Title: Improved bearings and methods of making the same
IPC: F16C33/14
Filed: 1939-10-12
Abstract: 536,414. Making compound bearings. GENERAL MOTORS CORPORATION. Oct. 12, 1939, No. 27704. Convention date, Oct. 24, 1938. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXIV] Angular beading ; die-rolling :-A bearing is formed by a matrix 14 consisting of copper, silver, or a moderate antifriction alloy thereof capable of supporting heavy loads having regularly disposed spaced indentations 44 filled with soft bearing metal of good antifrictional properties such as babbit consisting of 95 per cent lead and 5 per cent tin. The indentations 44 preferably do not extend completely through the matrix, the rear surface of which may be thermally bonded to a steel back 12. The bearing may be made by thermally bonding the copper or other lead bearing material to the steel back by pouring molten copper on the steel back or byepassing steel strip through a reservoir containing molten copper in a non-oxidising atmosphere and subsequently either pressing the bimetallic strip to the matrix form between dies or passing it as shown in Fig. 9, between rolls 22, 24 into contact with a die 26 shaped to give the desired curvature. The matrix is next coated with a flux and molten bearing material applied. The bearing is then machined to its final dimension, portions of the matrix 3 being exposed. Automobile bearings may have a babbit thickness of from 0.005 inch to 0.010 inch with a maximum grid thickness of 0.034 inch secured to a steel back of 0.016 inch thickness. The exposed surfaces of the bearing surfaces may be in the ratio of 60 40, either surface predominating. The Specification as open to inspection under Sect. 91, states that the copper, silver, or like bearing surface may be formed with longitudinal or spiral ribs and the spaces between the ribs filled with soft metal, when the bearing is cylindrical the ridges may be formed by drawing a broach through a cylindrical blank, or spiral grooves may be cut in the blank by a lathe. This subject-matter does not appear in the Specification as accepted.

Filed: 1945-10-22
Abstract: 599,051. Signalling over power circuits. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. Oct. 22, 1945, No. 27742. [Class 40 (iv)] [Also in Group XL] An electrical filter circuit for use in a ripple control system wherein a ripple generator 5 feeds control current to an alternating current power line 6, comprises a condenser 8 and an inductance 7 in series with the generator, and an inductance 10 fed from the line through a balancing transformer 9 and connected in parallel with inductance 7. The effect of the net. work is that the power current in the line cannot produce a voltage across the inductance 7 and generator 5 and thus there is no feedback of power current to the ripple generator. A few cross-connected turns 12 are provided in the transformer to correct slight phase displacement due to losses.

[Classes 18 and 94(i)] An apparatus for erecting boxes from and breaking the creases of pre-cut and pre-creased blanks comprises a former adapted to press on the box bottom panel to force it through an open bottomed die having means thereon to turn up end and side walls in sequence, and means for removing the formed box from the former below the die. The embodiment described includes means for breaking creases at the edges of a lid panel 29 and a front wall panel 22 of a blank. The blank, one of a succession, is fed from a hopper to the first position A, Fig. 1, on a table 32, Fig. 4, where it may be held by guide rods (not shown) and is advanced to the second position B by a longitudinally reciprocating rod 33 carrying pawls 40-42 which engage the blank. At the position B the lid panel 29 is pressed by a platen 35 and the bottom panel 21, end walls 24 and rear wall 23 and its extension 26 are all covered by a body platen 45. Fingers 43, 44 advance arcuately through openings in the table 32 to bend flaps 30, 31 of the panel 29 against the sharp edges of the platen 35. The wall 22 is bent onto the platen 45 by a similar finger 46. Their creases broken, the flaps bend back under their own resilience but the wall 22 is held in a rearwardly inclined position by a bar 65, interposed following the operation of the finger 46. The blank is fed to position C, where a platen which may be integral with the platen 45 again covers parts 21, 24, 23, 26, the wall 22 having entered a guide member 74. A finger 77 breaks the crease between the panels 29 and 23 and the blank is fed forward onto the die 38, Fig. 7, the member 74 positioning it in one direction and arms 87 which descend to engage opposite sides of the lid, positioning it in the other, the lid having been brought to a vertical position by a guide bar 121. A former 91 presses the blank downwardly when portions of the die 38, first fold up the ends 24, then side wall extensions 25, 26 on to the ends 24. Slots 28 in the walls 24 are opened to receive tongues 27 on the extensions 25, 26 by buttons 98 on the former 91 which press the material beneath the slots outwardly and fingers (not shown) on the former arms 92 pressing the material above the slots inwardly. Stripping fingers 108 operated by levers 110, 111 and gearing 112 from the shaft 95 remove the boxes to deposit them on a conveyer. The platens 35, 45, creasing fingers 43, 44, 46, 77 and positioning arms 87 and bar 65 are operated through levers and cams from a main driving shaft 64, the fingers 43, 44, 46, 77 being turned about their pivots 50 by a single crosshead 54. The speed of rotation of the formers may be varied to give a rapid traverse between forming operations. The Provisional Specification states that the body platen may remain permanently depressed and that the fingers opening the end wall slots, may be carried by the die; also that the stripper may be within the die.

Title: Improvements in or relating to electro-magnetic relay devices
IPC: H05B39/10
Filed: 1924-11-24
Abstract: 249,583. Scherer, B. Nov. 24, 1924. Controlling lighting systems.-An automatic electromagnetic contactor-relay, for an automobile lighting installation, comprises two armatures 1, 2 under the control of two springs r, r' of which r<1> is the stronger, the armatures being adapted when attracted under the action of differential windings s, s' common to both of them to close and open, respectively, two circuits c', c<2>, both allowing, when closed, an auxiliary lighting circuit p' to be brought into use in case of fault in the main circuit p. The winding s, which is a resistance winding through which the auxiliary small battery a<1> is charged, in parallel with the main battery a, from the generator g, has a large number of turns and is connected to the frame of the electromagnet at one end and to the small winding s', through a fuse f, at the other. With conditions normal and the lighting circuit p in operation, the charging current through the winding s causes it to preponderate over the winding s' and to attract the armature 2 against the action of the weak spring r, thereby opening the auxiliary circuit at c<2> and maintaining it open. In the event of excess voltage causing destruction of the main lamps, the armature 1 is attracted and the auxiliary lamp circuit closed. If the fuses f or f<1> melt, both armatures are released and the auxiliary lamps will be fed from the auxiliary battery. In the event of a short-circuit of the main lighting circuit both armatures are attracted and the auxiliary circuit is closed.

Abstract: 535,822. Crank-case ventilation; treating charge. DONALDSON CO., Inc. Oct. 18, 1939, No. 28166. Convention date, Sept. 11. [Class 7 (ii)] In a system using engine suction to effect forced crank-case ventilation, adequate ventilation under all engine load conditions without mixture composition disturbance at idling speeds due to excessive additional air is automatically effected by a flow regulating device 41 mounted between the crankcase 23 and the induction pipe 24 downstream of the carburetter, either within the crank-case cover 36 or in an intervening pipe 39. The device 41 comprises a valve body 51 progressively lifted in accordance with engine suction increase to bring a valve surface 50 closer to its seat. Flanges 53 prevent complete flow cut-off at high engine suctions, and feet 52 prevent the body 51 blocking the entry to the device at low suctions. As shown, an oil trap 54 is provided, but where the device 41 is within the cover 36 it may in itself act as such. The crank-case may have a filtered breather, or may draw air from the engine induction system upstream of the carburetter and preferably downstream of an air cleaner. Specification 497,888 is referred to.

Abstract: 1,179,956. Silica sol. VEREINIGTE PHOSPHATDUNGERWERKE VEB. 19 June, 1967, No. 28186/67. Heading C1A. A silica sol is produced by continuously circulating a solution which initially consists of acidic silica sol, dilute acid or salt-free water, through a cation exchanger initially in the H<+> form and through a separate mixing device and adding an alkali metal silicate solution at said device. Anion exchangers are preferably incorporated in the circuit downstream of the cation exchanger. The alkali metal silicate is added in an amount which ensures that the critical pH of 4À5 to 7, which causes gelling, is not reached. A pH value of 2-3 is advantageously maintained in the reaction solution before and during the exchange reaction. Fixed beds of ion-exchangers are used. The regeneration of the ion-exchanger is preferably carried out in a stepwise manner so that in the course of a regeneration cycle the regeneration agent is divided up into several fractions which are successively reacted with the exchanger. The first fraction is discarded after the regeneration process and the following fractions are temporarily stored after the regeneration process and in the next cycle used for the preceding regeneration stage so that for the cycle in question only a part of the otherwise necessary amount of regeneration agent is required as a fresh solution in the last stage.
