Title: Method for the harvesting of field fodder
Inventor: EGGENMUELLER ALFRED DR ING
IPC: A01D90/04
Filed: 1987-11-27
Abstract: The invention relates to a method and devices for carrying out this method for the harvesting of field fodder, the crop being picked up from the ground, comminuted by a cutting device 26 and fed to a storage space 34. In order to achieve a high compaction of the crop, there is arranged downstream of the cutting device a pressing device 30 which, by means of the tine rotor 31 and the tines 20, breaks up, squeezes and crushes the crop during its passage through the grooves 15. The crop, when conveyed further into the pressing channel 33, is compressed and matted as a result of the counterpressure built up there. By changing over the guide plate 28, the pressing device 30 can be bypassed, and the crop can be transferred, without being pressed, into the storage space or a transport vehicle coming alongside. Furthermore, proposals are made for installing such a pressing device in a loading truck. The pressed crop no longer springs open, and therefore a high storage density is achieved even in the case of storage at a later date. <IMAGE>

Title: Cartridge ejector for a firearm, especially a small calibre competition firearm
Inventor: STRAUB DIETER
IPC: F41A15/14
Filed: 1988-04-18
Abstract: A cartridge ejector for a firearm, especially a small calibre competition firearm, holds the empty casing to be extracted firmly during part of the extraction movement. This part of the extraction movement is completed by positive opening of the cartridge extractor, which allows the casing to fall out. This is in consequence carried out under the influence of the force of gravity, expediently via a slide (50) to the inlet opening (34) of a casing collecting device (30) which is held in the system (10). In consequence, the previously normal side ejection of the casings and the disturbance to the gunner himself and to his neighbouring gunner on the firing post caused by this are prevented. The empty casings can occasionally be emptied from the system all together by removing the casing collecting device (30). <IMAGE>

Patent DE-3822699-A1 (DE)
Inventor: PRAUSE REINHARD DIPL ING
IPC: G01S15/10
Filed: 1988-07-05
Abstract: In a process for ultrasonic measurement of transit time in liquids or solids by the pulse reflection method, a test head (24) emits a shock wave pulse which traverses an approach section (22), partly penetrates the test object (pipe 20), and is partly reflected at the surface of the latter. An echo start signal is derived from this entry echo which is reflected into the test head from this surface or from a reflection of the beat from the back surface (start echo), and used to start the transit time measurement (echo start) which is stopped by a subsequent start echo (wanted signal 68) when the amplitude of the latter exceeds an adjustable threshold value (e.g. 62). The magnitude of the threshold value associated with the echo start signal is varied over time to match the variation in amplitude over time of the start echo. The threshold value is high during a first threshold (58) of variable magnitude and then decreases linearly in accordance with a predetermined function within a variable time-interval to a second threshold (62) of variable magnitude.

Title: Cooling of moulds and calibrating means for the processing of thermoplastics
Inventor: SCHMIDT DETLEF
IPC: B29C45/73
Filed: 1988-08-12
Abstract: In the cooling of moulds and calibrating means for the processing of thermoplastics, the cooling channels of the moulds/calibrating means operate as the evaporator of a refrigerating plant. Refrigerant evaporates in the cooling channels and, due to the change in its state of aggregation, extracts considerable amounts of heat from the mould and/or calibrating means. As a result, significantly better cooling can be achieved than with conventional cooling, which relies on a cooling medium such as water taking up heat by forced convection.

Title: Intake device for an internal combustion engine
Inventor: GARTNER JURIJ
IPC: F02B27/02
Filed: 1988-08-31
Abstract: An air chamber is arranged so that it can rotate concentrically inside a cylinder intake pipe arranged in a circular shape. Each air chamber has a lateral inlet aperture and an outlet aperture opening into the intake pipe. Intake devices of this type are known in the form in which the effective intake pipe length can be varied by rotation of the air chamber. According to the invention the intake pipe side walls are also displaceably arranged in order to obtain a reduction of the effective intake pipe cross-section whilst simultaneously increasing the effective intake pipe length. To this end the said side walls are carried in helical guide grooves of the air chamber wall. The two side walls of an intake pipe are thereby displaced towards one another as required by rotation of the air chamber.

Title: Carbonic acid power station
Inventor: TREPTOW ROLAND
IPC: F01K25/10
Filed: 1989-03-13
Abstract: The aim is to permit a closed thermal cyclic process, especially one which takes place in coal-fired gas or steam turbine plants (installations) for generating electric power, at a temperature level which is low in accordance with the invention, in conjunction with a comparatively high thermal efficiency and final raising of the efficiency of fuel use. To this end, this plant utilises the thermo-dynamically very effective characteristics of a liquid which boils at a relatively low temperature, such as, preferably, CO2, carbon dioxide ("carbonic acid"), which is incombustible and also represents no handling problems, by employing it here as a circulating evaporation and working medium.

Patent DE-3920430-A1 (DE)
Inventor: UEBEL HELMUT DIPL ING
IPC: G01R31/02
Filed: 1989-06-22
Abstract: A circuit arrangement for monitoring AC loads, fed via capacitive cable feedlines, in railway signalling systems is disclosed which permits the current flow through the respective load to be reliably monitored by evaluating the current (I) fed into the cable feedline, independently of the length of the cable feedline. The current (I) flowing into the cable feedline flows through a monitoring element (G), which responds to the mean value with respect to time of the current flowing through it, only during one of the half cycles of the feed voltage (U). During the other half cycle of the feed voltage it is bypassed in a low-impedance fashion by a switch (S) controlled synchronously with the feed voltage. Since the capacitive reactive current has the mean value 0 during one half cycle of the feed voltage, the circuit arrangement detects only the real current component, which reproduces the load current, of the current fed into the cable feedline. <IMAGE>

Abstract: An assembly for indicating the angular position of a rotary mechanism (e.g. a valve) with which the assembly is operatively connected has inner and outer cylinders which can be rotated relative to each other. The curved surfaces (20, 35) of the cylinders have areas (25 - 27) of contrasting colour so as to provide different visual effects depending on their relative positions. The areas extend axially and circumferentially and each at least in part decreases axially as it extends circumferentially so that even if part of the outer surface of the outer cylinder is obscured from sight the visual effect and thus the angular position can be observed. The areas may be helices. The surfaces could be conical. Various combinations of colour and area are described. <IMAGE>
