Title: Timing device for washing machine
IPC: D06F37/30
Filed: 1972-07-25
Abstract: 1353714 Time switches KELVINATOR AUSTRALIA Ltd 25 July 1972 [28 July 1971] 34611/72 Heading H1N To avoid the necessity of impulse stepping of a timer cam shaft to ensure quick breaking of contacts actuated thereby, a timer is provided with two cam lobes on a common shaft driven by a timer motor via speed reducing gearing, one cam lobe acting on a snap-action switch and another acting on a slow make/break switch, the lobes being mutually arranged such that the slow make/break contacts are still closed when the snap contacts open. As shown, a timer, suitable for a semi-automatic washing machine, comprises a motor 11 driving a long pinion 13 via gearing 12, and a cam shaft 17 has a gear 16 meshing with pinion 13 and coupled to shaft 17 by friction washers 22. Shaft 17 carries a cam 25 acting on a microswitch 26 and cams 27, 28, 29 acting on respective slow make/break switches 31, 32, 33. The motor 11 is fed from supply via switch 31 but the supply to the washing machine motor (36, Fig. 2, not shown) is via switch 26 and the two switches 32, 33, which are of changeover type for reversing the motor (36) by means of a starting winding (37) and are in series with switch 26. The cam lobes are arranged such that switches 32 and 33 are made before switch 26 closes and switch 26 opens before switches 32, 33 change-over. A knob 24 enables the cam-shaft 17 to be rotated to select functions such as WASH, SPIN, or WASH AND SPIN, there being intermediate OFF positions. The shaft 17 may also be moved axially to switch the washing machine OFF during any function. This moves cam 25 clear of switch 26, which is of the normally-open type, but does not disengage the other lobes from their switches, so the timer motor 11 continues to run till deenergized by switch 31 at a normal OFF position. In a second embodiment (Figs. 4, 5 and 6, not shown) the edge cams 25, 27, 28 and 29 are replaced by a single face cam (51) with a plurality of tracks acting respectively on a snap switch 26 and pivoted contact arms (61) of "slow" switches (60). The snap switch 26 is held in position by a clip (58) for easy replacement. An additional cam track may act on a second snap switch 26 for a heating circuit. In each embodiment a spring clip 45 co-operates with grooves 46 for axial location of shaft 17.

A coded-scale shaft-position digitizing system of the type in which sensing elements feed a logic circuit so as to produce the desired coded signals (e.g. pure binary from either lead/lag sensing elements or a Graz coded scale) is modified in that a store is interposed between the sensing elements and the logic circuit and in that the output of the logic circuit is fed to a set of gates, the store and gates being strobed by staggered clock-pulses produced independently of the motion of the scale. In this way spurious output combinations which might arise each time the scale moves because of the time taken by the logic circuit to recode correctly signals received from the sensing elements, are prevented.

Title: Hydrous alumina and reforming catalysts based thereon
IPC: C01F7/428
Filed: 1958-10-31
Abstract: A hydrous alumina, consisting on a total solids basis of 5-50% by weight of a -alumina monohydrate and 50-95% by weight of alumina trihydrate predominantly in the form of b -alumina trihydrate is prepared by reacting substantially pure, preferably at least 99,9%, <PICT:0901588/III/1> aluminium metal with excess water, in the absence of acid, and in the presence of mercury or a mercury compound, e.g. mercuric chloride, present in an amount of from 0,25 X 10-6 to 100 X 10-6 pounds of mercury per square inch of surface of the aluminium, the temperature being maintained at 60-100 DEG  F. and the pH being maintained within 7-10 until at least the major proportion of the metal has been converted to alumina in the form of a slurry.  The aluminium preferably has a surface area greater than 1000 square inches per pound.  The mercury may be removed from the slurry by boiling or by heating with steam.  The hydrous alumina may be used in the preparation of catalysts, especially for hydrocarbon conversion reactions carried out in the presence of hydrogen, for example reforming, hydrocracking, hydrodesulfurization, and isomerization.  Thus the hydrous alumina may be impregnated with metals or metal compounds especially of chromium, molybdenum, tungsten, uranium, iron, nickel, cobalt, platinum, palladium, ruthenium, osmium, rhodium, and indium, for example after filtration or drying or calcining of the alumina.  The dried composite may be used as such or ground, mixed with water or a lubricant such as stearic acid, and pelleted.  In Fig. 2, aluminium is converted into shavings in mill 10, converted to hydrous alumina in 14 in the presence of mercuric chloride, and the slurry formed is boiled in 25 to remove mercury. This slurry is passed to 31 where it is impregnated with chloroplatinic acid solution and treated with hydrogen sulphide. The treated slurry is dried in 36 in a stream of air, crushed in 42, mulled with water in 44, extruded to form pellets in 46, dried in belt dryer 47, and calcined in kiln 49, the product being collected in container 57.  Catalyst compositions specified include nickel tungsten sulphide, molybdenum oxide-cobalt oxide, and molybdenum oxide with nickel or iron oxide with or without cobalt oxide.  In an example the alumina was impregnated with palladium chloride, treated with hydrogen sulphide, dried, pelleted and calcined.  The pellets were employed as catalyst in the hydrogenative desulphurization and denitrogenation of a naphtha, prior to reforming, at a temperature of 675 DEG  F., a pressure of 425 p.s.i.g., a liquid hourly space velocity of 5, and a hydrogen supply rate of 500 st.cu.ft./barrel.

Abstract: 1,101,723. Correlators. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 1 Feb., 1967 [31 Jan., 1964], No. 35162/67. Divided out of 1,101,721. Heading G4R. [Also in Division H3] A correlation circuit switches one of two constant energy sources into circuit with integrating means in dependence on the positive or negative sense of the correlation of at least two variable amplitude electrical inputs, whereby the output signal from the integrating means is independent of the absolute as distinct from the relative input amplitudes. With three variable amplitude inputs A, B, C, from equally spaced taps on a delay line carrying a speech waveform, the autocorrelation function of the waveform is obtained as follows. If A<B, transistor T1 conducts and T2 is cut off, producing a signal on line 48 which enables T3 and T6 to respond to B and C, so that if B>C, T3 will conduct, passing a signal to T10 via T9 and line 50, whereas if B<C, T6 will conduct, passing a signal to T11over line 51. On the other hand, if A>B transistor T2  conducts and T1 is cut off, enabling T8 and T5 to respond to B and C, so that if B<C, T8 conducts to pass a signal to T10, while if B>C, T5 conducts to pass a signal to T11 via T12. Thus if A<B<C or A>B>C, T11 conducts to pass a constant positive current to the (adjustable) RC integrator feeding output line 52, and if A>B<C or A<B>C, T10 conducts to pass a constant negative current to the integrator. A two-input correlator may be obtained by earthing B.

Abstract: 1482779 Amplifiers WESTINGHOUSE ELECTRIC CORP 12 Aug 1974 [15 Aug 1973] 35466/74 Heading H3W A feedback amplifier is arranged to fail safe, i.e. the output signal does not increase upon failure of any of the elements of the feedback network. The amplifier is of the differential type, the signal being fed to the in-phase input terminal 20, while the gain is controlled by a negative feedback network connected between the output terminal 24 and out-of-phase input terminal 32. The feedback network comprises a four terminal capacitor 28, the amplifier output being connected to terminal 26 while the signal output is taken from terminal 36. Terminal 30 is connected to the input terminal 32 while terminal 38 is connected via resistor 40 to terminal 34 and via capacitor 42 and resistor 44 to a bias point + V. Component values are such that the gain is determined by the capacitors. Shortcircuit failure in capacitor 28 reduces the gain to zero, while short-circuit of capacitor 42 applies a cut-off bias to the amplifier. If lead 26 or 34 becomes disconnected no signal reaches terminal 36 while if lead 30 breaks the D.C. bias is removed and the amplifier goes into saturation. If lead 38 breaks or capacitor 42 becomes disconnected, feedback brings down the gain.

Abstract: 1277906 Treating grain with gases. H N BARHAM and H N BARHAM JNR 15 July 1969 [26 July 1968] 35504/69 Heading A2Q A method of treating the kernel structure of raw grain to adsorb at least one gas, e.g. as a step in the degradation of the grain to extract the starchy portion for industrial uses or for use as an animal feed, comprises placing raw grain in a container, evacuating the container to a first pressure, introducing at least one gas into the container with increase of pressure in the container, halting the introduction of the gas into the container and sealing off the container, and maintaining the container in a sealed condition a sufficient time for the grain to adsorb enough gas to reduce the pressure in the container substantially. The gas may be introduced into the container at a rate at least equal to the adsorption rate of gas by the grain as the pressure in the container is increased. After sealing, the container is maintained in this condition until the pressure ceases to change, whereby grain having an unchanged moisture content, e.g. 5 per cent by weight, and between 0.15 and 5 per cent by weight of adsorbed gas is produced, using an evacuation pressure of between 0 and 173 mm. of mercury, and an increased pressure, during introduction of the gas, of about 102 to 1,100 mm. of mercury. The gas is preferably sulphur dioxide, hydrogen chloride, hydrogen sulphide, ammonia, chlorine, ethylene or ethylene oxide. After receiving the gas treatment, the grain may be further treated in another sealed pressure container to steam at a peak pressure of at least 2.8 Kg. per square centimetre gauge, until the required degree of degradation has been accomplished.
