Title: Improvements in method of delivering printed sheets on rotary printing machines
IPC: B65H29/10
Filed: 1919-06-04
Abstract: 148,673. Bernard, S. June 4, 1919. Delivering apparatus; grippers and gripper mechanism. - Sheets are delivered from a printing- machine by a drop-sheet delivery device comprising a reciprocating carrier C to which the sheets are delivered from the impression cylinder I. The carrier is moved towards a set of fixed grippers A which are opened by the action of the carrier C on an arm E on the gripper shaft, and close on the sheet by spring action as the carrier returns. The grippers are finally opened, after the rear edge of the sheet has dropped on to a table D, by means of an incline G on the carrier acting on a lever H connected by a rod F to the lever arm E. The carrier is reciprocated by adjustable crank mechanism from the impression cylinder I, so as to be capable of dealing with sheets of different sizes. The carrier is formed with tapes or slats which are withdrawn from under the sheet as the carrier returns.

Title: Improvements in or relating to the production of chloroaryloxyalkylcarboxylic compounds
IPC: C07C59/70
Filed: 1943-08-30
Abstract: Salts of chloroaryloxyalkylcarboxylic acids are made by reacting a nuclear chlorinated phenol with an excess of an a -haloalkylcarboxylic acid in presence of an alkali in amount corresponding to an excess over both the phenol and the acid, a part of the acid and a part of the alkali corresponding to an excess over said part of the acid, being added gradually or in one or more portions to the reacting or reacted mixture of the phenol with the remainder of the acid and alkali.  The salts may be isolated as such and then converted to the corresponding acids or the acid may be isolated from the reaction mixture by acidification and separation, e.g. by extraction with a solvent such as ether, toluene or carbon tetrachloride.  The corresponding carboxylic acid esters, amides, halides and salts may be made from the acids or their salts by standard processes, the production of methyl, ethyl, propyl, isopropyl, butyl and isobutyl esters being referred to.  The chlorinated phenol may be of the benzene or naphthalene series, may contain one or more phenolic hydroxy groups and may be substituted by alkyl groups, methyl, ethyl, propyl and isopropyl being specified. The alkali employed in the reaction is an alkali metal hydroxide or carbonate or an alkaline earth metal hydroxide, sodium hydroxide or carbonate being specified.  Salts of the acids may be made by neutralizing the acid with a base such as an oxide, hydroxide or carbonate of iron, copper, nickel, zinc or lead or by double decomposition between a soluble salt of the acid and a solution of a salt of the corresponding base.  In the examples, 2-methyl-4-chlorophenoxyacetic acid is made from 2-methyl-4-chlorophenol, monochloracetic acid and caustic soda. It may be purified by making its methyl ester, washing with aqueous alkali and hydrolysing.  Other chlorinated phenols specified are the chloro-o-cresols, 2.4-dichloro- or 2.4.6-trichloro-phenol and 1-chloro-2-naphthol.  Other acids specified are a -chloro-or a -bromo-propionic acid and similar derivatives of butyric and isobutyric acids.  Samples have been furnished under Sect. 2 (5) of the following compounds: (A) 4-chloro-2-methyl-phenoxyacetyl chloride; (B) 4-chloro-2-methyl-phenoxyacetamide; (C) sodium 1 - chloro - 2 - naphthoxyacetate; (D) 1-chloro-2-naphthoxy-acetic acid; (E) ethyl 1-chloro-2-naphthoxy-acetate.

Title: Improvements in or relating to felt hat brim finishing machines
IPC: A42C1/06
Filed: 1926-06-07
Abstract: 276,755. Turner, A., and Turner, W. E. June 7, 1926. Pouncing.-Relates to felt-hat-brim finishing machines of the kind in which two horizontal levers carry sandpaper-covered pads which are rapidly oscillated in contact with the upper and lower surfaces of the brim, and consists in improved mechanism by which the machine can be set to perform a predetermined number of oscillations and then, automatically, stop with the upper pad lifted for the removal and introduction of work. The work table k is adjustably pivoted to an arm j', itself pivoted to the machine frame and held in adjusted position by a clamp passing through a radial slot in a bracket j. Upper and lower pads are mounted on levers e, e<2> oscillated about a shaft f by oppositely-disposed eccentrics on a shaft d. The upper lever e<1> is vertically slidable, and is supported by a rod e<3> from a lever n pivoted at n<2> and weighted at its free end. A slotted link q supports this lever from a lever p<6> keyed to a rock-shaft p<5> and urged upwardly at its free end by a spring p<9>. The other end of the lever p<6> is linked to a treadle p<7>. The main shaft h, carrying fast and loose pulleys i, i<*> and a pulley g driving the shaft d, also carries a chain wheel h<1> driving a shaft o on which is a worm o'. The worm wheel is mounted in a bearing o<8> pivoted in a bracket o<9> and tilted in or out of mesh with the worm by a lever p<2> linked to an arm on the rock shaft p<5>. On the shaft of the worm-wheel is a plate p formed with a concentric slot along which a block p' with an inclined end may be adjusted. A spring catch normally holds the lever p<6> in its lower position. After a number of oscillations of the pads determined by the position of the block p' in its slot, the block releases the catch and allows the spring p‹ to raise the lever p<6> and rock the shaft p<5>. The raising of the lever p<6> raises the upper pad, and the rocking of the shaft p' takes the worm-wheel out of mesh with the worm o'. The worm-wheel is weighted so that, on release from the worm, it returns to starting position. At the same time a further arm on the shaft p<5> moves belt-shifting forks to shift the belt on to the loose pulley. The table. k carries a roller l engaging the inside of the hat and retracted along a guide to permit change of work by a handle l<3>. A spring l<1> normally holds the roller in operative position. A work-shield m is also operatively connected to the handle l<3>, so that it is tipped out of the way simultaneously with the retraction of the roller l. The weighted lever n also separates the usual feeding-cones, simultaneously with the raising of the upper pad lever e', by rods o', o<6> and an intermediate lever.

Title: Improvements in ionic amplifier or detector tube
IPC: H01J17/56
Filed: 1934-05-11
Abstract: 439,879. Thermionic valves. RUBEN, S., 265, Storer Avenue, New Rochelle, New York, U.S.A. May 11, 1934, No. 14306. Convention date, Dec. 16, 1933. [Class 39 (i)] In an ionic amplifier or detector in which the distance between the control grid and cathode is determined by a property of a vapour which is affected by pressure or temperature, the filling consists of a mixture of vapours of which one has a low and the other a high vapour pressure, for example mercury and cadmium ; the distance between the control grid and cathode is less than the mean free path of the electrons. An amalgam consisting of 20 to 30 per cent of mercury and 80 to 70 per cent of cadmium may be used ; neon, helium and argon may be added. As shown, an indirectly-heated cathode 2 is surrounded by a control grid 3, two positivelybiassed grids 4, 5 and an anode 6, and the discharge is confined to the space between the electrodes by mica discs 8, 9 or by a transverse electric field. The grids have the same number of turns ; the spacing between the control grid 2 and the grid 3, and between the grids 3, 4 is the same as that between the cathode and the control grid. Dimensions and applied voltages are given. The voltage applied to the grid 4 should be such as to prevent a localized ionic discharge from it to the cathode through the control grid ; the grid 5 acts in a similar way. In order to reduce sputtering, one or more of the grids is coated with a material, such as beryllium, aluminium or carbon having a lower atomic number than the material of the grid, for example a grid may be coated with a mixture of 80 per cent colloidal graphite and 20 per cent aluminium powder in a carrier of alcohol and ammonia and the grid heated to 800 C. before assembly. Specification 438,961 is referred to. The Specification as open to inspection under Sect. 91 comprises also fillings of sodium and potassium amalgams. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,006,567. Paper-making machines. FELDMUHLE A.G. April 16, 1962 [April 26, 1961], No. 14677/62. Heading D2A. Multi-layer webs of fibrous material, such as paper, are formed by passing pulp suspensions along separate channels superposed directly one above the other on to an inclined portion of a wirecloth. Suction chambers arranged behind the wirecloth relative to each channel have provision for independently controllable reduced pressure in each chamber. In one embodiment, the pulp is supplied along three independent channels 1, 2, 3 to wire 7 inclined at an angle greater than 20 degrees to the direction of flow in the channels and behind which are the suction chambers 8-12. Pulp water is independently circulated from these. A housing 20 filled with water up to the same level as that in the channel 3 surrounds the suction chambers and prevents loss of fibres through the gap 21. In a modification, Fig. 3 (not shown), top and bottom channels are supplied from one inlet and the middle channel is separately supplied. In addition instead of the housing 20, a sealing device is provided to prevent leakage from the channel 22 at the gap beside the wire.

Abstract: 1320307 Control system for gas-fired water heater JOH VAILLANT KG 13 May 1971 [25 May 1970] 14680/71 Heading F4T [Also in Division F2] A gas control system for a water heater comprises an ignition safety valve 3 in a fuel inlet 2, a control valve 16 mounted coaxially with a valve tappet 17 and pivoting handle 13, an ignition gas valve 11 mounted in an ignition gas duct 9 and an electromagnet 33 activated by a thermocouple in the ignition flame, so that when three cams 37 on the handle 13 are rotated from off-position ratchets 38 into ignition-position ratchets 62 of three cam tracks on a thrust member 40 a further cam 35 on the handle opens the ignition gas valve 11, and when a button 53 mounted in handle 13 is depressed the safety valve 3 is also opened to allow gas to reach the ignition burner while at the same time a pivoted lever 25 forces an armature plate 28 against magnet 33 where it is subsequently retained by the presence of an ignition flame thereby maintaining open valve 3 when button 53 is release#s and further rotation of handle 13 brings cams 37 into ratchets 63 under the force of a spring 41 which also thereby opens valve 16 allowing gas to reach the main burner via an outlet 64. If the ignition burner is extinguished, the magnet 33 releases the plate 28 thereby closing valve 3 under the bias of a spring 4, and this sequence may be intentionally initiated by turning back handle 13 closing in turn the control and ignition valves. The handle is axially restrained by a ring 34 and the button 53 may be depressed only in the ignition position of the handle when ribs 56 are aligned with grooves 57. A stop abutment 55 on the valve tappet 17 prevents release of the button 53 from its depressed position if the tappet becomes jammed, thereby preventing opening of the control valve and consequent passage of gas to the main burner. Fig. 5 shows an alternative arrangement of the constructional parts wherein the safety and control valves 78 and 80 and the valve tappet 89 are no longer coaxial with the pivoting handle 106 which is mounted on a thrust pin 102, and a rocker lever 100 with a clevis end 98 is employed to communicate between the two systems. Instead of having a button as 53, the handle itself can now be depressed to open the safety valve. A valve 74 is operable by an external screw 73 to adjust the gas inlet rate of flow.
