Title: Sliding vane fluid-operated motor or engine
IPC: F01C1/352
Filed: 1971-09-14
Abstract: 1351695 Rotary positive-displacement machines GENERALVACUUM SpA 14 Sept 1971 [22 Sept 1970] 42686/71 Heading F1F In a sliding-vane motor inlet conduits for the working fluid e.g. compressed air, are constituted by ducts 19 and passageways 20 in a shaft 13 for the rotor 11, slots 17 for the vanes 18, and channels 28 in the trailing faces of the vanes. Flow of fluid into the passageways 20 from an admission port 27 is regulated by an arcuate slot 26 in a spring-loaded plate 21, which is held against rotation by a pin 24. The spent fluid is ejected through a recess 12 and port 130. To vary the output the plate 21 may be replaced by a similar one that can be rotated manually to alter the position of the arcuate slot, Figs. 5 and 6 (not shown). Alternatively, the effective length of the arcuate slot can be adjusted by a manually-movable sector-plate, Figs. 8 and 9 (not shown),. To facilitate arrangement of the motor as a first stage of a compound motor the port 130 may be replaced with a duct 31, which communicates with an inlet port 32 in the second stage, the latter being similar to the motor shown but lacking the ducts 19, passageways 20 and channels 28.

IPC: C08K3/28
Filed: 1959-12-16
Abstract: A particulate polymer containing at least 50% wt. of vinyl chloride is contacted with nitric oxide, nitrogen peroxide or a nitrosyl halide and subsequently moulded or extruded while it retains absorbed nitrogen compound to reduce discolouration. Examples illustrate the treatment of polyvinyl chloride, both as a dry powder and an aqueous slurry, and a vinyl chloride-vinyl acetate copolymer with nitric oxide. According to the Provisional Specification the treatment improves any halogen-containing polymer.

Abstract: 1,023,360. Cathode ray tube circuits. NORMALAIR Ltd. Oct. 27, 1964 [Oct. 30, 1963], No. 42754/63. Heading H4T. [Also in Division H1]. A display apparatus for indicating-in a submarine, for example-the physical attitude of a vehicle in relation to the earth, includes a cathode ray tube in which the control means for deflecting the electron beam includes a pendulous mass. For indicating the rolling motion of a vehicle, the deflecting coil assembly may be mounted on a collar rotatable with respect to the tube, and to which a weight is attached (Figs. 1 and 2, not shown), or the collar 2, Fig. 3, may include a gear ring 4 engaging with two spur gears associated, respectively, with an electric motor 7 and a first position transducer 8. A remotely positioned pendulous mass 3 operates a second position transducer 10, the signals from both the transducers being fed to an amplifier 9 and thence to the motor 7 to rotate the collar in sympathy with the movement of mass 3. In either embodiment the display may, alternatively, be arranged to move in the reverse sense to that of the pendulous mass, and the effect of centrifugal force may be compensated. For indicating pitching motion of a vehicle, a gimbal mounting permitting pivoting of the coil assembly is employed; and transmission of a signal to the deflection assembly collar from a remotely positioned pendulous mass may alternatively be by hydraulic or pneumatic means.

Abstract: 1479507 Gas analysis AUERGESELLSCHAFT GmbH 2 Oct 1974 [2 Oct 1973] 42796/74 Heading G1B A method for the automatic, continuous and quantitative measurement of the carbon halide content in gases, comprises heating a known quantity of such gases at 300-600‹C in the presence of water vapour and catalysts to form the corresponding halohydracid which is then washed with a known quantity of water, the halohydracid wholly dissolving and subsequently dissociating in the water, and measuring the ion concentration in this water so as to indicate the carbon halide content in the gas. The ion concentration may be detected by measuring the pH value or the conductivity of the washing water. The catalyst may be platinium, platinum black, quartz and rare earth oxides. In an embodiment, the catalyst may be in the form of a quartz tube provided with electrical heating means, and gases catalytically heated in this tube are impinged upon a portion of unrolled moistened reaction paper.

Abstract: 920,153. Counters. GRETAG A.G. Nov. 30, 1961 [Dec. 3, 1960], No. 42923/61. Class 106(1). Excessive wear on the lower order wheels of a counter is avoided by arranging that transfer and zeroizing is effected by power stored in springs and by using low-friction materials. Counter drive. Operation of driving magnet 39 rocks lever 46 clockwise against the action of spring 47 and withdraws pawl 48 to the dotted-line position of Fig. 6. De-energization of the magnet permits spring 47 to drive pawl 48 leftwards so advancing the lowest order numeral wheel via toothed wheel 52. The movement of pawl 48 is limited by a stop 56 of resilient material. The numeral wheel is held normally against reverse movement by pawl 19, Fig. 3. Transfer. As a numeral wheel rotates an associated spiral cam 4 acting on roller 12 swings lever 10, Fig. 3, counter-clockwise, stretching spring 13. At transfer the lever 10 is turned sufficiently for pawl 14 to slip over the edge of the next tooth on wheel 3 of next higher denomination. Roller 12 then drops off the high point of cam 4 assisted by the spring 13, whereby the pawl drives the wheel 3 one step until arrested by resilient stop 57. Zeroizing. Magnet 31, Fig. 7, is energized to rock shaft 9 so driving shaft 22 upwards to withdraw the locking pawls 19 from the wheels. Levers 25, Fig. 5, withdraw transfer pawls 14 and leave them in contact with the opposite side of stops 57. A projection 55, Fig. 6, likewise engages pin 54 to disable driving pawl 50. Spring 13 then acts through lever 10, roller 12, and spiral cam 4 to return all numeral wheels to zero position. Zeroizing may be effected by manual depression of rod 71, Fig. 7.

Title: Process for stabilizing solutions of aliphatic percarboxylic acids
IPC: C07C407/00
Filed: 1965-10-21
Abstract: Solutions of aliphatic percarboxylic acids in inert organic solvents are stabilized by the addition of quinoline, or an acid addition salt thereof, and a condensed phosphate of an alkali metal.

Specified solutions are those of peracetic acid in acetone, methyl acetate, ethyl acetate or mixtures of these solvents with acetic acid. Specified condensed phosphates are sodium tripolyphosphate or hexametaphosphate.  Quinoline acid addition salts which may be used are those derived from HCl, H2SO4, orthophosphoric or acetic acid.  The stabilizing effect of the quinoline may be due to the formation of the N-oxide in the presence of the peracid.
