Patent DE-4307855-A1 (DE)
Title: Bypass arrangement, especially for an antilock device
Inventor: FRIND ADOLF DIPL ING
IPC: B60T8/42
Filed: 1993-03-12
Abstract: The invention relates to a bypass arrangement for a brake system, which has applications primarily in motor vehicles. It serves to periodically reduce the brake pressure present in the wheel brake cylinders of the wheels with the aim of preventing or interrupting possible locking of the wheels and of quickly restoring the braking action initiated by the driver. The invention proceeds from the fact that, during the braking action, any of the wheels can lose sufficient road grip due to a wide variety of external influences or ones inherent in the vehicle and that without this the directional action, especially of the steered wheels, is lost. Any sensing of the individual wheels is on principle dispensed with because, from a minimum brake pressure, which is adjustable, prompt relieving of the brake by the driver appears to be the correct preventive measure due to the various external effects. In the known devices costly and complex sensing, control and separate drive devices are used, resulting in relatively high costs, these devices then generally being offered only as optional equipment. The bypass arrangement and hence the drive are generally actuated by means of a pressure relief switch once a preadjustable initial pressure in one of the brake lines of the brake circuits is exceeded. The brake pressure is ... Original abstract incomplete. <IMAGE>

Title: System for communication via satellites
Inventor: KONRAD MICHAEL DIPL ING
IPC: H04B7/185
Filed: 1993-03-16
Abstract: The described system for communication via satellites (2) contains at least one transmitting station (1), at least one receiving station (3, 4) and at least one monitoring circuit (B1, B3, B4) to monitor the signal (s) transmitted by a transmitting station (1) via the satellite path and received by a receiving station (3, 4). If this signal (s) is affected by interference, a low-cost alternative path is created by providing at least one network module (C1, C3, C4),   - which automatically sets up a communications link between a transmitting station (1) and a receiving station (3, 4) via a switched network (5) when a parameter of the signal (s) assumes critical values, and - which clears down this link when the parameter of the signal (s) assumes uncritical values.   <IMAGE>

Title: Flap-type shut-off valve
Inventor: SCHULER HEINRICH DIPL ING
IPC: F16K1/226
Filed: 1993-04-02
Abstract: The invention relates to a flap-type shut-off valve. The sealing edge formed on the periphery of a flap interacts with a sealing seat on the inner circumference at the end of a pipe stub. The wall thickness and length of the pipe stub, which is held rigid at the other end, are dimensioned in such a way that its radial elasticity permits a sufficient radial flexibility at the sealing seat to make possible self-centring and hugging of the flap in the event of temperature-related deformations or tolerances. <IMAGE>

Title: Collision prevention system for vehicles - uses distance sensing arrangement with ultrasound transmitter mounted on front face of vehicle.
Inventor: LAUKIEN WERNER
IPC: G01S15/931
Filed: 1993-04-17
Abstract: The vehicle safety system includes a distance sensor, for determining distance to a vehicle travelling ahead, and a program-controlled computer (1). The distance sensor includes an ultrasound transmitter (2) mounted on the front face of the vehicle and functioning at a frequency above 20 kHz, above the audible frequency range. The sensor functions according to an echo-time principle, whereby the ultrasound waves when confronted with an obstacle, are reflected back off the obstacle and reach the distance sensor after a time delay proportional to the obstacle's distance i.e. the vehicle travelling ahead. The computer differentiates the sensors reading over time and activates a warning device (5) or brakes the vehicle if a collision is otherwise unavoidable. The sensor detects objects within a 30 deg. beam angle. ADVANTAGE - Reliably and safely avoids motoring incidents without incurring high cost of radar based systems.

Title: Drilling machine for three-point attachment on tractors - has funnel-shaped seed hopper moving from raised operating position near tractor to lowered filling position near seed share
Inventor: RAUCH NORBERT DIPL ING
IPC: A01C15/00
Filed: 1993-05-08
Abstract: The seed hopper (17) is mounted on share rail (50) and is moved parallel to same back to filling position when share rail is stationary. Hopper is loosely supported on support frame at least in operating position and by means of movable links (35).

This keeps masses being moved to minimum. USE/ADVANTAGE - CG is near tractor when hopper is in operating position but near ground for filling and emptying. Inspection of dosing elements is also easier.

Patent DE-4332744-A1 (DE)
Title: Method for casting shaped parts
Inventor: HOLDSCHICK HARALD
IPC: B22D19/02
Filed: 1993-09-25
Abstract: The invention relates to a method for the production of shaped parts, a metal or a metal alloy being introduced into a prepared casting mould. The intention is to develop the method in such a way that, while permitting simple production, it also permits effective armouring by means of the shaped part. The proposal is that inserts of different hardness and/or toughness should be locked in place in the mould cavity and that the metal or metal alloy should then be poured into the said cavity, the inserts being encapsulated by the metal to give a composite material of maximum resistance to violent destruction. <IMAGE>

Title: Fastening coupling for corrugated pipes (tubes)
Inventor: RUMPEL JUERGEN
IPC: F16L25/00
Filed: 1994-03-22
Abstract: A fastening coupling for corrugated pipes comprises a tubular sleeve (1) and a securing tongue (15) which is arranged in a cutout (13) in the circumferential wall of the sleeve and is connected integrally to the sleeve via two lateral torsionally elastic webs (17). The securing tongue (15) is designed as a two-armed lever. One lever arm (15a) bears a locking protrusion (19) for engagement into a circumferential groove of the corrugated pipe (21), and the other arm (15b) serves as a pressure plate for pivoting the securing tongue into the release position. Each of the torsionally elastic webs (17) is of such a length that it is flexurally elastic in the axial direction of the sleeve, with the result that the securing tongue (15) can be displaced in the axial direction in the cutout (13) and comes into contact with bevelled guide surfaces (27, 39) of the sleeve. The guide surfaces (27, 39) are configured such that, in the event of tension on the coupled corrugated pipe (21), the locking protrusion (19) is pushed more firmly inwards into the groove of the corrugated pipe and/or that, when the corrugated pipe is pushed in, the locking protrusion (19) is pivoted outwards into the release position. <IMAGE>

IPC: H01F7/16
Filed: 1994-05-10
Abstract: The magnet system has a cylindrical armature movable along an axis (A). An exciting coil (1) is arranged coaxial to the armature (5). A magnet iron system (3) for guiding the magnetic field has a hollow cylindrical guide tube (3a) coaxial to the axis (A) and between the armature (5) and the coil (1). An armature counter-piece (3b) faces the tube (3a) at a given distance from it. This has a back wall (6) facing the armature (5) and a hollow cylindrical wall end or control cone (10). The latter lies between the armature (5) and the coil (1) in the direction of the armature (5). A housing wall (3c) is arranged around the coil (1) and connects the counter-piece (3b) and the guide tube (3a). When current is applied to the coil (1), a closed magnetic field line is generated in the magnet iron system (3). The magnet system with its guide tube (3a), counter-piece (3b) and housing wall (3c) has a point which reverses the magnetic field lines (2) where the deflection angle of the field lines is adjusted or changed. At this point. the system (3) has a cross-section which is increased with respect to the armature cross-section (Q1) so as to reduce the magnetic flux density at that point.
