Title: Electrode circuit for alarms, indicators and automatic switches - has thyristor extending negative potential to lamp, hooter, and relay with protective diode
Inventor: GREISINGER ELISABETH
IPC: H03K17/72
Filed: 1978-11-27
Abstract: An electrode circuit consists of a thyristor (1), a load resistor (2), voltage supply terminals (3, 4) electrode terminals (5, 6) and regulated output (7). The electrode terminals (5, 6) are coupled at a relatively low ohmic value either through a direct short circuit e.g. a mechanical switch (8) or conductive fluid, or via external electronic etc. monitoring circuits (8). The thyristor (1) is thus switched through. The negative potential is extended to the output (7) and the lamp (9) relay (10) with protective diode (12) for the thyristor (1), and hooter or buzzer (11) are switched on. The diode (12) can be directly integrated in the electrode circuit and the relay (10) directly switched on without thyristor-damaging voltage peaks arising. The circuit is esp. for alarms, eg water, anti-theft, gas, niveau indicators, twilight switches, rain sensors etc.

Title: Welding electron beam exit seal - with vacuum chamber of several collapsible segments
Inventor: ANDERL PETER ING GRAD
IPC: H01J37/301
Filed: 1979-01-22
Abstract: A beam exit seal for charge carrier (electron) beam welding, e.g. for the butt welding of tubes, consists of an annular chamber of U-section which is applied vacuum-tight against the inner wall of the joint and can be evacuated. The chamber is assembled from at least two(six) segments which form a tight joint at their ends and can be retracted radially inward before withdrawal.

Title: Bio-technical loop reactor - with baffle plates to divert gas bubbles away from descending liquid channel
Inventor: VOESTE THEODOR DIPL CHEM
IPC: B01J10/00
Filed: 1979-01-25
Abstract: A loop reactor to perform biotechnical reactions has several parallel vertical walls or tubes in which the liq. circulates separately in an ascending and descending stream. The gas which is introduced in the ascending stream is prevented from entering the descending stream by an array of inclined baffle plates which direct it to the liq. surface. This accelerates the liq. circulation and makes the heat distribution in the reactor more uniform. The overall efficiency is improved.

Patent DE-2918182-A1 (DE)
Title: Weft guide channel for airjet loom - having varying cross section with wider section alongside jet orifices
Inventor: SCHEFFEL WALTER
IPC: D03D47/30
Filed: 1979-05-05
Abstract: In an air-jet weft insertion device, a guide-channel is formed from a series of constrictors which are open on the side facing the reed, the size of the constrictor opening varying regularly to produce a saw-toothed bottom edge to the guide channel. Air jets are spaced regularly across the width of the loom between the reed and the constrictors, with the orifices in a plane perpendicular to the channel axis, and opposite the widest channel sections. The axes of the jets are inclined upwards and inwards to converge with the axis of the channel, at such an angle that the jet streams do not intersect the envelope of the guide channel on the side adjacent the jets. The arrangement of constrictors and jets avoids the formation of eddies between the lower sections of constrictors which would promote collections of fly large enough to interfere with weft insertion. The proposed system is efficient and reliable and permits the use of yarns previously unusable because of excessive fly production.
Patent DE-2921176-A1 (DE)
Title: Extruded clay strip stamping mechanism - has tools with ridges in line with parting positions in strip
IPC: B28B11/08
Filed: 1979-05-25
Abstract: The stamping mechanism is for a machine parting horizontally extruded and particularly rectangular-section clay strips in a plastics state, the strip being transported over a cutting table while a cutting wire is passed vertically through it and travels with it. Before the parting operation a taper-section roller turning freely on a horizontal axis forms notches in the strip sides where the cuts are to be made. One or more working strokes before the parting stroke a stamping tool is pressed against the top and bottom of the strip, travelling with the strip and at the same speed. Each tool has profiled ridges penetrating into the clay in line with the planes where parting is to take place.

Title: Vehicle IC engine carburettor - has vacuum operated servo coupled via slotted rod to choke flap and idling cam
Inventor: DIRDA JOHN
IPC: F02M1/10
Filed: 1980-02-29
Abstract: The engine carburettor has a choke flap upstream of the fuel jet in the intake passage and turning under the effect of temperature and the intake vacuum, while downstream of it is a driver-operated throttle butterfly. A lever on the spindle of the latter has an adjustable idling stop working against a cold idling cam with lobes of different heights, swinging under gravity into the inoperative position. This holds the butterfly at different settings for idling when starting, fast and slow idling when cold, and normal idling. A servo actuated by the intake vacuum opens the choke flap partly immediately the engine fires and runs, and then swings the cold idling cam from the highest cold-start position to the next one for fast colding idling. The servo (120) comprises a diaphragm (130) clamped between two housing sections (122, 124) so as to form a first chamber (132) subject to atmospheric pressure and a second (134) to the vacuum.

Abstract: Waste industrial gases contg. formaldehyde are continuously washed in a first zone by a circulating aq. soln. of hexamethylene tetramine and NH4OH with added NH3 which keeps the tetramine content at 20 wt.% or more. From subsequent zone(s) using water washing where circulating water has max pH 12, pr part of the second soln. is returned to the first zone, and part of the first zone soln. is intermittently or continuously extracted from the system. The enthalpy of the waste gases is held at a max. 43 (pref. 40) Kcal per Kg of dry gas by cooling before entry or by water in the first zone, and their saturation temp. held at 40 deg. C max. Used e.g. for waste gases from manuf. of plastic coating materials and reduces formaldehyde more reliably than with parent patent to the legal max. content of 20 mg/Nm3. The amt. of extracted waste water is small.

Title: Explosive bonding of tubes in tube plate - by charge expanding tube into stepped bore
Inventor: HAMPEL HEINRICH DR ING
IPC: B21D39/06
Filed: 1980-04-21
Abstract: A tube is fixed with its ends in a tube plate by explosive bonding. A stepped bore in the tube plate has one part with a smaller diameter and the other part with a larger diameter than a turned-down tube end. An explosive charge is inserted partly in the first part of the bore and into the tube and ignited. The progressive explosion pressure wave expands the tube end and welds it to the tube plate. This produces a 100% tight welded joint for any combination of materials and leaves no clearances where corrosion may set in. The weakening of the tube plate is reduced to a minimum.
