Title: Electron Beam Apparatus.
IPC: H01J37/305
Filed: 1967-11-23
Abstract: 1,196,787. Electron beam furnaces. AIR REDUCTION CO. Inc. 23 Nov., 1967 [16 Dec., 1966; 3 May, 1967; 22 May, 1967; 11 Aug., 1967], No. 53318/67. Heading HD. An electron beam furnace utilizes a beam which is initially ribbon-shaped and is deflected in a magnetic field transverse to the plane of the ribbon to follow an arcuate path in the plane of the ribbon. The extent of the magnetic field is limited so that electrons at the outer edge of the beam are in the field longer than those at the inner edge and the beam is focused to a minimum cross-section. In Fig. 1 the gun 26 and the crucible 33 are on opposite sides of a wall 32 between an upper chamber 20 at a pressure of less than 10<SP>-2</SP> torr and a lower chamber 22 at a pressure of less than 10<SP>-4</SP> torr. The beam 25 is deflected by magnet 28 through a narrow opening 23 in the wall 32 and then by further perpendicular magnets 51, 52 on to a desired spot at the crucible 33. Metal or carbon plates define the opening 23 and are burnt through in the event of excessive divergence or inaccurate deflection of the beam. The electron gun 26 comprises one, or two, elongated emitters 27 disposed in recesses in a beam forming electrode and parallel elongated accelerating electrodes 46. A plurality of guns may be used for directing beams through a plurality of openings 23 arranged about the crucible 33. In Fig. 4 a single magnet 53 is employed and the furnace is not separated into two chambers. The magnet comprises separate pairs 60, 61, 62 of polepiece segments and the beam 25b is deflected and converged as shown. In Figs. 6 and 7 the magnet 63 comprises a pair of semicircular polepieces 65, 66 slanted towards and away from each other as shown to provide an inhomogenous field for producing a more convergent beam 25c. The polepieces may be connected to solenoids or permanent magnets. In Fig. 9 two separate pairs of polepieces 75, 77 are utilized for greater versatility . In the gun of Fig. 13 comprising an elongated emitter 27d and an accelerating electrode plate 46d having an elongated opening, the beam has an initial non- normal orientation due to the magnetic field of the emitter current and is then deflected in a transverse magnetic field established between a pair of bar shaped polepieces interconnected by electromagnets which may be independently energized to establish a suitable field gradient. The beam is longitudinally and laterally focused in the bowed out fringe field 91. In an alternative embodiment the magnetic field is established between a pair of flared polepieces interconnected by a single electromagnet (Fig. 17).

A reciprocatory tool, e.g. a filing tool, includes a drive shaft 2 which carries an inclined rotatably. mounted crank-pin 5 to which there is attached at right angles a coupling pin 7; the coupling pin passes slidably through a swivel mounted bearing eye 8 disposed at the lower end of a bolt 9 which is attached in a radially offset position to the reciprocable part of the tool gripping head 11. Rotation of the shaft 2 reciprocates the bolt 9 and thereby the tool. The head 11 is angularly adjustable about its axis which is offset from that of the shaft 2 to effect relative displacement of the bearing eye along the coupling pin 7 with respect to the axis of the shaft 2, thereby adjusting the length of reciprocatory stroke. A detent 13 acts to retain the head 11 in adjusted positions. The tool may be powered by an electric, or, as shown, pneumatic motor 3 having a speed control knob 12.

Arm 3 is attached to sleeves 9, 10, Figs. 8, 9, rotatable on leg 2, sleeve 9 having a helical slot 15 and leg 2 having a vertical slot 16, a pin 17 extending through both slots. The pin 17 is driven vertically by a tie rod 20 connected to a mechanism for extending the table framework and causes rotation of sleeves 9, 10 and thus arcuate movement of arm 3 and seat 5. Seat 5 is fixed to a tubular member 4 on arm 3, and a connecting piece 14, Fig. 11, is connected at one end to leg 2 and has its other end passing through a longitudinal slot 12 in arm 3 and a' circumferential slot 13 in member 4. Thus, as arm 3 moves in an arc during folding, member 4 and arm 3 move axially and member 4 rotates on arm 3 causing seat 5 to tip over into a vertical position. A leg 6 for the seat 5 has a pin 7 passing through a helical slot 19 in member 4 and a hinged backrest 8 is connected to the leg 6 by a tie bar 123 so that during folding the leg 6 rotates relative to seat 5 and the backrest 8 is folded downwardly on to seat 5. The framework shown comprises cross-members 21 joined by telescopic side members 11. In an alternative arrangement Figs. 14-19, (not shown), the cross-members 21 are joined by articulated scissor members (27).

Abstract: 1366176 Tilting cabs APPLIED POWER INDUSTRIES Inc 29 Nov 1972 [10 Dec 1971] 55172/72 Heading B7B A vehicle cab 14 is tiltable about an axis 12 by means of an hydraulic ram 16, 18 which is supplied from a pump 38 via a change over valve 30, the ram return line 52 including valve means 54, (70) (Fig. 2, not shown) which restricts flow from the ram when the flow rate or pressure in line 52 reaches a predetermined value, this arrangement preventing free fall of the cab as it passes through the over centre axis 68. In raising the cab fluid passes via lines 46, 40 and 32 to ram chamber 22 and from ram chamber 24 via lines 34 and 52 to the reservoir 48. As the cab passes through the axis 68 its weight acts to pull the ram piston 18 from cylinder 16, and the flow rate in lines 34 and 52 increases. A spring loaded ball 60 in line 52 seats to close the line when the flow velocity therein reaches a predetermined value, and the return flow is bypassed through a fixed area restricted orifice 66 in a line 64. In another embodiment (Fig. 2, not shown) the valve 54 is replaced by a valve which closes when the pressure in the return line exceeds a predetermined minimum.

The flexible cover 15 is attached to the container 10 by projecting rods 18 which locate in holes 20 and the sides 16 may be glued to container side walls 17. Strips 22 of the cover material which fix the rods 18 in place also form individual pockets accessible by means of zip fasteners 21. The container 10 has ribs and grooves 13 to provide increased rigidity and a rod 25 is attached to the container wall by brackets 24 one of which also receives removable wheel-mounting assemblies 32. This bracket 24 carries exteriorly threaded bosses 28 each having therein a transverse peg (30) (Fig. 2, not shown) which co-operates with a groove 33 in the end of the wheel mounts 32 to prevent relative rotation of these parts. A nut (38) having an internal shoulder is screwed on the boss 28 and the shoulder abuts a circlip (34) on the mounts 32 to attach the wheels to the boss 28 and bracket 24. The tube 25 receives a telescopic handle 26 and a wire-framed cover 45 is pivotally mounted in holes 48 to act as a rain-shield. The rigid part 10 of the container may be of moulded fibre glass or plastics such as ABS.
