Title: A process for the manufacture of carbon refractory and insu ating materials
Inventor: GALY ANDRE
IPC: C04B35/532
Filed: 1959-07-21
Abstract: A porous carbon article, e.g. a brick, is produced by heating a paste comprising a mixture of a water-insoluble solid polysaccharide and an aqueous dispersion or solution of a gel-forming protein or carbohydrate to a temperature within the range of 1100 DEG -1200 DEG C. in a non-oxidizing atmosphere.  The polysaccharide may be in the form of wood chips, straw, or hard wheat flour paste.  The protein or carbohydrate may be in the form of molasses, manioc or arrow-root flour, starch, hemi-cellulose, carbohydrate gum, or animal glue.  The mixture may be produced by kneading the polysaccharide with the aqueous solution or dispersion at an elevated temperature.  The mixture may be lightly pressed at 100-200 gm/cm2 and then heated at the rate of 20-25 DEG C./hr.  Heating may be effected in a tunnel kiln with a covering of powdered coke or silica or in a rotary furnace. After cooling, the bricks may be reheated to 1700-1800 DEG C. under reduced pressure.  The carbon product may have a density of 0,25, a thermal conductivity of 0,3-0,5 kcal/m2/m/ DEG C./hr, a crushing strength of 10-12 kg/cm2, and an ash content of less than 0,2%.  Examples are given.

Inventor: HOSKING ALIDA HELENA
IPC: C08G64/16
Filed: 1958-08-05
Abstract: Branched-chain cross-linkable polycarbonates, useful in stoving lacquers, are made by reacting together a carbonating agent, a dihydroxy compound and a polyhydroxy compound having at least three hydroxyl groups, there being between the hydroxy groups in said hydroxy compounds at least three nuclear carbon atoms in an aromatic ring or in the absence of at least three such nuclear carbon atoms, at least four carbon atoms.  Specified carbonating agents are dialkyl and diaryl carbonates (possibly in the presence of a catalyst such as an alkyl titanate) and phosgene (in the presence of a hydrogen chloride acceptor such as pyridine). Specified dihyroxy compounds are diethylene glycol, pentane-1:5-diol, hexane -1:6-diol, the di(hydroxyethyl)ether of hydroquinone, the di(allyloxy hydroxypropyl) ether of hydroquinone, 4:41-dihydroxy diphenyl ether, 2:21-dihydroxy-1:11-dinaphtl yl, styrenated hydroquinone and dihydroxy diphenyl alkanes.  Specified polyhydroxy compound are the tri-(hydroxethyl) ethers of pyrogallol and phloroglycinol, the tri(allyloxy hydroxypropyl) ether of pyrogallol, the di (hydroxypropyl) ether of glycerol, and pyrogallol.  Cross-linking is effected by heating the polycarbonate, possibly with a curing agent such as a polyisocyanate, a dialkyl or diaryl carbonate, or aluminium or titanium alkoxides.  Stoving compositions or wire enamels may be made by dissolving the polycarbonate in butyl acetate, a ketone (e.g. cyclohexanone), ethylene glycol monoethyl ether or phenol. In examples polycarbonates were made by reacting diphenyl carbonate with (1) Bis-phenol A, diethylene glycol and 1:3- di(hydroxypropyl) glycerol ether; (2) Bis-phenol A, the di (allyloxy hydroxypropyl) ether of hydroquinone and the tri (allyloxy hydroxypropyl) ether of pyrogallol; (3) Styrenated hydroquinone, the di (allyloxy hydroxypropyl) ether of hydroquinone and the tri (allyloxy hydroxypropyl) ether of pyrogallol; (4) 1:3-di (hydroxypropyl) glycerol ether and the di (hydroxyethyl) of hydroquinone.  Stoving compositions were made by dissolving the polycarbonates in butyl acetate and possibly adding either zinc oxide or titanium dioxide and an ethyl acetate solution of a polysiocyanate.

Filed: 1965-06-17
Abstract: 1,061,108. Switches, partly electromagnetic. PAL - MAGNETON, NARODNI PODNIK. June 17, 1965, No. 25641/65. Heading H2B. [Also in Division G4] A turn indicator switch for a road vehicle is held in a selected operative position for a predetermined time and then released. When the switch arm (P) is moved so that its end engages a contact (c1 or c2) to energize a corresponding signal lamp (S1 or S2) via a flasher unit (U), auxiliary contacts (a and b) momentarily engage and discharge a capacitor (C1) connected between the base and collector of a transistor (T1). The transistor then conducts and current passes through its emitter to two electromagnets (1 and 2) connected in series. One or other of the electromagnets acts on a magnetic extension (Z, Fig. 2, not shown) of the switch arm (P) to hold the arm in the operative position until the capacitor (C1) re.charges and cuts off the transistor, thereby releasing the arm which returns to the neutral position.

Title: Textile yarn winding machines
IPC: B65H54/44
Filed: 1972-06-01
Abstract: 1434916 Yarn winding apparatus JAMES MACKIE & SONS Ltd 24 May 1973 [1 June 1972] 25684/72 Heading D1J A yarn winding apparatus has a single motor that drives both the wind-up-spindle and a traverse mechanism, the spindle and/or the traverse mechanism being pivotally mounted on the motor. In Fig. 1 the wind-up-spindle 8 is mounted on a bracket 16, 18 that rotates about the axis of the motor 2. A belt drive 32 at one end of the motor drives the spindle 8 and a belt drive 40 at the other end of the motor drives the traverse mechanism 10. The drive for the traverse mechanism includes two oppositely tapered pulleys 36, 38 connected by the belt 40. Screw means 50 is used to selectively position the belt 40 via a bracket 52. The position of the belt 40 may be automatically adjusted as a result of the increase in the size of the package being wound. For this purpose the screw 50 extends into an internally threaded screw 54. A wire (56) (not shown) surrounds and is attached to the screwed member 54 and has one end attached to a post 58 moving with the bracket 18. The other end of the wire is also attached to the post 58 but through a spring 60. As the package diameter increases the bracket 18 pivots away from the traverse box 10 and in so doing pulls on the wire 56 which rotates the screw 54. This displaces the bracket 52 and thus the belt 40. The pulley 38 drives the traverse mechanism 10 via a flexible coupling 48 to accommodate angular adjustment of the traverse mechanism relative to the spindle 8.
