Title: Electrostatic precipitator - for gas purification with receding ionization stage
Inventor: FOELDI TIVADAR
IPC: B03C3/12
Filed: 1972-01-14
Abstract: The dirty air passes into a convergent tapered channel at the end of which is a circular outer electrode and a concentric spike inner electrode forming the ioniser and from which a divergent tapered channel leads to the main electrode system of the electrostatic dust precipitator. Near the ioniser is an ionisation level detector whose output is used to regulate the voltage applied to the ioniser electrodes. The ionising system enables the ion content of the purified air to be regulated to desired biologically safe levels.

Title: Yarn winding devices - associated with a single controller for winding predetermined yarn lengths
IPC: B65H61/00
Filed: 1972-04-08
Abstract: Yarn cross-winding devices associated with a common controller for winding predetermined lengths of yarns each include a yarn winding drum driving the bobbin and arranged as a pulse generator providing a number of signals proportional to the number of revolutions, the drums being drive independently and associated with yarn guide detectors, multi-stage selector switches and multi-stage ring counters interconnected with the selector switches and a common yarn length setting device controlling the selector switches of each drum. Gate circuits controlled by the output potential of the detectors apply the pulse generator outputs to the first stage of the ring counter such that when there is a coincidence between the value set in the selector switch and the count value in the ring counter the bobbin brake is applied in dependence on an emitted signal.

Patent DE-2342304-A1 (DE)
Title: Lightweight sports shoe manufacture - uses gripping pins for attachment of sole to completed uppers
Inventor: KERN HANS
IPC: A43D3/02
Filed: 1973-08-22
Abstract: The uppers of the sole are pulled over a last and then subsequently the sole is connected to the uppers. The toe section of the uppers has a marked curvature so that the lower edge which is folded back over the whole circumference of the shoe uppers is firmly placed over the underside of the last. The sole is directly attached to the folded over edge of the uppers. The last has projecting spikes at the tip of the toe and at the heel. These spikes grip the upper material at the point where the curvature is most difficult to produce. This method eliminates the more complicated method of mounting the uppers to the last.

Title: Plastic film disintegrator or shredder - with spiral blade cutter roll preceded by film draw rolls
Inventor: HEESS KARL
IPC: B29B17/04
Filed: 1973-08-30
Abstract: The further improvement to the appts. for cutting up plastic film disclosed in DT 2165509, whereby two draw rolls are provided between the two feed rolls and the cutter roll, and are driven in opposite directions at a higher peripheral speed than that of the feed rolls. In partic., the shafts of the pairs of feed and draw rolls and of the cutter and counter rolls are all parallel to each other. The improvement prevents the formation of strips of film of variable size and the loud noise caused by the intermittent cut of the straight blades on the cutter roll.

Patent DE-2351421-A1 (DE)
Inventor: HUMPHREY THOMAS D
IPC: G10G7/02
Filed: 1973-10-12
Abstract: An audible tone identifier comprises a transducer and amplifier for responding to audible tones, such as generated by a human voice speaking or singing, or a musical instrument, and a plurality of filters sharply tuned to the notes of one or more octaves or fractions thereof of the equal tempered chromatic musical scale or to other patterns of sounds that are to be individually identified. The outputs of the filters are connected to lamp driver circuits which in turn are connected through transposing plug-and-jack connectors and sharp-and-flat insertion switches to lamps on a display board, whereby any musical tone within the range of the device, received by the transducer, will be identified visually on the display board by the lighting of a lamp. The tone identifier may be a component of a teaching or speech therapy system including a source of recorded instructions and sounds to be produced by a trainee, such as a tape player and pre-recorded tape, and headphones through which the trainee hears instructions as well as the sounds produced by him. The relative conformity of tone frequencies with the center frequency of the filters is indicated by comparing the phase of said waves at the input and output of the filters.

Title: Fuel gas or synthesis gas prodn from coke-oven gas - by steam-reforming with ammonia stripper vapours
Inventor: TIPPMER KURT
IPC: C01B3/38
Filed: 1973-11-17
Abstract: Fuel gas or synthesis gas contg. CO is produced by (a) processing crude coke-oven gas in a water-cooling circuit to condense out the tar and saturate the gas with H2O vapour; (b) mixing the coke-oven gas with the vapours from an ammonia stripper used to strip NH3 from the excess coolant water; and (c) catalytically steam-reforming the mixt. in the presence of an O2-contg. gas, e.g. air, O2-enriched air or O2. The steam-reforming reaction is effected in a single step without coke formation, so that catalyst regeneration is avoided.

Patent DE-2405359-A1 (DE)
Title: Barking machine advance controller - uses difference of pulses from generators coupled to main drive and hydraulic advance drives
Inventor: REINHARDT PETER
IPC: H02P5/50
Filed: 1974-02-05
Abstract: Barking machine has a unit to establish the advance; the main drive is coupled to a pulse generator, whose pulses are conducted via a divider and form the controlling magnitudes for the advance drive(s) formed by hydraulic motors. Preferably the drives are coupled to pulse generators, and the difference of their pulses and those from the pulse generator of the main drive is fed as an analogue signal via a power amplifier, to form the input signal for the servo-valve controlling the advance drive. The controller allows fine steps of advance to be obtained and occupies little space.

Title: Oxidation/diffusion reactor for semiconductor wafers - with spiral gas inlet holes in inner tube around wafer rack
Inventor: GUECKEL HELMUT DIPL PHYS
IPC: C30B33/00
Filed: 1974-03-27
Abstract: In the parent patent a tubular reactor used for the oxidation and/or secondary diffusion of semiconductor wafers is surrounded on its periphery by a heater and houses in its interior a rack to accept the semiconductor wafers for treatment. In the patent of addn. the rack is arranged in a first tube which is partly surrounded by a second tube to which the process gas is admitted. Small holes are distributed near the rack in the wall of the smaller tube; the gas escapes through the open ends of the latter. This ensures that the concentration of the process gas does not vary, resulting in reproducible semiconductor wafers with oxide layers of uniform composition and thickness. The reactor is equally suitable for oxidation and for pass-through diffusion; it has a high capacity and the process is easily automated.

Title: Digital store system - for bidirectional transfer of data between two stores to different addresses
Inventor: NYSSENS PHILIPPE RENE GABRIEL
IPC: G06F12/04
Filed: 1974-06-25
Abstract: The store modules are arranged in words, and locations are individually addressable. Transfers are controlled by control lines to the two stores. Words pass along a data highway through a selection unit which can allow or inhibit parts of a word, or reorientate bytes before they are stored. The data highway must be one word wide. The main application is for transfers between a fast computer store and a slower larger backing-store or a scratch-pad store. Bytes need not thus be stored in the backing-store in the same word addresses as those in the computer store. Two or more words in the backing-store may be simultaneously addressable.

Title: Automatic erector for rolls of roofing felt - moves rolls from horizontal to vertical position using sloping plane table top
IPC: B65G47/252
Filed: 1974-09-14
Abstract: The appliance moves the rolls from a horizontal into a vertical position., and consists of a movable lower construction (3) with a table top (1). The table top is lowered, to form a sloping plane, in the direction of movement of the rolls (2), and moved back into a horizontal position when fully loaded. The lower construction may be moved to axial direction of the rolls, and into a depositing position. The construction is moved by a cylinder group, having a cylinder (4) with a high acceleration, and one cylinder (5) with dampened acceleration. Simultaneously, with the movement of the construction, the table with the rolls is moved by the cylinder into a pre-position. The table reaches its depositing position, only after the dampening position in a cylinder (6) is reached via the load build up of a cylinder.
