Title: Improvements in or relating to appliances for drawing liquids from containers
IPC: A61M5/162
Filed: 1962-10-29
Abstract: 977,039. Transfusion apparatus. B. BRAUN, and O. BRAUN, [trading as B. BRAUN]. Oct. 29, 1962 [April 12, 1962], No. 40845/62. Heading A5R. A sight-feed glass for transfusion purposes has adjustable means in the outlet for controlling the rate of flow. The container 5 receives liquid through an inlet connection 3 and the upper end of this is pointed or fitted with a hollow needle 19 to perforate the closure member of a liquid or blood storage container. The flexible outlet tube is fitted to the lower end 17 of a centrally bored member 12 which fits inside a tubular member 10 in which it is axially adjustable by a threaded engagement 15. Liquid normally rises approximately halfway up the container 5 and then passes through apertures 8 in the wall of the member 10 and so out through the bore of the member 12. However, advancing the latter upwards, by the screw adjustment, causes its upper end to obturate the apertures 8 to an increasing extent, to reduce the rate of flow, until it ultimately seats against the shoulder at the top of the tubular member 10 and the flow ceases completely. In the embodiment shown an air inlet filter 21 is fitted to a flexible, bulbous chamber 20 from which air passes through a tube to apertures 2. This chamber 20 may be squeezed to assist in starting the fluid flowing and it also serves as a reservoir if liquid tends to flow back through the air inlet and so prevents the filter 21 becoming saturated. The upper part 6 of the tubular member 10 encloses a ball float 7 so that if the fluid container becomes exhausted the ball 7 will fall and close the upper end of the tube 17, so as to prevent the possibility of air being carried through the outlet tubing to the patient.

Abstract: 1,271,491. War rocket. DEFENCE, SECRETARY OF STATE FOR. 19 Sept., 1967 [19 Sept., 1966], No. 41813/66. Heading F3C. A shoe for use with a rocket projectile when fired from a trough launcher is shaped for mounting in the launcher trough at the rear end of the projectile in engagement with a rearwardly facing part of the latter, at least a portion of the shoe being of such a cross-section as to obturate, when so mounted, the rear end of the channel between the projectile and the surface of the trough. As shown, the shoe 7 has a body 8 of V-shaped cross-section to fit the contours of the trough 3 in the launcher 1. The main part of the body 8 is made of a lightweight plastics material, e.g. expanded polystyrene, and extends from the rear of the projectile to the forward edge of the lowermost fin 6a which is accommodated in a deep groove 9 in the shoe 7. An aluminium plate 10, contoured to fit against the walls of the trough 3 and the underside of the projectile, is bonded to the rear face of the body 8. In order to provide a more effective seal, the plate 10 has a sheet 11 of flexible, heat resistant material attached to its rear surface, which sheet overlaps the plate 10 somewhat to provide a flexible sealing lip around the walls of the trough 3. It is not necessary to attach the shoe 7 to the projectile during launch. In an alternative construction, the body 8 is hollow and formed of sheet metal. The above arrangement prevents, or at least considerably reduces, the ingress of expanding propellant gas into that part of the trough beneath the projectile thus reducing the tendency to lift the projectile off the launcher rails during launching.

Abstract: 1,199,160. Crying and pouting doll. DE LUXE TOPPER CORP. 20 Sept., 1967 [6 Feb., 1967], No. 42803/67. Heading A6S. A doll comprises a reservoir 54 for a tearsimulating liquid, conduits 76 extending therefrom to eye-holes 78, and an appendage whose movement actuates means for selectively permitting or preventing liquid flow from the reservoir. As shown arms 22, a drum 31 and a disc 32 are rotatable on a shaft 26: the arm's are normally urged towards the raised position, in which the tear-producing means are inoperable (fig. 4 not shown), by a spring 34. The arms may be lowered against the action of the spring to the position of fig. 6, which is maintained by a latch 41 engaging a slot 42 in the drum 31, and which is released by depressing a button 47, connected by a yoke 49 to the latch 41. In the lowered position the tear-producing means is actuated, liquid flowing to conduit 76 through a valve 73. In the arms raised position this is prevented by the action of a spring 83 on a movable valve disc 81. On lowering arm 22, a stud 94 on the drum 31 moves downwards; this motion is transmitted via wire links 92, 90 to a lever 87 pivoted on the reservoir cover 55, thus raising the valve disc 81. Simultaneously a plug 98 is pushed down against the force of a spring 101 to allow air to enter the reservoir. The arms are also used to change the facial expression of the doll. For this purpose a pivoted jaw. 103 and a fixed jaw 102 grasp a resilient pouch 112 integral with the resilient lips 113 (forming a smile in the armsraised position; fig. 5, not shown). As the arm 22 is raised, the motion of the link 92 is transmitted to the pivoted jaw 103. The pressure exerted on pouch 112 is such that lips 113 take on a pouting expression ('fig. 7, not shown). The doll may be in the form of an animal whose tail may constitute the appendage for controlling crying and pouting.
