Abstract: 709,486. Printing-machines. MESSINGER, W. Nov. 6, 1951 [Nov, 6, 1950], No. 25968/51. Class 100 (2). [Also in Group VIII] In mechanism for driving a roll (e.g. the impression or other roll of a web printing machine) and for adjusting its position at right angles to its axis, an eccentric sleeve journalled in a support, and within which is mounted a bearing for a journal shaft on the roll, carries means for driving the roll and has means to turn the sleeve in its journal in the support. A journal shaft 21, Fig. 2, at each end of a roll 10 to be driven and adjusted, is carried in the eccentric bore of a sleeve 17 mounted by bearings 19 in a she!l 13 secured in a cylindrical part 15 of the machine side frame 11 by a cap 11a, Fig. 1; the shaft 21 has radial bearings 23 and may also have thrust bearings 25. At one end only, housings 38, 40, 41 extend from the sleeve 17 and support an electric motor, with its controls and suitable ventilating mechanism, whose armature shaft 43 drives the shaft 21 through two sets of epicyclic gears within the housing 38 ; these gears comprise a sun gear 47 on the shaft 43 which drives planet pinions 48 engaging a ring gear 51 fixed in the housing 38, the planet spider 49 having another sun gear 52 at its right hand end driving planet pinion 53 engaging a ring gear 54 also fixed in the housing 38, the second planet spider 55 being secured to the shaft 21. At both ends of the roll 10 the sleeve 17 has a bifurcated arm 29, Fig. 1, engaging a trunnion 31 on a rod 32 moved axially, e.g. through nut and screw gear, by a synchronous electric motor 33 ; the limits of this movement are determined by nuts, on the lower threaded part 34 of the rod 32, adjustable by manually-operated worm gear in housings 36, 37 on opposite sides of a fixed stop lug 35 ; thus the roll 10 after retraction may be rapidly and accurately returned to a pre-set operation position.

Title: Improvements in the isomerization of saturated aliphatic carboxylic acids
Inventor: ILLING GERHARD
IPC: C07C51/353
Filed: 1959-07-30
Abstract: Saturated aliphatic mono- and di-carboxylic acids having at least 4 carbon atoms are isomerised by heating them with carbon dioxide at temperatures between 150 DEG  and 300 DEG C., preferably under a pressure between 20 and 700 atmospheres, in the presence of (a) a metal carbonyl and (b) chlorine, bromine, iodine and/or one or more compounds of one or more of these halogens, and preferably (c) a compound of bismuth, antimony, titanium, boron, tin or iron as an activator and (d) water.  Suitable metal carbonyls are those of the 6th, 7th or 8th Group of the Periodic System, e.g. palladium, vanadium, chromium, iron, cobalt and nickel.  The carbonyls may be introduced as such or formed in situ from a hydroxide, oxide, carbonate, acetate, chloride, bromide or iodide. Suitable halogen compounds are the compounds of the halogens with each other, alkyl and aryl halides, halogen hydracids and their salts.  The activators may be the oxides, chlorides, bromides or iodides of the specified elements.  Suitable activators are bismuth oxide, antimony oxide, bismuth iodide, antimony bromide, hexachlorostannic (IV) acid, trichloro-tri-iodo-antimonic (III) acid, hexachlorotitanic (IV) acid, trichlorotriiodoferric (III) acid and the partial hydrolysis products of said halogen acids.  The activator may be supported on activated carbon, pumice or silica gel.  If the activator is a compound containing chlorine, bromine or iodine it is not necessary to employ additional halogen or halogen compound. In Examples, (1) adipic acid is isomerized yielding 2-methylglutaric acid and small amounts of 2,3-dimethylsuccinic acid, 2-methylbutyric acid and valeric acid; (2) suberic acid yields a -methylpumelic acid; (3) sebacic acid yields 2-methylazelaic acid; (4) n-valeric acid yields 2-methylbutyric acid; (5) 2-methylbutyric acid yields n-valeric acid.  The isomers are esterified with methanol and the mixture separated by distillation; (6) adipic acid is isomerized and the products are esterified with methanol in the presence of lead oxide and sulphuric acid to yield 2-methyl butyric acid methyl ester, methyl n-valerate, 2-methyl glutaric acid ester and dimethyl adipate and the products are separated by distillation.

Abstract: 644,989. Automatic gain control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 31, 1946, No. 26246. Convention date, Aug. 31, 1945. [Class 40 (v)] An A.G.C. circuit for receivers adapted for the reception of signals having recurrent maxima of fixed amplitude comprises a peak rectifier having a short discharge time constant followed by a limiter for reducing the effect of interference and a long time constant smoothing circuit from which the A.G.C. voltage is derived. The Figure shows a receiver for television signals in which the synchronizing pulses correspond with maximum carrier amplitude. The output of the I.F. amplifier 26 is applied to a diode 31 whose load circuit 38, 39 has a time constant equal to the interval between line pulses. The resulting rectified signals are applied to a diode 61 which is biassed to limit interference peaks to the normal peak signal amplitude and then through a long time constant smoothing network 71, 72 to a D.C. amplifier valve 44 which thus provides amplified A.G.C. signals at its anode. A negative H.T. source is applied to lead 46 and this provides a supply for amplifier 44 and also a delay voltage both for the limiter 61 and the amplifier 44 which may be adjusted by potentiometers 63 and 56, respectively. Potentiometer 56 may also be used as the manual gain control of the I.F. amplifier.

Title: Improvements in or relating to electromagnetically actuated contact apparatus for use with variable current
IPC: H02M1/26
Filed: 1947-09-30
Abstract: 648,396. Electromagnetic switches; sparking preventing. F.K.G. F. KESSELRING GERATEBAU AKT.-GES. Sept. 30, 1947, No. 26418. Convention date, Oct. 24, 1946. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 13, 1948]. [Class 38(v)] In an electromagnetic switch for A.C. or variable current, the resultant force acting on the contact member to cause the switching movement is advanced in phase relatively to the actuating current by imposing on the contact member two component forces produced by two circuits, one of which has an impedance adapted to displace it in phase relative to the other so that, for example; actuation may occur just before the current passes its zero point. Fig. 1 shows an interrupter or rectifier with a permanent magnet 1 forming the contact member and adapted to bridge the contacts 4, 5 on the poles 2, 3. With the contacts closed the current I passes from A to B through two parallel circuits, one including an impedance Z, and the other an impedance Z2 and an operating coil 7. From B the current passes through the operating coil 6 and the contact member I to C. The force on the armature due to the coil 6 is represented by the curve K, Fig. 2, and that due to the coil 7 is represented by the curve K2, relatively displaced in phase by suitable choice of impedances Z, Z2. The resultant curve Kr passes through the zero slightly before the curve K which may be regarded as substantially in phase with the current. Thus shortly before the current becomes zero, the resultant force Kr becomes negative and the contact element 1 is repelled to open the contacts and cause the insertion of an impedance Ze. The diminished force now follows the line Kr<SP>1</SP> and again becomes positive to close the contacts just before the current reaches zero. In a modification, Fig. 4, the movable contact 34 is carried by an armature 33 and is held " closed " by a spring 36 connected to a handle 45 when this is in its left-hand dotted position. To open the switch the handle is moved to the right and since this movement is slow compared with the period of the A.C., break will occur when the magnetic attraction of the armature is zero. In a further modification, Fig. 3 (not shown), the movable contact is carried by a movable coil which is acted upon by two phase-displaced fixed-coils.

Patent GB-1572369-A (GB)
Title: Electronic timepiece
IPC: G04G3/02
Filed: 1977-06-24
Abstract: An electronic timepiece uses a dynamic type shift register, as a time count circuit, which has a plurality of memory sections corresponding to an equal number of time count units and a cycle number memory section arranged such that it is preceded by said plurality of memory sections. An adder and shift memory unit are serially connected to the shift register to provide a shift circulation circuit and the shift circulation is effected by an oscillation signal from a reference oscillator. The adder adds [1] to the contents of the cycle number memory section for each data shift cycle of the shift register. Each time the count value of the cycle number memory section reaches a predetermined cycle number, the count value of a smallest time unit is counted one step. In this way, a carry is propagated to the subsequent large time unit memory sections according to the data shift circulation cycle of the shift register. A memory circuit is also provided which preliminarily stores a correction value corresponding to an error occuring between the oscillation frequency of the reference oscillator as generated per unit time and the standard oscillation frequency which drives the shift circulation circuit. Upon receipt of a correction timing signal the memory circuit has its correction value substracted at a rate of one circulation cycle per minute, thereby to correct such an error. The correction value indicates a total number of subtractive circulation cycle per hour.
