Patent GB-664361-A (GB)
IPC: G01R19/10
Abstract: 664,361. Electric indicating systems. IGRANIC ELECTRIC CO., Ltd. June 30, 1948. [July 11, 1947] No. 17614/48. Class 40 (i). [Also in Group XXXVI] Apparatus indicating the value of the resultant of plural interrelated electrical quantities comprises a motor generator in which the respective fields are constant and variable by one of the electrical quantities. The motor armature energisation is controlled by another of the quantities and the generator output voltage is proportional to the required ,resultant value. Fig. 1 shows a generator G supplying current I to a series motor M through a series resistor R, wherein the voltage E from potentiometer R<SP>1</SP> across the generator energises the armature of a permanent magnet motor in a motor generator set MG whose generator field is energised by the voltage drop across resistor R. The output voltage Eo of the generator is proportional to EI, the wattage input to motor M. In Fig. 2 (not shown), the MG set generator has a permanent field and its motor field is energised across the series resistor so that Eo is proportional to E/I (and hence to the motor speed) or to R if E = the voltage across it and I = the current therein. In Fig. 3 (not shown) the armature of the MG set motor is energised from constant voltage and its field from the series resistor so that Eo is proportional to <SP>1</SP>/ I , while in Fig. 4 (not shown) the MG set motor armature is fed from the main generator potentiometer, its field from the MG set generator output, and the series resistor is omitted so that Eo is proportional to #E. Specification 512,464 is referred to.

Patent GB-2026333-A (GB)
Title: Sugar centrifuging
IPC: C13B30/06
Filed: 1978-07-25
Abstract: In a sugar centrifuge 3 which separates crystals from liquid by causing the crystals to build up on a screen, 11 through which the liquid passes compacted sugar crystals are removed from the screen after centrifuging by using a very high braking force to stop rotation of the centrifuge very suddenly. The rotation of the screen ceases but the crystals continue to rotate due to their rotational inertia and so detach themselves from the screen. The centrifuge may include one or more apertures 17 in the base 16 of the drum through which the sugar crystals leave the centrifuge. The centrifuge can be rotated at over 1200 r.p.m. and brake means 25 are applied to bring the centrifuge to rest. Plate 13 on driving shaft 7 deflects incoming liquid from pipe 2 radially outwards onto rotating screen 11. <IMAGE>

Title: Electrical plugs
IPC: H01R13/68
Filed: 1978-07-26
Abstract: An electrical plug comprises a base AB in which three pins N, L, E are mounted and a cover AC which is screwed thereto. The bared ends of the conductors are clamped in V- section channels V1, V3, V4 formed in the heads of the pins (or fuse clips P, Q) by wedge-shaped projections W1, W3, W4 provided internally on the cover. As the screw is tightened the cover AC is deformed allowing each projection to be urged independently into the corresponding channel to the extent necessary to exert sufficient clamping pressure. Ducts U1, U2, U3 formed in the base AB define paths of equal length from the point of cable entry to the points of connection and are of a V-shaped section so as temporarily to grip the conductors before the cover can be screwed into place. The cable K is gripped between two opposed flanges X, Y which are formed of flexible and resilient material, mutually inclined in the direction of cable entry, and ribbed transversely of that direction. <IMAGE>

Title: Elastomers and tyres containing them
IPC: C08F236/10
Filed: 1981-02-20
Abstract: Novel copolymers of aromatic vinyl compounds and conjugated diolefins, especially styrene-butadiene copolymers having a vinyl content of at least 30%, have a differential content of the aromatic vinyl compound such that in at least one of its end portions said differential content shows a sharp and substantial increase in the direction of the outer extremity of said end portion. Styrene-butadiene copolymers of special interest are those whose percentage styrene content changes in a portion of not more than 5% of the copolymer chain (as determined by monomer conversion) from a first value to a second value, said second value being at least 25 percentage points greater than said first value; and said portion lies within a terminal 10% portion of the copolymer chain (as determined by monomer conversion). The copolymers may be obtained by appropriate control of the conventional anionic solution copolymerization process. The copolymers of the invention are useful in the tread portion of tyres in that they provide improvement in rolling resistance and/or grip on wet road surfaces.

Title: Clamp arrangements for cooling electrical circuits
IPC: H05K7/14
Filed: 1981-05-15
Abstract: A clamp arrangement for an elongate member 15 extending between two opposed parallel walls 11 includes a multiplicity of slidable elements 35 e.g. balls, which are constrained in a regular staggered configuration within a cage 37. The slidable elements alternately contact a metal strip 61 on the elongate member 15 and an inner surface of an enclosure. A lever pivoted on the elongate member when operated in one direction causes pressure to be exerted on the endmost of the slidable elements 35 which is transmitted to all of the elements, which by producing relative sliding motion therebetween give rise to equal and opposite thrusts on the inner surface of the enclosure and the elongate member pressing the elongate member into close contact with one of the walls. Operating the lever in the opposite direction causes the elongate member to be released. <IMAGE>
