Patent GB-1482826-A (GB)
Title: Overheat protection device for a catalytic converter
IPC: F01N3/22
Filed: 1975-05-12
Abstract: 1482826 Secondary air control to I.C. exhaust conversion catalyst NISSAN MOTOR CO Ltd 12 May 1975 [11 May 1974] 19773/75 Headings B1F and B1W The invention relates to an I.C. engine in which overheating of exhaust gas conversion catalyst 16' is prevented (a) by thermo-sensing element 55 (which may alternatively be upstream of catalyst 16') above a certain temperature causing solenoid valve 40 to be energised to break the vacuum from intake manifold 12 in chamber 32 to thus allow compression spring 30 to move valve element 27 downwardly completely and hence cause all secondary air to exhaust directly to the atmosphere via conduit 20' and hence bypass catalyst 16', and (b) by element 55 above a certain higher temperature e.g. caused by misfiring or carburetor flooding, causing warning signal 54 to be energised. In the embodiment shown, element 55 operates via logic circuit 50. The degree of opening of valve 26 and hence degree of discharge of seondary air to atmosphere depends upon the degree of vacuum in manifold 12, and when solenoid valve 40 breaks the vacuum, the pressures at check valve 24 are such that no secondary air passes to catalyst 16'.

Title: Improvements relating to the control of electric traction motors
IPC: B60L9/10
Filed: 1924-08-22
Abstract: 241,660. Metropolitan-Vickers Electrical Co., Ltd., (Westinghouse Electric & Manufacturing Co.). Aug. 22, 1924. Motor-generators; motors, controlling. - In starting and accelerating a continuous -current traction motor 28, the field-winding 27 is first connected in series and afterwards connected as a separately-excited winding. The motor armature is fed by a generator 8 driven by a singlephase motor 4, the two machines constituting a motor-generator set, and comprising an exciter generator 12 and an additional exciter generator 15, the latter being only used for the separate excitation of the motor 28. The process of starting comprises a preliminary stage in which the generator 8 runs as a motor on current from a battery 22, and is accelerated by field regulations up to the synchronous speed of the motor 4, which then receives alternating-current from a transformer 21 and takes up the drive, the machine 8 being disconnected from the battery and connected to the working motor 28 and its field 27 in series. Further field regulation of the machine 8 increases the impressed voltage on the motor 28 and accelerates it up to a point at which the field 27 is automatically changed to the separately excited condition, taking current from the exciter generator 15. Additional steps of field regulation by a subdivided resistance 37 bring the working motor to full speed. Regenerative braking takes place whenever the vehicle speed becomes excessive, providing the motor is in its separately excited condition.

Title: Improvements in or relating to the preparation of stabilized free radicals
IPC: B01J19/08
Filed: 1965-05-11
Abstract: Cellular polystyrene containing free radicals is produced by freezing a solution of polystyrene in benzene at -196 DEG  C., and irradiating by gamma rays at that temperature.  It is then heated to -70 DEG  C. and rendered lyophilic at this temperature, and finally desorbed at +30 DEG  C., and sealed under an inert gas, e.g. nitrogen.ALSO:l-Lysine containing stabilized free radicals is produced by freezing a solution of l-lysine in water or liquid ammonia with liquid nitrogen at - 196 DEG  C., and irradiating at that temperature. It is then rendered dyophilic at - 110 DEG  C. to - 30 DEG  C., then slowly desorbed at ambient temperatures and sealed under an inert gas, e.g. nitrogen.ALSO:Stabilised free radicals are formed by irradiating a free-radicals generating substance diluted with a liquid medium frozen at a temperature at which said free radicals cannot spontaneously recombine, removing the frozen liquid medium by selective sublimation at a temperature at which the said free radicals cannot spontaneously recombine, thereby providing a residual porous mass containing said free radicals, and allowing the temperature of said residual porous mass to rise to ambient temperature in the absence of air.  Exemplified free radicals are formed from 2-lysine and polystyrene.  The free radicals generated may be of different kinds, and in this case a partial reheating of the frozen material may be effected to a temperature at which only one type of free radical remains stable.

Title: Improvements in or relating to the manufacture of expanded thermoplastic materials
IPC: C08J9/12
Filed: 1946-07-04
Abstract: Expanded thermoplastic materials are prepared by heating the material to a temperature sufficient to render it plastic, impregnating with a gas under pressure without the aid of a plasticiser, cooling the material while it is still under substantial pressure, releasing the external gas pressure when cool and subsequently heating again under conditions which do not allow substantial escape of gas and allowing the material to expand on reaching a soft state.  The thermoplastic materials are rigid at room temperatures and soften with heating, those specified being polystyrene, polyethylene, polymethyl methacrylate, and lightly plasticised cellulose acetate and other esters and cellulose ethers.  The expansion step may be carried out in a mould, or under gas pressure, or between platens of a heated press, the pressure being suddenly released.  Specified gases are nitrogen, air and carbon dioxide.  For thin-walled articles, the after heating to expand can be carried out in the absence of pressure.  For sheets, the top and bottom platens of a heated press may be used for the expansion step.  In examples II and III, cellulose acetate with dimethyl phthalate, methyl ethyl ketone and alcohol is expanded.  Specifications 527,951 and 578,513 are referred to.ALSO:Expanded thermoplastic materials are prepared by heating the material to a temperature sufficient to render it plastic, impregnating with a gas under pressure without the aid of a plasticizer, coating the material while it is still under pressure, releasing the pressure when cool, and subsequently heating again under conditions which do not allow substantial escape of the gas, then allowing the material to expand on reaching a soft state.

Title: Improvements in or relating to the photographic recording of acoustic or the like oscillations
IPC: G11B7/00
Filed: 1928-07-14
Abstract: 318,709. Gramophone Co., Ltd., and Whitaker, A. July 14, 1928. Optical apparatus.-Relates to the photographic recording of acoustic or like oscillations. According to the invention, a glow-discharge tube is used, to the electrodes of which two sets of electrical oscillations are applied, one set being of substantially constant amplitude and frequency, and the other set corresponding in wave form to the sound or like oscillations in accordance with which the light intensity is to be varied. By this means, the light emitted by the gas in the region of the two electrodes, taken separately, is varied in accordance with the oscillations to be recorded, and two separate records may thus be made simultaneously, if desired. The oscillations of constant frequency and amplitude have preferably a frequency above audibility, but they may have an audible frequency to which the apparatus as a whole is not sensitive. Fig. 7 shows a circuit for carrying the invention into effect. High-frequency oscillations are applied through a transformer d to the electrodes of a discharge tube g, and low-frequency oscillations are superposed thereon through a transformer e, a condenser f and a high-frequency choke coil h being arranged as shown.
