Patent GB-497215-A (GB)
Title: An improved composition for inhibiting the growth of rust on iron or steel surfaces
IPC: C09D5/08
Filed: 1937-04-14
Abstract: An anti-rust coating-composition comprises 10 ozs. of potassium hydroxide dissolved in one gallon of an alcohol, an equal volume of a petroleum spirit, oil or grease, such as mineral turpentine, with which the alcoholic solution of potassium hydroxide is miscible, and 25 gallons of paint, varnish or the like.  Ethyl alcohol alone, as a solvent for the potassium hydroxide, is stated to be unsuitable, as the solution is not readily miscible with the other ingredients of the composition, but suitable specified alcohols are secondary butyl alcohol, tertiary butyl alcohol, isopropyl alcohol, or mixtures of these with ethyl alcohol.  When the paint contains fatty acid, e.g. linseed oil containing free fatty acid, alkaline pigments are added to neutralize the fatty acid, but when the paint is neutral, e.g. a neutral asphaltic paint, no neutralizing pigments are necessary. Specification 377,484 is referred to.

Title: Improvements in apparatus for and methods of producing cement clinker
IPC: F27B7/38
Filed: 1937-04-20
Abstract: 487,090. Rotary cement kilns. VANDERWERP, H. April 20, 1937, No. 11293. [Class 51 (ii)] In making cement clinker by heating cement materials to sinter them and then cooling by means of air, the cooling air is directly applied to the clinker when it has reached its highest temperature in a plane at right-angles to its direction of travel, and is confined to the zone occupied by the heap of clinker to be quenched, in order to effect a rapid quenching action without the clinker being compelled to change its general direction of travel between the sintering and cooling zones. Clinker which has been burnt in a rotary kiln 1 passes over a slightly constricted portion 3 of the refractory lining into an extension B of the kiln where it is cooled by air injected through semi-cylindrical tuyere members b<1>. The tuyere members are mounted on and receive air from longitudinal air-flues 6, each divided by a transverse partition 8 into two sections 9 and 10 which receive air through tubular connections 39, 48 and 40, 49, and ports 50, 51 in a flat annulus 49<1> secured to the ends 48, 49 of the tubes, from arcuate slots 60, 61 in a non-rotating, annular chest C surrounding the kiln and supplied with air under pressure. Valves 64 and 65 operated by hand wheels 69 control the flow of air through slots 60, 61 to the sections 9, 10. The slots 60, 61 are so placed and of such a length that air is supplied only to such tuyeres as are covered by the stream of clinker passing through the kiln, and may be altered inlength by means of sliding dampers at the ends operated by rack-and-pinion. The tuyere members b<1>, together with the air flues consisting of hollow, trough-like metal members, slotted to communicate with the tuyeres, are secured to the kiln wall by bolts 7 centrally of each tuyere member. The spaces between adjacent flues are filled with refractory lining. The wind-chest C is. mounted for limited movement parallel to the kiln axis, and is pressed resiliently against the flat annulus 49<1>. Further ports may be provided in the wind-chest C to supply air to uncovered tuyere members to prevent overheating.

Abstract: 693,756. Printing-apparatus. HALLEY & SONS, Ltd., J., and HALLEY, A. M. Mav 4, 1951 [May 8, 1950], No. 11316/50. Class 100(ii) Rotary photogravure printing-apparatus has a doctor blade adjustably mounted in a housing, the blade being held by expandable clamps in a carrier which can be given a lateral sliding motion in the housing by eccentrics carried by rotatable spaced studs in the housing. The cylindrical housing 3 has a longitudinal slot 4 in which a carrier 5 can slide. The carrier 5 has a longitudinal recess 6 in which the doctor blade 7, a thin metal strip, is held by a strip 8 of heavier gauge metal and expandable clamps or quoins 9. The blade 7 is first inserted, then the strip 8 is placed above it. The quoins, each of which comprises two sections 9a having inclined inner faces co-operating with a wedge 9b, are then placed at intervals along the recess 6. By tightening a screw 9c the sections 9a are forced apart to clamp the blade 7. The carrier 5 has longitudinal slots 5a receiving eccentric portions 10a of rotatable plugs 10 mounted in apertures in the housing 3. Pins 12 carrying lock nuts 13 pass through the plugs to secure them against rotation. To adjust the blade the lock nuts are loosened and the plugs rotated to move the carrier 5 laterally in the recess and thus alter the distance the blade extends out of the housing.

IPC: F15B13/02
Filed: 1952-05-05
Abstract: 765,333. Fluid-pressure servomotor control systems. FUJII, I. May 5, 1952 [May 3, 1951; May 3, 1951; May 3, 1951; July 16, 1951], No. 11351/52. Class 135. The road wheels of a vehicle are driven by rotary motors 24a, Fig. 1, supplied with liquid under pressure by a pump 2a driven by prime mover 1a, the quantity and direction of the liquid being controlled by a valve A<SP>1</SP> actuated by a piston 9a which is controlled by valve C operated manually by lever 13a. Movement of the piston 78 of valve C causes movement of piston 9a which moves a cylinder 71 around piston 78 to shut off flow through the valve. The piston 9a also actuates a by-pass valve 53a in the conduits 3a, 4a between the pump and valve A<SP>1</SP>. In another arrangement, a single rotary motor drives the drum of a winch. In yet another arrangement, motors 5f, Fig.. 8, drive the endless tracks of a vehicle and are supplied under the control of pedal 26c in similar manner to the motors of Fig. 1. The motor swash plates 5d are adjustable differentially, for steering, by pistons 13c each controlled by a valve C<SP>1</SP> similar to valve C, the two valves C<SP>1</SP> being actuated by lever 16c pivoted at 17c and turnable by handle 18c. In a modification, valve A<SP>1</SP> in the conduits 3a, 4a controls two pistons acting at opposite ends of a ship's rudder bar. In another modification, a rod 36b, Fig. 5, is manually moved axially to turn quadrant 27b about pivot 28c, thus turning planet 25b to actuate the piston of valve C controlling pistons 19b. This piston operates by-pass valve 44b in conduits 40b, 41b and valve A<SP>1</SP>, which controls pistons 7b, 8b to turn rudder 11b, The rudder moves rod 31b axially to turn quadrant 29b about pivot 30b and restore the piston of valve C and hence the piston 19b to their central positions. Valve A<SP>1</SP> is thus closed to stop movement of the rudder. Rods 31b, 36b are interconnected by a piston and cylinder 35b allowing lost-motion.

[Class 99 (ii)] [Also in Group XXII] In a machine for making tubes of paper, fibre, thin metal &c. which may be cut into sections, a strip continuous 7 of the material, coated with adhesive, if necessary, is fed forwards by a reciprocating mandrel 3 through a curved former 22, which shapes it into tubular form, the strip being clamped to the mandrel during its forward stroke and released on the return. The strip, drawn from a roll 8, may be gummed by rollers 12, 13 and dried in a heated chamber 19 before passing between the former and the mandrel. The mandrel is reciprocated by a cam 45 driven from a shaft 34, and is guided in a bracket 2 and by a rod 4 fixed to it and sliding in a second bracket 5. The strip is held to the mandrel during its forward stroke by a clamp 62 mounted on, and sliding with, the rod 4, and opened and closed by an elongated cam 73 on the shaft 34. When released from the mandrel, the strip is clamped against the former 22 by a block 144 operated by a cam 150. The overlapping edges of the strip are pressed together to form the seam, by a cam-controlled presser-block133. The end of the tube is cut off by a disc-knife 161, which travels around the mandrel at the end of the feed-stroke. The knife is pressed against the tube, and is driven, by a continually rotating cone-shaped member 162, which is moved axially by a cam so as to engage and drive the knife by friction. In a modification, the mandrel is in three telescopic sections, the end sections being caused to move forwards whilst the middle section returns, so as to impart a continuous movement to the tube.
