Title: Bearing quality testing machine
IPC: G01M13/04
Filed: 1954-05-13
Abstract: 785,298. Electric control systems. FAR. MER, H. E. May 13, 1954 [June 2, 1953], No. 14005/54. Class 40 (1). A roller thrust bearing is tested by applying a gradually increasing axial thrust to one of the bearing races as it is rotated and measuring the torque necessary to effect rotation. If a predetermined torque is reached, indicative of a satisfactory bearing, the thrust may be automatically removed. As shown, Fig. 2, for testing a bearing 30 in a motor vehicle differential housing 28, the housing 28 is secured on an anvil 26 by retractable holders 32. A carrier 36 splined to a fixed column 24 for vertical movement therein, carries a constantly rotating quill 40 shouldered at its lower end to engage the inner race of the bearing 30. The carrier 36 and the quill are reciprocated vertically to rotate and apply thrust to the inner bearing race by a motordriven cam 56 acting through a follower pin 74, thrust rods 68, 70 and a compression spring 66 to limit the thrust. Circuitry and operation, Fig. 5. Depression of a start button 130 energizes a relay 120 which locks, releases a brake magnet 63 and energizes a clutch 64 through which a continuously running motor 58 drives the cam 56 to move the quill downwardly. The quill is continuously rotated by a three-phase motor 54 which through a current transformer 162, rectifier 154, and smoothing circuit 218, 220 biases a tetrode 92 positively according to the load on the motor. Through a potential transformer 164, rectifier 156 and smoothing circuit 210 a further adjustable bias is provided by a potentiometer 214 which is adjusted so that the tetrode passes sufficient current to operate a relay 90 at a predetermined. torque exerted by the motor 54, indicative of a satisfactory bearing. The relay 90 then releases relay 122 to de-energize the clutch 64, and apply the brake 65 to stop the cam 56. A meter 226 in the tetrode anode circuit indicates the torque or " bearing quality" and a signal lamp 228 lights when the predetermined torque is reached. A gauge 75, Fig. 2, operated mechanically in dependence on the downward displacement of the quill serves to indicate the number of shims. or the shim thickness required at the back of the bearing to bring it to datum position relative to the housing. The cam 56 is returned to its starting position by re-operating the button 130, the motor 58 being stopped in this case by a limit switch 131.

Abstract: 1,246,769. Automatic gripping devices for lifting girders. E. D. BUTZ. 23 March, 1970, No. 14033/70. Heading B8H. In a lifting device, Fig. 11, the grip of jaws 12, pivoted at 11 to a plate 10, is produced by the force applied to levers 15, 17 by lifting ropes 19 which also push abutments 24 into engagement with the top of the load through pinions 20 and racks 22. When the device is lowered on to the load upward movement of the abutments opens the jaws. In a second embodiment, Fig. 4, the jaws 107, 107a are connected to the vertically slidable abutment 115 by a cable 105. The jaws are automatically locked in the open position by abutments 131 and are released to close when a handle 130 is raised. Fig. 9 shows a further embodiment in which the upper ends of jaws 152, 152a overlap each other and each supports a pulley 157. The lifting rope 160 passes down and under one of the pulleys 157, up and over a rope guide 159 attached to the top of an abutment 153, as shown at 160<SP>1</SP>, down under the other pulley 157, and up as shown at 160<SP>11</SP>. An automatic latch 168 holds the jaws open until it is manually released. (For Figures see next page.)

Abstract: 744,072. Cementation. WALKER, R. M., and MILLER, A. M., [trading as WALMIL CO.]. May 19, 1953 [May 19, 1952], No. 14072/53. Class 72. A method of controlling the carbon content in surface layers of ferrous articles comprises providing an enclosed space about the surface, providing within the enclosed space a dry, rigid, self-supporting body of an oxidising-decarburising agent and an inert binder, and heating the articles to the reaction temperature. The rigid body may comprise iron oxide and clay. In a casehardening operation the rigid body prevents case-hardening of the protected surface, and in the heat treatment of a high carbon steel article the carbon content of the protected surface may be reduced, the amount of reduction may be controlled by varying the size or number of the rigid bodies. As shown, applied to the case hardening of the outer surface of an annular ring, the ring 32 is placed on a support 34, a rigid body 38 is placed within the ring, and a cover 36 laid on the ring. When the ring is case hardened the surface 30 is protected against carburising and remains soft. The shape of the rigid body may be varied to suit the shape of the surface to be protected.

Abstract: 1490211 Adjusting vehicle headlamps LUCAS ELECTRICAL Ltd 13 March 1975 [30 March 1974] 14220/74 Heading F4R Vehicle headlamps are mounted on a rod 16 extending transverse to the vehicle body so that rotation of the rod about its axis effects tilting of the headlamps in a vertical plane in response to changes in attitude of a suspended part of the vehicle, the tilting mechanism including spring arms 24, 25 each secured at one end in relation to rod 16, the other end of arm 24 engaging abutment 27 and the other end of arm 25 being biased by the remainder of the tilting mechanism in the direction such that arm 24 is stressed, changes in the biasing of arm 25 being partially absorbed by balancing of the stresses in arms 24, 25. The effect is to reduce the signal transmitted to the rod as compared with arrangements having a more rigid lever between the rod and actuating means. Moreover the extent of the reduction can be varied by adjusting abutment 27. As shown the means for sensing changes in attitude includes cable 18 secured at its other end to an unsuspended part of the vehicle, the effective length of the cable varying with loading. Pendulum 32 having damping means 33 responds to changes caused by acceleration or deceleration.

IPC: C08F279/02
Filed: 1959-04-27
Abstract: Ethylenically unsaturated monomers are polymerized in the presence of rubber by a process in which a high viscosity dope comprising a dispersion of a rubber in a preferably partly polymerized matrix of monomer, which dope has a total polymer content of from 15 to 35% by weight, is dispersed in water containing a suspension stabilizer by means of a stirrer having two or more blades one of which is situated just below the surface of the liquid so as to provide additional turbulence at the top of the reaction mixture, and the aqueous dispersion so obtained is then polymerized.  As a monomer there is specified styrene, which may be used alone or in admixture with other monomers such as acrylonitrile or methyl methacrylate.  The rubber may be natural or synthetic, e.g. a butadiene/styrene copolymer.  The polymerizable dope may be made by dispersing rubber in monomer, rubber in a mixture of monomer and polymer or, most preferably, by prepolymerizing a dispersion of rubber in monomer.  The p polymerization of the dope may be carried out with the aid of catalysts such as benzoyl and lauroyl peroxides and mixtures thereof, and a mixture of azobisisobutyronitrile, benzoyl peroxide and lauroyl peroxide.  As a suspension stabilizer there is specified polyvinyl alcohol.  The resulting products may be submitted to hot milling or mastication as described in Specification 924,873.
