Title: Method and apparatus for processing glass yarn
IPC: D02G1/02
Filed: 1965-07-13
Abstract: In a method of false-twist crimping of glass yarn, a protective lubricant, e.g. a high molecular weight polyalkylene glycol, is applied to the tensioned yarn between a zone in which the twist is heat-set, e.g. at 1100 DEG F, and a cooling zone preceding the false-twister. On the downstream side of the twister, the untwisted or untwisting yarn, passing (through advancing nip rollers also serving as a twist-stop or directly) to a wind-up package, may be treated with a stiffening agent or size, e.g. sodium alginate, polyvinyl alcohol, paraffin wax, and/or heated. The latter treatment may dry or set the agent, or the remanent tension in relaxed yarn may be sufficient, to hold or retain the crimp as a latent property which may be released at a later, e.g. finished fabric, stage.

Title: Method of welding thermoplastic material
IPC: B29C53/00
Filed: 1967-04-05
Abstract: In a method of welding together members made of thermoplastic material by first heating portions of the members to a welding temperature and then pressing these portions together, mould parts are applied to each side of the portions to prevent the thermoplastic material from spreading perpendicular to the direction in which the portions are pressed together and the portions are then pressed together with a pressure of from 10 to 100 kg. per sq. cm. The members may be butt welded or lap welded together and the portions may be heated by infra-red or other radiation, by contact with a heating element, by a flame or by induction heating. In one embodiment, Figs. 1 and 2 (both not shown), the edge portions of two sheets (1), (2) of hard polyvinyl chloride are heated to welding temperature and are abutted in a mould comprising a U-shaped trough (3) having a lid (4) secured thereto by locks (5) or clamps. The sheets are pressed together by a force (F) which at the weld produces a pressure of 10-50 kg. per sq. cm. if the mould has been preheated to a temperature which is at least halfway between room temperature and the welding temperature and at most 10 C. below the welding temperature and a pressure of 20-100 kg. per sq. cm. if the weld has not been preheated. In a further embodiment, Fig. 3, the end portions 6a, 7a of two polyethylene tubes 6, 7 are heated to a welding temperature and then abutted in a mould formed by metal cylinders 8, 9. A force F is applied either by means of pressure plates 10 or rings 11 and produces a pressure at the weld in the ranges specified above. In another embodiment, Fig. 5, a polypropylene tube 13 is welded into the wall of a tube 12, an opening being simultaneously or subsequently cut in the tube 12 through the tube 13. Preheated cylinders 14, 15, 16 form the mould and a force F is applied to a pressure ring 18. In a still further embodiment, Fig. 6 (not shown), portions (19a), (20a) of hard polyethylene sheets (19), (20) are heated to the welding temperature and overlapped. Metal bars (21), (22) serve as mould parts and the welding force is exerted on pressure plates (23), (24).

Title: Encoder having an analog input signal centering arrangement
IPC: H03M1/12
Filed: 1967-11-21
Abstract: In an encoder for converting analogue signals into a symmetrical binary code, the zero level of the input signal is adjusted to lie in the centre of the code range by a feed-back between the digit output and the input, having means for examining the polarity of each of the successive channel codes, means assigning a polarity to a block of channel codes, means for generating a corresponding analogue bias signal which is applied to the input to equalize the number of channels having opposite polarities. The digital outputs are each preceded by a polarity signal which are gated by gate 10 to a counter 9 the output of which indicates whether the majority in a group of channel codes is positive or negative. Flip-flop 6 is set in one state or the other and integrator RC to a bias signal generator 8 to apply a signal to the input at 3. The whole block of channels may be divided into m groups of n channel codes, each n channel codes being examined as before to see whether the majority is positive or negative and the outputs are applied to a further counter indicating whether the majority of the n groups has a positive or negative preponderance. The counter adapted to indicate whether the majority of n polarity signals is positive or negative has a capacity of (n + 1), n being odd. The capacity will be exceeded or not to give the required indication.

Title: Method and Device for Producing Prefabricated Building Elements in a Tiltable Mould
IPC: B28B1/16
Filed: 1967-12-09
Abstract: Prefabricated building elements are cast in a tiltable mould which can be rotated from a horizontal to a vertical position for unloading. As shown, the apparatus comprises a transfer table 39 mounted on rails 49 for carrying the mould from moulding to unloading stations and a manipulator 31 for moving the mould transversely and tilting it at the unloading station. The mould 10 has a mesh base 18 through which water can be extracted by suction from pumps 18, vibrators 13, a removable side 16, on which the finished unit is removed from the mould and sealing blocks 19 to make the mould airtight when a further mesh with extracting means 22 is lowered on to and clamped to the mould. The element is cast with the surface that will form the outside at the bottom of the mould. A filler cloth is laid on the mesh base 18 and a layer of plaster 1 is applied thereto, the layer being levelled by movement of the mould assembly along the track 49 under a spreader. A layer of concrete 2 is laid on the plaster, a heat insulation insert and reinforcement 3 are laid on the plaster and the mould is vibrated. The evacuation system 12 may also be switched on to draw water out of the concrete. The mould is then filled level with its top by a layer of concrete 4. Vibration lowers the level of the concrete layer 4 and the mould is filled with a layer of "warm" plaster 5. A filter cloth is laid on the plaster surface, the mould is closed by upper section 28 and the mould is vibrated and suction applied to reduce the water content of the element. The upper section 28 and filter cloth are removed and the mould is filled with a second layer 6 of "warm" plaster 6. When the element has set sufficiently, the mould is carried by transfer table 39 to the storage bay and is moved transversely from the transfer table on the manipulator 31 from which the mould is tilted on to side 16 of the mould, this side being left as a stand for the element. This method of stacking allows the outer plaster surface 1 to be worked to any desired finish the inner surface 6a butting against a previously moulded element.

Patent ES-365387-A1 (ES)
Title: Optical data recording
IPC: G11C13/04
Filed: 1969-03-28
Abstract: A method of holographically recording data comprises bringing together at a recording medium 12 a reference beam 13 and a data beam 10, wherein the transmitted part of the reference beam 15 is redirected through the medium 12 at a location continuing to receive the data beam. The redirected reference beam may be caused to retrace its original path through the medium, or it may return along its original path in the reverse direction. In reconstruction the reference beam follows the same paths as the original reference beam 13 and consequently forms two coincident vertical images at the location of the original object or data source. The transmitted part of the beam 15 may be redirected by a plane mirror 16. If the mirror and reference beam source, laser 14, are interchanged real images are set up. The data record can be used to align optical apparatus by comparing the coincidence of the real or vertical image and the original object. In an alternative embodiment the recording medium is located between a pair of concave mirrors, one of which has an aperture for passage of the reference beam. This beam is caused to re-pass through the medium several times, always from the same side, the number of passes being determined by the resolution of the medium. A further embodiment replaces each concave mirror by two orthogonal reflecting surfaces, the transmitted part of the reference beam repassing the recording medium alternately through opposite sides.

Title: An article o a moving support surface in the form of a continuous web a sheet orapparatus for applying adhesive tape particulare self adhesive tape t
IPC: B65C1/02
Filed: 1969-11-14
Abstract: An apparatus for applying lengths of adhesive tape 30 to a moving surface 2 comprises rollers 23-26 for drawing the tape 29 from a roll 28, reversing mechanism 55, 57 and a rotatable applicator foot 14. The rector-shaped applicator foot 14 is driven from a driving shaft 8 through a lost-motion coupling at a peripheral speed slightly less than that of the surface 2, so that after it has initially applied the leading end of a severed length of tape 30 to the surface it is rotated by frictional contact with the tape to press the entire length of the tape on to the surface. Feed rollers 24, 26 are driven intermittently from the shaft 8 by way of a crank and one-way clutch drive. Friction in the oneway clutch causes the rollers to be given a slight reverse rotation during reverse movement of the crank arm to an extent permitted by play between abutments of a friction brake provided on the output side of the one-way clutch. This slight reverse movement of the feed rollers prevents the leading edge of the unsevered tape from adhering to the reversing mechanism 55, 57. The reversing mechanism has a stationary blade 55 and a pivoted blade 57 which is actuated by a cam on the driving shaft.
