Title: Fixing pin into thermoplast - by ultrasonic energy welding pin end into hole in thermoplast
IPC: B29C65/64
Filed: 1972-03-24
Abstract: A method for connecting a component, e.g. a rod or bar, to another thermoplastic component consists of inserting one end of the rod into a hole in the thermoplastic component. The rod has a flange set back at a little distance from the end to be joined to the thermoplastic component, while this joining end has keying surfaces or similar. Ultrasonic energy is applied by a sonotrode to the flange surface remote from the thermoplastic component so that, as the rod is pushed into the hole, thermoplastic flows into the keying surface. In the final position, the flange face nearest to the thermoplastic material engages it, pref. lying flat on its surface, so that the rod projects from the thermoplastic surface. Typical material are acrylic polymer and steel for the rod.

Title: Monochromator with automatically adjustable slits - lip of slit adjusts potentiometer to control lip micrometer
IPC: G01J3/04
Filed: 1973-08-24
Abstract: The sweep system of a monochromator operates a rotating screw thread (1) whose movement is transferred (2) to the slider (3) of a potentiometer (4). A voltage is obtained proportional to mechanical movement and to the frequency or number of waves. A motor (6) drives bevelled gears (7, 8) which act on a micrometer screw(9, 10) to move one lip (12) of the optical slit (13), the other lip (11) remaining fixed. This moves the slider (14) of a potentiometer (15) and causes a voltage proportional to the slit width to be compared (5) with the voltage proportional to the sweep, any difference causing the motor (6) to operate.

Title: Bottom blowing converter blast system - using octagonal lime-oxygen loop for tuyeres shrouded by enveloping gas tubes
IPC: C21C5/48
Filed: 1973-09-14
Abstract: A system to feed oxygen, lime and an enveloping gas into a quality-basic oxygen process converter consists of a closed-loop distributing main below the converter bottom, with branch pipes to take the lime entrained by the oxygen to the tuyeres. At two points, a fresh oxygen/lime mixture can be added to the loop. Flexible hoses carry the enveloping gas from a central point to each tuyere where it shrouds the oxygen/lime tube in the annulus left be a concentric outer tube. This eliminates the conventional cylindrical collector and facilitates the individual exchange of tuyeres. Damage on one does not involve other tuyeres; the system is simpler and requires less upkeep.

Title: Detection of hydrogen or uranium fluorides - using double mirror, one cooled, and estimating condensation from light intensity
IPC: G01N25/14
Filed: 1974-08-02
Abstract: HF or VF6 can be detected in exhaust gases from ureanium separation plants by passing a sample over a surface cooled below the saturation temp. for the component i.e. below the dew point. The surface is a twin mirror one cooled by liquid N2 and the other uncooled. Both are illuminated by a common light source, and both have identical photo-electric detectors. The quantity of condensate is thus calculated by comparing the signal from the two detectors on a meter. The mirrors and windows are made from polytrifluorochloroethylene. This gives a continuous direct method of determination to prevent hazardous atmospheric pollution.

Title: Electron microscope for high resistance samples - has secondary sweep discharging main sweep lines between main sweeps
Inventor: VICARIO EDMOND
IPC: H01J37/28
Filed: 1974-09-16
Abstract: The electron microscope has an auxiliary sweep to release the local electrostatic charges which the main sweep beam has produced on the surface of a sample. The altenating sweeps are obtained by successive line sweeps such that a line is swept by the spot of the principal beam. The principal beam is switched off and the auxiliary beam spot discharges the line during the time normally used to sweep the following line. The microscope also has a chopper circuit at the output of a detector. The chopper switches off the secondary electron detector during the activation of the auxiliary beam so as to eliminate any noise due to free ions in the vacuum chamber of the instrument. The microscope may be used for insulating material samples which have a high electrical resistivity.

The unit is accommodated in a bore in the spherical head, between the bottom of the bore and the front face of the cylindrical boss sliding in it.
Patent FR-2259901-A1 (FR)
Title: Injection of sulphur dioxide into musts - using continuous flow through jet of metered liquid proportioned to must flow
IPC: A23L2/44
Filed: 1975-01-31
Abstract: Sulphur dioxide is injected into fermentation grape musts, wine or other fruit or vegetable extracts, by direct metering of liquid SO2 and injection into the produce stream. Liquid SO2 is stored in a cylinder and flows through metering a pump and to a jet. The SO2 flashes after passing through the jet and mixes in the liquid flow. This flow is measured in a meter and the setting of the pump is controlled by a proportionator so that a constant ratio of SO2 to liquid is maintained. The pump can be of piston or membrane type. The jet is kept shut by a spring loaded device but which the pressure from the pump pushes open, esp. during the pumping stroke of the pump. The meter can be a rotary piston with counter or an inductive type quantity meter. Used for treating fruit and vegetable extracts, esp. grape musts for wine prodn. with SO2. In conventional processes the pressure of the SO2 is set on a monometer and the flow manually controlled through a valve. The stored SO2 is first evaporated in an expansion chamber and the flow controlled as a gas. The pump has to be determined and the valve setting estimated from the liquid flow. In the present process, the SO2 is metered accurately as a liquid and its flow ratioed to the liquid flow. This gives precise and accurate dosing and avoids the tendency for over and under dosing inherent in the scheme outlined above.

Patent FR-2265229-A1 (FR)
Title: TDM data transmission for system bits - uses data frames, each containing given information bits and specified system bits
IPC: H04J3/14
Filed: 1975-02-25
Abstract: A first number of system bits together with given information bits form a coherent block. The second number of different system bits consists of blank bits without any information meaning. At most the first sytem bits are used for frame synchronisation, and these system bits ensure the block position recognition and/or synchronisation of an error correction device. The first system redundant bits used for frame synchronisation form a coherent synchronisation word preceding the given information bits, and the synchronisation word position recognition is used for speed balancing in the total flow, when strict synchronisation between the sender and transmission fails. Then the number of blank bits is changed.

Title: End shaping of helical compression springs - using progressive pitch reduction over diametrally opposed end regions to reduce noise
IPC: F16F1/12
Filed: 1975-10-22
Abstract: The pitch of the spring over a certain length near the ends is modified to produce even load transfer from the end caps and reduce noise at high loads. The spring (R) is held between two end caps (1,2) which have upturned edges (8,9) to resist lateral displacement of the spring ends. The central windings have a constant pitch angle, but this angle decreases to zero over a length (4,5) of 1/4 turn at the ends. For best results, these portions should be diametrally opposed. Variants are possible in which the end caps are not flat, but shaped to have a pitch equal to the wire dia. or less than the spring pitch.
