Patent GB-1084733-A (GB)
Title: Electric control apparatus
Inventor: HAMMOND RICHARD
IPC: B65H23/18
Filed: 1963-03-14
Abstract: 1,084,733. Electrical control systems. ENGLISH ELECTRIC CO. Ltd. March 13, 1964 [March 14, 1963], No. 10225/63. Heading G1N. In the controlled transfer of sheet material from one drum 12 to another 11, the amount of material on each drum is represented by the positions of potentiometer sliders 20, 21, and when the amounts are equal to winding process is decelerated automatically. The linear strip speed, measured at 28 by a tachogenerator 26, is applied to an input of a differential amplifier 24, whose other input is from the self-balancing potentiometer 18 connected across another tachogenerator 16 measuring the angular speed of the take-up drum 13, the latter speed depending upon the outer radius of the coiled material. The tapping 20 on the potentiometer 18 is driven by the differential amplifier 24 output and its resultant position, representing the difference between the two speeds, hence indicates the radius of the coiled material. The tapping 30 of a square law potentiometer 32 is mechanically linked to the tapping 20, and a second tapping 34 is preset to the radius of the drum 13, so that the signal applied to a comparator 36 represents the difference between the squares of the inner and outer radii of the material coiled on the drum 13, and hence represents its volume. A similar circuit arrangement supplies the volume of the unwinding coil of material 12 to the comparator 36, which produces an output signal only when the two volumes are equal. A gear-box 37, driven by a tachogenerator 27, moves the tapping 38 of an integrating potentiometer 39 so that the output of the tapping 38, applied to a further comparator 40, represents the volume of material already transferred. When the comparator 36 produces an output, indicating the half-way stage in the winding process, the drive from the gear-box the tapping 38 is reversed. When the value of the tapping 38 voltage drops below that of the output of a tachogenerator 41, which is driven by the uncoiling drum and has its field excited from a strip velocity tachogenerator 43, the comparator 40 produces an output. This operates a deceleration device 15 which brings the winder to rest with only a few anchor turns left on the unwinding drum. If the two drums have equal radii the square law potentiometer may be replaced by a linear one. Instead of the potentiometer 39, a digital measuring device may be used.

Title: Improvements in or relating to adjustable wheel suspensions
IPC: B62D17/00
Filed: 1948-04-14
Abstract: 652,434. Vehicle spring suspensions. THOMPSON PRODUCTS, Inc. April 14, 1948, No. 10348. Convention date, Nov. 22, 1947. [Class 108(ii)] In a vehicle steering wheel suspension wherein the swivel joints secured at the outer ends of upper and lower arms are capable of adjustment to regulate camber and caster angle, the arms are connected to the wheel carrier by ball joints and the effective length of the upper arm may be varied to regulate camber, whilst the lower ball joint may be pivoted about the upper ball joint to regulate caster angle. As shown in Fig. 1, the wheel spindle 11 is integral with a steering knuckle 12 supported by ball joints 14, 15 from upper and lower arms 16, 29. Each arm is U-shaped in plan. The two ends of the upper arm 16 are secured to the ends 19 of the spindle of the shock absorber 18, and to the base 16c of the U is welded a housing 24 in which is screwed an adjustable bush 36, see Fig. 3. The bush 36 is internally screwed to receive the threaded shank 25 of the ball housing 14. The threads on the interior and exterior of the bush 36 are of opposite hand, so that when the bush is turned by means of the hexagon 36a the effective length of the arm 16 is altered to vary the wheel camber. The bush is split longitudinally and is held in position by a clamping bolt 39, Fig. 4, the housing 24 also being split as shown. The screw threads do not extend to the outer ends of the housing, 24, bush 36 and shank 25, these parts being provided with plain surfaces, as at 25a, to receive lateral shocks due to road inequalities. Rotation of the ball housing 14 when the bush rotates is prevented by a tongue 38d which engages in a slot 25c in the ball housing. Caster angle is adjusted by slacking off a clamping bolt and turning the hexagon 40a, Fig. 1, of a bush similar to that shown in Fig. 3 except that the interior and exterior threads are of the same hand, so that no longitudinal displacement of the ball joint 15 takes place, and that the shank of the ball housing 15 is located eccentrically in the bush. Thus rotation of the bush by means of the hexagon 40a moves the ball joint 15 forwardly or rearwardly, the wheel carrier 12 pivoting about the upper ball joint 14. Fig. 10 shows a modified clamping arrangement. The bush 47 is screwed into the housing 16c and receives the screwed shank 46b of the ball housing 14 as before; the housing 16c in this case is formed with a threaded conical spigot 16e, longitudinally split along its upper portion to receive and guide a tongue 51 formed on the shank 46b to prevent rotation of the ball housing 14, a conical nut 45 contracts the split spigot 16e on to the shank 46a. The screwed bush 47 is formed with flats 47a to facilitate adjustment. The lower ball housing 15 is mounted eccentrically and is fixed in its adjusted position by means of a nut 57 screwed on to a similar threaded conical split spigot 29d. Bumper plates 60 and 61 are attached to the upper and lower arms to engage resilient bumper members 58, 59 secured to a frame member 21, Fig. 1.
Patent GB-1065945-A (GB)
Title: Improvements in or relating to magnetrons
IPC: H01J25/44
Filed: 1965-03-15
Abstract: 1,065,945. Magnetrons; travelling-wave tubes. SFD LABORATORIES Inc. March 15, 1965 [March 13, 1964], No. 10893/65. Heading H1D. A magnetron or a crossed-field travelling- wave tube with a cylindrical cold cathode or cathode sole and a surrounding circular or part-circular anode wave circuit has a permanent magnet within the cathode or cathode sole and inside the envelops for generating the magnetic field. The cathode end hats form polepieces for the magnet. The invention is described as applied to a noise generator with a non-re-entrant interdigital wave circuit in which the fingers are bifurcated to introduce inductive loading. A built-in, short-circuited coaxial output line, extending parallel to the axis of the tube, is connected to the wave circuit by a radially extending finger between the inner conductor of the line and the end segment of the wave circuit. The cathode may operate with high field emission in which case H 2 , A or Xe gas is introduced at a pressure of 10<SP>-1</SP> mm. Hg., or the cathode may be secondary emissive. Heat is conducted from the magnet via the cathode structure support stem to an external heat sink, but the magnet is radially spaced from the inside wall of the cathode emitter to reduce thermal conduction from the cathode to the magnet. The invention may be applied to a forward or backward wave amplifier tube or to a strapped magnetron oscillator with a reentrant wave circuit.
Patent GB-586287-A (GB)
Title: Improvements in or relating to inertia devices for controlling wheel slip incident to braking or the like
IPC: B60T8/74
Filed: 1944-05-30
Abstract: 586,287. Brakes. STEVENS, A. H. (Budd Wheel Co.). May 30, 1944, No. 10396. [Class 103 (i)] [Also in Groups XXVI and XXXV] An inertia device for detecting the rotary condition of a member, e.g., a wheel during a braking-operation, is driven by flexible means which permit the device to lead or lag relatively to the member, the said lead or lag being used to control a brake-cylinder. As shown, the inertia member 17 is journalled on a boss 19 projecting from the casing 10, and is driven from the axle 21 by a crankshaft 23 having an arm 27 in driving relationship with flexible strips 30, 31 attached to the member 17 at 32, 33. The arm 27 has bifurcations carrying abutments 28, 29 which bear on the outsides of the strips 30, 31 at points adjacent to abutments 35, 36 secured to the member 17. A spring 38 keeps the strips normally in contact with the abutments 35, 36. If the deceleration becomes excessive, denoting wheel slip, the inertia effect is such that one or the other of the strips 30, 31 is flexed away from its associated abutment 35, or 36, so that contacts 46 on the affected strip, bridge conductor rings 40, 41 to complete a circuit which, as described below, results in the brake-cylinder being vented to allow the wheels to accelerate to vehicle speed. In Fig. 8, the brake-cylinder 96 is supplied with pressure fluid through the pipe 97, electro-magnetic valve 98 and pipe 111. When the coil 107 is de-energized, the spring 109 keeps the valve 105 open and the valve 104 shut. The inertia control device 95 acts, under excessive deceleration, to excite the solenoid 116 which closes the contacts 122, 123, 124 to energize the coil 107. This closes the valve 105 and opens the valve 104 to permit the brake-cylinder to vent through the port 108. The wheel then accelerates and the inertia effect of the member 17 flexes the strips 30, 31 in the opposite direction, the rings being again bridged by the opposite contacts 46. To prevent the solenoid 107 from becoming de-energized during the change from deceleration to acceleration, a dash pot 126 is provided, the rate of return of the piston 127 to the right being regulated by a bye-pass valve 134. Condensers 145, 146 prevent sparking at the switches. An arm 52 integral with the arm 27 carries, at its outer end, a spring-pressed friction pad 55 which bears on the face of the inertia member 17 and thus prevents undesired surges of this member. The axle bar is supplied with oil through a passage 48; and a packing 49 minimises the leakage of oil from the axle box. Such oil as escapes is thrown into the channel 50, is discharged through the opening 51 in the member 17 and collects at the bottom of the casing.

IPC: C07C67/36
Filed: 1925-04-22
Abstract: 252,848. Johnson, J. Y., (Badische Anilin & Soda Fabrik). April 22, 1925, Alkyl formates are produced by the action of carbon monoxide on an alcohol at an elevated pressure in the presence of a metal alcoholate and at a temperature of 30-140‹ C., preferably 60- 100‹ C. The carbon monoxide is forced, either continuously or at intervals. into a heated autoclave containing the dehydrated alcohol in which a small amount of sodium or potassium has been dissolved. The gas is preferably introduced below the liquid level in order to assist the stirring. When the reaction is complete, the product is either withdrawn by a reduction valve at the bottom of the autoclave and separately distilled or is distilled off through a valve at the top; the main portion of the alkali alcoholate remains behind in the solid state. The apparatus is preferably protected against the carbon monoxide, either by using a special steel, e.g. steel V2A, or by lining it with a metal such as silver or brass; whilst the carbon monoxide is purified from iron carbonyl, sulphur compounds, and moisture. Pressures of from 60 to 1000 atmospheres are mentioned in the examples. which describe the preparation of methyl, ethyl, and butyl formates from the corresponding alcohols.

Title: Initiation and maintenance of power-welding arcs
IPC: H01J9/12
Filed: 1960-03-25
Abstract: 930,211. Arc - torches. AIR REDUCTION CO. Inc. March 25, 1960 [April 27, 1959], No. 10744/60. Class 39 (3). [Also in Group XXII] A thermionic arcing electrode in a welding torch is pre-heated by internal resistance heating to facilitate striking the arc. The electrode may be consumable or non-consumable. In one arrangement, Fig. 1, a tungsten electrode 1 is supported in a gas nozzle 2 to which a shielding gas such as argon, helium, hydrogen, nitrogen or mixtures thereof is supplied through a conduit 3. The electrode 1 is divided lengthwise into two parts separated by insulating material 4 except at the arc-supporting terminal portion where the parts are conductively joined together. The material 4 may be a thin film of aluminium oxide or a silicate and may contain a material for bonding the electrode parts together, a flux for facilitating the fused union between the electrode parts or an electron-emitting material. Heating current is supplied by a transformer 5 and may be made adjustable. A source 11 of welding current and a source 14 of sparking voltage are connected between the mid-point 17 of the secondary winding of transformer 5 and a workpiece 10 via the contacts 15 of a contactor 16. In an alternative arrangement, Fig. 2, one part of the divided electrode 20 is connected to one welding circuit conductor 19 and the other part is connected through a switch 21 and an adjustable resistor 22 to the other welding circuit conductor 23 which is connected to the workpiece 24. In one position of the switch 21 welding current passes through both parts of the electrode 20 in parallel. In the switch position shown the welding current is confined to one part of the electrode. In the other switch position a heating circuit is completed through both parts of the electrode in series and resistor 22. Suitable holders for supporting and supplying heating and welding current to the divided electrode are described (Figs. 4 and 5, not shown). If the parts of the divided electrode are very small they may be mounted in an adaptor extension of the electrode holder (Figs. 6-8, not shown). Fig. 9 shows an arrangement employing a solid electrode 75 in place of a divided electrode. Heating current is supplied to the part of the electrode between a collet clamp 78 and a pair of jaws 76 attached to the body portion 77 which is insulated from the clamp 78 by members 781 and 79.
