Title: Producing Filamentary Materials by Fibrillation
IPC: D01D5/00
Filed: 1967-08-23
Abstract: 1,165,934. Forming filamentary materials by fibrillation of films. CELANESE CORP. 23 Aug., 1967 [12 Sept., 1966], No. 38818/67. Heading B5B. A fibrillated product is produced as a continuous operation by extruding in film form a mixture of a molten synthetic thermoplastic filament-forming polymer and a minor proportion of a blowing agent or foaming agent which at the extrusion temperature is itself a gas or evolves a gas, drawing the extruded film as it leaves the extrusion die and continuing the drawing while the film is maintained at a temperature above the glass transition temperature of the polymer until fibrillation occurs and solidifying the fibrillated film. The fibrillated product obtained may be twisted and then subjected to further drawing. The process of the invention is generally applicable to synthetic thermoplastic synthetic resins which can be shaped by melt extrusion. Particularly suitable are polyethylene, polypropylene, polystyrene and polymethyl-3-butene. Suitable resins include polyamides, acrylic resins, oxymethylene polymers, halogenated polymers, and polycarbonates. Cellulose esters of for instance acetic acid, propionic acid and butyric acid may also be used. As blowing agent there may be used any of the well-known foaming agents for polymers. In general, finely divided solids or liquids which vaporize or decompose with formation of gaseous products at the extrusion temperatures, as well as volatile liquids, may be used. In the example, a mixture of molten polypropylene of 1À7 intrinsic viscosity and 1% by weight of azodicarbonamide is extruded through a die have a 1 Î 0À020 inch extrusion slot at a rate of 2À5 grams per minute and the extruded film is maintained at a temperature above the glass transition temperature of the polymer by directing jets of air on the the upper and lower surfaces of the film. The film is then passed over a first roll at a speed of 25 to 35 metres per minute,whereby a fibrillated product is obtained. A portion of the undrawn unoriented product is heat relaxed at 120‹ to 130‹ C. Another portion is drawn at a draw ratio of 2À5 while passing over a " shoe " heated to 130‹ C. A portion of the drawn product is twisted 5 turns per inch and drawn at a draw ratio of 1À7 while passing over a shoe heated to about 140‹ to 150‹ C.

Title: Ophthalmic glasses with variable light transmissive lenses
IPC: G02B5/23
Filed: 1976-09-21
Abstract: The lens comprises a basic lens body (18) which is covered by a first layer (14) made from a solid persistently electrochromic material, and a second layer (12) made from an ion-conducting material. On their outside, the layers each bear an electrode (10, 16) for generating an electric DC voltage field. The electrochromic material becomes coloured in accordance with the field strength. By setting the DC voltage at the electrodes (10, 16), it is thus possible to vary the optical absorption of the lens. Such controllable lenses are used chiefly as spectacle lenses for spectacles which have a variable light transmittance. <IMAGE>

Title: Diffraction grating
Inventor: STAUNTON JOHN J J
IPC: G02B5/18
Filed: 1961-11-06
Abstract: 977, 340. Diffraction gratings. COLEMAN INSTRUMENTS CORPORATION. Nov. 6,1961, No. 39641/61. Heading G2J. The spread of the blaze of an expellets grating is increased by providing each working surface with more than one blaze angle. Each working surface may be divided into two distinct planes as at 1-2, 2-3 &c. in Fig. 2 by moving a conventional diamond cutting tool from right to left of the grating so that deformations are formed at the ridge between the grooves during each pass. In an alternative form, the two planes are as at 8-6<1> and 6'-7 in Fig. 3. A grating of this form is produced by first cutting the usual grooves 4-8-4<1>, 4'-8'-4" &c. and then changing the tool angle and aligning the tool with the peaks 4, 4<1>, 4<11> before making a second cut during which the upper part of the fan 8-4<1>, 8<1>-4<11> &c. is turned over. The grating may have carved working surfaces, these being produced by rotating a grooved grating relative to a metal source and evaporating the metal (e.g. aluminium) so as to build up metal over the top of each groove. Alternatively the original grooves may be partially filled in with gelatin or an epoxy or polyester resin 9, Fig. 5, which may be cast on in liquid form and allowed to harden.

Title: Improvements in or relating to auxiliary apparatus for teleprinters for the automatic ciphering of messages
IPC: H04L9/18
Filed: 1958-12-16
Abstract: 910,648. Telegraph ciphering apparatus. ANSTALT EUROPAISCHE HANDELSGESELLSCHAFT. Dec. 16, 1958 [Jan. 7, 1958], No. 40576/58. Class 40 (3). In a ciphering and deciphering apparatus means responsive to a predetermined signal change the connections in the apparatus from the ciphering condition to the deciphering condition. The ciphering unit is provided with a selectively operated by-pass connection, the by-pass being switched in automatically if said signal is received while the ciphering unit is operating. In one embodiment, Fig. 1, during transmission a teleprinter at A passes signals to relay ER. Mark and space potentials are thereby passed to five capacitors C via a distributer. Each capacitor C feeds a by-pass switch D which applies the potential on C either via a distributer to relay SR or through contacts l and v to the distributer and relay SR. Contacts l and v are controlled by a cipher tape scanner and by a mechanical key, respectively. Contact sr causes signals to be transmitted on line B, the signals being in cipher or in clear dependent on the position of switch D. The apparatus is set to its receiving state a predetermined time after the end of a transmission by means of relay NG. During reception switches U 1  and U 2  are reversed, teleprinter A printing the received signals, after deciphering if necessary. If while the apparatus is transmitting in cipher, a special and predetermined signal is received on line B it is detected by unit K which reverses contacts U 1  and U 2 , and also sets switch S to the by-pass state. This is of use where, for example, the transmitter and receiver cipher tapes lose synchronism, the receiver then indicating that it wishes to correspond with the transmitter in clear code by sending the special signal. The signal further causes a visible and audible alarm S to be operated, and also opens switch Q so that message signals from the teleprinter A are not fed to the apparatus. In conditions of strong interference in the transmission path it is desirable to prepare a tape record of the ciphered message so that it may be repeated several times. This reduces synchronization problems that would arise if the message were ciphered each time it was repeated. To obtain the ciphered tape switch LO is reversed, signals from the teleprinter at A then being ciphered and recorded on a tape perforator connected at A. Should signals arrive on line B during this operation relay UE is operated, this energizing alarm S. Fig. 2 illustrates a modification to part of the apparatus of Fig. 1. Here the message is fed in from a tape scanner E, which controls the potential fed to the cipher tape scanner L, rather than from a teleprinter at A as in Fig. 1. The mechanical key is at V.
