Patent GB-912255-A (GB)
Abstract: 912,255. Calculating apparatus. NATIONAL CASH REGISTER CO. Aug. 9, 1961 [Oct. 19, 1960], No. 28734/61. Class 106 (1). An accounting machine has means for entering an old balance into the machine, either automatically from a record, or manually, and a symbol printing mechanism prints on the record symbols distinguishing the two kinds of entry. It is preferred that the invention be incorporated in the accounting machine disclosed in Specification 852,827. If the link 110 is in the position shown in Fig. 1, print wheel 20 presents to hammer 22 a symbol indicating automatic entry of old balance. If the link 110 is moved by arm 104, acting on pin 108 on the link, segment 30 moves gear-wheel 28 to cause print wheel 20 to present to the hammer an adjacent symbol indicating manual entry of the old balance. A solenoid is operated when a manual input or remake operation is initiated and this brings a low spot 50 on the surface of print selection plate 48 (Fig. 2) opposite a feeler arm 52 urged clockwise by a pitman 78. The arm 52 is wide enough to sense both selection plate 48 and an adjacent selection plate 66 (Fig. 1) having a low spot 72 thereon, which is brought opposite feeler arm 52 under the control of the total control row of the machine. When low spots 50 and 72 are in registration opposite the feeler arm 52, a pitman 86 can move to the left bringing a stud 130 on link 92 in the path of an arm 132 which is moved anti-clockwise at an appropriate time in the machine cycle by cam 146 on driven shaft 76. The resultant movement of link 92 moves arm 104 anticlockwise, setting up the manual entry symbol on print wheel 20.

Adhesive 13 is applied between end caps 9, 10 and outer surfaces of tube 1 and bushings 2 prior to the pressing steps. The spacers 7, 8 may be integral with the end caps 9, 10 respectively, (Fig 7). <IMAGE>

Title: Electrosurgical trocar assembly with bi-polar electrode
Inventor: GENTELIA JOHN S
IPC: A61B18/14
Filed: 1993-02-05
Abstract: A trocar assembly 10' includes an elongate trocar device and a surrounding cannula 14'. The trocar device incorporates an electrosurgical cutting element 28' which is used to make a guide hole for the cannula and thus enable the remainder of the assembly to enlarge the puncture. The cutting element comprises a bi-polar electrode assembly 28a, 28b and insulation 28c. A control circuit senses the current flow to the cutting element and, when the trocar device breaks through the wall of the body cavity being cut into, cuts off the connection to the associated electrosurgical generator. Further control circuitry prevents a surgeon from resuming electrosurgery until a predetermined time has elapsed. Multiple trocars 16', 18' of different diameters are provided for the same assembly. An additional lead may be provided to compensate for leakage impedance (Figure 10). The inner trocar member 16' may have a high temperature resisting insulating tip (Figure 11). <IMAGE>

Abstract: Sheet grippers 6/7 carried by a chain 2 are opened when a surface 9/10/11, contacted by gripper-control rollers 4, is moved from an inoperative position to the operative position shown. A cam 12 effects the necessary movement of member 8 and its surface 9/10/11. When member 8 is in the inoperative position, gripper-control rollers 4 contact surface 10, but do not cause separation of gripper parts 6 and 7. Member 8 may be pivotable about a single point (figures 3 and 4), rather than carried by arms 16. <IMAGE>
