Patent DE-2554236-A1 (DE)
Title: Curtaining fabric handling equipment - having an intermediate bar to be positioned to increase length of material within fixed equipment dimensions
Inventor: HOFFMANN ERWIN
IPC: D06H1/00
Filed: 1975-12-03
Abstract: An appts. is claimed for handling long lengths of fabric, such as curtainings, for measurement, marking or cutting. The material is supported at the base and at an upper clamping beam of the equipment, together with an intermediate clamping bar which can be positioned at will in the vertical plane to increase the length of fabric between the base and the clamping bar.

Title: Dough roller with V:section trough formed between two belts - with rocker for mounting one of belt pulleys
Inventor: LIPPELT WILHELM BERNHARD
IPC: A21C7/01
Filed: 1975-12-22
Abstract: Dough rolling machine comprises a V-section trough consisting of a trough base and two endless belts which are supported in the trough by its side walls and move in opposite directions and at different linear speeds. One belt performs a movement which lifts the dough section in the lower region and presses it against the other belt. One of the rollers over which one belt runs is mounted in a rocker allowing it to pivot perpendicularly to the longitudinal direction of the belt. The belt can follow the lateral oblique upward sliding movements of a working beam without longitudinal stretching, and the two belt rollers are subject only to normal constant tension. Also, the working beam can extend over the whole free length of the trough wall between the rollers.

Title: Table-top horse racing game - has figures with engaging elements and drive units, moving in notched tracks
Inventor: REITZEL JOHN S
IPC: A63F9/14
Filed: 1976-08-21
Abstract: The horse racing game uses several moveable figures which are driven forward along individual parallel tracks. The tracks (26) are of similar length, each accommodates a figure (22), having engaging elements for the track, and extending at right angles to it. Drive units move along each track, to advance the figures. Each track has several evenly distributed notches, and the engaging elements are moved into and out of the notches. The elements are positioned in pairs on either side of a figure. The distance between these elements is larger than that between the notches, and different from a multiple of that distance. This prevents both elements from being at the deepest point of a notch at the same time.

Title: Short tube drawing plant with dies - uses mandrels for reduction passes and parallel runs of tubes in die series
Inventor: UHLMANN OTTO
IPC: B21C1/32
Filed: 1976-11-26
Abstract: The tubes of limited length are made by drawing successively through several dies. The reduction of cross section and dia. is achieved by floating mandrels for each die. The required drawing force is applied behind each die by a separate drawing element. Each tube length is provided with lubricant and the mandrel and pulled through the dies. A tube length is pulled to the succeeding die and inserted there. The tube length is held parallel to another tube length being drawn. After completion of the drawing process the tube length is moved together with the dies into the drawing plane and the drawing elements engage the tube length.

Title: Corrugated metal foils for thermal insulation - has crest against adjacent flat part to minimise contact area between insulation layers
IPC: F16L59/08
Filed: 1976-12-17
Abstract: The laminated thermal insulation can be applied to round or rectangular ducts and consists of several layers of corrugated metal foil (1). At regular distances, each foil is provided with a deformation in the form of two opposite half waves (3, 4). When the insulation foils (1) are installed around a duct, the crest of each wave is in contact with a flat section of the neighbouring foil. This method of assembly ensures that minimal foil contact is produced in order to prevent thermal conduction. It also produces air chambers between the foil layers, thus forming a barrier against heat transfer.

Title: Automatic continuous measurement of fluid ternary mixt. concentrations - using refractometer(s) with two different wavelengths and followed by evaluation
Inventor: WEINREICH PETER
IPC: G01N21/41
Filed: 1977-03-29
Abstract: The method is for automatic continuous measurement of three different fluids, e.g. a ternary mixture, and uses a refractometer with two different wavelengths. It is developed from the simple measurement method used for binary mixtures and employs two different wavelengths of light, a mathematical model, and derivation of the concentrations in a computer. One or two refractometers are operated with light of two wavelengths, e.g. 0.45 and 0.65 micrometers, to which the components exhibit different refractive indices. Current methods involve positive identification or summed identification and individual component subtraction.

Title: Advancing pit prop and mine roof covering system - uses lubricated zigzag folded plastics sheets, successively overlapped to guard against roof falls
Inventor: POLLER DIETER ING GRAD
IPC: E21F5/16
Filed: 1977-04-01
Abstract: An advancing pit prop system includes application of plastics, sheets to the roof as a protection against falls during operation. These sheets may be of polyethylene, and are folded in a zig-zag manner to form a bundle between 0.6 and 1 m thick. Each sheet is inserted between the top parts of the pit props so that it is overlapped with the free edge of a previously applied sheet. The pit props are then advanced, trapping the sheet, so that it is held in position. Lubricant can be applied between the sheets. Their thickness can be between 0.2 and 0.5 mm, their tear resistance is at least 15N/mm2 and elongation at least 4m/m or 400%. Alternatively, instead of a single sheet, two or three sheets, each 0.075 to 0.3 mm may be used on top of each other. A hygroscopic salt layer can be retained by the sheet.

Title: Fatty acid nitrile(s) and glycerol prodn. - by reacting mono, di, or tri:glyceride(s) with ammonia in liq. phase at elevated temp. in presence of catalyst
Inventor: BILLENSTEIN SIEGFRIED DIPL CHE
IPC: C07C31/22
Filed: 1977-08-20
Abstract: Fatty acid nitriles and glycerol are produced by reacting mono-, di- or triglycerides or their mixt., having the formula (I) (where R1, R2 and R3 are each satd. or unsatd. 3-23C hydrocarbon gps. opt. mono-substd. with OH) with ammonia in liquid phase in presence of a catalyst, at elevated temp. Process is improved by using as a catalyst a sulphonate (pref. an alkylarylsulphonate contg. 1-24C in the alkyl(s) and opt. up to two carboxyl gps.) or a carboxylate of Pb, Zn, Cd, Sn, Ti, Zr, Cr, Sb, Mn, Fe, Ni or Co. The temp. is pref. 220-240 degrees C until 30-70% of glycerol is removed; then the temp. is increased gradually or stepwise (over 0.5-5h) to 270-300 degrees C, and the reaction is completed at this temp. The reaction mixt. is then subjected to fractionation; the fatty acid amides are recycled, the fatty acid nitriles R1(R21R3)CN are sepd. from the aq. phase, from which glycerol is subsequently sepd. by the known methods. Method is esp. suitable for processing natural, vegetable or animal fats, but synthetic fats can also be used. The one-stage process is relatively inexpensive. High yields are obtd. (fatty acid nitriles =97% theor,; glycerol =95% theor). The process can be carried out continuously. The fatty acid nitriles can be converted into corresp. amines by hydrogenation.

Title: Lifting mixer - with axially reciprocating vertical paddle mixer shaft for lower power consumption
Inventor: RAEBIGER NORBERT DIPL ING
IPC: B01F11/00
Filed: 1977-11-29
Abstract: A lifting mixer for heat, mass transfer or mixing operations with or without chemical reactions consists of a paddle assembly on a vertical shaft in a mixing vessel which performs a periodical axial lifting motion. The blades of the paddles are inclined to the horizontal at an angle of 10-60 degrees (20-45 degrees) and their spacing on the axial shaft equals at least the amount of the lift. This impresses on the fluid a velocity with axial and radial components and combines a high mixing intensity with a much lower energy consumption, compared with conventional mixers.
