Title: Improvements in or relating to x-ray image amplifiers
IPC: G21K4/00
Filed: 1952-01-14
Abstract: 709,764. Luminescent screens; cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 14, 1952 [Jan. 17, 1951], No. 1029/ 52. Class 39(1) An image intensifier for use with X-rays which is provided with a luminescent screen excited by the X-rays and placed near the photo-cathode is characterized in that this luminescent screen comprises a luminescent material which is embedded in a siloxane which is lucid and transparent, and which is constituted by the polymerization at gradually increasing temperature of a siloxane of which in its liquid state the molecular weight is not more than 2000. The screen may be formed integrally with the photo-cathode, as shown in Fig. 2, and may comprise a plate 9 of aluminium or beryllium, which is transparent to X-rays, arranged in a frame 11. The luminescent layer 10, which may be between 0.2 and 0.7 mm. thick, if formed on the plate 9 by casting a suspension of luminescent material, such as zinc sulphide which may be mixed with cadmium sulphide, in silicone on the carrier; more silicone than necessary may be used so that after settling a layer of pure silicone remains on top. The screen is then heated up to about 200‹C. in about 8 hours so that the silicone polymerizes. A thin layer of alumina 13 may be deposited on the fluorescent layer, followed by a thin layer 14 of chromium or iridium and a photo-sensitive layer 15 which may be of silveractivated caesium oxide or antimony and caesium oxide. After the silicone has hardened the screen may be curved to form a spherical surface, the photo-sensitive layer being applied subsequently. The screen may be mounted in the image intensifier by means of resilient members 16 which may bear on a wall coating on the wall of the tube to provide an electrical connection to the screen as well as a mechanical support. The silicone preferably has a refractive index of about 1.5 and may be of the material known by the trade name of "Silicone 804 ".

In manufacturing a cathode-ray tube screen by the photo-resist method, and particularly in colour image-reproducing tubes for the layer from which the indexing elements are formed, a layer, non-reflective of light of a colour to which the photo-resist layer is sensitive, is applied first in order to prevent reflection of the sensitizing light into unwanted areas of the photo-resist layer, particularly from the aluminium light-reflecting film on which the indexing elements are formed. The layer 15 may be of a red dye and is subsequently removed by baking. Specifications 713,908 and 802,908 are referred to.

Abstract: 1,116,497. Control of D.C. motors. SEVCON ENGINEERING Ltd. 9 Jan., 1967 [11 Jan., 1966], No. 1170/66. Heading H2J. A series traction motor is supplied from source M which may be an external D.C. supply, a diesel-driven generator, or a battery. The field winding F is additionally excited from source P, which is a mark-space ratio device employing silicon controlled rectifiers, to limit the maximum speed at which the motor drives the vehicle. If the motor is over-driven, regenerative current passes through diode D2 to the source M, the field current being maintained by the pulse source. Diode D1 prevents current from the source P from passing through the armature, and diode D3 prevents feed-back from the source M to the source P.

Abstract: <PICT:1036741/C1/1> A moulding machine for moulding the faceplate of a shadow-mask colour television tube and with provision for inserting metal eyelets in the faceplate during the moulding operation, the eyelets being used for the mounting of the shadow mask (see Division H1), comprises a dish section 60, a plunger section 61 and a two-part retaining ring 62, the plunger section being equipped with three compressed-air-operated pistons 68.  Each piston 68 has a plunger rod 71 for first forming a recess in a boss portion 44 of the molten glass charge 21 forming the faceplate and then for feeding an eyelet 42 supplied from a magazine 75 into the recess. The eyelet is heated by gas jets 76. After the glass is allowed to cool the faceplate is annealed by raising it to a temperature of about 500 DEG  C. and then slowly reducing the temperature at a rate of about 2 DEG  C. per minute to a terminal temperature of 350 DEG  C.  The plunger section of the moulding machine has cooling fins 63 and is water-cooled.  In an alternative method of providing metal eyelets in the faceplate blank metal pads, e.g. of stainless steel, are first-sealed into recesses in the faceplate after the faceplate has been moulded and annealed. Recesses are then drilled in the metal pads (see Division B3).  The faceplate may be formed of glass having a thermal coefficient of expansion of 10.4 x 10-6 per  DEG C., the frit of glass having a thermal coefficient of 10.5 x 10-6 per  DEG C. and the steel having a thermal coefficient of 11.4 x 10-6 per  DEG C.

Title: Improvements relating to internal combustion engines
IPC: F02B75/28
Filed: 1943-01-27
Abstract: 565,276. Four-stroke and two-stroke engines. GREEN, A. A., and WEINREB, F. Jan. 27, 1943, No. 1419. [Class 7 (ii)] An internal-combustion engine has only part of the compression effected by the main piston 2, an auxiliary piston 5 being arranged to follow up the main piston on the working stroke, and ignition taking place when the crank has advanced about 35 degrees from dead centre and part of the combustion taking place at decreasing volume owing to the continued movement of the auxiliary piston towards the main piston. The auxiliary piston 5 is operated from a cam 16 through a roll-carrying link 12, rocking lever 7, and rod 10. The roller 15 is maintained against the cam by a spring 17 acting on a link 13. The cam is timed so that when the main piston is at inner dead centre M-M the auxiliary piston is at AA. As the main piston moves on its firing stroke the auxiliary piston is moved faster in the same direction by the cam rise ab so that further compression reaching a maximum when the crank is about 35 degrees past T.D.C. is obtained, whereupon ignition takes place (position shown on drawing). The cam part bc causes continued movement of the auxiliary piston so that part of the combustion takes place at decreasing volume. The exhaust stroke is made with the auxiliary piston at A<1>A<1> (cam part d, e). During the suction stroke the auxiliary piston is moved back to A<2>A<2>. The point h of the cam, reached on the following compression stroke, corresponds to the starting position AA. Additional fuel may be injected into the cylinder during the expansion stroke. The auxiliary piston 5 is bevelled off and channelled at 20, 22 so that when this piston is withdrawn, air or mixture may pass from a port 23 into the cylinder. This port may be fitted with a valve. The cam 16 may be axially movable on its shaft and have different contours at different points along its length so that it may be adjusted to give maximum compression at any desired crank angle and reversing of the engine may be effected. The invention may be adapted to two-stroke engines and also to compressionignition or otherwise ignited engines.
