Abstract: A bollard assembly is formed from a bollard that resides in a tubular socket. The socket has an internal core that is separated from the tube walls by annular recess. The lower end of the bollard is received within the recess. Lifting elements inside the bollard engage the upper surface of the core, and are internally biased in favor of extension. A locking system prevents extension of the lifting elements. When the locking system is unlocked, the pressure of the lifting elements against the core causes the bollard to rise out of and slightly above the socket, without external assistance. Once raised, the bollard may easily be removed from the site of the socket.

Abstract: Silicone rubber compositions are disclosed including a silicone polymer and a silicon-treated carbon black. The silicon-treated carbon blacks include a silicon-containing compound that is distributed through at least a portion of the carbon black aggregate. The silicon-treated carbon black is incorporated within a silicone rubber composition as an alternative reinforcing and extending filler, imparting higher hardness to elastomers formed from the composition, when compared to silicone rubber compositions incorporating an untreated carbon black.

Abstract: A method for the synthesis of the 2-propanone (I) is described starting from alkoxide (II) through the lactone (IV). ##STR1## Excellent control of the location of the substitution on the phenyl ring is achieved and the reaction proceeds in high yield.

Abstract: A digital pulsewidth modulator switch regulator is used in a power supply for a multisection vacuum fluorescent display system. Pulsewidth modulations are based on grid and anode load characteristics of each section of the display, stored prior to system operations in a designated location of memory of a microcomputer used for controlling switching regulations. Display voltage updates are made utilizing the stored data as well as new load data derived from the power supply output voltage feedback signals indicative of changes in the display voltage.

Abstract: Novel compounds, which are aryl-pyrrolyl-imine derivatives of the Formula I ##STR1## and acid addition salts thereof are disclosed; which compounds may be prepared by the acid catalyzed condensation of an imidoyl chloride with a lower alkyl pyrrole-2-acetate; and which compounds are useful as intermediates to form by hydrolysis, the known useful ketone analogs which have anti-inflammatory and analgesic activity; and certain of which compounds have antisecretory, anti-irritable bowel, antidiarrheal and general behavior effect on the CNS properties.

Abstract: An improved process for preparing fenoctimine, which is 4-(diphenylmethyl)-1-[(octylimino)methyl]piperidine by: (1) reacting dimethylformamide with dimethyl sulfate to form a complex; (2) reacting the resultant dimethylformamide/dimethyl sulfate complex with n-octylamine and optionally with dimethylamine; (3) thereafter treating the reaction with aqueous base to form N,N-dimethyl-N'-octyl-formamidine; and (4) reacting said formamidine, without need for further purification, with 4-(diphenylmethyl) piperidine to obtain 4-(diphenylmethyl)-1-[(octylimino)-methyl]piperidine.

Abstract: There is provided a novel method of synthesizing certain tetracyclic quinones. In particular, there is provided a novel route to the synthesis of (+)-7-deoxydaunomycinone and analogs thereof, which includes the provision of novel tri- and tetracyclic quinone intermediates. The -7-deoxydaunomycinone derived from naturally occurring daunomycin is a known compound, which is itself an intermediate in the preparation of the clinically accepted anti-tumor antibiotics daunomycine and its derivative adriamycin.
