Title: Tong caliper gauge
Inventor: YEOMANS KENNETH ALFRED
IPC: G01B7/00
Filed: 1965-06-14
Abstract: 1,109,238. Linear dimension gauge, electrical. BRITISH IRON & STEEL RESEARCH ASSOCIATION. July 26, 1966 [June 14, 1965], No.24969/65. Heading G1N. A linear dimension caliper gauge, e. g. for measuring hot steel billets of constant crosssection, has two arms 1, 2 Fig. 1 with a pair of strain gauges 10, 11 on each arm. One arm has two object engaging convex surfaces, Fig. 4, while the other arm has one, to ensure alignment of the gauge in a plane including the dimension to be measured. An adjustable stop 13, Fig. 3, may be provided to precisely locate the billet longitudinally of the arms. The spacing between the arms is adjustable by screws 7. The strain gauges are connected in a bridge circuit (not shown) having a centre zero meter, and it is arranged that the arms are parallel when a billet of the required dimension is inserted, the meter then indicating a null value. Any deviation from the desired dimension will then cause a deflection of the meter. When measuring the diagonal dimension of the billet the gauge is moved through a small angle around the billet and the true reading is the maximum value indicated which occurs when the arms are correctly aligned at the ends of the diagonal, as illustrated in Figs. 5, 6 (not shown). When measuring the dimension across the flats the gauge is similarly swept through an angle, but in this case it is the minimum value indicated which corresponds with correct alignment of the arms. To detect the maximum value the amplified bridge output is applied through a rectifier (16) Fig.7 (not shown) to a condenser 17, which is thus charged up to the peak voltage which is indicated on the meter. A switch is provided to discharge the condenser between readings. To reduce heat transfer the workpiece engaging surfaces are on hollow cylinders only the tips of which contact the arms, Fig.3. Each strain gauge may be on a steel strip which bridges a reduced portion of an arm, Figs. 8, 9 (not shown).

Patent GB-767416-A (GB)
Title: Process for oxidizing glutaraldehyde
IPC: C07C51/235
Filed: 1954-09-01
Abstract: Glutaric acid is prepared by oxidizing glutaraldehyde in an aqueous solution containing between 10 and 50 parts by weight of glutaraldehyde per 100 parts of water and glutaraldehyde.  The oxidation may be effected with molecular oxygen in the presence of an aliphatic monobasic aldehyde of lower molecular weight than glutaraldehyde, e.g. acetaldehyde or propionaldehyde.  Oxidation with molecular oxygen may also be effected in the presence of a metal salt as catalyst, e.g. a water-soluble salt of copper, cobalt, manganese, vanadium or mixtures thereof.  The preferred salts are acetate tetra-hydrates.  The amount of catalyst may vary from 0.001 to 5 parts per 100 parts by weight of glutaraldehyde and water.  The oxidation may also be effected with hydrogen peroxide, nitric acid, peracetic acid or perpropionic acid.  The oxidation proceeds best at 10 DEG  to 110 DEG  C. with any of the oxidizing agents.  The crude glutaric acid may be freed from water, heated to between 50 DEG  and 250 DEG  C. with at least one equivalent of acetic, propionic or butyric anhydride and the resulting glutaric anhydride hydrolysed using at least 1 mol. of water per mol. of anhydride to form a purified glutaric acid.  The hydrolysis preferably takes place at 50 DEG  to 150 DEG  C., desirably above the melting-point of the acid (97 DEG  C.).  Excess water may be removed by evaporation, by use of a drying agent or by azeotropic distillation with benzene or toluene. 4-Formyl butyric acid is produced as a by-product of the oxidation. In examples: (1) to (3) glutaraldehyde in aqueous solution is oxidized with air or oxygen in the presence of cobalt acetate tetrahydrate and zinc chloride giving glutaric acid with 4-formyl butyric acid as by-product; the product may be esterified with ethanol or butanol giving diethyl glutarate and ethyl-5,5-diethoxybutyrate or dibutyl glutarate and butyl-5,5-dibutoxy butyrate, respectively; (4) glutaraldehyde in aqueous solution is oxidized with hydrogen peroxide; (5) an aqueous solution of glutaraldehyde containing cobalt acetate tetrahydrate is oxidized with peracetic acid in acetic acid and the product is distilled with acetic anhydride to give glutaric anhydride; (6) and (8) molecular oxygen is passed through a mixture of acetaldehyde and cobalt acetate tetrahydrate and aqueous glutaraldehyde is added dropwise, the product is dehydrated by distillation with acetic acid and then further distilled in the presence of acetic anhydride giving glutaric anhydride; (7) impure glutaric acid is distilled with acetic anhydride to give glutaric anhydride; (9) glutaric anhydride is hydrolysed to glutaric acid by heating with water.

Filed: 1963-06-26
Abstract: 1,033,174. Valves. PUMPS & SOFTENERS Ltd. June 26, 1964 [June 26, 1963], No. 25479/63. Heading F2V. A valve arrangement for obviating waterhammer comprises means for preventing operation of a main valve until its communication with the supply line has been interrupted by an auxiliary valve. As shown, operation by means of lever 6 of a main rotary disc valve 1 comprising a ported movable plate 10 and a fixed ported rubber plate 13 is prevented until a member 23 is withdrawn, by means of ring 22, from a slot 4, thereby allowing the lever to be swung out of a notch 5A and rotated in the slot until it engages a further notch 5B or 5C. Withdrawal of member 23 causes operation of a spool valve 18 to admit fluid from a supply line 14 to a cylinder above an auxiliary valve 30 to thereby close the latter. When the lever has been moved, release of member 23 vents the cylinder to open the auxiliary valve. The movable plate 10 is connected to lever 6 by a spindle 8, and is formed with a central port and a ring of ports, two of the latter being permanently interconnected by a hollow dome 11 integral with the plate. Plate 10 rotates in a hollow housing 1B having an end wall 9, and plate 11 is secured between housing 1B and a housing 1C divided internally into chambers corresponding to the ports in plate 10, each chamber communicating with one of the pipes 14-17 and 50. Plate 11 has ports corresponding to the chambers and the ports in plate 10. In operation, as applied to controlling a water softener, filtering tank or ion-exchanger, when lever 6 is in notch 5A liquid flows from inlet pipe 14 through the central chamber and valve ports to the interior of housing 1B and thence to the chamber communicating with pipe 15. The liquid then returns via pipe 16 and is directed by the interconnected ports to the chamber communicating with pipe 50. In position 5B the flow path is modified to direct the liquid from pipe 16 to a drain pipe 17. In position 5C, the liquid flows from inlet pipe 14 to pipe 16 and returns via pipe 15 to be directed to the drain 17.

[Class 69 (ii)] [See also Group XXVI] A rotary engine or pump of the type shown is provided with a rotor 4 having a fixed axis coinciding with a shaft 2, and a stator 17 which is slidable vertically, to vary the eccentricity of the rotor to the stator. Fig. 2 shows the invention applied to a machine comprising a two cylinder pump contained by a slidable stator 17, which supplies a two cylinder engine 38 on a second shaft 30. The engine stator is fixed. A double - headed valve controls the flow of liquid from the pump to the engine according to the direction of rotation in which the engine is to be driven. In the pump, the stator has a web 11 with axial extensions 9 upon which the inner races 8 of bearings 7, which support the vanes 5, are held. The stator is moved manually by means of a thread 16, or it may be actuated automatically under pressure control or by a governor. The casing 1 is filled with liquid such as a light oil. The vanes may be pressed outwards by liquid under pressure, and channels 12 are provided for leakage. The tips of the vanes preferably form arcs of the same circle, and the vanes may be divided, the two parts being pressed apart by springs. The vanes are spaced angularly to one another in the two rotors, both in the pump and engine. The engine may be duplicated on two shafts which may be the driving axles of a motor car, so that a differential gear effect may be obtained. In a modified arrangement, the pump and engine shafts are not in alignment, but parallel within a casing filled with liquid. The eccentricity of the pump rotor may be altered to secure reverse drive of the motor shaft. The motor may be the variable unit, and the pump of fixed capacity, or variable.

Abstract: 466,247. Coke ovens. PAVITT, W. H. Sept. 19, 1936, No. 25539. Convention date, Sept. 28, 1935. [Classes 51 (i) and 51 (ii)] In an underfired regenerative coke oven the air supply for the regenerators can be drawn in part from the basement space beneath the oven structure and in part from some other source, so that by varying the amounts from the two sources overcooling of the basement can be avoided. In one construction, Figs. 1-3 (not shown), the reversing-valves at the two sides of the battery are arranged in enclosed alleyways in communcation with the basement space. Doors control the admission of air to the alleyways and the basement space, and allow variation of the amount of air drawn through the latter. In the construction shown in Figs. 4, and 5 each reversing-valve has two damper-controlled air inlets O, OA leading respectively to the basement space and the side alleyway. The valve has two chambers IA and IB separated by a partition consisting of a full depth vertical wall I', and two half depth walls, I<8>, I<9> respectively above and below. an horizontal partition I<6>, so that the two chambers communicate respectively with upper and lower regenerator sole flues, as described in Specification 465,378. In another form, Fig. 7, air from the alleyways is admitted to the basement space through pipes OE having their damper-controlled lower ends O<13> arranged in proximity to the air inlets OD to the reversing-valves. The upper ends of the pipes OE are hooded to prevent entry of dust, and the inlets to the conduits OD are controlled by placing a variable number of strips or finger bars R across the recessed rectangular seatings O<12> at the inlets. In a further form, Fig. 10 (not shown), the pipe OE is connected to the conduit OD, and two valves are fitted one for controlling the pipe OE, and the other the admission of air to the conduit OD from the basement.
