Title: Bubble generating apparatus
IPC: B01F3/04
Filed: 1976-09-24
Abstract: 1532566 Mixing apparatus MITSUBISHI PRECISION CO Ltd 24 Sept 1976 [4 Nov 1975 27 May 1976] 39842/76 Heading B1C A device for immersion in a body of liquid to generate gas bubbles therein comprises a nozzle 10 to which liquid is supplied under pressure, a target 20 upon which the liquid from the nozzle impinges, and a means 25 for supplying gas to a region adjacent to the target. Impingement of the jet on the target causes it to be dispersed through an angle α forming a low pressure region into which gas is entrained. The angle of dispersion may be altered by means of a sleeve 16 adjustable axially of the nozzle. As shown the target and gas supply means are carried on a rod 22 and may be adjustably spaced from the nozzle. In modifications the target may be carried by the gas supply means (see Figs. 3 and 4, not shown) and the rod 22 may be replaced by a gas supply pipe (see Figs. 5 and 6, not shown). The target may be non- circular and/or the gas supply means arranged to generate bubbles in a non-circular pattern.

Abstract: 1356412 Treating aluminium residues ALCAN RESEARCH & DEVELOPMENT Ltd 1 Sept 1971 [17 Sept 1970] 40849/71 Heading C7D Material separated from a body of molten aluminium, e.g. skimmed from the surface of a casting furnace, which material contains aluminium metal and various compounds of aluminium and possibly of other metals, also, is treated in a confined region with dry steam at a temperature below the melting-point of the aluminium. The treatment converts the material into a substantially dry form which can be classified by particle size into a fine fraction which contains a higher proportion of compounds, and a warm fraction which contains a higher proportion of aluminium. The material to be treated generally contains alumina, fluorides, and carbides, nitrides &c. of aluminium and other metals, e.g. sodium; dry steam hydrates the alumina and decomposes the carbides and nitrides; the resulting fine fraction can be utilized in an aluminium reduction cell, while the warm fraction is suitable for remelting thus affording recovery of the metal. Preferred conditions are a temperature between 120 and 205 ‹C. at a pressure of 1 to 16 kg/sq.cm. for 4 to 10 hours The process is especially preferred when the separated material contains at least 20 wt. per cent aluminium.

Abstract: 1502475 Riveting FURMA MFG CO PTY Ltd 6 Oct 1975 40870/75 Heading B3U A pair of sheets 32, 33 (Fig. 2) are riveted together by forcing the shank of a rivet 34 through the sheets and then deforming the shank (Fig. 5) against an anvil 31 to prevent withdrawal of the rivet. Initially the rivet, is fed laterally into a tubular carrier 17, and then forced to the right by an hydraulically actuated plunger 20. The rivet is guided by a flexible washer 24 before entering the sheets. The sheets are locally deformed into a die recess 29 in a pivoted plate 25 before the rivet shank forms a hole in them, the deformation enabling the rivet head to be flush with the surface of sheet 32 after riveting.

Abstract: 1486846 Self-processing cameras FUJI PHOTO FILM CO Ltd 9 Oct 1975 [12 Oct 1974] 41517/75 Heading G2A In a camera for self-processing film units the pressure members through which the film unit passes during processing are arranged skew to each other. As shown, the exposed film unit, which carries at its forward end a pod of processing solution, is passed between rollers 3 and 4, the pod thus being ruptured and the processing solution spread between the two sheets forming the film unit. The rollers are skewed with respect to each other, and as seen in Fig. 2 both are inclined to the direction of travel A of the film unit, although one of them may be normal to this direction. The rollers are spring-urged towards each other. One or both rollers may be replaced by fixed bars. The arrangement is intended to improve the evenness of distribution of the processing solution between the sheets, and experimental results are given in which the distance between the rollers and the angle of crossing are varied.

Title: Encoding detecting and or correcting of data

Filed: 1970-09-02
Abstract: 1318250 Digital error detection and correction HONEYWELL Inc 2 Sept 1970 [29 Oct 1969] 42047/70 Heading G4A Source data is organised into k data segments of n bits each and means are provided to generate a first series of b check bits as the exclusive- or summation: and to generate a series of n check bits as the exclusive-or summation: Using these check bits errors may be detected and, in some cases, corrected. The data comprises an array of 1's and 0's (e.g. on tape or disc files) as shown in Fig. 3 and a check digit is generated for each column, a check digit is generated for either the left or right diagonal, and a check digit may be generated for the other diagonal. Column check bits.-Each column check bit = j = k Cm = # # Bjm which gives the same result j = 1 as a simple parity check. Diagnonal Check Bits.-As shown on Fig. 3 the diagonals use an "end around" technique which also gives the same results as a simple parity check on the indicated bits. The end around shifting can be defined in terms of modulo n numbers where if the sum or difference of the modulo numbers exceeds the limits of from 1 to n, the result is corrected by adding or subtracting n for values which are above or below the limits. The left diagonal is defined as and the right diagonal as The actual bits used in the diagonals are further described with reference to Figs. 1 and 2 (not shown).  A data segment may extend along a column rather than a row as long as K # n. Error Detection.-The check bits are calculated as described above using an apparatus in Fig. 4 (not shown) and the array has three rows of check digits as shown in Fig. 3. When the data array is used again the check digits are recalculated using the same method and the two sets of check digits compared using exclusive ORing to produce three error segments (Figs. 8a to 8e not shown). Alternatively two error segments (only one of them a diagonal) may be used but three segments improve the chances of correcting an arror. If two of the three error segments contain all zeros the data is correct. The third error segment here merely permits a majority decision. If only one contains all zeros the data is erroneous and uncorrectable but if none contains all zeros the data is erroneous but possibly correctable. It is stated that it is possible to correct up to n-1 errors in a single data segment of n bits. All three of the error segments are overlayed by the proper combination of cyclic modulo "n" shifts (only the diagonals are so shifted). The left diagonal is cycled (modulo n) left, the right diagonal is cycled right and a three way comparison performed, agreement indicating error in that segment. This is done for each segment, failure to find agreement indicating an uncorrectable error. Actual correction may be made manually, by computer program or by special hardware. It is stated that n is preferably a prime number so that there can be no factors permitting comparison equality for any subpatterns.

Title: Improved apparatus for controlling a mass flow rate of liquid in a chemical process

Filed: 1969-08-26
Abstract: 1287435 Automatic mass flow control TORAY INDUSTRIES Inc 26 Aug 1969 [29 Aug 1968] 42460/69 Heading G3R In a chemical process, liquid is supplied to a container and removed therefrom under the control of automatically operated on/off and variable control changes in weight controlling the variable control to maintain a constant mass flow. In Fig.1, an on/off valve or pump 1 is operated periodically under the control of a device 7 so that liquid is supplied intermittently to a weighing container 2 from which it flows continuously through a flow regulator 3. A force-balancing electrical or pneumatic transducer associated with container 2 produces a signal W which controls device 7 so that the supply of liquid is stopped when the weight reaches an upper limit and started when it reaches a lower limit. A device 5 associated with a source of timing pulses 4 repeatedly detects either the time taken for the weight in the container to fall from one predetermined value to another or the loss in weight in a given time. This measurement is utilized to calculate the average mass flow which is compared with a desired flow by a unit 6 so that any error is effective to control regulator 3 to restore the desired flow. In one modification, the on/off value or pump 1 is arranged in the outlet from container 2 and the regulator in the inlet. In another modification, the rate of flow is corrected by controlling the datum of an automatic system stabilizing gas pressure in an enclosure surrounding the weighing container. The enclosure may be heated or cooled to achieve a desired temperature.
