Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M1/00
Filed: 1922-05-31
Abstract: 181,021. Durio, A. June 1, 1921, [Convention date]. Spray carburettors. - At starting, the float-needle valve is opened to flood the carburettor by an electromagnet energized by closing a switch within reach of the driver. The head of the needle valve 5 is provided with a piece of magnetic material 7 arranged in line with the core 4 of an electromagnet 3 having a winding 8 leading to the switch near the driver. In a modification where the fuel-valve closes upwardly, a lever of magnetic material is interposed between the core and the head of the valve. The device may act on the knob usually employed to open the valve. The electric circuit may include the engine mass or may be insulated, and the magnet may be of horseshoe form.

Abstract: 544,659. Photographic paper. KODAK, Ltd. (Eastman Kodak Co.). Oct. 21, 1940, No. 15525. [Class 98 (ii)] A paper sheet for use in photography has a coating of a dispersion of barium sulphate in polyvinyl alcohol. The paper sheet may then be coated with a silver halide emulsion in a binder such as gelatine or the hydrolysed organic esters of cellulose, for example cellulose acetate, cellulose acetate propionate, and cellulose acetate butyrate, and polyvinyl alcohol, and the emulsion may contain a sensitizing dye. The dispersion may be prepared by incorporating barium sulphate into a water solution of polyvinyl alcohol containing a plasticizer, and may be applied in one or more coats.

Title: Improvements in and relating to electric measuring instruments
IPC: G01R11/60
Filed: 1939-05-25
Abstract: 529,226. Current measurements. BRITISH THOMSON-HOUSTON CO., Ltd. May 25. 1939, No. 15550. Convention date, May 28, 1938. [Class 37] A peak current demand meter comprisesan electromagnet 12 energized from a current transformer 15 and having an armature 13 which is fixed on a pivoted shaft 14 and retracted against an adjustable stop 20 by a. spring 32 when the electromagnet 12 is de-energized. The armature 13 operates a pawl 21 engaging a ratchet-wheel 22 which, through a gear train 24, 26, 28, 29, moves a pointer 30 in the forward direction and at the same time tensions the spring 32, the outer end of which is attached to a gear-wheel 31. A pawl 35 prevents backward rotation of the ratchet-wheel 22. The gear-wheel 31 has a pin 34 arranged to strike a stop 34a in the position where the tension of the spring 32 is only sufficient to raise the armature 13 to the stop 20 when the electromagnet 12 is deenergized, the pointer 30 then being in the zero position. The coil of the electromagnet 12 is short-circuited by a pair of contacts 40 as the ratchet-wheel 22 is advanced by one tooth. When the electromagnet 12 is energized the pointer 30 is advanced and the spring 32 tensioned until the electromagnet 12 is unable to attract the armature 13. On the occurrence of a higher current, the pointer 30 is advanced further and the spring 32 adjusted to a new tension. At the end of a period the pointer 30 may be reset to zero by temporarily demeshing one pair of gear-wheels by sliding the shaft axially against a spring. In a modification the distance of the armature 13 from the electromagnet 12 is increased by means of a cam as the deflection is increased, a.spring exerting a constant retracting force. Alternatively a variable spring may be employed in addition to the cam:

Title: Polymerization of haloacrylic acid compounds
IPC: C08F20/62
Filed: 1946-05-23
Abstract: Colourless transparent polymers suitable for optical uses are produced by polymerization of monomeric a -halogen acrylic acid compounds in the presence of 0.1-5 per cent of the monomer of a neutral ester of an alcohol with an inorganic acid, soluble in the monomer and which reacts with any oxalyl halide compounds present or which may be formed during or after polymerization to yield colourless products.  Specified neutral esters are diethyl and glycol sulphates, diethyl, dipropyl, diphenyl and glycol sulphites, propyl hypochlorite, ethyl borate and ethylene and glycerine chlorohydrins and bromohydrins.  Listed a -halogen acrylic acid compounds include methyl, ethyl, propyl, butyl, phenyl, benzyl, cyclohexyl, allyl and methallyl a -chlor- and a -bromacrylates, a -chlor- and a -brom-acrylamides and the N-methyl derivatives thereof and a -chlor-acrylonitrile.  The process may be carried out by mass, solvent, granular or emulsion polymerization methods and may be promoted by use of light or other catalysts, e.g. benzoyl, succinyl peroxides, peracetic acid. Generally, polymerization is effected by heating, e.g. at 20-120 DEG  C., preferably between 35 DEG  and 65 DEG  C., and the polymer subsequently hardened by heating between 100 DEG  and 120 DEG  C. for from 8-24 hours.

Abstract: 446,044. Distributing music. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. June 4, 1935, No. 16170. Convention date, March 8. [Class 40 (iv)] In a system in which low-frequency programme matter is distributed over telephone lines, the insertion of the power supply plug of the programme amplifier V energizes a relay Re3 which cuts off the telephone set and connects the amplifier to the line 1, 2 and means are provided for disconnecting the amplifier when a telephone call is originated or received and automatically connecting it up again on the termination of the call. On the arrival of a call, ringing current, rectified at G, energizes Re2 which locks up and cuts off Re3. When the receiver is removed, whether to answer or to originate a call, Re1 pulls up over the loop and disconnects Re3, Re2. On the termination of the call, the relapse of Re1 allows Re3 to connect up the amplifier again. The system may be used for enabling the subscriber to disconnect the programme apparatus, if lie has gone out and left it connected up by mistake, by ringing his own line.

Title: Improvements in the treatment of plasticisable compounds
IPC: C08J3/18
Filed: 1936-06-10
Abstract: In the treatment of plasticizable compounds, e.g. cellulose derivatives and synthetic resins, with plasticizers, e.g. triacetin, alkyl phthalates and tartrates, sulphonamides, and alkyl and aryl phosphates, the plasticizer is distributed uniformly over the surface of particles of the compound which are moistened with a non-solvent for the compound.  The non-solvent is then removed from the mass by evaporation in the absence of any mechanical working, so that the original physical state of the compound is substantially unchanged. The non-solvent may be water, ethyl or other alcohols, isopropyl or other ethers, benzene or toluene.  The plasticizer may be added as a spray or thin stream, being run slowly on to the particles of the compound, which may be spread out in a thin layer or contained in a mixing apparatus.  Solutions of solid plasticizers in volatile solvents may be used.  Pigments, dyes and fillers may be added, e.g. before damping with the non-solvent.  Specified synthetic resins treated are polyvinyl resins and diphenylol-propane formaldehyde resins.

Abstract: 1392223 Level-luffing jib cranes HILGERS AG 10 April 1972 [8 April 1971] 16371/72 Heading B8B [Also in Division G3] A device for obtaining a horizontal load movement in a luffing jib crane comprises a cam disc 4 moved by a cord 17 from the luffing mechanism and coupled by a shaft 18 to a potentiometer 19. A circular disc 7 is similarly actuated by a cord 20 connected to the lifting mechanism and is coupled by a shaft 24 to a potentiometer 22. The potentiometers 19, 22 are connected in a bridge circuit. As long as the lifting and luffing mechanisms operate at the correct speed ratio relative to one another, the bridge circuit is in balance. If this balance is disturbed a control signal is produced at the output of the bridge circuit, which is used to control the lifting winch so as to obtain horizontal load movement. In a modification (not shown), the cam 4 is circular, the resistance of one or both potentiometers 19, 22 providing the necessary information. In a further embodiment, Figs. 2A, 2B (not shown) a control disc (7) has two conductive areas separated by a neutral, insulating gap. The disc (7) is rotated by the luffing mechanism via a cam (4) while a pointer (12) is rotated by the lifting mechanism. As long as the pointer (12) is in the gap no signal is produced, but should the pointer (12) leave the gap it encounters positive or negative voltage producing a control signal for the lifting winch. The cam 4 may be designed to rotate several times and may compensate for the resilient deformations of the crane for a medium load. A suitable set of cam discs may be provided for the lengths of jib provided.
