Title: Improvements relating to machines for preparing scrap metal
IPC: B30B9/32
Filed: 1958-03-11
Abstract: 830,553. Scrap consolidating. LINDEMANN, W. March 11, 1958 [May 11, 1957], No. 7859/58. Class 83 (4). A machine for cutting up and/or consolidating scrap metal into briquettes comprises a conveyer 36 for moving the scrap between a pair of knives 14, 15 and a ram 12, disposed on the side of the knives remote from the conveyer, for compressing the scrap within a chamber 17 having a closable outlet 24 for removal of the compressed scrap. The machine is used for compressing light scrap metal into briquettes or for cutting up long pieces of heavy scrap. A grab 42 feeds the scrap into a channel 33 from which it is pushed to the left by an hydraulic ram 36 and is periodically precompressed and held by another hydraulic ram 28, which may be formed as a number of rams operated independently, whilst being sheared by a fixed knife 15 and moving knife 14 carried by the main hydraulic ram 12. Ram 36 supports a plate 39 which forms a platform on which the scrap may be loaded, Fig. 3 (not shown), during the advance of the ram. The cut-off scrap falls into chamber 17 and is first compressed by ram 12 and then by a transverse hydraulic ram 19. An hydraulically operated discharge slide 24 is then raised for the briquette to be discharged to a conveyer. Long lengths of scrap, Fig. 4 (not shown), are cut up by the knives 14, 15 and are again cut up by the discharge slide 24 which has a knife edge co-operating with a fixed blade 26. Ram 19 may produce a large force at low speed for compressing light scrap or a small force at high speed for discharging cut-up pieces from the chamber 17.

Title: Preparation of carbalkoxyalkyl-containing organopolysiloxanes
IPC: C08G77/00
Filed: 1958-03-12
Abstract: Carbalkoxyalkylsiloxane polymers and copolymers are made by (1) reacting a cyanoalkylchlorosilane, with or without one or more alkylchlorosilanes, with an alcohol, and (2) reacting the resulting product or products with water.  The silanes may also contain as Si-bonded organic radicals, alkyl, aryl, aralkyl and haloaryl radicals.  Alcohols specified are ethanol, butanol; ethylene-, propylene- and diethyleneglycols; glycerine, pentaerythritol, ethylenechlorohydrin, bromoethylalcohol, chlorobutylalcohol, ethoxyethanol and fluorobutanol, and are preferably used in amount of 1 mol for each cyano-group of the cyanoalkyl silane plus 1 mol for each Si-bonded Cl atom in the hydrolysable composition.  The reaction is effected by mixing the reactants, and preferably heating the mixture at 50 DEG C. to the reflux temperature of the mixture, and thereafter adding sufficient water to effect the hydrolysis, while maintaining the temperature between 25 DEG  and 60 DEG C.  In typical Examples (1) molten cyanoethyltrichlorosilane was added to methanol and the mixture was refluxed for 3 hours, after which excess water was added causing precipitation of an oil which, after separation and washing, became a hard, resinous solid upon standing at room temperature and was found to consist of CH3OOC,CH2, CH2,SiO 3/2 units; (6) a mixture of trimethylchloro- and cyanoethyltrichloro-silanes was added to ethylene glycol and the resulting solution was heated at 60 DEG C. for 1 hour; water was then added and the resulting oily phase was separated and dried to yield an oil which gelled on standing at room temperature.  Uses: as plasticizers for siloxane resins and rubbers and vinyl halide resins; and as lubricants.  The cyanoalkylsilanes may be made by effecting reaction between (1) an olefinic hydrocarbon containing a cyano group, e.g. acrylonitrile, methacrylonitrile, allyl cyanide, crotyl cyanide or a -chloro-acrylonitrile, and (2) a silane having Sibonded H, e.g. HSiCl3, CH3SiHCl2 or C2H5, SiHCl2, using as catalyst a secondary or tertiary amine, or sodium methylate. Specification 839,374 is referred to.

Title: Improvements relating to processes for grinding materials
IPC: B02C19/00
Filed: 1930-03-12
Abstract: In the dry grinding of cement clinker, gypsum powder, &c., the material to be ground has mixed therewith a segregating agent capable of imparting a dispersive propensity to the pulverized particles being ground.  The segregating agent comprises material which when rubbed against the particles being ground generates static electric charges in the particles which induces mutual repulsion; for cement and cement clinker the segregating material is resin or a resinous material.  The segregating material may be used alone or with a diffusing material such as plaster of Paris or hydraulic cement, the pulverized resin being mixed with the diffusing material together with a sufficient quantity of water to set the mixture.  In the manufacture of cement, 1 part of resin to 5 parts of plaster of Paris or hydraulic cement may be used, and 1 part of this mixture is placed in the mill with each 200 parts of cement.  The segregating and diffusing material is less resistant to abrasion than the material being ground.ALSO:In the dry grinding of cement clinker, gypsum powder, &c. the material to be ground has mixed therewith a segregating agent capable of imparting a dispersive propensity to the pulverized particles being ground.

IPC: B60B9/26
Filed: 1918-05-14
Abstract: 126,786. Baggs, C. E. May 14, 1918. Spring wheels with sectional outer guided members.-The. spokes a are hollow and carry pistons c connected by links d to shoes e, the shoes being pivoted together at e<2>. The shoes bear against a solid tyre f. Bellows are mounted in chambers a<3>between the spokes, and are provided with valve chambers k, Fig. 5, so that, on the expanding stroke of the bellows, air is taken in at k<7>, and when the bellows are compressed by the pressure of the tyre on the road, air is forced through the passage k<3> into a tube m<1>. Fig. 1, the opposite end of which leads into a chamber x of the neighbouring spoke a, thus increasing the air pressure in the next spoke to support the wheel. In this way, the air pressure is increased until it is equal to or greater than the pressure in the bellows at the moment of compression. A detachable rim a<6> protects the working parts from dust. The chambers k may contain springs to operate before the air pressure is sufficient to support the wheel. The bellows may be replaced by pistons.

Inventor: HARDING OLIVER
IPC: B63H21/22
Filed: 1918-05-16
Abstract: 122,977. Harding, O., and Keppie, P. R. May 16, 1918. Clutches, claw; shaft couplings.-In clutches and couplings for use in connecting up the shafts of receiving and transmitting instruments in ships' telegraphs &c., in which the clutch &c. can only be engaged when the pointers are similarly situated, a sleeve 3 secured on the driven shaft 1 carries a rotatable disk 6 with notches 8 as numerous as the possible number of orders to be transmitted, one notch 9 being so deep that when a tooth 12 on the sleeve 5 sliding on the driving- shaft 2 fully engages the notch, clutch teeth 13 on the sleeve engage corresponding clutch teeth on the sleeve 3. When the clutch is disengaged as shown, the tooth 12 engages with the notches 8 in succession and rotates the disk 6 one step for each rotation of the shaft 2, so that the shaft must be rotated until the pointers have their former relation before the clutch can again be engaged. Flat surfaces 14 on the disk 6 and also, in modifications, flat surfaces on a boss on the disk or on a shroud covering the notches 8 co-act with the face 15 on the sleeve 5 in the manner of a Geneva-stop device to prevent accidental rotation of the disk. Fig. 10 shows a coupling for the same purpose in which the dish 6 is rotated by the tooth 12 until the deep notch 9 registers with slots in the shaft 2 and in a sleeve 17 on the shaft 1, so that a cotter 16 may be inserted to couple the shafts together. The cylindrical periphery of the plate 18 carrying the tooth 12 may be arranged below the disk 6 and engage curved recesses between the notches 8 to prevent accidental rotation of the disk.
