Classes 7(2) and 7(3) In the cylinder head of a liquid-cooled internal-combustion engine having valve passages 15, 16, Fig. 1, in the head and a cooling arrangement in which the coolant is caused to flow transversely in the head in relation to the longitudinal cylinder axis and wherein channels, such as 25, formed between adjacent walls 19 and 20 of the valve passage and which communicate with each other closely above the base of the cylinder head conduct coolant, introduced from the cylinder jacket 5, Fig. 2, in a number of streams which correspond to the number of channels, the coolant passing into the head is caused to flow with increased velocity by means of deflectors 31, 33, Fig. 1, for example, the channels,. such as 23-25, Fig. 1, may also be formed between walls 11 of a pre-combustion chamber 9 and walls 19 and 20. The cylinder head 4, houses the inlet and exhaust valves 7 and 8, respectively, and the valve passages 15, 16 open into the top and far side walls, respectively, of the cylinder head, which passages are of nozzle form adjacent the valve seatings. The chamber 9 is formed by insertions 10, Fig. 2, which are either in direct contact with or separated by air spaces from the surrounding wall 11; fuel is injected into the chamber from a nozzle 13 axially aligned with the passage 12 by which the chamber is connected with cylinder 2. An incandescent sparking plug 14 projects into the chamber 9 on the side thereof remote from the valves. The three radial passages 23, 24 and 25, Fig. 1, converge'towards a central point 26 whilst the jacket 5 communicates through openings 28, 29, 30 with the cylinder head cooling jacket 6, the openings being situated at the outer ends of the radial passages. The discharge points of the openings 28-30 in the head are covered by the U-shaped deflectors 31-33, which direct the coolant in the form of jets along the passages to the point 26 from whence it flows upwardly; the deflector 31 serves two cylinders. Further openings 34, Fig. 2, may be provided between the cylinder and head cooling jackets. The invention is applicable to engines working on the Otto or Diesel cycle and particularly relates to Diesel engines with combustion chambers or air-cells located in the head, as well as to engines with three or more valves for each cylinder. The walls surrounding the bolts 3, Fig. 1, securing the head to the cylinder are made separate from the passage and chamber walls.

Abstract: 699,712. Photographic type-composing. MERGENTHALER LINOTYPE CO. Aug. 28, 1951 [Sept. 1, 1950], No.'20253/51. Classes 97 (i) and 98 (i). A photographic type-composing machine is provided with a source of light, an array of typographical characters, an optical system for projecting the light from the source upon the array of characters, masking means for the array adapted to permit the transmission of an image of any selected character in the array, a diffraction grating system for producing a multiplicity of secondary images from the transmitted image of the selected character, the arrangement being such that one of the secondary images is projected along the optical axis of the optical system, a masking screen upon which the secondary images are transmitted, the screen having an aperture for transmitting the secondary image falling along the optical axis, and a photographic light-sensitive recording surface for the image of the selected character transmitted through the screen aperture. As shown, a character-bearing plate 4 is illuminated by the mercury vapour lamp 1 and the filter 2, providing substantially monochromatic light, and the condenser 3. A single character is isolated by a pair of shutters 6, 7 having pivoted horizontal and vertical bars respectively, the appropriate bars being displaced by the operation of a keyboard. A collimating lens 8 renders the light coming from the single character practically parallel, and such light passes through a pair of crossed diffraction gratings 9 providing a multiplicity of images of the character, which images are focused by the lens 10 on to the masking plate 11 having a central aperture 12 permitting the passage of the light forming the central image only. This light, rendered substantially parallel by the collimating lens 13, is reflected by the prism 14 and focused by the lenses 15, 16 on the photographic recording film 5. The prism 14 and lenses 15, 16 are mounted in a movable carriage 17, which moves a set distance after the recording of each character. The point-size of the recorded image may be charged by vertical movement of the lens 16 and the film 5. The plate 4, which may be of glass or film, is removable to permit of its replacement by other plates being different characters, and may bear transparent characters on an opaque background or opaque characters on a transparent background. The diffraction gratings, which have alternate light-transmitting and lightabsorbing lines, may be replaced by gratings having alternate light-reflecting and lightabsorbing lines. The gratings may comprise ruled collodion coatings on a glass plate.

Abstract: 645,777. Magnetic tests and measurements. GENERAL ELECTRIC CO., Ltd., and MATTHEWS, A. Aug. 4, 1948, No. 20607. [Class 37] In apparatus for measuring the thickness of a non-magnetic coating on a magnetic base of the kind in which the test piece completes the magnetic circuit of a transformer, the magnetic circuit is first completed by an uncoated member of the same material and thickness as the base of the articles to be tested and its permeability is adjusted to bring the output of the transformer to a standard value by varying a direct current in the primary winding 2 or in a separate winding. The instrument 4 connected to the secondary winding may thus be calibrated in thickness since the above procedure compensates for errors due to variations in the thickness and material of the base in different articles tested.
