Title: Device for stacking carton blanks and the like
IPC: B65H33/16
Filed: 1963-01-14
Abstract: 1,007,044. Delivering sheets. SUNDS VERKSTADER A.B. Jan. 14, 1963 [Jan. 18, 1962], No. 1594/63. Heading B6H. Sheets, e.g. carton blanks, from a stack 14, Fig. 1A, are conveyed by endless belts 7, pressed upwards by springs 10 against belts 9, and then carried by belts 8 in underlapping formation, the belts 9, 8 moving more slowly than the belts 7, to the underside of a stack 1, Fig. 1B. Each sheet delivered raises the stack and is stopped by an abutment 6. When a predetermined number of sheets is detected by a microswitch 6 and counted by a counter 66, an electromagnet 49 is energized to lower the abutment 6, whereupon the stack moves forwards as shown at 65. The abutment 6 is immediately released and urged upwards by a weak spring 67, so as to rise to locking position as soon as the stack passes off it. If two sheets are not underlapping, this is detected by a photo-cell 60, and a magnet 62 raises plates 61 to lift the trailing end of the stack until (because of a delay device 69) the next sheet is fed into the stack. In another form, Fig. 4, sheets reaching the stack are not underlapped, since belts 71 running on enlarged-diameter parts 74, 75 of rollers 72, 73, over which the conveyer belts 16 also run, accelerate the sheets. Each sheet as it passes wholly into the stack is counted by apparatus 77 under control of a photocell 76, and after a predetermined number have been counted, a motor 78 rotates a shaft 80 through half a revolution, the shaft 80 carrying two opposed spring-actuated abutment flaps 81. Alternatively, the shaft carries one abutment and is rotated a complete revolution. In another form, the shaft 80 is rotated by friction with the belts 16, and stopped after half a revolution by a blocking member which may be the armature of the magnet 49. In all the formed described, the belts 9 and some of the rollers carrying the belts 7, 8 are carried on a slide adjustable longitudinally by a hand wheel for adjustment according to sheet length, while another hand wheel adjusts the position of the stacker and abutment mechanism.

Patent GB-994551-A (GB)
Title: Method and apparatus for bending and annealing glass sheets
IPC: C03B23/027
Filed: 1963-01-16
Abstract: <PICT:0994551/C1/1> <PICT:0994551/C1/2> In a method for bending and annealing glass sheets on a skeleton mould, heating means carried by the mould within the confines of its shaping surface is operable to heat preselected areas of the sheet during engagement of the bent sheet with the shaping surface. A three-part mould 11 comprises substantially continuous sloping rails 13 and, within the confines of the rails 13, a substantially continuous strain bar 15.  The strain bar 15 comprises centre sections 36 and end sections 37, each section carrying an electric resistance heater which is connected to the heaters of its adjacent sections by flexible conductors 46.  One of the sections 36 of the strain bar 15 has a gap 45.  Two coupling means 41 (Fig. 4), are mounted, on either side of the gap 45, on a rack 12 that supports the mould 11 and are connected by flexible conductors 43 to the electric heaters on their respective sides of the gap 45.  Each coupling means 41 includes a wheel 47 with an outwardly-opening groove 48 journalled on a rod 49 in one end of an arm 50. The other end of the arm 50 is supported by a pin in a clevis bracket 52. Each arm 50 trails behind the rack 12 as it travels through a tunnel furnace and is raised to the position shown in Fig. 4, from its initial position shown by dotted lines in Fig. 4 and determined by abutment surfaces 54, when it meets and rides up upon one of two generally rectangular bus-bars 40 mounted within and along part of the length of the furnace.  Heating of the strain bar 15 is commenced while the mould 11 is in the bending zone and is discontinued at a point within the annealing zone of the furnace, the timing and duration of the heating being determined by the positioning along the length of the furnace and the length respectively of the bus-bars 40. The use of the heated strain bar 15 intensifies and permits more accurate control of the differential cooling of a bent glass sheet effected by the use of a conventional strain bar, and similarly produces areas of tension and compression in the bent sheet so that when subsequently pattern-cut the peripheral edge of the cut bent sheet is in compression.  The heat supplied to different parts of the strain bar 15 may be varied by the suitable choice of resistance values for the individual heaters. The resistance heaters may be mounted on the top or bottom surfaces of the strain bar 15 or alternatively, may be disposed within a hollow strain bar.  The strain bar 15 may also carry conventional heat shields.  Other means for heating the strain bar 15 include directing flames on it or constructing it in the form of a conduit through which a heating fluid is passed.

Title: Improvements in or relating to cartridges and the like tubular containers for use in dispensing liquids
IPC: A61M5/31
Filed: 1953-02-22
Abstract: 743,789. Hypodermic injection appliances. SCHOFIELD, H. P. May 24, 1954 [Feb. 22, 1953; March 17, 1953; April 10, 1953; Jan. 15, 1954], Nos. 2144/53, 7373/53, 9785/53 and 1186/54. Class 81(2). A syringe cartridge is provided with a piston stopper at one end and, at the other end, an assembly comprising a cap and needle, so formed as to be non-retractable during the injection. In the preferred form the barrel 20 carries a cap 24 which is sealed by a rubber ring 28 in a stepped groove 27 so that the cap can only be pressed inwards. Such movement causes the inner end of the needle to pierce a diaphragm 21 and permit the contents of the cartridge to be expelled by pressure on the piston 32, by a rod which, if desired for aspiration, may be screwed into a threaded recess 37. To permit any enclosed air to be expelled, a duct 34 holds a closure rod 35, the inner end of which is fluted. This is withdrawn slightly, to allow the air to escape, and is then pressed fully in to seal the aperture. The diaphragm may be formed as part of a non-retractable plug, instead of integral with the cylinder, and in this case the mounting carrying the needle is supported in a bore in this plug and may have a chamfered end for breaking the diaphragm. If it is intended that the cartridges shall contain two separate medicaments they may be initially separated by an intermediate plunger having an axial bore which is closed by a ball. When the appliance is to be used the ball is forced out of position by the pressure of liquid behind it, and this liquid is then free to pass into the second compartment, see Fig. 2 (not shown). Specifications 728,816 and 743,839 are referred to.
