Patent GB-1212699-A (GB)
Title: Method and apparatus for monitoring and sorting articles manufactured in mass production
IPC: B07C5/344
Filed: 1967-12-28
Abstract: 1,212,699. Sorting batteries and cells. SOC DES ACCUMULATEURS FIXES ET DE TRACTION. Dec.28, 1967 [Dec.28, 1966], No. 58959/67. Heading G1U. A method of sorting mass produced articles includes measuring one particular characteristic of each article or of one or more samples in a batch of articles and comparing the measured value with the mean value A of the same characteristic of a plurality of previously sorted articles or samples, the mean value being increased or decreased to a new value A<SP>1</SP> whenever the measured value exceeds A+a or falls below A-a, respectively, "a" being an arbitrary constant, the range changing to A<SP>1</SP>Œa when A changes to A<SP>1</SP>, and rejecting an article whenever the measured value falls outside the range AŒr, "r" being an arbitrary constant greater than "a", the range changing to A<SP>1</SP>Œr when A changes to A<SP>1</SP>. In sorting Leclanche cells, the e. m. f. Ai, Fig. 3, a cell is compared with the median A of the end's of a plurality of previously sorted cells, and an output pulse of 50m sec. duration representing the difference is fed to a unit B, also supplied by a multivibrator C operating at 2000Hz, the output of B being a train of pulses oscillating about zero and having a phase shift dependent on the polarity of the 50m sec. pulses. The output of B is fed through a preamplifier E to a rejection channel 14 and a phase converter F which produces complementary signals, one in phase with and the other out of phase with the output of unit B, the outputs of F being respectively amplified at G1, G2 and passed to demodulators H1, H2, one of which, depending on the polarity of the 50m sec. pulse, produces a negative d.c. voltage. If Ai exceeds A, H1 produces the negative voltage, which, if Ai exceeds A+a, is sufficiently large to overcome the threshold of a Zener diode associated with a threshold circuit S1, thus feeding a train of pulses to an integrator I1 causing an adjusting device T1 to increase A. The integrator prevents A being changed by noise signals. Channel 16 operates if Ai falls below A, causing T2 to reduce A if Ai falls below A-a. Rejection channel 14 is similar to channels 15, 16 but includes a timing circuit 17 which controls the openings of a trap door 18 where the defective cell reaches it. The invention is also applicable to sorting articles according to their physical dimensions.

Title: Once-through vapour generator
Inventor: CORZEGNO WALTER PAUL
IPC: F22B29/10
Filed: 1969-12-31
Abstract: 1294120 Vapour generators FOSTER WHEELER CORP 31 Dec 1969 [28 Jan 1969] 63573/69 Heading F4A A vapour generator, Fig. 1, comprises a furnace 12 formed by parallel tube wall panels 14, 16 which define a first upward flow pass and in series flow relationship therewith parallel tube wall panels (18), (20), Fig. 2 (not shown), defining a second downward flow pass. The generator is heated by gas, oil or coal fired burners E, the gases from which pass through an exit end C to a heat recovery area D which is divided into front and rear passes 48, 50 respectively by a partition wall 36 and contains superheaters 55, 30, 52, a reheater 54 and economizer 56. The gases flow through an air heater H to heat incoming combustion air for the burners E. Liquid to be vaporized leaves economizer 56 and via a downcomer 58, Fig. 3, passes to headers (60), (62) and flows up the tube walls 14, 16 to leave through headers 60a, 62a. A fan-mix arrangement, Fig. 5 (not shown), comprising a horizontal manifold (92) and numerous connections (96), (98), mixes and disperses the flow of liquid before it flows through a downcomer 66 to headers (68), (70). The liquid flows up the sidewalls (18), (20) through a fan-mix arrangement 72 formed by manifolds 74, 76 to the heat recovery area D. Here it flows through tube walls 36, 40, 44, 46 and sidewalls 38, 38a of a portion 32 formed by a screen of tubes 28 to the generator roof 22, heat recovery area rear wall 42 and superheaters 52, 55, 30 respectively. Part of the flow from downcomers 58, 66 is fed to a buffer circuit, Fig. 2A (not shown), formed by tube panels 80, 82, 84, 86 in the corners of the furnace 12. The buffer circuit partly reduces the stresses in the tubes due to differential thermal expansion by establishing a temperature between that of the first and second passes. To maintain high flow rates and reduce the pressure drop in the furnace the latter is divided into a lower highabsorption zone B<SP>1</SP>, Fig. 4A (not shown), and an upper lower temperature zone B<SP>11</SP>, the tube diameters increasing at a point 2/3 the height of the furnace. In a second embodiment, Fig. 8 (not shown), a larger furnace totally oil fired has the side walls divided into second and third passes (110), (112) with a mixing header (114) therebetween. In a final embodiment, Figs. 11, 12 (not shown), a division wall (120) is provided between front and rear walls (122), (124), the liquid flowing via downcomers (130), (132) to both the walls (122), (124) and the division wall (120). The embodiment of Figs. 11, 12 may be incorporated into that of Fig. 8. Graphs of temperature es. enthalpy, Figs. 9, 10 (not shown), are also described.
Patent GB-708258-A (GB)
Abstract: 708,258. Fluid-pressure servomotor-control systems. DE LA RUE & CO., Ltd., T. Feb. 13, 1952 [Feb. 16, 1951], No. 3882/51. Class 135 A gas burner safety system comprises a main burner 8, a pilot burner 3 supplied from the mains, a safety cut-off valve comprising two chambers, one containing the valve 7, seat 6, and a leak 20 to the burner, and the other a diaphragm 12 which co-operates with a bimetal actuated valve 16 controlled by the pilot, and a control cock 21 between the one chamber and the burner. With the valves 5 and 21 open as shown mains gas pressure at 1 acting on the valve 7, together with the weight 13, closes the valve since gas leaking via 20 downstream of the valve escapes through the burner 8 or via passage 19, the space below the diaphragm 12, pipe 14 and the open valve 16 to atmosphere. On lighting the pilot 3 the bi-metal element 17 is heated and closes the valve 16 but because the passage 19 is open to atmosphere via the burner the diaphragm and valve 7 remain in the closed position. On manually closing the valve 21, the gas pressure rises beneath the diaphragm 12 and opens the valve 7 and then on re-opening the valve 21, gas passes to the burner. Should the gas pressure fail or the valve 5 be closed, the above lighting process must be repeated. The burner flame may be turned on or off by the valve 21 without affecting the diaphragm or valve 7. The stem of the valve 7 is sealed by a bellows 11 to a partition 9 of the diaphragm chamber.
Patent GB-712567-A (GB)
Abstract: 712,567. Transfer mechanism. BEAVIS, E. T. (National Registrier Kassen Augsburg Ges., and Philipp, O. M.). July 16, 1952, No. 17957/52. Class 106 (1) Tens transfer mechanism in a totalizer comprises, for each order, a preparatory member which is actuated by a transfer tooth on the totalizer wheel as it passes from " 9 " to " 0 " and a rotary multiple-toothed transfer member which is initially actuated by the preparatory member of next lower order at each actuation of the latter, and includes a cylindrical actuator having a series of apertures adapted to receive teeth of initially actuated transfer members and thereafter further to actuate them in sequence by means of helically disposed effective edges of the apertures to effect transfers. At transfer, a transfer tooth 2a on the lower order totalizer wheel rocks a bail 7 against the action of a torsion spring 23, and a lateral extension 10 of the bail rocks a star-wheel 11 associated with the next higher order into the preparatory position shown in which one of its points enters a corresponding aperture in an actuating sleeve 16. A detent arm 21 loaded by the spring 23 prevents return of the star-wheel. When the totalizer has disengaged the actuators, the sleeve 1 is rotated clockwise and the star-wheel is thereby rotated further counter-clockwise, engaging the higher order totalizer wheel to advance it by one step. A detent 25 co-operates with each totalizer wheel. The apertures in the sleeve 16 progressively increase in size from the tens order upwards, the camming edges 17 becoming effective at progressively later points in the operation so that transfers take place seriatim. The shaft 14 on which the sleeve 16 is secured is drilled to provide apertures 15 to permit rotation of the starwheel. The apertures in the sleeve 16 and shaft 14 are divided into two portions in the higher orders to permit immediate transfers to take place early in the rotation of the shaft and transfers resulting from transfers in the lower orders to occur towards the end of this rotation.

Title: Apparatus for Detecting Defects in Glass Containers
IPC: B07C5/12
Filed: 1980-02-26
Abstract: The apparatus is especially designed to detect "birdswing" defects and comprises a linescan photodiode array camera (6) which views light refracted from a rotating container under inspection (2), the light being produced by a source of illumination (4). The photodiode array is linear and disposed parallel to the longitudinal axis of the container. Any defects such as birdswings will show as dark areas on a normally light background. Electronic circuitry is provided enabling the user to preset the number of camera scans and the length of the diode array over which the dark area exists before a defect present signal is produced. This provides a control to the minimum dark area which must exist on the container before a defect is signalled and prevents minor blemishes from triggering such a signal.   <IMAGE>
