Patent SE-7710672-L (SE)
Inventor: SHEEHAN J C
IPC: A61P31/04
Filed: 1977-09-23
Abstract: In accordance with this invention, it has been found that oxygen analogs of 6.beta.-aminopenicillanic acid and biologically active derivatives thereof can be formed from esters of 6-oxo-penicillanic acid.  For example, 6.beta.-phenoxyacetoxypenicillanic acid - an oxygen analog of penicillin V may be formed from an ester of 6-oxopenicillanate.  The ester of 6-oxopenicillanic acid is formed by a diiospropyl carbodiimide/dimethyl sulfoxide oxidation of the corresponding ester of 6.alpha.-hydroxypenicillanic acid. The oxygen analogs are formed by reducing the ester of 6-oxo-penicillanic acid to the corresponding 6.beta.-hydroxypenicillanate and then forming the desired analog by acylation.

Abstract: An electromechanical clutch for vehicle engine cooling fans includes a driving member mounted for rotation by the vehicle engine and a driven member rotatably mounted on the driving member. The driven member carries the engine cooling fan. One end of a metal band is connected to the driven member, and wraps circumferentially around the driving member in the direction of rotation of the latter. An electromagnetic coil comprising windings wound circumferentially around the driving member and rotatable therewith exert an electromagnetic force on the band when current is transmitted to the coil, drawing the band into engagement with the outer circumferential surface of the driving member, to thereby engage the clutch and cause the engine cooling fan to be rotated with the driving member. Because of the wrapping effect of the band when it engages the outer circumferential surface of the driving member, the electromagnetic force necessary to actuate the clutch is multiplied as the clutch is engaged through the servo action caused by the band wrapping around the driving member. The electrical signal is transmitted to the coil through a slip ring, and is controlled by conventional engine temperature and/or pressure sensors.

Abstract: An equalizing network for attenuation/frequency characteristic equalization. The equalizing network comprises a plurality of attenuation branches B1 to B8 which are operative in mutually different frequency sub-bands covering a wide frequency band. A negative feedback amplifier 10 has its negative feedback factor set for each frequency sub-band by means of a potentiometer P1 to P8 which is part of the relevant attenuation branch. Resistors 17, 18, 19 and 20 form the negative feedback circuit for the amplifier 10 and provide voltage-dividing, to alter the feedback factor and thus the gain of the amplifier 10, for the individual frequency sub-bands as determined by the potentiometer settings. Attenuation branches pertaining to non-adjacent frequency sub-bands are grouped together in two groups X and Y to obviate the need for separation amplifiers for each attenuation branch.

Abstract: Packing containers of the non-returnable type which are manufactured from flexible laminate material usually have sealing fins (3) which extend over one or more walls (2) of the packing container. In parallelepipedic packing containers, moreover, triangular corner lugs (4) are present over which the sealing fins (3) extend. In the final shaping of the packing container the corner lugs (4) are folded down and fixed against the side walls (2). This is made more difficult, however, as the sealing fins (3) have to be double-folded which because of their thickness and stiffness brings about deformations and stretching which cause damage to the packing material, so that it no longer remains liquid-tight and gas-tight. 
<??>This is avoided in accordande with the invention by folding different portions of the sealing fin (3) in different directions so that the folding down of the corner lugs (4) can take place without the thickness of the sealing fin having a hindering effect. As a result the impermeability to liquid and air of the finished packing container is appreciably improved, and this is very important in the packaging of e.g. liquid foods.

Abstract: Measuring a DC or a low frequency AC current by feeding the current to be measured through the primary winding of a transformer, whereby a first flux is generated in the transformer and generating a modulating voltage and also phase shifting the modulating voltage. The phase shifted modulated voltage is applied across the secondary winding of the transformer with an amplitude so as to saturate the core. The phase difference between the modulating voltage and the phase shifted modulating voltage is monitored while feeding a compensating current of increasing amplitude through the secondary winding until the phase difference is zero. The amplitude of the compensating current at zero phase difference is a representation of the current to be measured.

Date Feb. 28, 1985.Seat plate (10) for supporting the pelvis of a person sitting in a seat (2), e.g. a seat in a vehicle. Known seat implementations only give limited support in a horizontal direction. This causes a noticeable problem in vehicle seats, since a person sitting on one is subjected to accelerations and retardations in both longitudinal and transverse directions. The muscles which are activated in such cases become tired relatively quickly, often resulting in that an incorrect sitting attitude is assumed which can give rise to skew loads as well as accelerating and amplifying the sense of tiredness and soreness. The invention relates to a seat plate (10) for positioning the pelvis of a sitting person so that no notable muscular work is required for maintaiing a correct sitting attitude. The seat plate (10) is thus formed with two raised, scythe-like ridges (11) each including a forward transverse ridge portion (13) and a longitudinal ridge portion (14) extending backwords from the transverse portion (13). Valleys (16), formed between the ridge portions (13,14), position both seat bone protutuberances of the pelvis against gliding forwards as well as laterally.

After a predetermined time the reduced pressure is removed and the mold and container are tilted back into the starting position. The mold and container are then separated again and the mold is then heated for completion of the jelling or curing whereupon the mold is cooled for removing the work piece from the mold.

Abstract: The invention relates to an optical amplification device (10) with noise filter function. A body, composed of a plurality of layers (11-15) of different materials has electrodes (16) on its opposing sides. A first (12) and a second (14) of these layers is light wave conductive and forms a directional coupler with an interaction length (2L) consisting of two coupling lengths. The other (14) of the light wave conductive layers is a travelling wave amplifier which is pumped by an electric current (I) between the electrodes (16). The dispersion of the light wave conductors varies according to different relationships, and the effective refractive index has a common value (Neff0) for the wavelength intended for amplification. A light signal (Is, Ib) in the first waveguide (12) migrates transversely over to the second waveguide (14), where it is amplified and migrates back again to the first waveguide (12). At the same time there is noise filtration of the signal (Is, Ib) by a passband covering said wavelength. The noise filtered away is absorbed in the end portion (l2) of the second waveguide (14), and by the light being coupled in transversely in this waveguide the amplification device (19) will be free from reflection.
