Patent GB-2078420-A (GB)
Title: Testing coins
IPC: G07D5/08
Filed: 1981-06-08
Abstract: The invention relates to a coin validator for use in a micro-processor controlled call coin box telephone instrument. The validator comprises first and second coil sets driven by square wave interrogation pulses. The arrangement of the coils is such that when a coin is in the coin-runway of the call coin box, one coil pair is used to interrogate the coin in the runway while the other coil pair provides environmental conditions apertaining to the runway. The information generated by both coil sets is combined thereby compensating for environmental changes and drift. Information pertaining to the relative response times of the secondary coils is then used to determine coin validity.

Title: Vibratory method for packing foundry sand into a pattern prior to the pouring of molten metal
IPC: B22C9/04
Filed: 1981-06-29
Abstract: The invention relates to the casting of molten metal where a pattern embedded in sand is used to determine the shape into which the molten metal is formed. To ensure that the foundry sand fully penetrates all cavities and recesses of the pattern, the mold flask containing the pattern and sand is first vibrated at a frequency and stroke to produce accelerations in excess of the acceleration due to gravity to cause the sand to penetrate and completely fill all cavities, etc., in the pattern and then the accelerations are reduced to produce an acceleration less than the acceleration due to gravity to compact the sand in place. <IMAGE>

Title: Weighing apparatus
IPC: G01G3/14
Filed: 1981-07-10
Abstract: Apparatus for weighing a load comprises a composite member in which a strain gauge is located so as to be subjected to a strain induced in the composite member by the load. Signals from strain gauges A1, A2, etc are sent to receiver means, such as analogue-to- digital converter 84 which converts the signal for transmission to display means, such as a micro-processor 81, which provides a visual or audible indication of the applied load on the composite member. The composite member may be, or form part of a suspension spring of a vehicle so that the signals represent the load on an axle of the vehicle, which is then registered on the display means. Individual indication of the load applied to each of several composite members may be provided, or a selected combination of the loads may be indicated. <IMAGE>

Title: Tube pressure filter
Inventor: MARTIN JOHN LAWRENCE
IPC: B30B9/22
Filed: 1981-07-20
Abstract: The slurry inlet (22) of a tube pressure filter is formed in the inner tubular assembly (17, 18, 19) of the filter, and after introduction of slurry the inner assembly is moved upwards a short distance (Fig. 3 not shown) to an operative position in which contact of the inflatable membrane (5) against the inlet (22) is prevented by positioning of the inlet (22) within an annular shield formed by upper end ring (7) of the outer assembly, thus obviating damage to the membrane by its being pressed against the edges of the inlet (22). After the filtering and pressing, the inner assembly is moved down out of the outer assembly to discharge the cake. <IMAGE>

Title: Damp proofing of walls
Inventor: BACINSKA ALICIA
IPC: E04B1/70
Filed: 1982-04-26
Abstract: Damp proofing of a wall 1 is affected by means of an electro- osmotic installation, which is supplied by a source 7 with an alternating voltage with a positive average value for the period. The voltage is applied to electrodes 4 in the wall 1. A hydrophobic agent such as silicone is supplied to sloping holes 8 in the wall. The dynamic and impulsive action of the alternating voltage increases remarkably the speed of the drying process and the range of penetration of a hydrophobic agent, orders and imparts dynamism to water particles, diminishes the occurrence of electrode corrosion and assures also drying and sealing of pores which are very small and vary in size. <IMAGE>

Title: Apparatus and method for utilizing hot waste gases
Inventor: FORESTO SAMUEL
IPC: F23G7/06
Filed: 1982-05-07
Abstract: The present invention relates to improvements in the utilization of heat from waste gases. In apparatus for utilizing the heat of waste gases from a source 12, the gases are exhausted at the head of a flue 14 from a source into a heat extractor 22 where the hot gases are caused to move and turbulate about the walls of heat exchange means to release their heat to such walls before being exhausted in a downward direction to the atmosphere through outer duct 51 so that fluid e.g. air, water moved through the heat exchanger may be heated. The heat exchange surfaces may be cleaned by applying suction or pressurized air to a series of pipes 63 having nozzles 64. <IMAGE>

Title: Determination of print area of a printing master
Inventor: MORGENSTERN BERND
IPC: B41F33/00
Filed: 1983-12-01
Abstract: A method of determining the print area portion of a printing original, outside or inside a printing machine, with the use of incident or transmitted light comprises the step of initially tightening the original on a curved or planar support by means of a mechanical tension force. A row of photoelectric diodes (2.1 to 2.5) on a rail (8) are calibrated simultaneously by calibration standards (3, 4) extending transversely of the diode conveying direction before movement of the row into the printing image region of the original. The original, divided into columns (1.1 to 1.5) is then scanned in small areas starting in all columns at the same time, and the resulting measurement values are stored in a computer and integrated for the purpose of formation of the desired indication of the print area. <IMAGE>

Title: Weight control unit for concrete mixing plant
Inventor: MARCON GERARDO
IPC: G01G23/37
Filed: 1983-12-15
Abstract: The control unit (10) comprises in coordinated cooperation:    a one-pendulum balance beam (14), a transducer (19) to monitor the value of the displacement of the one- pendulum balance beam (14) and to convert that value into an electrical analogue signal, an analogue-digital converter to convert that signal, and a numerical display, programming means to pre-set the weight for each constituent to be weighed and a comparator to compare the value monitored with the pre-set value. The procedure for reading weight values using the weighing scale control unit (10) is one in which an analogue signal coming from the transducer (19) is converted into a digital signal by the converter and is then compared by the comparator with a value pre-set on the programming means in relation to the constituent being weighed.

Patent GB-2157613-A (GB)
Title: Moulding synthetic plastics wheels
Inventor: OLEFF WERNER
IPC: B60B5/02
Filed: 1984-04-16
Abstract: The synthetic plastics wheel consists of a rim (1), several spokes (2) and a hub (not shown) and is produced in one piece by injection-moulding from the hub. Between each two adjacent spokes (2) the rim possesses a wall part (6) extending in the rim circumferential direction which extends from the attachment point (5) of each spoke to the rim to the centre (IV-IV) of the rim section between the two spokes. The wall part (6) is of greater cross section than the outer rim walls (3,4) so that the plastics material flows more rapidly from the two spoke attachment points (5) to the middle of wall part (6) than do the two circumferential currents of synthetic plastics material advancing in the remaining rim walls (3,4). The material in wall part (6) then flows radially into rim walls (3,4) which prevents the two circumferential currents in the rim walls (3,4) meeting in the rim section centre with formation of a cold flow seam which would considerably reduce the strength of the rim at the rim section centre. <IMAGE>
