Title: Bearing assembly
IPC: B02C7/14
Filed: 1971-10-20
Abstract: 1373372 Fluid-pressure servomotor systems DEFIBRATOR AB 20 Oct 1971 [26 Oct 1970] 48779/71 Heading G3P [Also in Divisions B2 and F2] A radial and axial thrust bearing assembly 14 Fig. 1 comprises two halves, each consisting of an inner ring, an outer ring 40, 48 Fig.3, and rolling elements 44, 50, and a casing element 42 positioned between the outer rings and housing at least one pressure member 58 to produce axial pressure against the outer rings to eliminate bearing play in the two halves, the pressure member being actuated by a pressure fluid so that in operation the said axial pressure is reduced in response to an increase in axial pressure imposed on the bearing and vice versa. The pressure member comprises an annular system 58, which may contain axial bores 68 each containing a spring 70. Pressure fluid is supplied to a chamber AS. The bearing assembly 14 supports one end of a shaft 12 in a grinding assembly. Before material is fed to the grinding discs 18, 20, fluid supplied to the chamber AS from a valve 78 takes up play in the bearing assembly. Fluid is also supplied to chambers A, B in a fluid servomotor 28 at such pressures that the shaft 12 is kept in equilibrium. As grinding pressure increases, axial pressure on the bearing assembly and on the central piston of the servomotor causes movement of the shaft 80 in the valve 78 via a member X to which the piston of the servomotor is attached. This causes pressure in the chamber B to be increased and the pressure in the chambers A and AS to be decreased thereby reducing the pressure taking up bearing play. The initial position of the shaft 80 in the control valve is adjusted by means of a screw 126.

Title: Improvements in or relating to Sterilizing Apparatus
Inventor: REESBY CYRIL FRANK
IPC: A61L2/24
Filed: 1966-11-01
Abstract: 1,163,917. Temperature indicators. HONEYWELL Ltd. Dec. 21, 1967 [Nov. 1, 1966], No. 48909/66. Heading G1D. Sterilizing apparatus comprises a sterilizer having an enclosure 1 to contain articles to be sterilized, one or more sensor units disposed inside the article or articles to be sterilized, the sensor unit 2 each comprising a radiation transmitter e. g. of radio frequency, a temperature sensitive switch arranged to alter the operation of the transmitter on reaching a predetermined temperature, e.g. by switching it off, changing its frequency or by making it "squegg", and a power supply for the transmitter; a radiation pick-up 3 in the enclosure 1 connected to an amplifier 5 for lighting or extinguishing a lamp 7 and/or operating a timer 7a connected to a relay 8 controlling operation of the sterilizer. In use the article or articles containing the sensor units are placed in the enclosure 1, and if the transmitters are normally on at this stage this may be used to start the action of the sterilizer since the pick-up 3 will detect the transmitter output. When the temperature in the article or articles has risen to the desired temperature, the thermal switch e.g. of mercury in glass or bi-metallic type may be used to switch off the transmitter and the lamp 7 will be extinguished. This also starts the timer 7 to allow heat to be further applied to the enclosure 1 for a desired period of time. Where the transmitter frequency changes the amplifier 5 is tuned to one of the transmitter frequencies and where the transmitter is made to "squegg" the amplifier 5 is sensitive only to changes in amplitude of the transmitter output. Different articles require different sterilization times and this can be provided for by providing different articles with transmitters having different frequencies. In this case a number of tuned amplifiers are provided in parallel each connected to operate appropriate control circuits when the correct frequency signal is detected. The transmitters may be battery powered or fed from an inductance receiving electomagnetic radiation from outside the unit, a rectifier being coupled to the inductance.

If the silvex is also contaminated with 2,4,5-T, the 2,4,5-T can also be removed by precipitating it in the form of an alkali metal salt by treatment in an aqueous medium with an alkali metal hydroxide at a temperature in the range in which the alkali metal salt of 2,4,5-T is substantially insoluble and the alkali metal salt is substantially soluble. This treatment is normally carried out prior to the liquid-liquid extraction when the silvex is converted to an alkali metal salt, and subsequent to the extraction when the silvex is converted to an amine salt. The silvex may be recovered from the raffinate by distillation of any co-dissolved non-polar solvent therefrom together with acetonitrile, if present, and then reacting the silvex salt with a mineral acid to precipitate the silvex.

Abstract: 1520671 Heart pacemakers MEDTRONIC INC 8 Dec 1975 [9 Dec 1974] 50268/75 Heading A5R [Also in Division H3] A synchronous heart pacemaker incorporates an upper limit for the rate of stimulation, applicable where the detected natural beat rate exceeds the limit. Pulse generator 10 (Fig. 2) includes an oscillator 12 and a rate limit circuit 50 which sets a minimum 500 ms pulse spacing (120 per minute). if the oscilllator is triggered too rapidly (as if a circuit element is defective). Normally-conductive transistor Q12 (Fig. 3b) is biased off after each output pulse by charge on capacitor C15 until the capacitor has discharged over 500 ms, preventing transistors Q9, Q11, Q13 and Q14 being turned on to discharge output capacitor C13. In the absence or detected natural beats the oscillator is free-running (asynchronous) with a period (1000 ms) determined by its RC-circuit C11 and R14, but output pulses are also triggered on demand (synchronously). A suitable interval (100 ms) after detection of a P- wave. Detection of a P-wave or an R-wave at 18, 14 Fig. 2 causes inhibit circuits 58, 34 to render the respective detectors 54, 25 refractory for a period (150 ms, 300 ms). Each detected P-wave sets a bistable memory 66 and if the setting is not cleared within the 100ms interval by detection of an R- wave, delay circuit 70 triggers the oscillator 12. Each oscillator output pulse resets the oscillator activates inhibiting circuits 50, 58, 34 and clears the memory 66. In the rate-limited mode of the invention, a natural P-wave will on occasion be received while the P-wave detector is refractory for 150 ms following an R-wave, and will not therefore give rise to an output pulse. The R-wave spacing will be about 650 ms, rather than 500 ms, at this point.
