Title: Improvements in or relating to sheet feeding apparatus
IPC: B65H5/24
Filed: 1965-06-25
Abstract: 1,103,293. Feeding sheets. HARRIS-INTERTYPE CORPORATION. 25 June, 1965 [1 July, 1964], No. 27127/65. Heading B6B. Sheets are fed sequentially from the top of a pile 28 on to a table 20, and conveyed along the table in underlapped fashion by pairs of grippers 38 on endless chains 35 to engage rising and falling register stops 45, and are then fed to the grippers 15 of the cylinder 10 of a printing press by suction belts 55 which accelerate the sheets to engage stops on the cylinder. Since a sheet being registered by the stops 45 is covered by the trailing portion of the preceding sheet fed by the grippers 15 of the cylinder, disturbance of the registered sheet is prevented by hook portions 48 on the stops 45, Figs. 2 and 3 (not shown). When the sheets are front-registered, a known side register mechanism 25 becomes operative. Arms 22 on a cross-shaft serve to guide the sheets towards the cylinder 10. The suction conveyer means comprises a box-like member 50, Figs. 2-7 (not shown), extending along an aperture in the table 20 between the side register support plate 24 and the stops 45, which is connected by pipe 100 to a three-way valve 102. The valve 102 is operated automatically to connect, alternately, the box 50 to sources of vacuum and compressed air, or to neither. In one form (Figs. 1-9), the box 50 is covered by non- continuous perforated belts 55 which have one end fastened to a roller 60 and the other to a take-up roller 65, and they are guided over the box 50 by a roller 61. The belts are fed in the direction of sheet feed from rest up to the speed of the grippers 15 of the cylinder 10, and then in the reverse direction, by a cam-operated arm 80 having a toothed rack 78 which drives gearing 72-76 connected to the shaft 68 on which the roller 86 is secured. The shaft 68 is connected by gearing to the shaft 88 of the roller 65 through a lost-motion clutch (Fig. 8), which compensates for the overlapping of the belts 55 on the rollers 60, 65. In a modification, Figs. 10 and 11 (not shown), the suction belts 55 are replaced by endless belts 105, and include arrangements, such as a pin-feed or timing belts for ensuring correct belt feed. These belts can be driven unidirectionally through a one-way clutch, or can be driven first in one direction, and then in the reverse direction. The periods when compressed air is established at the box 50 and perforated belts 55 or 105 causes quick release of the sheets by the belts, and tends to float the sheet over the belts when the grippers 15 are operative on the sheets.

Title: Dehydrogenation process
Inventor: JOHNSON PETER
IPC: B01J23/80
Filed: 1965-06-30
Abstract: Preparation of an aldehyde or ketone by the dehydrogenation of the corresponding primary or secondary alcohol respectively by contacting the alcohol at elevated temperature with a catalyst comprising elemental nickel and zinc oxide.  Suitable feed alcohols include isopropanol, n- or sec-butanol, sec-pentanol or n- or sec-hexanol. The dehydrogenation catalyst, which may be supported on an inert material such as kieselguhr or pumice, preferably has a weight ratio of Ni to Zn in the range 1:100 to 10:1 and may be prepared by roasting a suitable support material, cooling it, then mixing the cooled support with an aqueous slurry formed from a nickel salt and zinc oxide, drying the mixture, roasting the residue in air or oxygen and, finally, heating (e.g. to 300 DEG  to 400 DEG  C.) in a stream of hydrogen.  The dehydrogenation is preferably carried out at 250 DEG  to 450 DEG  C. by passing the feed alcohol in the vapour phase over the catalyst optionally in a stream of carrier gas such as hydrogen.  The preparation of hexanones from sec-hexanols using a catalyst containing 2.3% Ni and 5.5% Zn is described.  Comparative examples describe the use of catalysts containing copper and zinc oxide and copper and magnesium oxide.ALSO:A catalyst, suitable for dehydrogenating alcohols, comprising p  elemental nickel and zinc oxide, preferably having a weight ratio of Ni to Zn in the range 1:100 to 10:1 and a combined weight of nickel and zinc oxide representing 0.1 to 98% by weight of the total catalyst, is prepared by roasting a suitable support material (e.g. pumice or kieselguhr), cooling the support material, mixing the cooled support material with a aqueous slurry formed from the nickel salt (e.g. nickel formate) and zinc oxide, drying the mixture, roasting the residue in a stream of air or oxygen and, finally, heating in a stream of hydrogen.  The slurried catalyst composition is preferably dried at a temperature between 80 DEG  and 150 DEG C., roasted in air at a temperature between 350 DEG  and 450 DEG C. and reduced at a temperature between 300 DEG  and 400 DEG C.  The example described the preparation of a catalyst containing 2.3% nickel and 5.5% zinc by weight wherein 10-18 mesh pumice is roasted at 550 DEG C., cooled in vacuo, mixed with a slurry containing nickel formate zinc oxide and aqueous ammonia, dried and roasted in air and reduced with hydrogen prior to use. Catalysts containing 7.3% Cu and 12.6% Zn, and 7.5% Cu and 13.5% Mg are prepared by a similar method for comparison.

Title: Arrangement for generating a series of digital signals
IPC: H04L9/24
Filed: 1970-06-08
Abstract: 1278346 Cyphering systems TELEFONAKTIEBOLAGET L M ERICSSON 8 June 1970 [11 June 1969] 27709/70 Heading H4P An encyphering system comprisse a matrix of switches in which the switches have a onecondition and a zero-condition, with stepping pulse generators arranged to select the switches repeatedly in pseudo-random manner to define by their condition a series of digital signals, and a number of pulse generators equal to half the number of switches which generators are arranged to generate respective pseudo-random series of binary ones and zeros and have two outlets each, these outlets being arranged so that the output signal of one outlet is inverted relatively to the output signal of the other outlet, the outlets being connected to respective switches of the matrix to control the condition thereof so that the number of switches with zero-condition will always be equal to the number of switches with one-condition. By this means, although the distribution is changed, the numbers of Os and is are always equal. The matrix of switches M comprises 16 AND gates a11-a44 connected to an output OR gate E. The matrix is stepped by generators X1, X2, Y1, Y2 each of which generates a pseudo random series of differing lengths, by means of say a feedback shift register of maximum length type, which are stepped by a clock KG having a frequency f1. Generators X1 &c. together produce a four digit binary number. A further pseudo random generator comprises pulse generators PG1-PG8 stepped at a frequency f2 feeding the third inlet of AND gates a11-a44 via a permuting network P which provides a selectable key combination. With switches SA, SB in their alternative positions, pulses from clock KG pass through a further pseudo-random generator having pulse generators PG11-PG13 stepped at a frequency f1 each producing a different pseudo random series and connected to AND gate O1 which will stop generators PG1-PG8 with an average frequency f1/8 with the interval between pulses varying at random, thus altering the content of matrix M similarly. In another embodiment each of pulse generators PG1-PG8 can be replaced separately by a flip-flop V1-V8 constituting successive stages of a shift register S which can be stepped by a frequency f3, for example the ciphered pulse train. The matrix in this case is fed through bi-stable flip-flops V11-V44 and switched via AND circuits 0-100 to 0-161. As an alternative to the outputs E being combined in an OR circuit to produce a single output U, a sub-group of switches may be selected simultaneously to operate for example a non-binary signal.
