[Also in Division F2] A projectile launcher has a starter-brake system for accelerating and decelerating a rotor system 14 thereof, the system comprising a housing 100 fixed to the rotor housing 10, a shaft 12 fixed to the housing 100, a gearing assembly including a sun gear 112, planetary gears 124 mounted on a planetary arm 118 and a ring gear 120 mounted for operation about the axis of the shaft 12. A spring 130 is connected between the shaft 12 and the sun gear 112 and is wound up by rotation of the ring gear 120. On the spring 130 being wound a dog engages a detent 134 of the planetary arm 118 to prevent an unwinding thereof, a unidirectional clutch 158 being interposed between the sun gear 112 and the planetary arm 118 to connect the sun gear 112 and arm 118 together for rotation in the unwinding direction of the spring 130. When the detent 134 is freed from the dog, the spring unwinds and rotates the ring gear 120 through the sun gear 112 and planetary gears 124. In the construction shown in Fig. 1 the ring gear 120 is connected to the rotor 14. The rotor 14 during the firing of the gun is actuated by gas bled from the barrels through a piston and cylinder 70, 64 and cam 82, 84, 86, 88 assemblies. Projectiles 54 are fed into alignment with the bevels 30 from a magazine 63 in canisters 50, a sleeve assembly 40 interposed between the canister and a barrel being movable away from the canister 50 after the projectile has been fired to facilitate the loading of a further canister and projectile assembly.

A coil holder assembly for shaping coil ends of stators during winding comprises coil holders having two parts hinged to each other, a first part 4 provided with a spar-like portion 7 which ends in a tongue 8 extending into a stator groove and a second part 3 for engagement with a coil holder receiving ring 1, a device being provided for the storage, supply and removal of the coil holders comprising a base member 1,2, which has clamping elements 13 for clamping the first part 4 of the holders, and an axially displaceable mounting member 14 having grippers 15, 15<SP>1</SP> for gripping the spar-like portions. After the stator has been wound, the member 14 is moved to the right in Fig. 1 and the parts 3 perform a pivotal movement as they are drawn clear of the end turns. This pivotal movement is limited by stops 19, 19<SP>1</SP> and the movement of the member 14 continues until the coil holders are clear of the windings. When an unwound stator is placed in the assembly the coil holders 3, 4 are positioned as shown in Fig. 1 and a detachable ring is placed over the grippers 15, 15<SP>1</SP> so that their outer diameter is smaller than the inner diameter formed by the portions 7. The device is then moved towards the stator until the parts 3 contact the stator end face and they are secured by the ring 1. The device is then withdrawn and the detachable ring removed from the grippers 15, 15<SP>1</SP>, which are interconnected by a circumferential spring 18 to move them radially outwardly and engage the portions 7.

Title: Process for the production of smokeless coal agglomerates
IPC: C10L5/28
Filed: 1963-11-22
Abstract: Smokeless coal agglomerates are produced by oxidizing agglomerates formed from a mixture of (i) fusible coal, (ii) pitch and optionally (iii) one or more coals in the range anthracite coals to fusing coals (the latter being bituminous coals containing more than 13% volatile matter which on heating become pourable) at a temperature which is below the distillation temperature of any constituent and which is between Tg and Tm, where Tg is the temperature at which the contraction of the fusible coal is at a maximum and Tm is the temperature at which the contraction of the fusible coal is at a maximum and Tm is the temperature at which contraction of the mixture is at a maximum, as shown by the curve of volume variation against temperature, Afnor Standard M11,004. Preferably the oxidation is effected with a gas containing 3-5% oxygen using a heating rate of 1 DEG  to 8 DEG  C. per minute.  When (iii) is an anthracite coal (i) is preferably less than 1 mm. particle size and constitutes 5-40% of the mixture.  The process may be carried out by passing the agglomerates on a horizontal conveyer through a furnace similar to that claimed in Specification 908,606.  Examples disclose mixtures in the ranges (i) 12-45%, (ii) 7-75%, (iii) 48-80.5% heated to 330-425 DEG  C., and a mixture (i) 93%, (ii) 7%.

Title: Process for fabricating a screen structure for a cathode ray tube
IPC: H01J9/227
Filed: 1970-09-30
Abstract: 1324377 Luminescent screens RCA CORPORATION 30 Sept 1970 [1 Oct 1969] 46509/70 Heading H1D A method of fabricating a C.R.T. screen structure comprises covering discrete surface areas with phosphor mixed with a photo resist material insolubilized by light, applying a light opaque dye 11a as a solution to the phosphor deposits and insolubilizing by applying a mordant solution, applying to the covered and uncovered areas a screen material mixed with a soluble photo-resist material, e.g. dichromate sensitized P.V.A., projecting radiation through the screen support to insolubilize the overcoating mixture between the phosphor deposits and removing the remaining overcoat mixture. The photo-resist with the phosphor may be P.V.A., fish glue or gelatine, and the dye and mordant solutions may be aqueous e.g. a mordant solution of 2 % by wt. aluminium chloride, 1% by wt. barium acetate or aluminium ammonium sulphate and an aqueous dye solution of 5% black dye with 1À25% P.V.A. or a red dye may be used. The overcoating mixture may be lightabsorbing, e.g. of graphite, to produce a matrix type screen, or may be of a phosphor material. Overcoating 12 may be of water, graphite particles and a dichromated sensitized polyvinyl alcohol, and after drying, exposed to U.V. lamps 13. The dye and mordant are preferably thermally decomposed with the organic photoresist on bake-out. The production of an insolubilized dye prior to the step of selective dye removal ensures the insolubilized dye is not leached or removed from the phosphor coated areas in any subsequent process step and the dye area ensures less than 2% U.V. transmission. As exemplified, dye areas 11a are formed by initially coating the entire screen area with the dye solution, insolubiilzing, and then washing with water spray, the insoluble dye layer then washing off the glass area. The process may be applied to two types of phosphor dots, the remaining screen area being covered with a third phosphor. Colour TV shadow mask tubes are exemplified and dot type phosphor screens are instanced and also grid and bar type screens.
