Title: Improvements in machines for moulding concrete and other materials requiring compaction
IPC: B28B7/10
Filed: 1959-05-07
Abstract: 927,432. Moulding multi-duct concrete conduits. GAGNE ENTERPRISES Inc. May 7, 1959 [May 7, 1958], No. 15708/59. Class 87(2). Concrete articles are moulded in a machine which has a mould 22 in two parts 23, 24 secured together by bolts 39 which pass through angles 36, 37 on the mould halves with rubber spacers 38 between them, whereby the two parts can move slightly when the mould is vibrated. The mould halves have angles 28 welded at their lower ends by which they are fixed to a deck 21 by spring-loaded bolts with a resilient pad 31 interposed. Mandrels 52 extend upwards, through an opening 57 in the deck 21, being fixed at their lower ends to a cross-member 56. The mandrels pass through a lower pressure platen 58 which largely closes the lower end of the mould halves, having resting on it a transfer platen 59. Rings 61 on the lower pressure platen pass through the transfer platen and are shaped to mould chamfers on the ends of the ducts in the product resulting from the mandrels. The upper end of the mould is closed by a platen 73, pressed down from a crosshead 76 by a spring 74, the crosshead being movable through a rod 78 connected to a hydraulic cylinder, the plate 73 being raised with it through guide pins 79. The upper ends of the mandrels seat in rings 83 on the upper pressure platen 73 which are shaped to chamfer the upper ends of the ducts. A rod 67 is raised by a hydraulic cylinder 69 and moves the lower pressure platen into position. The mould is filled with concrete from a hopper 87. The upper pressure platen 73 is then placed in position and the mould is vibrated by vibrators 47, the mould halves moving relatively to transmit the vibrations. The vibrators are attached to one or more brackets 46 on the mould sides. After vibration, the upper pressure platen 73 is removed and the rod 67 raises the lower pressure platen 58 and the transfer platen 59 till they eject the moulded conduit, which is removed on the transfer platen. Specification 927,433 is referred to.

Filed: 1953-06-09
Abstract: Salts of carbamic acids the nitrogen atom of which carries a free hydrogen atom and also a higher aliphatic hydrocarbon radical with an amine derived from the carbamic acid by loss of carbon dioxide are prepared by reacting the addition product of an alkali metal bisulphite and a higher aliphatic isocyanate with sodium hydroxide in a heated aqueous medium.  The emulsion produced may be salted out by addition of sodium chloride.  The term "higher aliphatic hydrocarbon radical" is defined as having an uninterrupted chain of at least eight carbon atoms as well as radicals whose carbon chain is interrupted by hetero atoms or groups of hetero atoms.  The preparation of such a salt from sodium bisulphite and stearyl isocyanate (i.e. a mixture of octadecyl and hexadecyl isocyanates) is described. Specifications 654,163 and 655,541 are referred to.ALSO:Cotton, regenerated cellulose, cellulose acetate, wool, silk and nylon textiles may be rendered resistant to shrinking by the addition of resin-forming substances such as methylol urea or the condensation product of melamine, formaldehyde and methyl alcohol to a water proofing bath comprising an aqueous dispersion or emulsion of a salt of a carbamic acid, the nitrogen atom of which carries a free hydrogen atom and also a higher aliphatic hydrocarbon radical with an amine derived from the carbamic acid by loss of carbon dioxide.  The impregnated fabric is dried at a temperature above 100 DEG C.  The term "higher aliphatic hydrocarbon radical" is defined as an aliphatic radical having an uninterrupted chain of at least eight carbon atoms as well as radicals whose chain is interrupted by hetero atoms or groups of hetero atoms.  Paraffin or wax emulsions may be added to the impregnating bath.  If desired the impregnated fabric may be treated with a dispersion of a soap of a polyvalent metal prior to drying, or a soap may be added to the impregnating bath and the impregnated material treated with a water-soluble salt of a polyvalent metal such as aluminium acetate, zirconium oxychloride, zirconium acetate, or zirconium formate.

Filed: 1952-06-25
Abstract: 727,676. Photographic transfer process. KODAK, Ltd. Sept. 1, 1953 [June 25, 1952], No. 16008/52. Class 98 (2). Transfers are obtained from an exposed material containing a light-sensitive diazo compound, by contacting it in the presence of moisture with an absorbent receiving support, whereby diazo compound diffuses from the unexposed parts into the support, where it is caused to couple with an azo dye coupling compound in the presence of alkali. Up to twelve copies can be obtained by repeating the process. The receiving support is preferably impregnated with alkali and the coupling component before being contacted with the exposed material, but it may contain the coupler only and be treated after contact with ammonia gas or an alkaline solution, or ammonia solution may be used to moisten it before it is contacted with the exposed sheet. Plain paper also may be used as a receiving sheet being treated, after contact with an alkaline solution of the coupler. The moisture required for the transfer may be contained in the receiving sheet as water of crystallization of an alkaline salt, such as Na 3 PO 4 .12H 2 O. In this case the sheets are not moistened, but contacted under pressure at 130‹ C. for 5 seconds, when the water of crystallization is released. The diazonium salt used for the sensitized sheet may be derived from di-ethyl amino toluene hydrochloride, 3 - methyl - 4 - (N : N - di-ethyl amino) aniline, 4 - (N - ethyl - N - ethoxy ethyl amine) aniline, 2 : 5 - dimethoxy - aniline, p : p<SP>1</SP>- diaminostilbene, 3 - methyl - 4 - amino - N- ethyl - N - [# - (methylsulphonamido) - ethyl]- aniline, 2 - methoxy - 4 - amino - 5 - methyl - N : N-diethyl aniline, 4-amino-diphenylamine, N - (4 - aminophenyl) - piperidine, or 1 : 8- dihydroxy - 2 - (p - aminophenylazo) - 3 : 6- disulphonaphthalene.

Title: Method for the preparation of wood pulp
IPC: D21C1/00
Filed: 1945-06-22
Abstract: Wood chips are subjected to the action of steam or water for 0.4 to 1.75 hours at 300 DEG  to 375 DEG  F. and are then treated with a pulping solution comprising sodium sulphide and sodium hydroxide in a ratio of 1 part of sulphide to 0.8-1.5 parts of sodium hydroxide, the total concentration of the two sodium compounds, calculated as sodium oxide, being 4-8 per cent by weight of the solution, at a temperature of 300 DEG -400 DEG  F. until a readily bleachable pulp highly reactive in esterification is obtained. The water or steam may be used alone or with a small quantity of a carboxylic acid such as formic or acetic acid, but the usual pulping agents such as sodium hydroxide are absent during the first stage of the treatment.  After the pulping treatment with sodium sulphide and hydroxide, the pulp may be bleached by treatment with chlorine and with sodium or other hypochlorite. The bleaching may be followed by treatment with hot or boiling dilute alkali solution.  The finished bleached pulp has a high content of alpha cellulose and it has high viscosity characteristics.  It may be used in the preparation of cellulose acetate, propionate, butyrate, or other cellulose ester.

Abstract: 1,143,964. Vehicle anti-theft devices. L. C. H. JUY. 12 April, 1966 [13 April, 1965], No. 16034/66. Heading B7J. A body 1 fixed to and arranged to lock a vehicle steering column B comprises a lock 2 and intermediate member 5 which when rotated by the key against the pressure of a ball 14 causes a bolt 7 provided with a head 7r to move radially and outwardly of the body towards engagement with a sleeve M on the steering column. In the Fig. 1 position the column is shown unlocked and a reduced neck portion of the bolt 7 engages in a slot in a sleeve 8, which sleeve may in this position be rotated as described in Specification 1,143,963, to make electrical, e.g. ignition circuits. When however the key 17 is turned, an eccentric stud 5a is also turned and lifted so that a spring 9 acting on a finger 7b moves the bolt 7 upwardly to an intermediate position in which the enlarged lower part of the bolt passes through an enlarged portion of the slot in the sleeve 8, Fig. 6b (not shown), and prevents the sleeve from rotating, Figs. 6-10 (not shown), but the steering column remains unlocked as the head 7r does not engage the sleeve M so that the car may be moved (as in a garage) but not started. In this position a ball (11), Fig. 8 (not shown), engages in a recess (7m) in the bolt. In Figs. 11-15 (not shown), further rotation of the member 5 causes the stud 5a temporarily to engage a cam slot in the bolt 7 and lift the bolt higher until the ball (11) engages in a recess (7n), Figs. 13 and 17 (not shown), in which latter figure the ball pushes the bolt 7 upwardly and in this position both the sleeve 8 and the column B are prevented from rotating so that the vehicle may be neither steered nor started.
