Abstract: A B S T R A C T                    Processing of gelatin A liquid melt comprising gelatin and water, optionally together with a polyhdric alcohol plasticizer therefor, is prepared by passing a mixture of solid gelatin and water, optionally with plasticizer, through an elongate tube whilst subjecting the mixture to the action of a high frequency alternating electric field, generated for example from a pair of electrodes mounted opposite each other outside the tube, to heat the mixture and convert it into a liquid melt. The elongate tube may be heated, e.g. by passing hot air around it, to prevent condensation of water vapour and the melting operation is suitably carried out under reduced pressure.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for making the supply of a material liquid and relief of pressure of a reaction product liquid in a high-pressure liquefaction reaction such as direct liquefaction of coal.  The apparatus includes at least one cylinder having two working chambers separated by a movable float, one of which is adapted to receive the material liquid while the other is adapted to be charged with the high-pressure product liquid.  A gas discharging pipe having a valve is connected to the side of the cylinder to which the high-pressure product slurry is to be charged.  For delivering the product slurry from the cylinder to the outside of the system, the pressure in the cylinder is beforehand relieved and the gases separated from the product slurry are discharged through the valve of the gas discharging pipe.  Thereafter, the product slurry filling the cylinder is delivered to the outside by a low pressure of the material slurry supplied to the other side of the cylinder.

Abstract: A B S T R A C T         METHOD AND APPARATUS FOR  IDENTIFYING WEAK SANDS      A method and apparatus for obtaining improved measurements of shear waves in low-velocity loose formations surrounding a bore-hole. The method comprises forming an interface between the bore-hole wall and a solid homogeneous material having a lower velocity than the formation. The geometry and velocity of the homogeneous material provide enhancement of the shear waves at the interface and thereby minimize the effect of interference from undesired compressional waves. Further improvement is obtained by using shear waves whose particles move perpendicular to the travel of the wave, parallel to the plane of the waves and perpendicular to the surface of the material. These are commonly referred to as SV shear waves.

Abstract: TITLE                ANALOG VOICE PRIVACY DEVICE FOR A                  SECURE COMMUNICATIONS SYSTEM        INVENTOR                           Brian Bryden ABSTRACT OF THE DISCLOSURE         The voice privacy device divides the voice waveform into equal segments and transmits the segments in an unnatural order.  In order to synchronize the terminals and unscramble the transmitted segments, the transmitter also sends a binary random sequence which it has generated in a register and which is duplicated in the receivers once initiated by the received sequence.  A day code determines the ports of the register that are to be connected to a key generator which generates key numbers for controlling the order in which segments are to be transmitted.  Synchronization of the receivers can occur at any point in the transmission, allowing the voice privacy device to be used under adverse conditions on mobile radio systems, as well as the dial-up telephone network.

Abstract: Applicant:    Stewart Ferguson Title:        Roof Or Sidewall Construction ABSTRACT                Generally rectangular wood shake covering elements lad up in overlapping courses are spaced apart transversely of their lengths by sawn wood shingle filler elements. Preferably the major portion of the overlapped portion of each course is formed by the tips of the sawn shingle filler elements, whereas the major portion of the exposed portion of each course is formed by the wood shake covering elements. One of such elements can be notched providing a transversely extend-ing shoulder dividing such elements into tip and butt portions of unequal width. In application, the shoulder tightly abuts the adjacent element. The covering and filler elements can be used to construct a roofing panel which includes a sawn shingle underlayer beneath each course and waterproof paper which underlies at least the major portion of the shingle underlayer but which is secured to the roofing panel by having one end portion interposed between the underlayer and the covering or filler element at one end of the panel. The covering elements can have registered kerf lines to align the successive courses of panels.

Abstract: DYNAMIC STACK DATA COMPRESSION AND          DECOMPRESSION SYSTEM     Abstract A system for encoding images by assigning variable-length code words to fixed positions in a dynamic stack.  Each position in the dynamic stack is occupied by a representation of an encodable image feature, such as a run-length or a vertical correlation.  These codes are arranged in order of their respective frequencies of occurrence.  The order in which these features are stacked is varied dynamically by the system, in accordance with their respective frequencies of occurrence and a predeter-mined scheme.  Thus, the system can adapt to different types of documents being scanned, or to changes of scanning resolution.  A relationship exists between the code words and the stack positions, which are not permanently assigned to specific image features.     This arrangement ensures that the lengths of code words will be inversely related to their frequencies of occurrence under all conditions.

Title: Television receiver saturating core regulated power supply with permanent magnet biasing
Inventor: WILLIS DONALD H
IPC: G05F3/06
Filed: 1982-05-25
Granted: 1985-07-02
Abstract: ABSTRACT OF THE DISCLOSURE A saturating core power supply for a television receiver includes a saturable reactor having a magnetizable core and a winding located thereon.  Exciting current for the saturable reactor is developed from a source of unregulated input voltage.  A magnetic flux is generated in the magnetizable core that links the reactor winding to develop an alternating polarity output voltage.  A capacitor develops a circulating current that generates a magnetizing force in a core section associated with the reactor winding. A permanent magnet biases the core to produce a second magnetizing force in the associated core section.  The resultant of the two magnetizing forces develops a magnetic flux that substantially saturates the magnetizable material of the associated core section during each cycle of the alternating polarity output voltage to regulate the output voltage.  The permanent magnet biasing provides temperature stability of the output voltage because the tendency of the output voltage to vary with temperature variations in the magnetizable material of the associated core section is substantially offset by the accompanying temperature variations of the biasing strength of the permanent magnet. A high voltage generator of the television receiver is responsive to the regulated alternating polarity output voltage to produce a temperature stable, regulated ultor voltage at a picture tube ultor terminal.
