Patent FR-2231958-A1 (FR)
Title: Primary or secondary light source - has device for determination of their colour components or coordinates in terms of international standard X-Y-Z system
IPC: G01J3/51
Filed: 1974-05-24
Abstract: The device comprises a sensor system consisting of three colour filters and one photocell which can carry out measurements in the internationally standardised (CIE), X, Y, Z colour coordinate system with good accuracy. The system converts, using linear transformation resistor network and summators, colour components values determined by instrument systems into corrected component values which better correspond to values measured in the international system. The colour coordinates are derived from the corrected values by a signal processing unit comprising an operational amplifier in a summating cct. and a digital ratiometer.

Title: Flexible container sealing process - uses cap with vent and distorting membrane inside and inert gas
IPC: B65D79/00
Filed: 1974-05-31
Abstract: The process is particularly for bottles of flexible plastic, which are filled with warm fluid. A cap (3) is used, having a vent (6) in the top also an elastic membrane (5) on the inside. The latter distorts towards the inside of the bottle under the effect of cooling, and before finally sealing the vent the air in the intervening space between membrane and cap is flushed out and replaced by inert gas. The membrane can be of material permeable to gas but not liquid. The process is particularly for liquid foodstuffs liable to ferment, and avoids bottle distortion after filling as they cool.

Title: Braking appts using eddy currents - is for railway brakes working in combination with pneumatic brakes
IPC: B60L7/00
Filed: 1974-10-21
Abstract: The apparatus consists of a brake body and a device to measure the braking force. Existing systems are based on working on a theoretical value of braking force, but the eddy current brake may be adapted to work in conjunction with a pneumatic brake. The two brakes are dependent upon each other and the total braking force is controlled. A generator is connected to a system of controls, and is connected to the eddy current brake at a certain speed. Some of the measuring devices are sensitive inductances and others are capacitances and piezo-electric transducers. The control system consists of a sophisticated electronic computer. At low speed, the apparatus achieves gradual transition between eddy current braking and pneumatic braking using ordinary brake blocks.

Title: Stripper assembly for holding meat after injection of pickling brine - while the injection needles are withdrawn
Inventor: LANGEN BERNARDUS GERTRUDA
IPC: A23B4/28
Filed: 1975-06-17
Abstract: In a stripper device for use in a brine pickle injector, for retaining the meat during the return motion of the injection needles and for releasing the needles from the meat, of the known type comprising a stripper beam and a support yoke for supporting and guiding the beam during its vertical movement, means are provided for the stripper beam to rest freely movable on the meat during the injection stroke of the needles and to be fixed at the end of this stroke in its position at that instant. In contrast to the known brine injection systems in which the stripper beam is fixed either directly or by strong springs, the injection does not have to be made against steadily increasing pressure due to swelling of the meat as it takes up the pickling brine or complex adjusting equipment supplied to prevent this. Uniform impregnation with brine is thus assured without loss of brine.

IPC: G05D23/24
Filed: 1976-06-15
Abstract: The electronic temp. regulator is in the form of a Wheatstone bridge. In one branch of the bridge is a thermistor. This thermistor measures the temp. to be regulated. In another branch of the bridge is an adjustable resistance used to set the required temp. In the diagonal of the bridge is a detector used to selectively drive control stages of a regulating element.

The bases of these transistors are respectively connected to the ends of the bridge diagonals. The collector-emitter circuits are inserted in shunt between the negative pole of the source and two control lines. Each of these control lines connects the positive pole of the source to an amplification stage. This amplification stage is connected to a terminal of one of the control stages of the regulating element. These stages include a common terminal connected to the positive pole of the source.
