Title: Excitation circuit for permanent magnet - has storage capacitor for de-excitation following mains interruption by triggering of diac connected to thyristor gate
Inventor: NESTLER WOLFGANG DR ING
IPC: H01F7/18
Filed: 1978-10-16
Abstract: The circuit finds application in magnetically operated tools were both high initial attraction forces and high residual magnetisation are required. A storage capacitor (8) charges during the excitation phase by cyclically switching a series thyristor (1). When fully charged the excitation phase ends and the thyristor remains off. The capacitor (8) then charges a reference capacitor (9) which is cyclically drained if the a.c. supply (20, 21) remains on. With the supply interrupted the reference capacitor potential reaches the break-over voltage of a diac (7) connected to the gate of the de-excitation thyristor (3). It triggers and a reverse current pulse from the storage capacitor is applied to the winding (18) resulting in demagnetisation.

Title: Phantom indication reducing system - uses screened oscillator, preventing oscillation of reflected pulses on specimen surface in ultrasonic testing
Inventor: RIES KARL ING GRAD
IPC: G01N29/24
Filed: 1979-04-24
Abstract: The phantom indication reduction is used in ultrasonic measuring systems, especially where particle dispersion in the coupling medium has a tendency to produce such indication, e.g. in a pulse-echo method for testing sheet metal, webs rods and tubes using normal test heads in immersion technique andoblique ultrasonic impingement. The ultrasonic oscillator is screened so that pulses reflected from the specimen surface do not reach the oscillar. Pref. the sonic field of the oscillator is surrounded by sound absorbing material from the oscillator up to the specimen surface. Thus the phantom indications are reduced and true indications, generated by the defect(s) are differentiated without using electronic methods.

Title: Fine-grained lime, dolomite, magnesite, etc. heat treated in hot gas - is subsequently fed into rising stream of pressurised cooling gas
Inventor: ABELITIS ANDRIS DIPL ING
IPC: F27B15/00
Filed: 1979-12-22
Abstract: In the thermal treatment of the material by a stream of hot gas followed by multi-stage cooling in colder gas which after it acquires heat is used as combustion air, this cooling gas is pressurised while in the hottest stages of the cooling unit. The heated material is sepd. from the hot gas stream and fed into the cooling gas in the latter's pressurised zone, which includes the last two stages of the cooling unit. To enter the cooling gas stream the hot solids must overcome a counter-pressure of 150- 500(250-300) mm. of water. The corresponding appts. includes a suspension type heat exchanger and pressurising fans. The system is economical in power consumption and has no mechanical units in the hot solids region.

Title: Reflux cooler esp. for vinyl chloride polymerisation - has externally corrugated plates with internal vertical ducts for coolant and provides accurate temp. control and high quality prod.
Inventor: GATTYS FRANZ JOSEF
IPC: F28D3/00
Filed: 1980-02-09
Abstract: A reflux cooler for recycled reaction gas associated with highly exothermic reactions in which foam is formed, is intended esp. for the prodn. of PVC. The heat exchange element used comprises plates corrugated or undulating on both sides and containing tubular chambers or cavities; these plates are freely suspended in a housing, a coolant being conducted through the tubular cavities, while the undulations on the external surface run vertically. The plates are pref. Al (at least 99.5% Al content) and are coated with an anti-corrosion coating on their external surfaces. The plates are pref. hung at spacings of 120-180 mm. Used for cooling the recycled gas in the polymerisation of vinyl chloride to provide accurate control of temp. and thus obtain high quality in the end product. By spacing the plates sufficiently far apart, i.e. at 120-180 mm, bridging across of material between adjacent plates is avoided, whereas the corrugated external form partly compensates for the resultant loss of cooling area per vol. Furthermore, the grooves of the corrugations promote the rapid downward flow of the condensate.

Title: Rod packing gland sealing ring - of coiled compressed strip with end edges running along curved lines
Inventor: KOBALE ERICH
IPC: F16J15/22
Filed: 1980-05-13
Abstract: The sealing ring is manufactured from graphited expanding strip material, wound into a coil and then compressed together. The ends (3,4) of the coiled strip material (5) are cut along lines which, between their intersection points with the outer edges of the strip (9,10), deviate continuously from straight ones at right angles to the lengthwise axis of the strip. They can be at less than 45 deg. to these edges, and of triangular, sawtooth or corrugated shape. The design gives an improved join between the strip ends and the material underneath, with less risk of the edges lifting off in use.
Patent DE-3040177-A1 (DE)
Title: Fibre layer separator remove aerosols and vapours - of low boiling hydrocarbon(s) by addn. of high boiling hydrocarbon(s)
Inventor: LEISEGANG LUTZ DIPL ING
IPC: B01D53/34
Filed: 1980-10-22
Abstract: Waste air from industrial processes contg. aerosols and vapour mixts. of low-boiling hydrocarbons is treated by sepn. on fibre layer separators. Simultaneously with the air, a higher-boiling absorption liq. is also applied to the fibre layers. In a variant, the liq. phase of the aerosols which are to be separated is used as this absorption liq. The absorption liq. may be regenerated by vacuum distillation. In particular in the plastics processing industry, where hydrocarbon mixts. are given off in the waste air and cannot normally be sepd. by fibre layer separators. It is found, that by applying a higher-boiling hydrocarbon, the lower-boiling hydrocarbons may also be sepd. The regeneration process is comparatively easy, since the lower-boiling hydrocarbons can be distilled at temps. of 30-100 deg. C and comparatively low vacuum.
