Title: Improvements in brushes
IPC: A46B5/02
Filed: 1936-08-12
Abstract: 485,185. Brushes; mats. STEINMETZ, S., STEINMETZ, A., and BAUMANN, J. Aug. 12, 1936, No. 22179. Void. Convention date, Aug. 22, 1935. [Class 19] [Also in Group IX] Bristles on brushes and brush mats are replaced by strips of rubber, preferably formed from worn rubber tyres. The strips are preferably removable to eliminate the deposit of dirt. In a washing or scrubbing brush, Fig. 1, rubber strips b are folded into dovetail grooves c of a brush stock and secured by wires d suitably clipped in place. The strips may be notched at the edges. On withdrawal of the wires d the strips may be renewed. Unfolded cemented strips may be used. In a modification, Fig. 6, the brush stock may be hinged and used as a roll up mat. Where the brush is used as a mat, Fig. 8, rubber strips b are disposed in socket members a connected to a flexible support a<1>. The mat can be rolled up and dirt removed from depressions a<11>. Fig. 9 shows a double-sided foot mat. Fig. 10 represents a rotary washing brush with a passage h for water. In another modification, rubber elements b, Fig. 11, may be mounted in a disc a.

Abstract: 1364793 Sintered composite metallic annular bodies FEDERAL-MOGUL CORP 11 May 1972 [14 June 1971] 22211/72 Heading C7D [Also in Divisions B3 and F2] A composite bushing 12 for plain or rolling bearings is made from inner and outer briquettes 48, 46, respectively, of different powdered metallic materials said briquettes being assembled telescopically, sintered to form a composite body, heated to a suitable hot-forging temperature, and then hot-forged to cause some intermixing of material across the interface 14 to lock the briquettes together. The briquette which is to provide the load-bearing surface is made from a high performance iron alloy such as S. A. E. 4600 alloy powder or a nickel-free manganesemolybdenum iron alloy powder; the other briquette is made from iron powder. The hot-forging process causes the outer end portions of the briquette 48 to deform into contact with the bevels 50 of the other briquette 46. In an alternative embodiment Fig. 5 (not shown), the bevels are formed on the inner, rather than the outer, briquette.

Title: Improvements in rotary electric machines
IPC: H02K17/24
Filed: 1959-07-01
Abstract: 875,768. Induction machines. ATLAS COPCO A.B. July 1, 1959 [July 5, 1958], No. 22579/59. Class 35. A rotary A.C. machine having a stator 1 and a main rotor 2 both with windings fed from an A.C. network and a squirrel-cage rotor 3 radially or axially disposed between them, the pole number of one of these members being variable, acts as a motor or generator with a high synchronous speed, the main rotor running at a speed higher than that of the intermediate rotor. With a 50-cycle supply the synchronous speeds are 6000 and 4500 r.p.m. respectively for 2-pole and 2-4-pole machines respectively. The 2-pole machine runs as a synchronous motor and the 2-4-pole machine as an induction motor at less than synchronous speed. Rotor 3 serves as a secondary circuit for both stator and main rotor windings and as a damper winding against main rotor oscillations. Owing to the magnetic coupling between the circuits minimum torque occurs at 4000 r.p.m. for the 2-pole motor. To overcome this effect, inductive or capacitive elements 11, 12 may be switched in the stator and main rotor circuits by switch 13 during acceleration (Fig. 2, not shown). To avoid subharmonic currents in stator and rotor windings by pole changing they may be given different numbers of poles during acceleration. A motor may accelerate to 4500 r.p.m. as a 2-4-pole machine and then by operating switch 14 to 6000 r.p.m. as a 2- pole machine. By short-circuiting the main rotor winding by switch 15, the machine may run as an ordinary induction motor with a speed somewhat less than 3000 r.p.m.

Title: Improvements in the catalytic cracking of hydrocarbon oils
IPC: C10G11/18
Filed: 1954-08-06
Abstract: <PICT:0761501/III/1> In a process for the catalytic cracking of heavy hydrocarbon oils employing the heat-balanced fluidized catalyst technique, hot gas oil separated from the cracked products is cooled and then mixed with hot regenerated catalyst to produce a suspension of catalyst in oil vapours having a temperature above the cracking temperature (but not above 1050 DEG F.); this suspension is passed through a transfer line into the bottom of the fluidized catalyst bed in the reaction zone; and the fresh feed oil, preheated to a temperature below the cracking temperature, is separately introduced into the bottom of the fluidized catalyst bed, wherein the two streams intermingle to produce a suspension of catalyst in oil vapour at the cracking temperature.  The process produces good quality gasoline, and obviates overcracking of the feed. The relative depth of cracking may be varied by the amount of cooling and heating, respectively, of the two streams fed to the reaction zone.  The apparatus shown comprises a preheating furnace 9, a reactor 2, a product fractionator 6 to which are connected sidestrippers 7 and 8, a cooler 10 connected to the lower end of a riser 5 which leads up into the bottom of reactor 2, and a regenerator 1 which is connected to the lower end of riser 5 by standpipe 3.  Gas oil at 600 DEG F. removed from the sidestrippers is passed through line 14 to cooler 10 where it is cooled to 180 DEG F. This recycle gas oil is then introduced into riser 5 where it mixes with regenerated catalyst at 1100 DEG F. from standpipe 3 to form a suspension of catalyst in oil vapours at about 1000 DEG F., which flows up the riser to reactor 2. Virgin gas oil is preheated in furnace 9 to 740 DEG F., and is then discharged through line 15 into the reactor at the top of riser 5. The feed rate ratio of virgin gas oil to recycle gas oil is 2:1; and the temperature of the mixture where it mingles with the fluidized bed of catalyst in reactor 2 is about 900 DEG F.  A pressure of 11 p.s.i.g. is maintained in the reactor.  The product vapours, issuing from the reactor through line 11, are passed to fractionator 6. Gasoline and gases are withdrawn from the head of the fractionator, and gas oil fractions are taken off into side-strippers 7 and 8. Spent catalyst leaves reactor 2 through line 4, and is regenerated in regenerator 1 which is maintained at a pressure of 16 p.s.i.g.
