Patent DE-3300228-A1 (DE)
Title: Powder-conveying device for an apparatus for coating articles with wear-resistant coatings
Inventor: ANDERSEN DENNIS
IPC: B05B7/14
Filed: 1983-01-05
Abstract: A powder-conveying device (20) has a container (22) with a powder chamber (28) which is bounded by one upper and one lower porous diaphragm (40, 38). The diaphragms (38,40) are permeable to gas but not to powder. Gas under pressure is directed upwards through the lower diaphragm (38), in order to suspend powder particles of a desired size at the level of a delivery pipe (44), the inlet opening (46) of which is connected to the powder chamber (28) between the diaphragms (38,40). The gas flows through the powder chamber (28) in the form of a vortex, in order to propel particles by the action of centrifugal force towards a side wall of the powder chamber (28) at which the particles fall to the lower diaphragm (38) under the force of gravity. Powder collecting on the lower diaphragm (38) is distributed anew by a multi-vane rotor (60) which simultaneously compresses the powder. The inner end of the delivery pipe (44) penetrates into the powder chamber (28) and extends upwards. The feed of gas under pressure to the lower diaphragm (38) takes place out of a gas inlet chamber (27) which is beneath the diaphragm (38) and whose side wall (72) can be heated by heating elements (120) in order to dehumidify the gas before it reaches the powder chamber (28). <IMAGE>

Patent DE-3313623-A1 (DE)
Title: Control for hydraulic drives
Inventor: ERTLER WERNER
IPC: G05B19/23
Filed: 1983-04-12
Abstract: Control for hydraulic drives having hydraulic cylinders which are actuated by means of a proportional valve and having a volume sensor which emits electric pulses for discrete amounts of oil. The pulses are passed to a pulse counter, which is preloaded with a number of pulses corresponding to the displacement. The pulse counter operates in a decrementing manner and sends pulses to a D/A converter, provided with an analog amplifier. By overdriving the D/A converter, the steepness of the characteristic curve is set for a given number of pulses. The output of the analog amplifier is connected to a comparator, to which furthermore a voltage determining the set speed is applied via a means of control for the acceleration ramp. The two inputs of the comparator are connected to the two inputs of a changeover switch, the outputs of which are connected via an amplifier to the electromagnet of the proportional valve. If the voltage is the same, the comparator switches the changeover switch from the speed set-value circuit to the output of the D/A converter. The characteristic curve of the D/A converter forms the deceleration ramp from the intersection with the speed set-value voltage. The drive is shut down by a pulse in the counter position zero. <IMAGE>

Patent DE-3327628-A1 (DE)
Title: Shunting vehicle
Inventor: KOTAI FERENC DIPL ING
IPC: B64F1/22
Filed: 1983-07-30
Abstract: In order to couple the nose undercarriage of even very large transport aircraft to a shunting vehicle without damage, a lifting and locking device is proposed, which is provided in the region of the fork-shaped end of the vehicle chassis and has tongs which can be operated hydraulically for each wheel of the nose undercarriage. The tongs lever, which can be pivoted in a vertical plane, supports a roller block on its lower section, which roller block can be folded up in the region between the side limbs of the fork-shaped chassis end by rotating the lower tongs lever section with respect to an upper tongs lever section, and can be folded out from this region. In this way, the wheels of the nose undercarriage can be positioned in the fork-shaped region without hindrance. Once the wheels have been positioned, the folded-in roller block is moved against the running surface of the associated wheel, as a result of which the wheel is clamped in between this roller block and two further roller blocks, which act as counter-bearings for the tongs. On further feeding, the rollers of the roller blocks at the bottom push under the relevant wheel and lift this up, as a result of which the force-fit and positive-lock between the nose undercarriage and the shunting vehicle is produced. <IMAGE>

Title: Process in a telephone system for the connection of mobile subscriber terminals
Inventor: KUENZEL ROLAND DIPL ING
IPC: H04W88/02
Filed: 1983-08-12
Abstract: The invention relates to a process in a telephone system for the connection of mobile subscriber terminals which can be reached by radio-paging and in which a call-back requirement can be stored by means of a permanent subscriber station. The object of the invention is to make the call-back procedure particularly user-friendly. This is achieved by storing in the memory of the mobile subscriber terminal not only the requirement for call-back but also the address of the person requiring the call-back. At a permanent station, after dialling an identification code, the mobile subscriber can give through the stored address at voice frequency by holding his station against the receiver of the permanent station and consequently initiate direct dialling to establish a connection. The subscriber can also enter as a fixed input at the mobile station itself an address by which he can, for example, reach a "mailbox address". With the process according to the invention, a simple operating procedure is possible.

Title: Device for producing a force which is opposed to a tilting force acting on the device
Inventor: HAKEMANN FRITZ
IPC: B66C23/74
Filed: 1983-12-24
Abstract: During pivoting of its running axis, a gyroscope attempts to escape in a movement offset at right angles to the direction of the pivoting force. A torque is consequently imparted to the frame in which the gyroscope is mounted, which torque attempts to rotate the frame about its rotational axis. This torque of the frame is utilised according to the invention in order to counteract a tilting moment via a suitable frictional connection, which tilting moment is directed into the supporting element. Gears, for example, are suitable as frictional connection. It is also possible to convert the torque of the frame into pressure by means of a hydraulic device with working cylinders and to utilise it.
