Title: Temperature compensated amplifier
IPC: H03F3/45
Filed: 1968-03-22
Abstract: 1,207,242. Transistor amplifying circuits. INTERNATIONAL BUSINESS MACHINES CORP. 22 March, 1968 [7 April, 1967], No. 13914/68. Heading H3T. A transistor amplifier whose small signal gain is proportional to a direct current and varies with temperature is compensated so that the gain is substantially constant over a predetermined temperature range by transistor means to generate the said current to vary with temperature. The input stage of an amplifier is formed by a pair of transistors 1, 2 with difference input terminals 11, 12 and having a common emitter impedance comprising the collector-emitter path of a further transistor 25. The base bias of transistor 25 is determined by the collector potential of a transistor 20, the base of which is directly connected to the collector of a further transistor 15, the base of which is back-coupled to the emitter of transistor 20, so that the collector potential of the latter transistor is largely determined by the baseemitter voltage of transistor 15. Input stage transistor 2 is coupled via capacitor 32 to an integrating stage comprising transistors 36, 39 in Darlington connection with feedback over capacitor 34, followed by an emitter-follower 42 which provides a low-frequency gain limiting feedback over the stage via resistor 46. The output of emitter-follower 42 is passed on to a threshold circuit comprising transistors 52, 56 with common emitter resistor 54 by way of the collector-emitter path of a transistor 47 with earthed base and shunt capacitor 50. In standby condition the emitter of transistor 47 is at a voltage below earth equal to the base-emitter voltage. A positive-going signal is passed by capacitor 50 to the emitter of transistor 47 and so biases it non-conductive, and is passed unchanged to the base of transistor 52. A negative going signal however passes by capacitor 50 to the emitter of transistor 47 which remains conductive, so that no signal reaches the base of transistor 52. Transistors 52, 56 constitute a threshold circuit, transistor 56 which is base-biased from the emitter of transistor 63 normally passing all the current. A positive signal exceeding the predetermined threshold applied to the base of transistor 52 causes reversal of state; the consequential change in collector voltage of transistor, which is linear beyond the threshold point, is passed to a utilization device via an emitter follower 68.

Filed: 1949-05-26
Abstract: 660,492. Centrifugal machines. SILVERSTOLPE, K. O. L. May 26, 1949 [June 15, 1948], No. 14145/49. Class 23 A centrifugal separator for separating particles and the like suspended in liquids comprises a vertical driving shaft carrying a rotor on which holders for test tubes are so mounted that each holder is free to adjust itself substantially in the direction of the resultant of the forces acting upon it at any instant. The rotor 3, Figs. 1 and 4, is of cruciform s h a p e , forming an even number of symmetrically arranged arms on each of which is mounted a test-tube holder 2 by means of gimbal rings 4, 5. The pivots 6, 7 of ring 4 and pivots 8, 9 of ring 5 may each be arranged at 90 degrees to the positions shown, or at an angle less than 90 degrees. In the latter case, the centre lines of the two pairs of pivots advantageously form the same angle, say 45 degrees, with the line connecting the centres of the driving shaft 1 with the holder 2. Movement of the holder 2 is limited by stops 10, 11 and 12, 13 carried by the rings 5 and 4 respectively. The rings 4, 5 may be disposed at different levels. In Figs. 5 and 6, the holder 2 is carried by a ball 14 which engages a socket 15 mounted on or integral with the rotor 3. The required degree of freedom of movement is obtained by flattening the ball and socket at top and bottom, as shown, and providing chamfers 16 and a gap 17 in the socket. To ensure that the holders take up a forwardly slanting position during retardation. they should be heavy and the mountings should be light. Desirably, the pivot means should have rather a tight fit so as to damp the movements of the holder.

Abstract: 1,190,211. Routing self propelled vehicles. BURO PATENT A.G. 30 March, 1967, No. 14644/67. Heading B7N. [Also in Division H4] In a system in which self-propelled trolleys are guided photo-electrically by means of a white or aluminium track defining strip or electromagnetically by means of a ferromagnetic strip or leader cable, means are provided for setting up a destination in control gear on the trolley and for code marking each track divergent point whereby each trolley is routed to its required destination. Lift means may also be controlled in routing a vehicle to e.g. an address on a different floor. Each trolley includes a pair of wheels 5 driven by motor 30 and a steered pair of wheels 6 controlled by unit 22 which is coupled to the coils 18 which co-operate with the track defining strip. In the absence of a strip the trolley is brought to a halt. The trolley also includes a reader 14 including the magnetically operated switches 24 for reading magnetic code markings at track divergent points, halts &c., a reader 15 which co-operates at halts with forward and reverse start magnets and unit 16 including electromagnets 25 which pass coded information from the trolley to trackside apparatus. On approach to a track divergent point, Fig. 4, the position of the track side magnets 33 are read by the reader 14 and if, according to the previously read-in address, the trolley has to diverge at this point, the steering system is actuated to steer the trolley to the track 17<SP>1</SP>. On approaching a halt a reader 40 on the track reads coded information stored in the unit 16 on the trolley to determine if it requires to stop at that halt. If the trolley is required to stop the start bars 37, 36 are de-energized and the gap in the strip brings the trolley to a halt. Bars 36, 37 form the poles of an electromagnet which is polarized in one direction to start the vehicle forward and in the opposite direction to start the vehicle in the reverse direction. The bars co-operate with reader 15 and when the vehicle is not required to stop are polarized in the start forward direction and prevent the vehicle stopping. In approach to a lift, the trolley is stopped and signalling means summon the lift, when the lift is open the trolley is started and enters the lift where it is again halted. Reading means in the lift determine the required floor and when this is reached start means are energized and the trolley leaves the lift.
