Title: Improvements in and relating to colour television apparatus
IPC: H04N9/24
Filed: 1961-05-09
Abstract: 968,702. Colour television; cathode-ray tube circuits. PHILCO CORPORATION. May 9, 1961 [May 9, 1960], No. 16825/61. Headings H4F and H4T. In a beam-indexing cathode-ray tube 20, compensation for the different phosphor efficiencies (particularly that of the less efficient red phosphor with respect to the blue and green phosphors) is effected by deriving a sinusoidal signal at colour triplet frequency from the indexing signal circuit 21-24 and after appropriate adjustment of phase in control 32 adding it in stage 27 to the tube modulation signal (luminance plus chrominance) so that the beam intensity is additionally varied during the scanning of each triplet to bring about colour balance. Preferably the signal is applied through a modulator 32 controlled by the luminance signal, which is adjusted in amplitude by a gain-control stage 34, so as to achieve correct compensation at all levels of brightness.

Title: Improvements in or relating to fluid pressure operated apparatus
IPC: F15B11/02
Filed: 1943-10-18
Abstract: 569,312. Hydraulic accumulators. SMITH'S JACKING SYSTEMS, Ltd., SESSIONS, D. W., and PICKARD, S. J. Oct. 18, 1943, No. 17074. [Class 69 (ii)] [Also in Group XXVIII] A pump byepass valve 25 is closed against discharge pressure by a spring 28 held compressed by a snap-action device 31 which is actuated to release the spring pressure when an operation effected by the pump is completed. The pump may supply a hydraulic jack 17 which, on completion of its movement operates a lever 41 to trip the snap device. The latter may comprise a pivoted block having surfaces 33, 34 at different radii from the pivot and so arranged that initial rotation of the block compresses the spring until the point 35 is below the pivot, whereupon the spring pressure completes rotation of the block until the surface 34 of lesser radius contacts the spring abutment 29. In this position, the spring is uncompressed and the byepass valve opens under pump pressure. The block 31 may be replaced by a toggle device. In an alternative method of operation, the pump pressure operates a ram 45 against the action of a spring 46. The block 31 is thus tripped by the ram 45 when the discharge pressure exceeds the tension of spring 46. The pump may supply an accumulator in place of the jack 17.

Title: A method for the line-by-line production of cylindrical half-tone screen printing formes
Inventor: VOS FERDINAND ALLARD DE
IPC: B41C1/04
Filed: 1969-04-01
Abstract: 1278123 Copying by scanning WERKSPOOR-AMSTERDAM NV 1 April 1969 [2 April 1968] 17089/69 Heading H4F In a system wherein a single master pattern 2 on a rotating cylinder 1 is repeatedly scanned by a photo-electric element 3 moving parallel to the cylinder axis, and a half-tone screen printing forme on a cylinder 6 is synchronously scanned under an engraving element 5, controlled by signals from element 3, to provide a repeating pattern, there is a delay between the time at which a signal is delivered to start scanning and engraving and the time at which these actually commence, so that part of the line being scanned e.g. the first line 7 of master 2, is not engraved e.g. the first line 8 of the second pattern on cylinder 6. Such a line is therefore moved over its entire length twice under the element 5, on one scan being in operational contact with the element over at least a first part of its length, and on the other scan being in operational contact with the element over a final part of its length, the first and final parts being complementary or overlapping parts of the line. In a preferred embodiment, the first and last lines of master pattern 2 are identical. At the end of the scan, engraving only the first part of the last line, (the intended first line 8 of the next pattern) a control signal renders element 5 inoperative and element 3 returns to the first line 7 of the master. At the commencement of the next scan, element 5 returns to the part-engraved line 8 to complete the engraving thereof. Any overlap of scans is said to be unimportant since the scanning action is identical in both cases.

Filed: 1946-06-11
Abstract: 612,940. Winches. NORBURY, E. June 11, 1946, No. 17360. [Class 78(v)] A winch comprises a driving shaft 12, Fig. 1, a drum 13 journalled on the shaft and having an axiallyextending flange 15 on one side, a fixed plate 16 over the flange opening, a sun-gear 22 fixed on the shaft and connected with an internally-toothed annulus 23 on the flange by a planetgear 19 supported by the carrier 18 journalled on the shaft, and a doubleacting brake shoe 27, 26 which is supported by the plate and selectively movable to brake the carrier or the flange. In the embodiment, the winch is controlled by latch-released lever 31, Fig. 2, which is connected by toggle levers 29, 30 to brake shoes 26, 27, which are pivoted at 28, to stationary plate 16; and is also controlled by pawl 34 pivoted to plate 16 and held by spring 35 against ratchet teeth 33 on drum flange 15. In the position of Fig. 2, the brakes hold planet carrier 19 and the motor drives the drum to wind in the rope. When the lever 31 is moved to the right, the brakes are applied to the flange, and abutment 38 on an extension of lever 31 catches arm 40 fixed to the pawl and moves the latter away from the ratchet so as to be held by leaf spring 41. When the lever 31 is moved back to the left to an intermediate position, the pawl is fixed and the brake is unapplied so that the rope can pay out freely. When moved fully to the left, the brake brakes the carrier and abutment 43 on the extension of lever 31 knocks arm 40 and causes the pawl to contact the ratchet teeth. Fig. 4. To prevent the cable weight unwinding the cable from the drum, an arm 48 is pivoted to the stationary plate 16 at 46 and applies a brake 45 to the drum periphery when the cable, which passes through loop 49 of the arm 48, slackens. The winch may be mounted on a tractor and be driven by the power take-off shaft so as to actuate a crane also mounted thereon. Specification 613,227 is referred to.

The pistons 26, 27 are connected to telescoping piston rods 29, 32, which slide one within the other and carry cam-followers 71, 74, co-operating with a cam 72 to rotate the drive shaft 59. The combustible mixture is fed through manifolds 18, 24, and reed-type inlet valves 15 into compression chambers 46, 45, on the rear sides of the pistons, the compressed charge being forced into the combustion chamber 47 between the pistons through automatically opening valves 41 in the pistons when the latter, at the end of their outstroke, uncover exhaust ports 35. On the succeeding compression stroke the charge is ignited by a spark plug 55 carried by the piston rod 29 which has orifices 56 connecting the space around the electrodes to the combustion space. The current to the plug 55 is carried by a spring 52 enclosed in an insulator 53. The cam 72 is carried by a cam block 67 mounted in bearings 61, 62, and integral with the drive shaft 59 carrying flywheel 79. Rotation of the inner piston rod 29 relative to the outer rod 32 is prevented by slides 89, Fig. 10, engaging slots 90 in the outer rod 32 through bearing rollers 91 and rotation of the outer rod 32 is prevented by similar sliders 84 and rollers 86 engaging guide slots in a stationary sleeve 21. Lubricating oil supplied at 93 flows through pipes 99, 101, to passage 103, Fig. 6, in the inner piston rod 29 and to grooves 110, 111 in the outer surfaces of the piston rods. From passage 103 the oil flows into chamber 107 in the upper piston 26 to cool it and then flows to return passage 107<SP>1</SP> in the piston rod 29. The grooves 111 deliver oil to chamber 115 to cool the lower piston and thence through passage 117 to return passage 107<SP>1</SP> which delivers oil on to the rollers 71, 74, and into casing 65 from which it returns to the sump. An accessory drive pulley 83 is driven off the drive shaft 59 through gearing 82.

Filed: 1943-10-25
Abstract: 568,477. Twisting. BLACKBURN AIRCRAFT, Ltd., and GREENWOOD, G. Oct. 25, 1943, No. 17525. [Class 83 (iv)] Straight or bent lengths of tubes or bars of rectangular or similar cross-section are twisted by a tool comprising a part having a substantial engagement with the exterior of the tube, which is rotated by a pair of wedges or other cam members relatively to a clamp which holds the tube &c. on all sides, the degree of twisting being determined by the current of rotation of the tube over an extent of its length determined by the distance between the rotary part and the clamp. The tool may comprise a platform 1 provided with walls 2 supported on the bed of a press and having a central hole 3 through which is passed the tube &c. 11 which is held in a grooved clamp 10 depending from the platform by a cover-plate held fast by wing nuts 13 or by a toggle, wedge, eccentric or cam mechanism. Round the hole are provided a pair of raised bearing blocks 8, 9 for the twisting member 14, which has an aperture 15 corresponding in shape to the tube and is provided with radial arms 16, 17. This member is rotated by slides 6, 7 moved in slots 4, 5 in the platform, preferably against the action of springs, by wedges 18, 19 which are pushed down by the press ram and returned by springs. The wedges are secured to-members guided in transverse slots at the ends of the slots 4, 5. The amount of twist is limited by stop plates 24, 25 secured by bolts 26 in tapped holes in the platform. The length of the part being twisted may be varied by adjusting the clamp towards and from the platform and it may be further varied by using a member 14 with a central portion projecting into the hole 3. The edge of the aperture in the member 14 is rounded to prevent marking of the tube. The tendency for the work to incline over to one side is eliminated by a ramp 28 engaged by one of the radial arms. The clamp may be interchangeable to suit different shapes of tubes. The parts may be of wood with working surfaces of hard fibre or other wear-resisting material. The tube to be twisted may be filled with a low melting point alloy, sand, or resin, &c.
