Abstract: An expansion anchor for use in concrete structures includes an anchor sleeve in form of a wire block spring which is to be inserted into an expansion anchor hole. A conically tapering expander member is located at the leading end of this spring, and a bolt extends from the trailing end of the spring to the leading end and is engaged with the expander member which it draws into the spring thereby expanding the latter into engagement with the material surrounding the expansion anchor hole. An abutment is provided on the expander member which engages the leading end of the spring when the expander member has been drawn into the latter, and which shears off when the pull exerted by the bolt exceeds a certain limit, in order to thereby prevent the possibility that the surrounding material of the structure in which the expansion anchor is mounted might become damaged.

Abstract: A three-way urinary irrigation valve for use with a catheter is disclosed which is movable from a first position in which long term drainage takes place to a second position in which irrigating liquid can be introduced to a bladder, all while maintaining a closed system. The urinary irrigation valve includes a housing defining a first passage having an inlet leading to a bladder and an outlet leading to a drainage bag, and a second passage angularly disposed relative to the first passage and having an inlet at one end and an opposite closed end. A valve gate disposed in the second passage controls the flow of liquids between the inlet and outlet in the first passage, and between the inlet in the first passage and the second passage. An open-topped cap sealingly engages the housing adjacent the end of the second passage having the inlet.

Abstract: Bromine-containing phosphonic acid esters of the formula ##EQU1## in which R represents a halogen-containing linear or branched aliphatic or cycloaliphatic hydrocarbon radical having from 1 to 8 carbon atoms and R' and R" are hydrogen, halogen or alkyl groups having from 1 to 4 carbon atoms which may be closed to form a ring and/or substituted by halogen, at least one substituent being a bromine atom, are suitable as flame retardants for plastic materials, especially polystyrene and styrene copolymers.

Abstract: Inserted lineally in the output line of an oxygen supply apparatus between the regulator and the humidifier is a moisture trap. This captures moisture borne by a reverse flow of liquid from the humidifier produced by a vacuum occuring in the regulator when the apparatus is shut down and thereby protects minute oxygen flow orifices in the apparatus from impairment by calcification.

Abstract: An accessory attachment for use with a camera of the type having a frontal housing for an objective lens, a shutter mechanism, camera function-controlling devices such as photocells and shutter or control knobs or buttons, and having a socket for mounting a flashlamp. The attachment serves to mount accessories such as auxiliary portrait, wide-angle, or telephoto lenses, filter lenses for the camera's objective lens and photocell, auxiliary shutter or control knobs, and flash equipment, in operative relation to the corresponding elements of the camera. The attachment comprises a housing mounting the accessories, receivable against wall-forming means of the camera, and having hook elements engageable with an element of the wall means. A plug secured to the accessory attachment is slidably receivable in the flashlamp socket of the camera to cooperate with the hook elements in locating and securing the attachment.

Abstract: An expansion sleeve has a leading end and a trailing end, and an expander member is located at the leading end and can be drawn into the sleeve for expanding the same, by turning of a threaded member which extends through the sleeve and is engaged with the expander member. The threaded member has a portion extending outwardly beyond the trailing end of the sleeve. A nut is threaded onto this portion, and a mounting bracket, folded to form a passage, is placed onto this portion, so that the portion extends through the passage and the mounting bracket is located between the nut and the trailing end of the expansion sleeve. The mounting bracket is formed with cutouts or the like to which securing members for elements to be suspended can be fastened.

Abstract: A process for the production of high molecular weight .alpha., .beta.-unsaturated aldehydes by alkylation of the .gamma.-carbon atom of a lower molecular weight .alpha., .beta.-unsaturated aldehyde with a substituted allyl alcohol which has a chain branching in the 3-position carbon atom or a phenyl radical in the 3-position or of a corresponding allyl alcohol carboxylic ester at elevated temperature in the liquid phase.The products are valuable intermediates for the production of natural substances and odorants.

Abstract: An expansion anchor sleeve has a leading end and a trailing end, and an expander member is located at the leading end. A threaded member extends through the expansion sleeve and is connected with the expander member in order to draw the latter into the leading end of the sleeve to expand the sleeve. The threaded member has a portion projecting outwardly from the trailing end of the sleeve and a sheet-material bracket surrounds this portion and has a plane aligned with a longitudinal axis of the threaded member. The bracket is formed with apertures.

Abstract: An improved needle for use in knitting machines is disclosed herein. The improved needle can operate at higher speeds than prior art needles without undue needle breakage. The needles are of the type which have a hook and latch at one end, a shaft extending from the hook and a needle foot protruding outwardly from the shaft. The foot is adapted to ride in a needle foot guide channel which causes the needle to move in an axial direction. The improved needle has a shoe covering at least a portion of the needle foot. The shoe is fabricated from a material which has a shear modulus of at least one million pounds per square inch and a loss tangent greater than 0.01. The shoe may be fabricated from a metal or a metal-elastomer composite.
