IPC: F42B22/14
Filed: 1918-05-31
Abstract: 128,703. Crow, A. B. May 31, 1918 Mines, marine.-Consists in means for holding a mine or group of mines at a depth below normal until required to be put in action. As shown, a mine S is attached by a cable N to a plug K also attached to another cable C wound within a casing J on a cone A connected to a mooring by rings B. The inner end of the cable C is fixed to the cone by means of a pin D. To put the mine in action, an explosive charge A<7> is fired electrically from a distance through leads T. The explosion drives a piston E up against the plug K, which it expels. The mine S then rises to its active position, pulling the cable C out of the casing J with the help of buoys R. Reference has been directed by the Comptroller to Specification 3654/84.

Abstract: 526,635. End-catchers for spinning-machines. GESSNER AKT.-GES., E. March 23, 1939, No. 9195. Convention date, March 28, 1938. [Class 120 (ii)] Ring spinning frames are provided with mechanism for catching broken ends of threads or yam, which consists of a pair of rollers 9 arranged below the supply rollers 6 and driven at the same peripheral speed, and a trough 10 having a floor formed by a belt conveyer 14 working on rollers 15.

Title: A hydraulic transmission mechanism
IPC: F16D67/00
Filed: 1950-04-14
Abstract: 680,663. Hydro-mechanical variable-speed gear. CHATELET, H. J. G. April 10, 1951 [April 14, 1950], No. 9196/50. Class 80 (ii). [Also in Group XXIX] A hydraulic transmission mechanism utilizable on automotive vehicles between a driving shaft 2 and a driven shaft 16 for providing with a minimum of slippage progressively varying speed according to the rate of rotation of the motor and the resistant torque comprises a primary hydraulic coupling 20-21, a secondary hydraulic coupling 24-25 exerting a brake action, and a planetary gear train, the runner 21 of the primary coupling being rigid with the driven shaft 16 together with an element of the gear train, the impeller 20 being rigidly connected to a second element of the gear train together with the runner 24 of the secondary coupling, and the impeller of the latter being rigid with the driving shaft 2 together with a third element of the gear train, so that the reaction normally exerted upon the impeller of the primary hydraulic coupling due to the transmission of the driving torque through the gear train is braked by the co-operation of the impeller and the runner of the secondary hydraulic coupling. The driving shaft 2 is secured to a plate 3 carrying a casing 5-6. Fixed to the casing 5 are vanes 25 and the sun wheel 10 of the planetary gear, which wheel meshes with planet wheels 13 supported by a carrier 14 secured on the driven shaft 16 having the runner vanes 21 fastened thereto. The ring member 18 of the planetary gear is secured to the impeller 20 which carries the vanes 24. When the engine driving the shaft 2 is idling, the shaft drives the vanes 25 and the sun wheel 10, and since the carrier 14 is held against rotation by the inertia of the stationary shaft 16, the impeller 20 is caused to rotate in a reverse direction to that of the shaft 2. Since the vanes 24 will therefore rotate in the reverse direction to the vanes 25 they will have a braking effect. Increase in engine speed results in the interaction between the vanes 24-25 slowing down the impeller 20, the consequent increased torque on the gear carrier 14 overcomes the inertia of the shaft 16 and this shaft together with the runner 21 commence to rotate in the same direction as the shaft 2. After a time the ring member 18 stops, then is driven in the same direction as the shaft 2, and thereafter the transmission ratio between the shafts 2. and 16 tends to unity.

Patent GB-435864-A (GB)
Title: Improvements in the manufacture of films, threads and shaped articles
IPC: C08K5/103
Filed: 1934-03-26
Abstract: In the manufacture of films, threads, and shaped articles from solutions of plastic masses, more particularly cellulose derivatives, in organic solvents, a halogen hydrin of a polyhydric alcohol in which all the free hydroxyl groups are esterified with an aliphatic carboxylic acid containing at least 8 carbon atoms in an unbranched chain or with a naphthenic acid is employed as a softener for the plastic mass.  The carboxylic acid may be substituted in its unbranched chain by an aromatic or hydro-aromatic residue. Especially suitable for the esterification are the mixtures of fatty acids obtainable from natural, vegetable or animal fats and oils such as coconut oil, palm-nut oil or tallow.  More highly unsaturated fatty acid mixtures, e.g. as derived from linseed oil or wood oil are also suitable.  Other softeners or filling materials may also be incorporated in the plastic mass.  In an example, 300 grams of polyvinyl chloride containing 63--65 per cent of chlorine are dissolved with 60 grams of ethylene chlorhydrin naphthenate in a mixture of 350 grams of benzene and 350 grams of acetone.  The solution is filtered and cast to a film of 20 m  thickness.  Or to an ether alcohol (3 : 1) solution containing 18 per cent of nitrocellulose (12,2 per cent nitrogen) is added monochlorhydrin distearate in an amount equal to 20 per cent of the nitro-cellulose. A film of 130 m  thickness formed from the solution had double the creasing number, an improved elongation and equal strength compared with a nitro-cellulose film containing 15--20 per cent camphor.  The elongation of the film in water was about \ba1/3\be of that of a film obtainable by using a stearic acid ester of glycerine still containing a free hydroxyl group. Examples are also given of films made using as plasticizers CH2BrCHBrCH2.O.COR wherein R is the residue of coconut oil fatty acids, or monochlorhydrinerythrite tripalmitate, or a mixture of triphenyl phosphate and ethylene chlorhydrin phenylstearate.

Abstract: 464,716. Electric control systems. ELMQUIST, K. G. T. April 1, 1936, No. 3706. Convention date, April 1, 1935. [Class 40 (i)] In a distant control system, the controlled object is operated by a motor which is controlled by the induced e.m.f. in the single phase winding of the receiver of a selsyn type control system. As shown, the selsyn system comprises a transmitter 1 and receiver 5 employing single phase windings 4, 8 and interconnecting polyphase windings 2, 6. The winding 8 is connected to the grid of a rectifier 14, the anodecircuit of which is connected to the input of an amplifier 24 which controls the excitation of the field winding 28 of a motor generator 29, 30. The winding 4 of the transmitter is supplied from an A.C. source-which also is connected across a resistance 11 to provide a normal bias for the valve 14 in phase with the supply. Normally no e.m.f. is induced in winding 8 and no e.m.f. is generated by generator 29 since field 28 is neutralized by a permanently excited field 31. When the winding 2 is displaced by the handle 10, the resultant field in receiver winding 6 is displaced and an e.m.f. is induced in winding 8, the phase relationship of the e.m.f. with regard to the normal bias voltage depending upon the direction of rotation. The amplifier 24 is biassed by resistances 21, 27 so that the field 28 is strengthened or weakened relatively to the field 31 in accordance with the direction of rotation of the transmitter. Consequently the motor 32 which operates the controlled apparatus 37 is driven in one or other direction to rotate the receiver winding 6 until the voltage induced in winding 8 becomes zero. British Specifications 417,995 and 446,665 and U.S.A. Specification 1,977,624 are referred to.
