Abstract: 444,398. Press - button retractive switches for vehicles. LUCAS, Ltd., J., and LUCAS, O., Great King Street, Birming- ham. Sept. 19, 1934, No. 26911. [Class 38 (v)] A push-button switch, specially useful for flashing the lamps of a car intermittently when the horn may not be used, is provided with means enabling the circuit to the lamp to be normally " on " or normally " off " at will. In the form shown in Fig. 1, the push button contact g is adapted to co-operate either with a contact c or with a contact b, the particular contact c or b being selected by operation of a lever e which slides the contacts b, c sideways. In the position shown the circuit to a lamp a is normally open and depression of the push i would close it. If the lever e were operated the contact b would engage the contact g so that the circuit would normally be closed, but depression of the push i would in this case open it. In the form shown in Fig. 3, a snap action switch q, n connects the source of current to one of two springs s, t, the free ends of which are separated by an insulating piece u. The springs s, t lie between the ends of a U-shaped contact w connected to the lamps, so that if the spring s is rendered live by the switch q, n the circuit to the lamps will be normally closed, but if the spring t is live the circuit will be normally open. Depression of the push button 2 moves spring s out of engagement with the contact w and spring t into engagement with it so that the circuit to the lamps will be opened if previously closed and vice versa.

Title: Solid, Fusible Photographic Processing Compositions and use thereof
IPC: G03C8/40
Filed: 1966-06-20
Abstract: 1,155,948. Heat-processing of photographic silver halide materials. EASTMAN KODAK CO. June 20, 1966 [June 18, 1965], No.27545/66. Headings G2A and G2C. A non-light-sensitive silver halide processing composition contains (a) a solid organic substance or a mixture of such substances which is miscible with H 2 O when molten, (b) 2% to 30% by weight of water, and (c) a photographic silver halide processing agent, the composition having a m. p. below 115‹C. The composition may be a layer on a separate or the same support as the silver halide layer, or the composition may be in the form of a block. The processing agent may be a developer, fixer, stabilizer, toner, stop-agent, alkali or a mono-bath comprising developer and silver halide solvent. The solid organic substance may be a polyalkylene glycol; hydroxyethyl cellulose; carboxy methyl cellulose; a wax; or a compound of the formula XCONRR<SP>1</SP>, YSO 2  NH 2  or RCH-CH 2 -O-C=O, wherein X is H, alkyl of 1-4 C atoms, R<SP>1</SP>NH-, R<SP>11</SP>O-, or -(CH 2 ) n CONRR<SP>1</SP> (where n is 1-4); R<SP>1</SP> is H or CH 3 ; R<SP>11</SP> is alkyl of 1-4 C atoms; X and R<SP>1</SP> together may form -(CH 2 ) a  CO- or -(CH 2 ) b  - where a is 2-3 and b is 3-5; R and R<SP>1</SP> together may form a heterocyclic ring; and Y is alkyl of 1-4 C atoms, NH 2 -, R<SP>11</SP>O-, or aryl or substituted aryl. Flexible film-forming binders may also be included when the composition is in the form of a layer. When the layer is coated on to a silver halide layer, a barrier layer may be coated therebetween, and when the silver halide layer has been exposed it may be processed simply by heating the material. The silver halide layer and the processing composition layer may be on opposite sides of the support so that a stack of exposed sheets may be processed together, the processing layer on one sheet processing the silver halide layer on the next sheet. When the composition is on a separate support from the silver halide layer or is in the form of a block, the exposed silver halide material may be brought into contact with the composition which is melted before or during the contact. Heating may be effected by rubbing or by contacting with a heated plate. Examples describe developer, mono-bath and stabilizer compositions in the form of layers and blocks and a silver-salt diffusion receptor sheet containing Carey Lea silver and a developer layer. A processing machine (see Fig.) contains blocks of meltable developer and stabilizer compositions 1, 2 and 3, an exposed silver halide material 4 being processed by passing between the heater and the blocks so that melted processing composition is spread on the silver halide layer, excess composition being removed by scrapers 7.

Abstract: 226,509. British Thomson-Houston Co., Ltd., (Assignees of Zabel, W. P.). Dec. 18, 1923, [Convention date]. Addition to 201,900. Vacuum tubes.-In a process of preparing an electrode having high electron emissivity as described in the parent Specification, the reducing agent consists of a carbonaceous material in a liquid, for instance a colloidal solution of graphite such as that known by the registered Trade Mark " Aquadag." The base material, preferably non-sag tungsten reduced from oxides derived from combinations of tungstic oxide with fixed alkalis, is mixed with Aquadag and thoria in the form of thorium nitrate, in proportions sufficient to produce 0.5 per cent of carbon and 2 per cent of thoria by weight in the powder. Distilled water may be added. The mixture is dried over a steam bath and stirred frequently to prevent segregation of graphite and thoria, and is then pulverized and passed in metal boats through a continuous reduction furnace at a temperature of 800‹-900‹ C. in the presence of hydrogen. The reduced metal is passed through a sieve, mixed, pressed into slugs, and sintered by passing at the rate of one inch per minute through an electrically heated tube at a temperature of 1280‹ C; the slug is turned over and passed through again. The ingot is treated in dry hydrogen by passing current through it, the voltage and current being very gradually raised and then reduced. During the subsequent drawing process a current of gradually increasing strength is passed through the ingot or wire. Details of current strength are given. The wire may be used without cleaning, but is preferably cleaned to remove carbonaceous material or graphite. In some cases a coating of carbon may be added as described in Specification 184,446, or a coating of Aquadag or a carboncarrying medium may be applied so as to leave a deposit of carbon. In modified processes a starch solution may be used, or carbon may be introduced to the base material from a solution of thorium ammonium oxalate.
