Patent GB-682904-A (GB)
Abstract: 682,904. Turning-gear. KNOCKER - HUMBOLDT-DEUTZ AKT.-GES. Oct. 27, 1950 [Feb. 16, 1950], No. 26321/50.. Class 7 (v). In a spring starter for diesel engines comprising a toothed annulus 1, Fig. 1, on the spring casing of the starter and which is driven for tensioning or compressing the spring by an electric motor 2, Fig. 2, through a ratchet gear consisting of pawls 5, 6 actuated by eccentrics 3, 4, it is arranged that the shaft 20 on which the eccentrics are mounted is driven by the electric motor through a reduction gear 10-14. The eccentric 4 is in two parts, one part being arranged on each side of the other eccentric 3; the pawl 6 is similarly divided and surrounds the pawl 5. Secured to the spring housing, not shown, is a cam 17, Fig. 1, which disengages the pawls 5, 6 from the teeth 8 of the aninulus 1 when the spring is tensioned by impacting upon the roller 7 of the pawl 5, movement of the latter being transferred to the other pawl through a pin 18 and permits the spring to crank the engine; the position of the cam 17 may be varied and the teeth of the annulus are made of special material at the various locations of the :am in order to prevent undue wear at these places. The pawls are retained in the disengaged position by a spring-loaded pin 19 which is :oupled to the starting device of the electric notor 2 for conjoint operation of these parts.

Patent GB-2027347-A (GB)
Title: Tongue cleaner
IPC: A61B17/24
Filed: 1978-07-27
Abstract: The instrument has a 'U-shape' where the arc forms the active edge A and the ends are elongated to form two symmetrically centred handles B. A flexible strip form consists of a plastic strip which tapers to the centre and by this virtue enables one to flex it in order to obtain the arc and two handles this type is considered to be a disposable cleaner. In order to form a more commercial and compact package, a renewable strip form of the disposable cleaner is designed to fit into a specially constructed tooth brush handle. The two in one instrument complements the cleansing process of the mouth. It is important that these apparatus be designed with safety in mind.   They shouldn't be sharp or have corners, they would be plyable with a degree of resiliance and not be heavy. The handles be thin so that it would be manipulated with the fingers rather than be used with the weight of the hand. <IMAGE>
Patent GB-2027558-A (GB)
Title: Improvements in or relating to waveguide radiators
IPC: H01Q13/02
Filed: 1978-08-10
Abstract: The invention relates to a waveguide radiator in which a directional beam of electromagnetic radiation is formed by a hollow waveguide having an array of slot pairs 8, 9 formed in one of its broad walls, the slots of a pair radiating in anti-phase. The slot pairs 8, 9 are provided in at least those longitudinal regions of the waveguide radiator where a relatively low amplitude radiation is required, single slots being provided where higher amplitudes are required, so as to produce by amplitude- tapering a directional beam having only low amplitude sidelobes. By providing a pair of slots they can be positioned at regions of the waveguide where the change in amplitude or phase of the electrical field is not critically dependent on position. This reduces the manufacturing tolerances involved in producing a waveguide radiator. Asymmetry of the feed conditions of the two slots of a pair determines their net radiation amplitude and can be controlled by screws 10-13 or by the slot positioning. <IMAGE>

Title: Memory protection system using capability registers
IPC: G06F21/62
Filed: 1979-09-29
Abstract: The use of protected capability registers to hold the physical base and limit addresses and access rightsfora block of memory and the way in which such registers are loaded using System Capability Tables and reserved segment pointer tables is well known in the prior art. In the present invention the normal capability load instruction has been enhanced in four majorways:-a) allowing additional capability classes to be handledb) instituting a "load on use" facilityc) instituting capability propagation control andd) implementing access reduction facilitiesThe capability classes comprises (i) system store, (ii) system resource (iii) local store and (iv) passive capability. The "load on use" facility speeds up the load capability instruction and the change process instruction. The propagation control mechanism introduces an access bit which controls the storing of the capability pointer preventing the passing of the pointer from one process to another whereas the hardware access reduction facility enables a capability to be loaded into a a capability register with reduced access right.
Patent GB-2060779-A (GB)
Title: Rotary positive-displacement fluid-machines
IPC: F02B75/02
Filed: 1979-10-12
Abstract: In order to provide scavenging in the cylinder(s) 2 of an I.C. engine a lobe 4 is mounted on a rotary part of the engine, which may be the flywheel 1,which is driven by the crankshaft. The lobe runs in a channel 5 surrounding the flywheel 1 and communicating with the cylinder air- inlet port(s). As the lobe moves along the channel it drives air into the cylinder(s). It is necessary to close the channel to prevent the air simply being driven around the flywheel; and thus a dipper plate, e.g. a rotating disc 9, is provided, which is moved out of the channel for a certain time during each lobe revolution, to permit the lobe to pass. The disc may be replaced with a pivoted plate 14, Fig. 2. <IMAGE>

Abstract: A gas-measuring unit for a dry gas meter comprises a pair of dished pans 11, 15 having facing flanges 12, 16 secured together with a flexible diaphragm 18 therebetween. To ensure a good seal between the flanges a ribbon 20 of viscous gasket material is applied directly to one of the flanges before the flanges are secured together. One of the flanges may have a groove 13 which is filled with the gasket material, the other flange having a ridge which bites into the material in the groove. Suitable viscous materials are room-temperature vulcanizing silicon rubbers, polysulphides or polyurethanes. <IMAGE>

Title: Railway wagon suspension units
IPC: B61F5/30
Filed: 1979-11-13
Abstract: A frame (1) is mounted over a saddle (2) accommodating an axle journal housing (3) with a load spring suspension system (6) disposed between the frame and the saddle. The saddle bears on the housing through a mounting which includes a rubber block (17) together with the conventional rib (19) and channel (20) structure, the rubber yielding in shear to permit a controlled degree of movement between the saddle and the housing principally restricted to longitudinal motion in the direction of travel of the wagon, and lateral motion by which the saddle pivots on the mounting about the housing. The axle is thus permitted to self steer into tight curves at low speed whilst retaining satisfactory high speed performance, whereas hitherto, the wedges have tended to accommodate longitudinal motion on curves only in a comparatively disjointed fashion by somewhat 'stepwise' slipping and this has been particularly marked at low speeds. <IMAGE>

Abstract: A filter unit for an I.C. engine air intake comprising a tubular body 10 through which air is arranged to be drawn from inlets 18 to outlet 16. Particulate matter carried by the incoming air is thrown outwardly by imparting rotation to the air by means of a fixed stator 20. Such particulate matter is discharged from the unit through one or more flap valves 22 arranged in the wall of the tubular body. The air is then passed through a frusto-conical filter element 28 to outlet 16. Element 28 is of pleated, resin-impregnated cellulose sheet. <IMAGE>

Title: Haymaking machine
IPC: A01D78/12
Filed: 1979-08-24
Abstract: A haymaking machine comprises a rake member rotatable about a vertical axis and supporting a number of carrier arms (9), an outer portion of each being bent (11) or having a crank shape (15). Each outer portion (11, 15) carries tine pairs (48, 49) which are resiliently secured to corresponding shafts (38, 39) whose neighbouring ends are turnably linked to one another by bevel pinions (41, 42, 43) in such a way that a displacement of one pair of tines and the corresponding shaft in one direction will cause a corresponding displacement of the other pair of tines and other shaft in a different and opposite direction. The pinion (43) is resiliently connected to a non-displaceable bracket (47) by an elastomer (46A) which thus resiliently opposes deflection of the pairs of tines (48, 49) from an equilibrium position. In an alternative embodiment pairs of tines are offset forwardly and rearwardly with respect to the intended direction of operative rotation (B) of the rake member and are linked by a connecting rod. <IMAGE>
