Abstract: 1,088,522. Conveyers. A. T. KORNYLAK. Feb. 19, 1965 [Sept. 8, 1964], No. 7187/65. Heading B8A. A package handling system comprises a gravity type rollerway 33 for feeding single packages to a forwarding escapement 32 which prevents overloading of a loader assembly 21. Each package is moved from a pick-off conveyer 21<SP>1</SP>, through 90 degrees, by a transfer conveyer 22, pivotable about axes 210. The conveyer 22 transfers the package to an endless chain elevator 23 from which the package is picked off by a roller conveyer (175), Fig. 6 (not shown). Means on the elevator 23 and the transfer conveyer 22 co-operate to cause the conveyer 22 to remove the package from the pick-off conveyer 21<SP>1</SP>. The conveyer 22 and forwarding escapement 32 co-operate to cause operation of the escapement. Forwarding escapement 32; Figs. 5, 13 (not shown).-A frame (70), rockable about a pivot (71), carries driven rollers (73), (77) and an idler roller (72). The frame also carries a roller (98) which engages the frame (43) of the transfer conveyer (22) when the latter is rocked to the position indicated in Fig. 3 (not shown). A package (P) resting against a stop (76<SP>1</SP>) is then lifted, by a stop and roller (74, 76), over the stop (76<SP>1</SP>) and moves on rollers (36) of the pickoff conveyer (21<SP>1</SP>) to a stop (141). Loader assembly 21, Fig. 2 (not shown).- This includes the transfer conveyer 22 which comprises rollerways (40, 42) driven by a roller (44); rollerways (38, 41) have idler rollers (45). The frame (43) of the conveyer 22 carries spaced fingers (139, 140) which are engaged by cam rollers (138), Fig. 3 (not shown), provided on carries (113) of the elevator 23. The tilting of the frame (43) is controlled by a dashpot (163). Elevator 23, Figs. 6-9 (not shown). -Carriers (113) are mounted on chains (100) and are maintained in position by bell crank levers (115) having rollers (118, 119) which ride in grooves (120, 121). Each carrier comprises idler rollerways (127) and driven rollerways (128), the rollers (130) of the latter being driven by a roller (68). Downward movement of a carrier causes the frame (43) to pivot and raise that section remote from the spaced fingers (139, 140). Since at least some of the rollerways of the transfer conveyer 22 are driven, a package will be passed on to the carrier and against a stop (142). Safety device, Fig. 3 (not shown).-Should a package not be properly placed on a carrier (113), a microswitch (185) will be actuated by a switch arm (180) and the system will be closed down.

Title: Improvements in or relating to the control of the tension of moving webs, cords, wires and like materials
IPC: B65H23/04
Filed: 1938-09-29
Abstract: 521,838. Automatic control systems for moving coils. HOLMES & CO., Ltd., J. H., KASSELL, E. D., and WALTON, J. W. W. Sept. 29, 1938, No. 7297/40. Divided out of 520,727. [Class 38 (iv)] Tension in moving webs such as paper and other strip material, cords, wires &c. is maintained constant by an electronic valve the output of which is used to control'the rate of supply and/or take-up of the moving material. A jockey roller or other follower displaced in accordance with variations in the tension causes variation in the timing of electrical impulses applied to the grid circuit of the valve. Gas discharge or vacuum valves may be used. A transformer L<SP>4</SP> supplies current to the anode circuit of a valve L<SP>3</SP> which includes for example a solenoid A<SP>4</SP> controlling the force applied on a brake A' loading the working material A or the shunt winding of a tension control motor acting upon a stop which bears upon a web roll. Current is likewise supplied to a grid bias potentiometer L<SP>2</SP> and this bias is periodically removed at an instant in each cycle depending on the tension in the material. A block K<SP>2</SP> may be adjusted in relation to a commutator driven by a synchronous motor K<SP>9</SP> by movements of a jockey roller B so that contacts on the block are short-circuited by a shaped conducting plate K' to remove the grid bias and ignite the valve at the instant in each cycle requisite to maintain the tension constant. The jockey roller may be spring or weight controlled or counterbalanced and the tension may be adjusted by varying this control force or the potential applied to the transformer L<SP>4</SP>. Single phase full-wave rectifier arrangements and a three-phase half-wave rectifier arrangement are described. Arrangements using cam-driven interrupters adjustable about the axis of the cam are described. The invention may be applied to control the speed of the A.C. commutator motor driving each section of a paper-making machine.

Abstract: 956,067. Radio navigation; transistor relay circuits. MINISTER OF AVIATION. Feb. 26, 1963 [Feb. 28, 1962], No. 7788/62. Headings H3T and H4D. A navigational aid calibration system comprises a camera having a shutter, means for defining a reference axis in space, means for providing characteristic outputs when, and only when, the optical axis of the camera lies within chosen angular limits with respect to the reference axis, means for connection to the output of the navigational aid and for providing a characteristic output when, and only when, output signals from the navigational aid lie within chosen limits and means for operating the camera shutter when, and only when, all of the characteristic outputs are present. The invention is described as applied to the calibration of a course line provided by an I.L.S. localizer beacon, by an aircraft carrying an I.L.S. receiver, providing D.C. outputs I 1 , I 2 , Fig. 1, a gyroscope G and a camera K such that if power is continuously supplied to its shutter it will wind on the film and take a fresh picture of the earth every 1.6 seconds. Relays A/1, B/1, C/1 control corresponding contacts in the camera control circuit; in order to guard against localizer transmission failure a threshold circuit, fed from the sum of currents I 1 , I 2  and incorporating a relay D/1, is provided. To limit the rate of taking pictures a slow-torelease relay E/1 is incorporated. The method of calibration is described and an error analysis is included. A transparent cursor is illustrated, Fig. 3 (not shown), and its use is explained, Fig. 4 (not shown). Transistor relay circuits, Fig. 2.-Push-pull D.C. outputs from amplifier A2 are applied to transistors Q1, Q2; when the roll angle is zero their emitter voltages are equal and relay B/1 is not actuated and contact B1 (Fig. 1) remains closed. When the roll angle increases in one sense so that the difference in the emitter voltages of the transistors rises to the reverse conduction voltage of Zener diode Z1, the latter conducts, Zener diode Z2 conducts and relay B/1 is energized. Similarly, when the roll angle increases sufficiently in the opposite sense the relay is energized.
