Title: Olefin oligomerisation with supported catalyst
Inventor: AJAY MADHAV MADGAVKAR
IPC: C08F/
Filed: 1981-07-16
Granted: 1986-09-10
Abstract: Oligomerisation of 3-12C alpha-olefins is effected by contacting the olefin feed at -50 to +150 (pref. -10 to +50) deg.C with a catalyst comprising BF3 and H20 adsorbed on a particulate solid adsorbing. The H20 increases the activity of the catalyst and inhibits catalyst ageing without significantly affecting selectivity. Contacting an already deactivated catalyst with H20 also increases its acitivity (such a regeneration process is also claimed). The process is esp. useful for producing 1-decene trimer/tetramer mixts. for use as base oils for lubricants and other functional fluids. The adsorbent pref. comprises 50-100 % silica (esp. 100% silica) and has a particle size of 0.3-2.0 mm. The process is pref. carried out by passing an olefin feed contg. 5-130 ppm H20 through a bed of the catalyst at an LHSV of 0.1-50 while maintaining a BF3 partial pressure of 0-1000 (esp. 50-500) psig.

Title: Eicosa-penta-enoic acid derivs. prepn.
Inventor: QUADRO GIUSEPPE
IPC: A61K/
Filed: 1983-12-02
Granted: 1989-11-30
Abstract: The apparatus has an X-ray source (3) having an electron source (31) and a stationary anode (4) which describes a full or partial anode ring with a circuit for accelerating electrons emitted from the electron source, using a high positive constant voltage, towards the anode ring. The electrons form an electron beam (32) which collides with the anode ring at a focal spot (41) which, in turn, emits X-ray radiation in the form of a fan beam (42). With a full or partial X-ray detector ring (5) the detector ring and the anode ring are coaxially arranged and define a scan slice. The detector ring is such as to permit the spatial resolution around the ring of the X-rays detected. A number of electron sources are arranged on an electron source ring (33) in proximity to the anode ring. A circuit is provided to control the sources individually in order to emit electron beams in set time sequence. The focal spots produced by the electron beams on the anode ring are each electromagnetically swept over a portion of the anode ring.

Title: Frequency filter for radionavigation - compares resonant circuit outputs of different intervals
IPC: H03H/
Filed: 1974-09-27
Granted: 1978-03-20
Abstract: The filter is designed to pass the principal component of a composite frequency signal and consists of a parallel resonant circuit (LC) means of comparing a first sampled voltage (VB) at the terminals of the parallel resonant circuit and representative of the principal frequency component, with a second voltage (VA) proportional to the parallel resonant circuit current and representative of the frequency components outside the frequency acquisition interval. A further unit (AC) produces continuous frequency searching when the comparison indicates that the second voltage is greater than the first. The resonance of the resonant (LC) circuit is adjustable and the input is mixed with the output frequency of a variable frequency oscillator.
Patent IT-1030711-B (IT)
Title: Tyre structure tolerating use when deflated - having sidewalls lined with high elasticity rubber
Inventor: EDWARDS R H
IPC: B60C/
Filed: 1974-10-15
Granted: 1979-04-10
Abstract: Tyres, for wheels with internal lubrication systems, esp. two phase have a radial ply carcass with extra reinforcement for the beads and beneath the tread, where tread width is >=35% greater than the bead pitch between the wheel rims, the inflated tyre height/width ratio being 0.75. The thinnest point of the sidewal is >=5, pref. =10% of the overall tyre width, and has >=25% pref. 30-50% of the rubber content of the wall cross-section on the inner surface of the wall. The thickness of the lining layer of rubber should increase towards the shoulder sections of the tyres. Use of relatively high elasticity rubber for the sidewalls reduces the heat generation by hysteresis effect in the rolling folds of a sidewall when deflated, thus reducing internal friction and tyre wal damage. The excess tread and tyre width relative to the wheel rim pitch generates a simple fold pattern in the deflated tyre profile instead of the double inversion fold typical of a narrower tyre and generating more heat.

Title: Carousel-type core-making machine
Inventor: ZITSER VITALY ALEXANDROVICH
IPC: B22C/
Filed: 1981-11-30
Granted: 1987-06-18
Abstract: Core-making machine has a conveyance system supporting core boxes, each of which comprises an upper and a lower part. Each core box has a main gate and additional gates, mechanically interlinked by a pullrod and pivotable to close or open central and peripheral core print openings of the upper core box part. At the core box filling and pressing station, the additional gates are closed prior to pressing sand through the central openings, and the main gate is then closed. Before the core box separating station, all the gates are opened, e.g. at a core venting station, either by further drives or by a single drive which acts on the main gate via an adjustable one-way stop provided on the pullrod. The residence time of the core box at the pressing station can be reduced to a min. to avoid the risk of destruction of the solid skin on the mixt. at the ends of the peripheral core prints with a rotary brush and thus improve the quality of the cores produced.
