Abstract: 1,054,861. Cathode-ray tubes. RAILLAND CORPORATION. Aug. 29, 1963 [Aug. 29, 1962], No. 34199/63. Heading H1D. A method of establishing a light-absorbing design on a screen support of a cathode-ray tube comprises the steps of:- (a) applying a coating including a lightsensitive resist and a material which has a relatively low absorption to light and which in response to the application of heat becomes increasingly absorptive to light; (b) exposing said coating by projecting thereon a desired image in light; and (c) removing unwanted areas of said coating and heating the remaining areas. The method is applicable to screens of the dot or linear elemental area type in monochrome or colour tubes, and the light absorbing materials may be applied before or after forming the phosphor dots or strips. In one example, phosphor dots applied by a known photo-resist method are rendered substantially non-transparent to actinic light either by coating with a dye or by heating to well below the decomposition temperature. The whole screen is then coated with a photo-sensitive resist which is normally soluble in a given solvent but becomes insoluble when exposed to light and contains a manganese compound such as the carbonate or oxalate which decomposes to black manganese dioxide when heated. The screen is exposed to actinic light from a source disposed on the opposite side to that bearing the coating to fix and render insoluble those portions of the resist between the phosphor dots. The remaining portions covering the dots are then washed off and the screen heated, preferably during the bake out processing of the tube to deposit the phosphor and light-absorbing compounds and to decompose the manganese compound. The light-absorbing material may be applied before the phosphor dots by exposing a resist of the negative type through the shadow mask of the tube.

Abstract: 1,251,335. Brakes. DUNLOP HOLDINGS Ltd. 20 Feb., 1969 [24 Feb., 1968], No. 9048/68. Heading F2F. In a self-servo master braking cylinder 1, the forward movement of the vehicle body on its suspension relative to the wheels is used to drive in a plunger 7 to feed a magnified pressure to the braking outlet 23. When the driver initially applies his brakes, pressure from cylinder 41 passes through connection 39, through an input chamber 15, through a central bore in the end portion 16 of a slidable sleeve 5, through a slot 22 in the side of a rod 19 projecting from plunger 7, and so into a pressure chamber 18. From this chamber, the fluid passes through radial drillings 34 to a groove 28 on the sleeve facing a groove 26 on the body and connected to the outlet 23 to the brakes. Thus the pressure from cylinder 41 acts directly on the brake. The self-servo cylinder 1 is connected between the vehicle chassis 4 and the anti-roll bar 11 at eye 9, 10. Braking causes movement between these which forces the plunger 7 into the cylinder. This causes the end 22 of the slot 21 to cut off within the bore in the end 16 of the sleeve. This seals the pressure chamber 18 so that further movement of the plunger 7 forces fluid at an increased pressure out at outlet 23 to the brakes. If this pressure becomes excessive, the pressure acting on the shoulder of the sleeve end 16 moves the whole sleeve against the pressure in chamber 15, thus closing groove 26 and opening a groove 27 which vents into chamber 15 to the brake outlet 23, thus relieving excess pressure. The ratio of the shoulder area to the head area of the whole sleeve acting as a piston at chamber 15, governs the ratio of magnification of the applied pressure, in this case, about 7¢ times. Excessive movement of the sleeve closes port 28 and opens a port 27 to the brake outlet, this venting through channels 29, 30 back to chamber 15. The device may be applied to aircraft as well as road vehicles. The openings 27, 28 may be wedge-shaped to produce a graded effect.

The means on which the jaw 19 is mounted is a threaded pin 17 screwed into the jaw 9 at right angles to a face 16, the pin being surrounded by a sleeve 18 fixed to the jaw 9 and provided with an internal thread; the jaw 19 has an aperture for receiving the sleeve 18 and is prevented from rotation relative to the jaw 9 by means of a lug 21 which engages in a recess 20 of the jaw 9. The jaw 19 has a serrated clamping surface 22 for engaging the strip 7. The jaw 19 is moved to clamping position by a rotary knob 23 threaded onto the free end portion of the pin 17. The slide 3 is provided with an inner channel for receiving the window pane 5 and an outer channel for receiving a window pane 6 and the window pane 6 carries a clamping device which is also engageable with the strip 7; the only difference between the clamping device for the window pane 6 and that for the pane 5 is that a spacer (25), (Fig. 7, not shown), is disposed between the base plate 10 of the jaw 9 and the face of the pane and the screws 10a are slightly longer to allow for the thickness of the spacer. The slide 3 has longitudinal ribs formed on the bottom of each of its channels to reduce frictional resistance. In a modification is is stated that the jaw 19 instead of being moved by the knob 8 can be moved to clamping position by a cam.

Abstract: 1,258,222. Testing coins. VENDALL MACHINES Ltd. 23 Feb., 1970 [14 April, 1969], No. 8505/70. Heading G4V. Coins of above a minimum size falling from shoot 11 in a channel between vertical plates are caught by a cradle (12, Fig. 1, not shown) which then tilts to deposit the coins on runway 9. Ferrous slugs are held by magnet (13, Fig. 2, not shown). The speed at which the coins leave runway 9 is affected by eddy currents induced by magnet 10. Fast moving coins of brass or other low conductivity metal strike anvil 21 and rebound to the left of separator 40. Genuine coins of silver or other medium conductivity metal leave the runway at an intermediate speed and fall to the right of separator 40, whilst slow moving copper coins, i.e. those of high conductivity fall to the left of the separator. Nickel coins, which would otherwise be stopped by magnet 10, are attracted by magnet 16 so that they swing open spring-biased gate 17 in plate (1) to travel along guide (18) at the rear of plate (1) until they fall through aperture 20 into the path of the other genuine coins, thus by-passing magnet 10. Stops (45, 46) limit the forward and rearward movement of gate 17 about pin (41). Anvil 21 comprises the lower part of sweeper 22 which is pivoted at 29 and biased by spring 32 against stop 33, whose position may be finely adjusted by screw 38 to control the normal position of anvil 21. On operation of a coin return lever, roller 23 is depressed, causing member 24 to pivot about 25. Pin 30 thereby produces a clockwise rotation of arm 22 so as to sweep coins held by magnet 10 into the coin return path, whilst cam 27 moves roller (28) so as to rotate plate (3) and thus move runway 9 from the path of arm 22.
