Abstract: 1,237,731. Selective printing. INTERNATIONAL STANDARD ELECTRIC CORP. 11 Sept., 1968 [19 Sept., 1967], No. 43143/68. Addition to 1,140,286. Heading B6F. A selective printer as described in the parent Specification 1,140,286 and including a rotary type basket 3 mounted fast on a shaft 11a and provided with an array of radial type bars 14 is modified in that the axis or rotation 10a of the type basket 3 is disposed behind the printing position 2 by a distance x which is determined primarily by the radial length of the type bars 14. In operation a type bar 14 is selected for impression at a selecting station 24 and raised upwardly by a cam 20, Fig. 2, integral with a guide ring 17, which maintains the type bars 14 in the radial plane of the type basket 3 by engaging the distal projections 14a on the type bars. Continued rotation of the type basket in the anti-clockwise direction forces the selected type bar against an advance cam 17a such that the type bar is impelled into contact with a printing cam 21a which in turn impells the type bar against the platen 1. Following impact the type bar rebounds from the platen whereupon the type bar is intercepted by a resetting cam 21b, which restores the type bar downwardly such that the type bar rides along a follow-up cam 17b and subsequently enters a cut-out 17d adjacent which is disposed a restoring flap 17c. Type-carriages.-The type basket 3 which is continuously rotated by a gear 8 mounted slidably on a shaft 7 and meshing with a gear 9 fast with the shaft 11a is provided with rollers 5 for movement on guide rails 6 which extend parallel to the platen 1.

Filed: 1968-09-13
Abstract: 1281888 Measuring areas photo-electrically KENT INSTRUMENTS Ltd 13 Oct 1969 [13 Sept 1968] 43749/68 Heading G1A The areas under a closed curve are measured by providing apparatus which can detect a difference in radiation at the boundaries of the curve so that when the areas are scanned an output representative of the distance between the differences can be summed to give a measure of each area. The area 10, which may be a record curve from chromatograph apparatus, is mounted in holder 28 and scanned by a beam of light from lamps 22 which is reflected on to the chart by rotating mirrors 26. Behind the chart are photo-cells 36 which detect the change in intensity of the transmitted light when it passes over the boundary lines of the curve. These changes operate respective ones of triggers 40 to on and off respectively so that during the on period the signal is integrated at 42. Synchronized with the rotation of mirrors 26 is a displacement device which moves the record 28 vertically one step for each sweep of light so that the whole area is scanned in parallel strips. Signals representative of the length of each strip are added in integrator 42 and presented on readout device 44. The signals may be analogue or pulses. In an alternative embodiment, Fig. 3 (not shown) the light source itself is rotated and the record again moved in steps perpendicular to the light beam. In this example a pair of photo-detectors is used to detect the change in the diffusing reflective property of the surface at the curve boundaries which are drawn using different coloured inks. Various alterations can be made in the construction of both embodiments to provide the scanning action. In a further embodiment the record may be placed adjacent the face of a cathode ray tube whose light spot is used as the source. A normal raster scan may be used or alternatively the record can be moved vertically and the spot scanned horizontally, Figs.4 and 5 (not shown).

Abstract: 1,169,948. Cathode - ray tube displays. WESTERN ELECTRIC CO. Inc. 13 Oct., 1966 [19 Oct., 1965], No. 45778/66. Heading H4T. In an arrangement for displaying images on the screen of a cathode-ray tube each image is built up from selected combinations of a plurality of different patterns each of which comprises a number of predetermined simple geometric figures termed " patches " common to a substantial number of patterns and the parameters of which are adjustable. Fig. 2A shows one such patch having a trapezoid-like shape which may be varied by variations of w (width), h (height), C 1 , C 2  (curvatures of opposite ends) and S 1 , S 2  (initial slope of opposite ends). Additionally, it may be rotated about the origin X 0 , Y 0  (Fig. 2B, not shown), and Figs. 3A and 3B illustrate the manner in which such figures may be utilized to form images. In the operation of the system (Figs. 4, 5, 6) numerical data specifying each pattern required by the entire display is derived from a store 10 together with an operational code for the system which initially controls the loading of font memory 25 with addressed information concerning the type font, size, shape &c. and the loading of sub-area memory 50 with addressed information concerning the parameters necessary to describe the patches in a particular sub-area. As the code pulses G1- G11 are produced the various operations indicated (Fig. 4) are effected, the pulse G6 serving to provide compensation for distortion of the pin-cushion type in the final reproduced image (Fig. 11, not shown). The outputs of the memories 25 and 50 are then utilized to control the production of the various beam deflections necessary for tracing each patch by means of a patch generator (Fig. 10, comprising Figs. 8 and 9, not shown), and to provide the other beam control functions indicated in Fig. 6. Each patch is reproduced as a " solid " figure by a series of left-to-right end right-to-left deflections (Fig. 2B, not shown) and on completion of a pattern which is indicated by a signal from memory 25 instructions for a subsequent operation are produced by register 21 (Fig. 4). The display may be recorded by photographic apparatus 71, 72 (Fig. 6) controlled by the operational code or by utilizing an arrangement in which the electron beam directly influences a recording surface. The invention may be employed in non-impact or in impact printing applications.

Abstract: 1,204,160. "Non-alcoholic" brewed beverages. ALLIED BREWERIES Ltd. Jan. 6, 1969 [Oct. 6, 1967], No.45895/67. Heading C6E. A process for the preparation of beverages containing a low concentration of ethyl alcohol involves fermenting yeast in a wort containing a source of nitrogen and a carbohydrate, the nitrogen content of the wort being between 10 and 30 mg N/litre and the specific gravity of the wort at the start of fermentation being not greater than 1À016, to achieve about half the total possible attenuation, removing rapidly the greater part of the yeast, subjecting the liquor to a second fermentation to effect still further attenuation and subsequently, after clarification, adding flavouring and sweetening materials including 3-10% by volume of conventional beer or ale. According to an example, 20 gallons of malt syrup are mixed in a wort boiling vessel with 20 gallons of corn syrup and water is added to bring the specific gravity to 1À090. The liquor is boiled with an extract of hops and transferred to a fermentation vessel where further water is added to dilute to specific gravity 1À013. The wort is pitched with a flocculating yeast (6 x10<6> cells / ml) and fermentation is carried out at 70 F. until the specific gravity reaches 1À007 when the liquor is cooled rapidly to about 55 F. for the yeast to settle, leaving about 1 x 10<6> cells/ml in suspension. The liquor is seperated off and the yeast concentration adjusted to 3-4 x 10<6> cells/ml. The temperature is raised to 70 F. and a second fermentation is allowed to proceed until the specific gravity has fallen to about 1À0045. The liquor is then chilled to 32 F. and finnings are added. Cane sugar syrup is introduced to bring the specific gravity up to about 1À007 and after standing to allow the sludge to settle and separation therefrom, the liquor is carbonated, blended with 5% light ale (to raise the spirit strength to a value approaching 2 degrees proof) and bottled.

Abstract: 1,043,681. Disc brakes. DUNLOP RUBBER CO. Ltd. Dec. 11, 1962 [Dec. 21, 1961], No. 45950/61. Heading F2E. In a caliper-type disc brake in which friction pad assemblies 21 supported by the caliper housing 12 are urged into frictional engagement with the disc by fluid pressure mechanisms associated with both sides of the disc, the torque taking edges of the friction pad assemblies are each supported on and guided by a detachable member 29 having a plane surface abutting the edge of a friction pad assembly and an arcuate surface 14 which is located against a cylindrical surface of the housing 12. The detachable member 29 may be in the form of a segmental torque-taking member of a suitable material such as ceramic material or treated in such a way such as by cadmium plating or the like, as to avoid corrosion, and the member 29 is located in the housing by means of bolts 37 or other suitable means. The friction pad assemblies 21 are axially slidable between the plane faces 31 of the members 29 and the radially inner end 32 of the members 29 is turned towards one another to form a step to prevent the friction pad assemlies 21 from moving radially inwardly. Radially outwards movement of the friction pad assemblies 21 is prevented by spring retaining members 33. The members 29 also serve as dampers to prevent or reduce squeal when the brakes are applied and by the choice of a suitable material they can prevent or reduce the transmission of heat from the friction pad material to the caliper. If necessary a thin lining of heatresistant rubber or the like may be fitted between the part cylindrical face 30 of each member 29 and the associated face of the aperture 14 which additionally serves to reduce squeal. In the further embodiment, Fig. 5 (not shown), the two torque taking members 29, one on each side of the friction pad assembly 21, may be combined to form a single member of substantially part-cylindrical shape. Reference has been directed by the Comptroller to Specifccation 818,077.
