Abstract: 167,246. Gilson & Co., Ltd., and Wright, A. F. J. April 30, 1920. Lathes; turning wood-screws; screwing.-In an automatic machine for turning screws, the work is stationary and the turning and parting tools and die rotate. The various operations are controlled by a cam shaft 25, which makes one revolution for each complete cycle of operations. The shaft 25 is driven from a pulley 26 through worm gearing 27. The stock 8, which may be wire from a reel, or a. straight rod, is fed forward intermittently by a head 5, having jaws 81, 82, which are drawn together by a cam 83 acting between the jaw 82 and a block 84 connected to the jaw 81 by side plates. The cam 83 is carried by a spindle 93, an arm 89 on which is operated by a cam 32. The head 5 slides on rods 6 under the action of a cam 36, and is retracted by a spring 38. During the rearward movement of the head 5, the stock is held by a pin 48, operated by a cam 42 through a lever 44. The turning and parting tools 11, 12, which may be in the form of notched discs, as shown in Fig. 11, are carried by a cage 10, which is supported at the left by a bush 101 carried by a standard 2, and is formed integral with a sleeve 104, carrying a driving-pulley 16, and supported in bearings in standards 3, 4. The tools 11, 12 are mounted on spindles 121, 122, carrying arms 123, which engage cam-slots in a sleeve 15. The latter is moved axially, to bring the tools alternately into operation, by a lever 52 operated by a cam 50. The threading-tool 13 is mounted in bushes in the sleeve 104, and carrying an arm 113 engaging a trigger 112 in a drum 21, which is rotated alternately in opposite directions for threading and withdrawing the die. For this purpose the drum is formed integral with a sleeve, mounted on the sleeve 104, and carrying a fixed pulley 19, on each side of which are loose pulleys 17, 18 for open and crossed belts respectively. The belts are shifted by forks carried by a lever 64, pivoted at 65, and carrying a bowl 63, which is struck by wipers 62 on a cam 59. The end of the lever 64 engages notches in a lever 69, acted on by a. spring. In order to engage the die with the work, the spindle 14 is pressed axially by a lever 23, a bowl on which is struck by a projection 73 on a cam 72. The trigger 112 has a bevelled end, and, at the end of the threading operation, the arm 113 presses the trigger back against the action of a spring. Lubricant is supplied to the hollow spindle 14 by a box 115, rotation of which is prevented by levers 116, 117. In a modification, the spindle 14, and a sleeve carrying the tools 11 and 12 are separately supported in the standards 3 and 2 respectively. A transferrer may take the parted work, for example, to a saw for cutting nicks in the heads of the screws.

Title: Method and apparatus for continuous centrifugal decantation
IPC: B04B1/00
Filed: 1946-04-18
Abstract: 610,995. Centrifugal separators. COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTRO-METALLURGIQUES ALAIS, FROGES. ET CAMARQUE. April 18, 1946, Nos. 12029, 12030 and 12031. Convention dates. April 19, 1945, Feb. 21, 1946, and Feb. 27, 1946. [Class 23] Separated solids are removed continuously from a centrifugal separator by means of a carrier liquid which is conveyed to the solids in a radially outward direction and, with the entrained solids moves inward to the discharge. The carrier liquid may be supplied under pressure to the separator by a pump. In a separator of the type shown in Fig. 4, the mixture to be treated is admitted at 6 and the clarified liquid is discharged into a trough 20. The carrier liquid is admitted at 14 passes by pipes 15 to the periphery and carries the entrained solids inwardly through the pipes 5 to a discharge trough 22. The depths of the liquids in the troughs 20, 22 is varied by adjusting the extraction pipes 21, 23. In a separator of the type having a number of cone pieces 2, Fig. 7, the mixture enters by a passage 8 and a perforated partition 10 and the clarified liquid is discharged through a passage 12. The carrier liquid is introduced between the cone's 2, 3 and, entraining the solids at the apex of the cones, carries them inwards through the tube 4 to the discharge passage 5. The passages 5, 12 may lead to discharge troughs or to calibrated orifices. To prevent the movement of the carrier liquid causing a disturbance of the body of liquid in the cone, a flared pipe 38 gathers any inwardlymoving liquid and conveys it to the entry chamber 9. In the form shown in Fig. 10, the separated solids pass into a channel 25. the carrier liquid is spread into a conical sheet by a device 26 and carries the entrained solids into an annular space 27 which leads to the discharge pipe 4. In the form shown in Fig. 8, separated solids reach the cavity 31, the carrier liquid is introduced by the channel 29 and the entrained solids are carried away by the pipe 4. The flow of the materials is regulated by means of a plate 33a. A washing fluid can be introduced through a port 35. The apparatus is described in connection with the separation of the red muds in suspension in solutions of aluminate of soda derived from the treatment of bauxite by the Bayer process. The carrier liquid may be a weak solution of aluminate of soda and may be, later, separated from the red muds for repeated use. The weak liquor may be emulsified in the centrifuge with a gas or vapour. The larger particles of red mud may be separated out by other apparatus before the suspension is introduced to the separator.

Abstract: 1,009,628. Delivering measured quantities of liquid. MASSEY'S BURNLEY BREWERY Ltd. March 26, 1964 [March 28, 1963], No. 12251/63. Heading B8N. An apparatus for dispensing measured quantities of liquid, such as beer, including a measuring chamber 10 into which the liquid flows before being dispensed, the interior of the measuring chamber being maintained under constant gas pressure which is high enough to prevent egress of gas from the liquid, but low enough to permit the liquid to flow into the chamber, the gas to produce the said pressure being introduced from a gas gallery 12. The measuring chamber is in the form of a glass cylinder 14 clamped between a base 16 and a cap 18 by means of rods 15; the base and cap may be of glass, metal or plastics material. The interior of the measuring chamber is connected, via a port 34 in the cap and a pipe 36, to the gallery 12 into which the pressurized gas is fed via a pipe 38 and a valve 40, a pressure relief valve 42 is provided in the gallery. In order that different measured quantities be dispensed from the apparatus, electrical probes 48, 50, 52, 54, and 56 are inserted into the top of the cylinder and arranged at different depths. In operation, in order to dispense a certain quantity, the appropriate probe is first selected via a switch in the electrical circuit and the gas fed into the gallery until a pressure-actuated switch 44 is closed. A main on/off switch is then closed thereby actuating a solenoid-actuated valve 28 to open the liquid inlet 24 and, simultaneously, closing a solenoid-actuated valve 30 in the outlet pipe 31. The liquid then rises in the cylinder until the liquid contacts the end of the selected probe, thereby completing an electrical circuit so as to close the inlet valve 28 and open the outlet valve 30 to dispense the liquid. Due to the gas pressure acting on the top of the liquid as it rises in the cylinder, frothing is prevented. In order to clean the apparatus, the probe 56 is selected and a detergent fed into the cylinders. Several dispensing cylinders may be connected to a common gas gallery and a counting device included in the apparatus.

In a motor vehicle gear shift linkage wherein movement of a manual shift lever 1 is transmitted through joints 11, 13 and a shaft 16 to an axially slidable and rotatable shift rod 3, each joint comprises a block 25 universally pivoted to the shaft 16 and a ring 17 axially movable with and rotatable relative to the block 25 which ring and block carry arms 28, 39 respectively connected to a rotatable and an axially slidable part of the shift lever or shift rod mechanism. Axial movement of a link 47 between the shift lever 1 and arm 39 of the joint 11 produces rotaty movement of the shaft 16 which is transmitted through the arm 39 of joint 13 to move the shift rod 3 axially, whilst rotary movement of a sleeve 43 fast with the arm 28 moves the ring 17 and shaft 16 axially. This axial movement pivots the arm 28 of joint 13 about the shift rod 3 to which the arm is splined and thus rotates the shift rod. The shaft 16 is universally pivoted to the block 25 by cylindrical pins 31, 35 respectively pivoted between forks on the shaft 16 and block 25 and which pin 35 passes through a hole in the pin 31. A bolt 37 passes through the block 25 and pin 35 into the arm 39 which it secures to the block 25.
