Patent DE-3813216-A1 (DE)
Title: Device for influencing the thread tension in a thread-processing textile machine, in particular knitting machine
Inventor: MEMMINGER GUSTAV
IPC: D04B9/52
Filed: 1988-04-20
Abstract: A device for controlling the thread tension in a thread-processing textile machine, in particular a knitting machine, has at least one controllable thread-tensioning device, which influences at least one thread, and an electronic control circuit which controls said device. The control circuit receives input signals which are derived from the textile machine via a signal input and characterise its operating sequence and generates control signals for the thread-tensioning device, which control signals it passes on to said thread-tensioning device via at least one signal output. Additionally, the control circuit is designed to have a freely programmable programming device, by means of which the control signals are automatically variable in accordance with a predetermined, temporal programme sequence.
Patent DE-3814353-A1 (DE)
Inventor: BAAS DIETER
IPC: G04G13/02
Filed: 1988-04-28
Abstract: Electric alarm clocks such as, e.g, radio alarm clocks, awake the sleeper with the volume last set. However, because on the one hand the volume must be high enough in order to prevent the risk of oversleeping while, on the other hand, sudden awakening owing to noises which are too loud damages the human nervous system and psyche, it is difficult to set the optimum volume. Because, furthermore, the sensitivity of hearing and the depth of sleep fluctuate from day to day, it is never known in advance precisely what volume is optimum for waking. In order to achieve reliable and yet soft awakening, the volume rises from a presettable initial value to a presettable final value. It is particularly advantageous if it is also possible to set the time in which the volume rises from the initial value to the final value. It is determined in this way whether waking is more or less soft. Radio alarm clocks with and without cassette component, hi-fi installations with tuner, cassette component and CD player.

Title: Clamping device for the belts of motor vehicle safety belt systems
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/18
Filed: 1988-05-20
Abstract: The clamping device has at least two clamping elements which can be adjusted in opposite directions so as to come to rest against the belt (2), and in particular a clamping wedge (4) which can be displaced in a casing (3) and a clamping wall (8) which is constructed on the casing (3). The clamping elements, i.e. the clamping wedge (4) and the clamping wall (8) are coated with a sliding layer, especially a thin and hard sliding layer, at the points (9, 15) in contact with the belt (2). If the or every movable clamping element is displaceable in a sliding manner, the corresponding sliding surfaces must then be coated with a sliding layer of this type, i.e. in the case of the clamping wedge (4) the sliding surface (16) of the latter and the associated sliding surface (14) of the casing (3). The clamping device is designed to be as rigid as possible, an adjustment path which is as short as possible being provided for the and/or every movable clamping element and/or the clamping wedge (4) and the latter being provided with as small a mass as possible. The clamping device is especially well suited for installation in a self-locking belt retractor (1) and ensures that the belt (2) is clamped tightly as gently and as rapidly as possible, the belt being extended by an appropriately small amount. <IMAGE>

Title: Cutter blades for rotary mowers for the possibility of use on four sides
Inventor: SCHNEIDER ALOIS
IPC: A01D34/73
Filed: 1988-11-12
Abstract: Cutter blades for rotary mowers have two suspension holes for changing them. In order to achieve the safety of a conventional blade of 10 mm behind the suspension hole and a 20 mm wearing part, there is an extension of 10 mm on both sides of the blade and an equivalent shift of the suspension hole towards the opposite side. The dimensions of the conventional blade and also the projecting length of 30 mm from the edge of the rotary plate are thereby achieved.

Title: Housing for a hot-air heating system with air filter
Inventor: GOSSENS HEINZ
IPC: F24D5/00
Filed: 1988-11-23
Abstract: In the case of the conducting housing for air-conditioning and/or heating-system air, the air filters must be maintained at preset intervals, i.e. replaced. In this respect, until now there has been the problem that, when pulling out the holders for the filter means, which holders are in most cases of frame-like design, dust falls into the conducting housing due to the vibrations and, upon restart, is then discharged into the spaces to be aerated. In order to avoid this, the holder (18) fitted with the filter means (9) is designed so that it can be folded up about a transverse axis (8). For replacement of the frame-like holder (18), it is folded up so that the dust-covered filter faces lie on top of one another, the bag-like structure thus obtained allowing virtually no dust to fall into the flow duct itself. <IMAGE>

Patent DE-3933585-A1 (DE)
Inventor: DOERR KLAUS PROF DR ING
IPC: B62D7/15
Filed: 1989-10-07
Abstract: The object of the invention is a parking and manoeuvring aid for wheeled motor vehicles with one or more steerable driving wheels (1-4). Where necessary, especially when entering and leaving parking spaces, it provides special parking facilities for highly flexible and easy manoeuvring in extremely tight spaces, including lateral parallel movements, rotary movements on the spot or swinging movements for the front of the motor vehicle. The invention makes this possible without any special parking devices on the drive system, with normally tyred wheels in a normal layout, essentially by drive shifts in the differential gearing. To this end: in vehicles with four-wheel drive, the front (1, 2) and rear axle (3, 4) or the right-hand wheels (1, 4) and left-hand wheels (2, 3) and in front-wheel drive vehicles, only the right and left-hand front wheels are driven at the same time, possibly on alternate sides, in opposite directions of rotation. Thereby the tractive power components (Fx) along the vehicle's longitudinal axis are compensated and the tractive force components (Fy) are added together or form highly axial torques (M) and thus ensure the appropriate vehicle movements. Steering angles are preferably produced by servomotor longitudinal displacement of the track rod, possibly opposite steering angles for right-hand and left-hand driving wheels, to ensure the tangential rolling of the wheels on a circular path.

IPC: F24S23/30
Filed: 1989-10-17
Abstract: The solar rays are focussed onto a receptor line. The disc shaped concentrators are formed from rows of facets, extending parallel to the receptor line. The vertical intersection planes in parallel to the receptor line form a continuous angle with the receptor surface. In the orthogonally extending intersection planes they form another angle with the surface. The intersection planes are reduced down to 0 deg. from the edge to the vertical plane, contg. the receptor line. Pref. the undersides of the facet are reflectively mirrored. The concentrators are typically made integrally of pressed glass. ADVANTAGE - Steeper impingement of diffracted or reflected rays onto the receptor.

Title: Collision warning system for vehicle - evaluates transmitted HF signal modulated with information representative of vehicle speed and acceleration
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: G08G1/16
Filed: 1989-12-15
Abstract: The warning system operates on the premise that all vehicles (1.2) are equipped with a forward looking Rx (E) and rearward directed Tx (S). The Tx (S) transmits an HF signal (S2) modulated with information representative of vehicle speed and acceleration. The vehicle receives, simultaneously, any transmitted signal (S1) containing similar information from a vehicle (1) travelling in front. The warning system comparator unit compares and evaluates the vehicles Tc signal (S2) with the received signal (S1), taking into account pre-programmed information such driver reaction time, weather conditions and vehicle handling characteristics. Should any danger of a collision be imminent the vehicle driver is alerted by a visual and/or audible signal. USE/ADVANTAGE - Cheap and reliable warning system. Improved performance and effectiveness in tight curves - Tx signal strength which is inversely proportional to vehicle speed automatically adjusts effective Tx range.
