Abstract: 1,022,080. Elevated single track railways. LENINGRADSKY GORNY INSTITUTE IMENI G.V. PLEKHANOVA. Dec. 19, 1963, No. 50140/63. Heading B7L. The driving wheels 1 of a locomotive or selfpropelled vehicle which grip the opposite sides of a rail or other traction element 2 are arranged on floating levers 4 pivoted at their ends to links 5, the inner ends of which are connected by yokes 6 traversing the rail 2 and to the vehicle frame through members 7. The arrangement is such that the reaction N o  between the wheels 1 and rail 2 varies with the tractive effort 7. Springs 9 in the members 7 provide an initial reaction when the 'vehicle is at rest. In a first embodiment (Figs. 3 and 4) the links 5 are pivoted to adjustable blocks held in position in the floating levers 4 by bolts 30 and 32 to permit adjustment of the angle between the links 5 and rail 2 and hence the relationship between N o  and T. The locomotive frame is provided with running wheels 11 and an electric motor 12 which drives the traction wheels 1 through worm gearing in casing 13, shafts 17 incorporating pairs of Hooke's joints and gearwheels 20 rigid with the wheels 1. In a second embodiment (Figs. 9, 11) a vehicle body 44 is provided with support wheels 36 and anti-sway wheels 37, respectively, engaging the top 40 and lower flanges 38 of a track 31 and is connected through members 7 with a traction mechanism with support wheels 42 on the yokes 6 and driving wheels 1 engaging the track flanges 41 and driven by motors 45.

Title: Cryoelectric memories.
IPC: G11C11/44
Filed: 1966-11-21
Abstract: 1,162,396. Superconductor memories. RADIO CORPORATION OF AMERICA. 21 Nov., 1966 [22 Nov., 1965], No. 51936/66. Heading H1K. A memory device comprises a superconductor loop for storing persistent current, a superconductor element adjacent said loop to change the inductance of the loop according to whether the element is superconducting or normal, and means for sensing the change in persistent current due to the change in inductance. Fig. 6 shows a loop 54 of hard superconductor (Pb) except for the soft gate portion 56 (Sn) underlying control element 58. A layer, or layers, of soft superconductor constitute a core 60 adjacent a portion of loop 54 and a drive winding 62 lies over this portion in either in-line or transverse configuration. Information is written in by applying currents I x  (in element 58) and I y  (in loop 56) simultaneously (which drives gate portion 56 normal), removing I x  and then I y  to leave a circulating current around loop 54. Non- destructive read out is affected by applying current I k  to drive core 60 normal increasing the inductance of that portion of loop 54 so that the persistent current decreases in magnitude to keep the total flux constant. This change in current develops a voltage at terminal 66 due to the inductance of portion L 2  of loop 54; the inductance of this portion is made higher than the rest of the loop by positioning an aperture 52 in the ground plane under L 2 . A further embodiment is described consisting of an assembly of similar elements to form a 3 x 3 word organized memory (Fig. 8, not shown); Fig. 9 shows a modification in which the loop portion comprises a bridge cell 90, 92, and the core 94 lies between two drive leads 96, 98 (of hard superconductor). Information is applied by passing currents through 96, 98 in the same direction, thus driving 92 normal but not affecting the core 94 while non-destructive read-out is effected by applying currents in 96, 98 in opposite directions to render the core 94 normal without affecting 92. The change in loop current is detected by winding 100 coupled to a part of portion 90 of the loop.

Abstract: 1,253,964. Clamps; turn buttons. ENGLISH ELECTRIC CO. Ltd. 12 Nov., 1968 [15 Nov., 1967], No. 52079/67. Headings E2A and E2B. [Also in Division F2] In a machine a plurality of bearing clamping devices are arranged to retain a shaft bearing in a housing 3 each device including a clamping plate 9 which is rotatable between retaining and release positions relative to said bearing; a clamp-operating member 10 in screw-threaded connection with said plate or with a screw-threaded member rigidly attached said plate, said clamp-operating member being rotatable from outside said housing to turn the plate to said retaining position and to secure the plate in that position; and stop means 18 to cause said plate to rotate with said clamp-operating members into said release position, when the latter member has been unscrewed a predetermined distance. In the construction shown each clamp operating member is a screw which in use is disposed through a bore in the housing 3 with its head abutting one surface of the housing 3 and with the clamping plate disposed on a screw threaded portion of its shank which extends beyond the surface of the housing 3. The clamping plate shown is substantially D-shaped with a threaded hole 15 for engagement by the screw and the stop means 18 is a deformed part of the screw threaded portion of the screw. In a modification however the stop means is a member disposed on the screw threaded portion of the screw. The clamping plate is provided with a lug 14 which by engaging a surface of the housing 3 limits rotation of the clamping plate beyond the retaining position. In a modification the clamping plate instead of being D-shaped is provided with two flanges, and a resilient ring of plastics material or rubber is disposed between the clamping plate and the surface of the housing 3 so that unwanted rotation of the clamping plate from the releasing position is prevented. In a further modification the clamping plate includes a stud 25 having a threaded end portion which is rigidly attached to a member similar to the clamping plate 9 and the means 10 is a nut.

Abstract: 1,098,709. Direct connections. NATIONAL CASH REGISTER CO. Nov. 23, 1966 [Jan. 10, 1966], No. 52363/66. Heading H2E. Permanent electrical connections are made between a plurality of closely spaced conductors mounted in substantially parallel array on the plane surface 11 of a non-conductive or semiconductor member 10, and similarly spaced conductors 36 mounted on a flexible transparent non-conductive strip, by a process employing non-conductive adhesive bonding. The cable member 35 embodying the conductors 36 is covered in its entirety with non- conductive adhesive and brought into close contact under pressure with the member 10, the conductors 36 being placed in alignment with the conductors on the surface 11 of member 10. Adhesive is thus squeezed from between the aligned conductors into the adjacent spaces to form a permanent bond between member 10 and the cable 35. Permanency is established by curing the adhesive by heat treatment. The surfaces of the conductors an unpolished having surface peaks which improve electrical contact between the conductors and valleys in which some adhesive remains thereby improving the strength of the bond formed.
