Abstract: An apparatus for producing liquid water from moisture in the air by adsorbing the moisture on an adsorbent and then desorbing water from the adsorbent by heating it and.condensing steam into liquid water. The water producing apparatus comprises a recycling passage for recycling steam through an adsorbent column in the desorbing step, a heater for heating the steam in the recycling passage; and a condenser branched from the recycling passage. In the desorbing step, steam in the recycling passage is heated bythe heater to heat the adsorbent and to desorb water from the adsorbent and excess of steam corresponding to the desorbed steam is passed from the recycling passagetothe branched condenser and is condensed to obtain liquid water in high efficiency.

Abstract: A gas pedal movement dampening arrangement has a spring assembly disposed on a base plate located directly beneath the gas pedal for a motor vehicle. In one embodiment, the damping unit comprises a spherical hollow elastic body having an air outlet nozzle which affords a linearly progressively increasing resistance force to further downward movement of a gas pedal until beyond a certain point whereupon the resistance force decreases. This enables free movement to full-throttle positions of the gas pedal if such is desired. In another embodiment, the damper unit comprises a spring assembly with a U-shaped spring biasing against downward movement of the gas pedal. Switch means operating upon movement of the gas pedal are also provided for controlling an indicator system informing the vehicle operator of his driving condition as a function of gas pedal movement. In a further embodiment, the damper unit and switch means are contained within a hemispherically shaped hollow body which is engageable by the gas pedal.

Abstract: Butyrolactone is produced by oxidizing an aldehyde-ether of the general formula:
     wherein R, and R 2  each, independently of the other, represent a C, to C 4  alkyl radical, and R 3  and R 4  each, independently of the other, represent a hydrogen atom or a C, to C 3  alkyl radical, or wherein R, represents a C, to C 4  alkyl radical, R 2  and R 3  together with the carbon atoms to which they are attached form a 5-membered or 6-membered cycloaliphatic ring, and R 4  represents a hydrogen atom or a C, to C 3  alkyl radical, to form an acid ether of the general formula:
     followed by deetherification, dehydration and cyclization. Oxidation can be carried out with e.g. gaseous oxygen. Deetherification can be accomplished by contact with an acid catalyst, whilst cyclization may occur spontaneously. A cyclic process is described in which allyl alcohol is converted by reaction with a suitable olefin, e.g. iso-butylene, to an allyl ether of a tertiary alcohol, e.g. allyl t-butyl ether, which is then hydroformylated to form the compound of formula (I), whilst the olefin, e.g. iso-butylene, released on deetherification of the acid ether of formula (II), is recycled to the allyl ether formation step.

Abstract: An apparatus (11) for applying toner particles (12) to a photoconductive surface (28) having multiple magnetic brushes (16,22) each of which consists essentially of a magnetic inner shaft (15,20) and a nonmagnetizable outer sleeve (19,24) with both the sleeve and the inner shaft of each brush being capable of independent rotation. The apparatus uses an adjustably mounted doctor blade (31) to apply toner particles to one of the brushes. The rotation of the inner shafts (15,20) and sleeves (19,24) of the brushes, the spacings between the brushes (16,22), as well as the magnetic attraction between the brushes affords the transfer of toner (12) from this first , brush (16) to the other brushes (22). Following the transfer of toner, each brush (16,22) is able to apply toner (12) to the photoconductive surface (28).

Abstract: Der Oszillator mit einem Schwingquarz mit einer Frequenz von beispielsweise 4,19 MHz weist eine Schaltung auf, die einen Niederfrequenz-Quarzresonator (NF) mit einer Frequenz von 32 kHz enthält und einen Schwebungsfrequenz-Generator (SFG) zum Erzeugen eines Korrektursignals, das auf einen programmierbaren Frequenzteiler (PRFT) geht und einen elektronischen Schalter (ES) zum periodischen Schalten des Hochfrequenz-Quarzresonators (HF). Durch das periodische kurze Einschalten des Hochfrequenz-Quarzschwingers, dessen Frequenzgang mit demjenigen des Niederfrequenz-Quarzes verglichen wird, wird erreicht, dass man einerseits die Vorzüge bei Langzeitstabilität, Temperaturverhalten und Alterung eines Hochfrequenz-Schwingquarzes und andererseits den wesentlich niedrigeren Stromverbrauch eines Niederfrequenz-Quarzes erreicht, wodurch die Lebensdauer einer Batterie wesentlich verlängert werden kann. Ein solcher Quarzresonator ist bestens dazu geeignet, in Filmkameras oder Armbanduhren verwendet zu werden.

Abstract: When two workpiece strands (14,16) pass through a roll gap between two grooved working rolls (10, 12) on a roll stand to be rolled, the trailing end of one of them may leave the rolls to change the roll gap. At that time screw-down devices (20, 22) on each side of the roll stand are controlled to adjust the roll gap at least at the position of the remaining workpiece. Also in a multi-strand tandem rolling mill, rolling speeds on roll stands upstream of a roll stand from which one of the strands has departed are changed by a speed ratio of (1-b 2 )/(1-b 1 ) where b, and b 2  designate the rates of backward slips in the presence of the two strands and in the absence of one of the strands on the last-mentioned roll stand. Alternatively roll speeds on roll stands downstream of that roll stand may be changed by a speed ratio of (1 + f 2 )/(1 + f 1 ) where f 1  and f 2  designate the rates of forward slip which correspond to the b 1  and b 2  respectively.

Abstract: A coating bath (18) and a process for electrophoretically depositing a forging lubricant precoat (52) on the surface of a titanium workpiece (12) has a specific resistivity in excess of about 400 ohm-centimetres in order to retard simultaneous anodization of the titanium during the electrophoretic deposition process. A high lead, moderate silicate, low alkali metal oxide frit is used in suspension in the bath. Advantageously, the bath also includes an anodic electrocoating resin in colloidal dispersion in the bath. By controlling the degree of anodization and preanodization of the titanium, the thickness of the deposited forging lubricant precoat (52) can be closely controlled.

Abstract: An optical measuring system for measuring in situ by means of one or more fiber-optic probes reflection absorption fluorescence, phosphorescence and turbidity of a fluid or (for all but the last measurement) of a fluid-solid interface. High intensity pulsed light is conveyed to the measurement site by a fiber-optic cable and is given a specific direction at the site by means of the geometry of the probe, reaction light resulting from the stimulating light pulse is discriminated by the geometry of the probe, or another probe, and is returned via a further fiber-optic cable to a measurement system which is enabled to sense the returning light only for the duration of the light pulse. The measurement system comprises means for sensing the relative intensity of the stimulating light pulse and for deriving a signal at least representative of the ratio of the magnitude of the quality sensed, by means of the probe, and the relative intensity of the stimulating light pulse. In one embodiment a unitary probe has three light channels, one conveying light to the site, one conveying light to the measurement system at least representative of the stimulating light intensity at the side and the last providing to the measurement system a signal representative of the magnitude of the quality of interest.
