Patent SE-450396-B (SE)
Inventor: WESTLUND J O M
IPC: E04B/
Filed: 1985-11-13
Abstract: In a joining arrangement for construction elements, a first element 2 has at least one hook-shaped member 11 which projects from an elongate surface on the first element 2, and each hook-shaped member 11 is mounted displaceably from a folded-in position in the first element 2 to a folded-out position, and can also be drawn in towards the first element 2 and surround a locking pin in the second element 3 for pressing the first element 2 against the second element 3. By virtue of the fact that the second element 3 has an elongate groove, referred to as the main groove 7, which extends into the second element 3, in which at least one locking pin 7 is arranged displaceably in the longitudinal direction of this main groove 7, a joining arrangement for construction elements is obtained, in which the construction elements can be mounted adjacently to one another in optional positions along a given longitudinal direction, because the locking clamps 9 can be displaced along this longitudinal direction to settings which correspond to the settings or positions of the hook- shaped members 11.

Title: Stop device preventing opening of electrical switch box cover
Inventor: IGEFJORD M
IPC: H01H9/22
Filed: 1987-08-21
Abstract: The electrical switch box cover (5) operating component (6) has a recess (25) which in the closed position of the cover works in conjunction with at least one pin (24) on the operating shaft (23). On the inside of the cover, is a non-rotatable stop hook (81) with a stop surface (10) arranged in line with and turned towards the recess in the operating component when the latter adopts a turning position corresp. to the 'on' position of the switch. Accordingly, the operating shaft (23) pin (24), which is accommodated in the recess when the cover is closed, is arrested by the hook stop surface when an attempt is made to open the cover, and prevents the cover from being opened. The stop hook is sprung in its fixture to the cover inside, and via a hole (15) in the cover can be activated so that it moves against its spring force. This causes its stop surface to be brought out of its position in line with the recess in the operating component (6), whereby the operating shaft pin (24) can leave the recess unhindered, and the cover is openable even when the switch is in the 'on' position.
Patent SE-458787-B (SE)
Title: Machine comprising electrical generator and water turbine
Inventor: KENNETH HANS N
IPC: F03B13/10
Filed: 1987-12-03
Abstract: The water turbine (1) and the generator (2) are connected to each other by a shaft (3). The thus combined unit is supported by a floating bridge (4) located in a flowing water course so that the turbine is within a whirlpool (7). The generator feeds electricity to a user point (9) via a cable (8). The floating bridge has to be maintained above the whirlpool, and this is done by means of land-fastened lines (10, 11) or by a line (12) fastened to the bed of the water course. Pref. also the bridge should be attached to the bottom or to the water edge so that it can follow variations in water level. A further option is for the bridge to be supported yby columns arranged outside the central part of the whirlpool where the turbine wheel works. The whirlpool is created by a first unit located upstream of the turbine which conducts water flow (6) to a second unit (14) so shaped that it turns the current around the turbine wheel, causing the water to flow upwards.
Patent SE-459121-B (SE)
Title: Cooling tank for liquefying oxygen gas
Inventor: HALLBERG KARL
IPC: F25J1/02
Filed: 1988-01-18
Abstract: The cooling tank has bottom and top parts, pref. of steel. An intermediary part forms its walls. A bolt extends through the tank, and with the aid of a nut holds the tank parts together. Packings are fitted in the joints between the parts. To the tank cooling chamber is connected an inlet pipe, passing through the bottom part, for liq. helium, the pipe incorporating a check valve. The alloy used for the tank walls contains copper and gold in equal propertions, and the pipe circuit moulded into them has an inlet for oxygen gas, and an outlet for liq. oxygen. Liq. helium is fed into the cooling chamber at a temp. of approx. -272 deg. C. The liq. helium is gasified on entry into the chamber, and its feed volume is such that the pressure rises to approx. 20-25 atm. Under this pressure, the helium gas temp. rises to approx. -200 deg. C. Oxygen gas is fed into the pipe circuit, and because of the very good heat conducting characteristics of the wall alloy, heat is emitted as the gas is cooled to liq. form, and absorbed by the walls for emission into the atmosphere. The gas is continuously cooled, and on its passage outwards through the outlet in liq. form has a temp. several degrees lower than its boiling point, i.e., -183 deg. C.

Title: Contact nozzle having a helical passage for a welding rod and method for manufacturing such a nozzle
Inventor: NILSSON A
IPC: B23K9/24
Filed: 1988-10-28
Abstract: Contact nozzle for use in electric welding, having a helical passage 6 for a fusible welding rod 2. The nozzle 3 is realized such that there is good physical contact between the welding rod and the nozzle, at least over a specific section. The length of this section is sufficient to allow effective transmission of necessary welding current to the welding rod 2. In order to prevent over-powerful heating of the welding rod in the nozzle 3 with a risk of disturbances in the advancement of the rod, the nozzle 4 is electrically insulated 7 from the welding rod 2 apart from over the said section. The invention also relates to a method for manufacturing a nozzle according to the invention. <IMAGE>

Abstract: A multi-phase voltage-controlled PWM frequency converter, comprising at least one control unit (23), at least one rectifier bridge (20) designed to be connected to a multi-phase supply network (UU, UV, UW), a direct-voltage intermediate circuit and at least one controlled inverter bridge (21) for feeding at least one multi-phase load (22) with an alternating voltage (US, UR, UT) of varying magnitude and frequency. The inverter bridge has pulse width modulation-controlled semiconductor switches (V11-V16) and, in parallel with these, inverse-parallel connected diodes (D11-D16). The rectifier bridge has fully controllable semiconductor switches (V1-V6) and, in parallel with these, inverse-parallel connected diodes (D1-D6). The control unit controls the fully controllable semiconductor switches of the rectifier bridge in such manner that, in the upper arm, the switch of the phase concerned conducts substantially as long as the instantaneous value of the network phase voltage (UU, UV, UW) in question is the most positive, and in the lower arm the switch of the phase concerned conducts substantially as long as the instantaneous value of the network phase voltage (UU, UV, UW) in question is the most negative. The rectifier bridge (20) is connected to the inverter bridge (21) directly without a direct-voltage capacitor unit acting as an intermediate energy storage, and the direct current produced by the inverter bridge has been arranged to flow directly into the supply network without limitation of current peak value by an inductor unit.
