Abstract: 431,345. Oil engines. RICARDO, H. R., 21, Suffolk Street, Pall Mall, London. Jan. 4, 1934, Nos. 338 and 33685. [Class 7 (iii)] In a compression-ignition engine of the type in which, during the compression stroke, substantially the whole of the air charge is forced through a tangentially-arranged passage G in a heat-insulated plug E into a combustion chamber D which is symmetrical about a plane containing the axis of the passageway and an injector H and which is formed as a solid of revolution about an axis at right angles to this plane, the fuel jet K is directed towards a point on the wall, whose angular spacing from the injector, in the direction in which the air circulates lies between 120‹ and 165‹, and preferably between 120‹ and 150‹. The combustion chamber may be spherical, spheroidal, cylindrical, or barrel-shaped, or may be formed by a double concave or double convex lens, or by two truncated cones whose smaller ends are in open communication. The axis of the passageway may intersect that of the cylinder bore or pass to one side thereof, whilst the plane of symmetry may be inclined to the cylinder axis. The axis of the fuel jet may coincide with the axis of the injector, which may be arranged horizontally, Fig. 4, or vertically so that its axis is tangential to a circle whose radius is between a quarter and a half of the radius of the chamber ; or, as shown, the nozzle may deliver fuel obliquely. In Fig. 4, the jet impinges upon a liner L which is spaced from the walls of the chamber. Specifications 371,025 and 384,340 are referred to.

Patent GB-587105-A (GB)
Title: Manufacture of dithiocarbamic acid esters
Filed: 1945-01-04
Abstract: Dithiocarbamic acid esters are prepared by reacting a disubstituted dithiocarbamic acid or a salt thereof with a tertiary mono- or di(halogenalkyl)-amine, and, if desired, converting the product into a quaternary salt by treating it with a reactive ester of an alcohol. Instead of using the disubstituted dithiocarbamic acid or salt, compounds may be used which will react to form one of these during the process, such as a secondary amine and carbon disulphide.  The reaction may be effected in an inert solvent.  The quaternary salt may be prepared by treating with an alkyl halide, an aryl-sulphonic acid ester, a dialkyl sulphate or an aryl-alkyl halide.  In the examples: (1) sodium dimethyl (and diethyl) dithiocarbamate is refluxed with b -chloroethyl-dimethylamine hydrochloride to give dimethyl (or diethyl) dithiocarbamic acid b -dimethyl aminoethyl ester.  The corresponding quaternary salts are obtained by treating the products with methyl iodide, methyl chloride, dimethyl sulphate or dodecyl bromide respectively or by starting with the corresponding quaternary chlorethylamines.  (2) Diethylamine in ethyl acetate is added to carbon disulphide and b -chlorethyldiethylamine and the mixture refluxed.  (3) Sodium dimethyl-dithiocarbamate and di-(b -chlorethyl)-methylamine hydrochloride are refluxed in ethyl acetate. The product is converted into the quaternary salts by treatment with methyl iodide and dimethyl sulphate respectively.  The products of the invention possess therapeutic properties, for example in the treatment of skin diseases. Additional starting materials mentioned are piperidino-and morpholino-dithiocarboxylic acids and g -chloro propyl-diethylamine, g -chloropropyl-din-butylamine, N-(b -chlorethyl)-piperidine, N -(g -bromopropyl)-piperidine, N-(g -chloropentyl)-piperidine, N-(b -chlorethyl)-morpholine or N-(b -bromethyl)-piperazine.  The Specification as open to inspection under Sect. 91 states that a quaternary mono- or di-(halogen alkyl) amine may also be used as starting material.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the operation of machines having a reciprocating main motion
IPC: F04C14/22
Filed: 1935-01-05
Abstract: 432,005. Hydraulic transmission of power. WALDRICH, A., 68, Hahnweg, Coburg, Germany. Jan. 5, 1935, No. 454. [Class 69 (ii)] In a machine having a part reciprocated by hydraulic means comprising a primary pump reversed by a hydraulic servomotor, a main valve is actuated manually or from the machine part for securing the reversal of the servomotor and pump, and another valve operated from the servomotor coacts with the main valve when the latter is put into its mid-position to stop the drive. The primary pump 2, Fig. 1, may be moved to reverse and vary its output by means of a nut 6 engaging a screwed spindle 5, the nut being fixed to the spindle of a servomotor having a vane 7 and the spindle being provided with an arm 9 coacting with adjustable motion-limiting stops, and with a sprocket wheel 10. Pressure liquid for operating the servomotor is derived from an auxiliary gear-wheel pump 30, Fig. 3, and the circuit includes a main valve 17 and a valve 20, the latter being connected to the servomotor spindle by a sprocket chain. One end of the valve 17 is formed as shown in Fig. 4, to control connection between pipes 15, 16 and a suction pipe 33, while the other controls connection between the pressure pipe 29 and the valve 20. A pressure-relief valve 31 is provided, and the lever 25 for operating the valve 17 may be actuated manually or by movable dogs 26, 27. When the valves 17, 20 occupy the positions shown in Fig. 3, the vane 7 and pump 2 are in mid-positions and the hydraulic drive is interrupted, since the pump 2 is not delivering. By moving the lever 25 into the position T or U, the valve 17 is turned to establish connections for moving the vane 7 and pump 2 into an end position. If desired, the servomotor may consist of a cylinder with a piston or piston rod having a rack to turn the nut 6.

Title: Process for compensating for thickness variations in photographic image layers
IPC: G03C7/18
Filed: 1943-01-11
Abstract: 564,553. - Photographic printing process; colour photography. KODAK, Ltd. (Eastman Kodak Co., and Evans, R. M.). Jan. 11, 1943, No. 519. Drawings to Specification. [Class 98 (ii)] A method of compensating for the extrinsic density variations of a photograph due to variations in the thickness of the image 'layer, comprises combining in register therewith a mask of opposite sign and of lower contrast measured by light by which it is to be viewed or printed, the mask being one made by printing from the photograph using light which is absorbed to a higher degree by the binder of the image layer than is the light by which the combination is to be viewed or printed and by development to a gamma of less than one. If the binder is colourless, it can be dyed with a yellow dye and printed by blue light on to a blue sensitive material. In viewing or printing the combination of mask and original, either yellow light may be used or the yellow dye may be first bleached and printing or viewing done with blue light. The mask may be made on a thinly coated emulsion layer and some densities in the mask made to fall on the shoulder of the H and D curve. The combination of mask and original may be viewed with light strongly absorbed by the image to give an increase in contrast. Colour correction may be simultaneously effected by uniformly dyeing the original with a dye (e.g. Ink Blue) accentuating density variations due to thickness, printing a mask from the original with light chosen to give the desired colour correction, processing the mask to a gamma which is approximately the reciprocal of the factor by which the density variations were accentuated, bleaching the dyed original to remove only the uniform dye (but not the image dyes), and printing a colour duplicate from the registered combination. Alternatively, colour component negatives to be used in imbibition or other colour processes may be made. Numerical details of the method are given. Specification 551,614 is referred to.

[Also in Group XXIII] Panels, particularly for concrete shuttering, are formed of solid wood boards butt-jointed and glued with a glue resistant to concrete water, such as phenol-resorcinol-formaldehyde, phenol-melamine, urea formaldehyde concentrated with melamine, ethoxyline resin and polyurethane resin. The butting surfaces of the boards may be plane or may have mating projections and recesses; the projections and recesses should not have sharp or re-entrant angles but should have the form of a smooth curve such as a sine curve and the recesses may be slightly larger than the projections so that a glue gap is formed from which glue spreads over the whole butting surfaces as the boards are pressed together. The cross-grain ends of the boards are sprayed with a steam-proof agent and the boards are preferably arranged so that their heat-side surfaces alternately face opposite ways. After burning out resinous patches and making them good and grinding or scraping out rough fibrous patches, one surface of the panel and the edges may be covered with sheet of plastic by gluing, melting or pressing or with one or more layers of varnish. To render the panels proof against insects and moulds pentachloro-phenol or its sodium salt may be added to the glue, the varnish or the wood itself.

Title: Method for manufacturing an absorbent product
Inventor: BRISEBOIS HENRI
IPC: B31D1/04
Filed: 1997-04-10
Abstract: A method for manufacturing a layer of a laminated, disposable absorbent product (10), such as a fluid-permeable cover layer (12), an absorbent core layer (14) and a fluid-impervious backing layer (16) thereof, with a conparatively small amount of waste matter. The method conprises the steps of longitudinally cutting a continuous web (32) of starting material according to a cyclic pattern (34) constructed with line segments corresponding to the edge contour of the disposable absorbent product. The cutting operation divides the continuous web in two strips (36,38), each strip having a patterned longitudinal edge whose outline corresponds to the cyclic pattern. The strips are crossed and joined to one another in a parallel and in a phase relationship to form a compound web having longitudinal edges producing repeatedly the edge contour of the disposable absorbent product. The invention extends to integrating this method into an operation for manufacturing disposable absorbent products, and to an apparatus for carrying out the methods according to the invention and the resulting products. <IMAGE>   <IMAGE>
