Title: Combined IC engine and electric motor drive for crane - uses flywheel to collect energy output from engine during crane load descent
Inventor: HAGER KLAUS DIPL ING
IPC: B66C13/22
Filed: 1980-12-23
Abstract: The floating crane uses an internal combustion engine driven generator to supply electric motors which perform the crane functions. When the crane load is descending the excess energy output by the engine is stored in a flywheel and is recovered when the generator is next loaded. The internal combustion engine can then operate at constant speed. The internal combustion engine drives both a 50Hz generator which supplies the crane auxiliaries and also the lifting generator which is coupled through a free wheel mechanism and gearing to a shaft carrying a flywheel. The three phase AC lifting generator is coupled to the flywheel, and generates a voltage which is passed to various electric motors through thyristor controllers. An auxiliary internal combustion engine drives a generator feeding a pony motor to start the main motor.

Title: Circuit arrangement for digitising and storing the maximum values of electrical ultrasonic pulses
Inventor: THUM HORST-GUENTER ING GRAD
IPC: G01N29/11
Filed: 1981-03-06
Abstract: A circuit arrangement for digitising and storing the maximum values of electrical pulses is described which is preferably used in ultrasonic test instruments for non-destructive testing of materials. The circuit arrangement (Figure 2) contains an analog/digital converter which operates in accordance with the parallel technique. In this technique, digitisation is effected with the aid of comparators (510) which are followed by D-type flip flops (530). The Q outputs of the D-type flip flops (530) are connected to the inputs of a priority encoder (540). To store the respective maximum value, the outputs of the D-type flip flops (530) are connected via OR gates (560) to the control inputs of the flip flops (530). The maximum binary value obtained at the output of the encoder (540) is transferred with the aid of an enable signal which is also generated by a logic combination of the outputs of the D-type flip flops (530) via AND gates (570). This enable signal is preferably used as a time reference value for a device measuring the delay time of ultrasonic pulses.
Patent DE-3110189-A1 (DE)
Inventor: CLEMENT CLAUDE M
IPC: G04C21/02
Filed: 1981-03-17
Abstract: The transducer is particularly useful in a watch. The emission of acoustic waves is caused by vibration of a thin diaphragm 8 occupying virtually the whole of the bottom of the watch case 1. The electromagnetic diaphragm excitation device 10 is disposed at an off-centre position. This not only makes it possible to operate with a small air gap, providing good electromagnetic coupling and therefore a good output, but it also makes it possible to produce a large vibration amplitude at the centre of the diaphragm 8 and therefore a high level of sound intensity for an entirely reasonable rate of consumption. The diaphragm 8 is fixed in a ring 6 which carries the excitation device 10 and which is fixed to the support frame structure 5 of the watch. This modular construction facilitates fitting and interchangeability of the electro-acoustic transducer. <IMAGE>

Title: Simple device for controlling the air gap in the magnetic circuit of a traction magnet to a freely predeterminable value
Inventor: BOEHRINGER ANDREAS PROF
IPC: B61B13/08
Filed: 1981-04-09
Abstract: The realisation of a free levitation state of relatively large bodies by means of electrically controllable traction magnets has acquired technical significance in particular for magnetic levitation railways. In Fig. 14, the movable armature (9) of a traction magnet is to bear the payload (7) in a freely levitating fashion. The levitation distance (12) of the armature from the core of the traction magnet is detected by means of a photoelectric barrier (15 and 16). In conventional arrangements, its output signal (Xact) influences a controller with differential component which suitably sets the exciter current of the traction magnet via a power amplifier (18). Deficiencies of such arrangements are inadequate stability and sensitivity to parameter changes and faults. The device according to the invention avoids these disadvantages. It forms a signal (Fact<*>) for the traction force of the magnet from the levitation distance and the magnet current by means of a function generator. The said signal serves as input signal of a linear observation system (43) for the speed of change of the levitation distance with which the levitation state is stabilised simply and without susceptibility to faults. Furthermore, with this traction force signal (Fact<*>), a subordinate traction force control circuit can also be realised and the system dynamics can thus be still further improved. <IMAGE>
