Abstract: 1,225,925. Refractometers. HERAEUSCHRIST G.m.b.H. Aug.20, 1969 [Aug. 22, 1968], No. 41618/ 69. Heading G2J. In a method of optically measuring and recording sedimentation in a high-speed centrifuge with a measuring cell arranged in its rotor so as to pass through an optical beam having one or more gas discharge lamps as light source, the lamp or lamps is/are ignited for a period which up to the maximum speed of the rotor, is not substantially longer than the time required for the measuring cell to pass through the optical beam. At maximum speed the ignition period may be less than the period the cell takes to pass through the beam and the beginnings of the two periods are synchronized so that the lamp always lights up when the cell passes through the optical beam. As shown a rotor 2 in a chamber 9 is driven by a motor 20 and as it rotates each measuring cell 4a, 4b, 4c (containing in suspension the substance whose sedimentation is to be examined) passes through an optical beam 7, sedimentation being recorded by a device 8 (e.g. a photographic plate) using light from a gas discharge lamp 1. Capacitative counterelectrodes 3a, 3b, 3c on the rotor co-operate with a pick-off 5 to produce a corresponding number of signals in each rotation. The signals are counted by a monitor 6 which produces control pulses for the lamp 1. A pre-selector device 10 may be set to influence the monitor 6 to release a control pulse to ignite the lamp only when a particular cell e.g. 4a passes the beam 7 so that the others pass in the dark. The tests may be varied by using a number of lamps and illuminating a cell with radiation of different wave lengths in any desired sequence by providing monochromatic devices or filters, also the wave length can be adjusted to that for maximum absorption of the substance being examined and a number of individual substances in a mixture can be examined. The velocity of the Schlieren image may be measured or the refractive index gradient according to Toepler may be recorded.

Abstract: 1,239,586. Measuring fluid-flow. BADGER METER MFG CO. Nov.15, 1968 [April 18, 1968], No.54255/68. Heading G1N. [Also in Division G4] The invention relates to nuclear magnetic resonance flowmeters comprising a tagging station and a detection station. Paramagnetic fluid-flowing through a conduit is subjected first to a magnetizing field M at right angles to the direction of flow and then to an r.f. field H 1  crossed with a D. C. field Ho anti-parallel to M, the Ho field having a gradually increasing intensity at its upsteam edge which is within the H 1  field to cause adiabatic rotation of the magnetization of the fluid into a direction at 45 degrees to the H 1  field, the Ho and H 1  fields extending over the length of conduit in which tagging and detection occur. At the tagging station, a coil 20 is pulsed to generate a high intensity field parallel to Ho and of short duration to cause a non-adiabatic rotation of the magnetization of a tagged bolus through about 90 degrees leading to a rapid dissipation of the magnetization. At the detection station, the Ho field is modulated at an audio frequency and a receiver coil 22 is connected to circuitry for detecting the N. M. R. signal produced by untagged boluses at the sum or difference of the audio and r.f. frequencies. On detection of a tagged bolus, a new tagging pulse is generated, the frequency of a voltage controlled oscillator 56 being adjusted to keep the tagging pulses in quadrature with the detected signal. A counter 65 registers total flow.

Abstract: 1,250,133. Grinding. C. W. GEHRING. 16 April, 1970 [17 April, 1969], No. 18099/70. Heading B3D.  An hydraulic feeding device for controlling the feeding movement of a honing tool H comprises an hydraulic piston and cylinder system which is non-rotatably connected to the honing tool and is designed as a rotary valve operable in response to frictional engagement of the tool with the workpiece to at least partially close a control bore to stop or nearly stop a fast feed of the stones H 1 , H 2  of the tool and permit fine feeding of the stones. The body of the honing tool is connected to the cylinder 2 of the system and the cones K 1 , K 2  for adjusting the stones H 1 , H 2  are connected to the rod K which extends through a stuffing box S and is connected to the piston 1. The cylinder is rotatable by an extent limited by pins 8 engaging grooves 10 in a housing 3 and has transverse bores 13, 21 leading from cylinder space 35 and co-operating with longitudinal bores 15, 23 in the housing connected by a distributer 20 to conduits 34, 36. The space 27 above the piston is connected by a bore 24 to a conduit 33. Conduits 33, 34 are connected by a reversing valve 32 to a pump P and tank T, and conduit 36 is connected to a throttle valve 37, an open/ closed valve 38 and tank P. In operation, the valve 38 is initially closed and valve 32 directs fluid through conduit 33 to lower position 1 so that the cones rapidly expand the hone, exhaust fluid passing through bores 13, 15 to conduit 34. When the honing stones frictionally engage the workpiece, the resistance causes a rotation of the cylinder 2 relative to the housing to an extent determined by the pins 8 and grooves so that the bore 13 is disconnected from bore 14 and the rapid expansion stopped. The valve 38 may then be operated continuously or intermittently to connect the conduit 36 through the throttle valve 36 to the tank to effect the fine feed.

[Also in Division F1] In an arrangement for pumping a liquid or a gas whose temperature differs substantially from the ambient temperature, a heat barrier section formed by a casing 2 surrounding the driving shaft 3 is arranged between the pump 1 and a seal 18 to maintain the latter at a temperature which is not too hot or too cold for effective operation thereof. The barrier section is cooled or heated by a current of air delivered over the casing 2 by a fan 30 mounted on the shaft 3. The casing 2 has fins 13 thereon. The fluid in the casing 2 is either the fluid being pumped or another fluid. A seal, e.g. a gland packing or a labyrinth seal, may be provided between the pump and barrier section provided some communication is established therebetween. A duct 27 can be used for purging air from the barrier section on start-up, for periodically purging dirty liquid from the barrier section, or for continuously passing purging liquid into the barrier section. A coil 28 ensures that the purging liquid temperature approaches that of the ambient before the liquid reaches the region of the seal 18. A pipe 25 delivers leakage to a tray 26 for checking the amount of leakage through the seal 18. Thermocouple probes 31 indicate the temperatures at the barrier section and seal 18.

In mounting a car body on the bolster of a railway bogie, wherein a centre post 43, rigid with the underframe U, preferably has resilient pad connecting devices 49, allowing lost pivotal and transverse motion between the post and the bolster, but transmitting longitudinal motion, substantially without play, therebetween, additional transverse stiffness is provided in lateral springs, arranged between the underframe and the bolster, by making parts of the springs non-yieldable to transverse body movement. The lateral springs may be wholly pneumatic (Fig. 5, not shown) or partly pneumatic and partly constructed of a sandwich of elastomeric pads 37 and metal plates 39. Parts 37, 39 are made non-yieldable transversely by bridging them with inextensible links 57. Pneumatic parts 31, 33, 35, which are connected to a source of compressed air, are transversely yieldable, but are restrained against yielding longitudinally by links 36. Thus longitudinal yielding due to relative swivelling between the bolster and car body results in the parts 37 and 39, alone, being strained in shear. Links (77, Fig. 5, not shown) bridge convolutions (70, 71) of triple convolution flexible-wall pneumatic springs, to achieve the same effect. Reference has been directed by the Comptroller to Specifications 863,869 and 1,097,482.
