Patent GB-797611-A (GB)
Title: Improvements in and relating to the preparation of ketoximes
Filed: 1955-10-12
Abstract: 797,611. Electrolytic preparation of ketoximes. WILSON, C. L. Oct. 12, 1955 [Oct. 14, 1954], No. 29025/55. Class 41. Ketoximes are produced by cathodically reducing a solution of an inorganic nitrite or nitrate in the presence of an aliphatic or cycloaliphatic ketone at pH 5 to 11. The temperature should be kept below 70 C. for satisfactory yields and typically is around 10 C. The solution should be agitated as by use of a cylindrical cathode rotated perpendicularly to its axis. The cathode is preferably of zinc although lead, magnesium, copper, nickel, or platinum may be used. In practice the solution contains 10- 20 per cent of the inorganic salt and if a diaphragm of unglazed porcelain is used to form a cathode compartment, the catholyte pH is maintained close to neutral by passing CO 2  through it or by adding buffers such as dipotassium hydrogen phosphate or sodium acetate, ethyl alcohol, and ethyl acetate. An alcoholic instead of an aqueous solution may be used, while other solvents suitable are dimethylformamide, dioxane, and ethylene glycol.

Title: Unconsolidated formation core barrel
Inventor: HILDEBRANDT ALEXANDER B
IPC: E21B25/06
Filed: 1958-09-12
Abstract: 842,302. Core cutting apparatus. JERSEY PRODUCTION RESEARCH CO. Sept. 12, 1958, No. 29267/58. Class 85. Coring apparatus is characterized in that a resilient sleeve is provided to catch the core. The apparatus comprises an outer barrel 2 splined to a pipe string 3 so that it is free to move axially but rotates with the string. An inner barrel 12 is supported inside the outer barrel by a bearing 34 so that relative rotation can occur between the barrels. The inner barrel is double-walled, the inner wall 22 supports one end of a resilient sleeve 17 which is doubled back on itself and secured at its other end to a plug 21 which is suspended by a rod 6 from the pipe string. A bearing 20 permits relative rotation between the plug and the outer barrel. The outer wall 23 of the inner barrel terminates in a shoulder 24 which guides the sleeve 17 and the core 25. Drilling fluid is pumped down the pipe string, passes through the apertures 8 and through the ports 10 in a plate 15. There is a pressure drop in the fluid in passing through these ports and the resultant pressure on the the upper surface of the plate 15 drives the outer barrel downwards. The fluid subsequently passes without pressure drop through a clearance 18 between the rod 6 and the outer barrel 12 and is used to inflate the sleeve 17. The maximum diameter to which the sleeve can be inflated is restricted by a non-extensible external layer of a smaller diameter than the inside of the outer wall 23. A port 19 between the chamber 27 and the annular passageway 35 allows drilling fluid at a pressure P3 which is smaller than P2 to reach the chamber 27. In operation the outer barrel 2 rotates and drives the core cutter 1, the inner barrel 12 and the plug 21 remain stationary and as the inner and outer barrels advance, the sleeve 17 passes under the lower edge of the inner wall 22 of the inner barrel and encloses the core 25.

Title: Improvements in processes for the disinfestation of vegetable products by means of toxic gases
IPC: A23B7/152
Filed: 1955-10-19
Abstract: In a process for the disinfestation of vegetable or fruit products by means of toxic gases acting in an enclosed space containing the products to be disinfested, use is made, as a carrier for the toxic gases, of a mixture of gases adapted to enhance the physiological activity of the insects to be destroyed relative to their physiological activity in the free atmosphere and, thereby, to increase their capacity for absorbing the toxic gases, the concentration of which is kept within the limits of non-toxicity for the vegetable and fruit products.  The mixture of gases may be rich in oxygen, e.g. 55 per cent and is particularly used for the destruction of perfect insects, or in the case of the destruction of imperfect insects the carrier may be rich in nitrogen, e.g. from 90 to 95 per cent.

Abstract: 1472561 Measuring the widths of articles EMHART INDUSTRIES Inc 8 July 1974 [9 July 1973] 30081/74 Heading G1A An article inspection system Fig. 1, comprises a conveyer 10 of articles A, a generator 18 providing pulses proportional in number to the conveyer displacement, stationary photo-cell 22 for generating a 'diameter pulse' which lasts while an article passes, a counter 32, 34 of the number of pulses during this time, means 50 for providing a reject pulse 58 when the number of pulses counted is not within a certain range, and station 14 responding to pulse 58 to reject the article. NAND gate 26 gives an output of pulses while the diameter pulse lasts. Switches 40 and 42 are for pre-setting the count value at which a pulse is provided via NAND gates 36 or 38 to device 50, which does not give a pulse 58 when there is a signal 48 and no signal 56. Pulse 58, which may be delayed operates an air nozzle in station 14. In another embodiment Fig. 2 capacitor C, produces an interogate pulse 150 from the end of the diameter pulse from line 24 by differentiation. When the article has a diameter pulse count less than the minimum set at 141 and 143, MIN memory 144 provides a pulse so that with pulse 150 the output of NAND gate 136 ceases and NAND gate 156 gives a reject pulse 158. Similarly when the pulse count is greater than the maximum, MAX memory 155 provides an output and gate 156 gives a pulse 158.
