Title: Process and apparatus for testing glass
IPC: G01N21/896
Filed: 1974-12-19
Abstract: 1526930 Detecting flaws in glass sheet BFG GLASSGROUP 16 Dec 1975 [19 Dec 1974] 54954/74 Heading G1A A moving sheet of glass 5 is scanned by a laser beam which in the absence of defects in the glass falls on a fixed spot 8 but which, when it encounters a defect, is deflected to one of the detectors 10-13, defects in the form of elongated bubbles being distinguished from others, e.g. pits or stones, by the proportion of deflected light pulses falling on detectors 10 and 11. A red beam (6329Š) of 1 to 2mm diameter from a helium-neon laser 1 is reflected by a prism 2, vibrating at 50Hz, and curved reflectors 4, 7 to detector unit 9 in which the said detectors 10-13 are photo-multiplier tubes. The prism 2 also deflects the image of a Gray coded scale 41 from projector 16 across a series of photoconductive detectors in a photo-electric coder 17 which sends signals representing different positions of the beam along a scan line 6 to a calculator 15. In the calculator, Fig. 4 (not shown), memories (42, 43, 44) keep count of the number of light pulses received by each pair of detectors at each position of the beam. A counter (51) and comparator (53) determine the number of forward traverses of the beam to cover each defect, which indicates the size of the defect, and initiate read-out of the memories to a calculator (48) which classifies the defect as a bubble or other type. The coder 17 also transmits signals representing the total number of transverses of the beam and instantaneous values of these signals representing the longitudinal positions of the defects are recorded in the calculator 15. A programming unit (58) may be connected to the output of the calculator (48) to control cutting of the glass while taking defects into account.

Title: Method of removing the Reaction Water and Inert Gases from Fuel-cell Batteries
IPC: H01M8/249
Filed: 1967-12-11
Abstract: 1,193,176. Discharge of inert gas and excess water from a fuel cell battery. VARTA A.G. 11 Dec., 1967 [14 Dec., 1966], No. 56263/67. Heading H1B. In a fuel cell battery using porous gasdiffusion electrodes, the gas spaces following the gas inlet in one or more electrodes of the same polarity are connected, in series or parallel, in a gas circulation system in which the gas is passed through a condenser to remove reaction water from the cells, and gas is removed from this circulation system and fed to the gas spaces of the remaining electrodes of that polarity, these spaces being connected in series, gas being discharged from the last space when the electrical output of the last cell falls below a predetermined level owing to the accumulation of inert gas, so expelling the inert gas from the battery. In the Figure, fresh gas enters the cycle at 1, whence it passes through the spaces 5, pump 3, and condenser 4 back to 1, some being withdrawn at 2 and fed to spaces 6 and 7, where gas in space 7 may be discharged through valve 8. The second set of cells may be electrically connected in series, each cell having the same current and the output drop of the last cell being a potential drop. In nickel-containing hydrogen diffusion electrodes the forced current in the last cell may lead to formation of inert nickel hydroxide; this may be avoided by connecting the last 2 cells in parallel, resulting in constant potentials and a drop in current. Examples use a 17-cell oxyhydrogen battery, having carbonyl nickel double layer electrodes with Raney Ni (H 2 ) and Ag (O 2 ) catalysts. In Example 1 the O 2  spaces of the first 12 cells are connected in parallel in the gas cycle, and the remaining spaces in series in the second set. The voltages of the last two cells are fed to a telegraph relay, which operates a solenoid valve in the last cell, when these voltages differ by more than 50 mv. In Example 2, the O 2  spaces of the first set of 12 cells are connected in series in the circulating system and the H 2  spaces of the first 10 cells are incorporated in a similar system, the spaces of the second set, 5 cells on the O 2  side and 7 on the H 2  side, being used for inert gas discharge. The two gases flow countercurrent through the second set of cells, and the last 2 cells in the H 2  flow system are electrically connected in parallel, their current outputs being passed through coils on an iron core, in the air gap of which a Hall generator causes a magnetic valve to open when the current ratio exceeds 3:1.
Patent GB-563405-A (GB)
Abstract: 563,405. Variable-speed gearing. NORMANVILLE, E. J. DE. Feb. 6, 1943, No. 2001. [Class 80 (ii)] Means for controlling variable-speed gearing for road vehicles includes a cam m having both rotational and axial freedom of movement and adapted to actuate a valve or switch associated with the speed-changing mechanism., the cam being movable by the driver in one of its modes of freedom and by means responsive to the speed of the vehicle in its other mode of freedom. As shown, a four-speed gear a, such as described in Specification 558,525, is controlled hydraulically from a valve box b having valve stems c, d. The latter engage the cam m which is slidable on, and rotatably fixed to, a shaft h which can be moved to four different angular positions by a hand lever j. Cam m is moved against the action of a spring q by a solenoid r controlled by a speed governor 3. The electrical circuit includes electromagnetic switches 2, u, governor switches 7, z, an engine ignition switch y and a switch 6 controlled by axial movement of the cam m. The armature 12 of the switch 2 has a detent 15 engageable with a recess 16 in the extension 13 of the cam m. When the lever is in its first position, the first speed ratio will be operative. The second position of the lever j permits automatic change between first and second speed ratios. The third and fourth positions of the lever permit automatic change between the second and third ratios, and fourth and second ratios' respectively. Changing down from any speed ratio to a lower one in response to movements of the accelerator pedal beyond the normal full throttle position, is accomplished by a lever 20 moved by the pedal and having a pawl-and-ratchet connection 18, 19, with the shaft h. In a modification, the axial movement of the cam is under hand control and the rotary movement under automatic control.

Abstract: 1,215,308. Cables. E. O. BUTTS. 13 Dec., 1967 [23 Dec., 1966], No. 56565/67. Heading H1A. [Also in Division G1] Leaks in a buried pipeline are detected by a device, positioned beneath the line, which comprises two conductors separated by insulation which is destroyed by the liquid in the pipeline but is substantially impervious to other fluids in its working environment. The conductors are connected to a high voltage supply and alarm circuit which is therefore energized by short circuit of the conductors due to a leak. On detection of a leak the conductors are then connected to a fault detector, e.g. conventional telephone cable fault detector, to locate the position of the leak. The two conductors may be arranged one 14, Fig. 3, in a core of insulation 15 with the other 16 wrapped helically around the core. For detecting leakage of fuel oil or other hydrocarbon the insulation may be butyl rubber.
