Patent FI-973698-A (FI)
Inventor: MAEAETTAE ESA
IPC: A47C23/28
Filed: 1997-09-16
Abstract: This publication describes a coil spring construction especially for a bed mattress that conforms well to the body or a seat and a backrest in a chair. The object of the coil spring construction is to afford similar functional and springing characteristics to a typical water mattress, which is characterized in that outward pressure produced by the body on the mattress surface creates around it an uplift varying as a function of the pressure, the purpose of which uplift is to raise the mattress surface upwards to a degree that depends on the outward pressure at the point in question. The coil spring construction described in this publication returns completely to its predetermined rest position after loading. According to the invention, load members 4 have been fitted sufficiently closely into stuffed and flexible surfaces 1, 2 and 3, so that ends on the shafts of these form an underlay for the surfaces 1 and 2. By means of a draw band 6, the said load members 4 transmit the force produced by the outwards pressure and acting on the load members in the opposite direction, that is to say as lifting force for these said load members 4, through which the draw band 6 in question passes. Thus the surface 1 of the coil spring construction rises most at those points where the outwards pressure acting on the surface 1 is least. The object of the construction is largely to maintain the predetermined volume in the rest position, even under load. <IMAGE>

Filed: 1973-01-08
Abstract: 1388531 Detecting flaws NIPPON OIL & FATS CO Ltd 8 Jan 1973 [25 Feb 1972] 1018/73 Heading G1S A method of detecting flaws comprises the successive steps of coating a liquid penetrant containing a substantially colourless colour former on the surface of a material or article to be tested, removing excess penetrant, and coating on the surface a developer containing a colour reactant whereby chemical colour forming occurs in flaws present on the surface to produce a colour. The colour formers include indicators, complexing reagents, leuco dyes, oxines and diazo coupling- forming substances. An indicator is any substance which by its own colour or by some other easily observable property indicates the presence or absence of some other substance. Complexing reagents are broadly organic compounds, and leuco dyes are capable of yielding a colour upon being either reduced or oxidized. Many examples of colour formers and colour reactants are given.

Title: Process for obtaining kinematographic multi-colour photography
IPC: G03B33/00
Filed: 1926-01-14
Abstract: 246,154. Heide, E. Wolff-. Jan. 14, 1925, [Convention date]. Void [Published under Sect. 91 of the Act]. Colour kinematography.-In the production of kinematob aph multicolour pictures by the additive process, each of the separate partial pictures is coloured with more than one colour by special treatment of the transparent parts and the silvercontaining parts of the positive film. A negative film is first produced, divided into two series of partial images recording respectively (a) red, yellow, and blue-violet and (b) orange, yellowgreen, and blue, and a positive is printed therefrom. In the positive partial pictures, the blue and violet colours are represented by half-tones, and the remaining colours by transparent areas in their respective pictures. The colours may be applied to the positive in various ways. For example, the positive may be treated with a dilute iron blue bath, which imparts a blue colouration to the silver portions, and also differentially hardens the gelatin layer in these portion in proportion to its silver content. A colouring-bath such as pinatype yellow is then applied, which dyes the transparent parts yellow, and the silver-containing parts blue-green. The partial pictures on the film are additively superimposed by projection through a rotating colour disc, which alternately imparts violet and greenish-blue colours respectively to the red and to the green partial picture. The film may be differentially hardened by baths, other than iron blue, which do not colour the film blue; but in this case the blue colour must be contained in the rotating colour disc. This disc may be dispensed with if the pictures on the films are themselves coloured in the primary colours. For example, the positive may be treated as described above in an iron blue bath, and the red partial pictures be then treated in a bath which yields a red colour in the transparent portions and a redviolet colour in the silver-containing portions. The green-blue partial pictures may be similarly coloured. A modification is described in which the positive is resensitized with bichromate and differentially hardened by exposure to light before colouring; and a further modification is described in which the positive is first dyed with the primary colours, which are then mordanted, thereby producing differential hardening of the gelatin, whereafter the film is treated with a dye such as pinatype yellow.

Filed: 1940-01-19
Abstract: 539,744. Control of D.C. motors. PATE, G. Jan. 19, 1940, No. 1178. [Class 38 (iii)] A series motor A for hoisting &c. has a shunt field for preventing excessive speeds and a series field diverter for giving high speeds when lifting light loads, e.g. an empty hook. The first lifting notch of the controller includes so much resistance in the armature circuit that the motor will stall after slack rope has been taken up. The next notch includes a diverter across the armature to give a creeping speed. On the final notches, a load discriminator coil DIC is so connected that it places a diverter resistance SD across the series field if the load is low so as to give high speed. On all the lowering notches a diverter resistance is kept across the armature so as to give dynamic braking if the load begins to overhaul the motor. In the " off " position of the controller the both shunt and series fields are connected across the armature, and some resistance is inserted in series with the series field. On overload a relay OL opens the circuit of a contactor CON, and is reset by returning the controller to the off " position.

[Class 106 (ii)] A gauging device or template for testing the straightness or correctness of contour of metallic surfaces has its testing surface divided into a number of insulated segments each coupled electrically to a signal member such as a lamp for the purpose of indicating whether the several segments are in contact with the workpiece or not. As shown, a number of insulated segments 11 ... 16 are individually connected to a corresponding number of screws 37 and secured as a unit upon a sleeve 31. The unit, when required, may be attached to a stem 40 by a nut 41, the heads of the screws 37 abutting against heads 49 electrically connected by wires 47 and a multiple conductor cable 43, to a corresponding number of lamps arranged in parallel. The trueness of a cylindrical surface, for example, the cylindrical surface of a roller bearing may be tested by applying the surface of the roller bearing to the segments along a directrix, the places of contact and the departure from agreement being indicated by illumination or otherwise of the lamps. In a convenient assembly of the apparatus the segment unit is mounted upon a conducting plate along which the roller bearing is rolled into contact with the segments. In a modified device suitable for testing conical holes each segment is divided into insulated and diametrically-opposed halves the exterior surfaces of the assembly being of conical form. When the assembly is inserted into a conical hole in a conducting material, the opposed halves of the segments are bridged by the conducting material thereby completing the circuits of the correspond lamps, or the halves fail to complete the circuit thus leaving the lamps unilluminated.
