Title: Improvements in and relating to apparatus for the production of wire clamps or clip closures around the necks of packages
Inventor: HILLMAN ARTHUR JOSEPH
IPC: B65B51/04
Filed: 1960-10-31
Abstract: 1,008,325. Packaging machines. SPICERS Ltd. Sept. 29, 1961 [Oct. 31, 1960], No. 37381/ 60. Heading B8C. [Also in Division B3] A machine for closing the ends of tubular packages comprises means for feeding two wires in spaced relationship to a station where a length is cut from each wire and bent to U-form round an anvil, the anvils then being withdrawn in directions normal to the planes of bending and the clips so formed placed round a contracted neck portion of a tubular wrapper and clenched and the neck cut between the clips. A pair of wires 30 from rolls 29 each pass through an oiling pad 35, a fixed guide 36, to a feed member 37 which reciprocates about a pivot 38 and which advances the wire by means of a pawl 41, each wire passes through a further non-return pawl and stud 44, 43 and into a slot 51 in a fixed cutter die. The lower of each of two pairs of folding blades 53 advance horizontally and sever portions from each of the wires, and bending them to U-form round a pair of anvil pins 66. The blades 53 are mounted on a slide 54 which is reciprocated by a follower 61 running in a cam slot 63. Similarly reciprocated members 69 force a pair of arms 67 apart to withdraw the pins 66 and blades 56 forward the partly formed clips towards a recess 73 in a pair of jaws 24, 25. The wrapping material may be a net tube fed from a mandrel 111 down which the contents 113 to be packed are fed. A portion 116 of the tube is contracted, e.g. by twisting, and pushed between the jaws 24, 25. This causes the upper jaw to rise and to operate a micro-switch 23. A slide bar 77 biased to the right of Fig. 1 by means of a spring 74 forces, by way of its pivotal connection to a toggle linkage 26, 27, the upper jaw downwardly. The lower jaw 25 is forced upwardly to clamp the neck by means of a wedge roll 81 on a lever 82 pivoted at 93 by a cam-operated slide bar 96. The upper end of the lever 82 carries dies 91 which have recesses on one face engaging the ends of the clips and folding them over as they are fed forwardly by the feed members 56. A cutter blade 100 is vertically reciprocated by means of cam-operated links 101-106. A slide bar 85 has abutments 84, 88 which engage the rear end of the slide 54 and a stop 76 of the slide bar 77 as the slide 54 is returned to open the jaws 24, 25 when the clips have been applied and the neck cut.

Filed: 1971-08-10
Abstract: 1315777 Automatic control of magnetic field SPECTROSPIN A G 10 Aug 1971 [13 Oct 1970] 37428/71 Headings G3R and G3X The magnetic field produced by a coil is stabilized by connecting a negative resistance device across the coil so that current induced in the coil by a disturbance of the field produces a field substantially equal and opposite to the dis-  turbance. In the embodiment of Fig. 7, a coil 1 with internal resistance R 1  is connected in series with an operational amplifier 5 provided with positive feedback by resistors R 4 , R 5 , R 6 . The magnitude of the variable resistor R 6  is adjusted so that the equivalent negative resistance of the amplifier equals the resistance R 1 . The magnitude of the field in coil 1 is determined by a current supply 3. In another embodiment, Fig. 8 (not shown), two amplifiers each with one input grounded are connected across the coil. A further embodiment, Fig. 9 (not shown), uses a nuclear magnetic resonance device to detect changes in the field and provide correction signals in addition to the stabilizing action of a negative resistance device. The arrangement may be used in a nuclear magnetic resonance spectrometer.

Abstract: 1421270 Integrated circuit INTERNATIONAL BUSINESS MACHINES CORP 8 Aug 1973 [18 Oct 1972] 37571/73 Heading H1K In the manufacture of planar integrated circuits in which upper contacts 51 are formed through holes 52 in an upper insulating layer 53 to a metallization pattern 50 situated on a lower insulating layer 55, at least the majority of the holes 52 are located above areas of the semi-conductor substrate 58 where the conductivity value and type is such as would form a Schottky barrier with the material of upper contact 51. This ensures that, in the event of inadvertent etching through of the lower insulation 55 during formation of the hole 52, e.g. as illustrated, the upper contact 51 remains isolated from the substrate 58 by the Schottky barrier 56, whch can be arranged to be reverse biased by appropriate selection of potentials. Ideally all the holes 52 are thus located. The upper contact 51 may, as shown, cover a larger area than the portion of metallization 50 to which it makes contact in order to maintain large area contact in the event of slight misalignment, but this is not essential. The upper contact 51 may serve for external connection or may connect to a second layer of metallization. The two insulating layers 53, 55 may both be of SiO 2 . For N type Si having a maximum impurity concentration of 10<SP>18</SP> cm<SP>-3</SP> suitable barrierforming materials are Al, platinum silicide, Pt, Pd, Cr, Mo and Ni. For P type material of the same impurity level suitable metals are Al, Au, Cu and Ni.

Patent GB-396435-A (GB)
Abstract: 396,435. Combined sound and kinematograph picture films. FERNSCHREIBER AKT.-GES., 14, Behren Strasse, Berlin. Jan. 23, 1932, No. 2153. Convention date, Oct. 31, 1931. [Class 40 (ii).] A kinematograph picture film having a sound record thereon and bearing also a text record whereby printed or like words corresponding to the recorded speech may be projected simultaneously with the pictures, is so produced that the pictures are reduced relatively to the size of pictures on a normal " silent film, and are displaced laterally. By this means, not only is a longitudinal strip provided at the side of the pictures, for the sound track, but there are also transverse strips between successive pictures on which the text is printed. The text record may be printed from a separate band, on to the positive film stock, simultaneously with the printing of the pictures. The combination film may be projected by means of a lens having a focal length shorter than normal, so that the picture on the screen occupies approximately the same area as that usual with " silent " pictures, and the height of the projection field is increased by the amount of the text strip above or below the picture field. The Figure shows at 92 and 93 respectively two arrangements of picture, sound record, and text that may be adopted, 91 being the same picture as it appears on an ordinary silent film. In the arrangement shown at 92, the proportions of the picture are unchanged as compared with the normal picture shown at 91, but the sound record and the text encroach upon the picture space. In the preferred arrangement at 93, the whole of the picture is printed from the picture on a normal negative, but with reduction and appropriate lateral displacement, and without changing the distance between centres of successive pictures.
