Title: Improvements in and relating to the manufacture of artificial silk and like products
IPC: D01F2/10
Filed: 1929-01-25
Abstract: 328,627. Dreaper, W. P. Jan. 25, 1929. Indiarubber sheets and threads.-Filaments, yarns, staple fibre, or films are obtained from solutions of viscose or cuprammonium cellulose containing rubber latex by the wet ' or precipitation process and sulphur required for vulcanization is precipitated in and on the products either at the time of their formation or subsequently. Vulcanization is brought about in the presence of an accelerator or super accelerator with or without an antiager, which may be added to the cellulose solution or subsequently applied to the products. The products may be caused to react with formaldehyde, and may also be dyed before or after vulcanization. The precipitation of sulphur is regulated by the composition of the precipitating bath, the composition of the viscose solution or by additions to the same. To enhance the deposition of sulphur, sodium sulphite may be added to the viscose solution which is then coagulated in an acid bath. In the case of cuprammonium solutions, a substance. may be added to the solution and the coagulating bath so chosen as to give, rise to precipitation of sulphur. The amount of latex present must not be so high as to interfere with the process of filament or film formation. In an example, an 8 per cent solution of cellulose in the form of viscose, and 0.8 per cent of rubber latex is formed into filaments and coagulated under such conditions that an amount of sulphur equal to 10 per cent of the amount of rubber is precipitated in the filaments. The washed filaments in skein form are immersed in diphenylguanidine solution, or other accelerator, hydroextracted and then vulcanized at a temperature not exceeding 90‹ C. According to the Provisional Specification, sulphur required for vulcanization may also be obtained by volatilizing sulphur compounds on to the filaments.

IPC: H04J1/16
Filed: 1951-02-02
Abstract: 696,913. Two-way transmission; carrier transmission. STANDARD TELEPHONES & CABLES, Ltd. Feb. 1, 1952 [Feb. 2, 1951], No. 2655/51. Class 40 (iv). In a multi-channel telephone network comprising a multiplex system or a group of audio channels, two-way connections between two stations are grouped in pairs and supervisory signals in one direction for both connections of a pair are transmitted over one connection and supervisory signals in the reverse direction for both connections are transmitted over the other connection. In the two-wire system, Fig. 2, both-way connections 1 and 2 over pairs 4, 6 and 5, 7 respectively have a carrier channel bandwidth of 3400 cs. and the band above 2800 cs. is used for the supervisory signals which comprise a 2940 cycle signal for connection 1, a 3180 cycle signal for connection 2 and a pilot current of frequency 3060 cycles. The signal carrier generator, Fig. 4 (not shown), comprises a 3060 cycle oscillator and a 120 cycle oscillator feeding a modulator from which the signalling frequencies are derived by filters for keying by, for example, dialling impulses in static modulators. The receiver, Fig. 5, includes an amplifier 49 provided with automatic gain control by rectified pilot current and two relay circuits in which a relay is included in the anode circuit of a valve which is also biased by the rectifier pilot current through rectifier 55. The valves are also provided with additional bias to obtain freedom from distortion by making the anode current half its maximum when the signalling wave passes through zero. Cross talk and false operation are avoided by having the signalling frequency for the channel over which it is being transmitted adjacent to the audio channel. This arrangement also facilitates a more economical filter. In a 4-wire system, Fig. 3 (not shown), the signalling is transmitted by the " Go " line of one connection and the return line of the other.

Title: Improvements in film feeding means for photographic cameras
IPC: G03B27/58
Filed: 1942-03-03
Abstract: 553,688. Roll-film holders for photographic cameras. PHOTOSTAT, Ltd., and DANIELS, A. March 3, 1942, No. 2823. [Class 98 (i)] A roll-film holder with means for attaching it to the back of a camera has a film feed locking device including a releasable latch element carried by a member forming part of an external operating member which is manually operable to retract the pressure pad and to disengage the releasable latch element from a co-operating latch element which upon rotation with a film winding shaft, maintains the pressure pad in the retracted position. The roll-film holder shown comprises a casing, which is provided with slides 4 which are slid into the chann is provided on the camera body for the plate or cut film holder. The film passes from a spool 13, under tension produced by rollers 23 or a shaft carried by spring-pressed arms 26, over a guide roller 14, through guiding channels 15, over a second guide roller 16, between spaced plates 17, 18 and feed rollers 19 and pressure rollers 20, and through a slot in the back of the casing to a removable box 54. The pressure rollers 20 are mounted on spring-urged pivoted arms 28 which can be lowered by pivoted cams 31 to separate the feed and pressure rollers when inserting a film. The feed rollers 19 are rotated through one turn by a handle 34 to feed a new exposure area of the film into position, but are normally held against rotation by a latch lever 37 on a rock-shaft 39, which is urged by a spring 41 to hold a pin 36 in a notch 38 in a disc 35 carried by the shaft on which the rollers 19 are mounted. Before a feeding-movement can be effected the lever 37 must be rocked by a lever 40 on the shaft 39 to disengage the pin 36 from the notch. The lever 37 at the same time, through a pin and slot connection 41, 42, moves a rod 7 to the rear against the action of a spring 11, so withdrawing from contact with the film a pressure plate 6 secured to the rod. Or completion of one revolution of the feed rollers the pin 36 falls into the notch 38, so locking the feeding means and allowing the pressure plate 6 to move into contact with the film. The film passes between the upper blade 43 of a guillotine cutter, which is slidable downwardly by an operating lever 52, and the lower fixed blade 44. The filmreceiving chamber 54 is attached to the filmholder by slotted brackets 65 engaging pins on the sides of the latter. A slot in its front wall for the passage of the film is closed by a shutter 56 on a rotatable and axially-movable rod carrying an arm on which is a pin 59. When the chamber is in position the rod is rotated to open the shutter, in which position it is held against the action of a spring by the engagement of the pin 59 with a socket on the side of the film holder.
