The invention relates to the optical control of sufficiently transparent bodies, in particular articles such as bottles (B) or flasks distributed in line on a horizontal table conveyor in front of the apparatus, each light emitter (21) of which can be reduced to a simple screen providing a luminous background. Rapid electronic examination is carried out by lines, in the direction of motion ov...

The conventional soft iron parts and insulating parts of the motor unit (1, 7 and 9) of an electromagnetic relay are replaced by moulded plastics parts loaded with magnetic material having a magnetic permeability similar to that of the iron part they replace and having a high electrical insulation. Cheaper and more efficient relays can be manufactured in this way.

Date Jun. 18, 1987.A thread meter comprising a holder for a thread reel, a counter provided with a rotary measuring wheel and guides for a thread, and an outer casing for enclosing said details. The invention is characterized in that a first guide (19) for a thr...

In a method and a device for piecing a thread on a spinning unit for pneumatic spinning, provision is made for advancing a splicing device at least to the thread end delivered by a delivery unit and running into a take-up device, this thread end being inserted into the splicing device as a result of the advancing movement of the latter.

In the case of a process for the splicing of the ends of two double yarns during a piecing operation at a spinning unit, it is provided that either the ends to be spliced are prepared such that the spliced point is a thin point, or that the spliced double yarn is pneumatically strengthened in the area of the spliced point.

A method for the production of a cavity in a piston (23) is described. The method comprises the steps of forming a porous body around an element which has the shape of the desired cavity (17), heating to a temperature such that the element melts and infiltrates the porous body at least in the immediate vicinity of the resulting cavity. The article may then, for example, be incorporated into a pist...

Produced by a method comprising laminating a biaxially oriented copolyester resin film having specified characteristics, to one or both sides of a surface treated metal sheet, which has been heated to the melting point of the copolyester resin film +/- 50 DEG C, just before lamination of the copolyester resin film, the film having been precoated with a resin composite containing in its molecular s...

The conveying device has an electrically driven conveying vehicle with an upright steering rod and a guide carriage guided by overhead guide rails which have power rails and run at a prescribed distance above the floor (which has no rails). The carriage is supported by the steering rod and guided by rollers in the guide rail, being steerable by means of a control device over switches and crossings...

A receiving apparatus for use on handling devices, having a receiving belt which circulates about a supporting body (2) is proposed, which apparatus makes the direct receiving of any desired goods, in particular from plane surfaces, possible. The receiving apparatus is distinguished by a structural shape which is simple to manufacture and advantageous in use. This is achieved in that the supportin...

Endotracheal tube for anaesthesia which is designed - in particular for paediatrics - without tracheal cuff. In order to make it more difficult for anaesthetic gas to flow out, the tube is provided with a suction orifice in the pharyngeal region. Moreover, a flow obstacle can be provided above the suction orifice.

The present invention relates to a remote actuator for a piece of equipment, operating by variation in the flow conditions of a possibly incompressible fluid, comprising an actuating piston (12) and a nozzle-needle unit (20, 21; 53, 57). This actuator is characterised in that one of these two elements (20, 21; 53, 57) is mounted so as to slide in the said piston (12), and in that it comprises mean...

The present invention relates to a method and apparatus for the remote control of at least one piece of drill-string equipment from an instruction transmitted from the surface. The method according to the invention involves the following steps - transmission from the surface of a first information sequence conforming to a predetermined sequence, - detection of a second sequence resulting from th...

A method for preventing the driving wheels of a motor vehicle with a mechanical gearbox from slipping consists of detecting the rate of rotation of the vehicle's engine, the speed of the vehicle, the angular velocities of the driving wheels and the gear ratio engaged, and obtaining corresponding signals indicative of the parameters detected. By means of these signals, the rate of rotation of the d...

A brake actuator has a housing (7) containing tappets (13, 14) operable by a cam (8) to apply brake shoes (5, 6) against a rotary brake drum. The housing defines a cavity to which lubricant is admitted through means (17). A non-compressible flexible element (30) is disposed within the cavity and subject to lubricant pressure. The element (30) is movable during outward movement of the tappets to co...

At least one of the gears of a pair of meshing gears with constant tooth spacing has irregularly distributed, variously-sized, limited deviations ( DELTA b, DELTA da DELTA s, ...) from the standard shape of the teeth (Z1, Z2 ...), so that single-frequency vibrations do not occur and the total gear noise is substantially reduced. The irregularities may take the form of variations in the tooth tip...

A brake caliper 6 which engages around a brake disc and brake shoes, is slidingly mounted on a brake carrier 5 by means of a pin 2 and is provided with piston 1, the piston 1 and/or pin being equipped with nonmetallic nonorganic materials 3 e.g. coatings of ceramic or enamellar materials in the sliding surfaces. The coatings may be applied to the sliding surfaces by means of plasma spraying.

In a method of producing a gas containing carbon monoxide and hydrogen, in which method the gas does not need to be subjected to energy-consuming and costly scrubbing steps before being used as reduction gas, combustion gas or synthesis gas, the gas is produced from material containing carbon and/or hydrocarbon and oxidant and is supplied to a reaction chamber (2) simultaneously with a gas heated ...
