Chatter is suppressed in a solids-liquid separating centrifuge by including, in an external connection to a holder of the speed change gearing between the centrifuge bowl and conveyor, a spring and mass means which is torsionally resilient about the axis of the connection such that it will vibrate about that axis under chatter conditions at the chatter frequency, and which has a spring rate within...

Highly soluble complexes of 2-(4'-thiazolyl)benzimidazole are prepared using glycolic acid. The aqueous solutions prepared therefrom are stable and may be used for anthelmintic and antifungal purposes. Additional compounds, especially other fungicidal agents, may be combined for compositions of broad spectrum.

The present invention relates to a process for the preparation of phenol-formaldehyde foams by mixing a resol phase having a viscosity of between 8 and 60 poises and a novolac phase comprising a true novolac, a blowing agent, phenolsulphonic acid and, optionally, phenol, the relative amounts of resol phase and of novolac phase being such that the resol phase represents 45 to 75% by weight of the m...

A hazardous ammonium jarosite based sludge is solidified by the addition of cement and fly ash under mildly basic conditions, pH 10+/-1.5. The ammonia does not have to be driven off prior to solidification.

The housing parts (6; 12, 13), which contain the end (9) of the supply lead and the terminal parts of the jacks (8) in subdivided accommodating chambers (7), are configured in the manner of half-shells (12, 13). The latter are mutually anchored by means of a hook-in connection (22, 24; 23, 25) which is active in the region of the entry fitting. A front part (1) of the connector containing the cont...

A conversion circuit 20 for use with digital telephone switching equipment for converting pulse amplitude modulation (PAM) signals on line 19 into pulse code modulated (PCM) signals on line 31 and for converting PCM signals on line 30 into PAM signals on line 18. When these conversions are done it is desirable to adjust the magnitude of the signals involved to take into account the differing losse...

The invention relates to an induction heater for heating annular articles, and includes a U-shaped transformer core (1) and a magnetic yoke which can be lifted from the transformer and upon which the article to be heated can be fitted. When heating the article, mains current is supplied to a primary core (2) on the transformer core, via a first switch (4). In accordance with the invention, the swi...

PURPOSE:To make a shock absorber compact in size and light in weight, by setting up a pair of them in the lower part of an X-shaped link. CONSTITUTION:Springs 12 are parallelly installed in the upper part of an X- shaped link 3, and engaged tight with both of an upper end 5a of the X-shaped link 3 and a bell crank 14. Another end of the bell crank 14 is linked up with a nut 21 of an adjusting shaf...

PURPOSE:To enable to perform excellent combustion even under a condition in which oxygen is in low concentration, by a method wherein uniformizing region, each of which is gradually decreased in width toward the central part in the longitudinal direction of a burner port surface, and reinforcing bands are attached in a flow uniformizing chamber located above a pressure uniformizing chamber, and pr...

PURPOSE:To obtain a space light modulator which is small in size, is usable at a high speed and is suitable for a laser printer by forming the modulator in such a way that the space between the metallic surfaces of the piezo-electric elements from the base of a prism can be changed in accordance with the signal impressed to the piezo-electric elements. CONSTITUTION:A piezo-electric block 6 which i...

PURPOSE:To improve the operability of an NC device by displaying the prescribed numerical control information on an automatic programming picture in an automatic programming mode. CONSTITUTION:In an automatic programming mode, a processor 106b stores the character code data showing the numerical control information into a memory area 106d-3 of an RAM106d and then reads out this information success...
