Abstract: A method and apparatus for use in reducing the volatilization of the monomer component of bone cement is used after a prosthesis (16) is implanted and throughout the polymerization of bone cement. The apparatus (10) includes a generally annular inflatable sealing member (24) having a centrally located opening (26) therein for fitting over the exposed end (28) of the prosthesis (16). The sealing member (24) has an outer diameter (22) covering the exposed surface (19) of the bone cement (18). The sealing member (24) has a deformable surface disposed in a substantially co-planar relationship with the exposed surface (19) of the bone cement (18). The sealing member (24) is resiliently expandable by inflation and extends beyond the edges of the bone (12) defining the cavity (14), to seal the bone cavity upon the deformation of the deformable surface thereon. A pump (56) is provided for inflating the sealing member and causing the deformable surface to apply pressure to the exposed surface (19) of the bone cement (18). A valving system (38) and a pressure gage (50) are used for controlling the pressure applied to the exposed surface of the bone cement within a range of from 8-14 psi.

Abstract: A cast-on method of making the first row of knitting stitches with the use of a transverse knitting machine which has at least a pair of front and rear knitting needle beds, a carriage for left- and rightward movement along the needle beds, and a cam system containing two groups of cams disposed in the same phase for forming and transferring knitting stitches respectively. The steps of knitting plain stitches with knitting needles of either the front or rear needle bed, lifting up the knitting needles carrying the stitches formed at the preceding course to a stitch transfer position, transferring the stitches to corresponding knitting needles of the other needle bed, and simultaneously, feeding a thread of yarn on to the knitting needles at the transferred side, and knitting a given size of fabric with the same knitting needles. With this method the cast-on position of a rib or stocking stitch fabric is knitted tightly and particularly, a foundation row of stocking stitches is so closely knitted as not to be visibly distinguished from the following rows. A knitted fabric is formed by this cast-on method.

Abstract: A trayless x-ray film cassette transport apparatus includes an improved cassette gripping system which allows an x-ray film cassette (20) to be loaded through a window (18); then gripped and withdrawn inwardly to a properly centred exposure position; then ejected to project partially from the window (18) by a distance which is automatically determined in accordance with the size of the cassette (20). This ensures that small cassettes project far enough from the window to be readily grasped by an operator while avoiding ejecting large cassettes so far that they are precariously balanced in the window (18). The gripper assemble (100) holds the cassette (20) securely under a self-locking condition, such that the gripping force on the cassette (20) increases in response to and at a greater rate than an improperly imposed cassette withdrawing force.

Abstract: An output buffer circuit (10) delivers output signals of high and low potential levels at an output (V OUT ) in response to data signals at an input (V IN ). The output buffer circuit comprises an input stage (12) coupled between a relatively quiet power supply rail (V CCQ ) and a relatively quiet power ground rail (GNDQ), and an output stage (14) coupled between a relatively noisy power supply rail (V CCN ) and a relatively noisy power ground rail (GNDN). A first coupling resistor (R5) is coupled between the relatively quiet and noisy supply rails (V CCQ , V CCN ) for reducing V CC  droop in the relatively noisy supply rail (V CCN ) which in turn reduces output step in voltage during transition from low to high potential level (LH) at the output (V OUT ). The first coupling resistor (R5) has a low resistance value selected for partially coupling the supply rails while maintaining partial isolation for maintaining input dynamic threshold levels for other non-switching quiet output buffer circuits coupled to a common bus. A second coupling resistor (R5A) is coupled between the relatively quiet and noisy ground rails (GNDQ,GNDN). The second coupling resistor (R5A) has a low resistance value selected for partially coupling said ground rails while maintaining partial isolation also protecting input dynamic threshold levels of quiet outputs. The first coupling resistor (R5) is coupled between supply rail bond pads (20,22), while the second coupling resistor (R5A) is coupled between ground rail bond pads (30,32). The power rail bond pads (20,22) (30,32) are coupled respectively to split leads (24,25) (34,35) of a split lead leadframe merging respectively to a common V CC  pin (28) and a common GND pin (38).

Abstract: A medico-surgical suction system has a container 1 with an outlet 10 connected to a vacuum pump 2, and an inlet 11 connected to a suction catheter 3 via a dual-lumen tube assembly 4 one end of which is connected to the container 1 and the other end of which has a suction control 43 and a coupling 45 for the catheter. A valve 100 located in the outlet 10 of the container 1 is connected to the suction control 43 via a minor lumen 41 of the tube 4. A side lumen 106 enables the vacuum pump 2 to apply reduced pressure to one end of the valve 100, which holds the valve off against the action of a spring 107. Actuating the suction control 43 allows air to flow to the valve 100 via the minor lumen 41 so that the effect of the reduced pressure is overcome and the spring 107 opens the valve 100, thereby applying suction to the catheter 3.
