Title: Temperature and respiration detector
IPC: A61B5/332
Filed: 1974-10-24
Abstract: 1483410 Oral probe for temperature, respiration and pulse measurement UNITED STATES SURGICAL CORP 24 Oct 1974 [25 Oct 1973] 46091/74 Headings A5R and ASK [Also in Division G1] In a disposable oral probe 12 for sensing oral temperature, respiration rate and pulse rate, a plurality of thermocouples are positioned on the probe. One set of "hot junctions" are adjacent a recess at one end of the probe (for measuring oral temperature). Another set of "hot junctions" 18 are positioned over an aperture 85 so as to be in the airflow from the nose (for measuring the respiration rate). The first set of junctions 16 also act as an "electrode" with a further electrode 32, Fig. 6, on the base of a hand held corrector housing 26 (for contact with the patient's left thumb) to provide information about the electrical activity of the patient's heart. The oral probe 12 is spring releasably secured in housing 26 by means of a spring 58 which normally causes a pivot element 42 to press down on one end 22 of the probe 12. The probe 12 is released by squeezing the "back" part of the housing 26. The "cold" junctions 17, 19 of the thermocouples are located at the end 22 and are in close physical and thermal contact with a resistance thermometer 24 underneath the pivot element 42. The resistance thermometer 24 is connected into a bridge circuit 30, Fig. 8, as shown, to compensate for temperature variations in the outputs of the thermocouples 16, 17 and 18, 19. The voltage output of the thermocouple 16, 17 is fed via a temperature amplifier 130 to a temperature display 132. The voltage outputs of the thermocouples 18- 19 are fed via an amplifier 142, a trigger circuit 144 and a rate circuit 146 to a respiration rate display 148. The E.C.G. voltage between the hot junctions 19, 16 and the thumb electrode 32 is fed via an amplifier 134, a trigger circuit 136, and a rate circuit 138 to a pulse rate display 140. The resistance thermometer 24 may have a bi-filar spiral configuration (Fig. 5 not shown). There may be 3-10 hot junctions for the temperature feature and the thermocouples which form a thermopile may consist of wire that has been wound longitudinally around the probe which is plated with a dissimilar metal over part of its length to provide the junctions.

Title: Apparatus for testing bottles
IPC: G01N3/12
Filed: 1972-10-06
Abstract: 1394188 Testing bottles MITSUBISHI JUKOGYO KK 6 Oct 1972 [19 Oct 1971 20 Oct 1971] 46321/72 Heading G1S Bottles a, Fig. 4, previously filled with water from sprays and then passed via a screw fed star wheel, Fig. 3 (not shown), to a turntable 13, have their mouths closed by spring arms 18a operated by rollers R running on a stationary cam disk 20. The table carries a plurality of testing cylinders 21 operating spring urged piston rods 22 and test heads 23, Fig. 6, from a compressed air supply 42 fed from a pneumatic circuit. Fig. 7 (not shown) which supplies air both to the cylinder control and also to the testing heads. In operation, and considering the passage of a single bottle through the apparatus, the water filled bottle is fed on to the table and covered by a guard 61 which directs any broken pieces on to a tray 62. The arm 18a is then lowered by the cam disk 20 and roller R to hold the bottle down. Further rotation of the table causes a cam 46, Fig. 4, to open a main control valve 49 and connect air valves so that the head 23 is moved downwardly to insert the piston end 28' into the bottle and cause water therein to overflow. The sealing member 35, Fig. 6, at the bottom of the head is then brought down on to the top of the bottle mouth to seal it. Another rotation step of the table causes a cam 32 to operate valves 51 & 55 so that air pressure is supplied to the top of the enlarged head 28 of the piston to add to the sealing pressure and cause the end 28' to enter further into the bottle and thus compress the water therein to test the bottle structure. If the bottle withstands the test it is moved around, the air pressure is cut off and the piston and seal removed so as to release the bottle to another conveyor. If the bottle is chipped on the mouth then a test piston of the kind shown in Fig. 10 may be employed, so that when a test pressure cannot be built up in the bottle because of the chip, the piston 28 moves further down until a reduced shank portion 70, not normally uncovered, communicates with cross air passages 71, 72 to energize a bottle reject piston 75.

Abstract: 1281377 Induction furnaces ALLMANNA SVENSKA ELEKTRISKA AB 29 Sept 1969 [30 Sept 1968 16 June 1969] 47781/69 Heading F4B [Also in Divisions H2 and H5] The direction and rate of flow of a metal or alloy melt in the channels 115, 116, 117, 118 of an inductor unit of an induction heating furnace are regulated by establishing a magnetic flux B perpendicularly across the melt flow using a D.C. or single phase A.C. fed electromagnet, which flux interacts with the secondary currents j induced in the melt flow by one or more primary heating coils 113, 114, to produce a force F on the melt flow. Relative variation of the magnetic flux or the secondary currents, varies the force produced, whilst alteration of the relative directions of the flux and secondary current flows, alters the direction of the resultant force F. In modifications (Figs. 1 and 7, not shown) the force F may accelerate, pervent or restrict melt flow through a tap-hole communicating with the bottom channel, the force being automatically varied in response to a signal from a weighing device or a level indicator in a melt receiving ladle (not shown). A safety valve (not shown) may close off the taphole on failure of the electric current supply, or a reserve current source may be included in the supply circuit. The furnace may be used to vacuum degas a melt.

Title: Improvements relating to electrical inverter apparatus

IPC: H02M7/53846
Filed: 1967-10-27
Abstract: 1,204,682. Protecting inverters; supply systems for fluorescent lamps. STONE-PLATT CRAWLEY Ltd. 7 Oct., 1968 [27 Oct., 1967], No. 48960/67. Headings H2F and H2H. A transistorized inverter includes a circuit 10 for interrupting a D.C. power supply for the duration of surges or slight over-voltages on the input line, a further circuit 11 for interrupting the D.C. supply in the event of severe overvoltages and a third circuit 12 for interrupting the D.C. supply for a predetermined time in the event of excess current being taken by the inverter. As shown, a push-pull oscillator 2, the frequency of which is determined by the tuned circuit 13, 14, is coupled via transformer 3 to an amplifier 4 which drives the banks of output transistors J5, J6 which drive an output transformer 7. Resistor 15 ensures that one of the transistor banks J5, J6 always switches off before the other switches on. Diodes 18 and Zener diodes 19 protect the output transistors against over-voltages due to the reactance of the fluorescent lighting load 8. Over-voltage protection.-In the event of slight increase in D.C. input voltage, transistor J7 of a Schmitt trigger becomes turned .on, turning off transistors J8 ... J12 which disconnect the supply to the amplifier 4 and thus remove the drive from the output stage 6. This continues until the input voltage falls below a predetermined level when the supply becomes restored. A severe over-voltage causes Zener diode 28 to break down, turning on thyristor 27 and opening fuse 30. Over-current protection.-The D.C. input current to the output stage 6 is monitored by resistor 31. If the input current becomes excessive, the voltage of the junction of resistors 33 and 34 will rise, turning on transistor J15 of a Schmitt trigger so that transistors J11... 14 becomes turned off and interrupts the supply to the amplifier 4. Transistor J17 is also turned on so as to provide a charging path via resistors 35, 36 and 38 for capacitor 36. When capacitor 36 has charged sufficiently, unijunction transistor J16 will conduct, turning on transistor J18 which, in turn, turns off transistor J15 and J17 so that transistors J11 . . . J14 are turned on and restore the supply. If the over-current condition still persists, the switching sequence will be repeated and the apparatus will continue to cycle on and off until the condition has been rectified. Lighting railway vehicles.-The invention is applicable to fluorescent lighting of a railway vehicle, from a battery charged by an axledriven generator, the inverter being mounted in a well ventilated cupboard or in a sealed box under the vehicle frame.
