Abstract: 900,865. Scrap consolidating; shearing. LINDEMANN, W. July 7, 1960 [Dec. 31, 1959], No. 23800/60. Class 83 (4). A machine for consolidating and cutting-up scrap B comprises a trough 32 containing a ram 31 for pushing the scrap B towards cutters 23, 25, and a jaw 42 pivoted on a longitudinal edge of the trough and supporting large pieces of scrap which it consolidates by movement towards an opposed surface. This surface may consist of an extension of the trough (Fig. 14, not shown), or another jaw 42, which may be in the form of an extra trough (Fig. 15, not shown) for the scrap. The jaws have teeth or hooks 51, 53 and are operated independently by hydraulic cylinders 47 to crush the scrap in stages until it falls into the trough. It is then advanced by the hydraulic ram 31 to one or more vertical rams 29 driven hydraulically independently of each other so as to further consolidate the scrap. After the rams 29 have been raised, the ram 31 advances the scrap to the cutter 25 which is lowered by a cylinder 26 and raised by cylinders 28. A bar 54 strips scrap from a rearward extension plate 38 on the ram 31 on return movements of the ram.

Abstract: 723,834. Mechanical wheeled toys. MULLER, H. Sept. 23, 1952, No. 23859/52. Class 132 (3). A self-propelled toy vehicle has a mechanism for controlling the vehicle or accessories of the vehicle. In a toy automobile propelled by a spring motor, each time a control spindle 2 is moved from the position shown in Fig. 1 to that shown in Fig. 2, a four-lobe ratchet wheel 22 and a control member 26 are turned a quarter of a revolution thus permitting a sequence of control operations to be carried out. A spindle 8 carrying a pinion 6 and an eccentric governor member 6<SP>1</SP> engages one of the faces or edges of a part 10 of the control member 26, and in Fig. 1, the spindle 8 is positioned on the part 10 such that the pinion 6 is clear of a gear 55 of the spring motor, the eccentric 6<SP>1</SP> thus remaining stationary. Fig. 2 shows gear 55 and the pinion 6 in engagement, the speed of the vehicle now being reduced by the rotating eccentric 6<SP>1</SP>. Additional control may be provided by spring wires 30, 31 (Fig. 5) mounted on the control member 26, the wires in certain positions of member 26 bearing on the spindle 8 and causing a further reduction in speed or even stopping the vehicle. Forward and reverse control is effected by a cam 36 mounted on an extension 35 of the control member 26, rotation of the cam causing engagement of a drive pinion 45 with one or other of gears 43, 44 (Fig. 6). Means for automatically stopping the driving mechanism during this drive change is provided. A lever 15 which extends to the rear of the vehicle permits forward and reverse control by a handle 16 (Fig. 1) if a link 41 is removed. The spindle 2 is movable vertically by lifting a remote control cable 21 or by exerting downward pressure on a plate 53 (Fig. 1) linked to a flange 3 on the spindle 2. In a modification, the spindle is lifted by horizontal pressure on a plate portion 48 of an arm 47 (Fig. 2). More than four control positions of the ratchet wheel and control member 26 may be provided. The toy is steered by rotating the cable 2<SP>1</SP> and spindle 2 which is connected by pulleys and an endless string to the front axle assembly. The control of accessories includes switching on or off a lighting system or flashing indicator lights, or operation of a horn. Electric drive for the vehicle is specified.

Abstract: 1428216 Insulating pipes SHAW PIPE INDUSTRIES Ltd 23 May 1973 [30 May 1972] 24636/73 Heading F2P A method of thermally insulating pipe 10 includes the steps of axially rotating the pipe 10 at a uniform speed about a substantially horizontal axis while applying a plastic foam mix to the surface of the pipe 10 progressively along its length, simultaneously forming a tube 18 of larger diameter than the pipe 10, the tube 18 being progressively extended coaxially with the pipe 10 and progressively enveloping the newly coated surface of the pipe, and maintaining the pipe 10 at a temperature at which the mix constituents will react to form a foamed mass 25 enveloping the pipe and filling the space between the pipe surface and the tube 18. As described a steel pipe 10 is supported by driven wheels 12, 13 which simultaneously rotate the pipe 10 and advance it axially through a first region where a polyurethane foam mix is applied to the pipe 10 by spray nozzles 15, 16. The coated pipe then moves through a tube forming machine 19 where an interlocked helically wound tube 18 is formed from strip material 20. The completed insulated pipe is also rotated and advanced by devices 24 similar to the wheels 12, 13. The pipe 10 and possibly the strip material 20 are preheated. The strip material 20 which forms the tube 18 is preferably metal, e.g. galvanized sheet steel, but may also be thin gauge foil, laminated foil, cardboard or any suitable material having a thickness of not less than À008 inch. In a first modification (Fig. 3) the foam 25 is reinforced by a web 26 of glass fibres which is wound on to the pipe 10 between sprays 15 and 16. In a second modification (Fig. 6) the tube 18 is formed with helical corrugations 43 and the seam 40 has just sufficient free play to permit some relative axial movement between adjacent convolutions of the strip forming the tube 18. The joint 40 also includes neoprene gaskets 41, 42. This arrangement compensates for differing thermal expansions and contractions of the tube 18 and pipe 10.
