Patent DE-3824789-A1 (DE)
Title: Wheel axle for vehicles
Inventor: MAYER KARL MATTHIAS
IPC: B60G11/04
Filed: 1988-07-21
Abstract: In a known vehicle wheel axle an oscillating link running parallel to the vehicle longitudinal axis supports two transverse links, the ends of which each support, in pairs, a wheel axle plate, the transverse links forming a parallelogram with the wheel axle plates. In the area of the support for the transverse links a spring is provided between the oscillating link and the vehicle frame, which leads to the disadvantage that the said spring has to transmit the entire load between vehicle frame and the wheels. In order to reduce the load to be transmitted by the spring, the spring is designed as a flat spring (5), which runs as an extension of the oscillating link (3) and forms a continuous beam with this, and the transverse links (8, 9) are articulated approximately in the middle of the said beam. <IMAGE>

Title: Electrical switch, especially for motor vehicles
Inventor: HOFMANN GEORG
IPC: H01H13/60
Filed: 1988-08-27
Abstract: The invention relates to an electrical switch which has a housing, a switching rocker (which is mounted within the housing such that it can rotate and can pivot to and fro between two limit positions) and a snap-action spring which is constructed as a leaf spring on which the switching rocker engages, is clamped in between two supporting bearings and interacts with a first stationary contact and at least one second stationary contact. Since the snap-action spring is supported on the first stationary contact at both ends and the switching rocker is fastened to the snap-action spring and is supported via it such that it can rotate, a reduced current flow on the snap-action spring and a longer switch life can be achieved.

Title: Merchandise carrier
Inventor: OCZKOWSKI BRUNO VON
IPC: A47F5/08
Filed: 1988-10-12
Abstract: The invention relates to a merchandise carrier for detachable fixture to a display wall of a self-service shop or the like, consisting of a holder which is to be fixed to the display wall and of a rod which projects freely on the outside of the holder and carries the merchandise to be displayed. In order to provide a merchandise carrier of the abovementioned type which is not only simple to produce and assemble, but is also secured in the display wall against unintentional detachment, it is proposed according to the invention that the substantially plate-shaped holder (1) has a U-shape cross-section and the limbs (3), facing the display wall, of the holder (1) are each equipped with at least one inward-directed guide (5), between which and the rear of the holder (1) there is displaceably arranged a locking member (6), the lower end of which is designed as a hook (7) for engaging behind a horizontally running groove or a wire bar of the display wall. By means of this configuration it is achieved that a holder, inserted into the groove of a lamella wall or between parallel wire bars of a grid wall with pushed-up locking member, is automatically fastened at its lower end to the display wall and is thus secured against unintentional swinging-up, since the locking member slides into the latched position under the effect of its weight. To remove the holder, it is necessary ... the locking member ... Original abstract incomplete. <IMAGE>

Title: Double-lipped wiper-blade device
Inventor: SAKURAI JUNJI
IPC: B60S1/38
Filed: 1989-04-24
Abstract: The invention relates to a double-lipped wiper-blade device having a lever or linkage device, to be fastened to a wiper arm, and having a rubber wiper-blade element, which is supported by the linkage device and is intended for wiping the surface, for example, of a windscreen. In the case of a wiper-blade device of this kind, the rubber wiper-blade element has a pair of rubber wiper-blade element parts, which are formed separately but are mutually combined with one another, each having an edge part running parallel to the edge part of the respective other rubber wiper-blade element part. The two lips can therefore be arranged as close to one another as desired and have a sufficient elasticity in respect of their deformation due to bending and, as a result, a favourable wiping action is produced for every vehicle speed. The two lips may be arranged symmetrically or asymmetrically with respect to their centre line in order between them to ensure uniform contact angles or uniform contact pressures.

Title: Solid electrolyte gas-sensor without ionic transfer - uses minority carrier transport to make it free of surface polarisation and able to operate at low temperature
Inventor: LIAW BOR YANN DR
IPC: G01N27/416
Filed: 1989-09-19
Abstract: The gas sensor, used to measure the gas partial pressure, consists of a solid electrolyte (1) with ions as majority charge carriers to which 2 electrodes have been attached. The feature is that inert electrode (5) is hermetic and in addition its edges have been sealed against the electrolyte surface to avoid a stationary movement of the ionic majority carriers. Electrode (3) is porous and allows the gas to come into contact with the electrolyte. The polarity and height of the DC bias is chosen to avoid a stationary ion-current in the electrolyte. Also claimed is a sensor in which a hermetically sealing covering is formed over one electrode (5). The electrolyte is pref. a flat plate of layer and the electrodes are pref. on opposite sides of this layer. The electrolyte is pref. a material which contains mobile ions of the gas to be measured, i.e. cubic or tetragonal ZrO2 or CeO2 with the hermetic electrode (5) biased negatively for oxygen pressure sensing. USE/ADVANTAGE - The cell formed shows a DC current which is carried only by the minority carriers, which means there is not transfer of ions from the gas to the electrolyte in the stationary condition. This avoids the occurrence of polarisation effects.
