Title: Hive, which can be subdivided for one or more bee colonies, having standardised elements which can be removed and fitted into one another
IPC: A01K47/00
Filed: 1986-03-18
Abstract: The invention relates to a hive, which can be subdivided, enabling the bee-keeper to manage his hive according to extensive traditional methods by keeping the super hives already acquired, or according to intensive methods based on the cohabitation of several colonies. This hive consists of super hives 1, of bases 2, which can be placed anywhere in the stack of super hives, of platforms 3, which are all identical and can slide with respect to the front and the rear of the base 2, of movable flaps 4 enabling the platforms 3 to fulfil their respective functions, of removable doors 5 which are all identical and ensure closing and opening of the bases 2. One single type of feeder ensures feeding of the colonies from the top and the bottom, and their ventilation. A pollen trap can be accommodated in the two bases 2 laid on top of one another at the base of the hive.

Title: Method of using a charge-transfer photosensitive matrix and photosensitive matrix thus used
Inventor: EOUZAN JEAN-YVES
IPC: H04N5/347
Filed: 1986-04-25
Abstract: The invention relates to the field of charge-transfer photosensitive matrices which are associated with a read register and with a control circuit, which is able to deliver control signals to the matrix and to the register so as to provide for the reading of the matrix. The invention consists in modifying the control signals providing for standard operation of the matrix 1 and of the register 2 in order to reduce the time required for reading the matrix, either by adding up the information contained in adjacent points of the matrix, or by avoiding reading some of these points, or by combining both methods. In the embodiment of figure 6, the number of readings of the register 2 is reduced by reading the rows in groups of M rows. The number of horizontal transfers effected during each reading of the register 2 is also reduced by arranging a mask 3 over a few columns of the matrix, namely those furthest from the output S of the register 2. Thus, each reading of the register requires only N pulses enabling the N columns of the matrix which are not masked to be read. Application to row-transfer, frame-transfer and single-frame photosensitive devices.

Title: Anti-yaw device for road-going trailers, particularly for touring caravans
IPC: B60D1/32
Filed: 1988-05-03
Abstract: This device 5 is intended to equip road-going hitches consisting of a towing vehicle 1 and a trailer 2, particularly a caravan. A cable 6 is anchored on one side at the rear of the towing vehicle 7, and it passes over a return pulley 8 carried by the front of the trailer 2, before winding round a pulley belonging to a winding-up and braking assembly 9 mounted on the trailer 2 or on its hitching draw bar 3. The pulley is unilaterally rotationally connected by a free wheel to a brake which retards its rotation in the direction corresponding to the increase in the distance between the anchoring point 7 and the pulley 8 for returning the cable 6. A return spring acts on the pulley in the direction of winding up the cable 6. The device exerts a "unilateral" action which prevents any amplification of the yaw movement of the trailer 2 when this movement starts.

Abstract: Equipment for controlling output parameters of a submarine acoustic wave emitter (10) towed by a vessel (20), comprising at least one receptor (40) towed by said vessel along with the transmitter, the acoustic signal received by the receptor being subsequently compared with the signal produced by the transmitter. The receptor according to the present invention is towed behind the transmitter and at a distance therefrom generally equal to that separating the transmitter from a point (41) situated in the perpendicularity of the vessel, or from another reference point for controlling said transmission parameters. The signal received by the receptor can in particular be used to regulate the transmission level of the transmitter so that the acoustical level produced by the transmitter in the perpendicularity of the vessel or in said reference point is maintained below a predetermined limit.
