Abstract: A flameproof linear polyester is described containing, copolymerised in the molecule, a phosphorus compound of formula:
     where R is a hydrogen atom, an alkyl group with 1 to 4 carbon atoms or a hydroxyalkyl group, and R' is a hydrogen atom, a hydroxyalkyl group or the group -(CH 2 CH 2 0) n H, where n varies from 1 to 4. Said linear polyester is prepared by firstly forming a low molecular weight precondensate from a dicarboxylic aromatic acid (or a relative lower alkyl diester) and an alkylene glycol, and then polycondensing in the presence of said phosphorus compound, in such a quantity as to obtain a content of phosphorus (expressed as the metal) in the linear polyester of between 0.4 and 0.8% by weight. The linear polyester thus obtained can be formed into articles such as fibres, film, sheets and other articles which, besides being flameproof, possess improved dyeing characteristics. A process is also described for preparing the phosphorus compounds corresponding to the aforesaid general formula, where R is hydrogen or an alkyl group containing 1 to 4 carbon atoms, and R' is hydrogen. Said phosphorus compounds are prepared by reacting phenylphosphinic acid or ester with paraformaldehyde, at a temperature of between 60 and 150°C.

Abstract: A variable mechanical advantage/variable effective length shifting mechanism (30) is provided, preferably for shifting a synchronized positive clutch transmission. A compound mechanism comprises a first member (34) in the form of a variable mechanical advantage/variable effective length first class lever having a first lever portion (34), a second lever portion (42) and a fixed pivot axis (38), and a second member (44) in the form of a second class lever pivotably mounted about a pivot axis (70) extending substantially parallel to and spaced from the first pivot axis. A pivot pin (48) extending substantially parallel to the first and second pivot axes is slidably received in axially extending slots (46 and 84) provided in the first and second members, respectively. A resilient biasing member (58) is provided for resiliently biasing the pivot pin axially away from the first pivot axis and axially toward the second pivot axis. The pivot pin may overcome the bias of the biasing member to move toward the first pivot axis and away from the second pivot axis to increase the mechanical advantage of the compound mechanism by increasing the mechanical advantage of both the first class lever member and the second class lever member.

Abstract: A programmable sweep generator for generating a linear ramp signal of different slopes in a predetermined step sequence is disclosed. @  The programmable sweep generator comprises a controllable voltage generator, a voltage-to-current converter, and integrator sections. The slopes of the ramp signal may be electronically controlled by switching the controllable voltage generator, voltage-to-current converter and timing capacitors in the integrator section. The use of independent buffer amplifiers, independent control circuits, and current steering devices for each timing capacitor eliminates the need to connect a switching element in series with each timing capacitor, thereby eliminating any error or non-linearity.

IPC: B28C5/38

Abstract: A process for the preparation and immediate use in situ of ready to use blends of structural material, such as plaster, mortar, stucco, tile adhesive or similar blends, which, in contrast to the usual methods does not use as a raw material a dry mixture of the three main components binder, filler and additives. Instead a dry mix of binder and filler is prepared at the building site, and an aqueous solution of the additives is added in a separate mixing operation, immediately followed by the application in situ of the finished blend. This method avoids the difficulties associated with the use of dry mixtures containing all three components. The invention includes an apparatus for mixing and immediate application of the blends as defined by the process claims. In an especially advantageous form of the invention, part of the aqueous solution of additives is added to the rest of the blend, after mixing and preferably at a point situated between the conveyor pump and the transport hose, in the form of a cylindrical thin concentric mantle surrounding a core of the wet blend. Much of the friction between the structural blend and the transport conduit can thus be avoided, as well as the wear associated with it. The application of the structural blend can be assisted by pressurized air injected into the stream upstream of the applicator nozzle. The stream of air may be loaded with airborne particles of silicone solution in order to impart water repellency to the structural layers made by the process.

Abstract: The acoustical measuring device consists of a measuring probe which is immersed by means of a cable in the bore hole filled with drilling medium and can be moved in the axial direction therein. The measuring probe contains a transmitter which emits pulses. The echo signals are detected by a receiver fitted in the measuring probe. To detect the geophysically particularly important casing waves, which are received as strong useful signals undisturbed by transient and decay processes, the effective distance between transmitter and receiver in the measuring probe is smaller than half the wavelength of the signal transmitted in the drilling medium. This involves a reflection arrangement of essentially axial oscillators which are broad-band but prefer the lower acoustical frequency range. The measuring time of the sonograms received (microseismograms) is up to about one second.

Abstract: A tubular heat recoverable article has two layers in thermal contact, one inside the other. The two layers have appreciably different recovery temperatures. Shrinking of the article on to a substrate is effected by applying heat to the outer layer (1) of higher recovery temperature such that conduction to the inner layer (2) of lower recovery temperature ensures that the inner layer (2) reaches its recovery temperature, and thus becomes elastomeric, before the outer layer begins to recover. The article, which may be used in an electric power cable splice, thus combines good storage life with good recovery time.
