Title: Solenoid valve for a hydraulic brake system with slip control
Inventor: BECK ERHARD
IPC: B60T8/50
Filed: 1988-10-01
Abstract: A solenoid valve for a hydraulic brake system with slip control is proposed, essentially comprising a valve seat receiving a valve tappet, a housing frame surrounding a valve housing (12), two pressure medium lines (1, 2) passing through the valve housing (12), and a solenoid arranged in the housing frame. For advantageous flow control of the solenoid valve with different pressure gradients as a function of the direction of flow the invention proposes that in the valve housing (12) a non-return valve (4), formed from an orifice plate (3) and movable valve body, be connected to two pressure medium passages (1, 2), so that during the pressure build-up phase of slip-controlled braking, the fluid flows through the orifice plate (3) restricted with a small pressure gradient and on initiation of the pressure reduction phase in the opposite direction of flow, the valve body on lifting off from the valve seat exposes an extensive annular gap for the generation of a large pressure gradient. <IMAGE>

Patent DE-3841626-A1 (DE)
Inventor: ARNOLD RUDOLF
IPC: A01D34/64
Filed: 1988-12-10
Abstract: In a mowing apparatus for three-point linkage, a strut (13) of variable length is inserted between a supporting frame (1) and an intermediate carrier (2). Its function is to limit the vertical movability of the intermediate carrier (2) in the upward and downward direction and, with the support frame (1) in the raised position, to form together with the supporting frame (1) and intermediate carrier (2) an articulated triangle which absorbs the vertical load arising from the inertia force of the inner part of the mowing bar (4) whilst the load rising from the inertia force of the outer part of the mowing bar (4) is transmitted in a strictly defined manner to the supporting frame (1) by means of a tension connection (9, 10). The effect of the strut (13) also prevents a buckling of the rotary axle (3) between the intermediate carrier (2) and mowing bar (4). <IMAGE>

Title: Farrowing station with pneumatic/electronic control means
Inventor: HANSELMANN GUENTER
IPC: A01K1/02
Filed: 1988-12-19
Abstract: The inventor has provided a farrowing station which virtually completely satisfies the requirements of the animals (sow and piglets). Over a period from shortly before the birth to approximately 10 days thereafter, the sow is situated in this farrowing station with her piglets. Subsequently, they are shut into a conventional farrowing pen. The farrowing station comprises a concreted standing surface for the sow. Fitted to the left and to the right of this standing surface is in each case one movable, fully perforated platform, the frame of which consists of iron sections. These platforms serve as fully air-conditioned nests for piglets and, depending on whether the sow is standing or lying down, are moved upwards or downwards with the aid of wire cables, deflection rollers and a suitable hoist. A corresponding sensor records whether the sow is lying down or standing and then correspondingly sets the hoist in motion via a switch box which is designed specifically for this purpose. By virtue of this design and technology, the piglets are protected to the greatest extent from being crushed and trampled by the sow.

Inventor: MARGARIS PANAJOTIS DIPL ING
IPC: H04L12/26
Filed: 1989-03-21
Abstract: The invention relates to a method for investigating a digital data stream in which the data stream is subdivided into subunits (Io...In) and a subunit (Ii) is in each case examined within one method cycle (Ti), the subunit (Ii) being subjected to a comparison with a reference value (Si) in a first part-step (MS0). To provide a great degree of freedom with respect to the investigation criteria and the logical combination of the investigation results of the respective subunits, the invention provides that in a further part-step (MS1), an output information (MEi) is formed by user commands (X0, X1, X2) by interrogating the comparison result with respect to a selectable questioning or, on the one hand, the output information (MEi-1) of the preceding method cycle (Ti-1) is taken over and, on the other hand, is obtained as output information (MEi+1 ...) for subsequent method cycles (Ti+1 ...) (preliminary hold decision). A preliminary hold decision can also be made in an additional part-step (MS2) as a function of other method variables. In a supplementary part-step (MS3), the output information (MEi) can be weighted further by further user commands (X4, X5, X6) as a function of the output information (MEi), in such a manner that the preliminary hold decision is cancelled, remains in existence or the output information (MEi) is obtained for all subsequent method cycles (Ti+1 ...Tn) (final hold decision). <IMAGE>
