Title: Apparatus for controlling exhaled breath
IPC: A41D13/11
Filed: 1980-04-28
Abstract: Apparatus for controlling exhaled breath, particularly for use by surgeons, comprises a face shield 10 supported in a position to cover only a part of the face of a user, adjacent the nose and mouth, whereby the interior of the face shield will, in use, receive exhaled breath from the nose and mouth of the user. A gap or aperture is provided for the ingress of ambient air into the interior of the shield, and suction conduits 13, 22 lead from outlets 12 in the shield to a suction pump, for example a small battery- operated suction pump 14, carried on a belt 15 worn by the user. In use, the suction pump 14 withdraws exhalation from the interior of the shield 10, through the outlets 12 and conduits 13, 22, and expels the exhalation into the ambient atmosphere at a desired location, for example from a downwardly facing exhaust aperture 16 on the suction pump 14. <IMAGE>

Patent GB-813391-A (GB)
Abstract: 813,391. Electrolytic capacitors. GENERAL ELECTRIC CO. Dec. 8, 1955 [Dec. 15, 1954], No. 35272/55. Drawings to Specification. Class 37. The silver cathode of an electrolytic capacitor is subjected to a prolonged treatment with hot concentrated sulphuric acid prior to assembly. As a result a dark film is formed on the surface of the cathode, the film apparently having lowresistance properties whereby the reduction in overall capacitance normally occasioned by the capacitance between the cathode and electrolyte is obviated. The anode material is preferably tantalum, niobium, a tantalam-niobium alloy, zirconium or titanium. The electrolyte may consist of lithium chloride or a mixture of ethylene glycol, water and ammonium succinate or borate. In the preferred embodiment the cathode forms an outer casing within which is disposed the anode which may be of cylindrical or spiral form.

Patent GB-820617-A (GB)
Abstract: 820,617. Photographing rapidly moving objects. MINISTER OF SUPPLY. Nov. 9, 1956 [Aug. 9, 1955], No. 22898/55. Classes 97(1) and 98(1) A mirror is rotatable in front of a photographic camera so as to keep the reflected image of a moving body in the field of view of the camera. The optical axis of the camera may coincide with the axis of rotation of a mirror mounted at 45 degrees'to this axis. Alternatively, as shown, the optical axis of a high speed kinematographic camera is perpendicular to the axis of rotation of mirror 2. A projectile arriving at P<SP>1</SP>energizes means for rotating the mirror so that when the reflected optical axis has rotated from P to A, it is moving at the same angular velocity about spindle 23 as is the projectile which simultaneously reaches A. The projectile is photographed between A and B. The mirror may be rotated at a constant angular velocity from a prime mover through a magnetic clutch (Figs. 1 and 2, not shown). A high initial current brings the clutch into operation and immediately falls to a lower working value. Apparatus shown in Fig. 4 may be interposed in the drive between the clutch and the mirror so that the latter can follow a projectile moving with a constant linear velocity over a wide angular range. Disc 11, driven by the clutch, drives slide 13 at a velocity proportional to that of the projectile so that the angular velocity of disc 15, driven by pin 14, is equal to that of the projectile. The mirror on disc 16 is rotated at half this angular velocity. In another form, mirror 2 is driven by a coil 21 providing the initial acceleration and a coil 22 controlling the subsequent velocity. The coils are mounted on spindle 23 between pole pieces 24 and 25. The projectile arriving at p<SP>1</SP> operates triggering device 8 to close relay RA/1 and RA/2 simultaneously and the discharge of condenser C through coil 21 provides the initial acceleration. Arm 26 of variable resistor R9 is driven by spindle 23 so that the current in coil 22 can be varied to follow any law.
