Patent GB-362562-A (GB)
Title: Improvements in and relating to electrical ignition apparatus
IPC: F23Q2/28
Filed: 1930-09-26
Abstract: 362,562. Electric pipe &c. lighters. COWX, H. S., 2, Charlotte Street, London. Sept. 26, 1930, No. 28892. [Class 75 (iii).] Comprises in its simplest form, Fig. 1, two live terminals, one being a striking plate movable, as about a pivot 2, and carrying a contact-piece or stud 3, the other 5 fixed and formed as a guide for a striker or torch, which on being laid upon it and moved to the left first touches the stud 3 to close the circuit and then moves the striking plate causing the stud to slip away from the tip of the striker and produce arcing. A wick at the end of the striker or separate ignitable material, such as a taper, is thus ignited. In the completer form shown in Figs. 2 and 3, the movable striking plate 15 is of L-shape, hanging pendulum-wise from a pivot at 14, and forms the armature of an electromagnet, the coil 12 of which is included in the circuit. The spark at 16 is intensified by the coil and the relative movement between the contactpiece and the striker due to the movement of the latter is sharpened by the pull of the magnet. This latter effect may be increased by making the striker of magnetic material, or by making the armature a permanent magnet. A mica washer 4, Fig. 1, may be placed between the contact-piece and the striking plate to prevent arcing on to the latter. The armature 15 is normally retained against its stop 18, by gravity, but a spring which may be of non-magnetic material, may be used as well. The parts shown in Fig. 2 are covered by a casing 19, Fig. 3, and the striker 22 when out of use may be accommodated in a compartment therein, or in a cavity in the electromagnet. An aperture 21 is provided for insertion of the striker. The striker comprises an insulated handle 23 and a metal rod, which may be of high resistance metal to facilitate vaporization of fuel such as paraffin. The end of the striker may be tubular to carry a wick and slotted to facilitate adjustment thereof and provide sparking points. A flange 26 forms a closure for the holder. The circuit may include a switch which is automatically opened when the casing 19 is removed. A number of pairs of live terminals may be used in one apparatus, e.g. the vertical limb of the armature 15 may carry a stud similar to 16 a second conducting plate 10 being arranged adjacent. Further, an auxiliary contact may be provided, normally touching the stud 16 and included in a parallel circuit controlled by a hand switch, so that continuous sparking can be produced (owing to automatic make and break at 16) so long as the switch is closed. The coil 12 may be in series with a number of igniters of the simple form of Fig. 1 arranged at a distance. To facilitate cleaning the armature is readily detachable, 'e.g. by providing the hinge pin with a large head to facilitate withdrawal.

Title: Process for the manufacture of carriers for optical or acoustic purposes
IPC: G11B5/633
Filed: 1959-08-25
Abstract: Film carriers for optical or acoustic purposes (e.g. optical or magnetic sound film carriers) are made by applying at least the carrier substance by electrostatic spraying on to a smooth base and stripping it therefrom when dry.  The carrier substance (e.g. celluloid or acetyl cellulose) may be applied dissolved in a highboiling solvent, excess of solvent being preferred, so as to produce a uniform surface of great smoothness.  A metal strip may be used in known manner as base, electrically-charged for the spray process.  The material to be applied by spraying may be electrostatically charged, e.g. by means of known spray electrodes, before spraying, and the material which is to be coated by subjection to spraying may be passed over a flat electrode or laid on such an electrode and sprayed.  Spraying may be carried out continuously. Details are given of the application of the process to the preparation of materials for use in colour photography.  (see Group XX).

Abstract: 1,087,135. Snap-action switches. PLESSEYU.K. Ltd. July 3, 1964 [July 24, 1963], No. 29345/63. Heading H2B. An on-off switch is actuated by an annular knob H, such as the knob of a potentiometer, and comprises an insulating base plate G carrying two contact pins A, B and a central boss C. A spring D is looped around pin B and is flexed by boss C so as to be urged into contact with pin A. The knob H carries an internal cam E which presents, to the end I of the spring, a slow rise up to an apex E 1  followed by a sharp drop Eg and, in the " off " position, when this cam is fully turned in the direction of the arrow X against a fixed stop F, see Fig. 3 (not shown), the resilience of the spring D causes its end I to move outwards along the surface E 2  so that the spring is itself lifted clear of the contact A. When the knob is there after turned clockwise, the cam carries the end of the spring around with it until it disengages itself and snaps back against the contact A. Returning the knob towards the "off" position causes the cam, towards the end of its travel, to engage the end I of the spring again and cause this to ride inwards up the slow rise of the cam until it reaches and passes the apex and again snaps to the open position.
