Title: Improvements in and relating to the spring suspension of vehicles
IPC: B60G17/027
Filed: 1929-12-10
Abstract: 350,421. Force-feed lubricating. NAYLOR, E. J., Thuya Cottage, Harefield Road, Uxbridge, Middlesex. Dec. 10, 1929, No. 37897. [Class 12 (iii).] In a road-vehicle suspension system, auxiliary helical springs of different strengths arranged in series are brought into action successively by hydraulic means controlled by the driver and actuated by the play of the vehicle on the main springs or by an engine or hand or foot-operated pump. In the construction shown in the Figure, a tubular member 9 connected to the axle slides vertically under the control of the auxiliary composite spring 2 in a casing 4 connected to the vehicle frame. The sleeve 1 forms a cylinder into which oil is fed so as to load the spring 2. Initial tension of the spring 2 is adjusted by vertical movement of the sleeve 1 by means of its upwardly screwed extension 5. A reciprocating plunger 7 operated by the relative movements between the axle and the vehicle frame is fixed to each casing 4, with a suction connection 15 from a storage tank, and a delivery 10. Oil is led from the delivery 10 to the cylinder 1 by a pipe, not shown, and an axial bore in the screwed extension 5. A spring 8 provides a resilient connection between the plunger 7 and the pumpoperating member 9<1> connected to the axle. One such device may be provided for each wheel of a motor vehicle, the cylinders being interconnected, and adjustable relief valves, one for each pair of wheels, controlled by the driver, may be provided. For starting with a heavy load, a further small pump could be added operating on the subsidiary springing, and low-pressure connections may be taken off each pump to facilitate automatic lubrication throughout the chassis. Surplus oil from the control devices is returned to the tank and may also be used to lubricate pedal bearings, clutch race, &c. Control by the driver may be supplemented by governor-operated release valves and the oil pump may be arranged to deliver oil only when the wheels are making maximum deflection. The hydraulic control apparatus may be applied to the screw spring suspension units described in Specification 348,667, [Group XXXII], in which a sleeve which is raised and lowered by a differential screw action acts on a subsidiarv spring. In one modification the pump is arranged below and in line with the auxiliary spring suspension, and in a further modification the pump is arranged inside a differential screw mechanism with various concentric and axial springs described in the above-mentioned Specification.

Title: Process for the preparation of phenazine derivatives
Inventor: CROSS BARRINGTON
IPC: C07D241/52
Filed: 1966-08-26
Abstract: Phenazine derivatives of the formula <FORM:1091618/C2/1> and their N-oxides, wherein R represents a halogen atom, or an alkyl, aryl, aralkyl, alkaryl, alkoxy, thioalkyl, alkysulphonyl, arylsulphonyl, hydroxy, cyano, amino, substituted amino or nitro group and m and n each represent 0, 1, 2, 3 or 4, the groups R being the same or different when m + n are greater than 1, are obtained by cyclizing a 2-nitrodiphenylamine of the formula <FORM:1091618/C2/2> by treatment with a base in an organic solvent or with oleum, and optionally converting the product, if an N-oxide, into the corresponding free phenazine base.  When effecting the cyclization by employing a base, which may be inorganic, e.g. calcium oxide or an alkali metal hydroxide, or organic, e.g. potassium t-butoxide, the reaction is suitably effected by refluxing a mixture of the diphenylamine and the base in an organic solvent having a boiling point of 130 DEG  C. or above, e.g. xylene, cumene, tetralin, naphthalene, chlorobenzene, o-dichlorobenzene or decalin.  The reaction employing oleum may suitably be effected at room temperature employing a molar ratio of sulphur trioxide in the oleum to the diphenylamine of at least 5 : 1 and the N-oxide product may be converted to the free phenazine base by heating (suitably at 180 DEG  C.) or by reduction with a metallic reducing agent.

Title: Improvements in or relating to processes for the production of monocrystalline layers of semiconductor materials
IPC: C30B25/08
Filed: 1963-10-03
Abstract: A process for producing monocrystalline layers of unspecified semi-conductor material comprises depositing the material from the gaseous phase, e.g. from a halide, on to a plurality of heated monocrystalline discs 9 of the semi-conductor material in a reaction vessel 1 divided by a substantially horizontal partition 2 into a reaction chamber 3 and a heating chamber 4 containing a heating element 5 for heating the discs 9.  The partition 2 may be of semi-conductor material the same as is to be deposited or may be of SiC, BeO, Al2O3, graphite, or graphite with a covering of semi-conductor material the same as is to be deposited.  The gaseous compound of the semi-conductor material is supplied at 7 and waste gases are removed at 8.  A water-cooled metal ring 6, above a gap between the partition 2 and vessel wall, reduces diffusion of waste gases from the heating chamber to the reaction chamber.  The heating chamber may have a metal mirror reflector (not shown) to render the temperature distribution uniform. <PICT:0985371/C1/1>ALSO:<PICT:0985371/C6-C7/1> A process for producing monocrystalline layers of unspecified semi-conductor material comprises depositing the material from the gaseous phase, e.g. from a halide, on to a plurality of heated monocrystalline discs 9 of the semi-conductor material in a reaction vessel 1 divided by a substantially horizontal partition 2 into a reaction chamber 3 and a heating chamber 4 containing a heating element 5 for heating the discs 9.

A moulding press includes a platen 14, movable towards or away from a stationary platen 12 by a double-acting main cylinder 16, hydraulic stops 150, 152 including cylinders and plungers 154 o the stationary platen directed towards the movable platen, and effective against stop members 156, 158 on the movable platen when keeping the mould partially open part of the time during the moulding cycle, and being moved back when the mould is clamped closed. The stop members 156, 158 are preferably in the form of adjustable stop screws having their effective stop surfaces at 164, and also carrying a stop nut 166 the position of which is adjustable. Positive stop surfaces 162 surround the plunger 154 of the hydraulic stops 152. When the plunger 154 is projected it acts on the stop screw surface 164 before the positive stop nut 166 reaches the positive stop surface 162.

Title: Organ stop action
IPC: G10B3/10
Filed: 1930-12-30
Abstract: 364,332. Organ stop actions. COMPTON, J. H., 37, Audley Road, Ealing, London. Dec. 30, 1930, No. 39207. Addition to 258,068, [Class 88 (ii), Music &c.]. [Class 88 (ii).] Relates to organ stop-heads as in the parent Specification wherein a spring-returned stop-head (preferably having an electric lamp indicating " on " or " off ") at each actuation makes a contact which by a reversing mechanism alternately puts into and out of action a stop, ventil, &c., and consists in rendering the stop-head operable in two degrees, the first for reversing the stop-action, and the second for reversing such other stop-actions of the same group as may be in operative position. The stop-head is spring-returned to its normal position after each operation whether to the first or second degree. Pressure on the stop-head A (which carries a contact rod D) to the first degree compresses only the spring C and completes a circuit from battery H through contacts E, F to solenoid I operating reversing mechanism J which either closes the contact L rendering the stop operative through the magnetic device M, or opens the contact L breaking the circuit through the device M and rendering the stop inoperative. The lamp O is in a parallel circuit with the device M. Pressure on the stop-head A to the second degree compresses also the stronger spring W and completes a further circuit from battery H through contacts E, G to a solenoid Q which closes a set of contacts T, T1, ... The contacts T, T1, .. are respectively connected to the contacts corresponding to the contact U of the other stops forming the group, and if these contacts are standing closed so that the stops are operative, current flows through the solenoids I of these other stops back to the common battery H, thus rendering them inoperative.
