Patent SE-8100325-L (SE)
Inventor: INGANES OLLE WERNER
IPC: H01L21/312
Filed: 1981-01-21
Abstract: A method for coating a planar surface (5) of a semiconductor or insulator (3) with a polymer film according to a given pattern. The substrate to be coated constitutes one electrode (3) in an electrolytic cell whose electrolyte (2) contains monomers of said polymer. The substrate and the monomers are selected such that electrolytic oxidation or reduction occurs when a voltage is applied across the cell electrodes (3, 4) simultaneous with an area of the surface (5) to be coated being irradiated with radiation having energy larger than the energy gap between the valence band and conduction band of said substrate. The irradiation is performed with a sharply defined beam (10) simultaneous with a relative motion of said beam and the substrate surface (5) thereby making the polymer film of the desired pattern. The polymer, for example, is polypyrrole formed by electro-oxidation of a pyrrole monomer in an electrolytic solution containing pyrrole monomer and tetraethylammonium tetrafluoroborate in acetonitrile.

Abstract: Sheets for the dressing of walls, roofs, etc. are mounted at an early stage of building construction. Therefore, the jointing of the material must be so elastic that it can absorb the dimensional changes that arise due to uncontrollable climate changes before the building is completed. The joints must also be both strong and rigid in the completed building so that cracks and creases do not form in wallpaper or the like during normal seasonal moisture changes within the building.This invention provides a joint that fulfils the need of being very elastic in the beginning and later hardening. It can also be applied at any time and is heat insulating. The method is unique in that an elastomer-type glue is pressed into open joint crevices of a specific width in a specific manner and the glue has a low concrete content, whereby an elasticity-increasing cavity is formed as the glue dries.

Abstract: A filter rod making machine is provided with an apparatus for applying plasticizer to a band of fibrous filter material wherein the application rate of the plasticizer is independent of the filter tow weight or width of the band passing through the apparatus. The plasticizer is added to the underside of the moving band by means of a rotatively mounted brush in rotating communication with a plasticizer supply source wherein the amount of plasticizer added to the band is dependent upon the amount of plasticizer metered by a constant volume pump. The rotatively mounted brush delivers liquid plasticizer in the form of a spray to the underside of the moving band. Variable changes in the level of the liquid plasticizer in the reservoir varies the amount of plasticizer being presented to the band, maintaining constant absorption rate regardless of tow band width.

Abstract: A central control unit (scanner) is connected across a set of subscriber loops. At each subscriber's premises, an individual subscriber terminal unit (STU) is connected across that particular subscriber's loop. To each STU are connected the various instrumentalities which are to be monitored by the system, e.g. fire alarms, burglar alarms, etc. FSK modulated signals in the upper part of the audible range are transmitted from the scanner to the STUs at appropriate times. The STUs reply by means of similar signals to indicate the status (e.g. alarm, or non-alarm) of the instrumentalities at the respective subscriber premises. This transmission and retransmission is interrupted when the subscriber's telephone is off-hook. In addition, a signal below the audible range (low tone) is produced at the STU, and transmitted to the scanner over the telephone loop if, but only if, all the instrumentalities at the particular subscriber premises are in a given state (e.g. non-alarm). If not, low tone is stopped. Such stoppage is sensed by the scanner, and causes immediate transmission of the FSK signals from the scanner to the corresponding STU, even though the associated telephone is off-hook at the time. The reply to such transmission provides information about the reason for the stoppage, i.e. what is the source of the alarm.

Abstract: A stored program controlled real time system includes a high-speed executive processor (29) which receives real time signals coming from an equipment (2) and which coacts parallel-synchronously with two substantially identical reserve processors (30, 31). The processor each contain a plurality of function units (3, 5, 6) mutually connected by a data bus (19, 20). For indicating a faulty processor, the system includes a fault localizing means (32) which contains two comparators (34, 36), each of which has its two inputs connected to the data buses of the three processors and its outputs connected to three fault indicators (42, 44, 46) each assigned to a processor. The executive processor (29) updates the reserve processors (30, 31) by means of two data transfer channels (33, 35), the inputs of which are connected to the data bus (20) of the executive processor and the outputs of which are connected to the data bus (19) of the respective reserve processor. For compensating the time delays (/d2-d1/), /d3-d1/) forced by the channels in updating, a start pulse source (48) initiates the reserve processors with substantially equal time delays, in relation to the executive processor. The data transfer channels (33, 35) used for updating can also be used for fault localization, if the channel outputs are each connected to one of the inputs of each of the comparators (34, 36), the other inputs of which are directly connected each to a data bus (20) of the reserve processors. If the equipment (2) is not capable of reliably sending the real time signals to a reserve processor (31), the signals are transmitted via the executive processor (29) and via the respective data transfer channel (35) to this reserve processor (31) which lacks connection to the equipment.

Abstract: The invention consists in coating surfaces, which on occasion are in contact with concrete as it hardens, for example mould covers, concrete handling equipment etc., with a protective layer of plastic which has the property that concrete does not adhere to the plastic surface. The protective layer is made of a polymer pertaining to a certain group of polymers. This group is characterized by the fact that the polymer chains consist entirely or in large proportion - at least 30 per cent by weight - of an atomic group, which can be written: (I), where Qa, Qb and Qc each constitutes a single representive from the group hydrogen atoms, hydrocarbon groups and functional groups, but Qd constitutes a single representative only from the group alkyl groups. The most current ones in this group are polymetacrylates and polypropylene. The latter, especially, is highly suitable, owing to the fact that it is easy to produce thin films or fibres, respectively, thereof. The protective layer need not consist 100 % of a polymer according to the above definition but may consist of a mixture of such a polymer with another polymer compatible therewith, even one lacking the former's release capacity in respect of concrete as it hardens. The protective layer is applied to the surface to be protected by lacquering or by laminating with the aid of gluing or hot pressing. The protective layer, reinforced with fibres of the polymer type defined above, for example polypropylene fibres, is particularly wear-resistant.

Abstract: A method and apparatus for reducing energy consumption and minimizing martensite formations when joining a connecting piece of metal with a metal surface by pin brazing. The method comprises the steps of 1) measuring the exact amount of energy required to melt a particular brazing pin against a certain workpiece surface; 2) applying a welding current through the particular brazing pin and the certain workpiece surface to effect pin brazing; 3) calculating the amount of energy which has passed through the brazing pin during pin brazing by multiplying the square of the welding current times the duration of the welding current; 4) advancing the brazing pin automatically toward the workpiece surface during pin brazing so that the distance between the brazing pin and the workpiece remains constant while the welding current is being applied; 5) terminating the welding current when the calculation of the amount of energy which has passed through the particular brazing pin results in the exact amount of energy required to melt the particular pin; and 6) automatically interrupting the welding current if a predetermined period of time expires prior to termination of the welding current. An apparatus is provided for carrying out this method.

Abstract: The rotor is provided with an element, movable relatively to it, and preventing rotation, which in a first position relative to the rotor permits it only to be rotated from the first angle positon to an intermediate position between the first and second such positions. This rotation-preventing element is formed as an inertia mass which, under the effect of inertia forces, which act on the projectile during and after firing as the result of acceleration, is movable away from the first position relative to the rotor to one in which the rotor is free to complete its rotation to the second angle position. A securing component monitors the firing acceleration of the projectile on firing from the weapon barrel, and a drive unit, as the result of such monitoring, commences rotating the rotor from the first angle position.
