Abstract: 1353961 Fruit cutting appliance A BORNER 7 Oct 1971 [22 Oct 1970] 46719/71 Heading A4C A cutting appliance for tomatoes or other fruits comprising stationary, parallel-disposed blades 2 which are fixed in a frame 1, said frame consisting of two partially open end-walls 3, which are V-shaped in end view, and connected together by two longitudinal supports 4, 5 and the saw blades extending between them. The blades are arranged in juxtaposition and offset from each other in stepped formation so that the cutting edge (6) Fig. 2 (not shown) of each adjacent blade 2 is approximately at the height of the bottom edge (7a) of the guiding surface (7) of the blade above it and thus ensures that individual separated slices of fruit are unable to move laterally until the subsequent cut has commenced. The guiding surface (7) of the saw blades are substantially parallel to the plane of symmetry of the V-shaped frame in end view. The blades may be wedgeshaped in cross-section with a recess (9) on the underside thereof and have a guide surface extending obliquely outwards for guiding slices which are severed from the fruits, or may approximately take the form of a parallelogram in cross-section Fig. 3 (not shown). Formed on one end-wall 3 of said frame is an outwardly projecting guide arrangement (14) with a groove (15) which accommodates an axially displaceable, shaped rod (16). Pivoted on one end of the rod is a fruit pressing device (19) having an underside which is generally convex and supports sets of pins (22), (23) Fig. 6 (not shown) of different lengths in order to press the fruit securely and downwardly into the slicer. A handle (20) is supported on the devices upper side. The guide arrangement (14) also forms a handle for the frame 1 so that the entire cutting appliance, of which the fruit pressing device and slicer may be formed separately by injection moulding synthetic plastics material, may be handled easily. The initial cutting is made manually and it is only when the fruit is substantially cut by a reciprocal action that the fruit pressing device is utilized in order to cut the last remains of the fruit without danger of injury to the user.

Title: Photoconductive recording materials
IPC: G03G5/05
Filed: 1961-12-29
Abstract: The dark resistivity of zinc oxide particles is increased by contacting the particles with at least one ionic organic phosphorous compound so that absorption of the compound(s) takes place at the surface of the zinc oxide particles. It is thought that absorption takes place through interchange of zinc ions from the oxide with the cationic atom or group of the phosphorus compounds.  A list of suitable acidic oxygen-containing phosphorus compounds is given in the Specification.  Salts of these compounds may also be used, the cation being a metal ion, an ammonium ion, or a quaternary ammonium ion.  Various classes of organic compounds are suggested for use in combination with the phosphorus compound to treat the oxide.  These classes include certain aliphatic mono- and poly-carboxylic acids, their salts, and anhydrides; aliphatic mono- and polysulphonic acids and their salts; aliphatic boric acid compounds and their salts; aromatic mono- and poly-carboxylic acids and their salts and anhydrides; and aromatic sulphonic acid compounds and their salts. The phosphorus compound(s) with or without additional compounds from the classes above will be termed a "treating agent."  The zinc oxide particles may be contacted with the treating agent in the following ways:  the zinc oxide may be exposed to a gaseous form of the treating agent; the treating agent may be added to an aqueous or organic dispersion of the oxide; or the zinc oxide may be dispersed in a binder solution and used to form a photo-conductive layer on a backing which comprises a layer containing a sufficient concentration of treating agent to ensure that the treating agent diffuses into the zinc oxide layer during the coating operation or during storage prior to use-alternatively the treating agent may be allowed to diffuse from a layer applied over a resin-bound layer of zinc oxide.

Filed: 1974-10-09
Abstract: 1481517 Radar EMI Ltd 9 Oct 1974 [10 Oct 1973] 47387/73 Heading H4D In a synthetic aperture radar incorporating phase correction to the video signals to compensate for lateral deviations of the aircraft from a presumed course, it is assumed that the target T is on a "flat Earth plane" ON Fig. 2, e.g. for a range call r target T is mistakenly assumed to be at N. When horizontal and vertical aircraft deviations (provided by double integrating accelerometer outputs) are thus incorrectly resolved along line ON instead of line OT, the resultant phase correction is also incorrect. To overcome this, Fig. 3, for each of the n range cells (the r<SP>th</SP> cell channel 2r is shown) phase corrections are applied for the assembled angle # 1 =O‰N and for (# 1 +1‹) and for (# 1  - 1‹). The three phase corrected video signals from circuit 3 are fed to a correlator 12 for comparison with a reference and a comparator 14 determines which phase correction yields the maximum correlation. The correct angle (# 1 +E)=OAT is thus determined and stored at 15 for use on the video signal. To increase the S/N ratios, the correlation comparison may be performed over several, e.g. five adjacent elevation cells, using integrators 13 and/or over several adjacent range cells. If an M.T.I. circuit is incorporated as described in Specification 1,481,414 and using a delay cancellor, the comparator 14 needs to seek a minimum rather than a maximum.
