Title: Method and apparatus for making cross-bottomed bags
IPC: B31B160/20
Filed: 1963-10-29
Abstract: 1,030,007. Plastics bags; endless conveyers. GARTEMANN and HOLLMAN G.m.b.H. Oct. 29, 1963 [Nov. 13, 1962], No. 42645/63. Headings B8A and B8K. [Also in Division B5] Bags.-A cross-bottom plastics bag is formed by folding the end of a bag tube to the shape shown in Fig. 4, making welds 23a to hold the triangular portions in position, and applying heated bars which form grooves 23 and lightly weld the bag bottom. The bag bottom is heated and irradiated with electrons; the glue is applied hot, but may be allowed to cool before the bottom flaps are folded along the grooves 23. A valve may be inserted in the bag bottom before this final folding.

Title: Improvements in the preparation of sintered uranium dioxide grains
IPC: G21C3/62
Filed: 1969-08-27
Abstract: 1,256,283. Uranium dioxide. GENERAL ELECTRIC CO. 27 Aug., 1969 [29 Oct., 1968], No. 42696/69. Heading C1A. Substantially spherical uranium dioxide nuclear fuel grains are made by sintering pressed compacts of uranium dioxde or ammonium diuranate in dry hydrogen at a temperature of at least 1900‹ C. until grains of the desired size are formed, and cooling the compacts in hydrogen or inert gas such that metallic uranium is precipitated at the grain boundaries, and when the temperature has reached about 400‹ C. continuing the cooling in a hydrogen atmosphere such that the precipitated uranium reacts with the hydrogen during cooling to form uranium hydride, causing the compacts to disintegrate into the grains that have been formed. The dry hydrogen used in the sintering is sufficiently dry to reduce the uranium dioxide to substoichiometric form, i.e. UO 2-x  where x is up to 0À3. Uranium, or a grain growth accelerator e.g. an oxide of aluminium, beryllium, magnesium or titanium may be added to powdered uranium dioxide or ammonium diuranate before pressing into compacts. A cooling rate of 100- 300‹ C./min. is desirable. When the disintegrated compacts are exposed to air, the uranium hydride is oxidized to uranium dioxide of o/u ratio substantially 2À00. Examples describe the heating of uranium dioxide and ammonium diuranate in molybdenum tubes in an atmosphere of hydrogen having a dew point of-40‹ C., the sintering temperature being 2000-2100‹ C. and the rate of cooling 100-300‹ C./min.

Title: Step By Step Feeding Device for a Punched Support of a Punching or Reading Apparatus.
IPC: G06K13/30
Filed: 1967-09-15
Abstract: 1,174,317. Telegraphy. ING. C. OLIVETTI & C. S.p.A. 15 Sept., 1967 [20 Sept., 19661, No. 42701/67. Heading H4P. A step-by-step reversible feeding device for a teleprinter tape punch or perforator has the perforating or reading pins and feeding pins 76 mounted on a frame 44 which is moved in a closed path by a pair of eccentrics 89, 92 which control the vertical movement of the pins and one of which causes the pins to be reciprocated parallel to the feed direction. When start key 26 is pressed, lever 18 moves clockwise and is latched by lever 32. Lever 18 causes shaft 17 to rotate and allows toothed lever 8 to engage notch 11 so that shaft 5 rotates, rotating eccentric 89, 92 oppositely. With arms 97, 102 in the position shown, eccentric 89, via link 86, moves pivot 83 (and hence frame 44 and pins 76) parallel to the tape whereas the eccentrics together, via links 86, 87, cause pivots 83, 84 to reciprocate vertically. The pins then move in the path ABCDEFGA, Fig. 3. To stop the feeding stop key 38 is pressed, releasing latch 32 which allows lever 38 to re-engage lever 8 to prevent further rotation of shaft 5 by shaft 17. To reverse the feed, the position of arms 97, 103 must be reversed. Pressing key 144 operates lever 18, so causing rotating of shaft 5 again, and also moves T-lever 134 which, via bail 128, allows toothed lever 119 to engage notch 121 so that disc 113 is rotated by shaft 66. The disc makes one revolution, whereafter bail 128 withdraws lever 119 from notch 121. Pins 110 on disc 113 rotate Geneva wheel 108 through 90 degrees, so reversing arms 97, 103. Consequently, as shaft 5 rotates, the feed pins 76 move along the path AB<SP>1</SP>C<SP>1</SP>E<SP>1</SP>G<SP>1</SP>A, Fig. 3. Operation of key 140 causes arms 97, 103 to revert to the positions shown by a similar sequence of operations. The perforating pins (46) are set up by, or the reading pins (46) set, code bars (72) in conventional manner, Fig. 2 (not shown). The tape is clamped during most of the vertical displacement of the pins.

Abstract: 1,200,410. Electro-deposition of metal matrix containing dispersed particles. NSU MOTORENWERKE A.G. and WANKEL G.m.b.H. Sept.9, 1968 [Sept. 9, 1967; Dec.16, 1967], No.42753/68. Heading C7B. A process for the electro-deposition of a metal matrix containing dispersed particles on the surface of a workpiece comprises depositing a layer of zinc on the surface and, using an electrolytic nickel bath containing solid particles, first depositing a thin layer on to the zinc coating with the bath still so that the particles therein are settled out, and then depositing a further layer which consists of a nickel matrix containing dispersed hard particles, the particles being maintained in suspension in the bath during this stage by agitation of the bath. The particles may be of silicon carbide, silicon dioxide, aluminium oxide, tungsten carbide or boron carbide. For deposition of the above described coating upon the inner surfaces of epitrochoidal engine housings, a plurality of housings 13 separated by spacers 16 are secured rigidly by bolts 18 to frame 12 which is positioned within tank 11, containing the electro-plating bath pivotally supported from bridging member 19. Agitation of the bath is provided by passage of compressed air into the bath via pipe 22, and the bath may be circulated via pipes 24, 27 by means of pump 23 to provide further agitation and for regeneration at 26. The anode 21 comprises a basket e.g. of titanium containing pieces of nickel. The basket is shaped to conform to the inner shape of the workpieces 13 and may have the shape of two intersecting cylindrical sections Fig.4, (not shown). The nickel pieces within the basket may be contained within a bag of fine mesh weave to retain small pieces of nickel and impurity. Two conductors extend upwards from the bottom of the anode basket and parallel thereto positioned so as to produce a uniform electric field. If the workpieces are attached to frame 12 without using spacers 16 so that their inner surfaces form a tube, the pipe 27 is located so that the bath may be circulated between the anode and workpiece during operation of the bath. The nickel plating bath may contain nickel sulphamate, nickel chloride, boric acid and saccharine.

Co-ordinate wiring is carried out by passing a wire secured to a hypodermic tube through the slots. Two matrix planes may be wired simultaneously with interconnecting circuits by using the supporting frame 20 shown in Fig. 5, the jigs after wiring is completed being withdrawn through the gap between end pieces 24 and 25, so leaving the wired frame supporting two planes of cores. After the cores are fitted into the jig recesses, they may be retained in place by transparent covers to permit inversion of the supporting frame during wiring. A number of frames may be wired together in a stack by the use of the apparatus shown in Fig. 6. The two jigs in each frame are held in place by a respective pallet 32, and the stack of frames is secured together with interleaved transparent covers 30 by studs 31. The pallets 32 form part of an assembly 33 which is rotatably mounted on a mechanism 34 provided with a spring detent for locking in either of two positions. Wiring is then facilitated by rotating the stack as necessary. When assembly is completed, the stack of frames is withdrawn from the pallets and the jigs removed as previously described. A method of filling the jig recesses with cores is described, Fig. 9, in which a plate 42 is laid over the jig with slots 43 in alignment with the jig recesses. The arrangement is then positioned in the mouth of a funnel 40 the spout 41 of which connects with suction apparatus. The cores are placed on to the plate and enter the recesses by the combined effects of suction, agitation and brushing.
