Title: Method of printing on transparent material
IPC: B41M1/30
Filed: 1954-03-04
Abstract: 739,836. Printing-processes. TRANSART AKTIEBOLAG. March 4, 1954 [Oct. 23, 1953], No. 6315/54. Drawings to Specification. Class 100 (2). A method of printing on thin transparent material, such as cellulose acetate, comprises printing on sheets of a foil of the material, the sheets being fed into a printing press together with sheets of supporting material, such as paper or thin cardboard, or the same material as the sheet to be printed. The sheets may be connected together by pasting or gluing at one or more edges, or a large sheet may be folded in two so that half of it forms-the supporting sheet. The sheets may be severed from webs fed together to a common severing-device. The supporting sheet has the effect of neutralising static electricity generated in the foils. The invention is particularly applicable to the production of booklets comprising transparent sheets each containing part of a total pictorial representation, each sheet having a non- transparent partial representation, and the sheets being viewed in succession in space or time. Specification 457,696, [Group XV], is referred to.

Title: Improvements in the manufacture of cellulose esters
Inventor: PARSONS DAVID GORDON
IPC: C08B3/24
Filed: 1956-03-01
Abstract: Organic acid esters of cellulose having a degree of substitution below 2.25 are prepared by hydrolysing a cellulose ester of the same organic acid or acids having a degree of substitution above 2.25 using as hydrolysing catalyst an acid having a degree of ionisation of at least 0.1 measured in normal aqueous solution at 18 DEG  C., the catalyst being present in amount of at least 0.5 gram mol. per litre of solution.  The method is particularly suitable for the preparation of lowly substituted cellulose esters of fatty acids containing up to 4 carbon atoms. The starting material, i.e. the ester having a degree of substitution above 2.25, prepared, for example, by treating cellulose with an acid anhydride using an acid catalyst, may be precipitated and washed before being redissolved for hydrolysis, but it is preferable to carry out the hydrolysis without any such intermediate precipitation.  Sulphuric acid, perchloric acid, nitric acid and hydrochloric acid are suitable hydrolysing catalysts, and the hydrolysis is preferably carried out at 15-50 DEG C.  When the hydrolysis has proceeded as far as is desired the catalyst may be neutralized with a suitable compound of an alkali metal, an alkaline earth metal, magnesium, zinc or aluminium, e.g. an alkaline-earth metal acetate or magnesium acetate.  The ester may be precipitated in the usual way, i.e. by running into water or dilute acetic acid and stirring, but the solution is preferably extruded in the form of filaments into the liquid precipitant, e.g. water or aqueous acetic acid of concentration below 20 per cent.  The spaghetti-like product may then be cut into short lengths and broken down or ground.  The precipitated ester may be stabilized by incorporating in it an acid-neutralizing salt, e.g. an alkali or alkaline earth metal bicarbonate, or a buffer mixture of salts such as a mixture of sodium phosphates giving a pH of 6-7.5.  The esters obtained are suitable for the production by wet or dry spinning of textile articles having a considerable affinity for substantive dyes. Cellulose acetate of acetyl value below 47.5 per cent obtained as described above, may be spun from solution in aqueous acetone, for example, into water or a dilute solution of acetone preferably maintained at 10-25 DEG  C.  The filaments obtained may be softened by hot water and stretched by passing through a bath of hot water. They may be saponified with dilute caustic alkali, preferably containing an alkali metal acetate, to give products of still lower acyl value or substantially unsubstituted cellulose.  Specifications 782,903 and 790,039 are referred to.

Title: Improvements in or relating to the method of manufacturing suspension wire wheels
IPC: B60B31/00
Filed: 1928-03-02
Abstract: 286,310. Booth, W. N. March 3, 1927, [Convention date]. Wheels.-Relates to a method of building wire wheels in which accurately-shouldered spokes are assembled in the hub and rim members which are then temporarily distorted whilst the spokes are fixed in position, the latter being automatically tensioned on release of the hub-and-rim stressing-means. The apparatus shown is for so constructing a wheel comprising a hub 10 adapted to be detachably secured to a permanent hub 9, a front set of radial spokes 3, a rear set of crossed tangent spokes 4, and a felloe 6 having struckup tongues 7 which-form abutments for clamps 8 securing a detachable rim 5. The inner ends of the spokes are formed with spherical heads 27 to engage corresponding seatings in the flanges 31, 30 of the hub 9, the outer ends having shoulders 28 and tenons 29 to engage the rim 6. Figs. 4 and 6 show the method of assembling the inner set of spokes 4. The hub is positioned by the boss 40 and pins 36 on a jig 33, the rim 6 being centered by the rim of the jig and a pin 34 engaging the valve-hole 35 in the wheel-rim. The spokes are then assembled from inside the hub and a chuck 37, with plungers 44 adapted to be actuated by an adjustable conical plug 45, is fitted in the hub. The pressure of the plungers 44 distorts the hub and rim, and relieves the spokes of tension. The partiallybuilt wheel is then transferred to the apparatus shown in Fig. 6 in which the spokes are successively engaged in gripping-jaws 53 whilst a punch 54 rivets over the spoke-tenons. The outer set of spokes is then assembled and secured in a similar manner. Fig. 13 shows a device for truing up the hub 9 at the parts which coact with seatings on the permanent hub. The wheel is clamped to a jig 76 fitted with a bush 80<1> to receive the spindle 77 of a rotary tool-holder 80. Cutters 81, 82, 83 remove any irregularities on the bearing surfaces of the hub.

Abstract: 1,096,803. Transmission system. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 17, 1966 [Feb. 26, 1965], No. 6935/66. Heading G4H. A transmission system comprising a transmitter and a receiver includes means in the transmitter for producing a reference signal, representing the output from the receiver, for comparison with an unknown analogue signal, the result of the comparison being sampled and a pulse of fixed amplitude and duration being transmitted when the input signal exceeds the reference signal. In one embodiment (Fig. 2) the means for generating the reference signal comprises four triggers R 1 -R 4  connected as a shift register, a pulse from the comparator C to the receiver when the input signal exceeds the reference signal setting the first trigger R 1 during the first time interval so that a reference signal e 1  (Fig. 1d, not shown) is fed to the comparator. During the three succeeding time intervals triggers R 2 -R 4  are successively set. The triggers R 1 -R 4  when set apply differing voltages to analogue adders B 1 , B 2 , B 3  and if during any time interval the input signal exceeds the reference signal, trigger R 1  is reset. Consequently each pulse of one time interval transmitted to the receiver represents an analogue signal lasting from time intervals having values e 1 , e 2 , e 3 , e 4  at the end of each time interval (Fig. 1a not shown). In a second embodiment (Fig. 3, not shown) the pulse from the comparator is transmitted when trigger R 4  is set, i.e. after a delay of three time intervals.

The drain conduit is provided with an enlarged portion 33 variation of the size of which will vary the rate at which pressure builds up therein and thus varies the periods at which a siphon is formed which returns liquid from a sump 25 in the evaporator 22 to the secondary generator 36. The latter is connected to the main generator by a U-tube 37 and may be provided with a dome into which the drain pipe 34 enters. The drain back of liquid takes place during the early part of the heating cycle as when the liquid in the generator 36 falls below the end of pipe 34 the pressure equalizes at both ends of pipe 34 and the drain stops. During the generating step liquid and gas circulate through the condenser receiver 28 and its cooling coils 30. When the absorption step begins the pressure in the condenser drives liquid up to the evaporator. Vapour from the generator 5 passes through a pipe 10 to a liquid trap 14, a rectifier 16 and thence through the evaporator 22 to the condenser.
