Patent DE-3147261-A1 (DE)
Title: Vane pump
Inventor: MOTT ROLAND DIPL ING
IPC: F01C21/08
Filed: 1981-11-28
Abstract: A vane pump, which as displacement element has rollers (6, 7) in a slot (5), has pressure chambers (12, 13) on both end faces of its rotor (3), which chambers are connected by way of axial bores (16, 17) to the chambers in the slot (5) between the rollers (6, 7) and the axis (4) of the rotor (3). In this way the rollers (6, 7) can deliver fluid from the chambers between the rollers (6, 7) and the axis (4) through the pressure chambers (12, 13) into the corresponding opposing chambers between the rollers (6, 7) and the axis (4). In addition the rollers (6, 7) on the vane pump are narrower than the height of the rotor (3) and held axially in the rotor (3). Owing to this design the vane pump functions particularly noise-free and with little friction. <IMAGE>

Title: Process and apparatus for the finishing treatment of continuous textile webs and the like
Inventor: TISCHBEIN CLAUS DIPL ING
IPC: D06C27/00
Filed: 1982-05-21
Abstract: The invention relates to a process and an apparatus for the finishing treatment, especially bulking, compression (shoving) and improvement in feel of continuous textile webs, such as webs of woven and knitted fabric and the like, and have the object of providing a process and an apparatus for carrying out a process, by means of which fully continuous operation becomes possible. For this purpose, there is proposed, according to the invention, a process, in which the webs, after being impregnated with an effect-promoting treatment fluid and subsequently drained to a moisture content optimum for the subsequent treatment, are subjected first, in the relaxed state, to a fulling treatment and thereafter, likewise in a largely relaxed state, to one or more shoving or beating treatments, whereupon further treatments, such as washing, drying and the like, of the webs then take place. The apparatus can be designed in such a way that the shoving or beating treatments are carried out by means of beating devices, in which the cloth webs are guided past stationary beating strips and, at the same time, are shoved against the beating strips for a short time by means of rotating elastic beaters. <IMAGE>

Patent DE-3231732-A1 (DE)
Inventor: MARSCHALL PETER
IPC: H01L21/60
Filed: 1982-08-26
Abstract: Ein Flüssigkristall-Sichtgerät soll derart beschaffen sein, daß es bei großem Informationsumfang einen raschen Informationswechsel unabhängig von der Umgebungstemperatur bei möglichst geringem schaltungstechnischen Zusatzaufwand für die Sichtgerät-Ansteuerung ermöglicht. Dafür wird ein nematisches Flüssigkristall-Material - vorzugsweise mit verdrehter Phase und gegebenenfalls mit Zusatz dichroitischer Farbstoffe - gewählt, das bei Ansteuerung seiner Elektrodengruppen-Paare mit einer Frequenz oberhalb eines materialspezifischen Übergangs-Frequenzwertes eine dielektrische Anisotropie anderen Vorzeichens aufweist, als bei Ansteuerung unterhalb jenen Übergangs-Frequenzwertes, mit umgebungstemperaturabhängiger Verschiebung des Übergangs-Frequenzwertes. Dadurch kann die Ansteuerung mit unabhängig von der Umgebungstemperatur fest vorgegebenen Frequenzen und Amplituden erfolgen, weil die Vergrößerung des Betrages der dielektrischen Anisotropie bei niedrigeren Umgebungstemperaturen höhere Rückstellfeldkräfte erbringt. Anwendung beispielsweise bei großen im Freien installierten, also starken Umgebungstemperaturschwankungen ausgesetzten Anzeigetafeln, etwa für die Verkehrslenkung oder in Sportstätten.

Title: Electronic computer
Inventor: PITZ HARALD H
IPC: G06F19/00
Filed: 1982-09-11
Abstract: To detect the present individual blood alcohol content, it is proposed to use an electronic computer the main memory of which stores the blood alcohol values in units per mil and the memory content of which is increased, on the one hand, by inputting new blood alcohol quantities and, on the other hand, is automatically reduced by particular per-mil values at particular time intervals. Such a computer can be constructed to be extremely compact due to the simple logic and the low memory capacities, and provides any alcohol consumer with a simple possibility of determining his individual blood alcohol level at any time by simply inputting the quantity of alcohol and his body weight. <IMAGE>
Patent DE-3235020-A1 (DE)
Title: Chemisorption process for absorbing preferably sulphur dioxide downstream of power stations, refuse incineration plants and the like
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/56
Filed: 1982-09-22
Abstract: The invention relates to a combined gas drying and chemisorption process for removing SO2, HCl, HF, NOx and similar pollutants from untreated gases downstream of power stations, refuse incineration plants or the like. A disadvantage of the known plants is that acid constituents possibly containing drop-like acidic moisture components penetrate the fibrous filters used in this process with the consequence that corrosion is unavoidable. To avoid this, the invention proposes that the untreated gas is fed into a suspension reactor (2) whose outlet is connected to a dry reactor (3) to which fresh lime (6) is fed, the lime being transferred to a precipitator, preferably a fibrous filter (4) and the used chemisorption agent (7), for example used lime, being fed to a suspension mixer (8) in order to be fed from that point to the spraying tower (2). The chemisorption agent (9) discharged can be reused or delivered to a waste-disposal site. <IMAGE>

Title: Toy for combination games and puzzles
Inventor: HOFGARTNER ERWIN
IPC: A63F3/00
Filed: 1982-11-18
Abstract: Playing surfaces (72) are applied to both sides of a combination body designed as a playing board (71), in that mushroom-shaped guide ties (79) composed of a flange plate (81) and of a guide shank (82), and guide ties (83) half as wide at the edges, are formed with an equal division between row slots a, b, c, etc. and column slots 1, 2, 3, etc.. The centre of all the coordinate zones is determined by the intersection of row and column slots, in which play segments (99) are displaceably guided, by means of their holding tie (103) consisting of a foot plate (104) and tie neck (105), so as to be secure against being lifted out. Their head plates (101) cover in each case one coordinate zone. In multiple play segments (112, 118), in each case a plurality of coordinate zones are covered and a corresponding number of holding ties (103) is provided. Some play segments are provided with direction markings (119) which give a rule of arrangement by being joined together (121). By rearranging and, if appropriate, by rotating the play segments in the coordinate positions or outside the playing surface, a new order can be provided by reorientation and discarding. A plurality of combination carriers can be connected by means of coupling strips (111) which can be inserted into edge grooves (108), row grooves or column grooves. <IMAGE>

Title: Connection fitting for water meters with a shut-off member for the water supply
Inventor: JAEHRLING HORST
IPC: G01F1/05
Filed: 1982-12-27
Abstract: The invention aims to provide a connection fitting for water meters designed, for example, as cylindrical piston water meters, in the case of which fitting the shut-off member for the water supply is neither designed as a handwheel, nor does it require a screwdriver as an actuating means. The elimination of these two prior-art means of release and the replacement by a novel one is achieved, as represented in the drawing, in that the connection fitting is composed of a bottom part which is arranged in a fixed manner, is screwed into the water-line valve housing and has an outer flange, a coaxial through-flow channel and one or two further through-flow channels in the vicinity of its border, and of a rotatable top part which can be connected to the water meter, is guided on the outer flange by means of a union nut and has the same through-flow channels as the bottom part. <IMAGE>

Title: Machine with automatic operating sequence for producing spiral springs
Inventor: BOBBIO BENEDETTO
IPC: B21F3/00
Filed: 1983-02-19
Abstract: This is a machine with an automatic operating sequence for producing spiral springs (helical springs, conical springs, springs with fixed or variable pitch, double conical springs, etc.), whose operating run is carried out by servo controls. This machine mainly comprises a first motor which drives the wire feed rollers, a second motor which drives a shaft bearing control cams, and a third motor which controls a tool for separating the finished spring. In particular, the rotary speeds of the first and of the second motor are adapted to one another via a synchronisation device, whereas a pulse generator connected to the first motor measures the unwinding of the wire and brings about the stoppage of said motor as soon as the spring has reached the predetermined length. The control cams not only bring about the cutting-off of the springs and not only determine the pitch and the diameter thereof, but they also function in such a way that the initial states of the operating run are restored again, that this restoration is suppressed in the case of producing conical springs until a second cut has been carried out which removes the deformed portion of the wire, that the first motor is controlled to draw off said wire portion to be cut off, and that an end cycle microswitch is actuated. Furthermore, the supply of the motor driving the wire feed rollers is subordinate to a series of potentiometers, by means of which the rotary speed of the motor can be set. It is indeed possible by these measures to obtain absolute accuracy in the dimensioning of the product and also to change said dimensioning directly by intervention on a corresponding control panel without previously having to shut the machine down.
Patent DE-3306426-A1 (DE)
Title: Connection for mullions (crossbars) in plastic windows which are produced from plastic hollow sections having intercalated reinforcing strips made of steel or aluminium
Inventor: ZETTNER WERNER
IPC: E06B3/964
Filed: 1983-02-24
Abstract: The connections known to date for mullions in plastic windows have required a high expenditure on assembly and have not increased flexural strength. Both problems are substantially improved by the abovementioned invention. Flexural strength is achieved by tensioning the reinforcing irons (which are in the plastic section). The flexural strength thereby allows higher or wider windows without additional reinforcement from the outside. The lower expenditure on assembly is achieved in that the connecting parts are constructed only of three individual parts, as characterised in the attached drawing Fig. 3 section No. 1-3, and no additional drilling from outside is necessary. (Provided by the large screw head.)
