Patent GB-840907-A (GB)
Title: Improvements in or relating to quick-acting cut-out devices
Inventor: DELLOUE GERARD
IPC: H05G1/70
Filed: 1958-03-13
Abstract: 840,907. Protective cut-out arrangements. SOC. DE CONSTRUCTION D'APPAREILS BARDON. March 13, 1958 [April 26, 1957], No. 8091/58. Class 38 (5). [Also in Group XL (c)] A solenoid R3 is energized to trip open contacts C when the current I in a D.C. circuit exceeds a predetermined value and causes a transistor N1 to become conductive. In Fig. 3 a rectifier G is protected by the tripping of the contacts C in the A.C. supply to the rectifier when the voltage produced by the D.C. load current across a shunt R1 exceeds a value determined by an opposing bias derived from a transformer T, rectifiers E1 and a resistor R2, the base of the transistor N1 being biased by the difference between these voltages. In Fig. 4 the bias normally applied to the base of a transistor N2 is such that this transistor conducts and causes the potential at a terminal 5 of a resistor R4 to bias the transistor N1 to its non-conducting state. When the current through the shunt R1 exceeds a predetermined value, the voltage drop across the shunt tends to make the base b 2  of transistor N2 positive with respect to the emitter e 2  and the resulting reduction in the emitter-collector current reduces the potential at terminal 5. This renders the base b 1  of transistor N1 negative with respect to the emitter e 1  so that current starts to flow in the emitter-collector circuit and the resulting change in potential at a terminal 8 of the resistor R7 makes the base b 2  of the transistor N2 more positive, so that an abrupt change to the state in which the transistor N2 is non-conducting and the transistor N1 is conducting occurs and the solenoid R3 is fully energized to trip open the contacts C.

Filed: 1940-05-08
Abstract: 541,049. Toughening sheet glass. B.I.G. SECURITIES, Ltd. (Gajoti, R.). May 8, 1940, No. 8316. [Class 56] Relates to the method of hardening a glass sheet in which the hot plastic glass is chilled by means of air jets directed normally on to its surface. According to the invention, some of the jets are supplied with low pressure air and others with highpressure air, both the high and the low pressure air being applied simultaneously. The air jets are moved in an approximately circular path during the cooling-operation. The glass sheets 15, suspended from an overhead rail 13, pass through a furnace 11 and are chilled in the cooling-apparatus. This consists of two air boxes 17, secured together by a yoke 18 which is connected by means of a rod 19 to a crank pin 20 rotated by a motor 21. The air boxes are kept vertical by means of springs 22 secured to a frame 23. Air at relatively low pressure is supplied to the air boxes through conduits 24, and emerges from rows of holes 29, Fig. 2, in the inwardly facing surfaces cf the boxes. The high pressure air is supplied to pipes 26, Fig. 2, attached to the inward surfaces of the boxes and perforated with holes 30. In a modified construction, the inward surfaces of the air boxes are corrugated, holes for the emission of high- or low-pressure air being formed in the ridges while holes for the emission of air at the other pressure are formed in the furrows of the corrugations. Alternatively, pipes similar to the pipes 26 are accommodated in the furrows. The rotation of the crank pin 20 causes the air boxes to move in an approximately circular path.
Patent GB-402054-A (GB)
Title: Improvements in or relating to the production of dispersions of colouring matters
IPC: D06P1/16
Filed: 1932-03-21
Abstract: Dyes which exist in stable and metastable physical forms, and which normally yield dispersions unstable to hot soap solution, are converted into their stable forms by the action of heat and then dispersed in an aqueous medium by milling or grinding, whereby dispersions stable to hot soap solution, and suitable for dyeing organic derivatives of cellulose, are obtained.  The conversion of the metastable into the stable form may be effected by the heating action of steam, hot air, or hot water; the metastable form may be heated in aqueous dispersion, preferably in the absence of powerful dispersing agents or protective substances and if desired in the presence of an alkali and (or) a substance having a slight solvent action on the dye.  The stable dye thus obtained, after filtration if desired, is milled or ground in an aqueous medium in the presence or absence of protective colloids. Concentrated or dilute dispersions may be prepared directly, or dilute dispersions may be prepared and then concentrated, or concentrated dispersions may be prepared and then diluted, with or without addition of protective colloids or dispersing agents as described in Specifications 219,349, 224,925, 242,393, 273,819, 273,820, 322,737, and 323,788, [all in Class 15 (iii), Dyeing, Processes &c. for], and with or without auxiliary solvents as described in Specifications 242,711 and 269,960, [both in Class 15 (ii), Dyeing, Processes &c. for].

Patent GB-231860-A (GB)
Title: Improvements in apparatus for sheet-fastening machines for applying adhesive to the sheets
IPC: B05C1/02
Filed: 1925-03-30
Abstract: 231,860. Stõubli & Co., Geb. April 4, 1924, [Convention date]. Coating-machines. - In sheetfastening machines of the kind wherein gum is applied to the sheets by gummers which receive gum from a roller rotating in a gum tank the gummers execute an approximately circular rocking motion, during which they rock towards the roller to take up ,gum, and, rocking back, deliver the gum to the sheet, after which they rock rapidly out of the path of the sheet-carrying table. Vertical arms 41, 42, Fig. 1, on a stationary shaft 40 support the gum tank 43 and provide bearings for a rotatable ehaft 44, to which are secured two levers 45, 46 carrying a bar 47 supporting gummers or dabbers 48 with gumcarrying edges 90. The circular rocking motion is given to the dabbers by rocking the shaft 44 by means of an arm 53 connected by a link 52 to a lever 49, which is pivoted on a shaft 15 and carries a roller 50 in contact with a cam 51 fixed on the shaft 2. The paper-table 13 is carried on an arm 14 mounted on the shaft 15 pivoted between the frame ends .of the machine. Inward and outward rocking motion is imparted to the paper-table 13 by a rocking arm 25, which is secured to the shaft 15 and carries a roller 26 working in a cam groove 27 in a cam 28 fixed on the shaft 2. In operating the machine, a sheet 89 is placed on the .auxiliary table 30, Fig. 2, and a treadle is actuated, whereupon the sheet is fed to the table 13 and beneath the guide 64, which is then lifted to enable the table to move inwardly to carry the edge. of the sheet against the gum carriers 90 where a strip of gum is applied. Hereupon the cam 51 becomes operative and rocks the gummers inwardly and upwardly to clear the inwardly moving table carrying the gummed sheet, allowing the sheet to be applied when the table reaches its highest position, as shown in Fig. 16. After the stitching is performed the cam disc 28 operates to swing the table 13 outwardlv in readiness to receive a fresh sheet from the slide 34, which has moved back to its original position. The gum roller 55 is rotated intermittently in the gum tank by a pawl-and-ratchet mechanism which is linked to the rocking lever 45 supporting the dabber bar 47. The operation of the gumming-device is independently controlled by means of a treadle 66 situated in front of the treadle controlling the driving-mechanism, and connected by a horizontal rod 65 and vertical link 68 to a hook 70 which is pivoted upon the shaft 40 and co-operates with a pin 92 fixed to the lever 45.

Title: Process of making hydrophilic carbon black
IPC: C09C1/56
Filed: 1948-03-23
Abstract: In compounding natural or synthetic rubber, e.g butadiene-styrene copolymers, a 5-10 per cent aqueous suspension of carbon black, which has been rendered hydrophilic by treatment with an aqueous solution of a hypochlorite of an alkali or alkaline earth metal, is added to produce a stable dispersion, free from dispersing agent, without coagulation and the copolymer is precipitated with 10-35 per cent carbon black dispersed therein by acidifying the dispersion.ALSO:Hydrophilic carbon black is prepared by exothermally reacting furnace, thermatomic, or acetylene black with an aqueous solution of a hypochlorite of an alkali or alkaline earth element, e.g. sodium or potassium.  The carbon black may be treated directly with aqueous hypochlorite, or suspended in caustic soda solution through which chlorine is passed, or suspended in an aqueous sodium chloride solution which is electrolyzed.  For example carbon black is treated with 10 per cent sodium hypochlorite solution at 35 DEG C and the sludge with pH8-9 is acidified to pH2 by hydrochloric acid.  The sodium chloride and excess hydrochloric acid are washed out and the carbon black is separated from the sludge by centrifuging, filtering and partial air drying at below 100 DEG C.  The dry product still contains 5 per cent water and may be readily dispersed in water after the addition of a few drops of ammonia.  A water paste of the carbon black containing 30-60 per cent water may be used as a lubricant in place of graphite paste.
