Filed: 1971-11-26
Abstract: 1374100 Determining train location SUMITOMO ELECTRIC INDUSTRIES Ltd 26 Nov 1971 [26 Nov 1970] 55102/71 Heading B7N [Also in Divisions H4 and G4] To determine the location of a body moving along a predetermined path, pairs of conductors 14 1 , 14 2 , 14 3  ... laid in parallel along the path are inductively coupled with respective antennae 15 1 , 15 2 , 15 3  ... or a common antenna, carried on the moving body, the coupling between a conductor pair and its respective antenna or the common antenna varying periodically as the body moves along the path. By transmitting the same frequency from the separate antennae to each conductor pair or vice versa, or a unique frequency from each of the conductor pairs to the common antenna, a coded combination of signals is received either by the moving body, or a control station 16, indicating the position of the body along the predetermined path. Each conductor pair has sections where the two conductors are superimposed thereby reducing the inductive coupling with its respective, or the common, antenna, the length of such sections varying from conductor pair to conductor pair according to the power of 2, whereby the received signal is a binary signal. The two conductors of a pair cross over after each superimposed section to reduce interference between the coupling sections.

Abstract: 1,253,965. Friction clutches. DYNAIR Ltd. 20 Dec., 1968 [4 Dec., 1967], No. 55131/67. Headings F2C and F2L.  A clutch for a cooling fan is engaged by compressed air which is admitted to a chamber 13 through an orifice 17 and moves to the left a main-rotary annular piston 14. This motion is transferred through a bearing 18 to a sleeve 19, fast with an input shaft 12, and to a clutch plate 22. A surface 23 of clutch plate 22 compresses a radially split annular friction element 37 between members 33 and 35, thus transmitting the drive through a member 30 to an output shaft, not shown. A spring 24 disengages the clutch. The clutch is operated in response to the temperature of the cooling water in a vehicle radiator, Fig. 2, (not shown), illustrates a modification in which the clutch is engaged by bolts 45 if the compressed air supply fails.

Abstract: 1451084 Semiconductor integrated memories HITACHI Ltd 7 Dec 1973 [8 Dec 1972] 56770/73 Heading H1K An integrated semiconductor memory stage (Fig. 1) a plurality of which may be contained in a single substrate comprises a P-type substrate 1b a N<SP>+</SP> type layer 10a buried therein, a P-layer 2b epitaxially grown thereon with low impurity concentration, and a N<SP>+</SP> layer formed in layer 2b by e.g. in-diffusion of N<SP>+</SP> impurity. Inverse transistors T 1 , T 2  have emitters constituted by exposed portions of N<SP>+</SP> regions 3b, bases constituted by P- regions 4n, and collectors constituted by N<SP>+</SP> regions 5b; the buried portion of 3b interconnecting the transistor emitters. (Fig. 3a). Transistors T 3 , T 4  comprise a N<SP>+</SP> collector region 6b, P- base regions 7b, and N<SP>+</SP> emitter regions 8b wherein the layer 6b interconnects the collectors. (Fig. 3b). N- channel MISFETS T5, T6 (Fig. 3a) are formed in N-type region 12b with drains constituted by collector regions 6b of transistors T 3 , T 4  and gates 11b being formed on insulant layer 11b. Sources are constituted by N<SP>+</SP> regions 9b in P- region 2b and the collectors of T 3 , T 4  and drains of T 5 , T 6  are interconnected. The emitters of T 1 , T 2  and the collectors and drains of T 3 , T 4 ; T 5 , T 6  are interconnected within the substrates and the remaining interconnections are established on the substrate surface to establish the circuit of Fig. 1. Since the collectors of inverse transistors T 1 , T 2  are connected by N<SP>+</SP> region the bases are constituted by low impurity P- regions, and the emitters by an N<SP>+</SP> layer; injection carrier efficiency and current gain are enhanced. The transistors T 1 , T 2 , T 3 , T 4  are NPN type in the P- layer and are thus selfisolating from the remaining elements respectively by their emitter and collector regions, and the interconnections within the substrate are in regions of high impurity concentration and low distributed resistance so that plural cells may be connected to word and power lines respectively. The depletion MISFET leads provide stable loading, high speed operation, and lower power consumption.

Abstract: 1362976 Bearings LIDKOPINGS MEKANISKA VERKSTADS AB 8 Dec 1971 [14 Dec 1970] 56999/71 Heading F2A [Also in Division B3]  A fluid bearing comprises two relatively movable elements and means for supplying fluid to the bearing which include a throttle formed by adjacent surfaces of the elements, the arrangement being such that variation in the separation of the opposed surfaces of the elements varies the flow of fluid to the surfaces. As described the bearing constitutes the slide of a machine tool. One bearing element 52 is secured to a reciprocating table 48, and is located in a groove 54 in the support 55, which forms the other bearing element. Pockets 4, 5, 6 are formed in the surface of one of the elements to which fluid is fed under pressure to form with the other element a fluid bearing. Each pocket has a corresponding pocket formed in the surface of the same element which is remote from the surface of the first pocket.

Solid propellant is extruded using a machine comprising a hollow screw impeller 1 with at least a four-start screw-thread 16, the impeller being axially movable rearwardly against the pressure of fluid in a chamber 5 when above normal working pressures occur, with operation of a limit switch 10 to stop the machine if these pressures persist. Chamber 5 is defined by an end plate 21 of splinterproof housing 14 and a piston 20 attached to impeller 1, the hydraulic system comprising an excess pressure valve 7, pump 6, by-pass 8 and reservoir 23. The downstream end of impeller 1 is closed by a cap 11, which in the event of ignition of the propellant in die 3 bursts and allows escape of gases through the impeller, and furthermore is eccentric to form a roller-type kneader. Ignition in or around screw-thread 16 causes rupture of a relatively thin wall 13, gases escaping via ports 15 in casing 14. A system of springs may replace the hydraulic system.
