Abstract: ABSTRACT OF THE DISCLOSURE        The invention involves pulling the hide mechanically from beef carcasses, in a manner such as to avoid hide and carcass damage without resorting to electric stimulus, and without the need for trimming knife labor in removing the hide effectively and advantageously from the skull of the carcass.          The invention thus provides a method of removing the hide from a meat carcass including a head having the hide slitted lengthwise along the belly, the hide being partially detached from the carcass to provide side flaps disposed along opposite sides of the carcass, including flap portions resulting from peeling the hide from the forelegs, said method comprising the steps of:  suspending the carcass from the hind legs with the unskinned head and the skinned forelegs lowermost; gripping the side flaps at opposite sides of the carcass near the forelegs, and forcibly pulling the hide over and off the head while restraining the forelegs against movement in the direction of the hide pulling force.

Abstract: CLUSTERED LOGIC ARRAYS                         ABSTRACT This specification describes a programmable logic array (PLA) in which the readout table or OR array for the PLA is broken into two segments and the segments placed on opposite sides of the search table or AND array for the PLA.  The out-put lines for the AND array can then be split so that outputs on one segment of those lines are fed to the OR array on one side and outputs on the other portion of those lines are fed to the OR array on the opposite side.  Likewise the output lines in the OR arrays can be broken so that different func-tions can be fed out to opposite sides of the OR arrays.  It is also possible to break input lines in both the OR and AND arrays to isolate functions from one another.

Abstract: Abstract of the Disclosure In an assembly of fusion furnace and fusion head for applying heat to plastic pieces to be fused, the furnace being fired with gaseous fuel red through a conduit to a burner head in the furnace from a source of fuel, a tempera-ture sensing probe projects into the furnace.  The tempera-ture sensing probe is operatively connected to a gas flow control device in the conduit from the source to the burner.          The flow control device acts to throttle the gas flow, to maintain a predetermined variably selective temperature of the probe, from a high pressure, highrate of flow of gas to a low rate of flow of gas to the burner head.  A fusion head block has a well in it to receive the temperature sensing probe when the fusion head block is in a predetermined heat-receiving position with respect to the burner head, the well being spaced from the burner head.  The burner head is pro-vided with a wire screen to ensure the maintenance of a flame at a reduced flow rate of the gaseous fuel.

Abstract: ABSTRACT OF THE DISCLOSURE        In an optical video disc where the storage track is a succession of cavities or pits alternating with a like succession of lands, these elements ideally have a certain length, determined by the encoding method used.  Experience shows, however, that they may in practice suffer unintended length variations giving rise to duty factor error.  A com-pensating change is made to the duty factor of the signal developed in reading the disc in order to obviate spurious components attributable to duty factor error and otherwise the source of distortion in image reproduction.

Abstract: ABSTRACT OF THE DISCLOSURE            Improved electronic scale system for weighing, computing a value and printing a label showing the weight, price per unit weight and the computed value for each of a plurality of succes-sive articles.  An integrated circuit microcomputer is periodi-cally supplied with the article weight from a load cell scale and is supplied with the price per unit weight either from a manual keyboard or automatically from a commodity plate in a label printer.  After the system corrects for scale error, checks for scale no motion, compensates for any tare weight and checks various interlocks, the microcomputer computes an article value.          A no motion signal is generated by the microcomputer when a predetermined number of successive weight measurements deviate from one another by no more than a predetermined small frac-tional weight less than the least significant weight digit used by the microcomputer in computing an article value.  After the above operations are performed, the microcomputer causes a printer to print an article label bearing the corrected weight, the price per unit weight and the computed value.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to electrodeless discharges and, more particularly, to improving the conversion efficiency of electrical power to light by means of an electrodeless discharge.  In the common incandescent lamp, the light emitting filament evaporates and becomes weak with use, hence is easily fractured or dislodged from its supports.  More importantly, the efficiency of an incandescent lamp in converting electrical power to light is very low.  Fluorescent lamps are generally more efficient and durable than incandescent lamps, but they require both a ballast supply and a special fixture which must be installed before a lamp can be used.  Further, the electrodes are subject to disintegration over a period of time.  the present invention overcomes these deficiencies by providing an electrodeless discharge lamp having an inonizable medium comprising a particular gas composi-tion at a particular pressure within a sealed envelope.  Radio frequency electrical power is applied to an induction coil, the magnetic induction field of which is coupled to the medium.  for a particular radio frequency, the magnitude of the induction field is selected to maximize the light emitted by the discharge per watt of radio frequency power coupled thereto.  In one embodiment, a mixture of mercury vapor and argon is contained within an envelope having an open cylindrical cavity into which the coil fits; the portion of the interior surface of the envelope defining the cavity has a layer of an electrically insulative, ultraviolet reflective material, and the entire interior surface of the envelope has a phosphor layer.

One form of the locking system is in a sliding sleeve valve including a cam release shoulder to free a selector and locking key when the sleeve valve is moved between spaced longitudinal locations.  Another form of the locking system may be along a landing nipple and require that the well tool locked therein be disabled for release of the selector and locking tools.  The sleeve shifting device has means for opening and closing the sliding sleeve valve including keys having upwardly and downwardly facing stop shoulders and recess profiles which are compatible with the landing and locking recess profile of the sleeve valve or of a landing nipple.  The sleeve shifting device may be used also as a locking mandrel.  Selectivity is provided by variation in the landing and locking profiles and the key profiles.

Abstract: VERTICAL FLOAT SWITCH           ABSTRACT OF THE INVENTION:        A vertical float switch, suitable for use as a low water cut-off control or the like, having differential adjustment means is disclosed. The float switch includes a hollow housing forming a float chamber which communicates with a hot water boiler vessel by way of vertically spaced equalizing lines. A non-magnetic sealing tube extends vertically away from the housing and communicates with the float chamber of the housing. A float rod is slidably mounted within the housing by way of a generally cylindrical guiding collar. A float is mounted to the lower end of the rod for translating the rod in accordance with the level of the water within the float chamber. An armature of magnetic material is fixedly mounted to the other end of the rod for translation with the tube in accordance with the level of the water within the boiler. A switch frame is clamped at a predetermined point along the tube, and includes a bracket pivotally mounted thereon for translation toward and away from the tube. A permanent magnet and a switch, such as a mercury switch or a microswitch, are carried by the bracket. A spring is mounted between the point on the bracket, which is above the pivotal axis, and a point on the switch frame and functions to urge the permanent magnet away from the tube. The spring mounting point on the switch frame includes a slotted adjustable fastener for adjusting the length of the spring and, therefore, the spring force. Accordingly, the on-off differential of the switch is adjusted by adjusting the position of the slotted fastener. The cylindrical collar functions as a guide and maintains a given spaced-apart relationship between the float and the float chamber walls.
