Title: Improvements in or relating to caps or stoppers for bottles and jars
IPC: B65D51/20
Filed: 1920-03-15
Abstract: 150,640. Parker, C. C. March 15, 1920. Capsule closures. - A bottle or jar closure or cap comprises an outer member 5 to cover the lip of the vessel, a hollow plugmember 4 in the form of a flanged paper disk to seat in an annular recess 2 at the top of the vessel, and a reinforcing or sealing-member 8. The members 4, 5, 8 are secured together by a waterproof paste, and the members 4, 5 are cut through by an are or U-shaped cut 7 to form a lifting-tab 13. Transverse and preferably curved cuts 11 are formed just beyond the ends 10 of the slit 7 in the member 4 to distribute the stress applied to the tab and prevent tearing. The tab is raised at the base 14 and supported by a protuberance 15 on the member 8. The lower edge of the plug member 4 is doubled back on itself, and the extreme edge of the flange 19 is turned sharply outwards at 20 so that when the member is inserted in the recess 2, the edge is turned upwards.

Title: Fluorometric system and method for the detection of biologically derived substances
IPC: G01N33/52
Filed: 1975-02-26
Abstract: 1506017 Fluorometric sample detection INTERNATIONAL DIAGNOSTIC TECHNOLOGY Inc 26 Feb 1975 [4 March 1974] 8059/75 Headings G1A and G1B A fluorometric system comprising means for exciting and means for receiving fluorescent light and a body 10 with an elongate handle joined to a portion having a continuous surface carrying a reagent 11 selectively reactive with the biologically derived substance 14 to be detected. Sample 11 may be an antigen and substance 14 an antibody or vice versa. The body may have two samples one of which is a standard, the intensity of fluorescence being proportional to the quantity of antigen. Alternatively the samples may comprise different antigens (or antibodies), the labels being different fluorescent substances. The sample areas may comprise bands. The fluorometric system may comprise such a body and a monochromatic light source between 0À2 and 1À0Ám and means, as light guide 24, to convey the light to the body of a detector of fluorescence. Nylon sphere 10 of diameter 10mm bears a dried antibody film 11. Glass cuvette is racked for 5 mins with added serum 13 so that antigen 14 present binds to 11. The cuvette is rinsed, incubated with solution of antibody 23 tagged with sodium fluorescein isothyocyanate and resinsed. Ultraviolet light is then passed through filter 28 of 460 nm. Fluorescence from antibody 23 reaches a photo-multiplier via a filter and a fibre optic cable. The electric signal is filtered, rectified, linearized, amplified, converted to digital and displayed on a digital meter calibrated in titre. Two fibre optic cables each with filters and a chopper wheel may supply the photo-multiplier with fluorescence alternatively from the two bands. Two photomultipliers may be used without a chopper. The substrate may be paddle shaped, a cube or other polyhedron with a handle and with a different sample on each of the vertical faces. The fluorometer may have a filter wheel with a selected fluorescence wavelength for each face. A modified fluorometer may have a single fibre optic cable 86 dividing into two or into four as in Fig. 9. Substrate 87 has fluorescent sample 88. Branches 81, 82 transmit light from lamps 89 and 90 and branches 83 and 84 conduct the fluoroescence through lenses 91 and 92 to solid state detectors or photo-multipliers 93, 94. Surface 88 may include a plurality of randomly dispersed fluorescent samples, tagged with different exciting wavelengths and excited from a single lamp via a plurality of filters.

Abstract: 158,202. Tekniske Forsogsaktieselskab. Jan. 29, 1920, [Convention date]. Machinery, utilizing inertia to obtain movements in.-Relates to means for converting rotary motion into oscillating motion or to motion in a closed curve particularly applicable for actuating the wings of ornithopters or other flying machines. In the arrangement shown in Fig. 1, the wing F is mounted upon a hollow rib H journaled at K. A shaft W, connected by a universal joint &c. to a driving-shaft A, carries at the end a pivoted arm S at the end of which is mounted a weight O. The rotation of the weight 0 produces an oscillation of the wing F. By employing two weights rotating in opposite directions and adjustable in relative velocities and positions, the end of the wing can be made to trace a lemniscate or other closed curve. In the arrangement shown in Fig. 8, the ribs H are extended, the extensions operating between pairs of buffers h1-h2, h3-h4, for the purpose of determining the location of the path of oscillation. Similar buffers may be arranged at right angles to determine the motion in a plane at right angles to the paper. As shown in Fig. 9, the shaft W is driven through bevel or other gearing R, R so that the oscillation of the wing is more rapid in one direction than in the other.

Abstract: 647,286. Machinery safety devices. BURN & CO., Ltd., J., and SKEATES, A. E. G. March 23, 1948, No. 8536. [Class 80(iv)] A book-sewing machine has a guard rail 22 carried by a pair of arms 24 and connected by links 30, 34, 36, 38 to a lever 40, pivoted at 42, which operates a clutch 44. The arms 24 are pivoted to members 26 which slide along the guides 27 for the signature arm 12 which carries the book sheets 14. A pedal 54 is depressed against the action of a spring 62 to engage the clutch and start the machine. Should the operator's hand travel with the signature arm along the path 16 it will lift the rail 22, move the link 38 and disengage a notch in it from a pin 48 on an arm 50 connected to the pedal 54. The spring 62 then disengages the clutch 44 and the pedal 54 drops, thereby applying a brake band 58 to a flywheel 60. A hinged guard 65 is also provided to prevent interference with the sewing appliances 10 while the machine is running. The guard 65 is rigid with a cam 74 which coacts with an arm 70 connected by a link 72 to the link 30. The arm 70 may be used normally to stop the machine. The Provisional Specification states that where the machine is driven by an electric motor lifting of the rail 22 may open a mercury switch carried thereby to control the motor energizing circuit. Also the height of the guard rail may be adjusted by altering the length of the rod 36.
