Title: Oxidation of cyclohexane
Inventor: SEDDON WILLIAM LESLIE
Filed: 1961-12-28
Abstract: <PICT:1039092/C2/1> In the manufacture of cyclohexanol and cyclohexanone by oxidizing liquid cyclohexane with an oxygen-containing gas, condensing unreacted cyclohexane vapour in the residual gases leaving the reactor and returning the condensed cyclohexane to the reactor, the mixture of residual gases and cyclohexane vapour leaving the reactor is subjected to indirect heat-exchange with oxygen-containing gas being supplied to the reactor so as to condense at least a part of the cyclohexane vapour, the arrangement being such that, at the same time, liquid cyclohexane supplied to the heat-exchanger with the oxygen-containing gas is vaporized. As shown, residual gases and unreacted cyclohexane vapour pass from a reactor 1 through a pipe 2 to a heat-exchanger 3 containing tubes 4, from which the mixture passes through a pipe 5 to a condenser 6 and thence to a separator 8. The condensed cyclohexane then passes by a pipe 9 in part to a pipe 15, through which fresh cyclohexane is fed to the reactor, and in part through a pipe 18 to a spraying nozzle 19 in a pipe 17 through which oxygen-containing gas is supplied successively to the heat-exchanger and the reactor, which it enters via a pipe 20. The reactor may be associated, as described in Specification 1,025,752, with a reboiler 22 in which unreacted cyclohexane is partly vaporized.

Filed: 1966-10-18
Abstract: 1,125,272. Proximity detectors. CONTINENTAL CAN CO. Inc. Oct. 18, 1966 [Jan.10, 1966], No.46590/66. Heading G1N. Apparatus for inspecting electrically conductive flexible lids on vacuum sealed glass food containers, comprises two coils E 1 , E 2  connected in a "proximity detector" bridge circuit for sensing the arrival of a container at the testing station, two coils D 1 , D 2  connected in a "position detector" bridge circuit for sensing when the container is in a predetermined position at the testing station, and three coils A, B, C for sensing the profile of the container lid. If the lid's profile is outside predetermined limits, the container is automatically rejected. Coils A and C have equal numbers of turns and are connected in series aiding relation in one arm of a "dud detector" bridge circuit and coil B having a number of turns equal to the sum of the turns of coils A and C, is connected in a second arm. Coils A and C provide compensation for allowable variations in height of the containers and for any tilting of the containers. When a dud is detected, transistor Q 4  is rendered conductive to trigger a one-shot multivibrator Q 5 , Q 6  to energize a relay 93 to admit air to ejector 18 to push the container down chute 17. Resistor R 2 , in a voltage divider chain R 3 , R 1 , R 2 , is normally short-circuited except when the proximity detector bridge is unbalanced and the position detector bridge is balanced, whereby unbalance of the dud detector bridge can trigger transistor Q 4  only if a container is properly positioned in the predetermined position at the testing station. The coils may be mounted within a steel housing provided with heating coils (54, 55) and arranged to be pivoted out of the way if too high a container contacts a ramp (58) on the underside of the housing. Magnetic shielding (53) may be provided between the coils A, B, C and coils D 1 , D 2 , E 1 , E 2

Title: Improvements in or relating to blind-riveting tools
IPC: B21J15/26
Filed: 1962-12-21
Abstract: 949,300. Blind-riveting machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. Dec. 21, 1962 [Dec. 28, 1961], No. 48497/62. Heading B3U. A blind-riveting tool comprises a jack screw device, one member of which is arranged to be driven by power means including a clutch, mandrel-pulling means associated with the other member of the jack-screw device, trigger means to cause the clutch to be engaged, and means actuated by the mandrel-pulling means at the end of its stroke to disengage the clutch and restore the trigger means to its unpressed condition. The main body portion 10 of the tool houses the reduction gearing, clutch and jack screw mechanism and has attached to it a motor, a handle 12 and a detachable nosepiece 14. The nosepiece contains mandrel-engaging jaws 16, a slide bolt 20 and a pull bolt 22 which is secured by a screwed cap 25 to an axially slidable but non-rotatable nut 26. The nut is assembled with a screw 30 and there are friction reducing balls between the two members. Keyed to the screw 30 is a gear-wheel 38 which is in constant mesh with a driven clutch member 60. The driving clutch member 54 is mounted on a splined shaft 52 which is positively driven by the motor through the reduction gearing. The clutch member 54 is actuated by a bell-crank 78 which is linked to a trigger 64 by a vertically sliding member 76. The trigger also operates a normally closed micro-switch 72 and is biased to the " OFF " position by a spring 68. The clutch members have radial inter-engaging teeth and during a rivet-setting operation the torque transmitted by the clutch causes sufficient friction to hold the clutch parts together even if the trigger is released. When the rivet-setting mandrel fractures the reduction in friction allows clutch members to part under the influence of the spring 68 and the tool is switched off. Alternatively, if the nut 26 proceeds to the limit of its travel before the load reduces a cam face 92 on a block 44 attached to the nut engages a face 94 on the vertical member 76 and operates the bell-crank 78 to disengage the clutch, and the trigger 64 to stop the motor. The screw 30 is driven in reverse rotation to return the nut 26 to its starting position by a torsion spring 42 which is tensioned during the working stroke. Specifications 348,818, 405,993, 459,973, 504,928, 578,104 and 587,938 are referred to.

Abstract: 1, 083, 499. Automatic speed control. AMERICAN BOSCH ARMA CORPORATION. Dec. 1, 1964 [Dec. 2, 1963], No.48700/64. Heading G3R. [Also in Division F1] The speed of an engine, above a predetermined range, is controlled or limited by solenoid adjustment of the throttle or its maximum opening stop in response to electrical signals whose frequency is proportional to speed. The speed signal is derived from a transformer (72) Fig. 1 (not shown) in series with the engine ignition coil and contacts, or from a magnetic pick-up associated with the engine shaft; it is fed to a series L/C circuit (78, 80) resonant just above the desired speed so that the system operates on the steep part of the characteristic. The output across a resistor (82) is rectified and smoothed to produce a D. C. speed signal, which is amplified by silicon transistors and applied to the throttle solenoid; this either counteracts a spring biasing the throttle open or moves a throttle stop. The transistors have a threshold below which they do not conduct, and this is not reached until the speed signal frequency reaches the steep part of the L/C circuit characteristic. The desired speed is set by adjustment of either the inductor or the capacitor.
