Title: Tool for drawing rigid tube through rubber lined opening - with means for lubricating the lining bore to ease penetration
Inventor: BOUTON FRANZ MATERN FLORENTIN
IPC: B21D39/20
Filed: 1980-12-26
Abstract: A mandrel for inserting a tube through a hole in a wall or plate lined with a rubber sleeve comprises a composite cantilevered tube inserted from the opposite side of the wall or plate and incorporating (a) a dilatant tip to grip the interior of the tube, and (b) passages for discharging a suitable lubricant, such as petrolatum, over the surface of the rubber sleeve to ease the passage of the incoming tube. Useful for constructing heat exchangers etc. with several tube ends connected through the jacket and plate. Pref. the dilatable tip uses an elastic sleeve which can be pressurised internally and has a rough surface. Concentric tubes within the mandrel carry lubricant and the inflation medium respectfully via suitable coupling of successive mandrel sections. A coaxial hydraulic or pneumatic jack shifts the mandrel relative to the perforated and sleeve plate.

Title: Emergency stand by supply controller for ultra-fast changeover - takes derivatives of primary supply signal and reference signal and continuously compares to give changeover in less than 200 microseconds
Inventor: NOE MICHEL
IPC: H02J9/06
Filed: 1981-03-27
Abstract: Solid state switches exchange an electric load from the normal electric supply (51) to an emergency standby supply (52) providing high speed changeover by generating a derivative of the primary supply signal. A derivative of the reference signal is also produced, and the signals are continuously compared to provide changeover in less than 200 microseconds if the primary signal falls below the reference. Interface circuits (1,3) isolate the supplies from the changeover control circuit. The primary supply (s1) interface (11) supplies a circuit producing a reference signal (sdt). The interface also supplies a second circuit (6) which gives a derivative signal (sdv) from the primary supply signal. These two signals are compared (8). The selection of the logic signal (17,18) to determine which solid state switch is closed onto the load is determined by a logic circuit (16) in response to input signals (15,42, 21,27).

Title: Optical separator for fibre=optic systems - includes bi-reflecting prism with two auxiliary prisms ensuring that transmitted ray is aligned with incident ray
Inventor: MOUCHART JACQUES
IPC: H04J14/02
Filed: 1981-11-12
Abstract: The device is used for separating or superimposing two beams of light, by means of a bireflecting prism (PB). Light enters via a first tansparent surface (TI) to form a complete internal ray (FGI) which is incident on a reflecting surface (R1) which produces a reflected internal ray (FR1) and a transmitted internal ray (FT1). A second surface (R2) reflects the internal ray to leave normally through a transparent surface. The first reflective surface (R1) has a coating making it partially reflecting, and an auxiliary prism (PA1) of the same material as the main prism ensures that the transmitted ray leaves parallel to the incident ray. The two reflecting surfaces may be identical in which case a second auxiliary prism (PA2) adjoins the second reflecting surface.

Title: Zero-insertion-force socket for standard-outline integrated circuits - has base with two arms which fold around component and force contact strips onto pin faces
Inventor: REICHARDT MANFRED
IPC: H05K7/10
Filed: 1982-03-30
Abstract: The zero-insertion-force socket is designed for electronic components, partic. integrated circuits, of standard outlines. The integrated circuit (10) is inserted into a base consisting of rows of holes of conventional separation pitch set in a block of insulating material (12) which has recesses to minimise volume.
