Title: Circuit arrangement for an electric multi-gate network for identifying complex reflection factors
Inventor: STUMPER ULRICH DR RER NAT DIPL
IPC: G01R27/06
Filed: 1981-03-21
Abstract: The invention relates to a novel measuring circuit arrangement for a linear passive electric multi-gate network (so-called six-gate reflectometer) for identifying the amount and phase of complex reflection factors of two-pole or multi-pole devices under test for any frequencies in the high and extremely high frequency ranges through measurement of the amounts of the amplitudes of electric signals or their powers on different outputs of the network. The circuit according to the invention is characterised firstly by the coupling-out of some of the high-frequency power of the high-frequency signal source (1) connected to the input gate (2) (see drawing) with the aid of a directional coupler (6), secondly by sampling the standing-wave field on a high-frequency line (7) connecting the directional coupler (6) and the output gate (3) with the aid of a plurality of coupling elements (10, 11, 12), thirdly through the insertion of components (e.g. an attenuator (19)) which have a wave-attenuating effect with adjustable attenuation between the output gate (3) and the coupling elements. In the measurement plane (4), the complex reflection factor of the connected device under test (5) can be identified using known evaluation methods from the four power values measured on the measurement gates (9, 16, 17, 18) with the aid of the power detectors (8, 13, 14, 15). <IMAGE>

Title: Multiple-winding reversing machine
Inventor: LEIFHEIT KARL HEINZ
IPC: B65H18/06
Filed: 1981-07-18
Abstract: In multiple-winding reversing machines, there is the problem of synchronising the speed of the empty winding core with the speed of the cloth web and the speed of the full winding core so accurately that the cloth web is held under uniform tension in every phase of the roll change. This problem has hitherto been solved by means of complicated synchronising controls which, however, work with insufficient accuracy. In the new multiple-winding reversing machine, there is provided between the winding cores and the winding drives a freewheel which ensures perfect synchronisation between the cloth-web speed and the empty winding core, without complicated control measures.

Title: Connection and fastening for handles, knobs and fitting parts in conjunction with crockery, furniture and implements of all types
Inventor: KAPPENSTEIN JOSEF W ING GRAD
IPC: A47J45/07
Filed: 1981-08-17
Abstract: Connections of this type have previously mainly been produced by rivet or screw attachments, the disadvantage being that, when connecting different types of materials with different expansion coefficients in conjunction with alternating temperature loads, expansion stresses occur which lead to rupture or detachment of the connections. The invention results in the possibility of handles and handle parts, knobs and fitting parts being functionally connected and fastened to one another without rivet and screw attachments, even when different types of materials are joined together under alternating temperature loads, for example ceramic, wood, plastic, glass, etc. connected to crockery made of special steel, steel, aluminium and furniture and implements of all types by means of spring-mounted steel attachment elements and their static spring pressure or tension, on two sides and in opposite directions or in a surrounding manner towards the inside or in a pressing manner towards the outside with engagement in the attachment regions provided.

Title: Barrel guide shaft for self-loading pistols with a locked breech
Inventor: BREUERS SEBASTIAN H J
IPC: F41A5/04
Filed: 1981-09-15
Abstract: In order considerably to improve self-loading (automatic) pistols, in the case of which the locking and unlocking of the barrel and breech is accomplished by means of a chain link, in terms of firing precision, the disadvantages of the locking system and those of barrel guidance must be overcome. For this purpose, a barrel guide shaft is installed which is firmly clamped in the grip, is held by slide stop pins (breech catch link pins) and replaces the barrel bush, the return spring guide and the chain link which are now used. The barrel is guided radially and axially by the barrel guide shaft in a firmly seated bush on the opening and a barrel closing element holder, by means of a control cam on the firing chamber. The control cam is shaped such that the barrel initially remains parallel in the longitudinal axis of the pistol, by lowering from the breech, before being unlocked. It is held on the grip, exactly in the firing direction, for the time (the movement) in which the fired projectile passes through the barrel, irrespective of the lateral and vertical play of the runners of the breech.

Title: Method and apparatus for constructing brick walls
Inventor: LISCHKE VOLKMAR
IPC: E04G21/22
Filed: 1981-09-29
Abstract: In a method for constructing brick walls, a foundation is laid and the position of the foundation is sensed by a sensor. A comparison with an envisaged horizontal is then made. Courses of bricks are aligned on the foundation in accordance with the comparison figures resulting from the comparison and, after each course, their alignment is compared with the envisaged horizontal. Deviations are compensated by in each case a layer of mortar to be applied between the courses and whose thickness is defined within in each case a permitted upper and lower limit. A brick-laying machine for carrying out this method consists of at least one transport unit which isolates the bricks and aligns them with respect to the calculated position. This transport unit is connected to a three-dimensionally movable lifting device having a gripping arm projecting above the brick wall. A metering device for the mortar is fastened to this gripping arm. A computer which calculates the position of each individual brick is provided to control the movement sequences of the transport unit, the lifting device and the gripping arm.

Title: Laboratory condenser
Inventor: LIEBISCH SIEGFRIED
IPC: B01L7/00
Filed: 1982-06-03
Abstract: The laboratory analysis of liquids is carried out by means of an evaporator with a downstream condenser. The distillation is carried out as a so-called reflux distillation or evaporative distillation. For each type of distillation, a condenser designed for this is required. The laboratory condenser according to the invention is characterised by two cooling chambers which are separated from one another by an evacuated insulating jacket. Into the cooling chamber located in the interior, a heat exchanger closed therein and formed from tube coils is introduced. The outer cooling chamber is provided with a reflux line which is connected via a distillation bridge to the cooling chamber located in the interior. In reflux distillation, the heat exchanger located in the inner cooling chamber is put into operation. The cooling chamber located on the outside can then be subjected to a coolant. In evaporative distillation, the heat exchanger is emptied and cooling is then effected merely by the coolant introduced into the outer cooling chamber. The type of construction of the condenser allows fixed fitting on an appropriately designed holder in a vertical position. In contrast to the known condensers, the condenser according to the invention is a universal vertical condenser. <IMAGE>

Title: Maintenance-free plastic post for lamps, traffic lights, traffic signs and the like
Inventor: LANGMATZ HANS
IPC: E04H12/02
Filed: 1982-11-13
Abstract: In the case of a maintenance-free plastic post with metal reinforcement, for lights and traffic signs for example, in order to avoid, in a simple and cost-saving manner, the expensive reinforcement in the form of a steel tube, until now deemed necessary in practice, and to make do with a reinforcement in the form of a bar or wire, the invention proposes constructing the post in a way known per se from an outer tube 2 and an inner tube 1 of smooth, impact-resistant plastic and filling the intermediate space 3 with a filling composition which firmly encloses and firmly holds the reinforcing elements 4 in such a way that, when bending loads occur on the post, they cannot cut into the core and which avoids during production the occurrence of air inclusions even at points which are not easily accessible. For this purpose, the filling composition comprises a mortar of a fine mineral cement with a small proportion of readily dispersible plastic, which in the pouring state is particularly fluid and thereafter, as it cures, encloses the reinforcing elements firmly and immovably. <IMAGE>
