Title: Advance mechanism
IPC: G03B21/11
Filed: 1972-10-11
Abstract: 1396897 Film advance mechanism XEROX CORP 11 Oct 1972 [18 Oct 1971] 46894/72 Heading G2A Variable precision advance mechanism for imperforate film is in the form of an output rotor 16 driven in one direction only by a reversible motor 14 by means of a transmission system comprising a forward direction one way clutch 22, friction clutch 24 (for the reverse direction), timing belt 32, input member 34, electromechanical clutch 38 and electro-mechanical brake 48. The length of the advance is determined by the angular movement of a metering arm 54 (integrally connected to input member 34) between a stop 56 and a micro-switch 58 (integrally connected to a worm wheel 60 by an arm 61). Closing of micro-switch 58 actuates brake 48, de-energizes clutch 38 and effects reversal of motor 14. Timer means de-energizes motor 14 after metering arm 54 has returned to stop 56. The position of microswitch 58 (and hence the length of the film advance) is adjusted by means of a worm 62.

An electronic elapsed time meter for registering hours of operation comprises a transistorized circuit, which is energized or de-energized when the ignition switch 19 of an I. C. engine is closed or opened and includes a relaxation oscillator 10 having a unijunction transistor 15 with a Zener diode 22 coupled thereto to regulate the supply voltage.

Abstract: 1, 033, 708. Suturing appliances. J. E. HEALEY and E. B. MOORE. Dec. 20, 1962 [Dec. 26, 1961; Aug. 7, 1962], No. 48134/62. Heading A5R. [Also in Division E2] An instrument for holding together cut ends of body ducts e.g. blood vessels, for suturing, comprises cylindrical clamping bodies 26 mounted on pivotal arms A, B, each body having a circular channel therethrough for receiving a cut end of a body duct and comprising two parts which on separation afford a passageway between the channel and the exterior, the bodies defining working surfaces which as they approach one another, on finger manipulation of the arms, first make contact at a point furthest from the pivot, and the channels, in the final position of the working surfaces, having their axes coincident. Arms A,B, each having a handle 20 at one end and a cylindrical axially bored head 26 at the other, are pivotal intermediate their ends so that, when the handles are brought together, the heads are axially aligned. A cylindrical bushing in two separable complementary parts 64, 66 is inserted in the bore of each head so that faces of flanges 68 of the bushings face one another and a slot 62 in each head is closed. In use, the arms are separated at the pivot and cut ends of a body duct to be sutured are passed one through each bushing and cuffed one over each head, where they are secured by rubber rings. The arms are then reassembled at the pivot and the handles are pressed together so that the cuffed ends of the body duct abut one another. The arms are secured in closed position by the interengagement of toothed projections 24 which extend from each arm adjacent the handle, the teeth of the projections being disposed so that on engagement a suitable predetermined pressure is applied to the abutting ends of the body duct. After removal of the rubber rings, the cuffed ends of the body duct are sutured together. To remove the device, the handles are opened, the arms are separated and the bushings are removed from the heads so that the duct may be slid through the slots 62 in the heads. One arm B has a flattened central portion 44 with overhanging flanges 50, 52 and a pivot pin 46. The other arm A has a flattened central portion 34 having an aperture 48 which fits over the pin 46 to pivotally interconnect the arms. As the arms are closed, the apertured flattened portion slides under the flanges to secure the arms together and when the arms are opened they may be separated. In an alternative construction, each bored head comprises a part-cylindrical portion secured to an arm and a complementary part-cylindrical portion mounted on a lever secured to the arm,the lever being spring-urged so that the head portions complete a cylinder. In use, the device may be withdrawn from a sutured body duct when the portions of each head are separated by moving the levers against the springs.

Title: Partial oxidation of hydrocarbons
IPC: C07C29/52
Filed: 1962-12-21
Abstract: <PICT:1013839/C2/1> In the partial oxidation of hydrocarbons in the liquid phase with a gas containing molecular oxygen fed separately into the reaction zone, a part of the hydrocarbon is introduced as a vapour into the reaction zone, whereby the reaction zone is heated and the provision of heat-exchanging means in the reaction zone is rendered unnecessary.  As shown, liquid hydrocarbon is treated with oxygen-containing gas in a reaction zone 10 to which vaporized hydrocarbon is supplied by a line 17 and an oxygencontaining gas by a line 15.  The vaporized hydrocarbon is produced in a heater 31 which is fed, through lines 20, 30, with unreacted hydrocarbon and water vapour produced in the reaction, the mixture of these products coming from the reaction zone 10 having been treated in a tower 12 with cold recycle mydrocarbon containing water.  This recycle mixture is obtained by passing the vapours from tower 12 through a condenser 13 and a separator 14. Fresh hydrocarbon may be supplied through line 33, and part of the vapours from the reaction zone may be returned thereto by line 20. The process may be applied to the partial oxidation of hydrocarbons of 2-10 carbon-atom, specified hydrocarbons being butane, pentane, methylbutane and cyclohexane.  An example is given of the partial oxidation of cyclohexane at about 330 DEG  F. and a pressure of 120 p.s.i.g. Specification 996,791 is referred to.

Filed: 1969-10-02
Abstract: 1280308 Filter networks INTERNATIONAL STANDARD ELECTRIC CORP 2 Oct 1969 [9 Oct 1968 10 Oct 1968] 48568/69 Heading H3U In a band pass filter comprising magnetically coupled coils the band widths to either side of the centre frequency may be varied independently of each other. The two peaks of the pass band situated to either side of the centre frequency correspond to lower and upper resonant frequencies and these frequencies are varied independently by varying independently the two different resultant magnetic fields produced at two different frequencies within the pass band when the respective fields of the coils either aid or oppose. As shown in Fig. 4, coils 1, 2 are magnetically coupled to each other and also to a closed conducting loop 3. An open loop 7 is provided in the loop 3 and constitutes a reactive impedance, this loop 7 being connected via a link 6 and a further open loop 5 to the opposite side of the loop 3. The loop 5 also constitutes a reactive impedance, the impedances of the loops 5, 7 being variable by movable ferrite cores (not shown) disposed therein. The lower resonant frequency corresponds to a condition in which substantially equal and opposited voltages are induced in the loop 3 at points A, B whereby negligible current flows through the loop and the lower resonant frequency may be varied by varying the impedance of loop 5, this effect being shown in Fig. 5a. At the higher resonant frequency the voltages at A, B are equal and of the same sign whereby negligible current flows through the link 6 and the higher resonant frequency may be varied by varying the impedance of loop 7, this effect being shown in Fig. 5b. In another embodiment, Figs. 6a, 7a, the variable reactive impedances are formed by a pair of ferrite bars 8, 9 positioned as shown and movable in the directions indicated by the arrows. In a further embodiment (Figs. 8a, 9a, not shown) the variable reactive impedances are replaced by a pair of variable resistors connected, respectively, in series with the loop 3 and in shunt across the points A, B.
