A vehicle transmission having an auxiliary transmission with high and low speeds connected in series with a multi-speed manual transmission and clutch to an engine wherein the auxiliary transmission normally is shifted in response to the throttle opening of the engine and the vehicle speed. A control device detects the actuation of the clutch to maintain the auxiliary transmission in the low speed...

A binding head for applying binder, e.g. tape or thread, to an optical fibre bundle (A), comprises a rotated arbor (A) carrying a spool (C) of binder. The binder (G) is dispensed from the spool via a lightweight dished free wheeling shroud (D) and a substantially circular brush (K) fixed to the arbor, the binder (G) being dragged across the radial bristles of the brush which thus induces a desired...

A tube of the first metal is formed with a recess in which the second metal is applied. Alternatively, two tube sections of the first metal are spaced end-to- end in a mould and the second metal cast into the space. The composite tube is then machined to its final dimensions. In the preferred embodiment the article is a high pressure tube (Fig. 1) for use in a proportional solenoid operated valve ...

A dental x-ray diagnostic installation comprises x-ray apparatus containing x-ray generator and x-ray tube having a hollow anode in the form of applicator for insertion in the interior of a patient's mouth. In order to facilitate the construction and handling of the apparatus in particular the insertion of the applicator in the mouth, the x-ray apparatus is designed as a unit capable of being posi...

Manufacture of a workpiece from a creep-resistant nickel superalloy which is hardened by means of an oxide dispersion, by a powder-metallurgical process in which the mechanically alloyed powder is subjected to an isothermal or quasi-isothermal hot-rolling operation, in the course of which the powder particles are converted into a flake-shaped form with a pronounced longitudinal axes, and the rolle...

In a bottle inspection machine a cylindrical hollow shaft is driven rotationally about a vertical axis. Another shaft is splined in the tubular shaft for rotation therewith. Another rotor is mounted coaxially to the inner shaft and the two rotors constitute a means for transporting bottles in a circular path. A light source is mounted on the radially outer side of the circular path and projects be...

In a processing plant in which workpieces are conveyed to selected work stations according to a programme, the computer programme chosen for the plant operation and representing a simulated operating schedule is run through during the actual operation of the plant in synchrony with the latter. The plant comprises a number of sensors by means of which data on actual events taking place in the plant...

A replaceable insulating sleeve (20) is disposed around the lower end of a drill string (29) used in drilling a well (30). The sleeve (20) is restrained from rotating relative to the drill string (29), but can be released and quickly slipped off the drill string (29) in the field to permit rapid replacement if damaged, or if alternate equipment is required. The sleeve (20) carries sensing means (3...

A control device in a motor vehicle having a clutch and a transmission for controlling operation of the clutch and the transmission, includes a control lever angularly movable in first and second directions perpendicular to each other, a first connector mechanism interconnecting the control lever and the transmission for enabling the transmission to shift gears therein in response to angular movem...

A machine for de-charring the inside of a used whisky cask (51) comprises a pair of chuck rings (4, 5) for gripping and rotating the cask about its axis while a counter-rotating flapper-type grinding wheel (43) is moved by a longitudinal feed carriage into the cask from one end in a direction which is slightly skew to the cask axis. The longitudinal feed carriage is mounted on a transverse feed ca...

A transparent film of a vinylidene fluoride copolymer, comprising a dry film of a vinylidene fluoride copolymer having a parallel light transmittance of 85% or higher at a film thickness of 30 microns. The transparent film is obtained by forming a mixture of a vinylidene fluoride copolymer having a specifically high molecular weight with a solvent into a film, preferably by casting, and evaporatin...

Caliper brake apparatus has a caliper housing, an actuator including a plunger movable axially longitudinally to urge a lining against a rotating disc, and the lining having the form of a plate which is laterally elongated and defines a plane generally perpendicular to said axis. The apparatus is improved by: (a) the plunger having cross sections in planes normal to said axis and characterized as ...

A resource allocation system for indicating the optimum allocation of a resource between a series of demands iteratively processes the probability data for each demand to determine for each of a range of amounts of resource available the optimum distribution of the resource between the demands and the resultant probability of successfully overcoming all the demands. The system may be used to predi...

A retractable anchoring device for a sonde to be lowered into a well for logging purpose, is adapted to rigidly position the sonde at a preselected depth. The device comprises pivotable anchoring arms adapted to apply against the wall of the well a substantially constant force produced by associated jacks actuated by driving means so as to apply to the respective arms forces which are limited by s...

In a brake actuator device, wear of brake lining, which results in the increase of stroke of the brake actuator device consisting of piston and cylinder, is compensated by an adjuster which functions automatically when the brake is operated.
