IPC: H02P7/00
Filed: 1931-03-10
Abstract: 375,344. Master control of D. C. motors. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Cook, W. G.; 499, Marion Avenue, Forest Hills, Wilkinsburg, Pennsylvania, U.S.A.) March 10, 1931, No. 7374. Convention date, March 17, 1930. [Class 38 (iii).] Reversing.-A motor 6, as shown, is reversed by "plugging," and during "plugging" a high resistance 56 is maintained in circuit for a period determined by a time-limit relay 8 or 9 sensitive to the back E.M.F. of the motor. In the first position of a master controller 10, one of the directional contactors 3 or 4 and line contactor 5 are closed, the coil of the latter being energized over contacts 26 on the contactor 3 and contacts 106 on the relay 8. Relay 9 opens as its magnetizing coil 23 is energized and accelerating relays 14, 15 open as their magnetizing coils are shunted across resistance sections 55, 56. In the second position of the controller 10 contactor 11 closes immediately, and contactors 12, 13 close sequentially as the relays 15, 14 close with delays after the de-energization of their magnetizing coils. If the controller 10 is thrown from "full forward" to " full reverse " position, contactors 11, 12, 13 open as the controller passes through the "off" position, but contactor 11 does not reclose immediately since its original energizing circuit is opened at contacts 26, and an alternative circuit prepared at contacts 34 on the contactor is not completed until relay 9 closes, which does not occur until the motor comes to rest. In a modified arrangement the energizing circuits of the contactors 12, 13 are taken over stepped contacts on the drum 10 as well as over contacts of the accelerating relays, in order to allow additional stages of manual and automatic acceleration and deceleration. The Specification as open to inspection under Sect. 91 (3) (a) describes other arrangements. In one of these arrangements a polarized relay in the energizing circuit of the contactor 11 is used in conjunction with timed relays having their coils connected across resistance sections. In another arrangement the polarized relay is replaced by an additional timed relay. In a third arrangement the additional timed relay is duplicated, one relay being used for each direction of running. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,177,963. Netting device. UNION CARBIDE CORP. 16 Feb., 1967 [17 Feb., 1966]. No. 7456/67. Headings D1J and D1R. A netting machine comprises a pair of spaced apart, advancing endless chains 36, 37 carrying thereon a plurality of strand loop-receiving pins 57 and 58 and a looping member 89. (The latter is shown in side elevation in Fig. 4.). The looping member includes a cradle 82 pivotally mounted on an axis 84 which must be below the chains 36, 37, and a longitudinally extending carriage 77 which is slidably mounted on the upper ends 87, 88 of the cradle. The carriage 77 carries strand feed guides 74 pivotally mounted at 81. In use the looping member moves the strand guides 74 laterally across the path of the advancing pins and then advances them to the speed of the pins when they have passed the middle of .their lateral motion. The lower ends (57) of the strand guides are then pivoted outwardly through the spaces between the pins and then inwardly around the other side of the advancing pins. The extreme positions of the guides are shown in dotted lines. The looping member and the guides are then retracted relative to the pins and moved in the opposite lateral direction. The curved path of the extremities of the guides 74 may be above the level of the tips of the pins near the middle of the lateral motion; but desirably the curved path around the pins is below the level of the tips, see Figs. 5, 6 and 7 not shown. The strands can be fed to the guides under a predetermined air pressure applied through tubes 152. The air can be sucked or blown through the tubes 152 in order to counteract tension in the strands. The looping member can be advanced and retracted by crank arm 123 which is adjustably located in crank wheel 119. The strand guides can be pivoted by Bowden cables operated by a cam follower 137 running in track 138. The strands can be fed to the netting machine from packages via flexible conduits through which air is pumped or sucked, see Fig. 3 not shown.

Filed: 1968-02-16
Abstract: 1,212,529. Artificial respiration. F. M. BIRD and H. L. POHNDORF. 16 Feb., 1968 [28 Feb., 1967], No. 7630/68. Heading AST. A mechanical respiratory ventilator comprises an adapter 124 to supply gas to a patient and connected to a bellows 28, means for delivering gas to the bellows, means 91 for nebulizing the gas with a liquid, and means for causing the bellows to contract so as to force gas into the patient. The ventilator may also include means 37 for adjusting the size to which the bellows can be expanded so that a controlled tidal volume of gas is supplied to the patient. As shown, the ventilator comprises a control unit 51 which, while the patient breathes out through the adapter 124 and an exhalation valve 132, supplies oxygen (at a rate determined by an adjustment 90) through a line 88 and a nebulizer 91 into the expanding bellows 28. Air drawn in through a valve 107 may be added to the oxygen, and the nebulizer, which has a member 97 on which entrained liquid is broken into particles of 0.5 microns, may add water and optionally also a medicament to the breathing gas.  A member 37, 43, which is adjustable in its position, limits the expansion of the bellows so that the volume of gas supplied to the patient may be pre-determined. The exhalation phase is concluded when gas pressure (under the control of a timer knob 62) moves a diaphragm 64 and member 66 so that the gas may reach a junction 71 and act on a diaphragm 69 to close a valve 86 in the gas supply line 88. Inspiration is then caused by gas passing from the junction 71 through a line 138 and a venturi assembly 141 (where it is mixed with air) into the transparent calibrated canister 23 surrounding the bellows so that the bellows are forced to contract and expel gas to the patient. During inspiration, gas pressure through a line 138, 136 holds the exhalation valve 132 closed. Inspiration is concluded (under the control of a timer knob 73) when gas pressure on a diaphragm 76 opens a valve 82 to atmosphere so that the pressure on the diaphragm 64 is relieved and the valve member 66 closes allowing the valve 86 to reopen. A manometer 31 is provided.

Frequency changing and amplification of angle modulated waves of frequency F and modulation #F is effected by amplifying dividing and shifting the waves to produce a signal of frequency F/n + f/n with a modulation #F/n and amplifying and multiplying this signal frequency by n to produce an output F + f modulated by #F. Fig. 5 (not shown) illustrates a radio repeater in which the signal is amplified, divided, shifted by f/n in that order, further amplified and then multiplied. In Fig. 6 (not shown), the shift of frequency (by an amount f) is effected before division while in Fig. 7 (not shown), the incoming signal is divided before subsequent amplification and shift. Amplification and division may be effected by a locked oscillator and multiplication by a varactor diode circuit. The looked oscillator may have a common input circuit using a circulator of appropriate filters (Figs. 2 and 5, not shown).
