Patent DE-3331519-A1 (DE)
Title: Method and device for correcting the measurement of the flow velocity of fluids by means of ultrasound
Inventor: BECKER WOLF-JUERGEN DR
IPC: G01P5/24
Filed: 1983-09-01
Abstract: In order to measure the flow velocity (v) of fluids (2) by means of ultrasound, in which at least one ultrasonic measurement section in the fluid is transirradiated by two ultrasonic transducers (4, 5) in the forward and reverse directions (6, 7), it is conventional to make use of the difference in the transit times or the difference in the repetition rates as reciprocals of the transit times. However, the result in this case is that because of the dead times in the dead spaces upstream of the ultrasonic transducers (4, 5), the instantaneous sound velocity (v) in the fluid (2) influences the measurement result owing to the response delay of the ultrasonic transducers (4, 5) themselves and to response delays in the measurement electronics. This influence can be compensated with the aid of the sum of the transit times or of the sum of the repetition rates as reciprocals of the transit times. <IMAGE>

Title: Infrared remote control system for an electric appliance, in particular a TV receiver
Inventor: SCHUETZE HERBERT ING GRAD
IPC: G08C23/04
Filed: 1983-10-13
Abstract: In an infrared remote control system, in particular for a TV receiver, in which a digital remote control signal is modulated onto a carrier, the frequency of the carrier, which has previously been approximately 35 kHz, is increased to at least a few 100 kHz, in particular 500 kHz. As a result, the system becomes noise-immune, in particular with respect to consumers, e.g. fluorescent lamps, which operate by means of switched-mode power supplies.
Patent DE-3337445-A1 (DE)
Title: Loading monitor with moment-capacity limiter for use in a hydraulic circuit
Inventor: BOUTON BERNARD
IPC: B66C23/90
Filed: 1983-10-14
Abstract: The invention relates to a loading-monitor and safety device for a hydraulic circuit for controlling, for example, the movements of a crane (7) on the loading surface (1) of a motor vehicle. 
<??>Pressure switches (23, 24) are set to different response pressures but both are connected in parallel to the working chamber (20) of large cross-section of the power cylinder (18) of the jib (12). A programmed, electronic arithmetic unit (26) receives the signals from the pressure switches (23, 24) to permit or block the movements selected by the operator when the operator actuates the hydraulic control levers (32). The arithmetic unit (26) can block a movement by actuating a hydraulic solenoid valve (29). 
<??>Use: blocking the dangerous movements of the crane (7), which could, for example, otherwise cause the lorry to overturn.

Title: Securing of sheets or loose pages in book covers or files
Inventor: MUELLER WALTRAUD
IPC: B42F13/00
Filed: 1983-10-31
Abstract: The invention consists in simplifying the relatively expensive binding of books by attaching loose sheets on metal clasps. The clasps are of flat design, take up little space and have an optimum shape. The clasps are secured on the inside of the book cover. The sheets to be inserted are preperforated to fit the clasps. After insertion of the sheets, the clasps are pressed closed so that the sheets are bound in the manner of a book. In the attached drawing, a book cover with an open clasp (1) (for inserting the sheets) can be seen in Figure 1 and with a closed clasp in Figure 2. The binding of these books can take place far more quickly than in the conventional type of book-binding. Additionally, the work can be carried out by unskilled employees. This type of book-binding is particularly suitable for books for the blind since the sheets lie flatter when opened out and better reading up to the middle of the book is possible. <IMAGE>

Title: Circuit arrangement for telecommunications systems, in particular telephone switching systems, with information-inquiry devices cyclically activating polling stations
Inventor: ZILBAUER WERNER DIPL ING
IPC: H04Q3/545
Filed: 1984-11-29
Abstract: A polling device cyclically retrieving information from different polling stations activates the different polling stations with different regularity. Polling stations assigned to a plurality of cycle classes are activated on each first to nth cycle depending on the class. If a polling station has provided an item of information, it is immediately re-activated in the next cycle and again thereafter according to the assigned cycle class. At time intervals in each case spanning a plurality of cycles, the information retrieved from each polling station is counted individually. Depending on this, the polling stations are assigned as required to the next highest or to a correspondingly lower class. <IMAGE>

Title: Sports and leisure vehicle for the, preferably motorless, rolling or sliding locomotion of an individual
Inventor: MAUERHOFF WOLFGANG
IPC: B62K5/05
Filed: 1985-02-21
Abstract: A sports or leisure vehicle for the, preferably motorless, rolling or sliding locomotion of an individual has a frame (10) in the form of an upright, three-legged stand whose one leg (12) which points upwards bears a saddle (72) and the other legs (14, 16), which point downwards, support rolling or sliding elements (18, 52), preferably such that they can be exchanged, on transverse axles (50, 24). The front transverse axle (50) can be tilted about a longitudinal axis (36) and can be pivoted about a third axis (46) and, when the vehicle tilts, is steered by control means (56, 58) in a direction opposed to the tilting direction. The control means are preferably formed by cams (58), on which control rollers (56), which can be tilted and pivoted with the transverse axle (50), move in rolling contact. A control element (80), which can be grasped by the hands, permits a pivoting of the cam (58) about the longitudinal axis (36). The sports or leisure vehicle according to the invention is cheap to manufacture and is small in size and can be used, in particular, as a practice vehicle for learning how to ride a unicycle or as a ski-bob. <IMAGE>

Title: Method and device for producing wire sections of predetermined length and contour
Inventor: JUNG HERBERT
IPC: B21F45/24
Filed: 1985-03-21
Abstract: Wire sections of predetermined length and contour must be provided for the wiring of components, especially of ceramic capacitors. Until now, wire sections have been cut from a wire roll and formed serially, for this purpose. The wire sections are intended to be provided as a stack, for which purpose a continuous endless wire is wound in one layer around a peg, and the wire winding is subsequently cut off. According to the invention, the winding and cutting off of wire take place continuously in a continuous-flow process. For this purpose, in the case of an automatic winding device for winding around strips as winding pegs, the individual strips (55, 65, 75, 85, 95) are constructed for jointless adaptation, and an automatic winding device (100) has a guide channel (101) for passing the adapted strips (55, 65, 75, 85, 95) through. <IMAGE>

Title: Electrical snap-action switch
Inventor: MENCHE EDGAR
IPC: H01H13/36
Filed: 1985-05-02
Abstract: An electrical snap-action switch which builds on the subject-matter of Patent 3, 436, 967 is proposed. This electrical snap-action switch, which is composed essentially of a box-shaped housing (which is preferably manufactured from plastic), stationary contact parts which are held therein, a snap-action switching element (which is allocated to the stationary contact parts and can be influenced via an operating element), a switching rocker (which is allocated to the operating element and is supported on a stationary contact part) and an intermediate piece (which is supported on the switching rocker and on the snap-action switching element) is subject to the technical problem of refining said switch in such a way that the snap-action switching element continuously exerts such a force on the operating element that the resetting of the operating element is ensured without any additional spring force. This is implemented in that the intermediate piece, which is held in a moving manner and engages on the one hand with the other narrow side of the snap-action switching element, is on the other hand allocated to a switching rocker whose one end is connected to the operating element and whose other end is supported in a moving manner on the one stationary contact part.
