Title: Improvements in and relating to electric fires
Inventor: PAINTON CLAUDE ARTHUR
IPC: F24C7/00
Filed: 1961-01-16
Abstract: 926,062. Imitation solid fuel fires; doors; electric fires. March 8, 1962 [Jan. 16, 1961], No. 1734/61. Classes 39 (3) and 126. An electric fire having imitation fuel and an electric heating element has a movably mounted obturator which can be moved to and from a position in which it screens the heating element from view. A heating element 6 is mounted in a reflector directing heat through an opening 3 in the front of an electric fire below the support 1 for imitation fuel 2. A screen or door 10 can be moved to close the opening 3, the movement of the screen 10 actuating a switch in the circuit of the heating element. The reflector and heating element may form a movable assembly which is retracted from the opening 3 when the door is moved to close it. The reflector 7 has rearwardly extending arms 12 carrying wheels 14 running on rails 15 formed by the lower edges of slots in the side walls 16 of a heating element and obturator assembly, Figs. 2 and 4, which is secured below the fuel support 1. The reflector 7 is moved into its forward position by a linkage 28, 26 when a cam wheel 29 is turned by a oneway electric motor 33. The cam 29 is arranged so that, at each half revolution, a switch 39 is actuated to change the circuit of the motor. A half revolution of cam 29 moves the reflector assembly from the rearward position shown to its operative position, and the two circuits supplying the motor are controlled by separate manual switches. The links 26 are pivoted at their upper ends, and one link 26 may carry a mercury switch to prevent the heating element being energized in the rear position. The door 10 is supported on pivots 21 resting in slots 22 in the side walls 16, and is moved away from the front opening by lugs 24 on the reflector supporting carriage 12 engaging side pieces 20 attached to the door 10. It returns to place by gravity or spring action. A thermostatic switch may be provided to prevent retraction of the reflector and heating element assembly while hot, and a thermally operated latch may prevent the door closing while the element is hot. In another embodiment, Fig. 5, the door 11 and reflector assembly 9 are moved together by a push-pull rod 48 and lever arm 46. The reflector may be fixed behind the opening 3, only the door 11 being moved. A mercury switch on the door prevents the element being energized when the door is closed.

Title: Improvements in or relating to cathode ray tube signal indicator arrangements and teletransmission system incorporating the same
IPC: H04L25/04
Filed: 1946-01-18
Abstract: 610,551. Electric indicating systems. SADIR-CARPENTIER. Jan. 18, 1946, No. 1836. Convention date, March 20, 1945. [Class 40 (i)] [Also in Groups XXXVI and XL (c)] The interval between two pulses controls the amplitude of an auxiliary pulse which is applied to shock-excite a tuned circuit from which deflecting voltages or currents are derived in phase quadrature to cause a cathode-ray beam to describe a circle of radius proportional to the interval between the two pulses. Pulses A, Fig. 1, recur at regular intervals, while pulses B occur anywhere between C, D and are distinguished from pulses A, e.g. by amplitude. Pulses B are separated at 2, Fig. 2, and applied to synchronize a sawtooth oscillator 4 whose output is applied to the screen grid of valve 5. Pulses A are separated at 2 and applied to unblock valve 5 to produce a pulse whose amplitude is determined by the screen voltage and thus by the interval B1, A2, Fig. 1. This pulse is applied to shock-excite circuit 11 and the resulting oscillations are phase split, amplified at 13, 17 and applied to deflect the cathode-ray beam to trace a collapsing spiral. The anode of the cathode-ray tube is fed with an exponentially decreasing potential from 18 to convert the collapsing spiral into a circle whose radius is determined by the interval B1, A2. The cathode-ray tube anode potential is preferably derived by using the pulses A to synchronize a saw-tooth oscillator 27, Fig. 6, of the growing type, so that on cessation a voltage kick occurs in inductance 23 to charge condenser 24 over diode 25, the charge leaking off over resistance 26 adjusted to give the correct damping to maintain the circular deflection. Preferably, a further series of timemodulated pulses 6, Fig. 8, are employed, and after separation are used to unblock the circuit of the cathode-ray tube to give a spot whose distance from the centre is related to B1, A2. A transmitter for producing the pulses A, B, C may comprise delay lines whose tapping determine the location of pulses B, C.

Title: Improvements relating to the manufacture of cellular glass
IPC: C03B19/08
Filed: 1935-01-22
Abstract: 433,423. Glass manufacture. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST. GOBAIN, CHAUNY, & CIREY, 1<bis>, Place des Saussaies, Paris. Jan. 22, 1935, Nos. 2146 and 2147. Convention dates, Jan. 27, 1934 and May 2, 1934. [Class 56] A process for making articles of cellular glass consists in placing molten glass which is seedy or bubbly in a mould, and creating a partial vacuum in the mould whereby the glass is caused to swell and take the shape of the mould. The process can be carried out by means of a mould 3, Fig. 1, mounted on a platform 10 having an orifice 11 which is connected with a suction pump 14 and a vacuum tank 15. A hinged lid 4 is provided for the mould, and a bell 16 covers the mould and rests on a sealing ring 19 fixed to the platform 10. In use, the mould 3 is heated and it is then partly filled with the seedy glass, and the bell 16 is placed over the mould. A cock 13 is then turned to connect the space within the bell with the vacuum tank 15, so that a partial vacuum is created about the mould and glass is caused, by the expansion of the contained gas bubbles, to swell until it fills the mould. In another construction, the molten glass is placed in a layer 39, Fig. 3, in a shallow receptacle 38, and a mould 32 is pressed down on to the glass. Compartments in the mould are connected by a tube 35 with a suction pump, as before. The expansion of the glass can be assisted by the addition of substances such as barium sulphate, which evolve gases at high temperature when mixed with the glass. The process may be used for making blocks or plates for use as heat or sound insulators.

Patent GB-568914-A (GB)
Title: Manufacture of polyvinyl acetal resins
IPC: C08F8/28
Filed: 1943-02-11
Abstract: Polyvinyl acetals are prepared by adding with agitation polyvinyl alcohol, dissolved in a preponderantly aqueous solvent, to an aldehyde containing at least two carbon atoms, in the presence of an acid catalyst, at least 0.08 mols. of aldehyde being present per mol. of polyvinyl alcohol, in such a way that rapid dispersion of the polyvinyl alcohol is obtained, and maintaining the reaction mixture under agitation until acetalization has proceeded to the predetermined degree.  In a modification of the process, the polyvinyl alcohol solution and the aldehyde may be introduced into a reaction vessel simultaneously in proportionate amounts under vigorous agitation. The polyvinyl alcohol may be added to the aldehyde contained in a reaction vessel and, if desired, a further quantity of aldehyde may be added to the reaction mixture.  Small amounts of dispersing agents, e.g. gelatine, monomyristine, monostearine or a fatty alcohol sulphate, may be added to the polyvinyl alcohol solution. In examples: (1) a 10 per cent aqueous solution of polyvinyl alcohol containing sulphuric acid catalyst is added to butyraldehyde under agitation, a further portion of butyraldehyde is added and the mixture held at 50-55 DEG  C.; and (2) an aqueous solution containing polyvinyl alcohol, sulphuric acid and methanol and butyraldehyde are introduced simultaneously into a mixing vessel in proportionate amounts, the mixture is maintained under agitation for an hour at 50 DEG  C. when, on cooling, the polyvinyl butyral resin separates out.  Resins are obtained, having constitutions by weight of polyvinyl ester 0-10 per cent, polyvinyl alcohol 15-22 per cent and polyvinyl acetal 85-77 per cent.  Examples are given of the use of acetaldehyde, butyraldehyde, isobutyraldehyde, paraldehyde, propionaldehyde, benzaldehyde, 2.4-dimethyl pentanal, and mixtures of aldehydes.

Title: Modified water-soluble polymeric substituted acrylamides
IPC: C08F8/00
Filed: 1958-01-24
Abstract: Water-soluble copolymers containing recurring units of the N-methylglucamide of acrylic acid are obtained by reacting a copolymer of methyl acrylate and at least one monoethylenically unsaturated monomer with sufficient N-methyl-glucamine to convert from 10%-100% of the methyl acrylate units to amide units and thereby render the copolymer water-soluble, the reaction being carried out at a temperature in the range of 115 DEG -155 DEG C. in the presence of an inert organic solvent, e.g. dimethyl formamide, dimethyl sulphoxide or dioxane.  Unsaturated monomers specified are alkyl acrylates and methacrylates, acrylic acid, acrylonitrile, styrene, chlorostyrene and alkyl styrenes, vinyl ethers and sulphides, N-vinyl pyrrolidone, piperidone and oxohexamethyleneimine and alkyl derivatives thereof, vinyl sulphones and N-vinyl alkylene-ureas.  In the examples, the use is described of copolymers of methyl acrylate with methyl, ethyl and dodecyl methacrylates.  When the resulting copolymer contains unreacted methyl acrylate units, these may be hydrolysed by treatment with an alkali metal or ammonium hydroxide, or reacted with a low molecular weight amine, e.g. dimethylamine, dibutylamine, N-methyl-N-propylamine, dimethylaminopropylamine or diethylaminobutylamine.  The copolymers may be used as soil conditioners, whiteness retention agents for textiles and in applications to paper.

Abstract: 510,086. Lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and ROBERTS, W. T. B. Jan. 26, 1938, No. 2469. Addition to 470,749. [Class 17 (i)] Relates to improvements in the toe-lasting machine described in the parent Specification, modified as described in Specifications 482,275 and 489,649. To prevent the edge of the insole being lifted as the wipers perform their upwiping movement or begin their over-wiping movement, the hold down for the toe end of the insole is made larger, to extend nearer the edge of the insole. To allow room for this larger member, the inner side of the slot guiding the tacker nozzles is dispensed with, and the nozzles urged against the outer side of the slot by springs. The member is urged towards the toe end of the insole by springs, so that it can yield should the wipers engage it during their advance. The extent to which the upper spreading and retarding fingers described in the prior Specifications descend, to co-operate with the wipers during the up-wipe, can be adjusted. The plate 215, described in the prior Specifications, carries a pair of arms 11 engaging grooves between a head 15 and the sole engaging portion of the insole engaging plate 9. Blocks 23 pivoted to the plate 215 carry spring plungers 25 urging the plate 9 towards the edge of the insole, a lug 19 on one extension 17 of the plate 9 engaging a corner of the plate 23 to retain the plate 9 on its carrier. The spring plungers allow the plate 9 to yield should the wipers engage it. To allow room for the larger plate 9, the inner side of the slot in the plates guiding the tackers 3 is cut away, the tackers being urged against the edge 5 of the plates by springs (not shown). To adjust the distance that the upper spreading and retarding fingers are depressed below the insole, the link supporting them, which is resiliently depressed as described in the prior Specifications, is provided with a lug cooperating with a vertically adjustable roll, so that descent of the fingers may be prevented or limited to any desired vertical distance.
