Abstract: 697,355. Abrasive cleaning of pipe couplings. McNICHOLL, G. E. May 12, 1952 [May 15, 1951], No. 11240/51. Class 60. An appliance for cleaning pipe couplings and other similar fittings, preparatory to the making of soldered or similar joints, comprises at least a pair of members adapted to be held together by an elastic band, split ring or the like so as to form a body possessed of a shank or shanks and a shoulder or shoulders for supporting detachable sandpaper or similar abrasive members, and a taper headed bolt axially located between the pair of members and operable by a wing-nut or the like for radially expanding the pair of members. The body of the appliance consists of members 1, 2 held together by an elastic band 3 housed in a groove 4 and forming an abrasive holder having a reduced end portion or shank 5. Pegs 6 on member 2 engage recesses 7 in member 1 for correctly locating the two members. Grooves 8 of semicircular cross-section in members 1, 2 together form an axial bore terminating in a taper portion at the shank end; a bolt 9 in the bore has a taper head 10 provided with a snug 11 fitting between the members 1, 2 so as to prevent rotation of the bolt. The bolt carries a wing-nut 12 and washer 13. Fitting on the shank 5 is a sandpaper or similar abrasive washer 14 on the back of which is a diametral flange 15 at right angles to the washer, the flange fitting between the members 1, 2. Clamped in the space between the members 1, 2 is one end of a rectangular piece of sandpaper or the like 16; when the shank 5 is inserted in the end of a pipe coupling-member 17, the sandpaper member 16 assumes a position around the shank, and upon rotating the wing-nut 12 the taper end of the bolt causes the members 1, 2 to expand and completely fill the interior bore of the pipe coupling. The appliance may then be rotated by an operative gripping the elastic band 3 whereupon the sandpaper members simultaneously clean the interior bore and one end of the pipe coupling. In a modification, Fig. 5, a shank 5 is provided at each end of members 1, 2 and the semicircular grooves 8 are flared at both ends; by reversing the bolt 9 the opposite shank may be used for supporting an abrasive member or members. The shanks are of different sizes for dealing with different couplings. In a further modification, both shanks are each of two different diameters.

Abstract: 288,827. General Electric Co., Ltd., (Briske, R.). April 28, 1927. Residual gases.-Filaments, especially of the spiral kind, are coated with a getter by bringing them into contact with a gettering fluid in a more or less completely exhausted vessel. They may be placed in a chamber 3 of a vessel 1, while a chamber 4 separated from the chamber 3 by a tap 2 is filled with the fluid, which may be of a known kind consisting of red phosphorus contained in a solution of collodion in amvl acetate. The chamber 3 is then closed by a plug 5 and exhausted through a tap 7. This tap is then closed, and the apparatus tilted up and the fluid admitted to the filaments. Atmospheric pressure admitted by an orifice 8 forces the liquid into the spaces of the filaments. The liquid is then drained back into the chamber 4, and the filaments are dried in the chamber 3 by exhausting the space therein. Surplus getter may then be washed from the filaments.

Class 100(i) Sheet-separators.-A system of levers and links for actuating the suction members of a sheetseparator device is controlled by a coupling member, which is associated with pivoted members and driven by a crank, comprising two spaced-apart plates between which are pivoted a rocking lever, a crank rod, and a member which rocks about a fixed pivot. As shown, a sucker bar 29, on.which suckers 30 are mounted for separating sheets from a pile, is actuated at each side thereof by a link 14 connected to a rocking lever 13 pivoted about a fixed axis 7. A coupling member 11 is pivoted to the lever 13 at 6, to a member 12 at 4, and to a crank rod 10 at 3, and comprises spaced plates which embrace the crank rod, member 12, and lever 13, these plates being spaced apart by collars on the pivot pins. The crank rod 10 is also pivoted at 2 to a rotatable crank disc 9 mounted at 1. The member 12 can swing about a fixed pivot 5, and is connected at 16 to a link 17 adapted to rock a lever 18. The lever 18 is connected through an adjustment device 34 to a link 19 which rocks the bar 29 and so tilts the suckers 30. The bar 29 is raised and lowered by a lever 31 which has a roller 32 bearing on a cam plate 33 rotatable with the crank disc 9. The construction of the coupling member 11 and the arrangement of pivots is such that bending moments in the system are decreased, and the tendency in the system to self-oscillation at very high speeds is reduced.

Filed: 1927-05-03
Abstract: 272,865. Sulzer FrÞres Soc. Anon. June 15, 1926, [Convention date]. Refrigerating, absorption machines for. - A continuous - system machine is provided with an auxiliary vessel communicating with the absorber and containing a mixture of liquid refrigerant and solvent so as to ensure the maximum concentration in the absorber. The auxiliary vessel 3, Fig. 1, is disposed below the evaporator coil 1 and communicates through pipes 4, 11 with the vessel 5 which communicates with the air-cooled absorber coil 6 and the circulating pump 8. In operation, liquid refrigerant and solvent flows from the condenser through the coil 1 to the vessel 3, the vaporized refrigerant passing through the pipe 4 into the vessel 5 and thence upwardly through the absorber coil 6 in counter-current to the weak liquor returning from the generator, to which the concentrated liquor is supplied by the pump. Liquid is passed periodically from the auxiliary vessel 3 to the vessel 5 by opening the manually-operated valve 12. In a modification, the flow of liquid from the vessel 3, Fig. 3, to the vessel 5 is controlled by a valve 20 which is automatically operated through links 17, 18 by a flexible diaphragm 16 subject to the pressure in the evaporator and to that in the vessel 14, which contains pure liquid refrigerant. Thus, when the vaporization temperature rises due to an excess of solvent in the auxiliary vessel, the refrigerant in the vessel 14 vaporizes and forces the diaphragm upwards so that the valve 20 is opened. In a modification, the auxiliary vessel is disposed above the evaporator coil.

Abstract: 594,772. Condensers. STANDARD TELEPHONES & CABLES, Ltd., LEE, E. C., and FEARON, J. H. June 23, 1944, No. 11956. [Class 37] An electric condenser of the rolled foil type is compressed to give a prescribed capacity value and then secured by a clamp, comprising at least one channel-shaped member. In an example, condenser units 15 are placed with a paper lining 16 in a lower channel element 12 which then receives an upper channel element 11 having tongues 13 in register with lugs 14 in the element 12. This assembly is dried at a temperature of 115‹ C. Œ 6‹ C. for 14 to 48 hours and placed in a cooling chamber for at least 4 hours at slightly above atmospheric pressure. The assembly is then compressed and subsequently clamped by folding tongues 13 over the lugs 14 when the capacity of the condenser attains a value which is predetermined by a linear relationship, to give the desired capacitance after impregnation. The assembly is then fitted in a container having small holes, for permitting impregnation and filling, which can be sealed by solder. Alternatively, impregnation may be effected before compression. In a modification, the elements 11, 12 are locked by fusing pips formed on the adjacent faces of their side walls. The pips may be formed on one element only. In another example, the condenser units are placed in a channel element as at 11 with a superposed metal plate which can be locked after compression by folding over slitted parts of the sides of the channel elements. An unslotted channel element may be used, tongues being punched in its side walls to lock the plate.
