Title: Apparatus for monitoring the heartbeat rate of a patient
IPC: A61B5/0245
Filed: 1973-06-21
Abstract: 1392155 Heartbeat monitoring F HOFFMANN-LA ROCHE & CO AG 21 June 1973 [13 July 1972] 29637/73 Heading H4D [Also in Division G1] Apparatus for monitoring the heartbeat rate of a patient provides electrical signals respectively representing beats, compares three consecutive such signals to distinguish between valid and spurious signals, and gates signals identified as valid to a storage and averaging device giving an output indicative of heartbeat rate.  In the embodiment shown, motion of a foetal heart 13 is monitored by a pulsed or CW ultrasonic Doppler system using transducers 11, 14, transmitter 12, mixer 15 and a processor 16 which gives one output pulse per heartbeat. This pulse triggers cascaded monostables 18, 19, 21, 22. Monostable 22 controls function generator 23 whose output is a voltage representing the interval between two heartbeats. The respective voltages for three consecutive beat periods are held in sample-and-hold circuits 24, 25, 26 controlled by the monostables. The contents of 24 and 25 are checked by comparator 32; the contents of 25 and 26 by comparator 33. Providing the contents match within a prescribed tolerance (e.g. a tolerance equivalent to Œ20 beats per minute) gate 43 allows gate 44 to pass the monostable 22 pulse to sample-and-hold circuit 27: otherwise, gate 44 is blocked. A further comparator 40 checks the most recent voltage sample in circuit 24 against the (assumed valid) content of circuit 27 and, if it matches, inhibits gate 43 thereby overriding any possible blocking of gate 44 by comparator 32 or 33: thus up-dating of the circuit 27 content is possible before three further heartbeat periods have elapsed. Further sample-and-hold circuits 28, 29 receive in succession the content of circuit 27. The samples of circuits 27, 28, 29 are averaged at 31 to give a signal for a chart recorder or voltmeter. An A.C. signal is fed to the recorder via 46 and 47 whenever gate 43 is inhibited, to indicate a possible spurious measurement; and/ or an audible or optical alarm is actuated. The signal in processor 16 may be recorded or aurally monitored. Phonocardiographic or electrocardiographic techniques may be used instead of the Doppler system to derive heartbeat signals.

Title: Improvements in carburetters for internal combustion engines
IPC: F02M7/24
Filed: 1924-12-10
Abstract: 237,488. Rodriguez, I. Dec. 10, 1924. Spray carburettors.-To maintain correct proportions of fuel and air, particularly with changes of altitude, the air supply to the primary mixing- chamber H and the pressure in the constant level fuel chamber J are conjointly varied in the inverse sense by a valve F. The valve casing S is connected by a pipe 1 to the fuel chamber J and by a pipe E to the main air intake B, and communicates by a pipe G with the primary mixing-chamber H. A tube M, containing a slow running jet L and connected by a pipe N to the air pipe E, is arranged concentrically in the pipe G, and opens into the mixing-chamber C through passages 0, P on opposite sides of the throttle. The primary mixing-chamber H communicates with a, perforated tube R extending transversely across the main air passage. For slow running, the valve F is positioned as shown, air being drawn in through the pipes E, N, O, and fuel through the jet. L. As the throttle is opened, the chamber H is emptied of fuel and air is drawn in through the aperture F<3> in the valve F. As the altitude increases, the valve F is rotated in a clockwise direction, which opens the pipe G and closes the pipe I. At higher altitudes, the valve F is rotated in a counterclockwise direction, which at first partly opens the pipe G and partly closes the pipe E, and finally completely closes the pipe E. The operating lever of the valve F is detachable, so that it can be moved from one angular position on the valve spindle to another, in order that the lever may be moved in the same direction to effect both movements of the valve.

[Also in Division F2] A screw 10 has an enlarged head 16 with a sealing surface 18 to which is adhered a solid coating 22 of a fluorocarbon polymer resin so that the screw forms a fluid tight seal with an object into which it is fastened: An offset cross shaped cavity 20 for receiving a complementary shaped screw driver is formed in the head of the screw. The coating is preferably polytetrafluoroethylene but polychlorotrifluoroethylene or trifluorochloroethylene may be used. The surface 18 is first cleaned mechanically, for example by sand blasting, or chemically by phosphatisinig and the coating is then applied by dipping or spraying the coating in liquid form on to the screw. The coating is hardened by sintering and then chemically etched before a second coating is applied. Several coatings are applied in this way until the coating has a sufficient thickness. In a modification the coating completely covers the surface 18, the shank portion 12 and the threads 14 and the hole into which the screw is to be inserted is lined with a sealing compound such as an accelerated polysulfide rubber compound.
