Abstract: 1323813 Spring brake actuators BENDIX CORP 5 May 1971 [18 May 1970] 13311/71 Headings F2E and F2F In a spring brake actuator fluid pressure acts through a port 64 on a piston 46 to compress spring washers 40 through a sleeve member 34 reversibly threaded to a rod 52, service actuation of the brake taking place by means of fluid pressure acting on a piston 22 by way of a port 66 on the interiors of members 34 and the rod 52, the spring washers 40, member 34 and rod 52 being located in the same chamber 14. If the vehicle fluid pressure system fails, spring washers 40 cause pads 21 to be applied to a disc through member 34 causing an enlarged portion 56 of rod 52 to engage a bearing surface on piston 22 to lock the brakes. To release the lock a nut 50 on piston 46 is rotated thereby rotating member 34, frictional engagement between a bearing surface 58 on piston 22 with portion 56 keeping rod 52 from turning so that rod 52 is retracted. In a further embodiment the rod (152) is extended and provided with a hexagonal nut (176) rotated so that rod (152) is also rotated so that portion (156) is moved away from bearing surfaces (158) on piston (122) permitting the latter to retract.

Title: Dicarnitine dichloride and a process for the preparation thereof
Filed: 1954-03-07
Abstract: The invention comprises the b -hydroxy-g -trimethylammonium chloride butyrate of b -hydroxy-g -trimethylammonium chloride butyric acid (dicarnitine dichloride) of the formula <FORM:0754873/IV(a)/1> and a process for the preparation thereof by dissolving b -hydroxy-g -trimethylammoniumchloridebutyronitrile in concentrated hydrochloric acid, e.g. with approximately twice its weight of concentrated hydrochloric acid, and heating the resulting solution under pressure, e.g. at a temperature between 100 DEG  and 140 DEG  C. for several hours.  The desired product may be isolated from the reaction product after removing ammonium chloride by fractional crystallization, or insoluble ammonium chloride may be separated from the dicarnitine dichloride solution by cooling and a first fraction of the dichloride is recovered from the acid solution by concentrating the solution in vacuo, the resulting crystals are treated with a mixture of hydrophilic solvents one of which is a solubilizing agent and the other a precipitating agent for the dichloride and the mother liquor is separated from the undissolved dicarnitine dichloride, or the mother liquid obtained after recovering the first fraction of the dichloride referred to above may be evaporated in vacuo, the residue taken up in concentrated hydrochloric acid, purified by means of activated charcoal in an aqueous medium and evaporated in vacuo, the crystals thus obtained are then treated with a mixture of the hydrophilic solvents as above to form a second fraction of dicarnitine dichloride.  Anhydrous methanol may be used as the solubilizing agent and anhydrous acetone as the precipitating agent for the mixture of hydrophilic solvents.  The ratio by volume of solibilizing agent to precipitating agent is preferably lower than 1 in 5-particularly in the neighbourhood of 1 in 10. An alternative method given for the preparation of dicarnitine dichloride is by reacting g -chloro-b -hydroxybutyronitrile and trimethylamine under pressure in alcoholic solution to form g -trimethylammoniumchloride-b -hydroxybutyrocyanide which is then treated as above.  A detailed example is given.

Title: Improvements relating to electrical contacts
IPC: H03K17/54
Filed: 1922-05-16
Abstract: 201,299. Bolitho, J. B. May 16, 1922. Relays.-For the prevention of bad contacts in relays and other electrical instruments, an oscillatory electromotive force generated by a thermionic valve is applied to the contacts when they are open, and is removed or diminished by their closure. The Figure shows a relay a controlling the position of a tongua b adapted to make contact with butts c, d or to lie in a central open position. An oscillating valve k with coupled grid and plate circuits m, k has its filament connected to the tongue b and its plate connected in parallel through condensers q, r to the butts c, d. When the tongue is central, the valve oscillates and applies a high-frequency potential between the tongue and each butt. Closure of the contact on either side puts the condenser q or r into series with the battery by-pass condenser s across the condenser l, so de-tuning the plate circuit and stopping the oscillation. Alternatively, the grid circuit may be thrown out of tune, or a damping resistance introduced in one of the circuits. In a modification, a separate oscillatory circuit is coupled to the plate coil k and is connected to the contacts. It is thrown out of tune when the contacts are closed, so that, although the valve continues to oscillate, the current passing the contacts is insufficient to affect the relay circuits e, f. g. A choke coil u may be used to exclude oscillatory currents from the relay circuits.

[Also in Group XXXVII] In a low-frequency generating system particularly for providing a supply for inching a synchronous motor, three similar D.C. machines driven by common source IM have one armature A star connected to armatures B, C to give a three-phase output to motor SM. Armature A feeds (a) shunt field winding SF1 controlled by coupled regular Rhl; and (b) windings CF2, CF3 through CRh2. Windings SF2, SF3 are series connected with RH3 between armatures B, C at 12, 10, and similarly with CF1 and CRh 1. Frequency control windings FF2, FF3 form a closed loop with coupled regulator FA2, and similarly FF1 with FA1. Due to the interconnection of the field windings, a low-frequency oscillation is maintained in the circuit and fed to the motor SM through switch S2. For large outputs, the machines may function as exciters to three star-connected main generators.

Filed: 1929-05-04
Abstract: 336,234. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 4, 1929. Motor spirit.-By subjecting olefines or gases containing olefines to a thermal treatment wherein the initial material is brought into contact with free elementary silicon or a substance containing it, for example, ferrosilicon containing a large proportion of free silicon, products containing higher olefines and aromatic hydrocarbons are obtained, which are useful as anti-knock agents for motor fuels, and as fuels. Temperatures between 350‹ and 800‹ C., and pressures from I to 1000 atmospheres or more may be employed. the higher temperatures and pressures and lower gas velocities favouring the production of increased proportions of aromatic hydrocarbons in the products. The silicon is used in the form of small pieces, or of bricks pressed from silicon powder. Suitable starting materials are ethylene. propylene, butylene or gas mixtures containing them, gases containing olefines obtained by cracking mineral oils, tar oils and the like, and casinghead olefines. Gases containing ethylene obtained by heating bituminous coal for a very short time to a red heat and rapidly cooling the resulting gas and the coke may be used, and in this case the products obtained include liquid hydrocarbons containing benzene and toluene, also butylene and butadiene, and some methane and ethane. Specifications 296,752, 301,775, and 316,422, [all in Class 2 (iii), Dyes &c.], are referred to.
