Title: Process for the production of decorative materials and protective linings in sheet or web form from fibrous cellulose materials
IPC: B44F9/04
Filed: 1932-02-29
Abstract: 392,693. Decorative effects on paper &c. ; waterproofing. SOC. ANON. CARTIERE GIACOMO BOSSO and SILVESTRINI, N., 23, Via Cavour, Turin, Italy. Feb. 29, 1932, No. 6097. Convention date, Nov. 16, 1931. [Classes 96 and 140.] The irregular distribution of fibres is accentuated during the formation of sheets or webs of cellulose material to obtain decorative effects, e.g. marbling, veins, &c., whereupon the web &c. is passed through a gumming bath comprising a solution of gelatine and a substance containing the Si O2 group and then through a fixing bath, e.g. of liquid or gaseous formaldehyde, chromic acid or potassium bichromate and castor oil, thus waterproofing and strengthening the web &c. The irregularities may be accentuated by using high frequency and/or large amplitude shaking of the wire-cloth preferably using a linseed or other composition to increase the viscosity of the pulp. They may be further accentuated by the presses expelling water from the thicker parts which escapes via the thinner, and by twisting and winding, and crumpling or creasing the web which may have been treated with an astringent and rapidly dried. The gumming bath may be preceded by treatment with gases or vapours, e.g. acetic acid which may be applied to sheets &c. in a vacuum chamber and may comprise silicic acid, e.g. in the colloidal state, or silicates of sodium, potassium, &c., e.g. equivalent to a 1 per cent. solution for a foldable product or more for stiff products ; fine dry gelatine, e.g. 25 kilograms being dissolved in 100 litres of water and the temperature raised to 50-70‹ C. The bath may also contain salts of alkaline earth metals, e.g. calcium, or of tin, aluminium, copper, &c., which with fat substances, may produce insoluble soaps having a waterproofing action. The web is then dried in an air current at 5-20‹ C., and passed through a fixing bath.

Abstract: 494,941. Extrusion presses. WOLVERINE TUBE CO. March 2, 1937, No. 6216. Convention date, March 23, 1936. [Class 83 (iv)] An extrusion press has a movable tool for forcing the stock, through a die means for removing excess metal from the end, means for moving a shearing punch supported for swinging into the path of the movable tool when retracted, and a spacer for actuating the punch. As shown, a heated billet A is compressed in a lined container 27, Figs. 1 and 2, and is then pierced and extruded by a tool 22, 24, 26. The residue in the form of a flange C, Fig. 5, is severed by a tool E carried on an arm 34, which is pivoted on a shaft 35 at the free end of a bracket 36. The bracket 36 is pivoted on a shaft 37 moved axially by a piston 38. The arm 36 and tool E swings inwardly and slides to contact the flange C. A spacer F carried by an arm 41 on the shaft 35 is then swung in, and is engaged by the extrusion plunger 24 to sever the residue. Slots in the holder 33 and spacer F, respectively, accommodate the piercing pin 26. After swinging the spacer sideways, the punch E is raised and carries with it the residue C. A cooling device G forming the subject-matter of Specification 494,942, for the extrusion punch and piercing tool is connected to a boss of the arm 34 by another arm socket when the arm 36, is moved against a stop F the cooling device is brought beneath the punch.

Abstract: 471,361. Automatic control systems; rectifying alternating currents. BRITISH THOMSON-HOUSTON CO., Ltd. March 2, 1936, No. 6301.. Convention date, March 1, 1935. [Classes 38 (ii) and 38 (iv)] [Also in Group XXXVII] Speed.-When a control arm 43 is moved from its central position, one of two reversing switches 45, 46, is closed to connect the field winding 14 of the generator of a Ward-Leonard system to a source 20, through a grid-controlled discharge device 21, a control arm 38 remaining in contact with a segment 56, and the grid of the device 21 being subjected to a bias voltage lagging the anode voltage by 90‹ and obtained from a transformer 25. No appreciable current flows through the device 21 and the motor 10 is not started. The control arm 38 is then moved over potentiometer resistance 35 to an extent corresponding to the desired speed of the motor, and a condenser 29 in the grid circuit of the device 21 is subjected to a corresponding voltage through a resistance 41 and a rectifier 42. The device 21 is thus rendered conducting and the generator field and motor speed build up. The grid circuit includes a voltage which is derived from a generator 19 driven by the motor 10 and opposes the condenser voltage. The motor accelerates in accordance with the rate at which the condenser charges until the voltage of the generator 19 matches the condenser voltage. The system then operates to maintain the speed uniform. When the control arm 38 is moved towards its central position the condenser 29 discharges through a resistance 40, and the motor decelerates, the voltage of the generator 19 again being matched to the condenser voltage. The connection of the generator 19 in the grid circuit is reversed with the reversal of the generator field 14 by means of contacts 32, 33, operated with the reversing contactors 45, 46. A second device similar to the device 21 may be provided to rectify the other half of the alternating voltage wave, or, as shown, the field 14 may be maintained during the negative half-wave bv a rectifier 47 connected in parallel with the field, and rendered conducting by the induced voltage in the field winding.

Abstract: 1416908 Fuel injection pumps; treating I C engines charging H B GROW 10 Feb 1973 6660/73 Headings F1A and F1B A fuel injection pump for delivering a fueldilutant mixture through an outlet 58 to a compression ignition engine, comprises a variable volume storage chamber X, a fixed or variable volume transfer chamber Y in permanent communication with the storage chamber X and supply means E, F for charging the transfer chamber Y with metered quantities of fuel (e.g. fossil fuel or alcohol) and fuel dilutant (water or mineral oil) in timed relation to the engine. In the embodiment shown in Fig. 5 the transfer chamber Y is variable in volume by a partition piston B having a piston rod 23, 24, the larger rod part 23 extending through the chamber X and the smaller rod part 24 extending through the chamber Y. Thus during a suction stroke of the piston B, fuel-dilutant mixture left in the storage chamber X from the previous cycle flows into the transfer chamber Y to be mixed with the next charges of fuel and dilutant supplied to the chamber Y. This helps to average out changes in the mixture strength caused by operation of the supply means E and F. The supply means E comprises a pump 34, a regulating valve 36 and an electrically operated valve 30. Similarly the supply means F comprises a pump 33, a regulating valve 37 and an electrically operated valve 31. The supply means E' and F operate to deliver a constant total volume of fuel and dilutant, but in variable proportions. The variable proportioning is achieved by opening and closing the valves 36, 37 simultaneously and by arranging the regulators 36, 37 to vary the pressure output to the valves 30 31, inversely. Alternatively the pressures of the fuel and dilutant are kept constant and the amounts the valves 30, 31 are opened or the time periods the valves are opened are varied inversely. In the former alternative a rheostat having a movable contact 47 connected to a contactor 50 is used to control the energization of coils 45, 46 for opening the valves 30, 31 contactor 50 revolves with a shaft 27 having a cam 26 for reciprocating the piston B, the contactor 50 conducting current only during the intake stroke of the piston B. In the embodiment shown in Fig. 8 the transfer chamber Y is of constant volume, the storage chamber X being varied in volume by a ram C which never reduces the chamber X to zero. The chambers X, Y are in permanent communication through a passage 22 in a partition 22. The outlet 58 from the chamber Y may be provided in the rod part 24 and lead to an injector nozzle G<SP>1</SP>, Fig. 6 (not shown) The communication between the chambers may be provided by a clearance space between the partition piston B and its cylinder 19, Fig. 9 (not shown) or by an external pipe, Fig. 11 (not shown). The chamber Y of the Fig 8 embodiment may be rendered variable by a second ram (24 ") driven in unison with the ram C, Fig. 7 (not shown).
