Title: Motor generator set which gives mechanical output - has annular solid rotor mounted between two fixed windings
IPC: H02K47/00
Filed: 1973-05-25
Abstract: A motor generator is made with three interacting parts. A fixed outer coil (17) is mounted on the inside of a case (10) and inside this is an annular solid ring (20) which may be coated on both sides with ferrite (29) and a fixed inner coil is mounted on a non-rotating axle (25).

Title: Shredded sugar beet press filling device - with gastight star wheel feeder above pressurized filler shaft
IPC: B30B9/12
Filed: 1974-05-02
Abstract: A device for filling shredded sugar beet slices into the housing of a slice press with a pressure screw spindle has a gastight star wheel feeder between the wet beet slice worm conveyor and the filler opening. A pressurised gas supply pipe enters the space above the level of the wet beet slices downstream of the star wheel feeder. This makes the filler opening independent of the geodetic height so that it can be designed very short. The degree to which the moisture is reduced by the press can be increased, also the throughput of the press.
Patent FR-2273201-A1 (FR)
Title: Intermittent differential shaft drive mechanism - converts input rotation steps to controllable amplitude output rotation steps
IPC: F16H3/72
Filed: 1974-05-27
Abstract: The transmission provides a variable amplitude discontinuous output shaft rotation from a fixed amplitude discontinuous input shaft rotation. The amplitude of the output rotation is controllable during operation. An input shaft rotating in fixed amplitude steps drives a differential cage via gears. One of the differential pinion shafts is an intermediate shaft used for control and the other is the output shaft, rotating in steps of different amplitude from the input. The control of amplitude is achieved by controlling stepping motors and an electromagnetic brake in response to the number of electrical pulses derived from sensor discs on the input shaft. The motors position satellite wheels in a track which only transmits drive after a certain rotation, due to the shape of the inner disc.

This drive is in turn driven by a double gear train inside the casing, driven in turn from a variable speed unit. Weights can be added to the top part of the central shaft (38) and a dynamometer device (44) positioned under the bottom part.
Patent FR-2282396-A1 (FR)
Title: Crane load monitoring system - uses linear interpolation to establish safe load for comparison with actual load
IPC: B66C23/90
Filed: 1974-08-09
Abstract: Two sets of predetermined values of first and second parameters of the geometrical state of the crane are arbitrarily chosen, so as to form pairs of one in each set, and a numerical reference value is allocated to each pair, representing the predetermined maximum load for each pair. At any moment during lifting a pair of consecutive values is selected, between which the instantaneous parameter occurs. First and second values are then calculated by linear interpolation between the values selected, also a third one representing the maximum permissible load. The third one is compared with a fourth one representing the actual load and a signal is emitted representing the value of the latter in relation to the maximum permissible figure.

Patent FR-2256123-A1 (FR)
IPC: C04B35/599
Filed: 1974-12-27
Abstract: Aluminium nitride or aluminium oxynitride and silica or silicon oxynitride are reacted with one another at a temperature between 1200 and 2000 DEG C to form a ceramic material of silicon-aluminium oxynitride. At the said temperature, not more than 60% by weight of aluminium nitride and first and second metal oxides, including boron oxide but excluding silica, are present in the mixture. In this case, the metal oxides are present in such a form that they do not introduce into the mixture any combination of only magnesium oxide and alumina, and that they bond during the reaction with a part of the silica to form a silicate glass which has a liquidus temperature which is lower than the liquidus temperature of a silicate glass formed from silica with one of the metal oxides alone. At least one of the metal oxides can be replaced by a silicate.

Title: Corrosion protection of plant in chemical and allied industries - where plant is alternately anodically polarised and short circuited
IPC: C23F13/00
Filed: 1976-08-12
Abstract: A polarising current is periodically applied via a cathode to keep the anodic potential of the object within prescribed limits; and, during the pauses between the supply of current, the anode is short circuited with the cathode. Used in corrosion protection of plant in the chemical-, food- and textile- industries, and in the mfr. of cellulose or paper, Where a passive layer is formed on the metal plant. The short circuit assists in maintaining the desired anodic potential so the control equipment is less frequently switched on and off and the corrosion protection is more reliable.

Title: Monitoring device for rotor heating - has bidirectional counter receiving slip synchronised voltage and pulses representing cooling conditions
IPC: H02H6/00
Filed: 1976-11-12
Abstract: The device monitors the heating of an electric machine rotor during braking and starting processes and also during excessively long periods of hard braking. It comprises a circuit (2) generating a voltage synchronous with the machine (1) slip. A generator (4) produces a pulse train whose frequency depends on the cooling conditions. A bidirectional counter (3) counts half-waves of the voltage synchronous with the slip, which are applied to its upward counting input. Half-waves of the pulse train are applied to its downward counting input. The synchronous voltage may be generated using a static rotary field relay with stator and rotor. The polyphase stator winding is fed from the electric machine terminals.
