Patent ES-456899-A1 (ES)
Title: Winches for the control of lifting equipment of the crane, overhead crane or similar type
IPC: B66D1/12
Filed: 1977-03-16
Abstract: The invention is an improved control mechanism for winches as used on cranes and similar devices having a single motor driving the shaft of a winch drum through a pair of eddy current clutches. Gear trains attached to the two clutches are operative to drive the drum's shaft in opposite directions. An electronic control generates an output signal indicative of a commanded speed and direction of drum rotation while a tachometer generates a signal indicative of the actual speed and direction of drum rotation. The electronic control system compares the commanded and actual speed as well as the direction of rotation and generates signals energizing the two clutches. The combined action of the two clutches stabilizes the rotational speed of the drum and its direction of rotation in accordance with the commanded input.

Title: Mechanism for the adjustment of the direction and of the amplitude of the movement of the transporting claw for material to be sewn on a sewing machine
IPC: D05B27/22
Filed: 1977-12-27
Abstract: A mechanism for a sewing machine for enabling the manual or automatic control of the direction and of the amplitude of movement of a transporting claw guide for material to be sewn.

Title: Process for 3{62 -aminoazetidin-2-ones
IPC: C07D205/08
Filed: 1978-03-07
Abstract: 1-[ alpha -(Carboxy)-4-hydroxybenzyl]-3 beta -aminoazetidin-2-one esters are prepared by converting 2-acyl-3,3-dialkyl-7-oxo- alpha -[4-(benzyloxy)phenyl]-4-thia-2,6-diazabicyclo[3.2.0]-heptane-6-acetic acid esters with mercuric acetate in an aqueous organic solvent mixture, e.g., in aqueous methanol, to 7-oxo-3-phenyl- alpha -[4-(benzyloxy)phenyl]-4-oxa-2,6-diazabicyclo[3.2.0]hept-2-ene-1-acetic acid esters and the latter are reacted with PCl5 and pyridine to provide the monocyclic 1-[ alpha -(carboxy)-4-benzyloxybenzyl]-3 beta -( alpha -chlorobenzylideneamino)-4-chloroazetidin-2-one esters. Reduction of the dichloro azetidin-2-one with an organo tin hydride and azobisisobutyronitrile affords the deschloro, 1-[ alpha -(carboxy)-4-benzyloxybenzyl]-3 beta -benzylideneaminoazetidin-2-one ester. The latter is hydrolyzed and the 4-benzyloxy group is cleaved via catalytic hydrogenolysis to yield an ester of 1-[ alpha -(carboxy)-4-hydroxybenzyl]-3 beta -aminoazetidin-2-one. The 3 beta -amino ester is useful for the preparation of the antibiotic FR 1923 (nocardicin).

Title: Flat-Iron with an Automatic Control System
IPC: D06F75/26
Filed: 1978-09-15
Abstract: In a flat-iron having two heating elements 3 and 4 individually controlled by zero-voltage switches 6 and 7, two temperature sensors 18 and 19 are associated one with each element, and the respective switch 6 or 7 is controlled dependent upon the sensed temperature. A temperature error signal is transferred by each of two gates (12 or 13) from a respective comparator (24 or 25) to the relevant switch (6 or 7), each comparator comparing the voltage drop across the relevant resistance (18 or 19) with a reference voltage. The gates 12 and 13 are enabled only when a signal is received from a common pulse generator 38. An acceleration-sensing switch 40 detects whether or not the iron is moving and inhibits switch-on if it is not.

Title: Method and device identifying the registering marks in order to position a reading aperture
IPC: B41F33/14
Filed: 1983-02-28
Abstract: A device for identifying registration marks includes two reading heads 30 and 31 connected by an amplifier 32 to an analyzing device 33 which processes the information read on the web 2 running over an engraved cylinder 38. An angular encoder 37 of the cylinder calculates the angular position of the engraved cylinder 38 while it rotates, and transmits it to the analyzing device 33, which memorises the received information from cycle to cycle of the cylinder 38. Said device 33 also sends out a signal 36 in order to control the idler roller 41 creating a positive or negative elongation of the web 2 between two points 47, 48 on it. The change in length, thus achieved, allows the identification of the registering marks, by comparing the different registering mark reading results before and after the change in length.

Title: Air atomising nozzle assembly.
IPC: B05B5/03
Filed: 1983-04-15
Abstract: An air atomising nozzle assembly for electrostatic spray guns is disclosed. The nozzle assembly is made of polyamideimide (<<Torlon>>) plastic parts and includes an air cap having a central bore which surrounds a fluid nozzle tip. The fluid nozzle tip has a nut formed on its forward end to facilitate threading of the rearward end of the nozzle tip into a threaded bore of the gun body. Formed on the front part of the nozzle, either as a part of the nut or a cylindrical surface adjacent the nut, is an accurately machined surface engageable in press fit relationship with a mating accurately machined bore of the air cap. These mating press fit surfaces centre the bore of the air cap relative to the nozzle tip so as to leave an annular, evenly dimensioned air flow passage surrounding the nozzle tip and defined between the nozzle tip and the air cap. The air cap is retained in a one piece resilient retaining ring by snapping the air cap into an annular lip of the retaining ring. The retaining ring is then threaded onto the gun body to secure the nozzle assembly onto the gun body.
