Title: Method for fixing an electro-acoustic transducer in a telephone housing
Inventor: AWAKOWICZ ERWIN
IPC: H04N5/64
Filed: 1983-03-30
Abstract: Method for fixing an electro-acoustic transducer (1) between a carrier plate (2) and a telephone set housing wall (4) which has sound outlet apertures (3). By means of this method, an electro-acoustic transducer (1) is intended to be disposed in simple fashion, in the correct position and soundproofed, below the housing wall (4) which has the sound outlet apertures (3). For this purpose, a retaining body (5) which surrounds the electro-acoustic transducer is first fixed on the carrier plate (2). Thereafter, the transducer (1) is inserted in the retaining body (5). The housing wall (4) is then connected to the edge area (9) of the retaining body (5) in such a way that the transducer (1) is tightly sealed. A circumferential sealing lip (8) is located on the inner surface of the retaining body (5), while the edge area (9) of the retaining body (5) is of elastic design and lies adjacent to the housing wall (4). The transducer (1) is centred by the sealing lip (8) located on the inner surface of the retaining body (5) and is pressed against the housing wall (4) so that the preceding space between the transducer (1) and the housing wall (4) is kept as small as possible. <IMAGE>

Title: Retaining element serving for the connection of flexible plastics tubes, arranged in parallel and spaced apart, to give a mat forming a heat exchange element
Inventor: HERBST DONALD DIPL ING
IPC: F24S10/75
Filed: 1983-04-18
Abstract: The invention relates to a retaining element by which a plurality of flexible plastics tubes, arranged in parallel and spaced apart, are connected to give a mat which can be used as an exchange element in a heat exchanger or else as a radiator, for example for a floor heating system. The retaining elements are fitted perpendicularly to the pipes, forming spacings; they consist of a flexible plastics material and have the object of uniting the pipes to form a mat, without impairing the flexibility of the plastics tubes, i.e. their bending about an axis perpendicular to them. They act as supports for the mat. The retaining element preferably consists of the plastics tube required for the production of the mat. The plastics tube is given, by a continuously turning apparatus with semicircular looping, a circular portion in which, in the course of the semicircular looping by mandrels advanced from above, the wall thickness of the outer side of the tube is deformed inwards until it comes up against the wall thickness of the opposite side. Thus, omega-shaped recesses are produced in the tube, at a spacing corresponding to the spacing of the tubes. The retaining elements are pressed onto the tubes laid in the form of a mat and securely receive the tubes in their omega-shaped recesses. <IMAGE>

Title: Burner chamber, preferably for baking ovens
Inventor: HENNIG WERNER
IPC: F23C9/08
Filed: 1983-05-27
Abstract: The invention relates to a burner chamber, preferably for baking ovens with recirculation of the heating gases, in which, in order to cool the burner chamber, the recirculating heating gases are conducted, in co-current or counter-current to the flame tube, through a double casing enclosing the burner chamber, before they are mixed with the burner gases. The aim of this invention consists in preventing the scaling of the double casing of the burner chamber in order to thereby increase the life of the burner chamber and also to achieve a better mixing of the recirculating heating gases with the burner gases. This is achieved according to the invention in that the double casing enclosing the burner chamber is constructed such that the recirculating heating gas stream flows through the double casing into a radial helical heating gas flow at the outer casing of the double casing and into an axial linear heating gas flow at the inner casing of the double casing.

Title: Collecting container for material crushed in a record shredder
Inventor: STROHMEYER WILLI ING GRAD
IPC: B02C18/00
Filed: 1983-07-04
Abstract: The fine particles produced in a record shredder, especially particles of film, do not settle at all readily in the collection container, because of their electrostatic charge. They spread around the surrounding area, especially when the collection container is removed from the shredder. A remedy is found according to the invention by making the inside walls of the collection container of an electrically conductive material, so that the particle charges are dissipated. The discharged particles settle in the selection container without problem.
Patent DE-3325230-A1 (DE)
Title: Method for improving heat transfer in a water/brine-air heat exchanger for circuit-bound heat recovery systems or analogously for other fields
Inventor: SCHILLING HEINZ
IPC: F28F13/06
Filed: 1983-07-13
Abstract: If it is desired to use a heat exchanger not only to transfer a maximum quantity of heat but in so doing simultaneously to maintain the temperature level as high as possible (for all heat recovery systems), it is a mandatory precondition in this that the heat exchanger is constructed to a purely cross-counterflow design and is operated with a heat capacity ratio of w = 1.0 (w = mL . cL : mW . cW). It has so far not been possible to satisfy the two conditions simultaneously. The idea according to the invention therefore relates to a method for removing the obstacles to date - too low a rate of flow in the water-conducting tubes (for w = 1.0), and water ducts which cannot be vented (in the case of pure cross-counterflow operation). This is performed according to the invention by providing the water-conducting heat exchanger tubes with a twisted filler insert which converts the tubular cross-section into an annular cross-section and thus also increases the water velocity at the heat-transferring surfaces in conjunction with a lower water throughput. It is also possible as an equivalent for a plurality of tube layers to be combined to form a water duct and always to project horizontally. The heat exchangers thus produced for max. heat transfer are provided at the periphery with an arrangement of gates, by means of which each water duct can be separately vented and taken into operation, and the heat exchanger thereby becomes wholly functional.

Title: Process for extracting liquids from foodstuffs such as fruits and vegetables
Inventor: TICHY OLDRICH JIRI
IPC: A23L2/04
Filed: 1983-07-27
Abstract: A process for extracting juice from edible solids and semi-solids, for example fruits or vegetables, is proposed, in which the starting materials are first sliced into small strips and are then pressed. As a result of the slicing, numerous channels for draining the juice are created in the pulp (in the presscake). The juice yield is considerably increased as a result. It is further proposed to warm the slices to about 29 DEG C prior to pressing. A further increase in the juice yield occurs as a result. Using the process, material can be first sliced and pressed, then the presscake can be mechanically loosened again and pressed again. The process can be repeated several times.

Patent DE-3333538-A1 (DE)
Inventor: SCHMERMBECK DIETER
IPC: C09D5/20
Filed: 1983-09-16
Abstract: In a process for producing coatings adhering to the surface while being removable, a treatment liquid is produced from PUR elastomers enabling a thermoplastic treatment by admixing a solvent. Said treatment liquid, fluid or viscous depending on the mixture ratio, is applied to the surface and forms after evaporation of the solvent a coating adhering solidly to the surface while being completely removable if required. Even in the case of a thin wall, said coating has an excellent tear resistance while being elastic and flexible. Its surface is absolutely tight and it provides a reliable protection against the mechanical effects and the like. It is preferably used for the reconditioning and the repair of tyres of motor vehicles, the necessary rubber envelope being replaced by the coating. Said coating may also be used as a protection against oxidation and adverse mechanical influences for the rough lower surface of the prefabricated rubber tread for the reconditioning of tyres of motor vehicles.

Title: Stacking device for long, narrow wooden boards
Inventor: FROEHLICH ADOLF PETER DIPL ING
IPC: B65G57/18
Filed: 1984-02-23
Abstract: The stacking device for long and narrow wooden boards operates in such a way that the individual boards pushed on a support device 10, 11 no longer stand exactly upright, but are placed at a slight angle, so that they rest against a bearing edge. The said bearing edge is formed by a transverse slide 12, which also advances the individual stack on a discharging track 7. A holding-up device 8 which is arranged above the discharging track and is placed at a corresponding angle prevents the upsetting of the individual stack, which has been produced beforehand and advanced, until an overall batch has been assembled which is sufficiently stable. The holding-up device may be raised, so that the individual stack which has been advanced by the transverse slide can, if necessary, be advanced together with the individual stacks assembled beforehand. If an individual stack is pushed through under the raised holding-up device, the holding-up device is lowered again and in this way prevents a collapse once the transverse slide has been pulled back into its starting position. <IMAGE>

Patent DE-3419367-A1 (DE)
Title: Method and device for applying fluids to substrates passing through
Inventor: MITTER MATHIAS
IPC: D06B19/00
Filed: 1984-05-24
Abstract: The pile of a carpet or of another substrate is treated with a foam fluid which is applied through the opening of a slit doctor to the underside of a tubular carrier through which the fluid is fed. The carrier can rotate about its axis inside a screen-print template so that the outlet of the opening, viewed with respect to the alignment of the substrate, can be moved forwards or backwards. This determines the degree of penetration of the fluid into or through the substrate and/or the amount of fluid which is applied per unit area of substrate. The angular adjustment of the application element can also bring about a stabilisation of the relatively thin screen-print template which is easily deformable. The same effects can also be achieved if the support for the substrate is appropriately moved in relation to the application element. <IMAGE>
