Title: Glass structural element for frameless mechanical fastening on a load-bearing structure
Inventor: KRAMER CARL PROF DR ING
IPC: E04F13/08
Filed: 1993-07-26
Abstract: The invention relates to a glass structural element for frameless mechanical fastening on a load-bearing structure. The glass structural element comprises a laminated glass unit (1) having two individual glass panes (4, 5) which are connected to one another via a plastic layer (6). The individual glass pane (4) directed towards the load-bearing structure exhibits at least one undercut bore (8) into which a fastening element is inserted. The fastening element is designed in a number of parts (individual parts 10, 10'), with the result that, with a suitable position of its individual parts with respect to one another, it can be inserted into the bore (8) which is open on one side. In their end position, the individual parts (10, 10') of the fastening element form a positively locking connection with the undercut of the bore (8). The individual parts (10, 10') of the fastening element exhibit extensions (15) which project beyond the surface of the glass pane (4) and are provided on the outer side with a thread (16). The individual parts (10, 10') are connected fixedly to one another by a ring (14) which is provided with an internal thread (14) and is screwed onto the extensions (15). <IMAGE>

Title: Fine pattern prodn with high resolution using simplified efficient method - by applying first photoresist, silylating and glassifying surface, making mask with second resist layer and etching down to substrate
Inventor: HAN WOO-SUNG
IPC: G03F7/09
Filed: 1993-09-16
Abstract: Prodn. of a fine pattern comprises the stages: (1) coating a process substrate (I) with photoresist (II) to form a first resist layer (III) and silylation of the surface to form a silylated layer (IV); (2) glassifying (V) with O2 to form a glassified layer (V); (3) coating (V) with (II) to form a second resist layer (VI); (4) selective exposure and development of (VI) in a given pattern; and (5) etching (V) and (III), using (VI) as mask. ADVANTAGE - Prod. of a fine pattern is simplified and the productivity is increased, since (V) is used as intermediate layer. The resolution is high. In an example, a Si wafer (1) was coated with chemically amplified resist (2). This was silylated in gas or aq. phase to form a 2000-3000 A thick silylation layer (21) and glassified with O2 (22) in RIE appts., forming a glassified layer (23) of SiOx in the organic material. A second resist layer (4) was applied, exposed with UV light (5) through a photomask (6) and developed. The glassified layer was etched with 100 Ncc O2/min at an energy of 2 kW, then the first resist was etched in 25Ncc CF4/min + 60 Ncc O2/min at 2kW in the same appts.
Patent DE-4335360-A1 (DE)
Inventor: SCHUETZ PETER
IPC: B01J25/00
Filed: 1993-10-16
Abstract: The invention relates to a moulded, activated fixed-bed Raney metal catalyst. The catalyst is obtained by moulding a powder of at least one catalyst alloy with a power of the pure catalyst metals with the addition of moulding aids and pore-forming materials and subsequent calcination at temperatures below 850 DEG C. During the calcination, the moulding aids and pore-forming materials burn. Alloy powder and metal powder sinter together in the course of this to give a mechanically stable and porous moulding. This moulding thus comprises the particles of the catalyst alloys which are bound by powder of the pure catalyst metals. It does not contain any catalytically inactive ceramic or vitreous binders. By leaching out the aluminium contained in the catalyst alloys using sodium hydroxide solution, the moulding is activated in a surface shell.

Title: Prodn. of imitation wood material from fibre materials - uses analysis of wood pore structure for pore cutting through CAD
Inventor: SENZANI GIOVANNA
IPC: B26F1/31
Filed: 1993-11-19
Abstract: To produce sheets from fibre material, with the pore structure to imitate natural wood, the required pore structure is analysed to give coordinate data for the pores as characteristic line points. The data are stored in an EDP logic unit with a computer aided design program to process the pore data and the pore dimensions. The data are converted into control signals for a computer controlled cutter to work the sheet or strip of fibre material, at the surface, with the pore pattern. The pore structure is cut into the material over its whole width, or a part width, evenly or in a pattern. Also claimed is an assembly with an analyser for the pattern to be reproduced as a wood appearance, and a system to store and reconstruct the pore structure in an EDP logic unit with a CAD program. The data are converted into control signals for a computer controlled cutter. USE/ADVANTAGE - The method is for the prodn. of an imitation wood sheet material, from a fibre materials, esp. for furniture veneers. The technique allows all types of wood pore structures to be reproduced faithfully to give an imitation wood material.

Title: Resonance inverter for driving R or RC or RL load
Inventor: RADECKER MATTHIAS DIPL ING
IPC: H02M7/537
Filed: 1994-01-25
Abstract: A resonant inverter has an LC-oscillatory circuit, a direct voltage source, an electronic switch and a control circuit. The last-named uses capacitors in a voltage-determining circuit which responds to the voltage drop across the switch relative to a voltage reference and a parallel resistance in a current-determining circuit which responds to  the current through the oscillatory circuit and/or the switch relative to a reference current. The current is determined at least during two separate time intervals in one cycle of the oscillatory current, and on the basis of the comparison of these two time intervals, the control circuit evaluates the value of the reference voltage used by the voltage-determining circuit.

Title: Method for the continuous casting of a metal billet
IPC: B22D11/22
Filed: 1994-05-20

Title: Heating-system controller
Inventor: ULRICH GERHARD H
IPC: F24D19/10
Filed: 1994-06-06
Abstract: The heating-system controller according to the invention possesses, in its memory (3), storage locations for a number of different daily heating profiles, for example 8, each of which comprise a certain number of switching times and the desired temperatures assigned to the intervals between the switching times. Located in a further part of the memory (3) are daily heating profiles assigned to calendar dates, whereby not the daily heating profile itself but only the respective profile type is stored. Consequently, for a relatively large period of time, e.g. a year, specific daily heating profiles geared to the diverse living habits of the user can be assigned to all days. Such a heating-system controller can be adapted to a very large degree and flexibly to possible user wishes, for example in respect of different requirements as a result of changing shift work and unusual alternation of workdays and work-free days. <IMAGE>

Inventor: OHSHITA MASAKAZU
IPC: B41J2/45
Filed: 1994-06-29
Abstract: A bit map unit (2) generates a bit map with the aid of predetermined image data, and a unit (74) detecting boundaries detects characteristic data of a boundary between a first and a second type of pixel which form the bit map. A determination unit (74) determines for each pixel whether a correction is necessary in order to make the image generated from the predetermined image data distinctly finer. A correction unit (75) carries out a correction to the image data for the pixel whose correction has been established as being necessary. A data reproduction unit (72) reproduces the predetermined image data which are to be used in the correction to be carried out by the correction unit. A unit (78) generates a time control within which the data reproduction unit carries out the reproduction operation. A unit (78) establishes the number of times that the data reproduction unit repeats the reproduction operation. A numbering unit (78) numbers the image data record which has been produced for each reproduction operation during the reproduction, in order to identify the number of each image data record produced during the reproduction. <IMAGE>
