Title: Fluid density monitor for aircraft fuelling - uses float and magnet arrangement moving between limits in container
Inventor: POPKEN HERMANN
IPC: G01N9/18
Filed: 1975-10-31
Abstract: A device for monitoring the density of a fluid flowing through a pipe, in partic, for use with fuels, using a float moving between limits, is designed to be simple and robust and to operate reliably and without maintenance for long periods. The device may be used in aircraft fuel systems for safety purposes to distinguish different propellant types by their density differences in order to avoid incorrect fuelling. It clearly indicates density differences of the order of one hundredth and responds to those of one thousandth. A two piece magnet (34) is attached to the float (20) and a similar magnet (36) moves in a container (35) which limits its range of movement and thus that of the float. The position of the second magnet controls the fuelling valve.

Title: Torque limited container screw cap - has compression spring between cap and plug with ridged floor and slanting pawl surfaces
Inventor: GERDES THEODOR DIPL ING
IPC: F16J13/12
Filed: 1975-12-05
Abstract: The screw-on cap for a container or pipe end has a limited tightening torque, due to a friction release coupling and compression spring. The hollow outer cap (1b) has an inturned rim (1a) enclosing the inner plug section (2). A ring seal (10) is squashed between the mating surfaces at the container rim. The coupling bridge insert (6) has a spring (5) between its two legs (4), compressed between the projecting bridge boss (4b) and the inner rotary cap (1). A dished disc (7) covers the spring head to facilitate sliding. Under excessive torque, the inclined pawl surfaces (6b) of the bridge slide over the four circumferential ridges in the plug floor (3), against the spring force, preventing further tightening.

Title: IC engine fuel consumption reduction unit - pulls accelerator pedal as far back as possible after completion of acceleration
Inventor: VIRGILIO GUSTAV
IPC: F02D11/10
Filed: 1976-02-24
Abstract: Fuel consumption reduction unit has a throttle valve (2) positioned in the inlet manifold pipe (1) to the engine and can be swivelled along with the accelerator pedal (3) whereby in one end position the pipe is closed and in the other it is fully open. A differentiator (4) is coupled to the throttle valve and a control (6) in the form of for example a magnet or motor. The differentiator generates a signal when the acceleration phase is ended and signified by a closing movement of the throttle valve. This signal releases a retardation control unit (5) which after a delay time operates the control unit (6) to effect an additional variation of the throttle valve position in a direction which limits the suction cross-section and hence reduces the fuel consumption.

Title: Sizing and/or dyeing agent control - has a control valve to regulate squeeze roller pressure to give a constant content in fibre strands
Inventor: RUESCHER MARKUS
IPC: D06B3/34
Filed: 1976-03-30
Abstract: The system to control and regulate the content of sizing agent and/or dyestuff in fibre strands, by controlling the pressure of squeeze rollers and the speed of fibre travel through the rollers, uses a control valve to monitor the fibre travel speed as a proportional control value. The roller squeeze pressure is set according to the control value by a functional transfer. The system holds a constant value and volume of agent in the fibre material whether it is passing through the rollers at high speeds or at slow rates.

Title: Holographic nondestructive test for rotation symmetric body - enables prodn. testing for material faults in complete wheel batches
Inventor: ROTTENKOLBER HANS DR ING
IPC: G01B9/021
Filed: 1976-04-07
Abstract: A holographic arrangement for non-destructive testing of rotation symmetric bodies, in partic. testing vehicle wheels for material faults, is designed for series testing of complete production batches rather than random sample testing. It thus enables higher reliability standards to be achieved. Light from a coherent source (14) is deflected along the common axis of the rotation symmetric body (21) and a circular mirror (18). The test body (4) is mounted concentrically on the rotation symmetric body (21) which has a mirrored exterior (22) deflecting light to the test body inner surface (33). The reflected object beam (34) is compared with a reference beam (35) at the observation point (26).

Title: Particle accelerator having variable beam localising tube - between diaphragm and half-shadow trimmers built from interchangeable plates
Inventor: BENEDETTI RICCARDO DR RER NAT
IPC: A61N5/10
Filed: 1976-05-20
Abstract: A beam localising system is intended for use with a particle accelerator in radiation therapy and comprises half-shadow trimmers in conjunction with stop plates located near the radiation source. Between the stop plates and the half-shadow trimmers, a tube is mounted for localising the beam; this tube is built up from individual, removable plates. The tube cross-section can be adjusted by changing the plates to give any size up to the max. aperture between the stop plates and the half-shadow trimmers. Pref. an intermediate frame is incorporated between the stop plates and the half-shadow trimmers, near to the former; the aperture size of this frame is adjustable and the plates forming the tube are mounted on it. Used for radiation equipment used in radiation therapy. The use of replaceable plates enables a tube to be built up to suit the required size of irradiated area, and obviates the need for large numbers of tubes of different sizes to be kept in stock.
