Title: Device for epitaxial growth from gaseous phase - has inner tube for waste gas extn. and annulus for flushing gas
Inventor: WILLIG WOLF RUEDIGER DR
IPC: C30B25/14
Filed: 1977-09-29
Abstract: Device for the growth of epitaxial layers from the gaseous phase consists of a quartz tube, surrounded by a source of heat, sealed at the upper end by a gas feed module and at the lower end by a rotatable inner tube. The inner tube, which is axially movable and can be rotated, acts as a substrate holder. It is also used to extract waste gases and forms with the quartz tube an annulus which is connected to a flushing gas supply. The deposition of by products (GaCl, P, As) of the reaction on the inside of the quartz tube, which otherwise have to be removed by a wet chemical process, with the risk of contamination of the epilayers and of thermal stresses in the quartz tube, are eliminated.

Title: Industrial steam iron ensuring greater efficiency and durability - has control circuit outside iron readily available to operative
Inventor: DOKOUPIL JIRI DIPL ING
IPC: D06F75/24
Filed: 1978-01-11
Abstract: Bimetallic contact temp. regulators are dispersed within an industrial steam iron, so that the problem of their relatively short working life, and the difficulties of their subsequent adjustment are overcome. The redesigned iron can be switched off without altering the set temperature, and when switched on again, it quickly and accurately raises the temp. of the sole to that set previously. A signal lamp is fitted to the main switch. In the sole of the iron is >=1 NTC resistance, the conductors for which run alongside those or the heaters, or are assembled with them as an at least five pole cable. The conductors are connected via a plug and socket to a control circuit in a housing outside the iron, but convenient for the operative. A thumbwheel for a potentiometer or contacts for separate resistance steps is located on the housing.

Title: Hydrogen chloride detector using lightweight cassette indicator tape - is used for detecting gas released by overheated or burning PVC
Inventor: HARI PETER DR
IPC: G01N31/22
Filed: 1978-09-13
Abstract: Appts. for detecting HCl released by excessive heating or burning of materials contg. PVC has a housing with drive contg. cassette(s) of tape provided with an indicator, which changes colour on exposure to HCl. The cassette has opening(s) connected to the outside air. The novel feature is that the wt. of the tape is =6(2-3) mg/cm2. Appts. is useful in fire protection, e.g. of stored goods, floor coverings, electrical insulation etc. contg. PVC and for protecting plant, machines and steel-reinforced concrete structures against corrosion by HCl, which often leads to greater losses than actual fire damage. The response time and operating time of the cassettes is improved, since much less HCl is needed for the colour change and a longer tape can be inserted in the cassette.

Title: Semiconductor push-pull output stage circuit - has transmitter with two primary windings, symmetrically connected to supply feeding semiconductor device
Inventor: GANSNER BERTHOLD DIPL ING
IPC: H03F3/26
Filed: 1978-10-11
Abstract: The semiconductor push-pull end stage has a sonar-amplifier. Four conduction transistors, serve, as switches (1-4) and are connected in pairs to the primary windings (5, 6). The DC supply voltage UB feeds a supply circuit. The diodes (7-10) act as voltage limiters and are set parallel to the switches (1-4) and the corresp. primary winding. The secondary (11) of the same transmitter feeds the output voltage UA. A switching cycle is then initiated. The switches (1, 2) are simultaneously set in a closed position, thereby passing a current I1 through the primary winding (5). The current I1 induces a voltage in the neighbouring windings (6, 11), which is regulated in the winding (6), such that the applied potential to the switched (3, 4) approximates the DC supply voltage. In the next half-period, the switches (3, 4) are closed and switches (1, 2) open. The output current I2, irrespective of the output voltage, induces in the first primary coil (5) a load voltage, whose max value corresp. to the supply voltage.

Title: Solid insulation for cable jointing box - is split into two, longitudinally, and has sleeved joints between parts
Inventor: HOLLAND KARLHEINZ
IPC: H02G15/103
Filed: 1979-07-27
Abstract: The insulation design for use in cable joints eliminates the need for taping. A solid dielectric forms two sections of insulation (4,10) extending over the required length for the joint (8). The sections are joined longitudinally. The joins are in the form of a spiral each extending over at least 60 degrees, and pref. 90 degrees, of the circumference, and fitting together to form a sleeve. When the insulation is fitted over the joint a shrinkable sleeve (6) is pulled over. When fully contracted the pressure exerted by the sleeve holds the joints in the insulation sections in intimate contact to give a very high resistance creep path. The inner and outer surfaces of the insulation sections are normally covered with a semi-conducting layer (7,9;5,11).

Title: Radar and Doppler measurement of speed and distance travelled - using reflective material along stretch of rail to avoid gaps in signal pick up from rail vehicle
Inventor: LINKE ROLAND DIPL ING
IPC: G01S13/60
Filed: 1979-10-24
Abstract: In order to measure the speed or distance the tracked vehicle has travelled, a marker is arranged at the beginning of the stretch which is registered by the vehicle. From this marker, up to the destination, and along the entire length of the track which is radiated by the antenna on the vehicle, and from which the preponderant share of the reflected Doppler signal comes, a material is laid which gives rise to a symmetrical reflection of the radar system signal transmitted from the vehicle. In this way, deviations caused by unevenness of the surface are avoided, guaranteeing an exact measurement of distance due to there being no gaps in the reflected signal. This method also enables very low vehicle speeds to be measure accurately.
