Title: Improvements in and relating to the indicia marking of regenerated cellulose and to the production of packages of such material having indicia marking thereon
IPC: B44C1/00
Filed: 1935-11-18
Abstract: 462,563. Printing processes; embossing; bronzing and the like. SALFISBERG, L. L. Nov. 18, 1935, No. 31869. Convention date, Nov. 22, 1934. [Class 100 (ii)] [Also in Group XVII] Regenerated cellulose is marked by changing the refractive index of a selected area by the application of heat. The method may be combined with the methods of packaging described in Specifications 438,076 and 441,315, [both in Group XVII]. As shown, a web 3 is led from a roll 1 over idlers 4, 5, 6 to the package-forming rollers 13, 14, where another similarly fed web 10, from the other side of the machine, is incorporated, with the tablets 11, to form packages. A roller 40 is mounted on a shaft 44 supported between the members of a yoke 41 pivoted at 42. An extension of the shaft 44 is engaged by a cam 37, at each revolution of which a raised portion thereof lifts the roller 40 into the position shown. Further revolution allows the roller to descend into engagement with the web, a spring 54 assisting the action. The roller 40 is heated by an electrical heating element 60 and is provided on the surface with raised portions corresponding to numbers or other indicia which it is desired to impress on the web. A similarly mounted and actuated roller 40a is provided with complementary recesses. The heating is sufficient to produce an oxidation which changes the physiochemical character of the web and alters the index of refraction to make the area visible. The rollers are rotated between each step by means of a ratchet 46 on the shaft 44, engaged by a pawl 50 on an arm 48 loosely mounted on the shaft and positioned to engage with a pin 49 on the frame. The appearance of the strip as it passes through the machine is shown in Fig. 5. The portion c represents the web before arriving at the rollers 40, 40a, the section d shows the web marked with numbers, and the section e represents the completed package sections in which the strips 3, 10 have been united to enclose articles 11 surrounded by further oxidized embrittled areas m. In the form shown in Fig. 7, the marks, in this case representing the number 100, are formed by modifying the rollers 13, 14, the rollers 40, 40a being dispensed with. In order to produce colour effects, the arrangement shown in Fig. 8 is used. A roller S3, having a soft rubber periphery, is rotated in a container 84 containing finely divided gold, silver or aluminium. An intermediate rubber roller 82 transfers the material on roller 81. The rollers 80, 81 are similar to the rollers 40, 40a except that instead of a series of consecutive numbers, similar numbers occur entirely round the periphery of each roller.

Abstract: 618,158. Rotary disc valves. STILL & SONS, Ltd., W. M., and STILL, F. W. Oct. 28, 1946, No. 31947. [Class 135] [Also in Group VI] A semi-rotatable ported disc valve is spring- pressed at its centre against a seat so as to be free to tilt to adjust itself to the seat; the latter is in the form of a readily removable ported washer. In a coffee infusing-machine, hot water passes from a boiler by way of a pipe 8, Fig. 2, and duct 14, to the disc valve 6, and in either of the two extreme positions of the valve is conducted by way of two cavities 25, Fig. 6, in the face of the valve disc, to a duct 11 leading to the infuser. At the same time the infuser discharges by way of a duct 15 and a cavity 26 to one or other of ducts 21 or 22 leading to separate coffee receivers. In the intermediate position of the valve, Fig. 5, the infuser is connected by way of duct 15 and a duct 24 within the valve disc to a duct 17 leading to a drain. The operating spindle 37 is connected to the valve by one or more pins 37a passing loosely through a keeper 29. The latter transmits the force of a compression spring 35 to the centre of the valve disc by means of a pointed projection 28 which engages a conical recess on the valve disc so as to press the disc against a non-metallic ported washer 43. The latter stands proud of thin tubular thimbles 43a pressed into the duct ends. A further spring 40 holds a rotatable extension 39 finoly against the valve body 5 ; a ball bearing 41 may be interposed. An indexing pin 32 on the valve disc works between two pins 33; alternatively, the pin 32 may be angular and enter an arcuate recess.

Patent GB-341890-A (GB)
IPC: C08B3/22
Filed: 1929-10-21
Abstract: In making laminated glass a cellulose derivative is first subjected to the action of a bleaching agency, then removed from the sphere of action of such agency and used as the basis of the strengthening layer or layers.  The cellulose derivative may be cellulose nitrate or organic cellulose esters such as cellulose acetate, cellulose formate, cellulose butyrate and cellulose propionate, or cellulose ethers such as ethyl, methyl or benzyl cellulose.  The cellulose derivative may be bleached while in powder form or in the form of sheets or films or in solution. The bleaching agency may be either physical such as exposure to ultra violet light, or chemical, preferably treated with an oxidizing agent such as nitric acid, hydrogenperoxide, potassium or sodium dichromate, or potassium or sodium permanganate.  The cellulose derivative is preferably purified by filtering a solution thereof.  The reinforcing layers may contain plasticizers such as camphor, triacetin, diethyltartrate, dibutyl tartrate, diethylphthalate, diphenylol propane and may also contain natural or synthetic resins.  In preparing the solutions, solvents such as acetone, chloroform, methylene chloride, diethylene chloride, ethyl alcohol, methyl alcohol, benzene, or mixtures of these solvents may be employed.  Medium boiling solvents such as ethyl lactate, or high boiling solvents such as diacetone alcohol may be employed. Stabilizers such as urea and pigments or dyes particularly of a violet tint may be employed.  In one example a solution of 1 part of cellulose acetate and 9 parts of acetone is filtered and treated with one third of its volume of 3 per cent hydrogen peroxide.  The cellulose acetate is then precipitated from the solution by the addition of distilled water, filtered, washed, dried, worked into a sheet, inserted between adhesive-coated glass sheets and pressed. The cellulose acetate may contain 60 per cent of triacetin and a synthetic phenol-formaldehyde resin may be employed as an adhesive. In another example 200 litres of a 10 per cent solution of cellulose acetate in acetone is treated with a solution of 4 litres of concentrated nitric acid, 2 litres of concentrated hydrochloric acid and 20 litres of water.  The cellulose acetate is then precipitated with water, washed and dried and the laminated glass completed as in example 1.  Specifications 299,065 and 299,066, [both in Class 2 (iii), Dyes &c.], also are referred to.

Abstract: 1,097,230. Transferring data between memories. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 19, 1966 [July 29, 1965], No. 32355/66. Heading G4C. In data transfer apparatus for transferring data between first and second memories with effective word lengths a and b respectively, an address of the first memory is multiplied by (a/b) to produce an integer and a fractional remainder, the second memory being addressed in accordance with the integer and bytes being transferred between the memories in accordance with the remainder. The remainder selectively operates gates interconnecting sections of two one-word buffer registers respectively associated with the two memories. The invention enables waste of storage space to be avoided by permitting words of one memory to overlap word boundaries in the other. In the case of overlap, the remainder automatically causes an extra memory access to access the next word position. The hardware could be complicated for unsuitable values of (a/b) in which case the ratio could be made suitable by wasting some memory space.
