Abstract: 1528459 Relief printing plates ASAHI KASEI KOGYO KK 26 Sept 1975 [26 Sept 1974 31 March 1975 28 April 1975 22 May 1975 5 Sept 1975] 39509/75 Heading B6C A printing plate comprising a support 3 with relief image areas 2 is provided with small projections 1 in non-image areas which prevent staining of a substrate with ink in these background areas. The image relief is at least 0À05 mm. higher than the small projections and typically has a height of 0À06 to 0À5 mm. The small projections cover not more than 30% of the non-image areas of the support 3 and have individual areas and frequencies such that even if they do carry ink the result on a subtrate will not be noticeable, i.e. areas of not more than 0À04 sq. mm. and distributions of 20 to 4000 per sq. cm. The printing plate is generally produced by a method involving photocurable resin. In one embodiment, the support is transparent to actinic radiation and coated with photocurable resin; a negative image-bearing transparency contacts the resin layer and a dot-image-bearing transparency is located next to the support; exposure may be in any order or simultaneously through both transparencies, followed by washing out of uncured resin. The photosensitive resin may be exposed overall to a limited extent before exposure through the transparencies in order to activate the resin. The dot-image-bearing transparency may be incorporated in the support. In another embodiment, the small projections are pre-formed on the support prior to coating with photosensitive resin and imagewise exposure, the pre-forming being by embossing, incorporating small granules on a separate photographic process using a half-tone screen. Duplicate plates can be produced from the plates according to the invention by stereotype or electrotype procedures.

Title: Flight attitude control system for multiple-engined vertical take-off and landing aircraft
Inventor: PFAFF FRITZ
IPC: B64C29/00
Filed: 1968-08-22
Abstract: 1,241,986. Flight attitude central system. VEREINIGTE FLUGTECHNISCHE WERKE-FOKKER G.m.b.H. 22 Aug., 1968 No. 40264/68. Heading B7G. A flight attitude control system for a vertical take-off and landing aircraft with engines off-set from the centre of gravity, and flight attitude control nozzles which can be actuated by a flight attitude regulator or by the control column, comprises first flight attitude control nozzles 4, 5 from which a steady stream of compressed air may be blown out continuously and which are controlled differentially, second flight attitude control nozzles from which compressed air may be blown out only intermittently and a thrust modulation device 23 for varying differentially the thrust of the engines. The system is such that to compensate for small irregularities in attitude the first nozzles may immediately blow out compressed air from those parts of the engine from which air may be bled continuously but that for major faults of long duration, such as an engine cutting out, compressed air may be blown out from those parts of the engines from which air may be bled only intermittently and then thrust modulations may be employed. An input from the control column or the attitude gyros to the flight attitude regulator 1 is transmitted by a servomotor 2 to a link valve with three control slots 3, 6, 8. The first slot 3 acts immediately to control the first downward blast nozzles 4, 5 by a valve 21, and then slot 6 coupled to slot 3 and with a lost motion may open either the upward or downward nozzle 7 for " intermittent " air, but, due to the lost motion, only in the case of major signals from the flight attitude regulator 1. The thrust modulation device 23 owing to its lost motion and a delay element 9, only becomes effective in the case of major signals of long duration. In an alternative arrangement, Fig. 2b (not shown), the link (6<SP>1</SP>) controlling the nozzle 7, is coupled to the thrust modulation linkage 23 after the delay element 9 so that the intermittent compressed air and the thrust modulation intervene jointly only after major faults of long duration. The system may be also electrical, Fig. 4 (not shown), or hydraulic, Fig. 5 (not shown). In the latter the delay element is an hydraulic servo element (24) which has a servo valve with the characteristic that it delivers very small flow quantities for small signals and very large quantities for large signals, so that small signals are executed very slowly and large signals very rapidly.

Abstract: 1,060,858. Evaporators, film-type. W. BUCHI and P. JANOSFIA. Oct. 14, 1963 [Oct. 14, 1962], No. 40391/63. Heading B1B. Liquid is evaporated in the form of a film on the inner surface of vertical cylinders 19, which is surrounded by heating chamber 25, efficient heat-transfer to the liquid film being promoted by setting up interference waves in the film by means of a rotating band spiral 4 which oscillates in a vertical direction. The band is attached at its upper end to bell 3, and may be attached at its lower end to cylinder 5. The diameter of the spiral can be altered by twisting the ends. At its largest diameter the spiral lies on cylinder 19, at its smallest on cylinder 5. The spiral may, alternatively, be used hanging freely downwards over cylinder 5. The bell, cylinder 5 and spiral are rotated at about 500 to 700 r.p.m. by shaft 1. The spiral may be of such elasticity that it oscillates naturally; alternatively the spiral can be a stiff body which is made to oscillate by electro-magnetic or mechanical means. The liquid-to-be-evaporated is introduced into the evoporator through connection 23. The liquid flows through gap 27, between ring 26 and the wall of the housing, onto the inner surface of the heated cylinder 19, where it is distributed as a film. As the liquid evaporates, the most volatile components pass as vapour through holes in bell 3 into space 29, and then leave the evaporator through connection 24. Vapours of the components of intermediate volatility pass through perforations 6 in cylinder 5, and are condensed on cooled tubes 7 and 8. The condensate flows out of the apparatus through connection 14. The unevaporated residue of the feed liquid leaves the evoporator through connection 18. The apparatus may be used for the short-path distillation of liquids of high molecular weight.
