Abstract: 1367780 Spring power-storing mechanisms; valves COMPAGNIE FRANCAISE DES PETROLES 26 Oct 1971 49808/71 Headings F2S and F2V A device which, in the event of a breakdown in an electrical supply system, rotates a shaft 7 to close a valve (not shown) in an oil pipe-line comprises a spring mechanism 2, 3, a coupling sleeve 6 connecting the shaft 7 and the spring mechanism 2,3, a holding member 19 which holds the spring mechanism 2, 3 in its powerstored stand-by position, a solenoid 13 continuously energized by the electrical supply, and a further spring 17 compressed by the solenoid core 12 in its energized state so that, when the current fails, the spring 17 projects the core 12 against the holding member 19 to release the spring mechanism 2, 3 which rotates the coupling sleeve 6 and with it the valve control shaft 7. The spring mechanism consists of two spring units 2, 3 connected by rods 8, 9 to arms 6a, 6b extending from the coupling sleeve 6 so as to tend to rotate the sleeve clockwise. When the current fails the bell-crank holding member 19 is pivoted to release the arm 6a which then rotates under the bias of springs 23, 28 and 17. Initially the springs 23, 28 expand simultaneously, the rod 8 being braked by a dashpot formed by a piston 21 and the spring casing. Then spring 28 expands alone, until a shoulder 86 on the rod 8 abuts a bush 29 and rocks spring-biased levers 30 (normally held by permanent magnets 33) over-centre to begin the final stage of shaft rotation, which is not damped. Opening of the valve (i.e. anti-clockwise rotation of the shaft 7) charges the spring unit and locks it in the powerstored position shown.

Abstract: 1,203,029. Valves. SAUNDERS VALVE CO. Ltd. 25 Oct., 1967 [8 Nov., 1966], No. 50038/66. Heading F2V. Butterfly valve comprising a casing main part 1 mounting the butterfly disc 3 on a pivot 4 for rotation about an axis offset from the general plane of the disc. A resilient seating ring has a major part 5 located in a recess 6 in one end of the casing part 1, the ring being clamped at a peripheral flange part by a casing flange 2. The ring part 5 is mounted with clearance on both side so as to follow any movement of the disc allowed by working clearance in the pivot, and so maintain sealings under the fluid pressure. The flow passages opened on opposite sides of the disc are arranged, as by recesses 22, 23, to reduce the dynamic torque, by reducing the differential increase in flow passage area as between opposite edges of the disc during opening movement from the seat which would occur with an offset circular disc disposed perpendicularly in a cylindrical bore. The recesses decrease in depth toward the pivot 4. In modifications, the flange is similarly recessed, or there may be a single pair of opposite recesses in the casing main part and flange. Instead of a recess in the flange the bore may be humped up locally at the lower side (Fig. 9, not shown).

Abstract: 507,181. Directive wireless systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and WRIGHT, G. M. Dec. 10, 1937, No. 34314. [Class 40 (v)] In a rotatable-frame aerial direction finder, quadrantal error is compensated by an auxiliary frame 3 geared to the main frame 1 so as to rotate at a 3: 1 velocity ratio in the same direction. The compensation may be adjusted by varying the relative number of turns on the aerials, by shunting one or each of the aerials by an adjustable impedance, or by coupling one or each of the aerials to the receiver through an adjustable transformer. Variation in the tuning with rotation may be compensated by connecting in series with the combined aerial circuit a mutual inductance comprising two coils which rotate with the frames 1 and 3 respectively. According to the Provisional Specification, the invention is also applicable to the radiogoniometer of a Bellini-Tosi system.

Title: Improvements in or relating to shoemaking
Inventor: LEE KENNETH
IPC: A43D11/14
Filed: 1963-12-27
Abstract: At at least two stages of manufacture of a shoe the upper is subjected for 15-30 seconds to a moist atmosphere of 65-80 DEG C., a lasting operation is performed shortly after each such mulling treatment, with at least 3 minutes elapsing between successive treatments, and when lasting has been completed the upper is subjected to a stream of air at 90-110 DEG C. for 2-3 minutes.  The shoes may be carried on a conveyer from one machine to another and the hot moist atmosphere directed against the uppers whilst on the conveyer through slot-like funnels, or the upper may be treated by use of a stationary apparatus associated with the appropriate lasting machine.  Preferably the atmosphere is directed against the ramp rearwards of the toe, and the toe and heel treated by overspill.  In the preferred arrangement lasting is carried out less than 6 minutes after the associated treatment, the atmosphere is at a temperature of 70-75 DEG C., each mulling time is about 18 seconds, and about 5 minutes elapses between treatments.  Optimum results on most leathers are achieved with 3 treatments each of 18 seconds in a moist atmosphere of 75 DEG C., followed by a treatment for 2 minutes with hot air at 90 DEG C.  Preferably a small amount of moisture is introduced into the upper, before pulling over, by a conventional mulling apparatus.
