Title: Improvements in meat-mincing and sausage-making machines
IPC: B02C18/24
Filed: 1929-09-18
Abstract: 335,056. Wright, F. H., and Lewis, E. W. Sept. 18, 1929. Addition to 260,861. Guards, controlling.-Relates to a number of modifications of the safety devices described in the parent Specification. Firstly, the upturned and rearwardly extending end d<2> of the sliding bolt d is engaged by a stop 6 on a member 5 carried at one end of a shaft 1 journaled in the casing 2. The other end of the shaft 1 carries a cam 3 having a slot 4 which engages a lug a<1> on the cover a, so that when the shaft 1 is locked the cover cannot be raised. The bolt d carries a depending pin d<1> controlling the knife clutch E, and is slid by linkage 0<1> k. which is itself locked as described below. When the bolt d is slid to disengage the clutch E, the upturned end d<2> is moved away from the stop 6, and the cover may be opened. During the opening, the lug a<1> turns the cam 4 and positions the stop 6 as shown in Fig. 4, thus preventing the clutch from being re-engaged whilst the cover is open. The member 5 is retained in position by a spring 8 which bears against stops 6, 7. When the cover is closed, the lug a<1> tilts the member 5, and the sliding of the bolt d positions the stop 6 beneath the end d<2> and prevents the cover from being opened. The linkage ol, k may then be operated to re-engage the clutch E. Secondly, the lever g for actuating the clutches for the chopping- knives and the mincer B is secured to a disc 22 having diametrally opposed grooves g<3>, g<4>. The grooves are engaged by a projection u<5> on one end of a lever u, the other end having a projection u<4> and recess u<3> which co-operate with a groove v<3> and protuberance v<4> on a disc v<2> coaxial with the switch handle v. With this arrangement, when the switch is " on " the projection u<5> is forced into one or other of the grooves g<3>, g<4> according to whether the silent cutter or the mincer is clutched in. Before the clutch lever g can be moved, the switch v must be moved to the " off " position. Thirdly, a mechanical governor associated with the vertical driving shaft displaces a pivot-ed toe-piece which locks the clutch-operating linkage until the speed of the chopper knives has dropped. Fourthly, an independent clutch is fitted in the shaft o driving the bowl of the chopper, the clutch being actuated by the handle 14.

Title: Methods and apparatus for storing flowable solid material
IPC: B65G11/08
Filed: 1928-10-03
Abstract: 322,577. Adams, H. Oct. 3, 1928. Granaries.-A method of handling and mixing broken material, such as coal, of different sizes in a pile or mass in which the larger pieces are substantially segregated from the fines, comprises withdrawing the material from the mass at an outlet below the fines, and limiting the withdrawal of the material to the top layer of the mass and a slowly downwardly moving column over the outlet. The apparatus comprises a receptacle 10, 11, 12 in which is a shoot formed by two sides 18 and the container wall 10, the front 19 of the shoot being open to the receptacle. A hopper 20 is provided at the top of the shoot and staggered baffles 22 are provided in the length of the shoot to prevent breakage of the material. An outlet 41 is provided for the mixed material and an outlet 23 for the large pieces of material. Four angle-irons 25, 26 bound the outlet 41 and heating pipes or electric conductors 40 are housed in the angles to prevent the wet coal &c., from freezing. The coal from the hopper 20 descends along the baffles 22 and is discharged through the open side 19 of the shoot, the fines being deposited near the unclosed side and the large pieces rolling over the pile. The fines in the column 27 are first withdrawn through the outlet 41 and separately disposed of, the corner-pieces 25, 26 limiting the withdrawal to an upright column over the outlet in contact throughout three sides 29 with the main body. This causes the top layer 30 only to be fed to the top of column 28, mixing the large pieces with the fines adjacent to the column as the top layer moves to the column. If larger pieces mostly are required they may be withdrawn through the opening 23. Specification 112.453, [Class 78 (iv), Loading &c.], is referred to.

Abstract: 927,548. Liquid-blast switches. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Aug. 4, 1961 [Aug. 12, 1960], No. 28442/61. Class 38 (5). In a small oil volume circuit-breaker having an intercepting device providing cross-jet and axial-flow arc extinction a plurality of valves are arranged to be operated at different oil pressures so as to provide pressure waves in the intercepting device in dependence upon the arcing conditions. As shown, the circuitbreaker has an intercepter chamber 2 including cross-jet and axial-flow arc extinction elements 5, 6. Valves 12 and 14 are arranged to close at different pressures since the latter is smaller and is spaced by passages 13, 3A at a greater distance from the contacts 3, 4. After the valve 14 is closed, by higher pressure, a valve 15, on which the valve 14 is mounted, is opened by increased pressure against the bias of an adjustable spring 16. The elements 5 are shaped as shown in Fig. 2 so as to shield the oil in areas 5A from arc radiation. The moving contact 4 has a hollow bore 4A including a non-return valve 17 so as to provide an axial stream of oil on low current arc interruption. The moving contact 4 is controlled by an hydraulic ram device 10 having a piston 20 with a conical extension 21 which enters a duct 22 with decreasing clearance to retard the final opening movement. To damp the final closing movement a piston 26 is moved by the piston 20 against the bias of a spring 26A and an oil escape slot 9A in the operating shaft 9 is tapered at its lower end to reduce the oil flow from the space above the pistons 20, 26.

Title: Improvements in or relating to the production of ammonia, potassium carbonate and potassium hydroxide
IPC: C01D1/26
Filed: 1931-10-14
Abstract: Ammonia and potassium carbonate or hydroxide are obtained by treating a mixture of the double salt MgCO3.KHCO34H2O and carbon with nitrogen at a high temperature and hydrolysing the resulting product containing potassium cyanide with steam.  The cyanidization step may be carried out at about 950 DEG  C.  The hydrolysis may take place at 350-500 DEG  C.  If the hydrolysis is carried out with the potassium cyanide heaped up in bulk, potassium carbonate is obtained; but if the steam is passed over thin layers of the cyanide, potassium hydroxide is formed.  Magnesium chloride which is obtained as a by-product in the production of the above double salt may be decomposed into chlorine or hydrochloric acid which may be combined with the ammonia to form ammonium chloride.  The magnesium oxide remaining when the potassium hydroxide or carbonate is separated from the hydrolysed product may be returned for conversion into the double salt.
