Abstract: The invention relates to a device for separating vapour bubbles in the liquid fuel supply systems of internal combustion engines, with a housing which has a fuel inlet 101, a fuel outlet 105 and a cover 103 containing centrally a vertical vapour outlet 109. In the device:   (a) the fuel flows tangentially through an inlet 101 into a vortex chamber 104 formed by the housing of the device and its cover; (b) the fuel flows away tangentially from the vortex chamber through the outlet 105;   (c) the inlet is at a higher elevation than the outlet;   (d) the cover contains a steeply sloping channel 107; (e) the sloping channel communicates with an outlet pipe 109 rising axially upwards from the housing; (f) the sloping channel in the cover communicates with the vortex chamber through a bore 106, 108. A ball 110 having a density less than that of the liquid fuel but greater than that of the vapour partly obturates the mouth of the pipe 9 when the channel 107 is filled with liquid fuel.   <IMAGE>

Patent GB-2060965-A (GB)
Title: Portable alarm system
IPC: G08B29/04
Filed: 1979-09-25
Abstract: An alarm device for use by an elderly or infirm person includes an alarm transmitter (1) which is switched on by a wearer-operated push-button (5) to emit an alarm signal. This alarm signal is modulated, e.g. by a 1 KHz signal from an alarm modulator (3). This signal is responded to by a radio receiver (10), whose output is fed to an alarm trigger (13) via a switchable filter (11). To ensure that a fault in the alarm device, e.g. a flat battery, is detected, the alarm device has a further modulator (4), which is clock-controlled to emit a signal with a different modulation to that used for the alarm at preset intervals. At the receiver, these pulses are passed via a filter (12) to a delay timer (14), which operates a fault indicator when a preset number, e.g. two, of pulses have failed to arrive. This gives an indication, either to a warden or to the user, as a result of which the fault can be corrected. The circuitry to drive the timer (14) is also used to drive a clock display. <IMAGE>

Abstract: An apparatus for optically detecting bank-notes for use in a bank-note counting machine or the like includes a guide (8) provided along the passageway of bank-notes for making contact with the bank-notes passing along the passageway, and a photodiode (A1, A2) having its light-receiving part (A2) disposed in the guide (8) for optically detecting the bank-notes as they pass through the guide. A part-spherical glass member (B) is mounted over the light-receiving part (A2) of the photodiode with the top portion of the glass member projecting past the surface (8a) of the guide in the passageway of bank-notes. This top portion of the glass member (B) prevents dust carried by the bank-notes from accumulating on the light-receiving part of photodiode, the dust being swept from the top portion of the glass member by the passing bank-notes. <IMAGE>

Patent GB-2078368-A (GB)
Title: Sorting objects by colour
IPC: G01J3/51
Filed: 1980-06-20
Abstract: A colour detector system for sorting objects on the basis of their colour establishes the shapes of the spectra of light from a small area of an object to be tested and of a standard object, by means of a spectroscope (3) and a photo-diode array (4), and uses an analogue comparator (12), an error counter (14) and a further digital comparator (15) to make an accurate assessment of the similarity of the shapes of the spectra. The spectrum of the standard object may be held in a memory (10). The invention is particularly applicable to the sorting of banknotes, which may be worn through usage and consequently reflect light less strongly. The detector compares the shapes of the spectra of the test object and the standard object, rather than comparing the absolute magnitudes of intensity, and so is able to compensate for any differences in overall intensity due to different reflectivities. <IMAGE>

Title: Preparation of filler composition for dough moulding compounds
IPC: C08K9/08
Filed: 1981-03-17
Abstract: A filler for the manufacture of a DMC is prepared by mixing a finely divided substantially non-absorbent mineral filler with an aqueous emulsion or dispersion of a thermoplastic polymeric material. In order to prevent coagulation of the emulsion or dispersion upon mixing, the filler is treated with water before the mixing is carried out. The mixture is dried at elevated temperature to form a powder having the thermoplastic polymer homogeneously dispersed in the filler. A dough moulding compound can be made by mixing the treated filler with unsaturated polyester resin solution glass fibre and minor amounts of other additives. Good dispersion of the thermoplastic polymeric material in the DMC is thereby obtained.

Title: Method of and apparatus for the controlled cooling of a product
IPC: A01N1/02
Filed: 1982-04-08
Abstract: For the controlled cooling of specimens which are at least partially of liquid form, especially biological specimens, it is important that crystallization at the freezing point takes place locally, without supercooling, and preferably with absorption of the latent heat of fusion. A cooling device which comprises at least one module (28a, 28b) which operates in accordance with the Peltier effect, with the "cold" faces (36) of the modules connected by a conductive metal strip (38, 40), has the specimen container (24) in contact with the strip. The device is mounted in a working chamber which has its temperature/time profile controlled. At a temperature which is a predetermined amount above a given critical temperature for the specimen, e.g. its freezing point, the Peltier effect modules are energised to effect short-term supplementary cooling at a local area, for example one end, of the specimen (24). Other critical temperatures such as of sedimentation, can be used. <IMAGE>

Title: System for maximum efficient transfer of modulated audio frequency energy
IPC: H03G9/02
Filed: 1980-10-03
Abstract: An audio processing system for maximizing the efficiency of transferring audio frequency signals. Signals to be processed are supplied to a bandpass input filter (19), thence to a primary active frequency control (23). Its output drives a primary voltage compressor (27) selectively limiting audio dynamics to a predetermined window, the latter being controllably preset and driven with different audio bands of amplitude determined by the primary frequency control to maximum compression levels indicated by a visual indicator (33). The output of the primary compressor is presented to a secondary active frequency control (35) driving a secondary dynamic compressor (37) with different audio bands. A second visual indicator (50) indicates maximum compression levels of the latter. An automatic gain control (AGC) (29) tied to the secondary compressor supplies feedback to the primary voltage compressor via AGC circuitry to control primary compression as a function of average, overall dynamic compression of the system. The AGC circuitry also feeds a third visual indicator (45) which displays average compressed output voltage. The processed output of the secondary compressor is provided to a bandpass output filter (52) and, sharply frequency attenuated by the latter, is delivered for further use. A high level output stage (56) is also selectively utilized for driving auxiliary devices.
