Patent GB-352559-A (GB)
Title: Improvements in or relating to presses for working sheet metal and the like
IPC: B21D24/02
Filed: 1930-04-16
Abstract: 352,559. Cupping. FITZPATRICK, H. D., 94, Hope Street, Glasgow.-(Marquette Tool & Manufacturing Co. ; 1900, North Kilbourn Avenue, Chicago, U.S.A.) April 16, 1930, No. 12007. [Class 83 (iv).] In cupping sheet metal gripped at the edges between dies 13, 14, the buffer 22 which recedes as the punch advances, is yieldingly supported by liquid pressure on a piston 18 supplied from a tank 32, the liquid in which is subject to fluid pressure from a supply pipe 33, while a valve 39 operated by variable fluid pressure from a tank 46a controls the pressure resistance of the buffer. The buffer is also prevented from following immediately the up stroke of the punch. The punch strips itself from the cup before the holding die 13 rises. The valve 39 is held down by fluid pressure from tank 46a acting on two pistons 41a, 41b until the ram has descended when a finger 69 on a rod 49 connected with the press flywheel 25 opens a 2-way valve 44g so that fluid pressure is also supplied below the piston 41b and thereby reducing the total pressure holding down the valve 39. The valve 39 is then raised off its seat by the pressure in the cushioning cylinder 15 so that the liquid therein escapes through valve 39 and along pipe 30 to the tank 32. When the ram ascends a collar 53 on the rod 49 trips an arm 50 which through a lever system 61 opens a valve 38 whereby liquid flows back through valve 38 and valve 37 to raise the piston 18 which is now free of the ram pressure and so eject the cupped blank. Further raising of the ram causes the finger 68 to reset the valve 44g so that the underside of piston 41b is open to atmosphere and the full pressure acts on the tops of piston 41b, 41a to close the valve 39 and hold it down until the next cycle.

Title: Improvements in or relating to wrapping machines
IPC: B65B35/24
Filed: 1939-04-24
Abstract: 527,952. Wrapping-machines. BRONANDER, W. B. April 24, 1939, No. 12299. [Class 94 (i)] The machine wraps articles to form packages of the block-ended type shown in Fig. 18, a portion 87 of the wrapper being arranged to project to form a tab for opening, The articles X, Fig. 3, are fed. from the base of a hopper 33 by cross-rods 36 on endless chains 37, and travel over a table 30 towards the position at which they receive a wrapper. Heat-sealing material is drawn from a roll S by feed rolls 62, 63 and passes downwards between knives 80, 82 and a gap 32 between the tables 30, 31. A length is severed when the article has engaged the forward end of the web, and is carried by the article into the folding mechanism. The knives are shaped so that the end of the wrapper has a projection 87, and are mounted for timing adjustment. The article passes over the table 31 and beneath a wall 100, which fold the wrapper on to the forward end, top and bottom, leaving portions extending laterally and rearwardly. Further travel is effected by members 135, on endless chains 136, having a U-shaped extension 141 which passes between the upper and lower rearward extensions of the wrapper, and engages the rear face of the article. The folds 116 are formed by tuckers 115, Figs. 6 and 7, slots 117, 118 receiving the flaps F<SP>1</SP>, F<SP>2</SP>. These flaps are folded downwards and upwards respectively by slots 123, 126, and adhesion is effected by a heating element 130. All the parts are adjustable to allow articles of different sizes to be wrapped. Brackets 106, 107, Fig. 7, are mounted on spindles 110 having right- and lefthand screw threads 108, 109. The spindles are connected by sprocket and chain connections 111, 112, 113 and can be simultaneously rotated by a crank 114 to adjust the side walls 104, 105 and the package supports 102, 103. The wall 100 and parts 119 are vertically adjustable. Alternative methods of feeding the article through the folding mechanism may comprise endless bands mounted above the wall 100 having pushers projecting through slots, and moving at a speed greater than that of the chain 37. After passing the element 130, the wrapper is now in the form shown in Fig. 16. The end folding takes place on a table C, Figs. 1 and 3, on to which the packet is fed so that the forward end rests against a rail 150. A feed member 191, Fig. 5, pushes the packet towards a folder 163 to form the fold 161 with an accelerating speed which finally becomes the same as that of lugs 151 on feed chains 153. Rotary tuckers 165 turn down the fold 160, and the flaps 140, 145 are turned down by slots 170, 171, to complete the packet.

Title: New arrangement for the production of sustained electrical vibrations specially applicable to wireless telephony and telegraphy
IPC: H04B1/04
Filed: 1920-05-04
Abstract: 153,553. Soc. IndÚpendante de TÚlÚgraphie sans Fil. Nov. 5, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Electric oscillations, producing; thermionic relays and detectors.-In a thermionic generator, variations in the plate potential of one or more generating valves are transmitted to the grids thereof, to sustain the oscillations, through one or more relay valves, which are so coupled to the generating valves by resistances and capacities that variations in potential of the grids of the generating valves are maintained in desired phase relation with the variations in potential of the plates. In the arrangement shown, the grid 8 of a relay valve I is connected to the anodes 16 of two generating valves II through a condenser 10 and inductance 1. The grids of valves I and II are connected to a point of fixed potential through resistances 11, 15, and maintained at a suitable potential by batteries 6, 7. The plate 12 of the valve I is connected through the condenser 14 to the grids 9 of the valves II, and to the high-tension battery 3 through the resistance 13. An increase in anode current in the valves II causes an increase in the potential of grid 8, which results in a decrease in the potential of the anode 12 and a consequent reduction in the potential of the grids 9. The anode current of the valves II is therefore reduced and oscillations sustained in the circuit 1, 2. By regulating the resistances 11, 13, 15 and the capacities 10, 14, any desired phase displacement may be obtained. For this purpose also capacities may be inserted in parallel with the resistances 11, 13, 15 or between the grid and plate of either the relay valve I or the generating valves II. The connexions on the inductance 1 to the grid 8 and the plates 16 may be variable. The arrangement may be used as a wireless receiver by connecting the aerial to the point 19 on the inductance 1 and earthing point 18.
