Title: Method and apparatus for vibratory cutting
IPC: B24B1/04
Filed: 1967-08-11
Abstract: 1,135,886. Abrading. INTERNATIONAL BUSINESS MACHINES CORP. 11 Aug., 1967 [26 Sept., 1966], No. 36882/67. Heading B3D. A method for vibratory cutting a workpiece comprises providing a tool with a work tip of material harder than the workpiece to be operated upon, mounting a workpiece in working relationship with the tip, introducing abrasive particles between the tip and workpiece, which particles are harder than the workpiece but not harder than the tip, and effecting vibration between the tip and workpiece. The tool may be of diamond, silicon carbide, sintered ceramic, cubic boron nitride or similar hard material, and the abrasive particles be of diamond, aluminium oxide, corundum, boron carbide, silicon carbide or the like for operating on a workpiece of hard material such as quartz, glass, titanium, tungsten carbide, sapphire, stone or the like. The tool tip 22 may be secured to a tool vibrated by piezo-electric or magnetostrictive means and the abrasive particles supplied in a fluid, such as water, to machine the workpiece 24. The tool tip may comprise a whole stone diamond oriented so that its hardest face is presented to the workpiece which may consist of a similar diamond oriented so that a less hard face is engaged by the tool, the abrasive particles also consisting of similar diamonds. The tool may consist of several whole stone diamonds for machining a pattern on the workpiece. The abrasive particles may be continuously circulated by a pump to the workpiece so that as they are reduced in size, the finish produced by the machine is smoother, or fresh particles may be continuously supplied. Either the workpiece or tool may be vibrated and relative linear or rotary movement may be effected between the tool and workpiece to produce slots or screwthreads. The workpiece may be of relatively soft material, such as mild steel, brass or copper and the tool tip of hard material and the abrasive particles harder than the workpieoe and not so hard or as hard at the tool tip. The method may be applied to forming diamond lenses, jewel bearings for watches, needles, dies for wire drawing, filament spinning and extruding, for cutting grooves, indentations and gear teeth, machining semi-conductor material and diffraction gratings.

Patent GB-907379-A (GB)
Title: Improvements in or relating to pulse echo-sounding apparatus
IPC: G01S15/96
Filed: 1958-11-17
Abstract: 907,379. Echo-sounding. ELECTROACUSTIC G.m.b.H. Nov. 17, 1958 [Nov. 15, 1957], No. 36907/58. Class 40 (7). In a marine echo-sounder the vertical sounding receiver is blocked for a predetermined period on receipt of the sea bottom echo; confusion by further echoes and undesired blackening of spark-discharge recording paper are thus avoided and the period is used for indicating echoes from horizontal soundings. Pulses from generator 2 excite vertical and horizontal sounding electro-acoustic transducers 3, 4 whose echo outputs are fed to corresponding receivers 5, 6. Valve 18 of a bi-stable multivibrator conducts when the bias 10 imposed on diode 11 is overcome by the transmitted pulse application to terminals 22, 23; the ensuing voltage across resistor 20 renders vertical sounding receiver 5 operative. When the sea bottom echo pulse arrives at terminals 8, 9 from receiver 5 the bias on diode 11<SP>1</SP> is overcome and valve 19 of the multivibrator conducts, thus cutting off valve 18 and hence blocking receiver 5, and opening horizontal sounding receiver 6. The echo indicator may be a cathode-ray tube or glow discharge lamp.

Title: Improvements in or relating to punching devices
IPC: G06K1/02
Filed: 1965-09-03
Abstract: 1,086,598. Selective punching devices. PHILIPS GLOEILAMPENFABRIEKEN N.V. Sept. 3, 1965 [Sept. 8, 1964], No. 37701/65. Heading B4B. [Also in Division H1] A device for punching a hole or combinations of holes in a stepwise moved record carrier by means of relative movement between a punch matrix and adjustable punching tools is characterized in that the relative movement is effected by an electromagnet the energization of which is controlled by electric current pulses and in that the punch matrix is secured to the magnet armature while the latter is retained in a rest condition. As shown, a matrix 6 is arranged on the armature 4 of an electromagnet 2 which is secured in a frame 1, the armature being suspended from a plate spring 5. The electromagnet is provided with a coil 3 on which a holding winding and a driving winding are arranged. When the holding winding is switched on, the armature is pulled downwards into its equilibrium position and the spring tensioned. The selected punches are brought into the operating condition by energizing the corresponding magnets 10. For punching, the magnet is switched off very rapidly. As the result of the energy stored in the spring, the armature moves upwards as a freely oscillating mass. After approximately half a stroke, the punches locked by the magnets 10 perforate the tape 9. After the return stroke, the armature is again held by the magnet 2 which is energized when the equilibrium position is approached. In an alternative arrangement, the armature for punching the tape is attracted by the magnet 2; in this case, the spring supplies the restoring force. When the armature is moved by the alternate energization of two oppositely-located magnets, the spring may be omitted. The magnet may be switched on after punching and, at the latest, during the return stroke; in this case, the armature performs forced oscillations. In another embodiment, the magnet may be controlled in accordance with the amplitude and the energy consumed by punching; in this case, the armature oscillates continuously.

Title: Process for the recovery of hydrogen from industrial gases
Inventor: HARMENS ALEXANDER
IPC: F25J3/06
Filed: 1963-09-26
Abstract: Separation of hydrogen from coke oven gas is effected by forcing feed mixture by compressor 3 through heat exchangers 5, 6, 8 and 9, thereby effecting partial liquefaction, passing the wet feed gas into a phase separator 11 and then passing the unliquefied crude hydrogen into a column 17 where it is washed with liquid natural hydrocarbon gas forced by a pump 13 through heat exchangers 12, 16 to effect subcooling prior to entry into column 17 from the head of which hydrogen is withdrawn.  The mixture of liquid natural gas and most of the nitrogen content of the feed mixture is withdrawn from the base of column 17 and is added to the liquid (mostly methane) from separator 11 and after expansion in a valve 22 is used to cool exchanger 9 thereby being in part vaporized.  Hydrogen withdrawn from the <PICT:0975628/C1/1> head of column 17 is expanded in a turbine 19 and any solid methane particles are removed by a cyclone 7a which is periodically switched with a cyclone 7 which removes solid carbon dioxide particles produced in exchanger 6 and the sopurified cold hydrogen is warmed in exchangers 5, 6 before being discharged as product.

Title: Improvements in the manufacture and production of ethyl ether
IPC: C07C43/06
Filed: 1930-12-18
Abstract: Ethyl ether is manufactured by passing a vaporous mixture of ethylene, or gases containing it, and water vapour at a temperature below 300 DEG  C., preferably below 250 DEG  C., and at a pressure above 10, preferably above 20 atmospheres, over dehydration catalysts consisting of inorganic or organic acids or anhydrides which are difficultly volatile at the reaction temperatures, in a state of fine distribution on carriers, or phosphates of the rare earth metals. The activity of the catalysts may be improved by the addition of strongly dehydrating substances, e.g. oxides of metals of group 2 of the periodic system, especially zinc oxide, or anhydrous zinc chloride, alums, or phosphates of the alkali or alkaline-earth metals.  The amount of water vapour should not exceed 25 per cent by volume of the ethylene.  In examples, (1) a mixture of ethylene and water vapour is passed at 200 DEG  C. and 125 atmospheres pressure over active carbon laden with phosphorus pentoxide and phosphoric acid; (2) cerium metaphosphate is used as catalyst, the conditions being as in (1); (3) a mixture of ethylene and nitrogen is treated as in (1); (4) a mixture of ethylene and water vapour is passed over active carbon charged with phosphoric acid in a tube lined with copper or silver, the conditions being as in (1); (5) a mixture of ethylene and water vapour is passed at 210 DEG  C. and 125 atmospheres pressure over the catalyst of (4).  In each example ethyl ether and some ethyl alcohol are produced.  Other catalysts specified are sulphuric acid and sulphonic acids such as benzene sulphonic acid.  Specification 238,900, [Class 2 (iii), Dyes &c.], is referred to.

Title: Improvements in or relating to steering mechanism
IPC: B64C25/50
Filed: 1956-12-17
Abstract: 812,589. Vehicle power steering. CLEVELAND PNEUMATIC TOOL CO. Dec. 17, 1956 [March 15, 1956], No. 38388/56. Class 79(5) Ground steering mechanism for an aircraft landing gear having a pair of members 10, 13 capable of relative rotation, to one of which the steerable portion 11 of the landing gear is attached, comprises a cam 37 fixed to the member 13 and provided with a plurality of spaced ramp surfaces inclined in a manner whereby pressure applied successively to them causes rotation of the mmber 13, a plurality of motors 16 mounted on the other member 10 and each including a movable element carrying a cam follower 54 adapted to exert the pressure on the ramp surfaces, and control means operated by rotation of the member 13 to actuate the motors successively as each ramp surface moves into the path of the corresponding follower. In the example the member 13 comprises a collar which is connected by torque arms 14 to a telescoping member 11 carrying the aircraft wheels 12. The cam 37 is provided with six lobes 42 and each cam follower 54 is mounted on a shaft 53 supported by projections 52 provided on a piston 33 in a cylinder 34. The shafts 53 carry bearings 56 co-operating with guide slots 51. The control means comprises a distributor Valve assembly 80 having a rotor 64 which in the example is rotated in the same direction as the cam 37 and at six times the speed, the rotor 64 and cam 37 being drivingly connected through gearing, part of which is shown at 81, 39. Fig. 7a shows the connections between the cylinders 24a, b, c, distributor valve 80 and pump P with a control valve V for clockwise rotation of the cam 37. The pump P is connected through a pressure line 66, valve chamber 65 and valve port 72a to the cylinder 34a. The cylinder 34b is in a change-over condition and is cut off by a land 74 on the valve rotor 64. Cylinder 34c is connected through a port 72c, valve chamber 70 and pressure line 67 to a reservoir 81. Counter clockwise rotation of the cam 37 is effected by reversing the valve V so that the pressure line 66 is connected to the reservoir 81 and the pressure line 67 to the pump P. A pressure sensitive relief valve R maintains a back pressure in the line connecting the valve V to the reservoir 81, thereby producing a back pressure in the cylinder 34 connected to the reservoir so that free play is automatically taken up. The valve V is so arranged that when steering is not required the pressure lines 66, 67 are connected together. The pressure lines 66, 67 preferably include flow restricting orifices 82, 83 which serve to dampen shimmying of the wheels 12. The operative surfaces of the cam 37 are so designed as. to produce a constant torque steering mechanism. The number of cam lobes 42, cylinders 34 and the height of the cam lobes may be varied from that shown, and the cylinders may be circumerentially spaced so as to engage spaced lobes rather than surfaces on adjacent lobes. The mechanism may provide full 360 degrees steering.
