Abstract: A passive dosing dispenser for issuing, for example, a predetermined volume of a toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing. A preferred dispenser (20) comprises a product chamber (69) for containing a quantity of a solid type product (21) which can be dissolved in water to form a toilet tank additive product solution, a reservoir (65) for containing a quantity of said solution in fluid communication with said product chamber (69), an inlevdischarge conduit (80) having its lowermost end in fluid communication with said reservoir (65) and its uppermost end in fluid communication with a syphon tube (44), an air trap (81) disposed adjacent said inlet/discharge conduit (80) for isolating said product solution from the toilet tank water in said syphon tube (44) during quiescent periods, and an air vent (83) in fluid communication with said reservoir (65) and product chamber (69). In operation, while the water in the toilet tank is receding from about the dispenser (20), a predetermined quantity of said product solution is syphoned from said reservoir (65) through the inlet/discharge conduit (80) and is dispensed through the syphon tube (44). The dispenser provides a pair of air-locks when immersed in a full toilet tank which air-locks isolate the product and product solution from toilet tank water which surrounds the dispenser during quiescent periods.

Abstract: A fluid pump or motor (10,110) has a stationary cylinder block (28), pistons (24), and a swash plate type mechanism (36) to link reciprocation of the pistons with rotation of a shaft (46,146). A valve plate (66) rotates with the shaft (46,146), and controls the flow of fluid between low and high pressure connections (18, 16; 22, 20) and ports (60) in the cylinder block (28), leading to the cylinder bores (26). The valve plate (66) is biased against the cylinder block (28) by an axially-movable but non-rotating balancing member (80), which contains balancing pistons (88), supplied with pressure from the ports (76, 78) in the valve plate (66) through passages (86). The reaction from the pistons (88) biases the member (80) against the valve plate (66). The balancing member (80) is also biased by the pressure from the high-pressure connection (16; 20) acting on a shoulder (96).

Abstract: The invention relates to static inverters of the type with a symmetric self-oscillator, which are able to transform a high-voltage direct current into an alternating current having specified frequency and specified power. The self-oscillator includes two switching means configured as amplifiers with a common electrode. The DC supply is provided from the mains current rectified by a diode bridge charging a reservoir capacitor. One of the poles of the supply is connected to the self-oscillator via a voltage limiting circuit which permits modulation of the power applied to the load as a function of ambient light. A circuit for phase-shift correction is inserted between the mains and the rectifier. The device is capable of supplying fluorescent tubes whilst minimising energy consumption. <IMAGE>

Abstract: It is also intended to take into consideration the RF paths between mobile transmitting/receiving devices (M) and relay stations (R) in the delay compensation. For this purpose, the mobile transmitting/receiving set (M) transmits control and calibration signals which are compared in time in a comparison device (VER) in the base station (Z). On the basis of the result of the comparison , delay elements (LZA) are automatically adjusted in the transmitting paths (SZ). When the base station (Z) sets up a connection, the relay sations in the RS1 circuit are first keyed by the base station (Z) and control and calibration signals are sent over the transmitting paths (SZ), are recieved via the recieving paths (EZ) and are compared in time in the comparison device (VER), and the delay elements (LZA) are set. This setting can also be locked as basic setting of the delay sections (LZA). When dialling lines are used as modulation feeders, first the transmitting paths (SZ) and then the receiving paths (EZ) must be calibrated (FIG. 1). <IMAGE>

IPC: A23C19/028
Filed: 1981-12-01
Abstract: A process for an efficient production of cheese or cheese base containing substantially all the casein and whey proteins which were originally present in the milk comprising four phases: (1) selective concentration of milk to form a concentrate; (2) increasing the ionic strength of the concentrate so as to maintain it in the liquid phase during fermenting; (3) fermenting the concentrate; and (4) removing water from the fermented concentrate to produce cheese or cheese base containing substantially all the casein and whey proteins originally present in the milk. The concentrates and fermented concentrates are unique intermediate products in that they do not coagulate during processing even at low pH's. The process permits an efficient evaporation of water from the fermented concentrate that is maintained in the liquid state. The process also avoids the possibility of losing whey proteins by totally eliminating syneresis.
