Patent DK-52884-A (DK)
Inventor: JOHANSEN ERIK
IPC: G01B/
Filed: 1984-02-07
Abstract: An optical measuring apparatus is specified with adjustment arrangements for projectors and mirrors or scales, where one can make the necessary adjustment by a simple turning of each wheel. Measurement of the individual angles, which are read off the graduated scales arranged on the projectors, can be done for both front wheels and rear wheels without turning the projector, because it is provided with a rotating mirror, so the light can be projected both forward and backward. The connection between the mirrors is arranged underneath the mirror's mount via an extension piece, so that large wheels can be measured. Because the light can be projected both forward and backward, and in conjunction with a zero-mark on the projectors, the alignment can be done in relation to the geometrical axis of the car in that one first adjusts the front wheels parallel with the rear wheels and establishes the angle of the rear wheels in relation to the perpendicular to the connections of the mirrors, after which the geometrical axis, which is the bisector of the combined rear wheel angle, is established, and the zero-point of the front wheels is then established from an angle in relation to the perpendicular to the mirror connecting line. <IMAGE>
Patent DK-90488-A (DK)
Inventor: CANONGE MICHEL
IPC: C07C67/03
Filed: 1988-02-22
Abstract: The invention relates to a process for the continuous preparation of acetates by a transesterification reaction in the homogeneous liquid phase in the presence of a catalyst selected from metallic alcoholates. The process comprises more particularly the introduction of the catalyst into a reactor (R) and the introduction of the reagents, formed by an acetate (I) and an alcohol (II), into a distillation column (D1) surmounting the reactor (R) and operating at a pressure (P1) identical with that in (R). The acetate (III) formed is withdrawn from (R) mixed with the catalyst, which is separated and recycled in (R). An azeotropic mixture (M1), comprising the acetate (I) and the alcohol (IV) formed, emergences at the head of (D1) and feeds a distillation column (D2) at a pressure (P2) lower than (P1), so as to produce at the head of the column an azeotropic mixture (M2) depleted in alcohol (IV), the mixture being recycled in (D1). The process permits the use of relatively humid reagents and alcohols of low reactivity, more particularly secondary alcohols.

Title: Improvements in or relating to protective means for machine tool or like guideways
IPC: B23Q11/08
Filed: 1936-01-02
Abstract: 467,346. Bearing covers. STEVENS, A. H. (Giddings & Lewis Machine Tool Co.) Jan. 2,1936, No. 142. [Class 12 (i)] [Also in Group XXII] Covers for machine-tool or like guideways are adapted to extend along and normally be in contact with the guideways, but are movable into spaced relation therewith substantially throughout the position occupied by a movable member or carriage on the guideways. A flexible steel strip 16, anchored at one end 17 of the machine lid 11, normally lies along the guide surface 13 of the bed, but throughout the length occupied by the movable slide member 22 the strip is spaced away from the lid passing through the slide under and over pairs of rollers arranged at each end of the slide member. Felt wipers 42, fed with lubricating oil from a reservoir 39 in the slide, supply the underside of the strip with oil to provide a seal and lubricate the guideway, the upper surface of the strip being cleaned by spring-pressed scrapers and felts before passing into the slide. The strip may be tightened by turning the roller 28 which is carried in adjustable bearings 33 at the end of the lid.

Title: Improvements in or relating to a process for the stiffening of slags upon liquid metal baths
IPC: C21C7/00
Filed: 1955-01-04
Abstract: A process for stiffening slags on liquid metal baths before pouring the metal comprises adding to the liquid slag a solid slag of the same composition.  The added slag may be that obtained from a previous heat and may be crushed to nut size.  Some of the slag may be poured off as a liquid and then the solid slag added at the outlet of the furnace thus forming a solid bridge which prevents the remainder of the slag being poured with the metal.

Title: Smokeless propellant powder and the process of making the same
IPC: C06B21/00
Filed: 1936-01-02
Abstract: Smokeless nitrocellulose powders are made in the form of globules by dissolving the powder in a solvent before or after its addition to a "vehicle" such as water with which the solvent is immiscible, agitating the vehicle with the dissolved powder so that globules of the dissolved powder are formed in the vehicle, and then heating the mass to evaporate the solvent.  The globules may be slightly porous and their surface may be treated with a deterrent such as dinitrotoluene, or an accelerator such as nitroglycerine, or with both deterrents and accelerators.

Abstract: 523,369. Domestic fireplaces. EMSCOTE FOUNDRY CO., Ltd., and HARVEY, F. Jan. 3, 1939, No. 180. [Class 126] The air entering below the firebars 13 is regulated by a loosely pivoted flap 18 formed on one side with a quadrant 20 having a scalloped edge enabling it to be secured in a set position by engagement with a lug 21 on one of the side members 10 to which the flap is pivoted. A projection 22 on the quadrant 20 limits the opening movement of the flap. In the closed position the flap fills the space between the upper edge of the front of the ash-tray 15 and the sill 14 of the grate. The front of the flap may be curved forwardly, thereby increasing the height of the opening available for the removal of ashes at the centre of the grate. The firebars may be arranged in accordance with Specification 523,368.

The radial extension 1b of the outer plate 1 embraces an angle α of 100 degrees, measured clockwise from the centre line 12 of the rollers 3, 4 and may be extended through a further anticlockwise angle # of 45 degrees, the part α having pressed axial ribs 1c at chain pitch spacing and being wide enough to support the full width of the chain. The side edge 1e is also turned out to produce a taper flange. The plain turned out edge 2b of the inner plate 2 spirals out from the roller axis 5, and is of a width to support only, the width of the chain between the chain links. The guide roller 3 has a lateral support extension 3b filling the space between the guide roller 3 and the plate 2. The two plates 1, 2 are connected together by the axis bolt 6 of the roller 4 and by a bolt 8 with spacer 9, the spindle bolt 5 of the guide roller 3 being secured at one end only to the plate 1.

Filed: 1977-01-06
Abstract: 1533822 Skips R E DIGGS 6 Jan 1977 409/77 Heading B8H [Also in Divisions E1 end B7] In an underwater mining installation empty skips are guided by wires 16 as they sink down on to springs 64 above a platform 22 located at the rear of a self propelled, submerged mining machine to receive mined mineral nodules from a conveyer 50 extending from the mining units of the machine rearwards through the machine. Compression of the springs 64 on the skip becoming fully loaded causes operation of a switching system that will stop the mining units, free the skip from the guidance wires 16, start up a conveyer 60 on to which the skip has settled as the springs have become compressed to cause the skip to be discharged rearwards clear of the machine down a ramp 66. When the skip is clear of the machine a collapsed buoyancy bag 69 housed in the top of the skip automatically inflates so that the skip rises to the surface.

A spring loaded compression member 13 is mounted on the housing 2 and acts on the middle of the anvil in a direction tangential to the anvil curvature to allow pivotable movement of the anvil away from the rotor without increasing the action of the compression member. Abutments 19, 20 on the housing engage the upstream and downstream ends of the anvil and are movable to allow adjustment of the working gap 18 between the rotor 4 which carriers the beaters and the anvil. The anvil 6 is formed as a grid of axial bars 7 and circumferential bars 8. The compression member comprises cup springs 15 prestressed by a threaded spindle 16 and a nut 17. The member 13 may alternatively comprise pneumatic or hydraulic springs.
