Title: Improvements relating to sheet folding machines
Inventor: BUSS BENJAMIN ALVIN
IPC: D06F89/00
Filed: 1958-09-16
Abstract: 905,910. Folding fabrics. AMETEK Inc. Sept. 16, 1958, No. 21906/62. Divided out of 905,908. Class 42 (2). A folding machine comprises first and second roll means with corresponding air blast means arranged opposite thereto so that operation of the air blast means causes a sheet passing between the rolls and the air blast means to be folded; means for conveying a folded sheet from the first rolls past the second rolls; measuring means for controlling the sequential operation of the air blast means in accordance with the length of the sheet being folded; preselection means for selectively operating the second air blast means so that a sheet passing between the second roll means and corresponding air blast means is folded again or so that the second air blast means is in operation before the leading edge of the folded sheet reaches the second air blast means and the sheet is not folded thereby. As shown, the invention is applied to the folding machine described in Specification 905,909. The preselection means is in the form of a switch 75 such that when it is in its closed position an impulse or signal fed by the timing mechanism to solenoid 25 to operate the blast means 24 of the first folding means 23, will also operate solenoid 76 to move switch 110 from its upper position to its lower position and thus complete a circuit to operate the air blast at 29 so that when the folded end of the sheet reaches this point it is blown direct into the rolls 32, 33 without being further folded. The arrangement is also such that the impulse or signal which would normally have operated the air blast 29 for a second fold is used to return the switch 110 to its upper position thus de-energizing solenoid 31 to stop the air blast at 29. With the switch 75 in its open position both folding means 23 and 29 produce folds in timed sequence so that a sheet passing through is folded twice. Specification 905,907 also is referred to.

Title: Improvements in or relating to Corpuscular Beam Apparatus
Inventor: HANSSEN KARL-JOSEF
IPC: H01J37/26
Filed: 1967-05-11
Abstract: 1,194,021. Electron microscopes. K. J. HANSSEN. 11 May, 1967 [13 May, 1966], No. 21907/67. Heading H1D. An electron microscope which includes an aberration-producing objective lens is used to produce high-contrast reproductions of phasecharacter or amplitude-character objects by first making a photographic recording of a first image obtained at a first value of excitation of the lens and with a first zone plate introduced into the beam path which allows, at that excitation value, only those spatial frequencies reproduced with positive (or negative) contrast to reach the image plane, and subsequently removing the first zone plate and making a second photographic recording at a second lens excitation value and using a second zone plate which similarly allows, at the second excitation value, only those spatial frequencies reproduced with positive (or negative) contrast to reach the image plane. The second excitation value is so selected that the associated lens aberration ensures that spatial frequencies are reproduced which were suppressed by the first zone plate, the final high-contrast image being obtained by the superposition of the two recordings e.g. by recording both images on the same film. By the use in succession of a sufficient number of different zone plates and corresponding lens excitation values, and the superimposition of the resulting images, all the positive (or negative) contrast spatial frequencies missing from the first image may be reproduced in the final image.
