Title: Improvements in or relating to apparatus for providing a regulated voltage output
IPC: G05F1/42
Filed: 1961-03-15
Abstract: 897,780. Voltage calibration. DAYSTROM Inc. March 15, 1961 [March 24, 1960], No. 9475/61. Class 37. Apparatus for calibrating voltmeters comprises a transformer having tapped secondary windings connected to utilization terminals and a further secondary winding connected to a voltage regulator controlling the voltage applied to the primary winding of the transformer. In the embodiment described, the voltage regulator comprises an auto-transformer 47 and saturable reactor 49, the direct current winding of which is included in the anode circuit of an amplifier tube 52. The output of the auto-transformer 47 is connected to the primary 63 of a transformer 64 having tapped secondaries connected via rotary step-switches to utilization terminals 20 to 31. A further secondary winding 69 is connected to the primary winding of a transformer 74 across which a dynamometer voltmeter of high accuracy is connected. The secondary winding 76 of the transformer 74 is connected across the heater of a diode 81 variation of emission of which is amplified by a tube 88 to vary the emission of a power amplifier 52 whose anode circuit includes the direct current winding of the reactor 49. A stable output voltage is thereby produced, as indicated by the meter 16, the setting of which is effected by coarse and fine potentiometers 17<1>, 18<1>, respectively. The transformer tappings connected to the rotary stepswitches 33, 34, 35 give 4 ranges of outputs from 75 to 1500 volts according to the setting of a selector switch 39. The lowest range (on switch 33) giving taps at 5 volts intervals, switch 34 giving 10 volt intervals and switch 35 giving 20 volt intervals, half digit intermediate intervals being also obtained on switches 34 and 35 by means of switches 37, 38 which in effect add one digit from switches below of lower voltage.

Title: Improvements in or relating to wireless direction finding apparatus
IPC: G01S1/02
Filed: 1923-04-07
Abstract: 195,982. Internationalt Radiotelegraf-& Telefon Compagni ved Wahn÷e & Peters. April 10, 1922, [Convention date]. Bearings, determining; directive signalling.- The bearings of a distant transmitter, whether at sea or in the air, are automatically shown upon an illuminated map at one of two or more fixed beacon stations by apparatus controlled by the moving coil of a Bellini-Tosi or other directional receiving set. The moving search coil r of the aerial system Ra at the main land station controls the movement of a pointer Va pivoted at a point A on the squared map corresponding to the actual location of that station. A second similar pointer Vb is pivoted at a point B on the map corresponding with the position of a second station working in co-operation with the first. The pointer Vb rotated in synchrony with a pointer at the second station, which in turn is controlled by a radiogoniometer coil similar to r. A land line t connects the two stations and allows of the control of the pointer Vb; or the necessary communication between the stations may be by wireless. The point of intersection / of the two pointers indicates the actual position of the ship or aeroplane. The actual "square" position of the point f on the map may be signalled automatically by means of a circuit closed through the square-meshed wire-netting of the maps, and the common point of contact of the arms Va, Vb, in conjunction with a Morsecontact drum or gramophone record associated with each of the map squares. The navigator of the vessel under direction is provided with a similar map, so that the transmission of any given " square " number is sufficient to identify his position. Simultaneously, the contact of the two pointers may light up electric lamps which illuminate, from below, the particular map square concerned.

Title: Multi-position fluid motor mechanism
IPC: F16H63/30
Filed: 1962-03-13
Abstract: 984,195. Change-speed control. WESTINGHOUSE AIR BRAKE CO. March 13, 1962 [March 24, 1961], No. 9620/62. Heading F2D. A change-speed control comprises a plurality of parallel cylinders each containing a fluid operated double - acting differential piston adapted to operate a corresponding gear shift rod to pre-selected definite positions. The fluid motor 1 has three cylinders 5, 6, 7 closed by a common end plate 8 and a combined pressure head and shaft bearing housing 9. The cylinders 5 and 7 each contain a power piston 23 enclosed by a pair of hollow pistons 24, 25 whose inward travel is limited by a snap-ring 20 adjacent which are atmospheric vent holes 21, 22. The cylinder 6 has a power piston 40 and a single hollow piston 41 whose upward movement is limited by a stepped bore in the cylinder adjacent which are vent holes 38, 39. The power pistons 23 have piston rods 30 to which are clamped trunnions 91 engaging forked rockers 87 keyed to shafts 79 carried in the housing 9 and having at their inner ends selector fingers 81, 81a. The piston 40 has a piston-rod 30b to which is clamped a selector finger 103. Pressure from a reservoir 3 passes to a manual selector valve 116, which is connected to the appropriate cylinder ends by pipes 120 ... 125 each of which contains a one-way valve 121a and an adjustable restrictor 121b to allow full charging flow and restricted exhaust flow. The valve 116 is arranged that when the handle 118 is in a neutral position all the cylinders are pressurized at both ends, resulting in the power pistons being held at mid-stroke by the respective hollow pistons. Movement of the handle 118 in the gates 131 into any of the five forward and one reverse positions, results in venting of one end of one cylinder and movement of the respective power piston in that direction to engage the appropriate gear. Movement of the handle back to neutral again pressurizes the respective cylinder end which, due to the differential areas of the power and hollow pistons, causes return of the power piston to the neutral condition.
