Title: Ignition system for IC engine with two electronic switches - has limiting diode for primary voltage and capacitor discharge for energy release
IPC: F02P3/00
Filed: 1979-01-17
Abstract: The ignition system is for an internal combustion engine, which has two electronic switches. One electronic switch is in series with the primary of the ignition coil and controls a current through the coil when switched on. The second electronic switch is triggered by a control coil. The second electronic switch is in series with the primary winding and a capacitor charged by a converter circuit. When switched on it discharges the capacitor through the primary winding. The voltage across the primary winding (5) of the ignition coil (6) increases to a value limited by a diode (20) to that of the charge capacitor (7) when the first electronic switch (9) is open. The current through the primary via the control coil (21) flows to the capacitor (7) via the diode (20). The flow is broken to release inductive ignition energy.

Title: Protective assembly for river bank - of PVC tubes forming piles cheaper and more easily driven than wood
IPC: E02B3/04
Filed: 1979-06-18
Abstract: Synthetic tubes' esp. of PVC having an inner wall and an outer wall joined by partitions which form channels running axially through them, are used in an assembly forced into the earth to protect river banks, dams, etc. The inside and the outside of the tubes are similar and the partitions form a whole with the tube walls. The channels are round in cross-section. The tubes are driven into the ground by pumping fluid through the channels from the top and out at the bottom end; pressure being applied to the tubes during this operation. Installation time is saved, since the tubes can be pressed into the ground much more easily.

Title: Terephthalic acid purificn. - by dissolving in water and then hydrogenating and recrystallising in presence of alkaline material
IPC: C07C51/487
Filed: 1979-06-20
Abstract: Purificn. of terephthalic acid (I) comprises dissolving crude (I) (obtd. by oxidising p-tolualdehyde with O2 in the liq. phase using water as solvent and a bromine cpd. as catalyst) in water, hydrogenating using H2 in the presence of a hydrogenation catalyst and recrystallising. Novelty is that hydrogenation and recrystallisation are carried out by adding an alkaline material. Highly pure (I) is produced easily by the H2 reduction in spite of using water as the solvent for oxidation, and it is possible to prevent the lowering of activity of the hydrogenation catalyst. Pref. p-tolualdehyde is supplied to water, contg. 0.8-10 wt.% of bromine ions, continuously and oxidised with O2 at 180-240 degrees C at a raw material supplying velocity of 0.1-0.35 kg/hr.l continuously. The obtd. crude (I) is sepd. and dissolved in water. After adding an alkaline material such as a hydroxide, carbonate or bicarbonate of Na, K, Ca, Ba, etc. to the soln. aq. (I) is contacted with H2 at 200-330 degrees C for 0.005-10 hrs in the presence of catalyst to obtain highly pure (I).

Title: Multicompartment vertical storage cabinet - can raise or lower banks of compartments using electrical motor for ease of access
IPC: A47B51/00
Filed: 1985-09-06
Abstract: The cabinet has a framework (1) consisting of three vertical plates, a top, base and rear panel. The central vertical plate divides the cabinet into two rectangular section columns. In each column is a bank (2,3) of compartments; the compartments being separated by shelves (6). The compartments are supported by a single cable (4), which runs over the central pulley of a tubular housed motor. The user presses one of two buttons to drive the motor, and to bring the required shelf to a height where access is easy. As one rack rises,the other is lowered, so that the main load on the motor is caused by any imbalance between the loads carried in the two racks.

Title: Mfg. elongated cavities in injection moulded plastic components - by injecting gas at pressure after initial cooling, to control wall thickness and produce enclosed or partially enclosed cavities
IPC: B29C45/17
Filed: 1990-11-14
Abstract: The mould cavity of a plastic injection mould tool contains an elongated chamber, a gas holding space filled with gas under pressure and a cavity for excess material. Both the gas holding space and the cavity are closed off from the mould cavity at the start of the moulding cycle. After initial injection of material into the mould cavity, the material is allowed to cool until a layer of plastic material has solidified along the wall of the elongated chamber. Gas under pressure is than injected into the still fluid material in the elongated chamber via an opening. Just after this injection, or at the same time, an expansion chamber is brought into connection with the opposite end of the elongated chamber by means of an opening. The fluid material inside the solidified wall of the plastic material in the elongated chamber (6) then flows under the action of the gas pressure into the expansion chamber resulting in an elongated cavity within the plastic component. The material is than allowed to cool further. The mould is opened and the connection between the gas holding space and the elongated chamber is closed. The prod. is removed and sepd. from the material in the expansion chamber.

IPC: C04B35/00
Filed: 1994-01-19
Abstract: This invention relates to a method of protecting magnetic powders and permanent magnets containing at least one rare earth, at least one transition metal and boron, against oxidation and atmospheric corrosion by introducing gaseous fluorine during the grinding of the powders. It is characterised in that the fluorine is introduced using a F2 + N2 mixture during the fine grinding of the powders, this mixture containing between 1 and 100 ppm (by volume) of fluorine, and preferably between 1 and 10 ppm. The powders thus obtained are markedly less reactive and the densified magnets are markedly more resistant to atmospheric corrosion than non-fluorinated powders and magnets obtained from the latter.
