[Classes 6 (i) and 6 (iii)] A wheel-operated lifting device, having a crank 19 driven from the land-wheels (not shown), through differential gearing 4, 6, 8, 9, comprises two crownwheels, 4 and 9, coaxially mounted on the crank shaft S and interconnected by bevel pinions 6 carried by a third coaxial wheel 8. The first crown-wheel is loose on the shaft 5, and is in constant mesh with gearing 3 on the land-wheel axle 1 ; the second crown-wheel is keyed to the shaft and is formed with half-revolution recesses 10 enabling it to be locked in either of two positions by a lever system which locks either the wheel 8 and frees the wheel 9, or vice-versa. The bevel pinions 6 are carried on spindles 7 mounted in the body of the wheel 8, which is also free on the shaft S and has peripheral ratchet teeth which can be engaged by a pawl 15 pivoted on a shaft 13. The pawl is free on the shaft 13 but is connected by a spring 16 to a lever 12 having a roller 14 which enters the recesses in the crownwheel 9, the arrangement being such that the pawl 15 is disengaged from the ratchet-wheel 8 when the roller 14 locks the wheel 9, and vice-versa. The lever 12 is fixed to the shaft 13, which can be rocked by a spring-loaded lever 29 connected by rod to a control lever at the front of the machine. Inter-engaging abutments 17 and 18 on the levers 12 and 15 prevent the pawl 15 from locking the wheel 8 immediately the crown-wheel 9 is freed ; a certain amount of free rotation of the wheels being thereby permitted. The crank 19 is joined by a rod 20 to a lifting lever 21 connected to the lifted part (not shown) by a pivoted quadrant 22 and chain 25.

Title: Expanded resinous materials
Inventor: CRAM DONALD JOHN
IPC: C08J9/06
Filed: 1961-02-14
Abstract: A process for making expanded nylon-11 comprises forming a mixture comprising powdered nylon-11 and a powdered blowing agent and heating the mixture to a temperature at which the blowing agent decomposes. The heating may be effected in a mould, in which case the decomposition temperature of the blowing agent is selected to have a value of 10-50 DEG C. above the melting point of the nylon-11. The process may also take the form of coating a metal object by heating it to a temperature above the decomposition temperature of the blowing agent and dipping it into a mixture of powdered nylon-11 and powdered blowing agent. In examples (1) a mixture of nylon-11 (m.p. 186 DEG C.) and azodicarbonamide is heated at 200 to 210 DEG C. to give a foam suitable for oil-impregnated bushes or bearings; (2) a piece of aluminium heated to 450 DEG C. is dipped into a mixture of nylon-11 and trihydrazinotriazine. A coating of blown nylon forms on the surface.ALSO:A process for coating metal objects with expanded nylon-11 comprises dipping the heated object into a mixture comprising powdered nylon-11 and powdered blowing agent, the metal having been heated to a temperature at which the blowing agent decomposes and in excess of the melting point of nylon-11.

Abstract: 1409403 Screw-and-nut gearing WERKSEUGMASCHINENFABRIK OERLIKON - BUHRLE AG 6 Feb 1974 [23 Feb 1973] 05415/74 Heading F2Q To prevent deflection of a machine tool lead screw 6 due to axial and torsional movement under load of a slide 4, traversed by a nut 5 on the screw, two rings 9, 10, encircling the screw and nut and bearing on transverse plain surfaces 8, 9 on a circular flange 7 on the nut 5, extend into annular grooves 16, 17 in the slide 4, chambers of which receive supporting hydraulic pressure, and there is sufficient play between the rings 9, 10 and grooves 16, 17 to permit inclination of the rings therein, and hence inclination of the slide 4 relative to the nut 5. The following means is then provided to ensure that, in spite of the movement of the slide 4 relative to the nut 5 under load, rigidity in the required direction of movement of the slide is obtained. Parallel to and axially spaced from the nut flange 7 is a pair of nut projections 18, 19, the upper 18 of which has transverse plain surfaces 20, 21 bearing on part-spherical segments 22, 23, Fig. 2, spherically seated in the slide 4, whilst axial plain surfaces 30, 31 on the upper projection 18 bear on similar segments 32, 33 in the transverse plane, spherically seated in the slide 4, and on the lower projection 19 bear on segments 38, 39 spherically seated in load-pistons 46, 47 in slide chambers 48, 49. Conduits 55, 56 lead hydraulic pressure through restrictors 52, 51 to opposing chambers loading the axial segments 22, 23 and rings 9, 10 as follows. The conduit 55 connects a ring- loading chamber 16 with a similar chamber 26 of the segment 22, whilst conduit 56 similarly connects ring and segment chambers 17, 27. Thus rightward axial load on the nut 5 causes the ring 10 to increase the pressure in chamber 16, which increase is transmitted to chamber 26 to act through the segment 22 on the nutprojection 18, thereby generating a counter force which maintains the adopted relative position between the slide and nut to maintain rigidity of the feed movement whilst still protecting the lead screw 6 from the bending load which would otherwise result if the nut 5 were unable to move in the slide to said position. The conduit 56 acts similarly for leftward axial load. An additional pair of pressure supply conduits 59, 60, Fig. 3, similarly feeds chambers 34, 37 of the transverse segments 30, 31, communicating with opposing load chambers 49, 48 of the support pistons 47, 46 of the transverse lower segments 39, 38, which generate a counter torque opposing any torsional load on the nut and isolate the lead screw 5 from transverse forces which would be caused by such torsional load on the nut due to inclination of the slide 4. The various bearing surfaces on the rings and segments have chambers supplied with pressure fluid to form hydrostatic bearings.

The trip lever is retained in the driving position by a lug engaging a recess 33 in a lever 30 pivoted at 29 to the machine frame, Fig. 3, the other arm 31 of the lever being provided with a brake pad 35 and a feeler rod 42. The feeler rod is fixed to a shaft 41 rotatably mounted in a bearing 37 carried bv the lever and provided with two stops 44, 45 against which the end of the feeler rod engages. The bearing 37 has loosely mounted thereon an eccentric tumbler cam 38 provided with two stop-pins 39, 40. Should the thread break, the feeler rod 42 drops until the end engages the lug 45 on the bearing 37 and the tumbler cam is tilted by the stop 39 against the belt 25; the cam is pressed outwards and moves the lever 31 further to the right so that the jockey pulley 23 is released and the brake pad 35 is applied. An alternative method of actuating the trip lever is by means of a link 46 and stop rod 48 carrying a stop 49, against which the thread on the spool contacts after a predetermined diameter of winding has been reached.

Abstract: 956,293. Hoppers. NIAGARA ENGINEERING CO. Ltd. May 16, 1962 [Feb. 16, 1961], No. 5830/61. Heading B8S. To discharge wet material, which may be of a putty-like consistency, from a fuel or other hopper a vertical wall 5 of the hopper is fitted with a reciprocatory plate 41 and an endless conveyer 20 is mounted to feed material over a base plate 15 which slopes downwardly towards an outlet at the base of the vertical wall 5, discharge being effected by a stepwise operation on the conveyer in synchronizm with the reciprocation of the plate 41. The drive of the latter is from a motor shaft 48 on which are mounted eccentric discs 47 whose rotation raises and lowers a pair of connecting rods 45 which engage brackets 42 secured to the plate 41. The conveyer 20, a scraper conveyer, is driven by a sprocket 17 through the agency of a rocking plate 32, Fig. 1A. This plate carries an abutment 37 which has a lost-motion arc between fixed and adjustable stops 36, 38, carried by a pawl plate 31. Only when abutment 37 contacts stop 38 does the plate 32 cause the pawl 33 of the pawl plate to rotate a ratchet 29 keyed to the shaft 17. A lever 52 pivoted to plate 32 is articulated to a lever 50, Fig. 1, (not shown), connected in turn to one of the connecting rods 45 which drive the plate 41. In this way it is ensured that the conveyer advance is operative during the upward movement of plate 41, the length of each advance being controlled by the setting of stop 38. The size of the hopper outlet is adjustable by bodily movement of the base-plate 15 and conveyer 20, effected by a sprocket and chain 25, 26. In the application of the invention to furnace stoking the hopper is mounted as shown on the inlet of a rotary blade-type mechanical stoker 1.
