Title: Means for carrying out bacteriological tests
Filed: 1955-09-19
Abstract: 779,514. Testing liquids and surfaces for bacteria. FORG, F. J. Sept. 19, 1955 [Oct. 4, 1954], No. 26704/55. Class 81(1) A device for testing for, and determining the density of bacteria in gases, or liquids or on surfaces, consists of a sheet or strip 1 of absorbent paper or absorbent plastic carrying a nutrient medium and any desired indicator, and packed in a sterile sealed container 2. The strip is removed from the container and dipped into the liquid or placed on the surface, under examination and may then be replaced in the sheath-like container 2 which, after the piece 5 of the strip which has been used as a handle is torn off, is then sealed and acts as an incubation chamber for the growth of colonies 17, Fig. 9 of bacteria recognized by the discolouration of indicator. To provide extra air for the growth of aerobic germs, the sealing seam 21, Fig. 13, of the sheath may be made at right angles to the seam 6 at the other end, while for anaerobic germs the air may be forced out before closing the sheath or the sheath may be made of material capable of being shrunk round the test strip. In testing for spores, the sheath may be of material resistant to sterilization temperatures. In testing liquids, the strip may be so made as to absorb an exact volume of liquid e.g. 0.1 or 1.0 ml., to enable the bacterial density in the liquid to be determined, and in counting the number of colonies where a thick strip is used, it may be made transparent, after incubation, by liquid paraffins or fats so that colonies inside the strip are counted. In testing liquids with a small bacteria density, a large sheet may be used so as to absorb 10 ml., and rolled up 22 with a separating foil 24, Fig. 17. In testing surfaces, the strip is initially sandwiched between two protective foils, Fig. 11 (not shown) one of which is peeled off before application to the surface and the other protects the strip from manual contamination while it is being pressed on the surface. In testing simultaneously for different bacteria, the strip is subdivided into sections each carrying different nutrient or indicator, Fig. 18 (not shown). In determining the effect of antibiotics of various, the strip is also impregnated with the antibiotic and a known germ such as thermobacterium bulgaricum seeded on to sections of the strip. Where highly coloured nutrients which may obscure colonies are used, the strip is covered with a thin microporous layer of cellulose which traps the bacteria so that the colonies will grown on the outside for ease of counting, Fig. 22 (not shown). Where viscous liquids, e.g. cream, are being tested, a stripper, Fig. 25 (not shown) is used to strip off excess liquid. Impregnating nutrient-indicator solutions for particular tests as of milk, water or excreta are given.

Title: Variable camber airfoil
IPC: B64C3/48
Filed: 1966-06-15
Abstract: 1,106,305. Variable camber aerofoils for boats, aircraft &c. E. M. WRIGHT. 15 June, 1966 [24 June, 1965], No. 26792/86. Headings B7B, B7G and B7V. A variable camber aerofoil for use as the sail of a boat or wheeled vehicle, the wings of an aircraft and for keels, rudders or propellers comprises a flexible skin urged into the shape of the aerofoil by at least one aerofoil forming assembly associated with a supporting structure 47, 49 disposed within the skin, the assembly being formed of a number of differently shaped plates interconnected by pivots, springs and links, whereby movement of the assembly causes different peripheral portions of said plates to engage the interior wall surface of the skin to thereby vary the camber of the aerofoil. To ensure that the skin is kept taut as the camber is varied, a spanwise strut 71 is urged by springs 83 and compression members (not shown), against the trailing edge of the skin. The skin is strengthened by spanwise extending channelled ribs 57 secured thereto by screws, Fig. 11 (not shown), opposed ribs being biased toward each other by a plurality of springs, Fig. 12 (not shown). When it is desired to vary the camber the forward strut 47 of the supporting structure is rotated. Rotation of the strut 47 causes a nose plate 107 of the aerofoil forming assembly to be rotated which initiates and causes movement of the other plates of the aerofoil forming assembly such as neutral plates 171, 173 and a tail plate longitudinally and rotatably movable about the fixed strut 49. When the aerofoils are used as a sail to propel a boat, Fig. 1 (not shown), two aerofoils are mounted vertically one behind the other, each on a separate turntable, the two turntables in turn being mounted on a larger turntable rotatable on a catamaran-type hull. The hull is provided with a cockpit from which the rotation of the turntables and the variation in aerofoil camber are controlled.

Abstract: 1347118 Contact printing apparatus KALLE AG 19 April 1971 [16 April 1970] 26916/71 Heading G2A A contact copying apparatus comprises a rotatable copying cylinder 21 and first, second and third feeding devices e.g. belts 13, 14 and 15, for feeding an original and copying material through an exposure zone positioned around part of the periphery of the cylinder, characterized in that a light beam 18 is screened out of a copying light source 19, passes through a transfer zone positioned between the first and second feeding devices and strikes at least one photo-electric cell 20, the light beam being modified by the passage of the original therethrough and serving to control one or more of the following (a) selection of copying material of an appropriate width (b) selection of copying material of an appropriate length (c) selection of an appropriate exposure time and (d) alignment of the copying material with the original. The original 10 enters the apparatus at a slit 12 and is fed from the first 13 to the second 14 feeding device, which are in the form of endless belts, across a light-impermeable plate 16 having a transverse slit 17 through which the light beam 18 passes. As the original cuts the beam 18 the photo-cell, or bank or photo-cells 20 register (a) the width and front and rear edges of the original, thus determining the length and width of copying material required; (b) the transparency of the original, to determine the copying speed; and (c) the positioning of the lateral edges of the original to determine any lateral displacement of the copying material required. The copying material is fed from rolls 41, 42, 43 of varying widths housed in a casing 40. A sheet 23 of the determined width and length is automatically cut and fed on to a belt 46. The belt 46 is supported on a carriage 45 which may be displaced laterally in dependance on the measured displacement of the original, so that as the original 10 and sheet 23 meet at the nip 22 between belt 14 and a belt 15 forming the third feeding device, they are exactly superimposed. The belt 15 conveys the sheets around the copying cylinder 21. After exposure the original and copy are separated, the former being ejected into troughs 29 or 31 and the latter passing to a further belt 32 which conveys the copy through a development section 36 and ejects it into troughs 38 or 39. The belts 13, 14, 15, 32, 46 may consist of a single perforated belt or a plurality of parallel belts. They are air permeable and the cross hatched regions indicate areas of suction for retaining the original and copy on the belts. In an alternative mode of operation the direction of the belts is reversed and an original 50 superimposed on a copy sheet 51 is fed manually from a desk 49 directly to the exposure zone without the original passing through the light beam.
