Title: Improvements in or relating to cigarette cartons or like containers
IPC: B65D85/10
Filed: 1926-10-28
Abstract: 289,492. Molins, W. E. Oct. 28, 1926. Boxes formed from special blanks; fit'tings, internal; contents, facilitating access to.-A carton for cigarettes &c. comprises two U-shaped block-ended pockets 1 each formed to hold a single row of cigarettes with the axes thereof disposed parallel to the open end of the pocket and a flap 2 hingedly connecting the pockets so as to permit them to be opened out into line with the open ends 3 of the pockets directed towards one another and to extend automatically across such ends to form the sole closure therefor when one pocket is :folded upon the other; in order to render the cigarettes easy of access each pocket has a slot 4 extending at right angles to the axes of the cigarettes and located in that broad side 5 of the pocket which bears against the other pocket when the carton is closed. As shown the edges of the slots 4 are scalloped so that each scallop 18 partly encircles a cigarette with its free end depressed into the space between adjacent cigarettes so as to retain the cigarettes in position; one or both edges of each slot may be scalloped or portions of the pocket on either side of the slot 4 may be slit to form tongues which are depressed to lie in the space between adjacent cigarettes. The depth of the sides of each pocket may be made less than the diameter of a cigarette so that the sides grip lightly the ends of the cigarettes and prevent unintentional displacement thereof. The carton may be formed from a single blank or from a pair of blanks, and the material cut away to form the slot may be left attached to the base thereof and the tag thus formed folded around the block end of the pocket to extend along the plain side thereof; the cigarettes lie on' the tag and after all the cigarettes except one have been taken the last one may be easily removed by pulling the tag in the direction of the open end of the pocket; the end of the tag may be bent upwards to extend between the third and fourth cigarette in the pocket.

Title: Improvements in or relating to arrangements for stabilising electron current in electron discharge devices
Inventor: ROGERS DOUGLAS CECIL
IPC: G05F1/52
Filed: 1949-10-21
Abstract: 663,256. Automatic current control systems. STANDARD TELEPHONES AND CABLES, Ltd. Oct. 21, 1949, No. 27085/49. Class 38 (iv). [Also in Group XL (c)]. In a system for stabilizing the cathode current of an electron discharge device, the cathode current controls the potential of a control electrode of the device through a voltage amplifier, and a warning is given when the potential of the control electrode reaches a predetermined value. To maintain constant the beam current of a travelling wave amplifier tube 1 supplied with H.T. from a D.C. source 11, 12, the volt-drop across a resistor 17 in the cathode circuit is applied, in opposition with a constant reference potential, obtained across a gas-filled tube 16 from source 11, 12, to the grid-cathode circuit of a thermionic valve 19, anode current variations of which, by controlling the volt-drop in a resistor 18 adjust the potential of first anode 4 of tube 1 in the appropriate sense to maintain the beam current constant. When emission has fallen, due to age, to such an extent that the anode current of valve 19 is below a predetermined value, a relay 20 closes contacts 22 to light an indicator lamp 23 or give an audible warning, and closes contacts 21 to short-circuit a resistor 9 in the heater circuit thereby slightly increasing heater current until the tube can be replaced. Relay 20 is reset manually when tube 1 is replaced. Use of a neon indicator in series with the anode circuit of valve 19 instead of lamp 23 is described and application to the stabilization of electron currents of velocity modulation devices and cathode-ray tubes is referred to.

In spectroscopic apparatus for determining, for example, relative concentrations of component substances in a mixture there is compared in cyclic succession with the aid of a radiation detector, the integrated intensities of several low-absorption regions in the respective absorption spectra, these regions being selected from a continuous real-image spectrum, derived from an entrance slit by collimating and dispersive means by means of slotted masks each having a slot configuration corresponding to the characteristic lowabsorption regions of one particular component, there being reflecting means behind the mask position to return the light passing through the slots parallel to its original path for synthesis in the dispersive system and imaging on an exit aperture. In the spectroscope shown, light from the entrance slit 1 is collimated by the concave mirror 2 for passage through the dispersing prism 3, the Littrow mirror 4 returning the light with a small angular displacement to form a focussed spectrum in the median plane of a roof-mirror 5. Masks 8 A  and 8 B  are placed in the plane of the spectrum and the spectrum is moved alternately over each by rotary oscillation of the Littrow mirror about an axis 9. The selected spectral bands are returned through the optical system, with a small angular displacement, by the roof-mirror to form a slit image on an exit slit close to the entrance slit 1, having an intensity equal to the sum of the intensities of the selected spectral bands.
