Inventor: PAPENBURG ULRICH DIPL ING
IPC: C04B41/52
Filed: 1989-07-08
Abstract: High precision heating elements of carbon fibre-reinforced carbon (CFC) are produced by subjecting the porous carbon matrix of CFC heating elements, produced in any desired geometry by conventional shaping and carbonising processes, to chemical gas phase infiltration (CVI/CVD) with pyrolytic carbon, the infiltration amount or the CVI reaction time being controlled so that the density (1.1-2.0 g/cu.cm) and thus the heating cross-section or the resistivity can be previously adjusted by the decreasing porosity to the exact requisite value in the range 5-50 micro-ohms. ADVANTAGE - The heating elements are simple and efficient to produce and have extremely high temp. strength at up to 2400 deg.C in vacuum and/or protective gas atmos. have high stiffness, have ductile fracture propeties, have very good chemical resistance (esp. oxidn. resistance), have high wear resistance, have low wt. and have an extremely wide range of resistance values.

Title: New potassium-magnesium L-ascorbate-2-phosphate - recovered as stable, easily processed crystals from ascorbic acid phosphorylation mixt.
Inventor: DOBLER WALTER DR
IPC: C07F9/655
Filed: 1990-01-16
Abstract: K-Mg L-ascorbate-2-phosphate (I) is a new cpd. Pref., it has K:Mg atom ratio 1 +/- 0.3 : 1 +/- 0.15. The salt is prepd. by treating aq. soln. of K L-ascorbate-2-phosphate (III) with a medium-acidity cation exchanger which loses its exchange capacity at pH 2-0.5 to produce a soln. of mono-K salt. This is treated with MgO, Mg(OH)2 or MgCO3 to about pH7 and the soln. opt. treated with MeOH or acetone to ppte. (I). USE/ADVANTAGE - Conversion to (I) is used to recover L-ascorbic acid-2-phosphate (II) from phosphorylation mixt. It is produced free of inorganic salts; in well-crystallisation form which is easy to filter, non-hygroscopic and has little tendency to cake or form dust. The use of a medium-acidity resin produces an eluate which is not strongly acid (so does not decompose the product); MgO consumption and salt discharge are reduced, and regeneration times for the resin are Compared with ascorbic acid itself, (II) is more stable to oxygen, heat and hydrolysis, and has universal bioavailability.

Patent DE-4008719-A1 (DE)
Inventor: DIESING KARL-HEINZ
IPC: A22C21/00
Filed: 1990-03-19
Abstract: The invention relates to a method for the mechanical detachment of the meat from the carcasses of slaughtered poultry, in fillet form. The starting product is a "front half", i.e. a carcass section obtained by a transverse cut made obliquely through the poultry carcass, by which the pelvis with the legs and, in an additional stage, also the wings are separated off. Processing takes place in individual process steps, in the implementation of which only closely limited working areas can be traversed by tools which, consequently, are uncompromisingly adaptable to the anatomically determined conditions. Furthermore, the sequence of process steps is selected in such a manner that, with each working step, the increasing destabilisation of the poultry carcass is controlled in such a way that the respectively following working steps are impaired as little as possible. The result is a high yield of fillet meat of outstanding quality. <IMAGE>

IPC: A23G1/04
Filed: 1990-07-04
Abstract: In the continuous conching of chocolate mass in a conche (10) it is important to ensure essentially constant contents of the conche (10). For this purpose, the infeed of starting material and/or the discharge of the conched chocolate mass is monitored, namely measured, especially by means of weighing. In response to the measurement results, the infeed or the discharge is controlled, especially by means of altering the conveying capacity of a compulsory conveyor (screw conveyor 21) for discharging the conched mass. The conched chocolate mass is dry, i.e. it contains neither lecithin nor cocoa butter. Lecithin is added in the region of the screw conveyor (21) which is followed by a mixing device (22).

Title: Identifying power fluctuations in mains supply - preventing undesired release of remote protective circuit breakers from transient deviations by generating blocking signal from measured impedance values
Inventor: MACHOWSKI JAN PROF DR ING
IPC: H02H3/40

Title: Foamed panel mfr. - by engaging profiled edges of lower metal sheet with those of upper sheet by sliding in open press and simultaneously pouring foam onto lower sheet
Inventor: GUMPP MARTIN
IPC: B29C31/00
Filed: 1991-02-12
Abstract: A process and plant is claimed for mfg. a panel with thin metal faces and edges and containing an expanded foam. The long edges of both upper and lower sheets are shaped to enable them to interlock with each other. The upper sheet is initially located between the open press platens and one end is attached to the upper platen at the narrow entry end. A profiled tool supports the lower sheet and is used to push the lower sheet between the press platens such that the long edges of both upper and lower sheets engage in close contact with each other. While the lower sheet is pushed into the press, polymer foam is poured continuously onto the centre line of the lower sheet. After completely engaging the edges of both sheets the foam expands to fill the sheets between the now closed press platens. USE/ADVANTAGE - The process and appts. are used to mfr. foamed sandwich panels with metal facings combined with interlocking edges, simplifies the interlocking method and gives uniform foam density over the whole panel.
