Title: Defibrillator
IPC: A61N1/39
Filed: 1976-02-23
Abstract: 1535829 Implantable heart defibrillators M MIROWSKI 23 Feb 1976 07066/76 Heading A5R In response to a command external to a patient a control circuit in an implantable defibrillator 10, Fig. 1, causes a capacitor 78 to be charged with sufficient electrical energy to convert an abnormal cardiac rhythm to a normal one and thereafter discharges the capacitor 78 through the patient's heart. In a first embodiment, Fig. 1, the implanted unit is controlled by a physician using a console 12 to transmit binary-coded control signals together with energising power from a transmitter 16 via the skin 14 to a transformer-coupled receiver 18 which directs the power to an inverter 52 and the control signals to a control register 48. A GO signal from register 48 causes inverter 52, giving a 600 volt output, to charge the capacitor 78 until the level thereon is sensed by a comparator 100 to be equal to a selected one of, for example, eight possible levels, the selected level being fed to comparator 100 from register 48 via D/A converter 108. When capacitor 78 has charged to the preset level, a ready signal deactivates inverter 52 and enables an AND gate 82 so that capacitor 78 discharges via switch 84 and relay switch 64 into a test load 68 at the occurrence of the next QR5 complex which is supplied as a syrc. signal to gate 82 via external ECG unit 26, transmitter 16 and register 48, or via an implanted ECG unit. The discharge of capacitor 78 into load 68 is externally monitored on a CRT display 32 by means of transformer-coupled transmitter 30 and receiver 28. When the physician has determined that operation of the implanted unit is satisfactory he recycles it but this time sends a control signal so that relay switch 64 charges to discharge capacitor 78 to the atriun 74. Operation of a second embodiment, Fig. 3. is initiated by the patient placing an external magnet 112 over the skin to close an internal reed switch 114, whereupon a counter 124 is reset and a timer 116 is started. When timer 116 times out a switch 118 connects a battery 120 to an inverter 52 which charges capacitor 78 to a first level corresponding to the first state of counter 124, an AND gate 82 controlling discharge of capacitor 78 to the atriun in synchronism with the QR5 complex by means of an internal ECG unit 130, 132. AND gate 82 also steps counter 124 to its second state and restarts timer 116. If magnet 112 is removed before timer 116 times out again, the implanted unit is deactivated, whereas if magnet 112 remains the capacitor 78 is charged to a second level higher than the first and is then discharged as above, the second level corresponding to the second state of counter 124. Repeated operation in this manner sequentially increases the discharge energy in steps.

Title: Improvements in or relating to gripping devices
Inventor: BRITT JACK
IPC: B66C1/54
Filed: 1955-03-15
Abstract: 797,881. Lifting devices for engaging articles. ROLLS-ROYCE, Ltd. Feb. 29, 1956 [March 15, 1955], No. 7602/55. Class 78 (4). Claws 20 carried by a resilient membrane 19 are moved to engage a load when the membrane is moved between the position shown in full and broken lines by admitting fluid under pressure to a chamber 17 the pressure in which is normally lower than the ambient pressure. As shown, the diaphragm 19 is relieved of the load on the claws 20 by engagement with portions 21b, 21c of the claws 20 with an annular portion 23 of the member 24 which also provides a seat for a valve 26 serving to indicate when the gripping device is operated, and transmits a motion to a valve member 30 providing a remote indication if the device is overloaded. The valve 26 is carried by a member 25 secured to the diaphragm 19 and serves, when the gripper is operated, to permit fluid to pass from the chamber 17 through a bore 27 and a tube 29 to a remote flow-indicator indicating the operation of the device. The valve member 30 is integral with the member 24 and is mounted on the casing 11 of the device through a bellows 14 so that it can be moved downwardly by an excessive load on the claws 20. Downward movement of the member 30 causes a spherical seat 12a on the casing to obturate passages 35 by which fluid carried to the bellows 14 by a pipe 38 can pass to a bore 32 leading to an outlet pipe 31 communicating with a remote flow-indicator which thus provides an indication of overloading. The pipe 28 serving the chamber 17 and the outlet pipe 29 are coiled to permit the movement of the member 30, 24. The claws 20 are preferably formed in two portions brazed to opposite sides of the diaphragm 19. The portion of the diaphragm receiving each claw, and the portion of the diaphragm receiving the valve member 25, may be dished and one part of each claw 20 may have a projection passing through a hole in the diaphragm 19 to be received by a socket in the portion of the claw on the opposite side of the diaphragm.

Abstract: 612,410. Impedance transformers. SPERRY GYROSCOPE CO., Inc. April 25, 1944, No. 7746. Convention date, April 8, 1943. [Class 40 (viii)] [Also in Group XL (c)] An impedance transformer for a wave-guide comprises an adjustable length of concentric transmission line connected in shunt with the wave-guide and having the inner conductor adjustably insertable within the wave-guide, whereby an impedance connected at one end of the wave-guide may be transformed to a different value by adjusting the length of the concentric line and the amount of the inner conductor insertion. Fig. 1 shows an impedance transformer connected in a section of rectangular wave-guide 11 and comprising a tubular conductor 13 closed by a plug 14. A conducting rod 16 has screw-threaded engagement with plug 14 so as to be adjustably extensible into wave-guide 11. A conducting piston 18 in sliding contact with tube 13 and rod 16 is adjustable by means of a member 19 to vary the effective length of the concentric line 13, 16. These two independent adjustments enable the amplitude and phase of the reflected wave to be varied so as to give perfect impedance matching for a source and a load connected to guide 11 on opposite sides of tube 13. In Fig. 2, the impedance transformer 12 is used to transfer energy from guide 22 to guide 23 through a circular guide 24<1> formed with a rotatable joint 28. Circular guide 24<1> is made equal to one wavelength of the T.M. mode excited in it, and the joint is provided .with quarter-wave flanges to form a wave trap. In a further modification, Fig. 5 (not shown), central conductor 16 of the impedance transformer passes right through the connecting conductor which thus consists of a concentric line. Specification 612,406, [Group XL (c)], is referred to.

Title: Process for dehydrating unsaturated aldehydes and the resulting unsaturated aldehydes
IPC: C07C45/78
Filed: 1950-03-29
Abstract: An a , b  unsaturated C3 or C4 aldehyde such as acrolein or 2-methylacrolein, which during manufacture or treatment comes into contact with water, is dehydrated by mixing with a liquid hydrocarbon before, during or after the water-contacting stage, a liquid aqueous phase practically free from unsaturated aldehyde being separated in a further stage from a liquid phase containing the hydrocarbon and substantially all the unsaturated aldehyde and of lower water content than the aldehyde-water azeotrope.  If the boiling points are sufficiently apart, the hydrocarbon and aldehyde may be separated by distillation.  Water may be removed from the hydrocarbon solution of aldehyde by a dehydrating agent or by distilling to give a bottoms containing hydrocarbon, most of the aldehyde, and practically no water, and a distillate of aldehyde and water which may be returned to a stage prior to separation of the liquid aqueous phase.  The hydrocarbon may be aromatic, paraffinic, olefinic, cycloparaffinic or cyclo-olefinic, e.g. xylene, propane or butane.  The amount added is preferably 5-10 vols. per vol. of the aldehyde.  Saturated aldehydes and ketones are separated in the aqueous phase.  Stratification is preferably effected at 0-20 DEG  C.  Extraction may be effected by flowing water and hydrocarbon in counter-current to each other through a vessel and feeding crude unsaturated aldehyde, e.g. containing saturated carboxylic compounds, at an intermediate point. The water should generally be added in an amount at least twice that of the hydrocarbon.  The ratio of water to hydrocarbon may be greater in the upper part of the column, e.g. above 1, and lower in the lower part. e.g. less than 1.  This may be effected by taking off a mixture, for example, just above the crude aldehyde inlet, fractionating it, separating into two phases with a hydrocarbon, and returning at suitable places.  In examples, xylene and a paraffinic fraction are the hydrocarbon solvents; acrolein-water azeotrope, acrolein and 2-methylacrolein mixtures with propionaldehyde, acetaldehyde, isobutyraldehyde, and acetone the mixtures treated.  A preliminary separation by distillation may be used.
