Abstract: 1,156,417. De-oxygenating liquids. BRITISH OXYGEN CO. Ltd. 28 Sept., 1967 [28 Sept., 1966], No. 43328/66. Heading B1M. A process for the removal of oxygen from a liquid containing oxygen in solution or suspension comprises bubbling an oxygen stripping gas into a flowing stream of the liquid and inducing turbulent flow in the liquid stream at a point downstream of the point of introduction of the oxygen stripping gas. The oxygen stripping gas may be introduced into the liquid through a perforated pipe, a T junction, or a porous metal or ceramic plug. The turbulent flow in the liquid may be induced by constriction of the flow or by an abrupt change .of direction of flow through a right angle. In examples nitrogen is used to deoxygenate water and fruit juices.

Abstract: 1465288 Magnetic disc apparatus INTERNATIONAL BUSINESS MACHINES CORP 8 Oct 1974 [12 Oct 1973] 43442/74 Heading G5R Magnetic disc apparatus for use with a flexible magnetic record disc 20, Fig. 6, has means 42, 50, Fig. 4, for rotating the disc, and a magnetic transducer head, such as 72, Fig. 6, and a pressure pad, such as 78, each of which head and pad in operation coacts with a respective part of a respective one of the opposite faces of the disc, the disc part coacting with the head and the disc part coacting with the pressure pad being non-registering angularly spaced parts so that contact pressure develops between the disc and the head, when the disc is rotated intermediate the head and pressure pad, without the disc being pinched between the head and pressure pad, and the pressure pad also being subjected, in operation of the apparatus, to contact pressure-illustratively with an envelope 22 enclosing the disc 20. The assembly 18 of flexible disc 20 and flexible envelope 22 may be of the type disclosed in Specification 1,260,637, and is received in slots 40, Fig. 4, of a frame 34 and then a hinged cover (36), Figs. 3, 5 (not shown), is closed to engage a rotatable tapered collet (55) on the cover (36) through disc aperture 24 into engagement with a bore 46 of a shaft 42 rotatable via a belt by a motor 50 to thereby rotate the disc. Read/write heads 72, Fig. 6 (70), Fig. 9 (not shown), are supported on opposite sides of the disc by a carriage 56 movable by a motor 66 and leadscrew 60 to displace heads (70), 72 radially of the disc. In a neutral position of the apparatus, springs (90), Fig. 7 (not shown), and 102, Fig. 4, act on shafts 84, 96, Fig. 6, so that pressure pads 74, 76, on either side of head 72 at a rear face of the disc, and pressure pads 78, 80, on either side of head (70) at the front face 20a of the disc loosely engage envelope 22, but neither head (70) or 72 engages disc 20. On energizing an electromagnet (86), Fig. 7, rear pads 74, 76 are forcibly applied to areas 74a, 76a of envelope 22 to move disc face 20a into bowed transducing engagement with head (70) projecting through slot 28 of envelope 22, such movement also moving front pads 78, 80 slightly so that spring 102 acts via pads 78, 80 on disc assembly 18 with a light position-stabilizing force which in this operative position is less than the force of spring (90) acting to return pads 74, 76 to the neutral position. Head 72 may be similarly brought into transducing engagement with the rear face of the disc on energizing electromagnet 98, Fig. 4. Opening of the cover (36) causes a leaf spring hook (106) thereon to pull pads 78, 80 away from disc assembly 18 for release thereof.

Title: Method and Apparatus for Sealing Gas under High Pressure into a Gas-Sealed Type Shock Absorber
IPC: F16F9/43
Filed: 1967-09-26
Abstract: 1,173,456. Hydropneumatic shock absorber filling methods. KAYABA KOGYO K.K. 26 Sept., 1967 [9 Nov., 1966; 11 Nov., 1966], No. 43736/67. Heading F2S. A hydropneumatic shock absorber is charged with pressurized gas by apparatus including a jig bar which is used to position a floating piston which, in the assembled shock absorber, separates the gas charge from the liquid charge. The gas is admitted to the shock absorber through an aperture associated with a loose ball inside the shock absorber. This ball is displaced from the aperture during charging and after charging the gas pressure holds the ball in the aperture. In Fig. 2, the floating piston 14 which is to separate the liquid chamber A from the gas chamber B is first set in its required position by pushing the jig bar 21 into the filling aperture 11. The liquid chamber A is then filled and the actuating piston assembly 16, 17, 18 is fitted and sealed. On subsequent removal of the jig bar the floating piston 14 remains in its set position. The gas chamber B is then filled with nitrogen (after, if considered necessary, first evacuating the original air in this chamber) by the use of the charging apparatus of Fig. 3 (not shown). When the shock absorber is removed from the charging apparatus, the ball 12 automatically closes aperture 11. Subsequently this aperture may be more positively sealed from outside. In Fig. 4 (not shown), the gas chamber B is first filled with liquid, the floating piston 14 is inserted by use of a jig bar (32) entered from above and excess liquid is extracted through the filling aperture 11 as the floating piston descends to its required position. The liquid chamber A is then filled with liquid and the actuating piston assembly fitted as before. Thus, on removal of the shock absorber from the filling means of Fig. 4, both chambers are filled with liquid. The apparatus of Fig. 5 is subsequently used to replace the liquid in chamber B by gas. This apparatus consists of a hollow rod 71 which serves the double function of mechanically dislodging the ball 12 from the filling aperture and of conveying pressurised gas from a pipeline 73. As gas is admitted liquid is displaced into a reservoir 65 with an overflow aperture 70 so positioned that the maximum hydrostatic head in the reservoir is less than the gas supply pressure by an amount sufficient to hold the valve 69 open. The appearance of gas bubbles in the reservoir will indicate completion of charging, at which point the tap 72 is closed.

Abstract: 1447778 Automatic control of speed INTERNATIONAL STANDARD ELECTRIC CORP 28 Sept 1973 [5 Oct 1972] 45524/73 Heading G3R [Also in Division H2] The speed of a universal (series-wound) motor is controlled by providing a first transistor whose base is connected to a reference voltage source and whose emitter is energized by the motor back e.m.f. to control a second transistor in the firing circuit of a thyristor in the motor armature circuit. In the arrangement shown the base of transistor T 1 is connected to a potentiometer P to tap off a proportion of the reference voltage developed by resistance R4 and Zener diode D 1 connected in series with motor field windings F2, F1 across the supply. The collector of transistor T1 is connected to the firing circuit Z which includes a transistor T2 which acts as a variable impedance to control the charging rate of capacitor C1 used to fire thyristor Th through diac D3. The transistor T1 is thus controlled by the difference between the reference voltage and armature back e.m.f. to change the firing angle of the thyristor and thus control the motor speed to a level set by potentiometer P. The use of a full-wave bridge rectifier to supply the control and firing circuit is disclosed.
