Abstract: A device for control and monitoring of pressure in a system combines a conventional three pole pressure switch with the following additional features: (1) a lock mechanism with three influencing input factors and a single resulting output contact action, (2) a three pole thermal release device as one of the input factors, and (3) a remote control tripping device as another input factor, all integrated into a single, compact, modular unit. The thermal release device comprises a plurality of bimetals which sense electrical flow passing through the device, and which are mechanically connected to a locking mechanism to shut off current if the electrical flow reaches a predetermined maximum. If any of the three inputs activates the locking mechanism, the device must be reset by an operator.

A metallic plate-like upper ball cup between the ball and the cover is separate from and out of contact with the lower ball cup and has cutouts defining at least one portion bearing resiliently upward on the cover and at least one portion bearing resiliently downward on the ball.

Abstract: An electrical connector system which has several independent housing sections. Locking elements are formed onto a first housing section and extend through openings into the retaining chambers of an adjacent housing section. In order to create an electrical connector system which, starting from one housing section, is capable of being extended in various different ways through the connection of further housing sections, one of the independent housing sections is formed as a central housing. At least two other housing sections which are directly allocated to it are formed as satellite housings. The locking elements formed onto the central housing engage on the one hand in the retaining chambers of the first satellite housing and on the other hand in the retaining chambers of the second satellite housing.

Abstract: The anchoring cartridge for anchoring a fastening element in a drilled hole has two chambers. One chamber contains from 1.0 to 10% of a hardener component dissolved in a mixture of styrene and an unaccelerated radical-curing resin and the other chamber contains an accelerator mixed with another mixture of styrene and unaccelerated radical-curing resin. By including unaccererated radical-curing resin in both chambers a homogeneous curing of the components is ensured.

Abstract: A method and apparatus for testing an elongate product for faults and defects, which comprises a rotatable testing head which permits the elongate product to be passed coaxially therethrough and which mounts a pair of testing probes so as to permit adjustment of their operating diameter. In order to automatically adjust the positions of the probes to accommodate elongate products of different sizes, there is provided an external adjustment unit, which stops the testing head in a predetermined angular position. The adjustment unit contains an external adjustment drive and when the rotation of the testing head has stopped, the external adjustment drive is advanced into operative engagement with the adjustable mounting of the testing probes.

The casing shell of at least one casing section (8, 9) is composed of an outer, continuous shell part (24, 25) and of at least two separate inner shell parts (19-22) with respective associated inner-wall parts (12-15). The outer and the inner shell parts are expediently connected firmly to one another, especially by shrink bonding.

Abstract: A device for packing packs of filled tea bags has a channel for collecting filled tea bags to form a stack. The channel has a first stack holder for securing the leading tea bag and a first stack pusher for advancing the completed stack. A rotary device has two cassettes for receiving the completed stack. A transporting device has a second stack holder and a second stack pusher for transporting the completed stack from the rotary device after rotation into a position above the box for packing. A pushing device for pushing the completed stack into the box is provided. A tea bag feeding device feeds individual tea bags to the channel for forming the stack. Two oppositely arranged retaining fingers are positioned at an upstream end of the channel. A tea bag holder is positioned in an initial position at the beginning of forming a new stack at the upstream end of the channel and is displaceable in the longitudinal direction of the channel.

Abstract: A heat insulating container has an inner container body and a sleeve. The sleeve is attached to the circumferential wall of the inner container body by attaching surfaces, and has cut edges extending transversely to the circumferential direction. The attaching surfaces are only arranged extending transversely to the circumferential direction. A simplified application of the sleeve to the circumferential wall of the inner container is thereby made possible and less material and working time are required for production.

Abstract: A measuring device (8) comprises an emitter (9) and a linear array (10) of detector elements (11 to 14). The emitter (9) emits a radiation beam (15) which enters into a narrow face (20) of a panel-like workpiece (7) at an angle (19). The individual rays (1 to 4) of the radiation beam (15) have different length paths (21 to 24) through the workpiece (7) and thus have differently attenuated output intensities. By difference calculations on the output intensities of the rays (1 to 4) thus obtained, one can calculate density values in the narrow face (20) and finally establish a density profile through the thickness (6) of the workpiece (7).
