Title: Method and apparatus for effecting continuous filtration
IPC: B01J47/10
Filed: 1962-12-28
Abstract: Nearly-continuous filtration is effected by feeding a liquid to be filtered upwardly at 3 (the Figure, not shown) in a first vessel 2 containing granular filtering material 1 so that material above the liquid feed level is pushed upwardly in layer form and material below that level is pushed downwardly, effecting countercurrent contact between the liquid and the filter material positioned above the liquid feed level and discharging treated liquid from the top of the first vessel at 4, interrupting the feed of liquid into the first vessel by closing a valve 5 and discharging a part of the liquid at substantially the feed level by opening a valve 6, thereby to allow filtering material above the liquid feed level to descend and be supplemented by fresh filtering material charged into the top of the first vessel, transferring filtering material from the bottom of the first vessel to the top of a second vessel 9, washing it therein by washing-liquid 10 fed in at the bottom, and recycling filter material from the bottom of the second vessel to a valve-controlled hopper 7 at the top of the first vessel, the time during which feed of liquid to the first vessel is interrupted being small relative to the time during which liquid is fed to the vessel.

Abstract: 1280517 Packaging food products; endless chain conveyers FMC CORP 8 Oct 1969 [31 Oct 1968] 49462/69 Headings B8A and B8C [Also in Division A2] Means for purging the air space and of reducing the head space in a partially filled container having an unsealed mouth comprises a carrier for the container having means for applying tension across the mouth of the container so as to provide a one-way valve, at least one trough, guide means to guide the carrier along a vertical path downwardly and upwardly through at least one liquid bath in the trough and means to heat the liquid in the bath. As shown, containers 22 carrying a food product and made from a heat sealable laminated film material having an open mouth 36, are fed at a feeding station F into chamber PC of a housing 40 containing boiling water W and thence into a cooking chamber C containing boiling water W and saturated steam at 212‹ F. introduced through an inlet 56b. Thereafter the containers are hermetically sealed by a mechanism 57 and are then moved under cooling sprays 58 to a discharge station D. The containers are moved through the apparatus by an endless chain conveyer 55, the containers being mounted on carriers 82 suspended between a pair of chains 60, 62 of the conveyer. Each carrier includes a base 84 and pairs of spring arms 86 carrying clamps 88 to which the mouths 36 of the containers are attached and by means of which the mouths are tensioned to provide a one way valve at the mouth of each container. Each container is clamped to the base 84 by a clamp 90. In operation movement of the containers through the chamber PC in the direction shown, progressively diminishes the size of the headspace and reduces the amount of air as well as the gases formed during the cooking process, so that the headspace is filled with substantially pure water vapour or steam when the containers move into the chamber C where they are further heated by steam and periodically immersed in water W thereby hydrostatic pressure acting on the containers purges them of the cooking gases. In another embodiment Fig. 9 (not shown), the containers are moved successively into hot and cold troughs and finally into a hot water cooking trough. Specification 1,212,790 is referred to.

Abstract: 1,203,774. Programmed control of machine tools. HUGHES AIRCRAFT CO. Oct.31, 1967 [Nov.29, 1966], No.49469/67. Heading G3N. The data indicative of the present desired position of a movable element is stored in a position register and is changed by pulses from a movement-sensing transducer, the contents of an overshoot register, containing data indicative of movement of the element past a preceding desired position, being algebraically summed with the contents of the position register before movement of the element to the present desired position is completed. As shown, information input equipment 10, responsive to a photo-electrically read punched tape, reads out serially presented signal groups which are distributed by controls 12 through a logic 18 to a position count register 16. At a predetermined count in the register 16 a feed axis drive 20 is enabled by more signals Mn or Mp from control 12. A feed axis 22 movement occurs together with a movement of a coupled machine element, not shown, which is detected by a transducer 24. The output of the transducer is coupled to a generator 26 producing pulses P, N enabling logic 25 deriving count pulses P<SP>1</SP> N<SP>1</SP> which, through count gates 30 cause counting of the register 16 towards the zero count condition. At zero count logic 28 is enabled and a signal PZ takes up a level disabling the position of control 12 producing signals Mn, Mp whereby drive 20 ceases operation. A zero logic 34 is also coupled to enable gates 30 so that an overshoot register accept pulses P<SP>1</SP>, N<SP>1</SP> from logic 25. Upon starting the next positioning operation when the contents of register 14, as indicated by logic 34, is not zero, a clock logic 36 produces clock pulses CLK which transfer the count in the register 14 into the register 16. The transfer occurs one count at a time and is dependent on the relationship between the signs of the register so that the contents of the registers are algebraically summed before the movement of the machine element is initiated. The registers 14, 16 is a reversible up/down counter comprising a digital counter formed by a plurality of JK flip-flops coupled for successive enabling by the state of the preceding flip-flop and enabling input signals.

Title: Error detection and correction
IPC: H03M13/19
Filed: 1970-10-20
Abstract: 1316348 Error handling INTERNATIONAL BUSINESS MACHINES CORP 20 Oct 1970 [25 Nov 1969] 49656/70 Heading G4A Data processing apparatus for processing data words containing k data bits and (n - k) check bits according to an (n, k) cyclic code includes (n - k) logic circuits arranged to feed result signals into respective stages of an (n - k) stage register and gating means arranged to feed the register contents and c > n - k data (or data and check) bits at a time into the logic circuits (with zero packing where necessary) according to a pattern defined by (c + n - k) rows out of the first (c+n+# - k) rows (the omitted rows being intermediate rows) of the autonomous matrix for the code so that, for the selected submatrix, gating occurs for each element a ij  = 1 from the ith bit to the jth logic circuit where i # c and from the (i - c)th register stage to the jth logic circuit where c < i # (c+n-k), where k, n, c, # are positive integers. For decoding (error detection and correction), a 72-bit word having 64 data bits and 8 check bits, is applied from a 72-bit input buffer 18-bits-in-parallel at a time to EXCL-OR trees feeding the 8 positions of a feedback shift register the outputs of the positions of which are fed back to the EXCL-OR trees. When the whole word has been applied, all zeros in the register indicates no error and the word in the input buffer is applied 18-bits-in-parallel at a time to a 72-bit output buffer. An even non- zero number of ones in the feedback register indicates an uncorrectable double (or worse) error, whereas an odd number of ones indicates an odd number of errors which is assumed to be one. In the last case, a pattern detector responds to any of 18 particular patterns in the feedback register to invert (correct) a corresponding bit of the first 18 bits as they are applied to the output buffer, or a corresponding bit in any one of the other groups of 18 bits as they are applied to the output buffer, the feedback register being shifted before each of the latter three groups are transferred. The number of EXCL- OR circuits needed is reduced by designing the circuit as if the input word is of 108 bits, taken 27 bits at a time, the connections and EXCL- OR circuits corresponding to those of the 27 bits other than the 18 actually-existing bits being omitted. The assignment of the actual 18 bit positions to the notional 27 bit positions is chosen to avoid those bit positions which would require an above-average number of EXCL-OR circuits (thus reducing the total number of EXCL-OR circuits) except that gross disparity in tree size is avoided (to avoid excessive differences in delay times) and of course the maximum allowable word length for the shortened cyclic error-correcting code used must not be exceeded. A similar feedback shift register is used for encoding (production of check bits).
