Abstract: 942,792. Discharging dustbins into vehicles. L. W. W. EVANS, and GLOVER, WEBB & LIVERSIDGE Ltd. March 14, 1960 [March 12, 1959], No. 8658/59. Heading B8E. A dustbin 9 is raised by arms 21, 22, 23 connected to a power-rotated shaft 27 until it is tipped into a refuse vehicle when rollers 32 engage a cam 20, attached to a bin-holding frame 16 which is pivoted to the arms 21, 22, 23 at 24. Two sets of bin lifting apparatus are provided on the vehicle, there being a pair of arms 21, 22, 23 to each set. The shaft 27 is driven by a semi-rotary hydraulic actuator, but any other form of power may be used. As the bin is tipped the lid 11 of the bin passes through a circular hole in a shutter 34 and into a lidtray 40 where the bin-lid handle 13 is engaged by a bar 45. The shutter 34 is now pushed inwardly by the bin, carrying with it a shutter 31 which pivots about 27. During this movement a cranked arm 41 causes the lid-tray 40 to rotate about its top pivot 47, thereby lifting the bin-lid. As the bin is lowered to the ground the shutters are returned by a spring 38. The bin has a lip 10a, of greater diameter than the lid, which is pressed against and forms a dust seal with a locating ring round the hole in the shutter 34.

Abstract: 314,328. Roots Co., P. H. & F. M., (Assignees, of Owens, R. H.). June 25, 1928, [Convention date]. Movable-abittment type.-In a gas meter or other fluid handling apparatus comprising two intermeshing fluid displacement members, such as rotary lobed impellers 20 of the " Roots Blower " type, adapted to be operated in timed relationship, a timing gear 24 keyed to one of the parallel shafts 21, 22 supporting the fluid displacement members meshes with a timing gear 33 which is adjustably clamped by bolts 29 to a timing gear 32 keyed to the other parallel shaft and the timing gear 32 meshes with a timing gear 26 similarly clamped to the timing gear 24. The slots 30 in the gears 26, 33 through which the bolts 29 pass are of sufficient size to allow of a rotational adjustment of about one tooth width at the gear periphery thereby enabling the gears to be set so as to run quietly and to eliminate lost motion between the shafts 21, 22. The timing gears are arranged in an oil chamber 43 formed by a partition wall 41 extending from the end-plate 35 of the impeller casing. The shafts 21, 22 are fitted with slinger rings 45 where they pass through apertures 44 in the wall 41 and the apertures 44 may be fitted with cover plates 50. Lubricant is supplied through removable plug 50<1> in the cover plate 49 to the chamber 43 which communicates through a small passage 42 in the wall 41 with a chamber 40 in the lower portion of the end-plate 35. Excess lubricant supplied to the ball bearings 56 of the shafts 21, 22 is slung off by collars 55 into a chamber 38 from which it passes to an excess lubricant chamber 39 communicating with the chamber 40. As the lubricant in the chamber 40 is not agitated by the timing gears impurities will settle and may be drawn off through a drain cock 47. When the lubricant is liable to become mixed with light gravity gas oil the communication 42 between the chamber 43, 40 may be omitted and the light oil may be drawn off through a trapped pipe extending to the surface of the lubricant in the chamber 40. At their other ends the shafts 21, 22 are fitted with slinger rings 63 throwing off excess oil from the bearings 67 into a chamber 61 communicating with a chamber 62 fitted with a drain cock 65. The bearings cups are fitted with interchangeable bearing caps and an instrument drive 75 and hand crank starting connection 76 are provided at the shaft ends. The bed plate 13 on which the impeller casing rests is formed with a recessed flange 16 to receive dripping from the meter. Specifications 275,186 and 325,780 are referred to.

Title: Quantum resonance method and apparatus
IPC: G01R33/46
Filed: 1963-03-07
Abstract: 976,427. Quantum resonance apparatus. VARIAN ASSOCIATES. March 7, 1963 [March 9, 1962], No. 9117/63. Heading G1N. In quantum resonance apparatus a first set of particles is excited at one frequency, a second set of particles is excited by a second frequency modulated by a third, preferably audio, frequency and the resonance of those members of the second set of particles coupled fo members of the first set is measured by detecting the modulation of the first frequency produced by the coupling. The invention is described with particular reference to the investigation of the resonance of the C<SP>13</SP> isotope coupled to a proton this resonance normally being masked by the resonance of protons coupled to non-gyromagnetic isotopes of carbon. As shown in Fig. 1 an oscillator 5 is used to modulate a R. F. transmitter 4 which is used to resonante the C<SP>13</SP> isotopes and a R. F. transmitter 3 is used to resonate the protons. The modulation of the proton resonance produced by coupling to C<SP>13</SP> isotopes is detected by R. F. mixer 7 anda phone detector 9 drives a recorder 11 which is also driven by a sweep generator with period 1-10 minutes which sweeps the resonance through a bias coil 10<SP>1</SP> on the D.C. bias magnet 2. The embodiment of Fig. 2 is used to investigate the chemically shifted lines of C<SP>13</SP> by means of a further R.F. transmitter 12 coupled to the particles and driven by a sweep generator 13 through a predetermined frequency range. Means for stabilising the proton resonance are described with reference to Figs. 4 and 5, (not shown). In the former a further magnet bias coil 14 is energized by a second phase detector 14 which has an output varying as the frequency moves from resonance. Thus the output can be used to maintain resonance. In a further arrangement Fig. 5 (not shown) the detected sideband frequency is fed back to modulate the R.F. transmitter in a self sustaining arrangement and the local oscillator is dispensed with. The modulator 4<SP>1</SP> may produce either frequency or amplitude modulation and the probe may be of the crossed coil induction type or of the single coil absorption type. The sinsitivity at large modulation frequencies is improved by using side-band resonance techniques. Instead of using bias fields the frequencies of the transmitters may be adjusted. Also one generator may be used supplying the desired R.F. frequencies through synthesis networks. The apparatus may also be used where the two sets of particles are different isotopes of the same element or even chemically shifted group of the same isotope.

Title: Formation of nuts
IPC: B23K15/00
Filed: 1972-03-01
Abstract: 1374915 Making lock nuts; welding by fusion  M HATTAN W P GREEN and A H GOERING 1 March 1972 [8 March 1971] 9435/72 Headings B3A and B3R [Also in Division F2] A nut 10 is formed by locating within a casing 12 a helical metal coil 13 shaped internally to form a screw thread and being in a workhardened condition, and welding the radially outer portion of the coil to the casing 12 by locally heating said outer portion to a temperature locally adversely affecting the workhardened condition of the coil outer portion, while maintaining the radially inner portion of the coil at a temperature low enough to avoid destroying said work-hardened condition. The coil 13 is formed by drawing a circular wire 20 through a forming machine 21 to produce the cross-section shown and to work-harden the wire, and forcing the wire against a die 23, the wire being sheared by a cutter 24 after 5“ turns have been formed. The coil 13 and an end bush 14 are placed in the casing 12 and the assembly clamped between plates 41, 42, a packing washer 53 and a spring washer 55 under the plate 41 ensuring that the casing 12 and coil 13 are pressed firmly against the bush 14. A copper or aluminium mandrel 45 is screwed into the coil 13 to provide a heat sink during welding. Laser or electron beam welding, using a gun 56, heats a tapering zone (shown by dotted lines in Fig. 1) to weld the coil and the bush to the casing 12, and to weld adjacent turns of the coil 13 together at their radially outer portions. The upper coil 13<SP>1</SP> is not welded. After welding the nut is removed from the tool 40 and is deformed radially inwardly at two diametrically opposite points adjacent its upper surface 18 by forging dies 59 to make the nut self-locking (Fig. 6). Finally the nut is heat treated at a temperature high enough to harden the casing 12, coil 13, and bush 14 without destroying the work-hardening of the thread portion of the coil. The casing may be of martenitic stainless steel and the coil may be of semi-austenitic stainless steel, both parts, except for the welded periphery of the coil, will in the completed nut be in heat hardened martensitic condition.
