Title: Improved method of joining sheet members
IPC: B21D39/03
Filed: 1961-07-25
Abstract: 910,157. Sheet-metal joints. REYNOLDS METALS CO. July 25, 1961 [July 28, 1960], No. 26901/61. Class 83 (4). A method of joining sheet-metal members comprises the steps of displacing superimposed portions of the members to form a hollow protuberance, simultaneously shearing the opposed marginal edges of the protuberance so that opposite sides of said protuberance extend angularly toward the plane of the sheet members and terminate in the sheared edges and flattening said protuberance whereby said edges are caused to expand outwardly to overlap the adjacent portions of the sheet members. In an embodiment, the superimposed portions of a pair of aluminium sheets 10 and 12 are placed between a row of opposed interdigitating punches 14 and 16 which form a row of alternate upwardly and downwardly directed hollow protuberances 20 and 22, Fig. 3, each protuberance being separated by a longitudinal shear line 24. Each protuberance has a central arch 26 extending laterally of the sheets and semi-circular side panels 28 integral with the sheet members. The sloping sides of the arches 26 terminate in sheared marginal edges 30 which extend above the adjacent surface of the sheet member. To complete the joint the protuberances are flattened in two stages using a pair of finger dies 32 and 34, Fig. 5. The dies are arranged so that the fingers 36 of die 34 lie beneath the planar surface of die 32 while the planar surface of die 34 lies beneath the fingers of die 32. The die fingers are used to consecutively flatten first the top row of protuberances and then the bottom row of protuberances to form a joint as shown in Fig. 9 wherein the sheared edges 30 are expanded outwardly to form arcuate end flanges 124 extending beyond the adjacent shear lines to overlap adjacent fastening elements 120. The flattening operation imparts a slight corrugation to the fastening elements which stiffens the joint.

Title: Improvements in or relating to gas-turbine power-plant installations
IPC: F02C7/047
Filed: 1947-10-07
Abstract: 638,103. Gas turbine plant. RUBBRA, A. A. Oct: 7, 1947, No. 26971. [Class 110(iii)] In a gas turbine power plant installation having a multi-stage turbine, hot gas is abstracted from between a pair of adjacent stages of the turbine for use in the prevention of ice formation or removal of ice from the compressor intake or parts of the compressor. The turbine plant shown comprises a turbine 14 driving a compressor 12 and an airscrew 17 through a reduction gear 16. The engine air intake 20 is formed between an outer wall 22 forming part of the cowling 11 and a fairing 21 supported from the outer wall by struts 23. The leading edge of the cowling 11 and the leading edge of the fairing 21 have annular chambers 25, 28 formed in them which chambers are connected together by ducts 26, 27 and 19. Outlets 25a, 27a and 28a are provided to convey hot gases from the chambers 25, 28 and duct 27 into the air intake 20. These hot gases are supplied from the engine at a point between the high pressure stage 14a an the low pressure stage 14b through conduits 29 and are regulated by valve means 30 which may be manually controlled or automatically controlled by an ice detector or temperature responsive device. An annular collector chamber 37 surrounding the fixed nozzle guide vanes 31 is connected by passages to the turbine annulus. These passages may be formed by drilling the blade platforms or by cutting away a part of the abutting edges of these platforms. If desired, the annular collector chamber 37 may be replaced by a number of ducts leading to the air intake. When applied to a turbine plant of more than two stages, the hot gas is abstracted from between a pair of adjacent stages where the pressure is only sufficient to overcome losses in the distribution system. The stages may also be mounted on separate shafts. Any means may be used to distribute the hot gases in the intake and the methods described in Specifications 636,612, 638,079 and 638,093, [Group XXXIII], are referred to. Specification 578,769 also is referred to.

Title: Electrical system for monitoring sequentially operating machines
IPC: B21H3/04
Filed: 1957-08-27
Abstract: 843,141. Recording-apparatus. SHEFFIELD CORPORATION. Aug. 27, 1957 [Sept. 4, 1956], No. 26973/57. Class 106 (4). [Also in Group XXII] A system for monitoring a machine having an automatic sequential operating cycle with a controlling system providing electric signals for the actuation of components of the machine, comprises leads 175 to 181 connected to the controlling system for energization in accordance with the electric signals provided and a multiple plug and socket 188 for connecting the leads to a recorder for recording the timed relationship of the actuation of the machine components. A machine for rolling threads on a workpiece comprises opposed threading heads 11, 12 moved to and from engagement with a rotating workpiece by hydraulically operated pistons 25, 36 under the control of valves 121, 156 operated by solenoids 125, 155. To initiate a cycle, switches 100, 107 in a control circuit 80, Fig. 5, are depressed to start motor 110 rotating the workpiece and motor 104 driving a pump 47, while a relay 114 operates a valve 115 to supply lines 50, 51 and solenoid 125 operates valve 121 to allow fluid from the line 50 to drive the piston 25 to the right. As it starts moving, the slide 23 carrying the head 11 actuates a rear limit switch 130, then later actuates a switch 145 while it simultaneously closes a valve 141 to slow down the rate of travel of the slide 23 and finally actuates a forward limit switch 147 to start a timer 150 which, after a predetermined time, de-energizes the solenoid 125 to change over the valve 121 to cause fluid to push the piston 25 back, whilst actuating the switches 147, 145 and 130 in succession. Solenoid 155 then operates valve 156 and the head 12 is similarly advanced and retracted, actuating switches 131a, 131b; 165; and 170a, 170b as it moves in each direction. In the circuit 80, the solenoids 125, 155 and timer 150 are arranged on the side of the common line 182 with respect to their actuating contacts 111b, 130, 147, 151b, 131b and 170a and monitoring leads 175 to 179 are arranged in series with the actuating contacts and in parallel with the solenoids 125, 155 and timer 150, so that the machine operations controlled thereby are performed irrespective of whether the monitoring leads are connected to a recorder or not. Additional monitoring leads 180, 181 have the switches 145, 165 in series therewith. Thus if each lead 175 to 181 is associated with a different stylus, records can be made on a common clock-driven strip between the opening and closing of the following pairs of contacts 111b, 151b; 111b, 131b; 147, 147 and 170a, 111b; 130, 111b; 111b, 130; 145, 145; 165, 165; to give the records shown in Fig. 9. Deductions can be made from these records of the time delay due to each valve 121, 156 and to the timer 150 and of the periods of slow advance of the heads 11, 12, thus enabling comparisons to be made of the timing before and after adjustment of the various valves and the timer.

Title: Improvements in and relating to variable pitch propellers
IPC: B64C11/32
Filed: 1934-09-19
Abstract: 430,557. Screw propellers. LAFOND, G., 56, Rue Notre Dame de Lorette, Paris. Sept. 19, 1934, No. 26974. Convention date, Sept. 19, 1933. [Class 114] Variable-pitch screw propellers provided with mechanism for altering the pitch and with an independent locking device have two connecting members between the non-rotating part of the adjustment means and the part rotated with the propeller and these are engaged only when the pitch is being altered, but disengaged during normal operation. The blade roots carry pinions 4, 4<1> engaged by racks 5, 51 which are locked by means of segments 7, 7<1> which co-operate with members 9, 91. Normally, a spring-urged block 10 holds the parts 9, 91 and so locks the racks with the members 7. When it is desired to move the racks to change pitch the block 10 is slidden endwise, the members 9, 9<1> move outwardly under centrifugal force to release the racks. In an alternative form the racks are carried by bars 15 pivoted at 16, these bars being connected by links 17 on a member 19<1> capable of being slidden by a cam arm 20. Normally, the rack member is in engagement with the locking member 7. When it is desired to move the rack by means of the member 13, the handle 21 is turned and the links 17 tilt the rack bar free from the locking member. Instead of the blade roots having interengaging pinions those members may be made segmental so that the part engaging the racks has a different pitch radius from the interengaging parts. Where more than two blades are employed they are intercoupled with each other by gearing and each is provided with an adjustment mechanism.
