Title: Electro-slag melting plant - with horizontally-adjustable base-plate for lateral adjustment of ring-shaped moulds
Inventor: RABINOWITSCH WOLF J
IPC: B22D23/10
Filed: 1974-01-21
Abstract: In plant with a chilled mould on a base-plate and devices to hold the consumable electrode in posn. w.r.t. the mould walls, the novelty is that the base-plate can be moved in any desired horizontal direction with the object of centering the mould w.r.t. the electrode, whereas the devices for holding the consumable electrode in posn. are fixed to the mould-walls. The horizontal adjustment of the base-plate is pref. made by mounting it on (a) balls which are free to roll on the foundation; (b) a water-bed; or (c) a gas-cushion. The result is a simple device for adjusting the mould posn. in the mfr. of hollow components where a mandrel is required in the mould.

Inventor: DAKIN JOHN PHILIP
IPC: C03C21/00
Filed: 1974-03-30
Abstract: Impurities, responsible for absorption losses from glass, are removed by immersing the glass in an electrolyte soln.

Title: Flowmeter with electrical output - has variable inductance transducer with analogue or digital display
Inventor: GEMPERLEIN HANS DIPL ING DR
IPC: G01F1/24
Filed: 1974-08-08
Abstract: The flow measuring instrument consists of a non-magnetic hollow tube with an internal taper containing a float with a ferromagnetic stem. The float stem runs in a guide and its lower end slides inside the coil former of an induction coil carrying an alternating current. The resulting variation of the coil inductance with movement of the float is amplified by an amplifier whose characteristic is adjusted to provide at its output a linear signal proportional to the flow rate in the tube. Either digital or analogue instruments may be used for indication. The instrument is responsive to low levels of flow and is of small dimensions so that it can be fitted where space is at a premium, e.g. in a vehicle.

Title: Pneumatic measuring balance - has power scale with jet-baffle plate system for direct force compensation
Inventor: ONNEN ONNO DIPL ING
IPC: G01D5/42
Filed: 1974-09-26
Abstract: The surface surrounding the jet is smaller than the effective jet cross-sectional surface. When the jet is closed all the functional surfaces of jet, baffle plate and power scale beam lie in the same plane. Two jets (1, 2) are arranged to operate against the baffle plate (4) of the force scale (3). One jet acts as the control and operates via a throttle (6) connected to an air intake supply (Pz). This jet is connected also to the input of a pneumatic compressor (5). The other jet (2) serves as the compensating jet. It receives the output pressure (Pa) of the compressor (5) which serves as a measurement signal. The distance between jet and baffle plate is thereby held more or less constant.
