Filed: 1968-09-16
Abstract: 1,254,452. Wells &c. BRITISH PETROLEUM CO. Ltd. 22 Aug., 1969 [16 Sept., 1968], No. 43936/68. Heading E1F. An oil bearing formation in which, or just below which, a borehole terminates is heated by: separately and continuously introducing oxygen and fuel into the bore hole, continuously mixing the oxygen and fuel in the end of the bore hole to form an explosive mixture and intermittently igniting the mixture to generate heat and shock waves which pass into the formation. The invention is applied to formations part way down a borehole by sealing the borehole just below the formation. The oxygen is supplied in air and the fuel is hydrogen. A packer 40 having chambers 44, 45 is set in the borehole and air is supplied to the bottom of the hole by a tube 42 to drive formation fluids into the formation. Fuel supplied by a tube 41 to the chamber 45 mixes with air from the chamber 44 to form an explosive mixture which continuously passes to a chamber 46 to be ignited at intervals by a sparking plug 47. Explosive waves are controlled by a helical tube 47 cooled by water which is mixed as steam with the combustion products. In a modification a burner according to Specification 1,254,453 is fixed in the borehole below a seal.

Abstract: 1,205,216. Mass spectrometers. PYE Ltd. 4 Jan., 1968 [5 Oct., 1966], No. 44397/66. Heading H1D. In a mass spectrometer ion source for producing only parent ions of a test substance, the test substance which may be in the form of vapour, possibly intermixed with an inert carrier gas, or in the form of a coating on a target, within an ionizing chamber 7 is bombarded with a beam of metastable atoms of an inert gas, preferably Ar, but possibly He, Ne, Kr or Xe, the metastable atoms being produced at a surface bombarded at grazing incidence by an ion beam of the same inert gas. In the arrangment shown an ion beam of this inert gas produced in a discharge chamber 1 having an anode 2 and a cathode 3 passes at grazing incidence through the hole 6 in a metal plate 5. Alternatively the ion beam may produce metastable atoms by reflection from a metal plate at grazing incidence.

Title: Implantable heart pacemaker
IPC: A61N1/365
Filed: 1972-09-26
Abstract: 1401247 Heart pacemakers SEIMENS AG 26 Sept 1972 [4 Oct 1971] 44503/72 Heading A5R A heart pacemaker operable with a predetermined maximum battery voltage includes control circuitry which is responsive to heart action in such a manner that the respective voltage amplitudes of successive stimulating output pulses are successively decreased until a pulse fails to stimulate the heart, the voltage of the next pulse then being raised relative to the ineffective pulse by an amount which is small relative to said maximum battery voltage but is sufficient to ensure stimulation of heart action, thus enhancing battery life. A pulse generator 10 supplies square wave pulses at about 70 p.p.m. at outputs A1, A2, the output at Al rendering a transmitter 12 conductive to discharge a capacitor 13 through the heart. Capacitor 13 is charged from a larger capacitor 15 which is not recharged until the absense of a QRS pulse is detected thus successive pulses from capacitor 13 decrease in voltage until they are not large enough to stimulate the heart. An amplifier 18 receives signals from the heart and gives an output pulse each time a QRS pulse is detected. The output A2 of generator 10 passes to a monostable multivibrator 20, which gives an output pulse A after a predetermined delay of 150 to 250 m.sec (e.g. 200 m.sec) following each pulse from generator 10, and to a bistable multivibrator 19 having an input I, from amplifier 18 and an output A. If a QRS pulse is detected within said predetermined delay after each stimulating pulse, circuit 19 gives a positive output causing a gate 22 to block a charging path to capacitor 15. If no QRS pulse is detected the outputs of both circuits 19, 20 are negative and gate 22 opens to charge capacitor 15 via diode 23 and resistor 24 to increase its voltage by a step of 0.1 to 0.5 volts. A line 25 may connect the output of amplifier 18 to generator 10 to inhibit the generation of stimulating pulses when QRS pulses are detected, capacitor 15 being constantly charged via a high resistor 27, e.g. 30 megohms, so that its voltage does not greatly decrease during prolonged periods of pacemaker inhibition.

Abstract: 1325497 Feed control SIEMENS AG 22 Sept 1970 [23 Sept 1969] 45175/70 Addition to 1216000 Heading B3B [Also in Division G3] In a lathe, the tool traverse and/or the depth of cut is reduced until the spindle torque exceeds an upper threshold, and in-feed is carried out up to a maximum of the programmed contour as long as the torque undershoots a lower threshold, the vibrations of the tool and/or workpiece being measured during machining, and compared with a theoretical value, and in dependance on the difference determined by this comparison, the feeds in the X and Z directions, determined by a control system from the cutting performance can be corrected. In a lathe 1, a workpiece 2 is machined by a tool 3, and the lathe is controlled by a numerical control system 6, in which the feeds in the Z and X directions are determined from the measured cutting performance. The spindle torque is measured, and multiplied by the spindle speed, and this cutting factor is compared with a theoretical cutting factor P zs  or P xs . The latter factor in many cases does not correspond to the maximum of which the machine is capable, due to vibrations. If the vibrations of the tool picked up from tool mounting 4 by an accelerometer or vibration measuring device 5, correspond in their amplitude A zi  and A xi , to theoretical factors A zs  and A xs , the output from amplifiers 11, 12, will be zero, and the value fed to feed controllers 7, 8, will correspond to the maximum value set up in potentiometers 9, 10. If the amplitude of vibration rises, the voltage across potentiometers 9, 10, and therefore the theoretical machining factor P xs , P zs , will drop. Instead of analysing the signal from tool 3, the signal from the spindle torque can be analysed.
