Abstract: The present invention relates to a method of automatically watering plants arranged on a substrate to which liquid can be supplied by means of at least one valved supply conduit (37). At least one of the substrates is arranged in a receptacle communicating with a trough (3). The liquid supply takes place cyclically at timed intervals and in excess quantities. The quantity of liquid flowing from the trough (3) during a watering cycle is measured, while the time during which the valves remain open, after a "full" signal has been received is controlled in dependence on the measured excess of liquid flowing from the trough (3) during one or more of the preceding cycles. The present invention further relates to an apparatus for performing the above method. The apparatus comprises a measuring means (4) connected to the measuring opening (2), which means (4) is coupled to a control device (6) for controlling the valves depending on the measured quantities of fluid flowing through the opening (2).

Abstract: A synthetic plastic bag for containing liquids, e.g., urine, has a plastic outlet tube (10). It is manufactured by a first step of seam welding the tube (10) between two superposed bag walls. In a subsequent step, an encircling sleeve (20) is slid over the tube (10) to a position where it contains within it the portions of the bag walls on either side of the tube (10). Thirdly, this sleeve (20) is compressed onto the tube (10) by a crimping operation conducted with the crimping force applied in a direction radially of the tube (10) but at substantially right angles to the plane in which the bag walls lie. 
     Alternatively, the tube (10) may be molded in place over the end of the bag.

Abstract: The invention relates to an energy absorber which uses the plastic deformation of metal strips. 
     The strip (5,6) is wound, while hot, into a spiral on a pin (3,4) through at least one and a quarter turns and has a thickness of at least half that of the pin. 
     When the outer end (5a, 6a) of the strip is pulled so as to tend to unwind the strip (5,6) from the pin (3,4),the strip deforms plastically with absorption of energy in its movement from its initial wound condition to a final substantially straight condition. The deformation of the strip from the curved condition to the straight condition occurs through progressively-decreasing radii of curvature, which enables the energy absorption resulting from the plastic deformation to be optimised.

Abstract: Afin de mesurer la concentration d'un analyte dans un échantillon liquide, l'échantillon est mis en contact avec une molécule réceptrice ayant des sites de liaison de l'analyte et marquée par un premier marqueur de sorte que l'analyte occupe une partie des sites de liaison de la molécule réceptrice, l'échantillon étant mis en contact avec une quantité si réduite de molécules réceptrices, compte tenu de sa constante d'affinité avec l'analyte, que seule une partie insignifiante de l'analyte se lie aux cellules réceptrices. Les molécules réceptrices à sites de liaison en partie occupés sont titrées en retour par une technique de titrage en retour selon un système comprenant un deuxième marqueur différent du premier et la puissance relative des signaux produits par les deux marqueurs est mesurée pour donner une valeur représentative de l'occupation partielle des sites de liaison de la molécule réceptrice par l'analyte. Cette valeur est comparée avec une ou plusieurs valeurs correspondantes obtenues de la même façon à partir d'échantillons liquides standard ayant une concentration connue d'analyte. Un dispositif d'analyse utile pour appliquer ce procédé comprend un substrat solide étendu (20) portant en une pluralité d'emplacements espacés (21) une pluralité de molécules réceptrices diverses (22) ayant chacune des sites de liaison d'un analyte, la molécule réceptrice à n'importe quel emplacement ayant des sites de liaison spécifiques à un analyte différent des analytes correspondant aux sites de liaison spécifiques des autres molécules réceptrices situées aux autres emplacemnts. Chaque molécule réceptrice peut être facultativement marquée. Ce dispositif peut faire partie d'un kit d'application du procédé.

Abstract: The stuffing ram (2) of the feeding cylinder (1) of an injection-moulding machine for polyester processing has a venting opening (11) arranged parallel to its longitudinal axis. The venting opening (11) is assigned a coaxial closing ram (13), which can be introduced into the venting opening (11) and closes the latter during the stuffing operation. The venting opening (11) is closed when most of the air in the feeding cylinder (1) has escaped through the venting opening (11). Controlling of the closing ram (13) for closing and releasing the venting opening (11) is performed as a function of the filling state and degree of filling either pressure-dependently or time-dependently. This ensures effective venting of the feeding cylinder (1), and consequently satisfactory processing of the polyester compound (4) and an undisturbed process at all times, even with varying filling state. <IMAGE>

Abstract: A rotary engine has a substantially trochoidal-shaped housing cavity (24) in which a rotor planetates. The cooling systems for the engine directs coolant through the housing along a path consisting of series-connected groups of passages. Coolant enters near the engine air intake port (34), passes downwardly and axially through the cooler regions (62) of the engine, then passes upwardly and axially through the hotter regions (74) near the spark plug. By first flowing through the coolest regions, coolant pressure is reduced, thus reducing the saturation temperature of the coolant and thereby enhancing the nucleate boiling heat transfer mechanism which predominates in the high heat flux region of the engine during high power level operation. The coolant flows in the opposite direction to rotor rotation, and flows downwardly through the coolest regions and upwardly through the hottest regions, the coolant inlet (36) and outlet (38) being together at the top of the housing.

Abstract: A frequency difference detector (FDD) of a balanced quadricorrelator type comprises a front end formed by quadrature related first and second mixers (12, 14) in which an input signal is mixed down to base band. After the in-band signal components have been selected by low pass filter (18, 20) the signals VI1, VQ1 are applied to third and fourth mixers (30, 32). In applying these signals VI1 and VQ1, they are differentiated by one or more orders and applied to respective first inputs of the third and fourth mixers (30, 32) and to respective second inputs of the fourth and third mixers. When differentiating the signals VI1 and VQ1, it is necessary that there is one order of difference between the signals at the first and second inputs of each of the third and fourth mixers (30, 32). The outputs of the third and fourth mixers are applied to a subtracting circuit (38) which provides a frequency difference output signal. 
     An a.g.c. circuit is disclosed. 
     The FDD disclosed can form part of an FM demodulator for a carrier modulated receiver.

Abstract: A vehicle braking apparatus (10) having a service braking section (12) and a wheel lock control (ABS) section (14). Under certain conditions the wheel lock control section may not be able to generate sufficient pressure to operate the vehicle wheel brakes (30) when the master cylinder (20) output pressure has been isolated from the wheel brake. When such conditions occur, the displacement piston (106) of the ABS section moves to open a check valve (122) which connects master cylinder output pressure to the vehicle wheel brake even though the ABS section has isolated it from the wheel brake. The opening of the check valve effectively returns the vehicle braking apparatus to service braking until the vehicle operator releases the vehicle braking apparatus.
