Abstract: 360,234. Binoculars. BARR& STROUD, Ltd. and FRENCH, J. W., Caxton Street, Anniesland, Glasgow. Dec. 6, 1930, No. 36815. [Class 97 (i).] In a binocular sighting-device comprising two parallel telescopes &c. with reference marks in the field of view and with variable interocular distance, in order to avoid alteration in the attitude of the reference marks when the interocular distance is changed, means are provided for imparting to one or both telescopes rotational movement equal and opposite to that ordinarily caused in the process of interocular adjustment. In the form shown, the frame carrying the telescope A is mounted on a pivot 7 about which it can be turned by a screw 16 to vary its distance from the fixed telescope B. To maintain unaltered the attitude of the graticule 3 in the telescope A, the telescope is mounted in bearings 5, 6 in its frame and is provided with a pin 8 pivoted to a link 9 pivoted at its lower end to a pin 10 carried by the fixed support 11. The points 13, 8, 10, 7 lie at the corners of a parallelogram so that as the interocular distance is adjusted the line 13, 8 remains in a fixed direction parallel to the line 7, 10. Other forms are described in which the rotational movement of the telescope is produced by spur &c. gearing, or by cams. Wear of the telescope A in its bearings may be reduced by a spring connected to the telescope and to a ring surrounding the pivot 7.

Abstract: 1,123,838. Electron multiplier circuits. GENERAL ELECTRIC CO. Ltd. 30 Aug., 1966 [27 Aug., 1965], No. 36908/65. Heading H3W. [Also in Divisions G1 and G3] The gain of an electron multiplier is varied by variation of the potentials of alternate dynodes, the potentials of the remaining dynodes being fixed. In an arrangement for stabilizing the working point of a photomultiplier, the voltage drop across a resistor 6 in the anode circuit is applied to the base of a transistor 7. The emitter potential is stabilized by Zener diode 9, which also supplies a potentiometer network of resistors 12 supplying fixed potentials to the 1st, 2nd, 3rd, 5th, 7th and 9th dynodes. A second potentiometer comprising resistors 13 supplies a potential dependent upon the anode potential of the tube to the 4th, 6th and 8th dynodes. The arrangement is stabilized against short-term variation of the anode current by means of a capacitor 8.

Filed: 1938-12-23
Abstract: 514,222. Rippling-machines. AUTOMATIC FLAX PRODUCTION UNITS. Dec. 23, 1938, No. 37520. Convention date, Dec. 31, 1937. [Class 120 (i)] [Also in Group I] A rippling-machine comprises one or a number of pairs of combs, each comb of one pair being arranged on one side of a conveyer device and the other comb on the other side of the conveyer device, each comb 1, 2, Figs. 1 and 2, being carried by a comb-holder and the combholders 5, 6 of a pair being pivoted together at 7 in the upper part of the machine being ..actuated between the comb and the pivot 7 by a member, e.g., disc 10 or 11, having a continuous motion of rotation so that each comb in addition to a downward movement is given a reciprocatory lateral movement and the trajectory of the combs is substantially elliptical. The comb-holders 5, 6 are pivotally mounted on crank-pins 8, 9 formed on the toothed discs 10, 11 which are driven from a shaft 13. The flax stalks are fed into the machine on a table 48<2> and are carried forward by a conveyer device comprising an endless belt 24 engaging a disc 15 and raving co-operating rollers 19, the cleaned stalks being discharged on to the table 41 by the toothed discs and fed therealong by the toothed discs which rotate at increasing speeds and so produce a thin uniform layer. Rollers may be substituted for the toothed discs. The comb teeth are cleaned by brushes 48'. In a modification two combs are provided on each side of a conveyer comprising endless belts the comb-actuating toothed discs being provided with crank-shafts and the combholders being pivoted together at two points in the upper part of the machine. The arrangement is such that when a comb at each side of the conveyer is near the conveyer the other pair of combs are remote therefrom. The teeth of the pair of combs nearer the conveyer are closely spaced for removing the seed pods while the teeth of the other combs are more widely spaced for parallelising the flax stalks.

Title: A device for feeding package wrappers
IPC: B65C1/00
Filed: 1968-02-15
Abstract: 1,211,377. Supplying wrappers; feeding sheets. E. SERAGNOLI, A. SERAGNOLI and M. C. SERAGNOLI, [trading as G.D. SOC. IN ACCOMANDITA SEMPLICE DI ENZO SERAGNOLI E ARIOSTO SERAGNOLI]. 15 Feb., 1968 [20 April, 1967], No. 37543/67. Headings B8C and B8R. Apparatus for distributing and gluing wrappers, particularly in a cigarette-packaging machine, comprises a hopper, a member for removing wrappers individually from the hopper by means of a suction circuit, a roller immersed in a glue tank and capable of transferring glue to a member which then applies glue to a wrapper, and means for automatically causing a break in the supply of wrappers and correspondingly separating the roller from the glue-applying member when no article to be wrapped will be present at a subsequent station. Transport of wrappers.-A pile of wrappers (not shown) is positioned on a movable base 27 in hopper 11, Fig. 3, which is adjustable in size and which is provided with a microswitch 22, 22a which operates a signal when the pile approaches exhaustion. At the beginning of a cycle, a suction gripper sector wheel 37 is positioned at the left end of a slot 24, as shown in dash-dot lines in Fig. 3. In this position, the open end 39b of a suction passage in spoke 39 in wheel 37 is in contact with the bottom of the pile of wrappers. Translation and anti-clockwise rotation of wheel 37 along slot 24 is now begun, and simultaneously a cam 51 is rotated on a shaft 10 causing a valve sleeve 74 to slide in its seat 75, thus allowing communication between pipes 70 and 71, and transmitting suction to spoke 39 by way of pipes 68, 69, 70, 71 and 73. The lowest wrapper is thus held by suction against the surface 38 of wheel 37 and is moved to the right until the further end of slot 24 is approached. At this stage, the cam 51 again operates valve 74 and cuts off the connection to the suction source via pipe 68. The wrapper is now lying on the surface of a roller 50, which rotates clockwise, passing the wrapper beneath further smaller rollers and finally delivering the wrapper into a slit between two plate guides (129, 130), Fig. 4 (not shown). The wrapper is made to descend this slit. by driven rollers. Gluing wrappers.-A pick-up roller (105), Fig. 4 (not shown), dips into a glue tank (106) and transfers glue on to rotating sectors, orientated so that they come into contact with predetermined areas of each wrapper as it passes over a revolving counter-roller. The glued wrapper now descends between guides on its way to a wrapping station (not shown). Automatic control.-If a gap occurs in a succession of articles to be packaged, a sensing and memorizing unit (not detailed or shown) sends a signal at the appropriate time to two electromagnets. Energizing a first magnet 80 causes a tooth 81 to engage a notch 82 in sleeve 74, thus maintaining the suction valve closed so that no wrapper is removed from the hopper 11. Further, glue is not applied to the rotating sectors since a second magnet causes the glue tank (106) and roller (105) to move away.

Title: A process for the preparation of aldehydes and/or alcohols
IPC: C07C45/50
Filed: 1962-10-04
Abstract: Aldehydes and/or alcohols are prepared by reacting a compound having an olefinic linkage with carbon monoxide and hydrogen in the presence of a complex of a transition metal having an atomic number from 23 to 32, 40 to 51, or 57 to 84 with at least one molecule containing trivalent phosphorus, arsenic or antimony and separating the resultant mixture while maintaining a protective medium of at least one olefine.  The olefine used as the protective medium is preferably a C2-C8 alkene. The preferred catalysts are those containing cobalt as the transition metal and a phosphine such as tri-n-butyl-phosphine or triphenylphosphine as the molecule of the trivalent element. Preferably the feed comprising the olefinic compound to be hydroformulated, carbon monoxide and hydrogen is mixed with recycle and/or fresh catalyst and reacted, e.g. at 300-700 p.s.i.g. and 150-180 DEG  C.  The product is separated from the catalyst while maintaining a substantial concentration of protective olefine.  It is convenient that the protective olefine should be the same as the one being hydroformylated.
