Title: Radiator cooling fan for IC engine - has fan blade forming rotor of fan driving electric motor and speed detector to control current supply to stator coils
Inventor: BARGE JEAN
IPC: F01P5/04
Filed: 1981-03-13
Abstract: The cooling fan includes a set of helical blades (2) between a hub and outer rim. The blade assembly also forms the rotor of the motor driving the cooling fan. Magnetic pole pieces (12) are attached to the outer surface of the blade rim, whilst stator coils (14) are positioned around the frame of the fan structure to interact with the rotor poles. A sensor (17) detects the speed of rotation of the fan, in order to provide a signal to a frequency divider which in turn operates switching transistors controlling application of current to the stator coils. The hub of the fan blade is held on four support arms extending in from the outer edges of the supporting frame.

Title: Sintered metal parts prodn. - by pressing mixt. of metal powder and binder in die contg. holes, so binder is forced through holes to leave metal compact which is sintered
Inventor: GLADDEN THOMAS
IPC: G04B37/22
Filed: 1981-04-23
Abstract: A metal powder is mixed with a plastic binder to make a paste which is fed into a mould. The mould contains holes where at least one dimension of the cross-section of the holes is similar to the grain size of the metal powder. Heat and pressure are applied to the mould or die, so the major part of the binder is driven out through the holes while forming a pressed metal compact. The compact is then sintered in a reducing atmos. at above 900 deg.C. The paste is pref. injected into the mould. The metal powder is pref. stainless steel; Ni-steel; Fe; Cu; Ti; Zr; Hf; Ta; W; Rh or Re. The binder is pref. an organic cpd., esp. wax; paraffin wax; polythene; or polymethyl-methacrylate; and may include a solvent. Most of the binder is removed in the pressing operation, so strong green blanks are obtd. and the binder removed from the die can be re-used.

Title: Small battery operated alarm clock - has dial light operated by push button with protective locking lever to prevent wastage of battery power
Inventor: SCHULTHEISS UDO
IPC: G04B19/30
Filed: 1981-06-15
Abstract: The small battery operated alarm clock (1) has a light (12) in one corner of the face to illuminate the position of the hands. A pushbutton (11) to one side of the face is arranged to operate contacts (14) inside the casing to turn on the light. A sliding control switch (3) is mounted below the pushbutton, so that it may move vertically. In its lower position the word 'ON' is displayed, and the pushbutton may be operated. If the sliding control is moved upwards, an insulating tag (13') is inserted between the pushbutton contacts. This prevents the light being turned on - partic. when the alarm is in luggage, so that the battery power is not wasted. This same sliding switch may also put the alarm in the operational state, or shut it off for travelling.

Title: Measuring system for optimising electrical earth connection - balances phases of incident and reflected waves from frequency generator to transmission line connected at earthing point
Inventor: SIREL MICHEL
IPC: G01R27/16
Filed: 1981-10-20
Abstract: The connection is effected by driving a spike into the ground. The spike is connected to the central conductor of a coaxial cable whose outer conductor is not connected. The conductor is connected to a directional coupler and connecting block to an impedance analyser. This generates frequencies over a wide HF range and provides analysis at those frequencies. Alternatively, the conductor can be connected through a second directional coupler to an analyser covering the HF and UHF frequency ranges. The analysers and a tracing table are connected to a processor powered from a battery driven AC power circuit. The processor provides automatic adjustment to balance the phases between cables transmitting the incident and reflected waves to and from the earth spike. The processor determines the graphical points for display on a Smith chart on the tracing table. Earth connections for protection against lightning and em interference may be optimised by this method.

Patent FR-2520489-A1 (FR)
Inventor: ESCANDE HENRI
IPC: F26B17/08
Filed: 1982-01-28
Abstract: Continuous drying chamber for fruit, vegetables etc.. The dryer is of the type which contains a series of horizontal conveyor bands at several levels. The bands carry the prod. through the chamber while hot air is blown longitudinally along the conveyor bands by a battery of fans installed at several levels, one above another. Pivoted baffles are installed to allow a controller circulation of drying air to different levels of conveyor bands. Pref. an extra fan is installed to blow cold air, as required, transversely across some of the conveyor bands. The drying chamber is for treating vegetables and fruits, esp. plums for the prodn. of prunes. The adjustable baffles can be used to direct the greater part of the total drying air flow to a partic. zone of the chamber. This facility offers a wide range of processing possibilities. Drying can be speeded up, e.g. in two hours plums can have about 30% of their moisture removed.

Filed: 1982-10-05
Abstract: Filter easy to manufacture and of high directivity. It consists of a photographic plate provided with means for transmitting light radiation permitting the incident radiation to be limited depending on its direction, these means being represented by the photosensitive layer 3 consisting of portions which are transparent to the incident radiation and are separated by opaque walls 3a, 3b, etc., which layer is obtained by a photographic recording using illumination 5 through a mask 4 in order to create on the surface transparent zones separated by opaque zones, these zones extending into the thickness of the layer in order to form, respectively, the transparent portions and the opaque walls. The invention is particularly applicable for the production of directional cathode ray tubes.
