Title: Improvements relating to electric incandescent lamps
IPC: H01K1/10
Filed: 1966-10-24
Abstract: 1,144,374. Electric incandescent lamps. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 Oct., 1966 [27 Oct., 1965], No. 47533/66. Heading H1F. An electric incandescent lamp contains a filament made of the carbide of one of the metals tantalum, zirconium and hafnium or of a composite carbide of two or three of these metals, at least a part of the surface of the filament being coated with carbon. The filament may be made by heating a coil of wire made from the appropriate metal or alloy to a black body temperature of between 2000‹ and 2100‹ C. in a continuous flow of methane, ethane or propane, at 5 mm. pressure until carburization has been completed, and then reducing the temperature to 1600-1700‹ C. and increasing the pressure to 60 mm. to deposit a layer of carbon. The filament is heated by passing an alternating current through it, and deposition of carbon on parts of the filament can be prevented by shielding these parts with a negatively biased grid or a plate of mica. The thickness of the carbon layer can be varied over the surface of the filament by suitably directing the flow of gas. The filament is mounted in a lamp bulb by screwing its ends on to molybdenum mandrels welded to tungsten lead-in wires, and the bulb contains a reactive transport gas such as fluorine, chlorine, bromine, iodine, hydrogen or nitrogen, together with a catalyst if required. In the preferred embodiment the bulb contains argon with a small quantity of hydrogen.

Title: Improvements in or relating to apparatus for feeding rod-like articles such as cigarettes
IPC: A24C5/356
Filed: 1968-10-09
Abstract: 1284873 Hoppers feeding cigarettes to endless belt conveyers MOLINS MACHINE CO Ltd and T ROWLANDS 8 Oct 1969 [9 Oct 1968] 47822/68 Heading B8A Cigarettes in tray 1 are discharged into hopper 2, the fall of the cigarettes being governed by the downward movement of platform 6 and are fed away by belts 3, 4 which, with the aid of belt 13, convey the cigarettes on to discharge belt 7. The action of belts 3 4 is intermittent so that cigarettes pile up at the entrance to belt 7, the pile-up being permitted by the upward movement of pivoted arms 9, 10. Thus, platform 6 moves downward to permit the fall of cigarettes to the lower position shown and then moves at right angles and is raised outside the hopper to the original position, the movement being controlled by switches 14 and 15. Conveyers 3 and 4 move the cigarettes leftwards, the conveyer 3 moving slower than the conveyer 4 whilst conveyer 7 moves continuously. Arms 9 and 10 pivot upwards and downwards as the movement of cigarettes increases and decreases, to form a variable capacity reservoir.

Filed: 1975-11-20
Abstract: 1527514 Angle measuring instruments DR JOHANNES HEIDENHAIN GmbH 20 Nov 1975 [20 Nov 1974] 47825/75 Heading G1F Angular readings of a rotatable circular scale K are displayed by two optical objectives O 1 , O 2  mounted at the ends of bell-cranks H 1 , H 2  respectively at a distance x from the pivot points of the bell-cranks, pivoting being effected by an adjustment screw D to move the objectives along their scales (the bell-cranks are inter-conntected pivotally with a lever A). In use, screw D is adjusted until the scale graduation line scanned by objective O 1  (the scale representing whole degrees of arc) coincides with the line scanned by objective O 2 , (representing e.g. 10' arc; the amount of adjustment is measured by a scale T linked to the bell-crank H 1  by a lever H3 and provides an interpolation value of the 10' arc scale.

Filed: 1969-09-30
Abstract: 1287956 Selective signalling GENERAL ELECTRICAL CO 30 Sept 1969 [2 Oct 1968] 48046/69 Heading G4H The length of a piece of hot metal 11, Fig. 1, is measured by scanning the metal by means of a rotating polygonal mirror 19 and an infra-red radiation detector 25 in order to produce a signal "hot metal present", which gates 55, Fig. 2, clock pulses derived from an oscillator synchronized with the rotating mirror, to an accumulator 59. "Scan location pulses" for synchronizing purposes are produced by a light source 29 and a photo-electric cell 27. In order to compensate for non-linearities inherent in the scanning process the clock pulse train is also made non-linear. This is achieved by applying the pulses from an oscillator to a scan increment counter 53, which is arranged at specific counts, determined emperically, to delete some of the clock pulses from the oscillator that are actually applied to the count gate 55. The scan increment counter 53 is also used to check that the oscillator is correctly synchronized with the scanning mirror since at the end of each scan, that is to say when a scan location pulse occurs, it should be full to capacity, and any departure from this state causes a corresponding correction to be made to the oscillator frequency. Corrections for the thickness of the metal, and for the height of the scanning mirror above the metal support rollers 15, is also said to be made by means of a sealer 63 which is arranged to delete an appropriate proportion of the clock pulses that pass through the count gate 55 before they reach the accumulator 59. The taking of a measurement is initiated by a signal 67 and normally this causes twelve scans of the metal to be made before the contents of the accumulator 59 are displayed. However operation of the system is monitored 57 and unless the twelve scans are performed correctly then no display is made. The reasons for preventing the display of the accumulator 20 include detecting the presence of metal outside the measuring range of the system, and detecting metal twice within one scan within the measuring range of the system (this phenomenon indicating that the radiation path from the metal to the infra-red detector has been momentarily interrupted).
Patent GB-483475-A (GB)
Abstract: 483,475. Workmen's time-recorders. STANDARD TELEPHONES & CABLES, Ltd., and LOVEDAY, W. A. Oct. 16, 1936, No. 28180. [Class 106 (iv)] In a workmen's timerecorder of the kind in which time is recorded on an inserted card, the workman can also insert a plate carrying type whereby his name and number are printed on the card. A further plate bearing type representing the week-end date may be inserted and adjusted to either of two positions, so that one record card can be used for a period of two weeks. The record card is placed on a carriage 6 slidably across the front of the machine (from left to right in Fig. 2) to position different card columns under the time-printing wheels 2. The carriage is moved by a handle 28 and carries a pointer 11 adjacent a fixed scale 10. A rack 14 is secured to the carriage and is engaged by a spring-controlled roller 19 to justify the carriage in its several positions. The plate 8 carrying type for printing the workman's name and number and the plate 9 for printing a week-end date are inserted in guides 7. These plates are provided with slides in which the necessary type can readily be set-up. If the same record card is used for two weeks, to prevent the second week-end date being printed over the first week-end date, a shaft 36 is turned by a lever 37 through 180‹, the shaft having a cam engaging a projection 34 on the week-end date plate 9, the plate thus being moved into a position above a different column on the card. The imprint from the time wheels is obtained by depressing a lever 39 and that from the inserted plates by a lever 391. The depression of the lever 39<1> rocks anticlockwise a shaft 46 connected by an arm 47, link 48 and pin-and-slot 50 to a cam 51 having a hlunp 58 which rocks upwards a frame 53 carrying three printing hammers 54, 55, 56 for cooperation with the name plate and the two positions of the date plate. The depression of the lever 39 rocks anticlockwise a shaft 45, Fig. 3a, to pull to the left a link 64 having a roller 65 which is thus pulled over the corner of an arm 66 and thereby releases the hammer A to the action of a spring 67 pulling on a fork 69 engaging a pin 71 on the hammer.

Abstract: 1439627 Light conducting elements NIPPON SELFOC CO Ltd 17 Oct 1973 [23 Oct 1972] 48438/73 Heading C3P A synthetic resin light conducting element whose refractive index changes progressively from the surface of the element inwards is prepared by (1) prepolymerizing an ethylenically unsaturated monomer A which can form a crosslinked transparent polymer by a polymerization reaction, the polymerization being terminated when from 2 to 80% by weight of the prepolymer is still solvent-soluble; (2) shaping the prepolymer; (3) contacting at least part of the surface of the resulting shaped article with. a monomer B which forms a transparent polymer having a refractive index different from that of the polymer formed from monomer A, so as to cause the monomer B to diffuse into the article through its surface and to set up a decreasing concentration gradient of monomer B (or of a polymeric product thereof) within the article; and (4) either subsequent to step (3) or concurrently therewith, polymerizing the monomer B in the article and completing the polymerization of the prepolymer of monomer A. The prepolymer may be shaped into the form of a fibre, rod, sheet or hollow cylinder. The contact time may be such that the monomer B diffuses to the centre of the shaped article and gives rise to a concentration gradient such that the element finally obtained has a lens action and a refractive index which either decreases or increases from the axis of the element to its surface at a rate approximately proportional to the square of the radial distance from the axis. In the examples diallyl phthalate, diallyl isophthalate, diethylene glycol bisallyl carbonate and vinyl benzoate are prepolymerized in the form of rods in the presence of benzoyl peroxide and a linear polymer of diallyl phthalate. The rods are immersed in methyl methacrylate, methyl acrylate, styrene and butyl methacrylate containing benzoyl peroxide and azoisobutyronitrile and heated to cause polymerization and the formation of the elements.

Abstract: 1,248,427. Cutting and stacking bricks. H. LINGL. 17 Oct., 1968, No. 49330/68. Heading B5A. [Also in Division B8] An extruded length of brick clay is transported by continuously driven endless belts 2 and 3, the latter whereof is driven at a faster rate, past a wire cutter 4 which cuts it into blocks which then pass on to an intermittently operated conveyer 6 for an end stop 11 thereon to be engaged by a block at a position 7 to halt the conveyer 6. Each block is then cut into individual bricks by successive displacement, by a delivery slide 8, through a vertical wire cutter 10, the displacement therethrough on to an intermittently operated conveyer 15 being completed by a successively displaced block. Notching rollers and knives, respectively above and upstream of cutter 10, and on the face of the slide 8, prevent cutting flash. The bricks pushed on to the belt 15 are thereby spaced apart into groups, each of three contacting rows. Alternate groups of bricks are gripped between pneumatically actuated end plates of a device 23 which is pivoted in a vertical plane about an axis 22, which is vertically displaceable both to permit a first group to pass beneath the device 23 and to raise the gripped next group of bricks so that these are stacked on top of the first group in face to face relationship after rotation through 180 degrees. Two adjacent stacks of bricks are then gripped by a device 29 provided with displaceable grippers 30, 32 by which each stack is clamped against an intermediate plate 31. The device 29 transfers the two gripped stacks on to a kiln truck by motion longitudinally of the belt 15, and rotation 37 of device 29 through 90 degrees about a vertical axis permits a relative 90 degrees orientation of successive transferred stacks 34, 35 on the truck 33.
