Title: Catalytic conversion of carbon monoxide-contg. gases - using extra scrubbing stage with weak aq. silica soln., to prevent formation of deposits on the catalyst
Inventor: GEIDIES ULRICH
IPC: C01B3/16
Filed: 1975-11-03
Abstract: A catalytic plant for converting CO-contg. gases with steam to increase their H2 content is equipped with a preceding humidifier and a following desiccator. Columns used either for humidifying or for drying are equipped with an extra plate ahead of the discharge for another scrubbing operation in which water with a Si content of 30 mg SiO2/l is used.

Title: Blow moulding of thermoplastic containers - with formation of handles and handle recesses in preform during blowing
Inventor: LAMPART DIETER
IPC: B29C49/04
Filed: 1976-03-31
Abstract: Prodn. of thermoplastic containers by blow moulding comprises surrounding a tubular preform with a blow mould in which it is blown by introducing a pressure medium, while simultaneously forming handle recesses and handles. Before introducing the preform into the mould, handles with welding lugs are formed from the preforme in a preliminary separate handle mould. These handles are placed in thrust cartridges belonging to the blow mould, and the cartridges are moved into the blow mould while the preform is introduced in its normal length and expanded. These steps are followed by closure of the blow mould, blowing of the container while welding on the handles, and cooling, while new handles for the next container are formed in the handle mould.

Title: Waste water purifier with two columns - has tall settling column connected a mid-height to shorter filter column
Inventor: RAUTH PHILIPP
IPC: E03F5/16
Filed: 1976-10-15
Abstract: The waste water purifier has two connected vessels forming three water columns. The water level is compensated by atmospheric pressure. The solids in the water are separated in a tall column automatically by gravity. One of two interconnected columns has double the height of the other one. A neutral one is formed by a connection between the mid height of the taller column and the top of the lower column. Lightweight particles move past this connection and heavy particles do not reach it. Additives are placed into the taller column for automatic separation of the materials. The shorter column has filters for the water in the neutral zone formed by the interconnection. This can be used as a central purifying plant.

Title: Directly fired incombustible granular material continuous dryer - incorporates hot air-dryer heated by continuous dryer waste heat
Inventor: LAMB ROBERT
IPC: E01C19/05
Filed: 1976-11-29
Abstract: The plant for drying incombustible granular material has a continuous drying section. The drying section is heated by combustion gases of an oil burner flowing in parallel with the granular material. This plant is used for firing bitumen or plastering materials and heat losses previously involved in meeting moisture contend fluctuations are eliminated. The material emerging from continuous flow dryer (2) is fed into a hot air dryer (13) whose hot air is obtained from a heat exchanger which heats ambient air by the still hot waste gases from the continuous flow dryer (2).

Title: Extruder for preparing and processing plasticisable material - has eccentric mounted kneader forming shear gap over whole surface
Inventor: BRAND WILHELM
IPC: B29C48/465
Filed: 1977-02-05
Abstract: An extruder for preparing or processing plastic or plasticisable masses, esp. for the moulding of synthetics or rubber, has a rotatable kneader. The kneader is assembled on an eccentric fitted to a driving shaft arranged concentrically in the housing, and having a guide for transmitting the drive in the housing wall. This consists of a pinion fixed on the eccentric and a stationary internally toothed crown wheel. The overlong stay of the material in the housing which results in decomposition and interaction, with reduced quality in the end product, is prevented by having the kneader travel the full distance round the keanding chamber.
Patent DE-2712002-A1 (DE)
Title: Tension monitor for overhead traction cables - has pivoted reel which operates safety cut=out and tension sensor including photoelectric device
Inventor: BEISEL KARL-HEINZ
IPC: B60M1/02
Filed: 1977-03-18
Abstract: The tensioning reel (5) for an overhead conductor rail has a pivoted support (12) which allows the reel to swing downwards when the tension is suddenly released. A safety cutout switch under the pivoted supports then switches off the overhead supply before the conductor has time to fall onto vehicles underneath. The tension sensor may include a photo transistor and a light gate to monitor the support position. The safety switch provides a rapid shut down of the current while a ratchet control on the reel stops the reel turning and winding in the broken supports.

Title: 1,4-Butane-diol prodn. by hydrogenolysis of maleic anhydride - or maleic or fumaric acids, over a mixed metal catalyst on silico-acetate carrier
Inventor: FREUDENBERGER DIETER DIPL CHEM
IPC: C07C29/17
Filed: 1977-04-07
Abstract: Prodn. of 1,4-butanediol (I) comprises hydrogenolysis of maleic anhydride, maleic acid and/or fumaric acid over a catalyst which is a mixt.of a Gp. 7b and a Gp. 8 Pt-metal (or their cpds.) supported on a silico-acetate, or its mixt. with silicic acid, as carrier. The carrier is made by treating a silicate, specifically of Mg, Ca, Zn, Ni, Co, Sr, Mn or Cd with acetic acid, and is then impregnated esp. with a soln. of Pt-metal acetate and perrheric acid in acetic acid, to give a compsn. contg. 0.1-50 wt. % active substances. (I) is an intermediate for poly(butylene terephthalate). The compsn. is resistant to abrasive losses in continuous processes; yield is imporved with reduction in by-products, specifically succinic acid, formation; and the catalyst has excellent resistance to O2-contg. gases.

Title: Shaped building blocks with rails for wall corners - comprises two movable parts, forming entity, with sealing wedges on one
Inventor: RANNOCH HERMANN
IPC: E04B2/12
Filed: 1977-04-18
Abstract: The shaped building block components, for masonry construction, have sealing wedges of elastic foamed material, for any format or materials, such as brick, concrete stone or sand-lime brick, to make structural corners at different angles. These are used in conjunction with flexible corner rails of various sizes, with supports for rendering. The corner shaped block is made up from two movable parts, forming a single entity, made individually or together, with sealing wedges on one of the parts. Grips may also be provided on the blocks. This enables corners to be built at varied angles, without involving a large number of different building blocks.

Title: Pleat-forming tape for curtains etc. - has inherent overall stiffness with stabilised drawn cords taken up in tubular zones
Inventor: DAHLMANN JULIUS
IPC: A47H13/16
Filed: 1977-06-29
Abstract: The tape (10) has draw cords (12) floating in alternating stretches along one side and has an uninterrupted constant stiffness which allows a more favourable handling of the tape so that when the latter is stitched onto the curtain it remains firm beneath the presser foot of the machine. The draw cords ared taken up in hollow tubular areas (11) which are formed from parts of the upper and lower fabric sections. These are stabilised by binding threads (15, 16) which connect the upper and lower fabrics (18, 19) together in relatively short intervals along the length of the tape. The stiffness of the tape can be achieved by working the same amt. of material in the warp and weft directions over the entire tape length in a continuous processing technique.

Title: 4-Methyl-2-pyrone-6-acetic acid ester(s) - prepd. by heating alkyl-3-alkoxy-3-methyl-acrylate or tri:alkyl ortho-acetate with acid catalyst
Inventor: SCHMIDT HANS-GEORG DIPL CHEM D
IPC: C07D309/38
Filed: 1977-07-29
Abstract: New esters are of formula (I); where R is straight chain, branched or cyclic hydrocarbon residue. (I) may be hydrolysed to give the corresp. free acid. Both (I) and the free acid are useful as intermediates for pharmaceuticals, insecticides and dyestuffs. The free acid is useful also as an intermediate for higher esters of formula (I). Specific cpds. (I) include that in which R is ethyl. In an example, this is prepd. in 90% yield by treating 50 g ethyl 1-ethoxy-beta-methyl-acrylate with 1.65 g BF3.2CH3CO2H and heating the mixture (with stirring) to 150 degrees.
