Title: Expanded polystyrene mouldings prodn. - by heating pre-expanded polymer in tube to vaporise introduced moisture, and injecting into mould
Inventor: HAHN ORTWIN PROF DR
IPC: B29C44/34
Filed: 1980-08-27
Abstract: Thermoplastic foam moulding, partic. in expanded polystyrene, is produced by pre-expanding the material, introducing it into the mould, foaming to shape by feeding in hot water vapour, subsequently heating if required, and ejecting from the mould. The polymer is pre-expanded by heating without any water vapour and immediately before injecting into the mould. The process prevents condensation/sticking or sintering effects.

Patent DE-3106174-A1 (DE)
Title: DC voltage converter
Inventor: SIMMON DAVID HARRY
IPC: H02M7/5387
Filed: 1981-02-19
Abstract: A feedback-controlled DC voltage converter for use as an energy source is described, which has a transformer whose primary circuit is energised in push-pull operation, in order that current pulses are supplied alternately in opposite directions through the primary winding, the rectified output from the secondary winding of the transformer controlling a regulator as a function of the voltage drop across the load, when a load is applied. In such a converter, according to the invention, the regulator controls the time periods of the current conducting capability of at least one pair of electronic switches which conduct current alternately in the primary circuit (energised in push-pull) of the transformer, while the time periods of current conducting capability of one electronic switch of the pair, or of each pair, of electronic switches overlap with the time periods of current conducting capability of the other electronic switch of the same pair. During operation, voltage stabilisation is achieved on the basis of the property that the time periods of the overlap increase as the voltage drop across the load decreases, and the time periods of the overlap reduce as the voltage drop across the load increases. The electronic switches are preferably represented by two pairs of transistors, and an inductor in the primary circuit represents the single circuit element which stores energy during each overlapping period.

Title: Potty for babies
Inventor: SCHOETTLER HANS
IPC: A47K11/04
Filed: 1981-03-06
Abstract: In the case of a potty for babies, acoustic encouragement to pass water is to be provided. This object is achieved in that a pad (2) is provided which forms at least part of the sitting surface, can be filled with a pressure medium and has a value arrangement which is opened, to make a noise, when a weight acts upon the pad. According to a preferred embodiment, the pad (2) may take the form of an annular tube made of conventional plastic and the potty may be provided with an annular edge (1) for insertion of the annular ring. The inherent weight of the child placed on the potty causes a thin jet of a small quantity of water to be expressed out of the valve and to be squirted with a splashing sound into the collecting cavity (6).   <IMAGE>

Title: Electronic lotto gambling machine
Inventor: BECK RALF
IPC: G07C15/00
Filed: 1981-03-13
Abstract: In an electronic gambling machine, random numbers of a predeterminable range of numbers are generated and displayed and shown in the six- or different-part form needed in each case, the display element being constructed as at least six-part display with series-connected display units and memories and being allocated to a clock generator with counter. Between the individual memories, comparators are connected in such a manner that the appearance of a number already stopped is impossible. A correspondingly high pulse repetition rate of the clock generator ensures that the numbers stopped via transmitters of variables are also really random numbers. The housing is constructed of honeycomb shape, the cover being divided into two levels and a connecting diagonal which are in each case used for accommodating the keys, the display or other symbols. This creates a very clearly laid out machine. <IMAGE>

Title: Process and apparatus for continuous mashing in cereal distillation
Inventor: SCHNECK EMIL
IPC: C12C7/06
Filed: 1981-05-14
Abstract: The milled cereal is carried through with vigorous agitation in a mashing vessel (5) at temperatures just below the boiling temperature by use of the cooling water obtained in mash cooling and the vapours obtained. The mash is then heated by steam in the high pressure heater (8). A continuous mash stream is then delivered into a partial depressuriser (10) in which, in a first cooling, only as much vapour is generated as is re-used in the process. A stepwise cooling of the mash stream is then carried out respectively to the liquefaction, saccharification and pitching temperature in continuous counter-current with the cooling water which itself is continuously produced stepwise at virtually the boiling temperature, as used in this case in mashing. <IMAGE>

Title: Process for the preparation of 3-hydroxybenzoic acid
Inventor: GABEL EIKE DIPL CHEM DR
IPC: C07C51/367
Filed: 1981-06-04
Abstract: 3-Hydroxybenzoic acid is obtained from an industrial 3-sulfobenzoic acid mixture containing sulphuric acid and/or sulphur trioxide, which mixture contains at least 75 % by weight of 3-sulfobenzoic acid, based on the total organic constituents present, and at most 35 % by weight of sulphuric acid and/or SO3, based on the total mass, by reaction with alkali metal hydroxide at a temperature of 220 to 450 DEG C and at a pressure of 1 to 120 bar. For this purpose, this industrial 3-sulfobenzoic acid mixture, if required after dilution with the same volume of water, is mixed with enough 50 to 100 % strength by weight alkali metal hydroxide, the remaining 50 to 0 % by weight being essentially composed of water, so that after neutralisation of the sulphuric acid and the total sulfo groups and carboxyl groups, 2.5 to 8 mol of alkali metal hydroxide are present per mole of 3-sulfobenzoic acid. During the pressure hydrolysis, if required further water is added so that 10 to 45 % by weight of water are present in the batch. The reaction mixture, if required after dilution with water, is acidified by mineral acids to a pH of below 4 and the 3-hydroxybenzoic acid is isolated at temperatures in the range from -5 DEG C to +40 DEG C.

Abstract: In a window installed obliquely and having a casement (5) articulated at the top, the latter is additionally connected to the window frame (1) by means of a lifting arm (6), one end of which is mounted on a pivot (7) on the window frame (1), whilst the other end is displaceable in the casement (5) and loaded in the direction of the hinge pin (4) by a tension spring (10). This spring, at its end located nearest to the hinge pin, is connected to a further lifting arm (13) which is likewise mounted on a pivot (14) of the window frame and which together with the first lifting arm (6) forms a kind of scissor or toggle mechanism, the legs of which are loaded relative to one another by the tension spring (10) and both thereby exert a torque effective in the opening direction on the casement. The total torque effective in the opening direction can thereby be adjusted in such a way that it is relatively high with the window closed. <IMAGE>

Title: Magazine for push-in electrical assemblies
Inventor: NIEDZELA GERHARD DIPL ING
IPC: H05K7/14
Filed: 1981-12-02
Abstract: In magazines for push-in electrical assemblies it was normal to insert external cables that are at risk of excess voltages into the individual assemblies and to protect them there by means of protection modules, for example excess voltage suppressors. The plug connections for separation and connection were arranged in the front apertures of the assemblies. According to the invention, the plug connections (13) and the protection modules (7) are combined on a separate assembly. In this way, the excess voltages are kept remote from the functional assemblies. As a result of the fixed arrangement of protection modules and plug connections it is possible to use normal distribution elements for the main distributors. <IMAGE>
