Patent DE-4116875-C1 (DE)
IPC: B23K26/08
Filed: 1991-05-23
Granted: 1992-09-24
Abstract: For slitting belt edges, a processing device which casts high-energy beams in turn onto one of two belts to be processed is used instead of a punching tool. The two belts are arranged in parallel next to each other and are transported alternately or in turn in the longitudinal direction in such a way that the belt edges to be provided with the slits are facing each other and, after cutting out one slit or shaping one edge contour of the slit of one belt, the high-energy beam passes over in a transverse direction to the next belt and begins there with the slitting or shaping of the edge contour of the slit. <IMAGE>

Title: Measuring tube for Coriolis mass flow meter - comprises carbon@ produced by pyrolysis of non-meltable plastics
IPC: G01F1/84
Filed: 1991-06-12
Granted: 1992-08-27
Abstract: A measuring tube (2) for a Coriolis mass flowmeter consists at least partially of carbon produced by pyrolysis of non-meltable plastics. The carbon may be carbon fibre-reinforced carbon or pref. vitreous carbon (e.g. formed by pyrolysis of phenolic resin). Usually, the tube is made completely of the carbon, but may consist of a support structure made of the carbon and provided with a lining and/or outer cladding. The wall thickness and/or the elasticity modulus may vary along the tube. USE/ADVANTAGE - The measuring tube is used in the measurement of mass flow (or density) of liqs., gases or mixt. subjected to Coriolis force. It is inexpensive, has extremely high fatigue resistance, constant oscillation properties and high bursting strength, has low surface energy and thus low pressure loss, has extremely low gas permeability and is easily joined to other components e.g. with an adhesive

Title: Monorail switch=point with blade deflection and rail connector
IPC: B65G9/00
Filed: 1994-08-03
Granted: 1995-12-21
Abstract: One of the switch-point blades (10,11) engages a locking device when travelled by the trolley and so completes a connection to the rail connector (7), the device designed so as to release the blade when freed from the trolley. The blades can be arrested in position by an iron flat switch (8) set above the connector (7) and forming a V or bow from the front whose side rims face upwards and whose centre (8c) lies above the connector. Vertical spacing webs (12,13) rising from the respective blades have their axes (12a,13a) at their upper ends to carry respective wheels (16,17) bearing on the iron switch (8). At the bottom point (8c) of the switch, the locking device forms a trough (8d) which is engaged by the web wheels (16,17) when their respective blades (10,11) come under trolley load. A spring (30) fitted between a fixed point and movable parts, e.g. blades (10,11) or webs (12,13) applies load to the engaged wheel so as to release this when its blade comes off load.
