Abstract: This invention relates to a catalyst composition prepared by reacting in a hydrocarbon solvent a molybdenum or tungsten halide with siloxyalane selected from [(CH.sub.3 CH.sub.2).sub.2 AlO].sub.2 SiR.sub.2 and (R'.sub.3 SiO).sub.2 AlCH.sub.2 CH.sub.3 wherein R and R' are aryl or C.sub.1 -C.sub.5 alkyl. Preferably the halide is tungsten hexachloride, R is phenyl and R' is ethyl. The instant compositions are particularly useful as olefin disproportionation catalysts.

Abstract: Dejitterizer apparatus is disclosed which uses a counter to track the number of bits stored in a 64-bit FIFO buffer. The counter is incremented on a falling edge of pulses of a timing pulse signal, nominally 6.176 Mhz, that coincides with a pulse of a jittered, nominally 1.554 Mhz, clock pulse signal derived from a jittered T1 signal applied to the input of the apparatus. The counter is decremented on the rising edge of pulses of a local clock pulse signal which is derived from the timing pulse signal. The bits are stored in the buffer in response to pulses of the jittered clock pulse signal. Output from the buffer in response to timing pulses derived from the local clock pulse signal is enabled when the counter indicates that the buffer is one-half full. The frequency of the local clock pulse signal is a function of the average frequency of the jittered clock pulse signal over more than sixteen jittered clock periods.

Abstract: A process for the preparation of metal oxide substrates having tantalum (V) chloride/fluoride/oxide bound to the surface thereof.

Abstract: A lubricant composition having an improved viscosity index and flash point is prepared by reacting diisopropylbenzenes and hexylbenzenes with alpha olefins using a tantalum (V) halide/oxide-gel oxide catalyst.

Abstract: A protective cover for fragile boat bumpers includes two sheets of relatively thin rubber having a sheet of criss-crossing fibers therebetween, the two rubber sheets being fused to each other. The cover is initially formed from a blank of sheet stock comprised of two flat panels and a flange or wing extending from one of said flat panels so that when said flange or wing is overlapped with a marginal portion of the other of such panels and bonded thereto, a relatively flat tubular body is formed with a passage extending therethrough. The body has a pair of flaps hingedly connected to each end thereof so that the protective cover can be pulled downwardly over a boat bumper so as to protect the foamed sleeve of which the bumper is comprised from impact forces that would break and otherwise damage the relatively fragile foamed plastic, usually polystyrene.

Abstract: This invention relates to a process for converting propylene/butylene oligomers to dialkyl adipates where said adipates have higher flash points than conventionally prepared adipates.
