Patent GB-1266767-A (GB)
IPC: F41A25/02
Filed: 1969-05-30
Abstract: 1,266,767. Recuperator mechanism for guns. RHEINMETALL G.m.b.H. 30 May, 1969 [6 July, 1968], No. 27479/69. Heading F3C.   A gun has a pneumatic barrel recuperator the recuperator comprising a pair of piston and cylinder assemblies 1, 8; 2, 11 connected mechanically in parallel as by an entrainment means 4 of a breech plate 5 of the barrel 6. One 1, 8 of the piston and cylinder assemblies is arranged in normal use to act constantly on the barrel 6 of the gun whereas the other 2, 11 of the assemblies has a lost motion connection relative to the barrel. To this end energy, e.g. in the form of pressurized oil, can be fed to and stored in the other assembly 2, 11 and released at an appropriate point in the recoil of the gun. The pressurized oil is supplied by a hand pump 15 through a one way valve 19 and two changeover valves 27, 16. If the barrel recoils sufficiently to be returned by the action of both assemblies without the aforesaid energy, i.e. a distance x, the valve 16 is actuated by a trigger 20 on the barrel to vent the pressurized oil to a reservoir 14. If it is desired to retract the barrel of the gun for travelling purposes pressurized oil is fed to the assembly 1, 8 by changing over valve 27. The assembly 1, 8 is vented of oil through a valve 26.

Abstract: 1296811 Automatic steering control SPERRY RAND CORP 16 Jan 1970 [17 Jan 1969] 2236/70 Heading G3R A craft is automatically steered to take up and follow a desired course in response to the difference between a signal corresponding to the difference between the direction of the desired course and the craft heading and a signal corresponding to the drift angle of the craft. In an aircraft automatic pilot, Fig.1, a knob 16 is set to select a course intercepting a VOR/localizer radio beam and produce at 15 a signal corresponding to the difference between this course and the aircraft heading which is compared at 26 with a filtered signal, from a unit 13 of an inertial navigation device 11, corresponding to the drift angle of the aircraft, so that any difference is effective through a limiter 36 to control the ailerons and thereby steer the aircraft so as to approach the beam asymptotically. A radio  receiver 17 applies through a limiter 35 a correction signal dependent on displacement of the aircraft from the beam centre and inertial naviga-  tion unit 12 applies a signal corresponding to roll angle and therefore turn acceleration. When the aircraft is on the beam, a switch 29 is closed so that the difference between course error and drift angle is washed out by a lag circuit 28. Improper operation of inertial navigation device 11 is detected by a unit 14 which operates a switch 24 to disconnect the drift angle signal, a switch 27 to disconnect the above-mentioned difference signal, and switches 21 and 34 to introduce a roll attitude signal lagged at 23 and a rate of beam displacement signal developed at 33 for damping purposes. In addition, the gain of lag circuit 28 is increased to reduce the time to wash out the effect of the opening of switch 24.

Abstract: 1312803 Knitting machines PLATT INTERNATIONAL Ltd 13 Aug 1971 [14 May 1970] 23425/70 Heading D1C A pair of measuring rollers 2, 3 which engage the yarn build 1 on the beam of a warp knitting machine at circumferentially spaced points are carried on a pivotal mounting and drive an output member 19 rotatable about the axis of the mounting which acts through control means to control the rotational speed of the beam so that the yarn delivery speed is substantially constant. Rollers 2, 3 are rotatable on a rocker plate 7 pivoted on a hollow shaft 9 secured to a column 11 carried on a mounting block 12 freely rotatable on a hollow shaft 13 encircled by a coil spring 14 which biasses rollers 2, 3 against yarn build 1. A timing belt 26 transmitts the drive from rollers 2, 3 to shaft 19 carrying a second sprocket 21 which through chains and sprockets drives a differential 33. A second input shaft 34 to differential 33 is driven through gearing from a steplessly adjustable variable speed drive unit 41 controlled by hand wheel 47 and having a constant speed input shaft 43 driven from main shaft 45. Shaft 45 also drives a shaft 50 carrying the warp beam through a variable speed drive unit 48 whose control shaft 51 is driven by the output shaft 35 of differential 33. When yarn is being delivered at the required speed shafts 32, 34 are driven at the same speed and therefore output shaft 35 is at a standstill. As the delivery speed falls, shaft 35 begins to turn and adjusts unit 48 to increase the speed of shaft 50 until equilibrium is achieved again.

Abstract: 1341533 Metal-coated glass-ceramic ISHIZUKA GARASU KK 23 Feb 1972 8366/72 Heading C1M A metal coated glass-ceramic article is produced by the steps of melting a glass forming batch which contains a nucleating agent and at least one compound of copper and/or silver in an amount such that the batch contains 0À05 to 5% by weight of the metal; forming the melt into a glass article of desired configuration; heating the article in a reducing atmosphere both to devitrify the glass and to cause the copper or silver ions to migrate to the surface of the article and be reduced to discrete metal particles; heating in an oxidizing atmosphere to oxidize the particles and thereby cause them to coalesce; and finally heating again in a reducing atmosphere to reduce the metal oxide to its metallic state. The first heating stop is carried out by raising the temperature of the glass article at a rate not exceeding 300‹ C. per hour to a temperature between the transition point of the glass and the melting point of the metal. The other two heating steps are carried out at a temperature between 200‹ C. and the melting point of the metal. The reducing atmosphere may consist of hydrogen, carbon dioxide, methane, ethane, propane, butane or town gas. The oxidizing atmosphere may be oxygen or air, and the reducing atmosphere may be purged with an inert gas such as nitrogen or helium. The glass-forming batch contains an oxide, halide, sulphite, sulphate, nitrate, phosphate or hydroxide of copper and/or silver. The batch also contains in percentage by weight SiO 2  40-88; Al 2 O 3  1-35; LiO 2  0À5-40À7; MgO 0À5-30; ZnO 1-30; CaO 1-15; B 2 O 3  0-10; Mn 2 O 0-22; K 2 O 0-22; and PbO 0-15.

Patent IL-103073-A (IL)
Title: Disc-type depilation apparatus
IPC: A45D26/00
Filed: 1992-09-07
Abstract: A depilation apparatus comprising a number of pinching discs (35) which are coupled to a drive shaft (7) in positions which are mutually rotated through 120 DEG about the drive shaft (7). Each pair of adjoining pinching discs (35) is pivotable under the influence of a compression member (83) into a pinching position in which two cooperating pinching surfaces (67, 63) exert a pinching force on one another near a depilation opening (3). The pivot axis (113) of each pair of pinching discs (35) is determined by a stud part (55b) of a bipartite stud (55) of one of the two pinching discs (35) of the pair and by the mutually facing steps (41) of the two pinching discs (35) of the pair. The cooperating pinching surfaces (67, 63) of the pair are supported on either side in the pinching position by the stud parts (55b) and (55a), respectively, of the bipartite studs (55) of the adjoining pinching discs (35), so that a substantially straight force transmission path is created in the pinching position near the depilation opening (3). Each pair of cooperating pinching discs is provided with a delaying stud (59) by which the pinching position is temporarily delayed after tilting of the pinching discs (35) about the pivot axis (113). Furthermore, each pair of cooperating pinching surfaces (67, 63) is provided with two nose-shaped combs (73, 71) which are bent into a hair-trapping funnel. The use of the bipartite studs (55) achieves a high pinching force between the cooperating pinching surfaces (37, 63), while the use of the delaying stud creates a quick build-up of the maximum pinching force after the pinching discs (35) have entered the pinching position. <IMAGE>
