Title: Improvements in jacquard mechanism for looms for weaving
Inventor: FIELDING ANTHONY BIRCHENALL
IPC: F16H19/08
Filed: 1961-07-20
Abstract: 944,825. Jacquard mechanisms. DEVOGE & CO. Ltd. July 17, 1962 [July 20, 1961], No. 26246/61. Heading D1E. The griffes of a Jacquard mechanism are operated by a lever a which is connected via rods b<1>, b<2> to one end c of a connecting rod C, the other end c<1> of which is eccentrically pivoted to a planet gear D which revolves round a sun gear E. Due to the eccentric mounting of the connecting rod C its end c<1> describes an ellipse and hence between positions 2 and 3 and also between positions 5 and 6 the lever a remains substantially stationary and a dwell is imparted to the griffes. The end c<1> is mounted in a diametral groove on the gear D so that the eccentricity and hence also the length of dwell may be adjusted.

Title: Improvements in telescopes
IPC: G02B27/32
Filed: 1927-10-05
Abstract: 279,069. Naamlooze Vennootschap Nederlandsche Instrumenten - Cie. Oct. 12, 1926, [Convention date]. Telescopes. - For use by artillery observers situated in an observation aeroplane, telescopes are fitted with displaceable graticules consisting of two groups of lines one of which is formed of parallel straight lines having intervals corresponding to the angular values. The other group consists of curves the distance of which from a perpendicular to the first group of lines are proportional to the cosines of the angular values. The telescopes so fitted are used for measuring the position of the impact of projectiles according to two co-ordinates perpendicular to each other relatively to a target fired at by the battery. A carrier 3 is fitted to the left-hand objective of a binocular telescope and is maintained in correct position relatively to the axes of the instrument by a fork embracing the mount of the other objective. To the carrier 3 is fitted a casing 9 carrying a pendulum body 11 on which is fixed a curved graticule, Fig. 5, and also lenses 16, 17 by which the graticule is projected into the focal plane of the eyepiece of the telescope. The straight lines on the graticule correspond to angles whose tangents are round figures, so that by placing the target on the central line, its projected distance from the observer is given by multiplying his distance above the ground by the tangent of the angle indicated. The position of impact is given by reading off the distance forward or from the target and the lateral deviation is determined by reading the cosine curves and multiplying the reading by the distance above the ground of the observer. Mathematical proof is given in the Specification. In a modification, Fig. 6, a plane graticule 35 is utilized in a telescope which is supported in gimbals 24 and maintained vertical by sighting an axial mark 36 in the field lens 26 so that it coincides with the image of a mark 38 freely supported on a pivot, the latter mark 38 being projected into the telescope through a prism 39, lens 40, prisms 41, 30 and lens 25. The target and impact position is sighted through a rotatable entrance prism 29 situated simultaneously with the graticule by the handle 32, so that the graticule moves appropriately to the angle at which the target is sighted. The distances are calculated in a similar manner to that of the first example.

Patent GB-1012405-A (GB)
Title: Glucose production
IPC: C13K1/10
Filed: 1963-07-08
Abstract: Glucose is produced by hydrolysing starch to convert it to glucose, clarifying the hydrolysate, evaporating the hydrolysate to a solids content above 88% by weight, mixing the concentrated hydrolysate with a gas and subjecting the concentrated hydrolysate to a shearing stress whereby solidification of crystalline glucose is achieved, and recovering the solidified glucose. The gas used is any gas which is inert to the concentrated hydrolysate, e.g. air, nitrogen and oxygen. The starch is hydrolysed by means of a mineral acid or microbiological enzymes. Before concentration the hydrolysate may be purified by treatment with ion exchange resins. The shearing stress is preferably applied by means of gear type pumps in which the concentrated hydrolysate is subjected to a shearing action by the meshing gears.
