Title: Needle-selection device for a circular knitting machine
Inventor: SAWAZAKI MASATOSHI
IPC: D04B15/68
Filed: 1981-12-17
Abstract: In a circular knitting machine, in every row of circularly arranged slots in a rotating cylinder (1), an intermediate needle-stroke lever (4) is provided between a latch needle (3) and a selector lever (5). The needle-stroke lever (4) is pivotable on the bottom face (2a) in the associated slot (2) about a centre of rotation (44) and is movable in the longitudinal direction in the slot, whilst the selector lever (5) is only pivotable in the slot (2). The selector levers (5) are guided into a selection position and a rest position under pattern control, with the result that the needle-stroke levers (4) are brought into the lifting position and into the rest position. A cam (34) acts on the needle-levers (4), in order to bring their pivot points (44) flexibly into contact with the bottom face (2a) of the slots (a). A magnet unit (36) keeps the selector levers (5) flexibly in their rest position, in which they execute no selection activity, whilst at the same time a selection is carried out among them. <IMAGE>

Title: Regulation of the network power factor of converter-supplied synchronous machines
Inventor: VOIGT HANS-HERBERT DIPL ING
IPC: H02P25/024
Filed: 1982-02-11
Abstract: In order to relieve the load on the supplying network (L1, L2, L3) from the fundamental and harmonic reactive power during operation of a synchronous machine (4) via a converter which is constructed from a network converter (1), a DC intermediate circuit and a machine converter (3), a variable desired value is predetermined for the hold-off interval regulation of the machine converter (4). This desired value is predetermined as a function of the regulation deviation of the reactive-power actual value from the reactive-power desired value at the network converter (1), in such a manner that the machine delay angle (x) and hence the power factor are influenced such that the reactive power on the network side assumes a predetermined value irrespective of the rotational speed and load. This value can be constant, or can be variable as a function of specific network variables or the switching state of an associated solid-state compensation device (24). <IMAGE>

Title: Rearview mirror system for vehicles
Inventor: SCHUWERK FRITZ
IPC: B60S1/56
Filed: 1982-03-31
Abstract: In a rearview mirror system for vehicles which has a mirror surface, at least one partial surface of which can be made to rotate in order to keep it free of moisture and dirt, according to the invention compressed air is used as drive means for this rotational movement, which air is fed out of the vehicle's own compressed air source to a guide channel leading to the rotatable partial mirror surface, by which means a satisfactory rear view can be ensured in every driving state. The compressed air is preferably branched off from an excess of compressed air which occurs in particular in driving operation in a compressed air-operated vehicle brake system. In addition, if appropriate a heating device can be connected in the flow path of the compressed air from the compressed air source to the rotatable mirror surface so that the mirror surface can be heated with heated compressed air. In addition, a windscreen wiper and a heating device for vehicle windows located in the line of sight to the mirror surface can be supplied with the compressed air which is removed from the compressed air source of the vehicle and possibly heated. The compressed air is preferably heated in a heat exchange with the exhaust air from the vehicle engine. <IMAGE>

Title: Loosening device for sluggishly flowing bulk materials
Inventor: SCHAEFFER ERICH DIPL ING
IPC: B65D88/66
Filed: 1982-05-06
Abstract: The patent application relates to a loosening device for sluggishly flowing bulk materials for exciting and maintaining the flow of bulk material in bunkers and containers, formed from guide plates pointing radially outwards to the container wall, set in vibration by at least one vibration generator and displaced elastically relative to the container by means of springing elements, a plurality of arms extending towards the guide plates obliquely downwards and outwards, that is to say as seen in the direction of flow of the material, from a central region lying on the vertical axis. The arms then run vertically along on the guide-plate end faces on the outside and are curved inwards again further below. The loosening device thus corresponds essentially to a spider-like structure which, by vibration generation, excites the surrounding bulk material to a favourable flow behaviour.

Patent DE-3309923-A1 (DE)
Title: Heat exchanger
Inventor: BAEHR ROLF DIPL ING
IPC: F24S10/70
Filed: 1983-03-19
Abstract: The invention relates to a heat exchanger having a ductwork through which a heat carrier flows and which has at least one manifold and a duct part which is connected thereto and is composed of a hose extending in a meandering form. The ductwork of a known heat exchanger consists of a multiplicity of mutually parallel and comparatively short duct pieces. Two groups of these duct pieces are arranged extending at right angles to one another. All hose ends have to be connected to manifolds and distributing manifolds. This results in a very complicated production and a design that is architecturally very unsatisfactory in conjunction with a low capability to adapt to the environment. By contrast, the invention proposes that the ductwork is constructed in the manner of a fabric in which the hose serves as the weft. The fabric facilitates secure fixing of the hose, while, because of its structure and the elimination of supporting structural parts, the woven duct path is architecturally attractive and can be very effectively adapted to the conditions.
Patent DE-3316081-A1 (DE)
Inventor: AFFA ALFRED ING GRAD
IPC: G01B21/02
Filed: 1983-05-03
Abstract: A measuring system for measuring the relative position of tool machine parts compensates for thermally-induced length changes of a spindle stock by means of a scale carrier which acts as an expansion element for a scale. This scale carrier is fastened at one end directly via a fastening element to the spindle stock and at the other end is connected with an adjacent end of the scale, which is mounted on the scale carrier so as to be shiftable in the measuring direction. If the plane of the tool connected to the spindle stock shifts by an amount  DELTA c in the measuring direction X as a result of temperature rises of the spindle stock, the scale carrier, operating as an expansion element, acts to pivot a rotatable element having an adjustable lever ratio in order to shift the scale in the same direction. In this way, the entire thermally-conditioned displacement of the scale is also made to equal the amount  DELTA c.

Patent DE-3330103-A1 (DE)
Title: Rig for sailboards and sailing vessels
Inventor: SCHWEISSER ROBERT
IPC: B63H9/06
Filed: 1983-08-20
Abstract: This rig is a structure which is intended to guarantee better handling and greater efficiency of the sail. This is achieved by setting the sail area higher in the region of higher wind speeds and by the use of a basic quadrilateral sail shape braced by means of a mast and boom structure towards four corner points. Turns are substantially simpler to execute due to the action space which has arisen under the raised sail area. The mast and boom structure used permits better handling than previously. The utilisation of the higher wind speed and the use of aerodynamically favourable quadrilateral sail shapes increase the efficiency of the sail.
