Title: Improvements in or relating to process for the manufacture of wall-paper
IPC: B41M3/18
Filed: 1930-08-18
Abstract: 368,218. Printing processes; impression surfaces. TAPANA, BEHRENS WERK-KUNST KOMMANDITGES., 53, Mertenstrasse, Hakenfelde, Spandau, Germany. Aug. 18, 1930, No. 24718. Convention date, Aug. 19, 1929. Void [Published under Sect. 91 of the Acts]. Drawings to Specification. [Class 100 (ii).] In a process for printing wallpaper, the first colour is applied in such a thin layer or is of such a consistency that a second colour can be applied directly without damage to the first colour layer. The colour can be prepared with a readily-volatile solvent or one which sinks rapidly into the paper. Colours are preferably used which are transparent when dry in order that combinations of shades can be obtained by overprinting. Graining and other effects can be produced by the use of an impression roller having an uneven surface so that the colour is not applied uniformly over the whole surface of the paper. The impression roller can be prepared by cutting a pattern thereon or by coating it with an adhesive and applying granular material such as rice, or fibres, paper figures, or friable materials. The colourapplying roller may also be roughened.

Title: Mechanical stage for microscopes
IPC: G02B21/26
Filed: 1959-07-20
Abstract: 881,222. Microscope stage. ZEISS-STIFTUNG, CARL, [trading as ZEISS, C. [Firm of]]. July 20, 1959 [Aug. 23, 1958], No. 24790/59. Class 97(1). A mechanical microscope stage particularly for micro-spectrophotometry is carried on at least one spring joint, torsion bar, or the like for rotation at least about one axis preferably parallel with the optical axis of the microscope objective. As. shown, the carrier 4 which rotates about the axis 6 on spring joints 3 can be given accurately controlled small amounts (approximately 1Á) of substantially linear backlash-free displacement in the direction 7 by means of an attached leaf-spring 8 which transmits, without the possibility of jamming, the movement of a lever 10, pivoted on the spring joint 9 for rotational movement about the axis 13, imparted by the screw control 15 against which the long arm 14 of the lever is urged by the spring 17. By turning knob 19, the arm 18 carrying spring 17 is brought into position 18<SP>1</SP> whereby the lever is brought to bear against a fixed adjustable stop 16 corresponding, for example, to a table position at which can be viewed a reference object some 200Á from the previous field of view. A similar arrangement could be used to provide motion in the direction 21 of a second carrier 5 mounted on the carrier 4, but this is more conveniently done by supporting the carrier 5 on pairs of leaf-springs 20, 20<SP>1</SP> so that a lever 23 actuated by a screw-control 25 causes a parallelogram-type motion whose downward component can be kept within the depth of focus of the microscope.

[Class 36] To facilitate location of an oil leakage in a three-phase oil-filled cable having insulated cores 2, Fig. 1, enclosed in a lead sheath 3 together with impermeable oil feeding channels 4, such as lead tubes, and permeable oil channels 5, such as tubes formed of perforated sheet metal, metallic net, or helically wound metal wire or tape, the cable is divided by stop joints 12, 14, 16 ..., Fig. 2, into sections consisting of two cable lengths connected together by an open joint, such as 11, 13, 15 ... , which allows free communication between the interior of the casing of the open joint and the permeable channels 5, and the sections are fed with oil through the impermeable channels, the arrangement being such that any three adjacent sections are fed from different permeable channels. The stop joints 12, 14, ... prevent the flow of oil from one section to another. A leakage of oil occurring at any point of the cable is indicated by an abnormal drop of the oil pressure in one of the impermeable channels 5 and the leakv section may be located from the end of the cable by employing the method described in Specification 369,119, [Group XXVIII], the impermeable channels 5 being treated as three separate single core cables for this purpose. The position of the leak in the section is determined by the same method and for this purpose the permeable channels of the section are connected to one of the impermeable channels passing through the stop joint at one end of the section.

Title: Improvements in process for the preparation of chlorhydrines
IPC: C07C29/66
Filed: 1935-09-09
Abstract: <PICT:0450372/IV/1> In the production of chlorhydrins from chlorine, olefines and water, the chlorine and olefine are separately absorbed in volumes of liquid adapted to their solubility, the circulation of this liquid being so controlled that a chlorine solution of at least 15 per cent of saturation is produced in the absence of any neutralizing agent, there being no discontinuity in the liquid circulation.  The reaction is effected in a tower 1 into which the olefine is introduced at 6 and distributed by a porous plate 2 or other means, and chlorine is introduced at 5 immediately before a pump 4 which circulates the solution through the tower 1 and side circuit 3, water being introduced at 8 and product withdrawn at 9. Inert gas escapes at 7.  In a modification, the liquid circulation may be in the opposite direction so that it flows downwardly in the tower 1 in countercurrent with the olefine.  Examples describe the production of ethylene chlorhydrin.  Specification 445,011 is referred to.

Title: Improvement in variable speed power transmissions
Inventor: DICKE ROBERT HENRY
IPC: F16H15/40
Filed: 1949-09-30
Abstract: 667,983. Variable - speed friction gear. DICKE, A. A., and DICKE, R. H. Sept. 30, 1949, No. 25108/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 31, 1950.] Class 80 (ii). A variable-speed friction gear, which may be automatically controlled in response to input or output torque, engine or output speed, throttle opening and/or intake manifold depression, for a motor vehicle, motor lawn-mower, mixer or drill press, comprises a free ball 3 contacting driving and driven discs 1, 2 arranged at an angle less than twice the angle of repose and with their axes 1a, 2a offset, so that the speedratio can be adjusted by axially sliding one of the discs to cause the ball to roll to different equilibrium positions between them. Thus, in any set position, the ball centre lies at the point of intersection of the following two lines ; one, NN, formed by the intersection of two planes N'N' and N<SP>2</SP>N<SP>2</SP>, parallel to the respective discs 1, 2 and spaced from them by the radius of the ball, and thus lying always parallel to the line XX of intersection of the planes of the discs and in the bisector plane MM of the dihedral angle included between them; the other, lz, 2z, joining the points of intersection 1z, 2z of the axes of the discs with the said bisector plane MM. Fig. 2 shows the one-to-one position with the ball 3 and line NN midway between the axes 1a, 2a, from which position axial adjustment of the disc 1 towards the disc 2 (dotted position, Fig. 1) causes the line NN to rise, and the ball centre to roll to a new equilibrium position on the line NN to the left of its Fig. 2 position, thus increasing the speed-ratio (disc 1 assumed driving) ; whilst axial withdrawal of the disc 1 has the opposite effect, a neutral standstill position being within the range of adjustment. In the practical embodiment, Fig. 7, not shown, the disc 1 is manually adjusted axially through an irreversible worm gear, turning a screwed bush supporting the disc, and the ball 3 is pressed by a spring-loaded roller towards the apex of the dihedral angle, to supplement gravity where the weight of the ball is insufficient to maintain contact. Drive. torque tends to force the discs apart and this is utilised in the automatically controlled forms, Figs. 9 and 10, not shown, in which the disc 1 is loaded axially by a spring so as to take up an axial position determined by the torque on the disc 1, single, or double inclined springs, or a single spring acting through a cam, being used to obtain any desired response, not necessarily linear. Reverse may be provided by an additional driven disc and ball on the opposite side of the drive axis, the two driven discs driving a common output shaft and means being provided to ensure that one disc is in neutral whilst the other is driving.

Abstract: 615,089. Change-speed gearing. BIRMING- HAM SMALL ARMS CO., Ltd., and FLETCHER, J. Aug. 24, 1946, No. 25348. [Class 80 (ii)] A vehicle change-speed gear giving a wide range of gear ratios comprises an epicyclic gear train mounted on a mainshaft 3 between freely mounted pinions 15, 17 meshing pinions 19, 21 respectively splined to a driven shaft 5. Planet pinions 29 engage a sun wheel 31 fixed to the shaft 3 and internal teeth on an annulus 33. Ratchet teeth 49 formed on the circumference of the annulus 33 are engaged by spring loaded pawls pivotally mounted on the casing 1, so that in the driving condition the annulus is held stationary, but may rotate in the opposite direction to facilitate free-wheeling. A chain connects sprockets 9, 11, secured to shafts 7, 3, respectively and a clutch (not shown) is incorporated between the shaft 7 and driving shaft 13. A sprocket 25 secured to the shaft 5 is chain connected to the vehicle wheels. As shown in the Figure, the gears are in the neutral position. To engage top gear, the pinion 15 is moved so that dog teeth 37 thereon engage internal dog teeth 39 on a sleeve 41 keyed to the shaft 3. On engagement of the gear teeth of the pinion 15 with adjacent internal dog teeth 35 on the planet carrier 27, the drive is transmitted through the sun wheel 31, planet pinions 29, planet carrier 27 and pinions 15, 19, thus effecting low gear condition. Similarly when the pinion 17 is clutched to the planet carrier by engagement of dog teeth 43 with teeth 45, the drive is transmitted through the epicyclic train and pinions 17, 21 giving a medium gear.

Abstract: 262,728. Germer, H. Dec. 10. 1925, [Convention date]. Embossing; holders for loose-type.-In a machine for making showcards &c. by cutting out and impressing coloured paper into a cardboard backing, the cutting and embossing type are held between strips f removably secured to a rectangular frame e resting on a die-plate a slidable on the bed d of the machine into position between the pressure members c, d of the machine, the latter of which is raised by eccentrics. The strips f which hold the type with their faces downwards are provided at their extremities with heads g grooved to fit over the side members of the frame e and secured thereto by set-screws, and the frame e may be square so that the strips can be arranged either transversely or longitudinally. To permit of the type being arranged in inclined lines, the strips f may nave a swivelling connection with their heads g. The side members of the frame e fit over the sides of the plate a and the cross members rest on the plate. When the plate a together with the frame e is moved by means of a handle n, from between the pressure members on to an extension d<1> of the bed d, the frame e is raised from the plate a to permit the cardboard &c. to be placed on the plate, by means of levers h pivoted at i and engaging the side members of the frame e. The levers are held in the raised position by means of a catch l which is turned to engage a bar m connecting the levers. To provide for embossing cards-which are longer than the plate a, the frame e is made longer than the plate and the embossing is done in sections. A part of the card is embossed, the plate a &c. is withdrawn on the extension d<1>, and the frame e with the cardboard &c. sticking to the type is moved over the plate a, the parts being then moved between the pressure members to complete the embossing. To ensure that the two embossings are spaced correctly, a tooth p is provided on the frame e for engagement with one of a series of recesses o in the handle n.

A hot top 5 for an ingot mould 1 comprises a lining 6 fixed within the upper inner end of the mould and a central unit 12. The lining 6 extends flush with the inner surface 2 of the mould. The central unit 12, which may be premoulded, moulded in situ, or constructed of tiles, converges upwardly from a shape closely corresponding to the cross-section of the mould and is preferably a sliding fit within the mould. Tiles 9 may be wedged into the recess in the mould wall or fixed by studs to the mould wall to form the lining 6. Ledges 16 are provided in the lining 6 to support the central unit 12. Alternatively, a frame 18 may be attached to the central unit. The hinged arms 21 of the frame fit over lugs 4 of the ingot mould and the frame not only supports the central unit but prevents it from rising on the surface of the melt during pouring. Weights or straps can also be used to stop the central unit from rising. When bottom pouring the melt, molten metal must not escape by the gap between the central unit 12 and the lining 6, so pouring is halted when the level of the melt in the mould reaches the lower edge of the central unit and the metal is allowed to solidify in the gap; pouring being then recommenced. To aid solidification of the melt in the gap a metal strip may be provided around the base of the central unit to act as a chill, or a granular substance that frits under the heat of the molten metal may be included above the gap.

Filed: 1922-09-23
Abstract: 187,950. Le Hardy, L. Oct. 27, 1921, [Convention date]. Cylinders receiving liquid fuel.- Fuel is injected from the chamber 14 by the shoulder 50 of the differential plunger 1, 2 which is forced upwards by the pressure within the combustion chamber after the opening of the mechanically operated valve 33, which allows the liquid trapped above the enlarged head 1 of the plunger to escape to the vessel 30. The fuel passes by way of the bore 37 to the chamber 38, whence it is injected into the combustion space through the annular slit formed between the head of the grooved screw 42 and the diaphragm 40 by distortion of the latter. The fuel is drawn into the space 14 on the downward stroke of the plunger through the concentric valve 17, which is held open at the bottom position of the plunger by the nut 26. The quantity of fuel injected may be controlled by rotating the plunger by means of the arm 25, and the sliding squared portion 7; by this means the plunger is screwed up or down in the nut 26 and thereby given a shorter or longer delivery stroke, which is always terminated by the contact of the head 1 with the shoulder 11.
