Patent GB-769523-A (GB)
Title: Paper planographic plate and process of manufacture
IPC: B41N1/14
Filed: 1954-04-21
Abstract: 769,523. Planographic printing surfaces. TICKNER, A. (Columbia Ribbon & Carbon Manufacturing Co., Inc.). April 21, 1954, No. 11585/54. Class 100(2) A coatedpaper planographic printing plate is made by coating one surface of a paper sheet with a planographic surfacing material having a curl producing tendency, coating the other surface of the sheet with an aqueous dispersion of a coagulable colloidal material, and treating the colloidal with a coagulant solution whose concentration is adjusted to cause a counteractive curl substantially equal in effect to the curl produced by the curl-producing material, whereby a substantially flat sheet is produced. In an example the printing or primary surface of the sheet is treated with a slurry containing 100 parts by weight of an aqueous solution of sodium carboxymethyl cellulose, 20 parts by weight of china clay, and 3 parts by weight of glycerine, and after drying it is treated with a coagulating salt, e.g. an aqueous solution including 3 per cent copper sulphate, 1 per cent aluminium sulphate, ¢ per cent ferric chloride, and per cent chromium trioxide. For testing the rear or secondary surface of the sheet an aqueous slurry of casein is prepared (including about 5 per cent casein) which is coated on the sheet and dried. The secondary surface is then treated with a coagulant solution, e.g. of alum, the concentration of which is obtained by experiment so that the curl-producing effect of the primary surface coating is neutralized. The coagulant applications to both surfaces of the sheet are preferably made at the same location on the machine, and both are dried simultaneously. If a water-barrier coating is employed the barrier coating may be applied to the secondary surface of the sheet and serves as the coagulable coating. Other coagulable agents may be used such as formaldehyde or glyoxal which have a coagulating reaction on certain colloidal materials. Specification 769,520 is referred to.

Title: Improved means for synchronizing clocks
IPC: G04R20/00
Filed: 1926-05-04
Abstract: 252,150. Junghans Akt.-Ges., Geb. May 12, 1925, [Convention date]. Controlling clocks. - In an electric clock which is connected periodically by waves from a distant wireless station, the synchronizing mechanism is arranged to be actuated only by the time signal from the particular station and not by ordinary messages on the same or other wave-length. The minute hand has rigid with it a heart-shaped cam c coacting with a roller b<3> on a pivoted arm b having a segmental rack extension b<1> which co-operates with the gearing b<2> of a fly regulator. A rod e is pivoted to the arm b and to a detent member f which is rotated counter-clockwise by a differential a driven from the mainspring when a. member g is lowered, this member carrying the armature of a magnet d which is energized at synchronizing. Thus, when the latter occurs, the rod e is drawn down and the roller b<3> positioned in the cam c to set the minute hand to its correct position. The fly regulator retards the upward stroke of the rod e to ensure that the detent member f shall not complete its rotation before the member g has risen again to lock it. A receiving magnet 1 has an armature rigid with a spring-controlled lever 3 which carries a pin engaging the spring 4 of a balance 2 which oscillates once each second. At the particular wave-length ordinary messages will energize the magnet 1 at irregular intervals and through the lever 3 and its pin thus will clamp the oscillations of the balance, but when the time signal is received at one-second intervals the pin on the lever 3 will move in consonance with the balance, the oscillations of which are thereby amplified to enable a pin 19 on the balance to function correctly as set out below. The lever 3 is connected by a link 6 and pawl 7 to a governor 8 which provides for rapid acceleration of the balance when the time signal is received. Rigid with the minute hand is an arm 9 having a pin which moves a twelve-toothed wheel 10 one tooth per hour. This wheel carries a pin 11 so positioned that four minutes before the time signal commences a lever 12 is rocked to release an arm 14 rigid with a shaft 15 and an arm 13, which latter thereby falls to close contacts 16 in the circuit of the magnet 1. At the same time an arm 17 rigid with the shaft 15 is moved to place a contact arm 18 which it carries in the path of the pin 19 so that the latter in oscillating fully at the time signal moves the arm 18 to make contact at 18<a> thereby completing the circuit of the magnet d. When the roller b<3> is lowered an arm b<4> rigid with the arm b is moved over to return the arms 13, 17 which are then latched up by the return of the lever 12 under the arm 14. A safety device is provided for returning the arms 13, 17 if the arm b<4> fails to do so.

Title: Improvements in or relating to a method for insolubilising artificial filaments obtained by the spinning of solutions of proteins
Inventor: MCGILLIVRAY ROY
IPC: D01F4/00
Filed: 1954-04-23
Abstract: Artificial filaments, obtained by spinning a solution of protein to form a bundle of protein filaments and hardening the filaments by treating them with a hardening agent, are insolubilized by impregnating the bundle of hardened filaments with an aqueous solution of formaldehyde having a pH greater than 6, and heating the bundle to such a temperature and for such a period of time that the filaments do not dissolve within 90 minutes in an aqueous solution of 0.1 per cent sulphuric acid and 0.25 per cent sodium sulphate at 97 DEG  C.  Preferably, after the impregnation with the aqueous formaldehyde solution the filaments are stretched, e.g. 200 per cent, and are held in the stretched condition while undergoing drying at least long enough that they no longer tend to shrink, prior to heating them to insolubilize them.  The drying of the filaments, whether or not in the stretched condition, may be done at 15-160 DEG C. and the insolubilization at 120-180 DEG  C.  The pH of the formaldehyde solution may be 6.5-11 and preferably 6.5-7.5 or 9.5-11 and its concentration may be 10-37 grams formaldehyde per 100 c.c. of solution.  The pH of the formaldehyde solution may be adjusted between 6.5 and 7.5 by means of sodium borate, aluminate, stannate, tungstate or hydroxide, ammonium hydroxide, potassium chromate or pyridine, or between 9.5 and 11 by means of sodium stannate, aluminate or hydroxide.  The hardening agent is preferably an aqueous solution of formaldehyde which may also contain a high concentration of sodium chloride or sulphate and have a pH of about 4.5.  The hardened filaments may be treated while still wet or after having been dried.  Preferably, if the filaments are to be stretched while wet, the formaldehyde hardening should be effected in 10-15 minutes at 50 DEG  C.  In an example, filaments produced by spinning a matured alkaline solution of peanut globulin in an aqueous acid saline coagulating bath and relaxed in a concentrated aqueous saline bath are hardened for 7 minutes at 50 DEG  C. in a bath consisting of 20 per cent sodium sulphate, 2.5 sodium chloride and 1.5 formaldehyde at pH 5, mangled, washed in water and dried at 80 DEG  C.  The filaments are then impregnated with 10 per cent formaldehyde solution adjusted to pH 7.5 with sodium hydroxide, mangled, dried at 80 DEG C. and heat treated for 30 minutes at 160 DEG  C.  Specifications 513,910, 533,952, 596,536, 597,497, [all in Group IV], 605,830, 623,460, 642,359, 654,513 and 708,057 are referred to.

Abstract: 875,439. Circumferential flow pumps. NORTHEY ROTARY COMPRESSORS Ltd. April 4, 1960 [April 13, 1959], No. 11794/60. Class 110 (1). A pump of the ventural type i.e. one in which the rotor rotates in a casing with inlet and outlet passages leading to the interior of the casing and forming with a space around part of the periphery of the rotor a convergent-divergent Venturi type of throat, has the inlet and outlet passages crossing one another in different planes and the smaller arc of the casing between these passages subtends at the centre of the rotor an angle not greater than a right angle. The pump comprises a two-part casing 10 enclosing a rotor 11. A part 12 of the casing between the inlet and outlet passages is cylindrical and subtends at the centre of the rotor 11 an angle of not more than 70 degrees. The rest of the space in the casing 10 forms with the rotor 11 an arcuate passageway 13 of convergent-divergent form which merges with the inlet and outlet passages 14, 15. The passages 14, 15 are in slightly different planes and one or both of them extends or extend slightly away from the plane of the rotor. For ease of manufacture, only one passage, normally the inlet passage, diverges from the plane of the rotor. In a modification, Fig. 3 (not shown), the inlet and outlet passages are substantially in line with one another. In another modification, Fig. 7 (not shown), two separate rotors are mounted upon a common driving shaft in a single casing. These rotors are of different diameters and widths. Interconnected valves are provided in the inlet and outlet passages so that one or the other of these impellers may be put into operation. The pump may be made with three or more rotors of graduated diameters and widths with corresponding passageway and valve arrangements. Specification 487,278 is referred to.

Abstract: 687,078. Statistical apparatus. POWERS-SAMAS. ACCOUNTING MACHINES, Ltd. April 27, 1951 [May 17, 1950], No. 12381/50. Class 106 (i). ' Record cards are fed from a magazine 1 to feed rollers 3, 4, and thence to a sensing chamber between perforated plates 5, 6, where the card is illuminated by light from the lamps 16. Light passing through perforations in the card is conveyed, for each data representing position in a column, along a separate plastic light guiding rod 18 to a separate photo-cell 19. The arrangement shown provides twelve photo-cells, one for each data position, in a column, as shown in Fig. 3, the eighty columns of a card being covered by the arrangement of ten light guiding rods, shown in Fig. 2, wherein each rod is of square section at the photo-cell end and is enlarged at the other end to span eight adjacent columns. The ten light guiding rods covering between them the eighty columns of a card are arranged with their square section ends grouped together opposite the appropriate photocell for the particular data bearing position in the column, as shown in Fig. 2. Resting on the upper surface of the perforated top-plate, Fig. 4, is a series of apertured shutters 9, one for each vertical column, the shutters each being selectively and independently movable by levers 11 to expose or obturate the apertures 7, 8 in their respective columns. Between the ends of the light guiding rods 18 and their respective photo-cells there is provided a shutter device mounted for reciprocation in timed relation with the movement of the card stop which locates the card in sensing position in the sensing chamber. The shutter device consists of two plates 20, 21, reciprocated in lengthwise direction by means of a cam 25 on the shaft 26 and lever 24, the arrangement being such that one plate moves in the opposite direction to the other so that their respective slots 22, 23, are brought into alignment to expose each photocell to the ends of the rods 18. In the obturating position, the plates are moved relatively to one another to obscure the slots 22, 23, and prevent the light from the ends of the rods 18 reaching the photo-cells 19. When a card is not in sensing position the shutter acts to obturate the photo-cells. In the machine shown, the output from the photo-cells is fed to separate amplifiers, the output of which is employed to control the action of card selecting pockets in a sorting-machine. Specifications 128,207, [Class 106 (i)], and 396,805 are referred to.

[Class 40 (iii).] A mirror wheel for television &c. comprising a rotatable body 1, as shown in the Figure, of metal, hard rubber, fibre composition &c., has the mirrors 6 directly attached to it by screws 8 normal to the mirrors. The screws 8 may be replaced by other positive fastenings such as nuts and bolts or rivets. The screws preferably pass through the centre of mass of the mirror ; when two screws are used, a line joining their axes cuts the radius vector to the centre of mass of the mirror, while when more than two screws are used, the centre of mass of the mirror lies within the polygon at whose vertices are the screws. Washers may be placed between the mirrors and the screws to distribute the pressure of the screws. The mirrors may extend axially beyond the body 1 which may have holes cut in it to reduce its mass, Fig. 2 (not shown) and may be tapered towards its periphery to reduce its inertia. To avoid distortion due to bending of the mirrors under the centrifugal forces due to rapid rotation, the mirrors may be slightly convex towards the outside of the drum when stationary, so that while rotating they may be straight.
