Title: Anti-friction bearings
IPC: F16C43/08
Filed: 1958-12-24
Abstract: 849,518. Assembling bearings; contracting- rings. CHANNING CORPORATION. Dec. 24, 1958 [Dec. 31, 1957], No. 41681/58. Classes 83 (2) and 83 (4). Method of making anti-friction bearings comprises loosely assembling the parts of each such bearing with a complement of rolling elements, e.g. balls, interposed between a circuinferentially-grooved inner race component and an internally-grooved outer race component, rotating one of the race components of the assemblage and at the same time forcing the assemblage through a tapering hole in a die to circumferentially contract the outer component of the bearing about the rolling elements and cause the raceways of both components to conform smoothly and accurately to the rolling elements. An annular inner race component 1, formed with an axial bore 3, eccentrically offset coned counterbore 4 and peripheral groove 2, and an annular outer race component 5. formed with an internal groove 6 and having the diameter of its opening larger at the upper end 7 than the lower, are assembled with balls 8 therebetween and the assembly placed in the upper, wider end of a tapered hole 37 of a die 32. The die 32 is then raised so that a spherical head 25 of a drive element 23 enters the bore 3 and an off-centre coned part 26 of the element 23 engages the counterbore 4. During further rise of the die 32 a fixed plunger sleeve 13 pushes the outer race 5, and the element 23 the inner race 1, through the tapered hole 37, the inner race 1 being rotated by the element 23 itself rotated by a pulley 21. The outer race 5 is thus contracted and the groove 6 therein smoothed. In a modification the counterbore in the inner race 1 is formed with two conical lobes 4a, Fig. 10, to co-operate with a similarly-shaped drive element 23. The axis of the element 23 may be slightly eccentric to its rotary axis so that the inner race 1 is gyrated slightly as well as being rotated. The completed bearing may be heattreated. Roller bearings may be similarly formed.

Abstract: 1,167,143. Routing of road vehicles. RICHARD COSTAIN (CIVIL ENG.) Ltd. 10 Oct., 1966 [13 Oct., 1965], No. 43514/65. Heading G4Q. In an arrangement for routing coal or rockcarrying dumpers 9, 10, respectively, to coal or rock excavators 2, 3, respectively, in an open cast coal mine 1, the function of each vehicle is determined at entry-exit points 4 and 5 and fed to a control unit which then indicates to the dumper driver the number of the excavation site to which he has to proceed, the site chosen by the control unit being the one at which minimum waiting time will be encountered. At each point 4 or 5 a photo-electric detector unit 12 or 13 including four cells is provided, the two upper cells co-operating with lamps 11b on coal dumpers and the two lower cells cooperating with lower disposed lamps 11a on rock dumpers. If a dumper is used for its designed purpose its upper lamp is lit but if it is used for a different purpose, i.e. a rock dumper allocated to carry coal, its lower lamp is lit. Signals from the detectors pass to a control unit 15 including a number of sub-units 16, each of which is allocated by means of a switch 17 to a particular excavator. The type (rock or coal) of excavator is set by switch 18 and the sub-unit is provided with a timer unit 19 including pairs of switches 20a, 20b or 21a, 21b which can be set to the estimated time for a dumper of a particular type to the loaded- The timer clock in each sub-unit is run down to zero by a pulse received from a synchronous unit every 15 seconds. On receipt of a dumpertype signal the sub-units are scanned to determine the unit with the minimum time stored by its clock, the number of the excavator allocated to the selected sub-unit is then displayed to the dumper driver by display units 26 or 27 and the time set by the switches 20 or 21 is added to the timer clock.

Abstract: 1,077,892. Circuits employing magnetic storage elements. SPERRY RAND CORPORATION. Oct. 26, 1964 [Nov. 6, 1963], No. 43604/64. Heading H3B. A transient signal (e.g. from a nuclear weapon burst) is sampled by passing it through parallel arranged different delays 46-52 and flux-gating the respective different elemental sample portions into respective magnetic memory elements 54-60 by a strobe pulse generator 44 which provides a strobe pulse at a time after the wave front of the transient signal equal to the delay time of the longest delay. The transient signal is from a constant current source and is insufficient by itself to switch the memory elements and the strobe pulse, also from a constant current source, is of magnitude sufficient to switch the memory element but of duration too short for complete switching whereby both together can partially switch each memory element to store a flux representative of the magnitude of the respective elemental sample portion of the transient signal. Each memory element comprises two magnetic cores which may be single aperture cores (110, 112), Fig. 6 (not shown), or double aperture transfluxors (140, 142), Fig. 8 (not shown), for non-destructive read out. One core of each element (110, 140) stores flux due to the combined strobe pulse and elemental sample portion whereas the other core (112, 142) stores only flux due to the strobe pulse. The output winding (116, 146) is wound in opposite senses round the respective cones whereby the output of the memory element during read-out is proportional to the elemental sample portion.

INDUSTRIELLE ET COMMERCIALE DES AUTOMOBILES PEUGEOT. 3 Oct., 1967 [9 Nov., 1966], No. 45052/67. Heading H1P. The permanent magnet armature 9 for a tachometric alternator is partially demagnetized by feeding to the stator windings 8 a source of alternating current of increasing intensity, the armature being driven at such a constant speed by motor 10 that the frequency of the alternator current is different from the source of A.C. The intensity of the source of A.C. from 3 is varied using a motorized autotransformer 4 or a saturable inductance. Periodically the output voltage of the alternator is measured automatically by device 11 which switches contact 6 to a voltage meter 12 and controls the motion of autotransformer 4. A number of alternators having identical voltage outputs may be made in this way. If the alternator is used for controlling gear changes in an automobile, the stator poles are positioned to correspond to the maximum engine load and the speed of motor 10 corresponds to that selected for a gear change.

Abstract: 1,088,321. Bearings, lubricating. SHEFFIELD CORPORATION. Nov. 10, 1964 [Nov. 29, 1963], No. 45790/64. Heading F2A. A fluid bearing comprises sensing means responsive to the size of the distance between opposed bearing surfaces and which regulates control means controlling the flow of fluid supplied between the bearing surfaces. In Fig. 2 air from supply line 21 and pressure regulator 22 passes through line 28 and pressure relay 27, which is provided with valve 32, to outlet 35 and serves to separate the bearing surfaces 13, 16. Air also passes through restrictor 23 and line 25 to orifice 26, the back pressure generated in the line 25 resulting in a deflection of diaphragm 31 of relay 27. Thus a decrease in the distance between the bearing surfaces 13, 16 causes an increase in back pressure which deflects diaphragm 31 and further opens valve 32, and increases the flow of air to separate the surfaces, and vice versa. Constant spacing between the surfaces is thus maintained. Separate bearing zones are provided (Fig. 3, not shown) each bounded by air channels in surface 16 leading to atmosphere, and comprising an area with outlets and one or more sensing orifices. The fluid supply to each zone is controlled independently. The embodiment relates to supporting a tailstock of a grinding machine.

Abstract: 1277973 Semi-conductor devices SONY CORP 17 Sept 1969 [18 Sept 1968 (2)] 45864/69 Heading H1K A vapour-grown polycrystalline semi-conductor region contains a pn junction. In the manufacture of discrete diodes a polycrystalline ntype Si layer (103), Fig. 1 (not shown), comprising vertically aligned acicular polycrystals is grown from SiCl 4  and AsCl 3  vapours on to a low temperature vapour deposited polycrystalline Si layer (102) on an n+ type Si single crystal substrate (101). B is then diffused into the layer (103) through an oxide or nitride mask (104) to form a pn junction (106) in the layer (103). The B diffusion may penetrate entirely through the layer (103) to reach the substrate (101). Instead of using the vapour deposited polycrystalline Si layer (102) as the surface on which the polycrystalline layer (103) is grown, a SiO 2  layer may be deposited or the substrate surface may be subjected to sand-blasting or scratching. Fig. 6H shows part of an integrated logical NAND circuit including three parallel-connected diodes formed in a vapour deposited ntype polycrystalline Si region 304a D . The three diodes have a common B-diffused p-type anode region and separate P-diffused n-type cathode regions K 1 , K 2 , K 3 . The polycrystalline region 304a D  is deposited on a p-type Ga-doped Si substrate 301 together with polycrystalline device isolation regions and monocrystalline regions in which further circuit elements such as resistor R and transistor E, B, C are formed. The various polycrystalline regions occur due to the presence of " seeding areas " on the surface of the substrate 301. Al electrodes are provided for each of the circuit elements. In a further embodiment of the invention p-type polycrystalline islands (504), Fig. 7 (not shown), are produced on a contoured surface of an n-type single crystal substrate (501), a polycrystalline support wafer (506) is provided over the surface containing the islands, and the major part of the original substrate (501) is removed to leave a mosaic of monocrystalline and polycrystalline regions in which circuit elements are formed. In modified arrangements the original substrate may be of polycrystalline semi-conductor, mica, ceramic or sapphire. Other semi-conductor materials referred to are Ge and intermetallic compounds.
