Title: Apparatus for supplying web material
IPC: B29D30/30
Filed: 1942-07-01
Abstract: 557,019. Feeding webs. WINGFOOT CORPORATION. July 1, 1942, No. 9097. Convention date, March 28, 1942. [Class 100 (i)] [Also in Group XL] Web supplying apparatus, particularly for supplying rubberized fabric to a tyre-building apparatus, comprises means for unwinding a web of material from a roll by winding up an associated liner web and means for automatically stopping the winding means up when a predetermined amount of the material is unwound. As shown in Figs. 3 and 7, a turret 18 rotatable about a fixed post 10 comprises vertical plates 20 each carrying a spindle 34 to support a roll of tyre making material with its liner and a winding spindle 40 for the liner material, the materials passing from the roll over a curved stretching bar 54, and a guide roller 58, the tyre material W passing to the front of and the liner L to the rear of the roller 60 and the tyre material hanging down over a guide apron 78. Each winding spindle 40 is driven by its own motor 42 mounted on the turret, and the motor circuit is controlled automatically so that the winding of the web L and thus the feed of the web W are anchored when a predetermined length of web W is fed and is restarted when the length of web is removed. One form of such control is effected by a light source 72, Fig. 7, and a photo-electric cell 84 on opposite sides of an orifice 76 in the apron 78. When the orifice is covered by the web W, the motor 42 is stopped and the operation tears the length of web off, an adjustable measuring device 110 being provided to facilitate this operation. The motor 42 is then automatically restarted until the orifice 76 is again covered. In an alternative form of control, the lower end of the web W engages a plate 90, Fig. 3, forming one end of a lever so as to tilt the lever and operate a switch The motor may also be 'arrested permanently when the web W is exhausted by the opening of a switch in the motor circuit by a relay energized when a contact 164, Fig. 7, carried by a conductor 162 makes contact with the roller 60 due to the absence of the web W. The turret is rotated to bring pairs of adjacent supply devices in turn to the operator by an electric motor 136 carried by the turret and driving a chain 142 passing round a fixed chain wheel 144 on the base of the post 10. This motor is started simultaneously with the motor 42 which is set into operation when a length of web from the second of the pair of supply devices is removed. The motor 136 is stopped by the opening of a limit switch actuated by a fixed cam in the post 10.

Title: Cellular resinous compositions
IPC: C08J9/06
Filed: 1945-04-12
Abstract: Cellular materials are produced by incorporating a substance which liberates gas at elevated temperature in a composition comprising a copolymer of vinyl chloride with up to 100 per cent of its weight of a dialkyl fumarate and a plasticiser for the copolymer, and then heating to liberate the gas.  Listed fumarates are the dimethyl, diethyl, di-n-butyl, diisobutyl, dicyclohexyl, dibenzyl and di-(chloroethyl) esters.  Suitable plasticisers include dimethyl, diethyl, dibutyl and dioctyl phthalates, tricresyl and tricetyl phosphates, methoxyethyl acetyl ricinoleate, di-(butoxyethyl) sebacate, triethylene glycol di-(2-ethyl hexanoate) and linear polyesters, e.g. 1.2-propylene sebacate.  Specified blowing agents include carbonates, bicarbonates, sulphites, bisulphites, metabisulphites, nitrites and stabilized diazo compounds, e.g. diazoaminobenzene.  Where an inorganic blowing agent is used, preferably a small amount of an acid such as stearic acid is incorporated in the composition. Cured cellular materials may be obtained by addition of curing agents, e.g. magnesium or zinc oxide or a butyraldehyde-aniline condensation product or sulphur and a rubber accelerator and a Group II metal oxide.  Other ingredients, e.g. pigments and stabilizers, may also be added.  Specified uses for the cellular products include mats, arm rests, cushions, toys, insulating materials and sponges.  In the examples, the preparation of the copolymer in aqueous emulsion is described, using an aqueous medium containing ammonium persulphate and the sodium salt of a sulphonated paraffin oil and the pH adjusted to 3 by addition of formic acid.  The sodium salt of sulphonated paraffin oil is obtained by passing a mixture of sulphur dioxide and chlorine into a refined petroleum oil of initial b.p. 266 DEG  C., heated to 90-102 DEG  C. The reaction was catalysed by light.  The product was hydrolysed by pouring into sodium hydroxide solution and unreacted oil removed by separation and ether extraction of the aqueous solution. Specifications 570,331 and 586,796 are referred to.

Title: Improvements in or relating to methods of purifying beryllium
Inventor: POTARD CLAUDE
IPC: C22B35/00
Filed: 1966-03-03
Abstract: In a process for purifying impure beryllium or alloys of aluminium and beryllium the starting materials is dissolved in a metallic solvent (e.g. Al or an alloy thereof with one or more of Si Mg and Zn), the solution is subjected to fractional crystallization and filtered, the beryllium residue then being subjected to a second purification step to remove excess solvent and the impurities. The second step may be carried out using a dilute mineral base, extraction at low temperature with a metal such as Mg or Zn or at high temperature e.g. above the melting point of beryllium with a metal such as Sb.  The beryllium may be thrown out of solution in the first step by lowering the temperature or by the addition of a third element to lower the solubility of Be in Al and the filtration may be carried out centrifugally.

Title: Improvements in side register mechanism for printing presses
IPC: B65H9/10
Filed: 1922-04-04
Abstract: 199,518. Marks, E. C. R., (Miehle Printing Press & Manufacturing Co.). April 4, 1922. Sheet - registering devices; sheet-smoothers. - Sheets are registered as they are fed to printing-presses by a lateral guide which is moved transversely to the direction of feed and can be moved in either direction according to which side of the sheet the guide engages, and means are provided in the form of a bar or the like which extends completely across the sheet and overlies the same to prevent buckling thereof as it is being sideregistered. The invention is described in connection with a vertical cylinder machine of the kind described in Specification 184,582 in which a bed reciprocates vertically in a direction opposite to a cylinder frame 12, 13, which carries a feed table 41 on which a sheet is registered as the cylinder frame descends. The edge of the sheet is engaged by a side guide 28, Figs. 1 and 2, which can be set along a rod 27<1> in either of the positions shown according to whether it is to be moved to the right or left to register the sheet. The guide 28 is held in the desired position on rod 27<1> by a screw 29. The rod 27<1> is carried by arms 27 on a rod 11 which is connected to a sleeve 14, Fig. 3, by means of a micrometer screw 24 which permits a fine adjustment of the guide 28 to be obtained. The sleeve 14 is mounted to slide in a bushing 15 in the frame member 12, and it is fitted with a collar 22 provided with a roller 23 which engages a cam member 39 as the cylinder frame descends, and is thus moved to the right or left according to the position in which the cam is set. The shaft 11 is rotated prior to the action of cam 39 by a fixed cam 46 which rotates a sleeve 48, to which the shaft 11 is keyed, against the action of a coiled spring 51. The shaft 11 in its transverse movements compresses a coiled spring 35, or 37, which restores the shaft to its normal position after the cam 39 ceases to act. The guide 28 is provided with a lower projection 42 which is received in a groove 43 in the table 41 to guide the lateral movement. While the guide 28 is moving the sheet, the rod 27<1> prevents lateral and longitudinal buckling of the sheet.

Title: Improvements in or relating to telemetering systems
IPC: G01F23/26
Filed: 1945-04-19
Abstract: 594,799. Telemetering systems. LIQUIDOMETER CORPORATION. April 19, 1945, No. 9845. Convention date, Oct. 6, 1944. [Class 40 (i)] [Also in Group XXXVI] In a telemetering system, particularly concerned with the measurement of liquid levels in tanks, the changes in output of an oscillatory circuit produced by changes in the capacity of a condenser partially immersed in a liquid (occasioned by changes of liquid level) affect the balance of a bridge, the degree of unbalance of which is shown by an indicator which may be calibrated to read the liquid level directly. As shown in Fig. 1, the condenser 11 is in series with condenser 22 across an oscillatory circuit consisting of condenser 18 and coil 17, and is partially immersed in the liquid in a tank. The excitation voltage applied to the control grid 14c of the valve 14 varies with the capacity of condenser 11, controlled by the liquid level. The output of valve 14 is applied to the control grid 15c of the valve 15. The bridge is comprised of the valves 15 and 16, and resistors 24 and 25. An indicator 13 is connected by leads 37 and 36 to the junctions 42 and 43. The potential of the control grid 16c is fixed during operation. Thus, changes in level result in changes in the degree of unbalance of the bridge which are measurable. on the scale of the indicator 13. Modifications are described in which the output of the valve 14 is applied : (a) to this similar bridge circuits simultaneously, the degree of unbalance of each affecting the currents flowing in each of the two coils of a ratiometer, Figs. 6-8 (not shown) ; (b) to a similar bridge, the degree of unbalance of which is measured by a further bridge, two arms of which are the two coils of a ratiometer and the other two arms the plate resistances of two further valves, Figs. 9-11 (not shown) ; (c) to a bridge two arms of which are the plate resistances of two valves and the other two arms the two coils of a ratiometer. The degree of unbalance is measured by the ratiometer, Figs. 3-5 (not shown).

Title: Electronic injection timing control for fuel injection pumps
IPC: F02D41/40
Filed: 1974-03-05
Abstract: 1413099 Automatic electric control of fuel injection FIAT SpA 5 March 1974 9848/74 Heading G3N [Also in Division F1] The injection time of a fuel injection pump is altered by physically changing its angular relationship with its drive-shaft in response to a sensed engine parameter by means of an hydraulically actuated helical sleeve coupling. In the arrangement shown the sensed engine parameter which may be engine speed, manifold pressure or temperature or composition of the exhaust gas produces an input signal to processor 24 whose output signal on line 32 represents the required angular displacement of pump drive-shaft 12 with respect to the driving-shaft 14. The actual angular displacement of shafts 12 and 14 is derived from the signals generated in pick-ups 38, 40 by ferromagnetic wheels 34, 36 which are used, after signal shaping in monostables 46, 48, to operate bi-stable flip-flop 54 and produce a signal on line 58. The error between the actual displacement and the required displacement appears as a signal on line 62 and is used in electromagnet 21 to operate valve 20 which alters the supply of hydraulic fluid to coupling 10 and thus the angular displacement of shafts 12, 14.
