Title: Street sweeper
IPC: E01H1/04
Filed: 1952-02-18
Abstract: 698,855. Road-sweepers. DEMPSTER BROS., Inc. Feb. 18, 1952 [April 19, 1951; Jan. 9, 1952], No. 4263/52. Class 107 A power driven road sweeping machine has detachable refuse containers which can be lifted and lowered to and from a transporting position and a collecting position by power operated means. Provision is made for the containers to be emptied whilst on the machine. The machine has two spaced front wheels 2 between which the container 54 is held in an elevated position by arms 59 hydraulically operated by the ram 67 acting through lever 62. The main brush 22 feeds the refuse into an enclosure 27 containing an elevator which is arranged to discharge the refuse into the container 54. If desired the road ahead of the brushes can be sprinkled with water. Three constructions of container are disclosed, two having pivoted side doors arranged to open when the container is tilted, and one having a pivoted bottom retained in position by suspending arms 59 which engage lifting pins 45 on the bottom side plates 53. The enlarged view in Fig. 9, shows a modified construction of the container lifting gear in which the hydraulic ram acts throughthe doublearmed levers 105, pivoted at 106, to raise the arms 109 to the full line position, in which position the straight line joining the pivot 108 and lifting pins 98 falls to the left of the pivots 106 so that the container is locked into its transporting position by its own weight. As shown, in chain lines, when the container is lowered, the suspension hooks between the hook 110 and pin 98 so that the sweeper can be driven away from the container and driven up to an empty one. By a detachable arm 112 and its associated equipment, the top part 99 of the container can be prevented from dropping and in consequence the bottom of the container pivots open on pivot 96. Dumping can thus be effected with the container retained on the' sweeper. By lowering the arms 109 and fitting extension hooks between the hook 110 and pin 98, the refuse can be dumped in a pit. The containers are provided' with a dumping bail which functions to tilt the container for emptying when it is desired, and to effect this it engages a suitable projection on the transporting and dumping vehicle.

Abstract: 536,927. Signalling over power circuits. GENERAL ELECTRIC CO., Ltd., CHUBB, A. A., and SHERWOOD, L. A. March 8, 1940. No. 4331. [Class 40 (iv)] Signalling currents are applied simultaneously in opposite phase to two feeders or groups of feeders thereby minimizing the signalling voltage developed across the power generator or transformer which supplies the feeders. As shown in Fig. 1, signalling currents of opposite phase are applied from generator VS over transformers IT1, IT2 to feeders F1, F2. The feeders and transformer sccondariesconstituteabalanced bridge circuit if the feeders are of equal impedance so that no signal voltage is developed across the bus-bars LT1, LT2 and power generator LS. In the arrangement described with reference to Fig. 2 (not shown), two groups of low voltage feeders are supplied by two groups of high voltage feeders to which the signalling currents are applied in opposite phase. An arrangement for signalling over two threephase ring mains 11-16 and 17-22 is shown in Fig. 3. Coupling at power frequency between feeders due to the injection circuits may be reduced by increasing the leakage coefficient of the transformers at that frequency and reducing the impedance of the signal generator. Signalling currents applied to the first ring main from generator VFG over transformers 26, 27  are in opposite phase to those applied to the second main over transformer 28, 29.

Condensing processes; scrubbers.-Tar, pitch, and tarry oils are distilled by direct contact with hot uncooled coal gases in a still which is also externally heated. The hot gases may be scrubbed before entering the still by direct contact with the residues from the still or with pitch of the same composition as that carried in suspension in the gases. In a coke oven battery provided with the usual up-take pipes 4, the greater part of the gases pass through a pipe 14 and spray head the usual condensers 8, 9. The remainder of the gases are passed through a pipe 14 and spray heat 15 into the tar in a still 13 which is heated externally by flue gas from the plant circulating through a bye pass 42. The tar from the collector main passes through a pipe 11 to a decanter 12 from which it is supplied to the still 13 through a pipe 6<1>. The gases leave the still 13 by a pipe 16 and after passing through condensers 23 are returned to the main stream through pipes 21<1> or 24. The still 13 may be of the horizontal type shown in Fig. 6, or alternatively a vertical still 71, Fig. 9, may be used provided with baffles 73 down which the tar, supplied from a pipe 72, trickles, the hot gases being admitted through a pipe 74 and passing away through a pipe 75. In a further modification, a tower still provided with baffles in its upper portion and spray nozzles in its lower portion may be employed. In a further modification, Fig. 5, the coke oven plant is provided with two collector mains 342, 343 so that the richer gases may be collected separately from the leaner gases, and the gases are passed through a scrubber before introduction into the still. Specifications 158,852; 165,230, 170,140, and 239,841, [all in Class 32, Distilling &c.], are referred to.

Title: A process for dyeing or printing fibrous material of a thermoplastic synthetic resin
Inventor: LAUCHENAUER ALFRED
IPC: D06P3/00
Filed: 1952-02-27
Abstract: In the dyeing or printing of fibrous material of a thermoplastic synthetic resin, improved dyeing effects are obtained by treating the material with a solution of cellulose, a protein or polyvinyl alcohol, the cellulose, protein or polyvinyl alcohol then being precipitated, or in the case of polyvinyl alcohol insolubilized, on the material prior to the dyeing or printing operation.  In addition, the treatment imparts increased wearing properties, an improved feel or handle, an increased resistance to light radiation and to the build-up of static electricity and an increased water-absorption to the dyed material.  The process is applicable to dyeing with acid, direct, vat, acetate, indigosol and naphthol dyestuffs as well as to printing and discharge printing.  The solution, which may contain softening, hydrophobing or flameproofing agents, may be applied locally, if desired, when two-colour effects may be obtained by dyeing with different dyestuffs having affinity for the treated and untreated material.  During or after precipitation or insolubilization of the substance a treatment with an aldehyde or a heating step to a temperature higher than the softening point of the fibrous material may be applied.  Heating may be effected indirectly or by direct contact with hot gases, liquids or solids, and may be effected during hot washing, drying, embossing, glazing or ironing. Specified fibrous materials are staple fibres, yarns, threads, fabric and knitted goods of polyamides, polyurethanes, polyesters and polyvinyl compounds, which may be associated with non-thermoplastic fibrous materials. Fibrous material treated according to the process may be associated with untreated fibrous material or natural fibres in weaving, knitting or embroidery.  Examples describe (1) the treatment of polyamide fibres with cellulose xanthate solution, followed by precipitation with aqueous hydrochloric acid, drying and dyeing with a direct dyestuff; (2) the printing of a polyester fibre-fabric with cellulose xanthate solution followed by precipitation, drying, and dyeing first with a direct dyestuff and then with an acetate dyestuff to give a two-colour effect; (3) the printing of a polyester fibre-fabric with ammoniacal casein solution followed by precipitation with aqueous oxalic acid-formaldehyde solution, drying and dyeing with an acid dyestuff and then with an acetate dyestuff to yield a two-colour effect; (4) the treatment of polyacrylonitrile fibres with a cellulose solution as in (1) and then dyeing with an indigosol dyestuff; and (5) the printing of a polyacrylonitrile fibre-fabric with aqueous polyvinyl alcohol followed by heating at 130 DEG C. to insolubilize the polyvinyl alcohol and dyeing the printed parts with a direct dyestuff.
