Abstract: 151,573. Fischer, E. G. June 10, 1920. Sounding - apparatus. -A sounding-tube of the pressure type with a spring valve for trapping the water is provided with a separate displacement rod and a separate co-operating scale bar suitably graduated. In the construction of Figs. 1 and 3 the tube 1 has a screw tightened cap 4 with a passage 8 for entry of the water and a spring valve 18 to trap the water. The displacement rod 35 has a sliding indicator 33, Fig. 6. In operation, on withdrawal of the tube, the tube is inverted, the screw 30 is released and the cap 4 taken out by swing- ing aside the retaining yoke 28. The displacement rod 31 is then inserted in the tube 1 far enough to displace the water to the top of the tube, the sliding indicator 33 being moved up simultaneously by the edge of the tube 1. The rod is now withdrawn and laid along the measuring bar 36, the height of the indicator 33 showing the depth. The scale is corrected to compensate for the strength of the valve spring while the valve seat recess 5 is made to compensate for the volume of the valve and other displacing parts. The scale bar has a Bat projecting end 37 for convenience in setting the displacement rod on it. To avoid entanglement and loss the apparatus is separate from the lead and is lashed to a rod a short distance from the bottom of the sounding-line.

Patent GB-603169-A (GB)
Title: Vehicle detector
IPC: G08G1/01
Filed: 1945-06-21
Abstract: 603,169. Radiolocation. AUTOMATIC SIGNAL CORPORATION. June 21, 1945, No. 15863. Convention date, May 17, 1944. [Class 40 (vii)] [Also in Groups XXX and XXXVIII] In a traffic detection system frequencymodulated ultra - high - frequency waves are directed along a traffic lane and waves reflected from a vehicle in the lane are combined with the transmitted waves to produce a beat frequency characteristic of the distance of the vehicle from the transmitter, the beat frequency being passed to a frequency selective device responsive to the frequency or frequency range characteristic of a vehicle at a predetermined distance or within a predetermined zone. As described, ultra-high-frequency waves are generated by a klystron or like tube 23, Fig. 2, comprising a heater 27, cathode 28, control electrode 29, focusing electrodes 31, 32, accelerating electrodes 38, 39 and a collecting electrode 50, the tube being jacketed in a cavity resonator 24. The ultra - high - frequency waves are velocity modulated by a 60-cycle A.C. power supply 49 applied to the accelerating voltage supply 42. The frequency-modulated waves are collected from the resonator 24 by a lead 22 and transmitted along a traffic lane by an antenna 21 via a wave-director 17. Reflected waves from a vehicle are received on the antenna 21 and combined with the transmitted waves in the resonator 24. The beat frequency, characteristic of the vehicle distance, is demodulated by a detector 68, amplified by an automatic volume control type amplifier 75, passed through tuned circuits 92, 87 and 96, 88 and the rectified output used to operate a relay or indicator-meter 99. The resonant frequency of the cavity resonator 24 is varied synchronously with the velocity modulation of the electron stream by means of a cam-operated plunger 57. A second synchronously driven cam 62 prevents beat frequency currents from reaching the indicator or like during the periods when the modulating wave is changing direction. By thus suppressing the peaks of the modulation, an approximately linear relation between vehicle distance and beat frequency is obtained and false beat frequencies which may occur around the positive and negative modulation peaks are suppressed. Switches 82, 85 in their upper position disconnect the filter circuits 92, 87 and 88, 96 and allow the indicator 99 to respond to frequencies within the pass-band of the amplifier 75 and hence to respond to the presence of a vehicle within a wide zone. To allow vehicles at several points or in several zones to be detected, the circuit subsequent to the amplifier 75 may be duplicated in parallel (Fig. 3, not shown). The speed and direction of travel of a vehicle travelling in a detection zone may be shown on a meter (Fig. 4, not shown) by measuring the rate of change of beat frequency and the direction of change respectively.

Title: Improvements in or relating to mechanical weft feeler mechanism for looms
IPC: D03D51/34
Filed: 1926-06-24
Abstract: 254,325. Maschinenfabrik R³ti vorm. C. Honegger. June 24, 1925, [Convention date]. Weft-replenishing mechanism.-Pointed and blunt weft-feeler needles 12, 13 are mounted on a holder 14 which is pivotally and adjustably mounted on a spring-pressed lever 10. The blunt nedles bears on the body of the weft, while the pointed needle is opposite the conical end thereof, so that it does not pierce the weft until the weft is nearly exhausted. The needles coact either with a slotted cop-case 4, Fig. 4, having internal winding-off, or an ordinary cop having longitudinal slots under the windings. The holder 14 also carries a dagger 15. The lever 10 is oscillated by the impact of the lay on its arm 24, while the dagger 15 is normally raised by the impact of the needle 13 on the weft. When the weft is substantially exhausted, the needle 12 pierces the remaining windings, and the dagger oscillates an arm 16 on a shaft 18 against a spring 20. A cam-plate 21 on the shaft 18 thereupon actuates an arm 22, 23 to stop the loom or to initiate weft-replenishment. The blunt needle may be dispensed with, while the pointed needle 12 and the dagger 15 may be made from a single piece of wire.

Abstract: 554,924. Spring wheels. BROWN, F. W. Dec. 22, 1941, Nos. 16468/41, 10241/42 and 17696/42. [Class 79 (i)] [Also in Group XXXIV] A spring wheel has a rim formed of segments 1 supported by levers 3 mounted on crank axles 49 and connected by links b, 6 to equalising levers 8 and quadrants 10 controlled by springs 19 arranged in the sides of the wheel. In the construction shown there are eight segments 1, each with its levers 3, 8, but each equalising lever 8 is connected by links 9 to the end of one quadrant and an intermediate part of an adjoining quadrant. The extent of each quadrant is indicated by arrows in Fig. 1. The equalising levers 8 are pivoted at one third of their length from one end to arms 7 pivoted at e to the wheel and connected to the links 6. The pivots of the levers 8 on the arms 7 are arranged alternately nearer the hub and nearer the rim; on those alternate levers having this pivot nearer the hub the inner and short link 9 is connected to the middle part of a quadrant 10 and the outer long two-part link 9 is connected to the rear end of the next quadrant, while on the other set of alternate levers the short link 9 is connected to the forward end of one quadrant and the long link is connected to the middle part of the next quadrant. The forward end of each quadrant is connected by a link 22 and crank-lever 21 to the corresponding spring 19, and the middle of the quadrant is connected by a crank lever 26 and a link 25 to the link 22. The coil of each spring 19 is of oval shape with thickened ends as shown in Fig. 9. The links 22 are normally held in the position shown in Fig. 3 by means of pivoted arms 23, bearing against pivoted stops 24; when these stops are turned aside the links 22 move to the dotted line position 27 so that the springs 19 give less support 50 the segments 1 and lengthen the ground contact of the wheel. The segments are connected together at their ends by short links 30, Fig. 4, and are connected by pivots to links 17 mounted on cranks 18 on the wheel. The levers 3 are connected by cranks 63 to the segments, by cranks 49 to the wheel hub or frame 70, and by links b, 6 to the arms 7, and are also interconnected by means of arms 2 pivoted at 16 and each connected by aspring s to a lever 3 of one segment and by a link 15 and link 6, b to the lever 3 of the next segment. The rim segments may be formed of corrugated spring steel and are covered by a continuous detachable tread comprising segmental steel bands 34 and an outer tread of steel or rubber secured thereto. The wheel is made asymmetrical as shown in Fig. 2, and the annular gap between the tread and a metal plate 46 is closed by a flexible cover 41. The segments 1 may be contracted together to allow the tread to be put on by disconnecting the links 30.
