Abstract: 524,031. Metal-vapour rectifiers. PATENTVERWERTUNGS GES. HERMES. Jan. 19, 1939, No. 1936. Convention date, Jan. 19, 1938. [Class 39 (i)] A metal vapour rectifier having a metal wall and laterally attached anode arms disposed obliquely to the surface of the vessel wall, has a tapered metal member interposed in the acute angle formed between the anode cylinder and the metal wall. In the Figure, the anode cylinder 2 having mutually parallel cooling ribs 4 disposed substantially perpendicular to the wall 5 of the vessel, extends through an aperture in the wall 5. The lower half of the aperture is joined to the anode cylinder, for example by welding, and the upper half of the aperture is enlarged so that it does not engage the cylinder. The tapered metal member 6 is joined to the edge of the aperture and to the anode cylinder. The strip has a cooling rib 7 which directs air on to the ribs 4 as shown by the arrows in Fig. 1. A cooling rib 8 on the part of the anode projecting inside the vessel is also provided. The welded parts are thus readily accessible and any great accumulation of metal is prevented.

Title: Improvements relating to Tractor Braking Systems
Inventor: GREEN MARTIN
IPC: B62D11/08
Filed: 1967-01-16
Abstract: 1,181,301. Differential braking for steering. GIRLING Ltd. 16 Jan., 1968 [16 Jan., 1967], No. 2140/67. Heading B7H. [Also in Division F2] A system for selective braking of one of two vehicle wheels, e.g. to assist steering of an agricultural tractor, comprises a control valve and a selector valve in a line between a fluidpressure source and the brakes, the selector valve being operative to increase the pressure transmitted by the control valve. The operation of the selector valve may cause the control valve to boost the pressure or may cancel a normal reduction in pressure. In a first embodiment a control valve 6 (Fig. 2) is included in the line (Fig. 1, not shown) between a master cylinder and the selector valve. This valve 6 contains a stepped piston 13 normally biased to the right by a spring 14 so that a valve-ball 16 is held off its seat by a stem 18, allowing flow of fluid from inlet 11 to outlet 12 through passages 19 and 20. When the inlet pressure rises sufficiently to move the piston to the left, the valve closes and the outlet pressure is increased by the ratio of the stepped piston areas. When the selector valve is in its neutral position to allow equal braking of the two wheels, a disc (22 in Fig. 1, not shown) abuts the outside end of piston 13 to prevent it moving to the left and thus prevent the presssure increase. In a second embodiment (Figs. 3 and 5, not shown) the selector valve in its neutral position locks the piston of the control valve by means of balls (32) engaging an annular recess (31) in the piston. When the selector valve is operated the balls move outwardly into one of two annular recesses (37) in a sleeve (36) around the piston. In a third embodiment a pressurereducing valve (Fig. 7) comprises a piston 13 attached to a valve 16A whose seat 17 is on a second spring-loaded piston 13A. When pressure is applied to the inlet 11, the piston 13 moves to the right and closes the valve. Increase in pressure at the outlet 12 is less than that at the inlet by the action of the spring 14 and by the movement of piston 13 to the right. The selector valve carries a disc 22 with a hole that normally permits the piston 13 to pass through it. When the selector valve is operated, the hole moves out of alignment with the piston and the disc 22 prevents it moving to the right. The selector valve (Fig. 4, not shown) comprises a disc (43) movable against one or other valve-seat (46) to block the passage of fluid from the inlet (43) to one or other of the outlets (42). It may be connected to the control valve by hydraulic or electromechanical means.

Jackets and covers.-In tyre covers of the " cord " type, the cord 4.is laid obliquely across the mandrel and looped round two side rings 11, and is arranged so that the parts forming a loop overlap at the loop 5 as shown at 6, and gradually diverge as shown at 7, 8 so that they lie side by side at the tread, in order to compensate for the variations of diameter over the cross-section of the tyre. The rings 11 may be of suitable material, such as metal wire or textile cord, to form the tyre beads or retaining-rings, and more than one layer of cord may be used, the cords in adjacent layers lying in opposite directions. In a modification, tapes formed of a group of cords may be used. In this arrangement, the tapes may overlap continuously from side to side, but to a gradually decreasing extent from the edges to the tread. The oblique position of the cord may be obtained by winding the cord transversely round the side rings which are then shifted relatively to each other.

Abstract: 828,793. Typewriters &c. RUF-BUCHHALTUNG A. G. Jan. 24, 1956 [Jan. 29, 1955], No. 2382/56. Class 100(4) A front attachment for typewriter, by the movement of a hand lever, feeds an account sheet until a mark made on the last line typed is sensed. A journal sheet is passed around a platen and the account sheet is inserted in a hopper 12 and is fed to the typing disc position, as determined by a punched mark, by control wheels 21, Fig. 4, on a driving shaft 23 on the movement of a lever 25 connected to the shaft 23 through an adjustable coiled spring drive, a drive disc 30, and pinions 31, 33, 34. A mark is punched on the account sheet by a plunger 40 engaged by a cam 49 when a lever 35 is rocked to effect carriage return after a line has been typed. The lever 35 also effects line spacing of the platen 50 through a push rod 57, two-armed lever 56 and pawl 52 while the push rod 57 also through a projection 65 on a yoke which pivots a pin 61 moves a lug 66 and thus a bell-crank 68 on an axle 69 to line space the account sheet. The axle 69 mounts an ejector pawl 72 and a locking pawl 73 and can be moved by a grip so that the latter can be inoperative. A pin 105 in conjunction with adjustable pins determines the movement of the lever 25 and hence the feed its actuation gives to the account sheet and it engages the edge 90 of a lug on a part 86 to cause it to engage a strip 97. When an account sheet is placed in the hopper 12 and the lever 25 is actuated to feed it to the printing position the pin 105 moves away from the part 86 allowing a spring 91 to move it away from the strip 97 so that its hook 98 projects into the path of the account sheet until a punched mark therein engages it pulling down the strip 97 to cause a lever 92 to engage a ratchet pinion 95 on the driving shaft 23 to stop its movement. The account sheet will have overrun by this movement and will be returned by a spring on the shaft 23, which is wound up by the initial feed, until the ejection pawl 72 positions the drive disc 30 correctly and hence the account sheet in the correct typing position. If the handle provided has been set to make the locking pawl 73 operative actuation of the carriage return lever 35 will punch the account sheet and feed it and the journal sheet a line space otherwise the ejection pawl will be withdrawn allowing the spring on the shaft 23 to return the parts and thus eject the account sheet. The part 86 protrudes so that it can be rocked to render the sensing device inoperative and a lever 77 is provided to manually eject wrongly inserted sheets. The control wheels 21 on the shaft 23 are adjustable for different form widths.

Abstract: 956,475. Moulding soles on to uppers. INTERNATIONAL VULCANIZING CORPORATION. Jan. 20, 1961 [Jan. 28, 1960; Sept. 16, 1960], No. 2413/61. Heading A3B. [Also in Division B5] An apparatus for moulding a sole on to an upper comprises a last having an upper U thereon, an open mould 8 having an injection opening, means for mounting the upper on the mould for relative movement thereto and means for resisting the relative movement. Means are provided for injecting a sole forming composition through the injection opening into the mould at a pressure above that of the means resisting relative movement and also means, e.g. a switch S, automatically operable by a predetermined relative movement of the last and mould to terminate injection. A constant pressure is maintained on the sole by the means resisting relative movement during setting. In the construction shown the mould is mounted and fixed on a table 16. The mould which is laterally movable has four gauge blocks 40 for centralising the lasted upper U in the mould. An air cylinder 18, the piston pressure of which is controlled by a regulator R and valve V, is mounted vertically above the table and mould. The two rods 22 and 24 protruding from the cylinder are extensions of the piston the former carrying a bar 26 to which is attached a heel abutment and a toe hold-down 30 while the latter is threaded at 36 to carry on adjusting nut 38 which limits the downward movement of the piston. The lasted upper is engaged by the heel abutment 28 of the bar 26 and the toe hold-down 30 and the plasticized material is injected into the mould through a nozzle 44 by a screw 48 rotated by a motor M. The screw is situated in a barrel 46 which is heated by a jacket 50 surrounding it. The pressure of the plasticized material lifts the lasted upper from the rim of the mould a predetermined amount whence the injection is cut off by the switch S engaging on a projection of the apparatus. When the mould is filled a tough skin is formed adjacent the wall of the mould. This skin does not rupture when the last lifts from the rim of the mould. The sole is then solidified by heating or cooling the mould. In a modification the lasted upper is fixed with respect to the mould and the base of the mould is free to move, the movement vertically being controlled by an air cylinder as above or by a spring. Also a last with a sprung base is disclosed, the base giving the predetermined movement while the main part of the last remains fixed with respect to the mould. Specification 763,847 is referred to.

Title: Improvements in or relating to synchronising devices
IPC: H04N5/04
Filed: 1931-01-24
Abstract: 377,240. Synchronous movements. FERNSEH AKT.-GES., Goerz-Allee, Zehlendorf, Berlin. Jan. 24, 1931, No. 2418. Convention date, Jan. 31, 1930. [Class 40 (iii).] The invention relates to a method of damping hunting oscillations in a continuously rotating device for television apparatus. Synchronizing impulses initiate the application of an accelerating torque when the device is slowing down and a retarding torque when the device is speeding up, immediately prior to phase coincidence of the device and the impulses. The theory is explained in the specification with the aid of curves. A form of apparatus to which the invention may be applied is shown in Fig. 1. A motor 10 is maintained at synchronous speed by impulses in an electromagnet 1 effecting contact of a pin 3 with segments 6 or 7 on a disc 5 rotated by the motor, thereby discharging condensers 13 or 14 through a relay coil 11 with the effect of inserting a resistance 21 in the motor circuit or shortcircuiting it therefrom. In order to damp the hunting inherent in this apparatus, the disc 5 is frictionally mounted on the motor shaft and the segments 5, 7 are provided with bevelled portions 22, 23, Fig. 3. If the motor is slightly fast, the pin by contacting with the bevel 23, forces the disc backwards relatively to the shaft, so that contact of the pin with the bevel 22 will occur before the phase coincidence. In apparatus where the impulses act through a magnet 30, Fig. 4, upon a La Cour wheel, slight displacement of the wheel relatively to the shaft, due to incorrect phase, causes closure of contacts 26 or 27 and displacement of magnet 30 by electromagnets 32 or 33. If the La Cour wheel is coupled to the shaft by a viscous fluid clutch, Fig. 6, the displacement of the wheel relatively to its shaft effects the advancement of the application of accelerating and retarding torques. Moreover the La Cour wheel may be the sole driving means, in which case it is coupled to the shaft by a spring.
