Title: Windscreen motor switching device
IPC: B60S1/08
Filed: 1970-07-27
Abstract: 1278374 Mechanical switches SWFSPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU GmbH 27 July 1970 [26 July 1969] 36280/70 Heading H1N A windscreen wiper motor is actuated by a switching assembly in the hand grip 51 of an operating lever 52 of a steering column switch. The switching assembly comprises a push-on push-off switch operated by pushing a hand grip cap 54 and a toggle switch actuated by a toggle lever 50. Cap 54 is returned by a spring 33. Secured to cap 54 is the bearing 45 of a star wheel 59, bearing 45 sliding in slots 63 of hand grip 51 when cap 54 is moved axially. Star wheel 59 is asymmetrical, having one long axis and one short axis. Spring contact blades 60 and 70 joined to terminals 15/54 and 31 bear in the off position shown on the longer dimension of star wheel 59 and engage fixed contacts 53a and 31b. In blade 70 is a catch 62. When cap 54 is depressed axially, star wheel 59 moves and engages catch 62 which rotates star wheel 59 so that the shorter dimension of star wheel 59 is then be tween blades 60 and 70. These, because of their pre-stressing, move towards each other, breaking contact 53a and making contact X, breaking contact 31b arid gripping the shorter dimension of star wheel 59 so that it remains in place when cap 54 retracts under the action of spring 33. The circuit is now made from the positive of the battery to terminal 15/54, through blade 60, contact X (Figs. 1 and 2), toggle switch spring blade 68 (Fig. 2), and toggle switch fixed contact 53 to the low speed terminal of the motor. The toggle switch must be in this position after a depression of the cap 54, since cam surface 65 on cap 54 bears on surface 64 of toggle 50 when the cap 54 is depressed to switch it into the position shown in Fig. 2. In this position shoulder 69 of toggle 50 bears on blade 68, toggle 50 being retained in position by spring loaded ball 46 engaging a notch 66. If now toggle 50 is switched, blade 68 changes over to engage with fixed contact 53b and the circuit is made to the high speed terminal of the motor. Depressing cap 54 again, switches the toggle switch back to the low speed position and rotates star wheel 59 to force blades 60 and 70 further apart back to the original off position shown. Circuit diagrams, Figs. 3, 4 (not shown), are provided. In a second embodiment, Figs. 5, 6, 7, 8 (not shown), the operation of the two switches are similar but with only four switch terminals. A separate return switch RS, Figs. 4, 8, to park the wiper is shown diagrammatically.

Title: Improvements in or relating to dobbies or heald machines for weaving looms
IPC: D03C1/10
Filed: 1920-12-29
Abstract: 171,632. Wilmore, A. S. Dec. 29, 1920. Dobbies; pattern surfaces.-In a dobby, the lifting-levers e, Fig. 1, carry swinging balks connected to pairs of upper catch-levers c and pairs of lower catch-levers c', Figs. 1 and 2, whereby the levers e can be so operated as to form a single or double shed. The catch-levers are controlled by feelers f, f<1> arranged in pairs, and are thereby moved out of the path of or remain in position to be engaged by corresponding pairs of upper and lower draw-knives b, b<1>. The feelers f control the lower ones of the lower catch-levers c' by means of arms f<3> and the upper ones of the upper catch-levers c by means of spring-controlled wires g<1>, whilst the feelers f<1> control the upper ones of the lower catch-levers c<1> by means of wires g<2>, and the lower ones of the upper catchlevers c by means of wires g. The wires g<1>, g<2> engage slots f<2> in the feelers f, f<1>, and, when the feelers are operated by ordinary pegs on the pattern chain, these slots prevent the wires g<1>, g' and corresponding catches from being operated so that only one of the catch-levers on a particular balk can engage and be drawn forwards by the draw-knives, and the lifting-levers are only given a single lift. Extra-long pegs are, however, inserted at intervals in the pattern chain, and these move the feelers to such an extent that the wires g', g<2> are operated. Consequently, both an upper and a lower catch-lever on a particular balk can engage and be operated by the draw-knives, the balk being thus drawn forwards at the top and bottom, and the corresponding lifting-lever being given a double lift. The draw-knives are operated by lifting-levers l, m.

[Class 38 (ii).] In a grid-regulated mercury-vapour rectifier installation in which the grids are normally negatively charged but are periodically connected to the positive pole of a D.C. source to render their respective anodes conducting, means operating in response to current or voltage conditions on the D.C. side of the rectifier are provided whereby the moment of connection of the grids to the positive pole is automatically advanced or retarded so as to impart . a compound characteristic to the rectifier. In the arrangement shown, the rectifier 1 fed by a transformer 3 has its grids permanently connected through resistances 13, 14 to the negative pole of a generator 12 and its cathode connected to the centre of a potentiometer 15 connected across the generator. Positive potential impulses are distributed to the grids in turn by a brush 8 rotated synchronously with the supply frequency and co-operating with contact segments 7 connected to the grids. The brush 8 and generator 12 are driven by a synchronous motor 10 the stator windings 10b of which are fed by the supply network whilst the field windings are fed by the generator 12 and are arranged as shown in association with a resistance 17. A regulator 16 actuated by a series coil 16b or a shunt coil 16a associated with the D.C. side of the rectifier co-operates with the resistance 17 in such a manner as to produce a shift in the magnetic axis of the' field of the motor 10 thus advancing or retarding the moment of ignition at the anodes. Alternatively the stator windings 10b or the ring of contact segments 7 may be angularly displaced in response to changes in voltage or current conditions to effect the required regulation.

[Also in Group XXX] Winding cam 2 is secured to winding drum WD so as to make a plurality of turns therewith during a complete wind. Programme cam 1 is driven by said winding drum WD through reduction gearing RG so as to indicate the position of the wind by a turn of less than 360 degrees. Detent 3 is biassed at end 50 against the surface of cam 1. Operation. When the cable has wound off the winding drum to the extent required and the load (e.g. control rod of a nuclear reactor) has been lowered to the position required, indentation 6 on cam 1 has moved round towards the detent 3 so that the end 50 of the detent falls into the indentation. This permits detent 3 to rotate and to cause its end 51 to move towards cam 2. The detent 3 thus engages stop surface 7 of the cam 2 during the next revolution of the latter cam. This stops the unwinding of the cable at the predetermined limit. A second system of detent, indentation and stop surface may be used to limit the wind in the reverse direction.
