The disclosure relates to the protection of solid precursors in powder detergent compositions using a hydrogen peroxide bleach system. The finely divided precursor is formed, with a carrier material, into a composite particle which is then coated. The coated particle gives good dispersion of the precursor in the wash liquor.

Surfaces are protected from graffiti by panels of rotatable rollers. The rollers are rotated in random patterns to scramble or conceal graffiti. The rollers are removed for cleaning.

A covering to protect a handbag and its contents from the rain or the like. The covering is a vinyl sheet sewn to the handbag and stored within a pouch on an exterior panel thereof. When in use, the sheet is unfolded and wrapped around the bag.

A device for protecting the body of an individual from impacts, comprises a first layer 10 of plastics material e.g. polypropylene which acts to protect from impacts the body of an individual wearing the device. To layer 10 is bonded a second layer 12 is of cross-linked polyethylene foam which acts to cushion the body of the individual The outer margin of layer 12 extends beyond the outer margin of layer 10 by between 5 and 20 mm, preferably 15 mm. A third textile fabric, e.g. terry towelling, l...

An improved automatic underride protection actuator for a trailer, the trailer being translatable over a ground surface, includes a rotatable ramp that is shiftable between a ground engaging load/unload disposition when the tiltable bed is in the load/unload disposition and an underride protection disposition when the tiltable bed is in the transport disposition. The ramp underride protection disposition is a disposition in which the ramp depends from a tiltable trailer bed the ramp and is rotat...

A spinal protection device is provided which minimizes the formation of post-operative adhesions. The protection device may comprise a fenestrated shield, and may be positioned such that contact between the shield and the spinal dura is substantially avoided.

A method and system for detecting a potentially destructive state of an arrangement containing electronics and for terminating the potentially destructive state. In the method and system currents consumed by the electronics through connecting mechanisms from at least one supply voltage are measured. The measured currents are compared with respective stored maximum permissible currents stored in a memory. Further, the connecting mechanisms are disconnected from the at least one supply voltage to ...

A differential amplifier, of such as a comparator or operational amplifier, has two base input terminals. The base-emitter junctions in the two input transistors are protected by corresponding protective transistors connected as diodes, i.e., the emitter and base of each protective diode are connected. The effective pn-junction in the protective transistors is the junction between the base and collector which normally has a larger breakthrough voltage than the pn-junction between the base and em...

The helmet comprises a crown (1) with belts (2) which are blocked from moving with respect to the crown by means of buckles (3). The belts are wound on the buckles. The buckles are inserted in slits (6) formed on the crown (1) along its entire thickness. Recesses (7) are formed on the external surface of the crown. The buckles (3) fit into the recesses so that the external surface of the buckles is essentially on the level of the external surface of the crown (1).

A secure container comprises an external wall including a door (56) and a lock (36) for securing the door (56). The lock (36) comprises a lock mechanism (47) located internally of the wall (56) and a plate (40) mounted between the wall (56) and the lock mechanism (47). The plate (40) is tiltable in response to applied pressure.
