Title: Roller apparatus for automatically aligning moving objects with respect to a predetermined path of travel as the objects pass thereover
IPC: B65G39/071
Filed: 1952-08-06
Abstract: 730,594. Belt gearing. UNITED STATES STEEL CORPORATION. Aug. 6, 1952 [April 17, 1952], No. 19773/52. Class 80 (1). [Also in Groups VIII, XVI and XXX] A roller for automatically centring a moving strip S, such as a driving belt, comprises a shaft 4 which may be driven by an extension 6, the shaft 4 being mounted in bearings 2 and carrying a tubular body 8 of resilient material, e.g. rubber provided with a deep. circumferential central groove 9. Flanges 10, located on the shaft 4 between nuts 12, prevent axial movement of the body 8. In operation, a strip S under tension passes over the body 8, thus causing all surface points on the lines A, B and C, D to move towards axis Y, Y; if the strip is central about the axis Y, Y no lateral movement of the strip will occur. However, if the strip deviates laterally, e.g. to the right as seen in Fig. 1, a greater lateral force will be exerted on the portion of strip above the line C, D, thus causing the strip to move to the left. In a modification, the roll body may have a plurality of additional grooves, these grooves being inclined towards the ends of the roller. The central groove 8 may be undercut to cause movement of the body under less tension than the groove 9. Specification 709,908, [Group XXX], is referred to.

Abstract: 714,482. Load handling appliances. HEUSER, A. Nov. 6, 1951 [Aug. 9, 1950], No. 19812/50. Classes 78 (3) and 78 (4) An industrial truck has a load carriage with stub length forks movable by means of a chain or cable over telescopic and tiltable guides and a retractable load gripping device for holding the load on the forks. A lifting truck, Fig. 1, has a carriage 6 with forks 14 supporting a bale and movable on telescopic and tiltable masts 3 and 4 by a hydraulic cylinder operating through chains, the bale being retained by retractable clamps 16. The carriage has a transverse shaft 21, Fig. 3, supporting a pair of clamps 18 on arms 19, the clamps being rotated to and from gripping position by operating a lever 23 on the mast 3 and connected to cables 24 which rotate a plate 26 attached to the end of the shaft 21. The shaft 21 is raised or lowered by operating two screw threaded rods 28 interconnected by a chain 31 by rotating a crank handle 29. In an alternative form, Fig. 10, a single clamp 18 is connected to the piston rod 42 of a ram and members 49 slide on guides 51 on the frame as the clamp is moved. A control 47 is mounted on the mast 3. The forks 14 are mounted to slide between guide members and each fork has a nut engaging a screwed shaft 33, rotated by a crank handle 36 to vary the distance between the forks. A single fork with a broad base may be used instead of a pair of forks. The forks are arranged to be rather less than half the length of the bale to ensure automatic tilting of the bale at discharge.

Title: Improvements in or relating to magnetisable cores made of sintered oxides and methods of manufacturing such cores
IPC: C04B35/26
Filed: 1956-06-29
Abstract: 803,625. Magnetic compositions. SIEMENS & HALSKE, A. G. June 29, 1956 [June 30, 1955; Sept. 28, 1955; Nov. 15, 1955; March 9, 1956], No. 20167/56. Class 38 (2). [Also in Groups XXXVI and XL (b)] A magnetizable core is made by sintering a mixture of powdered oxides and then slowly cooling it to below 100‹ C. from above the highest Curie temperature of the phases included in the sintered material, the mixture including more than 50 mol. per cent of iron oxide, 0.2-5 mol. per cent of cobalt oxide, and at least one oxide of Ni, Mn, Cu, Mg, Cr, Pb and Zn. The material exhibits a hysteresis loop which is substantially a line enclosing negligible area at low field intensities, Fig. 1a, and is a loop constricted in the middle at a medium range of field intensities, Figs. 1b 1 Two phases have been identified comprising crystallites of grain size 1-3 microns and 10-50 microns respectively. Examples are described where small percentages of CoO are added to mixtures of Fe 2 O 8 ; NiO, MnO, ZnO; Fe 2 O 3 , MgO, MnO, ZnO; Fe 2 O  3 ,MgO,MnO; Fe 2 0 3 , MnO ; Fe 2 0 3 , NiO, ZnO and Fe 2 O 3 , NiO, MnO. The mixture is sintered for 2-3 hours at specified temperatures which are all close to 1250‹ C. and thereafter cooled slowly to room temperature. Various conditions of cooling are specified, e.g. cooling in 40, 24 or 16 hours overall and cooling at different speeds over different parts of the range. The cooling may be carried out in an atmosphere such as air, nitrogen or oxygen, which may be changed during the process. After cooling, the material may be tempered in air for 1 hour at 500‹ or 550‹ C. and again cooled slowly. A lower sintering temperature of 1000-1400‹ C. is chosen if CuO is used. The required characteristics can be expected if the composition has the following constitution, in mol. per cent: 50-80 Fe 2 0 3 , 8-50 Ni, 0-35 Zn, 0-40 Mn and 0.2-5 Co. The cores may be formed by pressing, extruding or moulding before or after sintering. The material may be ground and formed after sintering, and should be tempered and recooled after each mechanical operation. A cable may be loaded by a tape coated or impregnated with the material powdered and mixed with a binder or by a cylinder coated with an insulating or metal layer, Fig. 5 (not shown). Alternatively, a hair-pin shaped conductor may carry two cylinders of the material, Fig. 3 (not shown), or be threaded through two holes in a single cylinder, Fig. 4 (not shown).

Abstract: A method of bonding unvulcanized rubber to other materials-e.g. metal, glass, vulcanite-is characterized by preparing a bonding surface on the rubber by exposure to the action of ultra-violet rays. The rubber may be caused to progress past a mercury-vapour lamp or a series of such lamps at a distance of eighteen inches for a quarter of an hour, or may be exposed to sunlight.  The rubber so treated may be used to bond together materials of a dissimilar nature-e.g. metal and wood and rubber- or a similar nature-e.g. metal and metal.  The rubber is finally subject to pressure and vulcanization. Specification 404,120 is referred to.

Title: Improvements in or relating to an arrangement for supervising and regulating the efficiency of stoking for steam boilers, generators and the like, and for steam installations
IPC: G01L7/00
Filed: 1920-07-09
Abstract: 148,394. Hubert, C. A. June 20, 1918, [Convention date]. Indicating daparture from efficiency relations between quantities measured. - In a steam-boiler furnace installation means are provided for indicating and recording any changes from the normal values of the fluid pressures or pressure differences in different parts, such as in the ash-pit, firebox, chimney flue, boiler, &c., so that the attendant may by operating the dampers, regulating the fuel supply, or clearing the grate restore the normal working condition. In the steam-boiler plant shown in Fig. 1, the chimney draught is communicated through a pipe f to a bell gauge g connected by levers to a recording-drum i and the draught in the fire-box is communicated through a pipe c and bell-gauge d to a pen k. The levers of the bell-gauges are so proportioned that, so long as the relation between the pressures in the chimney and fire-box remain constant, the drum i and pen k will move through the same distance for any changes of pressure in the fire-box and chimney and the pen k will remain on the zero line of the drum. Should the relation between the pressures vary, the pen will move off the zero line and indicate to the attendant that it is necessary to regulate the stoking of the furnace or clear the grate. Fig. 2 shows two differential pressure gauges p, r connected respectively to a recording- drum t and pen s by suitable levers and adapted to record changes in the relation between the difference of pressure in the ash-pit and fire-box and the difference of pressure in the chimney and fire-box. In a modified form of apparatus shown in Fig. 5, a diaphragm pressure gauge 17 connected to a steam-boiler actuates the recording- drum 18 and two bell-gauges 21, 22 under the influence of the draught in the firebox and in the chimney respectively, actuate separate recording pens 20, 19. The steam-pressure gauge is also connected to a plate 26 on which are marked various instructions as to the manner in which the furnace is to be operated. The draught gauges 21, 22 actuate a pointer 25, which indicates the particular operation that is to be carried out, and a plate 27 which covers or uncovers other instructions marked on the plate 26. The recording-drum may be replaced by other indicating devices such as signals.
