Abstract: 660,571. Mechanically treating paper pulp. CONSOLIDATED MACHINE TOOL CORPORATION. Aug. 7, 1947 [June 6, 1946; June 6, 1946; Oct. 25, 1946], Nos. 21555/47, 21556/47 and 21557/47. Class 96. A machine for treating paper pulp and carrying out the process of Specification 660,570 has two opposed rough surfaces between which the pulp is fed, one surface being moved, e.g. cyclically, towards the other to compress the pulp and, at the same time, the surfaces are moved relatively in different directions perpendicular to the direction of pressure to roll the pulp. They may be moved or gyrated in parallel planes so that all points on one surface move in equal circles relative to the other. A machine for treating one batch of pulp at a time, Fig. 1, has opposed parallel surfaces 23 and 20 and the latter is gyrated and moved to and from the former by being fixed to a plunger 7 sliding in an eccentric bore through a rotatable shaft 2 the plunger 7 being connected through Cardan joints 8 and 9 and a non-rotating rod 12 with a piston 17 reciprocating in a cylinder 13 to the opposite ends of which hydraulic pressure is applied and released cyclically through pipes 15 and 16 connected with an automatically operated valve. The lower surface 23 may be reciprocated similarly, but is usually kept stationary during operation of the machine and only lowered to permit charging and discharging of pulp. In a machine for continuous operation pulp is fed in through a central opening in one surface and discharged at its edges. The surfaces may have symmetrically arranged pyramidal, tetrahedral, or conical teeth and the angle between opposed faces of adjacent pyramidal teeth may vary between 40 degrees and 100 degrees. Machines may have stacked multiple pairs of surfaces, e.g. a plate with working surfaces on each of its faces could be interposed between two surfaces.

Title: Coating of articles
IPC: B05B12/12
Filed: 1972-05-10
Abstract: 1390441 Spray coating apparatus RANSBURG CORP 10 May 1972 [10 May 1971] 21810/72 Heading B2L Apparatus for electrostatically spray coating articles 13 comprises means for moving spray guns 17, 19 in opposite vertical directions and guns 16, 18 in opposite horizontal directions relative to the article to be coated so that the peripheral areas are coated. The articles to be coated are supported on hangers 12 and are carried on an overhead monorail 11 past an array of photocells 58 which determine the dimensions of the article as it passes. A light beam falling on photocell 72 is broken by the hanger 12 and this allows the information to be passed -to the control system. The articles then pass to a coating zone 14 comprising an assembly 27 which supports the spray guns. As the article approaches the assembly, hanger 12 strikes an arm 51 of potentiometer 52 and this causes a prime mover in the form of a ram 45 to move the assembly 27 along at the same speed as the hanger. Clamps 56, 57 hold the hanger at the bottom to prevent it from moving relative to the assembly 27. The information received from the photocell array 58 causes stepping motors such as 24 25 on the gun mountings to position the guns accurately adjacent the areas to be sprayed. The carriages 32, 33, 34 on which the guns are mounted are moved along the main members of the assembly 27 by chain drives 35, 41 such that the guns on the horizontal arms are connected to one chain and hence move in opposite directions and similarly the guns on the vertical arms move in opposite directions. The chains are both driven from the same prime mover and suitable gearing takes account of the sizes to be dealt with. When the coating operation is completed limit switches release the clamps 56, 57 and return the assembly 27 to its starting position. The assembly 27 is mounted on a carriage 93 so that it can be moved transversely of the direction of the conveyor to allow for different thicknesses of articles.

Abstract: 888,306. Transistor switching circuits. SIEMENS-SCHUCKERTWERKE A.G. June 26, 1959 [June 30, 1958], No. 22019/59. Class 40(6). A switching circuit comprises an input transistor having its emitter-collector path connected in parallel with the collector-base path of the succeeding transistor, the parallel portion of the succeeding transistor circuit including a resistor arranged to carry the collector current of that transistor and less in value than the collector-emitter load resistor. In the Figure, an. input is applied at 7a and 8a or 9a and 8a to render a normally non-conducting transistor 6a conducting. This causes the succeeding transistor 3a to conduct, the collector currents of both transistors passing through the load 5. In order to ensure that the collector-base circuit of the succeeding transistor falls to a low value, less than that of the emitter collector voltage of transistor 6a, a resistor 4 is included in the collector path of transistor 3a. Transistors 6a and 3a may be of opposite conductivity type (Fig. 3, not shown) and transistor 3a may be replaced by two transistors connected in parallel with separate or a single collector resistor and with emitter resistors to equalize the transistor currents (Fig. 4, not shown). In addition, rectifiers may be connected between terminals 7a and 8a, and 7a and 9a in order to control the reverse voltage applied to the emitter junctions of transistors 7 and 3a.

Title: Improvements in or relating to x-ray detectable thread and surgical dressings
Inventor: PRESTON JOHN MASSEY
IPC: A61K49/04
Filed: 1953-08-12
Abstract: Viscose yarn has incorporated therein at least 15 per cent by weight of an X-ray detectable material such as barium sulphate. The yarn may also contain a coloured pigment, for identification purposes.  One or more of the yarns may be woven into surgical dressings.  The barium sulphate, or the like, is added to the spinning solution as a dry powder having a particle size of less than 4 microns after the main filtration but before the solution is filtered in the spinning machine, the spinning machine filter being wadding weighing 300 gms./square metre.  The solution is spun from a spinneret having holes of at least 100 microns, preferably 120 microns, to a final yarn denier of at least 3000. In an example, viscose containing 8 per cent cellulose and 6.5 per cent alkali was filtered twice through wadding and to the filtrate was added 8 per cent by weight of dry barium sulphate of particle size 1 micron.  The mixture was agitated for 30 mins. with a high-speed stirrer and then de-aerated by standing for 6 hrs. under a reduced pressure of 2 lb. per sq. in. absolute.  The viscose was passed through cotton wadding weighing 300 gms. per sq. metre and spun form a spinneret having 720 holes of 120 micron diameter into a bath containing 9 per cent sulphuric acid, 4 per cent magnesium sulphate, 1 per cent zinc sulphate and 18 per cent sodium sulphate.  The spinning speed was 65 metres/minute and the stretch 30 per cent.  After bleaching, dyeing and conditioning the final denier was 10,000 and the barium sulphate content 48 per cent. In a second example, 10 per cent of the filtered viscose solution was mixed with 42 per cent by weight of the dry barium sulphate by means of a paddle and circulation through a pipe containing a reed vibrating at supersonic frequency.  The solution was then centrifuged, added to the remaining 90 per cent of the filtered viscose solution together with 0.01 per cent of the total weight of iso-octyl alcohol to prevent formation of stable froth, the whole mixed and de-aerated under reduced pressure.  The mixture was spun through a spinneret having 480 holes of 120 micron diameter to give a thread of 7000 denier containing 28 per cent of barium sulphate, two of these threads after desulphurizing and drying being twisted together to form the final detector thread.  In a third example, 0.1 per cent of a 20 per cent aqueous suspension of a blue insoluble pigment of 1 micron particle size was added to the viscose for identification purposes.
