countersunk openings.

Title: Coin-operated latch mechanism
Inventor: VOEGELI RONALD C
IPC: G07F17/14
Filed: 1981-12-11
Granted: 1984-07-17
Abstract: ABSTRACT OF THE DISCLOSURE         A coin-operated latch mechanism includes a unitary frame member constructed of a single piece of material having a shape generally similar to that of an I-beam, to thereby reduce the number of parts required to construct the mechanism and simplify manufacturing operations.  The unitary frame construction also provides significant advantages with respect to durability and resistance to corrosion.  A pair of pivotal channel members that engage the frame to form coin chutes also engage one another by means of meshed teeth, so that pivotal motion imparted to one channel member will result in equal and opposite motion of the other channel member to thereby pivot the channel members away from the frame and open the coin chutes to enable trapped coins to be released.
