Title: Improvements in or relating to apparatus for mincing minceable materials
IPC: B02C18/06
Filed: 1969-05-01
Abstract: 1,237,661. Comminuting-apparatus. A. STEPHAN U. SOHNE. 1 May, 1969 [4 May, 1968], No. 22394/69. Heading B2A. [Also in Division A4] A meat comminuting machine comprises a houseing 2 having an inlet, Fig. 1, a motor driven shaft 3 secured to a rotary cutter 4 within the housing, a first stationary cutter 5 of generally annular section to which is secured a second generally annular cutter (6) Fig. 4 (not shown) cutters 5 and (6) surrounding and being concentric with cutter 4, cutting parts 6a of cutter (6) being interposed between two adjacent cutting ports 5a of cutter 5, and cutter (6) having vertically spaced guide ribs 6b on an inner surface facing cutter 4. The guide ribs 6b are formed by cutting grooves 6c in said inner surface and are said to distribute the meat to be comminuted evenly over the height of cutting parts 5a, 6a and cutting parts 4a of cutter 4. Ends of the guide ribs 6b Fig. 5, on a cutting part 6a are positioned very close to a cutting edge 5b of an adjacent cutting part 5a, the gap between the ribs and edge 5b defining a cutting gap 6d. A rib may be approximately 0.079 inches high, and have its parts spaced 0.197 inches from like parts of an adjacent rib on the same cutting part 6a. The sides of cutting parts 4a are inclined to the vertical, Fig. 2 (not shown) and cutting parts 6a have a generally trapezoidal horizontal cross section. Meat is comminuted between the cutter 4 and cutters 5 and (6) and is then forced through the gaps 6d where further cutting is effected by cutting edges 5b and adjacent ends of ribs 6b.

Title: Improvements in apparatus for cleaning, winnowing, or separating, tobacco
IPC: A24C5/39
Filed: 1919-09-12
Abstract: 140,322. Wood, M. A., (Teale, B. E.). Sept. 12, 1919. Separating by throwing-apparatus.-In apparatus for cleaning, winnowing, or separating tobacco, the tobacco is showered upon a rotary propelling-device 13 which separates the heavier from the lighter parts by causing them to pass along different trajectories. The invention is shown as applied to a cigarette-making machine feed, the tobacco shower being produced by the feed-drum 4 and picker device 8. The lighter portions of tobacco projected from the rotary device 13 fall directly on to a delivery belt 9, or impinge upon a baffle-wall 15 and fall from thence on to the belt, while the particles of stalk and other heavy foreign matter pass over the baffle and into a receptacle 16 which is hinged at 17. Above the receptacle is placed a deflecting-hood 19 to which the receptacle is secured by an ordinary sash-lock or other fastening 18. The rotary device 13 is provided with radial vanes, which are preferably inclined rearwardly, as shown, and may be driven at different speeds by means of a belt and stepped pulley.

Title: Mixing and modulating of liquid fuel and air for internal combustion engines
IPC: F02M19/08
Filed: 1971-04-19
Abstract: 1343311 Spray carburetters DRESSER INDUSTRIES Inc 19 April 1971 [6 March 1970] 22597/71 Heading F1B A carburetter has an axially movable member 33, Fig.3, or 63, Fig. 11, defining an adjustable constriction 35 or 65 in the induction passage 32 or 62 and the flow of fuel from a nozzle 40 upstream of the constriction or from the annular outlet of a space 71 surrounding the induction passage is metered, e.g. by a valve 100. The flow of fuel is substantially independent of the velocity of air flow through the passage 32 or 62 and at most levels of vacuum in an intake manifold supplied by the carburetter sonic velocity occurs at the constriction 35 or 65 due to the gradually increasing flow cross-section downstream of the constriction. The increasing flow cross-section may be equivalent to that provided by a cone with an apex angle from 6 to 8 degrees. Air may be admitted substantially tangentially in to the passage 32 through a pipe 36 and the fuel may be aspirated in to the nozzle 40 by air under pressure e.g. 40 p.s.i, for discharge substantially radially from a baffle 41. The member 63 is connected to the valve 100 for conjoint operation and the connection includes adjustable pivot points to vary the relative movements. The member 63 is moved by rotating the threaded rod 17 in the nut 76 pinned to the member, the rod sprocket 92 being operated by a chain (93), Fig. 13 (not shown), from a sprocket (91), Fig. 12 (not shown), rotated through gearing (83, 85, 89) by a rack (82). To compensate for the force exerted on the mechanism by the vacuum acting on the member 63 a piston (124), Fig. 9 (not shown), subject to the vacuum, acts on the mechanism. The constriction may be defined by converging surfaces of the induction passage and the movable member and the cone angle of the passage surface may be larger or smaller than the cone angle of the member surface.

Abstract: 957,900. Valves. FAIREY ENGINEERING Ltd. June 18, 1962 [June 22, 1961], No. 22708/61. Heading F2V. [Also in Divisions B7, F1 and G3] A pneumatic control system for actuating a control surface or control pressure jet of a rocket propelled guided missile comprises a double acting pneumatic jack 10 having both of its ends adapted to be permanently connected through branch conduits 25A, 25B having throttling restrictions 26A, 26B with a supply of hot compressed gas, each branch conduit having a relief port 21A, 21B communicating with a low-pressure region, and selector valve means 36 having two operative positions and an intermediate position, the valve means in either of its two operative positions fully closing and sealing one relief port and fully opening the other relief port. The relief ports open to the atmosphere in a concave surface 31 of a member 30 secured to a frame supporting the jack. The valve means consists of a member 36 which has a convex surface 37 and is secured to an armature 33 movable from an intermediate position, wherein each port is partly covered, to one or other of the operative positions by selective energization of electromagnets 41, 42 having U-shaped cores on opposite sides of the armature, the coils being energized by signals from the gyroscopic controls of the missile or from a ground control station. When a coil is energized to move the member 36, the complete opening of one relief port causes a drop in the pressure in the chamber of the jack associated with that port and the closing and sealing of the other port causes a rise in pressure in its associated chamber to effect movement of the piston of the jack. In the intermediate position, the cylinder is filled with stagnant gas and when the selector valve is operated to effect movement of the piston, the opening of a relief port permits the hot gases to escape without passing through the cylinder. The double-acting jack may comprise two cylinders having a common piston or their two pistons coupled together and the selector valve may be of the slide or plunger type.

A road or rail vehicle has a vertically movable member 4, actuated by hydraulic rams, to keep the load in place. The rams may be arranged in the hollow corner members 3 and may be interconnected in pairs so that with one ram inverted with respect to the other, fluid displaced from the underside of one piston is transferred to the underside of the other piston to obtain a similar displacement and a parallel movement of the member 4. Fluid to actuate the rams is discharged from a hand or powerdriven pump and a relief valve in the circuit may limit the pressure exerted by the member 4 on the load and the member 4 may be retained in position by valves preventing fluid interchange between the rams.
