Title: Stereoscopic Display System.
IPC: G01R13/20
Filed: 1967-03-06
Abstract: 1,178,298. Cathode-ray tube displays. INTERNATIONAL BUSINESS MACHINES CORP. 6 March, 1967 [11 July, 1966], No. 10382/67. Heading H4T. In an arrangement for producing a stereoscopic display of an image element the three co-ordinates of which are supplied from a data source, the spacing of the stereoscopic pair of image elements in the display is determined by the "depth perspective ratio", i.e. the ratio of the distance normal to the display surface of an effective viewing point to the sum of this distance plus the distance normal to the display surface of the "in space" position of the element the position of the image points being additionally controlled by perspective control means to enable a perspective view from various directions to be obtained. The display may be on a paper surface, a projection screen or the screen of a cathode-ray tube. In the case of the latter a single or double beam tube may be employed or two separate tubes, one for each eye view, may be employed. The described embodiment of the invention utilizes a single beam tube. Referring to Fig. 1, which shows a front view of the display surface in the X, Y plane and a side view in Z plane, the points NL and NR termed respectively, the left and right "vanishing points" represent the orthogonal projections of the left and right viewing points (e.g. VP repesents the right viewing point) on the display surface, the points L and R represent the stereoscopic pair images of the element D (having co-ordinates X, Y and Z) and the distance G, termed the "line of sight distance", is the distance from the "vanishing points" to the orthogonal projection of the element on the display surface. Utilizing the geometrical considerations shown circuits means (Fig. 2, not shown) supplied with the X, Y and Z co-ordinates of the element D derives deflection signals to position the display tube beam at the stereoscopic pair points L, R. The effective eye base K, which may have any value, since an optical viewing device is utilized to separate the left and right eye views and to convert the effective eye base to the approximate actual eye base of the observer, may be varied by perspective control means which varies the X and Y co-ordinates of the left "vanishing point" NL, the point NR being fixed, to enable the display to be viewed from other perspective positions. Additionally, means are provided for producing the effect of "zooming" by adding or subtracting a constant to the Z co-ordinate of the data and/or producing "depth exaggeration" by multiplying the Z co-ordinate by a constant. The X and Y co-ordinates of the stereoscopic pair points L, R for a succession of elements are first assembled and then cyclically supplied to the tube deflection means together with a bright-up pulse to produce a visible spot of short duration when the beam has been positioned at the required L and R points. The optical viewing device may utilize polarized or coloured light filters or other known devices to separate the left and right views.

[Class 83 (iii)]  A tool-carrying device for automatic lathes comprises a pivotally-mounted. tool-spindle carrier, at least two toolspindles mounted in the carrier for axial movement therein and is characterized in that the tool-spindles are provided with separate means for effecting axial movement thereof, each said means being adapted to be retained in connection with its spindle in use and comprising universally-jointed couplings, the means for effecting axial movement of the tool spindles and pivotal movement of the carrier being interconnected so as to be actuated simultaneously. The carrier 15, Fig. 3, having two tool-spindles 16, 17, is rockable about a pivot 12, Fig. 4, to bring each tool-spindle in turn into the axis of the stock 14 carried in a spindle 70. A spring 27 maintains a face 22, Fig. 4, on the carrier in contact with a roller 20 secured to one arm of a double lever 24, the other arm of which engages a cam 25 on a main cam-shaft 26. Stops 31 are provided on the carrier to engage fixed lugs 30 on the machine frame to ensure alignment of the spindles with the work in each indexed position. The spindles are fed axially from an auxiliary cam-shaft 55 driven by bevel gearing from shaft 26, the cams 56, 57, operating through levers 36 and 51, respectively, on the ball-ends of push-rods 43, 49, the other ends of which engage similarly with collars 39, 38, secured to the tool spindles. The push-rods are held between the lever ends and collars by tension-springs 46, 52. The spindles may be adapted to rotate, in which case a gear-wheel driven through belt means from the main spindle drive is arranged on the axis 12 and engages toothed wheels splined to the tool spindles. Adjustable stops 62 are also provided to limit the rearward motion of the camactuated levers for the axial feed of the spindles.

The threads are of the same hand and the direction of rotation of the barrel is selected so that thread 21a tends to cause travel of the mass in the barrel down wall 17a and across bottom 17b towards column 20 while thread 22a tends to cause travel of the mass upwards along the column 20, producing a circulation. A spindle 12 mounted by bearings 11 in a frame 10 has an extension 18 received in a central bore in the column 20 and a disc 14 provided with a rubber washer 15 engaging a washer 16 let into the bottom plate 17c of the barrel. An alternative form of barrel is shown in Fig. 3. Apparatus suitable for use in barrelling small quantities of different parts comprises a closed base structure 40, Fig. 4, housing motors for driving banks of driving devices, including friction discs 14 and spindles 18, projecting from an inclined top surface 40a of the base. The base structure is fitted with tilting drawers or bins 42 for storing abrasive in nugget form, trays 44 for storing abrasive in tablet form and washing lockers 43. The barrels 41 are constructed as previously described. Specification 855,865 is referred to.

Title: Improvements in or relating to preparing fried potato products
IPC: A23L19/18
Filed: 1961-03-24
Abstract: A fried potato product is produced from raw white potatoes by preparing an extrudable, moist mixture consisting essentially of potato cells which are intact, potato cells which have been ruptured and the starch contained therein, and a thermal gelling binder, effecting solvation between the binder and the mixture by maintaining the binder and the mixture at a temperature not exceeding 90 DEG F., shaping the resultant product and deep fat or French frying the shaped product.  The mixture may include dehydrated potato particles which have been rehydrated in the presence of the binder.  A prepared mixture adapted to be stored dry and subsequently deep-fat fried, consists essentially of 5-35% crushed dehydrated potatoes, 95-65% ground potato flakes and 1-8%, based on the total weight of potato solids, of an edible thermal p  gelling binder distributed throughout the mixture, between 20% and 30% of the potato solids thus having ruptured cells; the ruptured cell content may be obtained by mixing, by extended cooking, by employing small cut up pieces of potato such as undersized pieces normally removed from standard French fried production or by adding dry ungelatinised potato starch.  The mixture may include also seasoning (salt), cheese or onion flavourings, added starch (preferably potato starch), monoglycerides and non-fat dry milk solids.  If desired, the shaped product may be partially fried, subjected to cold storage and again fried or baked when required for use.  Thermal gelling binders: cellulose ethers, including methyl cellulose ethers, and the propylene glycol ether of hydroxymethyl cellulose; and pectinates, caseinates, alginates and wheat gluten when a dehydrated mix is employed.  Potato products: French fried potatoes, potato patties, croquettes, chips, shoe-strings and other crisp snack items, and special forms of product such as round or elongated French fried potatoes and croquettes shaped as a baked potato.  Examples directed to the production of the fried potato products are given.  Specification 985,809 is referred to.
