Patent FR-2315697-A1 (FR)
Title: AC supply failure to three phase motor - is sensed by unbalance of magnetic field surrounding magnetisable switch
Inventor: DOMANSKI THADEE
IPC: G01R19/165
Filed: 1975-06-23
Abstract: Magnetisable flexible blade switches enclosed in glass phials surrounded by a winding and normally used in d.c. circuits. By arranging that half wave rectified currents and phase shifted half wave rectified currents flow in the coils to generate magnetic fields in the same sense, they can be used for protection of three phase motors. A magnetisable flexible blade switch (2) is enclosed in a glass phial (1) on which coils are wound for each mains supply phase. Each coil comprises two half windings (3, 4) and each half winding is connected through a diode (5) to the same supply phase. The windings are positioned to generate magnetic fields in the same sense, thus a fault in one phase causes the switch to operate.

Title: Film developing bath using minimum liquid quantity - has spiral bobbin on which film is wound with close fit inside bath
IPC: G03D13/14
Filed: 1975-09-26
Abstract: The capacity of the bath (1) is reduced to a minimum, and this capacity being adapted for several film lengths. Each part of the interior of the bath, the parts of the bobbin and band (15) are formed and assembled in such a manner that the empty spaces, which will be filled by liquid, are reduced to a minimum. To form a minimum space between the lower side of the bobbin (8) and the bottom of the bath, the lower side of the bobbin is flat and rests directly on the flat bottom of the bath. Passage of liquid is ensured by radial and non radial cutouts (17) in the bottom of the bath.

Title: Pushbutton control unit for moving machinery - has two pushbuttons for forward and reverse and slider potentiometer for speed variation
IPC: H01C10/50
Filed: 1975-12-18
Abstract: The pushbutton control units, for moving machinery, consists of two spring-loaded pushbuttons (15) each acting on a microswitch (26) mounted on the outside of the unit's main block (10). When one pushbutton is depressed it releases its microswitch and a sloping face (15A) on one side of it pushes a slider (13) along a keyway (10a) inside the block against the action of a spring (20). The slider has a shoulder (13B) that acts on the plunger (25B) of a linear potentiometer (25). As the button is depressed further so the potentiometer's resistance changes and the machine moves faster (or slower). The microswitches switch the machine on and off and each is for one direction of machine movement.

Title: Convertible resilient furnishing unit - includes inflatable sphere with internal support elements forming chair shape when sphere is deformed by external force
IPC: A47B85/00
Filed: 1976-01-07

Title: Gyroscope inertial force meter - has vertically pivoted gimballed gyro, connected by wire to dynamometer
IPC: G01C19/02
Filed: 1976-01-19
Abstract: The gyroscopic force meter operates in the rotation plane of a spinning top which tends to reduce the magnitude of its orientation change. A gyroscope is gimbal-mounted on a vertical support and connected by a wire to a dynamometer whose hook is in the precession axis and which maintains it in the inclined position while still allowing circular displacement in the horizontal plane. The vertical axis of the gimball carries a lever arm to which a tension wire and a return spring are attached s.t. a precession movement simulated in two directions maybe conveyed to the gyroscope. The force of the return spring is measured at its elongation point when the rotation axis of the top is in the elastic range of the spring of the dynamometer.

Title: Cutting press for electrical machine lamellae - has program operated multiple tools on ram for different shapes
Inventor: SCHNEIDER FRANZ
IPC: B21D28/22
Filed: 1977-06-03
Abstract: The cutting press is used for making slots into circular segment shaped lamallae of electrical machines. The thin plates are fed after each ram stroke by a coordinate guide of the clamping table correctly to the cutting tools. A step by step indexing movement is superposed. It is possible to cut, without changing tools, outside shapes and slots into plates which differ from the actual stator or rotor slots. The precut segments can be made with relatively rough outline and hence they are suitable for different machine types. No subsequent correction work is needed for these slotted lamalae. End plates with larger grooves can be cut without changing tools. The cutting tools (3,4) are provided with arbitrary cutting profiles (13,14,15,16) held outside the effective range of the slot profile (12). These cutting profiles are brought by a program into effective contact with the lamella (7) to be machined.
