Abstract: The present invention relates to a process for the production of moulded articles which have an unfoamed vinyl chloride homopolymer, copolymer, terpolymer or graft polymer layer (compact layer) produced by slush moulding over a layer having at least one foam structure. To produce the unfoamed layer, a plasticiser-containing vinyl chloride polymer is first introduced into a mould in the slush-moulding process, and gelled or sintered by heating. After the compact layer has formed, any excess of ungelled or unsintered powder, plastisol or paste is removed from the mould. According to the invention, sintering or gelling of the compact layer is followed by application by slush moulding of a plasticiser-containing vinyl chloride homopolymer, copolymer, terpolymer or graft polymer which contains at least one water-free chemical blowing agent, this barrier layer being formed using a mixture of 100 parts by weight of vinyl chloride polymer, certain parts by weight of at least one plasticiser (monomer plasticiser and/or polymer plasticiser), at least one stabiliser and/or kicker for the blowing agent (including antioxidants), at least one water-free chemical blowing agent or blowing agent mixture and at least one filler or filler mixture and/or additive.

Abstract: For the underground replacement of damaged sewage pipes of inaccessible diameter and into which house connection pipes lead, a method making it possible to work completely underground is described. In a first working step (a), each house connection pipe (2) is first cut off through one or more radial separating lines from the old sewage pipe (1) by means of a separating device which can travel in the old sewage pipe (1) and be inserted through the mouth opening. Subsequently, in a process step (B), a boring device which breaks open the old sewage pipe (1), followed by pipe sections forming the new sewage pipe are prepressed from a pressure shaft through the old sewage pipe. When the old sewage pipe (1) has been replaced over the intended length by the new sewage pipe, according to a further process step (c) a sealing compound which joins the sewage pipe to the house connection pipes (2) and hardens approximately in the shape of a tube is introduced, by means of a shaping and pouring device which can travel in the sewage pipe, through lateral connection openings. <IMAGE>

Abstract: In the opened state, the clamping ring (6) has no parts which connect its two end portions (6a, 6b) to one another, that is to say no clamping device consisting of a clamping lever and connecting lever. As a result, it is less expensive in manufacture than a clamping ring fitted with a clamping device. This is therefore very advantageous because the clamping rings are usually no longer used after the initial opening of a container, but thrown away. Serving for securing the ring in the closed state are a releasing mechanism (8), constructed as a lug, at one end portion (6b) of the ring and a corresponding opening (7) at the other end portion (6a), in the closed state the lug (8) being thrust through the opening (7) and secured in this position by a securing pin. For closing a clamping ring of this type, an inexpensive closing device can be used. <IMAGE>

Abstract: In the letterbox colour television system, additional data are transmitted with an appreciably reduced amplitude for reasons of compatibility, low frequency components having a relatively high amplitude. This results, however, in a reduction in the signal-to-noise ratio and disturbances in synchronization occur in known television receivers. The amplitude of the additional data can be increased without the disturbances in synchronization that occur in known television receivers if the additional data are transmitted in the form of a vestigial sideband modulation of the colour carrier. The frequency response of known IF filters can be exploited advantageously to form a Nyquist flank on the colour carrier. If the phase used is a constant V-phase of the colour carrier, any disturbances in the compatible reception are advantageously slight.

Abstract: In motors or the like, for example, the arc, especially commutator sparking, and/or a replacement criterion is detected at the connecting terminals and evaluated with reference to predetermined characteristics. According to the invention, either the motor current is measured and the high-frequency component generated by commutator sparking is evaluated from that or the high-frequency components are decoupled at the connection terminals of the electric motor and capacitatively short-circuited. Alternatively, high-frequency stray currents flowing from the connection terminals to the casing can be detected and capacitatively short-circuited. The individual measuring arrangements therefore essentially comprise an h.f. current transformer (10), the signal from which is taken to an evaluating instrument (12, 22, 32).

Abstract: In order to prepare physiologically tolerated water-soluble starch esters, the invention proposes that starch is converted by acid hydrolysis or enzymatic hydrolysis to a partially hydrolysed form with a mean molecular weight in the range from 10,000 to 500,000 Daltons. This partial hydrolysate is then acylated, in aqueous solution, with the anhydride or halide of an aliphatic monocarboxylic acid with 2 to 4 carbon atoms or an aliphatic dicarboxylic acid with 3 to 6 carbon atoms, or mixtures thereof, and an alkalinization agent, to give a product with a substitution ratio in the range from 0.1 to 1.0 mole/mole. Salts are removed from the resulting reaction mixture. The starch esters thus obtained are highly suited for clinical use, in particular parenteral administration and administration in the diet.
