Title: Fire protection system for IC engine - has hydraulically controlled shutter to shut off engine air supply
Inventor: BAUGIER JEAN-PIERRE
IPC: F02D17/04
Filed: 1978-12-28
Abstract: A fire protection system for an engine consists of a shutter (1) which can shut off the air supply. It is normally held open by a bolt (5) engaging a catch (4). The bolt (5) is supported by a hydraulic cylinder (6) supplied with pressure from a pump (8). In the event of a dangerous rise in temp., a thermal sensing device is used to transmit a signal to an electronic circuit which cuts off power to the solenoid valve (12). This, in turn, shuts off oil pressure of the cylinder (6), releasing the bolt (5) and so shutting off the air supply.

Patent DE-2921748-A1 (DE)
Title: Focussed pulsed laser beam - directed on water improves its radioactive shield function
Inventor: BUDWIG GEB BUDWIG JOHANNA DR
IPC: C02F1/00
Filed: 1979-05-29
Abstract: The Parent Patent No. 2936094 described a method of using water as a protective shield against the damaging effect of radioactive radiation. The energy level of the electrons in water is raised higher if a focussed laser beam, preferably from a red ruby laser is directed on the water. This improves the resistance of the water electrons to the destructive radiation of radioactive elements. Apart from the protective action, laser beams can also be used to regenerate radioactively contaminated water to reduce the radiation level to a biologically acceptable figure.

Title: Failure warning switch for dual circuit braking system - has double piston between circuits which is moved by differential pressure when one circuit fails
Inventor: REINARTZ HANS-DIETER
IPC: B60T17/22
Filed: 1979-07-21
Abstract: The warning switch for a vehicle twin circuit braking system has two connections (15,16) for the two sections of the braking circuit. The two connections are at the inlet ends of two cylinders (11,14) containing pistons (12,13) which meet at a central point (19) when the pressure is equal in the two sections. Above the central point is located a plunger (22) with a diaphragm (32) resting on it. When one circuit section fails, so that there is no pressure in that half, pressure in the other half pushes the two pistons sideways so that a sloping part (20,21) lifts the plunger. This raises the diaphragm and a collar (31) on which it is mounted, against the force of a spring (33) and enables contacts (34) mounted on the diaphragm to close a warning circuit. The cover (26) over the spring can be returned manually to re-open the switch contacts.

Inventor: SIRTL ERHARD PROF DIPL CHEM DR
IPC: C01B33/02
Filed: 1979-11-08
Abstract: Pure silicon is obtained in a cyclic process by reducing quartz sand with aluminum; the finely divided quartz is dissolved in an aluminum sulphide slag and is reduced by molten aluminum. The molten aluminum also serves as a solvent for the elemental silicon which crystallizes out and precipitates as the temperature falls. Aluminum oxide formed during the reduction is extracted from the slag and passed on for melt electrolysis in order to recover the aluminum.

Title: Ring-brominated di:- and multi-ring aromatic cpd. prepn. - by adding cpd. to be brominated and bromine part to reaction medium contg. remaining bromine
Inventor: JENKNER HERBERT DIPL CHEM DR
IPC: C07C17/12
Filed: 1979-12-18
Abstract: Opt. halogen-substd. two- or multi-ring aromatic cpds., (I), are ring-brominated by reation with Br2 in an inert reation medium in the presence of a halogenation catalyst. Novelty consists in (i) charging a reactor with 2-90 wt. % of the total Br2 quantity theoretically required for reaction, in part or all of the reaction medium and with a part or all of the catalyst, and (ii) adding (I) to be brominated together with the remaining Br2 quantity and opt. balance of reaction medium and catalyst. The catalyst can be a Lewis acid, esp. ALCI3 or ALBr3, and/or 12. The stoichiometrically required Br2 quantity can be halved by working with BrC1 or a 1 : 1 molar mixt. of C12 and Br2. Pref. total Br2 quantity is 100-120 wt. % of the theoretically required Br2 quantity for the desired degree of bromination. The reaction takes place esp. at 0-80 (10-40) deg. C. The ring-brominated prods., (A) are used as flame-retardants for plastics, esp. ABS-polymers. Weekly-coloured, pure (A) is obtd. in yields over 90% of theoretical. Br2 losses are reduced and reaction-times are short. The desired degree of bromination is achieved, lower than the max. degree of bromination.
