Title: Magnetic proximity detector for metal parts - has oscillator with control input and resonant circuit emitting signal
Inventor: ROTHENBURGER PIERRE
IPC: G01V3/10
Filed: 1974-10-10
Abstract: A rectifier and screen holder (REF) receives the vibrating signal (VO) and supplies a d.c. signal (Vf). A switching and amplifier stage (DET) receives the d.c. signal at one input and a reference signal at another input and produces an output signal (Vd) with two levels. A feedback (RR) receives the output signal and applies a feedback signal (Vr) to the control output of the oscillator (OSC). These circuit parts are so arranged that, in the absence of a metal part at the resonant circuit (CO), the output signal assumes the first level and, in the presence of a metal part, assumes the second level.

Title: Seal for bottom of door - has magnetic bar drawn from U-section against force of springs engaging guide dowels
IPC: E06B7/20
Filed: 1974-11-26
Abstract: The seal for the underside of a door (3) has a magnetic and rubber bar (5) within an inverted U-section fixed to the door base. The bar is drawn down by a magnetic strip fixed to the door frame sill to abut the strip and effect the seal. The U-section is non-magnetic and the bar (5) is guided by transverse dowels (13) fixed between the U-section legs and passing through bar slots. Blade springs within the slots maintain the bar in an elevated rest position so that the bar moves downwards against spring force. A further longitudinal blade spring on one leg of the U-section maintains the bar (5) in contact with the opposite leg.

Title: Phosgene mfr. by reaction of carbon monoxide and chlorine - in two stages, half the chlorine being added at each stage
Inventor: DOUBOVETZKY SERGE
IPC: C01B32/80
Filed: 1975-01-08
Abstract: Phosgene is made by vapour phase reaction between Cl2 and CO at 50-400 degrees C and 1-10 (3-7) bars pressure in the presence of C by passing the reactants over >=2 successive catalyst beds, with the whole of the CO introduced at the level of the first bed and part of the Cl2 being introduced at each bed level, the molar ratio CO: Cl2 being >1:1 pref. 1-1.1:1. A reaction completion step may be included in the process, to ensure a Cl2 content in the phosgene 200 ppm. The prod. is used in mfr. of isocyanates for prepn. of polyurethanes. The excess CO passing through the first bed acts as carrier gas, and coolant, so that the exothermic heat of reaction is controlled without the use of a separate carrier gas which is lost, or a by-prod. gas which has to be removed.

Title: Sea swell and wave energy convertor - uses displacement of multitude of floats to pump pressurised seawater into turbines
IPC: H02K7/18
Filed: 1975-03-17
Abstract: The seal swell and wave energy converter is used to produce electricity by harnessing the powerful mechanical forced produced by a moving mass of water such as the sea. The floating electrical power station consists of an enormous raft which is supported by a large number of floats, which can be displaced in a vertical direction. The displacement of the floats produces the pumping of a volume of sea water with a pressure equivalent to the volume of each float enveloped by a mass of water. Considering the case where only one out of two pumps is working at a given instant, the result is that an enormous flow of high pressure liquid is directed towards the inputs of a Pelton wheel or similar turbine. The mechanical energy produced by this turbine is used to drive an alternator. Connections to the mainland are made by submarine electrical cable.

Title: Rapidly erected building structure - with vertical walls constructed by uprights concreted into ground and against which perforated metal sheet is laid
IPC: E04B2/84
Filed: 1975-04-30
Abstract: Each metal support-upright is T-shaped, with the bottom end fixed in concrete poured into a cavity in the ground. The two support uprights are joined together by horizontal steel wires or cables forming a vertical sheet. The wires have loops looped over each upright so that two vertical wire sheets are formed. A perforated metal sheet is hooked onto each sheet. Each perforated metal sheet is bent at right angles round each T-shaped support upright so as to form shuttering for a mortar pillar. The metal reinforcement of the pillar is formed by the T-shaped upright. The shuttering of the pillar is formed by two perforated metal-sheet sides at right angles to the crossbar of the T. Between two support uprights are one or more secondary uprights fixed at the bottom in a reinforced concrete girder.

Title: Dishwasher operating method - uses guidance control to ensure cleaning liquid passes through fine mesh filter only prior to final rinse
IPC: A47L15/42
Filed: 1975-04-30
Abstract: Dishwasher operating method uses a processing stages where cleaning liquid is applied by a pump to rinse the dishes to be cleaned with a filter fitted to remove dirt rinsed out by the cleaning liquid before it is supplied to a spraying device. The liquid guidance system can be controlled to ensure that the cleaning liquid moves through a fine mesh filter only during its circulation before the last rinsing operation for the purpose of removing all dirt particles. The control of the liquid guidance through the fine mesh filter is carried out by the programmed switching unit, which simultaneously controls the supply of the clear rinsing additive.

Title: Press for dried agricultural products - is provided with heater coil to facilitate removal of pellet which is stuck
IPC: B30B15/34
Filed: 1975-06-25
Abstract: If a pellet becomes stuck in a press, e.g. when continuing the pressing process on a following day, time is lost in removing the pellet. To facilitate this removal, a heater coil (14) is placed over the cylinder (10) of the press. The heater coil can be placed either directly over the press cylinder or it can be mounted on a sleeve which is then placed over the cylinder. Alternatively, the heater is mounted on a split sleeve which is then clamped on the press cylinder. The cylinder will expand due to the applied heat, this will allow the ram of the press arrangement to eject the pellet.

Title: Drainage or watering layers construction system - uses sprays of chemically reacting or physically coacting with soil components (NL140676)
IPC: C09K17/00
Filed: 1975-12-09
Abstract: The system is intended for preparation or construction of drainage or watering layers and employs spraying or injecting at least one substance into the soil on the selected site and along the exact lines for the drainage or watering layer construction. This substance reacts chemically with one or more of the naturally occurring soil components or physically interacts with them in order to increase the permeability of the soil in the watering or drainage layer region, and thus to increase the capacity of the soil to remove surface water. Preferably a potential gradient is applied to the injection zone in order to accelerate or assist the chemical reaction or physical process. Pressure or force may be used for this purpose, possibly as a shock wave.

Patent FR-2336310-A1 (FR)
Title: Packaging and transporting method - uses beams supported under load by booms, spaced to allow lifting
Inventor: PERNOT JEAN DELPHIN
IPC: B65D19/40
Filed: 1975-12-22
Abstract: The packaging method consists of placing two rigid beams underneath the load, of sufficient depth and spacing to allow the load to be lifted by a fork-lift truck. The beams are secured to the load by hoops. This is the reintroduction of an old method of handling loads because the commercial use of standardised palettes leads to unnecessary increases in storage, recycling and book-keeping costs and certain shops have not got sufficient storage areas which makes additional difficulties for them. Adoption of this method of packaging for transportation will remove these inconveniences.
