Abstract: 1292172 Magnetrons ENGLISH ELECTRIC VALVE CO Ltd 19 April 1971 [1 July 1970] 31939/70 Heading H1D A tunable magnetron includes a plurality of tuning devices each of which has only two stable tuning states corresponding to two different frequencies, and control means for independently changing over the states of one or more of the devices; preferably the changes of frequency associated with different devices are different and in binary relationship, whereby a plurality of different frequencies which differ from one another by a constant frequency difference may be obtained by changing the states of a suitable combination of the devices. As shown, the tuning devices may be formed by a switch 9, 10 in each magnetron cavity (only one shown) which partially short circuits its cavity when closed by the flexure of the metal strip 11 from one of its equilibrium positions to the other by the action of a piezoelectric device 13. Alternatively (Fig. 7, not shown), a conductive member may be arranged to extend above each anode vane, and be displaceable sideways by a piezoelectric device. In a coaxial magnetron, the tuning devices may be provided at spaced positions in the common resonator. Reference is also made, without description, to tuning devices formed by dielectric members, or by switchable means for producing a gas or electron discharge for interaction with the magnetron r.f. field, and to the use, for producing the movement changing the state of the device, of electric, hydraulic, pneumatic, or mechanical means.

Abstract: 1,059,592. Tube expanders. CARRIER CORPORATION. Aug. 13, 1963 [Aug. 17, 1962], No. 31960/63. Heading B3J. A tube expander comprises rollers loosely retained in a housing, a mandrel, having a tapered end engaging said rollers, disposed within said housing and a spring arranged in said housing yieldably urging said mandrel inwardly of said housing, the arrangement being such that confinement of the rollers by the inner surface of a tube to be expanded causes axial movement of the mandrel, accompanied by generated radial forces expanding the tube upon rotation of said housing. In operation the end of the tool is inserted into the open end of a tube to be expanded. An abutment member 40 is adjusted in a housing 10 to move a mandrel 26 axially so that its tapered end 28 forces rollers 24, disposed in skew slots 22 in the housing 10, into engagement with the tube. The housing 10 is then rotated and the rollers 24 as a consequence of such rotation draw the mandrel forward against the action of a spring 38, the mandrel causing the rollers to move outwardly to expand the tube. When a thin part 32 of the mandrel reaches the rollers 24 the rollers drop inwardly and the rolling action is terminated.

Abstract: 678,310. Making insoles. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Dec. 13, 1950 [Dec. 14, 1949], No. 32059/49. Addition to 630,061. Classes 17 (i) and 17 (ii). The apparatus for making ribbed insoles by tucking canvas progressively lengthwise into a grooved matrix member which supports the canvas and which is fed relatively to a tucking tool, as described in the parent Specification, is modified in the following respects:- (1) The various instrumentalities, viz. tucking tool 310, and work feeding foot 420, arc coupled to plungers which are actuated by a barrel cam 352, Fig. 10, having a plurality of tracks and mounted on a main shaft 100 sup. ported in an oil-tight casing 58. (2) The groove V in the matrix member M Fig. 25a, is inclined to the plane on which it is supported, and the tucking tool 310 is so moved in a supporting slide 308, Fig. 18, that the rit formed in the canvas C is inwardly inclined t( an insole body to which it may be subsequently attached to form a ribbed insole. (3) The vertically movable work-support 160 Figs. 6, 8, is presented alternately automatically at different heights to compensate for the increased thickness of the work when the matrix M is reversed after canvas has been applied to one face, i.e. between successive operations. (4) A core piece having a thick portion R, Fig. 25a, and a thin portion N is fed over the fold made by the tucking tool, independently of the matrix, and the feed foot 420, which is moved, in an elliptical path with its major axis inclined to the vertical by a pair of eccentric members, 434, 464, Fig. 10, forces the core into the fold and advances the work to operate progressively round the matrix. A flange is formed on the core piece N by wiping it inwardly of the edge of the matrix, by a ridged portion of the work-engaging face of the feed foot while the work is being fed. A wiper 480, Fig. 18, also operated from the barrel-cam, may be provided to smooth down the flange of the core piece N and draw it inwards of the matrix to cause the rib formed by the fold of the canvas and core piece to be drawn against the inner wall of the groove in the matrix face. A blast of hot air may be directed by a blower towards the region where the tucking operation is progressing to render the canvas limp if it is stiffened with resin or other thermoplastic material.

Title: Process for fixing dyestuffs on cellulose-containing fabrics and foils
IPC: D06P5/00
Filed: 1952-12-18
Abstract: Sparingly soluble to insoluble dyestuffs are fixed on cellulose-containing fabrics or foils by padding or printing the fabric or foil with a water-soluble acyl derivative of the dyestuff containing a water-solubilizing group in the acyl residue, and then hydrolyzing-off the acyl residue by treatment with an alkaline medium containing hydrogen peroxide or a water-soluble peroxide compound, such as sodium or potassium peroxide or alkalimetal percarbonate or perborate, capable of liberating hydrogen peroxide in aqueous alkaline media.  The acyl derivative is applied in a paste containing, for example, starch-tragacanth thickener, thiodiglycol and urea.  The hydrolysis bath may contain alkali-metal acetates, orthophosphates, carbonates, bicarbonates and hydroxides, ammonia or water-soluble amines such as ethanolamine, and saltingout substances such as sodium chloride, sulphate or carbonate.

Abstract: 631,595. Automatic temperature control systems. P.A.M., Ltd., and HOLT, H. B. W. Oct. 30, 1946, No. 32185. [Class 38 (iv)] [Also in Group XXXVII] Temperature is accurately controlled by minute actuation of contacts having a low A.C. voltage thereacross which, below the desired temperature, is amplified and rectified by thermionic valves and operates through a relay, a heater element switch. Fig. 2 shows a thermo-sensitive switch comprising a tube 4 and inner expansible rod 6 adapted to engage a contact 7 in a block 12 finely adjustable lengthwise along a housing 10 by a screwoperated stud bearing on a metal strip extending between the block 12 and a fixed block 11, to adjust the temperature controlled. The contact faces of 6, 7 may be polished and plated, and the tube 5 threaded at 26 for insertion, say in the cylinder of a thermo-plastic moulding machine. The amplifier may comprise a potentiometer R<1>, R<2>, Fig. 1, across the A.C. heater of a valve V<1> to the tapping of which the valve grid is connected, the voltage developed being rectified by a diode of the valve and used to block a second valve V<2> in the anode or cathode circuit of which is a relay 1. On the temperature rising the contacts 6, 7 meet and the grid of V<1> earthed, the diode ceases to function and V<2> is unblocked to energize the relay and switch-off the circuit x, y of a heater resistance. Alternatively, Fig. 3 (not shown), the rod 6 is of low expansion relative to an expansive enclosing tube and permits tilting of a lever, controlled by a preset screw and spring, to actuate a spring contact switch, the lever being carried in a tube at rightangles to the element. In Fig. 4 (not shown), the switch comprises a pair of bimetallic strips.
