Title: Method of and apparatus for the determination of pulse amplitude
IPC: G01R19/04
Filed: 1972-12-18
Abstract: 1410245 Measuring peak amplitudes LICENTIA PATENT-VERWALTUNGS GmbH 18 Dec 1972 [22 Dec 1971 30 Nov 1972] 58380/72 Heading G1U Apparatus for determining the amplitude of pulses which exceed a predetermined minimum threshold amplitude comprises a threshold circuit 25 for determining the minimum amplitude, a circuit 24 for detecting the peak amplitude of those pulses which exceed the threshold, a circuit 23 for temporarily storing the peak amplitude, a circuit 35 for monitoring the amplitude variation of the pulses for a predetermined time following each peak and a gate 33 for blocking the transmission of the stored amplitude if the monitoring circuit indicates that the stored peak is an intermediate amplitude noise peak. The pulses are supplied by a source 20 which may be a device for measuring the size of blood particles, the peak pulse amplitude being proportional to the volume of the particle. The pulses are amplified by a linear amplifier 21 and fed through a gate 22 to the circuit 23 which samples and holds the peak value. The circuit 24 includes a differentiating circuit, the zero crossing of the output of which corresponds to the instant of occurrence of the peak amplitude and provides a spike pulse at this instant to a gate 30. The gate controls a flip-flop 31 which closes the gate 22 to prevent the passage of further pulses and starts the operation of an analogue to digital converter 32 of the successive approximation or linear ramp type. The digitized value of the peak amplitude is fed to a store 34 provided the gate 33 is open. If a noise pulse is present on the rising flank of a main pulse, a comparator in the circuit 35 compares the output of the amplifier 21 with the output of the circuit 23 and the positive output of the comparator due to the increase of the pulse amplitude following the peak of the noise pulse enables the circuit 35 to supply a pulse which blocks the gate 33. The peak amplitude of the noise pulse is therefore not transmitted to the store. The comparator provides a negative output due to the decrease of the pulse amplitude which follows the peak of the main pulse so that the circuit 35  does not block the gate 33 thereby allowing the storage of the digitized peak amplitude.

Title: Peritoneal dialysis apparatus
IPC: A61M1/28
Filed: 1970-12-10
Abstract: 1326236 Apparatus for supplying dialysis liquid HAUNI-WERKE KORBER & CO KG 10 Dec 1970 [23 Dec 1969] 58741/70 Heading BIX [Also in Division A5] Apparatus for supplying a measured volume of dialysis liquid to a patient for peritoneal dialysis comprises a flexible bag 9 for the dialysis liquid, the bag being contained in a vessel 18 of measuring liquid 17 whose level can be monitored to determine the amount of dialysis liquid in the bag, the apparatus also including a heating device for the liquids, and a device for conveying the dialysis liquid to and from the bag. As shown, the apparatus comprises a supply of dialysis liquid 5 in containers 6, 7, a measuring vessel 18 containing a measuring liquid 17, a heating vessel 27 having a heating coil 32, 34, 33 in the measuring liquid, containers 91, 101 for receiving used dialysis liquid and a control 16 whereby the dialysis may be carried out automatically. The apparatus is used to meter dialysis liquid into the peritoneal cavity of a patient 53 through a catheter 49, dialysis taking place with the peritoneum of the patient providing the dialysis membrane. In use, a pump 12 supplies the dialysis liquid 5 from the containers 6, 7 through pipes 8 and an electromagnetic valve 11 to a flexible bag 9 situated in the vessel 18 until the bag expands sufficiently to cause the measuring liquid level to contact an electrode 22 causing a signal via the control 16 to stop the pump 12 and close the valve 11. The pump 12 is then caused to reverse and the dialysis liquid is moved around a closed circuit comprising the pipe 8, a U-tube 57, and a pipe 51a, this re-circulation causing the dialysis liquid to arrive at an even temperature and allowing additional drugs to be added to the liquid by an injection needle inserted through the tube 57. The pump 12 is then caused to deliver the dialysis liquid from the bag 9 through the pipe 8, the tube 57, pipes 51, 52, and the catheter 49 into the patient 53 until the level of the measuring liquid 17 has dropped to the electrode 21 and a signal causes the pump to stop. After a preset time a pump 73 is actuated to draw the liquid back through the catheter 49, pipes 52, 77, and into the collecting containers 91, 101. The apparatus also includes electrodes 61, 62 able to detect the presence of dangerous air bubbles in the dialysis liquid and an electrode 71 able to detect a leak in the apparatus such that the dialysis and measuring liquids mix together. Electrodes 21, 22, 94, 103, 104 used in the apparatus are exemplified in detail in Figure 2 (not shown), the pumps 12, 73 in Figure 3 (not shown), the electromagnetic valves 11, 55, 76, 99, 111 in Figure 4 (not shown), and the electrodes 61, 62, 71 in Figure 5 (not shown). A wheeled unit containing the apparatus is illustrated in Figure 8 (not shown), alternative collection containers 91, 101 in Figure 9 (not shown), and an arrangement for mixing concentrated dialysis liquid with distilled water in Figure 10 (not shown).

Title: Telephone paging system and method
IPC: H04M7/16
Filed: 1968-12-23
Abstract: 1,210,590. Automatic exchange systems. BELL CANADA. 23 Dec., 1968 [4 July, 1968], No. 60999/68. Heading H4K. Individuals with radio receivers on their person may each be paged for over a telephone network by dialling a paging number which gives access to those ones of a number of transmitters serving zones in which the individual being called is given paging service. The system also provides speech connection over radio links to subscribers with mobile substations. The paging zones are cities and, as shown at the bottom half of Fig. 1 a principal city has transmitters 30 with a control circuit 34 operating on instructions from a data set 26 and associated code converter 28 and signal generator 32. Voice channels for mobile subscribers are set up over circuit 36. Of the digits dialled to page an individual with a radio receiver on his person, one set of digits indicates the particular paging control system in which records relating to the zones for service are kept, while another set of digits identifies the wanted individual. The paging control system located at the principal city comprises a computer 16 with associated call units and data sets 18. A call directed to the control system by the one set of digits can terminate on a toll switching office 12 or a local office 10, both of which offices have access over trunk circuits 14 to the computer 16 where paging data is stored. In accordance with the stored data relating to the individual to be paged, the computer 16 sets up connections by way of local office 10 to the indicated ones of the transmitters in the local complex of paging zones. The local complex includes transmitters in the principal city and in each of adjacent cities such as A, B and C. If necessary, paging may be extended over the toll switching office to other zones in other paging complexes with their own paging control systems. Where traffic is sufficiently heavy the computer 16 may be linked directly to the transmitters 30 of the principal city instead of being switched through an office. When the computer 16 finds it has paging data corresponding to a received paging number it returns a call accepted tone to the caller who can then hang up. If no paging data is on record corresponding to the received paging number a call-not-accepted tone is returned. Paging calls may be accumulated up to a certain number, or be accumulated over a fixed period of time, whichever matures first before the computer takes action. For calls to mobile substations the computers, such as 16, in the paging control systems, operate in a manner similar to paging but connect the calling subscriber to a voice control circuit, such as 36, when reply from the mobile station is established. If in any circumstance the transmitter control circuit experiences a fault it reverts a warning signal to the associated data set.
