IPC: C08G8/24
Filed: 1949-02-26
Abstract: A powdered adhesive, wholly or partially soluble in water, contains a mixture, hardenable by heating in the absence of hardening agents, of unsulphonated condensation products of phenols and formaldehyde and condensation products of phenols and formaldehyde which contain neutralized sulphonic acid groups. Specified phenols are phenol, the cresols and the xylenols.  The adhesive may be mixed with melamine- or carbamide-formaldehyde resins.  In examples, (1) An acid catalysed phenol-formaldehyde condensate is sulphonated, neutralized, converted into a dry powder and mixed with a powdered alkali catalysed phenol-formaldehyde condensate.  (2) A phenol is partially sulphonated and condensed, if desired after its neutralization, with formaldehyde in alkaline medium.  It is then converted into a powder. (3) A phenol sulphonic acid is neutralized, condensed with formaldehyde in alkaline solution and mixed with a solution of an alkali catalysed phenol-formaldehyde condensate.  Alkali is added to the resultant solution which is then dried.  (4) A mixture of phenol and phenol sulphonic acid is neutralized and condensed with formaldehyde in alkaline solution which is then dried. Specifications 703,234 and 703,235 are referred to.

Title: Improvements in or relating to Audion or Lamp Relay or Amplifying Apparatus for use in Telephony.
Inventor: LATOUR MARIUS
IPC: H03C1/16
Filed: 1917-04-16
Abstract: 131,056. Latour, M. April 15, 1916, [Convention date]. Correcting distortion in long lines by emphasizing speech currents of higher frequency. - Distortion of speech in long-distance telephony is corrected by the employment, at the transmitting or receiving station, of vacuum-tube amplifiers the circuits of which are arranged to emphasise the speech current components of higher frequency. Fig. 1 shows the apparatus arranged at the transmitting-station. A battery 7 and microphone 6 are in circuit with the primary of a transformer T<1>, the secondary of which is connected across the grid 3 and filament 4 of a vacuum-tube amplifier. The plate circuit of this tube feeds the grid circuit of a second tube through a transformer T<2>, and the plate circuit of the second tube feeds the line L through a transformer T<3>. Each transformer primary is shunted by an inductance 8 which gives preference of passage to the low-frequency speech components, the apparatus as a whole thus emphasizing the highfrequency components. Alternatively, the transformers may be constructed to take a large magnetizing-current, for example by providing an airgap in the magnetic circuits. When the amplifier is used at the receiving-station, the line-wires feed the primary of the transformer T<1>, and a telephone receiver is placed across the secondary of the transformer T<3>. In this case, small series condensers replace the shunt inductances 8; or the. primary circuits of the transformers may include a condenser and inductance, placed in parallel and proportioned to offer a greater impedance for low than for higher frequencies. The same set of vacuum tubes may be used for transmission and reception, a switch being arranged for making the necessary changes in the circuit connexions. This switch may also be arranged to change the transformation ratio of the transformers.

Title: An improved method of printing
IPC: B41C1/06
Filed: 1931-02-27
Abstract: 375,774. Printing processes ; etching. BERIAU, O. A., 14, Elgin Street, Quebec, Canada. Feb. 27, 1931, No. 6117. Convention date, March 1, 1930. Drawings to Specification. [Class 100. (ii).] A process for obtaining printing-plates for reproducing the natural appearance and colours of marble and other materials consists in selectively etching the surface of the material by chemical agents to form relief designs, and transferring the designs in acid-resisting ink to form metal printing-plates by, etching ; a grain or screen plate is formed from the first etching of the material and colour-printing plates from successive etchings thereof. A slab of.marble, having'for example white, green, and red components, is etched in hydrochloric acid to develop the grain, and the etched surface is used to produce a metal printing-plate The'surface is then selectively etched for the white components, duplicate metal plates are deep etched in this design, and the depressions in these plates, corresponding to the white components, are filled in with acid resist. A further selective etching of the slab, attacking the green components, leaves the red design in relief. This design is transferred in acid resisting ink to one of the duplicate metal plates, which is then deep etched to form the red colour plate. This plate is also used to apply to the complementary plate a red design in soluble ink, after which the complementary plate is coated all over with acid-resisting ink, treated with water or other solvent to remove the parts of the coating over the soluble ink, and then deep etched to form the green colour plate. The grain or screen plate obtained from the first etching is used to apply a relatively light impression in black or other shade, either as the first impression on a selected ground colour, or as the final impression after the colour impressions, and is also used to form a grained surface on the two colour plates. The plates may be used directly for printing, or transfers, stereotypes, electrotypes, intaglio plates, or lithographic plates may be made therefrom.

Filed: 1955-03-02
Abstract: 765,758. Lubricating. WHITELEGG & ROGERS, Ltd. March 2, 1955, No. 6229/55. Class 12 (3). Means for providing intermittently a supply of lubricant under pressure comprise a reservoir for lubricant, a screw impeller supplied from the reservoir, means to drive the screw impeller intermittently, and a distributer served by the impeller with lubricant under pressure. In the construction shown the invention is applied to the lubrication of rails of railway tracks. A casing 10 is clamped to a rail 11 by means of an L-shaped rod 14 and a clamping member 15. The casing has connected thereto a barrel 18 which is connected by a flexible pipe 20 to a reservoir containing lubricant, and the casing is also connected by a flexible pipe 22 to means for distributing lubricant to the outside of the rail 11. The barrel 18 contains a screw impeller 23 which at one end has a square bore to receive a squared spigot 24. The spigot is integral with a rotatably mounted journal 25 to which is connected a ratchet wheel 27. The casing 10 carries an apertured bracket 29 forming an abutment for one end of a spring 30 surrounding a plunger 32 which extends through the bracket and is pivotally connected at its lower end to a pivoted lever 35 carrying a spring-pressed pawl 37. The plunger 32 at its upper end has a skirt 31 to receive the upper end of the spring 30 and a nose 33 which is normally just above the level of the top of the rail 11. When a wheel of a vehicle passes over the device it depresses the plunger whereby the pawl engages the ratchet to turn the screw impeller. The passage of several wheels causes lubricant to be forced through the flexible pipe 22 to the distributer, which comprises a hollow bar 43 formed with passages 45 through which lubricant is delivered to the side of the rail. To compensate for wear which may take place in the rail or in the vehicle wheels, the normal position of the plunger 32 can be adjusted by means of a stud 41 and locknut 42. The invention may also be applied to other apparatus, e.g. printing machines, conveyer belts, escalators or lifts.
