Patent DE-3347285-A1 (DE)
Title: Process for the production of calorific heat and also heat generator for the performance of the process
Inventor: LAUBKEMEIER FRIEDHELM
IPC: F25B29/00
Filed: 1983-12-28
Abstract: In the known heat pumps, a refrigerant which is not harmless is principally subjected to a phase change. The conversions into the liquid or gaseous physical state mainly involve considerable losses of work. According to the process belonging to the invention, air is preferably used as the working medium, and the gaseous physical state is retained in changes of state which proceed predominantly isothermally. The associated heat transfers are completed in a direct manner, i.e. without interposed heat exchanger and changeover processes. The heat generator (see Figs. 1 and 2 of the description) belonging to the invention contains the device for directly receiving the compression heat, in the form of a pressure vessel (4) partially filled with liquid and also one or more spray nozzles (6.3) in the working space (2.1) of the working cylinder (2) for spraying in liquid from heat sources of the environment. For the production of heating water at 40 DEG C with a heat source temperature of 10 DEG C, a performance number of 6.1 can be achieved, in contrast to about 3.0 with known heat pumps. The process and generator can in general be used where heat is required for heating buildings and for hot water production. <IMAGE>

Title: Device for holding, guiding and driving cartridges
Inventor: VOLLMER JOSEPH DIPL ING
IPC: F41A9/43
Filed: 1984-04-10
Abstract: For transporting cartridges to the weapon in automatic loaders, a device is used in which the guidance and drive take place by means of double-toothed tooth belts or tooth belts with a special profiling on the rear of the belts on guide webs which are arranged concentrically around the cartridge. In consequence, the cartridges on the transportation path are guided and held exactly, and are shackled to the drive device. There is no friction between the cartridge and the cartridge guide. Utilisation of this principle as a cartridge holder in ammunition magazines is possible without there being any need for special locking. <IMAGE>

Title: Spray device for diecasting or injection moulding moulds
Inventor: FINK ROLAND
IPC: B22D17/20
Filed: 1984-06-14
Abstract: A spray device is described for the application and distribution of parting, cooling or preserving media to diecasting or injection moulding moulds, with a nozzle head conducting spray air or spray medium to a mixing nozzle. Furthermore a device for the regulation of the quantity to be sprayed out is provided, with at least one rotary cap rotatably held on the nozzle head to influence the shape of the spray stream. The nozzle head is pivotably held, at its end remote from the mixing nozzle, with spherical abutment surfaces in a supply chamber, divided into two partial spaces, of a housing. These partial spaces are respectively acted on with spray air or with spray medium, which are conducted through connection openings in the spherical abutment surfaces and through bores, separately through the nozzle head to the mixing nozzle, where they can be throttled, for regulation of the spray stream, by a rotary cap screwed to the nozzle head. This design has the advantage that a nozzle head results which is relatively simple to handle, and on which no lateral connections have to be provided which would impair its pivotability.

Title: Electrical installations which are proof against disturbing arcs
Inventor: PETRY HANS DR ING
IPC: H02B13/025
Filed: 1984-07-03
Abstract: The effects of disturbing arcs in switching installations and other electrical installations, which effects are hazardous to personnel and objects, can be prevented by the arc energy being passed into filters where this energy is used for the rapid heating of solid filter materials. Compressed steel swarf, from machining manufacture, is suitable, for example, as the filter material. The filter material is located in pressure-tight metal containers. Air-filled containers can additionally be arranged in front of and behind the filter containers, in order to absorb pressure.

Patent DE-3436133-A1 (DE)
Inventor: ANGER WILHELM
IPC: G02C13/00
Filed: 1984-10-02
Abstract: The process in accordance with the present invention is especially well-suited for the preparation of spectacles with a correction effect which are adapted both optically and mechanically, whereby the mechanical adaptation is objectified to at least a considerable degree and the mechanical adaptation depends to a lesser extent or not at all on subjective evaluations of the fits of the spectacles on the part of the fitter or the spectacle wearer. For each nose piece of the spectacles the location of at least one nose point on or near the contact surface at which the bridge reposing surface touches the nose, is measured in space relative to two reference points, for example, the eye centers. From this nose point measurement the location of the pad nose piece reposing surface which the latter is to occupy in space on the completed spectacles is determined, which occurs, for example, under the assumption of pressureless contact between the contact surface and the reposing surface. Corresponding to this determination the nose piece of the spectacles are physically shaped, specifically in their correct relative position with respect to the lenses since a target position has been predetermined for the lenses with respect to two reference points in space.

Between the two reactor stages is provided an acceleration rotor for the solid/gas mixture, which again comminutes the calcium hydroxide additive for further activation of the reaction. By means of the apparatus, a high proportion of additive returned in circulation is aimed at. <IMAGE>

Title: Peroxide composition for core material and mould material
Inventor: KAWAKATSU YASUYUKI

Patent DE-3513376-A1 (DE)
Title: Thin film evaporator
Inventor: DEUBLEIN DIETER DR
IPC: B01D1/22
Filed: 1985-04-15
Abstract: Thin film evaporators serve for treating flowable substances to generate a vaporous product, called vapours. Hitherto, these vapours generally flowed into a cylindroconically shaped attachment on the evaporator part and left it tangentially through an outlet nozzle. The vapours previously flowed through internals for demisting. This form of vapour removal causes considerable pressure drops which are generally compensated for by a radial fan on the shaft of the stirrer system. According to the invention, these disadvantages are avoided by a vapour removal nozzle (2) configured as a pipe bend, which nozzle is attached to the evaporator part (1) and has an internal diameter identical to or approximately identical to the internal tube wall of the evaporator part. Owing to the rotating vapour flow with centrifugal demisting, demisters are generally not required.

Title: Method for preparing a solderable coating on a substrate and printed circuit board, or solderable contact surface
Inventor: JAKOB GUENTHER
IPC: C04B41/52
Filed: 1985-05-03
Abstract: Low-resistance and solderable printed conductors and contact surfaces are obtained by the initial application to an insulating substrate (10) of a first layer (11, 12, 13) of an electrically conductive coating which contains the following components:     an adhesive binder, for example based on synthetic resins; electrically conductive particles in the form of carbon and/or metallic carbides and metal particles of a metal which in the electrochemical series of elements is less noble than a solderable metal. After curing of this first layer, the substrate with the first layer is brought into contact with a solution (for example by dipping or spraying) which contains ions of the solderable metal (e.g. copper, silver or gold), by which means a second layer (14, 15, 16) of the metal ions is applied to the first layer in a purely chemical way. <IMAGE>

IPC: D01H4/16
Filed: 1985-05-17
Abstract: In a process and apparatus for open-end spinning, the fibres are drawn discontinuously out of the fibre tuft of a fibre sliver. The fibres are then fed to a collecting surface by means of mechanical transport elements, during this transport the front fibre ends being retained and the rear fibre ends being free. The transport direction for this transport is essentially counter to the yarn draw-off direction, so that the fibres are tied into the yarn with their rear fibre ends in front.
