Title: Improvements relating to paper roll holders
Inventor: BROWN LESLIE JEHU
IPC: A47K10/40
Filed: 1948-01-27
Abstract: 643,103. Roll holders. SCULTHORP & CO. (1934), Ltd., R. Jan. 27, 1948, No. 2418. [Class 18] An eccentrically weighted spindle for carrying a roll of paper or the like, and which is capable of only a limited rotational movement whereby only a limited length of paper can be withdrawn from the roll upon each pull exerted upon the outer end of the paper on the roll, is provided with a non-resilient radially adjustable member to enable it to receive rolls having cores of various internal diameters. The spindle comprises integrally formed body portion 8 and two end flanges 9, 10, one end flange 9 being of larger dimension than the other and each flange being provided with a boss which houses a pivot for mounting the spindle in the arms of a bracket 2. The radially adjustable member 25 is mounted on a screw 24 which engages in a boss 22 secured to the body 8 of the spindle, so that by adjustment of the screw the member 25 is moved towards or away from the body 8. The member 25 also engages a lug 19 provided on the body 8 to prevent relative rotation between the body and member. The lug supports one end of the pivot pin 13 projecting through the boss of the flange 10 which pin is spring influenced into engagement with one arm of the bracket. A finger piece 20 is attached to the pin 13 to facilitate the withdrawal of the pin to enable the spindle to be removed for the purpose of mounting a roll. When the spindle is in position with the roll mounted the finger piece is completely enclosed and unauthorized removal of the roll is prevented. Teeth 28 are provided on the member 25 to engage the roll of paper when it is mounted on the spindle and the body part is widened at one end as at 11 to ensure that the roll is securely engaged by the teeth 28. A stop 16 is provided on the flange 10 and engages a shoulder 17 on the corresponding arm of the bracket so that only partial rotation of the spindle is permitted. The weight of the body 8 returns the spindle to its initial position after each withdrawal.

Title: Ice eliminating system and oil separator operative therein
IPC: B64D15/16
Filed: 1946-01-24
Abstract: 621,497. Centrifugal separators. BENDIX AVIATION CORPORATION. Jan. 24, 1946, No. 2432. Convention date, March 31, 1945. [Class 23] [Also in Group XXVIII, XXIX and XXXIII] Air for use in an aircraft de-icing system, of the inflatable bag type 3, is cleared of oil and impurities by being passed through a combined cyclone separator and filter 10, or passed direct to atmosphere when not required in the bags. When passing through the separator 10, vanes 123 create whirl and cause oil and impurities to pass down a wall 35, past a ball-valve 239 to the inside of a tube 78 leading to atmosphere. The air passes up through holes 96, filtering material 97, holes 98, chamber 101, passages 102, 103 into an outlet 12 to a main pressure conduit 15 and through distributer valves 18 to the bags 3. A pump 6 takes air to be cleaned from a suction line 7. A solenoidoperated three-way valve is actuated by a switch 25 to place the separator 10 in the air circuit, the switch also causing the operation of a timer 20, which may be of the type described in Specification 621,464. When the solenoid 168 is energized, an armature 175 moves downwards and valve 125 is closed and a second valve 126 opened to allow air entering a passage 106, under pressure of the pump 6, to flow through a chamber 115, passages 116, 100 to the vanes 123. If the pressure in the line 9 exceeds a pre-determined figure, a valve 195 is forced open to allow excess air to pass to atmosphere by way of openings 190, 220 and 221. The downward movement of the armature 175 causes a ball valve 180 to open, allowing air in a chamber 149, above a diaphragm 145, to pass through a hole 183 to atmosphere. A spring 185 normally holds the ball valve closed. When the pressure in the chamber 149 is thus reduced, the air under pressure in passage 106 forces the valve 126 to a partially open position. The pressure then acts on the underside of the diaphragm 145 to complete the opening of the valve 126 and close the valve 125. Air pressure in chamber 149 is normally maintained by means of a small passage 160 from the space 106. When the de-icing system is not being used, the port 183 is closed to the chamber 149, through the ball valve 180, and the pressure in the chamber 149, plus the force of the spring 153, keeps valve 126 closed. This causes air from pump 6 to exhaust directly to atmosphere through conduit 78. Specification 621,490 also is referred to.

Abstract: 351,410. Vehicle fittings for loading and unloading ; endless chain conveyers. CARDWELL, S. O., Ribble Cottage, Hampton, Herne Bay, Kent, and BRIGHT & GALBRAITH, Ltd., 7, Martin's Lane, Cannon Street, London. Jan. 24, 1930, No. 2595. [Classes 78 (i) and 78 (iv).] In a vehicle provided with a movable floor of finite length which is adapted to be wound on a storage roller located at the rear of the vehicle, the end of the floor is detachably secured to the roller by a flexible connection in order that it may be run out of the vehicle when desired. The floor is composed of solid or tubular slats of wood or metal a or rods b which are hinged to one another at their ends by links c. The edges a<1>, Fig. 7, of the slats are rounded. The floor may consist of slats hinged together like a roller shutter with flaps over the joints to prevent the entry of moist sand into the joints. In a modification the hinge pins are of square cross section between the slats and are reduced to circular cross section at their ends, and the slats are of trapezoidal cross section. These floors may be used for conveying purposes. The floor is hinged to a baseplate h<2> which is connected to chains d passed round sprockets d<1> on shafts d<2>, d<3>. The storage roller e is drawn by an endless chain d<6> passed over a sprocket 4 carried by the shaft d<3> and also passed round a sprocket d<8> mounted on an idle guide roller d<9> for the floor. Rollers d<10>, d<11> also act as guides for the floor. Compression springs e<1>, Fig. 8, are arranged to exert a dragging action on the roller e. Laterallyprojecting lugs a<2> at the rear end of the floor engage lugs g' on the tailboard g and prevent rattling of the latter. The closure h at the front end of the floor is inclined upwardly and forwardly and is supported by brackets h<1> on the baseplate h<2>. A projecting arm h<3> on the closure h engages the tailboard g and raises it when the outward movement of the floor is near completion. The ends of the closure h are provided with scrapers h<4> to clean the sides B of the vehicle. The floor is driven by the propelling engine C of the vehicle when a lever k is actuated to put a worm l into engagement with a worm wheel on the shaft d<2>. The operation of this lever k releases simultaneously a lever m from engagement with a pin n on the baseplate. When the floor is run out or drawn in completely, a lug on the baseplate engages one of the stops o, o<2> on a tappet rod o<1> connected to the lever k and disconnects the engine. When it is desired to discharge at the side of the vehicle a shoot is bolted to the rear end of the vehicle body. This shoot may be provided with a conveyer belt coupled to the floor driving-mechanism. When the floor is disconnected from the roller e, it is run out on runners p, Fig. 5, hooked to the vehicle.

Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/52
Filed: 1933-01-27
Abstract: 414,087. Cigarette-making machines. WIX, A., 338, Goswell Road, and EDWARDS, W. F. M., 1, Kempsford Gardens, Earls Court, both in London. Jan. 27, 1933, No. 2677. [Class 130.] In a continuous-rod apparatus for the manufacture of filter-tip cigarettes, bores or receivers 1<a> in or upon an intermittently movable carrier 1 are brought successively into alignment with and between the outlet from a tobaccorod collector tube 3 and the inlet of a guide tube 4 by which the filling is led into a continuously formed paper tube. Lengths of filter-tip material are inserted in the bores or receivers before the latter come into position between the collector and guide tubes, and intermittent movement of the carrier is effected in timed relation to the rodforming apparatus, so that at each step a length of the continuous tobacco filling is removed and a corresponding length of filter-tip material is inserted. As shown, the carrier is a drum 1 mounted on a spindle 2 parallel to the axis of the tubes 3, 4. The drum is rotated intermittently by means of a rod 6 provided with a member 5 engaging pins 1<b >on the drum and actuated from a cam 7 through a swinging arm 8. After completion of its forward stroke, the rod 6 is turned, to disengage the member 5 from the pins 1<b>, by a cam-actuated slide 9 engaging an arm 6<a> on the rod, which is then returned by a spring 7b. While the drum is stationary, filter tips are inserted in the bores 1<a> from a tip-forming device 10 by a plunger 10<a>. When a bore moves into alignment with the tubes 3, 4, the tip therein is moved forward, with the tobacco rod in front of it, by a picker 15 mounted on a carriage 15<a> sliding on rods 16 and operated by a cam through a rod 15<b>. The rods 16 are carried by members 16b mounted on the upper ends of vertically guided rods 16<c> lifted intermittently by cams 17 acting through bell-crank levers 17<a>. The tobacco which enters the bore 1<a> behind the tip is severed on each side of the drum 1 by reciprocating cutters 13, 13<a> carried by a rod 13b operated by a cam 13<c> through a bell-crank lever 14, or rotary cutters may be employed. The tobacco remaining in the bore 1<a> is subsequently ejected by a plunger 11, or by an air blast or suction, and is discharged into a hopper or duct 12. The continuous filling, consisting of alternate lengths of tobacco and filter tip material, is enclosed in a continuous paper tube formed from a paper strip 18 led over the roller 19, and is cut into cigarettes by a final cut-off device. In place of the rotary drum 1, a reciprocating slide may be employed having two parallel bores or receiving tubes which are alternately in alignment with the tubes 3, 4 and receive lengths of filter-tip material from two separate positions, at which the lengths of tobacco filling carried away from the tobacco rod are also ejected.

Abstract: Methyl vinyl ketone is polymerized so as to obtain the polymer in the form of an aqueous dispersion by carrying out the polymerization in an aqueous medium which is a non-solvent for the polymer, in the absence of dispersing agents, the initial weight ratio of water to methyl vinyl ketone being at least 3 : 1 and preferably from 3 : 1 to 10 : 1.  The polymerization is preferably effected under an inert atmosphere such as nitrogen at a temperature of from 20 DEG  to 95 DEG  C. and in the presence of from 0.0005 to 0.002 parts by weight per part of methyl vinyl ketone of a polymerization catalyst, preferably a peroxy compound such as a persulphate or perborate of an alkali metal or of ammonium, or there may be used a redox system containing as reducing component a meta-bisulphite of an alkali metal or ammonium present initially to the extent of 0.0001 to 0.01 parts by weight per part of methyl vinyl ketone, or a mixture of ferrous ammonium sulphate and sorbose.  The polymerization may be regulated by the addition of 0.0001 to 0.01 parts by weight per part of methyl vinyl ketone of lauryl or butyl mercaptan or thio-glycollic acid.  At the conclusion of the polymerization the stability of the resulting dispersion may be increased by adding a dispersing agent or protective colloid such as sodium oleate, sodium dioctyl sulphosuccinate, cetyl dimethyl benzyl ammonium chloride, an oleic acid ester of a polyglycol ether, casein or polyvinyl alcohol.  The polymer may be obtained from the latex by formation of a film by evaporation of liquid from a thin layer, by addition of an organic solvent, such as acetone or ethyl acetate, in which the polymer is soluble, or by coagulating the latex by agitation by freezing and thawing, or by the addition of strong electrolytes.  The latex may be employed as an adhesive or as a box toe shoe stiffener, and alone or in conjunction with other materials such as starch, glue, gelatin and casein as a paper or textile size.ALSO:Textile materials, such as hosiery, lace, cheesecloth and cotton broadcloth are stiffened by treatment with a latex of polymerized methyl vinyl ketone (see Group IV (a)).

In a tuning arrangement for a superhet receiver including two resonant circuits L 1 , L 2 , each of which is tuned by a voltage sensitive reactor, such as capacitor diodes D 1 , D 2 , the bias on each diode is varied by potentiometers P 1 , P 2  so that the frequency difference between the resonant frequencies of the tuned circuits is maintained constant on adjustment of the sliders of the potentiometers by means of a single control knob. The potentiometers are constructed so that there is a linear relationship between the position of the slider and the resonant frequency. After the sliders have been angularly set #α apart to give the required frequency difference, f 2  - f 1  = f const. ; i.e. the intermediate frequency of the receiver, and with this angle #α maintained constant as the potentiometers are varied, the frequency difference is also maintained constant. The sliders can contact the resistive track of a single potentiometer.
