Title: Tobacco Rod Forming Method and Device.
IPC: A24C5/18
Filed: 1968-07-01
Abstract: 1,197,667. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. 1 July, 1968 [21 July, 1967; 27 Feb., 1968], No. 31353/68. Heading A2C. A method of forming a braid of cut tobacco particles comprises forming a thin layer of tobacco particles on a conveyer surface moving in a predetermined path and simultaneously collecting the tobacco laterally and transversely of said path in a progressive decreasing form converging into a narrow path along an axis parallel to its path of movement, thereby to form a single braid of tobacco. Cut tobacco is evenly showered on to an air permeable conveyer belt 1 across its whole width, as indicated by the long arrows B in Fig. 1. The belt 1 travels in the direction of the arrow A and passes over a suction chamber having an opening (7) of triangular shape extending to a longitudinal slit (8). A height adjustable Y-shaped covering 9 overlies the belt 1 where it passes over the suction chamber, in correspondence with the slit (8) and two sides (207) of the triangle of the opening (7). The suction applied through the belt 1 produces air flows, indicated by the short arrows 16, 116, which cause the tobacco to accumulate on the surface of the belt 1 underlying the arms of the "Y" to form two semi-braids that unite under the stem 109 of the "Y" to form a single braid for feeding to a cigarette-making machine. In another embodiment, Fig. 6, the conveyer surface is curved and comprises a suction drum 67. Tobacco, fed to and picked off a carding roller 62 in conventional manner, is fed in a wide stream by a conveyer 66 to the drum 67, stems and other heavy articles dropping away at C. The drum 67 is provided with a curved Y-shaped covering 70 and a curved triangular shaped suction chamber 69 equivalent to those used in the first embodiment. The tobacco leaves the drum 67 as a single braid which is transferred by an air permeable belt 78, in conjunction with a suction drum 76, to a conventional rod forming mechanism 80. The tobacco braid is optionally trimmed by a trimmer 83. The Specification also states that mechanical guides may be used to converge the tobacco path in place of the suction conveying device.

Title: Camera for use with detachable flash apparatus
IPC: G03B15/04
Filed: 1971-07-05
Abstract: 1359842 Photographic cameras AGFAGEVAERT AG 5 July 1971 [3 July 1970] 31439/71 Heading G2A A camera for use with percussive flash-cubes 8 is provided with a release lever 3 which is operable to free impact members 6 in an attached cube; with a spring 4 urging the release lever 3 out of contact with an impact member 6; with a drive lever 19 for driving the release lever 3 towards an impact member; and with a control lever 12 which frees the release lever 3 from the drive lever 19 so that the spring 4 can return the release lever to its initial position. In use, fitting a flash-cube 8 depresses an actuating member 17, thus pivoting a locking lever 15 and allowing the parts to take up the positions shown. Depression of a handle 24 pivots a lever 22, thus freeing the drive lever 19 to run down. The motion thereof causes the control lever 12 to move in direction B, and, since the lever 12 is pivoted on the release lever 3, also pivots the release lever 3 in direction C. A shutter opening blade 26 follows an extension 21 of the lever 19, due to a spring 28. Continued rotation of the drive lever 19 causes the control lever 12 to engage spindle 2 of the release lever 3 Fig. 3, (not shown). The levers 3, 12 then rotate together, an arm 5 of the lever 3 initiating the flash operation, while the lever 12 escapes from the extension 21. The spring 4 then returns the levers 3, 12 to their initial positions, while a spring 14 causes the lever 12 to press against the underside of the extension 21 Fig. 4, (not shown). In another embodiment Fig. 5, (not shown), the release lever (51) acts on a feeler lever (70) to initiate a flash operation. Insertion of the flash-cube (68) besides pivoting the locking lever (62) as before, also pivots the feeler lever (70) to sense whether the impact member (77) has already been operated. A signal tab is pivoted into the camera view-finder if the lamp is burnt out.

Title: Traffic control system and apparatus
IPC: G08G1/08
Filed: 1962-08-17
Abstract: 1,017,079. Road traffic signals. LABORATORY FOR ELECTRONICS Inc. Aug. 17, 1962 [Aug. 18, 1961], No. 31743/62. Heading G4Q. In a vehicle operated traffic control system an extendible green period is timed by a capacitor charging linearly as shown at 227, Fig. 6, and connected in series with an increasing bias voltage shown at 225, and the total voltage, shown at 228, is applied to trigger circuits which terminate the green period. In response to vehicle demands such as those shown at A1 and A2, the capacitor is discharged, but due to the increasing bias voltage the extensions granted are steadily reduced. When the total voltage is equal to the trigger voltage (shown as 160 volts) a first trigger fires and discharges the bias voltage (line 225) and allows the capacitor to continue charging along line 227-2 to time a passage time, at the end of which a second trigger fires and changes the traffic lights. Timing circuits.-The operation of the system is controlled by a line switch (Fig. 1, not shown) and in all positions, except the extendible green positions, D.C. is supplied to terminal 30, Fig. 3, to add a steady bias to the potential of the timing capacitor 121. The capacitor is connected to a cathode follower 125 the output of which is coupled to the charging circuit through two neon tubes 126 and 127 to provide a constant charging voltage and ensure linearity. The contacts LR-4 are normally closed and the output at 134 is connected to a trigger circuit F.3b which operates a relay AS which energizes a motor magnet to step on the line switch. In the extendible green positions relay LR is energized to change over contacts LR-4, and a bias circuit, Fig. 2 (not shown), is connected to terminal 30. A maximum time circuit, Fig. 4 (not shown), is also connected in circuit to limit the extendible period. In the absence of demand for change of right-of-way a relay VR (not shown) operates and prevents the bias and maximum time circuits from starting, and its contacts VR-3 short-circuit the input to F.3a to prevent this unit from working, so the green period continues until there is a demand for a change. When there is such a demand the bias at terminal 30 starts increasing in accordance with the charging of a capacitor in the bias circuit, Fig. 2 (not shown), and each time a vehicle is detected in the road having right of way'capacitor 121 is discharged through the vehicle operated contact AD-5 or BD-5. When the total voltage at point 134 is sufficient the trigger circuit F.3a fires and energizes relay PR which discharges the bias voltage and deenergizes relay LR, thereby switching the output at 134 to F.3b. When capacitor 121 charges sufficiently F.3b fires and energizes relay AS to step the line switch on to its next position; during this charging period contact LR-5 is open so that capacitor 121 cannot be discharged by operation of the vehicle contacts AD-5 and BD-5.

Hot fluids, such as hydrocarbon vapours from a cracking plant, are rapidly cooled by injecting, through a thermally-insulated tube, a stream of the hot fluid directly into a divergent spray of quench liquid in a chamber wherein the stream of hot fluid intersects the outer lateral surface of the divergent spray of quench liquid at an angle between 75 and 105, preferably at about 90, and the quench liquid contacts the walls of the chamber below the area of injection. In the apparatus shown, hot hydrocarbon vapours are injected through tubes 11, and hydrocarbon quench liquid is sprayed in through nozzles 14. Purging gas, such as steam or nitrogen, is introduced through inlets 18 into the annular spaces 17 surrounding tubes 11. The cooled fluid, quench liquid and vapourized quench liquid leave the apparatus through outlet IS. Carbon deposition and metal fatique are both less than in conventional quenching apparatus. The cooling of a hot fluid may also be carried out by injecting it through a single tube into two opposing sprays of quench liquid.
