Abstract: A method and a device for determining the weight of a load (14) transported by an agricultural tractor (10) are described. Thus, either the acceleration is determined by a speed and time measurement and, where the force of the tractor is constant, a comparison of a calibrated load with a load to be determined, or the acceleration force of the tractor (10) in the direction of travel is measured by means of a dynamometer device (36) and its acceleration in the direction of travel is measured by means of an acceleration sensor (38), and the mass or the weight of the load (14) is determined from the measurement data. <IMAGE>

Abstract: Bei einer Wiedergewinnung von auf einem magnetischen Medium gespeicherten Daten wird für die Taktierung von den Daten zugeordneten Datensignalen (D) üblicherweise ein Phasenregelkreis verwendet, der mit den Datensignalen (D) synchronisierte Taktsignale (C) erzeugt. Die Datensignale (D) unterliegen verschiedenen Verzerrungen und insbesondere einer Verschiebung einzelner Datensignale (D) in Abhängigkeit von den aufgezeichneten Daten. Um zu verhindern, daß der Phasenregelkreis diese Verschiebungen als Phasen- oder Frequenzfehler verarbeitet, wird eine Schaltstufe (F1, F2, CO, G) vorgesehen, die beim Auftreten von derartigen Verschiebungen die Regelung im Phasenregelkreis sperrt. Die Schaltstufe enthält eine Verzögerungsstufe (F1, F2) und einen Vergleicher (CO) und die Regelung wird gesperrt, wenn aufeinanderfolgend Phasendifferenzen zwischen den Datensignalen (D) und den Taktsignalen (C) in entgegengesetzten Richtungen auftreten.

Abstract: A semiconductor device contains a stress-relief layer (46) having a glass transition temperature below 150°C. The layer generally lies above an electrical interconnection system (12) in the device but does not overlie bond pad areas. This substantially alleviates thermally induced stress that could otherwise damage electronic components in the device while simultaneously allowing the maximum stress on electrical conductors (32 and 34) that protrude from the external package coating (48) to occur at bonding areas which can tolerate the stress. The layer is preferably made by lithographic patterning.

Abstract: A display assembly (Fig. l) comprises a plurality of panels (l) joined together by elongate connecting members (2, 3). Each panel has a removable frame formed by extrusions (6) in each of which is a slot (l3) having a restricted entrance (Fig. 2). Each connecting member (2, 3) has two heads (l8) which can be slid into slots (l3) in adjacent panels (l), from one end, to join the panels together, each head being too wide to pass through the restricted entrance of the slot. A central body portion (20) of the connecting member, to which the heads (l8) are joined, is positioned between, and extends outwards between, adjacent panels to facilitate access to the connecting member and en­able the screen assembly to be dismantled easily. A longitudinal slot (50), (Figs. 2l to 23), can be pro­vided in a part of the body (20) that is accessible between connected panels, to enable components such as shelf-supporting brackets to be secured to the screen assembly. To increase the versatility of the assembly, a variety of connecting members (Figs. 4 to l2) can be provided, enabling panels to be joined together in a common plane or in planes inclined to one another and in one or more tiers, and the assembly can also include panels connected together by poles (34) and clips (35) (Fig. l6). The connecting members (2, 3) can be extended components and may be of hollow cylindrical construction (Figs. l0 and ll).

Inventor: HOUCHIN MARTIN RICHARD
IPC: C01G25/06
Filed: 1987-10-13
Abstract: A process for the preparation of zirconium sulfate tetrahydrate. This process involves the leaching of a zirconium source with sulfuric acid and the formation of a zirconium sulfate tetrahydrate by the dilution of the slurry produced by the leach. The process further provides for the reconstitution of the acid diluted to produce the zirconium sulfate tetrahydrate once the zirconium sulfate tetrahydrate has been crystallised and removed from the diluted acid. The reconstituted acid is then recycled to the leach step. This process may include various purification techniques. The process allows for the preparation of zirconium sulfate tetrahydrate wherein waste sulfuric acid produced as a byproduct is minimized.

Abstract: The invention relates to a piezo-ceramic device for acoustic waves. Electro-acoustic devices include, for example, electrical filters, oscillators, resonators and delay elements. The piezo-ceramic material exhibits a depolarised zone (18). The depolarised zone (18) effects a change in the velocity of sound along the propagation path (14) of the device, and thus a change in the frequency characteristic or the delay time. The method for producing the device is characterised by the fact that the piezo-ceramic material is locally heated above its Curie temperature. The arrangement of depolarised zones (18) in the piezo-ceramic material makes it possible to produce, in a simple manner, precision devices having a wide bandwidth and low insertion loss. <IMAGE>
