IPC: C11D3/382
Filed: 1990-12-24
Abstract: In the production of enzyme granulates with grain sizes from 0.1 to 2 mm, containing 2 to 20 % wt. proteases, lipases, amylases and/or cellulases, 10 to 50 % wt. swellable starch, 5 to 50 % wt. granulating agent, 3 to 12 % wt. water and not more than 10 % wt. water-soluble salt, by extruding an enzyme pre-mixture obtained by mixing a fermentation liquor cleared of insoluble components and concentrated with additives and spheroidizing the extrudate in a rounder, the use of relatively highly concentrated fermentation liquours has previously been necessary. By removing the insoluble components from the fermentation liquor by micro-filtration and mixing with additives which, in relation to the finished granulate, contains 10 to 35 % wt. cereal flour, it is possible, by the use of low-concentration fermentation liquors, to obtain highly active enzyme granulates with a long shelf life which are suitable for inclusion in washing and cleansing agents and are distinguished by uniform solubility properties in aqueous washing and cleansing baths.

Patent DE-4124465-A1 (DE)
Inventor: MEZGER MANFRED DIPL ING
IPC: G01M3/32
Filed: 1991-07-24
Abstract: The fuel-tank aeration system proposed comprises the following elements: a tank (10); an adsorption filter (13) which is connected to the tank via a connection line (12) and which has a vent line (14) that can be closed off by a shut-off valve (15); a tank aeration valve (16) connected to the adsorption filter via a valve line; a pressure feed-in point (21) on the valve line near the aeration valve and a tank-mounted pressure sensor (11). The aeration system can be operated in the following way: the aeration valve and the shut-off valve are closed; compressed air is fed to the pressure feed-in point; the pressure in the tank is measured and a check is made as to whether the pressure satisfies a pre-determined criterion, and the system deemed to be non-operable if this is not the case. The operability of the system proposed can be checked very reliably using the method described since it is possible to apply, without any risk of damaging the system, test pressures which are significantly higher than those which would normally occur in a tank aeration system without the externally applied pressure.

Inventor: ROTHHAMMER REED
IPC: B63C9/135
Filed: 1992-04-15
Abstract: A water exercise device to be worn by a person who is desirous of acquiring increased buoyancy while exercising in water. The device includes a waist-encircling band 11 of flexible buoyant material, such as elastomeric foam, through which is intertwined a flexible and inextensible belt 15 to be strapped around the user's waist. The buoyant band 11 extends circumferentially behind the wearer from just forward of each hip where it terminates in an enlarged lobe portion 12. Thus the stomach and general body area in front of the wearer are free from interference and the buoyancy of the two lobe portions and interconnecting back band tend to raise the wearer to a vertical position as opposed to a naturally occurring forward face to the water position. <IMAGE>

Patent DE-4223466-A1 (DE)
Inventor: KIM SEOK-BIN
IPC: H01L27/02
Filed: 1992-07-16
Abstract: A semiconductor device employs an NMOS transistor 9, 11, 45 connected between a voltage source line 5. Vcc and ground voltage line 7, Vss in parallel with an internal circuit 41 so as to discharge any electrostatic voltage through the NMOS transistor to ground. The NMOS transistor 45 is designed to perform breakdown operation at a lower voltage than that of a transistor of the internal circuit 41, so that when the voltage of the voltage source line Vcc is increased by the voltage of the electrostatic voltage, the NMOS transistor works first. A diffusion region 9 forms the drain and source of the NMOS transistor and a polysilicon line 11 forms the gate. In another arrangement, the source and drain diffusions are separated and pairs of contacts are applied to each region. <IMAGE>

Title: Link connection between two articulated vehicles
IPC: B60D5/00
Filed: 1992-09-18
Abstract: The two rotary rings (5) of the rotary ring link (4) make possible bending movements between the two vehicles, and elastic parts, pref. rubber components (11), facilitate further movements between them. The one of the two rotary rings is rigidly connected to its corresp. vehicle, while the other is connected to its vehicle via the elastic parts.Forces directed in the vehicle longitudinal direction (3), i.e braking and drive forces, are transmitted between the two vehicles (1, 2) via pressure and tractive activation of the elastic parts, which under the influence of pressure forces are relatively slightly deformable. Bending movements between both vehicles around an axis (9) horizontal in the vehicle cross direction lead to tractive and pressure deformations of elastically deformable components.
