Title: Transport pallets of chipped raw material - laminated and additionally bonded by film forming material
Inventor: KISS GUENTER H
IPC: B65D19/00
Filed: 1976-07-06
Abstract: A pallet in one piece can be stacked and be subjected to high static and dynamic loading. It is produced in a single pressing operation from chipped, fibrous, powdered or granulated raw materials or secondary raw materials, alone or in combination, and provided with a bonding agent. The materials have a limited rising capacity and the supporting surface of the pallets is reinforced by a surrounding rim and a network of stiffening ribs, for pref. of full section. The amount of binder in the volume of the pallet is small - for pref. less than 1.5%. The supporting surface of the pallet is stressed by the surrounding rim, and the rim and/or the stiffening ribs of the supporting surface are of materials having a higher resistance to loading. The stressed plate forming the supporting surface of the pallet is pref. designed as a bonding plate. At least one surface of this is pref. of a material of higher resistance to loading than the basic material. Hollow ribs are easily damaged by the stacking forks, which results in the collapse of the pallet. Only the ribs touch the forks so that point loading only is achieved. The large amt. of binder normally used makes the pallets expensive but does not protect them against the weather and humidity. These deficiencies are all overcome without any increase in prodn. costs.
Patent DE-2633453-A1 (DE)
Title: Carrier frequency system without interference - has modulation filters and basic group filters with specified attenuation in stop bands
Inventor: GROTEMEYER PETER ING GRAD
IPC: H04J1/10
Filed: 1976-07-24
Abstract: The interference products in the basic groups of frequency range, when basic groups are formed or eliminated, are not produced. When group convertors stages are connected in cascade, attenuation of the sender or receiver side modulation filters of the lower stage convertors is 40 db below the level necessary for interference-free useful bands. In higher stage convertors the basic group filters are provided on the side facing convertors of the lower stage, whose pass band corresponds to the frequency range of the basic groups to be switched through, and of the groups between group convertors of the higher and lower stage. These basic group filters have a stop band attenuation of 40 db. The distance between the stop band and pass band is as wife as the minimu spacing between basic groups after their transposition to a higher group.

Title: Push-pull transistor inverter system - operates with trigger delay to prevent short circuits during switching operation
Inventor: PALZ GUENTER DIPL ING DR
IPC: H02M7/5387
Filed: 1976-10-22
Abstract: The power switching transistors (1-4) are controlled by signals from a pulse transformer (19) connected to the control unit (21). To prevent short circuits due to turning on an incoming transistor when the outgoing one is still in a conducting state during turn off signals are taken from current transformers (5-8) which prevent the incoming transistor from turning on when the outgoing one is still passing current. This is achieved by using the current signal to trigger a transistor (22, 25) and diode (23, 26) to short circuit part of the pulse transformer primary and thus prevent the transmission on of a turn on signal. The resistor (24, 27) in series with these logic transistors (22, 25) is chosen such that the voltage across, the part of the primary winding (20) is held to about 0.5 volt. Any pulse from the secondary windings (15-18) is then insufficient to turn on an incoming transistor.

Title: Double weave with ribbed air inlets - has short floating sections bonded against each other
Inventor: PENSLER ADOLF
IPC: D03D11/00
Filed: 1977-02-28
Abstract: The structure of a double-woven fabric incorporates permeable ribs to allow air to pass through for circulation. An additional weft is inserted between the upper and lower wefts to act as a weft tensioning system. The upper warps are bonded, forming a six-weave warp twill upper layer, with additional weft to form ribs in the upper fabric layer, and the lower warps are bonded with the lower weft to form similar ribs in the lower fabric level. The lower warps are drawn over the first upper weft and bonded under the first extra weft to pass over two lower wefts, run under the second tensioning weft and the second and third upper wefts to be bonded over the third tensioning weft. They then run under third and fourth, the lower wefts to bond over the fourth tensioning weft and run under the fourth weft, when the pattern is repeated. The other lower warps pass under the first upper weft to bond over a first tensioning weft, then run under two lower wefts, over a second tensioning weft and under the second upper weft, over the third upper weft to bond under the third tensioning weft, over the third and fourth lower wefts and under the fourth tensioning weft and the fourth upper weft, when the pattern is repeated. The use of tensioning wefts allows the development of short floating sections which are sharply defined and are bonded against each other.

Title: Eye tester using stimulating light - has brightness continuously varied according to mathematical function, contrast remains constant
Inventor: TAEUMER REINER DR
IPC: A61B5/0496
Filed: 1977-02-28
Abstract: Eye testing apparatus uses light to stimulate the eye or retina, and then obtain a graphical representation of the resulting signals. The brightness of the optical stimulator is continuously varied and the signals obtained are calculated according to a mathematical function, in dependence upon the brightness. The fixation light always has the same contrast against the background. Amplitude measurements are made at given time intervals, and the voltages resulting are indicated on a scale. The light source is intensity modulated by a signal by means of an optical/electronic converter to obtain a function signal. The original brightness signal is compared with the processed signal and a difference signal between maximum and minimum values is obtained and measured.

Title: Appts. for pyrolysis of hydrocarbon(s) - in which hydrocarbon supply is controlled to form hydrodynamic crater in molten heat carrier
Inventor: CHMELEVSKAJA GEB JASTREBOVA EL
IPC: B01J19/00
Filed: 1977-07-11
Abstract: Appts. for pyrolysis of hydrocarbons comprises a horizontally split casing contg. a molten heat carrier. Injector(s) for feeding a jet of hydrocarbons into the casing are mounted in an upper part of the casing so that the outlet of the injector nozzle is at, and directed towards, the surface of the heat carrier. Pyrolysis prods. are removed from an outlet in the upper part of the casing and heat is supplied directly to the heat carrier within the casing. The supply of hydrocarbons is controlled to provide a rate sufficient for the formation of a hydrodynamic crater in the heat carrier with a depth sufficient to ensure an intensive supply of heat to the prods. undergoing pyrolysis. Overheating of the casing material is avoided by supplying heat directly to the heat carrier.

Title: Protecting fibre bundles reinforcing hydraulic cement against ageing - by introducing between fibres liquid or pasty substance hindering penetration of water into bundle
Inventor: NEUSINGER HANNS DR ING
IPC: C03C25/1025
Filed: 1977-09-17
Abstract: Bundles of high-strength fibres having small breaking elongation, used for reinforcing hydraulically hardenable materials, such as cement anc concrete, are protected against aging to filling pores and capillaries in the bundle with a substance not hindering the mutual movements of the fibres, but hindering the penetration of water into the bundle. Pref. a hydrophotic substance, resistance to evapn. saponification, polymerisation, hardening, diffusion and/or emulsification is used. The consistency of this substance should be stable, it can be between low viscosity liquid and a soft plastic state. This substance is pref. a paraffin oil, a silicone oil or a silicone plastic. Reinforcing fibre bundles, pref. glass fibres (but other fibres e.g. carbon fibres, can be similarly treated) are protected against ageing resulting in decrease of the breaking strength and impact resistance. As the movements of the fibres within the bundle are not hindered by the impregnating substance, the stress can be distributed more evenly and the reinforcing effect is enchanced.
