Title: Improvements relating to anti-friction bearings
IPC: F16C37/00
Filed: 1944-11-01
Abstract: 592,947. Bearings. ARMSTRONG SIDDELEY MOTORS, Ltd., and HEPPNER, F. A. M. Nov. 1, 1944, No. 21406. [Class 12 (i)] The cage of a ball or roller bearing serves to deliver oil to lubricate the balls or rollers and also to deliver, in parallel flow, oil for cooling the bearing, the latter flow thus by-passing the balls or rollers. The invention is shown applied to a high-speed rotor mounted on a fixed hollow shaft 13 by a two-row angular-contact ball bearing 16. The fixed hollow shaft 13 contains an oil supply pipe 17 from which oil passes by ducts 24, 25 in a body member 18 protruding through the shaft 13 and also through the inner (fixed) race 12 of the ball bearing to a collecting groove 26 on the under-side of each of the ball cages 14, 15. From this groove a quarter of the oil passes to a single duct 27 opening adjacent the lower end 11a of the ball track of the outer race 11, while three-quarters of the oil passes to three ducts, such as the ducts 29 shown for the cage 15, spaced 90 degrees apart and extending through the cage 14 to open at the further edge of the cage. Thus one-quarter of the oil serves for lubricating the balls and tracks while threequarters of the oil passes merely as a cooling flow direct to a collecting space 31 receiving both the oil flows. The oil passes from the collecting space 31 by a duct 34 to a middle channel 19 on the under-side of the outer race, whence it is withdrawn by a fixed scoop, as described in Specification 592,948, projecting from the body member 18 and passes away by the hollow shaft 13. The collecting groove 26 in the cage has an abutment to compel the oil to rotate with the cage. Specification 561,246 is referred to in the Provisional Specification.

Title: Improvements in and relating to speed regulating mechanisms for prime movers
IPC: G05D13/00
Filed: 1933-07-31
Abstract: 422,579. Speed governors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Caughey, R. J. ; 910, Livingston Avenue, Schenectady, New York, U.S.A.) July 31, 1933, No. 21493. Convention date, July 29, 1932. [Class 57] A speed governor 10 controls the regulating valve 7 of the prime mover through a fluid relay 12. A control valve 51 is connected to the control valve 30 so that during normal running its face 49 just uncovers a port 53 leading to a spring loaded piston 44 allowing pressure fluid to enter the cylinder and maintain the piston 44 in its lower position. Upon an excessive rise in speeds the control valve 30 is lowered and upon a certain predetermined movement being exceeded, the face 49 uncovers the port 53 allowing exhaust to port 56 with a consequent rising of the piston 44. Connected to the piston 44 is a double valve 41 which when in the lower position allows fluid to flow from pipe 39 to pipe 43 and cylinder 36 maintaining in its lower position a spring- loaded piston 35 also connected to the regulating valve 7. The rising of the piston 44 tends to seat the upper part of the valve 41 and also open the pipe 43 to exhaust and allow the piston 35 to rise and accelerate the closing of the valve 7, the acceleration depending upon the amount of opening of the port 53. In an alternative construction the governor actuates the control valve of the fluid relay through an auxiliary fluid relay. The main fluid relay is supplied by two pumps, one of which is brought into action by a valve actuated by the piston 44 to increase the fluid pressure and accelerate the movement of the power piston to close the valve 7. In a further construction the power piston of the main fluid relay is of a differential type and the piston 44 actuates a valve to release the pressure on the larger area and accelerate the movement.

IPC: G05G7/04
Filed: 1958-07-04
Abstract: 863,512. Linkwork. NEATE BRAKE CONTROLS Ltd. June 16, 1959 [July 4,1958], No. 21524/58. Class 80 (3). [Also in Group XXXIV] In a, vehicle hand brake control mechanism, [Group XXXIV], provision is made for increasing the mechanical advantage during brake applying movement of the operating lever so that a relatively low applied force is applied to take up the slack in the transmission linkage to the brakes and an increasingly larger applied force is introduced as the operating lever is extended to its fully applied position. The hand-brake control mechanism illustrated comprises a lever 1 pivotally mounted about a fixed axis 2 and provided with a normal retractable pawl 5 and ratchet mechanism 4 which serves to hold the brake lever in any desired position of adjustment. The other end of the brake lever 8 is provided with a pivotal connection with a floating intermediate lever member 10 which has pivoted thereto at 18 a connecting member 11 of a brake control rod 12. A cam member 13 is fixedly mounted in the mechanism and is arranged such that when the lever 1 is moved from its fully " off " position shown in Fig. 1 to its intermediate position shown in Fig. 2, the point of contact of the cam member 13 with the cam surface 15 slides nearer the end stop member 16 of the lever member 10 to apply movement to the brake rod at a minimum mechanical advantage. As the brake lever 1 continues its movement towards its fully " on " position the mechanical advantage is increased as the fulcrum point moves progressively away from the point of pivotal connection 18 to the brake rod 10.

Title: Materials for inhibiting production of undesirable products on body surfaces and environs
IPC: A61L15/46
Filed: 1975-05-22
Abstract: When microorganisms form the said fatty acids by breaking down lipoid materials which are present in body secretions such as, for example, sweat, menstrual fluid and the like, then an unpleasant odour is produced. On the other hand, if the microorganisms which are intrinsically harmless are killed, there is a risk of colonisation by dangerous microorganisms in their place. The products according to the invention, for example cosmetic products such as deodorants, sanitary menstrual products and the like, now contain as active ingredient a salt of ethylenediaminetetraacetic acid. Although this prevents the unwanted breakdown of the lipoid materials by the said microorganisms, the viability of the microorganisms is not impaired. Preferred salts in this connection are the alkali metal salts, especially sodium salts, or alkanolamine salts, especially trialkanolamine salts, of ethylenediaminetetraacetic acid.

Abstract: 354,043. Intercommunication systems. COVENTRY AUTOMATIC TELEPHONES, Ltd. and TWEATS, J. A., of General Electric Co., Stoke, Coventry. July 24, 1930, No. 22316. [Class 40 (iv).] In a system in which master stations MA, MB are equipped with loud-speakers and sensitive microphones and with ordinary receivers, minor stations S4 .. S3 having instruments of ordinary type, means are provided at the master stations for varying the efficiency of the receiving equipment in accordance with the type of station with which communication is being effected and with the type of receiver being employed. For example, when the distant station is a minor station resistance or an alternative induction coil may be cut in or, as shown, the connections of the existing induction coil are rearranged (except when the loud-speaker is in use) to reduce its efficiency. Alternatively the normal circuits may be inefficient and the efficiency may be improved when communication is with another master station. As shown, conversation with a minor station involves the closure of a contact such as s on the keys MAS4, MAS2, &c., and conversation with another master station involves the closure of a contact m on a key such as MAM. With the switch-hook down, the loudspeaker L receives incoming currents at full strength from either kind of station. With the switch-hook up however the loud-speaker is disconnected and if the distant station is a master station, signals are received at medium strength through the windings J2, J3 of the induction coil. If the distant station is a minor station however, signals traverse the coils J4, J2 in opposition so that the signals received in J3 are much reduced. An impedance may be inserted at X to equalize the strength of signals received on the loud-speaker from the two types of station. Alternatively an amplifier may be inserted at Z where it amplifies only signals received on the loud-speaker or at Y where it amplifies currents for the receiver as well as the loud-speaker. Establishing calls. A minor station calls a master station by removing his receiver and pressing one of the keys S4MA, S4MB, &c., operating a visible signal such as MAJ4 which operates the buzzer &c. MAZ. The call is answered by pressing the key MAS4, MAS2 corresponding to the calling station. A master station calls another by pressing a key such as MAM. The corresponding indicator at the other station drops and energizes the buzzer and the key MBM there is then operated to establish the talking circuit.
