Title: Improvements in or relating to type printing telegraph systems
IPC: H04L25/42
Filed: 1932-04-11
Abstract: 389,284. Type-printing telegraphy. MOND, A. L., 19, Southampton Buildings, London.-(Watsongraph Corporation ; 20, Pine Street, New York, U.S.A.) April 11, 1932, No. 10286. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 12, 1932.] [Class 40 (iii).] In a printing-telegraph system with synchronously rotated arms at the transmitter and receiver passing over discs with contacts corresponding to the characters, any lever of the keyboard transmitter completes on depression a charging circuit for an associated condenser and on release prepares a discharge circuit which is completed when the arm reaches the contact associated with the depressed key. With the contact 14 of the send-receive switch in the sending position, any key lever 1 on actuation completes, through contact 16, a charging circuit for the associated condenser 18, and on release prepares, at contact 21, a circuit through which the condenser 18 is discharged when the rotating arm 7 reaches the contact 6 corresponding to the actuated key lever 1. The condenser discharge operates a relay 28 closing at contact 26 the circuit of a radio-transmitter 22. Receiver. The impulses from the radioreceiver 30 are applied to two mercury-vapour valves 33 whose plate circuits are connected to alternate segments 41 of the contact disc 40, the valve which is rendered operative being determined by the position of the synchronous arm 42 when the impulse is received. Corresponding to the position of the arm 42 plate current flows from one of the valves 33 through the winding of the associated solenoid 38 attracting its key-bar 1, which actuates a link 4 and a type-bar 3 to print the character on the roll 2. If plate current is still flowing from the valve rendered operative by the impulse when the arm 42 passes on to the adjacent segment a second solenoid 38 will not be operated, since the segment is connected to the non-operative valve. To prevent damage to the apparatus on account of ultra-rapid actuation of the printing mechanism by atmospherics, a magnet 55, energized whenever a letter is printed, moves a plunger 56 to open contacts in the printing circuit just after the associated solenoid 38 has been actuated. The arm 50 controlling these contacts is returned under control of a dashpot arrangement 51, 52 within the time interval for the normal actuation of successive keys at the transmitter so that erroneous printing of letters due to atmospherics will be effected at a rate comparable with that due to normal keyboard operation, thereby reducing the risk of damage to the apparatus.

Title: Improvements in or relating to power assisted steering mechanisms
IPC: B62D5/24
Filed: 1953-04-16
Abstract: 720,888. Fluid-pressure servomotor-control systems. FORD MOTOR CO., Ltd. April 16, 1953 [April 17, 1952], No. 10462/53. Class 135. A power-assisted steering mechanism includes an hydraulic servo unit controlled by a device incorporated in.the steering mechanism housing and directly actuated by a member which is actuated in its turn by the torsional deflection of the steering post when under load. Under light load, the pitman arm is actuated directly through the steering wheel 21, steering post 18, worm 17, and a worm wheel 16 carried on a rotary shaft 12 to which the pitman arm is attached. The steering post is surrounded by a sleeve 42 which is rigid with the post adjacent the steering wheel, but is free at its lower end. A pin 48 passes through a longitudinal slot in the steering post and through diametrically opposed oblique slots in the sleeve 42, and the ends of the pin are attached to a sliding spool valve 76 located in a fixed, ported sleeve 53. In the neutral position of the valve in its sleeve, the central land of the spool does not quite lap the inlet port leading from a pump 71 and pressure fluid flows to both ends of a piston. and-cylinder servomotor 22. If any resistance is encountered when the steering wheel 21 is turned, the steering post, due to a reduced intermediate portion 41, twists at its lower end relatively to the sleeve 42 and the pin 48 will be moved longitudinally, along with valve 76, and so cause actuation of the servomotor 22. The latter is connected to the shaft 12 and, as that shaft turns, the steering post along with the valve will return to neutral position. The steering post carries lugs which engage with some lost motion in grooves 87 in the sleeve 42 so that, should the servomotor not respond to the control, the edges of the grooves will engage the lugs and the pitman arm will be turned directly.

Title: Improvements relating to the refining of naptha produced by the distillation of coaltar
IPC: C10C1/20
Filed: 1947-04-24
Abstract: Coal tar naphtha which has been washed with strong sulphuric acid, is freed from acid-tar by sedimentation, agitated with aqueous alkali at a temperature between 90 DEG  and 200 DEG  C., and distilled.  The hot alkali treatment, which may be carried out by boiling the naphtha and alkali together under a reflux condenser or by heating them together with agitation in a closed vessel under pressure, enables a distillate to be obtained having an acidity less than one-third of that given when cold alkali washing is employed.  The treatment is preferably effected by agitating the naphtha with a solution of caustic soda, the amount of caustic soda being at least 0.3 per cent w : v of the naphtha, in a closed vessel at a temperature between 130 DEG  and 200 DEG  C.  In an example, a naphtha fraction boiling between 100 DEG  and 200 DEG  C. was freed from tar acid and bases, and then agitated with 3 per cent by volume of 94.4 per cent sulphuric acid for 65 minutes at 40 DEG  C.  The mixture was allowed to settle for 15 minutes, as much acid-tar as possible was run off and the rest was, as far as possible, washed out with 20 per cent by volume of water.  The oil was refluxed for 1 hour with 5 per cent by volume of a 50 per cent solution of caustic soda, and then distilled. The distillate had zero acidity.  In another example, a naphtha fraction distilling up to 200 DEG  C. was washed with 3 per cent of 94.6 per cent sulphuric acid for one hour at 40 DEG  C.  The acid-tar was separated and the oil washed twice with 20 per cent by volume of water.  A portion of the oil was heated for one hour with 30 per cent by volume of a 2 per cent caustic soda solution under a pressure of 90 lbs. per square inch (about 146 DEG  C.), and then distilled.  The acidity of the distillate was about one-ninth of the distillate obtained from another portion of the acid-washed oil which was treated in the normal way, i.e. washed first with cold caustic soda solution and then with water until the water was neutral on leaving the oil.

Title: Alder extracts for pharmaceutical use
Inventor: LAFON VICTOR
IPC: A61K36/00
Filed: 1962-03-22
Abstract: Alder extracts having hypercholeretic properties are prepared by macerating alder bark and/or leaves of Alnus glutinosa, Alnus viridis, Alnus cordata or Alnus incana for 5 to 15 hours with water at a temperature of 30 DEG  to 50 DEG C., the proportion by weight of water to the plant being between 5 : 1 and 12 : 1, and concentrating the resultant solution after separation from the bark and/or leaf residue.  Several macerating steps may be carried out and the resultant solutions may be filtered, heated, filtered again and concentrated under vacuum, the heating step being effected by boiling for 20 to 60 minutes or heating under pressure at about 120 DEG C. for 8 to 15 minutes.  Alternatively, instead of heating, the filtered solutions resulting from maceration may be admixed with alcohol before being filtered again and concentrated.  The concentrated solution obtained may be spray-dried, preferably at a temperature from ambient up to 50 DEG C., to yield a fine, dark maroon-coloured powder having an aromatic smell and a bitter taste.  For application, the extract is admixed with a pharmaceutical carrier and, optionally, an emulsifier for cholesterol having the formula HO-(C2H4O)a-(C3H6O) b-(C2H4O)c-H in which a has a value between 25 and 31 and b + c a value between 130 and 170, the emulsifier preferably having a molecular weight of 7500 to 8500. The alder extract may be administered orally in the form of an aqueous solution containing also the above-mentioned cholesterol emulsifier, sorbitol and flavouring and colouring agents.
