Patent DE-2618909-A1 (DE)
Title: Airfield or road de icing machine - has rotating roller cutter breaking ice coating into pieces and blowing or sweeping pieces away
Inventor: VIELHABEN KNUD DIPL ING
IPC: E01H5/12
Filed: 1976-04-27
Abstract: The process for de-icing aircraft landing fields, or other wide-surface traffic areas, involves cutting the ice layer into pieces and removing these by mechanical means. The ice layer can first be cut from the surface down to less than its full depth, and the pieces are then detached through the whole thickness and removed by blowing or sweeping. Cutting can be effected by a rotating cutter roller, with the depth of the incision determined by a sensor running on a section that is already de-iced; this can be a wheel, behind the roller and relatively height-adjustable.

Title: Hob nail for horseshoes - is made by welding head and shaft of different materials or properties together
Inventor: BIHLER OTTO
IPC: A01L7/10
Filed: 1976-07-21
Abstract: Hob nail for fitting horse-shoes is made of two parts welded together. Pref. the head and shaft are made of different iron or iron alloys suitable to the different requirements, the head being of tough, wear-resistant material and the shaft of more flexible material to allow bending around the hoof. To ensure a good welding joint, the nail head has a recess which is e.g. tapered and the shaft has a complementary shape for insertion into the recess, and the two are then welded together. Prior to welding, the distal end of the shaft is shaped, e.g. tapered, for good penetration through the hoof.
Patent DE-2633007-A1 (DE)
Title: Digital transmission error detection and synchronisation - uses ternary coded conversion generating comparison process status signal
Inventor: GILLESPIE JAMES ANTHONY
IPC: H04L1/24
Filed: 1976-07-22
Abstract: Multi-level coding of data in a digital information transmission system provides synchronisation correction and error detection. Blocks of received data are compared with stored values and the number of errors counted. When the number of errors exceeds a predetermined number a synchronisation process is initiated. Four bit binary words are converted to three-value characters. A pseudo-ternary coding based upon two alphabet characters are used. A regenerator processes the three value coded words to supply positive or negative values to a serial to parallel register. A block sum detector operates on the three characters and delivers values of -3, -2, -1, 0, 1, 2, 3. The values are added to stored values and the result stored in a status word memory. A counting system tracks the number of errors generated.

Title: Dialkyl malonate prodn. from sulphuryl diisocyanate and ketene - by conversion to sulphuryl diazetidindione and direct alcoholysis
Inventor: FUCHS RUDOLF DR
IPC: C07C67/18
Filed: 1976-07-31
Abstract: Dialkyl malonate (I) prodn. involves reacting sulphuryl diisocyanate (II) with ketene in the presence of inert organic solvent (III) at -10 to +30 degrees C and converting the resulting sulphuryl diazetidin-2,4-dione (IV), without isolation, to the corresp. (I) by alcoholysis at +30 to +150 degrees C. In an example ketene was passed into a soln. of (II) in 1,2-dichloroethane at +10 degrees C and the mixt. was refluxed with EtOH contg. dissolved HCl. 97-99% pure (I) was obtd. in 87% yield. The amts. used in the first stage are 2.05-2.5 mole ketene/mole (II) and a (II)/(III) wt. ratio of 1:10-20. (III) is a low mol. chlorohydrocarbon. In the second stage, the alcohol/(IV) molar ratio is 5-20:1 and a non-oxidising mineral acid is used as catalyst. Good yields are obtd., even at temps. above 0 degrees C.

Title: Meat slices tenderising system - using eccentric press for meat compression in dies between plastic foils for sealed bags
Inventor: KUORTTI VAEINOE
IPC: A22C7/00
Filed: 1976-08-27
Abstract: Slices of meat, cut across the muscle fibres, are tenderised by passing the slice between the two platens of an eccentric press. The meat is enclosed during the compression between two plastic foils which are welded together to form a sealed package when the slide has been pressed to a 'Schnitzel'. This replaces the mutual labour of beating the 15 mm thick slices down to the 3 to 5 mm thick 'Schnitzel'. Excessive extra costs by oversize 'Schnitzel' are saved.

Title: Watercraft propulsion system using wind energy - has sail-like surfaces to trap wind and direct pressure to eject air underwater
Inventor: BIESTERFELDT HARALD
IPC: B63H9/04

Title: Coating printing machine parts with strippable ink-repellent lacquer - based on vinyl! chloride copolymer, minimising cleaning on changing ink
Inventor: REICHOW KLAUS
IPC: B41N3/00
Filed: 1977-05-12
Abstract: A plastics coating is sprayed or brushed onto printing machine surface areas coming into contact with (various flexographic) printing inks, e.g. ink troughs, overflow tanks, pumps and pipes. The coating consists of a strippable lacquer with high strength and low gas, vapour and liquid permeability, which is partic. resistant to the ink and its solvent, repels the ink and allows any adhering ink residues to be washed off (with water) before the ink is changed. It makes time consuming and troublesome cleaning of these areas largely superfluous. The coating pref. is coloured, so that flaws are readily discernible. The lacquer consists of 5-25 (15)(wt.)% vinyl chloride copolymer (with vinyl acetate), 1-2% plasticiser, 1-3% antiadhesive agent and 70-93% organic solvent (aromatics, ketones and/or esters). solns. in EtOAc with a viscosity of 65 plus-or-minus 10 cP at 20 degrees C or in 1:1 acetone/toluene with a viscosity of 110 plus-or-minus 10 cP are pref.

Title: Gas filter backflushing system - with pivoted nozzle arm opening compressed air value and sealing clean gas outlets
Inventor: HOELTER HEINZ
IPC: B01D46/00
Filed: 1977-06-25
Abstract: A backflushing system for gas filters includes a power cylinder which is actuated by the rise in resistance of the filter element. It moves a hinged flushing air tube which contacts the valve on an air receiver and opens it. Nozzles on the air tube enter the clean gas outlets of the filter, seal them and produce a backflushing burst of air. The lower flow resistance of the elements restores the initial position. This is a simple backflushing method and requires a min. of space.
