Title: Improvements in Processes for Bonding or Uniting Articles particularly the Parts of Vacuum Insulated Vessels.
IPC: A47J41/02
Filed: 1919-06-02
Abstract: 127,824. Mantle Lamp Co., (Assignees of Simonson, W. W., and Blair, L.van D.). June 1, 1918, [Convention date]. Drawings to Specification. Resinous compounds; varnishes.-A fusible adhesive jointing compound for uniting parts of glass, metal, or fibre is prepared from lac or shellac. In some cases. a metallic substitution derivative may be used. Instead of lac an organic equivalent thereof may be similarly employed. The joint is subjected to a heat treatment to convert the compound into a hardened product having a higher fusion temperature than the initial compound. The material is applicable especially for uniting the inner wall of a vacuuminsulated vessel to the outer wall. Shellac is freed from fatty and waxy substances by dissolving it in a warm weak solution of caustic soda, the impurities being removed after cooling of the solution, which is then clarified by the addition of an agent such as powdered kaolin. The metal constituent of the final compound may be lead, calcium, barium, zinc, or other metal. In the case of a lead compound, a clarified solution of the shellac-sodium compound is mixed with lead acetate and a sufficient quantity of water to produce a flaky precipitate, which is dried. The compound may be used in the form of a gasket placed between the parts to be united, or may be applied as a solution in alcohol or acetone. The whole is then heated to fuse the compound, without, however, causing the glass or other parts to fuse. Preferably the parts are heated to a temperature above that at which fusion of the compound takes place, but the parts may be subjected to a prolonged heat treatment in an oven at the temperature of fusion. A shellac-lead compound may be mixed with a wax-free shellac obtained by treating the shellac-sodium compound with hydrochloric or other acid, the mixture being applied in the same way as the lead compound. The temperature of fusion may be varied by altering the proportions, or by employing one metal in place of another, or in some cases a non-metallic shellac compound may be used. Powdered charcoal may be added to the compound to prevent bubbling. The Specification as open to inspection under Sect. 91 (3) (a) states also that metal or other substances may be rendered air-tight by applying thereto a coating of the alcohol or acetone solution of the compound and subjecting it to heat treatment. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in printing rollers for fabrics and the like
IPC: B41F13/10
Filed: 1959-04-27
Abstract: 857,838. Printing surfaces. ETABLISSEMENTS V. SIMON. April 27, 1959 [April 26, 1958], No. 14258/59. Class 100(2) A printing roller for printing multicoloured striped patterns on fabrics and the like comprises a close succession of discs made of a solid soluble plastified colouring substance mounted on a supporting shaft of relatively small diameter. As shown, a roller for printing undulated stripes comprises printing discs 22 clamped between heads 23 having parallel oblique faces and mounted on a shaft 1. The heads 23 and discs 22 may be made of the same plastified substance, soluble in an appropriate solvent, so that they are all reduced uniformly in diameter in use, but additionally the discs contain a colouring substance. The solvent may be applied to the fabric or to the roller. Each disc 22 may be about one millimetre thick, and where thick stripes of the same colour are required, several discs of the same colour are arranged together. In a modification, the clamping faces of the heads 23 may be undulated so that the discs 22 are squeezed together in undulated fashion. Straight stripes can be printed by using clamping heads with plane clamping faces perpendicular to the axis of the shaft. The discs and clamping heads may be made from polyvinylic alcohols to which polyacrylic or acetic acids are added. For example, the discs may be prepared by dissolving 200 g. of polyvinylic alcohol, 20 g. of polyacrylic acid, 10 g. of glycerine, 20 g. of a blue dye, and 5 g. of silica in one litre of water maintained at 80‹C. The solution is then screened and cast on moulding plates to form sheets from 2 to 3 mm. thick, from which the discs may be cut.

Filed: 1927-05-27
Abstract: 280,452. J÷rgensen, M., and Hertz, J., (trading as J÷rgensen & Co., A.). May 27, 1927. Conical mills; hollow cylinder and internal guided roller.-In a coffee mill of the kind in which, in the event of a hard foreign body coming between the grinding-bodies, the normally stationary outer grinding-body is coupled by the hard body to the inner grinding-body and thus rotates therewith to prevent damage to the teeth of the grinding-bodies, part of the outer grinding- body at or near the point where the coffee beans are introduced into the space between the two grinding-bodies is movable relatively to the remaining part of the outer grinding-body and the mill casing is provided with an opening to receive the movable part and through which the hard body is thrown out. As shown, the annular grinding-body 5 is secured in a cylindrical carrier 6 mounted in the mill casing 7 so that it can be rotated therein although it is normally held stationary by two spring-pressed studs 8. and a shutter or flap 10 carrying a separate part 13 of the annulus 5 is pivoted at 11 to the carrier 6. By means of a screw 12, the shutter 10 can be adjusted towards or from the runner 4 to regulate the supply of coffee beans to the mill. When the members 4, 6 rotate together and the shutter 10 comes opposite an opening 14 in the lower part of the mill casing 7, the shutter falls down into this opening and the hard foreign body is thrown into a drawer 15 below the casing, the rotor 4 continuing its movement while the carrier 6 is stopped. By inserting a pin &c. through a slot 17 in the casing 7 into one or other of a circumferential series of recesses 16 in the carrier 6 the parts 5, 6, 10. 13 may be returned to their original position while the mill is still running. A circumferential groove 18 in the carrier 6 ensures that the adjusting-screw 12 does not prevent the carrier from rotating. A spring may be provided to open the shutter when it comes opposite the opening 14.

Title: Improvements in apparatus for playing table skittle games
IPC: A63D3/00
Filed: 1933-05-19
Abstract: 419,745. Coin - freed game apparatus. HIGGINS, R., 16, William Morris Close, Forest Road, Walthamstow, London. May 19, 1933, No. 14491. [Class 27.] In a skittle game apparatus the skittles are positioned at the top of an inclined table and the game is played by spring projecting a ball from the bottom of the table indirectly at the skittles. The skittles are reset from outside the casing, and the ball, when it has rolled tc the bottom of the table, is returned to the pivotal projector by actuating a directing mechanism. The directing mechanism is coin-freed and after a predetermined number of actuations is relocked until the insertion of another coin. The table 3 is contained in a glass topped casing 1 and provided with an obstacle 44 so that the ball 42 must be projected on to the side and obstacle cushions 45 to hit the skittles 4. The latter are secured by cords or the like 5 to a plate 7 and reset by retracting a spring- pressed rod 8 secured to the plate. The projector 37 is pivoted at 38 and has guides 41 to position the ball 42 in front of the spring-pressed plunger 39. The directing mechanism comprises arms 32 pivoted at 31, and rotated against biassing springs 34 to direct the ball, resting thereagainst, past the adjacent guide 41 into projecting position, when a knob 25 is retracted. The knob 25 is carried by a rod 24 pivoted to a stud 23 on a pivoted lever 21. The stud 23 engages a slotted crank 26 carried by a lateral shaft 27 which is therefore rotated when knob 25 is retracted, arms 29 thereon rocking levers 30 rigid with the spindles 31 carrying the ball directing arms 32. For scoring purpose, pegs may be inserted in numbered holes formed in the upper face of the casing. Coin-freed mechanism.-At each retraction of the knob 25 a pawl 20 on lever 21, advances a ratchet wheel 19 one tooth. The ratchet wheel is rigid with a snail cam 17 and normally locked against rotation by a detent 16, carried by a lever 14, engaging in the notch of the cam. A coin inserted in the shoot 12 rocks lever 14 against the bias of a spring 15 lifting detent 16 out of the cam notch to free the ratchet wheel. The snail cam is so shaped, that at the second actuation of the knob 25 it rocks lever 14 still further whereupon the coin passes from lever 14 and falls into the box. The knob is actuated a number of times equal to the number of ratchet teeth when the snail cam is again locked by detent 14.

Abstract: 989, 644. Photo-electric measurement; electric measuring instruments. INSTITUTE FOR CANCER RESEARCH. April 16, 1962 [Oct. 18, 1961], No. 14657/62. Heading G1A. [Also in Divisions G2 and H4] Ultra-violet light derived from a source 20 (e.g. a xenon arc) by way of a monochromator 22 is scanned over a specimen 50 by means of a mirror 25 which is carried by a support 26 which is pivoted at 27 in a frame 28, the support being oscillated about the pivots to introduce a first component of scanning by means of an electromagnet system 32, 33 which co-operates with an armature arm 30 extending from support 26, and the frame 28 being oscillated in bearings 40 to introduce a second component of scanning by an arm 41 which engages a rotating cam 43 (see Fig. 2). The armature carries a weight 31 adjustably threaded on the armature, and the lower end of support 26 carries a leaf spring 34 which is secured so as to slide longitudinally between members 35, 36. Inward motion of the armature is limited by a rubber bumper 37. The mirror, support, armature, weight and leaf spring form a vibrating system which is adjusted to be resonant at the frequency of the alternating current applied to the electro-magnet solenoid 33. The scanning motion imparted by the mirror is substantially sinusoidal. In order to employ only the linear portion of the motion and, further, to restrict the scanning to one direction only, a shutter 54 (see Fig. 3) is rotated in the light beam between monochromator 22 and the mirror. The pin-point exit of the monochromator is imaged on the specimen by means of optical system 45, 46. The light passing through the specimen is detected by a photomultiplier 51. The resulting electric signal may be employed to reproduce an image on a cathoderay tube scanned synchronously with the mirror, Fig. 5 (not shown), or may be applied to an integrator and counter circuit to provide a measurement of the specimen density over the scanned area, Fig. 6 (not shown). Reference is made, without giving details, to the use with the invention of visible and infra-red light.
