Abstract: Weighbridge consisting at least partially of cast concrete portions, and method of producing such a bridge. With the object of increasing the accuracy of a weighbridge, of facilitating and cheapening the production of a weighbridge, it is proposed according to the present invention that the bridge (1) should be disposed resting against two beams (5) which are disposed along the long sides of the bridge and supported by transmitter members (6), that at least two transverse beams (7) are disposed secured between the longitudinal beams (5) of the bridge, preferably at the short sides of the bridge, that the cast portions of the bridge are surrounded by an edge lining (3) preferably of sheet metal bearing downwards against the tops of the beams (5, 7), and that the cast portions preferably comprise a corrugated or profiled bottom metal sheet (12) resting substantially against the longitudinal beams of the bridge. As a result of the invention, it becomes possible to cast the weighbridge on site above the longitudinal beams, and the mould formed by the edge lining, beams and metal sheets does not have to be removed after the cast concrete has set.

Abstract: A burner having an air intake at atmospheric pressure, a gas (fuel) supply line and a combustion chamber in which gas from the latter line burns in the presence of atmospheric air drawn in from the intake, is provided with a swingable or rotatable flap-type valve member which controls the volume rate of flow of the air to the combustion site. According to the invention, the position of the valve member is controlled by a parameter generated by the air stream and in response to the pressure in the gas supply line to maintain the air factor (ratio of air to gas) substantially constant. To this end a membrane type pressure detector responds to the pressure in the gas supply line and is connected by a mechanical force transmission mechanism to the flap or other valve element.

Abstract: Un compresseur de brouillard d'huile a rotor excentrique a aube coulissante possede une unite rotor-stator (6, 4) dans une enveloppe de compresseur (2). En fonctionnement, de l'huile est injectee dans l'espace de compression dans le stator puis extraite a partir de l'air comprime en deux etages. Le premier etage est constitue par un premier ecran de collision (10) situe autour du stator et le second etage par deux elements de coalescence (16) dans une enveloppe de separation separee (14). L'huile combinee par coalescence qui s'accumule dans l'enveloppe de separation retourne a l'unite rotor-stator pour etre reutilisee sous l'action d'une pression differentielle produite par le compresseur par l'intermediaire d'un passage de retour d'huile (30, 32, 36, 44) comprenant un orifice de restriction (42). Le passage (44) communique avec l'espace de compression en un point ou la pression est sensiblement superieure a la pression atmospherique, et il ne communique pas avec l'entree du compresseur. La pression differentielle du retour d'huile est par consequent plus petite que la normale, ce qui permet a l'orifice (42) d'etre plus grand que normal, reduisant ainsi sa tendance a l'encrassement.

Abstract: A logic array (10) includes a matrix logical elements (13) located at the intersections of a plurality of input (16) and output lines (17). Due to the nature of the array structure, more than one output line (17) may be activated by a given digital bit pattern placed on the input lines (16). In testing the array, the lack of a one-to-one correspondence makes it difficult to determine if the personalization associated with a given output line is proper. 
     The output line interference problem is solved by providing a deletion control line (28) which may be selectively connected to any combination of output lines (17) to thereby disable the connected output lines. Thus, a given output line may be personalized, tested and then disabled, to preclude interference between the tested output line and the remainder of the lines to be tested. Moreover, since the logic array (10) is tested one line at a time, provision can be made for substituting spare output lines (17 E, F) for defective output lines, thereby rendering a defective array usable.

Abstract: A phase-locked loop circuit is disclosed in which the output of a controllable oscillator 50 is fed back to a phase comparator circuit receiving a reference phase input signal. The comparator circuit provides a phase error signal V o  and this error signal is used to pull the oscillator into phase with the input signal. The control signal (I fr - I gain ) applied to the oscillator is produced at a node 66 by two circuits 56,64. The circuit 56 comprises current mirror circuits Q1, Q2 in which the current magnitude is set by a resistor R fr.  The magnitude of I fr  sets the free running frequency of the oscillator 50. The circuit 64 comprises current mirror circuits Q3, 04 in which the current magnitude is set by the magnitude of the error signal V o  and of the resistor R gain.  The magnitude of I gain  determines the frequency/phase shift of the oscillator.
