Title: Improvements in or relating to electric switches
IPC: B60Q5/00
Filed: 1926-09-17
Abstract: 280,325. Trier, V. A. Sept. 17, 1926. Retractive switches for the steering wheels of vehicles comprise an auxiliary wheel, which carries or constitutes a movable contact, and a ring of rubber which normally insulates the movable contact but allows it to be moved into engagement with a. fixed contact when the auxiliary wheel is rocked. In the form shown in Fig 2, the fixed annular contact D is mounted on the steering post B and the movable annular contact H is carried bv the boss G of the auxiliary wheel, the boss G- being clamped to the outer edge of the rubber ring F the inner portion of which is clamped to the post B. In the form shown in Fig. 4 the auxiliary wheel P constitutes the movable contact and is fastened to the outer edge of the rubber ring N the inner edge of which is fastened to a ring K fixed to the spokes of the steering wheel. The rubber ring may be endless or may consist of a number of segments. The contact rings may also consist of a series of segments, which if desired may be insulated from each other so that different signalling circuits may be closed by pressing different portions of the auxiliary wheel. Two auxiliary wheels may be mounted on the same steering wheel for operating different circuits.

Title: Arrangement including a thyristor rectifier
IPC: H02M7/162
Filed: 1971-04-19
Abstract: 1350095 Automatic control of arc welding A B TUDOR 19 April 1971 [9 March 1970] 23050/71 Heading G3R A thyristor rectifier 2 is arranged to have a rising output characteristic by monitoring the output current at 15 and the output voltage at 16. The current signal from 15 is amplified at 51 (Fig.3) whilst the voltage signal from 16 is subtracted by amplifier 52 from the current signal from 15 after further amplification at 53. The resulting signal from block 29 in Fig.1 is fed to three saw tooth generators 24, 25, 26, synchronised by sine wave signals from the three-phase mains RST. The saw tooth outputs from generators 24, 25, 26 are controlled in such a way that circuit 27 provides six pulses for triggering thyristors 3-8 so as to provide the appropriate output. The slope of the output may be adjusted by variation of the feedback resistor 54. Welding circuits. The system may be employed for arc welding, resistor 54 being adjusted to match the characteristics of the arc. In order to facilitate the burn-off of the cold welding wire at the start of the process the starting voltage may be arranged to be much higher than normal. This is achieved by relay 55 which dis-connects a feedback capacitor 56 across amplifier 52 for a period (40m sec) determined by capacitor 57. (For Figures see next page)

The pawl 21 is carried by a lever 32 pivoted to the pump body 1, and which has a slot 52 engaging with pins 51 on an arm 26 fixed to the piston. Upon the pumping stroke the lever is rocked to the right against its loading spring 37. Grease enters the cylinder through inlets 27 from the pump body which forms a reservoir and is supplied through its inlet 6 with grease preferably under pressure from an accumulator piston. The piston which is loaded by a spring 44 may be actuated either by hand or foot or by a motor. One or more of the pipes may feed secondary distributers which each distribute to further pipe lines. If the outlet pipes 17 are not all required, a device may be fitted to return the distributer to its original position after a predetermined movement. An indicator device shows the position of the distributer. In another embodiment the distributer rotates about an axis perpendicular to the axis of the piston and in this case the pawl is pivoted directly to the piston.

Filed: 1927-09-07
Abstract: 301,567. Bleachers' Association, Ltd., Kershaw, W., Barrett, F. L., and Gaunt, R. Sept. 7, 1927. Yarns &c., treating with liquids, gases, and vapours.-Pattern effects are produced on yarns wholly or partly composed of artificial fibres prepared from cellulose esters, particularly cellulose acetate, by a process which consists in delustring the material and then effecting local regeneration of the lustre by the aid of ethyl lactate. The delustring may be effected by treating the material with dilute solutions of organic or inorganic acids, e.g., acetic or hydrochloric acid, or soaps. The ethyl lactate is preferably printed with a thickening paste on the delustred material in the desired pattern but it may be applied through a stencil or by means of a spray or alternatively a resist may be printed in pattern and the solvent applied uniformly. A delustred or partly delustred fabric may be prepared by weaving wholly or partly with cellulose ester yarns previously delustred. Specifications 259,265 and 269,605 are referred to.

Abstract: 1,200,994. Waveguide filters. STANDARD TELEPHONES & CABLES Ltd. 17 May, 1968, No. 23495/68. Heading H1W. A length of rectangular waveguide having a tuning screw extending into the guide from one of its broad walls, for use, by adjustment of the tuning screw to provide a conjugate capacitive reactance, as an evanescent waveguide filter for an incident H 01  mode of a frequency below cut-off, is at least partially temperature compensated by arranging that the gap between the tip of the tuning screw and the opposite wall of the waveguide is sufficiently small to provide the predominant contribution towards the capacitive reactance, whereby the cross-section of the screw and the gap may be chosen such that the change of capacitive reactance with temperature due to the increase of the gap resulting from thermal expansion compensates for the change of reactance due to the expansion of the guide alone, and therefore maintains the conjugate match condition of the section substantially independent of temperature. As shown, the evanescent mode cavity 3 couples the two propagating guides 1 and 2, and has a tuning screw 4 disposed in the centre line 5 of one broad wall and providing a gap d with the other broad wall. In modified arrangements, the screw is off-set from the centre line 5 (Fig. 2, not shown), or two screwsa main tuning screw off-set from the centre line and a fine tuning screw in the centre line-are employed. To avoid inconveniently small values of the gap d, the tuning screw may be of material of lower thermal expansion coefficient than that of the guide, e.g. a silver-plated iron screw in a copper guide.
