Patent GB-737090-A (GB)
IPC: F02P15/12
Abstract: 737,090. Ignition systems; stopping. SMITSVONK, N. V. March 31, 1952 [March 31, 1951], No. 8201/52. Classes 7(4) and 7(5). In an engine ignition system having one or more low-tension sparking plugs 19 in which during normal operation the plug or plugs is or are supplied from one or more condensers 16 charged by a magneto comprising primary and secondary windings 1 and 2 respectively, means, such as a vibrator 9, 10 and 11, is provided for separately energising the ignition circuit, the vibrator being connected to the primary winding 1 during the engine starting period and disconnected therefrom after the engine has started. Upon moving a switch arm 3 onto the start contact 5 the primary winding 1 is supplied with pulsed electrical energy from a battery 13 due to the vibratory operation of the contacts 11 actuated by the electromagnet 9. The output from the secondary winding 2 is fed to the condenser 16 via a rectifying system 15, the condenser discharging across the plugs 19 under the control of a distributer 17, 18. The system is rendered inoperative by shortcircuiting the primary winding when the arm 3 is moved onto a stop contact 4. In a modification, another contact is located adjacent the start contact and the switch arm makes contact therewith when it is moved onto the latter so inserting and additional condenser in parallel with the existing condenser or condensers 16. A number of condensers and contacts may be provided so that the primary windings of several magnetos may be simultaneously operated ; two primary windings may be connected in series or parallel and instead of stopping the engine by short circuiting the primary winding a separate stop winding may be used, the field of which opposes the magneto field and prevents normal magneto operation. The starting energy may be obtained from the A.C. mains or by employing an induction coil.

Title: Lubricating Bearings
IPC: F16C33/66
Filed: 1979-06-26
Abstract: The invention provides apparatus having a rolling bearing and means for lubricating the bearing.

Oil falls by gravity down the chamber to a second aperture (37) and through the aperture to bearings (13 and 14). Oil passes through the bearings to second and third fingers (38 and 39) which throw the oil through third and fifth apertures (40 and 42) and into a second chamber (30). Oil falls by gravity down second chamber (30) to a fourth aperture (41) and passes through the fourth aperture back to the reservoir. The invention has particular application to mounting industrial fans.   <IMAGE>
Patent GB-2026223-A (GB)
Title: Electronic tone generator
IPC: G10H7/00
Filed: 1979-07-09
Abstract: An electronic tone or note generator capable of providing improved musical and tone quality and special sound effects by mixing the outputs of a plurality of note-signal-producing circuits is provided. The electronic tone or note generator of the invention is characterized by the use of a primary electronic note circuit for producing a primary note signal which is a portion of a primary melody, and a secondary electronic note circuit for producing a secondary note signal that is musically related to the primary melody. The relationship between signals can be a time lag between the outputs of the two note signal circuits or a small difference in frequency between the signal outputs of the two note circuits. Additionally, each note signal circuit can output alternate notes of a continuing melody such that a note from one circuit may persist while the next note from the second circuit is played. The note signals from the note-producing circuits are shaped and mixed or summed and then applied to an electroacoustic transducer in order to produce audible music of high sound quality. The acoustical frequency of each note and the time between initiation of successive notes are stored in memory units associated with each note-signal-producing circuit. The outputs of high-frequency signal sources are variably divided down to provide the individual note signals and control note timing.

Filed: 1979-08-20
Abstract: The brake comprises a pressure plate 6 arranged to urge brake lining 7 against a disc 10 to be braked by means of springs 8, the brake being released by moving a retraction bolt 4; in order to maintain the release stroke of bolt 4 substantially constant, regardless of the wear of the brake, release movement is transmitted to the bolt 4 by a clamping lever 14 which defines together with a fixed part 24 a wedge-shaped space into which can be drawn an actuating means 30 by means of an electromagnet 23. Upon electromagnet actuation the means 30 is moved to jam the clamping lever 14 upon bolt 4, whereas upon brake actuation upon de-energization of electromagnet 23 the lever 14 is free to be urged against the actuating means 30 by means of a spring 11; and the lever 14 is then slidable on bolt 4 to give automatic new compensation. The actuating means 30 compress rollers 15, 17. In the embodiment of Figures 3, 4 two brake linings (31, 32) are provided and a stirrup spring 34 replaces the compression spring 11 of Figures 1 and 2. <IMAGE>

Title: Method of producing battery separators
IPC: H01M50/477
Filed: 1979-08-29
Abstract: Battery separators are provided with projections 33 on the main relatively flat surface 39 thereof formed from a web. The method of the invention overcomes or mitigates problems of damage to the web and use of organic solvents by a substantial departure from the conventional methods of forming projections as embossed ribs. In the invention, globules, e.g. of a plastics material, are fired at the web and made to stick to it, at least on cooling. Thus they are projected through a gas gap, normally an air gap, to provide substantially rounded projections. Any uneven-ness of the projections can be removed by passing the resultant web through thickness-sizing rollers. <IMAGE>

Title: Telephone systems
IPC: H04M9/02
Filed: 1980-04-30
Abstract: A telephone system with central processor control has telephones including respective data circuits. Each data circuit e.g. a microprocessor scans a respective keypad and stored data relating to the state of the keys thereon. The stored data is forwarded to the central processor on demand from the central processor. The data circuit scans the keys of the keypad and then scans a data input connected to the central processor. On detection of a prefix pulse from the central processor the data circuit makes repeated samples of this data input until detection of a start pulse. Once the start pulse has been detected the data circuit scans the data input at the bit rate. If a key of the keypad changes state more than once between each demand from the central processor, the respective data relating to the subsequent change is not modified by the data circuit.
