Patent DE-3029238-A1 (DE)
Title: Illumination installation for e.g. trees - has intermittently functioning light fittings whose flickering periods differ from each other
Inventor: TILLEN DIRK
IPC: F21S4/10
Filed: 1980-08-01
Abstract: The installation is particularly intended for Christmas trees in public places, gardens, parks etc. A number of electric light fittings are distributed over the trees etc. as decorative elements. The light fittings are of flickering type. However, the flickering sequences and periods of the individual light fittings are different and follow a random pattern. The individual light fittings preferably have a constant frequency, e.g. 0.5 to 3 Hz. Typically an electronic oscillation circuit is used for generating the flickering sequence pulses. Alternately an oscillation circuit may be associated with each individual light fitting. The frequency range may differ with individual light fittings by 10%, due to production tolerances of switching elements. Instead of a common power supply via a cable, an independent current source may be associated with each light fitting.

Title: Device for setting up and centring elongated workpieces, in particular on the entry side of a saw, in relation to a centring line
Inventor: SCHROEDERHEIM GUSTAF
IPC: B23D47/04
Filed: 1981-02-03
Abstract: To centre a workpiece (1), e.g. a stem, log or the like, in relation to a desired centring line (C) on the entry side of a saw or the like, two centring members (A1, A2) are arranged on each side of the centring line and are movable in synchronism towards and away from one another symmetrically in relation to the centring line under the action of a force (FT) directed towards the centring line. Each centring member carries two stops (B1, B2) which are arranged at a distance from one another in the direction of the centring line, project towards the centring line and are intended to come to bear against the workpiece. Each stop is flexibly movable in relation to its associated centring member transversely to the centring line between a projecting position and a pressed-back position and is under the action of a prestressing force (Fo) directed towards the projection position. The force (FT) acting on each centring member and directed towards the centring line is adapted in such a way that it is greater than the prestressing force (Fo) acting on an individual stop but less than the sum of the prestressing forces (2Fo) for both stops of the centring member. The device permits accurate centring of a workpiece without knots or other parts which project in places on the workpiece getting in the way. <IMAGE>

Patent DE-3122200-A1 (DE)
Title: Cutting and exposing apparatus for hop cultivation
Inventor: FISCHER MANFRED
IPC: A01G17/02
Filed: 1981-06-04
Abstract: The invention relates to a cutting and exposing apparatus for hop cultivation, having a pair of overlapping and self-sharpening cutting plates and a discharge device for material removed. Known devices of this type were either too large to be attached laterally beside the towing vehicle or operated unsatisfactorily such that they tended to become blocked up and set down the material removed in a non-uniform manner. The apparatus according to the invention avoids these disadvantages since, in it, a guiding surface receives the material which has been removed by the cutting plates and discharges it laterally. A discharge device, which is formed by an upright discharge plate with drivers, assists the satisfactory discharge of the material.

Title: Compacting beam for road finishers
Inventor: SCHRADER ERNST-AUGUST
IPC: E01C19/48
Filed: 1981-07-09
Abstract: In compacting beams for road finishers, the achievable compaction ratio of the material to be installed, which was previously 90%, is to be increased considerably in order to minimise or to avoid completely subsequent rolling work. To this end, the invention envisages the arrangement of a pre-compacting beam in front of the actual smoothing beam, the pre-compacting beam being provided with a sliding plate which is inclined at a setting angle in the direction of working and the compacting element being arranged between pre-compacting beam and smoothing beam. As a result, the material to be introduced and to be compacted by the compacting element is clamped in between the sliding plates of pre-compacting beam and smoothing beam so that the material cannot escape during the compacting stroke. The pre-compacting beam and the smoothing beam are expediently provided with vibration drives which are coupled to the drive for the compacting element in such a manner that the working stroke of the compacting element takes place only when the pre-compacting beam and the smoothing beam simultaneously exert a maximum pressure on the material to be installed.

Title: Method for the separation of pipes formed from strip material
Inventor: KLEIN NORBERT
IPC: B21C37/08
Filed: 1981-09-15
Abstract: In the production of pipe sections serving, for example, as inner pipes of exhaust silencers, a perforation is first of all punched into a strip material in a progressive die. The strip material is then deformed to give a pipe and welded longitudinally and the individual sections are then separated. The time available for separation is to a considerable extent determined by the strip speed, and the latter by the welding process. The material is weakened at a separation point by the punching out of slots or the stamping of a notch to leave less than 30% of the material and, after electric heating of this point, separation is carried out by melting off or striking off the continuously moving pipe section or pulling it off by using a higher belt speed in the last stage of the process.

Title: Method for correcting deviations in inking and damping in offset printers
Inventor: LUEBBE EVA
IPC: B41F31/00
Filed: 1981-10-14
Abstract: The invention relates to a method for correcting deviations in inking and damping in offset printers. The object of the invention is to develop a method which can be carried out independently of mechanical switching processes and with all the fault factors acting on the damping and ink being detected. The object is achieved in that the evaluation of the ink density values obtained by means of a densitometer takes place by means of an evaluation device and the output values obtained are used for the correction of the position of the ink metering elements, the ink ductors and the damp ductor. The monitoring strip applied to the printed products transversely to the direction of transport is designed in such a way that in each zone of the monitoring strip to be measured a full-tone field and two fields with line grids with different line width and the same surface coverage are measured in the printing direction. The evaluation of the measured ink density values permits, on the basis of the functional dependence between ink density values, damping and the ink film, the ink zone screws, the colour ductor and the damp ductor to be controlled. The quality of the printed products is thus increased.   <IMAGE>

Title: Drain valve for a blood pressure instrument
Inventor: STIEBLER FRANZ
IPC: A61B5/0235
Filed: 1981-11-17
Abstract: The drain valve for a blood pressure instrument shown can be manually switched into a quick-draining position and occasionally returns to its pumping-up and, as the case may be, normal draining position as a reaction to the first pump stroke. In a cylindrical inner space (2) to which a pump (5), the cuff (6) and an atmospheric orifice (31) are connected a control body (17) moves as a result of actuation of a handle (9) into the quick-draining position in which the connection between the cuff connection (4) and the atmosphere (31) is released by displacement of a sealing member (20) and in which a part-space (11) in which the pump opens remains separated. Actuation of the pump displaces the control body with the seal into the pumping-up and normal draining position by the pressure built-up in the separated part space, in which draining position the part space to which the pump is connected is connected to the cuff and is sealed against the atmosphere. <IMAGE>
