Patent ES-354999-A1 (ES)
Title: Improvements in or relating to the detection of overheated axle boxes
IPC: G01N25/72
Filed: 1969-06-14
Abstract: In a hot axle-box detector of the type in which an infrared detector is imaged on to passing axle boxes and pulses produced gated in synchoronism with the passing axle-boxes, the arrangement includes at least one A.C. coupled amplifier stage operating with a substantially low signal output level at least during those periods when the pulses are not being passed. Amplifier saturation due to large infrared sources such as diesel exhausts is thereby prevented. The amplifier may be a temperature compensated amplifier similar to that disclosed in Specification 1, 175, 394 the only A.C. coupled stage being the first. Alternatively an amplifier similar to that disclosed in Specification 1, 162, 112 may be used with a switched feedback circuit which reduces the amplifier gain except when axle-boxes are passing the detector.

Title: Improvements in or relating to Patterning Mechanism for Circular Knitting Machines
IPC: D04B15/74
Filed: 1969-03-14
Abstract: The circular knitting machine described in Specification 1,029,373 is modified by replacing the stack of thin rotary discs influencing the pressers and thereby the jacks or needles by a perforated tape wrapped round a drum or extending round a number of drums and advanced at a rate corresponding with the speed of the cylinder so that the perforations in a surface of the tape influence the pressers to effect the selection. The drum is movable heightwise relative to the pressers but preferably the pressers are raised or lowered to bring the appropriate butt into engagement with a particular series of perforationis in the tape in order to achieve the desired selection.
Patent ES-371781-A1 (ES)
Title: Method and apparatus for the synchronized control of two hydraulic drives
IPC: F15B11/22
Filed: 1969-09-23
Abstract: Synchronization of two reversible hydraulic motors 2, 3 suitable for actuating ship's stabilizers and connected in series with a reversible pump 1 is maintained by a fluid-pressure pulse generated by a piston mechanically linked by a lever to the leading motor e.g., piston 8 linked by 14 to motor 3 and which pulse is transmitted from a cylinder space 16 along a line 25 to lift a valve 26 in a branch line 27 of the pump delivery line 10 thereby admitting sufficient pressurized fluid to the inlet line 11 of motor 2 to advance the same. Motor 2 is linked by 13 to a piston 7 which when displaced to the right by virtue of anticlockwise movement of motor 2 and link 13 draws fluid into a cylinder chamber 15 from chamber 16 through line 25 and a non-return valve 22 the two motors being in unison. In the event of motor 3 lagging behind motor 2 during their anticlockwise rotation synchronization is not effected until the pump 1 has been reversed and motor 2 reaches its mid position during it rotation in a clockwise direction when motor 3 leads and displaces a piston 9 to the right which directs a pressure pulse to lift a valve 28 to relieve excess oil from line 11 to a return 24.

Abstract: Foliar sprays for overcoming iron deficiency in iron chlorotic evergreen trees, e.g. citrus trees, Mexican and Guatemalan avocado trees and coffee bean trees, comprise water-soluble compounds which are non-toxic to the trees and are selected from the group consisting of polyols, ethers thereof and mixtures thereof, e.g. glycerol, ethylene glycol, propylene glycol, dipropylene glycol, triethyleneglycol, 1,3-butanediol, polypropylene glycol with an average molecular weight of around 425, pentaerythritol, sorbitol, mannitol, [alpha]-methyl-D-glucoside, [alpha]-methyl-D- mannoside, polyethylene glycols with up to 28 carbon atoms and mixtures thereof in conjunction with organic iron sources in the form of ferrous complexes of sulphomethylated conifer barks, ferrous and ferric salts of hydroxy acids or salts thereof, the hydroxy acids being, for example, gluconic acid, glucoheptonic acid, mixed gluconic and idonic acids, glucosaccharic acid, tartaric acid, citric acid, mannoheptonic acid, isosaccharinic acid. The non-toxic watersoluble compounds are present in amounts from 0À3% to 4% by weight of the spray solution and the organic iron sources are present in an amount sufficient to provide concentrations from 0À5 to 6À0 pounds of iron per 100 gallons of spray solution. The sprays may also contain lowbiuret urea in an amount ranging from 2À5 to 10 pounds per 100 gallons of spray solution. A spreader, e.g. sodium dioctyl sulphosuccinate, and a sticker may be included in the sprays. The sprays eliminate iron deficiency in the trees by penetrating the waxy surface of the leaves of the trees, thus allowing the iron in the spray to permeate throughout the iron-deficient area of the leaves.

Patent ES-415946-A1 (ES)
Title: Portable impact wrench
IPC: B25D16/00
Filed: 1973-06-15
Abstract: A portable impact wrench wherein a crank assembly reciprocates a cylinder which propels an impeller against the rear end of a tool holder in response to each of its forward strokes. The tool holder is rotatable stepwise in a single direction by a group of three sleeves the first of which is rotatable on but moves lengthwise with the cylinder and is normally held against rotation by a claw clutch one element of which is fixed to the housing. An intermediate sleeve has inclined teeth or threads meshing with complementary threads or teeth of the first sleeve so that the intermediate sleeve rotates back and forth in response to rearward and forward movements of the first sleeve. A third sleeve is rotatable in the housing and is connected with the intermediate sleeve by a one-way clutch. The tool holder is movable axially in but shares all angular movements of the third sleeve. Another element of the claw clutch is biased against the fixed element by a helical spring and has axially parallel teeth mating with complementary teeth of the first sleeve so that the latter can move axially but is normally held against rotation. The bias of the spring may be changed, terminated and/or assisted by a projection which can be manipulated by hand so that the user can apply his muscle power in order to increase the resistance of the other clutch element to disengagement from the fixed clutch element when the tool holder resists rotation with the third sleeve. When the claw clutch is disengaged and the cylinder continues to move forwardly and rearwardly, the intermediate sleeve rotates the first sleeve.

Title: Carbothermic production of aluminium
IPC: C22B5/14
Filed: 1980-04-09
Abstract: In a process for the treatment of fume-laden carbon monoxide evolved in carbothermic reduction of alumina the fume-laden gas is contacted with particulate carbon in a fluidized bed maintained at a temperature, preferably in the range 2010 DEG -2050 DEG C. and above that at which sticky aluminium oxycarbide forms.
