Title: Device for prosthetic or percutaneous use having a surface or lining compatible with blood or other tissue and method of making same
IPC: A61F2/06
Filed: 1971-09-22
Abstract: 1347791 Coated prosthetic device TECNA CORP 22 Sept 1971 [1 Oct 1970] 44166/71 Heading B2E [Also in Divisions A5R and B5A] A prosthetic device having a surface compatible with blood and living tissue and adapted to receive ingrowth of living cells from an interfacing region of tissue or blood is produced by incorporating microcavities in the surface by embedding particles, granules or fibres into the material forming the surface to a depth of 0.002-0.020 inches, while the surface is soft, thereafter removing the particles, granules or fibres leaving a surface containing cavities having a shape and size corresponding to. the embedded portion of the particles, the granules and fibres. As shown in Fig. 1, a layer 12, e.g. of silicon rubber, heat-curing polyurethane or solvent-evaporation polyurethane is applied to the surface of a prosthetic device. Fibres are flocked on to the tacky surface 12, layer 12 thereafter hardened by solvent evaporation or irradiation heating, and the fibres thereafter dissolved out of layer 12 by a solvent. The substrate may be a metal or metal alloy such as stainless steel, aluminium, ferrous-nickel, titanium, polyproylene, polyethylene terephthalate, nylon, polycarbonate, silicon rubber, polyurethane or natural rubber. The fibres may be nylon, polyethylene terephthalate or acetate. In another embodiment microcavities are formed by using sodium chloride crystals as the particulate material which are subsequently dissolved with distilled water. As shown in Fig. 4 a mould 26 is provided with a polymer adhesive layer 27 which in its soft condition is flocked with flocking material 28. Layer 27 is thereafter set or hardened and surface layer 29 is applied over the surface. The resulting moulded object 29 is then removed from the mould along with layer 27 and the embedded particles 28 which are then dissolved leaving a plurality of internal microcavities 31. Applications mentioned are external coatings for percutaneous lead devices such as tubes, shunts, tannulae, insulated wire and other tubular or mass, energy and information transport devices which provide an external connection to a point beneath the skin.

A circuit for transmitting parts of signals exceeding a predetermined threshold comprises two valves 12, 13 having a common load 14 gated alternatively on and off by two outputs A, B obtained from a trigger circuit 51, the state of which is determined by whether or not the input signal at E exceeds the threshold level. As described, input signals at E are fed via amplifiers 31, 33 and limiter 32 to a bridge rectifier 37 to produce a D.C. signal, the amplitude of which is proportional to that of the A.C. input signal. This D.C. is applied to two cascaded Schmitt triggers 41, 51 which are arranged to trip from one state to the other at the threshold point, and so block either valve 12 or 13 which have a common cathode load 14. For signals exceeding the threshold, valve 12 is unblocked, and signals at E pass via amplifiers 10 and valve 12 to the load 14. For lower level signals valve 12 is blocked, preventing transmission of the signal, but the mean D.C. in the load is unchanged due to the conduction of valve 13. A variable resistor 62 is provided for initial balancing of the circuit and a neon 59 indicates the state of trigger 51.

Title: Method and apparatus for increasing the number of strokes performed by pneumatic piston cylinder devices in a given period of time
IPC: B25C1/04
Filed: 1964-11-03
Abstract: 1,018,470. Stapling and nailing device. SENCO PRODUCTS Inc. Nov. 3, 1964 [Nov. 5, 1963], No. 44763/64. Heading B4C. A pneumatic fastener applying device, such as for stapling or nailing, comprises a piston movable through working and return strokes under the control of manually-actuated valve means 20, 22, 24 and pneumatic means 42, 44, 46 for initiating and sustaining repetitive operation of the piston so long as the control means is actuated. The control means is in the form of a piston 22 adapted to unseat a ball valve 24 upon actuation of a trigger 20 so as to allow compressed air to flow from a reservoir 18 through the valve 24 and operate a further piston firing valve which then admits air into a cylinder 10, Fig. 2 (not shown) to drive the piston 12 on its working stroke In order to provide for continuous operation, the compressed air, when the piston 12 reaches its lower position, flows through a port 36 into an annular chamber 37 and then through a port 42 to act on a piston 44. Movement of the piston 44, via a lever 46, moves the trigger downwardly against the pressure of the operator's hand so that momentarily the valve 24 is closed and permits the piston 12 to return. Directly the port 36 is closed by the latter piston, the piston 44 returns so as to allow the valve 24 to be opened and initiate another working stroke. If it is desired to use the tool for " single-shot " working, the piston 44 may be moved by some manual means in order to close the port 42. In the modification shown in Fig. 4, the device is mounted on a pivot 56 and maintained in a raised inoperative position by means of a spring 53. In operation, upon actuation of a foot-controlled valve 60 air is fed, via a pipe 58 and valve 68, to act on a ram 55 which pivots the device so that the driver guide 35 abuts a support 64, at the same time the air actuates the driver piston 12 as previously described. At the end of the working stroke, air passes through the port 42 and pipe 66 so as to act on the valve 68 and so allow the piston 12 to return; the function of the device is then similar to the previous embodiment.

A skirt is fashioned on a straight-bar machine by introducing yarn carriers J2, J3 in addition to the main carrier J1 and simultaneously operating transfer points 10, 12, 14, 16 to effect fashioning midway across the width of the skirt as well as conventional fashioning at the extreme edges such that three fashioned strips 1a, 2 and 3 are produced following the body 1 of the main portion. The yarn carriers J1, J2, J3 feed the yarn for the separate knitting of the strips which are continuously fashioned to provide the upper waist portion of the skirt. On completion the two outer srips 1a and 3 are bodily transfer inwardly and a course or courses is or are knitted across the full width of the fabric to join the strips together at their upper edge. The slits extending between the portions are subsequently sewn or otherwise secured together to close them. A waist band may be knitted on to the top of the skirt and may be either preformed and knitted on to the top or actually produced by a subsequent knitting operation. A few additional courses knitted on the top of the waist may serve as an edge to which a lining for the skirt may be secured.

Abstract: 1,162,498. Monitoring systems. ATLANTIC RESEARCH CORP. 11 Oct., 1966 [22 Oct., 1965], No. 45371/66. Heading G4H. In a system for monitoring the condition of remote points the data from the remote points includes coded information representing both the condition of the remote points and their location. In the embodiment described (Fig. 2) a change in the condition of a remote point is indicated by an input on a line 14 to a transfer circuit 50 which results in an output signal being applied to one of the AND gates in one of the groups of AND gates 130a . . . 130p. A distributer 102 sequentially enables AND gates 108 to 122 and supplies pulses on a lead 106 to a binary coded counter 104. The output from the counter is applied to a binary to decimal converter 126 which gives an output on one of lines 128a ... 128p to enable one of the groups of AND gates 130a ... 130p associated with the remote points 132 . . . 132p. The " 1 " or " 0" outputs from the enabled AND gates represent the changes in state of the members at the associated remote point and are transmitted through OR gates 134 . . . 140 to AND gates l16 . . . 122. The count in the counter 104 representing the remote point being monitored is also fed to AND gates 108 . . . 114 so that as the distributer 102 sequentially enables the AND gates a train of pulses is transmitted through OR gate 124 representing the location of the remote point and the state of the monitored members there. The outputs from lines 10 and 11 of the distributer 102 are also transmitted through the OR gate 124 as stop pulses. The output train is inverted at 142 before being fed to a regenerator 144 which samples the train at the mid-point of each time interval in which a bit of information is transmitted.
