Title: Improvements in or relating to bearings and the assembly thereof
IPC: F16C43/02
Filed: 1966-08-02
Abstract: 1,146,886. Making bearings. FAFNIR BEARING CO. 2 Aug., 1966 [3 Aug., 1965], No. 34603/66. Heading B3A. An outer ring of a spherical bearing is deformed before assembly to facilitate the insertion of a truncated spherical bearing ball 31 by a pusher ball which has spherically shaped opposite end faces 17, 18 and a cross-section between the end faces which has a maximum diameter substantially equal to the entrance diameter of the bore of'the ring so that the pusher ball can be inserted into the ring, rotated to fit with its end faces 17, 18 against the inner surface of the ring and expelled by a force 27 to deform the edge of the ring in two places 28, 29. The outer ring may be an iron base, nickel base or cobalt base alloy or any ductile metal. A larger sized pusher ball may be inserted into the ring an ejected to further deform the ring. The pusher ball may have a conical bevel on its leading face. The truncated bearing ball 31 is then inserted in the ring and the bearing placed on its undeformed face and the deformed areas 28, 29 pressed back into place, Fig. 11 (not shown). The outer ring may be heated or the pusher ball super-cooled to facilitate insertion of the pusher ball in the ring. If the outer ring is hardened by heat treatment after insertion of the bearing ball, the ball is made from heat resistent metal, e.g. tungsten carbide. Detailed heat treatment procedures for the outer rings are described.

Abstract: 1,270,963. Packing articles in bags. MUNKSJO A.B. 15 July, 1969, No. 35471/69. Heading B8C. In an apparatus for packing articles in bags a stack of bags 20, arranged with their openings in the same direction, have extended flaps 4 with lines of weakness 27, 28 to facilitate stripping from the stack 20, the latter being held by a plate 21 having pins 22, 23 which extend through the flaps and into corresponding holes in a support plate 30 which forms part of a table 30, 32, 34 pivoted to a frame 33. After the uppermost bag has been filled with articles 53- 56 the table is swung downwardly by a ram 41, the rapid retardation of the table at the end of its travel causing the breakaway of the filled bag which falls into a collector bin. When the table is raised by the ram 41 an air jet, blown from a nozzle 57, opens the mouth of the uppermost bag which, in the raised position of the table, extends over the free ends of a pair of guideplates 44, which are pivoted to the sides of a filling channel 43 and are subsequently spread apart by rams (46, 47), Fig. 5, not shown, to fully open the bag end. A ram operated pusher 48 urges the articles 53-56 into the bag before the table is again pivoted downwardly and the filled bag is stripped from the stack. The support-plate 30 is urged upwardly by a spring 38 to clamp the flaps 4 against an inturned flange 35 on the table wall 34.

Abstract: 1403014 Compasses METAL MARINE PILOT Inc 31 July 1972 [27 Sept 1971] 35703/72 Heading G1N [Also in Division G3] In a marine autopilot, deviation of the actual heading from a selected heading is sensed by a Hall plate 80 fixed to a course selector dial 52 and co-operating with a permanent magnet 29 fixed to a compass card 28, the Hall plate being fed with a constant D.C. control current and its output voltage being amplified in an integrated circuit operational amplifier Al, offset voltages being cancelled by adjustment of potentiometers 126 and 127. Potentiometer 127 also serves as a means for making small manual course corrections without adjusting the course selector dial. Capacitors 117, 118 differentiate the output of amplifier A1 so that angle and rate signals, in proportions selected by potentiometers 130, 131, are combined and fed to one input of a differential amplifier DA. The actual position of the rudder K2 is sensed by a second Hall plate 160 co-operating with a permanent magnet 161 linked to the rudder. The signal is amplified at A3, offset voltages being cancelled by adjustment of potentiometer 128, and fed to the other input of the differential amplifier DA. If the inputs to DA differ by more than a threshold value adjustably set by a signal on line 144, an output signal appears on line 135 or 136 according to the sense of the error to energize relay RL or RR to operate the rudder motor 141. The threshold value signal at 144 is also automatically adjusted to cause a pulsed approach to null, the setting of a variable resistor 147 determining the level at which the pulse modulation begins and the duration of the pulses. Construction of compass. The Hall plate (not shown in Fig. 2) is mounted on a cylinder 64 fast with the course selector dial 52, electrical connection to the Hall plate being made via brushes 62, slip rings 50a-d and a cable 22 which passes through a radial groove 34a in the compass glass 34. The desired course is set by turning knob 60 to set the course over the lubber line 44. Manual control. A manual control handle (166) Figs. 5 and 6 (not shown) controls the position of a permanent magnet (164) in relation to a fixed Hall plate (180) to derive the control signal, which is fed to the input 133 of differential amplifier DA as in Fig. 4. A switch (204) enables a resistance potentiometer control (170) to be selected instead of the Hall plate.

An automatic continuous process for treating coke oven tar containing water-soluble salts comprises continuously charging streams of coke oven tar and " wash " (as hereinafter defined), at approximately constant rates, into a mixing zone, continuously flowing said mixture of tar and wash at a temperature above 90‹ C. and under superatmospheric pressure through a pressurised settling and decanting zone wherein said mixture separates into an aqueous upper layer and a tarry lower layer, alternately and cyclically withdrawing, at substantially equal rates, material only from the tap and only from the bottom, respectively, of the pressurised settling and decanting zone so that for each cycle (1) the total withdrawal is equal to the total charge during the cycle, and (2) the withdrawal from the bottom is less than the anhydrous tar content of the total charge during the cycle, whereby the material withdrawn from the top comprises aqueous liquor containing water-soluble salts and difficultly decantable tar and the material withdrawn from the bottom comprises product tar relatively free of watersoluble salts and aqueous liquor. " Wash " is defined as an aqueous material consisting of fresh water or a mixture of fresh water with up to 80% by volume of aqueous liquor containing water-soluble salts derived from the process. Preferably the withdrawal from the bottom for each cycle is about 5-20% by volume less than the anhydrous tar content of the total charge during the cycle. Withdrawn aqueous liquor and difficultly decantable tar may be continuously passed through a cooling zone, the cooled aqueous liquor may be continuously passed through an atmospheric pressure and decanting zone in which aqueous liquor containing water-soluble salts separates as an upper layer and difficultly decantable tar as a lower layer. the aqueous liquor may be continuously withdrawn from the top and the difficultly decantable tar from the bottom of the atmospheric settling and decanting zone, and all of the difficultly decantable tar may be continuously recycled to the mixing zone. Preferably the mixture of tar and wash is caused to flow continuously through the pressurised settling and decanting zone at a temperature of about 145-180 C. and under a pressure of about 150-175 p.s.i.g. U.S.A. Specification 2,440,311 is referred to.
