Title: Multipack for six identical containers
Inventor: GLOEYER WOLFGANG
IPC: B65D71/02
Filed: 1987-11-23
Abstract: A multipack for six cylindrical, oval, square or hexagonal, dimensionally stable containers of identical shape and size arranged standing adjacently in two longitudinal rows, in the centre of which multipack there is a u-shaped cardboard blank which has a bottom surface and two side surfaces. Two containers are arranged standing inside the u-shaped cardboard blank. Two identical containers are arranged in each case on the same plane at the two outer side surfaces of the blank, which containers are firmly connected by at least one wrapping band which is stretched around the multipack in a plane parallel to the bottom surface to form a multipack with six containers. The u-shaped cardboard blank in the centre of the multipack prevents mutual slipping of the containers.

Abstract: A ventilating apparatus for the interior of a vehicle comprises a plurality of adjacent blowers 20, 30, (120, 130, 220, 230, 320, 330) (Figs 2 to 4). A drive motor 11, (111, 211, 311) common to all the blowers is coupled to the individual impellers of the blowers by a belt drive 12 (112, 212, 312). The drive motor which is common to all of them can be accommodated with space economy and in regions which are not otherwise useful. Various alternative positional relationships between the blowers and drive motor are disclosed (Figs 2 to 4) and moveable couplings (e.g. solenoid operated) may be provided to enable drive to a blower to be selectively uncoupled. Different size impellers or drive pulleys may be employed to achieve different blower capacities and a belt tensioning device (216, 217) (Fig 3) may be employed. <IMAGE>

Title: Process for the continuous reaction of sodium sulphate to give sodium hydrogen carbonate and gypsum by means of flue gas and lime
Inventor: PFLUG HANS D DR RER NAT
IPC: C01D7/02
Filed: 1988-05-07
Abstract: The invention relates to a process for the continuous reaction of sodium sulphate to give sodium hydrogen carbonate, by dissolving sodium sulphate in ammoniacal solution and then trickling it in a scrubber countercurrent to cooled flue gas, with sodium hydrogen carbonate partly precipitating because of its low solubility and being able to be separated off. To obtain, in terms of mass balance, an almost 100% yield, it is necessary to circulate the scrubber solution in the appropriate ratio to the fresh solution. The proportion of the solution transferred outwards from the scrubber flows into a degassing plant in which, in a first step, free ammonia and carbon dioxide are driven off, and, in a further step, bound ammonia is driven off after making alkaline with milk of lime (calcium hydroxide suspension). In the second degassing step, gypsum is simultaneously precipitated by reaction with sulphate. The gypsum is separated off, freed of coprecipitated carbonate by means of washing with sulphuric acid and again dewatered and washed. The distillates containing all the ammonia and the bottom product of the degassing plant desaturated of dissolved gypsum by means of carbonation with a substream of flue gas are recirculated via heat exchangers or coolers to the dissolving station for sodium sulphate. To maintain the water balance, a small substream of the bottom product from the degassing plant upstream of carbonation is discarded as effluent.

Abstract: The invention concerns a three-dimensional puzzle comprising a number of elements (60-70), each of which can be split into two pieces (68, 69). When assembled, the elements of the puzzle form a tetrahedron. In a preferred embodiment, the surfaces of the elements which lie on the outside of the tetrahedron when assembled each have part of a holographic puzzle. Thus when the pieces and elements of the three-dimensional puzzle are assembled correctly, the holographic puzzle is also automatically assembled correctly. In another preffered embodiment, the elements of the puzzle are hollow, so that several puzzles according to the invention can be fitted one inside the other.

Title: Electrical switching apparatus
Inventor: GOEHLE ROLF
IPC: H01H71/02
Filed: 1988-07-27
Abstract: In the case of known electrical switching apparatuses, various components are inserted into a common housing and are operatively connected to one another. The replacement of a component which has a different shape or size is in this case impossible. A novel electrical switching apparatus has a housing with integrally formed retaining ribs, guide pins and/or housing recesses which are prepared for retention and guidance and can be adapted to match the shape and size of the component provided for insertion. As an alternative, an adaptor component can be used which compensates for the differences in shape and size. The use of the novel switching apparatus is particularly advantageous in residual current devices and other service apparatuses. <IMAGE>

Title: Device for holding a telephone receiver
Inventor: QUERMANN KARL HEINZ
IPC: H04M1/04
Filed: 1989-03-23
Abstract: When using a telephone receiver, it has hitherto been known for the receiver to be held in one hand while only the other hand is free for further required work, for example thumbing through files, books or the like, or writing while making a call. In cases where both hands really need to be used, there is only the possibility of clamping the telephone receiver between the head and shoulder, which is uncomfortable, in particular when frequent and long calls are made. The invention is intended to enable more effective working while making a call. For this purpose, it is provided for a device to be designed in such a way that it comprises a support base (1) which stands on a table top or the like, a spacer (2) which is connected to it and a suspending device (3) into which the telephone receiver (4) can be suspended when in use. The invention enables both hands to be free for necessary work while making a call, without having to restrict the actual telephoning. <IMAGE>

Patent DE-3919465-A1 (DE)
Inventor: FISCHER ROLAND DR
IPC: H01F6/06
Filed: 1989-06-14
Abstract: The invention concerns inductance coils with cores of metal oxide ceramic, for example Y-Ba-Cu-O, for limiting the short-circuit current in power supply networks. To this end, the inductance coil is superconducting when operating on rated current and its protective currents keep the resulting inductance of the coil low. In the event of overloading, the winding of the coil produces a correspondingly high magnetic field in the core, which places it in the normally conducting state. This results in suppression of the protective currents and an increase in the resulting inductance, which limits the current. To ensure particularly high inductance in the normally conducting state, the superconducting core can be hollow and at least partly filled with ferromagnetic material.
