Title: Composite filter unit with electric heating element - which has heating mat mounted between frame and gas adsorption filter
Inventor: ECKSTEIN WOLFGANG
IPC: A62B13/00
Filed: 1975-11-29
Abstract: Heating device for composite filter units uses an electrical heating mat with a surrounding frame which is mounted between the outer frame and the gas filter. The mat is held by its frame against the outer frame. The surrounding frame is made from a flexible heat resistant material. It can also have a drawn down surrounding edge. For use in filtering air and other gases to remove dust and other harmful components. This is done in two stages a dust filter and a gas filter. The first is generally a woven cloth element and the other an activated carbon filter. The efficiency of these is affected by the relative humidity of the feed gas. This can be reduced by warming the air. However if the heater is in front of the fabric filter it becomes fouled up. The system avoids fouling of the fabric filter but allows maintenance of the heater after use.

Title: Cooling liq. lithium coolant of fusion reactor - by bubbling helium through lithium onto containing walls
Inventor: MORI YASUO PROF
IPC: G21B1/13
Filed: 1975-12-05
Abstract: A method of removing heat from a nuclear fusion reactor consists of blowing helium bubbles directly into the liq. coolant, esp. liq. Li metal, of the reactor and thus removing the heat directly from this coolant. Pref. the helium coolant is blown directly against the vacuum wall and the wall surrounding the liq. coolant. By blowing the helium directly into the liq. Li, the need to circulate the Li transversely through the very strong magnetic field is eliminated. At the same time, the advantage of Li metal cooling is retained, esp. that of tritium breeding.

Title: Seat belt lock with illuminated release button - has built in acoustic reminder signal for set period when belt not in use
IPC: A44B11/25
Filed: 1976-01-30
Abstract: The seat belt lock has an illuminated release button and acoustic signal which sounds as long as the user does not put on the belt. The circuit activates the acoustic signal when the ignition is switched on and reminds the user to put on the belt. If the user decides mot to use the belt, a bimetal switch breaks the circuit after a certain time. The circuit can be fitted with an impact-operated device, which in case of an accident switches on ths signal again in order to alert the rescuers to release the belt for freeing the injured person. The illuminated release button is switched on when the car lights are switched on. The device can be also activated by a pressure switch in the seat responding to the weight of the user.

Title: Automatic tuning of flexure oscillator during manufacture - is adjusted by vaporising material from surface of oscillator by laser beam
Inventor: MATTELIN ANTOON DIPL ING
IPC: H03H3/013
Filed: 1976-05-28
Abstract: The frequency of a steel flexure oscillator or resonator is automatically adjusted during manufacture to achieve a predetermined nominal frequency. A high energy laser beam vapourises a calculated quantity of material from the front face of the oscillator to obtain the desired frequency. The flexure oscillator is clamped such that material can be removed from its front face by a beam from a laser. A measurement laser which controls galvanometer motors via a processor ensures a predetermined vaporising zone is presented to the laser beam. Correct frequency is obtained automatically by sensing oscialltion frequency by microphones and applying these signals to the processor for calculation of target area and duration of laser shot.

Title: Cupboard unit for corner - has two covers connected by levers so that movement of one causes other to slide over
Inventor: STALDER FRITZ
IPC: A47B81/00
Filed: 1976-07-30
Abstract: The first cover unit is fitted to pivot on a runner rail. The runner rail is fitted to the base unit by a vertical hinge. A roller on the runner rail runs along the guide slot in an angled lever. This angled lever pivots round a point on the base unit whilst its free end is connected to a second lever whose end pivots round a point under the second cover unit. When the first cover is lifted out of its position and swung round the vertical hinge the runner rail swings with it. This forces the roller along the lever guide slot thus turning the lever so that the second lever draws the second cover unit into the free space left by the first cover to allow access to the corner cupboard. The cupboard is closed by reversing the process.

IPC: C30B13/32
Filed: 1976-08-10
Abstract: Plant for zone melting metals or semiconductors has a long vessel located in sealed chamber fitted with >=2 coolers; and >=1 high-frequency induction heating unit located between the two coolers. The vessel can be moved longitudinally w.r.t. the inductor. Each cooler is made of several elements which are mounted on the outside walls of the vessel, and are electrically insulated from each other and from the walls of the chamber, so each element is electrically separate. The cooling elements used on the sides of the vessel are pref. spring loaded so the vessel can be driven through the elements and also the inductor; and the elements pref. contain pipes through which a coolant flows, the pipes also being electrically insulated where they leave the chamber. Plant is esp. for zone melting metals with high conductivity, e.g., aluminium to make hihg purity ingots with a wt. >100 kg. in a chamber using vacuum or inert gas. The cooling elements are designed to minimise their heating by the inductor, which would retard the cooling rate of the ingot.
