Title: Improvements in machines for off-set printing of articles having curved or irregular surfaces
IPC: B41F17/00
Filed: 1953-05-12
Abstract: 748,412. Printing with flexible surfaces. HARRISON, W. May 11, 1954 [May 12, 1953], No. 13163/53. Class 100 (2). A machine for printing articles having curved or irregular shaped surfaces comprises a suitably shaped elastic pad 5 attached to a vertically movable support 4, means for moving a design plate cylinder or band from which the print is to be taken, horizontally into a position directly under the pad and a vertically movable holder 6 for supporting for the article to be printed. The support 4 is guided on parallel rods 2 which also serve to guide the holder 6 during its vertical movement. The support 4 and holder 6 are displaced vertically by cylinders 8, 9 actuated by air pressure. The design plates 17 are supported on sliders 13 adapted to run on horizontal rails 7. For multi-colour printing a series of such sliders, each having a design plate, may be mounted in a rack which is displaced vertically or horizontally between printing operations to position each slider in turn in alignment with rails 7. A T-headed control rod may engage a shaped slot in each slider in the aligned position for displacing it to the position where the design plate is vertically under the pad. The pad is lowered to take an ink impression of the design plate which is then moved out of the transfer position. The pad is then lowered again into engagement with the article, and deforms to fit the surface to be printed. The pad is then cleaned by contact with an absorbent sheet if necessary and the process repeated with the next colour. The printing surface of the design plates may be intaglio, lithographic or a relief printing surface. In all cases they may be inked with a flexible roller. In the case of an intaglio plate a doctor blade is arranged to wipe over the printing surface to remove excess ink and to confine the ink to the engraved parts. Alternatively the ink may be applied by another doctor blade. The design may be engraved or etched on the surface of a cylinder or on a flexible sheet or band which may be fixed to the surface of a cylinder or used in continuous form passing over cylinders at each end and lying over the surface of the slide plate. The cylinder or band is moved to ink the design and co-operates with a doctor blade to remove excess ink. The slider conveying the cylinder or band is moved to bring the inked design under the pad as before. The elastic pad may be solid and of natural or synthetic rubber, or gelatine jelly. It may alternatively be hollow and shaped by fluid pressure, the walls of the pad being strengthened or controlled in shape by canvas or the like. Specification 23009/03, [Class 100], is referred to.

Title: Improvements in the manufacture and production of urethane derivatives
IPC: C07C271/16
Filed: 1931-05-06
Abstract: Urethanes are made by condensing a chlorcarbonic ester of the general formula Cl,COOR, in which OR is the residue of a mono- or polyhydric aliphatic or cycloaliphatic alcohol containing at least 6 carbon atoms, with a primary or secondary hydroxyalkylamine.  The chlorcarbonic esters of lauryl and octodecyl alcohols, cyclohexanol and octodecandiol are specified. Suitable amines are N-ethanolaniline, N-ethanol-p-toluidine, mono- or diethanol- or propanolamines, mono- or dibutanolamines, cyclohexylmonoethanolamine, b -ethylhexylmonoethanolamine and a -amino-b -#c-dihydroxypropane. The condensation may be effected in presence of caustic alkali or other basic substance or with excess of amine with or without solvents.  In examples (1) the chlorcarbonic ester of octodecylalcohol is condensed with monobutanol amine in presence of aqueous caustic soda, (2) the chlorcarbonic ester of cetyl alcohol is condensed with N-n-butylethanolamine in water containing calcium hydroxide, (3) the chlorcarbonic ester of octodecandiol is condensed with aqueous propanolamine.  Chlorcarbonic esters above referred to are made by treating the corresponding alcohol with phosgene, with or without a solvent, e.g. carbon tetrachloride. Cyclohexylmonoethanolamine is made by condensing cyclohexylamine (2 mols.) with ethyleneoxide (1 mol.).  b -Ethylhexylmonoethanolamine is made from equimolecular proportions of ethyleneoxide and b -ethylhexylamine.  b -Ethylhexylamine is made by catalytically reducing, by means of hydrogen in the presence of ammonia, the unsaturated aldehyde produced by splitting off water from butyraldol. Ether-alcohols are obtained by treating the above urethanes with alkylene oxides.

Title: A new or improved control for hydraulic servo mechanism
Inventor: SADLER FRANCIS ANTONY DAWSON
IPC: B60T13/16
Filed: 1955-05-11
Abstract: 795,874. Hydraulic control for vehicle clutches or brakes. GIRLING, Ltd. Aug. 13, 1956 [May 11, 1955], No. 13610/55. Class 69 (2). [Also in Groups XXIV and XXXIV] In an hydraulic system in which a pump supplies liquid to one or more slave cylinders, which may operate a vehicle clutch or brake, the supply of liquid is controlled manually through a spring and a valve, the valve being sealed against leakage by a diaphragm. In one form, liquid from a pump 24 passes via a pipe 23, the manually operated valve 12, a chamber 16, a pipe 30, and another pipe 32, to a tank 33. The valve is in the form of a sleeve having a recess 21 and a shoulder 18 which engages an abutment 19. When a pedal 44 is depressed, a spring 27 is loaded and gradually closes the gap between the faces 18, 19 and the pressure in the pipe 23 increases until it is sufficient to open a spring- loaded valve 35, thereby connecting the pump delivery to a pipe 39 leading to a slave cylinder. The depression of the pedal causes a plunger 25 to force liquid which is inside the valve 12 through a port 42, passages 41, 32, and a chamber 31, to the tank. If the pump fails and the pedal is depressed, the valve 35 remains in the position shown in Fig. 1 and the liquid inside the valve 12 is forced through the port 42, passages 41, 39, and an annular groove 38, and operates the slave cylinder. A diaphragm 17 seals the piston and a second diaphragm 14 may be provided and is subjected to the pressure of the liquid in the pipe 30 via a pipe 30<SP>1</SP>. The second diaphragm balances the force on the diaphragm 17. In another embodiment, the diaphragm 14 is replaced by a spring located on the outside of the diaphragm 17. In a further embodiment (Fig. 10), for operating a clutch, the valve is in the form of a plunger 98 operating in a bore 90. The pump delivers to an inlet 93 and liquid returns to the tank from an outlet 94. The slave cylinder is connected between the pump and the port 93. A spring 107 balances the pressure on the diaphragm 96. An axial bore 109 and radial ports 110 connect a chamber 95 with the outlet 94. When the pedal is released, liquid passes through the inlet 93, the chamber 95, ports 110, and the bore 109 to the outlet 94. When the pedal is depressed, a head 100 on the valve engages the end of the bore 90 and the pressure in the pipe between the pump and the valve increases and operates the slave cylinder connected to the clutch.
