Title: Improvements in or relating to luminescent materials and to electric discharge tubescontaining such materials
IPC: C09K11/08
Filed: 1950-07-13
Abstract: 702,527. Luminescent materials. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 13, 1950 [July 16, 1949], No. 17555/50. Class 39(1) A discharge tube comprises a self-activated luminescent substance the lattice structure of which is built up from at least one element from each of the following groups: (1) zinc and cadmium, (2) sulphur and selenium, (3) aluminium, to an extent of 10<SP>-5</SP> to 30 atoms per 100 atoms of zinc and cadmium. The aluminium takes over the function of the trace of halogen in a self-activated luminescent substance, so that an optimum supply of a halide flux may additionally be included, preferably a fluoride of one at least of aluminium beryllium, magnesium, calcium, strontium, barium, zinc and cadmium, since fluorine is non-effective in self-activation. In an example, zinc sulphide is moistened with a solution of Al(NO 3 ) 2 , allowed to dry, then heated at 1200‹C in an H 2 S atmosphere for one hour. The product has a blue luminescence, a maximum at 4600Š.

Title: Feeding fluid under pressure
IPC: F15B11/17
Filed: 1974-04-22
Abstract: 1427105 Valves POCLAIN 22 April 1974 [28 May 1973] 17559/74 Heading F2V [Also in Division F1] A constant delivery pump 1, Fig. 1, supplying a priority circuit 28 and a variable delivery pump 2, supplying a circuit 14, have their combined power requirements maintained within the available power of a common drive motor 3 by a valve 29 and a regulator 16 which control the output of the pump 2. The valve 29 has a spring-loaded piston 31 with a groove 43 which connects inlet and outlet orifices 40, 53, and a bore 42 which connects inlet 40 with outlet 41. If the load on pump 2 begins to rise to an unacceptable value, the increase in pressure is transmitted through a line 36 to valve 29 where it depresses the piston 31. Because the length of the constricted groove 43 is shortened as the piston 31 descends, a higher pressure is transmitted from the outlet 41 to a piston 45 through a line 50. This raises a rod 18 against springs 25 and decreases the output of the pump 2.

Abstract: 199,950. Tucker Eyelet Co., Ltd., G., and Turner, S. July 6, 1922. Fastenings.-In a machine for making lacing-hooks from strip metal of the type in which after a series of operations by one set of tools, the article is cut from the strip and is carried by means of a tansferring-slide to a second set of tools, means are provided automatically to stop the machine should the transferring-slide fail to function. A reciprocating gripper 7, Fig. 1, supplies strip stock to be successively operated on by tools 11 - - - 17, the latter of which cups and cuts out the blank which is then received by the transferring-slide 18. The transferring-slide is provided with a bending-die and carries the blank beneath a bending-tool by which it is bent to the required hookshape and by which it is withdrawn from the slide. The transferring-slide is moved in one direction by a cam-operated lever 20 and horizontal link 19, Fig. 5 ; and is spring-returned. Should failure to return occur, owing to non-removal of the hook, a shoe 47 on the lever 20, Fig. 7 which normally swings clear, remains in the path of a gravity pawl 51, carried by a rod 38 which is vertically guided in lugs 39 on the press slide 1 and is urged upwards by a spring 46. The continued upward movement of the press slide rocks a trip lever 41, which is pivoted to a bar 37 rigidly secured to the rod 38, and thereby disengages the rod 32 from an arm 28 secured to a belt striking-rod 23, Fig. 1. The latter on release is actuated by a spring 25 to throw the driving-belt on to the loose pulley, so stopping the machine. On removing the obstruction and re-starting the machine the trip mechanism is automatically reset by the springs 35, 43, 46. Specification 18656/07 is referred to
