IPC: H01H71/62
Filed: 1976-02-23
Abstract: 1494461 Locking switches BROWN BOVERIE & CIE AG 23 Feb 1976 [21 Feb 1975] 7047/76 Heading H1N An arrangement for testing a circuit breaker and preventing unwanted reclosure of its main contacts comprises a key 2 which can be depressed against a spring 21 to a first position, when it causes tripping of (and thus tests) the circuit breaker, and subsequently can be turned by means of a tool, such as a screwdriver, to a second position wherein an arm 5 on the key holds it and displaces a lever 9 associated with the circuit breaker switching mechanism 10 to prevent operation of that mechanism to reclose the main contacts. The key 2 is guided for movement by a guide member 1 made of insulating synthetic resin, the arm 5 being guided in an L-shaped slot in this guide member. A resilient strip 11 running in a groove in flanges in the key slides out of that groove when the key is turned to the second position and holds the key in its turned position by friction.

Title: Improved devices for cleaning conveyor belts and the like
IPC: B65G45/18
Filed: 1930-03-04
Abstract: 349,649. Cleaning conveyer belts and like surfaces. SPENCER (MELKSHAM), Ltd., Melksham, Wiltshire, and PHILIP, W. L., Westwood, Lansdown, Bath, Somerset. March 4, 1930, No. 7113. [Class 19.] Conveyer belts or like surfaces are cleaned by brushing apparatus in the form of endless bands carrying sets of bristles and moving relatively to the belt or like surface. The removal of any substances tending to clog the brush is assisted by the opening out of the bristles as the endless band passes around its supporting rollers, and by the provision of metal plates or flickers against which the bristles engage. As shown, applied to a conveyer belt g, an endless band a carrying bunches of bristles b moves, transversely to the belt, over rollers c, d. The roller c is driven by chain-and-sprocket and bevel gearing or other transmission mechanism from the conveyer. Metal plates h engage the bristles preferably at some such position as is indicated in the drawing, at which the bristles are spread apart by passage over the roller c. The lower part of the brush may pass through a receptacle containing cleansing liquid. A metal shoot or other collecting means may be provided for the waste material.

Title: Improvements relating to regulating apparatus
IPC: G05F3/04
Filed: 1947-03-14
Abstract: 631,611. Automatic regulation. GLYNNE, A. March 14, 1947, No. 7117. [Class 38 (iv)] Regulating apparatus comprises two fourarm bridge circuits, each having in at least one arm of a pair of opposite arms devices 9, 10, e.g. metal filament lamps whose resistance varies with voltage, and in the remaining arms resistors not appreciably changing with temperature, the bridges being transformer coupled to an A.C. supply voltage as shown through inductive and capacitive impedances 20, 19 and 25 respectively so that the third harmonic frequency in the series output of the bridges is eliminated. The output voltage E of each bridge takes the form E=K1(V0-V) sin wt+K2 (cos 3 wt-cos wt) where V sin wt is the actual supply voltage, and V0 sin wt the datum value at which the voltage is to be stabilized, a D.C. voltage with that R.M.S. value being used for initially balancing the bridges. K1 is a constant and K2, being proportional to the supply voltage, approximately constant. By using impedances 20, 19 and 25 with values respectively advancing and retarding the bridge input voltages by 30 degrees the series output of the bridges takes the form with the third harmonic eliminated, which phase variable output may be amplified and used to control the output of a grid controlled mercury arc rectifier. Further, the cos w.t term may be eliminated by an output circuit series resistance 34 with phase quadrature voltage across it developed from a third transformer winding and choke 33, to give an output which may be amplified and added to the supply voltage to correct it. Alternatively, the resistance may be increased to overcorrect the quadrature term and the thus phase advanced output applied to the grids of a mercury arc rectifier as described in Specification 457,814. Specification 559,105 also is referred to.

Inventor: BAGLEY DONALD
IPC: C10B5/10
Filed: 1917-05-18
Abstract: 111,801. Bagley, D. May 18, 1917. Coke-ovens.-A regenerative oven with vertical heating flues has regenerators above and below each coking chamber extending along the length thereof, which operate alternately to heat the air supplied for combustion in the heating flues according to the direction of combustion therein, whether upwards or downwards. Gas is supplied to the heating flues v either from below or from above through conduits m, being delivered through removable nozzles. Air is admitted to the lower regenerator s' through a conduit n with openings into the regenerator which increase in diameter from the admission end of conduit, and is supplied to the heating flues near the bottom thereof through channels in the walls having outlet ports at two levels. Similar air-supply conduits and channels are provided for the upper regenerator s for use when downward combustion is being effected. Suitable reversing valves are provided. With upward combustion, the waste gases pass into the upper regenerators, either through the channels which supply air for downward combustion, or directly from the tops of the heating flues, in the latter case entering the upper regenerators at the top and passing downwards therein. The air may pass to the upper regenerators through passages in the arches of the coking chambers.

Title: Novel halogenated polyhydroxyl compounds and process for their production
IPC: C08G63/682
Filed: 1964-02-20
Abstract: The invention comprises halogenated polyhydroxyl compounds of the general formula: Ar[-O-R(OH)n- 1]m wherein Ar is a polyvalent radical of valency m and is derived from a perhalo-polyphenyl and/or a perhalopolyphenyl benzene, R is a polyhydrocarbon radical of valency n having 2 to 10 carbon atoms, and n and m are two whole numbers such that when n is equal to 2, m is greater than 1, with the exception of when n and m are equal to 2 and Ar represents a perchlorodiphenylene radical; and when n is greater than 2, m is equal to or greater than 1.  The compounds may be made by reacting a perhalopolyphenyl and/or a perhalogenated polyphenyl benzene with a polyol of the formula R(OH)n, in the presence of a hydrogen halide acceptor such as an alkaline inorganic compound or an organic base in a solvent for the product.  As perhalopolyphenyls are used compounds of the formula <FORM:1012328/C2/1> with X=0, 1, 2 or 3, and perhalopolyphenyl benzenes are used perhalo-1,3-diphenyl benzene, 1,3,5- and 1,2,3-triphenyl benzenes, and 1,2,4,5-tetraphenyl benzenes.  The preferred halogen is chlorine but fluorine, bromine or iodine may be used. Decachlorodiphenyl obtained as described in Specification 897,149 is specified.  Examples of suitable polyols are given.  In an example, bis-(2,2-dimethylolbutoxy-1) octachlorodiphenyl is made from decachloro-diphenyl and trimethylol propane in the presence of soda in dioxane.

Title: Improvements in and relating to pharmaceutical preparations for external application
IPC: A61K9/06
Filed: 1934-03-07
Abstract: Non-freezing oily substances suitable for the treatment of rheumatism by rubbing on the skin are obtained by heating an anhydrous salt of salicylic acid with esters of chloroacetic acid comprising esters of which the ester group consists of one or more open chain alcoholic residues having not less than three or more than eight carbon atoms, the products being salicoyl glycollic esters.  Isopropyl, butyl, amyl, hexyl and octyl esters are mentioned as being obtainable in this way.  By mixing these compounds with the known methyl and ethyl esters the tendency of the latter to crystallize is inhibited.  The mixture may be obtained by mixing the finished compounds or by conducting the above reaction with a mixture of the corresponding methyl and ethyl and the higher esters of chloroacetic acid.  A mixture of ethyl and isopropyl esters in equal parts is very suitable.  An example describes the preparation of salicoyl glycollic isopropyl ester.ALSO:Non-freezing oily substances suitable for the treatment of rheumatism by rubbing on the skin are obtained by heating an anhydrous salt of salicylic acid with esters of chloroacetic acid comprising esters of which the ester group consists of one or more open chain alcoholic residues having not less than three or more than eight carbon atoms, the products being salicoyl glycollic esters.
