Title: Improvements in radio relay apparatus
IPC: H04B7/155
Filed: 1948-02-27
Abstract: 652,111. Radio signalling. RADIO CORPORATION OF AMERICA. Feb. 27, 1948, No. 6130. Convention date, Sept. 12, 1946. [Class 40 (v)] A radio relay system comprises means for transmitting test tones from a terminal station or test point to unattended relay stations and means at each of the latter for automatically returning a particular test tone, or signal derived from it, with or without further test information modulated on it if the relaying station is in proper operating condition. Diversity receivers 58, 60 for each way of reception at the relaying stations, with vertically arranged antennas 50, 52, both derive a 1 Mc/s. frequency-modulated sub-carrier and pass it for retransmission by frequency modulation (along with a service channel output on line 72) to a relaying transmitter 66, and in parallel with the service channel through a filter 76, a test tone, e.g. 400 c/s. individual to the station. If both the receivers are operative a gate bias is also derived, from a common rectified sub-carrier output on line 106, opening a gate 100 so that the test tone is permitted to pass to a modulator 102 which modulates the test tone with a low-frequency of 120 or 60 cycles depending on whether the relaying transmitter 66 associated with the receivers 58, 60 is " on " or " off frequency. This modulated test tone, together with a service channel modulation on the line 94 and a tone frequency, if any, indicative of abnormal conditions at the station such as transfer to an emergency power supply, is returned to the test point, West in this case, by frequency modulation on the westward carrier wave. A test tone level meter at the terminal station or test point in the service channel output indicates whether each of the two diversity reception receivers 58, 60 at the test relay station is in efficient order, but the modulator 102 is blocked if either does not receive and amplify radio frequencies since the line 106 blocking voltage is derived from the common output of two valves in parallel with grids fed through rectifiers from the receiver H.F. outputs. The 60 or 120 cycle tone is developed from the A.F.C. system of transmitter 66. A tone level comparison meter at the terminal station switches from the outputs of 60 and 120 cycle filters determines the correctness of frequency of the relaying transmitter.

Title: Improvements in and relating to multi-drum winders, hoists and the like
IPC: H02P3/06
Filed: 1939-02-28
Abstract: 527,016. Winding hoists and the like. GENERAL ELECTRIC CO., Ltd., and FOSTER, H. H. Feb. 28, 1939, No. 6593. [Class 78 (v)] A multi-drum winder, hoist, &c. is provided with a plurality of brakes, the application of one or more of which is adapted to be delayed. The Figure shows three solenoids 1 which hold off the brake on the second drum, except in an emergency, and the circuit of which includes a contactor 2 arranged to be opened by the opening 'of a safety control means 3. Each solenoid 1 is energized by a phase of a three-phase supply 4. The second brake is held off by one or more solenoids 5 energized by a constant voltage direct current generator 6 driven by the winder shaft 7. In the circuit of the solenoid 5 is a time-delay contactor 8, which allows the second brake to come on a few seconds after the first brake, and is operated by the energization of the control 3. The contacts of the contactor 8 are shunted by a switch 9 having double contacts and operated by a deceleration governor 10, also connected to the winder shaft 7. The governor 10 causes closure of one or the other pair of these contacts of switch 9, according to the direction of rotation of the shaft 7, if the deceleration produced by the brakes is greater than a predetermined value, thus shorting the time-delay contacts 8. In an emergency the safety circuit thus operates contactors 2 and applies the first brake, and later on the second brake comes on. If, however, the deceleration is sufficiently great, the contacts 9 are operated and nullify the effect of opening the time-delay contacts 8. The second brake then comes into action just before the winder comes to rest. When two drums are employed clutched separately to the shaft 7 a contactor 11 may be provided in the circuit of solenoid 5 and be arranged to open when the clutch of the second drum is disengaged, thus being ready for immediate application when the clutch is re-engaged. Manually operated brakes are also provided, means being fitted to prevent application of the delayed action brake independently of the governor 10. Specifications 426,394 and 483,580 are referred to.

IPC: F41J5/20
Filed: 1916-05-08
Abstract: 103,587. Vangen, A. May 8, 1916. Targets.-Relates to targets of the kind which are subdivided into annular sections each of which, when struck, backs as a whole and also tilts, i.e. makes a more pronounced backward movement at the part of the ring hit. A separate value-indicator is provided for every section, and indicators for lateral positions are operated by corresponding parts of all the rings. As shown in Fig. 1, each annular section 1, 2, 3, or 4 is carried by a loose collar 10, 11, 12, or 13 on the central sleeve 7, through which runs the stem 8 of the bull's-eye 5, and from each collar extends a rod, two 14, 16 of which are shown, to knock , a separate pivoted counterweighted indicator 20. The section struck and all those behind it are forced back momentarily against a common esetting-spring 23, which normally presses them against the end of the sleeve 7. Behind each quadrant is a sliding rod 40 bearing a cross-head 35. whence a pin 60, 61, or 62 extends to each annulus. The rod nearest the point struck is thrust back against its spring 65 and, being furnished with a lug 45, throws out an indicator 50. As shown in Fig. 4, the annuli have no collars, but are resisted and reset by separate springs 76, and each annulus operates its own value-indicator through one of a number of rods 70, which carry collars 77 acting on the cross-heads 35 of the position-indicating mechanism. As shown in Figs. 6 and 7, the annuli are in one plane and are attached to the rods 70 by ball joints, so that they are reset by the value-indicators and not by springs. As shown in Figs. 7 and 8, the lateral indicators 88 are adapted to rotate so as to be visible longer than indicators which return to rest after swinging out. The slide 80 represents the sliding rod 40, with cross-head, of the other figures, and a finger 84 thereon strikes a lug on the indicator. To prevent the finger from checking the rotation of the indicator, it lies loose on a stud 85 and is set only by a light spring 86.
