Title: Procedure for Physical Decolouration of Blood
IPC: A23L5/49
Filed: 1979-02-20
Abstract: An emulsion of blood and fat is subjected to a considerable drop in pressure of the order of 200-300 atmospheres whereby the red blood corpuscles become covered by a protein/fat film and are thereby discoloured. The effect is enhanced by including in the emulsion small quantities of milk proteins e.g. sodium caseinate, or vegetable proteins e.g. soya protein isolates. Addition of the protein is necessary when the pressure treatment is applied to centrifuged-off red corpuscles instead of whole blood. The mixture of blood and fat and other ingredients is preferably heated to a temperature in the range of 30-70 DEG C prior to the pressure treatment. Referring to the drawing, blood from a drained animal is mixed in tank 17 with protein from silo 11, fat from conveyor 16 and water, and the mixture is passed through an emulsifier 22 and then to an homogeniser 24 in which the pressure treatment is carried out. <IMAGE>

Title: A thermally stable bumper finisher structure
IPC: B60R19/04
Filed: 1979-08-24
Abstract: A bumper comprises an elongated shock-absorbing member (70), and an ornamental finishing assembly (80), made of a different material from the shock-absorbing member, and supported on an elongated surface thereof.

Title: Data processing system including internal register addressing arrangements
IPC: G06F9/30
Filed: 1979-09-29
Abstract: In a multi-processor system of the type in which each processor is provided with its own unique bus which has an addressing system organised in such a manner that all store locations and peripheral equipments are addressed as part of a comprehensive single addressing system. Each address comprises a module number and an offset address. Each module in the system includes a module number comparator which detects the presence of its module address on a CPU bus and allows the offset address to be active within that module. The invention provides for the incorporation of similar mechanisms within a CPU allowing the CPU to address its own internal registers in an identical manner to its normal bus addressing mode. In addition the offset address includes a "bit portion address" which selects a mask which is used when performing the required internal register operation. The main advantage of such an arrangement is the simplification of the instruction range for the CPU as "normal" instructions may be used to manipulate the internal registers rather than having special purpose instructions dedicated to the manipulating of the registers.

Title: Valves
IPC: G05D7/01
Filed: 1979-11-21
Abstract: A shower mixture tap, including a pressure responsive flow control device for regulating the cold water feed for mixing with a hot water supply, comprises a valve assembly movable between an off position in which a washer 33 abuts a seating 42, and a maximum flow position in which the flow passes between a fluted portion 43 of the valve assembly and an O-ring 35, via an intermediate closed position in which the O-ring 35 engages a cylindrical portion of the valve assembly to prevent the flow. The cross-sectional area of the fluted portion 43 varies along its length so that the rate of flow can be adjusted by moving the valve assembly. The O-ring 35 is responsive to supply pressure to compensate for pressure variations. The valve assembly incorporates a jumper pin 31 movable by a spindle 36 located by a gland 37 of the tap. <IMAGE>

Title: Improvements in or Relating to Systems for Producing Compressed Air
IPC: G05D16/16
Filed: 1980-05-01
Abstract: A compressed air system having a reservoir 14 charged by a compressor 1 has an intake throttle 5 controlled in response to the pressure prevailing in the reservoir 14. Intake throttle 5 is either progressively controlled by a piston 7 loaded by a spring 10 and subjected to reservoir pressure through a line 12, 15 or moved between fully open and closed positions by pulses emitted by a two- state regulator (17) responsive to reservoir pressure. A fixed throttle in parallel with the intake throttle allows some air to enter the compressor when the throttle valve is closed thereby to inhibit oil escaping from the compressor. The system is preferably used in compressed air brake systems of motor vehicles. <IMAGE>

Title: Attenuator employing a digital- to-analog converter
IPC: H03M1/00
Filed: 1980-05-29
Abstract: An attenuator employing a digital-to-analog converter 10 has the switching of n successive stages of a bit weighting resistor network controlled by a first control signal 40 and the particular group of n successive stages from the total number N of the stages are selected by a second control signal 44. The attenuator comprises a 17-bit multiplying-type D/A converter 10 having an R/2R ladder network to set the bit weights, and controlled by a 6- bit remotely-generated command signal to vary the attenuation in steps of 1.5 dB through a range of 88 dB. The 1.5 dB steps are controlled by a 4-bit code signal responsive to two bits of the command signal. The 4-bit code signal is directed to four successive bit input terminals connected to digital lines 14 of the converter. Which four D/A converter input terminals are selected is controlled by a shifting matrix 50 which shifts the four bits along the D/A converter input terminals to a position determined by the other four bits of the command signal. <IMAGE>

Title: Improvements in rear view mirror assemblies for motor vehicles
IPC: B60R1/06
Filed: 1980-06-16
Abstract: A motor vehicle rear-view mirror assembly has a mirror carrying arm 2 swivelly connected to an attachment member 3 by a pivot pin 4. The attachment member 3 has oblique faces 16 urged by a spring 12 against cam surfaces within a boss 18 on the arm 2 tending to restore the arm 2 to an indexed position when angularly disturbed. An upward extension 11 of the attachment member extends into the arm to provide a journal bearing and a housing for the upper part of the spring. The attachment member 3 is secured to a hollow base 5 by a nut 10 which together with part of the attachment member 3, is contained within the hollow base 5 which does not need to be overlarge. The base can be fixed on a vehicle wing by self-tapping screws. This avoids the need for a large hole in the wing to receive the attachment member 3 or for access to the underside of the wing but the assembly is equally capable of being mounted direct on the vehicle by the attachment member 3 and a nut underneath the wing. <IMAGE>
