Title: Beta-alumina ceramic articles - isostatically pressurised at high temp. and during cooling for increased durability as solid electrolyte
Inventor: JONES IVOR WYNN
IPC: C04B35/645
Filed: 1978-05-17
Abstract: A beta-Al2O3 ceramic article is mfd. by (a) compacting finely divided particles of beta-Al2O3 or materials reacting to form beta-Al2O3 to form a homogeneous green compact, (b) sintering to form an impervious polycrystalline ceramic, (c) isostatically pressurising at 1200-1550 degrees C. at >5000 p.s.i. (d) cooling under pressure to 1200 degrees C. and (e) releasing the pressure. Pref. sintering is by zone sintering, the green compact passing through a tubular furnace at a rate such that each part of the article is in the sintering zone for 12s-2 min. Air is passed through the furnace in the same direction as the article to carry volatile constituents through the furnace with the article, maintaining an Na2O-rich atmos. in the furnace, to form an impervious, fine grained polycrystalline ceramic having uniform density >3.2 g/cm3. The pressurisation-cooling treatment increases the durability of the beta-Al2O3 when used as electrolyte in NaS cells. Test results indicate that the likelihood of the cell surviving 1000 cycles is increased by a factor of at least 3.

Title: Vehicle IC engine ignition system circuit - has ignition switch whose OFF position prevents further electric ignition steps
Inventor: LUDWIG ALBRECHT
IPC: F02P11/02
Filed: 1978-07-01
Abstract: The circuit is connectable to the existing vehicle engine ignition system. The ignition switch (40) connects the ignition coil to a voltage source, and the system includes an alternator whose output voltage is used for self-regulation on one hand and on the other hand as a feed for the ignition coil.

Title: Safety mirror of glass bonded to reinforcement - has backing of rigid foam or steel framing the glass
Inventor: ROTH ECKART
IPC: A47G1/00
Filed: 1979-03-03
Abstract: The hindmost of three layers forming a safety mirror is a rigid plate of splinter-proof material. The front layer is a glass plate, silvered on its rear surface, and a layer of adhesive material bonds the two others together. The glass plate is enclosed by a frame formed integrally with the rear plate. The rim of this plate may only extend to the level of the front face of the glass or it may overlap it slightly. The rear plate may be of metal, e.g. steel, or it may be of rigid synthetic foam or of a permanently-setting synthetic resin, which may also have a reinforcement. The middle layer may be formed by a film which is adhesive on both surfaces. The safety mirror has the advantages that not only is the likelihood of its being broken less, but also, in the event of its being broken, the absence of detachable or loosened splinters reduces considerably the risk of accidental or intentional injury.

Title: TV receiver switched mode power supply circuit - includes HF conversion of mains by regulated transistorised prim. circuit
Inventor: OHE WILFRIED VON DER
IPC: H02M3/335
Filed: 1979-03-17
Abstract: A transistorised switched mode power supply circuit for a TV receiver prevents the mains being connected directly to the chassis or any part of the receiver and so making safety and aerial isolation easier and more effective. The circuit uses a mains rectifier (1) to feed d.c. through a resistor (2) to a switching transistor (3) completing the circuit through the primary (4) of the isolating transformer (5). The switching operation of the transistor (3) controlling current flow through the primary (4) induces current in the secondary (6) which is rectified (7) and smoothed (8) to power the receiver's circuits. The switching transistor is operated by its base circuitry (iB) connected to the incoming mains via resistor (16) diode (15) and capacitor (17) and with a control loop through a primary winding (9) with diode (10) and resistive (11) loop so that the switching is free wheeling but with timing control for stabilisation of the output (U1) through a further primary winding (12) and transistor/zener combination (13).

Title: Rotary anode X-ray tube - has tubular anode shaft opening into tube chamber and sealed from outside to increase load capacity
Inventor: SCHLEE KARL-HEINZ
IPC: H01J35/10
Filed: 1979-05-25
Abstract: Increased load capacity of a rotary anode X-ray tube as well as improved reliability and smooth running at high speed are due to the centre of he anode connected to outer ball bearing race by a tubular shaft. The inner race of the bearing is held by tube (19) acting as a pump connector through its opening into the tube chamber while vacuum-sealed from abienace. It facilitates the evacuation of the tube while the use of the copper for the tube simplifies fabrication. Improved cooling is achieved by use of a heat sink of carbon of zirconium-graphite which additionally acts as a getter for gas absorption. The graphite layer (17) of anode disc (16) decreases the thermal load of local point trajectories (12, 13).

Title: Cracked gas cooler decarbonising - by flushing in two stages at rising flow-rate with air and steam mixt.
Inventor: LOHR BERNHARD DR ING
IPC: C10G9/16
Filed: 1979-06-08
Abstract: Appts. for the thermal cracking of hydrocarbons is decarbonised by continuing to pass a cooling medium through the cracked gas cooler. In a first decarbonising stage, a gas stream of steam and O2 is passed through the cracking tubes and the cracked gas cooler at such a rate that the temp. of the deposits on the heat exchanging surface of the cracked gas cooler is within the range existing during the thermal cracking. In a second process stage, the gas stream is intensified to such an extent that the temp. of the deposits is raised. This reduces both the time and the cost for the decarbonising of the appts. Sepn. of the cracked gas cooler and allowing it to cool down is no longer required.
