Title: Opthalmological contact gel - can be used in virectomy to hold contact lenses in place, in three mirror contact glass investigations and in echography
Inventor: AWE MONIKA
IPC: A61K9/00
Filed: 1990-11-15
Abstract: A new ophthalmological contact gel is highly viscous, optically transparent and does not irritate the mucous membranes of the eye. USE/ADVANTAGE - The gel can be used in vitrecomy. The contact gel (2) is placed on the cornea (7) so that the contact lens (1) can be placed on top without damaging (e.g. scratching) the corneal epithelium. The contact lens is thus situated in labile equilibrium on the cornea, swimming in the contact gel. During operation the new gel inhibits the normally frequent slipping of the contact lens. The optical image formation inside the eye is not clouded with air or blood collecting under the contact lens. Unlike in previous cases. The gel can also be used with three mirror contact glass according to Goldmann and in echography, eliminating air between the ultrasound head and the eye which would alter the sound waves. Investigations do not need to be interrupted by topping up of the gel to replace gel which has flowed away.       In an example, powdered hydroxy propyl cellulose, e.g. Methocel E4M Premium was dissolved in 0.9% saline, filtered (e.g. over a G2 frit) to a concn. of 3%, filled (e.g. into plastic syringes) and finally sterilised.

Title: Vehicle engine spin-on-filter - comprises cellulose and/or glass fibre, wool, propylene], etc., bound with plastic to form pores converging in flow direction
Inventor: WEBER REINHARD
IPC: B01D35/31
Filed: 1990-11-16
Abstract: Spin-on-filters made of fibrous materials used in motor vehicles have to be exchanged complete with their housing when expired. Fibres used are microfibres which are bound together by plastic resin or welded together to form pores which converge in the direction of flow. A filter membrane is located on the exhaust side of the filter cartridge, on which the pores with the smallest dia. are found. The pores between the microfibres are at their smallest at minimum distance from the central axis. The microfibres are made of chopped cellulose and/or: glass fibre, wool, acrylic fibre, visco fibre, polypropylene, polyethylene and are impregnated with methyl silicone. USE/ADVANTAGE - When a filter cartridge is exchanged, it is unnecessary to exchange a filter housing and that there is thus no disposal problem (claimed).

IPC: F16H9/06
Filed: 1990-11-29
Abstract: The multi-stepped belt gear (1), particular a V-belt gear has at least two adjoining pairs of belt discs (7a, 7b, 7c) which can rotate about parallel rotary axes (3, 5). A belt (6, 6b, 6c) is associated with each pair (7a, 7b, 7c) of discs so that in the unstressed state the belts slip through easily.

The tension roller is preferably set on a sliding sleeve (14) which can be moved on the axis (13) and locked in each displaced position. USE/ADVANTAGE - It is no longer necessary to change the belt on the floor polisher when changing the gear since the transmission function of the desired belt is produced through the axial adjustment of the tension roller.

Patent DE-4100743-A1 (DE)
Inventor: STEPHAN WOLFGANG
IPC: B01F5/10
Filed: 1991-01-12
Abstract: The invention relates to a metering device for liquid, paste or powdered additives for treating a fluid in a bath with a metering pump connected to an additive reservoir and a line with a second pump via which some of the fluid to be treated can be extracted from the bath and returned to the fluid in the bath, the outlet of the metering pump being connected to this line. To allow the metering pump to be more closely adjusted to variable metering areas, i.e. surfaces of fluids to be treated, especially in large plants, e.g. waste water plants, tanks and processing baths, it is proposed that the inlet of the second pump be also connected to an additive fluid via a valve, and that the valve be controlled by a sensor detecting the level of the fluid to be treated and that all the components of the metering device be assembled on a movable carriage.

Patent DE-4102400-A1 (DE)
Inventor: KOSIKOWSKI THOMAS DIPL ING
IPC: C25D21/10
Filed: 1991-01-28
Abstract: The invention relates, first of all, to a process for the treatment of plate-like articles, in particular relatively thin printed circuit boards (5) with through holes (6), in electroplating plants or similar plants, in which a to-and-fro movement (7) is imparted to the articles in the treatment liquid (20') and air which flows upwards on both sides of the articles is injected into the treatment liquid. In order to prevent the adverse effects observed in the state of the art and due to the emergence of the injected air into the treatment liquid, on the electroplating result achieved and also the resultant harmful mechanical effects on the articles to be treated, in particular thin printed circuit boards, the air outlet flow (36) into the treatment liquid (20') is moved to and fro (7') synchronously with, and in the same direction as, the product movement (7). The result is achieved that the air flow moving (7') synchronously with the product movement (7) allows air rising upwards through the treatment liquid continuously to flow over the articles on both sides during the entire product movement. The invention furthermore relates to an apparatus for carrying out the method. <IMAGE>

Patent DE-4110494-A1 (DE)
Inventor: KUHN WIELAND ING GRAD
IPC: B60T8/175
Filed: 1991-03-30
Abstract: A hydraulic braking system with anti-lock and drive slip control has an electric-motor-driven hydraulic pump (6, motor 7) to provide auxiliary pressure during controlled braking and during drive slip control by brake engagement. During a drive slip control process, the speed of the hydraulic pump (6) is reduced by limiting the power absorbed by the drive motor (7) of this pump to a predetermined value at which the speed and noise developed is low in relation to these values. In critical safety situations or with certain malfunctions of the control, the power limitation is rendered inoperative. The power is limited with the aid of relays (A, B) and an ohmic series resistor (RV) or a semiconductor relay or electronic relay (10').
