Patent GB-2078855-A (GB)
Title: Ignition systems
IPC: F23Q3/00
Filed: 1981-06-29
Abstract: A system for igniting a pilot flame of an industrial gas burner comprises a capacitor C1 which is charged in one sense during operation of a spark generation circuit and in the opposite sense when a flame exists in the vicinity of a spark electrode 13. When a push button is operated, a relay RLI is energised thereby closing its contact RLI-1 to enable repeated triggering of a thyristor SCR1. A capacitor C3 discharges through the primary winding 14 of an ignition coil 11 to supply sparks to the electrode 13 and the voltage at point A becomes positive. On release of the push button, the contacts RLI-1 open, and if a flame exists at the electrode 13 the spark gap acts as a diode so that the voltage at point A becomes negative. This change in polarity is detected and may be displayed or used to actuate controls to automatically operate the burner gas and air valves. <IMAGE>

IPC: E05B67/38
Filed: 1981-07-22
Abstract: A hoop-like element such as a rigid shackle or a flexible chain or cable is closable by a member which includes two relatively movable parts that are secured together in an operative position by means of a plurality of key-operable locks. A shackle (10) (Fig. 1) carries two hinged plates (15, 16) which are adapted to be secured together in overlapping relation across the ends of the shackle by means of several padlocks, the shackles of which pass through aligned pairs of holes (19). Alternatively, the closure member is itself a padlock body assembly (Fig. 5), the body and shackle carrying plates (55, 56) adapted to be secured together by several additional padlocks. Several lock mechanisms (63a-f) may be provided in a common lock body (90) (Fig. 8) to control locking bolts (91) engageable with the shackle (80). <IMAGE>

Title: Artificial eye lens
Inventor: KRASNOV MIKHAIL MIKHAILOVICH
IPC: A61F2/16
Filed: 1981-10-06
Abstract: According to the present invention the artificial eye lens comprises a supporting element made up of two components. The first of these is made as an arc-shaped loop 3 fixed with its ends in the lateral surface of the lens 2 and situated around at least half the length of the lens circumference, being spaced apart from the lens surface a distance equal to the thickness of the iris. The second component of the supporting element is essentially a U-shaped leg 4 which is likewise fixed with its ends in the lens lateral surface and is arranged opposite to the middle portion of the loop 3. The leg 4 is so bent towards the loop as to contact the latter prior to implanting the lens in the posterior eye chamber. (Fig. 3). <IMAGE>

Title: Magnetic recording systems
Inventor: CLARK GORDAN ALBERT
IPC: H03K17/66
Filed: 1982-02-22
Abstract: A magnetic recording system, such as an audio frequency magnetic tape recorder, comprises a pulse width modulator 8-15 which receives the input signal and a magnetic recording transducer 51 which receives the pulse width modulated signal. Thus, the full dynamic range of the recording medium can be utilized to minimise noise and the distortion induced by the transfer characteristic is substantially eliminated, particularly at high signal levels. The modulator is a Schmitt oscillator with amplitude limited by zener diode 15. The oscillator frequency reduces to accommodate lengthening pulse widths of negative polarity without pulse widths being inconveniently short for positive polarity signals. <IMAGE>

Title: Drive arrangement for a fairground ride
Inventor: STEVENS PERRIN
IPC: A63G1/26
Filed: 1983-10-29
Abstract: The arrangement comprises a central drive unit (1, 3) rotatable about a vertical axis (2). At least one radially extending arm (4) is affixed to the central drive unit so as to rotate therewith. The outer end of the arm (4) has a support column (8) for a passenger-carrying car or cars mounted thereon, which column is rotatable about a second vertical axis (9). A rotatable ground engagement member (12) is mounted in bearings (11) on each radial arm. A shaft (14), lying in the same vertical plane as the arm (4) but at an angle thereto, carries a further rotatable member (15) at its radially outer end. The member (15) is journalled to rotate in a bearing (16) on the arm (4) and is guided in a recess. The periphery of the member (15) is in constant frictional engagement with a projecting portion (10) of the column (8). Actuation of the central drive unit causes the arm to rotate in a first direction whilst the frictional engagement between the member (15) and the projecting portion of the column causes the column to rotate in the opposite direction. <IMAGE>

Abstract: 837,548. Lapping tapes on electric conductors. BRITISH INSULATED CALLENDER'S CABLES Ltd. Nov. 27, 1956 [Nov. 28, 1955], No. 34046/55. Class 109 A lapping head for simultaneously applying a number of superimposed layers of tape about a conductor advanced longitudinally through the head from a corresponding number of coils of tape mounted in the head in a group about its axis has for each coil a set of at least two tape-guides fixed against longitudinal movement relative to the head and applicable singly to guide a tape from the coil to the conductor, and a gear drive providing predetermined ratios between the speeds of rotation of the head and of movement of the conductor. Twelve reels 16 of tape are mounted on spindles 14 supported by arms 13 on a sleeve 11 which is driven by bevel gears 19, 18 from a gear box 6 connected to the drive of the capstan which regulates the linear speed of the conductor 1. A bracket 20 on each spindle 14 has three tape guides e.g. 1a, 1b, 1c, in the form of freely rotatable rollers over one of which, depending on the width of tape and diameter of the conductor, the tape passes. The guides on the various arms are spaced axially of the conductor in such a way that they lie on continuous helices or on curves formed by transposing the middle two quarters of a helix (Fig. 5, not shown), and are axially spaced by progressively increasing amounts from the guides on the previous arms while maintaining the same perpendicular distance from the axis of the conductor.

Title: Heating Devices
Inventor: REIK MICHAEL KURT
IPC: H05B3/56
Filed: 1984-03-05
Abstract: A heating device includes a pair of parallel busbars 4 and 6 encased in respective electrically insulating sleeves 8 and 10. A resistance heating wire 12 is coiled around the electrically insulated busbars 4 and 6 and makes contact with the two busbars at regular intervals through cut away portions of the insulation 8 and 10 surrounding the busbars 4 and 6. Discrete lengths of resistance heating wire 12 are thus coupled across the busbars 4 and 6 for energisation therethrough. An electrically insulating sleeve 16 encases the insulated busbars and coiled wire 12. The sleeve 16 is translucent to enable the cut away portions of the insulation surrounding the busbars to be readily identified by eye. When the heating device is cut to a desired length it needs to be severed just beyond a cut away portion to avoid producing a long end section of the device where no heating takes place. <IMAGE>
