Abstract: A vibratory alarm assembly includes a cover that may be positioned on a mattress. A vibrator pocket is coupled to the cover. A controller pocket coupled to the cover. A vibrating member is positionable within the vibrator pocket. A controller is positionable within the controller pocket. The controller has a housing. The controller is operationally coupled to the vibrating member. A processor is coupled to the housing. An alarm is coupled to the housing. The alarm is operationally coupled to the processor. A microphone is coupled to the housing. The microphone is operationally coupled to the processor. A power supply is coupled to the housing.

Abstract: An extensible flat belt conveyor has a fixed section (1) and at least two extension sections (2) and (3). A chain (18) is carried over sprockets (21) and (22) on the portion (2) adjacent the fixed section (1), and its lower traverse is fastened to the fixed section while its upper traverse is fastened to the movable section (3). When a chain sprocket (22) is driven the movable section (3) travels twice as far and as fast as the section (2). A control module (25) is carried on the extending end of movable section (3), and is wired back to the fixed section (1) by an electrical cable (30) which extends through saddles (28) outstanding from the chain (18).

Abstract: Optical light filters, useful for eye protection from laser radiation, are provided. The filter can absorb harmful radiation from lasers of several (at least six (6)) types which have a range of different specific wavelengths, yet permit sufficient visibility. A novel mixture of compatible absorbers in a transparent plastic carrier, having the required stability to withstand processing conditions and having satisfactory stability for use under environmental conditions is disclosed.

Abstract: A method for heating a metallic strand 16 such as a wire or strip comprises passing the strand 16 along a metallic tube 4 which is filled with molten metal 13, the tube wall being heated by a furnace chamber 3 through which the tube 4 extends.

Abstract: The addition of a nickel salt of an omega-[4-hydroxyphenyl]-alkanoic acid having at least two alkyl groups on the phenyl ring to a reaction product of a polyalkyl-substituted 4-hydroxy benzoic acid and a secondary or tertiary organic phosphite results in lubricated polyolefins having enhanced resistance to yellowing.

Abstract: Compositions of nickel salts of 4-hydroxybenzoic acids and esters of aliphatic or aromatic carboxylic acids, which esters have boiling points of at least about 250.degree. C. are useful for stabilizing polyolefins against degradation by heat and ultraviolet radiation and for rendering polyolefins dyeable.

Abstract: A dyeable olefinic polymer composition comprising an olefinic polymer, and the reaction product of 50 to 90% by weight of the full nickel phenolate of o,o'-bis(p-1,1,3,3-tetramethylbutylphenol)sulfone and 50 to 10% by weight of a secondary or tertiary organic phosphite.

Abstract: Products of the reaction of about 30 to 90 parts by weight of a compound of formula (I) ##STR1## wherein R.sub.1 and R.sub.2 are each alkyl radicals having up to 8 carbon atoms at least one of which is branched on the alpha carbon, and R.sub.3 and R.sub.4 are each hydrogen or an alkyl radical having up to 18 carbon atoms, and about 70 to 10 parts by weight, respectively, of a secondary or tertiary phosphite are useful for stabilizing polyolefins against degradation by heat and ultraviolet radiation and for rendering polyolefins dyeable by chelatable dyes such as aromatic ortho hydroxy azo dyes.
