Title: Modified styrene-linseed oil interpolymers
IPC: C09D125/14
Filed: 1949-01-25
Abstract: Resins soluble in aromatic solvents are prepared by polymerizing in an inert solvent, at elevated temperatures, one part by weight of linseed oil with between 0.5 and 1.2 parts of a mixture of alkenyl aromatic hydrocarbons having from 8 to 10 carbon atoms in the molecule and comprising a major proportion of styrene, divinylbenzene, and 0-35 per cent of an a -alkylated styrene, the solvent constituting 20-60 per cent by weight of the solution.  The percentage of divinylbenzene in the alkenyl compounds is from 2+0.031 A to 4-0.026 A, where A is the per cent by weight of a -alkylated styrene in the mixture of alkenyl aromatic compounds.  Specified a -alkylated styrenes are a  - methyl styrene and b -methyl a -methyl styrene and, as other alkenyl aromatic compounds, vinyl toluene and ethyl vinyl benzene.  Suitable solvents are toluene, xylene, mesitylene, ethyl and diethyl benzene, chlorobenzene, o-dichlorobenzene, mineral spirits and liquids rich in aromatic compounds.  Minor amounts of peroxide catalysts may be present. Polymerization is preferably effected in a closed vessel or with the solution in contact with an inert gas, generally at temperatures of from 100-200 DEG  C., until at least 80 per cent of the alkenyl aromatic compounds are polymerized and a 50 per cent solution has a Gardner-Holdt viscosity greater than B.  The products are clear and transparent and may be dissolved in the usual varnish solvents, preferably in a mixture of 1 part of an aromatic solvent and between 0.75 and 1.25 parts of mineral spirits.  Usual additives, e.g. resins (including rosin), drying oils, driers, dyes and pigments, may be added.  The varnish films may be hardened rapidly (1 to 3 hours) by heating at 120 DEG  C.

Title: Improvements in or relating to colliery and like overwind gear
IPC: B66B5/08
Filed: 1941-02-19
Abstract: 543,475. Colliery gear control. HEWITT, H. Feb. 19, 1941, No. 2264. [Class 78 (v)] In colliery and like overwind gear for automatically controlling the engine and/or applying the brakes, of the type in which the power unit drives a pump to force fluid through a pressure system which is controlled by a valve operated by a cam driven from the engine and timed therewith, the engine speed is regulated before the usual stopping means is actuated. To this end a second pressure-control system is combined with the stopping pressure-control system. When the wind is taking place the cam 4 causes a sleeve valve 11 to move thrcugh parallel motion linkage, 3a, 20, 21, 22 to keep ports therein open respectively to exhaust, inlet, and feed. Pressure from a reservoir 1 is admitted by way of control valve 5 to a cylinder 6, and the piston therein moves u or down according to the rise and fall of the pressure, due to the higher speed of the engine at the middle of the wind and the lower speeds at beginning and end. An inner piston in the valve sleeve moving in valve, 11 is actuated by parallel link motion 6a, 23, 24 from the piston of cylinder 6 to shadow the movement of the sleeve under normal conditions. If the engine speed for any particular position is abnormal, however, the valve 11 will admit fluid pressure to a brake- and throttle-actuating cylinder 8. When the engine speed returns to normal the fluid will be exhausted from cylinder 8. Lever 23 is adjustably connected to piston rod 6a, so that a close control can be attained.

Title: Coil loaded circuit

Abstract: 546,393. Loading. STANDARD TELEPHONES & CABLES, Ltd. Feb. 21, 1941, No. 2374. Convention date, Feb. 24, 1940. Drawings to Specification. [Class 40 (iv)] In the design of a lump-loaded line, a particular coil size and spacing to give a desired characteristic impedance and cut-off frequency are arrived at in known manner on the assumption that the loading coils have no self-capacity. The measured self-capacity of a coil is first considered to be equivalent to lumped capacities at each side of the coil and these are then considered to be due to additional lengths of the kind of cable used which would have equal capacities and the spacing previously arrived at is thus considered to be too great by these lengths. At the same time the coils are considered to have been reduced in inductance by the inductances of these imaginary additional lengths, and thus to be too small by these values. Larger coils or closer spacing or both are therefore used in the final design.

[Also in Division G1] In an electrical speed-sensing device for a vehicle comprising a rotatable drive transmission (e.g. a road wheel, a differential gear, or a propeller shaft coupling) or a braking member 7 (e.g. a brake disc or a brake drum) of the vehicle and an inductive transducer 1, associated with the transmission or braking member 7, the member being of ferromagnetic material and having a series of interruptions 8 disposed around the axis of the member and arranged to pass during rotation of the member successively adjacent the transducer to cause a periodic fluctuation in the electromagnetic reluctance thereof such that means associated with the transducer is provided to sense the frequency of a signal generated thereby as a result of the periodic fluctuation. The signal generated can be adapted to release an associated wheel brake whenever a certain level of deceleration of a vehicle wheel is reached. The inductive transducer 1 is in the form of a permanent magnet core around which solenoid coils 3 and 4 are wound, the signals picked up by the polepieces when the member 7 rotates set up a corresponding alternating current in the coils 3 and 4 and the transducer is connected in an electrical circuit including an amplifier 10 which produces an output signal varying periodically in amplitude at the frequency of the fluctuations in the reluctance of the magnetic circuit between the transducer 1 and the member 7. The alternating current output from the amplifier 10 is fed to a squaring circuit, thence to an integrating circuit, an amplifier 12 and to a differentiating circuit 13 which produces an output signal proportional to the rate of deceleration of the member 7. This signal is then fed to a further circuit 14 constituting a deceleration rate detector to provide an output signal to an amplifier 15 thereafter to operate a solenoid-controlled valve 16 to release the brake associated with the skidding wheel. The transducer may be mounted on the brake caliper housing of a disc brake and be associated with a strip of corrugated metal secured to the inner surface of a vehicle wheel or may be associated with a series of perforations or indentations in the material of the wheel body. As shown in Fig. 10 the transducer 74 may be mounted on a differential gear housing of a rear axle 72 of a vehicle and the gaps and the adjacent teeth 73 of the crown wheel constitute interruptions. Fig. 11 shows a further alternative embodiment wherein a ferro-magnetic disc 80 is rotatably mounted adjacent the differential gear 82 and the propeller shaft 83 of the vehicle. The disc 80 may be provided with holes, indentations or teeth.
