Title: Improvements in or relating to apparatus for learning to drive motor cars and for demonstrating to pedestrians
IPC: G09B9/048
Filed: 1952-09-01
Abstract: 722,952. Apparatus for training vehicle drivers. ETABLISSEMENTS PATECO. Sept. 1, 1952 [Sept. 3, 1951], No. 21967/52. Class 79(3). [Also in Groups VI and XV] Apparatus for learning to drive motor cars and for demonstrating to pedestrians comprises a model car 24 relatively stationary with respect to a road representing member 22 carrying the model, guiding rollers 33, 34 and friction discs 18, 19 bearing against the underside of the road representing member which is thereby held movable between the wheels of the car model and the guiding rollers, and driving means operatively connected to the friction discs and adapted to impart both a straight and arcuate movement to the road representing member. As shown a base plate 1 carries on its underside a rotatable pivot 3 to which a plate 5 is secured at one end, the free end of the plate 5 being conneeted to a steering wheel 43 by a cable 35 so that movement of the steering wheel correspondingly swings the. plate 5. The plate 5 carries at its free end a gear wheel 13 which is driven through gearing, a universal joint 44 and reversing gear 58, 59, 60 from a motor 61. The gear wheel 13 in turn drives a similar gear wheel 14. The friction discs 18, 19 are attached to the base plate 1, one engaging the surface of the gear wheel 13 and the other engaging the surface of the gear wheel 14. These discs project through slots in the base plate 1 and engage the underside of the road representing member 22, the top surface of which is marked to represent the road. The member 22 is supported by the guiding rollers 33, 34, which are carried respectively by arms 29, 30 and which also protrude through slots in the base plate 1. Each arm is pivotally attached by pins 31, 32 to the base plate 1 and by a pin 27 working in slots, to the plate 5 so that when the plate 5 is moved relative to the base plate 1, the guiding rollers move to take up positions so that their axes pass through one or other of the axes of the gear wheels 13, 14. Such movement of the plate 5 also moves the friction discs 18, 19 so that they are at different respective distances from the axes of their driving gear wheels 13, 14 and so are rotated at different speeds. The member 22 is thus moved by the discs 18, 19 and guided by the rollers 33, 34 either in a straight line when the discs 18, 19 are at equal distances from the axes of their respective gear wheels 13, 14 or if the distances are different, in an arc centred on one or other of the axes of the gear wheels 13, 14 so that the model motor car 24 which is attached by a flexible arm 25 to the base plate 1 and between the wheels 23 of which and the discs 18, 19 and rollers 33, 34 the member 22 is supported, moves relative to the roads marked on the member 22. The motion of the discs 18, 19 can be reversed through the reversing gear 58, 60 so that the car can apparently move in either direction.

Title: Improvements in electromagnetic interrupters
IPC: H02M7/62
Filed: 1946-07-25
Abstract: 615,118. Induction coils. AKTIEBOLAGET HAKANSSONS INDUSTRIER. July 25, 1946, No. 22188. Convention date, Aug. 1, 1945. [Class 38 (ii)] [Also in Group XXXVII] In a device specially suitable for electric fences and adapted to give periodic electric impulses at greater intervals than the natural period of oscillation of a reed, the reed maintains contacts open (or alternatively closed) while its vibrations die down only allowing them to engage (or open) when it is almost at rest. Fig. 2 shows one form wherein completion of the circuit of a primary coil 8 through contacts 2a, 3a causes the attraction of an armature 11 which, striking a bend 16 in the spring 13, gives an upward impulse to the contact 2a which breaks away from the contact 3a. The armature then returns and meets the spring 12, which has a longer natural period of vibration, preventing it from re-engaging the contact 3a and thereafter the comparatively rapid vibra-. tions of the armature maintain the contacts apart till the armature is nearly at rest when they re-engage and the cycle recommences. Each time a current impulse passes through the primary winding 8, a secondary high voltage impulse is induced in the secondary winding 7 which may be connected to a fence. In a modification, Fig. 4, armatures 11a, 11b on reed 1 and armature 27 on reed 12a are all attracted simultaneously by the magnet, but reed 12a is checked by a stop 26, causing contact separation which is maintained by the vibrations of reed 1 till these die down sufficiently.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1925-09-05
Abstract: 246,791. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Compagnie des Freins Westinghouse.). Jan. 31, 1925, [Convention date]. Fluid - pressure.- Vacuum brakes for automobiles &c. are provided with control valves in which the displacement of a diaphragm or its equivalent through a spring by a pedal or lever operated control rod effects the opening and closing of two valves controlling communication between the brake cylinder and the atmosphere and a vacuum reservoir respectively. The control pedal is connected to a rod T which displaces a diaphragm D through a spring R and a piston P enclosing the spring. The upper side of the diaphragm is open to the atmosphere through a port K' and the lower side is open to the brake cylinder. The passage C leading to the brake cylinder is normally in communication with the atmosphere through a valve S' and ports O, O<1> in the cylinder and valve casing respectively. On raising the diaphragm and piston by the rod T, the valve S' is first closed and a valve S is then raised by a stem t connecting it to the valve S<1>. The valve S opens communication between the passage A to a vacuum reservoir or pipe and the brake cylinder passage C. The downward pull of the vacuum on the diaphragm will cause the operator to feel the braking pressure, and will maintain the braking pressure determined by the pull on the rod T, as any variation in this pressure will open one or other of the valves S, S<1>, which are both closed when the parts have attained equilibrium.

Title: Improvements in and relating to the continuous distillation of coal tar
IPC: C10C1/04
Filed: 1949-08-26
Abstract: <PICT:0678933/III/1> Coal tar is continuously distilled by heating it in a continuous heater to temperatures from 335 DEG C to 350 DEG C, flashing the heated tar at an absolute pressure of between 300 and 400 mm. of mercury in a chamber into which steam is injected and fractionating the vapours in an adjoining bubble-cap column under a corresponding vacuum, the required fractions being taken off at various points in the column.  Reflux for the column is obtained from the phenol oil fraction.  As described crude tar enters at 1 and is preheated in the heat exchanger 2 by pitch from the flash chamber 20 before passing successively to heater 3, dehydrator 5, and topping column 9 for light oils operated substantially at normal pressure The light oils are condensed at 11 and reflux returned to column 9 by pipe 12.  The condensate flows through cooler 13 to separator 14 where separation of water occurs.  The topped tar is pumped through heater 17 and pressure control valve 19 to flash chamber 20, operated at 300-400 mm. pressure into which steam is introduced by pipe 21 and from which pitch flows away through exchanger 2 while steam and vapours pass into the base of fractionating column 23.  Anthracene oil is taken off as bottom product at 26, phenol oil as top product at 29 and washing and naphthalene oils as side streams at 27 and 28 respectively.  Side columns 30 and 31 are provided for the rectification of the last two fractions steam being introduced at 32 into the column 30 for distilling the lighter constituents of the washing oil while heat for the column 31 is supplied by the circulatory heater 35.  The phenol oil vapours and steam passing over at 29 are cooled at 38 and the condensate flows to a receiver 39 connected to a vacuum pump 41 and by run-off pipe 42 to separator 43 where the phenol oil and water separate.  The phenol oil is partly returned by pump 44 to the top of column 23 as reflux and partly to an auxiliary column 46 provided with circulatory heater 47 where it is completely freed from water and drawn off at 48, water vapour passing over to pipe 29.  Water from separator 43 is forced by pump 51 through evaparator 52 which feeds by pipes 54, 21 and 32 and pressure reducing valves 53 to flash column 20 and side column 30. The parts of the apparatus under reduced pressure are at a higher level than those at normal pressure and fluid columns form in the run-off pipes 24, 26, 33, 37 and 48 in accordance with the vacuum in the various columns.

Title: Improvements relating to the manufacture of moulded bodies from cellulose esters
IPC: C08J7/02
Filed: 1939-08-03
Abstract: 531,842. Treating cellulose ester articles. I. G. FARBENINDUSTRIE AKT.-GES. Aug. 3, 1939, No. 22526. Convention date, Aug. 3, 1938. [Class 2 (ii)] Thick walled moulded bodies consisting of cellulose esters and made from solutions of such esters in aliphatic chlorohydrocarbons or in solutions containing such hydrocarbons, or made by uniting several moulded bodies by means of aliphatic chlorohydrocarbons or solutions containing such chlorohydrocarbons are stabilized by treating them with a liquid which dissolves out residual aliphatic chlorohydrocarbons but has no solvent action on the cellulose ester. Methylene chloride, chloroform, ethylene chloride, ethyl chloride, propyl chloride, or tetrachlorethane alone or mixed with methyl or ethyl alcohol, acetone or benzene may be used as solvents or adhesives in the production of the moulded bodies. The cellulose esters used include cellulose triacetate, acetonesoluble cellulose acetate, cellulose propionate, and cellulose acetobutyrate. The moulded body may be dried before being treated with the extracting agent. The composition of the extracting liquid may be such that it exerts a feeble swelling effect. In an example, a cellulose triacetate film is obtained by casting from a solution containing methylene chloride, and a tube is made by winding the film and securing the layers by means of a solution of cellulose triacetate. The tube is subjected to drying conditions for several days and then the residual solvent is removed by immersing the tube in a mixture of acetone and methyl alcohol. The tube is then subjected to intense drying while supported on a rod. In another example a tube is made by extruding a cellulose triacetate solution containing methylene chloride through an annular orifice and setting by cooling to 0‹C. or lower. After drying the tube is treated with a mixture of acetone and methyl alcohol. In another example, a cellulose acetate plate containing residual methylene chloride is treated with a mixture of acetone and methyl alcohol.
