Title: Electric circuit breaker having arc-extinguishing arrangements
IPC: H01H33/70
Filed: 1938-04-19
Abstract: 502,443. Fluid -- blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. April 19, 1938, No. 11753. Convention date, April 16, 1937. [Class 38 (v)] A circuit - breaker with a differential piston causing a flow of extinguishing fluid through an opening in the piston traversed by the movable contact, is provided with an additional device for extinguishing smallcurrent arcs and consisting of a cylinder and a piston which is movable in the cylinder and actuated by the breaker - operating mechanism. The differential piston 21 works in a cylinder 22 and is cup-shaped to receive the additional device 9, 12, and has slits 27 and channels 28 leading to the space 24 outside the piston. When the movable contact 2 is raised so that its tip has opened the slits 27, the piston is raised by the arc-pressure, thereby forcing a blast of extinguishing medium from the space 24, through the channels 28 and slits 27 on to the arc. When the contact clears opening 30, the blast is directed upwards into the space above the piston-bottom 25. On further movement of the contact 2, a shoulder 17 engages a shoulder on the upper end of the piston 12, which is raised to squeeze fluid from inside the cylinder 9, through openings 15 on to the contact tip, which is just above the opening 14 in wall 13, and also through the bore 16 in the contact 2. In moving downwards, the piston 12 creates a vacuum in cylinder 9 whereby the latter is refilled past the lightlyloaded valve or packing 11. The Specification as open to inspection under Sect. 91 describes also the arrangement according to which the additional piston and cylinder are used alone, the piston being raised and lowered by the engagement of a rim on the contact 2 with shoulders on the upper part of the piston. This subjectmatter does not appear in the Specification as accepted.

Title: Alkamine esters of pyrrole substituted acrylic acids
IPC: C07D207/34
Filed: 1944-06-23
Abstract: Alkamine esters of 1 : 2 : 4-trimethylpyrrole-5-carboxylic acid-3-acrylic acid of the general formula <FORM:0585834/IV/1> where X is a dialkylaminoalkyl radical, are prepared by heating the corresponding alkyl ester with the desired dialkylamino alcohol in the presence of an alkali metal alcoholate.  The starting materials for the present invention are preferably obtained by the reaction of pyrrole aldehydes with an alkyl acid malonate in the presence of a base such as piperidine.  In examples: (1) diethyl-1 : 2 : 4-trimethylpyrrole-5-carboxylate-3-b -acrylate is refluxed with b -diethylaminoethanol in the presence of sodium; (2) as in example (1) except that b -diethylaminopropanol is used as the alcohol.  The compounds of the invention are used in the form of their hydrochlorides as local an sthetics and in the form of the free bases as activators for rubber accelerators.  The parent alkyl esters are prepared by reacting the pyrrole aldehyde with an alkyl acid malonate in the presence of a base such as piperidine. The pyrrole aldehyde is prepared by the action of zinc cyanide and hydrogen chloride at low temperature on ethyl 1 : 2 : 4-trimethylpyrrole-5-carboxylate.

Title: Improvements in and relating to neutron detectors
IPC: G01T3/06
Filed: 1955-04-29
Abstract: 806,306. Neutron detectors. GENERAL ELECTRIC CO. April 29, 1955 [April 30, 1954], No. 12515/55. Class 40 (3). [Also in Group XL (a)] A neutron detector comprises two annular axially aligned chambers containing a scintillating phosphor between which is situated a target of samarium oxide which responds to neutron capture by emitting radiations detected by the scintillating phosphors. As shown, the phosphor 15, which is preferably toluene terphenyl, is contained in annular housings 13, 14 which are of aluminium. The housings are axially aligned and supported by mounting legs 16 while between the housings is a holder 18 containing a disc-shaped target 17 of samarium oxide. The ends of photo-multipliers 19 enter the phosphor housings and are sealed by rubber gaskets 22. The output of the two sets of multipliers associated with the two chambers of phosphor are separately amplified and fed to a coincidence circuit so that random pulses produced by neutrons scattered by the target affect one detector only while gamma rays produced by neutron capture in the target produce simultaneous light flashes in both phosphors and pass through the coincident circuit to operate a counting circuit.
