IPC: G01R33/05
Filed: 1966-06-14
Abstract: 1,085,682. Electro-physical measurements. LOCKHEED AIRCRAFT CORPORATION. June 14, 1966, No. 26554/66. Heading G1N. A magnetometer comprises a thin bi-stable magnetic film e.g. of "Permalloy" 1700‹ A. thick, deposited on a glass support and having easy and hard axes of magnetization perpendicular to one another and a square hysteresis loop characteristic along the easy axis. A "pumping" coil is wound around the easy axis and energized with sinusoidal A.C. to repeatedly switch the film about its two-stable states. A search coil wound around the hard axis gives an A. C. output proportional to ambient magnetic field along that axis. The search coil is preferably tuned by a capacitor to resonate at the fundamental or a harmonic of the pumping frequency. With the sensing coil operating at an even harmonic, e.g. the fourth harmonic, the sensitivity is increased (e.g. 250V per oersted), but the amplitude is limited. Thus in harmonic mode the magnetometer may be operated in a null system, with a D.C. bias coil opposing the ambient field. Fig. 2 (not shown) illustrates a Colpitts transistor oscillator and emitter follower for driving the pumping coil e.g. at 3M/Cs and the output of the sensing coil is fed to a rectifier and microammeter.

The cell comprises a silver probe electrode 25, a helical working electrode 23 of platinum wire aligned with a window 28 in a platinum counter electrode 24, and an inlet 29 and outlet 30 for inert gas. Luminescent radiation passes through window 28, slit 10, filter 1, slit 12, and is then received by a photomultiplier 11. The photomultiplier output is read on a milliammeter or a pentype recorder and an oscilloscope, which also monitors the cell voltage (Fig. 3, not shown). A further embodiment (Fig. 4, not shown) employs a single cell located between two rotatable filters, each filter having an associated photomultiplier. One filter operates over the U.V. range of the spectrum, the other over the visible region. The filters are used sequentially such that when the visible region filter is being used a shutter obscures the slit corresponding to the U.V. detector, and vice versa. The filters are mounted on the same shaft which is motor driven, so that the output from the operative photomultiplier may be applied to a pen-type recorder to enable the spectrum of electroluminescent radiation from the liquid to be scanned.

Title: Magnetic suspension systems
IPC: F16C39/06
Filed: 1963-07-09
Abstract: 1,030,508. Automatic position control. J. LYMAN. July 9, 1963 [July 20, 1962], No. 27145/63. Heading G3R. In a system in which a body is magnetically suspended, variable intensity magnets tending to move the body in opposite directions along an axis are differentially controlled by movements of the body along the axis to maintain the body in a desired position automatically. In Fig. 1 (not shown) a body 10 to be suspended is attached to permanent magnets 11, 12 which are maintained coaxial within cylindrical permanent magnets 15, 16 by repulsion. Any axial movement causes a conical member 26 to increase or decrease, according to the sense of movement, the amount of light from a source 30 reaching a photocell 31 so that the excitation of A.C. electromagnets 18, 19 attracting cores 22, 23 is varied differentially to restore body 10 to its desired axial position and also contribute to its radial stabilization. Body 10 may include magnetic elements and be rotated by a polyphase stator in which case the permanent magnets may be of non-conductive material such as ferrite. The entire system may be enclosed in an evacuated casing. In Fig. 3 (not shown) electromagnets 63, 64 at each end attract ferrite discs 61<SP>1</SP>, 62<SP>1</SP> attached to a rotated body 60 which may form part of a gyro. The coils of the electromagnets form part of resonant circuits 73, 74 supplied from an oxillator 72 and axial movements are opposed by the changes in energization of the coils brought about by changes in their inductance due to movement of discs 61<SP>1</SP>, 62<SP>1</SP>. The system is damped by rate feedback circuits 79, 80 which may be of the resistance-capacity type. External forces acting on the system may be measured by measuring the difference in voltage across the two coils and this signal may also be fed back to eliminate persistent errors. In a modification, variable inductance electromagnets are also arranged to stabilize the radial position of a shaft. Axial movement influencing bridge circuits or magnetic amplifiers instead of resonant circuits is referred to.

Title: Method for the treatment of malignant tumors
IPC: A61K35/742
Filed: 1964-07-01
Abstract: A method of treating malignant tumours in vertebrates other than human beings comprises parenterally administering to such vertebrates spores of a non-pathogenic, anaerobic strain of a microorganism of the genus Clostridium capable of localising in tumours and causing oncolysis thereof in conjunction with an anti-tumour chemotherapeutic agent selected from 5-fluoro-deoxyuridine or an alkylating agent of the ethyleneimino type, the latter being administered so as to be present in the animal body during the time of maximum oncolytic effect of the spores.  Preferred alkylating agents of the ethyleneimino type are Mitomycin C, sec-1-ethyleneimino-2-hydroxy-butane, 2,5-bis (ethyleneimino)-3,6-bis-propoxy-1,4-benzoquinone, and 2,3,5-tris-ethyleneimino-1,4-benzoquinone.  The anti-tumour agent may be administered 1-3 days after injection of spores, or 1-3 days prior to spore injection to build up a body level, followed by lower maintenance doses after injection of spores.  The p  anti-tumour agents may be administered dissolved or suspended in physiologically acceptable diluents or carriers.

Abstract: 368,797. Friction clutches ; variablespeed gearing. BETHLEHEM STEEL CO., Bethlehem, Pennsylvania, U.S.A.- (Assignees of Nieman, H. W. ; 115, East Market Street, Bethlehem, Pennsylvania, U.S.A.) Sept. 11, 1930, No. 27204. Convention date, Sept. 12, 1929. [Class 80 (ii).] In clutch-mechanism for power-driven machines, a driving-member is engaged by a flexible wrapping friction band connecting the driven shaft to a control shaft, between which and the driven shaft a constant clutch-engaging torque is exerted. By nullifying this torque the clutch disengages, and can be arranged to re-engage gradually by virtue of inertia provided on the control shaft. An expansible band-clutch element 19 coacts with a driving- drum 14 revoluble on the driven shaft 12, from which power is transmitted by a pinion 45, one end of the element being connected to an arm 18 on the shaft 12 and the other to an arm 16 secured to the control-shaft 11 and projecting through a slot 17 in the shaft 12. The clutch element 19 comprises two outer friction-faced bands 21 connected together by a bridge-piece 27 and to a similar inner band 24, the free ends of the bands 21, 24 being connected at 33, 30 respectively to the arms 18, 16. The shafts 11, 12 are coupled by a torsion spring 36, set to a predetermined adjustable stress by a ratchet 38 and pawl 39, the torque on the control-shaft 11, which is amplified by the clutch 19, 14, being thus maintained constant during rotation of the shaft 12. By applying a brake 42 to the shaft 11, the effect of the spring 36 is nullified and the clutch disengages. The shaft 11 can then be turned by a hand-wheel 35 for the purpose of power-" inching " the driven machine. The control-shaft is given considerable inertia, e.g. by employing a massive hand-wheel, in order to reduce the starting- acceleration on release of the brake 42.
