Title: Transmitter arrangements
IPC: H03F1/52
Filed: 1971-05-07
Abstract: 1393245 Radio transmitting systems PLESSEY CO Ltd 21 July 1972 [7 May 1971] 13649/71 Heading H4L A transistorized transmitter amplifier 4 is protected from overload by a feedback circuit having fast and slow response channels 12, 13. A low-pass filter 5 connects the amplifier 4 to an antenna and tuning unit, and reflectometers 7, 8 detect the presence of reflected power due to mismatch of filter or antenna respectively. Such reflection presents the amplifier with a high V.S.W.R. load, and to prevent damage, a selector 11 acts in response to the larger of the two reflectometer outputs and feeds it to the fast response comparator 12 and the slow response comparator 13 wherein it is compared with preset levels 1, 2. The comparators control the gain of an r.y. amplifier driving the transmitter amplifier 4. In the event of an a.m. signal being applied to the r.f. amplifier and an excessive output voltage (16, Fig. 3, not shown), occurring due to mismatch of the filter or the antenna, the fast action comparator rapidly reduces the gain of r.f. amplifier 1. Due to the low time constant of comparator 1 however, it quickly follows the resulting drop in output to increase the gain, and flattening of the output signal occurs due to successive changes in the gain control signal (F7, Fig. 4, not shown). The slow response comparator, however, takes over in about 10 ms. (dotted line, Fig. 4), and linear amplification of the signal proceeds.

Title: Improvements in and relating to loom picking motions
IPC: D03D43/00
Filed: 1922-05-16
Abstract: 201,671. White, A. E., (Huyck & Sons, F. C.). May 16, 1922. Picking - motions; checking pickers; checking picking-sticks.- The operation of the picking-sticks is controlled by electromagnetic devices which render the picking- mechanism at one end of the lay inoperative when there is a shuttle in the shuttle-box at the opposite end of the lay. The invention is described with reference to looms for weaving exceptionally wide fabrics such as endless felts for paper-making machines and in which the picking-sticks are operated by spring action. As shown, each picking-stick 10 is connected by a strap 12 to a picker 14, and a roll 16 fixed to the guideway for the picker acts on the strap to limit the forward movement of the picking-stick. The arm 42 of a lever 26, 36, 42 mounted on the pivot of the picking-stick carries a link 44 adapted to move the picker into position for picking. When the lever is rocked in a counter-clockwise direction by a crank-operated link 56, a projection 28 on the lever engages a projection 30 on the picking-stick, to move the stick into position for picking, and a link 20 connected to the lever and to chains 22 tensions springs 24. The picking-stick is retained in retracted position against the action of the springs by a latch 32 engaged by a projection 34 on the stick. The latch carries a sliding pin 40 controlled by a solenoid 58 which is adapted to raise the pin out of the path of an adjustable tappet 38 on the lever 36 when there is a shuttle in the shuttle box at the opposite end of the lay. If no shuttle is in position for picking at the opposite end of the lay, the tappet 38 raises the latch 32 and allows the picking to take place. The circuit of each solenoid is completed when the shuttle at the opposite end of the lay engages a contact arm 72. A switch may be provided for energizing both solenoids simultaneously when it is required to suspend the picking. The invention may be applied to drop-box looms.

Trace materials that can be easily recognized by characteristic electron-capture-signals with an ionization gauge, are used to detect and identify fluids. Two such materials may be used together to provide readily distinguishable signals. This "labelling" is of particular use in detecting leaks and locating an interface between fluids (e. g. petrol and oil) being transported in sequence along a pipe. The fluids are sampled at intervals and passed through one or more chromatographic columns to the detector. The carrier gas is preferably argon with 10% methane or nitrogen. The detector comprises a simple ionisation chamber and may be pulsed to produce signals for controlling flowvalves or mixing pumps. Suitable labelling substances are polyhalogens. such as dichlorofluromethane and long chain halogens (several examples are given).
