Filed: 1943-05-19
Abstract: Quinoline derivatives which are intermediates for the manufacture of spasmolytic agents, diethyl g -quinolyl-1, 4-dihydro-a a 1-lutidine-b b 1-dicarboxylic esters, are prepared by reaction of a quinoline aldehyde with ethyl b -aminocrotonate, or a mixture of ethyl acetoacetate and ammonia, preferably in the form of an alcoholic solution.  In examples, g -2, -3, -4, -5, -6 and -8-quinolyl - a a 1 - dihydrolutidine - b b 1 - dicar - boxylic diethyl esters are prepared.  The aldehydes, including quinoline-3 and -5-aldehydes, are prepared from the carboxylic acids.  The g -6-quinolyl-a a 1-dihydrolutidine-b b 1-dicar boxylic diethyl ester may be converted by oxidation with nitric acid to g -6-quinolyl-a a 1 lutidine-b b 1-dicarboxylic diethyl ester which may be saponified to g -6-quinolyl-a a 1-lutidine-b b 1-dicarboxylic acid and heating thereof or its silver salt gives g -6-quinolyl-a a 1-lutidine which is a spasmolytic agent.

Title: Improvements in or relating to the mounting of scanning coil assemblies on cathode ray tubes
IPC: H01J29/82
Filed: 1956-03-17
Abstract: 818,990. Electron beam defecting apparatus. COLE Ltd., E. K., and LEVI, J. E. March 18, 1957 [March 17, 1956], No. 8402/56. Class 39(1). The scanning coil assembly of a television receiver or other cathode ray tube is held in position against the flared portion of the tube envelope by means of a split annular wedge of polythene or other resilient plastic material which is urged by a clamping plate K, Fig. 2, to a position between the coil assembly and tube neck where it grips the tube neck and holds the scanning coils in correct centred position and, by urging the scan coil assembly against the flared part of the tube in correct longitudinal position while permitting frictional rotary adjustment of the scan coil assembly about the tube neck to adjust the angular position of the image on the screen. The scan coil assembly is slid as a single tubular unit on the tube neck, and comprises four coils A, B, C. An adjusting lever E for manually rotating the scan coil assembly supports struts for plate K; preferably of adjustable length, are secured to a bracket encircling the front of the cathode ray tube the wedge M has tapering surfaces at both ends e.g. is formed as a truncated right angled isosceles triangle in cross section and has an integral projection N which passes into or through a recess or opening in clamping plate tapered flange P. to prevent rotation of the wedge when the coils are rotated The internal diameter of the wedge, which is split, is slightly greater than the external diameter of the tube neck so that when pressure is applied by plate K the wedge is urged between the coils and tube neck to grip both the tube neck and scan coils. The gap between the split ends of the wedge registers with a second aperture in the plate flange P so that electrical leads to the scan coils can be brought through both gap and second aperture. An additional coil spot wobble coil mounted on a paper backing may be wrapped around the tube neck underneath the wedge or can be embedded in the wedge. In these cases the wedge must not rotate so projection N is required but if the wedge can rotate projection N may be dispensed with.

Abstract: 472,322. Photo-electric control of projectile fuzes. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 21, 1936, Nos. 8520 and 8521. Convention dates, April 2, 1935 and Oct. 14, 1935. [Class 40 (iii)] A projectile is provided with a source of light 2 adapted to throw out a beam of light on a target, for example, an aircraft, and a light-sensitive cell 4 adapted to receive the light reflected by the target and to cause thereby the ignition of a primer 12 to explode the projectile. The source of light may be an aluminium or magnesium cartridge ignited a given time after the discharge of the projectile, and the light may be emitted evenly around the projectile through holes 3. The light reflected by the target is received in the projectile through holes 13 and passed by a conical prism 14 and a lens 17 to the cell 4 which may fire the primer by means of a relay 6 adapted to close the primary circuit of a transformer 8, the secondary circuit of which is coupled to the primer 12. Preferably the emitted light beam is made intermittent, for example by an arrangement of a few holes 3 only around the projectile. The intermittent actuation of the cell 4 then operates through a filter transformer and condensers 18, 19, 20, and a rectifying device 21, the direct current from which operates the relay 6. In this way the apparatus is unaffected by the uniform light of day. A safety switch 10 closed after a given time is put in the firing circuit.

Filed: 1945-04-06
Abstract: 591,881. Machinery guards. STRACHAN & HENSHAW, Ltd., SARGENT, T., BARNETT, S. H. G., and KNIGHT, E. J. April 6, 1945, No. 8560. [Class 80(iv)] The knife beam 2 of a guillotine cutting machine is adapted to be positively held from making its working stroke by the engagement of a safety bar 7 with a catch bar 1 on the beam 2 should the guard 10, 11 not be in the closed or safe position. The bar 7 is carried on arms 6 secured to a shaft 4 mounted in brackets 5 of the machine and moves into the operative position, as shown in Fig. 4, to engage the catch bar 1 under gravity when the guard 10 is open. The guard 10, 11 is pivoted on levers 15 freely pivoted on the shaft 4 and also pivoted on levers 17 carried by a crossshaft 18. Also secured to the cross-shaft 18 is a lever 40 with a roller 44 adapted to engage a slot 50 in a bushed lever 30 which is slidable and rotatable on the shaft 4 together with a slotted plate 31 and a collar 32. Through a hole in this lever 30 passes a cross-bar 52 carried by arms 5, 3 secured to shaft 4. From the position shown in Fig. 4 with the guard open and the safety bar 7 engaging the beam 2 to prevent the stroke of the knife the guard 10, 11 must be pulled down manually by the operator grasping the bottom connecting rod 12 of the guard to the closed position shown in Fig. 5. Towards the end of this operation the roller 44 of lever 40 engages in the slot 50 of lever 30 and pushes it backward, which movement is transmitted to crossbar 52 and its supporting arms 53 to actuate the shaft 4 carrying the safety bar 7 to move the latter clear of beam 2, as shown in Fig. 5, to allow the knife to descend. A further lever 20 on shaft 18 also engages the end of a slot 22 (see Fig. 3) in a bar 23 to move the end 25 of this bar out of interference with an operating lever 8 for initiating the stroke of the machine. The guard cannot be lifted until the end of the working stroke since the roller 44 of the lever 40 locks itself in the slot 50 of lever 30 owing to the backward movement of this latter lever. Towards the end of the stroke, however, a vertical arm 36 secured to the knife beam, which has a sideways movement as well as vertical, engages a stop 34 on the plate 31 to move the lever 30 sideways to disengage from the roller 44 which allows the guard to be raised by the operator, or by a counterweight 19 on the shaft 18, to the cpen position. The safety bar 7 engages with the beam again when the beam has returned to its raised starting position. In a modified arrangement the mechanism for laterally moving the lever 30 to disengage from the roller 44 at the end of the working stroke is dispensed with and the lever 30 is secured directly to the shaft 4 so that the roller 44 actuates through the lever 30 and shaft 4 the safety bar 7 directly. In this arrangement the guard is locked in the closed position until the knife beam is fully raised to its starting position to allow the safety bar 7 to move back under the catch bar 1. Specification 517,659 is referred to.
