Title: Dynamic multistation photometric analyzer for serological testing
IPC: G01N21/07
Filed: 1973-06-25
Abstract: 1405694 Photometry sample holders UNITED STATES ATOMIC ENERGY COMMISSION 25 June 1973 [2 Aug 1972] 30108/73 Heading G2J A photometric analyzer of the multistation, rotary type has a rotor I comprising a circular array of loading cavities 7 within a circular array of sample analysis cuvettes 8, each cavity 7 being in radial alignment with a cuvette 8 and separated therefrom by a sloping barrier 12 to prevent transfer of liquid from 7 to 8 when the rotor 1 is static but permitting centrifugal transfer. Barrier 12 has a passageway 17 to one side at the top to assist mixing. A drain passageway 9 communicates with the radial extremity of each cuvette 8 and a central dynamic loading and distribution chamber 15 is provided which adjoins the radially inner edges of the loading cavities 7 and has a serrated periphery to cause equal distribution. The cavities 7 and cuvettes 8 may be formed in a PTFE disc 5 held between transparent plates 3, 4 in a steel body 2. In use, samples e.g. of blood are loaded via opening 19 in upper plate 4 or by using a transfer disc. The samples are then centrifugrally transferred to the cuvettes 8 to which access is afforded by recesses 13 in plate 4. The particulates of the samples are thus spread in a thin layer over the outer wall of cuvettes 8 and may be mixed with a diluent stream. After another centrifugal separation, the overlaying liquid may be removed by applying vacuum to drainline 9 or aperture 19 may be sealed and gas pressure applied to the central chamber. Optical Details: Agglomeration is measured by observing rate of sedimentation of resuspended particles using usual photometric techniques. Two radially spaced slit sources may be used to measure the time for the sedimenting boundary to pass from one radius to another. Agglomeration, lysis, fluorescence and radio-activity can be observed with appropriate detectors while supernatant liquid properties such as fluorescence, radio-activity and light absorbency can also be observed.

Abstract: 923,548. Valve sawtooth circuits. BUSH & RANK CINTEL Ltd. Nov. 4, 1960 [Sept. 4, 1959], No. 30240/59. Class 40 (6). In a deflection circuit for a cathode-ray tube the deflection coil is coupled via a directcurrent path to the output stage, the deflection is linearized by feedback from a resistor in series with the deflection coil, a compensating device being connected between the power supply and the feedback circuit to minimise variations in feedback voltage due to variation in power supply voltage. As shown, valves 2, 3 form a differential amplifier controlled by a sawtooth waveform at terminal 1 and the linearizing feedback from resistor 15 fed via circuit 16 to the grid of valve 3. The combined waveform at the anode of valve 3 is fed to the deflection coils 14 via a single-ended push-pull stage comprising valves 8, 9. Any variation in power supply voltage is inverted by the cathodecoupled stage 18, 19 so that it counteracts the variation in the voltage fed back from resistor 15. Part of the deflection waveform relating to the other axis of the cathode-ray tube may be applied to terminal 30 to correct quadrature distortion as described in Specification 899,097.

Title: Improvements relating to electrical resistance welding
Inventor: GRISWOLD LEE M
IPC: B23K11/25
Filed: 1967-07-03
Abstract: 1,162,915. Welding by pressure. DIGITAL SENSORS Inc. 3 July, 1967, No. 30583/67. Heading B3R. [Also in Division H2] In electrical resistance welding the resistance between the welding electrodes is monitored while welding pressure is applied between the electrodes to the workpieces, the welding pressure is monitored to determine if it is or is not less than a predetermined value and welding current is passed only when the monitored resistance does not exceed a pre-determined value and the monitored pressure is not less than the pre-determined value. An A.C. voltage source 12 is connected across terminals 10, 11, the terminal 10 is connected via an on/off switch 14 to a terminal 8, and a checking circuit is connected across the terminals 8, 11. The checking circuit includes a transformer 9, one side of whose secondary 9B is connected to one welding electrode 4 and the other side through a normally closed relay 20A to the other electrode 5, and a cathode ray oscilloscope 1 having its vertical deflection terminals connected across the electrodes 4, 5. When the electrodes are open full secondary voltage occurs across them and the oscilloscope shows a full height vertical trace when the electrodes are pressed on to the workpieces a trace of smaller vertical height is shown, the optimum being a square trace. A satisfactory trace for the completed weld has a rectangular shape of width greater than height. A firing and welding circuit 25 has its output terminals connected to the electrodes 4, 5 and its input terminals in a series circuit including two normally open relay switches 15G, 16D, the relay coil 15 being energized when a manually operated switch 26 is closed and the relay coil 16 being energized when a switch 17 sensitive to the pressure exerted between the electrodes is closed at a preset pressure. The coil 16 is connected to the terminals 8, 11 via the switch 17 and a buzzer 28 is provided in parallel with the coil 16. The coil 15 is connected to terminal 11 and via switch 26 and normally open and normally closed respectively relay switches 15A, 16A to terminal 8. The relay coil 20 is connected to terminal 11 and via normally open relay switch 15D to terminal 8. In operation the workpieces are arranged between the electrodes and pressure applied until the buzzer sounds indicating closure of switch 17 which energizes coil 16 to open switch 16A and prevent energization of coil 15. If the oscilloscope display is appropriate the electrode pressure is removed, switch 17 opens and relay switch 16A closes, the switch 26 is closed to energize coil 15 to close switches 15A, 15D, 15G and switch 15A holds the relay coil 15 energized. The coil 20 is energized to open switch 20A and isolate the transformer 9. The preset pressure is applied by the electrodes causing switch 17 to close and then via contacts 15G and 16D an input is supplied to the circuit 25 which supplies a current to the electrodes. After welding the operator checks the condition of the weld by the oscilloscope trace.

Title: Improved apparatus for generating steam
IPC: F22D1/08
Filed: 1923-03-24
Abstract: 208,158. Bell, J. E. July 1, 1922, [Convention date]. Feed - water, heating. - In a boiler feed-water heater having banks of horizontal tubes through which the water flows downwards, and over which the hot gases flow upwards, the number of tube paths is such that the velocity of the water flow during the normal operation of the boiler is above that which permits of the equalization of the water temperature throughout the heater by convection. The tubes D<1> of a feed-heater placed in a flue above a water-tube boiler are arranged in staggered rows, and are connected to junction boxes D" and supported at their centres by a plate D<5>. By altering the tube connections, the velocity of water flow is so determined as to give a definite graduation of temperature increasing towards the bottom of the heater. Internal corrosion is thus confined to two or three rows of tubes in which the water is at about 180‹. A vertical flue passage D<12> between the tubes is fitted with dampers E, which are opened to allow part of the gases to pass directly to the fan casing H when the load on the boiler is high. The casing around the heater is packed with heat insulating material. Castiron rings are shrunk on the heater tubes. In a modification, two vertical banks of tubes connected to a common header are arranged in parallel flues so connected that the hot gases pass upwardly through one bank and downwardly through the other bank. Specifications 14868/96 and 22663/03, [both in Class 123, Steam generators], 24162/14 and 200,060 are referred to.
