Title: Direct-indicating apparatus for determining the heart time volume by the thermodilution method
IPC: A61B5/028
Filed: 1975-05-23
Abstract: 1515143 Measuring heart time volume by thermodilution CONTRAVES A G 23 May 1975 [24 May 1974] 22736/75 Heading G1N(E) In an apparatus for determining the heart time volume by thermodilution employing a digital computer 2, two thermistors 10, 20 in a catheter 1 are positioned within the body, one 10 is adjacent the point (e.g. the right atrium) where a cold fluid is injected into the blood stream to measure the entrance temperature, and the other 20 is positioned downstream (in the pulmonary artery) for measurement of the thermal dilution. The thermistors 10 and 20 are each connected to temperature/pulse frequency converters 11, 21 which supply a multi-plexer 6 whose control input is connected to a scaling device fed by pulses from a timer 4. The multi-plexer alternately transmits signals from the converters 11 and 21 to a gate circuit 7. The gate 7, also Fig. 5 (not shown) is such that the pulse frequency transmitted by the multi-plexer in each instance is read from the converters 11 or 21 respectively as a mean value over 31 periods. The pulse trains generated in the gate 7 are fed to a counter 8 supplying an intermediate store 9 that is connected to the digital computer 2 along with the outputs from the scaler 5 and the timer 4. The resulting signal is then processed according to the "Stewart-Hamilton formula" (as disclosed in the description).  The description also explains how the device may be calibrated, Figs. 2, 3 (not shown).

Title: Pcm switching system
IPC: H04Q11/04
Filed: 1970-05-12
Abstract: 1,243,618. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 12 May, 1970 [19 May, 1969], No. 22848/70. Heading H4K. In a computer-controlled, PCM, TDM switching centre, separate switches are provided for the. two directions of transmission each switch being separately addressed from the computer in order to set up a bidirectional transmission. The virtue of switching each direction separately lies in the use of the centre for essentially one sided calls, e.g. data collection from a remote point such as a monitoring point or a computer or a computer peripheral, in radio relay broadcast calls, and in multichannel music transmission. The centre utilizes sixteen, thirty-two channel highways in each direction, of which one highway is reserved for computer originated switching commands while two channels on each highway are utilized for synch. and supervisory signal purposes. Certain outgoing highways from one switch may be connected as incoming highways to the other switch to allow bidirectional transmissions between circuits at a same terminal, but if this is done the essentially non-blocking nature of the switching centre is sacrificed. Both switches may be controlled over a common channel if an interswitch data link is provided and if the switching instructions are accompanied by coded bits indicating the destinations thereof, but a slower system speed is thereby entailed. Free/busy conditions are determined by addressing the memories in a random access made whereas path tracing is effected by cyclic read-out of the memories and comparison of the resultant data with data in the computer.

Non-solvent liquids such as bromobenzene, benzene hydrocarbons, chlorinated hydrocarbons, petrol, and tetrahydronaphthalene, may be added to any of the solvents. Catalysts such as ammonia, organic bases, hexamethylene tetramine, substituted phenol such as nitrophenols, nitro-cresols, phenylamino-cresol, picricacid, styphnic acid, picamide, trinitro-phenetol, picramic and iso-picramic acids, in amounts of 3-5 per cent may be included in the lacquers. Fireproofing media such as ammonium carbonate or sulphate or magnesium chloride or sulphate may also be added to the lacquers. Various methods of obtaining B resin are described, and Specification 1921/08, [Class 70, Indiarubber &c.], is referred to in this connection. Finely ground C resin may be added to A resin and the latter converted to B resin whereby lacquers containing finely divided O resin are obtained. The lacquers are applied and the solvent evaporated by passing air or neutral gas at ordinary or raised temperatures over it. If it is desired to harden the lacquer, further heating optionally under pressure, is effected. The solution may be used for impregnating under vacuum and pressure, for cements and with the addition of organic or inorganic fillers, for press mixtures, grinding discs, &c. The Specification as open to inspection under Sect. 91 (3) (a) describes also, dissolving phenolaldehyde B resins in any suitable solvents and states that solvents which do not dissolve B resins, such as benzene and alcohol may be used if solution is effected under heat and pressure. This subject-matter does not appear in the Specification as accepted.

In a system in which selection signals are sent from a substation in voice-frequency form, a VF signal does not become effective at the receiving equipment until it is followed by a further signal, e.g. a break impulse. As shown, different frequencies are sent by means of pushbutton contacts T1 . . . T10 and are passed by way of filters F1 . . . Fn at the exchange to monostable circuits M1 . . . Mn. A common contact Tg connects the generator G to line, and a relay R disconnects the subscriber's set at contact c, so that when contact Tg restores the line is interrupted during the release time of relay R. A circuit KE responds to this interruption and places the receiving circuit A under the control of circuits M1 . . . Mn. In another embodiment, Fig. 3 (not shown), the direction of line current is reversed at the exchange after each VF signal, and a switching contact at the substation connects up oppositely-directed rectifiers.

Abstract: 536,248. Automatic ticketing apparatus. STANDARD TELEPHONES & CABLES, Ltd., WOOLLEY, G. H. W., and HENDERSON, M. W. Aug. 15, 1939, No. 23545. [Class 40 (iv)] Automatic ticketing apparatus comprises means for printing a series of invariable headings on a paper strip, means for printing the usual variable information against these headings and means for severing the strips to form a ticket. When a ticket is to be printed a motor MS is started from control apparatus (not shown) on which the first character to be printed is indicated by the connection of lead T to the corresponding position in the bank of a switch 8. The type wheel 22 and switch 8 are on a shaft 7 driven via a slipping clutch and when tbemarked position is reached, magnet 11 is operated to stop the shaft 7. Groups CT, CP, CG of cams are coupled to a driving shaft 3 by slipping clutches and are normally held stationary by magnets 24, 36, 45, momentary operation of which allows the cam group CT, CP to make one complete rotation and group CC half a rotation. Magnet 24 is operated at the same time as magnet 11 and both are released when cam 32 moves off normal. Cam 27 operates typing hammer 29 and shifts the type wheel 22 one space axially to the right and cam 34 operates magnet 12 to re-start shaft 7 and sends a signal over TS to the controlling apparatus to cause the marking to be changed. The second and subsequent characters in the line are then printed in a similar way. At the end of the line, ground on P causes a momentary operation of magnet 36 whereupon arm 41 controls the release of the type wheel 22 to its normal axial position, the advance of the paper strip and the advance of a printing roller 73 bearing the invariable matter and arm 40 subsequently operates printing hammer 74 to impress this invariable matter on the next ticket. Before the finalitem has been printed,cam 64 energizes magnet 45 to release the cam group CG whereupon roller 161 is drawn across the end of the ticket to form a sail thereon to assist its pneumatic despatch. Three blank lines are allowed after the printed matter, magnet 36 being held operated over cam-controlled springs 67. Finally magnet 48 allows cam group CG to make the second half of its rotation and lever 51 operates guillotine blades to cut the ticket off.
