Patent DE-3930033-A1 (DE)
Inventor: JACOBS CARL H
IPC: A61F2/00
Filed: 1989-09-08
Abstract: A prosthetic implant includes a base portion (10) and an additional portion (20) which is to be securely attached to the base portion. The additional portion (20) includes at least one post (32) extending therefrom which is adapted to be readily received in a corresponding reverse tapered hole (14) in the base portion (10). The post (32) is adapted to be mechanically spread out to cause at least a portion of the post to become wider than the opening of the hole (14), thus resisting subsequent separation of the post from the hole. This secures the additional portion (20) to the base portion (10) of the implant. The post (32) may be a stud-type extension integrally formed with or secured to the additional portion (10), or the post may be a separate chamber which is received in a post hole in the additional portion such that the post portion of the separate member extends from the additional portion. The post may be solid or may have a channel therethrough. The additional portion (20) may include a substrate (26) with a porous surface (24) bonded or secured thereto. The spreading of the post may be effected by a protruding member (18) on the bottom of the hole (14) or by a separate plunger (50) forced into a channel (40) in the post. <IMAGE>

Title: WC cistern with two outlet valves - enables reduced quantity of water to be used if required
Inventor: AHRENS DETLEF
IPC: E03D1/14
Filed: 1989-09-28
Abstract: The WC cistern (11) has an outlet pipe (17) aligned with an internal valve housing (34) which has a seat (33) for a valve plate (31). The WC can be flushed by actuating lever which lifts the valve plate (31) off the seat (33).

Title: Reducing phosphor fault effect for reproduction CRT - uses cyclically repeated group of illuminating strokes and pixels instead of single illuminating stroke
Inventor: KUEN JACOB
IPC: B41J2/435
Filed: 1989-10-06
Abstract: On the CRT are formed sequential points and finitely large lines along a single imaging line, located always at the same position. The points and lines are focussed onto a photosensitive material by an objective lens. Between the CRT and the material takes place a translation movement. Instead of a single, useful illumination point line on the CRT, a cyclically repeatable group (0.7) of sequential strokes and pixels can be reproduced on the CRT (20, 22). They are of definite size and sequentially energisable in coincidence with the translation movement and the point to be illuminated on the photosensitive material. USE/ADVANTAGE - For photo typesetting machines. Improved CRT service life. No need for pre-testing, tubes with faults can be used, multiple strokes can be used.

Patent DE-4020656-A1 (DE)
Inventor: SCHROEDER ERNST DR ING
IPC: G10L25/00
Filed: 1990-06-29
Abstract: 2.1 In a method for transmitting a signal which is divided up by windows into consecutive, overlapping blocks, the partial signals contained in the blocks are in each case converted by transformation into a spectrum, the spectra are then coded, transmitted, decoded after transmission and converted through inverse transformation back into partial signals. Finally, the blocks containing the partial signals are joined in overlapping fashion, wherein the overlapping areas of the blocks are weighted so that the resultant of the window functions is one. 2.2 To prevent interference in adjacent blocks in the event of frequency changes, the window functions and the length of the window functions are selected according to the changes in frequency of the input signal. 2.3 The method is suitable for processing audio and video signals, which are subjected to data reduction in transmission. <IMAGE>

Title: In-situ regeneration of solid bed hydrogenation catalyst - involving washing in 1-4C alcohol, regenerating in nitrous oxide-nitrogen@ mixt. and activating in hydrogen@-nitrogen@
Inventor: GRITZ EGBERT DR
IPC: C07C29/149
Filed: 1990-12-24
Abstract: In-situ regeneration of de-activated solid bed hydrogenation catalysts is effected by (i) washing the catalyst charge with a 1-4C alcohol; (ii) treating the washed charge with an N2O/N2 mixt. at 110-200 deg.C; and (iii) activating the regenerated charge with an H2/N2 mixt. at 120-250 deg.C.
