Title: Improved arrangement for the operation of triggered spark gaps
IPC: H01J17/00
Filed: 1942-07-20
Abstract: 589,129. Impulse generators. BRITISH THOMSON-HOUSTON CO., Ltd., and WILKINSON, K. J. R. July 20, 1942, No. 10120. [Class 40 (v)] Recurrent voltage impulses obtained by charging a capacity or a capacitance network and causing it to discharge into a load by means of a triggered spark gap are initiated by an impulse applied to the trigger electrode of the gap, obtained from the secondary of a peaking transformer whose primary is energized by the charging current or a current proportional thereto, the output of the transformer being used to charge a condenser the energy from which is released to the trigger gap by an auxiliary gap in such a manner that the rate of rise in voltage is of the order 4 Kv per Á second. The Figure shows an' alternating source 1 charging a pulse shaping capacitance network 2 as disclosed in Specification 589,128 through a transformer 3. The network is discharged by a triggered gap 4 as disclosed in Specification 580,003, into a load connected at terminals 15. The primary of a peaking transformer 5 as disclosed in Specification 574,768. [Group XXXV], is connected in series with the source 1 arranged to charge a condenser 7 through a limiting, resistance 6, and is shunted by a load in series with a rectifier 8 so that the secondary peak voltages at alternate waves are insufficient to trigger the gap. Alternatively, the rectifier may be connected across a tertiary winding on the transformer. The discharge circuit of condenser 7 includes inductance 9, condenser 10 and auxiliary and trigger electrodes 11, 12, of the spark gap 4,condenser 10 is shunted by resistance 14. The breakdown of the auxiliary gap 11, 12 induces a voltage between the trigger and main electrodes 12, 13 dependent on the values of condensers 7, 10 and increases the current in the prelimmary ionizing spark. The inductance 9 may form the primary winding of a transformer whose secondary winding feeds a synchronizing voltage to a monitor cathode-ray tube. Specification 578,875 also is referred to.

Title: Improvements in or relating to collapsible telescopic aerials
IPC: H01Q1/08
Filed: 1959-03-24
Abstract: 902,422. Radio receiver aerial arrangements. DORM, W. March 24, 1959 [April 24, 1958], No. 10180/59. Classes 40 (5) and 40 (7). Aerial elements 1, 2, which consist of a number of telescopic units, and are thus adjustable in length, are carried by their outermost tubular units in a mounting which enables the elements to be pushed through the mounting into the interior of the receiver on which the mounting is fixed, as indicated for the element 2, or else drawn out and turned through 90 degrees about an axis perpendicular to the length of the element into an operating position as indicated for the element 1. The mounting is such that limit stops prevent rotation of the aerial elements beyond the two required positions. As shown, the outermost aerial unit is free to slide in a diametric passage in a cylindrical carrier 3 pivoted at 4, 5 in a housing consisting of a U-shaped part 10 and a cover part 7. The part 10 has a threaded projection 11 to which the cover part 7 is attached by means of a screw 12 whose tightness controls the frictional resistance to rotation exerted on the carrier 3. A stop-pin 6 on the carrier projects into an arcuate recess 8 in the cover part 7 and the abutment of the pin against the ends of the recess limits angular movement of the carrier. A plate 13 is attached to the side of the housing and extends upwards to prevent the aerial element being slid back through the carrier except when aligned with the passage through the housing. The two aerial elements together with their carriers and carrier housings are assembled together in a flanged insulating mounting 15 having suitable bores as indicated in Fig. 1. The respective screws 12 project into slots 16, 17 in the mounting and allow limited axial movement of the housings. At one limit as indicated in connection with element 1, the screw 12 is at the top of the slot 15 and the part of the housing containing the carrier projects out of the mounting sufficiently for the aerial element to be turned to its operating position as shown. At the other limit the housing,. after the aerial element has been aligned with the aperture therein, moves into the mounting at the same time as the aerial element is slid through so that a position is reached, as indicated for element 2, where little more than the insulating knob on the extreme end of the element projects. Inward movement of the housing is limited by the projecting part 5 of the carrier pivot making contact with the bottom of a small co-operating slot in the face of the mounting.

Title: Improvements in or relating to means for measuring the eccentricity of rotary shafts
IPC: G01B7/312
Filed: 1949-04-20
Abstract: 666,898. Indicating axial displacement and eccentricity of a rotary shaft. GENERAL ELECTRIC CO., Ltd., BARUGH, J. K., and GARDINER, H. W. B. April 20, 1950. [April 20, 1949] No. 10498/49. Class 40 (i). To measure the radial, axial or oscillatory movement of a rotating shaft, the envelope of an a.c. whose frequency is independent of the speed of rotation of the shaft, is modulated by an electromagnetic means associated with the shaft, the mean amplitude being representative of the axial displacement and the oscillatory movement being represented by variations in the mean amplitude. As shown, the shaft under test 10, Fig. 2, carries a circular disc 14 cooperating with movement detectors 20 ... 23, and 30, 31, each comprising a core carrying an a.c. energized winding, so that the gap between the cores and the disc controls the inductance of the winding. Movement detectors 30, 31 detect axial movement of the shaft, while detectors 20, ... 23 detect vertical and horizontal movements. A motor 51, Fig. 3, drives a generator 50 supplying a.c. to the detectors 20, 22, 23, 21, 30, 31 which are connected in pairs as shown in bridge networks, each of which is normally unbalanced. The output from bridges 20, 22, and 21, 23 is rectified and applied over a smoothing circuit to a meter 69, 90 which thus indicates the average amplitude of the output of the bridges, i.e. the displacement of the shaft as a whole vertically or horizontally consequent upon rotation. The rectified output of the bridges is also applied to transformers 70 and rectified again and applied over amplifiers 72 to meters 73, 91 and recorders 74, 92 to indicate variations due to eccentricity of the shaft. The meters may be ratiometers fed with a.c. from generator 50 to compensate for any variation in the supply. A calibrating voltage may be obtained from an eccentric disc 54 driven by the motor 51 and co-operating with detectors 80, 81. whose output may be switched in place of the bridge outputs. Axial movement results in a variation in the out-of-balance of bridge 30, 31, 93, 94 which after rectification is registered on meter 97 and recorder 98.

A control valve 26 is provided halfway along the exit hose 24. The applicator roller 112 is fed from a wetting device 111 mounted on lazy tongs 15" and urged against the roller by a spring 117 the wetting device having apertures 113 and being fed by tubes 29, 110 from the pipe 24. In a modification of the pressure limiting means the motor may be fixed relative to the base plate and the pressure rollers spring urged against the hose. In one form the rollers are directly urged by springs, in a second they are mounted on spring urged drag links and in a third they are mounted on centrally pivoted levers urged by tension springs. In a modification of the wetting means the lazytongs arrangement may be replaced by a single spring urged pivoted lever. Several shapes of wetting means may be provided which may be curved to fit the applicator roller, straight or curved in the opposite direction. A reciprocable piston can be provided in the main manifold chamber of the wetting means to assist with cleaning. -  In order to promote rotation of the roller even when light pressures are provided a series of cranked spring members 207 act on the surface to cause rotation.
