Title: Delivering cutting fluid in grinding operations - has velocity of cutting fluid leaving nozzle adjusted equal to peripheral speed of grinding wheel
Inventor: RUEBENSTRUNK DIRK
IPC: B24B55/02
Filed: 1991-08-10
Abstract: The method of delivering cutting fluid is applicable to a wide range of grinding operations where the fluid is pumped through a nozzle directed at the contact region between the grinding wheel and work. Specifically, the velocity of the fluid leaving the nozzle is adjusted to be equal to the peripheral speed of the grinding wheel. Turbulent flow is then replaced by a controlled laminar flow of the cutting fluid to the work surface. Adjustment of the cutting fluid velocity may be achieved by using a constant flow rate with a variable nozzle orifice, or by varying the flow rate through a constant nozzle orifice. USE/ADVANTAGE - Better grinding action. Incidence of burn marks and other surface defects is reduced

Title: Offset printing fluid - controlled by selective process to determine alcohol content
Inventor: BRAEUTIGAM WILFRIED
IPC: B41F7/32
Filed: 1991-12-31
Abstract: The appts. to establish and maintain the ratio of components in a fluid mixture uses a selective process to determine the alcohol content. The amount of wetting fluid required for offset printing is controlled during mixing and maintained in use. The alcohol is separated from the remainder of the fluid in an underpressure chamber (3) with an evaporation and overheating zone (A/B), and an electronically controlled heating system (4,4a). The dried alcohol vapour is measured (7) to give the alcohol content in vol%. The fluid is recirculated by an electronically controlled pump, and the fluid temp. is measured (8) where the alcohol content is dependent on temp. Removed alcohol is returned to the fluid by an ejector (6) to eliminate alcohol loss. The fluid pH is also measured at the temp. measurement stage (8). USE/ADVANTAGE - The mixture for offset printing is a mixture of water and alcohol at a given pH value and temp. The assembly gives a continuous monitoring and measurement which can be used by a computer to control the operation accordingly.

Patent DE-4224992-A1 (DE)
Inventor: ZERNICKEL ALEXANDER DIPL ING
IPC: F16C19/16
Filed: 1992-07-29
Abstract: In a zero-clearance radial ball bearing, two outer bearing race sections (4, 5) made by non-cutting methods together support an outer race (2) while between it and a concentric inner race (3) run bearing balls (1). Against the first bearing race section (4) bears a sleeve section (7) which circumferentially and axially surrounds the second race section (5). A spring component (10) pressing the two race section (4, 5) together acts between the sleeve section (7) and the second bearing race sections (5) in such a way that the balls (1) run with zero clearance. In order to improve the rigidity of such a radial ball bearing and especially the sleeve section (7), it is proposed that the two axial ends of the sleeve section (7) project axially beyond the balls (1). The sleeve section (7) is folded at its end away from its free end to form a radially internal cylindrical stiffening section (13) arranged concentrically with the sleeve section (7) which extends as far as the centre of the balls (1) and on which bears the first bearing race section (4).
