Patent SE-8104839-L (SE)
Title: Supplementary band in optical binary coded angle transmitter - has flanks between opaque and transparent areas in different position to those on main band representing lowest decimal value
Inventor: BERGKVIST L A
Filed: 1981-08-14
Abstract: The binary coded angle transmitter comprises a coded field with a number of parallel strips each with opaque and transparent/white areas, and representing a binary number in a series. The field is attached via a movable part in the angle transmitter, and a probe - comprising l.e.d.s and photo-transistors - is fixed in a housing in which the movable part is rotatably located. Parallel to the bands is a further one with the same division between opaque and transparent/white areas as that with the lowest decimal value or a tighter division than it. The extra band's flanks between the opaque and transparent/white areas differ in position from those corresponding in the lowest decimal value band. The field is read by probing the supplementary band's flank. (Provisional Basic advised week K14).

Abstract: For plastering walls having insulating boards, a first coat of plaster is initially applied to the insulating board and after a period of time in which the first coat of plaster is able to harden, a reinforced coat of plaster is applied. In this process, after the hardening of the first coat of plaster, a reinforcing fabric or the like is initially fixed on the surface of said coat by means of knifing filler, e.g. by means of a thin layer of mortar, and after solidification of the latter thereon, the second coat of plaster can be applied. If necessary, it is also possible to build up a relatively large number of layers in this way. Despite an unstable base, an outer coat of plaster is produced which avoids cracking and is nevertheless stable and which can provide good protection for the building element provided with insulating boards.

Abstract: An anti-theft device for clamping and locking an outboard motor to a transom board comprises a bracket forming together with an upper part of the outboard motor a substantially U-shaped suspension rack for mounting the outboard motor on the outboard transom side, and a free leg of the bracket extending downwardly along the inboard transom side. also included is a clamping fixture in the form of a jack screw including a hollow body and a clamping screw for urging the free leg away from the inboard side, while clamping the motor to the outboard side. The hollow body forms a protective housing having openings in its walls for receiving and shielding the screw shank, and supports at one end an open ended casing for receiving and shielding the screw head and a key-operated lock for locking the screw against rotation; the said housing and the casing are separated by a partition having an opening, and the screw shank extends from the casing into the housing through such opening. The screw shank is engaged in a threaded bore in the leg, whereby the screw, when rotated, urges the leg and thereby the motor forward and one base end of the body backwards against the inboard transom side, thereby clamping the motor firmly to the transom, and when the screw then is locked, the screw is non-rotatable, shielded and substantially inaccessible and thus safely protected.

Abstract: The time control is synchronised with the mains frequency, and the clock electronic circuits are driven from a source other than the mains, and from which energy is taken for adjustment of the tariff stage. Connection between the mains and the clock function controlling circuits is such that in the event of a break in mains supply, an oscillator circuit is connected which simulates the mains frequency. This circuit controls the clock function for the duration of the break, and the mains frequency condition is probed by a sensor which controls the function of an alternative circuit, to the one input of which the mains frequency is connected, and its other input is connected to the oscillator circuit.

Abstract: A method for installing a close-fitting cylindrical metal sleeve (26) within a tube (14) secured to a tube sheet (12) of a steam generator, comprising the following steps. First, the sleeve is inserted into the tube until an upper portion (28) of the sleeve is above the tube sheet while the lowr portion (30) of the sleeve is within the tube sheet. Next, the upper portion of the sleeve is radially deformed against the adjacent tube wall to form substantially coextensive permanent bulges (32,34) around the circumferences of the sleeve and the tube. The sleeve is then displaced axially, or longitudinally, relative to the tube, such that the bulge in the sleeve produces a wedge-like mechanical interference seal (40) against the tube wall (16'). Finally, the lower portion (30,38) of the sleeve is joined and sealed (42) against the adjacent tube wall (16') to permanently maintain the tight mechanical interference seal at the upper portion of the sleeve.

Abstract: Method and apparatus in the calendering of a web in a calender comprising a calender stack including at least two calender rolls situated substantially one over the other defining at least one calendering nip between them in which the web to be calendered is pressed at a suitable linear load, and wherein the outer rolls of the stack are provided with internal apparatus for varying or adjusting the roll crowns. The mantle of one or both of the calender rolls defining a calendering nip is heated to produce in the web passing through the nip a significant temperature differential in the thickness direction of the web between its interior portion and its surface layers and/or between its opposite surface layers. In this manner, the mechanical calendering work normally a function of the linear loading of the calender rolls is compensated for by the temperature gradient produced by the temperature differential which acts on the plastic properties of the web. The heating of the calender roll mantles is accomplished by external heating devices which at the same time adjust the axial profile of the calendering nip and the transverse thickness profile of the web by changing the radius of the roll through the variations in the temperature thereof.

Abstract: A leading edge of a web is fed to an upstream cutting station and is gripped at the cutting station with an upstream clamp which is then advanced downstream away from the cutting station to a middle station and is arrested in the middle station where the leading edge of the web is gripped with a downstream clamp and released from the upstream clamp. The leading edge held by the downstream clamp is then moved downstream to a holding station and the opened upstream clamp is moved along the web to a position slightly upstream of the upstream cutting station. The web is then gripped immediately downstream of the upstream cutting station with an upstream clamping conveyor and immediately upstream of the downstream holding station with a downstream clamping conveyor, and is gripped immediately upstream of the upstream cutting station with the upstream clamp. Finally the web is cut between the upstream clamp and the upstream clamping conveyor so as to cut the leading end off the web, leaving the cut-off end spanned between the upstream clamping conveyor and downstream clamping conveyor and forming a new leading edge of the web at the cutting station. The cut-off piece is conveyed away from the stations with the clamping conveyors.
