Title: Process of producing stuffing box packings and packings manufactured by the process
Inventor: RADKE RUDOLF
Filed: 1958-08-26
Abstract: 832,054. Stuffing-box substitutes. KIND, P., and KIND, A., [trading as FRANKFURTER ASBESTWERKE P. KIND K.G.]. Aug. 26, 1958, No. 27332/58. Class 122 (5). [Also in Group IX] Stuffing - box packings are made by applying a lubricating solid to fibres so that every fibre is as far as possible completely enclosed by it, forming the fibres into threads and then making the packing from the threads. The fibres may be of cotton, wool, silk, artificial silk, polytetrafluoroethylene, asbestos, glass, quartz, mineral wool, slag, and the solid lubricant of graphite, mica or talc, molybdenum bisulphide, lead, copper, tin, aluminium or zinc. A bonding agent is generally used in conjunction with the solid lubricant and may be of natural or synthetic rubber, resins or animal, vegetable, or synthetic glues. The bonding agent may be applied to the fibres before the application of the solid lubricant or it may be applied together with the solid lubricant. The treated fibres may be spun into a yarn and then woven into a fabric from which the packing is made. As shown in Fig. 1, the packing 1 is built up of a number of layers of yarn 2, the direction of the threads 3, 4 of adjacent layers being opposite so as to give greater strength. Alternatively, a long thread may be wound around a reduced end of a shaft until a diameter greater than the adjacent larger portion of the shaft is obtained. The threads may also be plaited or knitted into a tape and then wound around a former. The packing may be treated with chemicals, such as silicones or synthetic oils, in order to increase its resistance to the particular substance being sealed.

Title: Lever mechanism for withdrawing press rods and the like
IPC: A01J21/02
Filed: 1928-09-26
Abstract: 323,052. Ewart, R. D. Sept. 26, 1928. Extrusion machines.-A reciprocatory ram or plunger rod of a press is operated in one direction by engagement of a roller or projection thereon with a bow-shaped lever the fulcrum of which is close to the line of reciprocation, the arrangement being such that, as the, lever applies a tractive force, the roller or projection rides along the lever in a direction away from the fulcrum thereof. The invention is shown applied to a press for extruding butter or like plastic substance, the machine comprising a frame 20 with a shelf supporting an open ended container 23 which stands on an extrusion die 28 and is clamped in position by eccentrics 35 acting on springs 38 when rocked by a lever 37. An upper shelf 24 supported by tie rods 25, carries a plunger rod 26 terminating in a piston 27, together with the operating mechanism, the rod being formed along one edge with ratchet teeth 48 and, at the sides, with longitudinal channels 26<b> which, by engagement with the adjacent ends of the spindles 36, Fig. 3, carrying the eccentrics 35, act, in conjunction with fixed bearing rollers 44, 45<a>, to guide the rod in its movements. The rod is fed in the downward direction through ratchet driving mechanism comprising a gravity or spring controlled pawl 49 on a lever 51 which may be rocked directly or by a cam 54 rotated by a lever 56.. Retrograde action is prevented by a detent 49<a>. The plunger is retracted by means of a bow shaped lever 41 mounted on a pivot 42 adjacent to the line of motion. The roller 40 on the end of the rod, which rides on the lever, is preferably knurled and provided with a handwheel 47 whereby it may be rotated to assist the action of the lever. The roller seats in a recess in the lever to retain the parts in raised position. To release the rod for actuation by the lever, a spring pressed trip lever 58 normally tends to disengage the driving pawl 49 which in turn disengages the detent 49<a> by pressing on the tail thereof. When the lever 41 is lowered, a projection 41<a >thereon presses the trip lever 58 out of action so that the ratchet feed may become effective. The downward feed may alternatively be effected through worm and wheel, rack and pinion gearing or screw &c. mechanism. To facilitate cleaning &c., the piston may be supported in a partly lowered position, after removal of the container, by raising the lever 37 and interlocking it with the lever 41. Specification 319,376 is referred to.

Filed: 1947-10-17
Abstract: 646,295. Optical sound-recording apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 17, 1947, No. 27812. [Class 40 (ii)] [Also in Groups XX and XL (b)] In a device for producing a variable width sound film record, a film is scanned by the trace of a C.R.T., the scan width varying with the sound amplitude. As shown, the sound is amplified at 11 and a push-pull voltage produced at 12 proportional to the sound amplitude. The control grids of valves 13, 14 are energized simultaneously from 12 and the sawtooth generator 7, and the interval between the negative impulses generated at resistors 25, 26 depends upon the voltage amplitude at' 12. Normally, the valve 27 conducts and 28, 46 are shut down, and on receipt of the negative pulse from 25, which occurs before that from 26, the valves 27 and 28 cease and commence to conduct respectively. A negative pulse is therefore applied from 33 to the modulating element of the C.R.T. 1. The subsequent negative pulse at 26 arrests the conduction of 28 and causes valve 46 to conduct. The pulses generated at 32, 33 are complementary and either may be applied to 9 to enable either positive or negative film to be used. If the area of the exposed film is to vary in accordance with the beam amplitude of the sound, the push-pull rectifier 57 in conjunction with a circuit having a time constant which is long compared with the lowest frequency of the sound signals, is employed.
