Title: Detection apparatus
Inventor: DIVER JOHN
IPC: G08B13/24
Filed: 1967-06-27
Abstract: 1,234,762. Photo-electric nonitoring; proximity switches. J. DIVER. June 14, 1968 [June 27, 1967; Aug. 12, 1967; Sept.22, 1967; Nov. 4, 1967], Nos. 37146/67, 43220/67, 50218/67, 29533/67. Headings G1A and G1N. [Also in Division G4] Apparatus responsive to a change in a magnetic field comprises a pivoted magnetic member arranged to lie in a particular position due to the earth's or other magnetic field in relation to a beam of light impinging on a first photo-electric cell, deflection of the member causing change in the current through the first photo-electric cell; a galvanometer being deflected by the first photo-electric cell output, the pointer of the galvanometer affecting a beam of light impinging on a second photo-electric cell. As shown in Fig. 5, a magnetized needle 1 is arranged to be responsive to changes in a magnetic field and so to vary the amount of interruption between light from a lamp 6 and a photo-cell 7. The current in photo-cell 7 is monitored by a galvanometer 11, the pointer of which controls the light emitted by a lamp 12 on to a further photocell 13. A sufficiently large variation in the magnetic field will thus energize relay 14 which operates visual and/or audible alarms, (not shown). A second needle 31 prevents false indication due to daily changes in the earth's magnetic field. The magnetized needle 1 may carry a slotted disc Fig. 3, (not shown) which varies the amount of interruption of the beam from lamp 6. Applications. The detector may be positioned near the exit of a supermarket in which the goods are arranged to carry magnetized labels which are normally removed by the cashier so that an alarm is given if an attempt is made to remove such goods through the exit without prior payment. The invention is also applicable to burglar alarms by detecting the opening of a Forrows metal framed window or door or a wooden closure provided with an element of such material. Reference is also made to applications including the automatic operation of garage doors, detection of low flying aircraft, submarines or iron ore or the supervision of animals or prisoners.

Abstract: 1363906 Laminated springs R SOHNATMEIER [trading as HEINRICH SCHOMACKER & CO] 2 Nov 1971 [6 Nov 1970] 50843/71 Heading F2S A spring, e.g. for a lorry or trailer, has a number of leaves 2 each having a cranked portion 5 so that a surface 10 bears against and supports an adjacent leaf, there being gaps 9 between the leaves because of inserts of metal or synthetic material interposed at the central fixing point 3. As shown, the ends 11 are reduced by rolling and, in the unloaded state indicated, the bearing surface 10 is small but this (and thus damping-friction) gradually increases with loading until at full load, the leaves are horizontal and the whole of the top surface of each of the ends 11 supports an upper leaf. Some at least of the ends 11 may be unreduced and differ in length and be flat against an upper leaf at all loads. The leaves 2 may be of rectilinear outline or of parabolic design.

Abstract: 1,273,894. Centrifugal pumps. NORTH AMERICAN ROCKWELL CORP. Oct. 28, 1970 [Dec. 29, 1969], No.51294/70. Heading F1C. A pump assembly comprises a container divided into two compartments 14, 16, Fig. 2, each containing a respective pump 40, 50, e.g. of the centrifugal type shown. Liquid is drawn through a duct 18 and valve assembly 20 into compartment 14 by the suction created therein by pump 40, the suction also keeping the valve assembly 20 open via diaphragm 32 exposed to the closed chamber 14 and to the chamber 16 which is permanently vented to atmosphere at 17. The valve assembly also includes a non-return valve 22. The pump 40 delivers the liquid through conduit 46 into compartment 16 from where it is discharged via conduit 58, Fig. 5, flow-metering valve 82 and outlet 59. Compartment 16 contains a float assembly 60 which opens a valve (70), Fig. 3 (not shown), to directly communicate the compartments 14, 16 with each other through a passage (76) in partition 13, when the liquid level in compartment 16 reaches a predetermined value. Thus, the suction in compartment 14 is neutralized causing closure of valve assembly 20 until the liquid level falls.

Patent GB-1492139-A (GB)
Title: Data processing system
IPC: H04M3/36
Filed: 1975-12-18
Abstract: In the data processing system containing a computer urgent tasks are processed in real time, that is to say at the instant at which they occur. However, this process may be found to be inadequate for protecting the computer against work overload during high traffic demand. The degree of occupancy of the computer is therefore determined by measuring the idle unoccupied time between repeated executions of a particular basic program of the lowest class of priority. The idle unoccupied time between time intervals of 10ms is measured in units of 25  mu s and compared with an upper and a lower limit value. Depending on the result of the comparison, the work load is reduced, left unchanged or increased. The system is used, in particular, for telecommunication switching purposes.
