Patent DE-3237510-A1 (DE)
Title: Polymerisation device
Inventor: KRANJC JOSEF
IPC: G02B6/42
Filed: 1982-10-09
Abstract: In known polymerisation devices, which use halogen lamps for generating a wavelength necessary for the polymerisation and are used for treating dental prosthesis parts in the mouth of the patient, screens must be provided for radiation protection and cooling arrangements must be provided for carrying off the heat; otherwise, the radiation efficiency is low and the polymerisation time is correspondingly long. The polymerisation device according to the invention avoids these disadvantages by using spectral lamps (1) which generate monochromatic radiation of the wavelength necessary for the polymerisation and focus the light at a spot in the inlet end (13) of a preferably flexible transmission facility (6) in such a way that the focus (B) lies within the inlet end (13). In addition, further means for focusing are provided at the outlet end (14). <IMAGE>

Inventor: MUSIN RAFAIL MUCHAMETOVIC
IPC: G01R23/00
Filed: 1982-11-03
Abstract: The invention relates to devices for frequency measuring and frequency spectrum analysers with devices for measuring non-linear distortions. The pulse parameter meter includes integral pulse converters (11...1n) with non-linear amplitude characteristics and an integral pulse converter (2) with linear amplitude characteristic and a system for processing the converted pulses with a subtraction circuit (4), band filters (251...25n), analog storage circuits (71...7n), a synchronisation unit (9), a channel switch (13), an analog/digital converter (15), a microprocessor (17) and a display device (20). As a result of the non-linear conversion of the input pulses and processing of the converted pulses with the aid of the microprocessor, the information on the most important parameters - the generalised amplitude, pulse duration, pulse area and energy, content of electricity of individual and repeatedly successive picosecond nanosecond and microsecond pulses is obtained. The invention can be used in high-frequency measuring devices. <IMAGE>

Patent DE-3302469-A1 (DE)
Title: Device for heat-treatment in the manufacture of concrete elements
Inventor: HOERNER JOHANN DIPL ING DR
IPC: B28B21/78
Filed: 1983-01-26
Abstract: The invention relates to a device for heat-treatment in the manufacture of hollow concrete elements, in which the cavities are formed by means of tubular mould pieces and which, in spite of different dimensions, are subjected to a mechanisable heat-treatment process with low installation and work outlay and with low energy loss. A tubular, cavity-forming mould piece, which is closed on one side and, on the other side, with closure plates of different sizes on the larger, has two sealable openings, through one of which a flexible steam supply pipe is introduced into the tubular cavity to approximately 200 mm in front of the closed sealing plate and in the other opening of which there is a condensate flow-off valve with a coupling piece for connection to a condensate drain. This steam flow, controlled in a pipe in one direction and flowing freely in the cavity in the opposite direction, ensures a uniform heating of the concrete moulded part across the casing of the tubular, cavity-forming mould piece, works with low energy loss and prevents, with the condensate flow-off valve open, an accumulation of air or steam.
Patent DE-3303400-A1 (DE)
Title: Method for producing ions from non-volatile substances by means of ultra-short current pulses
Inventor: FEIGL PETER DIPL PHYS
IPC: H01J49/10
Filed: 1983-02-02
Abstract: The invention relates to a novel, simple method for generating ions in a pulsed manner from non-volatile substances, for analysis in propagation-time mass spectrometers by rapid energy dissipation on the solid body surface. This is carried out by means of a very short current pulse which reaches around 100 A in a few nanoseconds, which current, in one mode of the method, flows on a thin wire on which the substance which is to be excited to form ions is applied. In another mode of the method of the invention, local initiation is achieved in such a manner that the current pulse is applied to a planar sample via a wire which can be moved relative to the sample surface, and is dissipated over said sample. The current pulse is caused by rapidly switching off a high voltage via a capacitor. The sample wire can, optionally, additionally be heated via an inductively protected DC source.

Patent DE-3312763-A1 (DE)
Title: Set of shelves
Inventor: ENGELMANN KLAUS
IPC: F16B12/42
Filed: 1983-04-09
Abstract: The set of shelves has compartment bases which are arranged one above the other and have push-in openings for separating bars in order to subdivide compartments. The ends of the separating bars, in alignment with one another, lie in the allocated push-in openings via a holding bush. The number of push-in openings of the set of shelves is small, since a push-in opening is only required for each two bar ends located opposite one another. The separating bars can be designed to be short, as a result of which considerable material and manufacturing costs are saved. In addition, simple assembly of the set of shelves is possible by means of the holding bush.

Patent DE-3339830-A1 (DE)
Title: Above-purlin laid heat-insulating layer for ventilated corrugated roofings
Inventor: ZIPP KLAUS
IPC: E04B7/22
Filed: 1983-11-01
Abstract: The invention relates to an above-purlin laid heat-insulating layer for ventilated corrugated roofings, comprising rows of elongated insulating boards of rigid plastic foam arranged next to one another, the end face of which boards runs parallel to the purlins. In the region of the end face (2) of two insulating boards (1 and 1') succeeding each other in a row, there is arranged on the upper side of the boards at least one clamp (4), which extends over the end face and is positively connected to each of the two insulating boards in the longitudinal direction of the boards. The formation of a joint in the region of the end face is essentially a consequence of a thermal expansion/contraction of the insulating boards, the contraction being greater than the expansion, so that an expansion/contraction cycle does not produce any reversible change in length of the insulating board. Due to the positive connection of two successive insulating boards carried out by the clamp at the end face, the contraction movement of the individual insulating boards is successfully prevented. <IMAGE>

Title: Method and apparatus for arc welding
Inventor: IVANNIKOV ALFRED V
IPC: B23K9/133
Filed: 1983-12-09
Abstract: The method involves forming the twisted consumable electrode (3) from several bare electrode wires (2) while the electrode (3) is being fed. This is ensured by twisting the wires (2) about the feed axis, during which the electrode (3) performs a revolving/advancing movement around and along the feed axis in such a way that each of the wires (2) of the formed electrode (3), which in the process has turned into a multi-start screw, enters the burning zone of the arc (7) at one and the same point. In the process, the feed rate of the electrode (3) into this zone is determined by its screw pitch, its rotary speed and the number of wires (2) forming it. The apparatus realising this method contains a welding torch (6) which is provided with a current-carrying end piece (5) and is connected to the feed mechanism (1) by means of a guide tube (4). The feed mechanism (1) contains gearing (16) and feed rollers (17) with a multi-start thread on the outer surface, which multi-start thread corresponds to the thread of the twisted electrode (3). The gearing (16) has two transmission ratios: one for the rotation of the rollers (17) about their axes in one and the same direction, and the other for the simultaneous rotation of the rollers (17) about the feed axis. The current-carrying end piece (5) is provided with a contact passage (49) having a screw surface which ... the thread of the twisted ... Original abstract incomplete. <IMAGE>

Title: Wax injection device for the production of wax models usable in fine casting
Inventor: KASTNER GERD
IPC: B29C67/24
Filed: 1984-01-27
Abstract: The device includes a heatable wax supply container (5) and a wax injection assembly (2), which essentially includes a wax injection cylinder (3) with a wax injection nozzle (4), and is also functionally connected via a piston rod (71) to an actuating cylinder (7) for the production of the required injection pressure. In order to facilitate processes of exchanging the wax supply container and also to reduce the set-up times during exchange of parts of the wax injection assembly, and to achieve a greater variability as regards the filling quantities, the wax supply container can be shut off with respect to the wax injection assembly with wax injection cylinder or wax injection nozzle and is constructed to be an assembly which is separable from these and is interchangeable, so that the wax supply container can be quickly replaced by a filled supply container which if necessary has been preheated. Thereby nozzle parts, in particular, can be exchanged and cleaned with a saving of time. The cleaning time can be reduced to about 1/8 of the cleaning times required for known integral assemblies. A shut-off member (51) at the lower end of the wax supply container is preferably provided, and is operated manually with a hand lever (52). <IMAGE>
