Abstract: Abstract In an integral storage collector solar heating system, water heated in a convention hot water heater (12) is first preheated in an integral storage collector (22).  The storage collector (22) includes a heat storing medium (46), preferably clean water, in a storage tank (40).  Water to be heated is forced by line pressure through heat exchange pipes (44) im-mersed in the heat storing water (46).  The heat of fusion of the storing water prevents freezing of the line water.  To preclude excessive pressure in the heat storage tank with high temperatures of the heat storing water, a heat pipe (52) is provided to act as a large heat leak at about the vaporiza-tion temperature of the water.  Also, a pressure relief valve (48) is provided.  The system avoids freezing and contamination of the water and does not require temperature control circuitry or a pump.

Abstract: 12                  48,280 A B S T R A C T ELECTRICAL REACTOR WITH FOIL WINDINGS   An iron core  shunt reactor for  power  factor improvement  of  transmission lines  is constructed of  a plurality of foil windings coaxially positioned along an iron core a discrete distance from each other.  A coolant circulates axially along the core  and radially outward between each of the  foil windings providing the shunt reactor with improved thermal characteristics.  The foil windings are all connected in parallel to form a neutral terminal and a line terminal.  The foil winding/s at the line terminal may have the foil width gradually decreasing as the winding progresses radially away from the winding axis so as to give a rounding off effect to the outer periphery of  the winding,  to obviate the corona.  The winding/s at the line end may additionally be encapsulated in  an  epoxy  resin.   This  construction  offers  reduced electromagnetic  forces  on  the  windings,  and  improved thermal as well as impulse distribution characteristics.

Abstract: Une bande d'étanchéité pour portes et fenêtres constituée de deux lames en matière synthétique formant un profil en V. Une troisième lame est fixée à la jointure des deux premières lames. Les lames sont recouvertes, sur leur face destinée à être collée au battant ou au bâti dormant, d'une couche de colle. La couche de colle est elle-même recouverte d'une couche amovible souple. Une gorge pratiquée à l'intérieur de la jointure des deux premières lames amincit la matière à cet endroit-là et donne la souplesse nécessaire. De même, une rainure permet de replier la troisième lame au cas où le battant n'est pas assez large pour coller la bande entière à plat. La configuration de cette bande d'étanchéité permet d'éviter le décollement dû aux efforts de traction répétée qui sont exercés lors de la fermeture et de l'ouverture de la porte ou de la fenêtre.

Abstract: 1?            Abstract A helical resonator filter comprising two or more helical coils is provided with a conductive coupling element between the helical coils for modifying the filter bandwidth.   A coupling element is a conductor and is positioned in the maximum of the electrical field at the open end of the helical coils or at the maximum of the magnetic field at the grounded end of the coils, or both thereby creating controlled change in capacitive (electrical) or inductive (magnetic) coupling, respectively.  A block of suitable dielectric with grooves for receiving the coupling element and the ribs on the inside of a conductive cover can be used to center the coupling element and the whole filter assembly structure when the cover is put in place and clamps the block securely to the base of the filter.  Additional coupling elements can be used in a similar manner as above when additional helical coils are used in a filter.

Abstract: ABSTRACT     In the preparation of ethylene glycol by reacting methanol, formal-dehyde and an organic peroxide, improved yields of ethylene glycol are achieved by the reaction of portions of the total amounts of formaldehyde and peroxide to be reacted with methanol.  Formaldehyde and peroxide are incrementally added to a liquid medium containing methanol in controlled amounts during the reaction to permit conversion of each portion of said formaldehyde and peroxide reactants prior to the next addition.  The portions are added such that the concentration of glycol in the reaction medium to which a later portion is added is greater than that to which an earlier portion is added. The reaction is continued until all the formaldehyde and peroxide has been incrementally added to the reaction medium and subjected to reaction conditions for a suitable period of time.
