Title: Multistage planetary gear assembly
IPC: F16D3/04
Filed: 1976-11-18
Abstract: In order in the planet gearing to achieve uniform power division by distributing the torque of the sun wheels to the planet wheels, the planet carriers (19, 27) of the gearing stages preceding the last gearing stage and the inner sun wheels (25, 35) of the gearing stages following the first gearing stage are radially unsupported and are coupled together rotationally by means of a respective coupling part which compensates centre deviations. The radially unsupported planet carriers (19, 27) and the radially unsupported inner sun wheels (25, 35) each have a groove (22, 30; 32, 41) on their mutually facing sides. On each of its faces, the radially unsupported coupling part has a strip, one of these strips being in engagement with the groove (22, 30) of the adjacent planet carrier (19, 27) and the other being in engagement with the groove (32, 41) of the adjacent inner sun wheel (25, 35). By means of these couplings, it is possible to achieve lower production costs and a smaller overall length. <IMAGE>

Abstract: 1322928 Anaesthetic apparatus MEDIADA AB 13 Oct 1970 [9 March 1970] 48562/70 Heading A1T [Also in Division F2] Apparatus for analgesic narcosis using a mixture of oxygen gas and nitrous oxide gas comprises a valve 3, 37 for controlling oxygen flow, an oxygen-pressure regulator A, a balance regulator B for nitrous oxide arranged for control by oxygen gas-pressure, and a proportioning valve D for regulation of the oxygen/nitrous oxide gas-mixture ratio, the valves and regulators being interconnected by internal passages in a block 20 on which they are mounted, and the regulator B comprising chambers 42, 48, for oxygen and nitrous oxide respectively, separated by diaphragms 43, 45 between which is a chamber 46 connected to the atmosphere. Oxygen passes from an inlet 24 via a diaphragm-type pressure-regulator A, valve 3, 37 and valve D where it is mixed in a chamber 65 with nitrous oxide passing to valve D from an inlet 21 via a non-return valve 23, regulator B and a throttle valve C. The gas mixture at near atmospheric pressure passes from chamber 65 in to a reservoir 2. The throttle valve C comprises a chamber 55 for oxygen the pressure of which acts on a diaphragm 9 to open a valve 56, 54 by means of a chamber 59 which communicates with the atmosphere. The valve D comprises valve seats 5, 6 and a valve member 11 movable towards or away from one seat and respectively away from or towards the other seat by means of a knob 70. The reservoir 2 fills up with the gasmixture until upward movement of a rod 15 closes valve 3, 37 cutting off the oxygen supply and thereby closing the regulator B and valve C. The patient breathes in the gas from reservoir 2 via a non-return valve 17, decrease in the reservoir-volume opening the valve 3, 37, and thus regulator B and valve C. If the pressure in reservoir 2 becomes sub-atmospheric, a valve 18 opens to connect the reservoir to the atmosphere.

Abstract: 1353109 Electrolyte additive in cells OMF CALIFORNIA Inc 24 Oct 1972 [18 Nov 1971] 49017/72 Heading H1B An electrolyte for an electric energy storage device comprises an aqueous solution containing a metal halide and the (unidentified) reaction product of an aldehyde with ammonia or an amine. Virtually all metals are suggested for the halide with the exception of the alkali and alkaline earth metals. Zinc or iron cobalt or nickel is preferred. Chlorine and bromine are suggested halogens. The particular application is to zinc-chlorine cells involving the use of chlorine hydrate. The aldehyde reaction product in the electrolyte acts to prevent dendrite formation during charging of the cell. It may be necessary to add a concentrate of the reaction product to the electrolyte immediately prior to each recharging of the cell. A great variety of amines and aldehydes are suggested. They may be reacted together in an aqueous system heated to between 50‹ and 200‹C. and used in the solution thus formed. The only specific example of an electrolyte comprises aqueous zinc chloride containing a reaction product of ethylenediamine and glyoxal.

The carbonaceous material used in the reduction steps may be coal, coke, oil, natural gas, or mixtures thereof. The particulate ore, e.g. magnetite, having a particle size up to 10mm is fed into pre-reduction fluidized bed furnace 501 where it reacts with pre-heated air and oil introduced through conduits 513, 514 respectively. From there, the partially reduced material passes through a further pre-reduction furnace 502, and into a complete reduction induction furnace 503 containing molten iron with C in solution. The material entering furnace 503 contains preferably 60-80% Fe, and the remainder is reduced to Fe by the carbon in the melt. The exhaust gases from the furnaces 501, 502, 503 are cleansed of dust in cyclones 515, 519, and burnt with air in steam generator 504 which drives a turbine'505 and generator 507. In another embodiment, Fig.4 (not shown), the two reduction steps occur in the same reactor. Magnetite concentrate is pre-reduced in a coke bed (407) floating above a slag layer (409) in a completely closed reduction furnace (401). The pre-reduced concentrate falls through the slag layer into an iron melt (408) into which oil is pumped to effect the reduction.

Title: Circuit arrangement for an automatic exposure device

Filed: 1972-10-31
Abstract: 1391800 X-ray exposure control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 31 Oct 1972 [3 Nov 1971] 50154/72 Heading G1A In an exposure control system generating a switch-off pulse when an input signal exceeds a threshold level, the input signal is passed through a low pass filter, a band-stop filter comprising an active band-pass filter and an adding stage, and an interference suppression device to a comparitor constructed as an FET input differential amplifier with positive feedback, and a thyristor output  stage. In an x-ray exposure control system a plurality of ionization chambers (1,2), each provided with an electrometer amplifier, are connected via a  selector switch (3) to the input 4 of the control circuit. The signal is applied to the input of a low pass filter (5) utilizing an amplifier B1 to remove high frequency interference. Mains frequency signal components are then removed by means of a band-stop filter comprising amplifier B2, B3 and B4 arranged to form an active band-pass filter (6) the pass frequency of which can be selected by switch Sch 1, and an adding stage 7 utilizing an FET input stage B5 to an amplifier B6. Automatic offset correction is provided by switch Sch 2 which is closed before the start of the measurement so that the output of the adding stage is zero irrespective of the input level. At the start of the measurement Sch 2 is opened and the initial voltage level stored on capacitor C11 provides the reference bias to input stage B5. The output of the adding stage is connected to an interference suppression circuit 9 utilizing transistors B8, B12, B13 and B14 to detect the presence of rates of change higher than a threshold level and short circuit the signal connection to the following stage. This prevents pulses due to flash overs in the x-ray tube reaching the output stages and causing premature termination of the exposure. The capacitor C25 provides a 1 mS time delay after the interference pulse to ensure that any decaying oscillators are also suppressed. The signal is then applied to a comparitor (11) utilizing a pair of FETs B10 provided with a positive feedback loop by means of transistors B9 and B15. The reference voltage, which depends on the film used for the x-ray exposure, is applied via resistors R49 and R42. When the increase in the input voltage exceeds the reference level the comparitor switches and the output is differentiated by capacitor C19 and the associated resistors and used to provide a triggering signal to a thyristor G7 which provides outputs at terminals 15 to terminate the exposure.
