Title: Charged particle beam scanning apparatus
Inventor: NIXON WILLIAM CHARLES
IPC: H01J37/28
Filed: 1990-09-14
Abstract: Scanning electron microscope apparatus adapted to display two views of a surface for stereoscopic viewing, wherein two series of electrical signals are obtained by scanning the surface with a normal and then tilted beam characterised by a frame store 36 to which the two series of electrical signals are supplied, the frame store including a feedback loop and input and feedback multiplying means 38, 40 and forming a recursive filter, and signal converter means 42 including an R G B look-up table memory means for generating R, G and B signals for display by a colour monitor 44. Alternate tilting of the beam is achieved by adjusting during alternate scans the currents flowing in the gun alignment coils 12 of the SEM so as to shift the beam, and simultaneously introducing an offset in the signals applied to at least one other element in the beam forming and focussing assembly, to counteract the shift introduced by the alignment adjustment, whereby the point of intersection of the beam axes follows the focal plane as focus is altered. The two video signals may be correlated to produce a correlation signal whose value for each point in the surface indicates the apparent shift in position of that point as between the normal and tilted beam scans, to produce a signal indicative of the surface topography. The correlating signal may be converted to a focussing control signal and may be enhanced by a process of successive approximations. <IMAGE>
Patent GB-908622-A (GB)
Abstract: 908,622. Healds. WITHNELL Ltd., J. B. Nov. 14, 1958 [Feb. 19, 1958], No. 5332/58. Class 142 (2). Healds consisting of two loops, one of which is tied to form an eye and the other of which passes through the eye, are made of round nylon monofil on the same machine as is used for making cotton healds. The tension applied is much greater than would be used for cotton, and the monofil is lubricated by paraffin wax to reduce friction as it passes through the machine. After the healds are assembled on the shaft, solvent and heat is applied, under tension, to cause the interengaging loops to adhere.

IPC: D05B3/14
Filed: 1991-11-28
Abstract: In a button-holder for a button-sewing machine, two clamp parts (8, 9) for the button (7) are guided in a parallel guide holder (28) so as to be movable by a first pneumatic cylinder (34) in opposite directions to clamp or release the button. The parallel guide holder (28) is swingable horizontally by a second pneumatic cylinder (17) to displace the clamp parts (8, 9) from the sewing position shown to a remote loading position. Thus, the button-holder does not require adjustment for different sized buttons and the button can be inserted away from the sewing region. The holder (28) is engaged in the sewing position by an adjustable stop to set the lateral spacing of the button from the sewing needle (6). The clamp parts (8, 9) are coupled within the holder (28) by a centrally pivoted link to give them opposite motions. <IMAGE>
Patent GB-919619-A (GB)
Abstract: 919,619. Stacking sheets. UNIVERSAL CORRUGATED BOX MACHINERY CORPORATION. Dec. 19, 1960 [March 18, 1960], No. 43601/60. Class 100 (1). A sheet stacking device comprises a normally stationary transfer conveyer 13, a feeding conveyer 11 having a discharge end and extending at right-angles to the transfer conveyer so as successively to discharge sheets thereon, means to interrupt discharge of sheets from the one conveyer to the other, a backstop 71 extending longitudinally of the conveyer 13 and spaced from the discharge end of the conveyer 11, the sheets abutting against the back-stop upon discharge on to the conveyer 13, and means which, when discharge of sheets on to the conveyer 13 is interrupted, move the back-stop to a retracted position and drive the conveyer 13 so as to move the stack of sheets thereon away from the discharge end of the conveyer 11 in a direction at right-angles to the direction of discharge on to the conveyer 13. The conveyer 13 has a frame comprising side and end beams 16, 17. Rollers 18 are rotatably mounted between the side beams 16 and may be driven in any suitable way. The conveyer 11 comprises endless belts which discharge sheets, received from a source such as a folding-machine, beneath a normally open gate 12, over a roller 22 and a backing plate 19 secured to one side-beam 16, on to the conveyer 13 where they abut against the back-stop 71. The back-stop 71 is a plate pivotally mounted at 66 on a beam 27 which longitudinally straddles the conveyer 13 and is secured at each end to a standard 24 mounted for horizontal movement along the end beams 17. Rotation of a crank 56 secured to a shaft 48 journalled in the standards 24 causes sprocket-wheels mounted in a housing 57 on each standard 24 to rotate and because the sprockets engage a chain 45 fixed to the corresponding beam 17 the whole assembly 24, 27, 71 is thereby moved across the conveyer 13 in order to adjust the spacing between the plate 19 and back-stop 71. Such spacing is so adjusted as to be slightly greater than the width of a sheet. The backstop 71 and plate 19 are notched along their lower edges at 72 and 20, respectively, to accommodate the rollers 18. A pneumatic cylinder 76 is mounted on a beam 28 which is parallel to the beam 27 and is also mounted between the standards 24. A piston within the cylinder has its rod connected by a link 77 to the back-stop 71 and may be actuated so as to pivot the back-stop to the broken-line position shown in Fig. 2. The back-stop is oscillated continuously between the broken- and full-line positions while sheets are being discharged on to the conveyer 13 and serves to align the edges L of the sheets. When the pile of sheets on the conveyer 13 reaches a predetermined height the gate 12 is closed, the back-stop is arrested in the broken-line position and the rollers 18 are driven so as to transport the pile to a receiving conveyer.
