Abstract: 1,006,204. Temperature alarms. WESTING- HOUSE ELECTRIC CORPORATION. Sept. 26, 1963 [Oct. 18, 1962], No. 37882/63. Heading G4N. A bearing failure indicator comprises a stationary surface and a rotatable surface adjacent the bearing which contact each other upon failure of the bearing, and a temperature sensing device which senses the consequent rise in temperature of the stationary surface.

Title: Data storage apparatus
IPC: G06F9/26
Filed: 1966-08-31
Abstract: 1,105,394. Data storage: micro-programme control arrangements. INTERNATIONAL BUSINESS MACHINES CORPORATION. 31 Aug., 1966 [22 Oct., 1965], No. 38738/66. Heading G4A. Certain of the data in a storage register associated with a digital electric data store can be maintained from one storage access cycle to another, means being provided responsive to the state of certain other data positions to select which bytes of a next-to-be addressed word in the store are to be moved into the storage register. In digital electric data-storage apparatus wherein each storage word includes as a portion thereof at least a portion of the address of the next succeeding storage word, storage space is saved due to the fact that when dealing with a sequence of storage words located within adjacent areas of the store the common high order address bits are saved from one storage access cycle to the next. The invention has particular application to micro-programme control using read-only stores. In the arrangement shown (Fig. 1), a read only store (ROS) 22 stores 60-bit storage words which are divided into three instruction words A, B, C of 16, 22 and 22 bits each respectively. One only of these words A, B, or C is transferred during any storage access cycle into ROS register 24 the particular one chosen depending on the configuration of bits 16 and 17 in ROS address register (ROSAR) 28, these bits, originating from the previous micro-instruction, being decoded by word select decoder WD SEL DEC 26 (shown in detail in Fig. 2, not shown). In those cases where word A is selected, bits 10 to 15 of ROS REG 24 remain undisturbed to form the high order part of the next address. USE circuit 34 allows optional (programmed) modification of address bits 18-21 of ROS REG 24 before these bits are applied to ROSAR 29. Bits 1-9, forming the order part of the instruction word, are applied to decode circuits 38 in conventional manner. ROS REG 24 is shown in more detail in Fig. 2 (not shown).

Title: Improved electromagnetic wave transmission device
IPC: H01P3/13
Filed: 1968-08-14
Abstract: 1,235,315. Helical H 01  waveguides. SUMITOMO ELECTRIC INDUSTRIES Ltd. 14 Aug., 1968 [16 Aug., 1967], No. 38910/68. Heading H1W. A helical waveguide for transmission of H 01  circular-electric mode energy comprises a helix of thin insulated copper wire and a wall structure comprising axially alternating zones of different dielectric constant. Thus, the wall impedance of the waveguide varies in the axial direction and can be alternately optimized for attenuation of the unwanted H 11  and H 12  modes. The zones may be formed by helioally wrapping a dielectric tape around the wire helix, the tape having alternating zones of different dielectric constant in its longitudinal direction. Alternatively, the zones may be formed by lossy glass fibre rovings wound alternately tightly and loosely. The same purpose may be achieved by varying the pitch of the winding. In a further alternative method a plurality of tapes are used. In one example, the zones designed to provide maximum attenuation of the H 12  mode are made from graphite fibre material and those designed to provide maximum attenuation of the H 11  mode from copper-plated cotton tape. The zones are surrounded by an iron pipe and the space between the helix and the pipe is evacuated and filled with a thermosetting expoxide resin.

Abstract: 1420853 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 21 Aug 1973 [25 Aug 1972] 39442/73 Heading H4K In an exchange employing a cascade crosspoint switching network of the self-seeking type, e.g. using PNPN diode crosspoints, there is provided a plurality of auxiliary loop circuits which interconnect a line side and a trunk side of said network, such loop circuits being utilized for completing paths through the network between a calling line circuit and a trunk circuit when no direct path is free. In a stored program controlled PABX having duplicate processors, a calling line circuit 16 is connected with a register 60 over a path A by marking the respective network appearances of the two circuits, and a path B is set up between a sender 42 and an outgoing trunk 26. On completion of signalling a direct connection C is attempted between the calling line circuit and trunk but if no such path is available an indirect connection involving path D, auxiliary-loop 64 and path E is set up. For a small percentage of calls where no free auxiliary loop is available, the register 60 may be used as an auxiliary loop. Figs. 3 and 4 (not shown) are block diagrams of an auxiliary loop circuit and a register 60 respectively. The auxiliary loop circuit includes a bi-directional speech amplifier (102) which is transformer coupled to both network appearances of the loop circuit. There is also provided means for providing tones to the calling/called parties, e.g. in the case of Call Waiting, Camp-on-Busy or Assigned Night Answer, and a lamp is provided for giving a visual " loop busy " indication. The register includes a digit registration and storage circuit which may be of the type disclosed in Specification 1,341,468 and converts received digits in two out of seven code into BCD for parallel read out to the central processor. It also acts as a toll restrictor in conjunction with the central processor depending on the class of service of the calling line. A lamp is again provided for giving a visual " register busy " indication. Other circuits having two appearances such as Conference circuits and call transfer circuits are provided, but no details are given.
