Abstract: 720,662. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 4, 1953 [Feb. 7, 1952], No. 3164/53. Class 39 (1) A permanent magnet lens comprises two coaxial tubular members, the ends of which are coupled by flanges, the inner member having an annular air gap axially adjustable by a tubular shunt held coaxially adjustable within the lens by a plurality of leaf springs arranged in spaced planes perpendicular to the lens axis. A tubular permanent magnet 1 supports flanges 7, 9, the air gap 5 in which is adjustable by a soft iron shunt 13 supported on annular flat springs 15, 17 which are .carried by the flanges 7, 9 through bolts 19, 21 and spacers 23, 27.

Title: Apparatus for application to automatic machines for the manufacture of phials or of other bodies of glass with semi-spherical bases
IPC: C03B23/11
Filed: 1950-02-08
Abstract: 736,391. Making glass phials &c. GUSTI, A. Feb. 8, 1950 [Feb. 8, 1949], No. 3235/50. Class 56. A rotary or linear machine for the manufacture from glass tubing of phials or the like has a conduit 10 for supplying compressed air in the bottom forming operation which has at its end a plunger-like body operable within the interior of the tube, air being passed between the plunger and the bottom of the tube while the latter is still heated to transform the bottom of the tube to semi-spherical shape. The glass tube is heated, drawn out, formed with a neck, and cut by burners, whereupon the phial is released and the remaining tube heated at the bottom, blown to form the rounded base, cooled and lowered on to a spring support which is adjustable to give the required length for making the phial. The rounded base is then gripped for a repetition of the cycle. The machine shown has eight mandrels located in a frame formed of uprights 2, lower plate 3, and upper ring 1. The gas and air distributers are formed by a disc 4 fixed to the centre shaft 5, a lower disc 6 which rotates with disc 3, and four concentric rings 13-16 therebetween. Arcuate grooves 28 are provided in the rings 13-15, each with a central threaded hole to receive a tube 14a conducting the gas mixture. Ring .16 has an arcuate groove 16a adjustable by displaceable blocks 17, 18 and connected by pipe 19a via regulator 19 to an air compressor. Rings 13-16 are independently angularly adjustable. As disc 6 rotates holes 20 therein communicate with the arcuate grooves 28 and respectively with necking burners, cutting burners, and the burners for heating the base of the tube, and eight equally-spaced holes 29 each connected to a pipe 8 communicate with groove 16a, the duration of these communications depending on the length of the grooves and the timing on the positioning of rings 13-16. The tubes 8, attached to ring 1, are provided with cocks 9, and connected by means of a rubber pipe 21 with the tubular extension 10 of the shaft which grips the glass tube 12. Tube 10 terminates in a piston 11 which is inserted in the rotating glass tube and has circular channels forming the air-tight body. This piston may be replaced by a rubber cap 27 which is deformed under air pressure to form an air-tight seal, the cap conveniently being of conical form so that it may be cut to suit the diameter of the glass tube. Groove 16a communicates with the atmosphere to prevent deformation of the tube by the dilation of air remaining in the tube.

Title: Improvements in hoisting apparatus
IPC: F15B11/044
Filed: 1950-02-08
Abstract: 669,710. Hoisting - apparatus. SUNDIN, E. O. Feb. 8, 1950. [Dec. 17, 1949] No. 3254/50. Class 78 (ii). In fluid-pressure actuated hoisting apparatus of the kind comprising a piston axially displaceable in a cylinder which is connected at its lower end to a pump for supplying pressure fluid through a conduit containing a regulating valve and a check valve and including also a pressure reducing valve for enabling the load to be lowered at substantially the same speed whether it be heavy or light, the pressure reducing valve 23 includes a valve member 25 provided with a stem 27 carrying a piston 28, the conduit 17 which passes fluid to the valve during lowering of the load is connected to the valve housing at a point between the valve 25 and the piston 28, and the effective area of the underface of the valve 25 is greater than the effective area of the piston 28. A coil spring 32 which is compressed between a nut 30 on the valve spindle and a member 33 screwed into the valve housing, maintains the valve open when there is no flow of pressure fluid through it. During lowering, pressure fluid flows strongly in the direction of the arrow and the increase of pressure in the chamber 36 forces the valve member 25 upwards against the resistance of the spring, thus reducing the effective flow area. A pin 34 limits the downward travel of the valve member 25.

Abstract: <PICT:0451261/IV/1> Stockings are placed toe-upwards on upright forms carried on a conveyer device and are moved thereby through a series of liquid treatment processes, free access to the forms being provided between washing and dyeing points of treatment so that the stockings may be readjusted and tensioned on their forms.  The stockings may be slipped over the forms at the operator's position A and be carried on the conveyer device 1 through a chamber 2 in which nozzles 3 spray a washing liquid on to both sides of the stockings to free the stockings from fat.  Rinsing, preferably with pure water occurs in an adjacent chamber 4.  Dyeing liquor is sprayed on to the stockings by nozzles 7 in a chamber 6 which is spaced away from the chamber 4 so as to provide a free section of track 8 where the washed stockings may be again tensioned and stretched on their forms. Further accessible sections of track 10, 12, 16 respectively, may be provided between the chamber 6 and a rinsing chamber 9, the rinsing chamber 9 and a treating chamber 13, where the lustre may be subdued, and the chamber 13 and a mechanical treating device 15 where the forms are passed between ironing or squeezing rollers, at all of which sections the stockings may be stretched.  The stockings may be removed at the operator's position B and placed on a second conveying device passing through a drying chamber, or the same conveying device may also carry the stockings through a drying chamber.

Abstract: 469,827. Endless-chain conveyers. ROBINSON, Ltd., E. S. & A., ROBINSON, H. G., and COOPER, A. B. Feb. 4, 1936, No. 3368. [Class 78 (i)] [Also in Group XVII] The rectangular end-flaps of a carton are closed by folding in first one of the wide flaps, then the pair of narrow flaps and finally the other wide flap, adhesive being applied between the flaps. After closure the cartons are delivered in stacked formation to a conveyer which grips the ends to ensure setting of the adhesive. The apparatus is adjustable for different sizes of carton. A platform 37 is moved horizontally by a crank 60 and the carton carried thereby is delivered to a pair of gripping plates 38. As the platform 37 returns, an ejector 44 rises and lifts the suspended carton into the space between the conveyer bands 15. As these operations are repeated, a stack of cartons is formed between the bands 15, and when a predetermined number of cartons have been stacked, the conveyer advances a step, and a fresh stack is started. The conveyer is advanced intermittently through a clutch 51, 52 under the control of a selector disc 54, which is driven slowly from the shaft 66 and is provided with one or more notches as desired to allow a member 53 to be retracted and the clutch 51, 52 to be engaged. The distance between the conveyer bands 15 is adjusted to the length of the cartons by a wheel 18 on the end of a screw-threaded shaft 19.
