Title: Process for the production of chlorobromomethanes
IPC: C07C17/10
Filed: 1960-03-31
Abstract: Chlorobromomethanes are prepared by subjecting a chlorinated methane to the simultaneous action of chlorine and bromine used in a molecular ratio of about 1 to about 1.3.  The reaction may be effected in the gaseous phase at 200-450 DEG C., or in an inert liquid at ambient temperature under the influence of actinic rays. Thus CH2ClBr may be prepared by reacting CH3Cl with chlorine and bromine in about equimolecular amounts, the molecular ratio of bromine to methyl chloride being between 0.01 and 0.35; or CHClBr2 and CClBr3 by using a bromine to methyl chloride molecular ratio of between 1 and 1.5.  Undesired reaction products may be recycled. Other products obtained in examples are CH2Cl2, CHCl2Br and CH2Br2. Specification 759,969 is referred to.

Filed: 1926-05-03
Abstract: 275,323. Mitchell, F. G., and Presland, C. W. May 3, 1926. Rotary tipplers.-A side-tipping tippler is loaded so as to turn under the action of gravity when restraining means is released, the apparatus being restored to its normal position by power against the action of gravity after the wagon has been discharged. As shown the tippler 1 is loaded by a weight 3, and is held and restored by a rope 5 and winch 6, 7. The movements of the tippler are limited by stops 8<a>, 8b engaging the supporting rollers 2. A lateral support 9 for the wagon is carried by arms 10 pivoted on the tippler at 10a and normally held clear of the wagon by ropes 12 wound on a hand-winch 14. When the wagon has entered the tippler the ropes 12 are payed out and the support 9 moves against the wagon by gravity, spring or equivalent means. On rotation of the tippler, holding bars 11 to which the ropes 12 are connected become locked automatically against toothed blocks 16 on the tippler. For holding the wagon against the rails, levers 18 pivoted on the tippler at 18<a> carry a sustaining bar 17 or they may be shortened to bear directly on the side wall of the wagon. The levers 18 are normally held in the raised position by bars 19 which rest at their lower ends in brackets 21. During the first movement of the tippler, the rods 19 turn about the edges 21a of the brackets and the levers 18 descend till arrested by the wagon. Catches 22 on the end rings of the tippler then engage teeth 19a and lock the rods 19 and the levers 18 or sustaining beam 17. When the tippler is righted, the bars 19 engage the brackets 21 and lift the levers 18.

Title: Improvements in or relating to the coating of thermoplastic plastics materials
IPC: B29C70/00
Filed: 1965-03-19
Abstract: An article formed from thermoplastic plastics material and reinforced with glass fibres and synthetic resin is produced by applying glass fibres to a heat-softened surface of an article of thermoplastic plastics material so that the glass fibres adjacent the surface of the article become embedded therein, cooling the glass fibre coated article, applying hardenable synthetic resin to the glass fibres of the coated article and curing the synthetic resin.  The article may be a web, plate or a moulded component.  The thermoplastics material may be polyvinyl chloride.  The surface of an already formed article may be preheated before the application of the glass fibres, or they may be applied whilst the surface is still soft as a result of the forming operation.  A web like article may be formed by extrusion and combined immediately with a glass fibres mat or fleece, e.g. by introducing the article after it has left the extruder between two moving glass fibre mats or fleeces.  Pressure may be used to assist the anchoring of the glass fibres, e.g. by passing the combined web and glass fibre mat or fleece through one or more adjustable pressure rollers.  Alternatively a layer of glass fibres may be introduced between two articles which are simultaneously united to the glass fibre layer and then separated such that separation occurs in the glass fibre layer.  The sandwich structure may be formed continuously.  The hardenable synthetic resin may be a polyester or epoxide resin and may be applied immediately after the formation of the glass fibre coated article or subsequently.  Additional glass fibres may be applied with the hardenable synthetic resin.  The products may be used for constructional or building purposes.

Title: Protection and indicating apparatus
IPC: H02H3/04
Filed: 1924-05-17
Abstract: 216,161. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Fran- þaise pour l'Exploitation des ProcÚdÚs Thomson-Houston). May 17, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Cut-out arrangements, particularly applicable to automatic substations, for selectively disconnecting a faulty feeder comprise high speed circuit-breakers in the generator circuits which open, together with the circuit-breakers in the faulty feeders which are differentially actuated, and are reset after an interval leaving the faulty feeders isolated and giving an indication as to which are faulty. In the arrangement shown in which two generators 7 supply substation busbars 1 through high-speed circuit-breakers 16, the bus-bars serving to supply a straight' feeder 3 and a feeder 4 branched into two 5, 6, a fault on one of the feeders causes the operation of a relay 20. This relay has two differentially-wound coils 20<b> and 20<a> which are connected between the bus-bar and earth, and across a series resistance 21 respectively. When abnormal current flows in the system, the current from the series resistance causes the operation of relay 20 which closes contacts 20<d> completing the circuit of the winding of a second relay 22 which opens contacts 22a and closes 22b. The contacts 22<a> are in the circuit of a no-volt coil 23 of the feeder circuit-breaker 9 and consequently this circuit-breaker assumes the off position. At the same time the overload on the generators brings out the high speed circuitbreakers 16 inserting resistances 19a into the supply circuit. If the overload is very heavy, the resistances 19<a> are rapidly heated up and operate thermal relays 19<b> thereby completing, through the back contacts of the high-speed circuitbreaker, a short-circuit for the no-volt coil of the switch 12 and completely breaking the generator circuit. The closure of the contacts 22<b>, however, completes the circuit of the winding of a time-delay resetting relay 24 which closes its contacts 24<a> thereby supplying the resetting coils of the high-speed circuit-breakers with current from the auxiliary power bus-bars 30. The open or closed condition of the circuit-breakers is indicated by the circuits 15 and by a current meter 26 and a lamp 29. The meter is connected across a resistance 27 located in a, circuit between the bus-bar and the far side of circuit-breaker 9, and the lamp is supplied from the auxiliary bus-bars when its circuit is closed by a relay 25 connected across the resistance 27. Similar indicating arrangements are provided in each of the two branches 5, 6 and, when the circuit-breaker 14 assumes the off position, both meters and signal lamps supply an equal indication but when one of the branch circuit-breakers is opened, the lamp &c. in association with the faulty feeder only gives an indication and its circuit-breaker 10 or 11 is then brought to the off position by hand. Hand control for the electromagnetic reclosure and opening of the high-speed circuit-breaker is provided for by the push switches 17, 18 respectively.

Abstract: 698,831. Modifying surface reflection. SCHROEDER, H. May 28, 1951 [Oct. 1, 1948], No. 12471/51. Class 97 (i). A method of reducing the surface reflection from an article of glass or silicates, comprises subjecting the article to an aqueous bath of an electrolyte having a dissociation constant at 20‹ C. greater than 10<SP>-6</SP>, said bath having a pH value within the range of 5 to 10 and containing, preferably in colloidal dispersion, polyvalent metals or hydrous oxides of these metals or compounds having complex anions, and continuing the treatment until the surface reflection has been appreciably reduced. If desired, the article after removal from this bath may be immersed in a second bath having a pH value lower or greater than the first bath and being at a temperature greater than or equal to room temperature. The first bath may contain aluminium, nickel or cobalt or hydrous oxides of these metals or compounds having complex anions, such as ferricyanide, ferrocyanide, aluminium fluoride, cobalticyanide, cobalt nitrate and niobium oxide. In one example, the article is immersed in a first bath containing sodium acetate, aluminium chloride and hydrochloric acid and then immersed in a bath containing not more than 0.5 per cent of hydrofluoric acid together with sodium carbonate, if desired. The sodium acetate in the first bath may be replaced by sodium arsenate and instead of aluminium chloride, aluminium sulphate or potash-alum may be used. Sodium tartrate may also be added to the first bath.
