The mould cavity includes ventilation holes (11) leading therefrom, each covered by a perforated metal plate (7) flush with the interior mould surface (9); the plate is thin (e.g. 1mm) and has small holes (10) or passageways extending therethrough (e.g. 0.1 mm diameter). The plate may be supported as a result of being a press-fit in one end of the ventilation hole or as a result of being supported...

An optical curve follower (2) scans the line drawing (3) located on a bench (1) by means of angle coders and feeds the corresponding digital scanning values to a computer (4), where they are processed and stored. A perforated strip (6) is prepared via a sheet writer (5). This perforated strip (6) is processed by the control section (8) of a control unit (7) and thus serves for controlling a two-ax...

PURPOSE:To increase the amount of information to be written by using a system in which discriminating codes are magnetically written in a magnetic elastomer part previously mixed with a magnetic powder in a method of discriminating manufacture data for tire. CONSTITUTION:A thin rubber sheet 5 previously mixed with a magnetic powder is bonded with the tread 2 or side wall 3 of a tire 1 and integral...

A ski release side clamping binding with hinged jaw members is described. In the binding there is provided a housing. In the interior of the housing there is movably mounted a pair of housing mounted plate members. To each of the housing mounted plate members there is pivotably attached a jaw member. Coupled to the jaw member is a resilient clamping member. The resilient clamping means is provided...

Process and apparatus for providing digital data indicative of the contour of a leaf-like article, e.g. a tobacco leaf, and the flaws (holes) that it may comprise, from a video signal composed of image lines. The video signal is coded by comparing same with thresholds so as to detect transitions. The number n of points pertaining to a hole is compared with a threshold n1, firstly within a line X, ...

BUTEE AVANT DE SECURITE POUR SKI.

CETTE BUTEE COMPREND UNE PIECE DE VERROUILLAGE FIXE 5 PRESENTANT UNE RAMPE INCLINEE 6 ET UN CORPS DE BUTEE 4 ARTICULE AUTOUR D'UN AXE TRANSVERSAL 3; LA MACHOIRE 8 DE RETENUE DE LA POINTE DE CHAUSSURE EST MONTEE MOBILE DANS LE CORPS 4. UN SYSTEME ELASTIQUE 19-18 AGIT SUR LA MACHOIRE 8 POUR APPLIQUER LA TIGE TRANSVERSALE 14 PORTEE PAR CELLE-CI CONTRE LA RAM...

The means includes a layer which comprises a multiplicity of preferably spherical floating bodies with eccentric centers of gravity and which floats on the surface of the beer wort or the new beer or the beer. As a result of their eccentric center of gravity, the floating bodies maintain a stable floatation position and both the floatation foam which is formed during floatation of the beer wort an...

In a system for recovering data, both prerecorded (e.g. servo track) and user data, from a reflective optical data storage medium, with the further capability of distinguishing data from foreign particulate matter on a data disk 65, a pair of detectors 71, 77 measures the fraction of light 73 (e.g. infrared laser light) reflected from and the fraction of light 75 transmitted through the data disk ...

An admixture for Portland cement compositions and particularly Portland cement concrete compositions which contain pozzolans such as fly ash and blast furnace slag is described which is a mixture containing at least three specified chemical ingredients. The admixture improves the strength and other properties of the compositions.

A driving wheel is fixed on a shaft without the use of a key. The wheel (e.g. a sprocket 30) and a locking ring (e.g. the inner race 6 of a bearing 4 in which the shaft is journalled) have bores fitting the shaft and mating peripheral surfaces 24, 22 which are eccentric relative to the bores. Transmission of torque through the wheel and shaft automatically binds the wheel and shaft against each ot...

This device comprises a resilient stress-responsive member interconnecting two conduits which can be respectively coupled to upper and lower portions of the downhole assembly, and are surrounded by a protecting sleeve making up with one of said conduits, the lateral walls of an annular space. Annular elements secured to a first of said lateral walls, and slidable on the second of said lateral wall...
