Title: Apparatus for wrapping an article in thermoplastic sheet material
Inventor: JR HERBERT RUMSEY
IPC: B65B61/10
Filed: 1955-12-05
Abstract: 780,690. Cutting webs; seaming. GLAZWRAP PACKING CO. Dec. 5, 1955, No. 34803/55. Classes 31 (1) and 42 (1). [Also in Group XVII] A wrapping apparatus (see Group XVII) in which articles are hand wrapped in thermoplastic sheet drawn from a roll, has a heated wire or blade for severing the sheet and a displaceable bar, over which the sheet passes, which draws the severed edge of the sheet away from the wire or bar. In one embodiment, two webs for wrapping round a cylindrical article 75 are drawn from rolls 19, 20 over a guide bar 28 and beneath a displaceable bar 30. The article is rolled in the superposed webs on a platform 16 and is then placed on a platform 17, the webs being tensioned by reason of brake shoes 32 operating on their supporting axles, and the tension raising the rod 30. The platform 17 is capable of tilting about a pivot 44 to bring the webs into contact with a heated wire 60, and as the wire severs them, the rod 30 drops to pull them clear. A stop 51 is adjustable on the platform 17 to vary the distance between the package and the platform edge 52. In other embodiments (not shown) in which the platform 17 does not tilt, the wire 60 may extend above the platform level so that placing the package on the platform causes severing, or the wire may be raisable by treadle or other means operating toggles causing upward sliding of wire end supports. The platform 16 may be dispensed with. In a further embodiment, Fig. 14, web 122 from a single roll is led under a braking roller 120 and over a bar 123 carried on arms pivoted at 125 and biased upwardly by springs, or, as shown, weights. When the partially wrapped article, which may be as in Fig. 19, is placed on a tilting platform 113, a heated blade 139 severs the web and permits the bar 123 to pull the severed edge clear. A row of heated studs 144 acts through an aperture 133 to secure foldedover ends 154 of the package. A continuous sealing bar may be provided in lieu of the studs. An adjustable ramp 147 facilitates wrapping.

Title: Improvements in or relating to electron accelerating apparatus
IPC: H05H13/00
Filed: 1936-12-19
Abstract: 487,778. R÷ntgen-ray tubes ; cathoderay tubes. KLEMPERER, O. Dec. 19, 1936, No. 34935. [Class 39 (i)] High velocity is imparted to electrons for generating X-rays or for use in cathode-ray tubes by causing them to take orbital paths within a two-part housing to which an oscillating field is applied so as to produce a repeated acceleration as is described with regard to ions in U.S.A. Specification 1,948,384. The electrons are emitted from a cathode F between the two parts A, B of a semicircular casing which is connected to a source O of alternating voltage. A magnetic field is applied transversely to the casing, causing the electrons to take orbital paths, and the dimensions and field strengths are so proportioned that the potentials of the portions A and B change as the electron passes from one to the other. The radius of the orbit increases as shown and the target T is placed near the outer wall of the casing. In order to increase the period of the source O the electrons may be caused to travel in trochoidal paths P1, P3, P4 as shown in Fig. 4. This is effected by varying the magnetic field in a radial direction.

Abstract: 1399501 Blood oxygenators R A DEWALL 27 July 1972 [3 Aug 1971] 35213/72 Heading A5R [Also in Division F2] A perfusion safety valve, which is designed for use in blood oxygenating systems wherein it is disposed downstream of an oxygenator and upstream of a pump (Fig. 1, not shown) comprises an elongated relatively rigid tube 18 perforated at 20, an outer membrane wall 26 outside the tube, and an inner membrane wall 24 within the tube, the two membrane walls being sealed to the ends of the tube and defining a closed space 28 therebetween. Space 28 contains a saline solution. Tube extensions 30 are barbed as at 34 to facilitate their connection to the lines of the system. The inner membrane 24 is made of any suitable blood compatible material such as a silicone rubber or a polyvinyl plastics material. In use, as long as the head of blood in the oxygenator reservoir exceeds a predetermined level, the pressure of the same will maintain the inner membrane 24 in the position shown, that is with the membrane abutting the inner wall of tube 18. If, however, the blood level fall below the predetermined level, then this together with the slight vacuum created by the pump will result in the atmospheric pressure applied to the outer membrane 26 collapsing the same and so driving the saline solution within space 28 through the perforations 20 to force the inner membrane to collapse and thus seal upon itself, (Figs. 3 and 5, not shown). Accordingly the valve precludes any possibility of air embolism.
