Abstract: 851,458. Nuclear reactors. WHESSOE Ltd. March 31, 1959 [Dec. 31, 1957], No. 40448/57. Class 39(4). The interior surface of a nuclear reactor pressure vessel is protected by a heat insulating covering formed of sheets of stainless steel, corrugated to contain pockets of gas. The covering is secured by bolts welded to the shell inner surface. As shown, the inner surface of the pressure vessel 10 is covered by the metal sheets 11, 12 which are spaced by the corrugations in 11.

Title: Method of and apparatus for controlling depth of fusion in  electron- beam welding
IPC: B23K15/02
Filed: 1974-09-18
Abstract: 1453526 Welding by fusion INST ELEKTRO IM EO PATONA AKAD NAUK UKRAIN SSR 18 Sept 1974 40648/74 Heading B3R [Also in Divisions G1 and G3] The depth of fusion in electron beam welding is controlled by deriving a signal proportional to the scattering of beam electrons due to interaction with metal vapour produced by welding, filtering the signal to obtain a component with a frequency of over 200 c/s, and using the component to control the welding heat input. The method is used in a welding apparatus comprising an electron gun 1 producing a beam 7 which is automatically focused by a coil 6 and unit 8 to give a constant size hot spot on the workpiece 9. The gun comprises a cathode 3, control grid 4 and anode 5, and the whole apparatus is in a vacuum chamber 2. A beam trap 11 collects scattered electrons and produces a signal across resistor 12. A filter 13 blocks the passage of D.C. and frequencies below 200 c/s, and the signal is then amplified, rectified and smoothed before feeding to an indicator or recorder Q and a comparator 17. The latter also receives a reference signal from a source 18 which is adjustable or may vary to give a changing weld depth. The output of the comparator is amplified and fed to the grid 4 to reduce the welding power input if the scatter current is increasing, and vice versa. The recorder Q may be a chart recorder driven at the speed of the workpiece relative to the beam so that a defective weld portion may be quickly located by laying the chart over the weld. It is stated that weld quality is improved if the beam is periodically removed from the workpiece at the frequency of the selected component of the scatter current signal. This may be achieved by use of a further signal fed to an additional beam deflection coil (24, Fig. 5, not shown) or to the grid 4. The further signal is produced by a generator (21) and comprises pulses of a duration determined by the output of the comparator 17 and synchronized with the leading edges of the half waves produced by amplifier 14.

Title: Self locking differential mechanism
Filed: 1960-11-28
Abstract: 895,819. Differential gear. HILADO, A. Nov. 28, 1960, No. 40766/60. Class 80 (2). A differential for motor cars which is selflocking when one of the driven road-wheels tends to spin comprises sun gears 1, 2 splined upon the usual half-shafts and meshed by pairs of planet pinions 4, 5; 8A, 9A integral with worms 6, 7 ; 8, 9 meshed together in pairs. The worms 6, 8 are of larger size than the worms 7, 9, which they mesh, and all the worms are formed with Acme threads. The worms of each pair are of opposite hand, their radially tapered threads permitting their intermeshing. The arrangement is such that on relative rotation between the half-shafts, the larger worm 6 or 8 of each pair can drive the smaller worm 7 or 9, but not vice versa. Accordingly spin of the individual road wheels is prevented while normal differential action, e.g. when the car rounds a bend, is permitted.

Abstract: 889,288. Cigarette-making machines. MOLINS MACHINE CO. Ltd. Nov. 30, 1960 [Dec. 1, 1959], No. 40785/69. Class 130. Cigarettes or stub lengths fed lengthwise into the flutes of a drum 6, Fig. 1, and arrested a short distance from stops 8, 9, are moved against the stops by air pressure or suction. In Fig. 1 cigarettes from a cut-off are moved sideways by a helically grooved suction wheel 3 into the flutes 6 of which alternate ones have stops 8 at their mid-point and stops 9 at their far ends, whereby the cigarettes form two rows for delivery to a catcher band 7. The cigarettes are braked by spring devices as described in Specification 875,330 so as to be arrested a short distance from the stops 8, 9. A shroud 28 surrounds the flutes and air under pressure supplied through a nozzle 40 urges the cigarettes against the stops. A subsidiary nozzle 41, Fig. 3, may be provided in the flutes containing the stops 9. Alternatively the lengths may be moved by suction applied at the left-hand end of the flutes. The plate 2 over which the cigarettes are fed to the wheel 3 is perforated at 60 and connected to a suction device to remove tobacco dust. In Fig. 4 multi-length stubs S are fed to a fluted wheel 50 and urged against stop 52 by air pressure from a nozzle 54 in a shroud 53. The stub lengths comprise lengths of filter material with gaps 55 therebetween and are subsequently cut at 56 to provide double-length mouthpieces for attachment to a pair of cigarettes and bi-section at the gaps 55 to give hollowended mouthpiece cigarettes.

Title: Improvements in or relating to a method of and apparatus for producing a cheese package
Inventor: PALMER HERBERT JOHN
IPC: B65B25/08
Filed: 1958-12-18
Abstract: 899,176. Packaging. SWIFT & CO. Ltd. March 18, 1960 [Dec. 18, 1958], No. 40847/58. Class 94(1). Interconnected packages 7, (Fig. 1), containing cheese are produced by extruding the cheese between two superimposed strips of heatsealable wrapping material, sealing the edges of the strips to form a cheese-filled tubular package, and then applying heat and pressure along spaced transverse areas 40 to displace the cheese away from those areas and press the tube forming strips together to separate the cheese into individually wrapped portions. In Fig. 3, the strips 14, 15 surround an extrusion nozzle 19 fed from a hopper 21 containing heated processed cheese. The side edges of the foil are partly turned over by inclined guide members 24 before passing beneath rollers 22, 23, effecting the final folding, the tube being then heat sealed along both edges. A gripper 26, driven by a rock and pinion 27, 28, draws the requisite length of filled tubing on to a table 9 and a knife 29 then descends to seal the end of the tube and sever it from the supply. After the gripper 26 has released its hold an arm 30 reciprocates to move the package beneath a first section 33 of a press 31. The press 31 descends, (Fig. 6), to shape the filled tube into a rectangular package 37 and to further heat-seal the ends by heated press elements 38, (Fig. 3). The next package to be pressed displaces the rectangular package 37 to a position beneath a second section 34, of the press, formed with transverse projections 39 that are used to form the transverse sections 40. The resulting package is finally moved beneath a third section 35 of the press that has projections 43 for perforating the transverse sections 40. The completed packages are removed and allowed to cool on a conveyer 44 and to then drop on to a transverse conveyer 46, (Fig. 5), from which they are delivered to a third conveyer belt 48 such that the cheese package is folded over upon itself along the sections 40 to form a rectangular pack 49. The strips constituting the tube may be so dimensional and positioned that an upper strip 3, (Fig. 2), extends from one edge of the cheese portion 2 to beyond the other edge as at 6, whilst a lower strip 4 is of such width that it overlaps both edges, being folded around one edge and sealed thereto as at 5 whilst its other edge is joined to the projection 6. The projection 6 is then folded down on to the pack to form a tag that can be subsequently lifted and torn along the length of the fold. Modifications. The two sections 34, 35 of the press 31 can be combined into one section. The transverse projections 39 nay be used to heat seal the sections 40. The projections 43 can be replaced by creasing members. The press 31 may be stationary and the table 9 reciprocate towards it. The package may be cut along the section 40.
