A drum brake comprises two brake shoes (4,5) which are operable hydraulically and/or mechanically. A first brake shoe (4) is supported trailingly in forward travelling direction and leadingly in backward travelling direction. In the forward travelling direction both brake shoes (4,5) are supported trailingly so as to obtain soft response behavior. And a lever (7) is supported at the second brake s...

A rotatable drum (1) carries, and is driven by, a gear rim (3), with bevel toothing (12), via a flexible frustoconical casing (5) which accommodates distortions of the drum and absorbs axial loading resulting from the bevel toothing. Flexing of the gear rim is resisted on one side by the stiffness of the casing (5) and on the other side by a stiffening ring (9).

For the preparation of a building and/or construction material a polymer modified, aqueous dispersion, containing amorphous silicon dioxide and at least one polymer, is mixed and reacted with at least one inorganic binder, and occasionally with at least one aggregate, and hardens thereby. The polymer modified, aqueous dispersion contains amorphous silicon dioxide and at least one polymer. This pol...

A memory for storing data in a computer system. Integrity of data transferred to or from a memory array is monitored by transferring two sets of EDC or ECC data corresponding to a longword of data between the memory array and two separate memory controllers. The probability of an undetected error is very low because the two sets of EDC or ECC data are compared to ensure that they match. The number...

A container has a removable multi-bed, water purification filter with two beds or compartments that are separated by a fibrous member. The multi-bed filter reduces lead, aluminum, chlorine, or the like, from water. The container has upper and lower chambers with the multi-bed filter therebetween which permit a batch filtering of water in response to a gravity feed so that water pressure is not req...

An endoscope device includes an endoscope tube having a forward head piece and a flexible eversion tube for moving the head piece into a channel-like body cavity by means of fluid pressure. The eversion tube has an outer portion; a turning portion engaging the head piece; and a rearwardly extending inner portion. A first fluid pressure is exerted in a space between the outer portion and the inner ...

-17- EL-0278 A multilayer interconnect comprising a ceramic substrate, a patterned conductor layer, a layer of acrylic or acrylate adhesive, an organic insulating film, and a metal foil layer. Active electrical components can be soldered onto the metal foil layer. These circuits are particularly useful in under the hood automotive applications.

Resets on a data processing system are targeted to specific locations of that processing system and have different effects. Some resets are transparent to instruction execution while other resets will interrupt the normal execution of instructions. In addition, in a multi-zone environment resets in one zone do not automatically propagate to the other zone; instead, each zone generates its own rese...

A process for transferring information including a source or destination address between two nodes in a network via data switching logic. The switching logic must decode commands and addresses in order to adopt the proper configuration so that the command and addresses can be forwarded from one system resource to another system resource. A read or write address is transmitted to the switching logi...

T 5986 CONTAINER FOR ELASTIC SOLID MATERIAL A container for elastic solid material, comprising connecting means for detachably connecting adjacent walls of the container. The connecting means include a protrusion attached to a first wall and a guiding element attached to a second wall adjacent to the first wall. The guiding element is provided with an opening through which the protrusion is extend...

The cargo type air-ground missile (3) is released in order to follow a nominal trajectory (4). The missile includes a head (5) which contains the electrical components controlling ejection of sub-missiles (9), the main body (6) which holds the sub-missiles, and a rear propellant section (7) with stabilising fins (8). The sub-missiles are ejected from the hold in a 'depositing' operation controlled...

A container has a removable multi-bed, water purification filter 30 with two beds or compartments 62, 64 that are separated by a fibrous member. The multi-bed filter reduces lead, aluminum, chlorine, or the like, from water. The container has upper and lower chambers 26, 12 with the multi-bed filter therebetween which permit a batch filtering of water in response to a gravity feed so that water pr...

A magnetoresistive (MR) read transducer assembly in which the thin film MR layer is longitudinally biased only in the end regions by exchange bias developed by a thin film of antiferromagnetic material that is deposited in direct contact with the MR layer in the end regions. The longitudinal bias is of a level sufficient to maintain the end regions of the MR layer in a single domain state and ther...

A carbonaceous feedstock, e.g. coal or heavy oil, having a low hydrogen to carbon atomic ratio is partially oxidised using air, or oxygen enriched or depleted air, to form a crude gas which is subjected to catalytic shirt and excess steam removal. Carbon dioxide and nitrogen are then removed from the resultant raw gas, which has a hydrogen to nitrogen, plus carbon monoxide, volume ratio in the ran...
