Title: Improvements in printing telegraph receiving apparatus having case grouping of characters
IPC: H04L17/24
Filed: 1931-11-27
Abstract: 388,875. Type-printing telegraphy. CREED & CO., Ltd. arid GRIFFITH, R. G., Telegraph House, Croydon. Nov. 27, 1931, No. 32916. [Class 40 (iii).] A telegraph receiving- apparatus, particularly for languages having a large number of characters, comprising permutation members controlled by signal combinations is provided with two case-shift mechanisms, the first controlling in response to a case-signal selection in one or other of two case-groups of which each component has two characters, and the second controlling in response to a further case-signal selection of one or other of the characters. The first case-shift mechanism may include a supplementary permutation-bar which is displaced by means of selector-bars controlled by the other permutation-bars. The selecting- mechanism may be employed also for selecting printer-functions such as line-feed and pagefeed. In the apparatus shown in the Figure, five permutation-bars 29 .. 33 engage rocking arms 22, 23 co-operating with cams 20, 21 on members 12 .. 16 which are splined on a shaft 5 and are connected to longitudinally movable rods 11 mounted in discs 9, 10 on the shaft. A signal-receiving relay 1 releases a half-revolution clutch 4, and controls an interponent 3 for displacing the rods, the interponent being operated by a hammer 8 co-operating with a cam 7. A received signal-combination causes each of the members 12 .. 16 to be set in one or other of two axial positions to operate one or other of the associate pair of arms 22, 23 and thereby move the associated permutation-bar into one or other of two longitudinal positions. The displaced members 12 .. 16 are returned by means of cams 27 on a bar 26. Selector-bars for actuating a type-wheel or type-levers and other members of the printing-mechanism co-operate with the permutation-bars 29 .. 33, and a sixth permutation-bar 44 which is displaced to the right or left by means of a bell crank 45 operated by selector bars 34, 35 co-operating with the permutation-bars 29 .. 33. The permutationbars co-operate also with a selector-bar 37 for shifting a platen 51, and a selector-bar 36 for releasing a shift-lock 52. The bars 34, 35 are selected by case-shift and re-shift signals and constitute with the bar 44 the first case-shift mechanism, and the bars 37, 36 are selected by further case-shift and re-shift signals and constitute with the platen the second case-shift mechanism. Specification 388,785 is referred to.

Patent GB-368800-A (GB)
Title: Improvements in and relating to the construction of macadam roads
IPC: E01C7/26
Filed: 1930-11-05
Abstract: A method of making rolled macadam roads consists in binding the road metal by a pulverulent material containing an hydraulic cement together with a bituminous substance such as asphalt, tar, or pitch. The powdered material preferably consists of a mixture of lime, tar, and cement, the tar content not exceeding 15 per cent of the mixture. According to one method, the road metal is first laid and the binding agent then applied and raked in.  The road surface is then rolled, watered and rolled again.  Another method consists in applying the road metal over a layer of the powdered binding medium, loosely rolling the road surface, wetting, and again rolling.  In a further method, the binding agent is mixed with sand and water and applied to the road foundation, the road metal being subsequently laid thereon and rolled.  The hydraulic binding medium may be gypsum, stucco, alabaster, plaster, or a mixture of gypsum with lime and cement, and is admixed with the bituminous substance in such quantities that the mixture may be prepared in a grinding mill, pug mill, colloid mill or similar apparatus.  The Specification as open to inspection under Sect. 91 (3) (a) describes also a method in which the bituminous substance is added to the hydraulic binding medium in the form of a solution, or, alternatively, is poured on to the road ballast after the latter has been rolled in with the hydraulic binding agent.  The impregnation of the binding agent is aided by the use of mineral salts or watery emulsions of tar or bitumen, Trinidad asphalt, or bituminous substances registered under the names of "Mexphalt" or "Spramex" dissolved in chlorinated or other hydrocarbons or tar.  Old roads may be treated by applying a pulverulent hydraulic binding agent over a layer of coarse ballast.  This is rolled and watered, the penetration of the water being facilitated by mixing it with alcohol, acetone, or the like.  Emulsions of bitumen, or tar containing 10-20 per cent bitumen, may be used as impregnating agents.  In order to retard the drying action, small quantities of glycerin, sulphite liquor, or the like, are added to the water. The rolled road metal may be hardened by impregnation with water soluble salts of the borates, phosphates, fluor-silicates, alums, or earth alkali metal chlorides.  The bitumination of gypsum may be carried out by impregnating cold gypsum with tar or bitumen dissolved in organic hydrocarbons by treating it in friction mills, disintegrators, colloid mills or similar apparatus.  Alternatively tar or bitumen is admixed with pulverulent gypsum in the condition in which it is discharged from the gypsum boiler, the mixture being treated in the friction mill or the like.  A further method consists in adding the tar or bitumen directly in the gypsum boiler.  It is stated that the bituminated gypsum is capable of absorbing 10 per cent, or more, of road tar while still remaining in a pulverulent condition. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in means for filling bottles and the like containers with gas charged liquids
IPC: B67C3/04
Filed: 1922-12-06
Abstract: 190,158. Soc. Anon. de Construction de MatÚriel d'Alimentation. Dec. 6, 1921, [Convention date]. Bottling.-Relates to machines for filling bottles &c. with gas charged liquids. The liquid is saturated to a greater extent than is required for bottling and is delivered to a container or recuperator from which the bottle is to be supplied, causing the gas in the container above the liquid to be under pressure which serves to supply a dose of syrup or gas to the bottle. In the form shown, the recuperator comprises a container 13 enclosing a second open bottomed container 14 and with nozzles 15, 16 above and below the level of the liquid respectively. Gascharged liquid is introduced into the recuperator through a nozzle 17 and causes floats 23, 24 to rise and cut off the outflow of gas through nozzles 22, 19 respectively and creating pressure. A cock, Fig. 2, diagrammatic sections at AB, CD, and EF of which are shown in three positions each in Fig. 8, is connected to the recuperator at 15 above the level of the liquid, and the bottle 9 is connected at 16 below this level. The cock is turned to the position I, Fig. 8, and the nozzle 19 is opened. Liquid flows through a pipe 36 to the bottle and displaces the air content through connections 12a, 12, 4, 4<a>, 15 to the recuperator. A dose of syrup flows from the syrup tank 6<b> through connections 6<a>, 6, 8, 8a to the dosing device 8<b>, from which air escapes to the atmosphere through connections 7<a>, 7, 10. The exit of the liquid from the recuperator causes the floats 23, 24 to fall, gas escaping at 17 and air at 19. A new liquid charge is admitted at 17 before the air from the bottle can escape from the nozzle 19 and the cock is turned to position II, Fig. 8. The compressed air passes through connections 15, 5a, 5, 7, 7<a> to the closing device 8h and expels syrup to the bottle through connections 8<a>, 8, 11, 11<a>. The cock is then rotated to position III and the closing device is replenished through connections 6a, 6, 8, 8a, the air under pressure escaping to the atmosphere through connections 7<a>, 7, 10. Excess liquid escapes from the bottle through connections 12a, 12, 30, 3, 3<a>, and the cycle of operations is complete. The apparatus may be modified for gas closing instead of syrup closing by connected the nozzle 5 to the bottle instead of to the recuperator and opening the nozzle 7 to the air. The inner cylinder 14 may be dispensed with.

Abstract: 883,702. Stretching thermoplastic sheets. SWEDLOW Inc. Oct. 5, 1959, No. 33715/59. Class 87(2). [Also in Group XIII] To improve the physical (including optical) properties of a sheet of thermoplastic resin, e.g. polymethyl methacrylate, it is gripped at its edges and cooled at the points where it is gripped, whilst the rest of the sheet is heated and stretched. A sheet 24 is perforated at its edges and gripped by spring clips 51 which surround tubes 47 passing through the perforations. Each clip has flanges 50, 52 extending on each side of the sheet. The sheet suspended from a frame 30 is run into an oven where it is heated by hot air, whilst the parts where it is gripped are cooled by circulating cooling fluid through the pipes 47. Alternatively, it may be heated by infra-red heaters or in a fluid bath of oil or glycerine. After heating, the sheet is removed from the frame 30, and is secured by pins 102, Fig. 9, to cables 90 which are pulled by hydraulically operated pistons to stretch the sheet. The sheet may be heated during stretching by a hot air oven. In a modification, the sheet may be gripped by eccentric clamps with serrated edges. The sheet may be moulded by hot dies, blowing or suction whilst still hot. To compensate for the shrinkage due to cooling, the stretching force may be reduced slightly. The Specification includes several examples, giving the temperatures, and duration of and percentage stretch.
