Title: Drive mechanism for an up-and-over door
Inventor: PARTSCH ERNEST
IPC: E05F15/681
Filed: 1982-09-21
Abstract: A drive mechanism is described which enables an up-and-over door (3) guided on both sides in two places (6,7) in vertical rails (4) and horizontal rails (5) to be opened and closed by means of just one driving motor (18). In order that the exclusively horizontally acting driving power provided by the driving motor (18) may be converted, when the door (3) is fully open, into a force having a vertical component, a four-pivot linkage (20), comprising links 21, 22, 23, 24 is secured to the door (3). The link (23) is prolonged by an arm (25) (Fig. 4) and articulated by way of a thrust rod (28) to a slide (12). The same is moved by way of a telescopic drive rod (29). Since only a single driving motor (18) is needed to move the door (3) horizontally and vertically, costs are reduced. <IMAGE>

Filed: 1982-10-08
Abstract: A microprocessor controlled currency note validator includes a transport for propelling an inserted note longitudinally past an optical scanning station 36. Infrared and visible color reflectance readings and opacity readings are taken along several longitudinally extending tracks on the note. The microprocessor normalizes the reflectance readings to accommodate for variations in soiling and compares the normalized reflectance readings and the opacity readings against stored acceptance band data, correcting for pattern registration variations if necessary. The length of the note is also checked and a validation signal is provided if the note passes the optical tests and the length test. During the idle cycle, the microprocessor automatically adjusts the optical circuitry to compensate for component drift and dirt buildup. The microprocessor also provides a visual display of any detected malfunctions. <IMAGE>

Title: Integrated antenna device with resistive connection
Inventor: REES HUW DAVID
IPC: H01Q1/38
Filed: 1983-05-04
Abstract: A planar metal antenna (11) mounted on a semiconductor body is connected to a peripheral contact (21) by a connecting link (31) of resistive sheet material. This sheet link (31) is subdivided, by voids or by inclusions of high resistive material, into a number of conductive tracks (57) each of width and spacing of dimension small compared with the width of the antenna. The link (31) thus exhibits an effectively high sheet resistivity at high frequency - ie at a frequency at, or near to, the frequency of antenna resonance and thus affords effective hf isolation between the antenna (11) and the contact (21). At the same time, at dc and at intermediate frequency, a relatively low resistance path is afforded for bias and for extraction of IF signal. An active device such as a diode is integrated in the semiconductor body for switching between antenna portions. <IMAGE>

Title: Flow determination by nuclear magnetic resonance
Inventor: YOUNG IAN ROBERT
IPC: G01F1/716
Filed: 1983-08-31
Abstract: For determining the rate and direction of flow of a liquid in a selected region of a body, NMR is excited preferentially (B1, Gz) in a slice of the body which includes the region and then a magnetic field (-Gz') having a gradient in a direction parallel to the flow of the liquid is applied, this field being effective to cause a phase difference between the resonance for the liquid which is flowing, or has flowed, in the region and the resonance for the rest of the slice; it may be of a magnitude to cause complete rephasing in the latter region only. The free induction decay signal is measured, and the phase difference between the signal from the liquid, and the signal from the rest of the slice (as described, a static volume of water adjacent the body and in the plane of the selected slice provides the latter reference signal) is related to the rate of flow of the liquid through the region. A series of such measurements with different values of t enables other variables (T1, T2, proton density) to be established. <IMAGE>

Patent GB-839565-A (GB)
Abstract: 839,565. Variable wire-wound resistors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 23, 1956 [Oct. 27, 1955], No. 32250/56. Class 37. A variable resistance comprises a resistance element covered with a conductive coating along which a movable contact travels. Figs. 1 and 3a show a variable resistance comprising a non-conductive core 10 supported by an insulating frame 11. Wound around the core is a conventional wire-wound resistor 18 which is coated with a thin layer of high-resistance conductive plastic 16. A sliding wiper 13 moves along support bar 12 and makes contact with the surface of the plastic coating 16 conducting therethrough with the wire-wound element 18. Since the resistance of the plastic 16 between turns 15 is substantially greater than the resistance of each turn 15, for example 10-100 times as great, no short-circuit between turns of the wire-wound element results. The surface of the plastic coating is smooth so that wiper bounce is eliminated and since the temperature coefficient of the wire-wound resistor is low and that of the conductive plastic is high it is possible to obtain a low overall temperature coefficient for the resistance as a whole.
