Title: Improvements in and relating to meat choppers
IPC: B02C18/36
Filed: 1925-08-26
Abstract: 257,407. Johnson, C. E. Aug. 26, 1925. Mincing.-In a mincing machine having two or more perforated face plates which co-operate with rotary cutters, the cutting edges of the cutters are in the form of logarithmic spirals with their origins in the centre of rotation. The angle between the tangent to the cutting-edge at any point therein and the tangent to the circle swept out by the point is less than 46‹ and is the same for all points. The cutting angle of the cutters, i.e., the angle of the cutting-edge in cross section, is less than 46‹. When two discs and two cutters are employed, the back of the innermost cutter is wedge-shaped and impels the material towards the outermost cutter by a screw-like action. The perforations in each disc are arranged not to be numerically the same as the arms on the cutter, or a multiple thereof, in order to prevent simultaneous cutting at all the cutting-edges. As shown in Fig. 1, the two cutters 1, 2 rotate with their convex edges leading. In a modification, this arrangement is reversed. The face plates are held in the mincer barrel by radially projecting lugs which engage longitudinal slots in the barrel walls. Figs. 3 and 4 show sections of two forms of cutting-edges.

Title: Process and apparatus for tapping liquid slag from pressure gas producers
IPC: C10J3/08
Filed: 1949-08-23
Abstract: 669,871. Discharging slag. METALLGES. AKT.-GES. Aug. 23, 1949 [Dec. 31, 1948], No. 21938/49. Class 51 (i). Apparatus for the removal of liquid slag from a pressure gas producer comprises a water-cooled slag notch discharging directly into a casing defining a chamber having a closable discharge opening in line with the slag notch and means for supplying gaseous fluids or liquid to said chamber. In the embodiment shown in Fig. 1 the water-cooled slag notch 2 discharges into the base of a chamber 6 having an opening 7 closed by a plug 5 actuated by a system of levers 15, said chamber 6 being supplied with steam, air, or carbon dioxide through a pipe 8 under control of the valves 16 and 17 arranged in parallel and operated so that a steady minimum supply passes through one valve and a variable supply through the other. When the plug 5 is opened molten slag passes from the producer through a grille 14 and a passage 13 under control of the gaseous fluid supplied through the valves 16 and 17. Flow of slag is stopped by increasing the pressure of the gaseous fluid and closing the plug 5, when the slag recedes into the producer and the gaseous fluid is supplied thereto as additional blast. In a modification adapted for the continuous flow of slag, Fig. 2, the slag passes through the watercooled slag notch 22 into a chamber 26 supplied with water from a tank 39 subject to the pressure in the upper part of the producer transmitted by the pipe 40 and provided with a float 38 controlling a water supply valve 50, and mixed granulated slag and water leaves the chamber 26 by a restricted outlet 34 leading to a waste pipe 37. The rate of flow of the slag is controlled by varying the position of the float 38 and consequently, the pressure on the slag notch 22. If it is desired to interrupt the flow of slag, steam or other gaseous fluid may be supplied through the pipe 35 and the pipe 34 may be closed by a plug. In a further modification of the continuous discharge apparatus, Fig. 4 (not shown), steam &c. may be supplied direct to the slag notch 22, thus avoiding any chance of water entering the gas producer.

Filed: 1958-07-09
Abstract: 877,032. Respiratory masks. AIRMED Ltd. Oct. 9, 1959 [July 9, 1958], No. 21976/58. Class 81 (2). In a modification of the respiratory mask described in Specification 779,943, the toggle which at each side connects the face piece to a support on the wearer's head comprises a link extending forwards from the head support which is laterally flexible. As shown, Fig. 1, each toggle comprises a link 7 pivoted to the face piece 1 at 5 and a link 10, 11 pivoted to a plate 15 on an earpiece 16 mounted on a head band 25, the portion 11 being a chain or other laterally flexible member such as a nylon cord. The links 7 and 10 form the arms of U-shaped members the bases of which pass through a lever 9. In one position of use, Fig. 1, the toggle is locked against downward movement of the links by the abutment of the arms 7 against a rigid member 4 on the face-piece 1 and by the engagement of the chains 11 with hooks 8 projecting from the arms 7. To increase the pressure of the mask against the face the lever 9 is rotated in the direction A, Fig. 1, to an extent limited by a stop (not shown) mounted on the arms 7. This forces the arms 7 between the arms 10 thus increasing the tension on the links 10, 11 and the compression on the arms 7. To remove the mask, the wearer pushes the lever 9 bodily upwards so as to break the toggle, Fig. 2. Microphone and earphone leads 29 are connected to one earpiece 16 and a lead 30 runs from there to a plug (not shown) which may be connected to a microphone 3 in the face-piece or to a microphone capsule 22. The mask may be attached to a helmet in the same way as to a head band by means of attachment plates similar to the plates 15.
