Patent GB-914225-A (GB)
Title: Package sealing or labelling apparatus
IPC: B65B51/06
Filed: 1957-11-25
Abstract: 914,225. Apparatus for applying adhesive tape. GUTHRIE, G. Feb. 25, 1959 [Nov. 25, 1957; Feb. 24, 1958], Nos. 36608/57 and 5863/58. Class 73. Apparatus for applying fusible pressure - sensitive adhesive tape having a base of unplasticized polyvinylchloride or like charge-generating film to an article has a heated element 26-27 for severing the tape, tape applying means including a backing member and a support for the free end portion of the tape below the backing member so that the tape lies against the latter whilst being cut. The packages 2 advance along a conveyer 1 to contact a backing strip 13 pivoted at 12 on which tape from the reel 30 clings adhesive-side-out by virtue of the electrical charge it gains when it unwinds. The strip 13 is connected to a presser-roller 18 on arm 16 through axis 14, and link 15 so that when the leading face of the package 2 pushes the strip 13 downwards out of its way, the roller 18 is similarly lowered. A short length of the tape thus adheres to the leading face and the tape continues along the undersurfaoe of the package until the strip 13 trails it clear of the rear edge. The heated wire is carried on an insulated arm 21 freely pivoted at 12. Like the strip 13 it is depressed by the leading edge of the package to trail along the undersurface of the latter, until, passing beyond the rear edge, it rises due to the counterweight 20 so that the hot wire severs the tape. This frees the strip 13 which rises due to a counterweight 19 and causes the roller 18 to pivot up and press the free end of the cut tape on to the receding face of the package. Similar mechanism (not shown here) is provided above the conveyer path 1 to apply tape along the ends and upper surface of the package. Specification 914,226 is referred to.

Filed: 1966-08-16
Abstract: 1,198,626. Extraction of saponins and sapogenins. NATIONAL RESEARCH DEVELOPMENT CORP. 28 July, 1967 [16 Aug., 1966], No. 36711/66. Heading C2U. Sapogenin-affording vegetable materials are treated with a saturated hydrocarbon containing at least 6 carbon atoms per molecule in the presence of water (including water present in the fresh vegetable material), prior to the recovery of a saponin or sapogenin therefrom. The vegetable-material may in addition be pre-treated by incubation in an added aqueous medium, and the treatment with hydrocarbon may be concurrent with or subsequent to incubation. Degrading enzymes (e.g. cellulose or pectinase) may be used in the incubation. Sapogenins may be recovered from the treated material (from which the hydrocarbon may or may not have been removed) by direct hydrolysis thereof (e.g. with HCl) or by hydrolysis of an extract thereof in a solvent (e.g. methanol), and removal of the sapogenins from the thus obtained hydrolysate. The starting vegetable material may be a monocotyledonous material of the Dioscoreaceae, Lilaceae or Amaryllidaceae families or a dicotyledonous material of the Leguminosae, Balanitaceae or Zygophyllaceae families. Seeds of dicotyledonous materials are preferably uncomminuted (see Specification 44949/65 Serial No. 1,136,626). A preferred hydrocarbon is squalane (2,6,10,15,- 19,23 - hexamethyl - n - tetracosane). Sapogenins obtained are diosgenin and yamogenin.

Abstract: 1,023,087. Particle accelerators. UNITED STATES ATOMIC ENERGY COMMISSION. Sept. 15, 1964 [Nov. 18, 1963], No. 37546/64. Heading H1D. In a synchrotron the increase in the frequency of the R.F. accelerating field is interrupted during which stage the R.F. is switched off and then switched on again at a lower harmonic and the increasing magnetic field is held constant. The object is to limit the bandwidth necessary in accelerating heavy particles, e.g. deuterous, alpha particles or Li<SP>6</SP>,B<SP>10</SP>or C<SP>12</SP> nuclei, to high energies. In the interval when the R.F. field is switched off and the magnetic field held constant the particles are debunched and stored in a circular orbit without increase in velocity. Initially the R.F. may be tuned to the 24th harmonic of the orbital frequency of the particles and after interruption returned to the 12th harmonic. The acclerating cavities are ferrite loaded and the R.F. oscillator is locked on to the proper frequency by means of beam probes for detecting the orbital frequency of the particle bunches. Probes also control the magnetic field. The synchrotron has alternating-gradient focusing and the particles are injected from a standing wave linear accelerator.
