Title: Improvements in and relating to gripper shuttle looms
Inventor: SCHILDE FRITZ
IPC: D03D47/00
Filed: 1964-12-23
Abstract: 1,091,409. Gripper shuttle looms. WEBSTUHIBAU GROSSENHAIN VEB. Dec. 23, 1964. No. 52262/64. Heading D1E. As a gripper shuttle emerges from the shed, it trips a clamp which then holds the weft end released from the shuttle until the shed changes. As shown in Fig. 1, a spring-loaded presser foot 11 is held clear of the warp by a latch 14 engaging under a shoulder 16; the shuttle has a cam surface 18 which raises an arm 17 to disengage the latch, whereupon the presser foot clamps the warp threads together with the weft thread against the shuttle race 19. Alternatively, the clamp may be held open by toggle links which collapse when the shuttle operates the arm 17. Other forms of clamp employ forks mounted above or below the slay to penetrate the warp and press the weft down on to the shuttle race or forward against the fell. As shown in Fig. 19, the clamp consists of a springy wire 11 normally, resting on a shoulder in a slotted plate 73, but which is pushed off the shoulder 'by the shuttle so as to drop to the bottom of the slot 74. In another form, a rotating brush swings down to penetrate the warp and push the weft against the fell. Instead of controlling the clamp mechanically, the shuttle may bridge contacts to energise an electromagnet to operate the clamp.

Title: Color television camera overload compensating system
IPC: H04N9/64
Filed: 1969-11-10
Abstract: 1280651 Colour television RCA CORPORATION 10 Nov 1969 [20 Nov 1968] 54925/69 Heading H4F In a colour television system employing a single vidicon camera tube 11, in combination with a spatial colour encoding filter 13 in which the luminance and primary colour signals are derived at terminals 23, 28 and 29, an overload compensating system is included to prevent erroneous colour difference signals having negative values being produced, since for high subject light intensities the amplitudes of the high frequency colour carrier waves decrease whereas the low frequency luminance signals continue to increase but only slightly. Thus for neutral area highlights of the subject when the camera tube becomes overloaded the colour difference signals would be negative instead of zero and thus be reproduced in the third primary colour. The overload compensating system utilizes the fact that the magnitude of output current at which the camera tube begins to overload is determined by the magnitude of the current in the electron beam. A voltage proportional to the electron beam current is developed across resistor 21 and is used as a threshold biasing voltage for the low frequency components of the luminance signal derived from filter 31, so that an amplified narrow bandwidth low frequency luminance signal is only produced at terminal 45 when the signal at terminal 32 is greater than the biasing voltage. This resulting correction signal is applied via a negative gain amplifier 46 and added 47 to the luminance signal at terminal 32, and the resulting signal is clipped at ground potential 48, 49 and subtracted from the primary colour signals to derive corrected output colour difference signals. In a second embodiment, Fig. 2, uncorrected colour difference signals are produced at terminals 33 and 34, and when the camera begins to overload the threshold device (44, Fig. 1) produces a voltage at terminal 45 which renders the collector-emitter current paths of switching transistors 61 and 62 conducting which short circuits the outputs of subtractors 56 and 57 thus preventing the development of incorrect colour difference signals at outputs 33 and 34.

Abstract: 1420702 Automobile window regulators ITT INDUSTRIES INC 6 Dec 1973 56515/73 Heading E2M An automobile window regulator which effects the sequential operation of two sliding window panels 18, 20 comprises two operating arms 44, 46 pivotally mounted at 38 which engage the windows via rollers 45, 47, two cam levers 50, 52 pivotally mounted at 48 which are linked to the arms by members 88, 90, and a manually or electrically actuated gear sector 42 which is pivotally mounted at 38 and which carries cam followers 60, 68 to engage the cam levers 50, 52. Each cam lever has an arcuate portion 80, 82 around which the respective cam follower 60, 68 can move freely and a straight portion 76, 84 in which the follower engages to effect movement of the cam lever. Fig. 1 shows vent 18 and primary 20 window panels in the fully up position. On rotation of the gear sector 42 in a clockwise direction via a drive pinion mounted within a housing 36 follower 68 rides around arcuate portion 82 and the primary panel 20 remains up; at the same time follower 60 moves the arm 50 as it moves up in portion 76 to lower the vent panel. Fig. 3 shows the vent panel 18 fully down and the primary panel 20 still fully up. At this point follower 68 enters straight portion 84 and will henceforth move the arm 52 to lower the primary panel 20, while the follower 60 rides freely along portion 80 having no further effect on the movement of the vent panel 18. Fig. 4 shows both panels fully down and upon actuation of the gear sector in the opposite direction the process described above will be reversed - the primary panel will be fully raised before the vent panel begins to move.
