Patent DE-3028519-A1 (DE)
Title: 2,5-Tri:oxa-bi:cyclo-(2,2,2)-octan-6-one derivs. - and 3,6,8-tri:oxa-(3,2,1)-octan-4-one derivs. are a stable combination of glycerol and alpha-keto carboxylic acid
Inventor: SCHAEFER GERT DIPL CHEM DR
IPC: C07D493/08
Filed: 1980-07-28
Abstract: octan-6-one derivs. (I) and 3,6,8-trioxo-(3,2,1) octan-4-one derivs. (II) are new (where R is opt. branched 2-18C alkyl opt. carrying further gps., or opt. substd. aryl or araliphaticyl; R is pref. the residue of an essential amino acid precursor R-CO-COOH). (I) and (II) are prepd. by reacting an alpha-keto-carboxylic acid deriv. of the formula R-CO-COOH (III) or an ester, ketal ester, halide or comparable deriv. thereof with glycerol or with a glycerol deriv. which releases the glycerol residue at a reaction temp. below 160 deg.C which gives a sufficient reaction rate, in the presence of an acidic catalyst, the resulting mixt. of (I) and (II) opt. being sepd. into the pure components. (I) and (II) are useful as intermediates for pharmaceuticals. Ine one molecule, they combine the features of an alpha-keto carboxylic acid (which can be metabolised to the corresp. alpha-amino acid) and of glycerine (which is involved in carbohydrate metabolism) with the advantage of surprising stability on storage; they can thus be used in human and veterinary medicine in connection with amino acid metabolism, as well as as foodstuff components for humans, animals and microorganisms. (I) and (II) can additionally be used as a stable storage form of amino acids.

Title: Method for producing a fibrous and/or granular material, device for carrying out the method and use of the fibrous and/or granular material
Inventor: FREI JOSEF
IPC: B09B5/00
Filed: 1981-02-16
Abstract: So that, during the production of a fibrous and/or granular material from domestic, agricultural, forestry, organic, industrial and/or commercial waste, it is not necessary to separate out waste in the course of the production method as unusable material, the waste which is to be processed is firstly subjected in a disintegrator unit (3) to disintegration treatment and the disintegrated waste is divided up into three fractions after the separating out of any metal components by means of metal separation units (5, 6). The division takes place by means of a fractioning unit (10) a) into a fine grade fraction which does not exceed the desired final size of the waste, b) into a mechanically easily processable coarse-grade fraction, and c) into a coarse-grade fraction which is difficult to process mechanically. The two coarse-grade fractions are subsequently comminuted, separately from one another, to the desired final size of the waste in comminution units (14, 15) which are matched in an optimum manner to the coarse-grade fraction to be processed. Subsequently, all three fractions are dried in a drying unit (18) by heating and extracting the water vapour produced in this process, to a specific maximum residual moisture content, and sterilised. By means of a further fractioning unit (23) and air separators (24, 25, 26) it is fractionated into a heavy fraction (29) which consists predominantly of inorganic granules, into a lightweight fraction (28, 31) which consists predominantly of organic fibres and into a dust-grade fraction (33) which consists predominantly or organic dust particles.   <IMAGE>

Patent DE-3119831-A1 (DE)
Title: Hydraulic control device
Inventor: SANDAU HARTMUT ING GRAD
IPC: B60T13/14
Filed: 1981-05-19
Abstract: The hydraulic control device has a flow-control valve (16), a pilot-control valve (39, 42) connected downstream of the flow-control valve (16), an accumulator (33), and a brake valve (50). The brake valve is actuated by means of a control member (56), a control flow diverted from the flow-control valve being interrupted if the accumulator is not charged, whereupon the flow controller assumes such a position that the accumulator is charged. This therefore takes place only during a braking action. This ensures that this action is limited in time by the flow-control valve, if it is firmly choked, as a result of which overheating of the pressure medium is prevented. <IMAGE>

Title: Circuit arrangement for disconnecting the supply voltage when peripheral devices are not in use in telecommunications systems, in particular telephone systems
Inventor: HODES EDO ING GRAD
IPC: H04M19/08
Filed: 1981-06-13
Abstract: The circuit arrangement for disconnecting the supply voltage when peripheral devices are not in use in telecommunications systems, in particular telephone systems, comprises logic circuits (UG, OG) which activate a monostable flip-flop (MF). A switching means (S) connected thereto switches the supply voltage through to the peripheral device (PE) concerned if a command criterion is present on the data lines (BK) simultaneously with the presence of the relevant address on the address lines (ADR), and the monostable flip-flop (MF) is in its operating position due to the action of the logic gates. If no further occupancy criterion (BK) is present, the monostable flip-flop (MF) is not activated with the result that it reverts to its idle position after a definable time. The switching means (S) is controlled in such a way that it disconnects the supply voltage circuit of the peripheral device (PE). <IMAGE>
Patent DE-3123908-A1 (DE)
Title: Process for the chemical polishing of glass
Inventor: HORINA KARL-HEINZ DR ING
IPC: C03C15/02
Filed: 1981-06-16
Abstract: The mixtures of hydrofluoric acid and sulphuric acid used hitherto for the chemical polishing of glasses are adjusted in concentration so that the attack proceeds relatively slowly and hence glass material is removed fairly uniformly from the roughened and unroughened surface areas. According to the invention, compositions are selected which, as a consequence of much lower hydrofluoric acid concentrations, cause greater dissociation thereof, which means that the attack takes place more rapidly, but thus also in a more targeted way preferentially on the roughened surface parts. The advantages achieved are the lower acid consumption, reduced removal of glass with better retention of edges and peaks, a saving in time, and neutralisation sludge which is reduced in amount and in the CaF2:CaSO4 ratio.

Title: Control for breathing devices
Inventor: RAPP NORBERT JOSEF
IPC: A61M16/00
Filed: 1981-06-26
Abstract: The invention relates to a pneumatic control for breathing devices for assisted and controlled breathing of patients. The control contains a diaphragm which converts pressures into movements to which the windpipe of the patient is connected and to which two impact plates are attached which strike against one dynamic pressure jet each, which jets supply the control signal for a bistable pneumatic static switching element. The pressure coming from the dynamic pressure jet is fed directly into the actuation signal input z or y of the bistable switching element. With the subject of the invention an amplification of 1:10000 and a very high trigger sensitivity of -0.5 mbar is easily achieved without pneumatic amplifiers. <IMAGE>

Title: Hanging device on a letter file
Inventor: PFLUGFELDER THEODOR
IPC: B42F15/00
Filed: 1981-08-10
Abstract: Hanging devices for hanging up a letter file in a hanging cabinet by means of hanging members which are arranged on the rear cover and are displaceable in the longitudinal direction of the file back have the disadvantage that the hanging members located in the rest position are an obstruction when turning the document over onto the opened-out front cover, especially if the document has not been punched precisely. This disadvantage is avoided in that the part (41) of the hanging member, which is bent perpendicularly away from the outer front end of the longitudinally displaceable sliding parts (4) and has a length of at least a third of the width of the file back, has a greater spacing from the boundary of the back cover (1) on the file-back side than the inner edges of the document (B) turned over onto the front cover. <IMAGE>

Title: Method for attaching a strip-shaped brushing electrode
Inventor: PAPENDICK KLAUS
IPC: B03C3/41
Filed: 1981-09-29
Abstract: In the case of tensioning frames for brushing electrodes (spraying electrodes, emission electrodes), having a plurality of tensioning planes arranged above one another, the brushing electrodes have hitherto been fastened to the pipes situated on the inside in such a manner, that, for each fastening point, two through holes, laterally offset with respect to one another, were arranged through both pipe walls for the brushing electrodes pointing upwards and downwards respectively. The result of this is that it was not possible to achieve an optimum geometric arrangement of the brushing electrodes and that, owing to this type of fastening, optimum filter efficiency could not be achieved. To overcome this drawback it is now proposed that, on the pipes (6) situated inside, only one hole, which passes through both pipe walls in alignment, be provided for two brushing electrodes (1), extending in opposite directions, at a time, and that in each case two brushing electrode ends (4) are pushed into the holes from opposite directions and are joined to the tubes (6). <IMAGE>
