Title: Method and means for setting up printers' copy for photo-mechanical reproduction
IPC: G03F1/90
Filed: 1952-02-29
Abstract: 714,630. Signs. MARKOWITZ, M. Feb. 29, 1952, No. 5341/52. Class 3(2) [Also in Group XX] A method of preparing printers' copy for use in photo-mechanical printing comprises the steps of applying printing characters or other matter for printing to a sheet of severable material having a squared pattern printed thereon in a manner which can be eliminated photographically, severing from the sheet sections having one or more characters applied thereto, or portions of said matter for printing, and re-assembling the sections in desired relation on a base sheet printed with a squared pattern identical with that on the sheet bearing the printing characters or other matter, the pattern lines on the sections being registered with those on the base sheet, whereby a copy is obtained ready for photo-mechanical reproduction. As shown in Fig. 7, a base sheet B has printed thereon a squared grid of lines 11 of such intensity and colour (e.g. pale green) that though clearly visible they may readily be eliminated in photographic reproduction. Sets of characters are printed on a sheet similar to B, each character resting on one of the lines 11 as a base line and being intersected by at least two pairs of lines at right-angles. The printed sheet is cut into pieces 10 each bearing a character, and the pieces are fixed to sheet B to form words, the lines 11 on the pieces 10 being lined up with the lines on sheet B to give correct alignment and spacing of the characters. The complete sheet is photographed for photo-mechanical reproduction. If a diapositive is required, the characters may be white on a dark background, and the lines 11 may be dark in colour. For use in signs the characters may be stuck on sheet B, or printed on thin sheet steel, cut up, and placed on a magnetic lined plate. The lines are then illuminated by light of such a colour that they are not seen. In a modification, matter to be reproduced in several type styles is printed on squared paper, in the required styles, but without regard to arrangement. The matter is then cut up in blocks and arranged by sticking the blocks on another sheet of squared paper. The resulting sheet is photographed for reproduction.

Abstract: 415,067. Bending plates for boiler shells. EUMUCO AKT.-GES. FUR MASCHINENBAU, Schlebusch, Leverkusen, and SCHNEIDER, A., 11A, Arnulfstrasse, Oberkassel, D³sseldorf, both in Germany. Feb. 19, 1934, No. 5382. Convention date, Feb. 17, 1933. [Class 83 (iv).] In bending long tubes of small diameter for high pressure boilers, a strip is positioned on a die 19 beneath a beam 6 containing hydraulic pistons 8 and supporting a beam 18. An abutment 9 is adjusted bymechanical or hydraulic means to contact the member 18 and pressure is applied to the pistons to bend the strip between the dies 7, 19. The strip is supported on a table 1. Each descent of the die 7 depresses rods 11 which lift the roller table 1 to support the strip during bending. For lighter work some of the pistons 8 may be inoperative. The beam 6 is guided in side frames one of which is jointed to allow of the removal of the tube. The strip is formed to a half cylinder and is then turned round and the other half is bent. The seam slit may be closed by inserting a bar or bars 18 in the die 7, by using a die 9 of greater curvature than that of the pipe, or by applying pressure normal to the plane of the slit.

Title: Improved Method of and Apparatus for Bending Wire into Loops.
IPC: B21F35/04
Filed: 1918-03-27
Abstract: 124,576. Marks, E. C. R., (Aktiebolaget Lidkopinas Mekaniska Verkstad). March 27, 1918. Clutches, claw; clutches friction.-In a machine for bending wire into loops the cooling member 65 is rotated intermittingly by a spur-wheel 67 loosely mounted on a continuously driven shaft 17, and secured to a clutch member. The wheel 67 is reciprocated along the shaft by cam-operated arms 80 so as to throw the clutch member into and out of engagement with a co-operating member secured to the shaft. The clutch member 68 secured to the wheel 67 has radially-disposed pivoted arms 70, the inner ends of which are urged by springs 72 against a smooth face on the clutch member 75 carried by the shaft 17, giving a friction drive. As the wineel 67 and member 68 are moved towards the member 75, the outer ends of the arms 70 are caused to project from the member 68 and engage suitably formed radial teeth on the face of the member 75, giving a positive drive.

Title: Improvements in or relating to landing gear for aircraft
IPC: B64C25/60
Filed: 1946-02-21
Abstract: 606,163. Aircraft landing gear. BENDIX AVIATION CORPORATION. Feb. 21, 1946, No. 5416. Convention date, June 25, 1945. [Class 4] [Also in Group XXXII] In aircraft landing gear having a shock strut comprising two telescoping members, one 14 connected to the aircraft and having a bearing 50 at its lower end, the other 12 carrying a ground contacting element (not shown) and supporting a bearing 48 at its upper end, an annular chamber 66 being formed between the bearings 48, 50, into which fluid is forced to shorten the strut prior to retraction, an annular floating piston 52 is located in the annular chamber to act as a spacer for holding the bearings 48, 50 a predetermined distance apart in the fully-extended position of the strut and to act as a piston under the action of the pressure fluid to shorten the strut. The floating piston 52, Fig. 3, has inner and outer packing rings 74, 76. An inlet 80 to the lower part 67 of the space 66 below the piston 52 provides a connection with an hydraulic pressure system on the aircraft so that according to the setting of suitable control means (not shown) the space 67 may be either subjected to hydraulic pressure or connected to a reservoir of the system. The upper tubular member 14 carries a concentric hollow piston rod 28 the piston 30 of which has an orifice 32 which co-operates with a metering rod 18 carried by the member 12. An annular member 64 in the upper part of the space 66 allows relatively free flow into the space 66 but is pressed against the bearing-spacer member 48 by outward flow which has to pass through orifices 72 in the member 64. Oil and air are charged into the leg at 22. Holes 38, 40, 42, 44, 46 permit free communication between the interior and exterior of the pistonrod 28. In operation, on take off, the leg extends under gravity and air pressure in the space above the piston 30, to the position shown, the piston 52 and member 64 acting as combined spacing member between the bearing members 48, 50. Hydraulic pressure is then applied to the connection 80 and acts on the piston 52 to retract the lower tubular member 12 into the member 14 and during this operation air may be released to a suitable reservoir (not shown). The shock absorber is then sufficiently shortened to allow the landing gear to be retracted. After subsequent extension of the landing gear prior to landing the pressure is released from the inlet 80 and the leg extends once more to be ready to withstand the landing shock.

Filed: 1965-03-03
Abstract: 1,145,681. Rotary pumps and motors. G.A. FAIRBAIRN. June 3, 1966 [March 3, 1965; Aug.3, 1965], Nos. 5574/66 and 33047/65. Heading F1F. A rotary pump or motor, described as a liquid pump, comprises a casing 10, Fig. 2, having an annular chamber 11 in which rotates a plurality of equispaced piston elements, two, 13a, 13b shown, carried by a rotor 12 mounted on a shaft 18 driven, e. g., from the power take-off shaft of an agricultural tractor. A valve disc (or discs) 14 having a plurality of apertures equal in number to the number of piston elements is mounted on a shaft 23, Fig.4 disposed at right angles to the shaft 18 and driven at the same speed as that shaft through skew gears 21, 22 so that the piston elements pass in timed relation through the apertures. Water entering the casing 10 through an axial inlet passage (19), Fig. 3 (not shown) passes between spokes 12b of the rotor 12 and through an inlet port 15 into the annular chamber 11 and leaves the annular chamber through a port 16 on the other side of the disc 14. The periphery of the disc 14 rotates in an annular pocket 28 both larger in width and diameter than the disc so that water admitted to the pocket from the inlet side of the pump through an opening 28a acts on both sides of the disc to eliminate deformation of the disc and reduce friction between it and the casing. The port 16 is tangentially disposed with respect to the annular chamber 11 to provide smooth flow and the piston elements are disposed so that at least one is between the inlet port 15 and the port 16 to prevent back flow. When there is more than one valve disc, each disc includes an associated inlet port and outlet port disposed one on either side of the disc at its position of intersection with the annular chamber. The number of piston elements however is greater than the number of inlet ports and the number of outlet ports.

Patent GB-198077-A (GB)
Title: The manufacture of vat-dyestuffs of the anthraquinone series
Filed: 1922-02-27
Abstract: Vat dyestuffs, which are most probably oxazoles and thiazoles of the anthraquinone series are obtained by condensation of the azomethine compounds derived from anthrqquinone-2-aldehyde or a substitution product thereof, and an o-aminophenol, or an o-aminothiophenol or an equivalent thereof respectively; the condensation is effected by heating alone or with a solvent, and with or without a condensing agent such as sodium acetate, zinc chloride, or sulphuric acid.  A mixture of an anthraquinone-2-aldehyde with an o-aminophenol or an o-aminothiophenol may also be condensed directly to the dyestuff without isolation of the azomethine compound.  Equivalents of o-aminothiophenols are aromatic amines sulphurized in the ortho position such as o-diaminoaryldisulphides, o - aminoarylthiosulphonic acids and particularly the substances described in Specifications 17417/14 and 18292/14 derived from the action of disulphur dichloride on primary aromatic amines, and their products of transformation. The thiazoles may also be obtained by heating with sulphur either the azomethine compounds from anthraquinone-2-aldehydes and primary aromatic amines having one free ortho position to the amino group, or mixtures of anthraquinone-2-aldehydes with such primary aromatic amines.  The products dye vegetable fibres in fast shades from the hydrosulphite vat; those products which contain several thiazole or oxazole rings are particularly valuable.  In examples, the following products are described:-(1) oxazoles dyeing cotton and wool bluish-red shades from 1-aminoanthraquinone-2-aldehyde and 4-nitro-2-aminophenol or 1-amino-2-naphthol; (2) an azomethine vat dyestuff, from 1-aminoanthraquinone-2-aldehyde and 2-amino-1-naphthylmercaptan, which is converted into a bluish-red thiazole by boiling with potassium acetate in nitrobenzene; the same product is obtained by heating with sulphur the azomethine compound from 1-aminoanthraquinone-2-aldehyde and b -naphthylamine; (3) a claret-red dyestuff from 1-amino-anthraquinone-2-aldehyde and di-o-mercaptobenzidine or benzidine-dithiosulphoxide; (4) a dithiazole, dyeing cotton reddish-yellow shades, from anthraquinone-2-aldehyde and benzidine dithiosulphoxide, or by sulphurizing either the azomethine compound from the aldehyde and benzidine, or a mixture of the components; (5) a dithiazole dyeing cotton in violet shades by sulphurizing the azomethine compound from 1-aminoanthraquinone-2-aldehyde and p-phenylenediamine; (6) a brownish-violet thiazole by sulphurizing the azomethine compound from 1-aminoanthraquinone-2-aldehyde and 4-amino-41-oxydiphenylamine.
