Filed: 1943-11-23
Abstract: 592,397. Electron oscillators ; automatic frequency control. WESTERN ELECTRIC CO., Inc. Nov. 23, 1943, No. 19589. Convention date, April 11, 1941. [Classes 39 (i) and 40 (v)] [Also in Group XXXV] In a velocity modulated oscillator of the reflex type, the gap is defined by two grids 34, 37, Fig. 1, which are dished in a direction away from the cathode, and the reflecting electrode 38 is dished in the same sense. As shown, the resonator consists of coaxial metal cylinders 40, 41 connected to discs 33, 35 sealed through the wall of the envelope 10 and provided with apertures closed by the mesh discs 34, 37. The resonator is tuned by an adjustable plug 43 and screw 44. The electron gun consists of an indirectly heated cathode comprising a cylinder 14 closed by a flat electron emissive disc 15, a focusing electrode 17 in the form of a sleeve 17, and an accelerating electrode in the form of a sleeve 19 with the end closed by a mesh disc 20 preferably dished towards the cathode ; all the parts are mounted as a unitary structure on a metal base 21 which is supported on rigid wires at the stem 11 of the envelope; In a modification, Fig. 4'(not shown), the envelope is a metal cylinder and the resonator is entirely enblosed therein, the discs forming the gap having a sliding fit in the cylinder and being clamped in position by sliding sleeves : tuning of the resonator is by a coaxial line of adjustable length. The oscillator may be coupled to a device for stabilizing its frequency as shown in Fig. 3. This consists of a resonator 70 tuned to the desired frequency by a screw 71, and coupled to the oscillator 10 by a coaxial line 75 and loops 75a, 76a, 76b. The lengths of the leads to the loops are such that the voltage at the loop 75a is 90 degrees out of phase with that at the loops 76a, 76b. The latter are connected by rectifiers 72a, 72b across a resistance 73, which in turn is connected across the input terminals of a D.C. amplifier 74. Variations in the frequency of the oscillator produces a variation in the output of the rectifier which alters the potential of the reflecting electrode 38 and restores the frequency.

Title: Improvements in and relating to tools for cutting off portions of screws or the like projecting from a surface
IPC: B26D5/18
Filed: 1944-10-13
Abstract: 585,237. Rod cutters. BOULTON PAUL AIRCRAFT, Ltd., NORTH, J. D., and CLARK, B. F. Oct. 13, 1944, No. 19745. [Class 61 (ii)] A tool for cutting off portions of screws or the like projecting from a surface comprises a locating boss 35 adapted to engage the end of the screw or the like to be cut, two or more cutting-wheels 31 carried by a support rotatable with or about the boss and means operable upon rotation of the support to force the cutting-wheels into the screw or the like. A sleeve pinion 15 mounted on a fixed shaft 16 is adapted tn be rotated from a handle 12 by a pinion 6 and drives a block 19 through dogs 18. Cranked levers 26 are pivoted to the lower end of a block 24 in screwthreaded engagement with the end of the shaft 16. The upper ends of the levers are connected by links 27 to the block 19 whilst the lower ends carry the cutting discs 31. The locating boss 35 at the lower end of the block 24 may be integral therewith, as shown, or may be rotatable relative thereto, in which case it will remain stationary during the cutting operation. As the block 19 is rotated, the discs 31 travel around the screw to be cut and are gradually moved inwards due to the screwing movement of the block 24 along the shaft 16. Instead of hand operation, the tool may be driven by an electric or other suitable motor. According to the Provisional Specification, the bell-crank levers may be operated by a yoke on a ring carried by a stationary threaded boss along which it moves when the locating boss is rotated. The ring may pass a dead-centre position so that the wheels move together to sever the screw and then move apart again, the tool being operated in the reverse direction at the next screw to be cut. Alternatively, if the tool is driven by an electric motor, a switch may be provided to reverse the direction at the end of each cutting operation so that the wheels aro returned to the starting position.

Filed: 1922-07-18
Abstract: 207,220. Mills, F. A. July 18, 1922. Spray carburettors.-Air is drawn through an auxiliary duct to mix with fuel, discharged from a main submerged jet orifice, and carry it laterally into a secondary passage whence it is discharged into the main air stream. The air passage A<1> of the straight-through type is controlled by a piston valve B actuated by a cable B<4> against a spring B<5> and carries a needle valve B<1> which controls the submerged main jet orifice D. Above this orifice is a centre piece C having an axial bore C<5> for the needle valve and two parallel passages C<2>, C<3> of which C<2> is open to the outside air through a tube C<6> and C<3> opens into the main air passage A<1> through a duct C<4> preferably inclined. The arrangement of the passages is such that air through the duct C<2> carries the fuel from orifice D laterally into the auxiliary passage C<3> whence it is discharged into the main air stream. The needle valve may be adjusted independently by a screwed rod B<2>. The space A<2> formed between the head C' of the centre piece and the body of the carburettor, forms a well into which fuel can be discharged, by depressing the float E<2>, through the passage C<3> to facilitate starting. The jet body D<1> is screwed into the centre piece and a nut E<1> retains the float chamber in position. In a modification the duct C<2> is dispensed with, a passage conveying air from the main passage A<1> to the central bore C<5>. more than one air duct may be provided and such ducts are not necessarily formed in the centre piece C.

Title: Improvements relating to the depositing of cream and like centres
IPC: A23G3/02
Filed: 1948-07-23
Abstract: 650,345. Endless-belt conveyers. TUNLEY, A.A., BAKER PERKINS, Ltd., and ANCIENS ETABLISSEMENTS A. SAVY, JEANJEAN, ET CIE. July 23, 1948, No. 19793. [Class 78 (i)] In a plant for depositing cream and like centres in starch moulds contained in trays, the trays are transferred from one depositing unit and spaced to permit pusher elements associated with a second depositing unit to engage the backs of the trays and move them into depositing position. An endless conveying surface 7 provided with dogs 8 is driven in long intermittent steps to feed trays into the zone of synchronized pushers 4 associated with the conveying surface 1 of a first depositing machine. Surface 1 is moved in short rapid steps so that the depositing nozzle 17 is positioned over each of the mould depressions 6 in each tray in succession. Surface 7 is timed to move the tray T20 into the path of pusher 4 as the last deposit in tray T22 is being made, after which pusher 4 makes a stroke to move tray T20 to the first deposit position. For feeding to the conveying surface 2 of the second depositor an endless surface 9 provided with dogs 10 is driven in synchronism with the surface 7 and thus the feeding to the depositor nozzle 18 is identical with that above. In order to space the trays to allow the dogs 10 to engage them a roller 14 is provided having a flat 16 on it and arranged to be driven one revolution in synchronism with the long movement of surface 9 such that at the beginning and end of the rotation flat 16 is at the bottom. This allows the tray T24 to pass underneath roller 14 as the moulds 6 in tray T20 pass below nozzle 17. When T20 is halffilled roller 14 which is spring-loaded presses the tray T24 against surface 9 while rotating one revolution, after which the tray is in a position to be engaged by a dog 10 ready for feeding to the pusher 5 of the second depositor.

Abstract: 1,271,686. Welding by fusion. MESSER GRIESHEIM G.m.b.H. 18 April, 1969 [20 April, 1968], No. 19865/69. Heading B3R. [Also in Division F2] In gas-shielded consumable wire electrode arc welding, wherein first rollers 15, 16 draw electrode wire 10 from a storage reel and push it into a flexible hose (not shown), and second rollers 17, 18 pull the wire from the hose and feed it to the arc, the drive to each of the first rollersis via an adjustable slipping coupling 31 so that a predetermined pushing force corresponding to the buckling load of the wire is not exceeded, and wire ejection in jerks or undulating form is prevented. The pressure of the second pulling, rollers on the wire may be adjusted to permit slip. As shown, both first and second rollers, together with their drives, are housed in suitcasetype boxes 20 provided with handles 19, connections for cooling water inlet and outlet and shielding gas pipes, and wire drive motor speed control knobs. Both sets of rollers are driven, through gearboxes 30, by D.C. shunt wound or electronically or mechanically controlled, frequency-controlled synchronous or asynchronous motors 28. In the first set, 15, 16, only, the drive from the gear-box to each of the rollers is via a slipping coupling 31 which comprises a friction disc 40 gripped between a driven roller 15 or 16 and a driving disc 36 keyed to, for axial movement on, a gear-box-shaft-fast sleeve 33 and acted on by cup springs 38 reacting on an adjusting nut 39. In Fig. 2 (not shown), the second rollers (17a, 18a) are housed in the welding torch, their driving motor being disposed inside the torch handle. In a further alternative embodiment, a third set of rollers, torch mounted, may be added to the arrangement shown, the second set of rollers then having both pulling and pushing roles.

A printing blanket for use in screen printing, which is a vulcanized, endless, unitary structure, comprises a loop of a base ply of textile material, e.g. duck, a layer of substantially unstretchable cord, e.g. glass yarn, in the form of a continuous length wound longitudinally of the loop as an helix enclosing the entire loop of the ply and at least one ply of textile material covering the cord layer, the or each covering ply and each turn of the cord being surrounded by and embedded in a vulcanized rubber. Each turn of the cord save for its rubber embedment lies in immediate proximity to the base ply and, instead of one length of cord enclosing the entire loop, two lengths may be employed which extend, respectively, as left-hand and right-hand windings from the centre of the base ply to its margin. In the embodiment shown, a base ply 12 of duck carries a rubber coating 13. Two helices 14, of rubber-coated rayon or glass yarns, having right-hand and left-hand windings, are wound on the top of the coating 13. The covering duck ply 15 is rubber coated on each face whilst a further duck ply 19 carries a rubber coating 18. If required, the top surface of the ply 19 carries a rubber coating 21 which later becomes the working surface of the blanket. The assembly of plies and yarns is vulcanized in a press the heat and pressure of which is such that in the resulting blanket the rubber layers are indistinguishable and form a solid rubber mass in which all of the fibrous elements, whether yarn or fabric, are embedded. The coatings 13, 16, 17, 18 and 21 and the coatings of the rayon and glass yarns may be a vulcanizable neoprene or a butadiene acrylonitrile rubber compound.

Title: Method of separating mists from gases and vapours
Inventor: SCHYTIL FRANZ
IPC: C01B17/76
Filed: 1952-08-08
Abstract: Gases and vapours other than those treated in the parent Specification are freed from mist by passage through filters at a higher speed than corresponds to the break point in the logarithmically plotted pressure drop-speed diagram.  In an example a horizontal filter 10 mm. thick, of solid particles with a porosity of 55 per cent and a mean capillary diameter of 100 microns is saturated with sulphuric acid and gas containing 20 gm. sulphuric acid per cubic metre is passed through at increasing amounts per hour.  The break point is found to be about 37 cubic metres per hour and at 50 the limit of visibility of mist in the outgoing gas is reached, i.e. 100 mgm. per cubic metre.  A pressure loss of at least 200-250 mm. water column is necessary to effect 96 per cent separation.  With larger pored filters the material may be sprinkled with the same or different liquid, or liquid may be sprayed into the mist and separated with it.  By spraying with 1 litre of water per cubic metre of gas in one example the pressure loss of the filter is increased from 100 to 300 mm. water column and the separation from 80 to 98 per cent. Porous ceramic or fritted materials, fritted glass bodies, fabrics, felted fibres, &c., may be used and liquid forced through the pores and collected may be redistributed over the inlet side of the filter which may be operated at elevated temperature. Application of the process to sulphuric acid and concentration plants is referred to.
