Title: Antiinflammatory and antirheumatic agent prodn. - esp. N-tri:fluoro:methyl-phenyl-anthranilic acid hydroxy-ethoxy-ethyl ester
Inventor: BOLTZE KARL-HEINZ DIPL CHEM DR
IPC: C07C227/16
Filed: 1977-08-06
Abstract: In the prodn. of N-(m-trifluoromethylphenyl)-anthranilic acid 2-(2-hydroxyethoxy)ethyl ester (etofenamate) (I), an alkali salt of N-(m-trifluoromethylphenyl)anthranilic acid (II) is reacted with a halide of formula (III) and the resulting cpd. of formula (IV) is hydrogenolysed. In the formulae R is H or -OCH2CH2OCH2CH2Cl; m is 1 or 2; and X is H when m is 2 or H2 when m is 1. The esterification reaction proceeds in good yield without side reactions. The hydrogenolysis of (IV) is practically quantitative and gives a pure end-prod. which does not require expensive purificn.

Title: Component feed mechanism for nailing machine - has sorting slide spacing at correct intervals in trough before conveyor
Inventor: MARTIN FRIEDRICH
IPC: B65B15/04
Filed: 1977-09-09
Abstract: The system aligns and feeds components such as bearing parts and hinges to a machine nailing them to frames etc. The components are delivered, preferably in a particular alignment, from the machine producing them into a transport trough. After this a sorting slide spaces the nails out at the correct intervals and delivers them onto a second conveyor in belt or hose form. This enables the nails to be indexed forward into the working area. Conveyor and components can be brought into physical contact to allow pressure or ultrasonic vibration to be applied from outside.

Title: Solar heat collector - with air space communicating with compensating space contg. air bladder with open access
Inventor: PETZ FRANZ ING GRAD
IPC: F24J2/46
Filed: 1978-01-24
Abstract: A solar heat collector has the absorber elements arranged under a transparent cover plate in an air space, resting on an insulation layer such as plastic foam. The air space communicates with another enclosed air space at the rear of the insulation block in which an air bladder is located. This air bladder has with its inside free access to the atmosphere. Any excess pressure is thus instantly equalised without exposing the air space to any contaimination by dust which would impair the transparency of the cover plate.

Title: Safety catch for car seat back - has holes under hook for plastic deformation during accident to grip catch bolt tightly
Inventor: KLUETING BERND ING GRAD
IPC: B60N2/22
Filed: 1978-01-26
Abstract: The safety catch for the tipping seat back has the hook (18) provided with one or mor weight reducing holes (40) near the support face of the claw. This part of the claw suffers plastic deformation under large crash forces and prevents damage to the claw mounting. The plastic deformation ensures that the claw grips the safety catch bolt tightly and does not slip off. the impact force is dampened considerably so that a relatively light and effective safety catch can be used.

Title: Embankment or trench clearing cutter cylinder - has short bed working plates in offset helical lines at acute angles
Inventor: TRENKLE LOTHAR
IPC: E02F5/02
Filed: 1978-01-27
Abstract: For working on road embankments or trenches, clearing grass and weeds, the motor-driven cutter drumis mounted to swivel at the side of a vehicle, on a jib arm; it comprises two linked truncated-pyramidal drum sections with staggered blades on their sheathing surfaces. The cutter plates, set on the outer drum section (1a), for work on the trench bed, are short plates (2), jutting out vertically from the sheat surface. They are set at an acute angle, up to max. 30 deg., in the direction of rotation (D), in mutually offset helical lines, at an interval of about blade length. They may be detachably inserted in pockets on the drum section. The arrangement reduces resistance to the cutting tools.

Title: Thin, pore-free copper foil mfr. - by forming on metal carrier having chromium (oxide) release layer
Inventor: HUTKIN IRVING JOSEPH
IPC: C25D1/04
Filed: 1978-05-09
Abstract: A thin, pore-free Cu foil is made by (a) disposing a thin layer of Zn or Sn on the surface of a thin Al carrier; (b) disposing a thin Cr (oxide) release layer contg. numerous plating sites on the Zn or Sn, (c) depositing Cu on the release layer to form a pore-free Cu foil, (d) bodning the exposed Cu face to a substrate forming a laminate and (e) sepg. the release from the Cu foil. The substrate is pref. plastic; the metal carrier surface is roughened and/or a thin layer of Cu and Cu oxide nodules is deposited on the Cu to enhance the bondability of the Cu to the plastic substrate. Very thin, supported Cu foils are made which are readily released from the carrier, as the Cr(oxide) adheres only lightly to Cu yet contains sufficient pores for pore-free Cu to be deposited. The thin layers avoid Cu wastage and allow close element spacing.

Title: Assembly tool for sprung hose clip - has clip engaging scissor jaws pushed together by piston operated axial wedge
Inventor: WOESTE HERMANN
IPC: B25B25/00
Filed: 1978-09-15
Abstract: The clamp ring opener has a power cylinder (1) with a tapered extended end (2) on which two levers (4) are fitted on hinges (5). The lower ends of the levers are operated by a wedge (11) fitted to the end of a piston rod (10) so that when pressure medium is admitted to the power cylinder wedge moves forward and forces apart the lower end. The upper ends of levers are provided with recesses (12) into which the free ends of a clamping ring (8) can be engaged. When the lower ends of the levers are forced apart by the forward movement of the wedge the upper ends move closer, opening up the loop of the clamping ring.

Title: Telephone exchange circuit for multiple lines - has two auxiliary relays carrying out various switching steps using sensor operated by voltage generator
Inventor: MARCO FRANCO DE
IPC: H04Q3/00
Filed: 1978-10-13
Abstract: The circuit is in a telephone exchange operating by step-by-step selection and motor driven uniselectors. It is connected in relay contacts of connecting units, and to a selector which operates a testing or a companion relay. A first auxiliary relay (X) is in parallel with relay contacts (r, t) of the connecting unit of the bunch first wire (step JF). A current sensor (RC) is activated by a voltage generator (C), detects on the est wire (c1) a voltage insufficient for the test relay (P) operation, and operates a second auxiliary relay (V1). The first relay (X) operates when the first wire is engaged, and connects the voltage generator (C) with further bunch steps, while the second relay (V1) causes the companion relay (V) to operate, switches test relay (P) from the test wire (c1) to the probe (RC) output, and the probe input to the generator (c) other terminal.

Title: High-severity catalytic cracking - using mixt. of faujasite and mordenite as catalyst
Inventor: CHESTER ARTHUR WARREN
IPC: B01J29/18
Filed: 1979-01-11
Abstract: Cracking of hydrocarbon feeds (esp. gas oils) contg. aromatic and non-aromatic components is carried out at 900-1200 degrees F, a pressure of 0-100 psig, a contact time of 0.5-900 sec and a catalyst/oil ratio of 1-20, using a catalyst comprising a mixt. of faujasite and mordenite contg. 1.5 (pref. 0.5) wt.% alkali metal, with a faujasite: mordenite wt. ratio between 30:1 and 1:5. The catalyst activity and cracking conditions are controlled so that the degree of conversion exceeds that attributable to conversion of non-aromatics alone. The catalyst gives a lower coke yield than similar mordenite-free catalysts at high conversions, when cracking of aromatics would be expected to form large amts. of coke.

Title: Draw siphon - has a zone where fluid does not splash to give clean extraction from paper drying cylinder wall
Inventor: STEINER KARL DR
IPC: D21F5/10
Filed: 1979-01-27
Abstract: The construction of a draw siphon to remove fluid from the inner wall of a heated drying cylinder, in a papermaking machine, has a flow opening downstream of the leading blade edge of the draw blade. This gives a zone between the siphon and the fluid where spraying and dispersion of the fluid is reduced. The flow opening is a slit running approximately parallel to the leading edge of the blade. The inner side of the blade forms an angle with the fluid level at the draw blade of 25-35 degrees, pref. of 30 degrees. The end wall forms an angle with the fluid level which is less than the angle between the inner side of the blade and the fluid level. The upstream ends of the inlet have acute angled edges with inner guide surfaces and outer guide surfaces. The outer side of the blade runs downstream from the leading edge to a flow edge parallel to the fluid level to a tangent near the draw blade with an extending guide surface. The design ensures that the fluid is withdrawn easily and cleanly.
