Patent FI-964093-A (FI)
Inventor: MUECKSCH DIETMAR
IPC: H01H3/30
Filed: 1996-10-11
Abstract: The invention concerns a device for tensioning the cut-in spring in actuator units for circuit breakers, in particular vacuum circuit breaker, the cut-in spring (7) being designed as a tensioning spring which is in contact with a cam (2) mounted on the cut-in shaft (5) and which can be tensioned both by an electric motor (20) and by a hand-turned shaft (21) through a spur-gear train, the last spur gearwheel (1) also being mounted on the cut-in shaft (5). The aim of the invention is to design a tensioning device in which the spur-gear train operates without overrunning, and reversing of the cam (2) is prevented or limited by the cut-in spring (7). This is achieved by virtue of the fact that the last spur gearwheel (1) in the spur-gear train is disposed over an overrunning bearing (6) on the cut-in shaft (5) in such a way that, when cut-in spring tensioning begins, the cam (2) and hence also the cut-in shaft (5), are carried directly by the last spur gearwheel (1) out of a position in which they are located past the bottom dead centre position (9) of the shaft (5) as the cam (2) rotates upwards, while, during the cut-in phase, the last spur gearwheel (1) is locked in position, when the cut-in shaft (5) turns through bottom dead centre (9), by the overrunning bearing (6) and by the operative connection with the other spur gearwheels in the spur-gear train.

Patent GB-370937-A (GB)
Title: Improvements in or relating to the production of compositions of or containing rubber and articles therefrom
IPC: C08K5/47
Filed: 1931-01-13
Abstract: Sticky compositions of rubber or the like for softening rubber, for use in rubber cements, or for joining rubber to other articles are produced by adding to compositions of rubber or the like small amounts of a mercaptothiazole and heating the mixtures in the absence of a vulcanizing agent to temperatures of 50-100 DEG  C. until the desired degree of stickiness is obtained.  The mercaptothiazoles used are of the general formula- <FORM:0370937/V/1> when R1 and R2 are hydrogen atoms or any residues such as methyl or phenyl and X is a hydrogen atom or a metal such as potassium or zinc.  The two carbon atoms of the thiazol ring may also form part of any other ring, e.g. a benzene ring.  The degree of stickiness depends on the amount of accelerator used, the temperature, and time of heating.  The products may be vulcanized by the addition of e.g. sulphur.  Latex containing a mercaptothiazole may be applied to latex-proofed fabrics to render the surface tacky for powdering.

Title: Treatment of ceramic pouring tubes
Inventor: ZICKEFOOSE ELLIS JAMES
IPC: B22D41/54
Filed: 1959-01-13
Abstract: A mounted ceramic pouring tube, used for pressure casting, is prepared for the casting operation by heating uniformly from below the temperature at which the lowest discontinuity in the thermal expansion curve of the ceramic occurs to the temperature which exceeds the last discontinuity preceding the temperature of the material to be cast, and maintaining the temperature above the aforesaid discontinuity until the tube is used.  The temperature increase should be below 200 DEG F per hour, which may be achieved by either periodically raising the temperature in one pre-heating furnace, or by passing the pouring tube through a plurality of furnaces.  The preferred initial temperature for the treatment is not over 250 DEG F, the upper limit being preferably 1800 DEG F although steel casting may be effected at 2900 DEG -2950 DEG F.  The tube which for preference is composed of 51-53% SiO2 42-44% Al2O3 may be secured, prior to heating, in the housing using a wet alumino silicate, air-setting cement and may be glazed using for example a borate containing glaze.

Title: Improvements in or relating to the preparation of alkali metal and ammonium dihydroxy aluminium carbonates
Inventor: GROTE IRVINE WALTER
IPC: C01F7/782
Filed: 1955-01-18
Abstract: Dihydroxy aluminium alkali metal or ammonium carbonate of formula (HO)2AlOCO2X where X is an alkali metal or ammonium radical is prepared by reacting an aluminium compound as defined below with an alkali metal or ammonium bicarbonate in the presence of water to obtain a precipitate of the aluminium complex which is separated from the aqueous remainder of the mixture. Suitable aluminium compounds are water dispersable aluminium hydroxide or aluminium hydroxide gel, an aluminium acylate which is hydrolysable by water and water-soluble aluminium salts, the anions of which form a weaker bond with aluminium than does the -OH group, that is those anions which have a greater tendency to neutralize the alkali metal or ammonium cation than they have to remain bonded to the aluminium.  Organic aluminium salts which may be used are aluminium acetate, acetotartrate, benzoate, boroformate, borotartrate, glycinate, lactate, glycolate, alaninate, paraphenolsulphonate, and beta-naphtholsulphonate. Aluminium oxalate, salicylate and aluminium salts of C8-C18 fatty acids such as the oleate, stearate, palmitate and myristate may also be used in the presence of organic solvents or basic reactants which increase their solubility.  Inorganic aluminium salts include the borate, bromate, bromide, chloride, iodide, phosphate, sulphate, and nitrate.  The aluminium compound and the bicarbonate may be admixed dry and added to the water or they may be added separately or they may be dissolved separately and the solutions mixed; heat may be applied to expedite their reaction.  Normally, equimolecular proportions are employed, but excess bicarbonate may be used to ensure completion.  Detailed examples relate to the reaction of sodium carbonate and bicarbonate with aluminium acetate, sulphate and hydroxide, the latter being in the form of a dried gel or a compressed gel containing 85-90 per cent of water. Specification 756,482 which relates to the preparation of the same compound by reacting an aluminium alcoholate with a bicarbonate, is referred to.ALSO:Dihydroxy aluminium alkali metal or ammonium carbonate of formula (HO)2AlOCO2X, where X is an alkali metal or ammonium radical (see Group III) is employed as an antacid.  The compounds are the same as those described in Specification 756,482.

Title: Improvements in or relating to respirators for artificial ventilation
Inventor: BEAUMONT GEORGES
IPC: A61M16/00
Filed: 1971-01-13
Abstract: 1281802 Artificial respiration apparatus G BEAUMONT 13 Jan 1971 [16 Jan 1970] 1599/ 71 Heading A5T A respirator for artificial ventilation comprises a monostable amplifier 3 and a bistable amplifier 5 in a circuit connecting a source of pressurised fluid 1 and a mouthpiece 16. In operation jets entering the amplifiers 3 and 5 through inlets PS are directed through outlets O. Outlet O of amplifier 3 connects via valve 7 with inlet C3 but provides insufficient pressure to deflect the jet to outlet 1. When the patient aspirates through mouthpiece 16 the presure in a valve 14 is reduced and this is communicated with inlets C4 via a pipe 22. The reduced pressure switches amplifier 3 to outlet 1 which connects to inlet C3 of amplifier 5 thus switching amplifier 5 to outlet 1 which inflates bladder 13 closing expiration orifice 20 and operates a relay 11 allowing a flow of gas to the mouthpiece 16 on insufflation. Flow through a venturi 18 induces atmospheric air. When a predetermined presure is attained in the valve 14 this is communicated by pipe 22 to inlets C4 of the amplifiers to switch the flows through both amplifiers to outlets O hence closing relay 11 and deflating bladder 13 allowing normal expiration. For automatic operation a switch 9 is opened allowing a flow determined by valve 8 which after an expiration pause determined by the time taken to fill a constant volume vessel 10 is filled activates a control inlet C1 to switch the amplifier 5 to outlet 1 thus activating relay 11 and inflating the bladder 13 for insufflation. In the embodiment of Fig. 3 (not shown) amplifier 5 has a vent port (E1) instead of control inlet Cl. Automatic operation is effected by a pneumatic relay (34) Figs. 4 and 5 (not shown). During insufflation no pressure appears at outlet (O) of the amplifier (5) which communicates with chamber (43) of the relay (24) so that a membrane (42) is unseated from an orifice (41) allowing the jet from outlet (O) of amplifier (3) to escape to atmosphere through chamber (40) of relay (34). At the end of insufflation the pressure in duct (22) switches amplifier (5) to outlet (O) deflecting the membrane (42) onto orifice (41) thus diverting the flow from outlet (O) of amplifier (3), which is controlled by the valve (8) into the bladder (36) which when full closes duct (38) which connects to vent port (E1) of amplifier (5) and thus switches the flow. from outlet (O) to outlet (1) to begin another insufflation period. A humidifier (27) may be included in the circuit Fig. 3 (not shown) and the whole apparatus encased Fig. 2 (not shown).

Filed: 1960-01-18
Abstract: 936,136. Valves. A. LINS. Jan. 18, 1960 [Jan. 19, 1959; Jan. 7, 1960], No. 1738/60. Class 135. An electrically controlled thermally-actuated valve comprises a chamber 8 divided into two compartments by a flexible diaphragm 9, the upper compartment containing a volatile liquid and an electrical resistance heater 11. The lower compartment contains an incompressible liquid which communicates with a cylinder 4, housing a piston 5, through a perforated plate 7. A valve spindle 15 is urged towards the piston 5 by a spring 17 and a lever 20 pivoted at 21 may be provided between the spindle and piston to lock the spindle in an appropriate position by notches 25 in a groove 24 of the housing 23. In operation a current is supplied to the heater 11 causing the volatile liquid to vaporize and create a pressure which acts on the diaphragm 9 and through the incompressible liquid to move the piston 5 downwards against the spring loading 17. Such movement of the piston 5 and hence the spindle 15 continues until the amount of heat supplied by the resistance 11 is equal to the amount of heat dissipated by the walls of the chamber 8. To ensure efficient cooling of the walls of the chamber 8 by the surrounding air, openings 23a may be provided in the housing 23. In the embodiment described the movable valve member 27 attached to the spindle 15 controls the flow of water from a return pipe 29 of a hot water heating system to two outlet pipes 30, 31, the pipe 30 leading to the boiler while the pipe 31 leads to the outlet from the boiler. An adjustable temperature feeler is provided to regulate the current supplied to the resistance 11, thus controlling the temperature of the system. In a modification the resistance 11 is housed in a pocket of chamber 8 extending into the volatile liquid space so that the heater may be removed for repair or replacement without opening the space. The pocket is preferably arranged so as to be in contact with the liquid component of the volatile liquid at least in the major portion of the entire temperature range.
