Patent FI-980890-A (FI)
Inventor: KOTAJA MATTI
IPC: E05D11/00
Filed: 1998-04-23
Abstract: In this publication, an automatic machine for applying a bolt hinge has been described, which automatic machine comprises an applicator head, on whose body 2 and drive axle 1 there is located a movable outer bushing 3, one end of which forms a rotating counter-stay 4 and to the other end of which a casing 5 is fixed by its supporting yokes 6 and springs 7. The feed motion of the applicator head has been positively controlled relative to the rotation speed of the applicator head and corresponds to a thread pitch of the bolt hinge to be applied. In the end phase of the application of the bolt hinge, the rotating counter-stay 4 brings to a halt the whole formed by the outer bushing 3, the casing 5 and supporting yokes 6 by means of a holding-down plate 8, whilst the whole formed by an inner axle 1 and the body 2 of the applicator head continues with a linear forward-running motion, the bolt hinge having room to be turned into the piece to be fitted therewith. Since the bolt hinge is mounted on the applicator head from the top of the bolt part and from the hinge body, the slight obliqueness of the bolt part in relation to the hinge body causes no functional disorders. The rotation speed of the hinge can be multiplied and the accuracy of application of the hinge can be improved. <IMAGE>

Title: Anti jamming radar device - uses electronic switch, e.g. cathode ray tube to determine phase relationships
IPC: G01S7/36
Filed: 1955-12-21
Granted: 1974-10-31
Abstract: An anti jamming radar device has the jamming signal, transposed into an intermediate frequency, applied to an electronic switch as a locking signal both directly and after having passed through a delay line which introduces a phase difference proportional to the frequency. The jammed echo signal, transposed into an intermediate frequency is also applied to the electronic switch and is passed or blocked according to whether or not a predetermined phase relationship exists between the two portions of the jamming signal applied to the switch. The electronic switch may be a cathode ray tube.

Title: Improvements relating to the production of lubricating oils
IPC: C10G67/04
Filed: 1962-01-12
Abstract: Lubricating oils with a viscosity index of at least 125 are prepared from petroleum feedstocks with a viscosity index of at least 90 by solvent extracting the feedstock to give a raffinate with a content of carbon in the form of aromatic rings of less than 5%, treating the raffinate so obtained in the presence of hydrogen and a hydrogenation catalyst at 200-800 DEG  F. and 1000-2000 p.s.i.g., and recovering a product having an increased viscosity index of at least 125.  This product may then be fractionated to remove lower-boiling material and dewaxed. Finally clay treatment of hydrofinishing may be carried out. The hydrocatalytic treatment may be effected in a single stage in the presence of a sulphur insensitive catalyst such as tungsten-nickel sulphide, or in two stages, first with a sulphur-insensitive catalyst to effect desulphurization, and then with a sulphur-sensitive catalyst.  The finished oil may have oxidation inhibitors added, for example, antimony diamyl dithiocarbamate blended with phenyl-a -naphthylamine or 5-ethyl-10, 10-diphenyl phenazasilane, or cadmium dithiocarbamate blended with phenyl-a -naphthylamine, or iminodibenzyl.

Abstract: 1382872 Thickness monitoring WESTON INSTRUMENTS Inc 12 Jan 1972 [12 Jan 1971] 1364/72 Heading G1A In a radiation gauge for monitoring the thickness of a moving flat sheet 10 employing two gauging units 11 and 12, comprising a base 17 containing an X-ray source and a head 14 containing a scintillation crystal with a photo-multiplier wherein the radiation beams 42, 36 are inclined in opposite directions to the vertical 37 as shown in Fig. 2B (showing an end view of one gauging unit); one gauging unit 11 remains stationary with its head 13 above the mid point of the sheet, while the other is shuttled back and forth transversely of the sheet by a chain mechanism Fig. 2A (not shown). Thus the gauging unit 12 shuttles into and out of a rested relationship with the gauging unit 11. The X-ray sources may each have standard thickness shutters which may be interposed in the beam path for calibration and automatic adjustment of the beam strength. The outputs of the detectors are amplified and compensated for temperature variations before being fed to respective meters which indicate any departures from the normal thickness of the strip. The signals may then be both fed to a differential amplifier which is connected to a meter or a recording device to provide an indication of the thickness variations across the sheet. A cooling fluid may be circulated through each gauging unit.

A machine for scouring, decarbonising, shot-peening, &c. comprises a centrifugal impeller and an injector for directing a stream of material against the impeller blades, the injector being eccentric and substantially parallel to the axis of rotation of the impeller and being carried by a support plate co-axial with the impeller and rotatable in an aperture in an impeller housing to be capable of rotation through 360 degrees relative to the housing, the injector being so carried by the support plate as to be capable of rotation through 360 degrees relative to the support plate to permit, irrespective of the angular position of the support plate relative to the housing, co-operation of the injector with a feed pipe for the material. The centrifugal impeller includes blades 2 secured between end plates 4 by grub screws 5, one end plate 4 being secured by bolts 6 to the driving shaft 3. The other end plate 4 has a circular aperture 9. The impeller is housed within a cover 11 including a bridge 12 and a discharge opening ; the cover and bridge are provided with projection plates 14, 15. A support plate 18 has a shoulder fitting into a circular aperture 16, concentric with the axis of the impeller, in the cover 11. The nozzle portion 22 of injector 8 projects through an aperture 23 in the plate 18, through an aperture in the protection plate 14 and into aperture 9. The injector is secured to the support plate 18 by bolts 19 extending through an annular flange 20 into topped holes in the support plate. An arcuate portion 24 of the injector includes a throat 25 of enlarged diameter in which can be located a feed pipe 26 from a supply reservoir. When it is desired that air assist in feeding material, air is introduced into the injector through the annular space between feed pipe 26 and throat 25. Where gravity only is employed for feed, the feed pipe is connected to the injector by a simple flange joint. In operation, the support plate 18 is rotated until the nozzle portion 22 of the injector is in the desired position eccentric of the impeller axis, ard the plate 18 is then locked in place. The arcuate portion 24 is then positioned to meet the feed line and is locked in place by the bolts 19.
