Abstract: 1,109,52. Ignition systems. ROTAX Ltd. Jan.7, 1966 [Feb.10, 1965], No.5729/65. Heading F1B. In a spark ignition system, at predetermined intervals the spark produced at the spark gap 18 is of higher energy than the remaining sparks. As shown pulses of current pass through the diode 15 and charge the capacitor 17 through the spark gap 18. After a predetermined number of pulses, however, the voltage across the capacitor 17 reaches the breakdown voltage of the control gap 16 which conducts to cause the capacitor to discharge through the spark gap 18 and produce a spark of higher energy. In a modification a double spark gap associated with resistors is employed. In another modification there are two capacitors separately charged and each associated with a spark gap and one gap is arranged to breakdown more frequently than the other. Alternatively the capacitors could be charged by the same source. A semi-conductor plug or multi-gap plug may be used.

Abstract: 1,225,476. Winding machines; measuring apparatus. OWENS-CORNING FIBERGLAS CORP. 6 May, 1969 [22 May, 1968], No. 22990/69. Headings D1F and D1J. Filamentary material, especially strands or bundles of glass fibre 122c, is fed to a winding machine 45 by a driven roller 240 which advances the strand whilst tension is maintained therein, but ceases to do so upon loss of tension. The surface of the roller 240 is of polyurethane or other resinous material. If tension is lost, the strand slips on the roller surface, and an arm 76" drops operating a micro-switch 98" to stop the winding motor. A plurality of winding machines 45 may be fed by one roller, or by individual rollers having a common drive (Figs. 3 to 6, not shown). In either case loss of tension in one strand interrupts only the corresponding winding head. A projection on the roller spindle, passing through an electromagnetic field produces pulses to operate counters on each winder to indicate the length of yarn wound. Operation of micro-switch 98" also breaks the corresponding counter circuit, so that pulses are not counted while the strand is slipping over the roller 240. The length of contact between the strand 122c and its roller 240 may be adjusted by movement of idler rollers 230, 232. The strand may be impregnated or coated with an elastomer and passed through a drying oven 144" before advancing to the feed roller 240.

Abstract: 1,226,153. Electrolytic etching of semiconductor material. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb.22, 1968 [Feb.25, 1967], No.8638/68. Heading C7B. [Also in Division H1| The conditions during the removal by electrolytic etching of a relatively low resistivity n-type semi-conductor body from a thin relatively high resistivity n-type epitaxial layer grown thereon are so arranged that etching substantially or completely stops at locations at which the relatively high resistivity material is exposed. Germanium and silicon are suitable semi-conductors. When etching silicon with fluoride etchants at a suitable voltage a passivating film is formed on the high resistivity material as it is exposed. As shown a stirred polythene bath 36 contains an etchant consisting of 1 vol. part of 50 wt % aqueous HF and 10 vol. parts H 2 O and has a 4 cm square platinum gauze electrode 40. (An alternative etchant consists of 1 vol. part 50 wt % aqueous HF and 16 parts of a solution of 200g NH 4 F in 100g H 2 O.) A silicon disc 1 having an n-type low resistivity body and a thin high resistivity n-type epitaxial layer is bonded by its epitaxial layer using Canada balsom or colophony to a paraffin masked glass plate and the assembly held by a platinum connector 31 and attached polymethylmethacrylate clip 30. Etching removes the low resistivity body to leave the thin layer. To ensure that parts remote from the connection are not left unetched, the assembly is lowered slowly into the bath at the commencement of etching to thin remote parts first. Etching is carried out in the dark. The thin epitaxial layer may contain semi-conductor components at the face remote from the etchant, and may be formed throughout its depth with a grid of low resistivity n-type material so that it is separated by the etching process into a plurality of small wafers. Other support structures than the glass plate may be used and may form permanent parts of the finished semi-conductor devices.

Abstract: 1,228,189. Projectile firing game. KOHNER BROS. Inc. 24 Sept., 1968 [25 Oct., 1967], No. 45417/68. Heading A6H. A projectile firing game apparatus comprises a target grid 22, projectiles 26 and projectile launchers 24 optionally incorporating a scorer. The target grid comprises a horizontal projectile receiving partition 34 in which rows and columns of upwardly facing downwardly convergent seats 36 of square inverted pyramid truncated by a circular opening 40 form are arranged, the boundaries of the seats all being in the same horizontal plane and the array being subdivided into juxtaposed sections of the same colour for receipt of projectiles of the same colour. Each projectile 26 is a hollow cone of flexible resilient plastic, the interior of the projectile adjacent the nose 48 having a cylindrical well 54, which may have lugs 56 on the open end, into which well a metal ball 52 is forced fitted thus weighting the projectile. The broader open end of the projectile may have an annular stabilising flange (50) extending radially outwards. The projectile launcher 24 comprises a base 58 a lauching lever 60 and a scoring marker 62. The launching lever 60 pivots about the pins 88 at one end of the base. The projectile 26 is lanched by placing it on the dome 76 and pressing the shank 74 of the lever against the tension of the spring 64, and releasing the lever 60. The spring decompresses until the lever comes into contact with the top of the slot 70 in the housing 68 fixed to the base thus launching the projectile. For ease of assembly the lever 60 is bifurcated at its pivoted end so that the fingers 82 so formed can be squeezed together and the pins 88 of the lever assembled in the slots 72 on the base. The housing 68 may have two protuberances 90 depending between the bifurcated lever 60 to prevent easy disassembly of the launcher. The scoring marker 62 is a device which interlocks distally with the base 58, so that it slides along the gap 102 extending the width of the base, thus indicating the score of a player at the window 118 on the scale 100. In a game, up to four players are supplied with a launcher 24 of a colour indicated at 66 and several projectiles 26 of the same colour and they attempt to launch the projectiles into the quadrant of the target grid of the same colour.

Abstract: 1,234,400. 234, 400. Treating I. C. engine exhaust; induction passages; valve gear. STANDARDTRIUMPH MOTOR CO. Ltd. June 19, 1968 [Dec. 22, 1967], No.58383/67. Heading F1B. Means for adding air to the combustion products within an I. C. engine cylinder for further oxidation of the combustion products comprise a source of compressed air, a duct along which the compressed air passes, and control means for adding air from the duct to the combustion products in the cylinder for a period starting not earlier than the opening point of the exhaust valve, the control means also being arranged for adding air from the duct to the products of combustion in an exhaust passage leading from the cylinder downstream of the exhaust valve for a period starting at or about the same time as the exhaust valve opens and continuing until or about the same time as the exhaust valve closes, whereby further oxidation of the combustion products is enhanced. An auxiliary poppet valve 30 which, as shown, may be operated by the rocker 21 that operates the exhaust valve 18, is opened at about the same time as the exhaust valve so as to admit compressed air from a duct 39 to a pipe 45. The air flows through holes 46 into the exhaust passage 16 to mix with the exhaust gases and also flows through a bore 49 into the cylinder 17 to blow the combustion products out of the cylinder while mixing with them. The air provides further oxidation of the obnoxious constituents of the combustion products. The bore 49 is uncovered by the piston crown (or the top piston ring) at about 90 degrees before bottom dead centre so that it is already open when the air valve 30 and exhaust valve 18 open (at about 60 degrees before bottom dead centre), but is covered again at about 90 degrees after bottom dead centre. Thereafter, flow through the bore 49 ceases and the consequent rise in pressure in the pipe 45 causes an increased flow through the holes 46. To compensate for the discontinuous air flow, an air reservoir may be provided. Air may be fed to the cylinder 17 and exhaust passage 16 through separate pipes or may be fed to the cylinder only. The air valve 30 may be operated by a separate cam, which may be on a separate cam-shaft.
