Title: Movement of cylinders through a drying stove - by applied sinusoidal movement of successive supporting rollers
IPC: F27B9/24
Filed: 1974-05-17
Abstract: Cylindrical objects, e.g. pipes, are heated in a gas fired stove while using externally-driven shafts to generate a sinusoidal movement in a vertical plane of a series of supporting idler rolls - thereby inducing rotation and passage of the cylindrical object through the stove. For heat treatment of cylindrical and tubular materials, e.g. for the curing of resin in asbestos fibre pipes. The stove operates as a continuous process and occupies several levels, therefore requiring less ground space than a conventional tunnel type dryer.

Patent FR-2274638-A1 (FR)
Title: Mixing and degassing compsns with viscous rosins - by internally recycling a cascading film under vacuum
IPC: B29B7/82
Filed: 1975-04-09
Abstract: In homogenising and degassing a mixt. of matl. added successively into a vessel operating under vacuum, the constituents are first mixed by rotary paddles which sweep the convergent wall of the base of the vessel, and then are lifted by a screw suspended axially in a tube mounted vertically in the middle of the chamber. Matl. lifted to the top of the tube can drain down a sloping radial skirt on top of the tube and spill back towards the base of the vessel. The temps. of the contact surfaces of the tube and its skirt are controlled by banks of heating or cooling units attached to their rear faces. The appts. is esp. used for degassing mixts. of thermosetting resin systems and fillers etc., e.g. for mfr. or components requiring good electrical insulation characteristics. Degassing may be effected relatively efficiently from the film of matl. flowing over the skirt on top of the tube. Volatile matl. can be extracted before the resin viscosity rises sufficiently to excessively inhibit matl. flow and migration of volatile matl.

The first fold is pref., made by lowering the pancake from a continuously advancing belt on to a belt travelling initially in the opposite direction but which reverses after half the pancake is transferred to it. The second fold is pref. made by hanging the once-folded pancake over a conveyor rope.

Title: Stratified charge four stroke IC engine - has spark plug in ignition chamber connected to precombustion chamber
IPC: F02B75/02
Filed: 1975-08-18
Abstract: The engine has an auxiliary inlet valve (3) which admits a rich mixture into the precombustion chamber (5). This is connected by one passage (12) to an auxiliary ignition chamber (6) which is fitted with a conventional spark plug (8). A lean mixture is admitted through the main inlet passage (9) by the main inlet valve (2). This ignites in the main combustion chamber (4) after admission of the burning gases through the passage (11) from the precombustion chamber (5). The precombustion, pre ignition and main combustion chambers are all cast in the main cylinder head. This method of ignition gives a steadier flame speed than the normal method of ignition.

Inventor: MAUPAS PHILIPPE
IPC: C07K14/02
Filed: 1975-12-19
Abstract: Isolation of hepatitis B virus sheath antigen (HBs) is carried out by first contacting HBs-contg. serum with an imm miscible liq. fluorinated aliphatic hydrocarbon, separating the phases, and recovering the serum phase. The serum phases is then contacted with a solid molecular adsorbent, which is then sepd. from the liq. phase and treated to desorb the antigen. The prod. is pref. subjected to further purification or concn. by selective adsorption. The antigen can be used to prepare vaccines against hepatitis B (serum hepatitis). The process gives high-purity HBs antigen without modifying its physicochemical or immunological properties.

Title: Control and protection circuit for transistor switch - uses voltage across load to keep switch ON after end of triggering pulse
IPC: B60Q11/00
Filed: 1976-01-28
Abstract: The control and protection circuit, for a transistor switch, applies a current pulse to the base of the transistor switch (1) so that it turns on and a voltage is developed across the load (2). The voltage is fed back to the transistor (3) controlling the transistor switch so that as long as this voltage is above a given limit the transistor switch is held on even after the current pulse has finished. If the load is short circuited the voltage across the load drops and the transistor switch is automatically biased off. The pulses are produced by an RC circuit (7) and applied via a third transistor (6) to the base of the control transistor. A current limiter (12) is provided to protect the transistor switch during the presence of a pulse. The limiter blocks the third transistor (6) if the current flows through the series resistor (13) is too large.

Title: Sizing system ror shoes - builds up reference numbers from min. and max. heel circumferences of population group
IPC: A43D1/02
Filed: 1976-05-06
Abstract: The design concerns a method of measuring the human foot for selecting the right size of footwear. A representative size for the foot is the so called short heel circumference (X) which is taken along the imaginary line dividing the foot from the leg. This measurement can be supported by a further unit such as foot width. The system of sizes expressed in reference numbers is based on measurements carried out on a group of population. The range is subdivided into several groups, each with a reference number. The show shell is selected to have an inner measurement equivalent to the measurement taken over the short heel circumference, which is actually the max. value of the measurement for a population group. Each shoe within the size grading has a reference data which corresponds to the measurement of the group.
