Title: Measurement of glass tubes
IPC: C03B17/04
Filed: 1962-11-14
Abstract: 979,480. Measuring glass tubes photo-electrically. CARL ZEISS-STIFTUNG. Nov. 14, 1962 [Nov. 16, 1961], No. 43067/62. Heading G1A. The invention relates to a method of, and apparatus for measuring the external diameter of glass tubes, in which a glass tube 4 whose diameter is to be measured is passed through a measuring beam 3 produced by an ultraviolet lamp 1, and the radiation intensity of the beam with the tube 4 interposed in the beam is measured by a photo-electric cell 7 connected to a measuring instrument. In the embodiment shown ultraviolet radiation from the lamp 1 is collimated by a quartz glass lens 2 and directed through a filter 5 which transmits only the required short wave radiation to a further quartz glass lens 6 which concentrates the radiation on to a photo-electric cell 7 connected through an amplifier 8 to the measuring instrument 9. The tube 4 under investigation continuously passes in the direction of its longitudinal axis through the parallel portion 3 of the ultraviolet beam. To compensate for example, for fluctuations in the radiation intensity of the lamp, a comparison beam 11 is directed through an ultraviolet filter 13 and a further quartz lens 12 on to another photo-electric cell 10 the output signal from which is fed through an amplifier 14 and compared in the instrument 9 with signals from the photo-cell 7. The indication of the instrument is preferably initially matched to a glass tube with a nominal diameter after which deviations from this diameter of a tube under investigation are indicated. A diaphragm may be provided to stop the measuring beam to a suitable size so as to enable the tube 4 to be moved in the beam in a direction perpendicular to the path of the beam without affecting the amount of radiation obscured by the tube.

Title: Dispensing of articles
IPC: B65B57/20
Filed: 1971-09-21
Abstract: 1343993 Batch dispensation of articles MATEO GRAU E HIJOS SA F M SOLER and J S GOMEZ 21 Sept 1971 [21 Sept 1970] 44049/71 Heading B8C In a process for counting out a predetermined number of articles, such as oranges 3 for packaging, from a supply previously sorted into groups according to weight, size &c., compensation is made for there being more articles in one, or more, of the groups by providing different programmes for controlling a dispensing device 4 so that the number of oranges fed from each group to contribute to a package containing the predetermined number of oranges can be varied, in dependence upon the group, or groups, containing the maximum number of oranges. As shown, oranges 3, previously sorted into five groups according to weight, are circulated by mechanism 40, along five feed channels 2 each having indicating means 5, 6, respectively, for indicating maximum and minimum number of oranges in the channels and for supplying signals to a first electronic circuit 7, the means 5 also being connected to a second electronic circuit 8 comprising an automatic programme selector 9 having as many programmes as there are channels 2. When all of the channels 2 contain at least the minimum number, and one of the channels contains a maximum number, of oranges each indicating means 5, 7 supplies a signal to the first electronic circuit 7 which, according to the programme set by the electronic circuit 8, triggers the starting operation to order the dispensing device 4 to free a predetermined number of oranges from each channel 2 and make up a package. When more than one channel 2 contains the maximum number of oranges, the circuit 7 triggers cessation to the feed and the electronic circuit 8 orders the dispensing device 4 to perform a different counting programme to free a different combination of oranges from the channels. The device 4 comprises a rocking portion 10 at the end of each channel 2 and a plurality of retaining elements 11a, 11b, 11c mounted on a pivotal arm 13 associated with each channel, each of the flexible rods 12 of the elements 11a, 11b being retractible when a magnet (31), Fig. 4 (not shown), is magnetized, and the flexible rod 12 of the element 11c being fixed. The electronic circuit 8 orders the dispensing device 4 by controlling a motor 21a and crank 21 which, through links 20, 18, 16, raises and lowers the arms 13 and, by supplying pulses to the electromagnets 31, 28 which control, respectively, the elements 11a, 11b and the rocking portions 10.

Title: Illumination systems in electrophotographic printing machines
IPC: G11B23/50
Filed: 1975-10-29
Abstract: 1523917 Making colour separation images XEROX CORP 29 Oct 1975 [10 March 1975] 44655/75 Heading G2A Apparatus for illuminating an original 32 in, an electro-photographic copying machine, includes a light source (lamps 24 on a carriage 80) illuminating the original, means for interposing differently coloured filters 30 selectively into the light reflected from the original, and means, responsive to the colour of the selected filter, for controlling the excitation of the light source. As shown in Fig. 2, lamps 24 may be xenon lamps, and their carriage 80 moves along the original 32. Light from the original is reflected by mirror 36 through a lens 28, and is reflected by mirror 38 to form an image on the photo-sensitive surface 12 of the rotating drum 10. Filters 30 and lens 28 have a common support which is moved at a speed correlated with that of carriage 80 to produce a flowing image moving at the same speed as surface 12. Filters 30 may comprise red, green and blue filters brought each in turn into the light beam, so that three colour-separation images are formed in sequence as latent electrostatic images on the surface 12. These images are developed as coloured powder images, which are transferred in superimposition on to a carrier in the usual way. A slotted disc 16, Fig. 3, on the same shaft as drum 10, is placed between a lamp 18 and a photo-cell 20 whereby pulses are generated as the disc rotates. These pulses are fed to a counter 82. 88, 90 are AC mains input terminals. At the first pulse, when the green filter (say) is in position, the counter 82 sends a signal to a controller 84, whereupon the controller causes a supply circuit to supply current to the lamps 24 at a voltage such that the brightness of the lamps is appropriate to the green filter, if the exposures required for the filters are to be equal. At the eleventh pulse, the green filter is replaced by the red filter, and counter 82 sends a signal to controller 84, which alters the output voltage to a value appropriate to the red filter. Finally, the red filter is replaced by the blue filter and, as before, the supply voltage is changed to the voltage appropriate to the blue filter. After exposure through the blue filter, the apparatus is ready for a new cycle.

Filed: 1961-12-16
Abstract: 950,234. Thermal storage heaters; ventilation. PARKINSON COWAN Ltd. Dec. 13, 1962 [Dec. 16, 1961], No. 45181/61. Headings F4U and F4V. A thermal storage heater, in which atmospheric air is passed through or over a mass of preheated material, has at least two separate outlets, facing in different directions, for the heated air, at least one of which can be shut off when desired while the other remains open. As shown, Fig. 2, the heater 10 stands on a plinth 26 against a wall 29 dividing two rooms to be heated. A fan, not shown, draws air into the heater, and passes it through an entry chamber 17, round refractory heat storage blocks 14 arranged in a compartment 13, and into a discharge chamber 18. Heated air leaves the discharge chamber through a louvre exit 23 into one room, or through a slot 31, a duct 27 in the plinth 26, and a louvre exit 28 into the second room. A valve 20 in the wall 19 dividing chambers 17 and 18 is controlled by a bimetallic element 21 in the chamber 18 so that it opens to allow unheated air to pass directly into chamber 18 when the heated air temperature exceeds a predetermined value. Division of the heated air between the two outlets is controlled by means of a flap valve 33 pivoted on a rod 34 and having a cut-out portion 36, Fig. 3, to avoid fouling the bi-metallic element 21. A control knob 41, Fig. 3, is connected to the valve rod 34 by a cord 38 having a tensioning spring 42. A notch disc 43 engaged by a sprung detent 45 enables the valve to be held in a number of intermediate positions. The valve 33 may be controlled automatically, e.g. in response to a thermostat in the room in which the heater is situated. The invention may be applied to existing single outlet storage heaters, a flap valve and base slot being added, and plinth 26 being provided.

Abstract: 1,133,598. Hydraulic and mechanical brake system. FORD MOTOR CO. Ltd. 18 Oct., 1966 [2 Dec., 1965], No. 46490/66. Headings F2E and F2F. In a motor vehicle brake system the brakes of all the vehicle wheels are adapted to be applied through an hydraulic master cylinder system 29, 30 and through a mechanical linkage 50, 56, 24 the brakes 22 of the rear wheel are adapted to be actuated such that an element in the mechanical linkage is movable at the will of the driver into a first position in which there is lost-motion in the mechanical linkage such that movement of the brake pedal 26 applies the brakes by means of the hydraulic master cylinder system before the brake pedal begins to apply the brakes through the mechanical linkage. The element in the mechanical linkage consists of a projection 52 provided on a rod 50 pivoted to the brake pedal 26 wherein the projection 52 is slidable in a slot 54 in the brake lever 56 and is located in its first position by means of a stop pin 68 which is spring loaded and under the control of the driver of the vehicle such that, on depression of the brake pedal 26 in a clockwise direction, the rods 48 and 40 of a mechanical connection 34 between the brake pedal and the master cylinder actuate the master cylinder 29 to pressurize the brake cylinders 20 on all the brakes on the vehicle. The simultaneous movement of the link 50 to the left is accommodated by the lost-motion movement of the projection 52 to the left in the slot 54 of the lever 56 without causing any anticlockwise rotation of the lever 56. The brakes of the vehicle are applied solely by the hydraulic system, the mechanical system at this time being inoperative. Should a failure occur in the hydraulic system, continued depression of the brake pedal 26 moves the projection 52 into contact with the left hand end of the slot 54 so that the lever 56 is rocked anti-clockwise to apply the vehicle brakes mechanically through a Bowden wire connection 24. To apply the emergency brake for parking purposes, the driver pulls out a knob attached to the stop pin 68 and the retraction of the pin 68 permits-the projection 52 of the rod 50 to move to the extreme right-hand end of the slot when the brake pedal is biased in an anti-clockwise direction to the dotted line position 37 shown in Fig. 1. In this position the rod 48 is moved to the right to provide a clearance between it and the rod 40 and the operator then releases -the knob controlling the stop pin and a spring moves the pin into the slot 54 to lock the-projection 52 of the rod 50 in the position indicated by the dotted lines 82 to provide a direct connection between the rod 50 and the lever 56 through the pin 68 without causing actuation of the hydraulic braking system. A suitable locking mechanism may be associated with the brake pedal to hold the pedal in the selected position until released by the vehicle operator.
