Patent DE-3913905-A1 (DE)
Title: Closing device for electrical distributor cabinets
Inventor: ZENGER DIETER
IPC: H02B1/38
Filed: 1989-04-27
Abstract: A closing device for electrical distributor cabinets, especially cable distributer cabinets, consisting essentially of a lock 3 having a handle which is in the form of a lever and can be recessed and at whose free end a holder is integrally formed for a profiled half cylinder which inhibits the handle from being operated impermissibly in the recessed state, and having bolt parts 3A which are operatively connected to the lock 3. The key operating side (5A) of the profiled half cylinder (5) is arranged on the end (4C) of the free lever end of the handle (4). When the handle (4) is in the recessed position, the profiled half cylinder (5) is completely covered. In the partially recessed position, the handle is locked against pivoting out and rotation by means of the lock bit (5B) of the profiled half cylinder (5) which acts against a stop (2B) which is integrally formed in the region of the lock holder (2A). When the handle (4) is in the operating position, in which said handle (4) can be pivoted in order to operate the locking, the profiled half-cylinder holder (4B) emerges from the front side of the distributor (1). <IMAGE>

Title: Method and device for determining the diameter of cigarettes
Inventor: HEITMANN UWE
IPC: A24C5/34
Filed: 1989-05-16
Abstract: In order to determine the diameter of rod-shaped articles in the tobacco-processing industry, in particular of cigarettes and filter rods, the articles (19) are conveyed in an axially transverse fashion on a conveyor (16), and in so doing pass a light beam of a light barrier (14) which is aligned towards the conveying path of the articles. The duration of the passage of the articles through the light beam is detected, and a measurement signal is formed which corresponds to this duration. The measurement signal is used to generate a diameter signal representing the article diameter. Before passing the light beam, the articles (19) are rotated about their longitudinal axis by different, randomly produced angles by means of a rolling device (13). For the purpose of rotation, the articles are lifted from their support (18) by means of blast air from an overpressure source (24). <IMAGE>

Patent DE-4025434-A1 (DE)
Inventor: RECK ALFRED DIPL ING
IPC: B01J35/04
Filed: 1990-08-10
Abstract: A honeycomb body (50), in particular a catalyzer bearing body for exhaust gas systems of internal combustion engines, has channels (53, 54) through which a fluid can flow in a direction of flow. This body (50) is composed of a plurality of individual metal plates (51, 52), of which at least a part (52) has structures that extend parallel to the direction of flow, forming the channels (53, 54). The structures of at least part of these structured metal plates (52) have continuously or gradually variable heights and/or widths to form channels (53, 54) with different cross-sectional areas. Preferably, the honeycomb body is composed of two or more piles of metal plates (51, 52) whose extremities are imbricated. This honeycomb body (50) is preferably made of smooth metal plate (51) and of metal plates (52) having corrugations with different heights and widths in different areas. Honeycomb bodies having any distribution of channel cross-sections over the cross-sectional area can thus be produced, in particular bodies having smaller channels in the central area and larger channels in the outer area. Honeycomb bodies that receive flows in an irregular fashion can thus be better utilized, in particular as catalyzer bearing bodies in motor vehicle exhaust gas systems.
