Abstract: 947,478. Disc clutches and brakes. CLARK EQUIPMENT CO. Dec. 4, 1962 [Dec. 4, 1961], No. 45824/62. Headings F2C, F2E and F2F. A disc clutch or brake is cooled by a liquidgas mixture produced by feeding the separate constituents, preferably oil and air, into a mixing chamber, from which it is fed to the discs. In the clutch shown discs 32, 34 are carried by a hub 24 and drum 28 respectively splined to shafts 14, 16, the discs being engaged by pressure liquid supplied through passages 54, 52, 46, 44 to an annular actuator piston 40, the assembly being enclosed in a sealed casing 12. Cooling oil is supplied from two sources, a first pipe 74 and a second pipe 86 fitted with a nozzle 88, from which latter it discharges into a chamber formed by a cap 90 enclosing the ends of shaft 14 and drum 24 and mixes with air entering through holes 94 in the cap. The foaming liquid produced passes from the chamber to axial passages 58 in drum 24 from which it is discharged through radial openings 70 over the discs 32, 34, finally escaping into casing 12 through radial openings 72 in drum 28, the outward flow over the discs promoting the return flow of separated air through the holes 94. In the arrangement shown the discs 32 are made of steel, while the discs 34 are of sintered bronze and have intersecting groove patterns on both faces for the passage of the cooling medium. The groves may be formed on discs 32 however. The operating liquid is fed from passage 54 to a pressure chamber divided into two portions 42a, 42b by a ring member 43 secured to the end wall of drum 28, the liquid first entering chamber 42a to ensure rapid initial movement of piston 40, and then passing into the second chamber 42b for pressure build-up on the piston.

To enable a punch and die set, or a plurality of punch and die sets to be correctly positioned on the bolster of a press, means are provided to relieve the pressure of a stripping spring acting on the punch, so that it can be passed through a template into engagement with the die and while so engaged, the die set can be clamped to the bolster. The die set comprises a frame having a lower limb 11 which supports a die 12 and which has an opening 11a for a clamp bolt. An upper limb 14 of the frame supports a punch 13 which slides through a stripper bush 16. The bush 16 is itself slidable in the frame and is biased upwardly by a light spring 20. A stripping spring 21 bears on the head of the stripper bush and engages the underside of a collar 23 which surrounds an intermediate portion 22 of the punch. In the upper surface of the collar 23 is a diametral slot 24 and on the enlarged head of the punch are two flats 26. When the collar 23 is turned through 90 degrees the flats 26 drop into the slot 24 and the pressure of the stripping spring is relieved. In a modification, Fig. 2 (not shown), the stripping spring (21a) acts between the head (27) of the punch and a flat plate (28) which bridges a slot (29) in the frame and which is secured by a screw (30). By slackening the screw (30) the plate can be rotated through 90 degrees about the punch and then drops into the slot (29) so that the pressure of the stripping spring is relieved and the punch can be moved into engagement with the die.

Abstract: 1,157,318. Titania. P.P.G. INDUSTRIES Inc. 17 Oct., 1966 [18 Oct., 1965(2)], No. 46258/66. Heading C1N. TiO 2  is coated with a hydrous metal oxide (including SiO 2 ) by forming an aqueous slurry of the TiO 2  in the presence of a hydrolysable metal compound; the latter is hydrolysed in the presence of a basic ion which will form a volatile salt with the anion of the metal compound. The volatile salt is removed and coated TiO 2  recovered substantially free from volatile salt. The slurry may be volatilized at the same time as the volatile salt, e.g. by spray drying, at a temperature high enough to volatilize both water and the volatile salt but below the temperature of discoloration of the pigment. Alternatively, the coated TiO 2  may be recovered without evaporation, e.g. by filtration, and subsequently heated to remove the volatile salt. The basic ion may be ammonium and the metal compound may be a halide of Ti, Al or Si or titanium or aluminium sulphate. Other metals and anions are listed at length. The slurry may be digested, e.g. at pH 5À2 to 9.5, for from 5 minutes to 6 hours at 30-100‹ C. after addition of metal oxide and before spray drying, evaporation or filtration. The slurry may contain <85% by wt. TiO 2 . Spray drying may be carried out at <700‹ C. and at a pressure of 10 to 20 Ibs. per sq. in. absolute pressure.

Abstract: 1,133,751. Single lens reflex cameras with focal plane shutters. EASTMAN KODAK CO. Nov. 5, 1965[Nov.7, 1964], No.46923/65. Heading G2A. A single lens mirror reflex camera comprises a control disc 8 rotated, on operation of a camera release, so as to impart a sinusoidal motion to a lever 7 controlling movement of the mirror 1 to move the latter through a compound movement from the viewing to the taking position and to release the focal plane shutter 33, 34 for rundown thereof, the shutter, on completion of its rundown, releasing the disc 8 to permit it to complete its rotation, thereby returning the mirror to the viewing position; operation of the camera release also releases a diaphragm setting mechanism 25-29 to permit the diaphragm to assume a setting pre-selected by rotation of a ring 39. To make an exposure, a release button is moved, thus pivoting a lever 20 in the direction A and freeing the disc 8 to rotate under spring action, thereby moving the lever 7. Pivoting the lever 20 also frees the ring 25 and hence the diaphragm setting ring 29 to rotate until a projection 25a engages the abutment 39a of the ring 39 at the pre-selected diaphragm aperture setting. Then a pin 8c of the disc 8 pivots a lever 37 anti-clockwise (as seen in the Figure) to disengage a ratchet 36 from the shutter control gear 35 allowing the first curtain 33 to run down. The disc 8 is prevented from rotating further by a lever 32, a stop 32b thereof engaging a projection 8b. The second curtain 34 is released to run down after a pre-selected time by means of a gear 38 carrying a cam 38a which, at the end of the run down of the curtain 34, pivots the lever 32 out of the path of the disc 8 thereby freeing the disc to complete one revolution and freeing a slide 30 to move in the direction C so as to reset the rings 25, 29 in the position of maximum diaphragm aperture. Retensioning of springs 10, 40, retensioning of the shutter and transporting of the film are effected by manually pivoting the lever 18 in the direction D, which lever may be replaced by an electric or a clockwork motor.

Abstract: 1,126,062. Liquid fuel rocket motors. PLESSEY - UK Ltd. Dec. 15, 1965 [Nov. 30, 1964], No.48501/64. Heading F1J. The invention relates to a rocket motor which operates by combustion of a monofuel such as isopropyl nitrate which is supplied to the combustion chamber by a pump driven by a gas turbine. The rocket motor shown comprises a combustion chamber 1 having a monofuel injector 3 at one end and a propulsion nozzle 2 at the outer end, the nozzle 2 being initially closed by means of a burster disc 18. The unit comprises also a breech 14 containing a cordite charge 15 which may be fired by means of a detonator 19 which itself is fired by a firing pin 16. The breech 14 communicates through a passage 17 with the combustion chamber 1 and also with an inlet nozzle 12 of a gas turbine 11, the turbine being drivably connected to a monofuel pump 4. Fuel delivered by the pump 4 passes through line 22 to an on-off valve 5, then through a control valve 8 which is in parallel flow with a restrictor 7. The fuel then passes through a pressurizing valve 10 to the injector 3 into the chamber 1. At starting, the cordite charge 15 is fired and the combustion gases drive the turbine 11 and also enter the chamber 1 which is thereby pressurized, the nozzle outlet 2 being closed by the burster disc 18. Monofuel now discharges into the chamber through the injector 3 and the resulting increase in pressure bursts the disc 18 and the gases discharge through the propulsion nozzle. Gases also pass from the chamber 1 through the passage 13 to the turbine inlet nozzle 12 so that the turbine continues to be driven when the cordite charge is spent.
