Title: Hydrostatic power steering device
Inventor: FASSBENDER ROLF
IPC: B62D5/097
Filed: 1989-01-14
Abstract: Hydrostatic power steering devices transmit the steering force to the steered wheels via oil columns enclosed in lines. Such steering systems consist essentially of a metering pump (5) and a steering valve (2) which are combined to form one constructional unit. Via a steering valve (2), the metering pump (5) distributes to a steering motor (8) in accordance with the rotational movement at a steering wheel the stream of oil produced by a servo pump (1). The stream of oil synchronises the rotational angle at the steering wheel with the locking angle of the steered wheels. Hydrostatic steering systems tend to experience pressure vibrations. According to the invention, these pressure vibrations are reduced whilst avoiding excessively high pressure losses. In a feed line (4) to the steering system, a damping valve (11) is provided whose damping piston (12) shuts off, in a central position which is centred by springs (13, 14), a branch line (6) which branches off to the metering pump (5). When pressure control occurs by means of a rotational movement at the steering wheel, the damping piston (12) opens a flow cross-section from the feed line (4) to the branch line (6) leading to the metering pump (5). By means of this measure, rapid pressure changes in the feed line (4) when there is a drawing off of flow at the metering pump (5) only affect the branch line (6) in a delayed fashion (Fig. 3). <IMAGE>

Title: Pressure resistant sound wave reflectors for underwater sonar systems - made from an expanded elastic material and blowing agent gas having larger molecular dia. than the elastic material
Inventor: ARENS EGIDIUS DIPL ING
IPC: G10K11/20
Filed: 1989-03-04
Abstract: Pressure resistant reflector is made from a foamable elastic material and a gas having a larger mol. dia. than the material as blowing agent. A pref. system comprises foam rubber as the elastic material and SF6 as blowing agent. USE/ADVANTAGE - The material is highly resistant to pressure since the blowing agent gas cannot diffuse out of the material, and the reflectors can therefore be used at different depths without any change in sound reflecting properties

Inventor: VOGELSANG HORST
IPC: H02G9/06
Filed: 1989-03-24
Abstract: A cable conduit bundle comprising a plurality of plastic ducts which have a polygonal external cross-section with more than three corners, especially a cable conduit bundle for laying directly in the ground. The individual plastic ducts supplement one another in a complementary manner. The plastic ducts are linearly combined by means of integrally formed deformable connecting webs and hence can be separated from the bundle to form a flat duct set.

Title: Mfr. of wooden articles - has surface working tools, carving round wood into intermediate product
Inventor: GRIMME GUENTER
IPC: B27B1/00
Filed: 1989-05-02
Abstract: A method of manufacturing wood products from roundwood which is to be subdivided into at least two wood products has a production line incorporating profiling chippers and saws.

Patent DE-3918409-A1 (DE)
Inventor: SCHLEUPEN RICHARD DIPL ING
IPC: F02P7/067
Filed: 1989-06-06
Abstract: A device for controlling an internal combustion engine in a motor vehicle is described which comprises a sensor system with a transmitter disc (10) surrounding a shaft of the engine, opposite which is a fixed receiver (20). Around the periphery of the transmitter disc are segments (11, 12) whose number is proportional to the number of cylinders. A permanent magnet (15) is allocated to at least one of the segments (11, 12) as a marker. The signals generated by the segments (11, 12) or the permanent magnet (15) in the receiver (20) are sent to a control circuit (21) for the ignition, injection and the like of the vehicle which comprises several threshold switches, the thresholds of which are adjusted depending on the amplitude of the signal provided by the receiver (20). Matching the switching thresholds to the various amplitudes of the output signals from the receiver (20) prevents self-adjustment and hence facilitates, for instance, the highly accurate allocation of the ignition pulses in a distributor-less high voltage allocation system with a single transmitter.

Inventor: EPPERT GUENTER DR
IPC: B01J20/32
Filed: 1989-09-02
Abstract: In prepn. of an organically modified SiO2 gel by reaction with alkyl- or aryl-alkoxy silanes, the SiO2 gel is heated to 200-360 deg. C with an excess of the liq. silane covering the whole gel, then percolated under pressure with wash liqs., and finally dried with passage of inert gas.

Patent DE-3930588-A1 (DE)
Title: Thread snips
Inventor: VOGEL DAVID S
IPC: B26B13/12
Filed: 1989-09-13
Abstract: The thread snips includes two metal blades connected together, adjacent their rounded, ear ends, so that their pointed, front ends may be moved or pivoted relative to each other, in planes parallel with the planes of the metal blades, between open and closed positions. The rearward portion of each metal blade has a reduced thickness. Plastic inserts are moulded onto these rearward, reduced thickness portions so that the inner facing side surfaces of the plastic inserts define a smooth continuation of the inner facing side surfaces of the metal blades. The rearward ends of the plastic inserts are thicker than their forward ends. The increased thicknesses force the rear ends of the metal blade apart, and thus cause the blades, forward of the point of connection, to bend or arch.

Title: Crane hook gear with safety lock - has hydraulic damping cylinder to control delay time for operation of hook release bolt
Inventor: HOLSTE DIETER
IPC: B66C1/38
Filed: 1989-11-16
Abstract: The crane hook gear has a cylindrical housing (8) with the hook (9) at the lower end and a hydraulic clamping cylinder (14,15) a the upper end. The hoisting load is transmitted to the hook through the main rod (7), cylindrical housing and cross-pin (10). During lifting, the hook is held in the lifting position by engagement of the locking bolt (13) in a recess (11) of the hook. When the load is set down the clamping cylinder allows the main rod (7) and attached link (32) to descend at a controlled rate until the link is at its bottom position in the recycling cam track (36,37), when the hook can be released to swing clear.  The hook is automatically released by momentarily taking up the load and hence lifting the locking bolt (13) against the spring (12). The time elapsing between setting down the load and releasing the hook can be varied by adjustment of the throttle valve (25). USE/ADVANTAGE - Simple, robust design. Delay time can be adjusted to suit conditions and is unaffected by the way load is handled.  Does not require external power lines.

Title: Preparing domestic fuel briquettes - by mixing fine dust or waxy starch with non-caking crude coal, esp. anthracite
Inventor: SCHLUETTER ALOYS
IPC: C10L5/28
Filed: 1989-12-05
Abstract: Domestic briquettes (I) are produced from non-caking crude coal, esp. anthracite, and starch. The novelty is that the starting coal has a grain size of 0.3 mm, to which is mixed fine dust (3-5 wt.%) with a grain size of not more than 100 microns, and 2-10 wt.% waxy maize starch. The briquettes obtd. are maintained at 300-400 deg.C until at least a 3 mm thick shell on the briquette is formed, in which the starch is denatured. By mixing 3-5 wt.% starch into the starting coal, moisture is pref. kept at 6-8%. After heat treatment the briquettes have a waxy layer. ADVANTAGE - By using liq. starch the moisture content is reduced. The starting solidity of the briquettes is sufficient for the briquettes to transport heat supply, in which the moisture of the briquette is slowly driven out. At the same time the solidity increases.
