Patent SE-7802349-L (SE)
Inventor: ROBERTSSON H
IPC: G01S1/02
Filed: 1978-03-02
Abstract: Fan-shaped beams, sweeping angularly, substantially flatwise, across a solid angle space having the beam emitter at its apex, are modulated for transmission of special information to a selected one of a plurality of identically equipped bodies in that space. Whenever beam radiation reflected from a body is detected at the emitter, distance to the reflecting body is measured on the basis of radiation out-and-back time. If the body is at a distance for which special information is valid, the beam is modulated with such information for as long as its reflection from that body is received. A complete beam sweep cycle has a predetermined duration. As a basic condition for acceptance of special information, a body must receive such information on all beams during a predetermined time interval of at least that duration. As a further condition, a beam may be modulated with a characterizing sign whenever it intersects two bodies substantially simultaneously, and special information will be accepted at the body only if at least one beam lacks the characterizing sign.

The device comprises two parallel, separate straightedges 8, 9, and has a slit for introducing between the straightedges a foil of adhesive 10 with a width corresponding to a desired strip length. Between the straightedges, a movable punch 3 is arranged for separating from the foil 10 a strip having a width corresponding to the distance between the straightedges, and pressing the separated strip 16 against a cardboard cover 12 placed on the straightedges. The device further comprises means for pressing the cardboard cover against the straightedges 8, 9, simultaneously with the strip being pressed against said cardboard cover while transitory heating the strip 16. It is preferred that said means 11 for pressing the cardboard cover 12 against the straightedges 8, 9 comprises a heating device adapted to move in synchronism with the punch 3. <IMAGE>

Abstract: The invention provides improved stator windings for pole-amplitude modulation (P.A.M.) pole-changing electric motors and generators. In large machine of high pole-numbers, the effect of adjacent harmonics of m.m.f. waveform becomes evident in the form of low-frequency vibration of the frame. In small machines the effect, although present, is less important. The invention provides stator windings, particularly for large machines, wherein the phase-winding coil grouping, selected primarily for sinusoidal modulation, is selected secondarily to include a third-harmonic content, whereby the adjacent harmonic m.m.f. content may be reduced for both alternative pole-numbers.

Abstract: The objective comprises a plurality of movable lens components and at least one stationary lens component group, at least two of said components including an aspherical surface. The movable components are constituted by single lenses of which at least one lens comprises an aspherical surface, while the stationary lens component group(s) may comprise at least one aspherical surface. Steadiness of the image plane is obtained by mechanical compensation for focal-length variations with a ratio greater than five, which may readily reach the value eight. The aspherical lenses are arranged so that for the same focal length variation the total number of lenses of the objective, which may be spherical or non-spherical, is smaller than in any other variable-focus objective with a stationary image plane comprising solely spherical lenses: This results in a reduction of the mass of the objective, namely of the movable parts, and a reduction of the power necessary for moving said parts. Application to color television camera.

Abstract: A constant-tension spring device for the accessory belt of an automobile engine. The device includes a cylinder having an elastomer ring mounted within each of its ends. A rod passes through each elastomer ring, the rod having spaced shoulders each bearing against one end of a respective elastomer ring. Abutments within the cylinder position and retain the elastomer rings. Upon sufficient axial motion between the rod and cylinder, the elastomer rings are distorted by twisting and display a flat segment of the load vs. deflection curve between the rod and cylinder. The spring device maintains a desired tension within the accessory belt, compensating for temperature, humidity, and ageing changes in belt length which would otherwise result in change of belt tension.

Abstract: The intake valve has a hollow valve stem 18 and valve head 19 containing a vaporizable liquid. A heat exchanger 36 is provided at the end of the valve stem 18 to condense liquid which has been vaporized by heat transferred to the valve head 19. This ensures that the portion of the valve in the mixture intake system is maintained at a temperature which will prevent the transference of heat to the intake mixture charge from the valve and thus reduce heating of the charge. Wire mesh 34 acts as a wick to return condensed vapour to the head chamber 31. <IMAGE>

A cylinder (12) is incorporated, the pistion (11) of which is connected to the weapon recoil system, and the throttle passages are arranged between the cylinder spaces (15) on either side of the piston, e.g. in the piston. The control circuit (4-8) has the form of a regulating circuit incorporating an amplifier (6) controlling the unit by means of a theoretical value. The regulating circuit also incorporates outer and inner back couplings (7, 8) which send back signals (i1, i2) from an indicator monitoring a first parameter in the piston connecting rod, e.g. movement, position, acceleration, etc., and a second parameter from the medium thorugh the throttle passages (17), e.g. pressure, to coupling points (4, 5) in the circuit. The unit is arranged to effect controls (i3) with a frequency of 300 Hz or more.

Abstract: A scrub solution is made up for use in starting up a hafnium liquid-liquid extraction system. An aqueous zirconium oxychloride-containing solution is contacted with methyl isobutyl ketone containing less than 1 Molar thiocyanic acid. The aqueous solution is maintained at a chloride concentration of 1.6 to 3.5 Normal (as HCl) by addition of concentrated hydrochloric acid. Ammonium thiocyanate is added to the acidified aqueous stream to produce thiocyanic acid. The high acidity of the aqueous solution drives the thiocyanic acid into the methyl isobutyl ketone without the chloride anions having a depressing affect on the transfer. The thiocyanic acid-containing MIBK may then be used as a scrubbing solvent to start up the hafnium extraction system.
