Title: Improvements in organo-silicon halides
IPC: C07F7/12
Filed: 1947-01-27
Abstract: Organo-silicon polymers are obtained by hydrolysing diorgano-monohalosilanes of the general formula <FORM:0622970/IV (a)/1> wherein R represents an aralkyl or aromatic radical, R1 represents an alkyl, aralkyl or aromatic radical and X is a halogen, to give compounds of the type <FORM:0622970/IV (a)/2> in which the end blocking hydrogen is displaced by oxygen under mildly oxidizing conditions to give polymers containing the radical <FORM:0622970/IV (a)/3> wherein n is a whole number.ALSO:Organo-halosilanes of the general formula <FORM:0622970/IV (b)/1> wherein R represents an aralkyl or aromatic radical, R1 represents an alkyl, aralkyl or an aromatic radical and X represents halogen, are prepared by reacting an inorganic trihalosilane, or a mono-organo-dihalosilane containing one of the desired R or R1 substituents with at least its molecular equivalent of an organo-magnesium halide in the presence of an ether as the reaction medium, e.g. the reaction may be carried out at temperatures of 0 DEG  C. and below.  An inorganic trihalosilane, e.g. trichlorosilane, may be reacted with approximately two molecular equivalent weights of an organo-magnesium halide.  The organo-magnesium halide may be an aryl-magnesium chloride or bromide. Trifluoro- or tribromo-silane may be used in place of trichlorosilane.  In examples, the preparation of the following compounds is described: di-p-methylphenyl-, diphenyl-, dibenzyl-, ethylphenyl-, methylphenyl-, p - chlorophenyliso - propyl-and benzylethyl - monochlorosilane.  Similarly, benzylmethyl- and diphenyl - mono - bromosilane, dinaphthyl-, p-bromophenylisopropyl-, phenyldodecyl- and phenyloctadecyl-monochlorosilane may be prepared. The halogen atom in the organo-halosilanes may be displaced by reaction with an alcohol to yield the corresponding monoalkoxydiorganosilanes.

Title: Improvements in or relating to Color Photography.
IPC: G03C7/26
Filed: 1918-02-19
Abstract: 113,618. Hess-Ives Corporation, (Assignees of Ives, F. E.). Feb. 20, 1917, [Convention date]. Colour photography.-In the production of multi-coloured photographs by printing one or more monochromes directly upon a pre-formed monochrome component, the images of the positives or negatives used for printing the superposed images are coloured so a.s to contrast with the image printed upon; registration of the printing member and the component printed upon is thus facilitated, as inaccuracies in the register produce colour fringes. The invention may be applied to a two-colour process in which a blue-green positive is produced from a red-representing negative, and a green-representing negative or a diapositive therefrom is used to print upon the blue-green positive, the blue-green positive 'being re-sensitized vrith bichromate or having a sensitive layer applied to it before the second printing, and the second print being selectively dyed. The colouring of the image of the green-representing negative or of the diapositive may be effected by copper toning it and subjecting the toned image to a red dye which is mordanted by the copper. The second print is dyed with a red dye which is selectively absorbed by the hardened gelatine or by the unhardened gelatine according as a negative or diapositive is printed from. A formula for a copper-toning solution is set forth in the Specification.

Filed: 1941-03-05
Abstract: 547,680. Vehicles with removable bodies. DEMPSTER BROS., Inc. March 5,1941, No. 3015. Convention date, April 27, 1940. [Class 108 (i)] [Also in Group XXX] A load container is lifted from the ground and deposited upon a vehicle by a lifting boom pivoted upon the vehicle, assisted by an upwardly extending skid or runway upon which the container runs as it is lifted and lowered, the skid being movable forwardly from an end position to enable the container to be deposited in a suitable position on the vehicle. The container may be tipped by lowering the boom. The boom and skid may fold down to permit the mounting on the vehicle of a passenger or other body. Longitudinal channel members 2 secured to the main side members 1 of the vehicle provide runways for rollers 4 of an upwardly extending skid or runway 7 provided with rollers 8. A boom 13 hinged at 13<SP>1</SP> to the members 2 comprises a pair of arms and a cross-piece 13<SP>11</SP> and is adapted to be raised by hydraulic cylinders 14. To load the container 11 on to the vehicle the skid 7 is moved by a hydraulic cylinder 5 to the rear end of the vehicle, the boom 13 is lowered to enable chains 16 to be attached to projections 18 on the container. As the boom is swerving upwardly the container slides first against an apron 19 secured to the bars 2 and then along the skid 7. Exhausting the cyllinder 5 permits the skid to move forwardly and upon lowering the boom to the position shown in Fig. 1, the container is deposited upon the inclined ends of bars 12 secured to the channels 2. The container has hinged to the bottom thereof at 27 a loop or bail 10 which upon raising the container engages a hook 9 and upon lowering the boom with the hook so engaged and the skid in the rear position, the container tips about its pivot 27 to dump the load on to the ground. In the tipped position the chains 16 pass around projections 30 whereby the return of the container is facilitated when the boom is again swung upwardly. By raising the container sufficiently on the skid the bail is disengaged from the hook and the container may then be deposited on the ground. The hook may be constructed as described in U.S.A. Specification 2,121,121. By removing one pair 6<SP>1</SP> of the bolts by which the skid is secured to its wheeled carriage 3, it may be folded down about the other pair 6 between the bars 2. The boom 13 may be folded down to rest upon the bars 2. A passenger body may then be mounted on the vehicle, comprising a platform or seat part 35 resting upon the boom 13, inner vertical walls 36, outer walls 136 spaced from the walls 36 to provide leg room and connected by floor parts to the walls 36 and upper members 38, 39 40. The body is secured by U-bolts. and pegs to the boom 13 and members 2.

Title: Machine and method for producing an expansible lattice structure in particular for a reinforcement of a pipe having a socket and the lattice structure obtained
IPC: E04C5/06
Filed: 1973-01-22
Abstract: 1394501 Making lattices; corrugating and winding TREFILUNION 22 Jan 1973 [3 Feb 1972 15 Jan 1973] 3105/73 Headings B3A and B3E An expansible cylindrical or conical lattice structure, e.g. a reinforcement for a concrete pipe having an enlarged socket at one end, is formed by winding a helical wire round an assembly of longitudinal wires 1, one end of the helix being corrugated as at 3a so that the end can be enlarged. The apparatus shown comprises a rotary driven plate 6 on a headstock 5 and a rotatable plate 9 on a tailstock 8. The longitudinal wires 1 are attached to plate 9 and are drawn through plate 6 from supply reels 12 mounted on the plate as the tailstock moves along runway 11. Simultaneously the headstock is rotated to wind on the helical wire 2 from a supply reel 15. A fixed welding electrode 17 cooperates with successive electrodes 18 on plate 6 to weld wires 1, 2 at their intersections, welding switch 20 being operated by successive actuators 19. Wire guides (not shown) feed wire 2 between corrugating wheels 26a, 26b, the latter being movable by jack 34 controlled by fixed switch 43 and ramp 44 on tailstock 8, so that only the end portion 3a of the helical wire is corrugated. The wheels 26a, 26b have flat sided teeth, the sides meeting at an angle slightly less than a right angle. The drive to the shaft 24, Fig. 6, of the movable wheel, is through spur gears 29a, 30a, 30b, 29b, gears 30a and 30b being mounted in bearings movable in arcuate slots centred on the axes of gears 29a, 29b and urged as shown by springs 33a, 33b, so that the drive engages as the corrugating wheels come together. The corrugating drive motor is also controlled by switch 43. In an alternative embodiment, the tailstock is stationary, and the supply reel 15 and electrode 17 are moved along together with switch 43 which co-operates with a fixed ramp. To facilitate making the enlarged end of the finished reinforcement exactly concentric with and parallel to the remainder, a ring of wire perpendicular to the longitudinal axis of the reinforcement may be added at the end of the corrugated section, either as a separate item or by halting the relative movement between the longitudinal wires and reel 15 for one revolution of the plate 6.

Title: Improvements in or relating to the manufacture of coloured artificial materials having a basis of regenerated cellulose
IPC: D01F2/06
Filed: 1937-02-04
Abstract: In the production of artificial filaments, threads, yarns, ribbons, films, foils, and like materials by the extrusion of a solution of cellulose into a coagulating liquid, colouration of the extruded materials is effected by incorporating a dyestuff derivative uniformly in the coagulating liquid and thereafter converting the derivative to the parent dyestuff on the materials. If desired, the extruded materials may be passed through a plurality of coagulating baths of progressively increasing coagulative power, and the dyestuff derivative may be incorporated in a coagulating liquid of lesser coagulative power. When using a plurality of coagulating baths a dyestuff itself may be used instead of a dyestuff derivative and in this case no conversion step is required.  The solution of cellulose may be viscose or a cuprammonium solution of cellulose.  The dyestuff derivative may be a leuco compound of a vat dyestuff or a sulphuric or other ester of such leuco compound.  Solubilized vat dyes known as Indigosol and Soledon may be used.  Development of the colour may be effected in the washing gutter, spinning funnel, or centrifugal spinning box.  Dyestuffs readily soluble in water and having an affinity for regenerated cellulose such as the Icyl dyes may be used. The coagulating bath for viscose may be a solution of sulphuric acid and an aryl sulphonic acid or a salt such as sodium, ammonium, or zinc sulphate, or an aryl sulphonate. Glucose, or a wetting or dispersing agent such as a sulphonated higher fatty alcohol, may be added to the coagulating liquid. Viscose may be extruded into a solution of sodium or ammonium sulphate containing a dyestuff or dyestuff derivative, and the filaments may then be passed into a solution of sulphuric or an aryl sulphonic acid to complete the coagulation process.  In an example, a cuprammonium solution of cellulose is extruded into hot water containing a small proportion of sodium sulphate and the brown dyestuff obtained by coupling tetrazotized 4.41-diamino-diphenylether with one molecule of 1-amino-5-naphthol-7-sulphonic acid (alkaline coupling) and with one molecule of 1-naphthol-4-sulphonic acid.  The filaments are then led into a strong solution of caustic soda containing sugar. The filaments are then washed and dried.  The Provisional Specification comprises also the colouration of regenerated cellulose materials by introducing a dyestuff component such as a diazotizable compound or a coupling compound into the coagulating bath, and subsequently performing the diazotizing and coupling operations on the formed materials, or by adding both diazotizable compound and coupling compound to the coagulation bath, and subsequently diazotizing.
