Abstract: 1,081,970. Flip-top carton. BROWN CO. June 15, 1966 [June 16, 1965], No. 26738/66. Heading B8P. An integral blank, for erection into a " flip top " carton has side flaps 7, Fig. 1, with recesses 19, to allow adhesive contact between side panel 5, and outer side flap 6 on erection, flap 6 then overlying flap 7. The hinged lid 4 is adhesively connected to the front wall 2, of the carton along edge portion 17, and a similar connection is effected between tabs 10, and side flap 7. The lid is opened by removing the tear strip 15 and breaking fracture lines 11. Recess 19 may be of rectangular contour, and recess 20 is formed to accommodate an adjacent inverted blank. Instead of the tearstrip there may be a severance line (21), Fig. 6, connecting the sealed lid edge to the wall 2, the sealing adhesive being applied in zones to the wall around which there may be scores (24), Fig. 7, to prevent the wall from being torn when the edge is removed. The carton may be made from paperboard coated with plastics or wax and an adhesive which may be heat sealable is carried on the carton blank. As an alternative to tab 10 there may be a serrated area (23), Fig. 7, along the side of the lid 9, which overlies flaps 6, 7, and is adhered to them.

Abstract: 206,829. Akt.-Ges. Brown, Boveri, et Cie. Nov. 8, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Vacuum tubes; low-pressure metallic-vapour apparatus.-In order to prevent back ignition the surface of the anode of a mercury-vapour rectifier or other discharge device is provided with recesses or projections of such shape that, at as many points as possible, lines drawn at right angles to the surface meet the anode surface again at a certain distance; ionization of the gas between the anode and cathode is thus reduced.

Title: Improvements in or relating to air-pressure-operated controllers
IPC: G05B11/50
Filed: 1962-07-13
Abstract: 1,020,251. Analogue computers. HONEYWELL Inc. July 13, 1962 [July 17, 1961], No. 27062/62. Heading G3P. An air-pressure-operated controller comprises two air tight casings 21, 21A, Fig. 1 (not shown) which are divided into two variable volume compartments by capsules 24, 24A. Rods 39, 39A are respectively connected to the capsules 24, 24A and are pivotally mounted on the casings. A drive rod 51 is pivotally connected at its ends to the ends of the rods 39, 39A and actuates a flapper 73 controlling the leakage from a nozzle 67. The nozzle back pressure acts on a diaphragm 85 of a relay valve 82 to provide an output pressure in line 111. A line 93 provides a set signal pressure to the casing 21A and a pressure proportional to the measured process signal is fed to the capsule 24A although this arrangement may be reversed by a changeover valve 94. The pressure fed to the capsule 24A may be proportional to the process signal or may be modified by a differential controller 99. The output pressure in line 111 is fed to the capsule 24 to provide a feedback and may also be fed through a valve 112 to the casing 21 to provide an integral control. The position of the flapper-assembly relative to the rod 51 may be adjusted to vary the gain. The speed of action of the integral and derivative controls may be varied by opening volumes 127, 110 to the pressure lines 124, 107.

Title: Improvements in fluid bearings
IPC: F16C32/06
Filed: 1946-09-11
Abstract: 616,748. Bearings. CHAMPNEY, L., CAMERON, A., STUDDERT, M. E. P., and LEES, D. M. Sept. 11, 1946; No. 27297. [Class 12 (i)] In a fluid bearing supplied with gas under pressure through at least two passages opening radially into the space between the bearing surfaces, the passages are arranged symmetrically about the vertical axis of the bearing and the total cross-sectional area of the passages below a line drawn horizontally through the centre of the bearing is greater than that of any passages above such a line. As shown, a journal a has a central bore b to supply air under pressure via radial passages c to the space between the journal a and a bearing bush d. The ends of the radial passages c opening between the bearing surfaces are radiused to overcome eddy currents of pressure air. In an alternative arrangement the pressure air may be supplied between the bearing surfaces via an annular groove in the bearing housing communicating with radial passages in the bearing bush. Case-hardened steel journals ground to a " mirror " finish working inside diamond-turned hard brass bushes may be used, the radial clearance between the bearing surfaces being from 0.0005 to 0.001 inch. Fig. 7 shows a gimbal ring mounting wherein pressure air is supplied to one end of a journal. a by means of a non-contact gland comprising an annular disc i axially opposed to the journal end. Pressure air escaping between the disc i and the journal end causes an axial thrust on the journal which may be opposed at the other end of the gimbal axis by a single ball contact or an air-lubricated footstep bearing. The pressure air is conveyed from one journal to the other by a pipe carried on the gimbal ring and connecting transfer passages j. Fig. 8 shows an alternative form of bearing in which the journal a and bush d have conical bearing surfaces so that the effect of air from the passages c has an axial component providing end thrust for axial location.

A means for attaching rails to road forms comprises a rail-holding component provided with a shank portion which non-rotatably engages rectangular or other non-circular apertures formed in end-plates and/or other rail supporting parts of the road form and a laterally extending head portion provided on the rail-holding component engages the rail base flange to prevent rock or tilt of the rail by the wedging or locking of the shank within the aperture. As shown, claw members h are vertically slidably mounted in apertures f provided in a flange e formed on the end wall c or some other portion of a road-form so that when the rail g is tilted the rail flange g<SP>1</SP> tends to tilt the claws h which become firmly wedged within the apertures f, thus holding the rail in position. The claws h may be prevented from complete withdrawal from the apertures f by a split-pin and a washer k mounted on a cylindrical portion of the claw h which portion allows the claw h to be lifted and rotated to permit removal of the rail g. The claw members h may be located between spaced stops, welded or otherwise secured to the rail flange, to prevent creep. Specifications 699,926, [Group X1 and 762,382 are referred to.

In a Miller-transitron sawtooth generator having capacitive coupling between screen and suppressor, the frequency is controlled by variation of a negative voltage 16 applied to the suppressor. The circuit may be synchronized by negative pulses 15 5 applied to the suppressor, screen or anode. The amplitude of the sawtooth output at the anode is independent of frequency. Reference is also made to a circuit in which capacitor 4 is connected between the fifth and first grids of a heptode, synchronizing pulses being applied to the fourth grid, and the anode being connected to a phase discriminator to which the synchronizing pulses are also applied. The direct voltage produced by this discriminator is then fed to the fourth grid as frequency control. The invontion may be applied to a generation of frame sweep for a television receiver. Reference is also made to known circuits in which the frequency is controlled by variation of anode or screen voltages.
