Abstract: Methods and apparatus for measuring electrical conductivity particularly but not solely for use in detecting mastitis in individual quarters of a cow's udder employ the cyclical charge and discharge of a capacitor (Cl) through liquid in a conductivity cell (9), the cycle reversing on the potential applied to the capacitor (C1) reading a high reference potential and a low reference potential by applying the reference potentials to terminals (10, 15) or sensing leads (32, 33) of electronic devices (VC1, VC2) or (31) to cause operation of switches (SW1, SW2) or (S1, S2) so that the variations in frequency are indications of conductivity of the cell (9). In one modification a reference conductance (30) is included in the circuit during charging of the capacitor (31) and the rate of the time periods of the cycle gives an indication of the conductance of the cell (9) in terms of the reference conductance (30).

Abstract: A process is described for preparing compositions comprising ethylene copolymers, such as ethylene-acrylate or ethylene-vinyl acetate copolymers, and compatible liquid hydrocarbons which act as inexpensive plasticizers or extenders, the process enabling large quantities of inert, e.g. inorganic fillers to be incorporated more simply than previously proposed processes. The hydrocarbon is compatible if it satisfies the test that there is no observable exudation of hydrocarbon from the copolymer when 50 g. of powdered copolymer are mixed with a quantity of hydrocarbon in a metal dish which is first heated to 120°C. to fuse the copolymer, second cooled and held at a temperature of -20°C. for 18 hours, and third warmed to room temperature. The compositions may be prepared either in the form of free-flowing powders or aqueous dispersions both of which are described and both of which have advantages when used in described situations as hot melt adhesives or coating compositions, especially for carpet backing techniques.

Abstract: Single or double-leaflet heart valves (11) having improved flow (19) through the orifice defined by an annular valve (13) body include a pair of leaflets (15) which may be arcuate or flat in cross section. Guides (35) protrude oppositely from the leaflets and are received in complementary depressions (21) in the interior wall surface preferably of a pair of standards (23) which extend downstream from the annular valve body at generally diametrically opposite locations. The depressions (21) are preferably elongated so that, as the leaflets (15) pivot between the open and closed positions, the guides (35) move from one end of the elongated depressions (21) to the other. Eccentric pivot axes provide for quick response of the leaflets, and the location of the depressions (21) in the standards (23) moves the leaflets (15) out of the annular valve body, reducing resistance to the free flow of blood therethrough. The leaflet (15) valve members are preferably arcuate in cross section and may be essentially a portion of the wall of a circular tube.

Abstract: Un circuit a charge divisee (44) sert a porter une charge a haute vitesse (72) et une charge a faible vitesse (74) au meme etat logique en reponse a un ou plusieurs signaux d'entree. Un signal d'entree est applique aux terminaux de portes des transistors de refoulement (48, 50, 52). L'inverse du signal d'entree est applique aux terminaux de portes des transistors de remontage (64, 66). La charge a haute vitesse (72) est connectee entre le transistor de remontage (64) et le transistor de refoulement (50) et la charge a faible vitesse (74) est connectee entre le transistor de remontage (66) et le transistor de refoulement (52). Lorsque le signal d'entree au point nodal d'entree (46) est porte d'un etat de tension a un autre, les charges (92, 74) sont transmises a des vitesses differentes en fonction de la capacitance et de l'impedance de la charge et des dimensions des transistors de remontage (64, 66) et des transistors de refoulement (50, 52). Les charges (72, 74) sont transmises independamment de maniere a pouvoir utiliser des transistors de remontage et de refoulement beaucoup plus petits a la place d'un transistor unique de remontage et d'un transistor unique de refoulement qui devraient autrement posseder des dimensions beaucoup plus grandes afin de satisfaire aux exigences de vitesse de la charge a vitesse elevee (72) et de charger la capacitance elevee de la charge a faible vitesse (74). La consommation de puissance se trouve en outre sensiblement reduite a la suite de la reduction de la surface des transistors.
