Title: Spinning young viscose
IPC: D01F2/06
Filed: 1947-10-15
Abstract: Viscose containing about 7-8 per cent of cellulose and 4-13 per cent of sodium hydroxide, and having a salt point between 8 and 18 and at least 1.19x, where x is the percentage of sodium hydroxide, is extruded at 45-50 DEG  C. into an aqueous spinning bath containing between 1.2x and 2x per cent of sulphuric acid and at least 21+0.66x per cent of soluble sulphates, the bath containing at least 18 per cent of sodium sulphate and at least 1 per cent of zinc sulphate. The filaments are then stretched by 90-110 per cent, products of high tenacity and high wet and dry extensibilities, useful for the production of type cords, being obtained.  Viscose of the characteristics set out above may be unripened viscose, or viscose to which a ripening retarder such as sodium sulphite has been added, or ripened viscose which has been re-xanthated by addition of carbon bisulphide prior to spinning. The sulphate content of the bath may consist solely of sodium sulphate and zinc sulphate or may include sulphates of other polyvalent metals such as iron, magnesium, chromium, cadmium, manganese, nickel and aluminium.  The stretching of the filaments is effected in known manner, optionally with the aid of a plasticizing agent such as hot water or steam.  In a typical example, viscose containing 7.5 per cent of cellulose and 13 per cent of sodium hydroxide, and having a salt point of 15.5, is extruded at 45 DEG  C. into a bath containing sulphuric acid 19.3, sodium sulphate 20 and zinc sulphate 9.6 per cent, and the filaments are stretched by 110 per cent in a hot water cascade between two godets.

Title: Improvements in or relating to closure means for openings in walls of chambers arranged to contain gas under pressure
IPC: F23M7/00
Filed: 1946-09-16
Abstract: 626,322. Furnaces. BABCOCK & WILCOX, Ltd. Sept. 16, 1946, No. 27720. Convention date, Sept. 21, 1945. [Class 51 (i)] [Also in Group XVIII] Closure means for an opening in the wall of a furnace chamber comprises a door, a valve controlling a supply of elastic fluid and adapted when open to establish a fluid pressure opposing the ejection through the opening of gas from the chamber, means adapted to inhibit movement of the door from its closed position while the valve is closed and means adapted to prevent operation of the valve by its operating handle while the door is in a normal open position. As shown in Fig. 4, a circular door-frame 34 comprises a conical wall portion 37 joined by a shoulder 39 to a cylindrical portion 38 and surrounded by a peripheral manifold 41 from which holes 42 in the shoulder portion 39 communicate with the central passage 36 of the frame. The frame has two hollow projections 48, 49, (Fig. 3) the interiors of which communicate with the manifold 41 and which house respectively a hinge pin 53, about which is pivoted a door 26, and a catch pin 54. When the door is closed it is held against the frame by springs 61 acting through the catch pin and the hinge pin. When the door is to be opened a valve key is inserted through hole 67 in the door and valve 45 is opened, admitting to the manifold compressed air which discharges through the jet holes 42 and prevents the ejection of furnace gases. At the same time the air pressure within the manifold forces the hinge pin 53 and catch pin 54 outwards against the springs 61, releasing the door which when the valve key is removed drops open and covers the valve, preventing further access to the valve until the door is replaced over the opening.' In closing, the procedure is reversed. Specification 598,141 is referred to.

Title: Improvements in or relating to photographic cameras
IPC: G03B7/12
Filed: 1959-08-14
Abstract: 883,679. Cameras. GAUTHIER G.m.b.H. ALFRED. Aug. 14, 1959 [Sept. 26, 1958], No. 27800/59. Class 98(1). A photographic camera comprises setting devices for the lens aperture and exposure time, these devices being coupled by a differential gear, the intermediate gear part of which is mounted on a movable carrier: the above arrangement is such that, when the exposure time has been pre-set the lens aperture is set automatically, the exposure time setting device remaining stationary, by the movement of the gear carrier which is controlled by a stop associated with a light intensity measuring device. As shown in Fig. 1, a ring 1 controls the shutter speed setting (read on scale 3) and its movement is limited by stops 7. A ring 2 controls the diaphragm aperture over a range indicated by scale 5 and controlled by stops 7. A film sensitivity indicator 10 may be coupled to the ring 1 by means of an end 13a of a rod 13 engaging notches in the ring 10. These rings can be uncoupled by pressing rod 13 so that end 13a releases ring 10 but engages a part 8c of a rod 8 which carries a ratchet wheel 9 which is part of the differential gearing connecting rings 1, 2, 10 when operating the device ring 10 is set to the required value relative to shutter speed setting ring 1, but movement of ring 10 causes ring 2 to move. Ring 10 is connected via cam surface 10c and pin 31 to a device, for example two pointers, which co-operates with the pointer A (not shown) of a light intensity measuring device so that only if the pointer A is between the other two pointers can the ring 2 be set to an aperture within the operational range of the camera. If the above adjustment of ring 10 causes the pointer A to move outside the region between the two pointers, ring 1, when coupled to ring 10, can be moved to bring it back into that region. The diaphragm aperture may be set automatically by arranging that the rod 8 is spring urged to the left (Fig. 1) but is held by a pawl 40a connected through a delay device to the shutter release knob, until the shutter is released. The distance rod 8, and hence the diaphragm control ring 1, is moved and controlled by a stop 16a which engages one of a number of steps 8a on the rod 8 (Fig. 2) the position of-stop 16a being determined by a light meter which causes lever 16 to rotate about point 17.

Title: Improvements in or relating to arrangements for selecting electric pulses according to amplitude
IPC: H04J7/00
Filed: 1945-10-26
Abstract: 602,059. Pulse discriminating circuits. STANDARD TELEPHONES & CABLES, Ltd. Oct. 26, 1945, No. 28427. Convention date, Nov. 2, 1944. [Class 40 (vi)] To separate desired pulses from others of greater amplitude, all the pulses are clipped at a level slightly greater than the amplitude of the desired pulses, the pulse portions so removed are combined with the original pulses so as to produce pulses of altered width corresponding to the undesired pulses, pulse sections of different width being derived by gate clipping the combined pulses, and the sections having widths corresponding to the desired pulses are selected. In one embodiment, pulses of smaller amplitude than the desired pulses are removed by a biassed amplifier 4, Fig: 1, and pulses of greater than the desired amplitude produce an output from the biassed-back valve 5, the output pulses being distorted by the integrating condenser 9 and combined in circuit 15 with the output from amplifier 4 after inversion in circuit 14. The leading and trailing edges of the undesired pulses are thus distorted and after clipping all the pulses between two amplitude levels in circuit 41 they are applied to a pulse width discriminator 46. The latter may be a known shock-excited tuned circuit, Fig. 3 (not shown), which produces output pulses of maximum amplitude from pulses of the undistorted width which are operated by a further clipper circuit, and represent the desired pulses only. A differentiating circuit 26 may be interposed between the mixer 15 and clipper 41 to produce shorter pulses of widths different for desired and undesired pulses. In a second embodiment, Fig. 4 (not shown), the portions clipped from the pulses of greater amplitude than the desired ones are delayed and distorted before mixing with the original pulse train.
