Title: Improvements in or relating to parametric resonant circuit devices
IPC: H03F7/02
Filed: 1961-06-08
Abstract: 970,997. Parametric amplifiers. WESTERN ELECTRIC CO. Inc. June 8, 1961 [June 27, 1960], No. 20732/61. Heading H3B. A parametric amplifier or resonator comprises a cavity resonator 12 resonant at signal and pumping frequencies and a rod 17 of superconductive material. The rod is magnetically biased in the region of its critical field strength so that its conducting state and its permeability are varied at the pumping frequency. Suitable alloys having high permeability at low temperature are described. The alloys comprise two or more of the elements cerium, gadolinium, osmium, ruthenium, thorium, yttrium. The magnetic bias in rod 17 accompanies a current from battery 18. A pumping source 28, connected to probe 31, injects into the cavity a pumping wave in the TEM mode. The magnetic fields due to the bias and the pumping wave are indicated by the continuous line and the dotted line in Fig. 1a. A circulator 23 is used to inject the signal from source 22 via probe 26 and to feed the output to load 27. In a modification, Fig. 2, the superconductive rod 63 is mounted on dielectric rods 44, 46 and is magnetically biased longitudinally by a magnet having polepieces 47, 48. The pumping frequency from source 49 is injected by probe 52 into the cavity 42 in the TE011 mode (see Fig. 2a). The signal is injected as before in the TEM mode. In a third embodiment, Fig. 3, the superconductive rod is the junction between two conical parts 63, 64 of superconductive material. The resonant cavity is the space bounded by the two conical parts 63, 64 and a wall 66. Both pump and signal waves are injected in the TEM modes as in Fig. 1. The device is biased by a current IDC between the two conical parts. The resonator is housed in a refrigerator 32, Figs. 1 and 3, or 59, Fig. 2.

Title: Improvements in and relating to point detectors for railways
IPC: B61L5/10
Filed: 1920-07-02
Abstract: 169,672. Simms, W. H., (General Railway Signal Co.). July 2, 1920. Signals and points, interlocking. - A pointdetector associated with electrically-operated switches has a number of sliding detector bars with notches in their edges, and a circuit-controller with rollers co-operating with the notches, is rocked to a position corresponding to the position of the switches. The circuit controller has a contact carrier C rocking on a pin 134 supported by arms 132 on a yoke Y which is pivoted at the end 135 and pressed downwards by a spring 137 arranged between the yoke and the top-plate 136. The contact-carrier has an operating-foot 127 at its lower end and an insulating block 128 with contacts 129 at the upper end arranged to contact with spring fingers 130. Two spindles 138 on the contact-carrier support two sets N, R of loose rollers. The detecting bars D pass transversely through the apparatus and the grooves in their upper edges pass under the rollers N, R. When the apparatus is applied to a single pair of switches, two bars D are connected to the switches by rods 146, 147 and are adjusted so that with the switches in the normal position, as shown in Fig. 4, the rollers N drop into notches in the bars and throw the contacts 129 to the left to complete the control circuits. Upon the unlocking movement of the switch apparatus occurring, the locking-plunger LP and the dog 56 engage the bevelled end of the foot 127 and force the contacts 129 to the middle position in which the circuits are broken. When the points are thrown to the reverse position and the plunger LP has made its locking movement, the contacts 129 are thrown to the right to complete the control circuits. The apparatus thus ensures that the points shall be locked in the operative position before circuits can be established by the contacts 129. Each bar D has a short notch and a long notch to allow for adjustment and to ensure the accurate position of the closed point, as the operative notch on the bar connected to the closed point is always the short notch. The device may be applied to a number of points and the bars may be inserted and operated from either side of the apparatus. Where four bars are used, they may be coupled in pairs. The rod 153, Fig. 11, is connected to the switch point and to the lug 152 on the bar D<1>. The lug 154 on the same bar carries a screw pin 155 which passes through a lug 156 on the bar D<2>. Adjustment of the bars D<1>, D<2> is obtained by rotating the nuts 157.

Abstract: 385,234. Rail-lubricating devices. MAINTENANCE EQUIPMENT CO., 80, East Jackson Boulevard, Chicago, U.S.A. July 25, 1932, No. 20981. Convention date, Aug. 31, 1931. [Class 12 (iii] A rail-lubricating device for application to railway curves comprises a main lubricant reservoir 15, Fig. 3, located outside the track and containing a spring-pressed plunger 22, an auxiliary reservoir 36 having a discharge port 38 and communicating with the reservoir 15 by an inlet port 37, and a sliding ported plate 40 which is depressed by the flange of a passing wheel 7 to open the port 37 and is thereafter released to cut off the main reservoir and allow some of the lubricant cut off in the reservoir 36 to discharge under its own pressure via the port 38 and a passage 43 on to the rail head 6. The chamber 36 is formed in a plate 32 which is pressed against a plate 9 by means of bolts 33, nuts 34 and springs 35. The plate 40 slides in a recess 39 in the plate 32 and is maintained in the normal raised position shown in Fig. 3 by springs 44, Fig. 2, housed in recesses formed jointly in the plates 9, 40, 32. The ports 41, 42 in the plate 40 are arranged so that the outlet port 38 is closed when the wheel depresses the plate 40. Thus if a wheel comes to rest over the plate 40, lubricant does not leave the reservoir 36 until the wheel has passed on. The reservoir 15 is rigidly connected to the rail and the plate 9 by a threaded pipe 13. A filling plug is provided adjacent the end 17 of the main reservoir. The spindle 23 serves as an indicating means for the contents of the reservoir 15 and is threaded so that the plunger may be drawn back during filling by the application of a suitable tool. The plate 32 has flanges 49, Fig. 2, which protect the springs 35 from flying gravel and a well 50, Fig. 3, which catches any overflow of lubricant from the passage 43. In a modification, the reservoir 15 is secured to the sleepers and the conduit 13 is made flexible. More than one passage 43 may be provided.
