Title: Surgical instrument for removing cataract from eye - has circular blade which is rotated by drive in handle
Inventor: SASU MICHAEL DR MED
IPC: A61F9/007
Filed: 1990-04-23
Abstract: A surgical instrument for operating on a cataract of the eye has a hollow handle (1) which receives the blade holder (4). The blade is made from a flat strip of flexible material which is bent to form a ring (5).

Title: Measuring speed of flow by ultrasonic echo signals - using defined time window in reflex method for base and surface echoes for correlative evaluation
Inventor: GOHLA BERNWARD DIPL ING
IPC: G01P5/18
Filed: 1990-08-27
Abstract: The time window is defined within the base and surface echoes. A further echo originating from an intermediate vol. cell is evaluated. The max. ultrasonic-pulse-sequence time is shorter than the calculation time for digitising, filtering and integration. The signals received from two spaced ultrasonic sensors are evaluated and/or compared several times. Two sensors (16a,16b), each with a transmitter and receiver, are placed over the flowing medium (12), e.g. in a manhole shaft (14) of a canal system. Each sensor is connected to an evaluating computer (32). The speed of a vol. cell (26) can be evaluated by the provision of a time window between the echoes received from the base (28) of the contg. pipe (10) and the surface (24) of the fluid. USE/ADVANTAGE - As well as measuring the speed of flow can also derive other information such as if the flow is laminar or turbulent, if the vol. cells maintain a constant distance w.r.t. the base or surface, if there are deposits on the base or surface.

Title: Anodic bonding of insulating and conductive discs to sandwich - involves using two hot plates for heating and applying pressure to minimise distortion and allow more than two discs to be bonded
IPC: H01L21/20
Filed: 1991-10-30
Abstract: In anodic bonding of an insulating disc to a conductive disc, the discs are sandwiched and heated under pressure on a hot plate and an electrical potential is applied to the sandwich. The novelty is that another hot plate is used for heating and applying pressure. The hot plates consist of stainless steel, pref. coated with a metal resistant to bases. A second insulating disc is used, with the conductive disc sandwiched between the two insulating discs, and the polarity of the potential applied to the hot plates is reversed once during bonding and/or the potential is applied to the insulating disc and one of the hot plates. Additional conductive disc(s) may be pressed onto the outside of the insulating disc(s). USE/ADVANTAGE - Useful for bonding discs of metal or semiconductor, e.g., Si, Ge, GaAs, InP or SiGe wafers, to insulating discs, e.g., of glass. Use of the second hot plate minimises distortion and makes it possible to bond more than 2 discs.
