Title: Detection and measurement of no2 and o3
Inventor: TOPOL LEO E
IPC: G01N31/00
Filed: 1976-09-14
Granted: 1980-04-08
Abstract: ABSTRACT:  Small amounts of NO2 and O3 in air are determined by utilizing the reactions of these gases with solid alkali metal halides to produce halogen, and the reaction of NO2 with various salts such as PbI2 to produce NO;   halogens produced from the reaction may be measured by the use of an electrolytic cell, the output of which is dependent on the halogen concentration of the gas contacting one electrode thereof, while the NO concentration may be determined by the chemiluminescence technique.

Abstract: ABSTRACT OF THE DISCLOSURE           An electrical connector which utilizes a combination of tulip and butt contacts.  The female portion of the connector is formed by a longitudinally extending contact having a butt contact surface at one end thereof.  A plurality of spring loaded, tulip segments are arranged circumferentially around and radially spaced from the longitudinal axis of the contact.  The tulip segments and the butt contact surface together define a receiving socket for the male contact.  The male plug contact has a sloping annular surface which translates the inwardly directed radial force of the spring-loaded tulip segments into an axial force that provides a high pressure face or "butt" contact between the female contact butt surface and male plug contact.  In the preferred embodiment, the female contact butt surface has a conical configuration and the male plug contact has a truncated conical configuration.  This arrangment produces a ring contact electrical connection between the two portions of the connector.   1.

Title: Soldering iron with replaceable heating element and a  grounded handle and components thereof
Inventor: KNOWLES ALVIS R
IPC: B23K3/03

Granted: 1980-08-05
Abstract: ABSTRACT OF THE DISCLOSURE           A soldering iron can be constructed using a heating element structure or first part connected to a handle structure or second part through the use of connec-tors on these parts which are adapted to be secured together through the use of a rotary or twisting type motion.  The handle structure includes a spring biased sleeve which projects from it toward the heating element structure.          The heating element structure includes a metal flange which is resiliently engaged by the sleeve when the parts are connected together.  This flange in effect forms a part of a tubular, metal housing used to connect a body disposed in proximity to the heating element so as to conduct heat away from the heating element and the connector on the heating element structure.  The housing serves to protect the heating element structure against physical damage and is grounded through the flange and the sleeve to an appropriate grounding wire leading from the handle structure.

Title: Collecting mains for battery of horizontal coke ovens  and method of operating same
Inventor: WATSON LEWIS A
IPC: C10B27/00
Filed: 1977-03-18
Granted: 1980-12-09
Abstract: ABSTRACT OF THE DISCLOSURE           A battery of horizontal coke ovens which are connected to two gas collecting mains extending alongside the battery, and to a method of operating such a battery of horizontal coke ovens.          There are several advantages to preheating coal for coking before the same is charged into the ovens.  For example, there are various kinds of coal which do not yield sufficiently firm coke on degassing, but which do provide coke of higher quality if they are charged after preheating.  However, charging preheated coal into ovens causes problems because the resulting gas contains substantial quantities of dust during charging, as well as con-taining dust thereafter.  Dust remaining in the gas impedes the further processing thereof.  The present invention proposes to eliminate the nuisance of dust contained in the gases drawn off, resulting in trouble-free operation of the battery of coke ovens.          According to the present invention, one of the mains extending alongside the battery of horizontal coke ovens has means for sprinkling with an aqueous liquid which enables gas drawn from the ovens to be cooled to a temperature of approximately 100°C.          A second gas-collecting main is provided with indirect heating at which no gas constituents are separated from the gas which is drawn into the gas collecting main.  In the method according to this invention, a fan incorporated into the second gas collecting main maintains a gas velocity which is such as to prevent the settlement of dust contained in the gas.

Abstract: EMERGENCY PORTION FOR A BRAKE CONTROL VALVE                ABSTRACT OF THE DISCLOSURE       An inexpensive emergency valve device embodies a first movable abutment, subject on its respective opposite sides to the pressures in a brake pipe and a quick action chamber, that, upon a service rate of reduction of brake pipe pressure, unseats a poppet valve from one of two valve seats between which it is disposed so that, while unseated from both valve seats, fluid can flow at a service rate from the quick action chamber, one side of the first abutment and both sides of a second abutment, operatively connected to a combined emergency and brake pipe vent valve to atmosphere so  long as brake pipe pressure is reduced at a service rate thereby preventing an emergency brake application.  Upon an emergency rate of reduc-tion of brake pipe pressure, the quick action chamber pressure acting on the one side of the first abutment shifts the poppet valve into seating engagement with the other valve seat to cut of flow from the quick action chamber and one side of the second abutment to atmosphere whereupon the pressure of the trapped fluid under pressure on the one side of the second abutment deflects it to unseat the brake pipe vent valve to cause an emergency brake application.
