Filed: 1928-12-27
Abstract: 303,165. Barrett Co., (Assignees of Miller, S. P.). Dec. 29, 1927, [Convention date]. Condensing processes; pitch.-Three collector mains 3, 4, 5, are provided in coke oven or gas retort plant, valves 6, 7, 8, connecting each uptake 2 with any one of the mains. Ammonia liquor is sprayed into the uptakes through nozzles 18 and into the mains through nozzles 19. Tar condensing in each of the mains flows out to separate decanting tanks for removing ammonia liquor and is then pumped to one of three stills 32 which may also receive tar from condensers through which the gases pass after leaving the collector mains. A number of uptakes 48 open into the stills so that gas from a variable number of ovens can be intro. duced. The gas and oil vapour resulting from the distillation pass out through a pipe 55 to condensers. By collecting the gases from independently regulated early, intermediate or late periods of distillation in the respective mains, tars of low, intermediate or 'high free carbon content are obtained and these are separately distilled to provide the appropriate pitches and oils. Further, by employing the total gases from a selected number of ovens for distilling the respective tars, instead of utilizing gas at the appropriate stage of distillation of the fuel, the carbon content of the resulting pitches may be modified. The pitch obtained from the intermediate carbon tar may be blended with such tar or with tar of high or low carbon content. Specifications 289,378, 303,163 and 303,164 are referred to.

Abstract: 1476517 Fluid oscillators MESSERSCHMITTBOLKOW-BLOHM GmbH 2 Sept 1974 [26 Sept 1973] 38335/74 Heading G3H In a bi-stable fluidic switch-oscillator device, Fig. 1, having a main jet supply E, outlets A 1 , A2 and feedback conduits R 1 , R 2  communicating with control inlets S 1 , S 2 , flow through the feedback conduits can be prevented by magneticallyactuated valve means. With the valve means de-energized the device functions in the manner of a conventional oscillator, the closure member 3 of the valve means being forced back and forth by the alternating feedback flows. However, by alternately energizing magnets M 1  and M2 via switch 7 the main jet can be controllably switched between the outlets. Valves 10 communicating with the atmosphere or a pressure medium tank, prevent low suction pressures developing at the control inlets. Fluid capacitors C 1 , C 2  ensure that the switch-over time of the oscillator is sufficient for the closure member 3 to move between its alternative positions. In an alternative embodiment, Figs. 2 and 3 (not shown), each feedback conduit is provided with a respective magnetically-actuated spring-biased valve (V) which functions as a non- return valve when the oscillator functions in conventional manner with the valves de-energized.

Title: Battery charging systems for road vehicles
IPC: H02J7/24
Filed: 1970-08-08
Abstract: 1349933 Charging batteries JOSEPH LUCAS (INDUSTRIES) Ltd 16 July 1971 [8 Aug 1970] 38347/70 Heading H2H An electrical system for a road vehicle comprises an alternator 12, having a wound field winding 21, the alternator being arranged to charge the vehicle battery 11 by way of a full-wave rectifier 13, the system being provided with means whereby the field winding 21 is energized only when the battery voltage is below a predetermined value. The field winding 21 is energized by way of three thyristors 14, 15, 16 which are connected to the phase points of the alternator 12, gating signals being applied to the thyristors by a circuit sensitive to the battery voltage. Resistors 24, 25 are connected across the battery 11 such that when the battery voltage is below a predetermined value a Zener diode 26 is non-conductive and hence a transistor 27 is non-conductive. Gate current thus flows through a resistor 31 to the gates of the thyristors thereby causing the field winding 21 to be energized. When a predetermined voltage is reached the Zener diode 26 conducts, the transistor 27 then becoming conductive, thus removing the gate current from the thyristors to de-energize the field winding 21. A capacitor 29 is connected to the base of the transistor 27 to render the transistor unsusceptible to transients and resistors 35, 36, 37 are provided to minimize the difference in gate cathode voltages required to fire the thyristors. A resistor 38 is provided to provide energization of the field winding 21 at starting when the ignition switch 22 is closed and resistors 17, 18, 19 are provided to minimize the risk of the thyristors being turned on by transients.

Title: Improvements in or relating to the manufacture of sheets or films of compositions containing cellulose esters or ethers
IPC: B29C71/00
Filed: 1930-12-22
Abstract: <PICT:0369610/IV/1> When making films or sheets of cellulose esters or ethers, the films after subjection to a maturing treatment with water vapour at a raised temperature according to the process of the parent Specification, are wound in a space which is maintained at a temperature considerably below the maturing temperature.  Thus, if the latter is 100 DEG  F., a convenient temperature for winding is 40 DEG  F. lower; or the cooling may be in stages, first by winding at a temperature 15 DEG  F. lower, and then rewinding with a further fall of 25 DEG  F.  By cooling during winding, it is found that the tendency of adjacent convolutions to adhere and the resulting generation of an electrostatic charge on parting, are obviated.  A convenient winding device comprises a trough 2 provided with a jacket through which, or through pipes in which, cooling water flows, and with a double cover 4 not provided with cooling means so as to avoid the deposit of condensed liquid which might fall as drops on to the film; slots 5 in the end walls of trough serve to accommodate the winding spindle 6, and a cock 10 is provided for drainage.
