Title: Hypodermic syringe for injecting fluids into the body or for taking them therefrom
IPC: A61M5/31
Filed: 1924-11-14
Abstract: 236,095. Meyer, F. July 23, 1924, [Convention date]. Syringes. - A surgical syringe comprises a container closed by an elastic stopper and a cannula which passes through the stopper and extends into the container, the arrangement being such that the cannula is opened to the container by moving the stopper. The syringe may be used for injecting fluids into the body, in which case the container holds the injection fluid under pressure, or for withdrawing matter from the body, in which case the container is vacuous. Fig. 1 shows a syringe for injecting fluids into an existing opening in the body. The inner end of the cannula K is bent, as shown, and normally bears against an extension of the elastic stopper P, the syringe being put into action by moving the stopper, as shown by the dotted lines. For hypodermic injection and like purposes a needle is attached to the cannula K. Fig. III. shows a modified construction in which the cannula K is formed with an enlargement H into which blood or other liquid rises when the needle N is inserted into the body, this arrangement serving to indicate the nature of the organ pierced by the needle. In a further modification the cannula K is extended so that the chamber H lies outside the container. Fig. VI. shows another modification in which. the cannula is normally sealed, and, when required for use, is broken at a weakened point by moving the stopper P so that the inner end of the cannula is pressed against the wall of the container. In this construction the cannula may be so shaped that, after breaking, the portion passing through the stopper can still be opened in the same way as the cannula shown in Fig. I. The syringes are prepared for use by piercing the elastic stopper with a hollow needle which is connected to a, source of fluid under pressure or to a suction device. When the syringe has been filled or evacuated, the needle is withdrawn, and the stopper, by virtue of its elasticity, automatically closes.

Filed: 1975-07-01
Abstract: 1486968 Two-part couplings A G HERNANDEZ 1 July 1975 [2 July 1974] 27661/75 Heading H2E  A socket has a switch 18 which isolates at least one socket contact 20 from the mains supply when there is no mating plug connected, and a shutter 9 mechanically interlocked with the switch and covering the socket contacts, such that the switch cannot be actuated to connect said at least one contact 20 to the supply until after the shutter has been moved clear of the contacts. The socket comprises a body piece 8 with apertures 3<SP>1</SP> through which plug pins enter to connect with socket contacts. The apertures are shown closed by wedge-shape extensions 13, 14 of the shutter 9 which is slidable upwardly against a spring 10 and within a recess (15, Fig. 4, not shown) in the piece 8. The shutter has a recess 22 into which engages a projection 23 of a push-button 5 mounted in a cavity 17 for movement at right angles to that of the shutter against a resilient portion 25 of the switch; however the button cannot move while the projection 23 is engaged in the recess 22. The shutter is able to turn slightly, Fig. 6, not shown, within the recess (15); thus if there is an attempt to raise the shutter by application of an object through one aperture 3<SP>1</SP>, the shutter will turn and not release the push-button. Insertion of a plug raises the shutter clearing the recess 22 from the projection 23, and then depresses the pushbutton causing the portion 25 to move switch contact 26 into connection with switch contact 21 and thus energize the socket contact 20.

Title: Sound attenuation
IPC: B64F1/26
Filed: 1958-09-01
Abstract: 905,601. Building units. WOHLBERG, G. Sept. 1, 1958, No. 28007/58. Class 87 (1). [Also in Group XXVII] A sound-attenuating self-supporting discrete structural unit, Fig. 2, has at least one interior chamber 102, imperforate sides 106 and a rectangular sound-attenuating face having formed therein for each chamber a single substantially acoustically unobstructed opening 112 extending substantially across the entire width of the face but not completely across its length, e.g. over from one-quarter to one-half thereof, and forming the only access from the chamber to an exterior sound field. As shown, the opening 102, and perforate or imperforate decks 110 which may have upturned edges 114 and which support glass or stainless steel wool soundabsorbent pads 116, are covered by a permanently secured or screwed-down perforated plate 118, preferably having at least 10% open area. The plate 118 may be dispensed with, the pads 116 being retained by staples, adhesive or wire mesh. The unit, including the members 110, 118, may be of sheet-metal, plywood or " plastic." Externally identical units of the same or differing internal form are used to line room walls. Examples are given of units divided by transverse partitions into two or three chambers of equal or unequal volume. The units may have lugs or flanges to connect them together or to supporting framework, or, if of metal, may be welded together along edge portions. They may form or line one, two opposed or adjacent, three or all four sides of a square or a rectangular section gas passage, or passages in parallel, the units being arranged longitudinally of the passage or passages in a row or side-by-side rows. Where two like units are arranged back-to-back they may be constructed as a single double-faced unit with a central longitudinal partition. The manner of arranging internally different units in a passage to suppress resonance and attain desired attenuation effects is explained in detail, and graphs showing the variation of sound attenuation with frequency are given. In Fig. 36, slides 218 can vary the size of the opening 112, and in Fig. 40 there is an opening 112 at each end of the unit which is divided by a partition 246 into corresponding chambers.
