Title: Method and apparatus for cutting work pieces by a beam of charge carriers
IPC: B23K15/08
Filed: 1961-08-01
Abstract: 922,917. Electron or heavy-ion beam apparatus. CARL ZEISS-STIFTUNG, [trading as CARL ZEISS [firm of]]. Aug. 1 1961 [March 8, 1961], No. 27799/61 Class 39(1). [Also in Groups XXII and XXIII] A workpiece 26 is cut by a focused beam 25 of charged particles of sufficient intensity to penetrate through the workpiece and melt the material thereof and eject the molten material in the direction of the beam, the beam and workpiece having relative movement transversely of the beam. A pulsating electron beam is generated by a cathode 1, control electrode 2 and grounded anode 3 supplied from a high voltage source 4 through device 5 comprising an adjustable heating source 6, control pulse source 7 and adjustable bias voltage 8. The beam passes through a grounded tube 15 and a diaphragm 9 having vertical and transverse adjustment by knobs 10, 11 and is focused by an electromagnetic lens 20 fed by adjustable source 43. Devices 23, 27 fed by generators 21, 22 are provided to deflect the beam whilst retaining it parallel. The workpiece 26 which may be of glass, ferrite, ceramic, carbided grinding material, cemented carbides, sintered oxides, steel such as nickel-chrome steel, copper or silver is mounted on a table 30 movable in two horizontal directions by motors such as 31 controlled by a programming device 32 which may include templates; the workpiece may also be turned. For cutting sinusoidal or zig-zag lines, the workpiece may be moved in one direction whilst the beam is deflected in a perpendicular direction. For optimum cutting the beam is focused to provide its point of smallest cross-section just above the surface of the workpiece. A chamber 24 lined with lead plates to prevent radiation has an observation window 28. The apparatus also includes an optical viewing system comprising a light source 12, directed on to the workpiece by prisms 13, 14 and lens 17 having a replaceable glass plate 18, and which is reflected through a mirror 16 and window 50 of X-ray protective glass into a stereo-microscope 49; the lens 17 is adjustable by a knob 19. An example is given for cutting a spiral spring from a cylinder of spring steel, Fig. 4 (not shown). An ion beam may be used instead of an electron beam.

Title: Article-conveying apparatus
IPC: B30B15/30
Filed: 1973-06-12
Abstract: 1421413 Transferring articles between conveyers O PISONI 12 June 1973 [13 June 1972] 27917/73 Heading B8A Blocks 13 of soap on a conveyer 14, to be transferred to individual carriers 9 of a conveyer 8, are successively brought into contact with an abutment 16, rebound from which is prevented by a suction device 17. At the same time each soap block operates a switch 18. This activates at arm 20 which then moves from a position A (broken lines, Fig. 1) through position B, to sweep the soap block up an arcuate guide 22. The latter is moved from the broken line position to the full line position (Fig. 1). The guide 22 leads the blocks into one of a pair of guideways 19 carried by a rotating housing 5. Centrifugal force propels the blocks outwardly along the guides 19 and into respective carriers 9 of the conveyer 8. When the machine is being adjusted and therefore is being run too slowly for centrifugal force to provide the transfer force, a pusher 25 operated by a linkage 26 from a cam 10, is used to propel the soap blocks 13 along the guides 19. Movement of the pusher 20 is derived from a cam 11, and movement of the guide 22 is generated by a cam 12. Rotation of the housing 5 is synchronized with the conveyer 8, by the action of a gear ring 7 on the housing which engages the traction chain of the conveyer 8.

Title: Improvements in or relating to television transmitting and receiving systems
IPC: H04N3/34
Filed: 1937-10-14
Abstract: 503,555. Television. BLUMLEIN, A. D. Oct. 14, 1937, No. 27929. [Class 40 (iii)] In addition to the normal movements of a scanning spot, a further component of motion is so imparted that the spot oscillates about the axis 4, 5, 6 of a scanning line 1, 2, 3 and thus increases the detail of the transmitted image. Synchronizing signals are transmitted to synchronize the oscillations of the reproducing spot with those of the spot at the transmitter. The signals are transmitted on a sub-carrier or as phase or frequency modulations of the vision signals. In the latter case, the synchronizing signals are derived at the receiver by an amplitude limiter, followed by a resonant circuit, sharply tuned off the carrier frequency, and a demodulator. The diameter of the spot is less than the width of the line effectively scanned and the amplitude of the oscillations is one half the distance between the axes of the lines. The oscillation is effected by superimposing sinusoidal or other oscillations on the framefrequency oscillations. When interlaced scanning is used, the amplitude of the additional oscillation is between two-thirds and one-and a-half times the distance between the axes of the lines.

Title: Article conveyor
IPC: B65G17/12
Filed: 1973-06-12
Abstract: 1408220 Chain conveyer J M LEACH 12 June 1973 27935/73 Heading B8A Articles are transferred from one level to another on platforms formed by two chain lengths the links of which are connected transversely by rods, the platforms being supported and transported on two pairs of chains. The links of the chains forming the platforms are alternately inner links which are flat and elongated and outer links which are of inverted U-shape and support a body member having a bore to receive a rod extending almost therethrough transversely of the link, thus defining a flange, and gusset ribs extending from the sides of the body member to a plate on the base of the U-shaped portion. Fig. 2 shows articles A being raised from an upstream conveyer, Fig. 1 (not shown) to a downstream conveyer 124 at a higher level. Each article is supported on a platform 30 comprising two lengths of chain interconnected by rods, which platform is flexible in one direction to enable it to pass round sprockets 22 on the return run while being inflexible under load. Fig. 7 shows the construction of the chain lengths. Inner links 46 are connected to outer links 48 by pins 52, the base of the inverted U-shape of link 48 extending past the connection to prevent flexing in a downward direction. Body member 49 has a bore extending transversely almost therethrough and gusset ribs 57 add strength. The articles A are fed to the conveyer such that each article fits neatly on to a platform. In Fig. 1 (not shown), a driven chain carrying pusher members moves faster than a pair of chains supporting the articles so that the articles are spaced by at least the distance between platforms, while articles arriving slightly too late to be engaged by a particular pusher are overtaken by that pusher and engaged by the next following one, leaving a gap and consequently an empty platform.

Title: Concentrating salt solutions by evaporation and freezing
IPC: C01D3/06
Filed: 1954-09-28
Abstract: <PICT:0793189/III/1> Salt solution, e.g. sea water or underground saline solution, is concentrated by subjecting the solution to reduced pressure by means of a vacuum pump which discharges into a jet condenser maintained at a temperature below 5 DEG  C., whereby part of the water is evaporated from the solution and part is frozen out as ice, the evaporation being effected in a chamber having a vertical flow-down pipe containing a column of the solution with a height corresponding to atmospheric pressure.  Evaporation chamber 1 has a flow-down pipe 2 extending into tank 3, and is connected to vacuum pump 6 via vapour-freezer 7.  The pump discharges into jet condenser 9 which is supplied with cold water through pipe 22. The condenser has a flow-down pipe 11 extending into tank 12. Chamber 1 is at least 10.33 metres above the brine level in tank 3; and condenser 10 is at least 10.33 metres above the water level in tank 12.  Sea water from tank 4 is supplied to chamber 1, and then valve 29 is closed.  Some of the water evaporates in chamber 1, and a mixture of brine and ice collects in tank 3.  The brine is recirculated by pump 25 from the bottom of tank 3 to chamber 1. Some of the water-vapour withdrawn from chamber 1 is condensed to ice in freezer 7; and a mixture of air and water vapour is sucked into pump 6, and then discharged into condenser 9.  A pressure of about 1 mm. Hg. is maintained in chamber 1; and there is a pressure gradient of about 3.5 mm. across pump 6.  Ice is discharged from freezer 7 into tank 23; and ice from tank 3 is collected in tank 20.  The ice melts in tanks 20 and 23; and the cold water is pumped to the condenser through pipe 22.  Air is withdrawn from the condenser by ejector 13 which is operated by water pumped up from tank 12.  When the brine has become sufficiently concentrated, it is withdrawn from the system via pipe 27.
