Title: Chest aspiration - abdominal paracentesis cannula
Inventor: BRYANT BRUCE MICHAEL
IPC: A61M1/00
Filed: 1983-01-14
Abstract: This device is designed to facilitate the aspiration of pathological fluid from the chest and abdominal cavities via a closed system. The needle sleeve protruding from the end of cannula (A) is inserted through the skin and when in the required position the needle is withdrawn into the cannula by means of the screw (D) within the housing (B) the whole apparatus then being secured to the skin by means of the plastic coating (J) on the circular flange (H). With flow regulator (G) closed and tap (N) opened the concertina bag is evacuated, tap (N) is then closed and the hole (O) is located on the hook (T) to create negative pressure within the bag. Flow regulator (G) is then opened and fluid allowed to run into the bag from the body cavity in the required quantity. After drainage drugs may be introduced via injection port (F) into the body cavity once flow regulator (G) has been closed the apparatus is then withdrawn from the chest or abdominal cavity. <IMAGE>

Title: Clothes line arrangement and cover therefor
Inventor: MCDAID JAMES GERARD
IPC: D06F57/02
Filed: 1983-01-18
Abstract: A clothes line arrangement comprises two vertical posts 1 supported in the ground 2 and each post has pivotally attached to a point intermediately along its length two arms 3, each of which may swing in a vertical plane through the post upwardly and downwardly. One line is provided on each side of the posts. Each line 4 comprises a horizontal run 8 that passes through eyes 7 at the outer ends of the arms 3, then extends laterally to pass through eyes 6 at the upper ends of the posts, and then downwardly along the posts to handles 5, the handles 5 being common to both lines 4. The handles are secured to the post by means of lower fixing means 9 and may be disengaged therefrom and transferred to upper fixing means 10. This allows the lines to slacken with the result that the arms 3 will drop to a lower position by virtue of the lines running through the eyes 6 and 7 to allow clothes to be hung on the lines. A cover for the clothes line arrangement runs along horizontal guide lines 84, 85 pulled taut between the posts, and is formed from discrete segments or a continuous length folded in convoluted or concertina style, draw lines 81 enabling the cover to be extended along the guide lines or drawn back and telescoped or folded against one post. <IMAGE>

Title: Resilient hose couplings
Inventor: TURNER DAVID LILLEY
IPC: F16L33/16
Filed: 1983-05-11
Abstract: To improve the male-and-female joint of the end of a pressurised hose over a spigot, the inner wall of the hose is formed in such a way as to present an axially-facing surface close to the end, so that the action of the pressure upon that surface tends to cause the inner diameter of the hose end to contract upon the spigot. The surface may for instance be formed by grooving 5a or splitting 11 the inner wall of the hose, or by forming a step in it close to the end 15, Fig. 4, and if the hose contains longitudinal reinforcing members the normal alignment of these must if necessary be displaced to allow clearance for the surface. <IMAGE>

Title: Output torque dependent throttle control system for internal combustion engine
Inventor: HOSAKA AKIO
IPC: F02D9/02
Filed: 1985-02-07
Abstract: An accelerator produces a signal 4110 representative of a required or demanded output torque 4122-5. Actual output torque 4130 is monitored by means of a torque sensor. The actual torque is compared with the output torque demand derived from the accelerator signal to obtain the difference therebetween 4140. Feedback control is performed on the basis of the calculated difference so as to control the throttle valve angular position to increase or decrease the actual output torque toward the torque demand value. The mode selection 4122 determines the relationship to be applied in relating the signal 4110 to the demanded torque. <IMAGE>
