Abstract: 1,200,821. Inking apparatus. GESTETNER Ltd. 31. Jan., 1969 [22 Feb., 1968], No. 8764/68. Heading B6C. A collapsible ink tube is slid laterally into an open-sided jaw integral with clamp body 7, and movement of operating lever 4 raises body 7 to abut against support 2. Ink pipe 8 is fast with support 2, and movement of body 7 forces the ink tube into engagement with pipe 8. If the ink tube is partially but not wholly inserted into the jaw, feeler 16 contacts it as lever 4 is moved. Feeler 16 may be integral with lever 4, and has a bevelled lower edge. Either the tube resists feeler 16, so that movement of lever 4 and body 7 is halted, or the bevelled lower edge of feeler 16 forces the tube fully into the jaw and movement continues. Alternatively the operating lever may actuate a separatelypivoted feeler. Inking apparatus of the above kind is stated to be suitable for use in a stencil duplicator.

Patent GB-637107-A (GB)
Title: Improvements in or relating to machines for filling bottles or the like with liquids under pressure
IPC: B67C3/08
Filed: 1947-04-02
Abstract: 637,107. Bottling. CHELLE, P. L. April 2, 1947, No. 9026. Convention date, Dec. 9, 1946. [Class 125(ii)] In an automatic rotary machine for filling bottles or the like with gassy liquids under pressure, of the type in which filling heads are arranged around a central collector tank, an individual intermediate container is interposed between the tank and each filling nozzle, each of the intermediate containers being successively initially supplied with liquid from the tank under the effect of hydrostatic pressure alone after balancing of gas pressures, and thereafter the corresponding bottle being put under the pressure of the intermediate container and filled with liquid therefrom under simple gravity effect, the escape of the air contained in the bottle being effected through the intermediate container to atmosphere without passing through the tank. As shown, rotation of the machine causes the carbon dioxide counterpressure atmosphere of central collector tank 7, Fig. 1, to be connected to the atmosphere of an intermediate container 13 via a distributor valve 31 and flexible pipe 14, and a check valve to be operated by a stationary cam 65 to allow liquid to flow from collector 7 into containers 13 via a flexible pipe 15 until the liquid levels are the same in both collector and container. Gas and liquid connections are then closed and the filling spout, together with container 13, lowered onto a bottle 17. Engagement of the funnel 89 of the filling spout with a bottle neck operates a linkage to rotate a valve-operating cam 118 in a valve casing 101 surmounting container 13, Fig. 8. Rotation of cam 118 first lowers a check valve 111 to connect the bottle with the counterpressure atmosphere in container 13 via a tube 80 and channels 109, and then lowers a head 107 and tube 80 to open an obturating valve 123, thereby allowing liquid from container 13 to flow into the bottle through a tube 79, the air in the bottle being displaced into container 13. On completion of filling, container 13 and the bottle are vented via a pipe 14, distributor 31 and a vent pipe 52 terminating in a needle valve 53, Fig. 1. Further stages of decompression in the bottle are provided as the spout rises, by escape of gas at the spout, and by enlargement of the heat space in the bottle. In the absence of a bottle, cam 118 is not operated, and neither liquid nor gas escapes from container 13. Liquid is supplied to tank 7 from a saturator 25, and gas from carbondioxide containers 24.

Title: Process for treating cellulose and for the manufacture of cellulose in the form of powder
IPC: C08B1/00
Filed: 1951-04-23
Abstract: Cellulose with a reduced degree of polymerization is produced by passing cellulose containing not more than 35 and preferably not more than 10 per cent of moisture one or more times through the nip of one or more pairs of closely spaced hard-surfaced hollow rolls through which cooling water is passed, the nip clearance not exceeding 0.05 mm. and preferably not exceeding 0.02 mm., and the rolls of each pair of rolls rotating at different peripheral speeds with respect to each other, so that the temperature of the cellulose is raised sufficiently to cause the cellulose to become brittle and the rolled product consequently becomes disintegrated into flakes.  The flakes may be ground in a mill into a powder free from fibres.  Preferably sheets of cellulose 0.5-3 mm. thick are passed singly through the nip of the rolls.  In the example sheets of chemical wood pulp containing 9 per cent of moisture, based on dry cellulose, and 0.9-1.2 mm. thick, are passed 4 times through the nip of a pair of rolls each 7 cm. in diameter, rotating at 23 and 18-19 r.p.m. respectively and having a nip clearance of 0.01 mm.  The rolls are cooled with water having an inlet temperature of 13 DEG  C.  After the treatment the D.P. of the cellulose has decreased from 900 to 750.  The cellulose to be treated may be in the form of continuous strips, and the nip clearance of successive pairs of rolls may decrease. The cellulose may be in the form of cotton linters or fibres or refined wood pulp flakes.  Specification 683,385 and U.S.A. Specification 1,910,406 are referred to.

Title: Improvements in and connected with signal control arrangements for railway depots and the like
IPC: B61L1/20
Filed: 1937-04-03
Abstract: 492,197. Railway signals. STANIER, W. A., BARNES, F. S., and HENDERSON, P. L. April 3, 1937, No. 9500. [Class 105] For the protection of working gangs engaged on a train in a carriage siding a number of lock mechanisms with electric switch devices are provided so that a danger signal is given when any one of the devices is operated but the clear signal is not given until all the lock mechanisms have been restored denoting that all the gangs have left the train. A number of such devices may be arranged at different points along the siding. The devices comprise mercury switches each controlled by a pair of interlocking revolving-barrel locks. The foreman of a gang inserts and turns his key in-the lock 1 whereby the companion lock A is freed so that it can be turned and its key extracted ; the foreman's key remains locked in the barrel lock 1. The turning of the lock A operates a mercury switch C to break contacts c<1>, c<2> and to make contacts c<3>, c<4>. From Fig. 5 it will be seen that the clear signal lamp G is lit only if all the mercury switches C are closing their contacts c<1>, c<2> whereas the danger signal lamp R is lit if any one of the switches is closing its contacts c3, c<4>. Thus the first gang causes the danger signal R to be lit. Further gangs perform similar operations at the same or different locations in the siding. The foremen's keys for the locks 1, 2, 3 may be of the same form but carry identification marks whereas the keys of the locks A, B, C are of different form. Fig. 4 shows the interlocking mechanism for the barrels of the two locks A, 1 in the position in which the lock 1 is held locked with the key therein. The interlocking mechanism comprises plates f, j, each with curved and straight edge portions. The plate j cannot be turned until the straight edge f<1> of the plate f is moved out of the way. Such movement of the plate f is effected by the foreman re-inserting the previously extracted key into the lock A and turning the barrel, such movement being possible by reason of the curved edge 1a. Thereafter the barrel of the lock 1 can be rotated and so free the foreman's key. The two plates are also notched at k to co-operate with a locking plug l carried by a spring m. In a modification using only one switch, Fig. 6, the barrels of the locks A, B, C have arms s engaging in slots t of a bar u so that downward movement of any arm s depresses the bar u to operate the switch r; the bar remains down until all of the locks A, B, C have been restored. According to the Provisional Specification a sliding bar such as is shown in Fig. 6 may be locked in its depressed position by a number of padlocks.
