Title: Hinge arm for a furniture hinge or the like
IPC: E05D7/12
Filed: 1987-07-29
Abstract: The hinge arm has a U-shaped profile and can be used in baseplate guides. Optionally, it can be mounted on a baseplate having a threaded hole for a fixing screw by means of said screw. Preferably, however, it can be locked by means of an intermediate plate to a baseplate having a stop and a cushioned hook-type latch projection which snaps in behind a holding edge of the hinge arm or possibly the intermediate plate. In order to be able either to mount the hinge arm on a standard baseplate with a fixing screw without additional modifications or to lock it to a baseplate with a snap-in fastening device, the holding edge is formed by an already existing edge of the hinge arm or the intermediate plate.

Abstract: A transistor (30) constructed in accordance with our 
invention includes a substrate (31) of a first conductivity 
type and first and second regions (32, 33) of a second 
conductivity type formed within the substrate. A gate 
(30g1) is formed over the portion of the substrate between

either a first mode, in which the first region serves as a 
source and the second region serves as a drain, or a second 
mode, in which the first region serves as a drain and the 
second region serves as a source. During the first mode, 
the substrate is coupled to the first region and during the 
second mode, the second region is coupled to the substrate, 
thereby permitting the transistor to operate in forward or 
reverse mode, while still biasing the substrate.

Title: Refuse vehicle
IPC: B65F3/20
Filed: 1988-06-29
Abstract: In refuse vehicles having a refuse-filling system arranged behind the driver's cab, an adjacent refuse-compressing device and a refuse-collecting container arranged behind the latter, it was hitherto not possible to achieve adequate compression of the filled refuse inside the refuse-collecting container, resulting in insufficient utilisation of said container. 
<??>In the case of the invention, there is arranged in the range of action of the refuse-compressing device a counterpressure plate which can be subjected to a pressing force and is mounted in a radially swivellable manner on the ceiling of the refuse-collecting container, said plate forming a counterpressure element for the filled refuse. In this way it is possible to compress, in a uniform manner, the refuse filled into the refuse-collecting container from the start of refuse feeding until said container is completely full and thus an increased utilisation or useful load of the refuse vehicle can be achieved.

Title: Data buffer apparatus and method
IPC: G06F5/06
Filed: 1988-08-11
Abstract: An improved First-In, First-Out data buffer and method 
of operation incorporates a plurality of arrays of 
random-access memory cells in column and row orientation per 
array in which all the cells in a row of one array are 
precharged simultaneously as memory cells are accessed for read 
or write operations in another array. Also, all the cells in a 
row of the other array may be precharged as the memory cells in 
the one array are accessed independently for read or write 
operations. Accesses to memory cells in addressed rows 
alternate from one array to another so that the signal 
conditioning of the memory cells in one array can take place 
before access in needed and while memory cells are being 
accessed in another array. Improved status logic unambigously 
designates the conditions of empty, half full and full, 
independent of the sequence of data read and write operations. 
Data signal driver circuitry controls the rate of change of 
data output signals for improved noise performance and 
compatibility with external circuitry.

Abstract: A progressive-multi-focus lens (1, 5) for constituting 
spectacles having long-distance and short-distance focuses, 
having an area in which the refracting power progressively 
changes (successively increases) from upper to lower

shifted upward as the strength of the lens is reduced, 
thereby optimizing the performance of the lens for a 
particular user.

Title: Magnetic sensor
IPC: G01V3/08
Filed: 1989-09-27
Abstract: A casing is produced by bonding a base plate (7) to a cap (8) 
and sealing the bonded portion (A) so as to keep the interior of 
the cap (8) in an air-tight state. A magnetic detector (5) is 
disposed in the cap such that the magnetic detecting surface (5a) 
of the magnetic detecting element (5) constituting the magnetic 
detector is in contact with the ceiling of the inner wall of 
the cap (8) and a holder (4) for holding the magnetic detecting 
element (5) is separated from the upper surface of the base 
plate (7). When the base plate (7) is engaged with the cap (8), a 
lead-out terminal (17) from the magnetic detecting element 
presses the terminal (18) provided on the base plate side direct­
ly or indirectly through a conductive material. Since the 
detecting surface (5a) of the magnetic detector is constantly in 
contact with the ceiling of the inner wall of the cap (8), the 
magnetic detection accuracy is enhanced and the electrically 
connecting operation of a lead-out terminal from the magnet­
ic detecting element is greatly facilitated.

and coding unit arrangement which in turn contain the 
coding units (70-73). Each switching device contains logical 
gates and a bistable circuit for latching the chosen 
relection of the coding units.
