Abstract: 777,321. Mixing fluids in flow. COUGHTRIE, D. Aug. 7, 1953 [May 7, 1952], No. 11527/52. Class 86 [Also in Group XXVIII] Apparatus for mixing two or more fluids, especially liquids which may in some cases contain dispersed solids or gases comprises a cylinder A, an inlet pipe B at one end for a first fluid, an outlet pipe C at the other end for the mixed fluids a lateral inlet port A2 for a second fluid in the side wall of the cylinder intermediate its ends, an annular piston D in said cylinder, a hollow piston rod D1 carrying the piston and guided in the outlet pipe C and providing communication from the inlet end of the cylinder to the outlet pipe, a spring E urging the piston D towards the inlet end of the cylinder and a passage in said piston opening into the interior of the piston rod and comprised by one or more ducts D3 and a circumferential groove D2 adapted to register with the lateral inlet port A2 to an extent determined by the position into which the piston is moved by the thrust of the first liquid against the piston acting in opposition to the spring E. The substances introduced through the port A2 may be supplied under pressure in which case the piston is arranged so that an increase in the pressure of the supply of first liquid causes an increase inthe area of port A2 in register with the groove D2, thereby increasing the flow of second fluid as the supply of the first fluid increases. -In order to vary the proportions of the mixture the pressure on the spring E is varied by screwing the nozzle C into or out of the cylinder A. Further variation in the proportions may be effected by providing interchangeable springs E of different strengths or by inserting washers or adaptors between the spring E and nozzle C. In an alternative arrangement the ducts D3 are inclined towards the discharge end of the cylinder A so that the introduction of second fluid is effected by induction. The internal diameter of the rod D1 may be increased down to the discharge end to increase the induction effect. To maintain constant proportion between the first fluid and an induced second fluid the groove D2 is arranged so that it first moves rapidly down into register with the port A2 and then, upon any increase in pressure it moves further down thus partly closing the port A2. To mix a plurality of additional fluids a plurality of inlet ports A2 may be provided and the piston D is provided with circumferentially separated ports in place of the groove D2 each connected by one or more ducts with the interior of the rod D1, the rod D1 then being of square section to prevent rotation of the piston. For regulation of the fluids adjustable valves may be provided on each inlet connection A1 leading to the ports A2, and the ports A2 may be formed as perforated screwed plugs associated with non return valves.

In a television system, aperture correction in a direction transverse the scanning lines is effected by (1) subjecting the scanning spot to a transverse wobble deflection under the control of a sinusoidal oscillator 17 operating at twice the system cut-off frequency, 6 Mc./s. in the example described, so as to cause the exploration of the adjacent line areas on either side; (2) extracting the video information respecting said adjacent areas, which occurs as modulation of twice the wobble frequency in the band 9- 15 Mc/s., by means of band-pass filter 19, demodulator 20 and low-pass filter 23; and (3) subtracting said extracted information in mixer 16 from the video information respecting the main scanning lines which is derived via low-pass filter 13. The main video signal via filter 13 is also subjected to aperture correction for the line direction in stage 14 and fed through a delay circuit 15 to equalize the delay in channel 19, 20, 23. A 12 Mc/s. signal to operate demodulator 20 is obtained from oscillator 17 via phase adjuster 21 and frequency doubler 22. Filters 13 and 23 may be replaced by a single filter following mixer 16. It is stated that the effect of the invention is to provide a video signal corresponding to that due to normal scanning together with a negative signal component proportional to the second differential with respect to distance transverse to the scanning lines of the brightness of the image.

In a wedge-type brake-applying mechanism, particularly one forming part of an internal shoe drum brake, wedge surfaces 18 of a wedge 16 act via rollers 30 on inclined surfaces 28 of tappets 20, and each tappet is composed of two separate parts 22, 24 normally maintained in contact by the shoe return springs 40 but separable by a compression spring 26, arranged in mating recesses of the two parts, should a sudden jolt, e.g. caused by a wheel of a vehicle to which the brake is fitted dropping into a pothole in the road surface, overcome the tension in the springs 40 and allow a shoe to move towards the drum when the wedge is in the brakes-off position. By this arrangement, and by arranging that each tappet part 22 is substantially smaller and lighter than the corresponding tappet part 24 the surfaces 28 are maintained in contact with the rollers 30 which are thus prevented from falling down the wedge. Movement of the rollers up the wedge is restrained by a U-shaped stirrup 50 the limbs of which bear on axial extensions of the rollers which are of reduced diameter, the stirrup being urged downwardly by a spring 48. The wedge is floating and has inclined end faces co-operating with inclined seats 32 for centring it in the brakes-off position. The spring 48 is seated in a removable cover plate 46 secured to the housing 10. The brake shoes have twin webs which at one end slidably engage seats formed on the housing of the mechanism, their other ends slidably engaging a suitable abutment secured to an anchor plate and incorporating wearadjustment means.
