Title: Improvements in or relating to hydraulically operated lifting apparatus
Inventor: BRACEWELL ALLAN
IPC: B66F9/04
Filed: 1957-05-01
Abstract: 899,422. Platform elevators on vehicles. BRACEWELL (HYDRAULICS) Ltd., ALLAN. Aug. 1, 1958 [May 1, 1957; May 6, 1957], Nos. 13883/57 and 14343/57. Classes 78 (3) and 78 (4). In a guided-platform hoist, movement of the platform is effected by an hydraulic ram which is controlled by means responsive to the load on the platform, and the upper limit of travel of the platform is adjustable to any position within a predetermined range. In the embodiment shown in Fig. 1, on placing a load on a platform 10, the platform moves down it, relative to the piston 20 of an hydraulic lifting ram 22 against the action of a spring 16 and an arm 42 engages an abutment 40 on a control rod 30 to move the rod down, thereby operating a valve 52 through a lever 32 to allow fluid to pass to the ram 22. At the upper limit of travel of the platform, the arm 42 engages an adjustable abutment 44 on the control rod 30 which operates the valve 52 to allow fluid to pass back to the reservoir. On removing the load, the platform rises relative to piston 20 under the action of spring 16 and moves the control rod to bring the valve 52 into a third position to allow the platform to descend. In a second embodiment, Fig. 3, on placing a load on a platform 142, mounted on a plunger 140, the platform descends against the action of a spring 143 and the plunger 140 closes channels 138 thereby preventing hydraulic  fluid from passing through the hollow piston 118 of a lifting ram 110 to the reservoir 112 and so causing the piston, together with the plunger 140 and platform, to rise. At the upper limit of travel, rubber blocks 158, on a striker ring 152 adjustably mounted on rods 148 which move with the piston, engage stops 150 and build-up of pressure under the piston 118 operates an overload release valve 166. On removing the load, the platform 142 and plunger 140 rise under the action of spring 143 allowing fluid to pass through the cylinder 118 and channels 138 and 160 to the reservoir, thereby allowing the piston and platform to descend.

Filed: 1971-05-10
Abstract: 1343493 Corrugated container-board ALTON BOX BOARD CO 10 May 1971 [20 May 1970] 13950/71 Heading B5N Rigid-when-wet corrugated container-board is prepared from a preformed web of medium and at least one preformed web of liner by printing upon the reverse face of the or each liner web discretely metered increments of a curable thermosetting resin, especially a phenol-formaldehyde resin, entrained in a vaporizable liquid vehicle (usually water) and immediately vaporizing the vehicle from the web by heating at a temperature and for a time less than that required to cure the resin. The container-board may comprise three plies 5, 6 and 7 to which the resin solution or emulsion is applied by applicators 1, 2 and 3, and 4, respectively, comprising gravure rollers of the "quad", "pyramid" or, especially, the "tri-helicoid" type. The partially impregnated webs are then passed around heated rollers 8, 9 and 10 to remove the water vehicle and as much other paper-entrained water as is desirable without curing the resin. The medium web is passed to a corrugator 11, adhesive is applied to the crowns of the corrugations by means of applicator 12 and the corrugated web laminated to liner 5 by means of a back-up roller 13. The adhesive may be cornstarch or a cornstarch-resorcinol mixture and may molecularly bond with the phenolic impregnant of the webs under curing conditions. The second liner 7 is then laminated to the medium liner composite by means of adhesive applied at 14 to the exposed crowns of the corrugations and the laminate subsequently cut-off, scored and/or slit to provide container blanks such as the one shown in Fig. 2. The blank may be converted into a "flat folded" or "knocked-down" container as in Fig. 3 by completing the "manufacturer's joint" which involves adhering or stitching of the flap 25 to the remote edge of end panel 21. Either the blank or the knocked-down container may be subjected to heat to complete the cure of the resin impregnant, usually by passage on an endless conveyer through a tunnel oven (Fig. 5, not shown).

Title: Process for the complete elimination of the flourescence of mineral oils
Inventor: HOFLING WILHELM
IPC: C10G71/00
Filed: 1959-04-27
Abstract: Fluorescence is completely eliminated from mineral oils by a process which consists in prepurifying the oil as far as possible by means of excess sulphuric acid or oleum and then blowing a gas which is inert to the oil through the prepurified oil at a temperature not in excess of 104 DEG C. and such that no oxidation of the hydrocarbons occurs, settling out precipitated impurities, and removing remaining impurities from the oil by a bleaching earth treatment which includes filtration.  Inert gases mentioned are nitrogen and carbon dioxide. In the example the oil is a refined machine oil (5 to 6,5 E/50 DEG C.;S.G. 0,89 to 0,93), the acid treatment is carried out in two stages, first a double treatment with 95 to 96% sulphuric acid and then a double treatment with oelum 86%SO3), and the earth treatment is effected by stirring the oil with 3% of bleaching earth, settling, and filtering through a vacuum filter containing a 4 to 5 cm. thick layer of bleaching earth.

Elements moving always in one plane, rotating; optical-projection apparatus, applications of. -In optical-projection apparatus in which the transparencies are mounted on a disc rotated step-bystep to bring them in turn between the lantern lenses, several rows of apertures to receive the transparencies are provided in the disc, some of the holes of rectangular form being, if required, disposed tangentially to ancommodate additional lanterns. The device is preferably constructed as a clock column, and one or two discs may be provided in conjunction with lanterns 60 and reflectors 70, which will throw one or a pair of pictures on one or more sides 56 of the column, as shown in Fig. 14. The clock may bear advertisements, and be illuminated by a lamp which is extinguished during a change of pictures. The disc 20 is of metal and may be angularly adjusted on its spindle by slot and bolt engagement. Two or more peripherally arranged shrouded idle wheels steady the disc 20. The transparencies 26. Fig. 10, are mounted in an upright or inverted position on the disc 20 according to the position of the lantern for that particular row, and are fixed by wing bolts 27 provided with cushioning springs 28 within washers, or by claw springs. The mechanism for imparting intermittent motion to the disc 20 comprises a solenoid or electromagnet 35, Fig. 1, which is energized at intervals by a clock train or other means. The armature 36 is mounted on a bell crank 37 the other arm of which is connected by a link 38 to arms 39 pivoted at 40. The arms 39 push a pin 42 projecting on both sides from a pulley 34 round which passes a cord supporting a weight 32. A link 44 pivoted on the pin 42 operates a locking pawl 45 engaging a toothed wheel 51 fixed to the disc spindle 23. A pawl 50 prevents backward movement of the wheel 51 and disc 20. A spring-pressed pawl 47 on the pulley 34 engages a toothed wheel 49 also fixed to the spindle 23. In operation, carrent passing through the magnet 35 pushes the pin 42 to the left, thus raising the weight 32 and releasing the pawl 45, the pawl 47 riding back over its teeth owing to the wheel 51 being held by the pawl 50. On cutting off the current the weight 32 turns the pulley 34, the wheel 49 and the disc 20 through one picture space.

Filed: 1927-05-27
Abstract: 295,772. British Thomson-Houston Co., Ltd., Peacock, J. V., and Nixon, L. R. May 27, 1927. Exciting - motor generators.-An electric generator driven by a machine having a falling speed-load characteristic, e.g. an induction motor, is designed to give substantially constant current over a wide range of voltage from zero and has an exciter mechanically driven therewith, the field of the exciter being varied in accordance with variations in the generator load. In Fig. 2, the generator 1 has a shunt field winding 2, a winding 4 fed from the exciter 5 and a differential series winding 3. The exciter has a shunt field winding 6, a series winding 7 and a winding 8 connected across the terminals of the generator 1. The windings 6, 7, 8 on the exciter all assist, and since the load on the generator is proportional to the voltage, decrease of speed due to increased load results in a greater current flow in the exciter field winding 8. The increase of ampere turns may be made proportional to the drop in speed of the main generator so that the exciter voltage is maintained constant or this voltage may be caused to increase. In a modification, the exciter winding 8 is connected in series with the generator shunt field winding 2. Fig. 4 shows another modification in which the additional winding of the exciter is dispensed with, but the circuit of the shunt winding 6 is extended to include a portion of a resistance 9 in series with the generator shunt field winding 2. If the driving machine be a continuous current motor, the exciter winding 8 may be connected so as to carry the whole or part of the motor current. Specification 281,009 is referred to.
