Title: Improvements in machines for forming composite stripping
IPC: A43B13/39
Filed: 1952-04-10
Abstract: 712,360. Folding edges of sheet materials; guillotine cutting machines. HEIDE, H. C. (Prime Manufacturing Co.). July 25, 1952 [April 10, 1952], No. 9300/52. Classes 31 (1) and 42 (1) A machine, adapted to form composite stripping comprising a tape or strip-like covering of fabric, leather &c. folded about and partially enclosing a continuous stiffening core, has cooperating forming rolls and is constructed to permit the core and tape to be progressively brought to and fed through the rolls, the rolls being adapted progressively to fold the tape about the core to form a longitudinal rib thereon. The stripping is adapted to be shaped to a sole blank to act as a sewing rib. As shown, tape material 11, coated on one side with adhesive, and core material 10 are drawn through a channel 20 and a guide 17 respectively and are brought together as they pass between two pairs of forming rolls. The core 10 is gripped between the halves 29, 30 of one of the first pair of forming rolls. Fig. 4, and pressed edgewise against the tape 11 as the latter is supported by the co-operating rolls 25. Recesses 39, 41 in the second pair of forming rolls 38. 40. Fig. 5, act to fold the tape partially around the core, leaving the margins of the tape projecting in opposite directions. The partially-formed composite stripping now passes over an oblique knurled roll 48 whereat the lower tape margin 12 is folded back so that both margins 12 and 13, Fig. 3,have their adhesive. surfaces facing in the same general direction. The stripping is drawn through the apparatus by knurled, driven feed rolls 57, 61. Forming and tucking rolls 71, 73 and 71<1>, 73<1> are provided in advance of, and following, the feed rolls. Roll 71 is pressed by a spring 68, Fig. 7, against roll 73 to press the component parts of the stripping together, and roll 71 is provided with a tucking flange 72 which defines accurately the fold vertex in the folded tape margin. Margin 13 is slashed at 14, Fig. 3, by a rotary bladed cutter 65 co-operating with a slotted anvil 66, or by blades mounted on the rim of the lower' feed roll. The finished stripping passes to a reel upon which it is coiled. Specification 712,381, [Group VII], is referred to.

Title: Process for absorbing isobutylene in strong acids
IPC: C07C29/06
Filed: 1931-03-27
Abstract: In the process of absorbing isobutylene in strong acids, e.g sulphuric, phosphoric, and toluene sulphonic acids, more molecular proportions of isobutylene are absorbed per molecule of acid than correspond to the basicity of the acid.  The acid liquors obtained may be worked up into polymers of isobutylene, mainly di- and tri-isobutylene, by heating, preferably under pressure, with or without previous dilution; or tertiary butyl alcohol may be obtained by distillation.  If the distillation is effected in such a manner as to obtain a quick removal of the vapours, e.g. by distillation with steam or under reduced pressure, or both, it is unnecessary first to neutralize the acid liquor, but it is preferred to have during the distillation an acid concentration of less than 40 per cent when sulphuric acid is employed.  The best yield of the alcohol from the isobutylene absorbed is obtained with not more than 3 molecules of isobutylene per molecule of sulphuric acid.  In examples (1) isobutylene is absorbed in sulphuric acid.  (2) Isobutylene is absorbed in isopropyl sulphuric acid, and the mass is then neutralized with ammonia, and steam distilled.  The alcohols are salted out and dried.  (3) The alcohols are distilled off under reduced pressure.  (4) The process is similar to that of Example 2. (5) The acid liquor is diluted slightly and heated in a closed tube to produce di-and tri-isobutylene.  (6) The acid liquor is heated without dilution, whereby the proportion of tri-isobutylene is increased slightly.

Title: Improvements in or relating to methods of manufacturing wound capacitors
IPC: H01G13/00
Filed: 1961-03-15
Abstract: 897,477. Capacitors. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 15, 1961 [March 18, 1960], No. 9495/61. Drawings to Specification. Class 37. A method of manufacturing rolled capacitors comprises the steps of (a) winding the capacitor rolls from a given length, or to a given number of turns, of pre-stretched foils of synthetic material and electrodes capable of being deformed when the foils contract, the number of turns or length of foils being chosen so that the inequality holds in which Cn = nominal desired capacitance Cw = average capacitance of untreated wound rolls T = permitted tolerance in nominal value S = maximum relative increase in capacitance value upon thermal treatment of rolls-calculated on initial value D = maximum relative decrease in capacitance on thermal treatment-calculated on initial value. (b) Subjecting the rolls to a thermal treatment until maximum capacitance is obtained, and (c) subjecting the rolls, if necessary, to a further thermal treatment dependent on the difference found between the capacitance value and the desired nominal value and adapted to this difference in a manner such that the capacitance of the majority of the rolls is brought to the desired nominal value within the tolerance permitted. The rolls are preferably wound from prestretched foils of polystyrene and foils of a soft deformable metal such as lead-tin. Any batch of capacitors are wound to have an average capacitance before treatment of Cw where Cw satisfies The number of turns or length of foils and also S, D are found by experiment if necessary. The rolls are subjected to heat treatment in a furnace at a temperature of 104� C. for about 30 minutes to produce the initial increase of capacitance S and after this initial treatment are conveyed to an automatic sorting device which sorts the rolls according to their capacitance values. Short-circuited rolls and those of capacitance values less than (1 - T)Cn or more than (1+T+D)C)Cn are rejected. Rolls of capacitance value in the range Cn(1�T) are accepted and supplied to a finishing off line. The remainder of the rolls, i.e. those between (1+T)Cn and (1+T+D)Cn are subjected to further thermal treatment the duration of which increases with the difference between the actual capacitance of the roll and Cn, the automatic sorting device assigning each roll to one of a number of furnaces adapted to give appropriate thermal treatment. The number of such furnaces increases as the tolerance T becomes smaller. The rolls leaving the fournaces are tested and if there has been no substantial lowering of the capacitance value they are rejected, otherwise they are re-tested in the automatic sorting for re-assignment.

Title: Improvements in package binding implement
IPC: B65B13/28
Filed: 1923-04-09
Abstract: 219,065. Cary, S. C., and Cary Manufacturing Co. April 9, 1923. Wire strainers for securing wires around bales &c. A common operating member is movable at will to actuate either the tensioning means or the twisting and severing means. In one construction, Figs. 1 and 2, the heads to which the ends of the wire are anchored are moved relativelv to one another by a screwed shaft, and in another construction, Figs. 7 and 8, these heads are moved by actuation of cam surfaces. In the first construction the pre-deformed end, x<1>, of the wire is inserted in a slot in a stationary member A, the wire is passed through a slotted pinion (not shown), housed in the member A, around the bale and again through the slotted pinion, and the other end is anchored to a pin 0 on the movable head N. The normal position of the apparatus before tension is applied to the binder is shown in Fig. 2. Rotation of the shaft H by the handle h, with the gears J, K in mesh. produces movement of the head N to impart the desired tension to the wire. The shaft H is now pushed inwards against the spring N<1>, as shown in Fig. 1, to disconnect the gears J, K and to. engage the gear G with an intermediate gear F meshing with the slotted pinion. Further rotation of the common operating-shaft H twists the ends of the wires together, and, at the proper time in the cycle, a cam on the shaft depresses a pivoted knife P to sever the space wire between the slotted pinion and the head N. The head N is made in two superimposed parts pivoted together, each part being provided with a semicircular screw-threaded recess to receive the screwed shaft L. A guide rod m<2> is also provided. In the second construction, Fig. 7, the ends of the wire are gripped or held by devices A, B with which are associated rollers i2. The rollers coact with the cam peripheries of a flanged disc W, Fig. 8, which is rotated in one direction by the forward throw of a bifurcated lever L to cause the rollers to separate and so to tension the wire, an annular externally toothed gearwheel 28 that fits in a channel in the flange w being held stationary for the time being. On the reverse stroke of the lever the wheel 28 is rotated relatively to the flanged disc, which now remains stationary, to rotate a slotted pinion 27 to twist the ends of the wire. A pivoted cutting blade is also actuated in the cycle to sever the spare wire.

[Also in Groups XL (a) and XL (b)] A method of making an inter-digital metalstructure, e.g. a wave-retarder for an oscillator, having metal-fingers projecting from different sides of a channel-shaped base-member, includes forming a channel 3 with slotted sides 2 in a metal, e.g. copper, base-member 1, Fig. 3, fixing into aligned slots finger-blanks 4 of copper or molybdenum, each having a cut-out portion 5, embedding the blanks in a dispersable solid-support-medium 6, separating the supported blanks into two parts at the cut-outs 5 by removing the top portions, so producing projecting fingers, Fig. 7, and then dispersing the support medium. During machining of the channel 3 the previously-formed slots 2 are filled with a synthetic resin supporting medium similar to that used for embedding the blanks 4. The resin may be a polymerized ethylene or a methyl methacrylate polymer, or alternatively the support medium may be type-metal. Dispersal of the support medium may be by heat, a solvent or a chemical reagent. The finger blanks may be brazed, soldered or welded to the base member, either prior to embedment in or after the removal of the support medium 6. Where slots 2 and the channel 3 are cut to the same depth, finger blanks with an additional cut-out at the bottom may be used.

[Also in Group XXXV] A permanent magnet system having an adjustable magnetic shunt is employed in a mass spectrograph or the like for deflecting the beam of ions. Permanent bar magnets 1-4, (Fig. 2), are arranged side by side between end cheeks 5 of the magnetic system having pole-pieces 7, the arrangement being arcuate to correspond with the beam path. The end cheeks have extensions on the opposite sides of the magnets from the pole-pieces, connected by a non-magnetic cylinder 9 having non- rotatably mounted in it by longitudinal keys and guideways 15, a cylindrical block 11 which is caused to partially or wholly bridge the end cheeks by a hand-driven leadscrew 12 passing through the block. In the minimum shunt position the block is contained in an annular extension cap of one cheek. A rack-and-pinion mechanism may adjust the magnet system along rails 21 in the plane of the magnetic gap. Two shunts in parallel may be employed, one for fine control. In a modification the cylindrical block has an external thread engaging in a threaded hole in one cheek and is adjustably screwed into an annular extension of the other cheek, which is slotted or castellated or has varying thickness to give a more open or linear scale of adjustment near the maximum shunt position. Specification 522,731, [Group II], is referred to.

Title: Improvements relating to printing

Filed: 1962-03-14
Abstract: 958,709. Automatic registration control. EVERSHED & VIGNOLES Ltd. May 9, 1963 [March 14, 1962], No. 9846/62. Heading G3R. In a system for automatically adjusting the register of impressions printed by rolls, a photoelectric cell responding to register marks printed by the rolls controls a gating circuit so that a number of pulses corresponding to the distance between the marks is derived from a generator driven at a speed proportional to that of the printing machine, and passed to a counter which compares them with a desired number and controls the register if there is any error. As shown rolls 2, 3, 4 printing different coloured impressions on a web of paper 1 are driven by an electric motor 6 through differential gears 7, 8, 9. A photoelectric cell 15a responds to register marks printed on the web by rolls 2 and 3 and controls a gating circuit 23 so that pulses from a generator 13 driven by motor 6 are applied to a counter 22 from the time that photo-cell 15e detects a mark made by roll 2 until it detects a corresponding mark made by roll 3. The number of these pulses is thus representative of the relative position of the two marks and if this number differs from a number corresponding to the correct relative position, counter 22 applies a digital error signal to a store 28a. This signal is converted to an analogue signal by stage 31a which determines the speed and direction of a servomotor 12 correcting register by adjusting the speed of roll 3 through differential gear 8. In a similar manner a second photo-electric cell 15b in the same lateral position as photo-cell 15a detects the relative position of marks made by rolls 2 and 4 and controls the register of roll 4 by means of a servomotor 12b. The two detectors and servo-systems are selected in sequence by unit 18 which also clears stores 28a, 28b periodically. Counter 22 resets automatically if the number is unduly high e.g. due to reading the marks in the reverse order. Initial setting of the rolls to approximate register may be effected manually or partially automatically by substituting for the photo-electric detectors, magnetic pick-offs associated with the rolls and appropriately delaying the signals therefrom. The Specification also refers to lateral staggering of photo-cells each of which is associated with and views only marks made by, one roll. Use of a single photo-cell and use of register correcting bars is also possible.

Abstract: 926,281. Centrifugal separators. FOSTER WHEELER Ltd. March 14, 1962, No. 9851/62. Class 23 [Also in Group XIII] In a centrifugal separator, Fig. 3, a mixture of steam and water is whirled by vanes 46 as it passes from the upper end of a vertical inlet conduit 36 into an open-ended whirl chamber 38 which converges upwards so that the separated water is prevented from overflowing its upper edge and flows through an annular passage 40 into a surrounding open-ended tubular baffle 42 where any steam still present in the water is separated and leaves upwardly through an annular passage 44 while the water is evacuated downwardly. A further set of vanes 48 is provided at the outlet of the passage 40 to project the water substantially horizontally against the wall of the baffle to facilitate separation of the entrained steam. A number of separators may be mounted on a cup-shaped baffle 24 in a vertical boiler, Fig. 1, in which water circulates outside U-tubes 12 carrying the heating fluid. The mixture of steam and water produced within the baffle passes through the separators from which the steam flows towards a drier 32 and out through the boiler shell 10. The water evacuated from the separators is returned, with the feed water entering at 22, through an annular passage 26 into the lower open end of the baffle 24.
