Title: Circuit arrangement for regulating an intermediate-circuit converter
Inventor: LANDECK WOLFGANG DIPL ING
IPC: H02M5/45
Filed: 1981-04-03
Abstract: In order to improve the dynamic behaviour (dynamic response) of an intermediate-circuit converter (11, 12, 13) which supplies an asynchronous machine (14) and has an impressed current, a load-dependent correction of the output frequency (f1) of the converter is carried out. For this purpose, frequency regulation is provided whose reference variable (xu) is the conditioned terminal voltage (U1) of the asynchronous machine (14), which is compared with the actual value (f1) of the output frequency of the converter. The control deviation leads to the frequency (f1) being influenced as a function of the flow. <IMAGE>

Title: Apparatus for picking up and conveying excavated and bulk material
Inventor: BUTTLER ERNST
IPC: E01B27/10
Filed: 1981-04-18
Abstract: The invention relates to an apparatus for picking up and conveying excavated and bulk material, such as broken stone, sand, soil masses and even natural soil layers, in particular such which are located on non-tipping loading surfaces, e.g. on flat railway wagons. The object of the invention is to create an apparatus of the above generic category with which a large quantity of excavated and/or bulk material can be picked up from a flat loading surface, can be crushed if need be and can be specifically conveyed away in a continuous operation in as short a unit of time as possible. This object is achieved according to the invention in that it consists of a pusher vehicle (2) and a rotating bucket wheel (3), which can be advanced continuously by the pusher vehicle (2) and has buckets (18, 19) provided with openings (9, 10) at its outer and inner peripheral line (7, 8), and of a conveyor belt (4) projecting centrally into the rotary-axis area (5) of the bucket wheel (3). The bulk material (50) picked up by each bucket (18, 19) of the bucket wheel (3), at the latest upon reaching the maximum level of its centre of gravity (51), falls with gravitational force through the opening (10) of the respective bucket (18, 19) at the inner peripheral line (8) onto the conveyor belt (4). In an especially advantageous development of the invention, this bucket wheel (3) is distinguished by two working movements in opposite directions. The main uses of the novel apparatus can be seen in the unloading of bulk material on flat railway wagons on the one hand and in the crushing and picking up of natural soils on the other hand. <IMAGE>

Title: Sealed spigot-and-socket joint, secured against shear forces, on plastic pipes
Inventor: SEILER GEORG
IPC: F16L37/092
Filed: 1981-04-28
Abstract: In order to prevent a change in shape of the interengaging portions of a plastic pipe connection by cold creep of the material or the like and to achieve better absorption of the radial forces exerted by clamping elements in a sealing ring, a sleeve (110), in particular in the form of a metal sleeve, is drawn, according to Figure 1, inside into the plug-in end (102), and an expanding sleeve (114) is drawn onto the part of the sleeve delimiting the bead (105) receiving the seal. The two sleeves enclose the relevant pipe portion in the contact region (112) of the clamping elements and thus prevent migration of the material owing to the action of the clamping forces caused by cold creep, and thus also prevent a reduction in the clamping force. <IMAGE>

Title: Closure for locking the door flap of a hollow lamp standard
Inventor: TER WIEL ERIC
IPC: E05B65/00
Filed: 1981-11-21
Abstract: The invention relates to a closure for locking the door flap of a hollow lamp standard. Where lamp standards made of steel in particular are concerned, it is customary to weld inside the lamp-standard aperture a web, behind which a rotatable bolt assigned to the door flap can engage. This welding is difficult to carry out and is time-consuming. As regards lamp standards made of aluminium, material-related difficulties can arise as a result of the welding. To simplify the construction of a closure of this type and to avoid welding work, the invention therefore proposes that a bolt shaft carrying the bolt be mounted axially movably in a bush, having a bush bottom and designed as a mounting, and displaceably counter to the outwardly directed force of a spring, that the bolt be arranged on a part of the bolt shaft passing through the bush bottom and, in its locking position, bear against the inside of the lamp standard, whilst, in at least one other rotary position, the locking is cancelled, and that securing elements holding the bolt in the locking position be provided.
