Title: Improvements in and relating to actuators for electrical switches
Inventor: WHITFIELD ERIC HORNE
IPC: H01H9/16
Filed: 1958-08-25
Abstract: 838,684. Indicators for switches. WELWYN ELECTRICAL LABORATORIES Ltd. Aug. 25, 1958, No. 27246/58. Addition to 836,264. Class 38 (5). A switch 16, as in the parent Specification, has a V-form abutment member 19, the arms of which are alternately engaged by a trigger member 10 to change the condition of the switch upon successive actuations of a knob 8. The trigger 10 has a lug 11 accommodated in a slot 12 in a slidable actuator member 6 and retained against one end 13 of the slot 12 by a spring 24 which thereby also serves to retract the member 6. When knob 8 is pushed the trigger 10, in moving the V-member to its alternate position, swings to one side, the lug 11 being re-seated in slot 12 upon retraction of actuator 6. The knob 8 has a rectangular tunnel in which is slidably located an indicator member 37 of different colour to the knob 8 and/or carrying the word ON while the sill of the tunnel at the inclined corner surface 38 carries the word OFF. The indicator 37 is displaceable by an extension 39 of a slider 28 overlying actuator 6 and having a lug 33 (Fig. 2) engaged by a light spring 30 and a lug 35 (Fig. 1) which can enter a recess 36 in the side of actuator 6. When the switch is operated such that the V-member 19 moves clockwise (Fig. 1) the arm 20 thereof and/or the corner of trigger 10 disengages the lug 35 from recess 36. When actuator 6 is retracted the spring 30 holds the slider 28 stationary and hence the indicator 37 is hidden in the tunnel in knob 8. On the next actuation the V-member 19 is moved anticlockwise, allowing lug 35 to re-enter recess 36 and the slider 28 is moved back with actuator 6, and indicator 37 is thus visible at the edge 38 of knob 8. In a modification, the actuator 6 may be mounted for angular movement on an arm pivoted about one of the bolts or rivets 17, 17a, a suitable knob being provided, and the slider 28 being connected by a lever to an indicator movable from side-to-side within the knob.
Patent GB-1324481-A (GB)
Title: Monostable trigger circuits
IPC: H03K5/04
Filed: 1971-04-19
Abstract: 1324481 Monostable circuit SIEMENS AG 19 April 1971 [23 April 1970] 27257/71 Heading H3T A monostable circuit comprises a bi-stable circuit having an output controlling a timing circuit which produces a ramp signal, the ramp signal being direct-current connected to one input of an amplifier 4 whose output resets the bi-stable, when the ramp voltage equals that of the voltage at the other input of the amplifier, so ending the period of the monostable. In operation, a pulse at A sets bi-stable 16 via monostable trigger 8, 9 which turns off transistor 1. This enables capacitor 2 to be charged via resistor 3 until the ramp voltage across capacitor 2 equals that at the junction of potential divider 6, 5 connected to the other input. The amplifier output then resets the bi-stable 16. Since the voltage across the collector-emitter path of transistor 1 will vary with temperature, the capacitor 2 will start with different voltages. This is compensated by including the collectoremitter path of transistor 7 in the potential divider 5, 6 so that the voltage at the other input of the amplifier varies as that on the capacitor. The monostable trigger 8, 9 has a period determined by the capacitance of the diode 14.

Title: Improvements in methods of packaging and preservation of metal articles and equipment, such as aero-engines
IPC: B65B33/04
Filed: 1948-10-20
Abstract: A sprayable composition for use in the packaging of metal articles to prevent corrosion thereof, (see Group XVII), comprises a web-coat material, a solvent therefor and a solution, in a solvent which is less volatile than the web-coat solvent and for which the web-coat solvent has a sufficient but relatively low tolerance at ordinary temperature, of a vapour phase corrosion inhibitor (V.P.I.), the V.P.I. being per se substantially insoluble in the web-coat solvent, and the web-coat material being substantially insoluble in the V.P.I. solvent.  In the example described, a water-V.P.I. saturated solution is prepared by adding V.P.I. 260 powder (as supplied by Messrs. Shell Chemicals Ltd.) to water at ordinary temperature, and 13 parts by volume of this solution is mixed with 87 parts of methyl ethyl ketone.  The resulting liquid is employed as a solvent for a material such as that sold under the Registered Trade Mark "Cocoon," or described in Example 1 or 3(b) of Specification 608,654, which, when in solution and sprayed from a gun, has the property of forming web-like filaments which may be used to bridge gaps of up to at least 12 inches across, a proportion of approximately 25 per cent of web material to 75 per cent of the V.P.I.-M.E.K. solution being used.  As the web produced by spraying this solution dries, the water-V.P.I. solution separates on to the surface of the web so that, when the water itself dries off, the V.P.I. 260 powder forms a deposit on the surface of the filaments.  Specifications 600,328 and 627,801, [both in Group XVII], also are referred to.

Title: Improvements in or relating to motor vehicles
IPC: G05G7/14
Filed: 1922-10-10
Abstract: 209,204. Seccombe, A. E. S. Oct. 10, 1922. Operating catches.-In motor vehicles of the kind in which the clutch or other controlling member is provided with means for resisting the movement in the directiou for engaging, a construction is provided in which the resistance to engagement increases automatically as the engine speed increases. In one form the rising of the clutch pedal c is resisted by the cup-leathered piston a. of a regulatable dash-pot which forces entrapped air past the screw valve f. The air delivery pipe d' is connected to the induction pipe e in order to oppose a greater resistance to the movement of the air past the valve as the speed of the engine increases, thus increasing the time taken by the clutch to engage. This automatic regulation may also be effected by passing the escaping air through a second valved opening controlled by the movement of the accelerator pedal. In a second construction similar dash-pots are fitted to both the clutch and accelerator pedals, the valve of the accelerator dash-pot being inserted in the pipe d' between the valve f and the induction pipe. This arrangement prevents the engine from being accelerated too much during the period the clutch is engaging.
