Abstract: DUAL ROTATING MECHANICAL LOCK     Abstract of the Disclosure A mechanical lock of the type in which axial translational movement of a rod is prevented by a coil spring which encircles the rod and grips it and being readily released by application of a relatively small force through a relatively short stroke, thereby permitting the mechanical lock to be controlled by a pushbutton con-trol.  Rotating bushings adjacent the ends of the springs have beveled faces which cause the locking turns at the ends of the spring to become cocked on the rod to provide a true locking action.  The device is unlocked by rotation of the rotating bushings, which unwind the locking turns of the spring, thereby releasing the grip of the spring on the rod.          The rotating bushings are rotated in opposite directions by actuating levers which extend outside of the housing of the device.  The actuating levers are provided with rollers and are located at the same station along the axis of the rod.  A symmetrical wedge-shaped cam is mounted so that it can be drawn axially between the rollers, forcing them apart circumferentially and thereby rotating the actuating lever about the axis of the rod.  The wedge-shaped cam is drawn in an axial direcion by a cable which is connected to the pushbutton control.  The structure of the device simplifies its assembly, thereby reducing the production cost.

Abstract: A hydraulic system comprising a full flow supercharged variable displacement pump and a fixed displacement charge pump adapted to be driven by the same prime mover as the variable displacement pump for supplying fluid to the variable displacement pump. An orifice is provided in the supply line to the variable displacement pump, a circuit is provided from a point downstream of the orifice to tank pressure, and a feedback valve is provided in series with the circuit. The feedback valve comprises a pair of mutually and oppositely adjustable flow restrictions in series with said circuit. The restrictions are connected to the displacement varying means to vary them equally and oppositely in proportion to the movements of the displacement varying means. A speed sensing control valve is responsive to the pressure level between the two restrictions and the pressure level upstream of the orifice and is connected to the outlet of the variable displacement pump and operable to operate the displacement varying means to reduce the displacement of the pump then the pressure differential between the pressure at the outlet of the feedback means and the pressure upstream of the orifice falls below a predetermined value.

Abstract: ABSTRACT OF THE DISCLOSURE          An electonic security device includes a memory and a card reader which reads a combination code and calculation data from a key card.  An electronic circuit compares the content of the memory with the combination code and enables the lock device if a match is found.  If the key card is a new one the circuit calculates a new combination code by applying the calculation data to the memory content and, if this new combination code mat-ches that on the key card the memory is loaded with the new combination code.

Abstract: ABSTRACT     A door-operating mechanism for a rotatable drum which has a mouth to be closed by a door includes a moveable arm hingedly mounted with anchoring means on the side of the frame of the drum, and clamp means for connection with a stub shaft extending from the door.  When the door is closed on the mouth of the drum, the clamp means is disengaged from the stub shaft so that the door is secured, under vacuum pressure within the drum, as an integral part of the rotating drum.  Force is thus O avoided on the hinged, moveable arm, and stub shaft of the door and  door-operating mechanism.  The clamp means includes jaws which are activated to release the door after a predetermined vacuum pressure exists within the drum.      The drum is part of processing apparatus in which different products can be processed.  Such processing includes the kneading of food pieces and the blending of food constituents.  The kneading can be applied to massaging or tumbling meat chunks.

Abstract: TEMPERATURE COMPENSATED GAUGE  FOR PRESSURIZED GAS SUCH AS NATURAL GAS FUEL FOR VEHICLES                   Abstract of the Disclosure A temperature compensated gauge for measuring and indicating the quantity of a gas within a pressurized system is provided, which, in addition to achieving a degree of accuracy appropriate for most practical applications, is characterized by qualities of simplicity, reliability and ruggedness.          The last-mentioned qualities render the improved gauge especially suited for use in possibly adverse environments, such as for monitoring the remaining supply of compressed natural gas or analogous fuels on board a moving vehicle.  The improved gauge is predominantly electrical in nature and employs a limited number of commonly available and relatively inexpensive components, which enhances its practicality for wide spread utilization in virtually any application where measurements of the pressure of any confined gas must be compensated for the effects of temperature in order to provide an accurate indication of the quantity of gas in the system under variable ambient temperature conditions.

Abstract: ABSTRACT          Vacuum pneumatic conveying apparatus and method are utilized to transfer food products, such as fish, from a boat to a processing factory directly or via a tender vessel.  Fish products such as salmon, are withdrawn from a fishing boat through an intake nozzle of a pneumatic vacuum system and entrained in an air flow, upwardly through inlet or receiving conduits of a vacuum pneumatic, conveying system and on through a product separator of an in line assembly of an upper product separator and a lower liquid separator.  Salmon continue on flying out of the product separator and commence their downwardly momentum and gravity induced travel through discharge conduits, encompassing essentially non flowing air maintained under continuing vacuum.  They reach a lower exit volume and collect temporarily in an active changing group to intermittently force open, against barometric pressure, an otherwise self sealing, flexible discharge sleeve, to be discharged without injury and conveyed elsewhere in a fish processing factory.  The air flow under vacuum in which the salmon are entrained eventually flows through an enlarged downwardly directed internal conduit within the product separator, to escape radially through a longitudinally grilled exit, and the salmon continue on via their momentum downwardly for discharge.  The escaping air flow expands and reverses, separating its water and flows through a rotary positive displacement blower into the atmosphere.

Abstract: CHIP THICKNESS SEPARATOR                  ABSTRACT OF DISCLOSURE         Materials such as wood chips or other materials are classified by thickness by feeding same through a chip inlet onto a rotating disc adjacent the axis of rotation of the disc.  The disc cooperates with a housing to define a tapering passage terminating in a narrow, restricted outlet adjacent the periphery of the disc.  Orienting bars project from the disc and extend radially from the axis of rotation to beyond the chip inlet.  A frusto conical chip orienting surface extends from the radial outward extrem-ities of the orienting bars toward the outlet in a posi-tion traversing the path of material leaving the orienting bars.  In a particular case, an oversized outlet is pro-vided, positioned trailing the orienting bars in the direction of rotation an unobstructed trajectory of material leaving the orienting bars.  In another case, the oversized outlets breaker bars that cooperate with co-operating breaker bars on the housing to shear positions of the material away.  In still another case, the cooperating breaker bars are replaced by breaking bars on the disc and cutting blades on a housing to shear the wood chips and reduce their thickness.
