Title: Method and apparatus for detecting faults in fabric
IPC: D06H3/08
Filed: 1974-10-24
Abstract: 1462235 Detecting flaws in moving sheet material LEVI STRAUSS & CO 24 Oct 1974 [24 Oct 1973] 46080/74 Heading G1A Apparatus for detecting flaws in moving sheet material comprises light source 15 from which light is directed (a) through sheet 22,to sensor 46, (b) at an acute angle of incidence on to sheet 22 with sensor 26 responsive to light reflected (c) at grazing incidence on to sheet 22 with sensor 42 responsive to light grazing the sheet. The method of doing this is claimed together with individually integrating the signals from the three sensors and adding the integrated signals. The signals vary with thickness, colour and texture variations as textural obstructions. A number of the above apparatuses are arranged side by side across sheet 22. Housing 10, the interior of which is painted white, has partitions 12, 14, 16 and 18. Sheet 22 is supported by low friction support bed 20 of chromiumplated polished steel. The source may be a 6V bulb run at 3V. Sensor 26 receives light on path 28 by reflection from an area about 0.04 inches long at high point 24. Sensor 42 receives light reflected and diffused at 34 and 38. Light shield 50, pivoted at 52, is moved by lever arm 54 to adjust slit 56 formed with shield 48. In Fig. 2 output 66 becomes energized when the potential at junction 60 exceeds +v due to a high value of reflected light and output 74 is energized when junction 60 becomes more negative than -v due to a low value of light. Sensor 46 has a similar circuit giving two outputs and sensor 42 only has the amplifier 58 giving one output, making altogether five outputs which are connected to the inputs of the utiliza-  tion circuit Fig. 3 (not shown), in which each input is connected via an integrator and a circuit multiplying the signal by a weighting factor to summation circuit (84), feeding via analogue to digital converter (86), comparator (88), supplied with a reference digital value at (90). Indication or recorder (92) shows when the value at (90) is exceeded, and may mark the place of the flaw on sheet 22. In Fig. 4 (not shown) is a circuit measuring the difference between the output of the H sensors of a given apparatus and the average of a number of such outputs. This eliminates the background due to fabric pattern.

As shown, the switch also comprises a fixed contact 57 for connection to an alternative source of power, a fixed contact 60 for connection to the transfer switch and moving contact 159 for connecting fixed contacts 57, 60, moving contact 160 also being able to connect load contact 58 to the alternative power source contact 57. Moving contacts 140, 159 are connected by links 174, 177 to disc 167 on spindle 163, rotation of disc 167 moving contacts 140, 159. Moving contact 160 is on a spindle which carries a star-wheel 179 located in position by pins 190, 191 on members 188, 189 urged together by spring 192, and also carries a plate 181 carrying a pin 185 on which is pivoted a link 183 guided at its upper end between fixed pins 186, 187, and carrying a pin 184. In the switch position shown in Fig. 6, pin 184 rests on the periphery of disc 167 and as a result, moving contact 160 cannot be moved. Moving contacts 140, 159 can be moved by rotating spindle 163 and disc 167, and when they are moved to the closed position engaging fixed contacts 56, 57, a slot 176 in disc 167 cones opposite pin 184 so that moving contact 160 can be moved to engage fixed contacts 64, or 57, pin 184 entering slot 176 to permit movement of contact 160, as in Fig. 9 (not shown). Once pin 184 is in slot 176, disc 167 cannot be rotated so that contacts 140, 159 can only be moved if contact 160 engages either supply contact 56 or the alternative power source contact 57, pin 184 being out of slot 176 in both of those positions. Moving contacts 140, 159, 160 each consists of two plates urged together by springs to grip their respective fixed contacts.

Filed: 1968-10-02
Abstract: 1,207,027. Hydraulic relief valve. DANFOSS A.S. Oct. 2, 1968 [Oct.17, 1967], No.46805/68. Heading F1P. A double acting piston device (13) Fig.1 (not shown) has two parallel one way valves (18 and 19, 20 and 21) across each side and a fluid return pipe one operative to relieve excess pressure to this pipe, the other allowing fluid to flow into the cylinder if cavitation take place. An additional valve (22, 23, 24) vents the cylinder only if the combined pressure in each end exceeds a maximum set lower than the over pressure relief limit. A combination drive is symmetrically arranged, the pressure pipes from each side of the cylinder communicating at 15, 16 respectively and the return pipe to the reservoir joining at 17. On excess pressure piston 27 or 28 respectively retracts to a stop 29 and further pressure causes valve 32 or 33 to open against a strong spring 34 or 35. Low-pressure causes ball 42 or 43 to lift off its seating and admit fluid to the cylinder. If the combined pressure of the two parts of the cylinders exceeds the set maximum, both pistons 27, 28 will retract and eventually push rod 49 will engage balls 42, 43 and push them off their seating thus venting the system to the return pipe.
