Title: Automatic fire retarding door for ventilation duct - two flaps block hot fumes flowing in either direction
IPC: F16K17/38
Filed: 1974-06-06
Abstract: A ventilation duct has a sheet metal box (1) with an inlet (5) one side for normal ventilation, opposite an outlet (3). The fire retardant door (6), of asbestos in the form of a flap, is hinged (8) at the top (2) of the outlet side. Below this is a second flap (10), of sheet metal, hinged (11) at the top (4) of the inlet side. Both flaps are held open by a catch (15), comprising two parts (16, 17) joined by fusible solder. Heat breaks this catch, allowing both flaps to drop. Gas flow in the normal direction holds the asbestos flap on its seat, an opposite flow is arrested by the metal flap.

Title: Small motor stator unit with two part core - comprises cast winding section and ribbon wound core back
IPC: H02K15/12
Filed: 1974-09-10
Abstract: The aim is to facilitate the manufacture of small stator units, for example for driving spindles of spinning machines. The machine windings, suitably insulated, are cast into a magnetic mix to form a cylindrical unit representing the part of the core corresponding to the teeth in a conventional construction. Onto this is wound a continuous ribbon of steel to give a laminated core back. The end windings stand clear of the cast core section to allow subsequent interconnection of the coils. Similar construction method may be employed in building a rotor. In such a case the moulded core can, advantageously, be a wooden cylinder.

Title: Air purging valve for water pipeline - has float operated needle valve orifice in outlet closure plate movable vertically
Inventor: ALEXANDRE PHILIPPE
IPC: F16K24/04
Filed: 1974-09-30
Abstract: The cylindrical float chamber (4) is bolted to the pipeline (1) and its upper end has a cover plate (8) with a large central orifice (9). The float (5) slides in guides (6) and is provided with a pointed valve head (7). The valve plate (10) slides on guide rods (13) and (14) attached to the cover plate (8). When the pipeline is being filled with water, air flows out through the orifice (9) until the water level rises sufficiently to push the float (5) upwards and the plate (10) closes the orifice (9). Air bubbles which afterwards collect in the float chamber depress the water level and cause the float to sink and open the sonic orifice (11), allowing the air to escape.

Title: Tank filling control valve - has float unlocking and coupled to second float for controlled valve flap closure
IPC: F16K31/28
Filed: 1975-02-04
Abstract: A tank filling control valve is fitted inside the tank and is connected to the pipeline through which the tank is filled. The float (F1) is attached by a lever (65) to a spindle (59) which is normally prevented from rotating by the pawl (68) engaging a notch in the boss (65a). When the liquid in the tank rises to a predetermined level a second float rises and rotates the lever (55) which acts through the rod (58), lever (66), and cam (67) to lift the pawl (68), allowing the float (F1) to rise and apply an additional force to the second float through the slot (5) and bolt (4) so that the shaft (56) rotates with a rapid action to close the valve flap contained within the valve body. The flap has an opening allowing drainage of the pipeline until further float action closes this opening.

Patent FR-2266256-A1 (FR)
IPC: G11B20/12
Filed: 1975-03-24
Abstract: 1495459 Automatic control SIEMENS AG 12 March 1975 [29 March 1974] 10205/75 Heading G3N The speed of a magnetic tape is controlled by a time varying reference having a portion that is triggered by a tape start signal rizes linearly to a nominal tape speed, and a part that is triggered by a tape stop signal and falls at a greater rate. In the embodiment, tape drive motor MO is controlled according to the difference between an actual motor signal # from tachometer TA and the speed reference from device ST via potentiometer p which sets the nominal tape speed. The device ST, described with reference to Fig. 4 (not shown), is triggered by a binary start/stop signal S, to charge a capacitor at a given rate e.g. corresponding to the maximum permissible tape acceleration to give the rising speed reference, the capacitor being discharged at a faster rate by a switching transistor to provide the falling characteristic. The motor MO, and thus the tape, may be reversible. The above system minimises gaps between adjacent blocks of stored data on the tape.
