Title: Starting device for internal combustion engines with a motor dynamo and a planet gear in connection with an internally toothed wheel
IPC: F02N99/00
Filed: 1921-12-28
Abstract: 173,755. Neumeyer Akt.-Ges., F. Jan. 10, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Turning-gear.-In an electric starter in which the starting-motor drives the engine shaft through planetary gearing and is driven at engine speed as a generator when the engine is running, an interrupter and a distributor for battery ignition are driven from a part of the planetary gearing rotating at engine speed. In the form shown, a pinion 2 on the hollow armature shaft 1 engages planet wheels 3, which are carried by a freely rotatable disc 7 and engage an internally-toothed gear 5 connected by a free-wheel coupling 22 to a toothed ring 20 in engagement with the pinion 2. The disc 7 is integral with a central pinion 8 engaging a second set of planet wheels 9, which also engage the gear 5. The wheels 9 are carried by a disc 11 integral with a sleeve 18 rotatable on the shaft 1 and carrying a pinion 14 on a sprocket-wheel geared to the engine shaft. The interrupter and distributor are driven from the sleeve 13, preferably through a coupling 56 and a shaft 53 extending through the hollow shaft 1 to the rear of the apparatus. The interrupter may however be mounted on the front of the apparatus and driven directly by a pinion on the sleeve 13. The internally-toothed gear 5 is held at starting by spring-pressed pawls 28 in engagement with teeth 25 on the back of the gear, and the pinion 14 is then driven from the shaft 1 through the planetary train. The pawls have conical recesses 34 for engagement by conepointed pins 36, Fig. 3, but initially the pins are withdrawn by solenoids 45 supplied with current at the same time as the starting-motor. When the engine starts, current is cut off from the solenoids and the pawls are withdrawn by the action of the pins, which are forced into the recesses 34 by spring-pressed bars 42 or by coil springs. The planetary gearing then rotates as a whole and the motor is driven as a generator at engine speed.

Title: Pyrolytic silicon nitride
IPC: C04B35/584
Filed: 1963-09-05
Abstract: Non-porous, alkali-stable silicon nitride is prepared by contacting a hot surface at a temperature of 1200 DEG  C. to 1900 DEG  C. with a gaseous mixture of a silicon halide and anhydrous ammonia. The hot surface, resistant to thermal decomposition at the temperatures employed, may be alumina, graphite, boron nitride or silicon nitride, and the boron nitride may be that obtained from boron trifluoride and ammonia by a process similar to that of the present invention.  The mixture of the silicon halide, preferably SiF4, and ammonia, has a combined partial pressure of less than 300 mm. of mercury and preferably contains 50-85 mol. per cent ammonia.  The components are introduced separately and simultaneously into a chamber containing or forming the hot surface. Alternatively, a carrier gas, e.g. N2, neon, krypton and argon may be present and the reaction carried out at pressures up to atmospheric and above.  After deposition of Si3N4, the forming hot surface may be removed by burning, volatilization or dissolution.  The product is characterized by having a density close to the theoretical density calculated from crystallographic data.

Title: Improvements in the colouration of textile materials
Inventor: OLPIN HENRY CHARLES
IPC: D06P5/20
Filed: 1954-12-03
Abstract: Dyes and azo dye components are incorporated in textile materials of cellulose acetate of acetyl value at least 59 per cent, calculated as acetic acid, by applying the dye or dye component in a hot aqueous medium at a temperature exceeding 100 DEG  C.  The textiles may be treated with a hot aqueous bath under pressure or they may be padded with the aqueous liquor and then treated with saturated steam under pressure.  Suitable dyestuffs, many examples of which are given, are disperse acetate dyes, unreduced or free leuco compounds of vat dyes and water-insoluble or slightly soluble metallized dyes.  Diazo and coupling components may also be applied together or separately, diazotization and coupling being effected on the fibre, and in some cases when the components are applied together, the material may first be treated at a temperature above 100 DEG  C. and then at a lower temperature.  The process is applicable to cellulose triacetate fibres which have been dry, wet or melt spun by the methods of, for example, Specifications 748,772, 731,930, 726,900, 721,674, 719,853 and 687,414, [all in Group IV (a)], and those fibres having a safe-ironing point described in Specification 758,442, [Group IV (a)], may also be treated.  The process is also applicable to low acetyl cellulose acetate fibres which have been further acetylated to the desired value by the process of Specifications 448,816, 448,817 and 448,917, [all in Group IV].

[Also in Division A4] A windscreen wiper motor 22 is energized continuously when the movable contact 14 of a switch 15 is engaged with a terminal 18, but when the contact 14 engages a contact 19 a switch 35 de-energizes the motor 22 at the end of each wiping cycle and a delay device energizes the motor 22 intermittently at a time interval that can be selected to be greater than the period of one wiping cycle so that the wiper blade is stationary for a selected period at the end of each wiping cycle. The delay device comprises a capacitor 65 which when charged up through a variable resistor 52 and resistor 63 causes a transistor 55 to conduct and then discharges through the latter. The voltage at the base terminal 73 of the transistor 55 then rises to cause a rectifier 58 to conduct. The motor 22 is then energized through the rectifier 58 to move the wiper blade away from the parking position thus rotating a cam 32 to permit an arm 34 of a switch 35 to move from a contact 38 to a contact 37 to short circuit the rectifier 58. The motor 22 continues to operate until the wiper arm again returns to its parking position when the cam 32 forces arm 34 into engagement with contact 38. The capacitor 65 then charges again.
