Abstract: 1,127,483. Signal rockets. PYROTECHNIK SILBERHUTTE VEB. 21 Feb., 1966, No. 7484/66. Heading F3A. With the object of improving the thrust and rotational efficiency, a closure and nozzle plate 1, for signal rockets intended to be launched from the hand, has a number of gas passages inclined to the rocket axis to cause rotation in flight. Each passage includes an intermediate portion 8 of smaller cross-sectional area than the inlet and outlet apertures 9 of the passage, and the walls are inclined outwardly relative to the axis 3 of the passage in a section corresponding generally to the rotational direction to define a largest aperture angle. This angle, in each of the passage portions upstream and downstream of the area 8, has a leg 5 which is parallel to the rocket axis. The passages may be shaped so that the cross-section 8 is oval or square, Figs. 4 and 5 (not shown).

Title: Improvements in and relating to spars for wings and like structural parts of aircraft
IPC: B64C3/18
Filed: 1941-06-17
Abstract: 547,178. Aircraft wing spars. MARTIN, J., and MARTIN-BAKER AIRCRAFT CO., Ltd., June 17, 1941, No. 7637. [Class 4] A spar for a wing or like structural part of an aircraft comprises a girder having a web reinforced at or near its upper and lower edges on one or both sides by a series of strips or laminations the length and thickness of the various strips being graduated to meet the stresses borne by the various parts of the spar, substantial thickness booms being provided at the root end of the spar. A wing spar is shown having a plate web 1 reinforced at its upper and lower edges at one side by steel booms 3 extending out as far as the first joint 1a in the web. These booms are recessed at 5a, 6a to take overlapping strips 5, 6 forming lighter reinforcements extending towards but not as far as the spar tips where the web only has secured to it the angle members 7, 8 for attachment to the wing cover. The angle members 7 on one side of the spar extend for its whole length being secured directly to the web, the angle members on the other side being secured to the members 3, 5 and 6 except at the tip. At the root of the spar the members 3 are formed into eyes 4 and are braced together by ribbed brackets 12. To take torsion a substantially D-shaped extension is connected to the spar and is formed by plates 21, 22, angle members 26 and a plate 25, Fig. 4, secured together by countersunk bolts. A nose piece is secured to the angle-members 26 and comprises a plate 28 with stiffening ribs 29. Girders of channel or box form may be similarly reinforced. The webs and angle strips also may be laminated.

Title: A piston for a rotary piston i.c. engine
IPC: F02B55/02
Filed: 1966-02-22
Abstract: 1,088,302. Rotary-piston I. C. engines. KARL SCHMIDT G. m.b.H. Feb. 22, 1966 [March 27, 1965], No.7826/66. Heading F1F. In a rotary-piston I. C. engine of the trochoidal n and n + 1 lobe type, a light metal piston 1, Fig. 1a, eg, of aluminium alloy, includes in its bore a ferrous bearing adaptor 3 connected to the piston by interengaging teeth 2 with the tangent of the angle α Fig. 1b between a tooth flank and the corresponding radius of the piston equal to where L is the width of the tooth measured on the pitch circle and D the p. c. d. The angle a is chosen so that when the light metal piston and ferrous adaptor expand differentially at high temperature, the tooth flanks slide relatively to one another in their planes of contact without imposing any undue stresses on the parts. At the same time, advantage can be taken of the smaller bearing clearances which occur with ferrous bearing bushes. The adaptor, preferably of steel, may be made integral with or separate from the internally-toothed gear ring which is usually fixed to the pistons of engines of the n and n + 1 lobe type to give with the pinion fixed to the engine casing planetary motion of the piston.

Abstract: 898,816. Exercising devices. ELIA, P., and ELIA, K. June 20, 1960 [March 5, 1960], No. 7868/60. Class 132(1) Secured firmly to a heavy article, e.g. a gymnasium bench, are socket means, having socket axes lying in two mutually perpendicular directions which socket means receive a hand grip device so as to extend in either of these directions. As shown, Fig. 2, the socket means comprise parallel tubes 3, 4 (e.g. gas piping) each welded near one end to a common steel plate 5 and at its other end to an individual upstanding plate 6 adjacent which each tube carries a peg or the like 8. Collars 11, one of which has a screw and wing nut 13 to secure the hand grip device, are welded to a steel plate 12 which is secured to the bench leg with the collars aligned axially with pegs 8. The hand grip device comprises tubes 14, 15 secured to a tube 16 which projects at the sides to form hand grips. Welded between and perpendicular to tubes 3 and 4 in alignment with bores in one of the tubes 3 is a tube 9 containing a compression spring which urges a bolt with a handle projecting through a slot 10 in tube 9 into engagement with bores in tube 3. When tubes 14, 15 are inserted in tubes 3, 4, holes in tube 14 are engaged by the bolt in tube 9 and, when tubes 14, 15 pass through collars or brackets 11 and engage pegs 8, they are held by wing nut 13. In a modification, Fig. 4, L-shaped members each consisting of two pipes 17, 18 welded together are mounted spaced apart and parallel on plates 5, 51 and 5<SP>11</SP> by which the device is secured to the bench.

Title: Electrical control mechanism
IPC: D04B15/66
Filed: 1954-03-18
Abstract: 765,840. Switching systems. COBERT, A. J. March 18, 1954 [March 30, 1953], No. 7882/54. Class 38 (4). [Also in Group XXXVII] Electrical control mechanism comprises a number of bars 12 of conducting material each connected to a regulating circuit for a part of a knitting or like machine. A pattern card 13 of insulating material having perforations 14 permits selective engagement between the contact bars and fingers 15 mounted on carriage 16. An electric pilot motor 20 is used to drive the carriage upwardly into its initial operating position, the motor being coupled to chains 23, 23<SP>1</SP>, through a solenoid-operated slip clutch 18 and the chains being adapted to engage brackets 26, 26<SP>1</SP> on the carriage. As the carriage is raised, a counterweight 29 is lowered, upward movement of the carriage being stopped by means of a limit switch 31. A solenoid 32 enables the carriage to be moved downwardly in definite steps, the solenoid being coupled through Bowden wire 33 to a pawl mounted on the carriage and co-operating with a rack 39. The contact fingers 15 are held away from the pattern card when the carriage 16 is being raised to the starting position, a solenoid 52 being energized to move a rock shaft 44 for this purpose. Normally, the contact fingers are biased against the pattern card by means of a spring. A cam driven by a part of the machine under control is adapted to operate a switch for sending current-pulses at regular intervals to a counter comprising a number of rotary switches and relays. If it is desired to delay the carriage 16 in a given position for a predetermined count, this is set up on the pattern card so that one of the rotary switches forming part of the counter is energized through a contact finger 15 and the circuit to the solenoid 32 is interrupted until the count is completed. If no count has been set up, then each impulse from the cam-operated switch will immediately index the carriage downwardly by one notch. At the end of a working cycle of the machine being controlled, the carriage 16 is automatically returned to the starting position by means of the motor 20. Specification 765,839, [Group VIII], is referred to.
