Patent DE-3327064-A1 (DE)
Title: Apparatus for continuous heat treatment, such as drying, of lengths or strips of textile material
IPC: F26B21/04
Filed: 1983-07-27
Abstract: The apparatus relates to a hot flue construction in which the treating air is fed in and also withdrawn within the loops (see the Main Application P 3323827.8). This advantageous guiding of air for uniform heat treatment of lengths of material over their width is operated within a housing with two hot flues arranged one above the other and with only one radial fan for the treating air which is to be circulated. Nevertheless, it is possible to act in the upper hot flue on the already predried length of material guided about the deflecting roller there, with an air supply other than that for the length of material running in at the bottom, where a higher air humidity is present.

Title: Indexable insert with chip-forming and chip-breaking recesses
Inventor: WAGNER MANFRED
IPC: B23B27/14
Filed: 1983-09-12
Abstract: The invention relates to a sintered-carbide indexable insert with chip-forming and chip-breaking recesses for machining, in particular for turning metal workpieces. The aim of the invention, using a novel indexable insert, is to design the cutting process to be more economical with regard to the expenditure of energy and to improve the quality with regard to the machining result. The object of the invention, for indexable inserts with chip-forming and chip-breaking recesses, is to develop a novel shape of these recesses, which make possible improved cutting ability and chip breaking. This object is achieved according to the invention in that each chip-forming and chip-breaking recess consists of a cutting face in the form of a cylindrical surface area and a chip-breaker face in the form of a conical surface area, in which arrangement recesses lying in mirror image to one another and consisting of cylindrical surface areas and conical surface areas are located between the two corners defining a cutting edge, which recesses are separated from one another in the region of the centre of the cutting edge by a chip-hollow-like recess consisting of a cylindrical surface area and a conical surface area. <IMAGE>
Patent DE-3333759-A1 (DE)
Title: Automatic electrical switching on and off device for voltage converters
Inventor: BRIECHLE HERMANN
IPC: H02J9/06
Filed: 1983-09-19
Abstract: In order to be able to operate a voltage converter as a standby power generator without control elements, said converter must be equipped with an automatic switch which consumes so little current on no-load that the complete converter-switch system can remain continuously connected to the power source. For this purpose, a generator supplies needle pulses which are induced in the output circuit by the power transformer of the converter and are always transmitted from there via a control transformer into a switching stage, when a load is connected. The switching stage causes the control part of the converter to switch on and bridges over the separation between the needle pulses during the cutting-off delay. In order to make the power transformer suitable for the transmission of needle pulses, its core must be demagnetised during the cutting-off process. If it is undesirable to have needle pulses in the output voltage, the amplitude of the needle pulses can be reduced in the pulse generator while the converter is switched on.
Patent DE-3338491-A1 (DE)
Title: Sail arrangement for watercraft
Inventor: TITAU REINHOLD
IPC: B63H9/06
Filed: 1983-10-22
Abstract: The general aim of the invention is to utilise the wind force more effectively for the propulsion and to be able to use relatively larger sail areas. This is achieved by three measures:   1. by a sail combination, e.g. fore sail and main sail, being fixed in their position relative to one another and by being fastened to a mast which can be rotated about its own axis through at least 300 DEG  relative to the hull; 2. by the mast being able to perform rotary/pendulum movements about a point lying in its axis, by means of which movements the mast tip and the mast foot describe spatial circular or elliptical paths and the sail, on any course, can be put into a position relative to the wind in which it produces propulsion and buoyancy and prevents capsizing; 3. by the sail being given an aerodynamically favourable profile which is independent of the sail position, and in fact by connecting the bottom edge of the sail to a leaf spring instead of to the boom, which leaf spring is fastened to the mast at a fixed angle and can be profiled by trimming sheets like an arc through a chord.

Patent DE-3342901-A1 (DE)
Title: Back-pressure control valve
Inventor: WEBER KLAUS
IPC: G05D16/10
Filed: 1983-11-26
Abstract: The invention relates to a back-pressure control valve with a housing which has at least one inlet opening which is connected to a source of fluid, and furthermore has at least one outlet opening, via which a first fluid supplied by the source of fluid is mixed with a second fluid, the pressure of which is present at the outlet opening, the inlet and outlet opening being connected via a valve controllable as a function of pressure, the valve-closing member of which is guided displaceably in a hole formed in the housing and is preloaded in the closing direction against the pressure of the first fluid by a spring. In pumps of various designs, a reduction in the delivery rate occurs with increasing output pressure. In order to avoid this disadvantage, the back-pressure control valve is designed in such a way that the spring is supported against a piston arranged displaceably in a chamber which is formed in the housing and is divided by the piston into a pressure chamber and a spring chamber in which is arranged a pre-loading spring supported against the piston and assisting the pre-loading force of the spring, and the pressure chamber is supplied with the pressure of the second fluid, as a result of which the total pre-loading force acting on the valve-closing member in the closing direction is altered by the pressure of the second fluid in such a way that a constant back-pressure is established for the source of fluid. <IMAGE>

Patent DE-3405551-A1 (DE)
Title: Circuit arrangement having several signal transmitters
Inventor: MAHECHA-ORDONEZ HECTOR DIPL IN
IPC: G08B29/16
Filed: 1984-02-16
Abstract: Several signal transmitters (G1, G2) generate identical electrical transmitter signals. Via a diode circuit (D1 to D4), it is achieved that in each case the greatest positive and negative transmitter signal is supplied to a subsequent evaluating device (AE), there being no reaction to the other transmitters (G1, G2). By using operational amplifiers (O1 to O4), the threshold voltage of the diodes (D1 to D4) is corrected. This makes it possible still to detect the measurement quantity in the evaluating device (AE) by means of a single signal transmitter (G1, G2) when individual signal transmitters (G1, G2) fail. <IMAGE>

Title: Pistol-shaped injection syringe
Inventor: TEICHMANN HORST F
IPC: A61M5/315
Filed: 1984-03-09
Abstract: There is an injection syringe in which a front endpiece (15) of a piston rod (8) projects into an ampoule (19) in which there is located a piston (17) having a cavity (16) with a butt (17), the ampoule is received by a protective covering (22), and a locking disc (12) sits at the rear of the piston rod (8). It is desirable after a minor change of the syringe shape for the piston to be able automatically to move back slightly after an advance step due to simpler operation. This is achieved in that the front endpiece of the piston rod (8) is designed as a mushroom (15) which can be pressed into the cavity (16) with the butt (17), the ampoule (19) rests at the rear against an abutment (21) of the protective covering (22) and the locking disc (12) carries a laterally projecting flap (25). Aspiration can now be done automatically with only one hand and with the injection needle being held extremely steadily by means of the relaxing spring by pressing on the flap (25) and releasing the operating arm (5). <IMAGE>

In order, at the same time, to guarantee a fixed fastening of these articles in the device, the lowest resting surface of the bearing element is curved convexly in relation to the plane of the base area of said bearing element and, in the fitted-together state of the elements, applies spring force to the article accommodated in a sealed manner in the device against the underside of the lowest resting surface of the fitted-on element.
Patent DE-3414856-A1 (DE)
Title: Method and arrangement for processing measurement signals for obtaining summary characteristics
Inventor: VOLLATH DIETER DR
IPC: H03M1/04
Filed: 1984-04-19
Abstract: During the processing of measurement signals from a multiplicity of individual measurement values, as in the processing of television images, the measurement signals are converted by an analog/digital converter and, following this, a considerable expenditure, particularly of time, is required even for determining summary characteristics such as mean values, standard deviations and so forth. To avoid, in particular, the time expenditure and possibly allowing a real-time evaluation of the measurement signals, it is proposed that at least one noise signal is generated, that each measurement signal is compared with at least one noise signal and that a sequence of output pulses is generated in accordance with predetermined relative relation of the respective values of measurement and noise signal compared with one another, this being done by means of an arrangement in which at least one noise generator (11, 12) and at least one comparator (6) is provided which is supplied with a measurement signal (7) and a noise signal generated by the noise generator and which outputs binary output pulses (16). <IMAGE>

Patent DE-3434203-A1 (DE)
Title: Vertically movable partition curtain
Inventor: CLAUSS MANFRED
IPC: E06B9/24
Filed: 1984-09-18
Abstract: A vertically movable partition curtain for halls contains two curtain webs which are anchored along their upper edge under the hall ceiling and which are interconnected by a large number of transverse cords. For drawing up, vertically extending pull belts run between the curtain webs, which belts are connected with their lower end on the lower edge of the curtain webs and the upper end of which is anchored on a respectively associated winding-up roll. By means of a drive device, the winding-up rolls can be set in rotation. In order to avoid an undulating course of the curtain lower edge, for example as a result of different length of the belts, means are assigned to each winding-up roll, by means of which a respective winding-up roll can be set in rotation or stopped independently of the other. Also assigned to each winding-up roll is a limit switch device, by means of which, on reaching the upper or the lower end position of the associated pull belt, the means assigned to the corresponding winding-up roll can be actuated with a stopping effect.
Patent DE-3435481-A1 (DE)
Title: Corner connector
IPC: F16B12/46
Filed: 1984-09-27
Abstract: Corner connectors are used in furniture construction because of the simple and reliable connection capability. In order to prevent a wide range of types with respect to the different requirements, the corner connector (1) according to the invention can be used for the most varied corners which result from the various types of furniture. By means of the three stop surfaces (2), which are mutually perpendicular and together form a corner angle, it is possible to connect any panels which form corners with one another. The corner connector (1), which is constructed as a solid component, can be used particularly easily if a threaded hole (3), into which a screw (4) can be turned is incorporated in the region of each stop surface (2). It is particularly advantageous if the free surface adjacent to the stop surfaces (2) is of convex shape since, in consequence, the corner is filled and the cleaning of the boards is simplified. <IMAGE>
