Title: A livestock identification system
Inventor: NORTHEVED ALLAN
IPC: A61B5/117
Filed: 1982-12-14
Abstract: A registering system in the form of a communication system with means on the transmitter side for the transmission of a phase-modulated high frequency signal. A receiver in a sensor includes an electronic relay (5) supplying the remaining circuits in the sensor with energy at the receiving of a signal. The remaining circuits phase- detect (at 7) the received signal to produce a pulse for each period, the number of pulses being counted and compared with a predetermined value in the sensor and a signal being transmitted in case of identity. The frequency of the signal transmitted is preferably the second harmonic series of the signal received, a loop on the transmitter side being arranged to produce the same harmonic series of the modulated transmitted signal. The signal received and the harmonic series are transferred to a multiplier (12), the moment of a possible signal transmission from the multiplier corresponding to the predetermined value in the sensor. <IMAGE>

Patent GB-827789-A (GB)
Abstract: 827,789. Jet propulsion plant. ESCHER WYSS A.G. July 12, 1957 [July 19, 1956], No. 22171/57. Class 110 (3). An aircraft jet propulsion plant comprising a ducted fan driven by a main turbine of a closed cycle power plant in which a gaseous working medium is compressed in a compressor driven by the main turbine, heated in a heater, expanded in the main turbine and then cooled before being re-compressed in the compressor, has one or more additional fans driven by additional turbines mechanically independent of the main turbine but included in the closed gas circuit. The additional fans may be used for producing additional propulsion jets, influencing the boundary layer by suction or blowing, cooling components, producing air jets for the parts of guide mechanisms or for braking the aircraft in flight or during landing. A ducted fan 3 is driven by a main turbine 4 of a closed cycle gas turbine plant having a gaseous working medium such as air, helium or other gas. The gas is compressed in a compressor 5, heated indirectly in a heater 7 and then expanded in the turbine 4. The heater 7 may be heated by burning fuel in which case the heater may be arranged in the combustion chamber of a gas turbine jet propulsion engine. Alternatively, the heater may be heated by atomic nuclear reaction. To supply additional air under pressure, additional fans 9 driven by additional turbines 10 are provided. These turbines are mechanically independent of the main turbine 4 and traversed by the working medium of the closed circuit. The turbines 10 may be arranged in parallel with each other and in series with the turbine 4. The gases expanded in the turbines 10 are cooled in the cooler 13 by the air from the ducted fan 3 before being returned to the compressor 5. The cooler 13 may be arranged elsewhere in the aeroplane such as in the air flow from the fans 9. The additional turbines 10 may be arranged in parallel with the turbine 4 or the turbine 4 arranged in series behind the additional turbines 10.
Patent GB-2117246-A (GB)
Title: Vascular prosthesis
Inventor: HOOD ROBERT GORDON
IPC: A61F2/06
Filed: 1983-03-22
Abstract: An artificial vascular prosthesis is made by winding a thread around a tube (3) of warp knitted textile thermoplastics material held on a rigid former (1), removing the thread, then immediately applying an axial thrust to the tube to reduce the length of the tube by formation of corrugations (8) and then heat setting the material of the tube in its corrugated condition. Removal of the thread before compressing axially the tube material allows the tube material compressed by the encircling thread to relax while immediate application of the axial compressive thrust causes the tube to corrugate before the memory of the pressure applied by the thread has had time to dissipate. The finished prosthesis thus has corrugations without any reduction in pore size. <IMAGE>

Title: Determining refractive index of a liquid
Inventor: TAKEDA REIJI
IPC: G01N21/43
Filed: 1983-03-30
Abstract: Light from a source 6 is directed via a lens 7, a transparent body 2 having a light inlet 2, an arcuate interfacial wall surface 5, and a light outlet 4, to a photoelectric light receiving element 8. In use, the body 2 is immersed in a liquid 1 and the amount of light reflected from the wall surface 5 and detected by the element 8 is determined by the refractive index of the liquid. The wall surface 5 has a radius which is selected so that light L advancing along a guide wall 9 of the inlet 3 is incident on the wall surface 5 at the critical angle for a prescribed condition of the liquid. For example, when measuring the concentration of sugar solution, the prescribed condition may be zero concentration. In a second embodiment inlet 2 and outlet 4 are replaced by optical fibers; light from the outlet fibre is visually compared with light received from the source via a variable attenuator (20) and a further fibre (17); the setting of the attenuator for equal light intensities is an indication of refractive index. <IMAGE>

Patent GB-2164659-A (GB)
Title: Hydrocarbon conversion process
Inventor: MURPHY MARTIN ANTHONY
IPC: C10G11/00
Filed: 1984-09-24
Abstract: A hydrocarbon chargestock (11) is separated by distillation (12, 16), at least in part under reduced pressure, into a conversion feedstream (22, 24) and a vacuum residuum (17). The feedstream is converted at an elevated temperature in a conversion unit (25), e.g. a fluidized catalytic cracking system, to high temperature conversion products (26) which are passed into the bottom region of the lower portion (27) of a fractionation tower (28). The vacuum residuum (17) is passed (via 50) into the top of the lower portion (27) of the fractionation tower (28). Heat and mass transfer within the lower portion (27) of the tower desuperheats the conversion products and also strips from the vacuum residuum lower boiling materials thereby increasing the amount of useful hydrocarbon distillates recovered from the tower (28) and decreasing the amount of low value high boiling residue (30) discharged from the bottom of the tower and which is discarded for use as a fuel oil component and/or a feed for a subsequent conversion process. The amount of cooling of high boiling materials (e.g. in heat exchangers 19, 33) is considerably reduced compared to known hydrocarbon conversion processes. <IMAGE>

Patent GB-2154351-A (GB)
Title: Coding workpiece carriers in production plant
Inventor: STICHT WALTER
IPC: B23Q41/00
Filed: 1985-02-06
Abstract: Workpiece carriers (4) are fed to successive work stations (2) along conveyor tracks (13) at which stations (2) work operations are performed on individual parts (5) on the carrier (4) and in which a defect signal is allocated when appropriate. After a work operation has been performed a coding member (22) is left in a normal switching position corresponding to a defect coding or displaced into a switching position corresponding to an accept coding if the work operations performed were satisfactory. In a coding device displaceable coding elements (22) are supported by a workpiece carrier (4) and traverse a detector device (10) at the work processing station (2) and a switching element (10) for displacing the coding element (22) from a reject coding switch position to an accept coding switch position. An accept coding is consequently secured only by a deliberate action when satisfactory work processing has been completed and thus subsequent processing of defective parts is avoided simply and with great reliability. <IMAGE>

Title: A method of and apparatus for generating speed commands for an elevator
Inventor: TAKAHASHI HIDEAKI
IPC: B66B1/16
Filed: 1986-03-27
Abstract: The generation of speed commands for an elevator, in which the transition from a time-base speed pattern generated on a desired acceleration to a distance-base speed pattern (v1) produced by a first pattern generator (101) so as to decrease over the remaining distance between a present position of an elevator cage (7) and a stopping position at a desired deceleration. When the next floor to be served is determined a distance-base speed pattern (v2) is produced in a second pattern generator (102). A detector (103) compares the outputs of the two pattern generators to detect a speed difference (dv) and produces an output to a generator (104) and switching means (106). A subtractor (105) executes the subtraction of the speed variation calculated in generator (104) from the distance based speed pattern (v2) produced in generator (102), whereby a transition pattern smoothly interpolating the two speed patterns can be generated. <IMAGE>

Title: Radiographic apparatus
Inventor: LEES JAMES LESLIE
IPC: G01S17/08
Filed: 1986-05-08
Abstract: In some systems, where an X- ray image of a subject is produced on photographic film, the X-ray emitter (4) has to be positioned precisely relative to the photographic film (2) and the subject (3) under inspection, the distance between the X-ray emitter and the film needing to be accurately set. This distance is known as the film-to-focus distance (FFD) and is related to the intensity of the X-ray beam. Deviations from an accurate FFD may result in over- or under-exposure of the film. An accurate FFD can be obtained by mounting a laser alignment system within the examination head (1) together with the emitter (4). A beam (12) from the laser (11) is split into two beams (14, 16) which are directed onto the surface (15) of the subject (3) under inspection. For a given FFD, the angle one beam (16) makes with the other (14) is directly related to the FFD and hence coincidence of the two beams (14, 16) on the surface (15) results in the FFD being accurately aligned to provide the correct exposure of the film (2). <IMAGE>

Title: A heating and/or cooling system
Inventor: KENT DEREK
IPC: F24F1/00
Filed: 1986-05-29
Abstract: A heating and/or cooling system has a system controller (10') and a number of heating and/or cooling sources (1-4), which may be multi- stage heat pumps, the heating and/or cooling sources being operated in parallel with respect to the delivery of the heated or cooled working medium. Each of the sources is controlled by an individual controller (5-1 to 5-4) which is issued with demand signals from the system controller. The system controller commands the sources to increase or decrease their heating or cooling capacity by comparing the temperature of mixed working medium from the parallel outlets (6) of the sources to preset reference values. The system controller sequentially energises or de- energises the sources so that at any time the only minimum number of sources which can satisfy the heating and/or cooling demand are energised. <IMAGE>
