Title: Improvements in or relating to the making of sheet material from fibres produced from hides or skins
IPC: C08L89/06
Filed: 1930-07-29
Abstract: 360,017. Fibrous sheet materials. SOC. INVENZIONI BREVETTI ANON.- TORINO, 8, Corso Vittorio Emanuele, Turin, Italy.-(Assignees of Mackay, A. ; Asbury Park, New Jersey, U.S.A.) July 29, 1930, No. 22847. Convention date, Nov. 29, 1929. [Class 140.] In a process for making sheet material from. fibres obtained from hides or leather by depositing the fibres from a slurry or suspension thereof upon a reticulated support, a portion of the desired length of a formed sheet is wound on a reel, the formation of a second sheet is commenced and simultaneously the two sheets are superposed by connecting the rear end of the first sheet with the front end of the second sheet which is being formed, a layer of adhesive being interposed between the sheets. The material treated, which may be tanned or untanned hides or leather or scraps or cuttings therefrom, is first disintegrated and washed, and a slurry of the fibres in water is made. In the case of tanned fibres, the acidity of the fibres is neutralized, for example by the addition of an alkali such as sodium carbonate, and if the fibres are mineral tanned, by the addition of Rochelle salts to the slurry. A tanning solution such as sumach or quebracho, or mineral tanning agents or synthetic tannins, is then added, and an emulsifiable oil such as sulphonated cod oil or colloidal neat'sfoot oil. The slurry is then preferably neutralized with a mild alkali such as sodium carbonate. A binding material is then added, preferably a waterproof binder ; rubber, guttapercha, or balata latex may be used, or a synthetic latex. After complete incorporation of the binder, the slurry is treated with alum, tannic acid, an organic acid or other catalyst to precipitate the binder on the fibres. The slurry is then fed on to a travelling reticulated conveyer. 1, for example, of wire gauze, which passes over a roll 2, at which point the slurry is subjected to suction to extract the liquid. The forward end of the sheet is taken off the conveyer by a felt 3 and carried beneath a presser roll 4, and passes to a reel 5, which may be heated. After a length of material has been wound on the reel, the latter is shifted to the right, and the sheet cut. The cut end of the sheet is then superposed on the leading end of the new sheet being formed, the two sheets being passed together under the roll 4 and wound upon a second reel 5. Adhesive such as casein, latex, glue, rubber cement, or oil, is sprayed between the two sheets by means of a sprayer 8. The compound material is afterwards passed through pressure rollers and around drying rollers. The preliminary treatment of the fibres may be varied from that described; colouring material may be added to the slurry.

Title: Cathode-ray display device for recurring pulses
IPC: G01R13/24
Filed: 1956-07-24
Abstract: 833,645. Measuring time intervals. REALISATIONS ULTRASONIQUES. July 24, 1956 [July 29, 1955], No. 22893/56. Class 37. [Also in Group XL (c)] The time interval t between adjacent pulses of a train of signal pulses initiated by a trigger pulse is determined by applying the trigger pulse to excite a calibrated variably-turned circuit whose damped sinusoidal output is applied in phase-quadrature to the X and Y plates of a cathode-ray tube to produce a spiral timebase, Fig. 2, which is intensity modulated by the signal pulses and adjusting the recurrence period to of the tuned circuit to equal the recurrence period t of the signal pulses, such condition being indicated by the radial alignment of the signal pulse images 18 ... 23 as shown in Fig. 2; the value of t is then given by the setting of the tuning control. In a modification the sinusoidal output from the tuned circuit is applied to the X-plates and a sawtooth sweep voltage initiated by the trigger pulse is applied to the Y-plates to produce a trace as shown in Fig. 3; in this case the correct tuning setting is obtained when the signal pulse images 18<SP>1</SP> ... 23<SP>1</SP> are aligned vertically as shown. The invention is described as applied to a pulse-echo ultrasonic system for determining the thickness of a workpiece (see Group XL (c)) in which each trigger pulse initiates a transmitted ultrasonic pulse, the signal pulses being derived from the echo pulses produced by multiple reflection between the front and back surfaces of the workpiece.

IPC: C10K1/04
Filed: 1929-07-25
Abstract: 317,780. Gewerkschaft M. Stinnes. Aug. 22, 1928, [Convention date]. Washing processes; materials for purifying.- In freeing coal gas from naphthalene after the usual washing with benzene by treatment with an oil solvent for naphthalene and then cooling, the gas is finally washed with an oil of high boiling point free from naphthalene in order to obtain remaining benzene and other vapours. The oil after absorption of such vapours is used in the earlier stage as a solvent for naphthalene, e.g. mixed with 20 per cent of an oil of lower boiling point and under 5 atmospheres of pressure. This oil is freed from naphthalene by passing through it a gas preferably free from oxygen, e.g. furnace gases at a higher temperature. Specifications 305,545 and 311,326 are referred to.

Title: Improvements in or relating to cathode ray tubes
Inventor: ALLARD LAWRENCE SIDNEY
IPC: H01J29/18
Filed: 1955-08-09
Abstract: 811,724. Cathode ray tubes; electroluminescence. GENERAL ELECTRIC CO. Ltd. July 31, 1956 [Aug. 9, 1955], No. 22958/55. Class 39(1). The phosphor screen 7 of a cathode-ray tube is sandwiched between two conductive layers 6, 8 to which different potentials can be applied. It is found that when the potential of layer 6 is more positive or more negative than that of layer 8 the cathodo-luminescent effect is enhanced or diminished respectively. As shown the end-wall 4 of the tube is coated with a layer 6 of stannous oxide, by decomposition of stannic chloride in the presence of water vapour at 550‹C. The phosphor layer 7 of silver (0À01-0À1 per cent.) -activated zinc and zinc-cadmium sulphide is then deposited to a thickness of 100 microns and finally a 0À1 micron layer 8 of aluminium. Leads 10, 11 are provided by silvering. When the layer 8 and final anode 13 are at 3000 volts and layer 6 at 6000 volts the intensity is ten times that when both layers 6, 8 are at 3000 volts. A reverse potential of 2000 volts suppressed the fluorescence entirely. A layer of secondaryelectron-emissive material such as magnesium oxide, 0À01-0À1 microns thick may be interposed between layers 7 and 8. For television reception the video signals may be applied between layers 6 and 8 to modulate the screen intensity. Forcolour television layer 6 may be in the form of three interleaved sets of strips, each strip covering a phosphor of different colour. Positive voltages applied to the strips in sequence to bring into action the appropriate colour phosphor, for example in frame-sequential operation. Specification 727,140 is referred to.

Title: Improvements in or relating to type printing apparatus
IPC: H04L21/00
Filed: 1958-07-17
Abstract: 874,125. Selective printing. HANDLEY, J. July 10, 1959 [July 17, 1958], No. 23029/58. Class 100(4) A printing machine comprises a printing head 1, an arm 5 resiliently connected to the head and moved continuously so as to urge the head 1 in a letter-space direction during printing of a line of print and means for preventing movement of the printing head in the said letter-space direction during moment of impression. As described the arm 5 is moved hydraulically and when the first signal, from say a calculating machine, is received, pumping is effected until after a carriage-return signal is received. During the moments of impression the head is held stationary by a pawl 7 engaging a rack 8 although the arm 5 continues to move; this being allowed by a resilient connection 33, 34, 25. When a letter-space signal is received the printing head advances because the pawl 7 is lifted from the rack 8 by a crank 12, Fig. 3, actuated by a piston 13 either mechanically or hydraulically operated. Piston 13 returns to the right between letterspace signals allowing the pawl 7 to re-engage the rack 8. Contacts 37 prevent any character signals effecting the operation of the apparatus until the pawl 7 re-engages the rack in response to a letter-feed signal. Tabulation. In response to a tabulation signal the pawl 7 is lifted clear of the rack 8 in a similar manner but also held clear by a lever 15 which is moved to the left by a piston 13 operated also in response to the signal. The lever 15 holds the pawl 7 clear by means of the crank 12 and notch 18 thereon until the tabulation stop 20 is engaged. The lever 21 has a bevelled lower end which engages the step 20 so that engagement pivots lever 21 and lever 15 is unlatched and pawl 7 re-engages the rack 8. Carriage-return arrangements. When a carriage-return signal is received both pistons 13 and 16 are operated in a manner similar to that of a tabulation operation. The tabulation stops 20 are all bevelled on the sides engaged by the lever 21 in a carriage-return movement so that the lever 21 is deflected in an anti-clockwise direction clear of the tongue 36. The carriage-return signal also operates the hydraulic mechanism and controls valves to allow the fluid to escape and the arm 5 is moved to the left by a spring. Specifications 798,093 and 849,430 are referred to.
