Patent GB-340777-A (GB)
Title: Improvement in and relating to reversible rotary blowers or pumps
IPC: F04C28/04
Filed: 1930-01-01
Abstract: 340,777. Rotary pumps. KJAER, V. A., 16, Hoyensgade, Copenhagen. Jan. 1, 1930, No. 32. [Class 110 (ii).] A gear-wheel blower for supplying compressed air to an internal-combustion engine is driven by chains off the engine shaft and delivers air in one direction only regardless of the direction of motion of the blower. Two blowers 2, 3 are fixed to the frame of an internal-combustion engine 1 and deliver air through ducts 11 to two engine cylinders. Each flap valve 13 as drawn allows air which is sucked in through a strainer 9 to pass through a branch 22 to an inlet 25 of the blower 6. Delivery of the air is by way of a pipe 23 to the other side of the flap valve 13 and so to the engine duct 11. On reversing the engine, and thus the direction of motion of the blower, the flap valves are reversed by a hand-lever 21 and interconnecting link gear 20-14-15 so that the incoming air passes the reverse way through the blower out underneath the flap valve, thence to the duct 11. In a modification the blower casing is contained within an outer casing which is divided into two compartments. Pairs of valves connected by links open one of these compartments to the suction side of the blower and the other to the delivery pipe, one pair of valves being open and one pair closed depending on which way the blower turns. The reversing lever may be mechanically controlled.

Abstract: 1,127,374. Dyeing synthetic materials. FARBENFABRIKEN BAYER A.G. 2 Jan.. 1967 [19 Jan., l966], No. 49/67. Heading D1B. Synthetic textile materials made of polyesters, cellulose acetate. or polyamides are dyed by treating in a first stage with a substantially water-insoluble enol or phenol complex compound of copper, nickel, zinc or cobalt and then in a second stage with a pyrolenine followed by a thermal treatment to produce a porphyrazine on the fibre. In particular the pyrrolenine may be of formula in which R, and R, are substituents which may be linked to form a ring e.g. C 1 -C 6  alkyl radicals, or R 1  and R 2  may be joined to form an aromatic ring containing hetero atoms e.g. sulphur and nitrogen, R 3  is an amino group or an alkoxy group of 1-3 carbon atoms, R 4  and R 5  are methoxy or ethoxy groups or together form an imino group or a dionolane cycle. Benzopyrrolenines may also be used which contain in the benzene nucleous one or two alkoxy groups which may contain further substituents e.g. hydroxyl groups. The pyrrolenines may be used in admixture. Mixtures of the above mentioned synthetic materials with cotton are also dyed, a water-soluble organic or inorganic Cu. Ni Zn or Co compound being used for the cotton components. The metal complexes may be applied in neutral to weakly acid suspension at 90-130‹C. The thermal heat treatment may take the form of a thermorol process at 140-215‹C to produce the porphyrazine in situ. Acid or alkaline baths containing a reducing agent may be used as aftertreatment. In Example 4 polyamide material is printed with a reserve paste containing ZnO, crystal gum and diethylene triamine the fabric then being dyed as above.

Title: Process and apparatus for applying ink to the printing plates of high speed intaglio printing machines
IPC: B41F9/06
Filed: 1933-01-02
Abstract: 396,286. Printing-machines. NATIONAL BANK OF HUNGARY, 8, Szabadsagter, and HEINRICH, F. VON, 13, Marko Utca, both in Budapest. Jan. 2, 1933, No. 54. Convention date, Feb. 25, 1932. [Class 100 (ii).] Inking-apparatus.-In a high-speed intaglio printing-press, the ink is applied to the plate in a layer which gradually decreases in thickness from front to rear edge in proportion to the degree of saturation of the wiping material, so that after wiping the plate will be evenly inked and less ink will be wasted. An intermediate roller 1, Fig. 3, between, and driving frictionally, a duct roller and a plate-inking roller, not shown, is driven from a shaft 14 through planet gearing 15, 16, 17. The two planet wheels 16 are borne on an arm 7 which is oscillated by a cam and roller 11, 12. The planet gears produce a rotation in the roller shaft in an opposite direction to that of the driving-shaft 14, so that the acceleration of the planet wheels 16 round their own axes and round that of the shaft 14 produce an additive acceleration on the roller shaft. As the planet wheels are accelerated the roller 1 is accelerated, and vice versa. Retardation takes place while the plate is passing under the inking-roller and results in a gradual diminution of the thickness of the ink layer, and the rollers are then accelerated again in time for the inking of the next plate. In the modified form illustrated in Fig. 5, a casing 13 is oscillated about the axis 14 by the cam 11, and carries gear wheels 16a .. 16d. The gear-wheel 15 on the axis 14 drives the gear-wheel 16a, and the gearwheel 16b, which is fast to the shaft of the gearwheel 16a, drives the gear-wheel 16c. The gear-wheel 16d fast to the shaft of the gearwheel 16c drives a gear-wheel 17 which is fast to the shaft of the roller 1. The oscillation of the casing 13 produces the retardation and acceleration of the roller 1. The amount of variation in thickness of the ink-layer can be varied by altering the length of the arm 7. The invention may be applied to a multicolour machine in which several duct-rollers co-operate with one collecting roller and one inking-roller.

Title: Improved process and installation for physical and/or chemical treatment of yarns, warps and textile fabrics or similar goods
Inventor: KABELITZ HANS
IPC: D06C7/00
Filed: 1951-01-03
Abstract: In a process in which a stream of gas flows in the same direction as or the opposite direction <PICT:0718415/IV(c)/1> from a travelling material, the flow velocity is increased in the processing zone so that the Reynolds number exceeds the critical value.  The duct 2, through which the material is passed is arranged to increase in cross-section so that the gas or vapour slows as it passes along the duct.  It is then passed through a fan 3 and over heaters 8 to a chamber 10, the degree of heating being controlled by flaps 7, 7a. By operation of the flap 11, the gas or vapour may be diverted along duct 12 and through nozzles 13 to cause turbulence in the main duct 2.  Increased turbulence may be induced by the use of steel wires 14 and exhausting devices 15. The gas or vapour may leave through duct 18 and fresh gas or vapour drawn in through fan entry 16.  The chamber 1 is filled with leakage gases from the apparatus which together with thermal insulation in the walls reduces heat losses to the atmosphere. A series of treatment apparatus may be used, any one of which may be withdrawn from the process.  In a modification, (Fig. 2 not shown) the walls of the processing zone may be parallel.
