Abstract: 1469671 Making bags; seaming ROBERT BOSCH GmbH 17 Oct 1974 [19 Oct 1973] 44988/74 Headings B5D and B5K A method of producing bags from a longitudinally folded thermoplastic plastics foil web comprises advancing the folded web to a first welding station whereat the folded web is transversely welded over only a portion or portions of its width, advancing the thus welded web to a further welding station or stations whereat, after hardening of the first welded portion or portions, the folded web is transversely welded over the remaining portion or portions of its width, and advancing the welded, folded web to a cutting device for severing a bag from a chain of bags joined at transverse weld seams 10, 11. The welding stations may produce single welds or double welds 12 to 17 as shown. Each seam 10, 11 may comprise three or more welded regions produced at two or more welding stations. For example, the web may be welded in its central region at the first welding station and at its marginal regions at a second welding station, or vice-versa. An apparatus, Fig. 2 (not shown), for performing the method may comprise a folding triangle (20) and guide (21) for longitudinally folding the web, spaced pairs of welding jaws (23, 24), pairs of cooling jaws (25, 26) located downstream of the associated welding jaws, and feed rollers (22) located downstream of the welding and cooling jaws and upstream of a web cutting device (29).

In the production of green compacts for sintering by the isostatic compression of particulate materials within a mould 9, comprising a reversible gel e.g. a gelled highly plasticized polyvinyl chloride composition, distortion and/or fracture of the compacted material 12 upon release of compacting fluid pressure and expansion of the mould 9 is avoided by surrounding the mould cavity with a body of particulate material 10 which is readily compactible and which is located within the body of the mould 9 and, after compaction by the fluid pressure, withstands the expansion stresses exerted by the portion of the gel between the compact 10 and the compact 12, and which portion is then removed by the melting thereof e.g. by heating to 170‹ C. or, alternatively, by cutting away if the gel incorporates a release agent. The body of material 10 is in the form of a ring for the illustrated compact 12 of a crucible, and desirably approximates in form to that of the compact 12 which may also comprise a tube, nozzle or capsule.

Abstract: 459,018. Calculating- machines. KOOPERATIVA FORBUNDET FORENING U.P.A. 10, Stadsgarden, Stockholm. May 5, 1936, No. 12689. Convention date, May 6, 1935. [Class 106 (i)] The actuating rack of a calculating - machine or cash register is provided with teeth adjacent which the pivot of a two-armed lever is given a constant reciprocation at each operation, one arm of the lever thus meeting a key-set stop whereby the other arm is turned to engage a rack tooth, the rack then being carried along for the remainder of the stroke of the reciprocation. The actuating racks 1 have teeth 7 normally masked by a bar 14 held in its lower position by a spring 19. The bar 19 is slidably guided on its rack 1 by pins 18 and slots 16. When a numeral key is depressed its stem 29 is moved to the right into the position shown, where it is in the path of a lever 23 carried on a rod 9 reciprocated through a constant distance by a link 13, lever 12 and cam 11 secured to the mainshaft. When the lever 23 meets the set keystem 29 the lever is rocked so that its arm 27 pushes aside the bar 14 and engages with the adjacent tooth 7 of the rack 1. The rack 1 is thus carried upwards for the remainder of the upward movement of the rod 9, and this differential movement is transmitted to the totalizer, &c., by rack teeth 20, 21. The upward movement is limited by a stop and the rack 1 is normally held by another stop 41 which blocks the bar 14 when this is in its normal position. The lever 23, Fig. 6, may be latched, in that position in which it engages the teeth 7,-by a latch 36 released by a fixed stop at the end of the upward travel of the rod 9.

Title: Improvements in or relating to methods producing semiconductor material
IPC: C23C16/48
Filed: 1965-11-05
Abstract: A monocrystalline semi-conductor element is deposited from a reaction gas containing a gaseous compound of the element on to a mono-crystalline semi-conductor carrier body doped to a resistivity not greater than 0.1 ohm cm., and heated to a temperature which is equal to or above that corresponding to the maximum deposition rate (Tm) and lies in the range in which the deposition rate decreases with increasing temperature for the particular reaction gas used. Preferably, Si is deposited on to a Si body from a gas containing SiHCl3, SiCl4, SiH2Cl2 or SiH3Cl.  The body may be heated by passage of electric current, by placing it on a heated support, e.g. graphite, by H.F. induction heating, or by radiation from a source outside the vessel.  The gaseous compound may be mixed with a reactive and/or non-reactive gas, e.g. H2 and Ar respectively.  Tm depends upon the composition of the gas mixture: with 5 mole per cent SiHCl3 and 95 mole per cent H2, Tm is 1400 DEG  C.; with 2+98 mole per cent respectively, Tm is 1100 DEG  C.  In the latter case operating temperatures of 1200 DEG  and 1250 DEG  C. are specified. The gas pressure may be 1 atm., and the flow rate 10 1./min. Selected areas of the body may be raised to a higher temperature, e.g. 1350 DEG  C., by supplementary means, e.g. by optically concentrating light (e.g. wavelength less than 1 m ) from a laser source, in order to reduce the amount of material deposited on, or even to remove material from, those areas. The carrier body may be a disc, rod, or strip; the deposited layer may be of opposite conductivity to the carrier body and may have a sp. res. of 1-100 ohm cm.
