Title: Improved gearing mechanism
IPC: F16H35/02
Filed: 1924-01-19
Abstract: 233,754. British Thomson-Houston Co., Ltd., and Tuppen, E. B. Jan. 19, 1924. Toothed, belt, and chain gearing.-Relates to gearing for producing a cyclic variation of speed so that the driven member periodically slows, stops, or reverses, particularly applicable to electric switch gear and controller gear in which it is desired that a switch arm or the like shall pause momentarily on each contact. In the form shown in Fig. 2, the driven wheel 2 turns on a fixed pivot 1, about which swings a frame 8 carrying a driving-wheel 3 gearing with the wheel 2. A crank-pin 5 on the wheel 3 is connected by a link 6 to a fixed point 7 and the wheel 3 is rotated at constant speed bv a universally jointed shaft. The wheel 2 is constrained by the links 6, 8 to swing about the pivot 1 and, when the pin 5 is arranged upon the pitch circle of the wheel 3, the wheel 2 is driven at a varying speed falling intermittently to zero. If the pin 5 is arranged respectively within or without the pitch circle of the wheel 3, the velocity of the wheel 2 either does not fall to zero or is temporarily reversed during each cycle. Other means may constrain the wheel 3 to swing about the pivot 1 and the pin 5 to move radially to the wheel 2. The toothed gearing may be replaced by chain or belt gearing. As shown in Fig. 6, the wheel 3 may be driven by a concentric wheel 14 secured thereto and gearing with a driving-wheel 15 loose on the pivot 1. This drive produces a fluctuation in the speed of the wheel 3, which is, however, small when the wheel 14 is large, and by suitably arranging the pin 5 with relation to the pitch circle, of the wheel 3, the effect of the fluctuation may be overcome and the desired motion obtained.

Title: Improvements in or relating to granular material conditioning method and apparatus
IPC: B22C5/08
Filed: 1962-01-16
Abstract: 965,182. Photo-electric controls; testing caking; weighing apparatus. HARRY W. DIETERT CO. Jan. 16, 1962 [Jan. 16, 1961], No. 1618/62. Headings G1A, G1S and G1W. [Also in Divisions B1, B2 and B3] A method of conditioning granular material such as foundry sand, mortars, ceramics and welding rod flux material comprises continuously mulling the material during addition of an ingredient which affects its mouldability, measuring the varying mouldability of the material during continued mulling and addition of the ingredient, and terminating the addition of the ingredient when the mouldability of the granular material reaches the required value. Foundry sand is mulled in a muller 10 to which water may be added from a main 24 having a large valve 26 and a small valve 28. An outlet 30 from the muller allows samples to be supplied to a separator 35 comprising a vibratory riddle 36 above a tray 38. The riddle is formed of or coated with polytetrafluoroethylene to prevent sticking of the grains thereto. A comparison of the quantity which falls through the riddle on to the tray 38 with the quantity which remains on the riddle gives an indication of the mouldability of the sand. The respective quantities fall on to inclined slides 56, 58, which are pivotally mounted at 60. A greater amount falling through the screen on to the tray 38 and hence on to the slide 56, indicating a higher degree of mouldability causes the slides to tilt anticlockwise, causing an electronic control circuit to open the large valve 26 to supply water to the muller. As mouldability decreases a higher proportion of sand stays on the screen and is delivered to the slide 58, causing the slides to tilt clockwise. A first result due to a snap-over switch 96 closes the valve 26 and opens the smaller valve 28 to cause a reduced flow of water to the muller and then as the desired mouldability is reached an opaque member 90 is interposed between a light source 89 and a receiver 83 to stop the flow of water completely. The addition of additives other than water may be controlled. The operation of the slides may be adjusted to give a predetermined mouldability by variation of a weight. In a modification the movement of the slide regulates through an electro-pneumatic transducer a water-proportioning valve.

Title: Improvements in and relating to the recovery of fat from animal fat-containing products
Inventor: CHAYEN ISRAEL HARRIS
IPC: C11B1/02
Filed: 1949-08-05
Abstract: Soft fat products, e.g. suet, gut-fat or fat-containing meat, are continuously fed with a liquid to a container and are subjected to repeated intense impacts delivered through the medium of the liquid, thereby rupturing the membranes of the fat-containing cells and liberating the fat without any or substantially any of the soft-fat products being reduced to cell size or less, the resulting mixture being continuously removed from the container and the fat removed therefrom by gravity separation or centrifugation without any intervening heat-rendering treatment.  The liquid used is preferably water, and it may be used cold.  The time of treatment is of the order of a <PICT:0722311/III/1> <PICT:0722311/III/2> few seconds, so that hot water may be used provided that the liberated fat is not melted.  The soft fat products may be fed into a rotating hammer mill of the swing beater type in the presence of at least three times their weight of water.  The contents of the mill may be discharged into a separating vessel, preferably containing cold water, the residues falling to the bottom and the separated fat being continuously or intermittently removed from the surface.  As shown (Fig. 1), the soft fat products are fed continuously into a hammer mill 2 fitted at its outlet 4 with 0.25 inch grids.  Water is fed into the mill through pipe 3.  The contents of the mill are discharged into a separating vessel 5 containing cold water.  Any solid residues fall to the bottom, where they accumulate and may be removed by outlet 7 or continuously removed by an inclined worm 10 (Fig. 3).  The fat, which separates on the surface as a foam, flows over the weir 8, water being removed from the vessel by the siphon pipe 9; this water may be returned to the mill or drained away.  Fig. 3 shows an arrangement whereby water is pumped by pump 11 from the separating vessel and recirculated through the mill.  One or more vertical baffles 14 with a clearance space 15 at the bottom is provided in the vessel 5, the mill discharging into one of the compartments so formed and the pump drawing water from the other. The separated fat may be heated to 94-98 DEG  C. and allowed to settle to form a clear layer on the water.  Traces of fat may be removed from the water layer if desired.  The solid residue from the separating vessel may be recirculated through the mill, dropped into and/or agitated with hot water, and may be allowed to settle or centrifuged, either as obtained or whilst being sprayed with steam or hot water.
