Title: Mortise lock
Inventor: ALEXANDER GORDON A
IPC: E05C1/16
Filed: 1979-06-29
Granted: 1980-03-11
Abstract: ABSTRACT           A mortise lock has a case, a spring projected latch bolt movable through the front of the case between projected and retracted positions, inner and outer rollback hubs journalled for independent coaxial rotation between the sidewalls of the case, and a retractor supported for movement relative to the case between first and second positions respectively corresponding to projected and re-tracted positions of the latch bolt in response to rotation of either of the hubs.  The retractor comprises a generally L-shaped metallic member positioned adjacent one of the sidewalls and has one leg disposed generally rearwardly of the hubs and another leg extending from the one leg beyond the hubs and toward the front of the case.  A non-metallic low friction retractor shoe, attached to the retractor adjacent its one leg, projects from the one leg toward the other of the sidewalls and is disposed rear-wardly of the hubs for engagement with the hubs.  A first guide pin mounted in fixed cantilever position on the case rearwardly of the hubs extends in the direction of retractor movement and is slidably received within a bore in the retractor shoe.  A second guide pin supported in fixed position on the case forward of the hubs, extends in a transverse direction relative to the direction of retractor movement and is slidably received within a slot formed in the forward end portion of the other leg.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to high ortho etherified resole resins. The resole resins are prepared by re-acting under acidic conditions phenol with formalde-hyde in the presence of a divalent electropositive metal. The resole resins are then etherified with an alcohol and dehydrated to less than 1 percent water. The novel high ortho etherified resole resins are useful in coating, bonding and adhesive compositions. Such resoles are readily curable with coreactive resins providing chemical and solvent resistance.

Abstract: ABSTRACT           Substantially pure 2,3,5,6-tetrachloro-pyridine is recovered from a mixture of chlorinated pyridines containing 2,3,5,6-tetrachloropyridine and other chlorinated pyridines in an improved process which comprises (a)  reacting by contacting a first mixture of chlorinated pyridines with chlorine in the presence of a strong Lewis acid catalyst to thereby obtain a second mixture consisting essentially of 2,3,5,6-tetrachloropyridine and pentachloropyridine, and (b)  recovering the 2,3,5,6-tetrachloropyridine from the second mixture.  The reaction is normally conducted at a temperature of from 150°C to 300°C by pressurizing chlorine into a molten mixture of the chlorinated pyridines and maintaining such conditions until substantially all of the isomers have been converted to the symmetrical tetrachloropyridine or pentachloropyridine.

Abstract: ABSTRACT OF THE DISCLOSURE     An electronic control system to automatically determine the validity of an apparent overheating signal from an overheat monitor of a gas-cooled dynamoelectric machine and reduce machine load or indicate a monitor malfunction.  Upon receipt of an apparent overheat signal by the control system, filtration of the monitored cooling gas is automatically initiated to remove pyrolysates released into the gas by overheated elements within the machine.  A normal monitor response is thereby effected, provided the overheat signal is valid.  If filtration of the monitored cooling gas fails to elioit a normal response within a preselected time period a monitor malfunction is indicated.  The control system initiates a scheduled reduction.  The control system initiated a validation of overheating or as verification is initiated, and if a valid indication of overloading persists, trips the excitation and remaining load from the machine. Redundant current paths, high-speed solid-state comparators, and timing elements are included in the control system for verifying the monitor signal.

Abstract: ABSTRACT OF THE DISCLOSURE     A high frequency filter for frequencies from the VHF band upwards has a closed conductive housing, input and output means such as antennas provided at opposite ends of the housing, a plurality of resonators arranged between the input and output means, each of the resonators having an elongated inner conductor with a circular cross section, and an elongated rectangular dielectric body surrounding the inner conductor, one end of each resonator being fixed to a common wall of the housing and the other end of each resonator being free standing.  The length of each inner conductor and dielectric body is substantially 1/4 wave-length, and the distance between two resonators is deter-mined according to the coupling coefficient required for the desired characteristics of the filter.  Due to the rectangular dielectric body, each resonator can be stably mounted on the housing, and thus stable filter characteris-tics are obtained.  Hence use in high vibration applications such as mobile communication is possible.  The rectangular dielectric body also provides larger coupling coefficients between resonators, and thus a wideband filter can be obtained.

Abstract: ABSTRACT  In the case of pin-setting installations using pins attached to cables,  the  cables stretch after a certain length of operating time.   In order to compensate for this, the cable-storage drums (6) are rotated, from time to time, to a small extent, in the winding-in direction, by a drive-mechanism.  This is achieved by means of a double-gear  coupling (36,40; 60,66). A belt-drive (22,23,24), communicating with the chain-drive, drives a gearwheel (44).  The latter engages with a coupling gearwheel (36) only when an electro-magnet (48) moves a cam  (40) attached to the coupling gearwheel, shifts the toothless sector (A) thereof, and brings the teeth into engagement. Shaft 38, rigidly connected to the coupling gearwheel,drives the cable-storage drum by means of a toothed segment, causing it to execute part of a revolution in the cable winding-in direction .
