Title: Improvements in or relating to apparatus for controlling a multi-colour rotary printing machine
Inventor: JOHNE ALBRECHT
IPC: B41F33/00
Filed: 1971-09-23
Abstract: 1294640 Controlling printing machines POLYGRAPH LEIPZIG KOMBINAT FUR OLYGRAPHISCHE MASCHINEN-UND AUSRUSTUNGEN VEB 23 Sept 1971 44425/71 Heading B6C A multi-colour sheet fed offset rotary printing machine is controlled by a device utilizing a shift register and interrogation units. In the machine shown a feeding cylinder 4, Fig. 1, passes a copy sheet 2 to the impression cylinder 5 of a first printing unit and then via a transfer cylinder 6 to an impression cylinder 5<SP>1</SP> of the following printing unit. During periods when no sheet is present between the offset cylinder 10 and the cylinder 5 displacement means associated with the first printing unit are operated to cause the inking rollers 8 to be separated from a plate cylinder 9, the cylinder 9 to be separated from the cylinder 10 and the cylinder 10 to be separated from the cylinder 5. At the moment when a sheet reaches the contact point between cylinders 5 and 10 both cylinders have to be placed into their respective operating positions and, prior to this movement of the cylinders, the inking rollers 8 have to be placed into contact with the cylinder 9 and the latter into contact with the cylinder 10. Then displacements of the individual cylinders in each printing unit are controlled independently of each other and independently of the corresponding displacements of cylinders in other printing units of the machine. The displacements of the cylinders in each of the individual printing units are, so controlled by apparatus embodying the invention that these displacements take place in a predetermined sequence. A block-schematic diagram of one such apparatus is shown in Fig. 2 and comprises a shift register 11, interrogation units 12 and a control checking unit 27 for reducing operating speed after the last sheet has passed through the printing machine.

Abstract: 1397710 Semi-conductor logic circuits TOKYO SHIBAURA ELECTRIC CO Ltd 28 Sept 1973 [30 Sept 1972 11 Nov 1972] 45519/73 Heading H3T A clocked F.E.T. logic circuit 10, Fig. 1, has its output level at 17 maintained at a definite 1 or 0 level by a feedback circuit 40. The output appears on capacitor C L  which is charged in # time by V ss  and F.E.T. 13 and discharged or not by T14, T15 depending upon A, B. Leakage across C L  and charge-sharing with stray C o  affects the output level, and the circuit 40 corrects this by two stages of inversion T23, T24 and T34, T35 during ## time, ## acting on T33, T36. T14, T15 in logic circuit 10 thus perform a NAND function, but may be alternatively part of a so-called read-only array of F.E.T. storage devices (Figs. 9, 12, not shown). T35, T35 in the second inverter may be omitted (Fig. 3, not shown) and instead of clocking either of the inverter stages themselves, a clocked series-gate may be incorporated (T52, T53, Fig. 4, not shown). The conductivity types and voltage polarities may be reversed (Fig. 5, not shown); and the circuits may be adapted to use only single conductivity type F.E.T.s (Figs. 10, 11, not shown) wherein a threshold-boosting pull-up capacitor (261) may be incorporated. The clock pulses (#1 Fig. 8, not shown) which activate the feedback circuit (Fig. 7, not shown), may have a delayed starting edge to permit the output (S) on C L , if slowed by circuit time constants, to reach a distinct level before the feedback operates.

In a supervisory system for two-way repeaters using different frequency bands for the two directions of transmission and in which repeater testing is carried out using two frequencies, or one frequency and the noise generated in the repeater, lying in the frequency band for one direction of transmission which, when modulated together, produce a difference frequency which lies in the frequency band for the other direction of transmission, the modulating circuit, units 10 to 13, Fig. 1, is connected, on the side of the repeater remote from the testing terminal station, between a pair of branching circuits so that the modulating circuit is isolated from W to E transmissions and faults in the modulating circuit have no effect on transmissions in either direction. Test signal transmission takes place via line 16, hybrid 9, line 14, hybrid 8, line 15, filter 10, amplifier 11, modulator 12, filter 13, hybrid 9, line 16 &c. The hybrid circuits 8 and 9 may comprise bridged-T networks as shown at 17 and 18, Fig. 3, the resonant circuits 20 and 21 being tuned to the test signal frequencies so as to block their transmission over the circuit W to terminals 26 but accept transmission from terminals 26 to the modulator circuit 19. The network 18 is arranged to provide frequency equalization which may replace that normally provided in the repeater. An equivalent form of the networks 17 and 18 is described with reference to Fig. 5 (not shown), this network having only one transformer 27 coupling the line to both input and output of modulator circuit 19.

A differential for use in an automotive drive axle, for example, has a filter through which lubricant is centrifuged unidirectionally, centrifuging of the lubricant being effected in response to the driving of the differential parts. In an embodiment a filter 67, Figs. 2 and 3, is urged by a spring 71 against a peripheral wall 51 of a drum member 34. The latter is attached by bolts 62 to a ring-gear 30 and is provided with circumferentially-spaced scoops 63 which, when the drum member 34 rotates, collects lubricant from a reservoir in the housing and delivers it to the inside of the drum member 34. The lubricant passes to the external surface of the peripheral wall 51, via the filter 67 and holes 52 which are circumferentially spaced in the peripheral wall 51. Lubricant which is already on the wall 51, having been collected direct from the reservoir, and the lubricant which is filtered, is removed from the wall 51 by means of a scraper and is directed to a bearing of the differential. Other bearings are lubricated by conventional lifting means, the lubricant being obtained direct from the reservoir. The spring 71 may be magnetized in order to remove ferrous metal particles from the lubricant prior to it being filtered.

The tube 1 is in two parts, 1a, 1b meeting at the valve unit 5. The part 1a has a suitable end allowing the gas sample to be collected, e.g. gas from small volumes of blood or from a patient's lungs, and in operation the gas through the tube 1 to the valve unit 7. This unit has a plunger 22 (Fig. 2) adapted to be moved vertically within a bore 20 by angular rotation of a plate 36 having a suitably shaped slot 35. The lower ends of the plunger 22 and bore 20 engage closely and the vacuum pump 8 is connected to the bore 20 through a duct 29. The tube 1 leads through the plunger 20 to a small chamber 27 closed by a porous disc 28, e.g. of sintered silicon carbide, leading to the ion source 3. By altering the position of the plunger 22 the rate of flow of gas through the tube 1 and the pressure in the chamber 27 may be adjusted thus controlling the escape of gas through the disc 28. The disc 28 may be replaced by a short capillary tube leading to the ion source 3 if desired. In the event of a blockage of the tube 1 by condensation or solid particles, the part 1b of the tube may be sealed off by closing a valve 9. Then by opening a screw-down valve 11 oxygen under pressure may be passed through the part 1a of the capillary tube to clean it. If desired, both parts 1a, 1b of the capillary tube may be cleaned. The tube 1 may be electrically heated to reduce condensation by passing an electric current through the tube and a copper braiding surrounding the tube and insulated from it by a layer of woven glass or nylon sleeving.

Title: Selective hydrogenation of esters of poly-unsaturated fatty acids
Inventor: SCHULZ RICHARD FRIEDRICH ADOLF
IPC: C11C3/12
Filed: 1963-11-19
Abstract: Esters of polyunsaturated fatty acids, particularly triglycerides, are selectively hydrogenated in the presence of a hydrogenation catalyst in such a way that the reduction of polyto mono-unsaturated groups is favoured at the expense of reduction to saturated groups, the hydrogenation being carried out in the additional presence of 0.01-4.5 weight per cent based on the ester, of a non-acidic organic compound containing at least one alcoholic hydroxyl group.  Typical additives are monohydric alcohols (e.g. n-octanol), polyhydric alcohols (e.g. ethylene glycol, sorbitol), hydroxy-ethers (e.g. butoxy-ethanol, furfuryl alcohol), amino-alcohols (e.g. triethanolamine), and partial fatty acid esters of polyhydric alcohols (e.g. polyethylene glycol monostearate). Numerous examples of such additives are given in addition to those specified above, and the additive may also be produced in situ during the reaction by hydrogenation of a reducible aldehyde, e.g. benzaldehyde.  Suitable hydrogenation catalysts are Raney nickel, or kieselguhr, and reduced nickel formate. Examples describe the selective hydrogenation of soyabean oil, cottonseed oil, groundnut oil, rapeseed oil, palm oil, and desulphurized whale oil.
