Patent FI-883403-A (FI)
Inventor: TORBUS MAREK
IPC: B22C1/20
Filed: 1988-07-18
Abstract: A coupling of multiple transmitters, which operate at different carrier frequencies, to a single antenna is often performed by multiplexing the output signals by means of a band-pass filter in the output frequency band. One end of the band-pass filter is connected to a starter network and thence to the antenna via an antenna feed line, and the second end is coupled to the transmitters via circulators. In order to make optimum use of the frequency band available, so as not to place such heavy demands on the band-pass filters, and in order to produce a dynamic channel arrangement, the transmitter coupling according to the invention has a first stage in the form of a digital coupling and a second stage in which the multiplexing is performed by means of band-pass filters. In the digital coupling the output signals of the transmitters are combined, in the grouping phase, by digital signal processing, advantageously by using the GTFM method. In the second stage the output signals are subjected in the parallel digital couplings to digital conversion in the group phase and to frequency conversion. <IMAGE>

Abstract: Process and arrangement for the manufacture of a skein of elongate unwound material, in which use is made of a spool 50, which has a conical spool core and a first detachable flange 53, which is arranged at the smaller diameter side of the conical spool core 52, and a second flange 54 at the other side of the spool core 52. The spool 50 is fixed in a spool arrangement by means of the spool holding members 103, 104, which centre the two flanges 53, 54 and are supported at the surfaces remote from the spool core 52. The elongate winding material D is then wound up on to the spool 50, the winding being controlled so that a predefined winding pattern is obtained. The skein is easy to transport, particularly when a plastic spool 50 is used, and at the same time is so solid that further packing measures may be dispensed with. In this way the occurrence of packing waste can be almost entirely avoided. <IMAGE>

Title: Process for obtaining earth metal compounds
IPC: C01F7/22
Filed: 1929-01-12
Abstract: 304,135. Krupp Grusonwerk Akt.- Ges., F. Jan. 14, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Chlorides; fluorides; aluminium halides; double salts.-Halogen or double halogen compounds of earth metals, for instance aluminium halides and cryolite, are produced and volatilized from raw materials by treating the latter admixed with fuel and in the presence of a halogencontaining reaction substance in a rotary tubular furnace, the whole or a large part of the necessary heat being provided by the gradual combustion of the added fuel, so that the reaction takes place in a long zone. Additional heat when required may be provided by flame heating in a way that the reaction for the most part takes place outside the zone of the flame. By co@@@@olling the temperature, quantity of fuel added, and the kind and quantity of the halogencontaining reaction substance, halogen compounds of different earth metals and heavy metals present may be separately formed and volatilized in successive operations. Air may be passed through the furnace in co-current with or countercurrent to the material. As halogen containing reaction substances, chlorides, for instance calcium chloride, fluorides, and free halogens are referred to, and salts used may, according to their character, be admixed with the raw material, or be introduced with the gases as a solid or molten salt or liquid brine. Volatilized halides may be condensed by cooling and electrical precipitation, or by wet washing of the gases; in the second case earth metal hydroxides are first filtered from the halide solution when the latter, after concentration if nencessary, may be re-used in the process.

Filed: 1976-01-13
Abstract: 1509831 Lasers COMPAGNIE GENERALE D'ELECTRICITE 13 Jan 1976 [15 Jan 1975] 1254/76 Heading H1C In a laser amplifying chain, particularly of CO2 lasers, comprising a generator 2 and at least two amplifiers 12, 20, radiation back reflected or reverse scattered into the chain where it is further amplified is prevented from reaching the laser generator by providng two crossed polarizers 6, 8 and a linear to circular polarization converter 10 between the generator and the first amplifier 12, and by providing two linear to circular polarization converters 14, 18 and a polarizer 16 crossed with the polarizer 8 between the two amplifiers 12, 20. To shorten the generated pulses a modulating Pockels cell 4 is included between the crossed polarizers 6 and 8. The linear to circular polarization converters each consist of a parallelepiped sodium chloride Fresnel element. On emerging from the final laser amplifier 20 of the chain the output is focused by a lens 22 on a target 24. The arrangement of polarizers and converters is such that any circularly polarized output reflected or scattered back from the target is vertically polarized by converter 18 and therefore suppressed by polarizer 16. If circularly polarized back-ward-directed radiation is produced in the final amplifier 20, this radiation is vertically polarized by converter 10 and then reflected forwardly from the converter surface nearest the generator for passage through the amplifier chain to the target. Backward-directed radiation of reverse circular polarization from amplifier 12 is similarly reversed in direction by converter 10.

Title: Improvements in and relating to fluid filtering, screening and like apparatus
IPC: B01D29/23
Filed: 1933-01-14
Abstract: 413,677. Filters. BRASSERT & CO., Ltd., H. A., and HOOKHAM, G., Brook House, Walbrook, London. Jan. 14, 1933, No. 1332. [Class 46.] In filters which are cleansed by a flow of fluid passing reversely through the filter body and discharged through a fitting which is reciprocated relatively to the filter body to traverse the whole of its effective area, the flow of cleansing fluid is automatically controlled in accordance with the amount of deposit on the filtering medium by a throttle valve or equivalent device on the outlet of the fitting. A cylindrical body b, Fig. 1, with perforations, in which discs of filtering-material are held by retaining rings, is arranged in a casing a having an inlet a<2> and outlet a<3>. There is a reverse flow of filtrate into a hollow annular member e with a peripheral opening e<5> and hollow arms e' through which impurities are washed into a hollow piston rod f, reciprocated by a piston f in a cylinder g. Liquid to move the piston f<4> is supplied to each end of the cylinder g alternately through a pipe a<7> from the outlet a<3> under the control of a slide valve h which also controls the connections from the ends of the cylinder g to an exhaust pipe i. The valve h is reciprocated by pistons h<1>, h<2> to which pressure is alternately communicated from the pipe a' under control of a pilot valve h<4>. The pilot valve is operated through a lever h<6> by a rod h<7> which is moved longitudinally by the member e as the latter reaches either end of its travel. The piston rod f telescopes over a tube g<1> through which the cleansing liquid is discharged and such discharge is regulated by a valve g<4> in accordance with the difference in pressure on the inlet and outlet sides of the filter body b. For this purpose the valve g<4> is connected by levers k, l, and rods l<3>, l<4> to pistons j<1>, j<2> in a cylinder j which is in communication through pipes j<3>, j<4> with the inlet a2 and outlet a3 respectively. The speed at which the member e reciprocates is controlled by a valve i<1> on the exhaust pipe i, this valve being operated by connections from pistons m<3>, m<4>, to which the pressures at the inlet a<2> and outlet a3 are communicated through pipes m<1>, m<2> respectively. Alternatively, if it is desired to move the members e at a uniform speed the pipes m<1>, m<2> are connected to the throat and mouth of a Venturi element or similar device in the pipe supplying liquid from the outlet a<3> to the cylinder g. Fig. 4 shows apparatus in which the member e is reciprocated from an electric motor 0<4> either by means of a screwed spindle q rotated by reduction gearing or by means of a rack and pinion device. The speed of the motor may be regulated by a rheostat in the motor circuit which is controlled in a similar manner to the valve i, Fig. 1. Reference is made to apparatus in which a filter body is reciprocated relatively to a stationary discharge fitting and to apparatus in which a cleansing-liquid discharge member is reciprocated over a plane filtering surface.

Title: Improvements relating to grinding machines
IPC: B24B41/04
Filed: 1954-01-18
Abstract: 746, 293. Grinding machine headstocks. FORTUNA-WERKE SPEZIALMASCHINENFABRIK AKT.-GES. Jan. 18, 1954 [Jan. 28, 1953], No. 1408/54. Class 60 A grinding machine has a headstock with a spring- loaded sleeve 13, Fig. 6, which co-operates with a spring- loaded tailstock sleeve to bring one end of a workpiece 7 into contact with an abutment 25 in order that each of a series of workpieces may be positioned in the same relationship with the grinding wheel, and a single operating member 48, Fig. 5, which actuates in succession a first means to prevent axial movement of the sleeve 13 in a direction away from the tailstock and a second means to relieve the workpiece from pressure by the abutment 25. The sleeve 13 is loaded by a spring 28 which may be adjusted by a screw 27, Fig. 4, and is mounted inside a hollow spindle 11 with which it is connected by a slot 14 and a screw 15. When the workpiece is mounted in the machine the sleeve 13 is displaced to the left by the pressure of the tailstock sleeve until the workpiece engages the abutment 25. The member 48, which consists of a lever pivoted to the headstock and provided with two dogs 46 to engage a groove 45 in a clamping sleeve 42, is then operated to cause an adjustable wedge member 51 to force a ball 41 into a recess between two members 33 which are thus urged apart against the resistance of a spring 34 so that they are firmly clamped against the interior of the spindle 11. Further movement of the sleeve 42 now causes one or more balls 39 to be depressed by a conical surface 49 into a tapered annular recess formed by a surface 36 on the clamped member 33 and a surface 32 on the member 11 so that the latter, is moved to the right by predetermined amount and the workpiece is supported by a centre 9 free of the abutment 25. The spindle 11 is rotated by a belt-driven pulley 17 provided with a work-driving mechanism 18, 19 and 20. A spring washer 21 and a spring ring 22 hold the centre 9 in the sleeve 13 which is provided with a sealing sleeve 23. The tailstock may be fluid or hand operated.

Filed: 1954-01-18
Abstract: 746,094. Turret lathes. NATIONAL ACME CO. Jan. 18, 1954 [Jan. 21, 1953], No. 1445/54. Class 83 (3). A lathe has a rotatable tool-turret 26, Fig. 2, with tool-slides 27, a cam-drum 17 to reciprocate the slides, a motor 79, Fig. 4, to rotate the turret, a drive-train interconnecting the motor and turret and including a clutch 75, 77, a worm 71, a Geneva gear 56 and a rotary arm 59 therefor, a motor 81 to operate the clutch, a switch 49, Fig. 2, actuated by the movement of the slides to control the motor 81, a locking-cam 63 rotatable with the arm 59, a lock-bolt 68 co-operating with the cam 63 and the turret 26, and a switch 84, Fig. 6, controlled by the rotation of the turret to operate the motor 81 to release the clutch 75, 77. The toolslides 27 are reciprocated from the drum 17 by a drawrod 30 having a collar 48 to actuate the switch 49 which, through a control circuit 97, energizes two solenoids 100, 102 to start an indexing operation. The solenoid 100 operates a valve 99 to disengage low- and high-speed clutches 103, 105 for the cam-drum 17, while the solenoid 102 operates a four-way valve 101 to release a clamp 37 on the turret 26 and to engage the worm 71 with the motor 79 through a clutch 75, 77. This worm rotates the arm 59 and the cam 63 to withdraw the locking-bolt 68 from engagement with the turret and to rotate the Geneva gear 56, and hence the turret 26, to new positions. A cam 85 on the same shaft as the cam 63 operates a switch 84 at the end of the indexing operation to de-energize the solenoid 102 causing the clamp 37 to re-engage the turret 26, and the clutch 75, 77 to engage a brake 74, 76 for the worm 71. Limitswitches 87, 94, operated by the locking-bolt 68 and the motor 81 respectively, ensure that the drive to the cam-drum 17 cannot be reengaged until indexing is complete. The turret may be indexed through more than one station at a time by screwing studs 91 into tapped holes 90 in an indexing-disc 53; the studs corresponding to the stations at which it is desired not to arrest the turret operate a switch 92 which overrides the switch 84.
