Title: Elbow for circular section fluid duct - is formed from semi-circular sections with lapped and seamed edges
IPC: F16L43/00
Filed: 1973-07-05
Abstract: An elbow junction is made up in two halves (3) and (4) split longitudinally and jointed by lapping and seaming the edges, (5a), (5b), (6a), (6b), inside on the straight ends of the elbow, outside on the elbow curve itself. The elbow is assembled into the pipework by sliding straight ends inside adjacent pipes up to the shoulders (9) pressed into the elbow. Junctions may be made from steel sheet and light alloys and surfaces may be protected against corrosion by pretreatment by galvanising or lacquering. Strong and smooth gas tight joints are formed and the construction method is suitable for complicated junctions.

Title: Motor vehicle accident alarm and cut-out switch - uses mercury vessel outflow to separate supply electrodes and connect external alarm contacts
IPC: H01H29/20
Filed: 1973-07-19
Abstract: The accident alarm and cut-out switch for motor vehicles, has a crucible (A) containing mercury which connects together two electrodes (D) in the motor vehicle electric supply circuit. In normal conditions the supply current flows through the mercury. When the vehicle experiences a rapid decelaration, as in a collision, or when it turns over onto its side, the mercury is caused to flow out of its container vessel and the supply is interrupted. After leaving the vessel the mercury bridges any pair of many pairs of contacts, distributed all over the inside surface of the hemispherical housing enclosing the vessel, to cause generation of an alarm signal. These contact pairs are also located around the base of the vessel.
Patent FR-2326876-A1 (FR)
Title: Dust emission from seed dryer reduced by air flow shutters - which are closed during periodic batch discharge of dried seed
IPC: F26B21/12
Filed: 1973-12-05
Abstract: Dust retention device is used for hot air seed dryer having movable baffles which can be adjusted to cut off the air flow through the dryer. Each baffle takes the form of a shutter pivoted about an axis at right angles to the direction of air flow. In the 'open' position, the shutters are parallel to the air flow. Pref. each shutter is profiled like an aeroplane wing with its leading edge directed into the air flow. Each shutter is pref. pivoted between two fixed baffles. The pivoted shutters are pref. all linked mechanically to be moved by a single pneumatic actuator. The linkage pref. actuates an electric timer which cuts off the drying air burner if the closed shutters are not reopened within a given interval. Used to reduce the amt. of dust released from a seed dryer to pollute the surrounding atmosphere and countryside. The device can be fitted quickly and inexpensively to existing dryers. The device reduces dust emission by 90% as dried batches are periodically discharged.

Title: Vidicon camera tube target - has a transparent resistive layer on the exposed surface to give picture sharpness
IPC: H01J29/45
Filed: 1974-02-05
Abstract: Camera target for a vidicon of n-type semiconductor is covered on the face exposed to incident radiation with a transparent resistive layer which is pierced from the opposite face with a mosaic of holes extending as far as the resistive layer, which receives through these holes, negative charges of an electron beam, sweeping the opposite face. There is no or little loss of sensitivity, esp. of short (uv) wavelengths, since the active part of the target is at the receiving surface rather than at the opposite face, so that recombination in the thickness of the wafer is avoided. Parasitic currents are also avoided or reduced.

Title: Hollow clay brick with key for mortar - has curved tongues formed at ends of channels by wedge shaped tool
IPC: B28B11/00
Filed: 1974-04-23
Abstract: Rows of ventilating channels (2) are separated by horizontal (1) and vertical partitions. All the horizontal partitions except the lower ones, of the central row are bent downwards, these tongues (1a) being longer at the top channel and decreasing towards the bottom channel. When two bricks are laid end to end, all these tongues form a good key for the mortar. In manufacture, these tongues are formed by inserting a wedge shaped tool into the soft clay before firing, immediately after the cutting wire has cut the brick. In an alternative design all the channels terminate in tongues and by using a short triangular too, all the tongues are made the same length.

Title: Semiconductor protective cct. against potential rise - has differential doping levels in defined regions forming lower blocking impedance
IPC: H01L27/06
Filed: 1975-02-07
Abstract: The protective circuit for integrated circuit configurations has a semiconductor body with two layers of p- and n-conductive material, forming a pn-junction. In the first layer is formed a region giving a second pn-junction with the layer. Further regions form two more pn-junctions. Appropriate connections for the second and third regions provide a series connection of the third and fourth junctions, forming diodes between circuit points to be protected against high voltage gradients. The doping levels of the first, second and third regions are higher than that of the two layers so that the first pn-junction diode has a higher leakage current and a lower blocking impedance than the third and fourth junction diodes, on voltage application whose polarity biases the first, second and third junction diodes in blocking direction and the second junction diode in forward direction.
