IPC: B23Q11/10
Filed: 1953-08-27
Abstract: 739,306. Coating with metals. AMERICAN VISCOSE CORPORATION. Aug. 27, 1953 [Oct. 6, 1952], No. 23688/53. Class 82 (2). Apparatus for fusing an applied coating of metal on to a metal base, e.g. coating a steel base with lead, comprises a supporting member 5 for a work-piece, an elongated beam 6 from which a carriage 7 is suspended, and cam-operated electric control means for moving the torch assembly 21 in a plane perpendicular to the direction of advance of the carriage. An armature 39 movable against a spring 44 in a coil 46a effects vertical movement of the torch, and a similar arrangement of springs on a rod 47, and horizontal solenoids, effect horizontal movement. The carriage is advanced by movement of the armature 57 in a solenoid 58a operating a one-way clutch to drive the roll 54 engaging the beam 6. The operation of the solenoids is effected in turn by cam members on a driving-shaft operating electric contacts to cause the torch assembly 21 to scan the workpiece, it being lifted away therefrom at the end of each traverse while the carriage is advanced along the beam.

Title: Block polymers of c(-olefins and process for preparing same
IPC: C08F4/642
Filed: 1956-08-01
Abstract: Linear, head to tail, high molecular weight polymers of an alpha-olefin of general formula CH2 = CHR, where R is a lower aliphatic radical are produced by preparing a polymerisate by the method discussed in the parent Specification and thereafter extracting it stepwise with a series of solvents which have increasing dissolving powers so as to dissolve first only the amorphous nonisotactic polymers and then fractions consisting of block polymers with increasing crystallinity percentages, leaving the isotactic polymers undissolved.  Thus where the polymer is from propylene the extraction is conducted stepwise with ethyl ether which dissolves substantially the non-isotactic amorphous polymers and then in succession with isopropyl ether and n-heptane.  Poly-alpha-butenes and poly-alpha-pentenes are also specified.  Extruded and moulded articles may be prepared from the products.

Title: Improvements in or relating to the purification of gaseous helium
Inventor: MARSH WILLIAM ROBERT
IPC: C01B23/00
Filed: 1962-06-20
Abstract: <PICT:0998771/C1/1> Gaseous helium is purified by effecting a catalytic combination of gaseous oxygen and hydrogen present, passing the gas through a molecular sieve to remove H2O vapour formed; passing the resultant gas through an oxidation stage to oxidize residual H2 to H2O and CO to CO2, then through a second molecular sieve, a getterer to remove residual oxygen and nitrogen, and then possibly through a third molecular sieve.  In Fig. 1, helium is introduced through control valve 2 into catalytic chamber 3 where O2 and H2 impurities combine, and the gas mixture is passed into molecular sieve 6 which contains molecular sieve material type 5a (calcium aluminosilicate) at, e.g. 20 DEG  C. to remove water vapour. The gas then passes through a two-stage oxidation means which consists of (a) silica tube 67 containing copper oxide heated to 630 DEG  C. by furnace 8, and then (b) a silica tube 9 containing "Hopcalite" (MnO2 + CnO) at 240 DEG  C.  Thus residual H2 is oxidized to water vapour and CO to CO2, which are removed in the second molecular sieves 10 and 11, which contain Linde type 5a. Unit 10 is at room temperature, unit 11 is at - 196 DEG  C.  The emergent gases now pass through metal gettering means 13 which contains lithium vapour to remove the last traces of O2 and N2, and finally molecular sieve 15 (identical with 11).  The apparatus may be operated at a pressure of 5-10 p.s.i.

A device for measuring the relative position of two parts of a machine tool comprises a rigid beam 1 to be mounted on one part and a measuring head 3 moving with the other part movable along the beam, the head having means for scanning an optical grating 11 carried on the beam to provide an electrical output indicating the position of the head within one of a number of short distances (e.g. 1 inch) along the beam and a rotary transducer driven through a pinion from a rack 21 on the beam giving a coarse indication of the position. The grating 11 is mounted over a window 9 in the beam and is scanned by light from lamp 13 and lens 15. The grating has three zones, each sensed by four photo-cells 17. The grating may be reflective instead of transmissive, and formed on the beam itself. Rack 21 drives a rotary encoder giving a decimal indication of each 0À1 inch of travel up to one inch, another encoder indicating inches of travel, and a third encoder indicates tens of inches.

Abstract: 991,573. Fluid-pressure servomotor control systems. BRISTOL PNEUMATIC TOOLS Ltd. June 11, 1963 [June 21,1962], No. 23922/62. Heading G3P. The output of a two-stage compressor A is regulated in accordance with the pressure in a storage receiver B by controlling the speed of the pine mover which drives the compressor to maintain a substantial constant pressure in the receiver. The receiver is connected by conduit 7 whereby the pressure acts on a diaphragm 11 to position a valve controlling the supply of fluid to a chamber 14. The pressure in the chamber 14 positions a spring loaded piston 15 to position a rod 18 connected to a throttle lever or governor. A fined orifice 19 allows leakage from the chamber 14. The receiver B is also connected to a control valve 28 of a conventional unloader device acting on the compressor inlet valve 30. The valve 28 also controls the supply of fluid to chamber 14 through a non-return valve 32 to provide a low speed limit by moving the piston against a stop 33. The piston 15 carries a rolling sealing diaphragm 16.

IPC: F04B39/08
Filed: 1919-10-01
Abstract: 149,544. Brusa, R. Oct. 1, 1919. Percussive hand tools; percussive drills; dressing by percussion.-An air compressor for effecting alternate increase and release of pressure for the operation of drills, hammers, &c., comprises a cylinder with a single valve operated, in synchronism with the piston, from the driving shaft; the motion of the tool uncovers an aperture for release of the compressed air at the end of the stroke. The use of the apparatus for perforating and engraving marble, granite, &c., drilling blast holes, grooving and picking flagstones &c., is mentioned. Fig. 1 shows a compressor in which inlet of air takes place through apertures 14 and passed a valve 6 normally raised by a spring 13. The valve is actuated by a lever 7 driven from an eccentric 9 on the shaft, and the air is driven out to the tool through an union 10. Two or more air pipes 11, Fig. 8, may be connected to the union each supplying the cylinders E of a tool, the compressor A being mounted, along with an electric motor C driving it, on a three wheeled carriage, the handle of which carries a switch D. The tools are resiliently fixed in the carriage, in the stone dressing apparatus shown, but for drilling blast holes &c. may be connected with it by a hose. Each tool carries a piston 16 working in the cylinder, which, in its outermost position uncovers the seat of a spring pressed valve 17, or a simple aperture whereby air is released. The return stroke of the compressor piston creates a vacuum which retracts the tool piston being assisted by the admission of air through an aperture 20. A hand operated valve 21 regulates the force of the blow by controlling the amount of air passing through. Recoil is prevented by the position of the inlet from the pipe 11 to the tool cylinder, and by the turning of the compressor valve.
