Patent DE-2728418-A1 (DE)
Title: Power plant driven by unburnt natural gas - has turbine which discharges gas via after-cooler to buffer vessel formed by parallel connected large dia. pipes
IPC: F02C1/00
Filed: 1977-06-24
Abstract: Natural gas is delivered through a heat exchanger to a turbine which drives an electrical generator. The expanded gas flows through an after cooler to a buffer vessel from which it is drawn as required into a consumption system. The gas gives up its pressure energy in the turbine but is not burnt so that the calorific energy is still available at the outlet. The buffer vessel is formed by several large bore pipes which are closed at both ends and connected in parallel with the outlet pipe from the after cooler to the discharge. The outlet pipe itself is dimensioned to provide part of the buffer volume.

All shafts are accommodated in a housing near the base (1), and in the housing are sets of guide rails at right angles to the main shaft, to allow insertion of a complete station (13-17). Unions are provided for connection of the stations to adjacent supply lines (19).
Patent DE-2731587-A1 (DE)
IPC: F24S10/50
Filed: 1977-07-13
Abstract: The device for utilising solar heat has a large number of collectors (2) which are pivotable about their longitudinal axes. Each collector encloses a heat exchanger (3). Each heat exchanger has a cavity surrounded by a casing. The casing is covered by a filter covering, which behaves selectively in relation to the temperature radiation, with a specific surface exposed to the heat radiation. The casing of each heat exchanger ends with pipe pieces (43, 43') which are arranged on its end faces and which serve for supplying and removing a heat-absorbing medium. Also present are supply and removal manifold lines (41, 42) which likewise end with pipe pieces (44, 44'). Opposite each pipe piece (43, 43') of the casing lies in the axial direction a pipe piece (44, 44') of the supply or removal manifold line (41, 42), over which, to make a connection, a pipe collar (45, 45') is put. This device requires no follow-up control. It also has a simple construction, for which reason it works in a practically fault-free manner and can be adjusted effortlessly by hand. <IMAGE>

Title: Stray field compensation for railway track side control device - uses winding connected to points along current carrying line to counteract magnetic field
Inventor: STOECKMANN DIETRICH ING GRAD
IPC: B61L3/12
Filed: 1978-07-05

Title: Width stabilisation of knitted fabric during wet-treatment - by means of curved or concave rollers
Inventor: MEISEN KLAUS
IPC: D06C3/06
Filed: 1978-07-22
Abstract: Width-wise stabilisation of knitted fabric during wet-treatment, partic. mercerisation, is described where the fabric passes successively around a series of rollers arranged in two overlapping rows, whereby the form of the upper rolls is such that the edges of the fabric are squeezed against the lower rolls with a greater pressure than is the middle section of the fabric. The top roller may have a curved form which is concave w.r.t. the bottom roll, or the surface of the roller may have a concave cross-section. Alternatively, it may be of cylindrical form with edge pieces of slightly greater dia. formed from a resilient material. The process prevents the edges of the fabric from shrinking to a greater degree than the centre, and maintains a uniform stitch density across the width of the fabric. Uniform treatment across the fabric width is subsequent processing, e.g. in dyeing, is thus ensured.
Patent DE-2835865-A1 (DE)
Title: Road vehicle drive system - has three equally spaced axles with main drive to middle axle
Inventor: KLAUE HERMANN DR ING
IPC: B62D47/02
Filed: 1978-08-16
Abstract: The multi axled vehicle has the main drive on the central axle with the iron and/or rear axles driven with the torque limited with respect to that of the middle axle. The front and rear axles have no drive until the middle axle draws more than a set amount of torque so that a responsive control is achieved for steering. The front and rear axles also operate when the middle axle starts to slip so that the vehicle can move on poor grip ground. The engine is mounted at the rear. The middle drive ensures stable lateral control. The front and middle pairs of wheels are steered.
