In a furnace for roasting limestone in which a charging shaft 16 feeds material in succession through combustion chambers 10 and 12 over sloping hearths 14 and 18, each chamber has three burners 28, 30 in ports 26 in the vertical wall 24 opposite the hearths, which latter have associated upper, damper controlled apertures 42, 42a feeding flues 43, 45, 45a leading to a recuperator 40, the central burner 30 being regulated separately from the outer burners 28. The recuperator 40 supplies the burners with clean, preheated combustion air. The burner ports 26 widen outwardly all round, but in a modification (Figs. 4 and 5) the burner port side walls are vertical and the lower wall is inclined downwardly. Limestone in the centre region of each hearth tends to travel faster than that in the outer regions thereof and the separate control of central burner 30 enables this to be compensated for.

Title: Method and package for storing and shipping oyster larvae
IPC: A01K63/02
Filed: 1971-09-06
Abstract: 1331356 Storing and shipping marine larvae PACIFIC MARICULTURE Inc 6 Sept 1971 [14 Sept 1970] 41423/71 Heading B8C [Also in Division F4] In a method of storing and shipping oyster larvae such larvae are provided at, or near, the state of metamorphosis, the temperature of the larvae is reduced to a level substantially below the larvae growing temperature to avert metamorphosis and the larvae are stored at the said temperature. Preferably the temperature to which the larvae are reduced is slightly above freezing and, when it is desired to use the larvae, their temperature is raised to cause metamorphosis to commence. When larvae, in a tank of sea water at a temperature of approximately 30‹ C., begin to go through metamorphosis by setting on the wall of the tank they are collected on a screen and rinsed in sterilized cold water having a temperature within the range of slightly above 0‹ C. to 15‹ C. so that metamorphosis is arrested. Apparatus for transporting the larvae comprises a screw-top plastics bottle 11, having a capacity approximately of one litre, and which is completely filled with sea water chilled to a temperature within the range of just above 2‹ C. to 15‹ C. and containing larvae previously chilled. The bottle 11 is placed in a polyurethane chest 16, surrounded by cold cells 21, each comprising an outer envelope 23 of plastics containing a freezable liquid, and is covered with a burlap sheet 26. In an alternative arrangement, Fig. 2, oyster larvae are strained from a body of sea water at larvae growing temperature, and are placed on a cotton cloth 31 saturated with sea water and maintained damp by wick-action so that the larvae are reduced to within the said temperature range which prevents metamorphosis. The cloth 31 is then gathered together, Fig. 4, to form a bag which is closed by a rubber band 32. The bag, containing the larvae 13, is then placed in a bottle 11, a wick 33, extending from a test tube 36 containing sea water 36 into the cloth bag to contact the larvae, serving to maintain the relative humidity of the atmosphere in the bag very close to 100%. A non-hygroscopic film 37, for example of plastics, is packed into the bottle 11, which is then packed, as before, in a chest 16.

The rolling mill of Specification 1,217,273 is modified so that it may be employed as a paperhandling machine, the summation devices 22--26 being cascaded in opposite directions from a central controlling roll unit 14 and being supplied with individually adjustable control voltages from potentiometers 28--32 which are energized with a ramp voltage obtained from an integrating amplifier 27 feeding further amplifiers 33, 34. It is explained that this arrangement enables minor adjustments of the speeds of the various driving motors for the roll units 11, 12, 13, 15, 16 to be made at the potentiometers 28--32, thus obviating the need for adjustment of the potentiometers at the outputs of the summation devices. Members 17--21 may measure the position or tension of the paper loops. The ramp voltage becomes constant after its initial period of increase.

The current sources Q7, Q8 and Q9 are controlled to feed identical currents to the respective circuits and the load impedances R1, R2, R5 and R8 are selected so that the output levels of the circuits are the same. Fig. 5 shows a matrix four channel decoder which is fed with the signals LT and RT and including a first signal composing stage having transistors Q1 and Q2, which are parallel connected, in series with a bypassed constant current supply to provide phase inverted LT and RT signals across the respective loads R1 and R2, each transistor providing a gain of #2. A similar circuit including transistors Q3 and Q4 has a common load resistor R5 and gains of 1 so that the output signal is - (LT+RT) while a differential amplifier Q5, Q6 provides an output LT - RT. The four signals from the first signal composing stage are fed through respective gain control stages each having a constant current load circuit Q14, Q16, Q18 or Q20 for a respective amplifying transistor Q10, Q11, Q12, or Q13, and an output transistor Q15, Q17, Q19 or Q21, with negative feedback controlled by variable resistors Rr, Rl, Rb, and Rf. The resulting gain controlled signals are fed to a second composing circuit using differential amplifiers Q22, Q23; Q26, Q27; and Q28, Q29 and a summing circuit Q24, Q25, to provide output signals The circuit may be constructed as a monolithic integrated circuit with the variable resistors Rr, Rl, Rb and Rf formed by the drain source conductance of MOS type f.e.t.'s. In a modification of part of one of the signal composing circuits f.e.t.'s are used instead of bipolar transistors Fig. 3 (not shown).

Abstract: 1371332 Clutch control; friction clutches; reverse gearing SELF CHANGING GEARS Ltd 30 Nov 1971 [1 Sept 1970] 41710/70 Headings F2C, F2D and F2L A clutch control for a marine forward-reverse gear comprises a valve 10 which regulates the pressure of liquid supplied to the engaging servo 17 of a friction clutch 4, the valve 10 having a valve spool 11 and a manually controlled piston 12 which, in the position shown, holds the valve spool 11 in a position in which it admits liquid at maximum pressure to the servo 17. When the piston 12 is moved right the valve spool 11 is resiliently biased to the left by a spring 14 to meter pressure liquid to the servo 17 at a reduced pressure. The reduced pressure is determined by the position of the piston 12. The reduced clutch engaging pressure acts on a small clutch engaging servo-piston 18b alone whilst the maximum clutch engaging pressure opens a valve 20 to additionally supply clutch engaging pressure to a large servo-piston 18a. The clutch engaging pressure is supplied by an engine driven pump 1 through a forward-reverse selector valve 2. When reduced clutch engaging pressure is supplied to the servo 17 for slipping engagement of the clutch 4, the supply pressure opens a valve 23 to supply lubricating and cooling liquid through a line 24 to the periphery of the clutch from whence it flows through grooves in the clutch plate 19 to an exhaust duct 7. When the clutch 4 is fully engaged a pump 29 driven by the propellor shaft supplies cooling and lubricating liquid through the duet 7 to the clutch 4, the liquid being exhausted through the valve 20. The pump 29 normally supplies lubricating liquid additionally to the reverse gear through ducts 6. When the selector valve 2 is in a neutral position the pump 1 supplies lubricating fluid to the reverse gear. Pressure relief valves 8, 9 are provided.

Cargo containers 30, Fig. 1, are handled simultaneously by a pair of spreaders B which are adjustably spaced apart by links C. Cables 20 are arranged so that the containers tend to swing towards each other. The links C comprise levers 78, Fig. 3, pivoted at 80 to slides 68 which are moved by rams 62 to vary the spacing between the spreaders. The levers 78 have guide projections, which co-operate with grooves 86 on the adjacent spreader, and shoulders 89 which transmit the thrust. Pivots 80 allow the levers to swing upwards if a support at the loading station passes between the spreaders before the links have been automatically withdrawn by sensing means99, Fig. 6 (not shown), on the spreader. A shear pin 102, Fig. 5, allows the lever 78 to swing downwards if an obstruction 92<SP>1</SP> is struck as the spreaders are being raised. The two winding motors 14, Fig. 1, may either be operated separately or interconnected by a clutch 17 for synchronous operation of the winding drums 16. The spreaders are suspended from a carriage 24 which runs on rails 28.
