Title: An arrangement for remote control of simulators for simulating a fictitious enemy troop and/or activity
IPC: G09B9/00
Filed: 1966-05-11
Abstract: 1,118,015. Teaching warfare; targets. SAAB A.B. 11 May, 1966 [12 May, 1965], No. 20807/66. Headings F3C and F3X. An arrangement for remotely controlling simulators and/or activity in a target area, such as movement of targets and simulating fire and detonations comprises a plurality of audio frequency generators of different frequencies coupled to a transmitter such that the carrier wave thereof is amplitude modulated to provide a number of order signals. A number of receivers are connected to the simulators positioned in the target area and tuned to the carrier wave of the transmitter. Each receiver has connected thereto at least three audio frequency separators which are each tuned to one of the frequencies of the audio frequency generators. Each separator is coupled through a control relay to the actuation circuits of the simulator. The order signals comprise a combination of two of the different frequencies of the audio-frequency generators, the actuation circuits of a simulator being energized only on reception of these two frequencies but not on reception of one or more than two of the frequencies. The targets used in conjunction with this device are of the tilting type and are in the form of men and a tank (Figs. 1, 2, 4, not shown). The simulators or targets are controlled by a training supervisor by means of a push-button control unit (Figs. 3, 7, not shown).

Abstract: 148,964. Ges f³r Nautische Instrumente. May 11, 1916, [Convention date]. Gyroscoyic compasses.-Relates to contacts for use in gyroscopic compasses, relays, and other apparatus subject to vibration including alternating-current apparatus, and consists in providing a damping means between the contact and support to obtain a steady contact and obviate sparking. Two forms of such contacts are shown, the damping device in Fig. 1 consisting of damping cushions, and in Fig. 2 of damped springs. As shown in Fig. 1, a movable contact c oscillates between anvils a, b, damping layers d being interposed between the contacts and the supports. As shown in Fig. 2, the movable contact consists of a ball g oscillating between the bent springs e, the damping being effected by material packed within the helical springs f, h. The damping- material consists of non-resilient material such as felt or wadding, another alternative being small bags of sand. The contacts may form parts of a gyro-compass, the tongue c being attached to the card and the springs c, Fig. 2, being mounted on the follow-up parts. A steady circuit closure and resulting follow-up movement will only take place when a certain pressure is exerted by the contact g on the contact plate a or b. The Specification also states that the dissipated energy during the deformation of the contact damping insertions is extracted from the oscillating system of the gyro-compass, so that its vibrations are also damped.

Contact between relatively rotatable parts of the retarder is limited solely to sliding contact between a rigid annular bearing on one part, e.g. a graphite ring 39 resiliently mounted by washer 40 on a stub 3, and an annular gasket on the other, e.g. a heat conducting ring 41 sealingly fitted to the stator shell. As shown, the rotor shell 2 has pump blades 5 and is splined to stub 3 integral with a plate 21 by a bolt or nut 35 acting through Belleville washers 36; a hard ring 38 is preferably interposed between rotor shell 2 and a shoulder 37 on stub 3. Plate 21 is secured to a pulley on the end of the crank-shaft of the I.C. engine of a road vehicle. Liquid is introduced at 24 to central inlet chamber 9 and pumped from there by blades 5 to the interiors of the shells 2, 7, thence passing by a clearance 11 into the peripheral annular chamber 10. An annular portion of a fixed cover 8 is located near the outer surface of rotor shell 2 to form the constricted annular liquid passage 12. Preferably, as shown, the passage 12 is cylindrical and its axis coincides with that of the rotor; the passage is bounded by radial gaps 15, 16, which permit axial displacement of rotor shell 2 without varying the width of passage 12. Some liquid escapes via a clearance 20 to a chamber 18 surrounding the gasket assembly 19 and passes thence via holes 17 in the rotor to inlet chamber 9, dissipating heat developed at the gasket.
