Title: Improvements relating to tube cutting means for tube winding machines
IPC: B23D25/04
Filed: 1960-09-22
Abstract: 959,788. Shearing. E. W. RONAI. Sept. 22, 1960 [Sept. 22, 1959], No. 32564/60. Heading B3W. Tubes 6 wound by a machine B are severed by a machine A comprising pivoted disc-cutters 43 carried at intervals on an endless conveyer 31, and means 49 for extending the cutters in succession to perform severing operations as the conveyer is moved in synchronism with the movement of the tube along a revolving mandrel 5. The chains or, as shown, the steel band of the conveyer is supported on pulleys 14, 16 on a carrier 25 which is adjustable vertically by a screw 22 operated through bevel-gears by a handle 19. Pulley 16 is adjustable by a screw 30, and the pulley 14 is driven through gearing 8-13 by an electromotor (not shown), the drive speed being synchronized electronically with that of a motor 54 driving the winding machine B, as by photo-cell means co-operating with marks on the tube. Overhead roll supports 29 for the tube are adjustable along the feed-path. The disc-cutters 43 rotate on ballbearings 44, Fig. 3, in links 40 which are biased by springs 47 about pivots 45 in carriers 32. These have slots 34 for the conveyer band 31 and wedges 35 operated by screws for securing the carriers to the band. Guides 37, 38 are provided at the sides of the carriers, which have nylon blocks 36A at their lower corners. Supported from the guide 38 is a cam 49 against which a roller-follower 46 on each link 40 is pressed by the springs 47, the cutter 43 severing the tube while the follower 46 is on the rise of the cam. Flexing of the conveyer band between carriers 32 is controlled by blocks 55.

Title: Improvements in or relating to the colouration of fabrics made of or containing cellulose esters
IPC: D06P5/22
Filed: 1929-10-26
Abstract: 339,429. British Celanese, Ltd. Oct. 26, 1928, [Convention date]. Cellulose esters.-In dyeing fabrics made of or containing cellulose esters or machines of the winch type, the formation of creases is avoided by partially saponifying the ester before dyeing. The saponification may be effected in any suitable way, e.g. as described in Specifications 304,596, 309,377, 314,447, 316,521, and 318,468; as saponifying agents, sodium or potassium hydroxide, carbonate, phenolate, sulphite, and silicate, and trisodium phosphate are mentioned. Additions such as soap, sodium acetate, borax, or alcohol may be made to the saponifying bath, and the temperature of the bath may be such that the material is simultaneously delustred. The method is applicable to heavy materials and materials containing highly twisted yarns. An example is given in which a cellulose acetate fabric is scoured in an aqueous bath containing olive oil soap and a dispersion of xylene in turkey red oil, partially saponified after addition of caustic soda to the bath, and then dyed on a winch. The treatment of materials made of or containing cellulose formate, propionate, or butyrate is referred to.

Title: Process for the polymerisation of cyclic lactams of ªÏ-amino-carboxylic acids
Inventor: HAMANN ADOLF
IPC: C08G69/18
Filed: 1954-11-10
Abstract: Lactams of o -amino carboxylic acids containing seven or more ring atoms are polymerized with an alkali metal hydroxide by submitting part of the lactam together with the alkali to intense gassing with an inert anhydrous gas at a temperature above the melting point of the lactam, the resulting reaction mixture containing an intermediate polymerization promoting compound then being mixed with the remainder of the lactam and polymerized.  The gassing may be carried out at or below the polymerization temperature.  Specified lactams include e -caprolactam, enantho lactam, heptane acid lactam and c -octane acid lactam whilst nitrogen is specified as the gassing agent.  In the examples: (1) sodium hydroxide and e -caprolactam are subjected to gassing at 120 DEG  C., polymerization being effected at 240 DEG  C.; (2) potassium hydroxide and e -caprolactam, both stages being effected at 240 DEG  C.; (4) sodium hydroxide and e -caprolactam are subjected to gassing at 125 DEG  C., polymerization being effected at 260 DEG  C., both stages being continuous.  In all four examples, nitrogen is the gassing agent.  Specification 762,443 is referred to.

Title: Improvements in and relating to magnetic storage devices
IPC: G11C11/06
Filed: 1964-08-11
Abstract: 1,056,789. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 19, 1963], No. 32645/64. Heading H3B. [Also in Division H1] Information is stored in a magnetic memory element by remanent fluxes having the same orientation but different distributions. Element 10 has a wire W for generating a first magnetic field and a wire B connected to generators 28, 30 for supplying both positive and negative pulses thereto. However, as described, the device is capable of use with pulses of only one polarity to permit a uni-polar output to be produced, as claimed in Specification 1,004,932, and four different read-write cycles for generating unipolar outputs are described each being preceded by a positive clearing pulse on wire W. In the first a " 0 " is written by a positive pulse on wire W and a " 1 " is written by positive pulses on both wires W and B, the B pulse having a smaller amplitude than the W pulse and terminating after it. This causes some of the lines of flux 34 to traverse the magnetic core material above wire B, as at 36 (Fig. 4c, not shown). For read-out a positive pulse of lower energy content, but possibly greater amplitude or duration, than the write pulse is applied to wire W to disturb flux lines 36 and generate an output pulse in wire B when a " 1" is stored, without destroying the information. In the second arrangement the same pulses are applied to wire W but to store a "1 " a negative pulse is applied to wire B. The sense of the output pulse during readout is then reversed. The third arrangement uses a negative pulse on wire W for storing a "0," combined with a positive B pulse for storing a "1." The write pulse on wire W has a lower energy content than the clear pulse. The negative read pulse applied to wire W may have a greater energy content than the write pulse but should not exceed the energy of the clear pulse. The fourth arrangement is similar but uses a negative pulse on wire B for storing a " 1." For producing a bi-polar output a " 0 " and " 1 " are stored using positive and negative pulses on wire B in conjunction with the write pulse. It is stated that element 10 may consist of non-remanent material overlaid with a remanent layer. A magnet matrix store is described.

Title: Production of improved polymers
IPC: C08F10/00
Filed: 1958-10-15
Abstract: In the manufacture of solid olefin polymers using a solvent and a particulate chromium oxide catalyst followed by recovery of the polymer from solution, the solution of polymer containing suspended catalyst is subjected to centrifuging to give a solution of reduced chromium concentration and one of higher chromium concentration, the reduced chromium concentration solution being then mixed with a filter aid and filtered, so further reducing the chromium concentration.  Two centrifugal stages may be used, the higher chromium concentrate from the first being diluted and passed to the second, and the second reduced chromium concentrate recycled by blending with the solution fed to the first centrifuging operation.

IPC: C23C22/82
Filed: 1964-08-13
Abstract: A method of treating a ferrous surface comprises forming a zinc phosphate coating thereon and then making the coated surface a cathode in a zinc phosphate solution so that zinc is deposited thereupon.  The phosphate coating may be formed by dipping in a zinc phosphate bath, e.g. suspended from an electrically conducting support so that current may be switched on through the support and both processes carried out in the same bath; or by spraying with zinc phosphate solution and subsequently dipping the ferrous article in the reservoir of the spray solution where it is brought into contact with an electrical conductor, thereby effecting the deposition of the zinc.  The phosphate solution may contain 0.5-3.0% w/v phosphate, calculated as PO4, and have a free phosphoric acid content of 0.3 to 0.8%.  Electrolytic deposition of the zinc preferably takes place at a temperature of 70 DEG -160 DEG F. and using a current density of below 30 Amps/sq. ft., preferably 5-15 Amps/sq. ft.
