Patent FR-2238572-A1 (FR)
Title: Composite mouldings with a two phase foam core - made using a grid to restrict aggregate fillers to a peripheral zone
IPC: B29C44/04
Filed: 1973-07-23
Abstract: Mouldings having an inner core of foamed resin surrounded by a mixed phase of foamed resin and low density aggregate fillers, moulded with the aid of rigid porous insert used to confine the aggregate particles to the peripheral regions of the cavity until the resin foams and hardens.

Title: Resilient supporting unit for bridge structure - has embedded metal ring plate with grooves and projections
IPC: E01D19/04
Filed: 1974-04-22
Abstract: A metallic ring-like member is affixed and buried in an intermediate portion of a resilient structural support made of an elastic material such as rubber, so that bulging of the intermediate portion in the peripheral surface of the resilient supporter is prevented by the ring-like member. Elastic layers disposed above and below the ring-like member are interconnected across a large hole in the ring-like member. The elastic supporter is made in the form of a strong block which has a number of elastic layers. Moreover, the elastic supporting unit can be formed in a circular shape, and thus directivity of the elastic supporting means is eliminated when used for erection.

Title: Electron beam target scanning control - converts intensity of beam on target to current signal displayed on oscilloscope for beam direction control
Inventor: BRUEL MICHEL
IPC: H01J37/302
Filed: 1975-01-08
Abstract: The scanned target is surrounded by an auxiliary electrode that collects electrons that pass the target. The position of impact is shown on an oscilloscope with X and Y coordinates. The oscilloscope includes a Wehnelt electrode modulating the intensity of the electron beam, and supplied by a voltage which is a function of the current on the target due to the electron flux. A summator adds the currents (Ia) and (Ib) produced by the beam impinging on the target and surrounding electrode respectively. The target current (Ia) is compared with a reference current, and an analog gate is connected to the outputs of the comparator and summator to give an output signal I't = (Ia + Ib)Y(Ia-epsilon), that is transmitted to the Wehnelt electrode via an amplifier, differentiating between direct input I't and inverse input It=Ia + Ib obtained from an integrator. The anode of the oscilloscope is connected to an amplifier and voltage divider in series, which release a voltage proportional to the acceleration voltage of the electrons. Amplifiers are to take the current signals of the oscilloscope and control the electron beam deflecting plates. Used for the sepn. of isotopes, ionic implantation, irradiation, ionic machine finishing, etc.

Title: Implosion generator producing acoustic impulse - using main and branch liq. jets driven by magnetic field at high speed producing hollow space
IPC: F15B21/12
Filed: 1975-04-18

The liquid jet is driven by a magnetic field which is practically stopped for a brief moment. The speed selected is sufficiently high to produce a hollow space with subsequently an implosion being produced. The main liquid jet is subdivided into at least two branch liquid jets with the branch jets being diverted into a plane about vertical to the trajectory of the main jet. The branch liquid jets are offset in relation to each other by about 90 degrees.

Title: Combined space heating and hot water system - has load by-pass from radiators to reservoir with time switch and thermostatic controls
IPC: F24H9/20
Filed: 1975-05-05
Abstract: The space heating and hot water system consists of a water boiler (1) with cold water feed with an inlet bath control (4) through an inlet control valve. The hot water outlet through teh top of the boiler passes through a two-way control valve (12) the main circuit passing to a number of hot water radiators (6). The secondary circuit feeds a hot water cylinder (8), which returns cold water from the reservoir through an outlet valve (16). The control valve cycle is controlled by a timing clock switch (17), with an additional control in the form of a thermostat (19) part way up the reservoir so that the hot water circulation is switched to it when cold water reaches the height of the thermostat. The heating capacity for the reservoir is adequate even when the time clock is at the shortest time period.
