Abstract: 1,143,569. Cutting &c. apparatus. F. J. EDWARDS Ltd. 8 Dec., 1967 [7 Sept., 1967], No. 40943/67. Heading B4B. [Also in Divisions B6 and F2] Apparatus for cutting or scoring sheet material comprises pressure rollers 1, 2, Fig. 1, having an adjustable gap therebetween, a table 10 on which rests a base-plate 11 for supporting the material, and a plate 15 pivotally coupled to a pulling block 12, the plate 15 having strip steel knives 16 mounted thereon and a pivoted guard 8 resting thereon, the arrangement being such that at the start of a cutting &c. operation, the plate 15 and guard 8 are raised to their upper setting position so that the material can be placed on the plate 11 after which two push buttons A, B, Fig. 4, are operated simultaneously, so as to be operable only by the use of both hands, to start a reversible electric motor 31 to lower the plate 15 and guard 8 to their lower setting position and cause a reversible electric motor 4 to be started to rotate the rollers 1, 2 to feed the block 12 and therewith the unit formed by the plates 11, 15 and the material through the rollers 1, 2 so that the knives 16 are caused to cut or score the material, the rollers 1, 2 continuing their rotation until the unit actuates a limit switch LS5 to reverse the motor, the rollers 1, 2 then feeding the unit back to its original position to close limit switches LS3 and LS4 and cause the plate 15 and guard 8 to be raised to their upper setting position so that the material can be removed from the plate 11. Material is stripped from the knives by means of a stripper plate (19), Fig. 3 (not shown). A limit switch LS1 is positioned between the guard 8 and the plate 15 and has its contacts closed when the guard rests on the plate. A limit switch LS2 serves to stop the motion of the unit through the rollers 1, 2 if the guard 8 is raised. The plate 15 and guard 8 are raised by means of rollers 25 carried by arms 24 mounted on a shaft 23 on which is also mounted an arm 26 secured to one end of a chain 27 which passes over sprocket drums 28, 29, the drum 29 being fixed to the shaft 30 of motor 31, the shaft 30 having fixed thereto a disc 32 carrying a cam 33 for a " down " limit switch LS6 and an " upper " limit switch LS7. Fixed to the shaft 23 is a further arm 35 in the path of movement of which, when the plate 15 and guard 8 are in their raised position, extends a spring-influenced bolt 16, the bolt being retracted when both buttons A, B are depressed. After the buttons A, B are depressed, either a fully automatic cycle can be carried out or each portion of the cycle can be initiated by hand by operating a switch C, Fig. 4, to convert from automatic to manual cycling, then operating buttons D, F in succession after which the switch C is operated to restore it to automatic cycling. Actuation of a push button E enables the motion of the apparatus to be stopped at any stage. The circuitry is illustrated in Fig. 5 (not shown).

[Also in Division D1] A sheet-like product is made by taking off from a spinneret having orifices of 0À1 to 1À5 mm. diameter bundles of continuous thermoplastic filaments each containing 3 to 50 monofilaments at a speed of between 1000 and 5000 metres per minute to a residual elongation of 150 to 500% and a breaking strength exceeding 2À5 g./den., randomly depositing the bundles of filaments on a moving support to form a web, and subjecting the web to superatmospheric pressure, preferably between 5 and 500 atmospheres gauge while the web is held at a temperature which is below the melting-point of  the filaments. The web is preferably conducted between a heatable rotating roll and a support which travels in synchronism with the roll, so that the web and support contact the roll for 30 to 80% of the circumference of the roll. The surface of the roll or the support preferably has a Shore hardness below 90. The process may be carried out on the apparatus described and illustrated in the parent Specification. The thermoplastics which may be used include polyamides, polyesters, polyolefins, polyurethanes, and polyimides as well as copolymers thereof.

Abstract: 1,227,264. Stripping cables. PRESSLUFTSTOLZEL oHG. 3 June, 1969 [14 June, 1968], No. 27932/69. Heading H2C. Coaxial cable ends are prepared by parallel knives 5 ... 11 in a carrier 1 when carriage 12 is reciprocated with respect to the knife carrier in a direction parallel to the cutting edges of the knives so that the cable is rolled between the carriage and the carrier which are spaced apart by a distance equal to the cable outside diameter D. This spacing may be adjusted by wedges 2, 3 and the carrier 1 complete with knives may be interchangeable to suit various cable types. The knives are arranged to project from the carrier surface to depths corresponding to the depths of the desired steps in the cable end, and subsequent stripping of the insulation is facilitated by longitudinal cuts made by knives 17, 18. If a symmetrical knife arrangement is used with a central knife 8 which cuts right through the cable, two cable ends are prepared simultaneously. The rolling action of the cable is assisted if the surface of the carriage and/or knife carrier is roughened. The reciprocating motion is conveniently produced by an electric motor and a crank (13, Fig. 1, not shown), and may be stopped by a limit switch at the end of a cycle. The advancement of the cable through the device may be similarly automated.

Abstract: 1,229,336. Polyurethane mastic. RHONE. POULENC S.A. 12 March, 1969 [12 March, 1968], No. 13133/69. Heading C3R. Polyurethane mastics are prepared in a twostage process by first reacting a macrodiol with a polyisocyanate in an amount such that there are 1 to 2 isocyanate groups per hydroxyl group and for sufficient time for at least 95% of the hydroxyl groups to react to produce an isocyanate - terminated prepolymer and then adding a polyaryl polyisocyanate obtained by the phosgenation of an aniline-aldehyde polycondensate. The macrodiol is suitably a polyoxyalkylene glycol or a polyester and the polyisocyanate used in the first stage is different from that added in the second stage. Fillers, pigments, plasticizers, diluents and catalysts may be added to the reactants used in making the mastics. In a typical example, a polyoxypropylene glycol is reacted with 80/20 2,4- and 2,6-toluene diisocyanate to form a prepolymer to which is added a commercial polyaryl polyisocyanate.

Abstract: 1,250,085. Magnetic storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 13 Nov., 1969 [16 Dec., 1968], No. 55562/69. Heading H3B. In a magnetic storage arrangement, a storage location defined by the crossing point of orthogonal conductors 3, 7, comprises a number of thin, magnetically anisotropic films 2, 4, Fig. 1, having different critical switching fields H K , so that by applying a particular sequence of pulses to the conductors each film may be made to store a different bit of a word. In Fig. 1, the films are separated by a non-magnetic material 5, which may be electrically conducting, and each of films 2 is magnetically coupled to a correspondingly disposed and magnetically similar one of films 4. Alternatively, Fig. 4, the films 4 may be replaced by a single film 8 whose cross-sectional area equals the total cross-sectional area of films 2. The magnetic flux paths around the films and conductors may be closed by keepers 15, 16. To write into the structure of Fig. 4, a pulse 17, Fig. 6A, of sufficient magnitude to switch all three films 12, 13 and 14 to the hard direction is applied to word conductor 3, overlapping with a pulse 18 on conductor 7 which establishes a tipping field along the easy axis. When pulse 17 is terminated, the three films have a common direction of magnetization along the easy axis which represents a " 0 " or a " 1 " depending on the polarity of pulse 18. The operation is repeated, using a pulse 19 of such lesser magnitude that only the two most easily switched films are affected, the tipping pulse 20 being shown with a polarity opposite to that of pulse 18. To write into the third film, a smaller pulse 21 is applied on conductor 3, with a coincident pulse 22 on conductor 7. Reading is carried out by reversing the pulse sequence in conductor 3, giving output pulses 26, 27 and 28 in conductor 7. The operations may be speeded up by using a descending or ascending staircase waveform in place of the discrete writing or reading pulses of Fig. 6A, as in Fig. 6B (not shown). A method of making the storage locations in multiple by vapour deposition is described, the films of least H K  lying furthest from conductor 3. The films are of Permalloy, and the variation of H K  is achieved by choice of cobalt concentration. The films may have different widths, Fig. 3 (not shown).
