Title: Colour of polymers
Inventor: ZBORIL VACLAV G

Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE           A polymerization process, especially a solution polymerization process, for the preparation of high molecular weight polymers of alpha-olefins less susceptible to yellowness is disclosed.  The process comprises feeding monomer(s), coordination catalyst and optionally inert hydrocarbon solvent to a reactor, polymerizing the monomers at a temperature of up to 320°C and deactivating the catalyst.  An organozirconium compound is admixed with the polymer thus obtained.  The organozirconium compound is of the formula ZrOm(OCOR')n(OR")p-n where R' and R" are independently  selected from the group consisting of alkyl and cycloalkyl having 1-20 carbon atoms, and m = 0 or 1, provided that when m = 0, p is 4 and n is 0-4, and when m = 1, p is 2 and n = 0-2.  Any hydrocarbon solvent and other volatile matter are then separated and a composition comprising said high molecular weight polymer is recovered.  Alternatively the organozirconium compound may be blended with the polymer subsequent to the polymerization process. Examples of the high molecular weight polymers of alpha-olefins are homopolymers of ethylene, copolymers of ethylene with alpha-olefin homologues thereof, polypropylene and polybutene.

Title: Bone-grafting material
Inventor: NASHEF AWS S
IPC: A61F2/00
Filed: 1986-05-28
Granted: 1990-11-20
Abstract: Abstract A bone grafting material is derived from allogenic or xenogenic bone by a process that includes tanning with glutaraldehyde.  The bone may be pulverized, used as a large block, or machined into a precise pre-determined shape, depending on the bone defect to be repaired. Glutaraldehyde tanning of bone yields a stabilized, highly biocompatible, and non-antigenic materral which becomes incorporated into host bone when placed adjacent to it.

Patent CA-1280165-C (CA)
Inventor: SIERON RICHARD L
IPC: H02J9/00
Filed: 1986-11-04
Granted: 1991-02-12
Abstract: ABSTRACT OF THE DISCLOSURE      A self contained sensor module mounted on a power transmission line.  The module is capable of measuring various parameters such as line current, voltage, conductor temperature, and ambient temperature.  The parameter values are processed by sensor electronics which digitize and transmit the values to a ground receiver.  The sensor module normally derives its power through electromagnetic induction resulting from current flowing through the transmission line.  The module contains a power back-up system, including a battery, which allows sensor operation with minimum current and zero current in the transmission line.  The battery is float charged while the sensor is mounted on the transmission line using excess energy derived through electromagnetic induction.  When line current drops to a predetermined minmum value, float charging is disabled and the battery supplies power to the sensor module. When battery power is depleted to a predetermined level, data processing and transmission are disabled until the battery can be recharged.

Title: Air dryer purge control for turbocharged compressors
Inventor: SZUDY JAMES E
IPC: F04B49/18
Filed: 1987-05-27
Granted: 1992-06-30
Abstract: Abstract of the Disclosure A compressed air system includes an air compressor the inlet of which is communicated to the vehicle engine turbocharger.  The outlet of the air compressor is communicated through an air dryer to a storage reservoir.  A governor is responsive to the pressure level in the reservoir to generate an unloading signal unloading the air compressor when the pressure in the reservoir attains a predetermined value.  The unload-ing signal is also communicated through a control valve to purge the air dryer during compressor unloading.  The control valve closes communication between the governor and the air dryer to trap a predetermined pressure level in the purge volume of the air dryer to prevent the air dryer from purging to atmospheric pressure.  Accordingly, a predetermined air pressure level is maintained in the purge volume, so that the outlet of the turbocharger can never be communicated to atmospheric pressure.

Title: Overhead cable transport installation, especially aerial cableway
Inventor: FEUZ FRITZ

Granted: 1991-01-02
Abstract: INVENTORS:  FRITZ FEUZ and FERDINAND HORA            INVENTION:  OVERHEAD CABLE TRANSPORT INSTALLATION, ESPECIALLY             AERIAL CABLEWAY                  ABSTRACT OF THE DISCLOSURE     At each station of the overhead cable transport installation the vehicles which have been released or unclamped from the conveying cable are decelerated or accelerated by pneumatic wheels.  Between the V-belt drive and the hub of each pneumatic wheel there is arranged a free-wheeling clutch or slip coupling equipped with a pre-biased restoring or return spring.  The free-wheeling clutch transmits in one direction the torque or rotational moment from the V-belt drive to the pneumatic wheel without play.  In the opposite direction such free-wheeling clutch rotates against the restoring moment of the pre-biased restoring spring.   As a result there is eliminated the slip and the resultant wear of the pneumatic wheels upon the friction plate with which they come into contact during such time in which two neighboring pneumatic wheels engage with the friction plate.

Title: Method and apparatus for controlling the frequency of operation and at least one further variable operating parameter of a radio communications device

Granted: 1991-04-23
Abstract: METHOD AND APPARATUS FOR CONTROLLING THE FREQUENCY OF OPERATION AND AT LEAST ONE FURTHER VARIABLE OPERATING    PARAMETER OF A RADIO COMMUNICATIONS DEVICE                    ABSTRACT OF THE DISCLOSURE    The operating frequency of a radio transceiver and at least one further variable operating parameter of the radio transceiver are controlled in accordance with pre-stored information.  Transmit operating radio frequency information is stored in a memory together with associated optimum modulation deviation level information (e.g., so as to maintain a predetermined modulation level at each operating frequency).  Receive operating radio frequency information is similarly stored in the memory along with information indicating whether microprocessor clock oscillator frequency is to be shifted (e.g., so as to avoid spurious interfering harmonics emanating from the clock).  When operating in the transmit mode, pre-stored modulation gain level information associated with the selected transmit frequency controls the gain of the modulator circuits to compensate for expected changes in modulator circuit gain with change in transmit radio frequency.  In the receive mode, the microprocessor clock oscillator frequency may be shifted in accordance with the selected receive frequency, thereby automatically shifting harmonics of the microprocessor clock oscillator out of the receiver bandpass when necessary to avoid locally-generated signals from interfering with signal reception.

Title: Relay, cooking apparatus using the same, and power reducing method thereof
Inventor: SASAKI AKIMASA
IPC: H01H47/04
Filed: 1987-11-25
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE    A relay includes a internal power reducing mechanism for automatically reducing the power consumption of the relay without any extra power reducing circuit.     The relay includes a pair of relay contacts for alternately opening and closing with respect to each other, an electromagnetic coil for generating a magnetic force, a switch member and at least one coil terminal for controlling the current level in the electromagnetic coil ,and a movable contact plate.     To reduce the power consumption of the relay, in response to the magnetic force of the electromagnetic coil, the movable contact plate simultaneously moves one of the relay contacts with respect to the other and the switch member with respect to the coil terminal.     By this movement of the movable contact plate, the pair of relay contacts are closed, and a part of the electromagnetic coil or a resistor connected in series with the electromagnetic coil is short-curcuited. As the result, a holding current level is limited less than a driving current level.     A cooking apparatus ,such as,e.g. a microwave oven, can be made more compact and cheeper with this relay in a control device.
