Title: Improvements in or relating to the method of ageing of meat
IPC: A23L13/70
Filed: 1948-02-20
Abstract: 653,903. Ageing meat. INDUSTRIAL PATENTS CORPORATION. Feb. 20, 1948, No. 5054. Convention date, Feb. 24, 1941. [Class 49] The ageing of fresh meat for improvement of tenderness and flavour is effected by confining the meat in a ventilated zone at a temperature promoting ageing and a humidity tending to cause dehydration, and adjusting the degree of ventilation so that evaporation of moisture from the meat raises the humidity in the zone to just below the saturation point and sufficiently high to promote ageing without substantial dehydration but insufficiently high for mould and slime formation. The zone may be surrounded for example by freely circulating air of temperature 29-30‹F and humidity 80-85 per cent, the ventilation being such that a complete change of air within the zone is effected every 24 hours; under these conditions the ageing is effected in 10 days. Described with reference to the drawings is a refrigerated chamber holding cases B (Fig. 4), of compartments 16 for cuts of meat, the doors 26 of which compartments have perforations 24 or holding open shelves supporting boxes 12 (Fig. 3), for cuts of meat, which boxes have tightly fitting tops 20, corrugated bases 22, and, in the sides, perforations 24 of #-“ inch diameter.

Title: Impulse-Pair Detector
IPC: G01S13/78
Filed: 1967-02-03
Abstract: 1,157,191. Detectors for spaced pulse pairs. INTERNATIONAL STANDARD ELECTRIC CORP. 3 Feb., 1967 [4 Feb., 1966], No. 5319/67. Heading G4H. A detector for pairs of input pulses having predetermined time spacings comprises a cyclic counter 7 to generate pulses having equally spaced time positions in each counting cycle, each pair of input pulses being separated by a time interval which is a whole multiple of the spacings between counter output pulses and the longest interval being equivalent to the period of the counting cycle, distributer gates 9 responsive to coincidence between input pulses and counter pulses, the gate outputs 10 each passing to two signal stores 13a, 13b enabled in alternate cycles of the counter, there being a plurality of coincidence detectors 31.3, 31.4 &c. each responsive to the simultaneous presence of a signal from the output of a respective one of the signal stores and an output from a gate 9. The input pulses are applied at terminal 1 and the first input pulse sets flip-flop 3 to open gate 4 to allow pulses from oscillator 5 to pass via divider 6 to counter 7. It also causes flip-flop 14 to be set. A further flip-flop 17 is set by the first input pulse and reset at the end of a counting cycle by the output from the 21 stage of the counter. The outputs from flip-flop 17 alternately enable the input gates 11.a and 11.b of stores 13.a, 13.b. The outputs a, b of the stores 13.a, 13.b are passed via Or gates 20.a, 20.b to cause the flip-flop 3 to reset if no signals are stored in any cycle to prevent the counter starting another cycle, it being assumed in this case that the counter was started by a spurious pulse. Gates 31.3, 31.4 &c. are provided for all possible pairs spaced by, say, three intervals, and they are all connected via Or gate 32.3 to a store 33.3. If the starting pulse was not a spurious pulse an output appears from the gate connected to the third counter stage which is gated with the output from flip-flop 14 at 31.1 to set store 33.3. An output C from the store passes via gate 35 to reset all the storage flip-flops. Other stores are provided for 5, 8 and 21 sees. Special gating arrangements are provided for pairs, the first pulse of which is in one counter cycle and the second in the next. The detector overcomes the usual difficulty of such systems arising from spurious pulses which start the counter and normally necessitate waiting for the whole counter cycle to determine whether the pulse was the first of a valid pair. If a valid pair of pulses is received while the counter is at rest, the first starts the counter and sets flip-flop 14 and the second is applied by one of the gates 9 to an appropriate gate, e.g. 31.1 to give a valid pair signal. If a valid pair of pulses is received while the counter is running, having been started by a spurious pulse, the first pulse is stored and gated with the second when it arrives, to give a valid pair signal.

Title: An improved method of producing highly purified ethyl alcohol and an apparatus for carrying out such method
Filed: 1959-02-17
Abstract: <PICT:0900627/III/1> Crude dilute ethyl alcohol is fed by a pipe 1 to a washing tower 2 to which, at a slightly lower level, water is supplied from a rectification column 12, the water having a raised temperature, e.g. 95 DEG -100 DEG C., and a pH value adjusted to between 8 and 12 by addition of alkali.  Volatile resin-forming impurities are thus driven off to a condenser 3, and the dilute alcohol from the foot of the tower 2 is passed by a pipe 9 to the rectification column 12, which is of conventional design, the purified alcohol being withdrawn through a pipe 18.  Vapours evolved from the top of the column 12 are condensed in condenser 13 and returned in part to the column by pipe 14, the remainder passing to tower 2 by way of pipe 15.  A pump 16 delivers water from the base of the column 12 to a point near the top of the tower 2.  The impurities condensed in condenser 3 may be returned in part to the tower 2 by a pipe 4, and the remainder may be passed to a second washing tower 6 to which water is supplied from the column 12 by pipe 17.  The liquid from the foot of the tower 6 may be supplied to the tower 2 by means of a pump 10, and the vapours from tower 6 may be passed to a condenser 7 and thence to a separator 8.  The process is particularly applicable to the refining of ethyl alcohol obtained by the catalytic hydration of ethylene, but may be applied also to ethyl alcohol produced by fermentation.
