Title: Improvements in clutches and the like
IPC: F16D43/10
Filed: 1930-04-03
Abstract: 339,581. Herve, A. April,8, 1929, [Convention date]. No Patent granted (Sealing fee not paid). Clutches, friction and claw. - A clutch or like device comprises a driving-shaft 2 and a driven shaft 5 journaled at 6 in an extension 1 of the shaft 2, one or more coupling discs 8 locked to the driving shaft 2, so as to rotate therewith, by means of bolts 8b passing through the casing 3 which is connected to the extension 1 of the shaft 2, and one or more coupling discs 9 freely rotatable on eccentrics 12 keyed at 13 to the shaft 5. The plate 10 of each of the discs 9 has two openings 14, 15, the opening 14 being provided with a ball bearing 16 centred on an eccentric disc 17 on one of the bolts 4 passing through the extension 1 and the discs 9, friction lining 18 being also provided at the periphery of the discs 9. Rotation of the shaft 2 causes an eccentric rotary motion of the discs 9 on the shaft 5 and an oscillatory movement relative to the discs 8, and prevention of this relative oscillatory movement causes rotation of the driven shaft 5. Blocks 20 slidable on the bolts 8b carry eccentrically mounted cylindrical weights 19 by means of trunnions 21. As the speed of rotation of the shaft 2 increases, the weights 19 tend to rotate on their trunnions and press the discs 8, 9 together, preventing the relative oscillatory movement of the discs 9 and thus transmitting the drive. In a modification, the bolts 4 are not carried through the discs 9, the eccentric rotary movement of which is produced by frictional engagement with the discs 8, and the pressure for this purpose and for stopping the relative oscillatory movement of the discs 9 may be produced by means of springs carried on the bolts 8b which urge an end plate, slidable axially on 'the shaft 5, into contact with the discs 8, 9.

Title: Fluidised bed temperature conditioner and method of controlling temperatures of fluid process streams
IPC: F28D13/00
Filed: 1954-04-15
Abstract: <PICT:0753904/III/1> A fluidized bed temperature conditioner for continuously controlling the temperature of a fluid stream of reacting materials at successive points along its path, comprises a housing (10, 12, 13) of which the lower portion is divided into compartments (A, B, C) by upright partitions (18, 18a), each of said compartments having means (e.g. 31) for admitting fluidizing gas thereto; means (52) for discharging gas from the upper part of the housing; means for independently controlling the temperature of a fluidizing bed maintained in each compartment; and one or more heat-conductive tubes (15) for said fluid stream, at least a portion of each tube lying within each compartment. The corresponding method of controlling the temperature of a process stream is not limited to the use of apparatus in which the compartments are in free communication above the partitions.  The numerals refer to the illustrated apparatus, which also embodies the following features. The housing comprises a refractory bottom 10, side walls 12 and arch 13, and is divided into compartments by refractory partitions 18 and 18a, adjustably bolted to the bottom.  The tubes 15 may pass through the partitions as shown or pass thereover, and may be in the form of coils.  Hot combustion and fluidizing gases are supplied from a refractory combustion chambers such as 19 within which is a burner supplied with independently regulated fuel and primary and secondary air through pipes 25, 28 and 22 respectively, and pass through a duct 30 surmounted by a deflector 31.  Several such arrangements may be employed in each compartment and distributing grids may also be used. Alternatively, combustion may be carried out above the floor 10. Additional cooler fluidizing gas may be supplied through ducts 36 from wind-box 35 from line 40, supplying e.g. atmospheric or preheated air and/or recirculated flue gas from duct 44.  One or more compartments may have means for admitting a liquid to be vaporized and thus cool the fluidized heat-conducting solids, such as perforated pipes 47 supplied with liquid through pipe 51.  Suitable adjustment of the pressure in the bed may be necessary to avoid recondensation of the liquid, and when starting up it may be necessary to introduce steam or other gas initially.  Fluidizing gases emerge through a duct 53 and entrained solids are separated in cyclone 54 and returned to one of the compartments by dip leg 55: the levels in the various compartments are in this case maintained by overflow.  In general the levels may be at or near the tops of the partitions, or (less desirably), slightly above.  Suitable solids for use are metal oxides of the type used as catalysts and (preferably) sand particles of diameter 0.005-0.1 inch: the fraction of voids is usually 0.3-0.8; in order to obtain high heat transference, the "Reynolds number" (definition given) should be at least 2 and preferably above 5.  Reference has been directed by the Comptroller to Specification 587,774.

Abstract: 1449107 Combined catalytic-electrolytic heavy water production ATOMIC ENERGY OF CANADA Ltd 19 March 1975 [3 May 1974] 11473/75 Heading C7B Heavy water is prepared in a two-stage process in which liquid water from feed or a previous enrichment stage is passed in countercurrent with H 2  through a H 2 /H 2 O deuterium-exchange catalyst and then passed to the cathode compartment of a diaphragm electrolysis cell to be recovered therefrom enriched in D 2 O. The hydrogen is obtained from the cathode compartment and is recycled to the anode compartment where it is at least partially consumed by the anode. The D20 depleted water from the anode side is either recycled to a previous stage or discharged. Electrolyte e.g. KOH may be recovered from each compartment outflow and is recycled. The catalyst may comprise one or more Group VIII metals covered with resin permeable to water vapour and H 2  but impermeable to liquid water. The H 2  outlet and water inlet to the catalyst may pass through a de-humidifier and the H 2 O inlet and H 2 O outlets through a humidifier, as is conventional. The cell may comprise a plurality of compartments electrically connected in series, with parallel fluid-flow. Each anode may comprise a fuel cell anode having a coarse and a fine pore layer, the former abutting an enclosure behind the electrolyte and to which the recycled H 2  is passed for absorption by the anode.

Abstract: 644,180. Public address systems. PHILIPS ELECTRICAL, Ltd. April 27, 1948, No. 11534. Convention date, April 29, 1947. [Class 40 (iv)] [Also in Group XL (c)] In a public address system in which the output from a loudspeaker 5 is maintained at a predetermined level above the ambient noise by a control voltage from an auxiliary microphone 6, the control voltage is taken only when there is no output from the loudspeaker, but control of the system amplifier is maintained by a condenser 11 in a circuit having a long time constant. The speech currents from microphone 3 pass through an amplifier stage 1 provided with automatic gain control to stage 2 in which the degree of amplification is determined by the potential applied to a line 8 by a control circuit 7, shown in detail in Fig. 2. In the control circuit the potential across the condenser 11 and thus the control potential at 8 is determined by the conductivity of valves 12 and 13 which form a potentiometer across the supply 14, 14. The former valve is under the control of the output from the auxiliary microphone 6 over line 10 when no speechcurrents are flowing, but both are cut off by the output from transformer 20 when speech currents render the valve 18 conductive. A modified control circuit is described with reference to Fig. 3 (not shown). The invention is stated to be applicable also to a wireless set or a radiogram.
