Patent NL-8103265-A (NL)
Title: AC=DC power converter using microprocessor - controlling firing of thyristor bridge circuit supplying power to output rectifier circuit via HF transformer
IPC: H02M3/315
Filed: 1981-07-08
Abstract: This industrial converter uses a h.f. thyristor bridge coupled by a transformer to a rectifying and filtering output circuit. The firing timing of the thyristors is controlled by a microprocessor fed with signals representing the following data: input voltage characteristics, output voltage, polarity and the currents drawn b the diodes which are in anti-parallel with the thyristors. The circuit has a high conversion efficiency and a power facto approaching unity. The circuit between the balance points of the thyristor bridge consists of a series-resonant circuit in series with the primary of the trasforme. The microprocessor memory holds a tble of input voltages versus delay tifiringes, used in timing the thyristor pulses.

Patent PT-66197-A (PT)
Title: Portable mill for cereals fodder and the like
Inventor: VERCELLA P
IPC: B02C18/06
Filed: 1977-02-16
Abstract: The mill comprises a circular frame, a discharge chute with a perforated grid arranged above the outlet; a wall is placed above and around this opening so as to define a grinding chamber between the lower face of the base plate and the hood. A motor is mounted on the base plate with its shaft vertical; this penetrates into the grinding chamber and carries two cutting blades. The material to be ground is poured into the charging hopper with the motor running at a speed of 25,000 rpm. The grains descend through the pipes to the grinding chamber where they are subjected to the impacts of the rotating blades co-operating with the grid; some of the grains too large to pass the grid are thrown against the walls of the chamber and are pushed back until they are again struck by the blades until they are sufficiently small to pass through the meshes of the grid into the discharge chute. The dwell time in the grinding chamber is extremely short, because of the high speed of the cutters, so the temperature of the matl. does not rise very much; certain biochemical properties, therefore are not deteriorated as with conventional mills. The mill is strongly constructed and can be transported and installed without the need for skilled labour.
Patent PT-70760-A (PT)
Title: Liquid metering unit
Inventor: STIRLING WILLIAM
IPC: G05D/
Filed: 1980-01-31
Abstract: In a continuous blending process, an additive is fed from a stock tank alternately into one or other of two reservoirs connected in parallel. As one reservoir is being charged the other is being discharged. The mass of liq. is continuously monitored in each reservoir using sensors which emit signals proportional to liq. mass for conversion into a flow signal proportional to the mass flow rate. The rate is compared with a desired mass flow rate and the setting of a flow control valve is adjusted accordingly to bring the flow rate to a desired value. Used for the control of continuous liq. blending operations, e.g. gasoline blending, in which a liq. additive e.g. tetraethyl Pb, is fed into a continuously flowing stream.

Filed: 1988-12-01
Abstract: The device for measuring the density or viscosity of a fluid flowing in a closed passage (2) includes a rotor (5) whose speed of rotation is directly dependent on the rate of flow of the fluid. The rotor (5) is connected to an activatable and deactivatable brake means (13, 14, 15) which has an adjustable braking force. Depending on the setting of the brake means, the brake is operative to cause a greater or smaller lag in the rotary speed of the rotor (5) in relation to an unbraked rotor (5) or a rotor braked with a smaller force. The measuring means (9, 10, 11, 12) is operative to determine the resultant different rotational speeds of the rotor (5), and the difference in these speeds is a measurement of the viscosity and/or density of the fluid.
