Title: Improvements in or relating to circuit arrangements for association with telephone lines
IPC: H04M3/38
Filed: 1968-06-21
Abstract: 1,220,958. Automatic exchange systems. SOC. GENERALE SEMICONDUTTORI S.p.A. 21 June, 1968 [27 June, 1967], No. 29792/68. Heading H4K. A blocking circuit comprises a counter adapted to count the number of pulses relating to the first digit dialled into a telephone line and to open a contact in the line in response to the detection of predetermined counts, the counter being reset if the telephone receiver is returned to the switch-hook. The arrangement shown is connected to the telephone line 2 by a transformer 4 and includes a contact a, which it can open to cause the line to be released when the first digit dialled is a "0", "1" or "9". When the receiver is lifted a switch-hook contact I closes to apply earth to a circuit 10 incorporating a delay as determined by the values of R2 and C2. The output resets an electronic counter 8 and a bi-stable 11, and enables a "slow to release" circuit 7. Dialling pulses arriving from the line are regenerated by a monostable circuit 6 and applied to the circuit 7 which gives a continuous output while the pulses of the first digit are being received, and to the input of the counter. The output of the circuit 7 and the output of an 'AND' gate G4 which is wired to respond to the count of zero of the counter, are combined to give a continuous signal which operates a bi-stable enabling the counter while it is reset and while the dialling pulses of the first digit are being received. The counter which comprises four cascaded bistables is thus only enabled to count the pulses of the first digit. Three "AND" gates N 1 , N 9  and N 0  are connected to the outputs of the counter so as to be enabled at the counts of 1,9 and 10, respectively. Thus if the counter stops on one of these counts the corresponding gate N 1 , N 9  or N 0  is enabled for a period sufficient to operate a relay A 1  which opens the contact a 1  in the line.

Abstract: 989,885. Collecting blood. BAXTER LABORATORIES Inc. Aug. 18, 1961, No. 29810/61. Heading A5R. Apparatus for collecting blood comprises a flexible collecting tube, means for facilitating separation of a part of the tube from the remainder and a pointed cannula positioned in the tube so that separation of the tube exposes its pointed end. The collecting tube connects a phlebatomy needle 22 with a plastic blood receptacle 24. The tube comprises two tube portions 21, 23 joined by a coupling 30 which incorporates a cannula fixed to the tube portion 21 carrying the phlebatomy needle. When the two parts of the coupling are disengaged the point of the cannula is exposed. For collecting a blood sample the cannula is caused to pierce a self-sealing closure 57 of a sample tube 56 attached to the main receptacle. The tube portions may be in one piece weakened circumferentially in the region of the cannula or may be sealed together in the region of the cannula. For taking a blood sample the weakened portion (not shown) or the seal 35 is broken, thus exposing the cannula point. The tube portion 23 adjacent the receptacle may have a closing diaphragm 37 or plug (Fig. 5, not shown) which, when the collecting tube is used to conduct blood to the receptacle, is pierced by the cannula on axially collapsing part of this tube portion over the cannula. The plug or diaphragm is self-sealing on withdrawing the cannula from it. The adjacent ends of the tube portions may be connected by a sleeve (Fig. 5, not shown) which covers a portion of the cannula and is withdrawn with the tube portion 23 from the cannula to expose its point. Either or both tube portions may have exterior sleeves (Fig. 6, not shown) fixed to them, the sleeves being detachably interfitting over the cannula. The end of the tube portion to which the cannula is fixed may have a coupling portion 48 (Fig. 11) including a radial flange 49, the end of the other tube portion carrying a funnel-shaped coupling portion 54 which detachably engages the flange. A diaphragm closure integral with the funnel-shaped portion is located in the other tube portion and is punctured by the cannula on deforming the funnel-shaped portion over the cannula. When the main receptacle is filled, the tube portion 23 connected to it is divided by heat-sealing into segments each containing a blood sample and individually marked for identification.
