Abstract: An emergency lock safety belt retractor is designed to facilitate release from an inadvertent lock-up which may occur after full-speed retraction of the seat belt. This undesired lock-up is due to a latch mechanism which locks a belt spool in response to either excessively abrupt onset of extraction, such as may occur in front-end automotive accidents, or excessively abrupt cessation of retraction. This latch mechanism has two separate latches: a simple latch pawl biased away from its latched position and a more complicated lock wheel. The latch pawl is mounted on a rotary drum and in its latched position engages teeth on a stationary drum. The lock wheel is coupled for rotation with the belt spool but is free to move axially through three regimes. The lock wheel is biased toward a first axial regime in which it couples the rotary drum to the belt spool.

Abstract: A method of making cheese-like food by mixing a proteinaceous component and a fat or oil component, curdling the resulting mixture with a microorganism and/or an enzyme to form a curd, cooking the curd to separate the whey, draining the whey, adding salt, and then working up the resulting material without or with a ripening step for a short period of time is disclosed. The improvement resides in using a fat or oil component selected from the group consisting of rapeseed oil; a mixture of rapeseed oil in combination with one or more oils such as laurin fats or oils and other edible oils such as soybean oil; a mixture of rapeseed oil and said other edible oil, or a mixture of said laurin fat or oil and said other edible oil; said fat or oil having a solid fat index determined by a pulse nuclear magnetic resonance method of 20 to 55 at 10.degree. C., 10 to 45 at 20.degree. C., 25 or less at 30.degree. C. and 10 or less at 35.degree. C.

Abstract: Conventional discharge tubes comprise electrodes within a separate containing vessel. The electrodes are joined to an external circuit by electrical conductors which pass through the vessel wall via an insulated side arm. Such a construction has disadvantages in that careful manufacture is required and it is also difficult to produce a desired distribution of the active medium in a laser and maintain a stable optimum temperature. In an attempt to reduce these problems the invention provides a discharge vessel which comprises electrical conductors and insulators arranged alternately so that a separate discharge vessel is not required. Since the discharge vessel is partially thermally conducting, temperature control is facilitated by its fast response to stabilizing controls, heat being supplied from an external source.

Abstract: In a perforated plate (1) for evening out the velocity distribution in a flow channel, the passage holes (2) are designed as shock diffusers arranged in parallel. For this purpose, they are provided with an inlet diameter (d) on the inflow side (3) and with a larger outlet diameter (D) on the outflow side (4) of the perforated plate. Due to this design, a relatively large blocking (area ratio of blocked flow cross-section to the free flow cross-section) on the inflow side and a relatively small blocking on the outflow side of the perforated plate are obtained. To ensure a shock diffuser effect, the length of the outlet holes must be sized such that the flow makes contact again before the outlet edge thereof. Important advantages of this perforated plate are that, with a relatively low pressure drop coefficient, a very good evening-out effect and a short back-flow zone on the outflow side of the perforated plate are achieved.

The handle shaft projects outwardly relative to the reel body, and the handle is supported on the handle shaft at an intermediate portion thereof, with the handle shaft also projecting outwardly relative to the handle. The handle is interposed between the reel body and the drag mechanism.

Abstract: A compressed-gas breaker having a magnetic coil through which the breaking current flows, has two coaxial contact members which are movable with respect to each other along a central axis and have in each case one arcing contact. The arcing contacts are surrounded by a heating chamber which is joined to the arc volume located between the separated burning contacts during breaking. In this breaker, the breaking capacity is to be improved by a simple means. This is achieved by the fact that between the heating chamber and the arc volume a gas-guiding device is provided which has at least three ducts which are arranged to be distributed azimuthally around the axis. These ducts have sections which open radially with respect to the axis into the arc volume. Such a breaker can be used preferably for the switching of large current of medium-high voltage.

The organic matrix material is selected from the group comprising epoxide resins, alkyd resins, polyurethanes, silicone resins, unsaturated polyester resins and acrylates.

Abstract: Two cutting tool inserts are fastened at each side of a cutting tool insert holder to have their active primary cutting edges aligned. A third cutting tool insert is displaced in relation to the other two cutting tool inserts in the cutting direction such that its active primary cutting edge overlaps in extent the active primary cutting edges of the two aligned cutting tool inserts. This produces an effective total length of the cutting edges which corresponds to the sum of the edge lengths of the three cutting tool inserts less the two overlapping regions. Should one of the cutting tool inserts chip or break off in the region of the overlapping active primary cutting edges, the planing or shaping of hardened gear tooth flanks of a roughed-out gear blank or workpiece can nevertheless be continued since such chipping of the cutting edge has no detrimental influence on the workpiece due to the overlapping.
