Title: Improvements in or relating to methods of making batches of uniform coffee infusions
IPC: A47J31/00
Filed: 1966-06-07
Abstract: 1,146,500. Uniform coffee infusions. CORNELIUS CO. 7 June, 1966 [17 Sept., 1965], No. 25406/66. Heading A4D. Batches of uniform coffee infusions are made in a system comprising a pressurizable chamber 12 of predetermined size which is substantially filled with dry ground coffee from a funnel 13 through a valve plate 14 controlled by a motor 15. A valve plate 17 under the control of a motor 18 closes the lower end of the chamber 12. Water is discharged from a waterheater 19, provided with a heater 20, through a constant pressure regulator valve 22 under the control of a solenoid valve 23 to the inlet 24 of the chamber 12 to form an infusion which passes through an outlet 26, a check valve 27, a solenoidoperated 3-way valve 28 and into a storage tank 29. The time for which water is allowed to flow through the chamber is predetermined and closely regulated. The infusion in the storage tank 29 may be diluted with water or with carbonated water if it is to be kept, a source of pressurized carbonated water 30 being connected via the 3-way valve 28 to the tank 29, which may be purged previously with CO 2 . The extraction may be interrupted, thus the pressure at the inlet 24 may be relieved momentarily to correct any channelling of the coffee bed. Used coffee grounds are flushed out of the chamber by water from a source 42, through a waste pipe 43a. The process may be carried out automatically by an electrical control system ((Fig. 2, not shown).

Abstract: 601,334. Copying documents. BLOCK & ANDERSON, Ltd., and GERLACH, H. Oct. 1,1945, No. 25476. [Class 100(ii)] In a rotary mirror script duplicating-machine control means, operable by a single manual operation are provided for simultaneously rendering inoperative the means for moving the damping apparatus out of operative position and the means for holding the cylinder in the copy sheet receiving position, so that the machine can be run continuously to print webs or long sheets. The damping pad 14, Fig. 1 is moved into and out of operative relation with the sheets passing over the plate 13 by means of an arm 19 comprising two parts 28, 29 hinged together by a pin 30, the outer part 28, carrying a roller 25 which may be engaged by a rise 27 on a cam disc 26 fixed to the spindle of the printing cylinder 10. A lever 32 has a projection 34 which, in the position shown in Fig. 1 engages the part of the cam disc 26, so that at the end of each revolution of the cylinder 10, the pad 14 is moved away from the plates 13 against the action of a spring 21. When the lever 32 is moved to the right of Fig. 1 into the position shown in Fig. 5, spring 31 arranged between lugs on the parts 28, 29 of the arm 19 moves the roller 25 clear of the disc 26 so that the pad 14 remains in operative position and the damping is continuous. The lever 32 is formed with a sleeve 47 pivoted on a hollow trunnion 33, housing a spring-pressed plunger 43 adapted to engage a recess 45 in the cam disc 26 to hold the cylinder in the sheet-receiving position. The plunger has a projecting pin 46 engaging a cam slot in the sleeve 47 so arranged that when the lever 32 is moved into the position of continuous damping the plunger 43 is retracted into the position A spring-held lever 37 pivoted on a bracket 23 has two recesses to receive a roller 42 on the lever 32 to hold it in one of its two positions; alternatively, the lever 37 may have two rollers which engage a recess in lever 32.

Title: Improved apparatus for the hot drawing of steel and other hard, ductile metals or alloys
IPC: B21C1/02
Filed: 1950-10-20
Abstract: 696,298. Automatic control systems. MARSHALL RICHARDS MACHINE CO., Ltd., and SOMERVILLE, T. B. Oct. 17, 1951 [Oct. 20, 1950], No. 25592/50. Class 38 (iv). [Also in Groups XXII and XXXVII] Apparatus for hot drawing wires, rods, tubes, angles, &c. comprises a drawing block and die, and heating means through which the metal passes immediately prior to its entry into the die, a substantially constant torque being applied to the block, whereby the speed of the metal through the heating means is varied automatically to maintain substantially constant the temperature at entry of the metal into the die. If the temperature of entry falls the pull required to draw increases and since the pull of the machine is constant, the speed of drawing is automatically reduced allowing the material to remain under the influence of the heating means for a longer period and its temperature to rise. If the temperature rises too high, the speed of draw is increased and the material passes through the heating zone more quickly. Wire 1, passing through a hot lead bath 2 and resistance heated by means of a transformer 4, is drawn through a die 3 by a separately excited constant torque motor 7. A manually adjustable rheostat 12 allows the torque to be adjusted, and the armature 13 is supplied from a grid controlled rectifier 14, with a current regulator 22 and phase shifter 17 in the circuit. In a modification a shunt field winding causes the torque at high speed to decrease, when a higher torque at starting and slow running is necessary. The drawing block may be driven through an electro magnetic slip coupling or an A.C. motor with an induction regulator.

Abstract: 506,981. Refrigerating; cooling air. JERRARD, E. P., and JERRARD, P. H. Sept. 1, 1938, No. 25645. Addition to 489,539. [Class 29] The oscillating column of liquid produced by the expansion of compressed air in tubes 2 in the manner set forth in the parent Specification serves to raise liquid by a hydraulic ram action. The liquid column oscillates through a horizontal conduit 3 connected to a pipe 4 rising to an elevated tank H, which is connected to a " supply " tank S through a pipe 12 with control valve 16. An air chamber 18 is connected to the pipe 4 above a loaded valve 15, and a return pipe 11 from the tank S is provided with a valve 14 opening downwardly by its own weight. The momentum of the water column when air expands in the tubes 2 closes valve 14 and opens valve 15, and lifts some of the water to the tank H. On the return stroke the water flows out of tank S through valve 14. The water from tank H may drive a Pelton wheel 7, which may be coupled to an electric generator 10 and to an air circulating fan 8, as described in the parent Specification. The heat-interchanging tubular member may be located in the tank S, the air to be cooled being circulated outside the tank.

Abstract: 786,160. Mixing. SMIDTH & CO., AKTIESELSKAB, F. L. Sept. 7, 1955, No. 25646/55. Class 86  In a method of forming a homogeneous slurry in a circular basin having one or more frameworks rotating about the central vertical axis of the basin, each framework carries means for supplying slurry and compressed air to the basin and means for scraping the bottom of the basin, and the slurry and compressed air are both supplied substantially evenly over the whole area of the bottom of the basin. As shown, a lattice framework 5 rotatable horizontally about a pivot 4 secured to the top of a central vertical pillar 3 in a circular basin, is supported at its outer end on wheels 6 running on the edge 7 of the wall 2 of the basin. The framework has a tank 8 supplied, with slurry from a pipe 9, the tank being connected to a trough 10 provided with three evenlyspaced pipes 11 through which the slurry is conveyed to the basin. At the junction between the trough 10 and each pipe 11 is mounted a removable circular plate with a hole or holes therein the size of the holes determining the amount of slurry passing into each plate. By varying the diameter of each hole the slurry may be fed substantially evenly over the whole area of the basin. The framework 5 also supports pipes 15 ... 19 connected through a distributing valve mechanism 23 to a pipe 22 supplied with compressed air through a flexible pipe 20. Between each pipe 15 ... 19 and the pipe 22 is an opening provided with a valve 32, Fig. 5 which is opened by means of a rotating cam and a rocker arm 34. The cams may have one, two or more lobes thereon, so determining how many times the "valves are opened during each revolution of the cam shaft 30. Any loose particles which separate out during operation of the machine are scraped to an opening 36 by scrapers 35. These scrapers are pivotally mounted so that they can ride over an obstacle.
