Title: Method for increasing the efficiency of or for purging at least two heat exchangers for exhaust gases from internal combustion engines of stationary installations
Inventor: KRAMB JAN ING GRAD
IPC: F01N5/02
Filed: 1983-07-18
Abstract: The invention relates to a method for increasing the efficiency of or for purging heat exchangers for exhaust gases from internal combustion engines of stationary installations for operating heat pumps or for coupled generation of power and heat, the heat exchangers being heated temporarily after evacuation of a liquid secondary heat-transporting medium by the hot exhaust gases to a temperature sufficient for purging the heat exchanger surfaces. The method according to the invention is a development of the method as described in more detail in the main application P 3243114.7. In the method according to the invention, there is the advantage that the evacuation of the heat exchanger is performed automatically. According to the invention this is achieved when the method is carried out using two heat exchangers and, if appropriate, a compensating tank for the heat-transporting medium, it being the case that for the purging of one of the heat exchangers the latter is disconnected from the circulation of the heat-transporting medium, and by heating and evaporating the secondary heat-transporting medium the heat exchanger is evacuated and there is subsequent heating by means of the hot exhaust gases to a temperature sufficient for purging. These two heat exchangers can be connected either in parallel or in series in the two embodiments of the method according to the invention.

Title: Method of determining the termination of compaction in vibratory machines
Inventor: GRESCHNER JOACHIM DIPL ING
IPC: E02D3/074
Filed: 1983-10-06
Abstract: The invention relates to a method of determining the termination of compaction in vibratory compaction machines with at least one rotating unbalanced mass, for example in vibratory rollers, the degree of compaction of the object to be compacted being used as a criterion for the termination of compaction and being determined via quantities measurable at the vibratory compaction machine. The aim is to provide a method which is simple to manipulate with little effort and can be used without restrictions. To this end, the termination point is to be determinable with relatively simple means as a function of the degree of compaction of the entire fill and thus the number of passes is to be minimised. According to the invention, a maximum vertical rolling-body vibration path is constantly set during each individual pass, and in addition at least one parameter of the vibrating part or parts is detected. This parameter or these parameters serve as a measure of the degree of compaction and are processed in a suitable manner in an analysing device. <IMAGE>

Title: U-shaped closure clip for tubular or bag-type packaging wrappings
Inventor: KOLLROSS GUENTER
IPC: B65D33/16
Filed: 1983-11-01
Abstract: In a U-shaped closure clip made of metal strip material for tubular or bag-type packaging wrappings, the material profile consists, according to the invention, of a substantially rectangular base part, forming the inner region of the clip and having a width which is a multiple of the height, and of a rib part which forms the outer side of the clip and is constructed to be symmetrical to the central vertical plane on the base part, and whose height is at least equal to the height of the base part. The moment of resistance of the clip is thus increased considerably relative to the circular cross-section; the clip can be guided securely during closure, as a result of which twisting of the clip limbs is avoided. The wrapping to be closed is gripped reliably over a relatively large length and sealed off. The new profile can be used both in individual clips and in strips of clips. <IMAGE>

Title: Spectacle frame having spectacle bows arranged pivotably on the spectacle frame
Inventor: WEISS ARTUR
IPC: G02C5/22
Filed: 1984-04-18
Abstract: In a spectacle frame in which the spectacle bows can be pivoted out beyond their normal position of use against the restoring force of resiliently elastic restoring elements, the restoring elements are constructed as resiliently yielding latching devices which have a latching position which is assigned to the position of use of the bows and in which the bows are fixed in each case by means of a minimum retaining force. In a second latching position of the restoring elements, the spectacle bows are yieldingly fixed in their basic position suitable for storing the spectacles. Each bow is attached to a cylindrical hinge piece which is mounted to be capable of rotation about the pivoting axis of the bow and has a square external cross-section. Provided on the spectacle frame are leaf springs which, being resiliently prestressed, bear in each case against one of the external surfaces of the hinge piece and therefore yieldingly fix the latter in positions which are offset by 90 DEG with respect to one another. The maximum angle of adjustment of the spectacle bows is limited in each case by a hinge stop.

Title: Reciprocating piston engine without free reaction torques from the piston side forces on the engine supports
Inventor: PULCH JUN OTTO
IPC: F16F15/24
Filed: 1984-11-30
Abstract: The invention relates to spark-ignition or diesel reciprocating piston engines with four or more cylinders in which the reaction torques on the supports resulting from the piston side forces cancel each other out. The object on which the invention is based is to design reciprocating piston engines in such a way that the reaction torques arising during the production of the torque cancel each other out and have no effect on the engine supports. This object is achieved according to the invention by virtue of the fact that the engine is divided into two identical halves with opposite directions of rotation and respective cylinders in the right-hand and left-hand half ignite simultaneously. The two coaxial crank shafts are connected to one another via bevel gearwheels.

Title: Floating parking of passenger cars
Inventor: MEIER-HEDDE KARL-HANS
IPC: E04H6/12
Filed: 1984-12-15
Abstract: In the main claim, the invention wishes to claim floating parking. The invention is based on cablecar technology B 61 B and the electronics for multi-storey car parks and lifts. The worldwide lack of parking spaces for passenger cars in built-up areas is to be considerably reduced. Floating parking solves this problem. This is achieved by newly developed special pallets and a special cablecar guide at the entry and exit points. The passenger-car driver drives forwards onto a pallet and takes a parking chip. Later on, his car is returned to him by means of this chip. The park and float installation automatically affords provision, raising, transporting and floating parking and turning, and, after call-up by the driver, the lowering and presentation of the pallet with car. Possible applications are:     extending parking possibilities above existing parking spaces; new provision of parking possibilities above land which cannot be driven on and, temporarily, over land which should not be driven on;   crossing breaks in carriageways in a floating manner;   floating storage.   <IMAGE>

Title: Communication system for videoconferences
Inventor: BOERGER GEORG PROF DR ING
IPC: H04N7/15
Filed: 1985-02-26
Abstract: Videoconferences are intended to avoid the time and expense of travelling to a common conference location. However, to ensure that the conferees can see and hear one another and show one another written documents and objects continuously and simultaneously, technical equipment is required, the cost of which depends on the one hand on the number of conference locations which are to interconnected and on the other hand on the measures enabling a reduction in the requirement for transmission capacity and terminal equipment. As in the known videoconferencing forms - >>studio conferences, meeting room conferences and workstation conferences<< - the picture and sound signals are intended to be switched over and/or mixed. The technical equipment required for this purpose, however, no longer has to be at the respective connectable location if a central videoconference station BZ is provided which contains this technical equipment - furthermore only to an extent commensurate with the actual videoconference traffic density. Each connectable location SO needs to be equipped only with the terminals EE which are also required for TV-quality videotelephones. Furthermore, the picture/sound can be controlled individually from each location SO. <IMAGE>

IPC: F15B13/08
Filed: 1985-04-16
Abstract: The pneumatically actuated devices of the electropneumatically controlled apparatus are each connected via an electropneumatic control-valve unit (6) to the storage space (15) of a compressed-air accumulator (7). The compressed-air accumulator (7) consists of an extruded section (17) which is closed on both sides by screwed-on end plates (32, 33) and, apart from the chamber part forming the storage space (15), has two smaller chamber parts (19, 20) arranged next to one another. The connection ports of the valve-control unit (6) directly adjoin bores (21, 22, 24) of the extruded profile, which in each case connect the chamber parts (15, 19, 20) to the main valve and auxiliary valves of a valve-control unit (6) so that pneumatic hoses are avoided for this. The compressed-air accumulator (7) is simple to manufacture in various sizes adapted to the respective air requirement and the dimensions of the apparatus. The weldless construction and the use of a plurality of accumulator units connected to one another via hoses increase the safety of the apparatus. <IMAGE>
