Title: Improvements in or relating to the production of monoesters of ascorbic acid
IPC: C07D307/62
Filed: 1943-09-16
Abstract: Mono esters of ascorbic acid are prepared by reacting this compound with a saturated aliphatic monocarboxylic acid in the presence of sulphuric acid as an esterification catalyst and solvent for the reaction products.  The reaction is preferably carried out at room temperature or lower, to avoid decomposition. In examples: (1) a mixture of ascorbic and lauric acids are dissolved in 95 per cent sulphuric acid, allowed to stand at room temperature and poured on to ice.  The product is then extracted with ether, dried and washed with petroleum ether.  (2) Ascorbic acid is esterified with myristic acid as in example (1).  (3) Ascorbic acid is esterified with palmitic acid as in example (1). (4) Ascorbic acid is esterified with stearic acid as in example (1).  (5) Ascorbic acid is esterified with caproic acid as in example (1).  (6) Ascorbic acid is esterified with 9 : 10-dihydroxystearic acid as in example (1).  It is stated that an important result of the process of the present invention is that the esters formed retain the characteristic properties of compounds containing an unsubstituted ene-diol group.  The compounds of the invention have valuable anti-oxidant properties and are particularly suitable as anti-oxidants for edible fats.

Title: Automatic numeric machine tool control systems
Inventor: RHOADES JOHN MERRILL
IPC: G05B19/416
Filed: 1968-03-29
Abstract: 1,217,961. Programmed control of machine tools. GENERAL ELECTRIC CO. March 29, 1968 [April 24, 1967J, No. 15315/68. Heading G3N. A numerically controlled machine tool control system, having a pulse rate modifier comprising a commanded rate register and an interconnected multiplier, is provided with one or more sensor of the physical condition of the tool or workpiece which, through logic circuitry, modify the action of the multiplier. As shown, data relating to a machining operation is read from a tape or punched cards and fed from a unit 19 into an electronic control 20 wherein the pulses from a clock 21 are converted in a unit 26 into a pulse train representative of a commanded feed-rate as modified by a manual feed-rate override 25. The feed-rate pulse train is transformed in a function generator 22 into X and Y axes co-ordinate velocities which, through servo-controls 12, determine the operation of X and Y axes feed drives 23, 24 positioning an element of a machine tool 18. The feed-rate is modified in response to selected ones, or combinations, of the sensed values of vibration, from sensor 27; temperature, from sensor 28, and torque, from sensor 29, through switch contacts 30d-30f of a selector 30. The selected values are fed through diodes 333 to an algebraic combiner 34 in which they are compared with a reference value from a source 38 connected by switch contacts 70a of a selector 70; alternatively the sensed values are compared with corresponding reference values sources 45-47 connected by switch contacts 30a-c of the selector 30. The error between reference and sensed values is applied through an operational amplifier 48 to level sensors 50-53 which determine the sign of the error and whether it is greater than first and second limits. The error level signal from the sensors 50-53 control a pulse-rate selection logic 54, connected to the clock 21 through pulse-rate dividers 55, 56 a pulse rate line 59 and a count up or count down signal on line 61, 62 which alters the feed-rate, from the overide 25 to the unit 26, in a modifier 60. The modified feed-rate, through a digital to analogue converter 67 is additionally applied to a control spindle drive 65. The choice of direct, or modified adaptive control is determined by switch contacts 63a, 63b of a selector 63. When the degree of modification exceeds a set value a switch control 69 opens a contact 69a to terminate the operation of the machine tool.

Filed: 1950-06-21
Abstract: 705,902. Photographic roll film cameras. HEIDECKE, R., [trading as FRANKE & HEIDECKE]. June 21, 1950 [June 23, 1949], No. 15503/50. Class 98(1) An exposure gate for a roll film camera including a presser plate carried by the camera back and spring-urged against the exposure frame to form a channel for the film is characterized in that the plate or the frame is provided with projections which, upon movement of the plate in a direction parallel to the plane of the film, engage with complementary parts of the frame or plate respectively to vary the thickness of the film channel. As shown, a presser plate 9 carried by screws 12, 13 with their shanks passing through slots 14, 15 in stirrups in the camera back is urged towards the fixed gate members or exposure frame 2 by springs 10, 11 and against stops 16 disposed. outside the film runners 5, 4 to define a film channel for an ordinary roll film. If a thinner roll film, e.g. one without a backing paper is to be used, the presser plate is moved downwardly so that slots 17 therein register with the stops 16 and so defines a thinner film channel. If a miniature film without backing paper is to be used, a miniature film gate 18 is inserted between the film runners 3, 4 on which the miniature film gate is supported by ears 21 with the film supporting faces of the runners 19, 20 of the miniature film gate co-planar with those of the runners 3, 4, the smaller gate carrying curved extensions 33 which cam the plate 9 downwardly as the back cover of the camera is closed to define the required thinner film guide channel. If films of more than two different thicknesses are to be used, the stops 16 may be formed with steps of different heights, or the presser plate 9 may have steps of different heights co-operating with a fixed part on the exposure frame 2. In a modification, Fig. 3 (not shown), in which only the presser plate moves relative to the camera back wall, the centres of the presser plate springs are bolted to the camera back, the head of each bolt being located in a slot on the far side of the plate which is held in a selected position by a projection on each spring engaging one of a number of corresponding recesses in the rear face of the plate.
