Patent DE-4308467-A1 (DE)
Inventor: FUNKE HERBERT DR
IPC: F04B53/00
Filed: 1993-03-03
Abstract: In order to reduce the overall size of serial pump arrangements, several block-disk-like building elements are used. These building elements are made of a non-metallic material and lie against each other with their control surfaces in a (sandwich-like) stack (3). Two (4, 5) of these block-disk-like building elements (4, 5, 6, 7) have displacement chambers (25, 26) oriented transversely to the axis (27) of the stack, in each of which is guided a push piston (17, 18). Inflow and outflow bores (38, 42, 44) in which the high pressure mass flow, for example of a chemical buffer, is created, extend parallel to the stack axis (27). Both building elements (4, 5) form the two serially arranged pumping units of the serial pump arrangement and ensure a constant and continuous mass flow. Check valves (40, 41, 43) are provided at the suction and delivery side of both pumping units. Besides saving space, this arrangement ensures a highly constant and highly continuous mass flow, as the throughflow paths are as short as possible. The building elements may be made of metal-free but highly stable materials (in particular sapphire). Because of their shortness a minimal dead volume is obtained, and because of the metal-free materials there is practically no elasticity.

IPC: F01C1/344
Filed: 1994-03-08
Abstract: The motor has a casing (1) containing a hub (2), such that the hub rotates within the casing, or the casing rotates about the hub. This results from the action of a compressed medium flowing in chambers (13) between the curved surface (12) of the hub, and the inner surface (3) of the casing.

Patent DE-4408753-A1 (DE)
Title: Projection-lens unit
Inventor: KASIHARA TAKASI
IPC: G02B13/16
Filed: 1994-03-15
Abstract: The rise in temperature in an optical coupling liquid for cooling a front side of a cathode ray tube alters the refractive index of the liquid and alters the focusing distance of a projection objective, the result being that a picture projected onto a screen becomes blurred. The present invention relates to a countermeasure for compensating the defocusing on the projection screen. An optical coupling lens, which is one lens of the lens elements of the group of the projection objective, is designed for slight movement on the optical axis. The volume expansion caused by the rise in temperature in the optical coupling liquid is transformed into a pressure change. The pressure change is used for controlling the movement of the optical coupling lens. The focusing distance of the projection lens is automatically compensated relative to the rise in temperature in the optical coupling liquid.

Title: Determining time-dependent viscoelastic characteristics of liquid or fluid with solid component
Inventor: BURG ERIK VON DER DIPL PHYS
IPC: G01N11/16
Filed: 1994-06-06
Abstract: The viscoelastic characteristics determination method involves a glass-fibre body (1) with its parts deflectable by vibrations, entirely immersed into a substance (4). The frequency of a mechanical excitation using a piezoelectric element (2) is transmitted to the body (1), and the phase position of one of its periodically varying physical values is determined relative to that of the excitatory frequency. The time dependency of the mechanical vibration of the body or of a part of it, is determined across an ultrasonic objective (3). This produces an electrical signal, the phase position of which is relative to that of the mechanical excitation, and is used for determining the connection between the relative phase position and the excitation frequency.
