Patent GB-2045654-A (GB)
Title: Work holding mechanisms
IPC: B23Q3/18
Filed: 1980-02-29
Abstract: A mechanism for holding a workpiece in position during an operation being performed by an operating device passing along the workpiece includes a toggle linkage (1, 2, 3), a projecting member (9) attached to the device, and a cam track (2) connected to one part of the toggle linkage, the arrangement being such that, towards the end of the pass of the device, after it has completed its operation on the workpiece, the projecting member (9) engages the cam track (2), further movement of the device causes the projecting member (9) to move the middle pivot (3) of toggle linkage to release it and, hence, release the workpiece as the device completes its pass. Preferably the toggle linkage is arranged as an over-centre toggle linkage with its other component formed by a telescopic arm (1). <IMAGE>

Title: A governor for a fuel injection pump
IPC: F02D21/08
Filed: 1980-03-06
Abstract: A fuel injection pump (2) for an internal combustion engine, has a speed governor whose adjusting member (13) is subject to speed dependent fuel pressure from a pump (16) which acts against the force of two spring units (15, 28). In order to simplify the governing of the starting quantity the invention provides that one of two spring units serves as a starting spring (28) which acts directly on the adjusting member, and a second, acts upon the adjusting member by way of a spring abutment plate 24, which plate, when in its initial position abuts against the housing. <IMAGE>

Title: Analysis of constituents of earth formations
IPC: G01V5/10
Filed: 1980-08-11
Abstract: The composition of an earth formation is investigated by repetitively irradiating the formation with bursts of neutrons from a source 22 and measuring an energy spectrum of the scattering gamma rays resulting from such irradiation e.g. by photomultiplier or solid state detector 24. The measured spectrum is thereafter analyzed by comparing it with a composite spectrum, made up of standard spectra, measured in a controlled environment, of constituents postulated to comprise the formation. As a result of such analysis, the proportions of the postulated constituents in the formation are determined. Since the measured spectrum is subject to degradation due to changes in the resolution of the detector, a filtering arrangement effects modification of the standard spectra in a manner which compensates for the changes in the detector and thereby provides for a more accurate determination of the constituents of the formation. Temperature is measured by sensor 46 to compensate for temperature dependence of detector resolution. <IMAGE>

Title: Packaging
IPC: B65B53/06
Filed: 1981-06-03
Abstract: A package is formed by loading a bag, preferably of heat-shrinkable material, in a vacuum chamber 2,3 and operating hot air fans 9 to circulate air over heats 16 within the closed chamber to apply heat which causes air trapped within the container by bag- mouth restoration means 33,35, to expand and balloon up the container away from contact with the product (21) so that further forced convection heat is more readily able to shrink back the bag into contact with the product. The closed, ballooned bag is then ruptured, the chamber evacuated, and the bag finally sealed before repressurisation and opening of the chamber. The bag mouth restricting means may comprise a resilient leaf 33 biassed against a counter-support to releasable hold the bag-mouth closed whilst allowing venting of any excessive pressure built-up in the bag. <IMAGE>

Title: Circuit arrangement for deriving a field synchronising signal from a composite television synchronising signal
IPC: H04N5/10
Filed: 1981-11-18
Abstract: A circuit arrangement derives a field synchronising signal from a composite television synchronising signal which is applied to a monostable multivibrator 2 and to a delay element 6. The resultant pulses are applied to a gate circuit 4 the output signal of which does not contain line synchronising pulses. To this end the duration of the pulse generated by the multivibrator 2 is at least equal to the sum of the duration of a line synchronising pulse and the delay ( tau ) produced by the delay element 6, which delay is longer than the response time of the multivibrator. The output signal of the gate circuit 4, for example a NAND-gate, may be applied to a second multivibrator 8 for generating a pulse the duration of which is at least equal to the duration of the field synchronising interval. <IMAGE>
Patent GB-2093245-A (GB)
Title: Nuclear reactor power supply system
IPC: F22B35/00
Filed: 1982-02-04
Abstract: The redundant signals from the sensor assemblies (61, 69,...) measuring the process parameters of a nuclear reactor power supply are transmitted each in its turn to a protection system (53) which operates to actuate the protection apparatus (57) for signals indicating off-process conditions. Each sensor assembly includes a number of like sensors measuring the same parameters. The sets of process signals derived from the sensor assemblies (61, 69,...) are each in its turn transmitted from the protection system to the control system (55) which impresses control signals on the reactor or its components to counteract the tendency for conditions to drift off-normal status requiring operation of the protection system. A parameter signal selector (111, 113) is interposed between the protection system and the control system. This selector prevents a parameter signal of a set of signals, which differs from the other parameter signals of the set by more than twice the allowable variation of the sensors which produce the set, from passing to the control system. The selectors include a pair of signal selection units, one unit (111) sending selected process signals to primary control channels (141) and the other (113) sending selected process signals to back-up control channels (143). Test signals are periodically impressed by a test unit (115) on a selected pair of a selected unit and control channels. When test signals are so impressed the selected control channel is disabled from transmitting control signals to the reactor and/or its associated components. This arrangement eliminates the possibility that a single component failure which may be spurious will cause an inadvertent trip of the reactor during test.

Title: Self-loading hand weapon
Inventor: JAKUBASCHK HORST
IPC: F41A3/72
Filed: 1983-05-06
Abstract: A self-loading hand weapon, preferably a rifle, with a locking means exhibiting a lever for locking a movable weapon part as a function of the position of another weapon part is characterized by the fact that the lever is a double-arm lever which, with one of its arms, is basically constantly in contact with the movable weapon part and, with its other arm, is in contact with the other weapon part. Consequently, no springs are required for positioning the lever. As shown in Figure 8, the lever 114 is controlled by a cam 54 and serves to lock the rotary breechblock 4 in the appropriate position. In another section of the weapon (Figure 10, not shown) a double-arm lever (135) controlled by a cam (56) serves to lock the firing hammer (66) in the cocked position. <IMAGE>

Abstract: A fuel treatment device for an internal combustion engine includes a casing 17 which contains a treatment medium such as a filter element 18. Water collects in a space 22 in the casing and is drawn from the space through a tube 24 connected to the throat 23 of a venturi, by the flow of air through the venturi. The air flow is produced by connecting the venturi across the air filter 16 in the air intake line of the engine. As shown, a float- operated switch controls valve 27 to actuate the venturi when water accumulates. In Fig. 2 (not shown) the venturi is permanently connected to the air line, but a float-operated valve opens and closes the lower end of tube 24. <IMAGE>
