Title: Triple belt driver
Inventor: WALLICH ERICH
IPC: G01M3/02
Filed: 1981-10-20
Abstract: Pipes and bars, in particular those which have widened portions at the ends, are fed to a material-testing device or other testing device and are moved out of it again via an apparatus which has rollers arranged one behind the other in pairs and connected by a driving belt to a cushion which is flexible to a limited extent and bears on the outside. The cushion of the driving belt catches the widened portions so that the apparatus, designated as driver, does not need to open.

Title: Process for heating a heat carrier by means of a hydride heat pump
Inventor: JAKOB FRITZ
IPC: C01B3/00
Filed: 1981-11-12
Abstract: The invention relates to a process and equipment for heating a heat carrier by means of a hydride heat pump, hydrogen being desorbed from a first hydride store at low pressure by supplying heat at a low temperature level, being transported to a second hydride store and being absorbed by the latter at high pressure, and the heat of formation thus released at a high temperature level being transferred to the heat carrier. Known processes required hydride systems consisting of various metals or metal alloys. This causes difficulties in the selection and matching of these various hydride systems. In order to enable heat to be brought to a high temperature level in a simple and reliable manner by means of a hydride heat pump, it is proposed to compress the desorbed hydrogen in a compressor to the high pressure and to feed it to the second hydride store. <IMAGE>

Title: Method for controlling the DC current or the DC voltage of a converter
Inventor: FRANKENBERG WOLFGANG DIPL ING
IPC: H02M7/162
Filed: 1981-11-16
Abstract: In subsynchronous converter cascades or DC conveying machines, the difficulty occurs that the maximum operating current in the DC circuit must be controlled in a DC circuit with a minimal DC voltage on the DC side of a converter which is located between the DC circuit and a three-phase network. To this end, the converter, which is constructed as a three-phase bridge, is operated with main control pulses which control the converter valves by means of main control pulses (main delay angle  alpha ), as in the case of normal rectifier or invertor operation. In addition, a freewheeling control pulse is emitted in each case between two main control pulses, by means of which freewheeling control pulse the other bridge-arm half of the bridge arm which is driven by the last emitted main control pulse is switched on. This produces a freewheeling path for the DC current which flows on with few harmonics while the three-phase network is temporarily decoupled from the DC current and is loaded only with a small amount of reactive power. <IMAGE>

Title: Pressure-measuring device
Inventor: MEYER WOLFGANG DR
IPC: G01L11/02
Filed: 1982-03-31
Abstract: The fibre-optic pressure-measuring device measures two different pressures, e.g. of explosive gases or liquids. For differential pressure measurements, the optical fibres of two fibre-optic sensors having a common base body (7) and two diaphragm-like sensor faces (11, 12) that can be moved with respect to the base body (7) can be deformed mechanically as a function of pressure in such a way that the light fed into the fibre from a common light source at one end is scattered by the deformation. The amount of light emerging at the other end is measured by two detectors (23, 24). The different magnitudes of the signals of the detectors produce a measure of the pressure difference in the chambers (3 and 4) in an evaluation circuit (27). <IMAGE>

Title: Conveying arrangement for connecting a production machine for cigarettes to a packaging machine
Inventor: BAESE HORST DR ING
IPC: A24C5/35
Filed: 1982-04-15
Abstract: The invention relates to a conveying arrangement for connecting a production machine (FA) for rod-shaped articles in the tobacco processing industry, especially cigarettes, to a further processing machine (PM), especially a packaging machine. In this arrangement, the articles are conveyed in a multi-layer flow along a conveying path (FS) from the production machine to the packaging machine. If for any reason the production rate exceeds the further processing rate, e.g. as a result of a fault in the packaging machine, the articles are automatically removed from the conveying arrangement, e.g. by an oblique filler (SD). If, on the contrary, the further processing rate exceeds the production rate, for example as a result of a fault in the production machine, articles are transferred from a feed device, e.g. by a magazine filler (MF), onto the conveying path (FS). The feed device is situated downstream of the removal device (based on the conveying direction of the conveying path). <IMAGE>

Patent DE-3223266-A1 (DE)
Title: Scattering device for arrangement on a vehicle
Inventor: PETERSEN JENS
IPC: E01C19/20
Filed: 1982-06-22
Abstract: A scattering device for arrangement on a vehicle and with a container (1), from which the material to be scattered is delivered via a dosing device and a running wheel (3) arranged at the rearmost end of the vehicle. The running wheel can be lowered for contact with the roadway and is arranged for driving the dosing device and possibly also a scattering disc (2) by means of an energy-transmitting device. The energy transfer is brought about by a hydraulic wheel pump (4) which is connected to the wheel (3) and which, via a pressure line, delivers pressure fluid to one or more hydraulic motors (11) which drive a number of agitating and delivery rollers. According to the invention, the pressure fluid is also conducted to a piston (12) in a cylinder which - when the pressure in the pressure line has fallen to a given value, when there is no material in the container or when the scattering is disconnected - causes the wheel no longer to be pressed against the roadway. As a result, unnecessary drawing of the machines is avoided when the material container is empty or when the scattering is disconnected. <IMAGE>
