Title: Printing presses
IPC: B41F1/00
Filed: 1920-10-27
Abstract: 174,445. Waters, E. T. Oct. 27, 1920. Cylinder and like machines; platen machines. -In a printing-machine comprising a platen mounted to oscillate about a fixed axis and having a curved surface adapted to make rolling contact with an oscillating bed, the curved platen oscillates about a centre located between its curved surface and the centre of curvature thereof, and co-operates with a bed having a continuous to-and-fro movement towards the platen compounded with an oscillating movement in a direction tangential to the surface of the platen, so that the platen and bed are in rolling contact only during the latter part of the approach of the bed towards the platen and the early part of its motion therefrom, the amplitude of the oscillation of the platen and of the tangential motion of the bed being only a fraction of the length of sheet printed. The curved platen 28 is carried on a rocker 23 mounted on a rocker-shaft 22, which is osciillated by means of crank arms 25 having rollers 26 engaging face-cams 27 on the driving-wheels 20 on the main-shaft 21. The bed 50 is rocked towards and awav from the platen by means of the crank-pins 61 and sidearms 60 connected to the reduced eccentric ends of the back-shaft 59 extending through the rearward portion of the bed. The legs 49 of the bed are connected by a rising and falling fulcrumshaft 48 carried by arms 47 rigid with a shaft 46, to which is secured an arm 52 having a roller 57 at its upper end running in contact with a cam 24 on the shaft 21. The weight of the bed is counterbalanced by a spring 56 acting through a rod 53 connected to an arm 51 keyed to the shaft 46, and buffer-cylinder 88 is provided to counteract the momentum of the bed on its downward movement. For throwing off the impression, the backshaft 59 is provided with a crank 75 connected by a link 76 to one arm of a bell-crank 77, the other arm of which is slotted to receive a roller 79 on a quadrant 80 pivoted on a shaft 81 adapted to be rocked by an arm 82 connected by a link 83 to the lower end of the throw-off lever 84. The platen 28 is connected to its rocker 23 by means of four yielding adjusting screws of the construction shown in Fig. 10. Each screw has a square part 29 passing through the rocker and a collar 32 engaged by a spring 31, the compression of which is adjusted to the printing pressure required by the nut 30. The threaded part 33 engages a sleeve 35 which has an external thread of different pitch and screws into a threaded socket in the platen, so that by turning the sleeve 35 the platen is raised or lowered relatively to the rocker. By this means excessive pressure between the bearers 70 on the bed and the platen-bearer 37 is prevented by the yielding of the platen in case the normal printing pressure should be exceeded.

Title: Improvements in or relating to direction-finding systems employing aerial arrays
Inventor: HODGART MATTHEW STEPHEN
IPC: G01S3/64
Filed: 1969-06-16
Abstract: 1,270,704. Radio direction finding. GENERAL ELECTRIC CO. Ltd. 16 Sept., 1970 [16 June, 1969], No. 30459/69. Heading H4D. A direction finding system, Fig. 4, comprises an array of differently directed aerials 0-7 (e.g. a circular array, Fig. 1) having their outputs amplitude modulated by respective signals having the same frequency but with staggered phases (thick lines, Fig. 2) corresponding to the direction of the aerial, to give carrier (r.f.) frequency components and sidebands, which are then subjected to a plurality of further stages of amplitude modulation, each modulation stage comprises two half stages (A and B) operating with the same modulating frequency (f2, f3, f4), but in phase quadrature, one at least of the half stages giving suppressed carrier modulation and the signals due to any pair of aerials being subjected to quadrature modulation in at least one of the further modulation stages, the outputs of the modulation stages being combined (40) and fed to a square low detector 91 to give a component at the frequency f1 of the first amplified modulation the phase of which, relative to that of the first modulating signal, is representative of the received signal direction. In the system of Fig. 1, which is an intermediate stage in the development of the invention, the aerials 0-7 in the circular array receive and produce, for an incoming signal direction as shown by the arrow, r.f. signals having respective relative intensities shown by rightward position of the bar at the left side of Fig. 2. Each output is amplitude modulated by a signal at f1 and staggered in phase by #/4, round the array to give the respective shown outputs. The modulating means 10-17 each comprises a p.i.n diode across a waveguide junction. Each modulated output is amplified in a travelling wave tube 20-27, detected by a square law diode 30-37 and the component at f1 selected in a filter 40-47. The f1 components are combined at 48 and the resultant phase compared with the modulating signal at 49. In the embodiment of the invention, Fig. 3, the phase staggered modulation at f1 is carried out in three port waveguide switching means 51-54, the two input ports each having a modulating p.i.n. diode thereacross and each means also serving to combine the modulated signals from diametrically opposite aerials-e.g. 3-7, 6-2. The modulated and combined signal pairs are fed to a 1st suppressed carrier modulation stage comprising two quadrature halves, each comprising a pair of directional couplers 69/70, 67/68 and a pair of modulating diodes 66/65. The outputs of the 1st stage are combined in couplers 77, 78 to give two signals respectively made up of signals from aerials 0, 2, 4, 6 and 1, 3, 5, 7. These signals are subjected to further suppressed carrier modulation in a second modulation stage 63/64 also comprising quadrature halves and combined in coupler 83. Only one expensive travelling wave tube amplifier is thus needed.

Title: Sulphonates for use as leather fat-liquoring agents
IPC: C14C9/02
Filed: 1963-08-01
Abstract: Unsaturated fatty acid esters are peroxidized by treatment with an oxygen-containing gas, then deperoxidized by heating, before being sulphonated with SO3.  Suitable esters are natural and synthetic unsaturated esters containing no hydroxy groups e.g. sperm, olive, maize, neat'sfoot, mustard, rice, cottonseed and teaseed oils, or triolein or oleyl oleate. The peroxidation is effected at 65-100 DEG C., with or without a catalyst, preferably with air at 80-100 DEG  C. without catalyst, until the peroxide value is 200-700. The product is deperoxidized at 110-160 DEG  C., preferably 150 DEG  C., until the peroxide value is 0.  The sulphonation may be effected with 5-15% of SO3 (based on deperoxidized ester) preferably in the form of a 2-10% mixture with air or an inert gas.  The reaction product may be bleached with H2O2 at 50-70 DEG  C. before being neutralized and distilled to remove water.  Examples describe the treatment of sperm oil, triolein and of teaseed oil in this way and the use of the products in fat-liquoring leathers (see Division C6).ALSO:Leather may be fat-liquored by means of solutions containing compounds obtained by sulphonating with SO3 unsaturated fatty acid esters which have previously been treated with an oxygen-containing gas, and then deperoxidized by heating (see Division C2).  In examples chrome uppers and glove leathers are treated with 250% by weight based on leather of a liquor containing 5-6% based on the leather of sulphonates so prepared from sperm oil, triolein or teaseed oil, or 5-6% of a mixture containing 70% of such a sperm oil sulphonate and 30% of sperm oil, or 4-6% of a mixture of 70% teaseed oil sulphonate, 10% teaseed oil, 15% mineral oil and 5% of a fatty alcohol-ethylene oxide adduct.  Other suitable starting materials tested are olive, neat's foot, maize, mustard, rice, and cottonseed oils and oleyl oleate.
