Title: Method and apparatus for automatic baseline and standard calibration of automatic multichannel sequentially operable fluid sample supply treatment and analysis means
IPC: G01N21/27
Filed: 1971-04-19
Abstract: 1342688 Photo-electric analysis TECHNICON INSTRUMENTS CORP 19 April 1971 [13 March 1970] 23896/71 Heading G1A In an arrangement for the analysis of samples and recording of results means are included whereby the calibration at zero and at a standard value is checked and any error signal produced during the check is applied to effect the necessary respective correction. In the embodiment described, a sample withdrawn from one of a sequence of tubes is divided for a succession of tests for different constituents under programme control and samples of standard liquid and distilled water are provided at a number of calibrating positions on the turntable at which positions the apparatus readings are compared with preset voltages corresponding to the standard value and the recorder base line for each of the tests. Error signals are applied by a comparator 128, Fig. 2, to a counter 130 and are arranged to effect the necessary adjustment of the measurement signal by stepping binary ladder-networks 42, 78 through their respective ladder switches 44, 80 and updating the signal stored in the shift register buffer arrangement 54, 56 for the subsequent respective tests. Switch 48 provides sensitivity control by connecting either of reference voltage sources ER1 or ER2. Reference voltage potentiometers 150 and manual calibration potentiometers 72 are provided for each of the separate constituent tests and the apparatus is controlled to effect calibration by the detection of the presence of the reference samples at the "calibration" position, by timers 176, 180 and by the switch controlled logic circuit 162. Meter 190 indicates the order of the error, and additional alarms may be provided together with channel indicating lamps. Colorimeter analysis of blood samples is exemplified.

Title: Blow-moulded plastics containers
IPC: B65D1/02
Filed: 1973-05-18
Abstract: 1462192 Waste bins A F GROUNDS 24 July 1974 [18 May 1973] 23941/73 Heading A4A [Also in Divisions B5 and B8] A container blow-moulded in one piece from plastics, e.g. L.D. polyethylene, comprises at least two adjacent annular regions which, on axial compression of the container, snap over from a first stable condition into a second stable condition in which the two regions are closer together to facilitate storage of the container when empty. The container may be a rubbish bin, rainwater vat, or a container or container liner for powders or liquid. However, as shown, the container is in the form of a moneybox moulded with a slot 9 at one end, Fig. 2 (not shown), in a mould, Fig. 3 (not shown), and the annular regions are constituted by ridges 1-7 producing a corrugated side wall form, the dimensions and thickness of which are such that on axial compression the ridges snap into a second stable form in which the crest of one ridge encircles the flank of an adjacent ridge. The diameters of the ridge crests may increase and then decrease, or decrease, or as shown decrease and then increase from one end of the container to the other. The container is provided with a carrying string 12, and the top 8 may be cut completely or nearly completely off to open the container and/or form a separate detachable or hinged lid, Fig. 5 (not shown). In another arrangement (not shown), a container has alternating relatively thick and thin annular regions which snap into a collapsed bellows-like stable state when axially compressed.

Abstract: 1516542 Cassette tape apparatus TELETYPE CORP 4 June 1975 [14 June 1974] 24080/75 Heading G5R Pivoting of a cassette-holding cradle 20 from a loading position, Fig. 2, to an operative position, Fig. 3 (not shown), effects movement of a light sensor 110, (118), Fig. 5 (not shown), from a withdrawn position to an operative position located in one of the usual capstan apertures (136), Fig. 3, of the twin-reel magnetic tape cassette for detecting the transparent tape leaders in co-operation with a light source 122 on cradle 20. A cassette (13), Fig. 3, inserted into cradle 20 is urged by leaf springs 74 against a back wall 60 thereof, further leaf springs 56 biasing cradle 20 toward its loading position. On pivoting of the cradle 20 to the record/ playback position, pins 62 on stationary plate 18 position the cassette, whereafter a pin 109 on cradle 20 pivots a lever 94 against bias of a spring 107 whereby the bifurcated lower end 96 of lever 94 slides light-sensor-containing casing 110 in stationary sleeve 108 so that casing 110 enters a capstan aperture (136), Fig. 3, in cassette (13) to locate the light sensor opposite the lamp 122 on cradle 20. The cassette (13) and cradle 20 are held in the operative position by engagement of cassette (13) with a notch of a latch 90 which has a camming surface 91 engageable by cassette (13) when moving to the operative position. Latch 90 is carried by a U-shaped member 86 fixed to a flat spring 82 and biased by a spring 92 towards a front one of two adjustable position-limit screws 85. A switch 89 senses the presence of a cassette (13) in the operative position of cradle 20. The tape transport has no capstan, drive pulleys (32), (34), Fig. 1, being driven in opposite directions by belts (28), (38) and drivingly engaged one at a time via electromagnetic clutches (40), (42) with take-up and supply reel drive spindles (45), (47) respectively. The magnetic head (64) may be mounted in the manner described in Application No. 24081/75.

Abstract: 942,142. Coaxial cables. NORTH WESTERN SPECIALITIES Ltd. July 27, 1961 [July 11, 1960], No. 24099/60. Heading H1A. A coaxial cable, one embodiment of which is shown in Fig. 1, utilizes a metal tape T for one, or the, outer conductor. This tape T is wrapped around the dielectric so that its edges either overlap or are closely adjacent and is protected by a covering 11 which is preferably of a conducting material of high specific resistivity. Adjacent to the tape and in electrical contact with it is a conducting open mesh braid 10 which maintains the connection if the tape is damaged. This braid 10 may be either above or below the tape but is preferably above it. One or more extra conductors may be added by means of braids B which may be in contact with, or insulated from, the tape T (Figs. 3, 4). It is stated that the metal tape may be shaped around the inner conductor and insulant as the latter emerges from the die of an extrusion machine.

In an electrical error-actuated closed-loop process control system the sensitivity of the control system to fluctuations is automatically reduced when the error is less than a value corresponding to substantially three times the standard deviation of the noise signals in the system. In Fig.2, a number of variables of a process 10 are measured and interrelated in accordance with predetermined control laws by an analogue or digital computer 12 outputs of which control the process through control devices such as 14. As shown, the difference between one computer output signal and a signal from a follow-up transducer 16, representing the position of control device 14, is periodically sampled at 22 and applied as an error signal through a variable gain, damping, phase-shifting, amplifying, averaging and integrating system 20 to correct the position of control device 14. The error output of sampling device 22 is compared at 34 with a signal from an adjustable source 32 which is set to correspond in magnitude with three times the standard deviation of the noise level in the system. Then, whenever the error exceeds this level, the output of comparator 34 varies the gain of system 20.
