Title: Speed and power control for turbine set - feeds output of proportional integrator back to input of adder
Inventor: BASNIN OLEG ILIC
IPC: H02P9/04
Filed: 1980-04-11
Abstract: The speed and power control has a proportional integrator coupled to the output of an adder and to the input of the drive's control device. The adder adds the outputs from a tachometer describing the turbine set's speed, from a reference generator (producing a signal describing the desired speed of the set) and from a feedback device. The feedback device's output may be switched directly through to the adder or via a low pass filter. The feedback device passes the output of the integrator back to the adder. The adder's output is added to the reference signal and the sum passed via a limiter to the input of the integrator.

Title: Automatic pipe-circumference welding apparatus
Inventor: MUKUDA MUTSUO
IPC: B23K37/02
Filed: 1981-02-13
Abstract: An automatic welding apparatus is described which comprises a curved frame which has a welding unit and two wire-feed devices as well as a curved frame which has a carriage and two clamping mechanisms for fastening the outer circumference of a pipe to be welded. The two abovementioned curved frames are releasably connected at two positions so that in this way they form a ring shape. Consequently, the pipe is automatically welded while the carriage is allowed to run in the circumferential direction. The carriage of the welding apparatus constructed in this way carries both a mechanism for bringing about close contact with the outer circumference of the pipe as well as a shock-absorbing mechanism so that the distance between the leading end of a welding torch and the outer circumference of the pipe can be kept constant at all times. In addition, the clamping mechanisms can be actuated electrically so that they can be manipulated with ease. The welding torch and two wire-feed guides are provided as the welding unit. The leading ends of the wire-feed guides face the welding torch so that multi-layer welding operations are thereby facilitated.

Title: Process and installation for the automatic moulding and production of concrete elements
Inventor: KRUESSEL GERHARD
IPC: B28B13/02
Filed: 1981-07-02
Abstract: The invention relates to a process for the automatic moulding and production of concrete elements and also to an installation for carrying out the process. The invention is based on the object of providing a process and an installation by means of which the fresh concrete of the concrete element is reinforced and, while at the same time undergoing vibration, is worked in such a way that the concrete element is given a uniform material structure and a surcharge lies uniformly and continuously on top of it. The invention achieves the object by a guide trough being lowered onto the mould by means of a supporting frame until the edges of its levelling base rest on the end faces of the mould, into which inserts, preferably reinforcing elements, have been placed beforehand. After this, the levelling base of the guide trough above the mould is opened completely. With the levelling base completely open, the fresh concrete is distributed over the entire surface area of the mould in two directions in the same plane, while at the same time undergoing vibration, and the guide trough is lowered to such an extent that it is connected to the mould. During this operation, the mould is filled to excess to such an extent that the compacted fresh concrete extends beyond the mould and a first excess of concrete is formed. When the levelling base is closed, the concrete in the mould, having a uniform, compacted excess, is struck off and levelled, the levelling base is disposed on the end face of the mould and a surcharge is applied after striking off the concrete and moving the spreading device in a way known per se up to the side formwork of the mould. <IMAGE>

Patent DE-3147451-A1 (DE)
Title: Wire feed device
Inventor: BEURENMEISTER OSKAR
IPC: B23K9/133
Filed: 1981-12-01
Abstract: The wire feed device according to the invention comprises a housing in which two gripping means situated axially one behind the other are connected, in each case via a connecting part designed as a rod, to a displacement body. For this purpose, the said body has a circumferential groove in which the connecting part is guided by rolling bearings as in a slotted link. The wire to be fed to a welding system or the like is guided between spherical gripping elements coaxially to these parts of the means. The gripping elements each lie in the same plane, radially to the wire, in a frustoconical recess in a receptacle of the gripping means. When the displacement body is rotated, the oblique circumferential groove has the effect that one of the connecting parts is alternately displaced forwards with the associated gripping means in the feed direction of the wire or backwards, the gripping elements releasing the wire or being made to rotate and, as a result, taking the wire along in the feed direction.
