IPC: G06F3/06
Filed: 1954-11-17
Abstract: 804,071. Electric digital-data-storage apparatus. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Nov. 14, 1955 [Nov. 17, 1954], No. 33336/54. Class 106 (1). [Also in Group XL (c)] A sampling arrangement produces a pulse train which changes from a pulse to a no-pulse condition or vice versa in dependence upon the amplitude of an input waveform at the sampling instants. The arrangement has particular application in connection with the storage of information in the form of binary digits and particularly when the store is of the magnetic drum type. The input waveform to be sampled is derived from the drum and is as shown at A in Fig. 1, this is applied to the centre tap P, Fig. 5, of a balanced transformer so that the waveform A is applied to the trigger side of a bistable trigger circuit TC and the inverse waveform B, Fig. 1, is applied to the reset side. A series of regularly recurring narrow strobe pulses C, Fig. 1, determine the instants of sampling and are applied at terminal Z of a coincidence circuit to which the input waveform A is also applied. Thus a waveform as shown at D, Fig. 1, is generated at the output A of the coincidence circuit on the trigger side of the circuit TC and a waveform as shown at E, Fig. 1, is generated on the reset side at point B of the trigger circuit so that the output at lead X of the trigger circuit is shown at F, Fig. 1, and the output at Y is the inverse of this as shown at G, Fig. 1. The input waveform derived from the magnetic drum may have other characteristics, Figs. 2 and 3 (not shown). In a modification, Figs. 4 and 6 (not shown), a short pulse only is produced during the sampling period. Specification 801,681 is referred to.

Title: Apparatus for determining the position of an object
IPC: G01S1/08
Filed: 1974-07-29
Abstract: 1465134 Determining object position inductively POLHEMUS NAVIGATION SCIENCES Inc 29 July 1974 [30 July 1973] 33421/74 Heading H4U To determine a parameter of an object relative to a co-ordinate frame at least two field generators at the origin of the frame are arranged to produce field components along the co-ordinate axes and are supplied with driving signals which are varied to produce a resultant field which nutates about a sector coinciding with the mean direction of the field. The resultant field is sensed at the object. A signal representing the parameter is derived from the sensed field. (Nutation includes oscillation). The method is used in an object tracking system in which a D.C. and two primary A.C.1, A.C.2 reference signals 142, 146, 144 are generated and applied to orthogonally arranged coils 64, 66, 158 via resolvers 220, 222. The application of the signals to the orthogonal coils produces a magnetic field nutating about a main direction whose position can be controlled by the resolver, which enables the reference frame established by the axes of the orthogonal coils to be transformed. At the receiver on the tracked object, the nutating field is detected by orthogonally arranged sensor coils whose outputs are passed via two co-ordinate transformation circuits 250, 252 to sense circuits 26. The first transformation circuit 250 resolves the reference signal mix attributable to the orientation of the object while the second 252 resolves that part of the mix attributable to the mean field direction. The signals sensed by the sense circuits 26 which receive the original D.C., A.C.1, A.C.2 signals as references should correspond to the original reference signals D.C., A.C.1, A.C.2, e.g. the signal on the 194 should be a pure D.C. Similarly, the signals on lines 192, 196 should be A.C. at the nutation frequency. If they are not, then a pointing error exist. The error signals detected by the sense circuits 26 are used to correct signals representing approximations to the required orientation and translation stored in unit 100. These signals are fed to the various resolves in the system such that the errors detected by the sense circuits are reduced to zero, at which time the circuits 100 deliver signals representing the correct angular orientation and direction of the object.

An orbital finishing machine has an opentopped tub 1 comprising a generally cylindrical steel shell 2 with vertical flanges 2a. A flat steel end piece 3 is welded to one end of the shell. Welded to the other end of the shell is a steel end piece 4 having a discharge opening 4a, a door 5 and a discharge shoot 6. At the bottom of the tub is a drain assembly 7. A steel cradle 8 welded to the tub comprises steadying pieces 8a, one or more longitudinal members 8b and two longitudinal angles 8c. The latter are welded to uprights 9 connected through rubber-in-shear mounting assemblies 11 to stationary uprights 10. Eccentric shafting 12 is driven by a pulley 13 to impart vibration. A shield 16, consisting of a backing 17 of 16-gauge impact and abrasion resistant sheet steel to which is permanently bonded a thick layer 18 of high performance rubber, is a loose fit in the shell 2 and is of undulating shape, resulting in spaces 19 between it and the shell 2. The top portions of the shield 16 are clamped to the shell by two longitudinal strips 22 secured by bolts 23 and nuts 24. On each of the two opposite sides of the shell 2 a series of mounting pieces 26 is welded to the outer surface of the shell, each piece receiving the threaded hollow stem of an elbow fitting 27. A conduit serving as a common source of cooling water communicates with inlets 28 in the fittings 27. The water passes through openings 29 in the shell into the spaces 19. At one end is a shield 30, consisting of a metal backing sheet 31 to which is bonded a layer 32 of rubber, and having vertical ridges 33 behind which are vertical spaces acting as water courses. Spacers 34 are located between the shield and the end piece 3; bolts 35 passing through the top spacer hold the shield 30 in place so that it can hang more or less loosely. Cooling water entering through mounting pieces 38 and fittings 39 tends to fill voids 37 behind the shield 30 which act as headers. At the bottom of the tub the shield 16 has a group of small openings 40 overlying a large drain opening immediately above the drain assembly 7, so that any water entering through the end piece 3 which finds its way into the shield 16 can escape. Metal shields without rubber linings may be used. The ridges may extend parallel to the major axis of the tub, annular headers being provided at the ends of the vessel.

Classes 83 (2) and 83 (4). A method of increasing the strength of drawn wire, e.g. of tungsten or molybdenum, consists in subjecting to torsion the ingot from which the wire is to be drawn while said ingot is in a heated plastic condition, mechanically working the ingot to elongate the crystal structure and then drawing the ingot into wire. In an embodiment a tungsten rod having a fibroid structure of approximately 0.140 inch diameter is heated in an electric furnace to 1500‹ C. in a non-oxidizing atmosphere leaving the ends of the rod exposed to enable one end to be secured against rotation while the other end is gripped in a chuck which is rotated upwards of 80 complete rotations. The treated rod is subsequently swaged and drawn, under standard conditions, to wire of 0.007 inch diameter by repeatedly passing the rod through dies of successively reduced cross-sectional area and then recrystallized by heating.
