Title: Method of welding aluminium
IPC: B23K28/00
Filed: 1924-11-27
Abstract: 226,187. Peukert, W. Dec. 12, 1923, [Convention date]. No Patent granted (Sealing fee not paid). Welding.-Aluminium is welded electrolytically by immersing the parts in and connecting them to one pole of an electrolytic bath. The parts to be welded are mounted so as to form the cathode of the bath which may contain water, preferably with additions for increasing its conductivity. The anode has a surface area much larger than the cathode so that a high-current density prevails on the cathode. On passage of the current the ends of the parts to be welded are heated to melting point and are then pressed together to complete the weld. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the welding of aluminium alloys. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 7226/92, 7711/95, and 8134/96.

Title: Means for automatically adjusting brake pressure
IPC: B60T8/17
Filed: 1957-09-10
Abstract: 829,720. Fluid-pressure brakes. GOODYEAR TIRE & RUBBER CO. Sept. 10, 1957 [Dec. 27, 1956], No. 28500/57. Class 103 (1). Apparatus for automatically adjusting brake pressure applied to an aircraft wheel comprises a pilot controlled on-off valve controlling the supply of pressure fluid, a pressure-regulating valve controlled by a reducing gear, skidsensing means, and reversible driving means associated with the reducing gear to adjust the regulating valve to decrease pressure when rapid deceleration occurs and to increase pressure when rapid acceleration occurs. A pressure-regulating valve 12 is normally positioned to pass fluid under pressure from pump 9 to the brake 1, 4, 5, 6, 7 via a pilot-controlled valve 13 and a valve 42b. Should the pressure supplied be too great and the wheel decelerate too quickly a solenoid 42 of an antiskid device 43 of the type described in Specification 764,788, is energized from a generator 2 driven by the landing wheels, a solenoid 42a is also energized to open valve 42b to release some fluid from the brake to allow the wheel to recover speed. The solenoid 42 moves the contact of relay 38 against spring 40 to energize a solenoid 36 whose armature 34 moves to engage a clutch 30, with a bevel gear 26 driven continuously by a D.C. motor 29 through bevel gear 28, a gear 21 on shaft 24 then drives a gear 19 to move a threaded spindle 15 operatively connected to the control valve 12 to reduce the pressure supplied to the brakes, a knob 23 and gear 20 on a shaft 22 permits the valve 12 to be set manually. On recovery of speed, solenoids 42, 42a are de-energized and valve 42b opens to permit normal braking; the movable contact of relay 38 is returned to the position shown by spring 40, a solenoid 37 is then energized and clutch 31 engaged with bevel gear 27 to drive shaft 24 in the reverse direction to open valve 12 to increase the pressure flow; in the full open position the end of spindle 15 engages a switch 41 to disengage clutch 31. In a modification, Fig. 2 not shown, the regulating valve is further operated to control the braking pressure in accordance with aircraft speed, gross weight, lift coefficient and runway friction coefficient, as described in Specification 817,854, in addition to antiskid means similar to that shown in Fig. 1 except that clutches 30, 31 are replaced by magnetic clutches operated by solenoids. A further modification, Fig. 3, not shown, includes a reversible motor to drive the gearing to operate the regulating valve.

Abstract: 862,501. Guillotine cutting - machines. PAPIERVERARBEITUNGS-MASCHINENWERK PERFECTA VEB. Sept. 5,1958, No. 28568/58. Class 31 (1). In a guillotine cutting-machine having an hydraulic arrangement for operating a workclamp 28 in which liquid is moved between a driving cylinder 14 and a driven cylinder 15, the driving piston consists of a thrust piston 17 and a pressure-piston 18, the piston 17 having an area greater than, and the piston 18 having an area smaller than, that of the driven piston 23, and the driving piston is movable by means of a bell-crank lever 3 loaded by an initially tensioned spring 2 and controlled in dependence upon the movements of the blade carrier 7. The cylinder spaces 19, 20 pertaining to the pistons 17, 18 are connected by independently-controlled valves 21, 22 with the space 15a of the piston 23. The valves are arranged in a valve body 13 which has connected thereto an escape container 30 and a pressure switch 31. When, following initial downward movement of the blade carrier, the work clamp is moved downwardly to contact the material 29 to be cut, the valve 21 automatically sets itself so that the connection of the space 19 with the space 15a is interrupted and at the same time a conduit from the space 19 to the container 30 is opened. The material 29 is then further pressed until the pressure set on the switch 31 is reached in the space 15a whereupon the valve 22 shifts over into a position in which the space 15a is also shut off from the space 20. After cutting, the blade carrier returns to its highest position and this causes the parts to be restored to their initial positions.

Abstract: 1,136,393. Roller conveyers. DOUGLASROWNSON Ltd. 1 July, 1966 [7 July, 1965], No. 28831/65. Heading B8A. Articles are propelled along a roller conveyer by rollers mounted on driving members which are pivotally mounted on an endless belt or chain. The conveyer shown comprises two rows of rollers 1 and each driving member comprises a roller 15 rotatable on arms 16 which are pivoted to a bracket 18 on an endless belt 8, 9. Tension springs 20 normally hold the driving member in the position shown but the member may pivot in a clockwise direction. Supports 3 for the rollers 1 are vertically adjustable by bolts 5. If there is a stoppage of an article 30 the arms 16 of the driving member are able to yield in a clockwise direction so that the roller 15 can pass under the article. This roller may have a freewheel arranged to prevent articles over-running when the conveyer is on an inclination. In a modification (Fig. 3, not shown) a ramp (40) depresses each roller (15) which is prevented from engaging the article (30) so that no drive is transmitted over this portion of the conveyer. In Fig. 4 (not shown) a ramp (41) engages the undersides of the rollers (15) which are thus driven and cause any articles accumulated above the ramp to be moved away at twice the speed of the belt. In Fig. 5 (not shown) a pad (45) of frictional material is supported on a link (46) connected to the arms (16) of a driving member. The pad may engage the undersurface of an article to assist in dispersing an accumulation of articles or in preventing over-running when the conveyer is disposed downhill.
