Abstract: 1284106 Community aerial system PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 NON 1969 [15 Nov 1968] 55406/69 Addition to 1237089 Heading H4R In a television community aerial system, of the type of parent Specification in which two way repeater distribution amplifiers are provided each including a normal amplifier and a spare amplifier with automatic switching of the spare amplifier into service on detection of a fault in the normal amplifier, whose performance is monitored by a pilot signal; the pilot signal is locally generated at the repeater and fed into the repeater amplifier input to prevent amplifier change over due to attenuation of the pilot signal over the transmission system, or having to transmit the pilot at high signal strength, likely to cause inter-modulation, in order to prevent such change over. Fig. 2 shows the preferred embodiment of the repeater amplifier including parallel amplifier paths, 1 and 4. A pilot signal from a pilot oscillator, Fig. 3 (not shown), is fed to the common input and the output from the normally operational amplifier 1, is fed to a detector 107 and switch over circuit 3. Failure of the pilot oscillator causes operation of switch 3 to cut the power supply to amplifier 1 and activate amplifier 4. Once the change over is made the switch stays in the changed over condition until the power supply to the switch is interrupted.

The radiation sensitive metal compound may be silver halide, silver oxalate, palladium oxalate (Ex. 1), titanium dioxide (Ex. 2), ferric potassium oxalate trihydrate (Ex. 3) or zinc oxide (Ex. 4-6). Physical development may form a nickel (Ex. 1) or silver image (Ex. 2-6). The colour coupler may be in the material (Ex. 1-3) or in the amplifier solution (Ex. 4-6). The colour developing agent may be an aromatic primary amino compound. The cobalt ion complex may be cobaltic hexammine chloride. The couplers may form diffusible or non-diffusible dyes, and in the former case the resultant dye may be transferred to an image-receiving sheet.

Abstract: 1,215,347. Viscometer. FALLING NUMBER A.B. Dec.2, 1968, No.57079/68. Heading G1S. A tank 2 contains liquid heated to 100‹ C. and is provided with a level regulator 20, a vapour cooler 21, and a viscometer tube 3 immersed in the bath and containing a stirrer viscometer 4 which is reciprocated vertically by a motor rotated grooved drum 7 engaging a projection 8a. The tube 3 is secured in position by a slide 9, and a latch 18 operated by a release magnet 15 retains the head 4b of the stirrer inter-connected with the lifting arm 8. In operation the tube 3 is filled with sample material, e.g. flour, and the stirrer 4 reciprocated vertically for 60 seconds, the stirring is then discontinued when the stirrer is at the top. The latch 18 is now released so that the stirrer 4, now serving as a gravity body, falls freely a predetermined distance in the tube 3 until a pulse emitter 19 strikes and closes a contact 17. This contact stops a counting mechanism 13, and the period of time on the counter is used to indicate the viscosity. In Figs. 3-5 (not shown) a driven gear wheel (8) has a crank-pin (22) which engages in a notch (23a) in a T-shaped member (23) supporting and reciprocating the stirrer (not shown) by means of jaws (50). The jaws are opened to release the stirrer for its gravity fall when a tongue (54) is lowered into the path of a cam (61) to operate a switch (55) and automatically stop the driving motor, a rod (59) at this time engaging an abutment (60) and being moved down to depress an element (58) and release the jaws.

Abstract: 1275447 Exposure control circuits CANON K K 24 Nov 1969 57396/69 Heading G2A An exposure control circuit automatically switches a fixed resistor R in place of a photoconductive element Rc forming part of RC shutter timing circuit when the brightness of an object to be photographed is lower than a pre-set value. Upon depression of shutter release a divided voltage is produced at point A determined by film speed resistor Rv and photo-conductor Rc, and when this voltage is lower than a pre-set value warning circuit W is operated to energize a warning lamp L and an electromagnet M 1 . A switch S 2  in a flash circuit is closed, a switch S 3  is closed to energize an electromagnet M 2  which allows diaphragm blades to run down an aperture determined by a profiled cam on a focusing ring when switch S 5  is closed by further movement of the release and switch S 4  is changed over to position b to bring resistor R into the RC timing circuit. Finally switch S 6  is closed to commence shutter operation. The shutter blades may also be used as the diaphragm blades. During automatic timing the film speed is set by a diaphragm in front of the photo-conductor.

A vibrating screen 9 for particulate materials is driven by two unbalanced means 4, 8 which are independently rotated about axes 5, 7, extending transversely of the direction of conveyance of the materials on the screen, at different speeds related by a ratio of two whole or substantially whole numbers chosen from among the numbers 1 to 10 inclusive. The term "substantially whole number" is defined as a number which differs slightly from an integral value. The screen 9 is mounted in a box I supported at an angle of 20 to 40‹ on a base 3 by springs 2. Shafts 5, 7 carry out-of-balance sector-shaped weights 4, 8 and are driven by motors (not shown) mounted outside or inside the screen box. The shafts may rotate in the same or in opposite directions. In a modification, the unbalance means are connected through gearing, the reduction ratio of which corresponds to the speed ratio. Diagrams of various compound oscillations are given.
