Title: Loading hopper with conveyor bottom - has conveyor slats overlapping between end rollers to form closed track
IPC: B65G65/42
Filed: 1979-11-23
Abstract: The hopper is particularly for potatoes etc. and has two sides and a base, the latter formed by an endless conveyor running round rollers. The latter comprises transverse slats mounted at the ends on roller chains engaged by sprockets at the roller ends.

Title: Milk-meter with measuring cups - each having electrode connected to counter and with float compensating for air received in milk
IPC: G01F15/02
Filed: 1980-04-03
Abstract: The milkmeter has a measuring part (1) in which there are measuring cups (4) each having an electrode (13) at its bottom (12), the cups being arranged in three series each of three cups (7,8,9). A milk supply chute (10) is pivotable around a transverse axis (11) to supply milk to the cup on the right of the first series (7), or if the chute is pivoted about its axis to the cup on the left of the third series (9). The cups have common adjacent walls of which the upper edge is lower than the other walls of the cup, allowing milk to overflow from one cup to the next to fill the cups of the first two series (7,8). As soon as milk reaches the electrode in the cup bottom a signal is sent to a counter. Once a signal is received from the right most cup of the third series (9), a further signal is sent to pivot the chute about its axis. Simultaneously the cups of the first and second series are tilted to pour milk from them down the spout (3).. The meter is accurate and compensates for air received in milk. In addition, if only one cup is used in each series a compact meter os achieved.

Abstract: PCT No. PCT/EP81/00050 Sec. 371 Date Jan. 15, 1982 Sec. 102(e) Date Jan. 15, 1982 PCT Filed May 18, 1981.The present invention relates to a method, as well as to a system for carrying out said method, for dehairing slaughtered livestock. A carcass following a warm water treatment is roughly dehaired by means of beating and scraping tools while simultaneously being rotated around its longitudinal axis. Then fine hairs are removed using burner means while still rotating the carcass. A special feature of the invention involves the removal of fine hairs over the whole length of the carcass using burners acting on various zones of the carcass with differences in operating time and/or intensity. In the system according to the invention, differential burner action may be achieved using pivotable burners or reciprocating burners. Alternatively, differential burner action may be achieved using fixed burners having different flame intensities or operating times.

Patent NL-8702256-A (NL)
IPC: F02M21/02
Filed: 1987-09-22
Abstract: A regulating device is concerned for a venturi-type gas carburettor (1), in particular for use with internal conbustion engines. It is aimed to reduce breathing-losses due to the flow resistance of the usually narrow venturi throat (10) and meanwhile improve the control of the gas-air mixture strength produced by the carburettor. This is done by using a wider venturi throat and transmitting, apart from a first known signal (15) from the venturi-annular-ring chamber (11), a second stronger signal (51) to the gas-pressure regulator (20), derived from the very venturi throat by means of a probe (52) projecting into it. Both signals are combined in an adjustable pneumatic potentiometer (50) before the resultant signal (53) is fed to the pressure regulator. By adjusting the potentiometer (50) as function of the engine-main throttle (6) position (torque delivered by engine), enrichment and/or enleanment of the gas-air mixture strength can be adjusted - f.i. to control lean-burn combustion at higher loads and enrichment at lower loads. The same principle can be applied to improve starting, and low load operation. The device makes easy adjustment possible for existing engines, for different engine types and brands, for different fuel-gases, a.s.o., and is of small size.

Title: Removing brine from sea-water - using conveyor belt after freezing and crushing on strainer belt to allow brine to escape
IPC: C02F1/22
Filed: 1991-04-03
Abstract: Brine is removed from seawater by freezing, only the clean water molecules freezing together into clean ice. At the same time the brine is enclosed by the ice crystals.
