Granted: 1991-10-01
Abstract: HEIDELBERG              A-499             17.07.1986 Bo/Str/1044k A B S T R A C T            The invention relates to an ink duct for offset or letterpress machines, with the ink-duct side parts being movable with respect to the duct roller and with respect to the ink duct.  The end face of the ink-duct side part is of form-fit design with respect to the surface of the duct roller and is in contact with the latter.  In addition, the side part is adapted to swivel about an axis extending parallel to the duct roller and is in contact with the end of the ductor knife.  The necessary contact pressure is produced by spring elements.  The aforementioned arrangement of the ink-duct side part permits the independent adaptation of the ink-duct side parts to different operating conditions and serves to simplify the assembling of the ink duct.

Title: Arithmetic coding encoder and decoder system
Inventor: LANGDON GLEN G JR
IPC: G06T9/00
Filed: 1987-08-07
Granted: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus and method for compressing and de-compressing bi-nary decision data by arithmetic coding and decoding wherein the estimated probability Qe of the less probable of the two decision events, or outcomes, adapts as decisions are suc-cessively encoded.  To  facilitate  coding computations,  an augend value A for the current number line interval is held to approximate one by renormalizing A whenever it becomes less than a prescribed minimum AMIN. When A is renormalized, the value of Qe is up-dated.  The renormalization of A and up-dating of Qe are preferably based on a single-bit test.          Also, each Qe value is preferably specified as a 12-bit value having the least significant bit set to 1 and having no more than four other bits set to 1. The number of Qe values in the 1/4 to 1/2 probability range is enhanced to improve coding efficiency.   A decision coding parameter of preferably six bits indicates the sense of the more probable symbol (MPS) in one bit and identifies a corresponding Qe value with the remaining five bits. In addition to probability adaptation, the present invention discloses an allocation of bits in a code stream register in which preferably two spacer bits are inserted between a next byte portion (which contains a byte of data en route to a buffer) and a fractional portion which may be involved in further computation. With the two spacer bits, any code greater than or equal to Hex 'CO' which fol-lows a Hex 'FF' byte is illegal for data and therefore pro-vides for an escape from the code stream. The two spacer bits also reduce the number of stuff bits inserted to account for carry or borrow propagation. Encoding and decoding can be performed interchangeably by hardware or software which fea-ture differing coding conventions.

Abstract: Abstract of the Disclosure A biological tissue stimulator (10) is disclosed having an adjustable high voltage power supply (14). The high voltage power supply (14) is coupled to a battery (12) producing a high voltage signal to be supplied to an output circuit (16) for supplying an electrical stimulation signal of a predetermined current amplitude. An electrode (18) is coupled to the electrical stimulation pulse and is adapted to be coupled to the biological tissue to deliver the electrical stimulation signal to the biological tissue. An adjustment mechanism (26) is coupled to the output stage (16) and to the adjustable high voltage power supply (14) for comparing the amplitude of the high voltage signal to the amplitude of the voltage drop across the biological load and adjusting the amplitude of the high voltage signal dependent upon the result of that comparison. The adjustment mechanism (26) adjusts the amplitude of the high voltage signal to minimize the difference in the amplitude between the high voltage signal and the voltage drop across the biological load thereby maximizing the energy efficiency of the biological tissue stimulator (10).

Title: Hot gas defrost system for refrigeration systems and apparatus therefor
Inventor: GREGORY CHARLES
IPC: F25B47/00
Filed: 1988-07-11
Granted: 1992-05-19
Abstract: ABSTRACT          This invention provides a full flow vaporizer for use in a refrigeration system employing hot gas from the compressor to periodically defrost the cooling coil, or coils where multiple coils are employed.  The vaporizer usually consists of three concentric circular cross-section tubes, the inner tube receiving the fluid from the coil and being provided in its wall with a plurality of fine bores directing the fluid forcefully radially outwards against the inner wall of the middle tube, which is heated by the hot gas.  The flow capacities of the passages and the bores are chosen to be in a specific range of flow capacities relative to one another, so that when not in use the vaporizer has no appreciable effect on the remainder of the system.  An orifice or restriction is provided at the outlet for the hot gas from the third annular passage through which the hot gas passes and heat the tube wall to vaporise any liquid refrigerant, and increases the back-pressure applied to the compressor, rendering the device self-balancing to prevent compressor motor overload.  The vaporizer may be of other configurations, for example three rectangular chambers having two walls in common (Figs 5-7).   Each restrictor may be provided downstream with a respective expansion chamber to re-evaporate any liquid that passes through the restrictor and maintain gas flow velocity.  In a multiple evaporator system each evaporator may be provided with a respective adjustable restrictor to permit equalisation of the pressure drops in the individual hot gas lines and consequent equalisation of the respective defrost requirements.

Abstract: ELECTRONIC ARTICLE SURVEILLANCE SYSTEM          UTILIZING SYNCHRONOUS INTEGRATION               Abstract of the Disclosure An electronic article surveillance system employs a resonant tag attached to an article being protected.  An interrogation transmitter whose trans-mission frequency is periodically swept through the resonant frequency of the tag is positioned near an exit of the protected area.  The resonant tag is periodically energized by the transmitter as the trans-mitter frequency passes through the resonant frequency of the tag to cause the tag to emit a periodic tag signal at the sweep rate of the transmitter.  The tag signal is received by a receiver that generates an alarm upon the detection of a tag signal.  The receiver employs synchronous integration in the form of a dual channel synchronous video integrator to independently process positive and negative pulses of the tag signal in order to differentiate the tag signal from ex-traneous signals and noise.
