Title: Elevator system with object detection means
IPC: B66B13/26
Filed: 1974-12-09
Abstract: 1495393 Control of D.C. motors WESTING- HOUSE ELECTRIC CORP 9 Dec 1974 [18 Dec 1973] 53092/74 Heading H2J [Also in Division E2] An object detection door control mechanism for a lift car door comprises two object detection means either of which is designed to stop door movement when actuated: the first means involves a radiant energy (preferably infra-red) source (60, 64) mounted on the door and directed at a sill portion 74 of the entranceway and a detector means (62, 66) on the door directed at the sill portion; the second means comprises a ribbon switch (KS1, RS2) located along the door edge. As shown centre-opening sliding doors 5, A5 are moved by an electric motor 25 via a lever-and-link mechanism and each door is provided with detection means as described. The surface of the sill portion 74 is designed to scatter the reflected radiation (i.e. rough bronze or aluminium oxide in epoxy resin binder) and the detector means intercept only that radiation scattered parallel to the door edge. Each detector means includes inner (D2, D4) and outer (D1, D3) detectors which respond to radiation from separate T1, T2, T3, T4 transmitters to define inner R70 and outer R68 beams and as the doors near closure limit switches L1, L2 are actuated in turn by cam C1 to render first the outer, then the inner detectors inoperative. The ribbon switches (Fig. 3) comprise spaced conductors 200, 202 set in a plastics or rubber jacket 204 and are connected (Fig. 4, not shown) such that when pressure on a switch causes contact of the conductors, a relay (222) is de-energized to open contacts 224 controlling the safety relay DR in the motor control circuit shown in Fig. 5. A spacer 208 prevents the switches actuating each other in the closed position. The circuit of Fig. 5 is the same as that described and shown in Fig. 4 of copending application 53091/74 Serial No. 1,495,392, except for the omission of the monitor relay (M) and the sources (120, 122) controlled thereby and the replacement of the detector contacts (C102, C104, C114, C116, C112 C112<SP>1</SP>) and the limit switch (108) by the contacts B1 ... B4 of detectors D1 ... D4 and limit switches L1, L2. The latter detectors and switches are similar to those described in copending application 53093/75 Serial No. 1,495,392, whose motor control circuit omits the ribbon switches and the relay 222, 224. The switches L1, L2 operate sequentially during door closing to cut out detectors D1 ... D4 when the doors reach the point where reflection from the sill will be interrupted by the opposite door section. Opening of contacts 224 de-energizes relay DR to provide back-up protection should the detector system fail in a mode permitting the doors to operate. Contacts 224 may be shunted by switch L2 or may (with member 222) be replaced by a solid state relay.
Patent GB-1155859-A (GB)
Title: A Magnetic Device For Changing The Order Of Bits Of A Binary Signal
Inventor: BOBECK ANDREW HENRY
IPC: H04L1/00
Filed: 1966-11-29
Abstract: 1,155,859. Magnetic storage arrangement. WESTERN ELECTRIC CO. Inc. 29 Nov., 1966 [30 Nov., 1965], No. 53382/66. Heading G4C. [Also in Division H3] A magnetic device storing bits in a medium capable of supporting reverse-magnetized domains has input means recording the bits and further means propogating the bits through the medium in a first or second direction so that the bits so stored are in a different order in the medium from that in which they occurred in an input binary signal. As described data is recorded as domain changes in a magnetic wire 11, a write pulse being applied to line 13. A recorded "1" causes a change in magnetization direction as shown, a "0" leaving the magnetization unchanged. During or just preceding the writing of the first bit of the data, a control circuit 27 causes a write pulse from a synchronous write driver to be applied to line 18 to apply a predetermined sequence of domains to wire 12, the sequence of a word of k bits being as indicated in Fig. 1 (which specifically relates to a 3-bit word), lines 21, 23 being read lines controlling the forward and back space shifts. The first data bit 1 is written on wire 11 when the right hand bit R (Fig. 3) on wire 12 recorded by line 18 is read by line 21. The bit R is then erased and the data bits in both wires are shifted left until the lefthand bit M is read by line 23. Bit M is then erased and the data bits in both wires shifted right until the present right-hand bit Q is read by line 21. Bit Q is then erased, the second data bit written on wire 11 and the data in both wires is shifted left until bit N is read by wire 23. The data is shifted right until P is detected and the third data bit written on wire 11. This proceeds until the final bit 0 is detected by line 23 whereon the synchronous write driver is triggered to write another pattern on wire 12 and recommence the operation for the next data word. The final result is an interlacing of the bits of the data word as shown in line t<SP>1</SP> of Fig. 2. The result of the operation is a set of interlaced words and check digits which can be transmitted, the loss of a transmitted word causing only the loss of one bit from a plurality of words, which can be replaced by decoding the check bits. The bits are read out for transmission in the order shown in Fig. 2, line t<SP>1</SP>, when the recorded bits pass under the read line 16 (Fig. 1). For decoding at the receiver, the same pattern is written on wire 12, but a signal on line 23 now causes the incoming data to be written on wire 11 and a signal on line 21 enables the utilization circuit so that the bit passing under line 16 is read out. This causes the signal to be read out as shown in Fig. 2, line t. More advantageously the read line 16 may be situated one position to the left of the write line 13.

Abstract: 1328989 Welding by pressure PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Nov 1970 [13 Nov 1969] 53455/70 Heading B3R [Also in Division H1] An ultrasonic welding method is used to connect the contact areas of an electrical component, e.g. a semi-conductor device, to conductors of a flexible insulating substrate, e.g. synthetic resin or paper. The component body 3 having contact areas 4 is arranged on one pressure member 6 and oriented so that areas 4 be opposite the conductors 2 on substrate 1. The substrate 1 is arranged on a second pressure member 5 which has sharp projections 7. The body 3 and substrate 1 are brought together, pressure applied to members 5 and 6, and an ultrasonic vibration started between the members. During the vibration the projections 7 penetrate partly into the substrate, holding it fixed, and temporarily reinforcing it so as to provide equal pressure to the contact areas. The projections may be an array of pyramids, of a pitch such that at least three are present beneath any contact area, and the projections may partially penetrate the substrate prior to its being brought into contact with the component. The component may be an integrated circuit, film resistor, capacitor, induction coil or a strain gauge.

Abstract: 1480347 Measuring temperature UNITED KINGDOM ATOMIC ENERGY AUTHORITY 27 Nov 1974 [28 Nov 1973] 55280/73 Heading G1A [Also in Division G6]  Temperature of an object is measured by attaching thereto a sensing element consisting of a M÷ssbauer source, i.e. excited atoms of a radioactive element dispersed through a suitable matrix material, in juxta-position with a M÷ssbauer absorber, i.e. unexcited atoms of the daughter element of the excited atoms in the source dispersed in the same matrix material as that of the source, and monitoring the changes in the γ-ray flux from the sensing element. In a particular sensing element, the source comprises <SP>5 7</SP>CO and the absorber <SP>5 7</SP>Fe, both dispersed in a matrix of Pd or Rh. They may be in the form of foils of 0À001" thickness. In the manufacture of such an element a layer of <SP>5 7</SP>Fe is deposited electrolytically on to both sides of a Pd or Rh foil, the foil heated to allow diffusion of the <SP>5 7</SP>Fe into it, a layer of matrix material deposited on to one surface of the first foil, followed by a layer of <SP>5 7</SP>CO and final heating to diffuse the <SP>5 7</SP>CO into that second layer. In the measurement of a turbine blade temperature, the sensing element is mounted on to the rear face thereof and the γ-ray flux issuing from the absorber surface monitored via a window by a proportional counter. The M÷ssbauer fraction f, that fraction of γ-ray emission which passes through the lattice undisturbed by nuclear (lattice) recoil, is dependent on temperature and the intensity of the emitted γ-rays from the sensing element vanes monotonically therewith.
