Abstract: 1,163,017. Gyroscopic apparatus. BELL & HOWELL CO. Sept. 28, 1966 [Oct. 24, 1965], No. 43353/66. Heading G1C. [Also in Division G2] The line of sight of optical instruments such as cameras or binoculars is stabilized by a gyroscopic rotor against vibrations of high frequency and low amplitude, but in order that the line of sight should follow low frequency high amplitude movement, such as in panning a cine camera the rotor is precessed into alignment with the casing with a rate of precession dependent upon the operating conditions of the instrument. As shown, Fig. 2, applied to a cine camera the line of sight is stabilized by a variable wedge formed by the lens 26 fixed to the housing and a lens 30 fixed to a spherical rotor 32 which is rotated by a rotor drive member 68 driven through shaft 84. A series of friction members 90 bear against the spherical surface of the rotor 32 so that when the camera axis moves, such as from 36 to 36<SP>1</SP> the rotor 32 is precessed into alignment with the new position 36<SP>1</SP> of the camera axis, the rate of precession being controlled by the current supplied to coils 120 acting upon the friction members 90. A pair of rate gyros Figs.6, 9 (not shown) having perpendicular input axes may control the current to the coils 120 or sensing coils may be provided to sense changes of relative motion between the rotor and its housing. In a modification, Fig. 13, precession is controlled by supplying the current to a coil 220 which induces eddy currents in an insert 224 on the rotor. As applied to a zoom binocular the rate of precession may be made dependant upon the magnification of the binocular.

Abstract: 441,370. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. June 4, 1935, No. 16239. Convention date, June 4, 1934. [Class 40 (v)] In a cross-coil visual indicator for use when steering on an overlapping-beam system, the mean direct-current component of the co-operating signals, Figs. 2 and 3, is filtered out so that the final form of the impulses applied to the indicator is as shown in the bottom-line of those Figures. In this form the impulses are applied to the crossed coils S1, S2, Fig. 1, through reversed rectifiers G1, G2. The object is to prevent the growing strength of the impulses, as the aeroplane approaches the transmitting beacon, from affecting the accuracy of the readings. The system is applicable to modulated signals or to unmodulated signals received by a local heterodyne. The output from the last valve Nf, Fig. 1, of the receiver is rectified at GO and applied across a resistance R1 and condenser C1 to produce the voltageform UR1, Figs. 2 and 3. The direct-current component is then filtered out by a condenser C2, and applied across a resistance R2 to give the voltage-form UR2, which is applied to the crossed coils S1, S2 through reversed rectifiers G1, G2. To produce a dead-beat swing of the pointer P, each coil is shunted by reversed rectifiers G3, G4 and variable resistances r3, r4 ; also the gap of the magnet M is of elliptical cross-section.

Abstract: 1367117 Automatic phase control RCA CORPORATION 22 Sept 1971 [30 Sept 1970] 44154/71 Heading H3A In a retroactive synchronizing system, e.g. for the vertical time base of a colour TV receiver, the phase error control signal is applied to the controlled signal generator via means which detects when the reference synchronizing signals exceed a predetermined pulsewidth. Signals from a clock generator 55 (Fig. 1, not shown) are fed to a divider 60 which divides them down to the vertical sync rate and applies the divided output to a gate 216C where it is compared with the external sync signal from stage 26 (Fig. 1, not shown). If the two signals are in synchronism the output from 216C inhibits bi-stable 218 and pulse width detector 80 and the divider is reset via R1. If the two signals are not synchronized the detector 80 is enabled by a signal on gate 219. When the next external sync pulse arrives the gate 219 opens to pass clock pulses to counters 221 ... 224 which provide a pulse on R2 after a count of thirteen to reset divider 60. Thus a reset pulse is only provided on R2 if the external sync pulse is sufficiently long for the counters to reach thirteen.

Title: Mercury-containing organosilicon compounds and compositions
Inventor: MASON ERNEST ARTHUR
IPC: C08G77/398
Filed: 1961-12-11
Abstract: Mercury-containing siloxanes are made by heating an organopolysiloxane containing at least one phenyl group attached to Si either directly or through an alkylene group, with a mercuric salt.  The siloxane may be an oil, resin or elastomer, but is preferably an oil.  Mercuric salts specified are the acetate, benzoate, nitrate and perchlorate.  If desired the salt may be formed in situ from the oxide and the appropriate acid or acid anhydride. The reaction is effected by heating at 100 DEG  to 200 DEG C. in the absence or presence of a liquid which is a solvent for one or both of the reactants, e.g. methanol, ethanol, nitrobenzene, dichlorobenzene, water and mixtures of these with acetic acid or anhydride.  In a typical example (1), an end-blocked siloxane oil containing dimethyl- and diphenyl-siloxane units was mixed with mercuric acetate, acetic acid and nitrobenzene, and the mixture was heated at 115 DEG  to 120 DEG C. for 12 hours to yield, after purification, a pale yellow oil containing 0.15% (by wt.) of Hg.  The solid product of Example 6 was in a siloxane oil containing dimethyl- and methyl(phenyl-ethyl)-siloxane units to give a solution having a mercury content of 0.7%.ALSO:Bactericides comprising mercury-containing organopolysiloxanes are made by reacting an organopolysiloxane containing at least one phenyl group attached to silicon either directly or through an alkylene group, with a mercuric salt (see Division C3).  In Examples (1) the oily reaction product of a trimethylsilyl end-stopped methylphenylpolysiloxane and mercuric acetate possessed good spermicidal properties; and (6) a solution in a silicone oil of the reaction product of tetra-(b -phenylethyl)-tetramethylcyclotetrasiloxane with mercuric acetate inhibited the growth of Staphylococcus aureus and Salmonella dublin.

Abstract: 1,210,491. Feeding sheets. MARDON, SON & HALL Ltd. 9 Jan., 1968 [12 Oct., 1966], No. 44415/66. Heading B8R. Sheets are removed from a stack supported on edge and deposited on a substantially horizontal conveyer by grasping means (e.g. suction pads) pivotally attached to pivoted arms, the arms being adapted to swing between a first position in which the grasping means may grasp a leading sheet and a second position in which the grasping means holds the sheet in a substantially horizontal plane for release on to the conveyer. The grasping means are arranged to pivot relative to the arms during movement of the latter such that the sheet is moved in an arcuate path transversely of and away from the stack. The pivotal movement of the grasping means is completed in less than the full swing of the arms. Blanks 11 are individually withdrawn from stack 10 and fed to a conveyer 12 by suction cups 28, 30 pivotally mounted on bar 27 which is in turn supported between pivoting arms 25, 26. As arms 25, 26 reciprocate through an 80-degree angle cam follower 43 rolls on cam surface 44 thus reciprocating rod 41 and through linkage 45 oscillating shaft 27 through. about 60 degrees. Cups 28, 30 therefore pivot from position 28 to position 28b where the vacuum is released, thus transporting a blank first from behind retaining member 15 and then away from and transversely of the stack (and from behind member 16) to be deposited on conveyer 12. In an alternative embodiment (Figs. 3 and 4, not shown) two pivoted arms (125, 126) each carry a suction cup (128, 130) mounted in a holder (170). Oscillation of these arms through 80 degrees causes the cups to pivot through more than 110 degrees to withdraw the blank as before.
