Abstract: 864,157. Pneumatic gauging apparatus. SHEFFIELD CORPORATION. March 24, 1959 [April 3, 1958], No. 10205/59. Class 40 (1). [Also in Group XIX] In a pneumatic gauging apparatus in which the flow through a gauging-head is a measure of the dimensions of the gauged object, the pressure supply to the gauge head is maintained constant by automatic adjustment of a feedvalve and the position of this valve used to operate an indicator. Gauging apparatus shown in Fig. 2 comprises gauge head 25 fed via pressure-regulating valve 37, and supply regulator 17, from a supply 16. In operation variations in flow rate through gauge head 25, due to variations in dimensions of test piece 27, result in pressure changes in chamber 12, this change in pressure moves diaphragm 14 connected by pin 34 to valve 37 which moves to tend to stabilize the pressure in chamber 12. Movements of the valve are communicated to the core 44 of differential transformer 40, the secondary windings of which are connected to the indicating and control apparatus 46 and 48. The operating pressure in chamber 12 is controlled by variation of the pressure on the reverse side of diaphragm 14 by means of a valve 51 in the supply line from source 16. A by-pass valve 59 is provided linking the two sides of the diaphragm to enable control of the sensitivity of the device. Valve 56 is provided in parallel with the gauge head to provide zero setting of the equipment.

Abstract: 1302886 Electron beam deflecting systems SIEMENS AG 4 March 1970 [5 March 1969] 10265/70 Heading H1D A corpuscular beam apparatus using two pairs of deflection elements at a common axial location, is provided with two pairs of stigmator elements disposed at 45 degrees to the deflection elements. In Fig. 2 the deflection coils 10-13 are wound on a former 14 of synthetic material or of aluminium. Two sets of stigmator coils 15-18 and 15<SP>1</SP>-18<SP>1</SP> are preferably wound separately before their assembly, although a common former can be used, and the entire arrangement can be potted. If the deflection coils are energized by a current u, stigmatism can be reduced by energising the stigmator coils proportional to u; alternatively it can be eliminated by supplying the coils with a current proportional to u<SP>2</SP>. When two sets of deflection coils are located at displaced axial positions, both may include stigmator coils, but preferably only the one nearest the beam source is provided with stigmator coils. In the latter case the two sets of coils may be energized in series with a current u and with a current proportional to u<SP>2</SP> or u<SP>3</SP>, whereas the stigmator coil is energized with a current proportional to u<SP>2</SP> (Fig. 4, not shown). This allows both stigmatism and distortion to be compensated, the latter being the undesired displacement of the beam from the axis as a result of two equal and opposite deflections. The deflection and/or the stigmator elements may be electrostatic instead of magnetic.

Title: Electric starting means for induction motors, particularly asynchronous motors
IPC: H02K17/30
Filed: 1953-04-20
Abstract: 725,016. Inductances. STANDARD IMPIANTI ELETTRICI E INDUSTRIALI SOC. PER AZIONI., [formerly STANDARD ELECTRIC SOC. PER AZIONI]. April 20, 1953 [April 19, 1952; Oct. 11, 1952; April 4, 1953], No. 10705/53. Class 38 (2). [Also in Group XXXVII] For starting, an induction motor 1 is connected in series with reactors 2a, 2b, 2c, the impedance of which is gradually decreased by increasing the reluctance of the magnetic circuit of the coils. This is effected by gradual increase of the air gap between fixed and movable parts of the magnetic circuit, said increase being controlled in accordance with the difference between the supply potential and the voltagedrop across the reactors. As shown, the displacement between core parts 8, 8a is regulated by auxiliary motors 5, 5a which are on the same shaft and have opposing torques, the motor 5 being energized from the main supply and the other auxiliary motor additionally from the output side of the reactors. When the motor 1 is first energized, the torques of the motors 5, 5a balance, the voltage-drop across the reactor coils decreasing as the motor 1 accelerates so that the motor 5 afterwards overcomes the motor 5a and the shaft 6 is turned to displace the yoke 8. The coupling between the shaft 6 and the yoke 8 comprises a worm shaft 7b driving a wheel 7f which is locked with the yoke 8 when electromagnets 10c are energized to cause pawls 10b to engage teeth 15 in the rim of the wheel. When the yoke 8 reaches the end of its movement at the termination of the starting-period, limit switches de-energize coils 10c and the yoke is returned by the springs 18 to its original position, the pawls 10b slipping over teeth 15. In a modification, Fig. 4 (not shown), the yoke 8 is driven by an auxiliary motor subjected to the supply potential and having a torque which opposes the torque due to the magnetic attraction of the reactance coils. This magnetic attraction torque is initially sufficient to lock the yoke in the minimum reluctance position, and decreases as the motor accelerates, so that the resultant torque applied to the yoke rises with the acceleration of the motor and the impedance of the reactance coils is reduced thereby. The auxiliary motor may be used for returning the yoke to its starting position when the main motor is stopped.
