Title: Steam-cracker butene(s) cut upgraded to pure butene-1, gasoline - and opt. jet fuel via initial polymerisation-dismutation on acid catalyst
Inventor: JUGUIN BERNARD
IPC: C10L1/06
Filed: 1981-07-02
Abstract: High-purity butene-1 and high-octane gasoline are obtd. as follows from an olefinic C4 cut, low in butadiene, e.g. from a steam cracker. (a) The feedstock is polymerised-dismutated, giving largely a mixt. of jet-fuel cut, gasoline, butenes-2, and esp. butene-1. (b) The prod. is fractionated to a mixt. (i) of gasoline and jet-fuel cut, and a mixt. (ii) of butanes and butenes. (c) The C4 mixt. (ii) passes to finishing-polymerisation, where more than 90% of the isobutene is converted to gasoline. (d) The step (c) prod. is fractionated into a gasoline (iii) comprising mainly butenes dimers and trimers, and another C4 mixt. (iv). (e) The latter (iv) is selectively hydrogenated to reduce the butadiene concn. to 10 ppm of the butene-1. (f) The prod. is debutanised, removing most of its isobutane. (g) The debutanised fraction is fractionated into butene-1 (v) of minimum purity 99 wt.%, and a mixt. (vi) of largely butenes-2 and n-butane. (h) The gasoline (iii) and the mixt. (i) of gasoline and jet-fuel cut are mixed, for possible further treatment. Upgrading of the olefinic C4 cut is improved.

Title: Automatic trimming of film from laminated glass borders - using self-aligning, self-propelled cutting head
Inventor: CIRILLO FRANCESCO
IPC: B26F1/38
Filed: 1981-07-24
Abstract: Device for trimming excess borders from sheet matls. specifically film protruding from laminated glass panels, has cutting tools mounted on a head designed to automatically follow both the perimeter of the sheet while remaining aligned with the plane of the border of the sheet. The cutting tools may comprise one or pref. two blades, opt. hot. The cutter may be carried by a self-propelled dolly controlled by sensors associated with the cutting head so that the cutter proceeds around the perimeter of a static sheet. Alt. the cutting head may remain stationary with the border of the sheet being fed automatically between the jaws of the head. Mechanical angular movements of the head relative to the dolly is possible, to allow the heat to maintain an optimum cutting angle range around relatively short radius corners on the sheet. Used esp. for trimming surplus polyvinylbutyral film from the edges of laminated windscreens for vehicles, boats, etc., in preference to traditional manual methods which are time consuming and prone to damage knives and/or the edges of the glass.

Title: One person tent with removable side wall - has sliding clasp fasteners around wall to enable two similar tents to be joined together
Inventor: ANGLADE RAYMOND
IPC: E04H15/18
Filed: 1981-08-13
Abstract: The one person tent has a roof made from triangular panels (1-4), supported by a pole (13) and vertical walls (5-8). The tops of the triangles together form an angle of 180 degrees so that one wall is completely vertical. This wall can be removed so that two tents can be joined together. The edges of the walls have detachable sliding clasp fasteners with double cursors to join them to the tent or to join the two edges of the double tent. When two tents are joined the removable walls form a groundsheet that exactly covers the floor area of the tents.

Title: Knot release mechanism for baling machine binding mechanism - includes cam operated cord tensioning lever carrying forked release lever
Inventor: CLOSTERMEYER GERHARD
IPC: A01F15/14
Filed: 1981-08-25
Abstract: The cord binding mechanism for an agricultural baling machine includes a device for disengaging the knot from the knotting members in which two arms are swung by a rotating cam system. One arm controls a cord pulling member which is moved in a space between a guiding finger (16) mounted above a lever (12) controlled by the second arm (9), and the knotting device, which is above it. The cord is blocked below the knotting device before and during the disengaging operation. The lever is swung from a position in which it advances the cord to the guiding finger into a positin in which it blocks the cord between a plate (14) which carries the lever and one end (17) of a second forked lever tilted about the same pivot point (11) of the first lever. These levers have sufficient resilience to compensate for different cord sizes. (Correction to patentee in week 8214).

Patent FR-2519036-A1 (FR)
Inventor: BATTIGELLI JEAN A
IPC: D04H1/72
Filed: 1981-12-28
Abstract: The invention concerns the improvement of the fiber distribution in a web or mat, the attenuation of the fibers being effected by means of gas currents. The material delivered in the form of filaments is attenuated in a channel between two gas jets. At the outlet of the channel, the gas current carrying the fibers entrains the ambient air and passes through a guide apparatus containing two walls. The circulation of the air induced between the channel and the guide apparatus is modified by the interposition of baffles. The modification provides for improvement in the uniformity in the fiber web being made.

Title: Somatostatin analogue nona:peptide(s) contain alpha-hydrazino acid - inhibit growth hormone and glucagon secretion, without affecting insulin and gastric secretion, and have longer activity duration
Inventor: PERREAUT PIERRE
IPC: A61K38/00
Filed: 1982-03-05
Abstract: Somatostatin analogues of formula (I) and their salts are new. In (I), X1 and X2 are each -NH-A and A is an alpha-aminoacid residue, pref. Phe-NH- i.e. the X1, X2 group is -NH-NH-CH(CH2-phenyl)-CO-. (I) are compared with somatostatin in tests showing their effect on the secretion of insulin, glucagon, growth hormone (GH) and gastric juices. The concentration to inhibit 50% of hormone secretion was determined and converted to activity % (somatostatin = 100). (I) inhibit GH secretion strongly and may be used to treat acromegalia. The different inhibitory action against insulin and glucagon allows (I) to be used in insulin and non-insulin dependent sugar diabetes treatment. The fact that (I) does not inhibit gastric secretion and has better resistant to proteolytic enzymes (i.e. longer half-life) than somatostatin make them very useful. (I) are also easier to synthesise (9 amino acid chain as opposed to 14 of somatostatin. (I) have low toxicity and may be administered by subcutaneous; intramuscular or intravenous injection, generally in doses of 0.1-10 mg.

Title: Extrusion gun for mastic - has coupling which prevents continuation of mastic flow when handle is released
IPC: E04F21/30
Filed: 1982-04-28
Abstract: The extrusion gun for mastic comprises a handle (4) at the rear of a cartridge holder (1) and a plunger (7) which passes through holes in two spring-biassed plates (6,9). When squeezed, the handle tilts the first plate (6) which grips the plunger (7) forcing mastic out of the gun. When the handle is partially released, the first plate moves back along the plunger which is held stationary by the second plate allowing the action to be repeated. However, when the handle is fully released, the second plate is released from the plunger by a bar (12) extending from the handle, preventing wastage when the gun is not in use.
