Title: Improvements in lubrication systems
IPC: F16N7/30
Filed: 1934-11-30
Abstract: 453,216. Lubricating-pumps; forcing liquids by gas pressure. PRUVOT, H. F. N., 54, Rue FrÚdÚric Mestreau, Saintes, Charente- InfÚrieure, France. Nov. 30, 1934, No. 34478. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 31, 1935]. [Classes 102 (i) and 102 (ii)] [See also Group XXXIV] Lubricators supply given amounts of oil to the parts to be lubricated under the action of pulsations in the oil supply, these pulsations being generated at a frequency proportional to the speed of the machine being lubricated ; the invention relates also to the construction of lubricators, and to the means for generating the pulsations. In the system shown in Fig. 1, lubricators 5, 6, 7 supplying oil to the parts 1, 2, 3 are connected by a main pipe 8 with the oil container 4 ; a mechanical pulsator 9 and a hand-operated pulsator 10 connected in series generate pulsations in the oil in the pipe 8 ; the operation of the system is observed by means of " optical apparatus " 32. Each lubricator comprises a differential piston 15, 16, Fig. 2. The portion 15 works in a cylinder 13 communicating with the atmosphere through a duct 23. The portion 16 works in a cylinder 14 which is supplied with lubricant through a passage 22 having a port 28 ; this port is closed by the piston 16 during its forward motion, and oil is then delivered through a discharge passage 24 having a spring-pressed ball valve 26. The differential piston is urged by a spring 18 against a stop 19; a screw 29 limits the forward stroke. The operation of the device is checked by a needle valve 31 in a duct 30. To generate the pulsations, compressed air from a source 36, Fig. 3 is admitted through the valve 37 to the space above the lubricant in the container 33 ; the valve 37 is then closed and the space above the lubricant connected through valve 38 with a chamber 39 in communication with the atmosphere through a spring pressed valve 40 ; the space is thus exhausted to a pressure slightly greater than atmospheric. The valves 37, 38 are alternately actuated by cams 41, 42 on a shaft 43 driven by the machine to be lubricated. By means of a three-way valve 44 the space above the lubricant can be connected with a hand-operated pulsator.

Title: Method and device for the manufacture of pressed boards from particles, such as wood shaving or similar particles, provided with bonding substances
IPC: B27N3/22
Filed: 1961-09-27
Abstract: <PICT:0917255/IV(a)/1> <PICT:0917255/IV(a)/2> <PICT:0917255/IV(a)/3> A method for the manufacture of pressed boards from wood particles provided with bonding substances comprises the steps of scattering particles on to a base to form a blank, slipping the base and blank between the platens of a press, after which before the press is closed the supporting base is withdrawn from under the blank and the latter is deposited on the lower plate of the press.  In one embodiment of the invention chips are spread on a rigid supporting base which is then inserted between press platens.  A stopping plate is then brought into action as the supporting base is withdrawn back towards the blank forming station.  The leading edge of the supporting base may have an air jet mounting to sweep the press platens clean during loading.  In a second embodiment the supporting base is flexible and, after the blank has been formed, the base passes through the press and the base is withdrawn by moving it on in the same direction.  In a third embodiment the blank is made by scattering on an endless belt of a transport device which is then inserted in the press.  The device is then withdrawn from the press whilst the belt is made to run at the same time, the direction of motion and the speed of the belt being chosen so that the upper surface of the belt remains motionless in relation to the press.  In a fourth embodiment a multi-daylight press is used together with a multi-layer loading device.  Details of the blank-forming, loading and base-plate removal are given.  It is stated that during the removal of the supporting-base from under the blank, the blank remains in position under the press due to its own inertia.

Abstract: 509,245. Centrifugal machines ; testing yarns &c. FORSTER. R. B., UPPAL, I. S., and VENKATARAMAN, K. Dec. 16, 1937, No. 34810. [Class 23] [Also in Group IX] The wetting power of textile auxiliaries and the like are determined by the immersion of a known weight of suitable textile material for a definite time, the material being weighed again after it has been centrifuged. The apparatus permits the textile material to be immersed by the swinging of the centrifuge spindle A which is mounted on an axle B. In its vertical position it can be connected by a mechanically or magnetically operated coupling C to the driving motor, which is preferably an alternating current synchronous motor. The time of the centrifuging action is controlled by a screwed nut D travelling along the spindle A. At the commencement of operations, the motor rotates the spindle to carry the nut to its upper limit to open the circuit-breaker E. The weighted textile material is suspended from the hook F and immersed in the liquid under test by the swinging of the spindle A on the axle B ; this movement releases the circuit breaker and actuates a reversing switch. The immersion continues for a prescribed time, during which the motor runs up to speed. The material is removed from the liquid by the swinging of the spindle to the vertical position, and the motor rotates the spindle through the coupling C to centrifuge the material on the hook F. This action lasts while the nut D travels downwards and the projection G depresses the lever H to disengage the coupling C.

Abstract: 581,399. Taper roller bearings. BRITISH TIMKEN, Ltd., and McNICOLL, D. Dec. 24, 1945, No. 34889. [Class 12 (i)] In a taper roller bearing the cage has at one end a ring or annular flange 7 which overhangs the thrust flange 2 of the cone and has the other end formed to releasably interlock with the cup 4. The cage carries resilient roller-spacing arms 8, extending from the ring in conical formation and passing between the rollers 3 substantially parallel to the race surface of the cup 4, these .arms having their free ends turned up to form tips 9 which engage with the cup 4 by a spring snap action when the cup is moved axially into position over the rollers. The width between the free ends of the arms 8 is such that the ends normally retain the rollers, but can be sprung apart by endwise force applied to the rollers to permit the removal of the rollers. The larger end of the cone 1 is externally bevelled around the outer wall of the rib 2 at 5, to correspond with the cage ring 7, and, at the opposite end of the bearing, the larger end of the cup 4 is internally bevelled at 6 to correspond with the lips 9 of the cage. The bevelled end surface 6 will depress the lips 9 sufficiently to clear this surface, so that the bearing members can be readily separated. The cage can be made from a flat sheet-steel blank. A double-row taper bearing assembly has an annular recess 12 between two cups 4. In a modification, the arms of the cage may have at opposite sides lateral wings with edges bevelled or shaped to engage and overlap the rollers. The arms are joined to the end ring of the cage by neck portions, thus forming pockets of substantially H-shaped.
