Title: An improved mixing machine for concrete and other materials
IPC: B28C5/18
Filed: 1945-09-14
Abstract: 599,325. Mixing-machines. MAILOFF, L. Sept. 14, 1945, No. 23791. Convention date, May 17, 1944. [Class 86] A machine for mixing concrete and other materials includes three drums movable into filling, mixing and emptying positions successively, and driven in rotation about their respective axes at least during the period for which they occupy the mixing position, so that there may be always at least one drum performing the mixing. Rotary drums 1, 2, 3, Fig. 1, shown in positions for filling, mixing and discharging, respectively, are mounted on shafts 4, 5, 6, respectively, journalled on a rotatable shaft 7 supported in bearings 8 on a frame 9. The drums are rotated by a motor 14 which drives through a chain 15 a bevel gear 13 in mesh with bevel gears 10, 11, 12 on the drums. A charging skip 20 is raised by a cable 18 wound on a winch 17 driven by a chain 16 and a toothed wheel rigid with that driving the bevel gear 13. The chain 16 co-operates with a bevelled toothed wheel 30, Fig. 4, in mesh with two opposed bevel pinions 31, 32 mounted loose on the driving shaft 33 of the winch 17. A control lever 21 operates a clutch member 34 to couple either pinion 31 or pinion 32 to the shaft 33 to reverse the direction of rotation of the winch 17. When the lever 21 is in the position shown, the skip 20 is raised by the winch 17, and a screw-thread 35 on the shaft 33 drives to the left a sleeve 36 carrying prongs 37a, 37b and a finger 44. The latter operates through levers 45, 46, rods 47, 48 and bellcrank levers 49, 50 to retract a spring-pressed rod 51 from one of three notches 53a in a cam 53 fixed on the shaft 7 to permit the latter to rotate. After a short time, the finger 44 moves out of contact with the lever 45, and the rod 51 bears against the cam 53 to engage the next notch 53a and to stop the rotation of the shaft when the drum 2 has moved into the filling position, the drum 1 into the mixing position and the drum 3 into the charging position. Immediately after this change of position occurs the prong 37a carried by the sleeve 36 operates through a lever 38, rod 39 and levers 40, 41, to open a cock 43 and close a cock 42, to empty the water supply tank 22 into the drum 2. When the skip 20 has been fully raised and discharged, the lever 21 may be moved manually or automatically into its opposite position to lower the skip and the carriage 36 moves to the right so that the prong 37b operates the lever 38 to close the cook 43 and open the cock 42 through which the tank 22 is replenished.

Title: Improvements relating to servo systems
Inventor: FUELL FREDERICK JAMES
IPC: F15B18/00
Filed: 1960-07-08
Abstract: 983,740. Hydraulic apparatus. FAIREY ENGINEERING Ltd. July 5, 1961 [July 8, 1960], No. 23996/60. Heading F1P. [Also in Division B7]  A duplicated hydraulic servo system for an aircraft comprises a single-member 20 actuating two servo valves 12, 13 respectively, controlling two servomotors 14, 15 and for each valve a device responsive to the force applied to the valve and serving when the force exceeds a predetermined value to render the connection between the actuating member and valve inoperative. The actuating member 20 is connected to floating levers 24 which are connected at intermediate points to links 25 controlling the servo valves and at their lower ends to pivots 26 on the upper ends of T-shaped cranks 27. The heads of the cranks have adjustable tappets 31 arranged to engage surfaces 32 on cut-out valves 30 having poppets 29 connected to pivots 28 on the cranks. The cut-out valves are normally maintained closed by the pressure from the sources 10, 11 acting on the upper surfaces of the poppets but in the event of a servo valve sticking, the movement of the actuating member 20, when the force applied to the sticking valve reaches a predetermined value, causes the lever 24 of the sticking valve to rock about its link 25 and tilt the associated crank 27 about one or other of the tappets to raise the poppet 30 from its seating so that the respective source 10 or 11 is connected by a line 38 to one end of an associated change-over valve 40 to move its spool 41 against a spring 42. The movement of the spool disconnects the source 10 or 11 from the servo valve 12 or 13 and interconnects ports 53, 54 leading from opposite ends of the associated motor whereby operation of the other motor by its servo valve is not interrupted. The return lines may be connected to chambers 37 in the cut-out valves 30 so that in the event of a return line blocking, the increase in pressure acts in chamber 37 to raise the poppet and render the associated servo valve and motor inoperative. Ball valves 49 in the spools 41 permit leakage past the cut-out valves to pass to exhaust passages 43 in the spools 41 but when the pressure in lines 38 rise as a result of the valves 30 opening, the balls engage seatings 58 to move the spools.

Abstract: 518,170. Moulding by dipping ; cores. BRATRING, K., and INTERNATIONAL, CONTAINERS, Ltd. Aug. 16, 1938, No. 24107. [Class 87 (ii)] Cores for the manufacture of hollow bodies of undercut form by dipping are formed by filling with heated fusible substance under pressure a seamless container, such as a rubber bag 21, situated within a multi-part mould 15, allowing the fusible substance to solidify and removing the filled container from the mould so as to. form the core. The fusible substance is such as to fuse and solidify between 12 and 85‹C. and may be gelatine, jellies, paraffin or other wax, a mixture of magnesium chloride and nitrate, or sodium potassium tartrate or ammonium sodium phosphate. For filling, the rubber bags 21 are suspended in apertures in a support 11 mounted in slots 10 in a guide frame 1. The bags 21 are secured to the support 11 by flanges 22 having conical portions 22a to each of which is welded a perforated tube 24 disposed within a bag 21. The core moulds 15 are mounted on an elastic layer 16 on a base 14. The frame 1 carries a supply pipe 2 for fusible material and having branch pipes leading to the apertures in the support 11 and fitted with ball valves 7. The pipe 2 is provided with a heated jacket 8. In use, the moulds 15, support 11 and pipes 4 are brought into contact by means of eccentrics 17 which move the frame on guides relatively to the base. On contact between flanges on the tube 24 and pipe 4 a valve needle mounted in the tube 24 engages the ball 7 to open the valve and allow fusible material to flow into the bag 21 and expand it within the mould 15. Air escapes through vents 30, 31. When the bags are filled, the supply is cut off and the cores allowed to solidify. The eccentrics are operated to release the parts 4, 11, 15 and the mould parts are moved apart. Composite moulds may be formed by individual mould parts of cast iron or aluminium united by webs. There may be rows of composite parts secured by screws, or a number of rows with a multiple-row filling device.
