Filed: 1917-12-29
Abstract: 130,032. Leeming, J. A., and Henderson, W. A. C. Dec. 29, 1917. Coupling.-Relates to joining-devices, particularly for joining the broken ends of carrier ropes of aerial ropeways, of the kind formed so that the wheels of a carrier or trolly may pass over, and having curved passages through which the rope ends are passed, stops on the rope ends preventing the pulling-through of the ropes when under tension. The device comprises two plate-like members 1, 1<a> provided with grooves which, when the plates are screwed together, constitute curved passages extending from the front and rear ends of the device to the lower edge thereof, as shown dotted in Fig. 1. The rope ends to be joined are laid in these passages and are either knotted, provided with stops, or gripped together by a U-bolt clamp 11 to prevent withdrawal. Two such devices each provided with a lug 5 may be applied, one to the forward rope and the other to the return rope, the lugs being connected across by a bolt 7. This arrangement prevents the joining- device from twisting. A straight passage 9 may be provided to accommodate the unbroken rope.

Abstract: 1321173 Cooling machine tools METAL CHEMICALS Inc 8 June 1971 [16 June 1970] 19314/71 Heading F4U [Also in Divisions B3 and C5] A method of cooling and lubricating at least one machine tool having at least one cutting tool, at least one spindle and at least one slide, comprises the steps of (a) feeding to such spindle and to such slide a fluid lubricant that is a water emulsifiable composition consisting of a mineral oil together with an emulsifying agent capable of causing the mineral oil to form a stable emulsion with water, (b) feeding to such cutting tool an aqueous emulsion consisting of water, a mineral oil and an emulsifying agent that maintains the emulsion stable, (c) mingling the return flows of the fluid lubricant and the aqueous emulsion, (d) collecting the co-mingled fluids, (e) removing solids from the co-mingled fluids to regenerate an aqueous emulsion, (f) adjusting the composition of the regenerated aqueous emulsion by adding ingredients thereto to bring the regenerated aqueous emulsion to substantially the same composition as the aqueous emulsion initially fed to the cutting tool, and (g) recirculating the regenerated aqueous emulsion to the cutting tool. The lubricating fluid, cutting fluid, and a pressure hydraulic system fluid, may all be based on a mineral oil/water/emulsifying agent mixture with only the water content being different for the different use. De-ionized water is added after a solids separation stage to bring the collected fluid to its original composition. The method is applied to a plurality of machine tools, e.g. drilling, boring, milling, honing or grinding machine tools, having gravity feeds 9, 18 for lubricating and hydraulic fluids, and a pump 18 to circulate the cutting fluid. Compositions of lubricant.-A number of examples of fluids are described containing sodium petroleum sulphonate, oleic acid, aqueous potassium or sodium hydroxide solution, diethylene glycol, butyl carbitol, aqueous rosin cil solution, phenol, tall oil, isopropyl alcohol, phosphoric acid solution, and Midcontinent Pale No. 100 mineral oil. The fluids of the examples are diluted with water to a required viscosity. The emulsifying agents are anionic or non-ionic surfactants, the preferred non-ionic surfactant being condensation products of ethylene oxide with derivatives of fatty acids such as alcohols, amides or amines. The lubricant includes a corrosion inhibitor such as organic phosphates, organic phosphonates and organic phosphites. An alkaline buffer, e.g. ethanolamine, diethanolamine or triethanolamine, is included to prevent acidity. To give extreme pressure properties chlorinated paraffin, sulphorized olefin, or phosphorus compound may be added. An antifoam agent, e.g. silicone, may lie added.

Title: Improvements relating to continuous flow systems and methods of controlling them
Inventor: ASH MICHAEL EDWARD
IPC: C12C11/00
Filed: 1961-05-30
Abstract: <PICT:0999256/C6-C7/1> In a chemostatic process for the continuous fermentation of sedimentable micro-organism in a substrate of lower specific gravity, e.g. brewers' wort, involving continuous equilibrium volumetric flow of substrate through one or a series of vessels containing micro-organisms, the concentration of micro-organisms in the effluent is controlled to have a lower value than the concentration in the main body of substrate.  Wort seeded with yeast enters a pre-fermenter vessel 11, provided with stirrer 17, through pipe 12 and aerater 13 and after the yeast has multiplied in temperature controlled aerobic conditions is drawn off through pipe 14 which communicates with fermentation vessel 18 which has a stirrer 21 and a vent and filter system 19, 20.  Primary effluent pipe 22 connects with an inclined shielding pipe 24 which isolates a region of the liquid in the vessel from the effects of agitation. Secondary effluent pipe 23, and primary effluent pipe 22 have valves 26, 25 respectively which control the rate of flow from the effluent pipes.  Effluent drawn from pipe 22 contains little or no yeast since the yeast tends to settle in the inclined shielding pipe 24.  The effluent drawn from pipe 23 carries yeast at the concentration obtaining in the main body of the vessel. Thus by varying the amount of effluent drawn from each pipe the concentration of yeast in the aggregate effluent may be controlled.
