Title: Improvements in or relating to conveyor systems
IPC: B65G47/48
Filed: 1939-08-02
Abstract: 531,800. Conveyers. KING, Ltd., G. W., and KING, D. M. Aug. 2, 1939, No. 22432. [Class 78 (i)] Carriers or other containers carried by an endless conveyer chain are discharged automatically at any one of a number of pre-selected stations. In the illustrated form the carriers 11 are connected to an endless driving chain 10 supported from the girder 13 by wheeled hangers 12. Each carrier is fitted with a slotted plate 14. By rotating the rods 19 and moving them axially by hand, their projecting ends 20 can be set in various positions in the slotted plate; each position of the pair corresponding to preselection of a discharging station. Plates 22 near each discharge point have a pair of holes 23 adapted to register with the ends 20 when set for that point. As the carriers pass non-selected stations, they push the plate 22 laterally out of the way, but at the pre-selected station, the projections 20 enter the holes 23 and the plate 22 is linked to the moving carried @ thus moved in the guides 22. The moved plate operates the linkage 26 to raise a ramp 27 which in turn contacts the roller 28 and raises the lever 29 and link 31 to tip the receptacle 30. A cam separates the plates as the carriers pass beyond the discharge point.

Title: Improvements in or relating to devices for amplifying voltages
IPC: H05B33/22
Filed: 1956-07-23
Abstract: 838,438. Electroluminescence. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 23, 1956 [July 26, 1955], No. 22718/56. Class 39(1). [Also in Groups XL(b) and XL(c)] A device for amplifying voltages comprises a glass tube 16 on the inner surface of which is an aluminium foil electrode 22 covered with a thin layer of reflecting material (TiO 2 ) 23 on which is a layer of electroluminescent material 24, e.g. ZnS suspended in a dielectric, covered with an electrode 25 which can be a thin layer of transparent conductive material such as SnO 2 , a light permeable metallic layer or a metallic grid. A central rod 19 of photoconductive material such as CdS is provided with aluminium electrodes 17 and 18 at its ends and is spaced from the electrode 25 by an insulating ring 26. The thickness of the electro-luminescent layer 24 is about 50 microns and the photoconductive rod 19 has a thickness such that substantially the whole of it is utilised in the absorption of light. The light emitted from the electroluminescent material 24 includes U.V. and I.R. radiations. The photo-conductive material can be a semi-conductor, the specific resistance of soluel is varied by light, or a dielectric, the dielectric constant of which is varied by light. The voltage to be amplified can be applied to an input impedance connected, in series with an auxiliary voltage source, between the electrodes 22 and 25 of the electroluminescent layer 24. The auxiliary voltage source may supply a D.C. biasing potential on which the voltage to be amplified is superposed, or may be an A.C. voltage which can have a low frequency with respect to that of the voltage to be amplified, the amplitude of the auxiliary voltage being higher than that of the voltage to be amplified. In another arrangement the voltage to be amplified is modulated on the auxiliary voltage in a separate device, the auxiliary voltage being given a frequency considerably higher than that of the voltage to be amplified, and the A.C, component of the auxiliary voltage being removed from the output voltage by filters. An output impedance is connected, in series with a D.C. voltage source, between the electrodes 17 and 18 on the photoconductive rod 19. Specification 798,506 is referred to.

Abstract: 595,196. Boring - heads; reamers. OFFEN, A. Nov. 17, 1944, No. 22895. [Class 83 (iii)] A boring-head, reamer, or the like comprises a tubular cutter-bar formed with a transverse recess to receive the cutter or cutters, a clamping-sleeve within the cutter-bar, locking means to engage the inner end of the sleeve and within the sleeve, a longitudinally adjustable setting-rod which at its outer end co-operates with the cutter by a wedging action to adjust it radially of the cutter-bar. A tapered shank 10 has forked arms 11 secured by screws 20 to a split clamping-ring 12, the lower end of which may be tightened on to the enlarged inner end 16 of the cutter-bar 17 by a bolt 14. The screws 20 have split segmental coned heads which may be expanded by means of locking screws 21. A tapered screw 22 projecting into a tapered recess in the ring 12 adjusts and limits the amount of float between the ring 12 and arms 11. The clamping sleeve 25 within the cutter-bar engages at its inner end a clamping nut 24 screwed within the enlarged end of the bar and at its outer end a collar 32 adapted to bear on and clamp the cutters in a recess 23. The extent to which the cutter or cutters project is adjusted by means of a setting rod 26 having a tapered extremity to be inserted between two oppositely extending cutters 27. The upper end of the rod is guided in a bore in a micrometer screw 28 which is adjustable by a milled head 30. The ends of the collar 32 are made torroidal to permit rocking within limits allowed by a pin 33 and an elongated slot 34. In a modified form, the arms 11 are integral with the clamping ring 12 and the collar 32 is omitted, the end of the sleeve 25 acting 'directly on the cutter or cutters. In a further modification, Fig. 6, the arms 11 are replaced by a cranked portion 122, 123, 124 to which an extension 125 of the clamping ring 112 is secured by a screw 126. The degree of float between the shank and cutter bar is controlled by a tapered adjusting-screw 128 taking into a conical recess in the part 125.

The tube opening means includes a pair of rollers 21, 21<SP>1</SP>, the roller 21 being slidably mounted on a bar 18 and connected to the lever 15 by a link 22, the roller 21 being normally urged to an inoperative position by a spring 23. The peripheral surfaces of the rollers 21, 21<SP>1</SP> are coated with an adhesive. In operation, when it is required for the knife 1 to enter between the folded walls 5, 6 of the plastics tube, the lever is moved to cause the blade 13 to cut through both walls, the rollers 21, 21<SP>1</SP> then, due to the adhesive, tending to open the walls as shown in Fig. 1 so that the knife enters therebetween. Instead of the adhesive, suction can be used to obtain the opening effect. The apparatus described can be duplicated on the opposite side of the folded tube so as to slit open both folded longitudinal edges.
