Patent DE-3223177-A1 (DE)
Title: Process and device for the utilisation of wind energy
Inventor: APKE MARTIN DIPL ING
IPC: F03D5/06
Filed: 1982-06-22
Abstract: In order to obtain energy economically even at low wind speeds and from winds occurring irregularly and in gusts, the particular wind power obtained is intercepted by means of a wind resistance body and transmitted to a hydraulic cylinder and then, by means of a hydraulic line connection, to the energy consumer or energy consumers. The energy conversion losses occur only at the consumer where they can easily be utilised for other purposes. The wind resistance body having a relatively large wind engagement surface executes to-and-fro movements in the wind, the return against the wind direction taking place as a result of the opening of integrated flaps or, in pauses in wind power, by dead weight or even spring force. The wind resistance surface always acts perpendicularly to the wind direction. The movements of the resistance body are slow and the actual wind speed is to be equated approximately with the effective wind speed. Moreover, as a result of the slow movements, little kinetic energy is consumed and a sensitivity even to brief gusts of wind is achieved. Energy storage takes place at the consumer in the form of use of the latter.

Title: Electromechanical short-interval timer
Inventor: FLAIG HANS ING GRAD
IPC: H01H43/10
Filed: 1982-07-28
Abstract: In the case of an electromechanical short-interval timer having a pointer toggle (4) which can be moved out of its quiescent position manually and can be moved back into its quiescent position (11) by a motor (9) such that an electro-acoustic transducer (19) can be switched on before said quiescent position (11) is reached, it is intended to increase the functional reliability and improve the ease of use at a reduced design cost. To this end, the signal-output duration is controlled via the transducer (19) by a timing circuit which is started via a contact-making bending spring (20) when the pointer toggle (4) runs into its quiescent position (11). This timing circuit also starts a timing circuit - preferably the same and constructed within the time-keeping electronic circuit (12) for driving the motor (9) - for temporarily further driving the motor (9), so that the pointer toggle (4) is moved into its defined quiescent position (11) via a friction connection (10), while ensuring that the bending spring makes contact. In order nevertheless to construct a complete circular time circuit (5) for presetting a one-hour short time and in order thus to be able to use a standard clockwork drive for the drive train between the motor (9) and the pointer toggle (4), the pointer toggle (4) runs in its quiescent position (11) against a variable-position stop (57). <IMAGE>

Title: Optical advertising device having a light-transmitting mirror
Inventor: GREIFF THOMAS H
IPC: G09F13/12
Filed: 1982-11-16
Abstract: In an optical advertising device having a light-transmitting mirror behind which is mounted a transparency which carries the advertising information and is illuminated at time intervals by a light source arranged behind it, the light-transmitting mirror forming the front closure, facing the observer, of a housing which accommodates the transparency and light source, the object of reducing the depth dimensions of the device to dimensions such as are adopted in normal framed mirrors, a sharp image being produced on the semi-transmitting mirror given full illumination of the transparency, is achieved when the transparency is a large-format transparency which bears directly against the silvered rear of the light-transmitting mirror and is pressed by a light-transmitting pressure disc against the mirror, and when the light source consists of at least one fluorescent tube or grouping of fluorescent tubes which emit diffuse light, and positively illuminate the entire transparency uniformly, and are arranged behind the pressure disc. All the switch gear and the chokes of the fluorescent tubes are accommodated in a separate switch gear chamber of the housing which is situated outside the mirror region. The time intervals of the illumination of the transparency and/or the duration of the illumination can, as the case may be, also be adjusted to different periodic cycles.

Title: Secondary gas jet compressor installation for gas turbines
Inventor: DENS HORST
IPC: F02C3/32
Filed: 1983-02-16
Abstract: The secondary gas jet compressor installation serves for the delivery and heating of working gas for the operation of a gas turbine. In this arrangement, gas from a high-pressure and high-temperature producer is used as driving gas for a secondary gas jet compressor. The air delivered by this secondary gas jet compressor has fuel added to it which serves to increase its energy. In order to increase the air delivery rate, a plurality of secondary gas jet compressors can be connected in series and the high pressure of the first secondary gas jet compressor thereby lowered in stages to the operating pressure of the turbine. The fact that the energy of the driving gas is transferred to the fuel/air mixture to be delivered not only mechanically but also chemically by the formation of molecules contributes to the improvement in the efficiency of the secondary gas jet compressor installation.

Patent DE-3318974-A1 (DE)
Title: Flame detector
Inventor: SCHIERAU KLAUS DIPL ING
IPC: G08B17/12
Filed: 1983-05-25
Abstract: In a flame detector having a first opto-electric transducer (T1) whose relative sensitivity has an extreme value in the visible to the near infrared wavelength region, and a signal conditioning circuit downstream of the transducer, a second opto-electric transducer (T2) whose relative sensitivity has an extreme value in the visible to near infrared wavelength region and at least one extreme value in the ultraviolet wavelength region is connected in parallel with the first transducer (T1) but, relative to the photocurrent flowing through the transducers (T1, T2), in opposition with the first transducer (T1) to the input of the signal-conditioning circuit (S1), so that the signals generated by the transducers (T1, T2) compensate one another in the visible to near infrared wavelength region. A pyroelectric sensor (T3) can be connected for the infrared wavelength region to the signal-conditioning circuit (S1).
Patent DE-3320730-A1 (DE)
Title: Temperature monitor
Inventor: ROLLER HANNO
IPC: H01H1/50
Filed: 1983-06-09
Abstract: Temperature monitors (1) limit the temperature of electrical apparatuses by automatically opening the circuit, and are not intended to reset themselves again until a significant temperature change has occurred. In this case, if a load (9) overheats, the contact (5') which is mounted on the bimetallic strip (5) lifts off the mating contact (4) into an open position, as a result of which the current flow through the contact arrangement is interrupted. In the event of defect sources not being rectified, frequent switching, so-called "controller chattering" results in the risk of the contacts of the temperature monitor welding. In order to prevent switching on again, it is thus provided that the contact arrangement be bridged by the PTC thermistor (6) when it is in the open position. The open position is maintained until the load (9) is disconnected by hand. <IMAGE>

Title: Process and system for regenerating digital data
Inventor: THOMPSON CHARLES ROBERT
IPC: G11B20/10
Filed: 1983-06-21
Abstract: For regenerating in the NRZ-I format digital data which have, for example, been played by a digital video-tape recorder (10), the data are integrated by an integrator (16) and differentiated by a differentiator (18). The integrated and differentiated data are in each case limited by a limiter (26 and 20, respectively), in order to obtain signals which reproduce exactly the zero crossings of the NRZ-I data. The differentiated and limited data are passed through a gate circuit (24) which is gated according to the zero crossings of the integrated and limited data. <IMAGE>
Patent DE-3326608-A1 (DE)
Title: Method for manufacturing a bridge train and single-span girders for implementing the method
Inventor: RIEDMANN EBERHARD
IPC: E01D21/06
Filed: 1983-07-23
Abstract: In a method for manufacturing a bridge train made of single-span girders according to the timed shifting method, a projecting console on the end of one girder engages during shifting in a support pocket on the end of the neighbouring girder. Underneath support pocket and console, the girder ends are clamped to one another by clamping members, pressure pieces being arranged between the girder ends in the region of these clamping members. The moments and forces occurring during shifting of the girders are absorbed by these means and transferred. If the girders are situated on their supports, then the concrete console is separated from one girder, as a result of which it is brought about that vertical forces which act on one girder are not transferred to the other girder. The transfer of horizontal forces is, however, ensured by the clamping members and the pressure pieces arranged between the girder ends, if such a transfer is required. The clamping members are then designed in a corrosionproof manner and arranged exchangeably.
Patent DE-3329618-A1 (DE)
Title: Cassette container
Inventor: RICHTER HERBERT
IPC: G11B23/023
Filed: 1983-08-17
Abstract: The locking means of the drawer in the housing is difficult, or at least laborious, to operate. In addition, the locking mechanism is complex to produce. A further objection is that the cassettes rattle in their containers, which becomes disturbingly evident in particular when such cassette containers are fitted in vehicles. According to the invention, a locking means is proposed which comprises a cam which can engage in a corresponding depression by a slight pivoting motion of the drawer and can consequently lock the drawer. This locking means is not only extremely simple to produce and completely maintenance-free, but requires no laborious manipulations either for locking or for unlocking. In addition, freedom from rattling is achieved to a great extent by the fact that a step on the stub engaging the tape hubs has the effect of fixing the housing as well and that in the bottom of the drawer there is provided an opening, which engages a thickening of the cassette and at the same time makes it possible for the surface of the cassette to bear fully against the bottom of the drawer. <IMAGE>
Patent DE-3332972-A1 (DE)
Title: Heel hold-down
Inventor: BAUER HELMUT
IPC: A63C9/084
Filed: 1983-09-12
Abstract: The invention relates to a heel hold-down of a ski binding, having a guide plate which is guided on a guide rail and on which a bearing block is arranged. On the inside of a transverse wall of the bearing block, the latter bears engagement cams. Supported in its side walls is an axle on which a spring housing and a sole hold-down with a tread bar are mounted. Arranged on the axle is a leg spring which forces the said parts into the upper position. A control part and a release lever are linked to the binding housing. According to the invention, this heel holder is to be constructed in such a way that it is simple in construction and reliable in its function and has a large range of elasticity and little putting-on force. This object is achieved according to the invention in that the control part and the release lever are guided on a common axle in curved slots in the bearing block, and the release lever bears a bolt which passes through an elongate hole in an extension of the spring housing.

Title: Method for electronically transmitting several images on one transmission channel
Inventor: WOLF PAUL
IPC: H04N7/08
Filed: 1984-01-19
Abstract: In this method for electronically transmitting several images, present at the same time, on a transmission channel 23 from a transmitter to a receiver, the images are scanned line by line and preselectable image areas are suppressed during the transmission. To be able to utilise the transmission capacity of the individual transmission channel as optimally as possible, omitting non-relevant image areas in the transmission, relevant image areas A, B to be transmitted, in each case comprising several successive lines, are selected in the individual images at the transmitter end in such a manner that the sum of the heights of these image areas amounts at most to the height of the total image. Furthermore, the individual images are scanned with phase shifts dependent on the position and height of the respective relevant image areas and the scanning signal sequences are supplied to the inputs of a multiplexer 8. This in each case switches through to the transmission channel 23 the input 10 or 12 at which the signal sequence corresponding to the associated relevant image area is present at the time. At the receiving end, a corresponding demultiplexer is provided. <IMAGE>

Title: Rolling contact bearing with resistance to rotation as a function of the angle of rotation
IPC: B61F5/16
Filed: 1984-01-26
Abstract: The invention relates to a rolling contact bearing consisting of two races (1) and (2), rolling elements (3) which roll between the latter, and a braking device which influences the resistance to rotation of the rolling contact bearing as a function of the angle of rotation and consists of a brake shoe (4) which is rotationally connected to one of the races (1) and rests against a mating surface (8), rotationally connected to the other race (2), under the action of a contact pressure. In order to simplify the structure of the braking device as much as possible and thus enable the rolling contact bearing to be manufactured at a favourable cost without limiting its reliability by the use of external means for actuating it, the contact pressure is made constant and the mating surface (8) has sections with different coefficients of friction extending in the circumferential direction. <IMAGE>

Title: Headrest for motor vehicle seats
Inventor: BUTZ EUGEN OTTO
IPC: B60N2/70
Filed: 1984-04-10
Abstract: A headrest for motor vehicle seats has a support frame which is enclosed by a frame-shaped or annular foamed upholstered element. The support frame constitutes an inverted U-shaped bar whose ends form, outside the foamed upholstered body, the insertion ends held in the seat backrest. The insertion ends are connected to one another inside the foamed upholstered body, if appropriate via a lower transverse web. The foamed upholstered body receives the support frame in a locking snap-in fashion in a demoulded cavity. In the region of its larger cross-sectional width, the demoulded cavity lies with its inner face over a predominantly circumferential length of the support frame profile against the said profile. The demoulded cavity has a cross-sectional area which narrows outwardly with pliant junctions in a droplet or gusset-shape, the said area being continued in a demoulded joint or fitting joint. The demoulded joint or fitting joint opens outwardly and follows the contour of the support frame over the entire length.
Patent DE-3417038-A1 (DE)
Title: Pump/motor unit
Inventor: KRAEMER ROLAND DR
IPC: F04D29/10
Filed: 1984-05-09
Abstract: A pump/motor unit (1) (Figure 2) is designed as a canned motor pump and is used especially for delivering highly compressed gases or gas-laden liquids. To prevent gas particles from reaching the area of the motor and particularly the area of the journals, at least one hydrodynamic seal (18) is provided. This isolator stage is formed in the rear region of the pump impeller (4) with the aid of an intermediate impeller (19). In order to remove the waste heat of the motor, and also in order to lubricate the journals, a separate fluid circulation having a heat exchanger (20) is connected. If required, yet another isolator in the area of the pump impeller can be provided by means of a fluid seal circulating in a recess (9) of the pump impeller (8). Via bores (15) and (38), the motor circulation can be continuously resupplied with fluid, in order to replace any leakages as a result of gas/liquid return via the tubular shaft (24) or the duct (35). Centrifugal force then causes the separation of gas and liquid, and as a result essentially only liquid collects in the recess. <IMAGE>
