Title: Improvements in or relating to lathes
IPC: B23B19/00
Filed: 1952-09-19
Abstract: 721,637. Lathes. HARBECK, M., STEFFEN, H. W., HARBECK, M., and STEFFEN, E., [trading as HEIDENREICH & HARBECK]. Sept. 19, 1952 [Oct. 27, 1951], No. 23606/52. Class 83 (3). A lathe comprises a bridge-piece supported by two side columns, the downwardly directed part of the bridge carrying a tailstock and provided with a longitudinal guide running parallel to the spindle axis and serving to suspend and guide a carriage supporting the cutting tool above the work, the bridge-piece also supporting a spindle casing for the spindle on its underside. The lathe frame comprises a bed plate 1, Fig. 2, uprights 3, 4 and a bridgepiece 2. The underside of the bridge-piece slopes backwardly at about 30 degrees to the horizontal plane and carries longitudinal guideways 12, 13, Fig. 1, for a suspended saddle 14. A cross-slide 15 on the saddle carries a tool 18 which operates in an inverted position on the work 7. The cuttings are directed downwardly into a clear space below the machine and the turning operation may be observed through a window in front of the machine. A lever tool-rest 19 for transverse cutting and carrying one or more tools 21 may be arranged in the bed 1 and feed of the tools is effected hydraulically. The weight of the saddle is balanced by springs arranged against the guideways. The lathe may be adapted for copying operations in which case a pattern 23, Fig. 1, is supported on adjustable supports 22 provided on the-bridge-piece 2, a feeler 24 carried by the saddle sliding along the pattern and copying its form by means not described. Headstocks; tailstock.-The headstock 28, Fig. 3, is suspended in a U-recess in the upright 3 and is secured to a U-bracket 60 which embraces the saddle and is in turn secured to the bridge-piece. This enables the saddle to be moved past the headstock. A pair of guideways 54 is located with a small clearance below the headstock casing and, to facilitate removal, the headstock when unbolted is lowered on to these guideways and can be slid out of the frame. The tailstock is slidable on the carriage guideways and is similarly located in the withdrawn position in a U-recess of the upright 4.

Abstract: 962,152. Differential gear. DE HAVILLAND ENGINE CO. Ltd. July 8, 1960 [July 9, 1959], No. 23679/59. Heading F2D. A transmission device for driving two contra-rotating rotors 24 from a turbine 11 comprises a sun pinion 13 driven by a shaft 12 coupled to the turbine, the pinion 13 being geared to an annulus gear 14 through a series of planet gears 18. The gear 14 is connected through splines 15 to a sleeve 16 carrying a gear 17, the planet carrier 19 being connected to a sleeve 21 rotatable within the sleeve 16 and carrying a gear 22. The gears 17, 22 mesh respectively with gears 28, 29 fixed to concentric hollow shafts 27, 26 each supporting a propeller 24. The turbine exhaust from a pipe 30 passes through the shaft 27. In a modified device, Fig. 2, the gears 17, 22 are positioned on opposite sides of the epicyclic gear 13, 14, 18 and the shafts 26, 27 function as lay shafts driving through pinions propeller shafts coaxial with the shaft 12. In a further modification (Fig. 3, not shown) the shafts 26, 27 are parallel to each other but are not coaxial. To ensure a positive direction of rotation on starting the torques on the sleeves 16, 21 are different and accordingly to ensure that the output torques at the shafts 26, 27 are equal the gears 17, 22 and 28, 29 are of different ratios. According to another modified device (not shown) the annulus gear is omitted and the epicyclic gear comprises two run pinions meshing with two planet pinions rigid with one another and of slightly different size, the planet carrier and one of the sun pinions being connected to the shafts 26, 27 through the gears 17, 22 and 28, 29 while the remaining sun gear is connected to the shaft 12.

Title: Method and apparatus for the continuous production of packages containing solid and/or liquid material
IPC: B65B9/20
Filed: 1957-07-26
Abstract: 827,792. Packaging-machines. CELLOPHANE INVESTMENT CO. Ltd. July 26, 1957 [July 26, 1956], No. 23773/57. Class 94(1). A machine of the kind which folds a web to tubular form about a mandrel, passes material to be packaged through the mandrel into the tube and flattens and seals the tube at intervals to form packages, initially creases the web to assist folding and produces rectangular section filled bags with end closures of the kind usually associated with bellow side folds. A web 2 is fed towards a mandrel 8 by creasihg rolls 4, 5 which produce the pattern shown in Fig. V, the dotted lines indicating creases on the opposite side to those shown by full lines. The web is tubed about the mandrel 8 and the longitudinal seam heat sealed by a wheel 9. Plates 12, 13 cooperate with fluted mandrel sides to produce partial bellows folds, and a gumming device 14 places gum spots 15, 16 at positions where the tube is to be transversely sealed. These spots permit sealing in the case of paper or like tubes with only inner heat sealing linings. The tube passes between driven rollers 17, 18 and rollers, Fig. 11, (not shown), mounted on the mandrel which pull the tube along the mandrel. Alternatively porous belts 23, 24, Fig. VI, passing across suction heads 27, 28 may grip and pull the tube. Liquid or pasty material is fed by a pump 36 through a pipe 37 to the tube. Granular material may be fed in weighed quantities by means not specified. Heated blocks 42, 43 on belts 40, 41 seal the tube at intervals, and knives, Fig. VII (not shown), mounted in the blocks 42 are operated by a cam 60 to enter grooves in the blocks 43 and separate the packages. The packages drop from the belts 40, 41 and are fed at right angles to their initial direction by belts 70, 71 past gumming means 72 and fixed folding means, Figs. III, IV, (not shown), which apply adhesive to and fold over onto the package bottom their lower seam 69. Packages produced may be flat topped, or peak roofed as shown.

Abstract: 1,173,443. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 25 May, 1967 [1 June, 1966], No. 24471/67. Heading H1K. A lead is connected to a semi-conductor device by positioning a semi-conductor pellet on a substrate, arranging a terminal structure so that a contact member of the structure engages the pellet, securing the terminal structure to the substrate so that the contact member is pressed against the pellet, bonding the contact member to the pellet, and disengaging the terminal structure from the substrate. A plurality of connected supports are formed from a strip of nickel-plated copper so that a plurality of semi-conductor devices can be assembled sequentially or simultaneously. As shown, Figs. 6 and 8, each support 12 is provided with a mounting area 16 surrounded by a dovetailed groove 18. A silicon transistor die 44 having a coating of lead on its lower surface and two bonding pads of lead on its upper surface, is positioned on the mounting area 16 and a nickel " clip " 28 is positioned transversely to the support. The clip 28 comprises two side sections 32 connecting end sections 30 from which extend resilient terminal members 36 having bent down end portions 40 which are pressed against the contact pads on the die 44. The side members 32 have recesses (34) which fit over the support 12 and the clip is secured in position by swaging tabs 20<SP>1</SP> on the support against the side members 32. The assembly is heated to solder the die to the support and the end portions of the terminal members to the contact pads. Encapsulation material is moulded over die 44 and terminal members 36 and enters the dovetail groove 18 which serves to anchor the encapsulation to the support. Each support is then separated from the original strip of supports, the swaged tabs 20<SP>1</SP> are removed to release the clip and each end section 30 is cut to leave a single strip extending from the encapsulation to form leads to the terminal members 36, Fig. 10 (not shown). In a modification the semi-conductor die is insulated from the substrate by a ceramic plate, for example of beryllia, and three terminal members are provided on the clip. In a second embodiment, Figs. 11 to 13 (not shown), a plurality of dice are positioned on connected supports and are contacted by terminal members extending from a strip which is secured to one edge of the support strip by deforming the sides of a slot in each support around tabs depending from the strip. The devices are then soldered and encapsulated and the strip is then subdivided to form leads for each terminal member and for the tabs secured to the substrates.
