Title: Method and apparatus for measuring and displaying the  unbalance in a rotor
IPC: G01M1/22
Filed: 1974-10-21
Abstract: 1478157 Measuring rotor unbalance AVERY-DENISON Ltd 21 Oct 1974 [7 Feb 1974] 45421/74 Heading G1N Apparatus for measuring rotor unbalance comprises: an electro-mechanical transducer, and means for combining the transducer signal with a reference signal whose frequency corresponds to the rotor speed; an A-D converter; digital display means for displaying the combined signal in magnitude and sign, and operable in a number of different modes according to the co-ordinate system, units and decimal point position; and means for adjusting the combined signal and for placing the display means in an appropriate mode. Analogue voltage UMI - UMS represent rotor unbalance components in each of two planes as X and Y co-ordinates, and the rotor speed; alternatively the unbalance components may be expressed as polar co-ordinates, according to the setting of a selector switch 27. Each signal in turn, e.g. U M1 , selected at 21, is integrated at 22 for a fixed time determined by a control member 23 connected to a clockpulse generator 26; then the integral is reduced to zero by subtracting from it the integral of a fixed voltage UK, whereupon a comparator 25 signals the control member 23 to transfer a pulse count, accumulated at 24, to a store e.g. 30a as a digital measure of the magnitude of U M1 : a driver 31a feeds a coded magnitude signal, with a further signal representing the sign of U M1 , to a display 32a. The display 32a also receives, from a device 33, calibration information related to machine characteristics, the type of co-ordinate system, and the position of the decimal point. The five signals U M1  - U M5 , processed in time-division multiplex, are displayed on respective displays 32a-32e. Means, Fig. 2 (not shown) sensing when the magnitude of any analogue U M1  - UMS exceeds a predetermined magnitude appropriate to the full range of the display, provides a signal which may warn the operator to switch the range; preferably however the range is switched, and the input signal attenuated as necessary, by automatic means. Further means make appropriate changes when the input signal is insufficient to use one tenth of the selected range. Other means may be provided for cancelling a display if the measured quantity is insignificant on the most sensitive range.

Abstract: 1,126,338. Manufacturing semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 5 Nov., 1965 [19 Dec., 1964], No. 46986/65. Heading H1K. In making semi-conductor devices one face of a semi-conductor wafer is provided with an insulating layer (for example a thermally grown oxide layer) and on this is deposited a supporting stratum (for example of polycrystalline semi - conductor material) to strengthen the wafer in subsequent processing. The free face of the wafer is now etched (or lapped) to a predetermined thickness and a high conductivity monocrystalline or polycrystalline layer of semi-conductor material deposited on the new surface. The supporting stratum is removed, for example with an etch which is stopped by the insulating layer. The original body may contain two layers differing in resistivity-that nearer the insulated surface being an epitaxial layer of relatively high resistivity. The deposited semi-conductor layer of high conductivity may be given a variation of resistivity across its thickness with the lowest resistivity at the free surface and the variation may be continuous or in discrete steps. Further processing is used to form a transistor in which the collector zone includes the high conductivity layer and the contiguous part of the body.

Title: Control system for railroads
IPC: B61L21/06
Filed: 1975-11-18
Abstract: 1532638 Central traffic control GENERAL SIGNAL CORP 18 Nov 1975 [18 Nov 1974] 47472/75 Heading B7H The computer controlled central traffic control system described in Specification 1,452,328, in which track switches and signals at field stations FS1-FSn in a track network are individually set from a control keyboard is modified by the inclusion of an NX routesetting system, whereby a route is automatically set by designating its entry and exit locations, and a facility for automatically setting up vehicle pass movements. The basic central control office layout is substantially the same as that described in the Specification referred to except that the keyboard is extended to incorporate the added facilities. On the keyboard individual control of points and signals is exercised by selection of a numeral kev 10 defining the element followed by operation of a function key 28, etc.; for NX operation the operator designates an entrance location using a selected numerical key 10 followed by key N (70) and then an exit location using another key 10 followed by key X (71), the operator then actuates an execute key 64; for a passing move operation the operator designates the - position, and then operates the-pass and execute keys 73, 64. The railway network is divided into a number of sites each having a number of field stations which in turn include a number of track elements. The site boundary defines the territory displayed to an operator when he calls up a site for display on unit 102 and over which he has control at that time. Where control has to be applied over a number of sites each site is treated individually. Part of the system model of the territory controlled is stored in corresponding site tables in bulk memory 107. For individual control each request results in a command which is checked for validity and then outputs to the field as a control. For NX control the system first decides if a route can be achieved between the two locations, it first attempts to set up a preferred route and if this is not available then an alternative one. If a route cannot be set because elements in the route are in a previously set up route, the route information is stored in a low-queue store until the elements in use are released. Where the system indicates that a route is possible a string of commands are then set up for all the elements in the route, each of which is checked for validity and then used as a control command to the elements in the field. When a control is issued to the field an entry is made in a high queue store and a timer set so that the operator can be warned if a route is not set up in a fixed time period. When a route is set an entry is made in a recall directory and as a train moves over the route the released elements are checked in the low queue store against routes awaiting change in traffic conditions. When a pass is requested this is first turned into the required NX operations each of which, if the route is available, is changed into the required string of commands.
