IPC: G03F7/00
Filed: 1989-03-22
Abstract: A method of producing luminescent screens, enhancing or storage sheets for X-ray diagnosis, by X-ray irradiation of a metal plate (2) of a coated with polymethyl methacrylate (PMMA) (1) through X-ray mask (3) removing the irradiated PMMA to form honeycomb areas (7) which are galvanically plated with nickel to form a metal negative mold with Ni columns (11) and interstices (12). The interstices are filled with plastic and the plastic separated from the metal to form partitions (15), which are coated with a light reflective coating, and cavities (16) which are filled with luminescent substance (17) and a protective polyimide sheet (19) applied. Alternatively, a positive metal mold may be produced (Figs 6-11) or the irradiation can be carried out to produce an angular mould (Figs 13-14) <IMAGE>

Title: Combination of a sail which can be operated by one person in conjunction with a wind energy converter for the purpose of mounting on motor vessels in order to save burning fossil fuels
Inventor: HUSNIK FRANZ
IPC: F03D9/25
Filed: 1989-05-30
Abstract: The invention comprises a system for obtaining energy and saving fuel in an environmentally friendly way on ships, in order to start on a road which can be travelled with the aid of ecology and economy. It consists of a wind energy converter which is mounted with its shaft in a stable frame and runs with its foundation on double rollers in a roller guide. Two sails are pivotably mounted on this frame, and all sail manoeuvres are carried out by operation by one person with the aid of two electric carts which are mounted on sails 1 and 2. The sails themselves have stable frames which are additionally further stabilised by means of lattices. By adjusting favourable positions, the sails bring the wind energy converter to maximum output which it can convert very effectively into power by means of its four wind vanes in the cross configuration, two above, and two below. For the purpose of using all winds, the wind energy converter has two generators: the small generator is for light winds and by means of its continuous shaft connects a centrifugal clutch to the large generator. In the event of strong wind, the centrifugal clutch automatically switches the large generator thereto. The wind vanes are stabilised with three supporting inserts in each case and provide for trouble-free operation.

Patent DE-3934122-A1 (DE)
Inventor: NOCKEMANN OTTO
IPC: C05F17/00
Filed: 1989-10-12
Abstract: In known decomposition reactors, batches of unit loads which decompose only slowly, if at all, are stored. Highly charged waste water whose solids adhere to the large internal surfaces of the batches of unit loads and decompose aerobically in the insulated decomposition chamber with high self-heating are sprayed onto the batches of unit loads. The liquid which seeps through is collected and repeatedly sprayed onto the batches. The dissolved nutrients in the seepage liquid take part in the process as they seep slowly through the batches of unit loads and the seepage liquid is gradually purified. The process of the invention can be carried out so that decomposing materials are enriched with high amounts of decomposed solids from the waste water and similar quantities of biomass, or so that decomposing materials which are hard to wet are thoroughly moistened and excess moisturizing water is purified.

Title: Multi-level tool break detection using multi-mode sensing - senses cutting tool vibration signal which is processed using pattern recognition to detect high and low frequency transients
Inventor: THOMAS CHARLES EDMUNG
IPC: B23Q17/09
Filed: 1990-03-17
Abstract: Vibrations generated by interaction of a cutting tool and workpiece are sensed and a high frequency vibration signal with a frequency in a range between 30KHz and 100KHz is derived. At least one parameter related to force acting on the tool during a cutting process is sensed and a low frequency signal with a frequency less than about 1 KHz is produced. Each of the signals is preprocessed, sampled and digitised. The first and second tracking means signals are computed from a given number of previous samples. A pattern recognition device detects signal transients that may be caused by a tool break. An alarm determines that transients in the first and second mean signals are inclose time coincidence and occur in a designated time window, and generates a minor tool break alarm.

Title: Expanded seamless, thermoplastic, tubular film prodn. - directs air into prim. tube at die and tube acts as pressure tube as far as expansion stage
Inventor: HENNIG-CARDINAL VON WIDDERN MI
IPC: B29C48/10
Filed: 1990-04-20
Abstract: Process for prodn. of tubular film from thermoplastic tube and oriented in at least one direction. The tube is extruded from an annular die and the gas pressure for stretching the tubular film into a bubble enters the prim. tube through the annular die. The extruded prim. tube acts as pressure tube as far as the bubble inflation stage and directly after extrusion passes through a pressure chamber where external pressure prevents an increase in tube dia..  A cooling and calibration section immediately follows the pressure chamber and the tube is then reheated to a suitable temp. for expansion into a bubble. USE/ADVANTAGE - Process is used for prodn. of seamless, thermoplastic tubular film oriented in at least one direction, avoids bubble geometry variation and air loss leading to quality reduction.

Patent DE-4033037-A1 (DE)
Inventor: LUTZ EUGEN
IPC: B23D45/04
Filed: 1990-10-18
Abstract: 2.1. In known oscillating mitre saws, the cutting range is dependent upon the diameter of the saw blade. Apart from the space requirement, this can also have an adverse effect on the cutting accuracy. 2.2. In an oscillating mitre saw with a swivel arm whose swivel axis lies below the plane of the work rest of a saw table, it is proposed to design this swivel arm like a U-frame and to arrange it with its swivel axis in a vertical plane below the work rest, which vertical plane runs approximately through the centre of the work rest. Due this configuration, the stop and the workpiece are overlapped. The saw blade is guided like a trim saw. 2.3. Use for oscillating mitre saws. <IMAGE>

Patent DE-4037062-A1 (DE)
Title: Synchronisation method for async. data signal - deriving phase shifted auxiliary signals from sync. clock pulse signal
Inventor: WEHLAGE ERNST DIPL ING
IPC: H04L7/033
Filed: 1990-11-22
Abstract: In the synchronisation procedure the data signal is taken up by a flip-flop onto whose clock pulse input a sync. signal is applied. From the sync. clock pulse signal several phase-shifted auxiliary signals (EN1 - m) are derived by frequency division. The async. data signal logic levels are controlled by the derived auxiliary signals and taken up by several, level-controlled by the derived auxiliary signals and taken up by several, level-controlled flip-flops (2'-m). The logic level of signals at the outputs of the level-controlled flip-flops are cyclically taken up by a following flip-flop (14) whose flank is controlled by the sync. clock pulse signal. The phase position of the flip-flop output signals for the cyclic take-over of the logic level depends on the magnitude of a time flank offset. USE/ADVANTAGE - Flip-flop control, with prevention of metastable conditions. Uses only one flank of pulse and thus suitable for high pulse frequencies. External function corresponds to customary flank-controlled D-flip-flop.
