Abstract: VENDING CONTROL SYSTEM                   ABSTRACT OF THE DISCLOSURE       The vending control system has first and second motor-and dispensing- assemblies, each assembly including a motor for driving a load and dispensing a product, a motor cam switch connected to the motor, a load cam switch connected to the motor, a motor cam drivingly connected to the motor and operatively actuating the motor cam switch, a load cam operatively actuating the load cam switch, and a torque-limiting clutch interconnecting the cams for driving the load cam and for permitting relative rotational movement of the cams at predetermined torque value.          The assemblies are connected in parallel, with the motor and load cam switch of each assembly connected across the power sources.  The motor cam switch of the first assembly is connected to the power source and to the motor cam switch of the second assembly.  An actuator selectively energizes the motor of one of the assemblies through the associated load cam switch so that the motor cam of the selectively energized motor actuates its associated motor cam switch to operatively connect the motor to the power source, and so that the load cam of the selectively energized motor subsequently actuates its associated load cam switch to operatively disconnect the motor from the power source as the cams are drivingly rotated by the motor.  The motor cam of the selectively energized motor actuates its motor cam switch to operatively disconnect the motor from the power source, and operatively connects the motor cam switch of the other assembly to the power source as the motor cam rotates relative to its associated load cam when the predetermined torque value of the clutch is exceeded upon jamming of the load cam.

Abstract: ABSTRACT OF THE DISCLOSURE:     A heating device for installation on the roof of a struc-ture to permit water to flow off the structure from behind a blockage of ice.  An elongate, hollow tubular member defines a chamber in which is situated a point heat source.  A jacket of insulative material surrounds the tubular member to retard heat loss.  One side of the jacket faces the roof and has a channel open to the tubular member such that heat transfer from the tubular member occurs primarily through the channel. When the device is installed on a roof, heat radiated through the channel forms heated passageways through the ice blockage for escape of water.

Abstract: ABSTRACT OF THE DISCLOSURE:           The process basically consists of the removal of the impurities contained in the titanium minerals, in which it appears in the form of oxides, which cannot be eliminated by the conventional hydro-metallurgical processes.  The conditioning of the mineral by pire-metallurgical treatment followed by mag-netic separation, removes a part of the magnetic impurities at the same time that it exposes those impurities to the action of the leaching acids and thus makes it possible for them to be removed easily.  The alkaline treatment following the acid leach-ing permits elimination of the phosphores contained as a harmful impurity, and makes it possible to secure a product within the specifications of the consumer market for use as a raw material mainly for the obtaining of pigments and metallic titanium, which are the main forms in which titanium ores enter into consumption.

Abstract: DUAL INJECTOR, FLOATING GATE MOS ELECTRICALLY ALTERABLE, NON-VOLATILE SEMICONDUCTOR MEMORY DEVICE     ABSTRACT OF THE DISCLOSURE     A dual injector, floating-gate MOS non-volatile semiconductor memory device (DIFMOS) has been fabricated, using process specifications and design rules of the same general character previously developed for single-level metal gate CMOS devices.  An electron injector junction (p+/n) is avalanched to "write" a charge on the floating gate, and a hole injector junction (n+/p-) is avalanched to "erase" the charge.  An MOS sensing transistor, whose gate is an extension of the floating gate, "reads" the presense or absence  of charge on the floating gate.  In a preferred embodiment, the hole injection means includes an MOS "bootstrap" capacitor for coupling a voltage bias to the floating gate.

Abstract: A B S T R A C T         This invention consists of a device which is inserted into the top of a fireplace for the purpose of increasing its heating capacity.  It consists of a "U" shaped tube of rec-tangular cross-section, having a flat rear section with diverging arms which bend outwardly at their ends.  To the end of one arm is attached a casing containing a blower or fan which blows cold or room temperature air into said tube, wherein it is heated, and passed out through the other arm which is equipped at its end with a louver.  The blower and louver are inter-changeable between the said arms. The U-shaped tube is provided with a plurality of diamond shaped and round ducts passing through it, so that the combustion products such as hot gases, flame, and smoke pass through their ducts towards the chimney, thus heating the air within the U-shaped tube, surrounding the said ducts.  The tube is provided with means for its attachment to the fireplace, and with permanent and removable baffles for directing the hot combustion products in the fireplace towards said tube.

Abstract: LIMITED SLIP DIFFERENTIAL     A B S T R A C T         A limited slip differential is adapted for use in self-propelled wheeled vehicles requiring maximum available tractive effort.  The differential utilizes a gearless design for differentiation and compact gearing therewith for reliability and increased limited slippage characteristics.  The preferred differential embodiment comprises a housing having a slide block mounted therein for relative reciprocation in a first plane perpendicular to a longitudinal axis of the differential.          A pair of first gear members, each having teeth formed internally thereon, are disposed on either side of the slide block and are keyed thereto for relative reciprocation in a second plane and longitudinal axis. A pair of second gear members, each adapted for securance to a drive axle and having teeth formed externally thereon, are rotatably mounted in the housing.   Each second gear meshes with a respective first gear and has a lesser number of teeth to form a cycloidal gear set whereby each first gear will orbit in a circular path about the longitudinal axis of the differential, allowing its meshing second gear to rotate in a direction opposite thereto.  A cross-over control means is pivotally interconnected between the slide block and first gears to assure that the drive axles will rotate in opposite directions during all phases of differentiation.
