Abstract: 1465038 Crimped polyolefine filaments JAMES MACKIE & SONS Ltd 21 March 1974 [22 Dec 1972 13 Aug 1973] 59318/72 and 38228/73 Heading B5B A tow containing crimped filaments of semicrystalline polyolefines or blends of polyolefines with other filament forming materials is formed by spin drawing the polyolefin, rapidly and assymmetrically cooling a proportion of the filaments from the molten state, heat treating a formed tow of filaments to at least 100‹ C. and drawing the tow so as to form at least 2 crimps per cm. Rapid cooling is such cooling as to produce a neck portion of length "C" in filament 35 such that C is less than 50 times the full diameter of the filament. Cooling is effected by a jet of air directed at the filaments preferably directed obliquely at 40 m./sec., as the filaments leave the spinneret plate and heating prior to drawing is effected by passage through an oven or a heated bath or by passage over a heated surface. Snubbing means are used to control the level of tension running back into the heat treating zone and some of the drawing rollers may be immersed in a heated bath. The filaments may be heat treated in a relaxed state after drawing and may further be mechanically crimped subsequent to drawing and prior to the heat treatment.

Patent GB-656194-A (GB)
Abstract: 656,194. Counting-apparatus. COMMERCIAL CONTROLS CORPORATION. March 5, 1948, No. 6906. Convention date, March 7, 1947. [Class 106 (i)] [Also in Group XVI] A postage meter machine (see Group XVI) comprises ascending and descending registermechanisms to register the amounts of postage printed on the letters passed through the machine. Both registers are operated manually by three knobs which at the same time set the printing wheels for stamping. The operation of the two register-mechanisms is the same and only that of the descending register 80, Figs. 20 and 23, is described. The knobs each actuate through gearing one of the shafts 606, 608, 610 carrying setting-wheels 612, 614, 616, each aligned with one of the setting-wheels such as 618 of the register-mechanism. Each register setting-wheel has associated with it a cam slot which as the wheel rotates acts to move outwards a number of radially seated pins 624 in a member rotatable with the printing drum on the shaft 42. The number of pins protruding is equivalent to the setting of the corresponding knob, and on rotation of the drum, the pins of each setting-wheel act through gears such as 626, 628 to actuate the corresponding counterwheel 650 to register the amount set up on the selected knob. When the drum rotates, a roller 642 moves out of a notch 646 in a disc 644 to hold a lever 638 against wheels 632, 634, 636 on the shafts 606, 608, 610 and thereby hold the wheels 612, 614, 616 in correct alignment. The descending register is provided with a zero lock comprising a lever 652 having a comb 654 which is moved by a spring 656 into notches 650a in the three highest order counterwheels when the notches come into alignment. When this occurs, a bell-crank 658 moves clockwise into a recess 652b of the lever 652, and a lever 664 moves anticlockwise to prevent the actuation of the machine. During a printing cycle, the roller 642 abuts the lever 652 and prevents the actuation of the lock. To reset the register, a cover-plate 680 is moved to the left by a pin 684, when a tongue 680c engages the bell-crank and turns it anticlockwise to allow the machine to be actuated, and a pin 691 moves the comb 654 out of the notches 650a. The counterwheels can then be reset with a stylus. The plate 680 is then moved to the right to align the window 693 with the top digits on the counterwheels.

Patent GB-2001577-A (GB)
Title: Manufacturing thin- walled articles
IPC: B29C48/07
Filed: 1978-07-24
Abstract: A method for manufacturing thin- walled articles, for example cups and plates, by thermoforming a sheet of crystalline thermoplastics material which has a critical crystalline melting temperature range. The method includes temperature conditioning the sheet for thermoforming, and the conditioning comprises developing a preliminary temperature profile across the sheet such that the core part of the sheet is at a temperature lower than the said range, the outer surface regions of the sheet being at a still lower temperature. A final temperature profile for thermoforming is developed by reheating the outer surface regions to a temperature such that those regions become at least elastically deformable, the core part being kept in an elastically deformable state at a temperature lower than the said range.

Title: Apparatus for and method of dividing gas-filled glass tubing
IPC: C03B23/18
Filed: 1979-06-26
Abstract: In an apparatus for and method of dividing gas-filled glass tubing, particularly where the tubing is filled with a radioactive gas, division is effected by drawing the glass tubing (6) through opposing laser beams (19, 20) at a rate low enough so that at least opposing faces of said glass tubing are each divided and each sealed to the other in a single pass through said laser beam. The glass tubing is contained within a pressurized chamber (1), the pressure in said chamber being greater than that within the tubing, even when the tubing is heated by the laser beam. Where the side walls of the tubing are not completely divided in a single pass, the glass tubing is taken through the laser beam for a second pass, complete division being effected in no more than two passes. A plurality of tubes (6) can be held in a single holder (5) and cut in a single pass, or, at most, in two passes, so that the production rate achievable by the apparatus and method is high. <IMAGE>
Patent GB-2025101-A (GB)
Title: Detection of failure of consumers of electrical current
IPC: G01R31/00
Filed: 1979-07-09
Abstract: To detect the failure of e.g. a lamp (2) supplied from a D.C. source (4) through a switch (3) controlled by a manually-operated member (5), a resistance (1) of much greater value than that of the lamp (2) is connected across the switch (3), and the voltage V1 across the resistance (1) is used for the required detection. If the lamp (2) goes open circuit, then when the switch (3) is non-conductive the voltage V1 is low instead of high, while if the lamp (2) is short circuited then when the switch (3) is conductive, due to the finite resistance of the switch (3), the voltage V1 is high instead of low. To ensure failure detection regardless of the condition of the control member (5), the switch (3) is caused cyclically to incurse momentarily into the opposite state from that dictated by the control member, so that either type of failure can always be detected; appropriate clock pulses are supplied from a generator (6). The equipment is particularly suited to detecting the failure of lights on a motor vehicle. <IMAGE>
