Patent SE-8102273-L (SE)
Inventor: WANLASS C L
IPC: H02K17/12
Filed: 1981-04-09
Abstract: In a polyphase machine, being either a motor or a generator, there is provided a stator core having main stator windings wound about the stator core and main windings having a capacitor connected in series with each winding of the core. Switches are provided for each winding, and a trigger source for the switches operates with the capacitor and windings to ensure sequential current flow in opposite directions across the windings. Variable frequency pulses from a trigger results in a variable speed machine. With control windings wound on the stator, oppositely to the main windings there are currents in each phase which are substantially in-phase at no load with the currents of the corresponding radially adjacent the main windings. Such currents become out of phase with their main winding currents as the load increases. At low load the net flux density is low and as the load increases the flux density increases. With the centers of the poles of the control windings placed as close as physically possible between the poles of the main windings, the magnetic centering of the poles is improved. The voltage across the capacitor added to the input voltage may cause the stator core to switch periodically between non-saturated and saturated conditions.

Abstract: One or both sides of a paper web 1 are coated by passage upwardly through a coating chamber 7, the coating substance picked up by the web being evened out in a coating nip 4 formed by a flexible blade 2 and a back-up member 3. The coating substance 16 is supplied by a duct 13 to the coating chamber 7 which has a narrow slot 5 at its lower end. The width of the slot 5 is adjusted, by means of an adjustment member 10, so that it is wider than the thickness of the web 1, and the speed of the web and the viscosity of the coating substance 16 are chosen so that little or no coating substance 16 flows downwardly through the slot. Any coating substance that does flow down through the slot 5 is collected in a container 12 for recycling to the coating chamber 7. In one side coating, the web may be supported by a roll 15 (Figure 3) or a plate 17 (Figure 5). <IMAGE>

Title: Frost protection method for ground-laid pipes - involves placing in trench insulating material drum containing filler to surround pipes
Inventor: SODERBERG RAMON
Filed: 1981-10-21
Abstract: The method is for laying pipes which are exposed to a risk of freezing since they are positioned at a depth in earth which is less than the frost-free depth. The method involves digging a trench to a depth determined by the thickness of the required cover layer. On the bottom of the trench is placed filler material which is spread out evenly. On the filler is positioned the under part of a drum of insulating material, this part having a U-shaped cross section and being composed longitudinally of consecutive sections. The under part is then filled with filler in which the pipes are laid. The trench is then filled in, pref. using the same material as that in the drum.

Abstract: An apparatus is disclosed for detecting small changes in the level of liquid (21) in a storage tank (20). The apparatus comprises a float means (38) floating at a desired depth (x) in the liquid (21). The float means (38) has a reservoir for holding a liquid measuring medium (19) and is movably connected to a support means (28). The support means (28) carries a source (32) for emitting electromagnetic radiation, e.g. light, and a detector means (36) arranged within the reservoir. The intensity of the radiation received by the detector means (36) is modulated according to changes in the location of the float means (38), i.e. according to changes in the level of liquid (21) in the storage tank (20). A method using this apparatus is disclosed for detecting leaks in liquid storage tanks by monitoring the signal representing the location of the float means.

Patent SE-8203217-L (SE)
Inventor: GUSTAFSSON P-A
IPC: F16C33/08
Filed: 1982-05-25
Abstract: The invention relates to a mounting comprising a sliding-contact or rolling-contact bearing bush which is pressed into a through-opening in a holding part and is secured by a press fit. In known mountings, the through-opening is finely machined during or after the production of the holding part to achieve the required fit for the press fitting of the bush. This is avoided according to the invention by the fact that the pressing surface between the bush and the through-opening opening is formed by the crests of a plurality of approximately axial ribs distributed circumferentially over the through-opening, which ribs are integrally formed on the inner wall of the through- opening and/or on the outer circumference of the bush. Due to the fact that the bush is not in full-surface contact when pressed in, deformation of the ribs occurs, compensating production inaccuracies in such a way that a firm and exact fit of the bush is obtained. By virtue of this compensating effect, finish-machining of the pressing surface between the bush and the location opening is unnecessary.

Filed: 1985-02-14
Abstract: The distance of an object is measured by using and measuring the time at which reflected waves 20b, 30b are detected. The waves are observed from the instant at which direct waves might possibly appear. If a wave is detected after the detection of a previous wave has ended, the measurement is repeated with a sensitivity updated to a higher level and, when the same wave is detected, this is considered as the reflected wave. If it is observed that the same waves are reflected by the same object with several different sensitivities, the value corresponding to the highest sensitivity is adopted. The transmitted level of the ultrasonic waves is regulated by using the mechanical properties of an ultrasonic transmitter through adjustments to the number of pulses or frequency of a binary signal which actuates the ultrasonic transmitter. If either the reflected waves or the direct waves are not detected at the predetermined time, the device is taken to be faulty. Application to the detection of objects from motor vehicles. <IMAGE>

Abstract: Method and apparatus for sterilizing or disinfecting objects, especially thermosensitive objects, in a closed chamber such as an autoclave. The use of such sterilizing or disinfecting takes place particularly in health institutions such as hospitals, outpatient departments, etc., as well as in the pharmaceutical industry. The sterilization or disinfection is carried in a strong oxidizing agent, which can be an organic peracid, advantageously peracetic acid in gaseous form. Sterilization or disinfection is carried out in a closed chamber, under a vacuum or at atmospheric pressure. Utilizing a vacuum increases concentration of the active agent in the chamber, so that the requisite sterilizing time is shortened. According to the procedure, the sterilization or disinfection is carried out at, e.g. 40 DEG  to 50 DEG  C. which also increases the concentration of the active agent, so that a short action time is achieved involving minimal thermal stress on the objects which are being sterilized or disinfected. The peracetic acid used in the method is completely environmentally protective and safe because it disintegrates rapidly into oxygen and harmless acetic acids.
