Title: Method of feeding and breeding crustaceans
IPC: A01K61/59
Filed: 1970-11-27
Abstract: 1334087 Breeding crustaceans COMPAGNIE GENERALE TRANATLANTIQUE 27 Nov 1970 [12 Dec 1969] 56446/70 Heading A1A A method of rearing and feeding large numbers of decapod crustaceans such Palaemonidae, especially Leander servatus comprises introducing sea water into an artificial rearing pond, adding in the pond certain elements such as Si, P, N to encourage planton development, controlling the conditions of temperature, oxygenation, lighting, salinity and agitation and then introducing into the pond three groups of marine organisms, namely plankton, copepoda and the crustaceans in either egg or initial larval stage, the copepoda thereafter being added to the pond at regular intervals. The plankton are added to the pond from the sea or from a separate pond. Eggs of Artermi salina are then added and hatch to larvae which feed on the plankton. Larvae of the crustaceans are added at or after the time of hatching of the Artemia salina egg and the conditions are such that the crustacean larvae may feed on plankton, the eggs or larvae of Artemia or on the mature Artemia. Further sea water may be added if required and further quantities of Artemia eggs are added at predetermined intervals during the crustaceans' larval life to produce food sufficient for a period equal to the larval period and a further equal period after metamorphosis. The three groups of orgnisms viz plankton, Artemia and crustaceans may be bred in the same or different ponds.

Abstract: 1,181,049. Natural gas liquefaction process. MESSER GRIESHEIM G.m.b.H. 5 Dec., 1968 [20 Dec., 1967]. No. 57848/68. Heading F4P. Cooling, followed by liquefaction and subcooling of compressed natural hydrocarbon gas in feed line 101 is effected in heat-exchangers 102, 103, respectively, and the sub-cooled liquid is then further cooled at 104 and expanded at a valve 107 into a separator 105; exchanger 102 being cooled by passage therethrough of a first multicomponent refrigerant, e.g. a mixture of C 1  to C 4  saturated hydrocarbons in a closed, cycle, exchanger 103 being cooled by a second multicomponent refrigerant, e.g. a mixture of nitrogen, methane and ethane also in a closed cycle and in cascade arrangement with the first refrigeration cycle and the refrigerant of each cycle undergoes only one compression stage and is expanded to above atmospheric pressure. Exchanger 104 is cooled by flash gas from separator 105 which gas also cools exchangers 102, 103. In operation, the first refrigerant is compressed at 109 to about 40 atmosphere liquefied in a water-cooled exchanger 110, further cooled in exchanger 102 in countercurrent heat exchange with itself after expansion at 112 to about 3 atmosphere, and the refrigerant after leaving the warm end of exchanger 102 is returned to the compressor inlet. The second refrigerant is compressed at 114, cooled by water at 115, liquefied in exchanger 102, further cooled in exchanger 103, expanded at a valve 117 and returned through exchangers 103, 102 to the inlet of compressor 114.

IPC: A22C21/06
Filed: 1970-12-07
Abstract: 1306719 Eviscerating fowl GAINESVILLE MACHINE CO Inc 7 Dec 1970 [8 Dec 1969] 57913/70 Heading A2U A method of eviscerating a fowl being conveyed in a predetermined path, comprises causing relative movement between the fowl and an eviscerating tool so that the tool is first inserted into the fowl through an abdominal cut between the viscera and breast bone and then withdrawn therefrom to remove the viscera, there being pivotal movement between the fowl and tool during the process. The fowl may be killed by cutting its jugular vein and the crop may be removed with the viscera by cutting the gullet. The fowl may be defeathered. In one embodiment, the fowl 27 is carried by shackle 14 (as in Specification 1306720) along rail 11. The shackle 14 is associated with eviscerating tool 40 which is maintained in a retracted position with respect to the shackle by spring 36. The arms 33 of shackle 14 are pivotable in bracket 30. During movement of the shackle 14 along the upwardly inclined portion of rail 11 the shackle and fowl are moved upwardly relatively to the tool 40 which is held by means of rails 19 engaging cam 28, the spring 36 being compressed, so that the tool enters the fowl. During insertion the shackle and the head of the fowl are pivoted in opposite directions by means of rail 21 and rails or chains in table 16 respectively. As the shackle is moved along the downwardly inclined portion of the rail 11 the process is reversed, the shackle and fowl's head each being pivoted in a direction opposite to that during insertion. In Fig. 11 (not shown) the eviscerating tool is not carried by the shackle.

Filed: 1973-12-14
Abstract: 1457880 Calculator system TEXAS INSTRUMENTS Inc 14 Dec 1973 [11 June 1973 (3)] 58042/73 Heading G4A A calculator implemented on semi-conductor integrated circuit chips is provided with one or more additional data stores each formed on an integrated circuit chip. The calculator may be as described in UK Specification numbers 1,401,204 and 1,401,265 and the additional data storage chips may be of the kind described in Specification 1,401,203 and U.S. Specification number 3,851,313. Each storage chip may provide ten, sixteen digit registers and has four data input/output leads for receiving address data and for exchanging data with the calculator in the form of BCD digits parallel by bit serial by digit, and control inputs. Accessing an additional data storage chip occupies four instruction cycles. During the first the chip responds to a FLAG control input from the calculator indicating that the data following is address data, any data appearing at the data inputs being otherwise ignored. In the following cycle the first, third, and fourth digits of a sixteen digit word supplied by the calculator designate respectively whether the operation required is input or output (relative to the storage chip) or the clearing of a specified register or registers, the particular register involved, and the particular chip involved, the remaining digits being unused. Each chip has four prewired inputs for comparison with the chip select digit, there being a further input to allow up to 32 chips of additional storage to be addressed. In the third cycle the FLAG control signal is reset and in the fourth sixteen digits of data are transferred between the calculator and the selected register or the selected chip. It is stated that a one digit delay occurs in the calculator and the additional storage chips are arranged to receive data from the calculator and perform a right shift, the last digit being buffered until the right shift has been completed, and to transmit data to the calculator one digit early. Clear operation may involve all registers in all additional storage chips, all registers in a selected chip, or selected registers in a selected chip. Address decoders used to select a register for data output to the calculator are powered only at times within a cycle of the system when they are required in order to reduce the power drain.
