Abstract: 902,442. Crayons; marking animals. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. July 15, 1960, No. 24781/60. Classes 73 and 146 (3). A crayon composition for use in marking sheep comprises a wax, a solid saturated fatty acid, a liquid unsaturated fatty acid, a filler and a pigment. The composition may be 14 to 25% (by weight) wax, 14 to 25% solid saturated fatty acid having a melting-point between 52‹ C. and 58‹ C., 10 to 35% liquid unsaturated fatty acid having a melting-point of less than 2‹ C., 30 to 50% asbestos powder, 4 to 7% insoluble pigment and up to 2% asbestos fibre. Example T. Beeswax 18%; stearic acid 18%; oleic acid 12%; asbestos powder 47%; asbestos fibre 1%; pigment 4%. The pigment may be blue, scarlet, green or yellow. The composition is made up into a crayon for attachment to a harness worn by a ram, the crayon serving to mark the ewes with which the ram has mated. The crayon is mounted on a metal plate for attachment to the harness by the following method: a piece of fibrous cloth which has been soaked in warm crayon mix is wired to the metal plate while still warm. The metal plate is then fitted in a mould and a quantity of warmed crayon mix is poured on and around the treated cloth and allowed to solidify.

Title: Power supply apparatus
IPC: G05F1/613
Filed: 1961-07-11
Abstract: 987,676. Automatic voltage regulators. BASIC PRODUCTS CORPORATION. July 11,1961 [July 11, 1960], No. 25040/61. Heading G3R. [Also in Divisions H1 and H2] The direct voltage at output terminals supplying a variable load is maintained constant by automatically varying the resistance value of a short circuit connected across the output terminals. As shown, a voltage source depicted as a battery 10 and a series resistance R s  supplies a variable load Rd connected to output terminals 11, 12. Variations in the value of R d  cause corresponding variations in load current, and hence variations in the voltage drop across R s  and in the output voltage at terminals 11, 12. These output voltage variations are sensed by a circuit 13 which acts to vary, in a corrective manner, the resistance of a resistor R c  connected in shunt with the load Rd, the arrangement being such that the parallel combination of resistors Rd and Rc is a constant resistance. The total current is thus maintained constant, and hence the voltage at terminals 11 and 12 is also maintained constant. In a particular embodiment (Fig. 2, not shown), the voltage source comprises a transformer which is similar to that disclosed in Specification 798,764 but modified to,have a drooping volt-ampere output characteristic and which is connected to the D.C. output terminals over a rectifying and filtering network, the correcting resistor Rc includes at least one transistor the conductance of which is varied in dependence upon output voltage variations, and the voltage sensing circuit 13 includes a reference Zener diode and further transistors, including a positive feedback path, for deriving and amplifying the control signal which is applied to the resistor Rc.

The members 1, 2 each carry a slide 8, adjustable transversely by a screw 10 on which is mounted a bracket 12 vertically adjustable by a rack 16 and pinion 14. The mirror B<2> is similarly adjustable transversely and vertically. Fig. 9 shows in plan an illuminating system in which a drum A, of smaller size, contains a prism P to reflect laterally to the lens C the beam passing through the film from a lamp B, condenser B<1>, and reflector B<2>, outside the drum. The relative positions of the lens C and the parts B, B', B<2> may be reversed. The drum may have one or two rings of picture apertures a and sprocket teeth a<1> may be arranged at the middle of the bars between the apertures or at the lateral margins of the apertures. As shown in Fig. 12, the drum comprises spaced rings A<2> mounted separately on annular bearings a<2>, a<3> and rotated by a toothed roller a<4> or by worms. In a further modification a single toothed ring driven by a maltese cross moves the film round a stationary drum or over a ring of rollers. The Provisional Specification describes a modified form of maltese-cross mechanism in which the slots of the cross are formed in one wheel and the locking portions on a parallel wheel secured to the same spindle.

Abstract: 696,281. Correspondence control. POSTMASTERGENERAL. Oct. 19, 1949 [Sept. 29, 1948], No. 25392/48. Class 40 (i) [Also in Groups XXXVI and XL(c)] A directional radio aerial system comprising an array of vertical aerials arranged in rows having a common point of intersection (see Group XL(c)) is adapted to have directional properties controlled electrically in azimuth and elevation by rotation of the arms of capacitive commutators connected to delay networks, one such commutator being provided for each row of aerials. It is shown that if # is the angle between adjacent rows of aerials and it is desired to utilize a direction having azimuth α and elevation # then for the nth row of aerials the angle γn of the commutator arm from its central position is given by:-  γ n  = #/2 cos # cos (a - #). A motor SMn is arranged to rotate the shaft Sn through the required angle yn by means of cosine potentiometers as indicated in Fig. 2. A source of e.m.f. of magnitude E is applied to cosine potentiometer CPo which is rotated through the angle of elevation # and gives an output E cos #. This is fed to cosine potentiometers in parallel each feeding a motor for one row of aerials, and rotated through the angle of azimuth a by a common shaft CPS, the system for the nth row only being shown in Fig. 2. The contact arm of each of the parallel-connected potentiometers is permanently displaced by angle # relative to its neighbours so that the potentiometer CPn is actually set to (a - n #) and gives an output E cos # cos (α - n #). This is fed in series opposition with the output E<SP>1</SP>n of a linear potentiometer LPn to the motor SMn which rotates the potentiometer LPn until the two outputs balance. Since potentiometer LPn is arranged so that E<SP>1</SP>n = γn/#/2 E. the required condition that γn = #/2 cos # cos (α - n #) is, obtained.

Abstract: 586,907. Automatic control systems. SCHWARZ, B., and MOSSAY, P. A. H. Dec. 19, 1944, No. 25471. [Class 38 (iv)] [Also in Groups XXXVII and XXXVIII] Speed.-In a control system for a plurality of electric motors, (see Group XXXVII), each motor has a spaced regulator operated by a pilot motor which is controlled by the difference between a reference voltage adjusted by a common master shaft and a voltage dependent on the setting of the speed regulator for, or the adjusted speed of, the individual motor under control. Each working-motor M is coupled to a tachometer generator TD, and the armature of each direct-current pilot motor PM is connected in a bridge circuit between the movable contact of a potentiometer P1, which is adjusted by a common master shaft MS and one of the brushes of the tachometer generator. The field windings of the pilot motors and the tachometer generators are supplied from a constant direct-current source, variable regulating resistances being included in the tachometer generator field circuits. Any deviation between the voltage set by the potentiometer PI and that of the tachometer generator will cause the pilot motor to rotate in an appropriate direction to adjust the speed regulator of the motor M and correct such deviation.
