Title: Automatic shaping device for foodstuff pastes - e.g. pomme dauphine prior to deep frying
IPC: A22C7/00
Filed: 1972-11-07
Abstract: Device of a plate which can be prevented from rotating when placed over a recipient for the shaped paste. The plate is perforated with holes corresponding to the desired size of the prods. The plate co-operates with a rotary blade which is fixed to an axle; one end goes through a bearing in the plate and the other carries a handle at the top of the cranked portion of the axle. A knife cuts off the extruded pieces of paste forced through the orifices. The blade is set at an angle so that its trailing edge is close to the plate; this edge, and the leading edge, are staggered by a distance equal to the dia. of one orifice. This allows a regular flow of paste through the holes and the prodn. of well-shaped vols. of paste, in co-operation with the knife below the holes. Device gives a high output of prods., such as pommes dauphine and quenelles, which have to be shaped before frying. It is partic. useful where a large number of meals has to be prepd.

Patent FR-2242994-A1 (FR)
Title: Blood treatment and pressure measuring equipment - with proportional anti-coagulant metering
IPC: F04B43/06
Filed: 1974-09-03
Abstract: An automatic monitoring unit particularly for the treatment of blood from a number of patients simultaneously, has blood extraction devices, a variable-delivery pump, a blood treatment chamber, a bubble trap separating out any gas present, and means for returning the blood, together with the necessary interconnections. Those between extraction device and pump incorporate valves, and measuring devices for the blood pressure producing signals corresponding to it. The flow of blood is periodically interrupted, to allow measurement of blood pressure in the connection concerned at a time when this is equal to that at the point from which the blood is extracted. The signals control the pump so as to keep the pressure in the connections within preset limits representing the rate at which blood is taken from the patient, and also the valves, keeping them open as long as pressure is within the limits concerned when blood is flowing, while it is kept above a second value when flow ceases. Another detector shuts the valves when the cardiovascular condition of the patient passes set limits. The control unit also meters an anti-coagulant into the blood so as to keep the proportion constant independent of the flow rate.
