Title: Ground weapon selective detonation system - counts amplitude variations of sensor signal via counter coupled to programmed evaluation logic
Inventor: SPIES HANS
IPC: F42C13/00
Filed: 1980-03-25
Abstract: The system uses a sensor coupled via an amplifier and a rectifier to an integration stage. The amplitude of the sensor signal and its waveform is monitored with the amplitude variations being counted and used to initiate detonation. Pref. the integration stage provides periodic rectangular signals from the sensor signal fed to a storage and comparator stage and to a threshold evaluation stage, so that a counter can be indexed each time the output signal exceeds a given threshold value and fed to an evaluation logic for initiating detonation. Pref. the evaluation logic can be externally programmed and the system is reset immediately or after a given interval when the signal drops below a min. threshold value. The detonation system allows the shell to be detonated by the ground vibrations caused by the target object, e.g. a tank, but prevents detonation by other causes.

Title: Tape measure with stitch number indicator
Inventor: EBERSPAECHER GEB HELMS
IPC: D04B3/00
Filed: 1981-03-06
Abstract: The patent application relates to the hand-knitting of woollen yarns and removes difficulties in such work in that missing, but required information on the packaging strips surrounding the balls of wool is determined by the invention. It is noted on the packaging strips that a particular thickness of knitting needle must be used for the quality of the wool and that a corresponding number of stitches is required for a length of 10 cm. Difficulties occur due to the fact that the number of stitches for the length of the item to be knitted has to be converted from the specified 10 cm to the required length. This conversion not only poses difficulties for elderly women, it also leads to miscalculations since decimal points have to be included in the calculation if, for example, the required length is 53.5 cm. These difficulties are eliminated by the invention in that the required number of stitches corresponding to the thickness of knitting needles used can immediately be read off on the tape measure, which is required for measuring the required length of the item to be knitted, in addition to the measured size.
Patent DE-3120553-A1 (DE)
Title: Pedal cycle
Inventor: HOFGAERTNER KURT
IPC: B62M11/10
Filed: 1981-05-22
Abstract: In the case of a pedal cycle with bevel-gear drive, particular problems arise if the hub (7) of the rear wheel is intended to be spring-loaded and, for this purpose, is intended to be movably mounted on a swinging fork (6). Spring-mounting of the rear wheel in this manner in a pedal cycle with bevel-gear drive can be achieved in an operationally reliable manner with only minimum additional expense if at least one section of a swinging-fork arm (6a) is formed by an in particular tubular bearing housing (22) for the drive shaft (15) of the gear mechanism, and the swinging fork (6) is held such that it can swivel around the bottom-bracket bearing spindle (4). As a result, when spring movements of the hub (7) occur, no changes in the toothed engagement between a drive wheel (11) on the bottom-bracket bearing (4) and the input pinion (14) of the deflection gear mechanism take place, whereas the overlying oscillation movement which occurs is of too low amplitude and frequency to cause a disturbance. The drive pinion (19) seated on the hub (7) of the rear wheel can be fastened in the manner known for the conventional sprockets, so that no particular structural adaptations of the hub (7) to the bevel-gear drive are required. The hub (7) of the rear wheel is connected in a tension-resistant manner to the pedal crank (4) via the swinging fork (6) by one or two swinging-fork arms (6a, 6b), so that the rear wheel is guided in an unobstructed manner. <IMAGE>

Title: Diaphragm for electroacoustic transducer systems
Inventor: STUTE MARTIN
IPC: H04R9/04
Filed: 1981-06-11
Abstract: The invention relates to diaphragms with predominantly resistance braking for electroacoustic transducer systems which have a high degree of pulse accuracy during the signal conversion and are therefore particularly suitable for faithful reproduction of music and speech signals. The previously known transducer systems having predominantly resistance braking exhibit considerable inadequacies with respect to the sound pressure level which can be radiated undistorted and a radiation which is strongly focused in the direction of the axis of symmetry in the high-frequency range of music. These defects have their cause in the design of the diaphragm as an annularly driven plate which is exclusively characterised by damped flexural vibrations. In the transducer systems according to the invention, the diaphragm consists of two functionally different components, a central inner part-area (1) vibrating in the form of a piston being provided, on the one hand, and an outer part-area (2) excited into damped flexural vibrations by the inner part-area (1) being radially arranged, on the other hand, so that the abovementioned inadequacies do not occur. Figure 1 shows a transducer system with the two diaphragm part-areas (1; 2) according to the invention, in which the inner part-area (1), in particular, can have a greater thickness of material than shown in a practical embodiment.   <IMAGE>
