Abstract: The tubular framework (1), which is suitable, in particular, for a chair (2), has two lateral support parts (4) and a plinth part (3) which connects said support parts and the connection portions (5) of which are inserted telescopically in coaxial longitudinal portions (9) of the support parts (4) and are secured in position in a suitable manner. In this case, the longitudinal portions (9) of the support parts (4) merge via bend portions (10) into upright support portions (13), the openings (14) for insertion of the insertion ends (6) being provided on the outsides (11) of curvature of the bend portions (10) and being produced by the fact that, from the free end (16) of the respective longitudinal portion (9), a drill, which is adapted to the inside diameter of said longitudinal portion, is inserted and used to pierce the wall of the bend portion (10) from the inside of the tube. Thus, with extremely simple production, there results a compact and stable tubular framework (1) which can be constructed in an advantageous manner so as to be stackable. <IMAGE>

Abstract: Oxidation of alcohols to ketones using bromine suffers from a side reaction of comparable speed in which a bromide substituted product is formed. Additionally, the use of bromine as reagent is relatively unpleasant and it creates a major waste disposal problem. 
     The latter problem can be solved by generating bromine in situ by reaction between hydrogen peroxide and bromide ions or hydrogen bromide, but this inevitably increases the exposure of the alcohol to HBr/Br⁻. The selectivity of the process towards non-substituted oxidation depending upon the inherent deactivation or reactivity of the alcohol can be improved by irradiating the reactants with light of suitable frequency to generate bromine radicals in the mixture, and/or by controlling the rate of introduction of the hydrogen peroxide and controlling the extent to which mole ratio of HBr:alcohol is substoichiometric. Selectivity can also be improved by employing a two-phase reaction mixture, the alcohol being present to a considerable extent in the organic phase with HBr/Bromide being retained to a great extent in the aqueous phase. 
     It is particularly beneficial for the selective oxidation of alcohols that are substituted by adjacent electronegative groups, for example chloropropanols.

Abstract: A counterfeit detecting method and apparatus are provided for detecting the authenticity of an article having a label containing an isotope of a chemical element enriched to a predetermined amount. The apparatus comprises a housing, a source of gamma radiation positioned in the housing, and a gamma radiation detector positioned in the housing for detecting the radiation from the source. The gamma radiation source is selected to emit radiation which can stimulate a selected nuclear transition in the label material in the unknown manner of the Mossbauer effect. Structure is provided in the housing for receiving the article and positioning at least a portion of the article in the housing such that the label is positioned between the source and the detector. A vibrating member vibrates the source such that the frequency of the gamma radiation therefrom is shifted. A calculating device, such as a microprocessor, is coupled to the detector for calculating the ratio of the number of gamma rays counted by the detector during a predetermined period of time when the article is not in position near the receiving member (N O ) to the number of the gamma rays counted by the detector during a period of time equal to the predetermined period when the article is positioned near the receiving member (N R ), and for calculating the ratio of the number of gamma rays counted by the detector during the period of time when the article is not in position near the receiving member (N O ) to the number of gamma rays counted during a period of time equal to the predetermined period when the source is vibrated by the   vibrating device (N E ) and for calculating the ratio (N R /N O )/(N E /N O ) and thus N R /N E . An output device provides an output indicating whether or not N R /N E  and N E /N O  are within a predetermined range. The method comprises steps of counting the number of gamma rays received from a source of gamma rays by a gamma ray detector during a predetermined period of time (N O ) and then placing the article between the source of gamma radiation and the gamma radiation detector. The gamma rays received by the detector are counted for a period of time equal to the predetermined period of time (N R ) and then a relative vibrating movement is established between the source and the detector. The gamma rays received by the detector are again counted for a period of time equal to the predetermined period of time while there is relative vibrating movement between the source and the detector (N E ). The ratios N R /N O , N E /N O , and N R /N E  are calculated, and then an indication is provided as to whether the ratio N R /N E  and N E /N O  are within one of several predetermined ranges. 
     Also, the present invention is directed to an article capable of being authenticated, in which the article comprises a metallic body and a label fixed to the body. The label includes an isotope of a chemical element enriched to a predetermined amount.

Abstract: In a data transmission system including a central subsystem (10) coupled by transmission lines (20) of different lengths to a plurality of remote subsystems (16), methods and apparatus for synchronizing responses to messages transmitted by the central subsystem (10) to compensate for different line delays are provided. The messages are transmitted by the central subsystem (10) during the first portion of a frame, while the responses are transmitted by the remote subsystems during a second portion of the frame. In each of the remote subsystems (16), a compensation delay equal to a maximum line delay associated with the longest of the transmission lines (20) less an actual line delay (2T D ) associated with the transmission line (20) connected to that remote subsystem (16) is determined. The response to the message is then delayed by the compensation delay (T C ) so that the responses from each remote subsystem arrive at the central subsystem delayed by the maximum time delay (2T M ). The central subsystem (10) detects the response during a detection internal delayed by the maximum time delay (2T M ) after the end of the message.

Abstract: Power semiconductor modules having vertically routed terminal lugs require soldering jigs which position and align the terminal lugs during soldering. 
<??>The invention proposes using the plastic housing (10, 45) itself as soldering jig to avoid expensive soldering jigs. For this purpose, guide channels (11) for the terminal components (12, 41) or further mounting pieces (43, 44) or recesses (47.1, 47.2) are provided inside the housing (10, 45). It is also proposed to manufacture the housing (10, 45) of thermally resistant plastic so that a subsequent soldering is possible, for example even in a continuous furnace. 
<??>The solution according to the invention is particularly suitable for power semiconductor modules having so-called external control terminals (4) since mounting involving two soldering steps is envisaged, with good accessibility still being provided for wire bonding tools after the first soldering and with the terminal lugs (12) and the necessary components (29, 32) for control terminals (4) only being mounted in the second step.

Abstract: A power steering control valve (22) includes relatively rotatable inner (40) and outer (42) valve members. A power steering resistance control system resists relative rotation between the inner and outer valve members with a force which varies as a function of variations in vehicle speed. The power steering resistance control system includes a force transmitting member which is disposed adjacent to one end of an outer valve member. A spring force is applied against the force transmitting member urging it in a first direction along the axis of rotation of the valve members. Fluid pressure is applied against the opposite side of the force transmitting member to urge it in the opposite direction along the axis of rotation of the valve members. A speed responsive control unit, connected with a fluid return conduit for the power steering valve, is operable to vary the fluid pressure applied against the force transmitting member as a function of variations in vehicle speed. At relatively low vehicle speeds, the fluid pressure force applied against the force transmitting member is relatively large and it is easy to actuate the steering control valve. As vehicle speed increases, the fluid pressure force applied against the force transmitting member decreases and the resistance to actuation of the steering control valve increases.

Abstract: Graft polymers in which vinyl carboxylates and optionally further ethylenically unsaturated monomers are grafted polymerically onto polyurethane backbones by free-radical-initiated graft polymerisation, and products of the hydrolysis of the graft polymers, can be obtained by grafting vinyl carboxylates having 3 to 20 carbon atoms and optionally further ethylenically unsaturated, polymerisable and optionally copolymerisable monomers in amounts of from 10 to 99% by weight, based on the graft polymer, onto a polyurethane backbone containing at least 2 urethane groups in the molecule, and, if desired, subsequently partially or fully hydrolysing and/or alcoholising the vinyl ester units and any further hydrolysable monomer units in the grafted-on polymer radicals of the graft polymers. Vinyl esters which are preferred for grafting are vinyl acetate and/or vinyl propionate and possibly vinyl versatate. The graft polymerisation is carried out in solution or in bulk and can also be carried out in emulsion or suspension. Unhydrolysed graft polymers are suitable, inter alia, as adhesives, in particular as hot-melt adhesives. Fully and partially hydrolysed graft polymers are suitable, inter alia, for the production of films. Depending on the polyurethane backbone, the degree of grafting, the degree of hydrolysis and the type of grafted monomers, the graft polymers, compared with polyvinyl alcohol, can have significantly lower melting points, and are thus advantageously suitable for the production of pressed or extruded films under mild temperature conditions without the additional use of organic plasticisers. Hydrolysed graft polymers are furthermore suitable, inter alia, as adhesives.
