The inner pipe contains a hydraulic feed which drives an outer drive wheel which in turn operates a series of propellers mounted in the rudder body. The outer pipe serves as the hydraulic return. Vessel control is obtained by rotating the shaft and thus the propeller. USE/ADVANTAGE - With hydraulic power source, location of power and pack and propeller not interdependent.
Patent DE-4114163-A1 (DE)
Inventor: WITZ GUENTER
IPC: B65D81/02
Filed: 1991-04-30
Abstract: The box-like package made of a thermoformable plastics sheet being of a one-piece, punched blank provided with folding scores. Supporting profiles are molded out inwardly or outwardly from individual regions of the blank by means of thermoforming. These supporting profiles resiliently support the packed product which is susceptible to shock; they are therefore preferably adapted to the contours of the product. The entire pack, including the supporting profiles, forms a single part, so that additional supporting inserts are superfluous. The most important advantages: saving in packaging material, dispensing with troublesome to handle additional inserts, good stackability of the sheets before assembly, readily recyclable monomaterial package.

Title: Spinning spindle - has discontinuous section formed in casing for damping vibration between base bearing and housing base
Inventor: BRAXMEIER HANS
IPC: D01H7/10
Filed: 1991-07-03
Abstract: A spinning spindle is held in two bearings in a casing inside a housing which is fastened to the spindle rail. As a means of damping the vibration between the base bearing and the housing base, a discontinuous section is formed in the casing, and the space between the casing and housing is filled with a damping medium to reduce the sound velocity.

Title: Glass panel fixing
Inventor: SCHERZL HANS
IPC: F16B5/02
Filed: 1991-09-17
Abstract: Glass panel fixing consists of a bracket (10) which is attached to the glass panel (1) by a bush (9) fitting against the surface of a hole (2) through the glass, and a cylindrical insert (4) which goes inside the bush. The insert has a flange (5) at one end and a threaded hole (6) through the middle to receive two bolts (8). The bush is compressed by the flange and a washer (7) beneath the bolt head at the other end. The flange and washer are of smaller diam. than the hole through the glass and cause the bush to squeeze outwards and lock inside the hole when the bolts are tightened. In variants of the design the bush, flange and washer can be located entirely inside the hole through the glass panel, or the bush can be expanded by a conical expansion bolt. The bush can be made from a polyamide, e.g. reinforced with glass fibres.

Title: Hydraulic valve stem damper - has hydraulic chamber to which oil is fed under orifice control during early phased of valve opening
Inventor: KRUEGER HERMANN PROF DR
IPC: F01L9/14
Filed: 1992-01-30
Abstract: A hydraulic damper for a valve stem (1) has a hydraulic fluid filled chamber (25), which has a flow connection (16) and orifice control (20,27) when the valve is closed and in the first phases of opening. In the first phases of the valve opening, the damper chamber enlarges and thereby takes up a greater oil volume. This ensures an independent adjustment of the damper to changes around the valve and valve seat (6), and the damper prohibits any influence on the valve curve due to changes in valve geometry. ADVANTAGE - Provides for geometry changes around valve.
Patent DE-4204401-A1 (DE)
Inventor: BULLMER WOLFGANG DIPL ING
IPC: F16H61/04
Filed: 1992-02-14
Abstract: The proposal is for a device for controlling the output torque (Mab) of an automatic gearbox (10) during a gear changing process in a motor-driven vehicle at a value preset by the driver, in which the gearbox (10) has at least two gear ratios (11, 12) alternatively engageable via clutches (16, 17). When changing up, the clutch (17) allocated to the higher ratio is first continuously engaged in a time-controlled manner, at the same time the engine torque being correspondingly increased to keep the output torque (Mab) constant. When the first clutch (16) allocated to the lower ratio no longer transmits any torque, it is disengaged. Thereupon the second clutch (17) is taken to its synchronous rotation speed by reducing the engine torque (Mm) and driven further with no slip. Changing down takes place in the reverse order. In such changing processes, greater changing convenience is achieved without any jerking.
Patent DE-4205103-A1 (DE)
Title: Spinning frame - has profiled funnel to control the airstream at the entrance to the output roller pair of the drafting zone
Inventor: RUMPEL HORST
IPC: D01H5/72
Filed: 1992-02-20
Abstract: The output roller pair in the drafting zone of a spinning frame is accompanied by a funnel which covers the entrance to the nip of the rollers. This funnel controls the airstream in rapidly revolving rollers, as it has profiled grooves to prevent turbulence at the nip. Pref. the drafting zone has a funnel entrance for the roving which is gripped by the double apron revolving on the rollers and tensor bars. On account of the faster revolution of the output roller pair, the roving is tensioned and drawn out at the entrance. The funnel is formed to cover the nip of the rollers. The funnel is grooved with profiles running parallel to the flutes across the output roller. The profile adopted may be triangular, beaded, elipse, semi-circular, trapezium, according to the amount of action required. The lines of the grooves may follow an arrow head formation, pointing up in the top section and down in the bottom section. The arrow head may curve to a cusp, to direct the airflow away from the central point at the nip of the output rollers. The funnel may also be adjusted to a suitable position in front of the rollers to achieve the most efficient performance. Similarly the depth of the grooves which form the profile on the funnel face may be cut to the depth required. ADVANTAGE - The airstream is prevented from concentrating on the yarn, to extract fibre, causing thin places and fluff, or leaving hairy yarn.

Inventor: BOEHM KARL-HEINZ
IPC: F24C14/02
Filed: 1992-05-13
Abstract: The roasting oven, especially with a pyrolytic self-cleaning system, has an outer pane (13) which can move in relation to the inner pane (12), when the door (11) is closed. Pref. the outer pane (13) is moved into a position away from the inner pane (12) according to a selected heating function and/or the temp. at the muffle (2) with a mechanical or electro-mechanical or thermo-mechanical movement action. The outer pane (13) is moved parallel to the inner pane (12), to a given gap from it, or the outer pane (13) is swung by a given angle when the temp. exceeds 300 deg.C or a pyrolytic self-cleaning program has been selected. The heating control (7) allows the muffle temp. to exceed a set threshold value only when the outer pane (13) is in the open position. A microswitch at the door (11) registers the setting of the outer pane (13). USE/ADVANTAGE - The system is for an oven with a self-cleaning system, where temps. of 500 deg.C can be experienced. It gives a cooling action for the outer pane of the oven door, without any interruption at the viewing window zone.

Patent DE-4224007-A1 (DE)
Inventor: BECK ERHARD DIPL ING
IPC: B60T8/26
Filed: 1992-07-21
Abstract: Following a general trend, the present invention proposes an anti-lock hydraulic braking system in which a braking force regulator has also been included. Unlike the prior art systems, the braking force regulator (21) used here, however, is blocked only when the pump (18) builds up pressure. This means that the braking force regulator (21) exerts its pressure reducing function at every uncritical brake application as soon as its changeover pressure is reached. This provides the advantage over other braking regulators which are actuated only when the anti-lock fails that the seizing or clamping of functional components of the regulator is prevented and slip control will be needed on fewer occasions.
