Abstract: 1434782 Water-soluble polyamides WOLFF WALSRODE AG 26 Feb 1973 [26 Feb 1972] 9297/73 Heading C3R [Also in Division B2] A method of preparing a water-soluble copolyamide comprises polycondensing a mixture comprising (a) 35 to 45 wt. per cent of one or more polyalkylene polyamines, (b) 45 to 60 wt. per cent of one or more dicarboxylic acids and (c) 5 to 20 wt. per cent of hexamethylene diammonium adipate or 5 to 10 wt. per cent of aminocaproic acid or caprolactam, and crosslinking the resulting polycondensate with 0À1 to 0À4 mol epichlorohydrin per mol equivalent of secondary amino groups in the polycondensate. Preferred reactants are (a) di - to tetra-ethylene trito penta-amine and (b) adipic, azelaic, sebacic and terephthalic acids. In the examples the polycondensate is subjected to reaction with epichlorohydrin as a 25% aqueous solution and the product diluted to 10% for use. The product is stated to improve the wet-strength of cellulose-containing materials, e.g. sausage casings, and particularly to provide an effective anchor layer on sheet structures of such materials to promote adhesion of polymers, especially vinylidene halide polymers thereto. Reference is made to Specifications 1,065,363; 3,250,664 2,926,154; 1,906,561 and 1,696,248. Reference has been directed by the Comptroller to Specification 1,284,935.

Abstract: 587,776. Girders, beams, &c. TRUSSED CONCRETE STEEL CO., Ltd., and GREEN, D. H. May 16, 1944, No. 9329. [Classes 20 (ii) and 20 (iv)] Girders with "ladder" sides (a sinuous metal lattice welded between straight metal chords) have a timber fixing attached, between one edge of one ladder and one edge of another ladder, by metal pins traversing the timber and secured to the edges of the ladders. The metal ladders, which may have angle or T irons in place of the edge rods 1, 2, may be produced on a machine such as is described in Specification 565,797, [Group XXII], and in welding thereto the pins 7 (which may lie outside, or alternately outside and inside, the edge rods instead of all inside as shown), the edge rods adjacent to the welding heads may be pressed tightly against the timber fixings 6 to pre-stress the pins. The timber fixings may be continuous or in short lengths, and in a box beam, sinuous metal lattice may replace one of the timber fixings, or may be provided on all four sides, the timber overlying the lattice. End shoes (not shown) may be attached to the ends of the beams to hold them during welding, to give rigidity to the ends of the beams, and, being suitably holed, to provide a means of attachment.

Title: Method and means of making pouches
IPC: B31B23/00

Abstract: 526,712. Cutting indiarubber &c. YEATES, P. M., and JACKSON, D. D. March 25, 1939, No. 9398. Convention date, June 20, 1938. [Class 31 (i)] [Also in Group XVII and V] Relates to apparatus for making pouches, for tobacco &c. from a continuous strip of moistureresistant material which will adhere by heat and pressure, such as indiarubber, by folding the strip longitudinally, sealing it transversely at intermittent points and severing it through the seams. Sheet material from a roll 5 is passed over a plate 7 having a V-shaped lower edge and is drawn laterally so as to fold the sheet, between rollers 12, under a roller 13, and over a roller 15 against which it is pressed by a spring-mounted roller 35. The strip passes beneath a roll 42, and between rotating devices 46 formed with plates 48, Fig. 6, the edges 49 of which register so as to press the strip transversely at intervals. The plates 48 are fitted with electric. heating-elements 58. The strip is drawn on to a roll 65 together with a separating strip drawn from a roll 67. The pressed strip is subsequently drawn from the roll, the separating strip being rewound, and passes in the reverse direction through the apparatus. It is severed by passage between rollers 76, the upper one of which is formed with a recess 80, Fig. 8, carrying a knife 81, the diameter of .the rollers being such that at each revolution the knife engages the folded strip along the middle of the sealed transverse portion. Rotary brushes behind the rollers 76 serve to separate the pouches and discharge electricity. The pouches are carried away by conveyers 85.

Abstract: 1486860 Cams; linkwork MEYER ROTH & PASTOR MASCHINENFABRIK GmbH 6 March 1975 [20 March 1974] 9418/75 Heading F2K [Also in Division B3] A welding machine for the electric resistance welding together of rod ends, particularly the ends of pre-curved chain links 3, comprises an upsetting arrangement 4-14 for acting on the respective rod ends, and the upsetting tools 4, 5 are moved in dependence on a movable cam 18 which has, over a partial region of its control contour 20, at least one adjustable contour element 23 so that the characteristics of the welding operation, e.g. upsetting pressure and/or welding current flow, can be adjustably set. The upsetting arrangement is spring biased by springs 15 to a maximum upsetting pressure and the cam 18 acts through bell crank lever 13 to relieve the spring force during the positioning of a link 3 on a saddle 2, and then with current supplied to electrodes 1 the upsetting force is applied as the cam is rotated and the contour element 23 engages a roller 17 of the bell crank lever 13. The element 23 may be of corrugated or wave-like contour to bring the rod ends together and then withdraw them in a flash-butt welding operation. The element 23 is pivotally connected at one end to the cam and has an adjusting device 24, e.g. a screw, at its other end. The cam may have at least two elements 23 of different length and contours mounted in the cam and being selectively used as the operating cam contour. In an alternative embodiment (Fig. 3, not shown) the upsetting force is not supplied by the spring 15 and the lever 13 acts directly on the yoke 12. The cam may also include correction elements which modify the contour of the contour element 23.

Abstract: Those documents (a, b) which are guided on rails (1) along a track and are to be removed from the stream of transported documents, for example banknote prints with faults, are distinguished by metal marks (a', b'). They are identified by a metal detector (2) which, in a downstream subatmospheric pressure suction device (13), actuates a magnetic valve (18), by means of which the identified document is picked up by a subatmospheric pressure cylinder (4) and transported into a magazine (6). Upstream, in the transport direction of this removal device, all documents are counted in a counter (25) by means of a photoelectric detector (9') interacting with a light source (24'). Furthermore, the identified documents which are picked up by the removal device are guided past a photoelectric cell (7) on their way to the magazine (6) and counted in a counter (8). <IMAGE>

IPC: H02H7/125
Filed: 1956-03-27
Abstract: 848,444. Protective cut-out arrangements. ENGLISH ELECTRIC CO. Ltd. March 27, 1957 [March 27, 1956], No. 9605/56. Class 38 (5). [Also in Group XXXV] A rectifier protective arrangement includes circuit elements forming a current path preferentially responsive to A.C. potentials of supply frequency between a point at earth potential and a point connected with a D.C. output terminal of the rectifier installation. The rectifier 15 may be a mechanical or contact rectifier and may supply an electro-chemical plant 10 through bus-bars 11, 12. The current path includes an inductor 22 and a capacitor 23 forming a series-resonant circuit in series with a bridge rectifier 25 which supplies a low-set alarm relay 26 and a higher-set circuit-breaker tripping relay 27. This protective arrangement may be tested by a test-circuit which includes an A.C. supply source 33, a test switch 38, a capacitor 34 and an inductor 35. One such protective and test arrangement is connected between the positive bus-bar 11 and an earth bus-bar 24 and another such arrangement is connected between the negative and earth bus-bars so that the existance of an A.C. potential supply frequency to earth on either the negative or positive busbar causes an alarm to be given and the circuitbreaker 16 to be tripped if the A.C. potential is of sufficient magnitude. The provision of an ammeter 39 and a voltmeter 40 enables the leakage resistance to earth to be calculated when the test circuit is used, the test circuit applying an A.C. potential between the appropriate supply bus-bar and the earth bus-bar.
