Title: Arrangement in lighting control systems, especially stage lighting systems, for extinguishing lamps having abnormally aw rated output
IPC: H05B39/04
Filed: 1949-08-23
Abstract: 659,888. Inductive control systems for stage lighting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 23, 1949, Nos. 21839 and 21840. Convention dates, Nov. 15, 1948, and March 18, 1949. [Class 38 (iv)] A dimming control system for stage lighting in which the lamps 1 are controlled by a main series transductor 2 and which allows for extinguishing lamps of low consumption, comprises an auxiliary transductor 5 which increasingly diverts current from the lamp circuit as the current passing through the main transductor is progressively reduced to its minimum value. Transductor 2 is self-excited and has opposing D.C. windings 21, 22 co-operating in such a manner that the voltage delivered to the lamps is, within wide limits, independent of the lamp current. For this purpose the no-load current of a further transductor 3 (controlling the other two), rectified at 10 and traversing the winding 21 is compensated by D.C. applied to the winding 22 from a source 11. Rectifier 10 also supplies a winding 51 of the auxiliary transductor, which is self excited and effectively in shunt with the lamps and, if desired, in series with some turns of a transformer 12. A further winding 52 opposing winding 51 is provided and is so energized that transductor 5 takes little current when transductor 2 passes a heavy current. Control of transductor 3, which is self excited and supplied from the transformer 12, is, by a winding 31, adjustably energized from a main control potentiometer 4 over a rectifier 7 and blackout switch 17, winding 31 being opposed by a further winding 32 energized over rectifier 9 in accordance with the voltage across the lamps. To remove higher harmonics from the lamp circuit under low load conditions, a resistancecapacity filter or a non-linear resistor, such as a lamp, 15, may shunt the lamp circuit. In a modified arrangement, winding 51 is energized in accordance with the voltage across the main transductor. The shunt transductor 5 and its associated gear may be assembled as a separate unit for connection to the main transductor.

Abstract: 391,659. Revolving-barrel locks and latches. PLUSCHKE, J., 32, Calle Iturbide, Mexico City. Aug. 6, 1932, No. 22141. [Class 44.] A latch-actuating rotating- barrel lock has divided plate tumblers 24, 25 longitudinally displaced to line up with the plane of separation of the barrel end and a fixed end disc 17 in which the one set of divided plates 25 are housed and acted on by springs. The barrel 16 is housed in a cylindrical shell 15 and carries follower arms 19 projecting radially outward between the shell 15 and the end disc 17. Fig. 10 shows the barrel 16, fixed disc 17 and an enclosing cylinder 15, separated, but when assembled the parts 15, 17 are joined by screws which are engaged by stop shoulders 20 to limit the movement of the follower disc 19 which is fixed to the barrel 16 and operates the latch. Fig. 9 shows the inner end of the barrel. The key may be of angular shape in section and have a longitudinally ridged shank so that it can only be inserted in a corresponding key-slot. By the arrangement shown in Fig. 24, bolts 35 are operable by the arms of the follower disc in conjunction with the latch slide. The bolts are held both in the projected and the withdrawn positions by catches 47. When the follower disc is turned, either by the barrel or by a handle on the inside of the door, one of the disc arms engages pin 46 to move forward a slide 39 which lifts the catches 47 and moves lateral spring pawls 50 on the latch slide 33 out of the way; on further movement of the follower, the rear arm engages lug 34 to retract the latch slide 33 and this latter retracts the bolts 35 by its lugs 56, the bolts then being held withdrawn by the catches 47 engaging the recesses 48. When the door is shut the latch is automatically moved in and then out ; the first movement permits the spring pawls 50 to ride over by the catches 47, but on the return movement the catches 47 are lifted to free the bolts 35 which are spring- pressed outwards.

Title: Improvements in or relating to the hydrolysis of polymeric vinyl esters of carboxylic acids
Inventor: MAYNE JOHN EDWIN OAKLEY
IPC: C08F8/12
Filed: 1948-08-27
Abstract: Polymers or copolymers of vinyl esters of carboxylic acids are hydrolysed by heating an aqueous emulsion in the presence of an organic hydrogen sulphate or sulphonic acid, containing at least 8 carbon atoms forming at least one ring of not less than 5 carbon atoms.  Catalysts of fused ring structure such as dibutyl naphthalene, 2-naphthalene and dodecyl toluene sulphonic acids are used in an amount of 3/4 to 4 per cent by weight of ester and mineral acid may be present in a similar amount.  The reaction is reversible and the emulsion should have a pH of less than 2.5.  Volatile products, e.g. acetic acid from polyvinyl acetate, may be removed by (a) a continuous current of air or inert gas, or if the hydrolysis is in an enclosed space by (b) a solvent, e.g. methylisobutyl ketone, an ion-exchanger, dialysis, partially by direct drying or by neutralizing with sodium hydroxide.  The latter precipitates a spongy gel from which sodium acetate may be extracted by methanol, and also neutralises the catalyst.  Examples describe method (a) applied to a polyvinyl acetate emulsion containing cetyl alcohol and a partially sulphated and hydrolysed polyvinyl acetate prepared with benzoyl peroxide as a catalyst and method (b) applied to a similar emulsion containing an oleate ester of a polyethylene oxide, a partially hydrolysed polyvinyl acetate, a sodium salt of dioctyl sulphosuccinic acid, sodium bicarbonate and prepared with hydrogen peroxide as a catalyst.  Specification 627,612 is referred to.

Abstract: 836,423. Wall coverings; bricks. WESSEL, H. July 23, 1956 [July 26, 1955; July 27, 1955], No. 22727/56. Classes 20(4) and 87(1) [Also in Group XXIII] A wall, brick or breeze block is provided with a ceramic or vitreous surface layer by applying thereto two separate layers of ceramic-forming or ' vitrifiable material, the outer layer being heated to sinter or vitrify it and attach it firmly to the intermediate layer. The surface of a wall is moistened with a solution of water glass prior to plastering thereon of the first ceramic-forming layer which contains blast furnace pumice, clay and sand mixed to a paste with water glass. to which may be applied a second intermediate layer containing sand, clay and aluminous cement. After hardening, which may be assisted by heating to about 650‹C., the outer layer is applied containing quartz, borax, feldspar, sodium carbonate, kryolite, sodium nitrate and barium carbonate. Metallic oxides may be added to colour the outer layer which is heated to vitrifying temperature by a transportable heater 3, Fig. 2, comprising electric heater elements 5 backed by a refractory block 3 covered by a reflector 7. This heater is arranged on rails so that it can be moved over the whole surface to be treated. Expansion joints may be ground in the intermediate material layer and filled with heat resistant material such as asbestos rope or with organic material which burns off during firing to leave empty channels. The intermediate layers may be applied using a vibrating trowel which temporarily reduces the viscosity. The second intermediate layer may be omitted; alternatively this layer may form the outer layer if a sintered surface is desired Other ceramic-forming mixtures for the intermediate and outer layers are given and glass spheres or other ornamental materials may be embedded in the outer layer prior to heating thereof. The heating oven may be heated by gas or electricity and waste heat from the oven may be used to preheat the next portion of the surface to which the oven is to be moved. High frequency heating may also be used in which case a wire mesh is embedded in the intermediate layer. If the surface of the intermediate layer is very rough, a thin layer of smoother material is applied prior to the application of the outer layer.

Aug. 2, 1938, Nos- 22852/38 and 7096/39. [Classes 2 (iii) and 15 (ii)] [Also in Group VIII] New quaternary ammonium salts are made by causing an aliphatic or heterocyclic tertiary amine to react with a halogenomethyl compound obtained by interaction of a carbamate of the formula R-O-CONH 2, where R is an aliphatic radicle of at least 7 carbon atoms, with formaldehyde (or a polymer thereof) and a hydrogen halide or phosgene, or with a dihalogenodimethyl ether. The products are stated to be different from the products obtained from carbamates of the same formula by the process of Specification 498,287. Suitable carbamates are octyl, decyl, myristyl, cetyl, octadecyl, octadecenyl and ceryl carbamates, also carbamates derived from the mixed alcohols obtainable by hydrolysis of the sulphuric esters made by sulphonation of polymerized lower olefines, and carbamates derived from alcohols which are also esters, e.g. #-hydroxyethyl stearate. The tertiary amines specified are trimethylamine, triethylamine, N:N<1>-tetramethylethylenediamine, dimethylcyclohexylamine, diethylcyclohexylamine, N-methylpiperidine, pyridine and #-picoline. In examples: (1) octadecyl carbamate is treated with paraformaldehyde and hydrogen chloride and the product is condensed with (a) pyridine, (b) triethylamine, (c) dimethylcyclohexylamine and (2) dodecyl-carbamate is treated with paraformaldehyde and hydrogen chloride and the product condensed with pyridine. The products are used for softening or rendering water-repellent textile materials of animal or vegetable origin, or composed of regenerated cellulose or of cellulose esters or ethers, by impregnating the materials with a solution or suspension of one or more of the quaternary salts in water or an organic liquid, and subsequently submitting the impregnated material to a short heat treatment to decompose the quaternary salt. Examples are given of the treatment of calico, viscose rayon, cellulose acetate fabric, and wool delaine. With natural or regenerated cellulose materials the process may be combined with a crease-resisting treatment, by treating the material with a solution or suspension of one of the quatenary salts, before, simultaneously with, or after a treatment with a medium comprising a partly condensed resinous condensation product derived from an aldehyde and urea or thiourea or derivatives thereof, or a phenol or an amino 1:3:5-triazine, or with the components of such resinous condensation product. Examples are given of the application of this treatment to viscose and mercerized cotton fabric.
