[Also in Group VI] A hand-stapling device comprises a hooked frame 1 and a clamping rod 4 between which an organ to be sutured by the staples is gripped and a staple driver plate 9 which is actuated by a single thrust on a movable handle 7 to eject staples from a magazine 13 on the clamping rod and bend them against recesses in a die 3 fixed on the hooked frame, the arrangement being such that the staples extend across the line of suture. The body 1 of the device has a hook 2 which carries the die 3. The clamping rod 4 is slidable in the body 1 and has a box-like head 12 which receives the staple magazine 13. Tissue to be sutured is clamped between the hook and the head of the clamping rod the position of which is adjustable relative to the body by a nut 6. A pivotal handle 7 is movable relative to a fixed handle 5 and has a portion 11 which engages a rod 10 which is slidable within the clamping rod and carries a staple driving plate 9, having teeth corresponding to slots 13<1> in the magazine. The pivotal handle carries a lever 18, 19 which in one position abuts a projection 20 on the fixed handle to lock the pivotal handle in inoperative position and which in another position permits the pivotal handle to be moved towards the fixed handle against a spring 8. When the handles are squeezed together, the staple-driving plate 9 is projected so that the staples are driven simultaneously from the magazine to pierce the tissue and are bent against the die recesses. The magazine slots and the die recesses are arranged so that the staples are positioned parallel to one another. A strip of fibrin is clamped over the slots of the magazine by a clamp 16 so that in the event that the tissue to be sutured is not as wide as the height of the magazine, surplus staples ejected from the magazine will be caused to grip the fibrin strip and may be removed.

Abstract: 1278490 Multiplex pulse code signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 June 1969 [27 June 1968] 32374/69 Heading H4L In a synchronous transmission system for the transmission of binary singals employing random access for radio transmission between two stations associated with a plurality of stations in a network, in which each binary digit is constituted by a predetermined number of pulses which are time modulated to form an address signal, synchronism between the transmitter and receiver is maintained by the periodic repetition of the address code and the character (1 or 0) of the binary digit is determined by a position modulation of the pulses, means being provided at the receiver for determining whether the received bit is a 1 or a 0 even when one or more of the address code pulses are disturbed. As described, the address pulses are in a reference position for binary 0 and may be shifted either forwards or backwards by a pulse width to represent binary 1. At the receiver, the received pulses are supplied to a discriminator DP which is made operative only during the intervals corresponding to the correct address by comparing the input pulses with a sawtooth voltage which passes through zero at points in time corresponding to the reference position of the pulses. If binary 0 is received the output of DP will be zero and if a 1 is received the output will be a positive or negative value depending on whether the pulses are lagging or leading with respect to the reference position. At T the output of DP is shaped into a squarewave and supplied to a device D producing a positive spike for each phase-shifted pulse which is supplied to an integrator AC. The output of the integrator is supplied to a level testing circuit having a threshold value which is arranged so that at a predetermined voltage level from the integrator a binary 1 is recognized and with no output the digit is assumed to be binary 0. The detected digit is supplied to a utilization circuit B.
