Title: Apparatus for separating solid particles from a liquid
IPC: C02F3/12
Filed: 1969-03-18
Abstract: 1,268,271. Treating liquids containing solid matter. WESTINGHOUSE ELECTRIC CORP. 18 March, 1969 [25 March, 1968], No. 14108/69. Heading C1C. Liquids containing solid particulate matter are aerated in a chamber 14 and subsequently treated with bubbles of an oxygen-containing gas in chambers 24 which carry the particles to the surface of the liquid, the bubbles of air used in the aeration being larger than the bubbles of oxygen-containing gas. The liquid containing solid particles is passed through an inlet pipe 10 and a comminutor 12 into the chamber 14 in which it is aerated by diffusers 16 supplied with air from a manifold 22 connected to air blowers 20. The aeration causes the particles to follow a helical path in the chamber 14. After aeration, the liquid enters an airlift comprising a pipe 26 and a pump 28 connected to the manifold 22 and passes to the chambers 24 via a cleaning junction 32, conduits 36, (40), Fig. 2 (not shown), inlet boxes (42) and feed pipes 44. In the chambers 24, the liquid flows in series through compartments (46). The oxygen-containing gas introduced into the chambers 24 may be air forced through a diffuser or a mixture of hydrogen and oxygen generated by electrodes 50. The clarified liquid from the chambers 24 is passed through a conduit (54) into an effluent box 52 from which it is discharged via a pipe 56. A stopper 62 engageable with the inlet of pipe 56 and operable by a solenoid 58 and a timer controls the level of liquid in the box 52 and the chambers 24. Any solids deposited in the bottoms of chambers 24 are removed via pipes 53 when an airlift line 55 is actuated. When the level of liquid is allowed to rise in the chambers 24, liquid and the solids flow over a lip (66), Fig. 3 (not shown), into a digester 68 which is supplied with air from diffusers 70 connected to the manifold 22. The digester 68 has an outlet pipe 72 connected to an airlift line 74 which is fed from the manifold 22 via a line 76. The outlet pipe 72 returns liquid to the aeration tank 14. A hypochlorinator 80 may pass chlorine from a storage tank 78 into the chambers 24.

Title: Improvements in cord making devices
IPC: D07B3/12
Filed: 1924-06-16
Abstract: 230,688. Romer, C. June 16, 1924. Model machines.- A cord is made from wool, silk, cotton, raffia, wire, &c., and is manufactured on a kindergarten toy by attaching the strands to hooks h, Fig. 1, on spindles, which are rotated in a frame b by an endless belt y passing over pulleys s, the other end of the strands being attached to a common weighted hook r. As the spindles are rotated, a grooved guide m between the strands rises and a cord is formed below the guide, the hook r spinning freely. As shown in the drawings, the frame b is adapted to be secured to a door or wall, and a bar n on the guide, by bearing against the wall, prevents the guide m from rotating. For manufacturing continuous lengths of cord the strand material is contained on bobbins t, Fig. 2, and passes through hollow spindles where it is held by clamps u. A finite length is manufactured as described above and then more strand material is pulled through the spindles and the operation repeated. The machine may be used horizontally instead of vertically, in which case the hook r contains a swivel and is weighted by a cord passing over a pulley to a weight.

Title: Improvements in machines for packing cigarettes
IPC: B65B19/02
Filed: 1927-05-30
Abstract: 272,210. M³ller, J. C. June 4, 1926, [Convention date]. Packeting cigarettes in cartons.-Relates to apparatus for packing cigarettes in shells, the cigarettes being first fed transversely of their length, assembled, and then fed in the direction of their axes into the shell. A series of hoppers 1, Figs. 1 and 3, are arranged from which the cigarettes are fed in three parallel tracks to beneath rotatable cover plates 30. The bottom of each hopper comprises an endless belt 3 which forwards the cigarettes, which may be oval, past an agitating device 14 to a fluted drum 4. From the drum they pass over a plate 22, forked to pass into peripheral grooves in the drum, to an endless band 24, beneath a fixed cover plate 29 and a rotatable cover plate 30, the foremost cigarettes being arrested by an abutment 35. The cover plate 30 forms one of a series of four arranged on each spindle 31. The abutment is so formed and 'the distance between the cover plate and the band is arranged to cause the cigarettes to assume the overlapping formation shown in Fig. 3. The leading group of cigarettes is then engaged and moved in the direction of their axes by a pusher 37, Fig. 2, actuated bv a chain 38. The pusher also engages the rotatable cover plate 30 and turns it through a right angle so that the belt 24 is again covered by the next succeeding plate 30 on the spindle 31, Fig. 3. A presser 41 rises and holds the remaining cigarettes stationary while the foremost batch is fed away. The batch passes over a table 36<1>, Fig. 2, and above another batch of cigarettes fed by a second belt 24. The path of the chain 38 is stepped to enable the pusher 37 to descend and engage, the two batches to feed them over a table 36<2> and above a third batch. The pusher 37 again descends and engages the three batches and pushes them into a slide Z. The three feed bands 24 are arranged at different levels as shown in Fig. 2 to allow the superposing of the batches, and each rotary cover plate 30 is turned through a right angle by the passage of each pusher 37. In the event of the supply of cigarettes beneath a fixed cover plate 29 failing, a feeler 54, Fig. 3, descends through a gap in the plate and allows contacts 61, 62 to meet and to close a circuit by which the speed of the feed drum 4 is accelerated. The feeler is lifted at each cycle of the machine by a cam 55 and lever 53, but the circuit may be so arranged that the acceleration of speed is initiated by the meeting of the contacts, but is not retarded by the subsequent breaking thereof. The filled slide is fed in a longitudinal direction for insertion in a casing.

Title: Improvements in or relating to apparatus for testing lip seals
IPC: B07C5/04
Filed: 1961-04-24
Abstract: 909,695. Pneumatic gauging of lip seals. GENERAL MOTORS CORPORATION. April 24, 1961 [May 2, 1960], No. 14695/61. Class 106 (2). Apparatus for testing lip-seals, and rejecting those outside a given tolerance, comprises a rotatable table 16 having recesses 28 embracing the seals (which are fed from a loading port 42) and a pneumatic gauging head, similar to 64b in Fig. 7, at each of three testing stations 46, 48 and 50, a rejection station (124, 126 or 128) after each test station, comprising a pneumatically driven rake (144, 144a or 144b), being operated if the air-flow in conduits leading from the gauging head reaches predetermined values. At the first station 46, a gauging head similar to 64b has an under-size stub shaft 82 which enters, with relatively loose fit, the annular seal 98, when the head is lowered (by pneumatic means). Excess air-flow past the flexible lip 102 will open a diaphragm-switch 470-472, responsive to a given rate of air-flow (Fig. 10), and via a system of electrical relays, energize a rejection-indicating lamp and cause rake 144 to be operated when the seal arrives at the adjacent rejection station. If accepted, the seal passes to the next test station, operating by its passage a micro-switch 158 to cause gauging head 64b to be lowered. An over-size stub shaft here will give too small an air-flow for a seal of too-small diameter with consequent rejection at station 126. Thus, seals having diameters within a certain tolerance arrive at test station 50. A gauging head, having a stub-shaft of the desired mean diameter, is lowered here. If the pressure of air passing the lip of the seal is too high, or too low, a rate-of-flow-responsive diaphragm switch 566 will operate, or leave unoperated, as the case may be, a relay 572 and switch 574. In either case, a circuit is made via lead 578 or 580 to operate the next rejection station, if a pressure switch 586 is at an extreme position. Within the desired tolerance on the pressure, the spring-loaded pressure switch 586 will float, and the seal will be accepted, passing to an ejection shoot 164 along which it is urged by a springy arm 166. Counters are provided at each of the rejection shoots 130, 132, 134 and at the acceptance shoot 164. The pneumatic circuit is controlled by an electrically operated timing device co-operating with a system of exhaust valves for retracting the gauging heads and rakes, a system of four-way values being included to hold a gauging head inoperative if the preceding rejection station has rejected a seal. A rejection circuit can only be energized if the preceding gauging head has descended, thereby closing a master switch.
