Patent DE-4214747-A1 (DE)
Title: Flange connection with seal between two outer flanges - has threaded bore in at least one flange to take force screw for supporting counter flange
Inventor: LENK GUENTER
IPC: B25B27/16
Filed: 1992-05-04
Abstract: The threaded bores are made during or after production of the flanges. Before the component containing the counter bore is fitted the force screws (4) are turned into the threaded bores so that the load arising from the top or side is supported with the counter flange on the force screws. Only one threaded bore is required for flanges with diameters up to 200 mm but three bores are provided where the diameters are from 200 to 800 mm. The support face of the force screw is formed by a disc (6) which adjoins the end face of the screw shaft and can rotate relative to the shaft. During fitting the flanges are aligned with each other by guide pins (7) after the seal is inserted and the counter flange is fitted on the screw. The force screw is then turned out from the flange so that both flanges (1,2) are brought together. USE/ADVANTAGE- For heat exchangers, reactors and other containers where damage to the intermediate seal must be avoided.

Title: Periodic half-wave suppressor for AC-fed load e.g. incandescent lamp - reduces wasteful dissipation of power by supplying selected half-cycles directly or via step-down transformer
IPC: H05B39/08
Filed: 1992-05-05
Abstract: Two lamps (L1, L2) of an array are switched (S1, S2) directly to the AC supply, and the third (L3) is supplied with lower voltage from a switched-prim. transformer (TR). The switching circuit controls the sequence of illumination while the suppression circuit (H) periodically cuts-off individual half-waves of the AC waveform or gps. of half-waves. Either odd or even numbers of half-waves may be either suppressed or allowed to pass through the circuit for application to the AC load. USE/ADVANTAGE - Esp. for traffic signals, lamp lifetime is prolonged and average power consumption reduced.

The yield of triester was almost quantitative. (B) 100 pts. of steeped, delimed oxhide was soaked in a 50% bath contg 2% of the ester from (A), at 30 deg. C. After 30 mins., the pH was 8.9 and the H2S concn. was 140 ppm. After a further 60 mins., the hide was delimed, the H2S concn. was O and the pH was 9.2. The hides were clean and bright. Further treatment gave a soft, evenly dyed leather with very fine grain.
