Title: Gas phase olefin polymerization process
IPC: C08F10/02
Filed: 1991-04-04
Granted: 1992-11-19
Abstract: The present invention relates to an alpha-olefin prepolymer catalytically active in an alpha-olefin (co-)polymerization comprising a transition metal, an organometallic compound and an antistatic agent. The prepolymer can be prepared by contacting the antistatic agent with a catalyst comprising the transition metal and the organometallic compound before or during an alpha-olefin prepolymerization. It can also be prepared by contacting the antistatic agent with an alpha-olefin prepolymer after a prepolymerization. It can also be prepared by a combination of the two methods. The prepolymer can be introduced into a gas phase (co-)polymerization medium for preparing polyolefin directly in a dry powder form, with a reduced amount of sheeting and agglomerates.

Title: Improvements relating to containers
Inventor: BRITTON CHARLES JONATHAN
IPC: B29C49/06
Filed: 1996-11-29
Granted: 1999-07-29
Abstract: A container is made in two stages from material such as thermoplastics that is deformable when heated. In the first stage a preform (1) is injection moulded, the mould parts easily releasing a tubular body (2) with a closed end. In the second stage the still heated preform (1) is blow moulded, possibly with some preliminary mechanical stretching, the blow pin being applied to the open end. The closed end of the body is stretched over a multi-part section (7, 8) of the mould which shapes the base of the container into an indent with an undercut formation, the cross section being generally omega-shaped. The multi-part mould section has a central tapered core (8) surrounded by an array of segments (7), the core (8) being fully inserted to spread the segments (7) for moulding, and being retracted to allow the segments (7) to close up and release the container after moulding. The divisions (12) between segments (7) produce ribs in the indent which provide added strength.

Title: Radio DF method with frame aerials - uses sum and difference circuits and produces square wave outputs proportional to sine and cosine components
IPC: G01S1/02
Filed: 1968-10-12
Abstract: The direction-finding method uses a pair of loop of frame aerial fixed at 90 degrees to each other (1, 2). Their outputs are alternately switched to the input of a mixer (8). The switching frequency is double that of the timing generator (5). The output of an auxiliary antenna (3) is switched at the generator frequency by a polarity reversing switch (7) to the second input of the mixer. The mixer output product is amplified and switched at twice the timer frequency to demodulator inputs (11, 12). The demodulators are driven at generator frequency. The demodulated signals are passed through filters and integrators (14, 15). The output of these circuits are square wave pulses which are proportional to the sine and consine of the angle of incidence of the received signal. The signals may be used to drive a cathode ray tube display (16).

Granted: 1999-12-27
Abstract: Data storage apparatus is known in which data is stored on a tape medium in at least two different longitudinally-spaced sections (Partitions 1 and 0) with data recordal in each section being effected in accordance with a predetermined format. This format will generally be of the type in which tape-usage information is recorded in a system log (82) located upstream of the main data area (37). It is also known to record tape usage information relating to each tape section (Partition 1,0) in the system log (82) of that section. The present apparatus provides not only for the recording of usage information from which section- specific information can be derived, but also for the recording of aggregated tape usage information. This latter information is stored in the system log (82) of the first tape section (Partition 1) so as to be readily accessible upon tape loading.
