J., 10, Studentgatan, and CLEMENTSON, C., and CLEMENTSON, S., (trading as CLEMENTSON, C. & S.), 50, Kalbrottsgatan, Limhamn, both in Malm÷, Sweden. June 16, 1934, No. 17867. [Class 7 (ii)] [See also Group XXXIV] A mixture of lubricant and additional air is drawn into the induction pipe by the vacuum therein. A device 1, which may be mounted upon the instrument panel of a motor car, has a plug cock 8 which can be set in two positions A, C, determined by adjustable stops 23, 24. In the position C a diametral passage 7<1> in the plug 8 opens communication between a pipe 2, dipping in an oil reservoir 3, passages 7 in the lubricator 1, a glass tube 14, and a pipe 4 leading to the intake manifold 5. The passage 7 is connected by a passage 9 to a spring-urged air inlet valve 11, Fig. 4, the seat of which is formed in an adjustable plug 13. In this position, which corresponds to the starting-up position, oil is drawn up the pipe 2 and air enters through the valve 11, the mixture passing through the tube 14 and pipe 4 to the engine. When the engine is running normally the plug cock is moved to position A so that in addition to the above connections an angular passage 16<1> in the plug 8 connects a chamber 17 to a passage 16 leading to the tube 4. The chamber 17 is controlled by a vacuum relief valve 20. Should the suction in the manifold 5 exceed the setting of the valve 20 the latter opens and extra air passes therethrough and mixes with the mixture passing through the pipe 4. At an intermediate position B of the plug cock both passages 7<1>, 161, are shut off.

IPC: B29D30/36
Filed: 1919-07-18
Abstract: 142,368. Hopkinson, E. July 18, 1919. Tyres, elastic, special apparatus for making.- Covers for pneumatic tyres are formed from a flat endless band by applying pressure through an expansible wall to small portions of the band along its centre line, and then causing said pressure to act successively at all points along the said centre line throughout the circumference of the band. The forming disks 25 are mounted between two spaced drums A, A', each formed in four segments. The segments of the drum A are supported by arms 2 slidably held within pockets 3 in a cruciform block 4 loosely mounted on a shaft 1 and resting upon a collar 5 thereon. For the expansion or contraction of the drum A, each arm 2 carries a pin 6 projecting upwardly into a slot 7 in a cam-disk 8 revolubly mounted on the shaft 1 and operated by a handle 9. The drum A may be held in its expanded position by a pin 10 passing through the disk 8 and engaging a slot in the block 4. The segments of the drum A<1> are carried by slides 11 movable in a channel 12 formed in arms 13 projecting inwardly from a carriage 14 provided with rollers 22 running on a circular track 24 on the frame B. The slides 11 have pins 15 projecting upwardly into slots 16 formed in a cam ring 17 adapted to be moved by a lever 18 to contract or expand the drum A<1>. The forming disks 25 having an outer surface conforming with the desired shape to be imparted to the tyre are carried by shafts 26 mounted on levers 28, which are pivoted on shafts 29 carried by a base-plate 30 supported on by arms 31 on the frame B. Studs 32 on the outer ends of the levers 28 are maintained bv springs 34 in contact with a cam-ring 33 operated by means of a rack 33<x> and a gear-wheel 35<x> from the main shaft 1. The ring 33 is formed with active faces c and retarding faces d meeting in a rounded apex, the faces c swinging the disks 25 outward, and the springs 34 and faces d returning them to their original positions. The shafts 26 carry pinions 41, which are driven by pinions 40. 42 from the shaft 1. The operation of the machine is as follows :-The. band E with an expansible band F is placed on the drums A, A<1>, which have been contracted as described, and is centred bv blocks 11<1> secured to the drum A<1>. The drums A, A<1> are then expanded and the shaft 1 rotated. The disks 25, which are in contact with the band, are then moved outwardly, the movement of the levers 28 and the pinions 41 causing the disks to contact successively with the whole of the band distending the latter as shown in Fig. 3 until the side edges of the band are at right-angles to the initial position of the band. When the rollers 32 riding along the faces d of the cam-ring reach the bottom of the notches in the said ring, the cycle of operations is completed and the formed casing removed.

Title: Improvements in automatic volume control devices in radio pulse receivers
IPC: H03G3/22
Filed: 1942-12-18
Abstract: 576,103. Automatic gain control. GENERAL ELECTRIC CO., Ltd., and CHERRY, E. C. Dec. 18, 1942, No. 18050. [Class 40 (v)] In a wireless receiver designed for signals consisting of short pulses of carrier-frequency energy, automatic gain control is effected by use of part of a tuning indicator tube of the cathode-ray type as a D.C. amplifier of the rectified potential from a diode detector. The diode V4 is fed with pulses from an anode bend rectifier valve V2, via condenser C3 and resistance R4. The D.C. potential appearing across the diode load, comprising resistance R and capacitance C, is applied between grid and cathode of the tuning indicator tube V3. The gain control voltage for the early stages of the receiver is taken off across a resistance R2 connected in the cathode lead of the tube V3, a suitable standing bias being maintained by connecting the lower end of the resistance R2 to a source of negative potential. The ganged switches S1, S2 are arranged to be normally open, so that AVC is operative ; on closing the switches, the AVC is put out of action and the tuning indicator target T connected in circuit.

Title: Improvements in combination locking devices
IPC: E05B37/16
Filed: 1919-07-18
Abstract: 152,763. Hazelton, G. July 18, 1919. Locks, permutation.-Relates to locking-devices for securing parts having relative rotary movement, as in valves and cocks, electric switches, steering-gear &c., and consists in a permutation mechanism having a number of elements of which certain members, which have been previously set by reversal from their normal position, have alone to be operated. Figs. 1 to 3 show the arrangement in connexion with a valve. A plate 13 moving with the spindle 8 is formed with an interrupted rib 14, which in the position shown in Fig. 2, clears projections 20, Fig. 3, on spring plungers 17, guided in the casing. The plungers are formed with projections 20 nearer to one end than the other, so that if, when assembling the device, certain of the plungers be reversed, end for end, the projection 20 on each of such plungers is in position to lie in a gap 15 of the rib 14. The spindle cannot then be rotated unless these selected plungers are pressed in, so as to release them from engagement. Should any plunger that has not been reversed be pressed in, it will come into the locking position, and give additional security. The plungers may be arranged vertically instead of horizontally. The device is shown fitted to a cock having a cork seating 2, with ports 3, 4, with which ports 9, 10 in a disk part 7 moving with the spindle 8 can be put into register, a concentric channel 11 then providing a through passage. The cock can be dismantled, and the combination re-set, by removing the nut 24, after withdrawing a screw 27, which is accessible through openings in a boss 26 only when the tap is on. The locking-device is applicable also to plug-cocks.

Abstract: 1,039,884. Velocity-modulated tubes. SIEMENS & HALSKE A.G. May 8, 1963 [May 9, 1962], No. 18128/63. Heading H1D. A velocity-modulated electron tube, e.g. a travelling-wave tube, backward-wave oscillator or a klystron, includes a cathode for emitting electrons, a catcher for receiving electrons from the cathode, means for providing a magnetic field to guide electrons along a path from cathode to catcher and a gettering device in the form of one or more additional electrodes located near to the path and arranged to attract and absorb ions produced by collision of an electron from the cathode with a gas molecule within the tube. In one form, Fig. 1, a travelling wave tube has an anode 6 and Wehnelt cylinder 3 of the electron gun producing a radial field for ions 10, 10<SP>1</SP> which impinge at high velocity upon the Wehnelt cylinder, thus releasing atomized getter material of which the cylinder is formed. The getter material is collected on the anode and the ions absorbed by the active surface formed thereon. Alternatively, Fig. 5, the ions are deflected through a perforated cylinder 8 under the action of a radial field formed between the cylinder and co-operating electrode 9, the ions being absorbed on an active surface produced on the diaphragms 6. In a further embodiment, Fig. 2, the gettering action occurs near the electron catcher, a perforated cylinder 13 being provided adjacent the beam 1. The perforated cylinder in all the embodiments may comprise a wire mesh gauge or a coil of wire. Suitable gettering material is tantalum, columbium, zirconium or titanium.

Title: Improvements in adjustable reaming tools
IPC: B23D77/04
Filed: 1920-07-02
Abstract: 146,461. Schumacher, H. July 8, 1919, [Convention date]. Reamers; cutter-bars.-In an adjustable reamer or boring head for cylindrical work designed to avoid chattering a plurality of spring- pressed blades 6 are attached to double-armed levers 8 pivoted at 9 to bolts 10 secured by detachable pins 11 to the body 4 of the tool. The free ends of the levers have screws 14 which mav be adjusted according to the diameter required. A sleeve 15 on the tool spindle carries the pivots 17 of a number of rods 18 guided between pairs of rollers 19, 20 on the reamer body. On turning the sleeve by means of a handle 16 the rods assume a radial position and coact with lateral arms 21 on the levers 8 to lift the blades clear of the work on completion of the operation. In a modification the sleeve 15 carries a toothed rim engaging a number of bolts passing through the reamer body. The central portion of these bolts is eccentric and supports small thrust bolts, the other ends of which bear against the adjusting screws 14. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a further modification, Fig. 5 (Cancelled), suitable for large motor cylinder bores and in which alternate blades are replaced by wooden centring-blocks 50 controlled independently of the blades. The sleeve 15 is replaced by two loose toothed rings 32, 51 and one of the eccentric bolts 24 is carried by a shaft 23 the upper end of which has an arm 60 carrying a conical roller 61. When the blades reach the cylinder-head, the roller contacting with the edge 62 of the cylinder causes the arm 60 to swing, thus rotating the shaft 23 and the ring 32 to withdraw the blades. The centring-blocks are similarly adjusted by the bolts 53, one of which is carried by a shaft 52 adjustable by a nut 54 and held in the required position by a suitable locking-device. This subject-matter does not appear in the Specification as accepted..

Title: Apparatus for winding a strand
IPC: B65H54/28
Filed: 1962-05-14
Abstract: 947,415. Winding strand material. PITTSBURGH PLATE GLASS CO. May 14, 1962 [May 25, 1961], No. 18406/62. Heading D1J. A winding apparatus for strand material 30, Fig. 2, comprises a traversing mechanism 35 guiding the strand on to a rotating take-up tube 28, the traversing mechanism 35 and the tube 28 being coupled to means whereby they are reciprocated simultaneously in mutually opposite directions as indicated by the arrows. The strands 30 may be glass filaments 26 that are sized by an applicator 34 and then passed through a guide 32 that is so positioned as to maintain the strands 30 in a sinusoidal groove 38 formed in the reciprocating and rotating traversing mechanism 35. The applicator 34 and guide 32 may be reciprocated with the traversing mechanism 35. The applicator 34 may be replaced by a saturated felt pad in the guide 32. Reciprocating motion. According to one embodiment Fig. 3, a stationary support 85 carries a pivot 107 on which is mounted a bell crank lever 106. A reciprocating carriage 50 carries the tube 28, a motor to rotate the tube, and an inclined bar 100 acting as a cam that engages the end 104 of the bell crank lever 106 to rock it as the carriage 50 reciprocates. The arm 110 of the bell crank lever 106 is coupled to and reciprocates a plate 87 carrying the traversing mechanism 35 and a motor (not shown) for rotating the traversing mechanism. A tension spring 125 maintained the roller 104 of the bell crank lever 106 in engagement with the cam 100. As the carriage 50, and thus the tube 28, move to the right the plate 87 and thus the traversing mechanism 35 move to the left and vice versa. The inclination of the bar 100 is adjustable to vary the throw of the plate 87. The bar 100 may be replaced by bars of different shape. In Fig. 6 the bar has a horizontal portion 101a so that the plate 87 is not reciprocated whilst the roller 104 is running on the surface 101a, the surface 101a being used whilst the tube 28 is being moved from a start-up position for winding waste to its normal reciprocating positions. In Fig. 7 the bar 102 has its ends shaped to increase the axial speed of the traversing mechanism 35 whilst it is depositing strand at the ends of the forming package to prevent the building of ridges at the end of the forming package. Shaped packages. Fig. 9 (not shown) illustrates a modification in which the reciprocation of the winding tube again causes an inclined cam bar to act on the roller 104 carried by the bell crank lever 106. The reciprocating motion of the winding tube also causes a roller to strike a cam surface in a manner actuating a ratchet mechanism in a step-by-step manner, the ratchet mechanism being mechanically coupled to the inclined cam bar such that the inclination of the bar is reduced in a stepby-step manner. This lowering of the cam bar reduces the throw of the plate 87, carrying the traversing member 35, to form a package with tapered ends. Specifications 909, 154, 947, 414 and U.S.A. Specification 2, 607, 197 are referred to.
