Title: Test system device with identification code
IPC: G01N21/78
Filed: 1974-12-04
Abstract: 1461319 Test device with identification code MILES LABORATORIES Inc 4 Dec 1974 [21 Jan 1974] 52462/74 Heading G1B A test device for determination of a chemical  constituent in a fluid and for use with an instrument responsive to code means on the device comprises a carrier member 16 which may be of transparent plastics, on the carrier member at least one test reagent reactable with a specific constituent in the fluid, the test reagent in the embodiment being  in the form of a paper strip 18a, 18b, 18c impregnated with the reagent(s), and code means 17 on the carrier at a predetermined location on the device and in a predetermined spaced relation with respect to the at least one test reagent for indicating to a code-means responsive instrument, the particular test reagent(s) on the carrier member. In use in the apparatus shown, the device after being brought into contact with the fluid being tested is placed on transparent table 43 and moved by actuator 45 to make carrier member 16 pass between light from source 37, fibre optics 40 and photo-sensitive element 41. Transmission of light through the carrier member to element 41 is interrupted by code means 17 in the form of an opaque sheet on the carrier member or by one of the reacted test reagent areas 18a, &c. and the test device is identified by the instrument by this detection of the relative dispositions of the code means and the reagent(s). When a test reagent is detected, photo-sensitive device 38 becomes operable to detect light reflected from the test reagent area for determination of the amount of reacted constituent sought, and the test result and device identification data are fed to printer 33. Examples refer to test reagents for determination of protein and of glucose.

The ceramics can be prepared from raw materials which mainly consist of clay, loam, marl, clay slate, kaolin, charnotte, silica and felspar. The hardening can be carried out at 600‹ C. with partial pressures of about 2 atmospheres steam and about 1 atmosphere carbon dioxide in a chamber having valves to regulate the superatmospheric pressure therein.

Title: Apparatus for analysing complex waveforms
Inventor: SCARR ROBERT WALTER ALISTER
IPC: G10L25/00
Filed: 1966-11-30
Abstract: 1,139,711. Speech recognition. STANDARD TELEPHONES & CABLES Ltd. 30 Nov., 1966, No. 53636/66. Heading G4R. In apparatus for analysing a complex waveform, the waveform is fed via a band-pass filter to a zero-crossing detector and a peak amplitude detector, the time elapsed between two successive zero crossings bearing a specific relationship to the detection of a peak amplitude being obtained. In Fig. 2, a speech waveform is band-pass filtered at 7 before passing to a peak amplitude detector 8 and zero-crossing detector 9. The first peak, detected at 8, switches on a counter 11 so that it counts zero-crossings, detected at 9. The first zero-crossing also starts an integrator 14, 15 which is read out via AND gate 16 to a sample and hold circuit 17 on a count (at 11) of two. Thus circuit 17 stores a voltage proportional to the time elapsed between the first and second zero-crossings following the first peak. Circuit 17 may feed an oscilloscope and is reset at the start of the next voicing cycle, or when threshold circuit 18 indicates an absence of signal. In Fig. 4, four circuits 20, 21, 22, 23 each as above, the filters having the pass-bands shown, are used to recognize the presence of the first and second formants. If the outputs of circuits 20 21, 22, 23 exceed respective thresholds, the ratio of the thresholds being fixed but the actual magnitudes depending on a master threshold circuit 24 responsive to the speech input, "threshold yes" outputs are energized. Units 25,27,29,31,32 and AND gates (some inhibitory) and units 26, 28 are OR gates. Coincidence unit 30 produces an output if its inputs are unequal. Fig. 4 is otherwise self-explanatory.

Title: Bright anodizable aluminium-magnesium sheet and production thereof
Inventor: PRYOR MICHAEL JOSEPH
IPC: C22C21/06
Filed: 1965-12-17
Abstract: A bright anodizable aluminium-magnesium sheet comprising at least one surface layer, preferable 10% of sheet thickness, having Mg in the form of a fine precipitate of at least one intermetallic compound uniformly dispersed and the remainder of the thickness having a coarser precipitate of the compound dispersed, is produced by heating a sheet of Al-Mg alloy, e.g. to 750-950 DEG  F. for an alloy containing 0.2-3.2% Mg and less than 0.4% Fe + Si, to dissolve the compound into solid solution, establishing a thermal gradient through the sheet thickness e.g. by cooling one or both surface layers to 450-700 DEG  F., and precipitating the compound(s) through the joint action of the thermal gradient and mechanical deformation e.g. by warm pressure rolling immediately after surface cooling while the thermal gradient is 75-350 DEG  F. With alloys containing 0.2-1.8% Mg, a fine precipitate of Mg2 Si only occurs; with alloys containing 2-3.2% Mg, a fine precipitate of Mg2 Al3 also occurs.  The surface cooling may be effected by air jets located adjacent hot rolls or by oil or water cooling.

Title: Apparatus for electronic exposure control in photographic cameras
Inventor: REIMANN HUBERTUS
IPC: G03B7/083
Filed: 1965-12-22
Abstract: 1,086,300. Electronic exposure control. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Dec.22, 1965, No.54350/65. Heading G2A. A camera has an electronic circuit arrangement for control of both the exposure time and a delayed action, the latter of which may or may not be used, as required. The circuit is built round an oscillator transistor 1, whose base biasing voltage can be adjusted by a variable resistance 13. A repeater in the collector circuit of the transistor has one secondary 2 coupled to a charging condenser 4 in series with resistances 7, 8, 9, 10 which determine the exposure time (and which may be replaced by a photo-conductive cell). The other secondary forms the input of a switching stage, switch 22 being open if delayed action is not required. If it is required, the switch is closed by the movement of the shutter release. At the end of the delayed action, the timing circuit is automatically switched over to its exposure time controlling function. This change-over is operated by a mechanical element in the camera, such as the mirror drive of a reflex camera.

Abstract: 1,158,009. Pipe joints. IMPERIAL-EASTMAN CORP. 21 Dec., 1966 [23 Dec., 1965], No. 57116/66. Heading F2G. A tube T is sealingly coupled to an exteriorly threaded union body 10 on tightening a cooperating nut 12 by a resilient, e.g. rubber, frusto-conical sleeve 13 which is deformably compressed between an arcuate camming end surface 35 on the fitting and an internal shoulder 27 on the nut. The inner end 32 and intermediate portion 33 of the sleeve deform to a first V-shaped fold, the sleeve inner end engaging between the camming end surface and the tube to provide a seal there between and the intermediate portion sealingly engaging the camming end surface axially outwardly of the engagement of the sleeve inner end with said camming surface. The outer end 31 of the sleeve is also deformed inwardly to define with the intermediate sleeve portion a second V- shaped fold providing additional sealing. As shown, deformation of sleeve produces radial constriction of the tube wall. The larger end of the sleeve is of slightly larger diameter than the annular surface 34 of the nut so that the sleeve may be yieldingly mounted therein.
