Abstract: 858,118. Coating webs. ILFORD Ltd. July 5, 1957 [July 6, 1956], No. 21098/56. Class 140. Two or more liquid coatings are applied to a web support in superposition by applying said coatings simultaneously; each of said coatings or all such coatings subsequent to that which is to form the layer directly on the web support, being produced by feeding the coating liquid to the web via a liquid permeable porous block of small pore dimensions. The porous block may be of porous glass, plastic or metal. The method is applicable to coating material with gelatino silver halide emulsions and a " supercoat " which is thin and transparent, e.g. gelatin. As shown, a pool A supplies undercoat liquid to a web. B is a chamber containing a further coating liquid under pressure, C is a curved sheet of porous material, D is the channel in which the two coats are formed and flow without turbulence and E is the double-coated web. Further coats may be applied by dividing chamber B into two or more chambers, each fed with the desired coating liquid at a suitable pressure.

Title: Improvements relating to forming a supply of molten metal in welding or other operations
Inventor: ROHRBERG RODERICK GEORGE
IPC: B23K10/02
Filed: 1970-05-01
Abstract: 1293228 Welding by fusion; casting processes NORTH AMERICAN ROCKWELL CORP 1 May 1970 [8 May 1969] 21100/70 Headings B3F and B3R An electric arc torch (Fig. 1) in which a consumable electrode 11 is used to form molten metal for welding or casting, comprises one or more apertures 50 arranged to direct ionizable gas at an acute angle into the arc, and one or more further apertures for directing a curtain of shielding gas around the arc. The apertures 50, of which there may be eight, cause a cone of gas to be directed towards the electrode, the gas being, e.g. helium, supplied to a chamber 52 in the torch. A surrounding chamber 32 directs a flow of gas generally to the region of work. Welding.-The torch can be used to perform a weld between two workpieces. In seam welding (Figs. 2-6, not shown), the electrode tip is positioned between the two workpieces, which can be vertically misaligned. A backing bar and gas backing can be used. During welding overhead, it is stated that excessive drop-through is prevented by cooling of the lower part of the bead due to rapid motion of the arc zone. Welds other than seam welds can be performed. In one arrangement (Fig. 9, not shown) workpieces (150, 152) are joined by a localized weld which fills a preformed bore in one workpiece (150) and also penetrates the surface of the other workpiece (152) to some extent. The bore, and hence the weld, can have a surface widening. Workpieces (150, 152) can be metal, but the one workpiece (150) may be a non- metal. In another arrangement (Fig. 11, not shown), the weld fills a pair of bores preformed in the workpieces (150, 152) the bores initially having a horizontal misalignment. The superposed workpieces (150, 152) in these figures can be seam welded, the bores in this instance being horizontally elongate. Weld configurations obtained by varying different parametres during seam welding are described (Fig. 14, not shown). Casting.-The torch can be used to cast a flange on to the surface of a plate (174) (Fig. 12, not shown). Ceramic die-blocks (170, 172) confine the deposited metal. A flat upper surface of the cast flange is obtained by subsequent machining. The torch can also form part of a centrifugal casting apparatus.  In one form (Fig. 15) the torch is mounted on a rotor 190 and the arc struck between the electrode and a throat 211 of a mould 208 into which the metal is flung as the rotor rotates. A counterbalance 206 is provided. In another form (Fig. 16) the torch 221 is rotatable within a ring of moulds 228.

Filed: 1963-05-28
Abstract: 974,780. Press button retractive switches. CUTLER-HAMMER Inc. May 28, 1963 [May 28, 1962], No. 21373/63. Heading H2B. In an electric switch, means are provided for preselecting a switch contact combination which is to be actuated by an actuating member and lost motion exists between a rotatable selector and the moving contact carrier. The switch comprises a base 2 carrying four fixed leaf spring contacts 16, 18, 20, 22, a contact carrier 26 with two bridging contacts 32, 34, a trigger 8 and a selector 10 with a shaft passing through the trigger 8 and engaging the end wall of the carrier 26. The base 2 is separated from a metal switch frame 4 by an insulating plate 6. The shaft 10a of the selector has raised portions 10e which engages ridges on the carrier 26 to rotate the carrier through 90 degrees so that contact 32 bridges contacts 18, 20 rather than contacts 16, 18 and contact 34 bridges contacts 16, 22 rather than 20, 22 as shown in Fig. 5. Initially the selector 10 is in the position shown in Fig. 3 (not shown) and after rotating it 90 degrees the shaft 10a is in the position shown in Fig. 5, but after a further 90 degrees, the carrier 26 is rotated so that bridging contacts 32, 34 are moved to their second position. Ridges 8g on trigger 8 engage grooves 10b in the selector to locate the two positions in which the switch may be actuated by depressing the selector and trigger, a ridge on the selector moves within a groove 8d in the trigger and also a knob on the trigger moves in a slot in the carrier 26 to prevent further rotation of the selector or carrier. Springs 12, 14 which fit in recesses 8h in the trigger and engage the frame 4 retract the trigger and selector, while spring 24 provides snap action indexing, or may be omitted if springs 12 and 14 are strong enough. The trigger may be retained in its depressed position by a locating pin engaging a recess in the trigger, Fig. 2 (not shown). In another embodiment, the head of the selector fits into a recess in the trigger and forms only part of the end of the trigger, Fig. 11 (not shown). Specification 973,549 is referred to.

Patent GB-420544-A (GB)
Title: An improved method of producing hard metal alloys
IPC: C22C1/05
Filed: 1933-08-01
Abstract: In a method of producing hard alloys containing a carbide of a refractory metal such as tungsten, and a more fusible metal or alloy such as cobalt, the metal or alloy is added wholly, or at least to the extent of 35 per cent, in colloidal form to the carbide, and the mixture is pressed and sintered in known manner. The metal or alloy may be added in the form of a colloidal solution, for example, the hydro- or organo-sol, the solvent being evaporated after mixing with the carbide.  The mixture after further mixing is pressed, and sintered in vacuo once or twice. Alternatively, the metal may be separated from the colloidal solution and introduced as a dry powder to the carbide.  In the case of articles of a complicated shape the mixture is dried only to the consistency of dough and then pressed, rolled, or cast. The metal or alloy may also be introduced as a colloidal solution of its oxide or hydroxide, or a freshly precipitated, highly dispersed, semi-colloidal hydroxide or hydrated oxide, the mixture being subsequently reduced by hydrogen.

Title: Apparatus for converting the reading of a deflection-type measuring instrument into digital form
Inventor: MEDLOCK REGINALD STUART
IPC: H03M1/00
Filed: 1958-07-04
Abstract: 937,400. Interrupters. GEORGE KENT Ltd. Oct. 5, 1959 [July 4, 1958], No. 21589/58. Class 38 (5). [Also in Group XIX] Apparatus for converting the reading of a deflection-type measuring instrument into digital form comprises a cam 1 rotatable at constant speed and a follower 2 coupled to the instrument and movable over the face of the cam 1 to be actuated thereby for different time periods in each revolution thereof governed by the deflection of the instrument so as to actuate a switch 10 controlling the output of a generator transmitting signals to a counter at a much higher frequency than the cycles of operation of the cam. The position of the arm 5 about its pivot 6 is controlled by the instrument through linkage 14, having a zero-adjusting screw 15. The arm 3 of the follower 2 is pivoted to the arm 5 at 4 and has an extension 7 bearing on an arm 8 fast with a spindle 9 operating to open a normally closed switch 10. A spring 11 operates on the arm 8 urging the follower 2 against the face of the cam 1 which thus holds the switch closed until, in its rotation, the shaped cam periphery clears the follower. Each time the cam 1 completes a revolution a follower 13, Fig. 2, closes the switch 10 just before a cam 12 restores the follower 2 to face engagement with cam 1. The cam 1 may be shaped to modify the scale of readings, e.g. a non-linear input could give a linear output. Several generators each fed by a different instrument could all feed the same counter. Signals could be fed only when the measurement deflection is outside preset limits.

Title: Fuel oil composition
IPC: C10L1/232
Filed: 1957-07-08
Abstract: An additive to fuel oils with boiling points between 100-750 DEG  F. is formed by reacting a naphthenic acid having a molecular weight up to 300 with an alkylene polyamine represented by R1-NH(RNH)n H wherein R1 is hydrogen or an aliphatic group, preferably having 8 to 18 carbon atoms, R is an alkylene group having 2-3 carbon atoms and n is an integer equal to, or greater than one but preferably from 1 to 4, e.g. diethylene triamine or dipropylene triamine.  From 2 to 4 molecular proportions of naphthenic acid can be reacted with 1 molecular proportion of the polyamine when R1 is H or does not contain more than 7 carbon atoms.  If the R1 contains at least 8 carbon atoms then the reacting molecular proportions of acid to polyamine should be 1 as to 1.  Between 0.005 per cent and 0.05 per cent (by weight) of the soluble reaction product is added to the fuel oil which is a distillate fuel oil including domestic heating fuel oil, jet fuel oil and hydro-refined fuel oil.  The naphthenic acids are monocarboxylic acids obtained from crude petroleum with, preferably, an acid number of 200, an average molecular weight between 275 and 300 and with an average of 15-20 carbon atoms per molecule.  The alkylene polyamines may be diethylene triamine, triethylene tetramine, tetraethylene pentamine, pentaethylene hexamine, propylene diamine, dipropylene triamine, propyl diamine or mixtures thereof.  Specification 791,071 is referred to.

Title: Improvements relating to mixture compressing rotary piston internal combustion engine
IPC: F02B53/00
Filed: 1967-05-10
Abstract: 1,139,157. Rotary-piston internal combustion engines. DAIMLER-BENZ A.G. May 10, 1967 [May 11, 1966], No.21656/67. Heading F1F. In a mixture-compressing rotary-piston I.C. engine, particularly of trochoidal type, having a three (or more) sided piston 5, planetarily rotatable within a casing having a peripheral wall 1 through which opens an exhaust port 2 and an admission port 3 controlled by the piston corners, an overflow passage 14 fitted with a throttle valve 15 inter-connects the compression and suction chambers 12, 11 at points in the peripheral wall where there is a pressure drop towards the suction chamber 11 at the time when a piston corner is passing between the points. The throttle valve 15 which is located near the compression chamber is linked with the throttle flap 10 in the admission port 3 and is open during engine idling and partial load and closed at all other times. During engine idling with the throttle flap 10 closed, only exhaust gas is for the most part contained in the suction and compression chambers 11, 12 and only a small amount of fresh gas located is initially in the vicinity of the trailing piston corners of the two chambers. As the piston rotates fresh gas at the trailing piston corner of the compression chamber 12 is transferred through the passage 14 to the leading end of the suction chamber 11 so that when that chamber becomes the compression chamber fresh gas is available for reliable ignition in the neighbourhood of the spark-plug 13. At partial load, and particularly in the case of carburetter operation, the main portions of the chambers are filled with a weak mixture which is generally inadequate for ignition and without the passage 14 the over-rich mixture would not be readily available in the neighbourhood of the spark-plug. As before, the over-rich mixture is transferred through the passage 14 to the leading end of the suction chamber to be readily available for ignition when that chamber becomes the compression chamber. The linkage between the throttle valve 15 and throttle flap 10 is such that with increasing opening of the flap 10 the valve 15 is closed to avoid losses under full load operation.

Abstract: 666,978. Rolling. RENDLEMAN, N. Aug. 17, 1948 [Feb. 3, 1948], No. 21697/48. Class 83 (iv). A rod mill having a succession of roughing roll stands has means for separately driving the first two of said stands independently of all the others, means for driving all of the others together, said first two stands being adjustable as to speed and roll pass section to compensate for variations in the initial cross-sections of the billets, the respective pass areas of each of the succeeding stands of the train and relative speeds thereof being substantially fixed. The roughing train is followed by an intermediate train of a succession of pairs of stands 9-10, 11-12, 13-14, 15-16 with loops between successive pairs, and a finishing train of a succession of stands 17-22 driven through gearing by a motor M<7>. A shear may be interposed between the roughing train and the intermediate train. Figs. 6A and 6B, together show in diagrammatic form the roll stand combinations for the entire range of rod sizes up to <21>/32 inch. Figs. 8-9 and 10-11 (not shown), indicate the manner in which the stands are arranged for larger bar sizes in the ranges <11>/16-<7>/8 inch and <15>/16-1<1>/4 inch respectively. In a mill having three working lines A, B and C, Fig. 7, since the passes in the roughing train are never changed and 2 inch x 2 inch, 2“ inch x 2“ inch and 2¢ inch x 2¢ inch cross-section billets are all rolled through the same passes, the rolls of each stand are provided with a number of like passes. Thus, when new grooves are needed the rolls are shifted laterally to the working line, and since all passes on any line will wear at about the same rate, rolls do not have to be discarded until all the passes are worn down.
