Abstract: The chassis for a toy vehicle has a pair of drive wheels, which can be rotated by an electric motor via a reducing gear, and a pair of support wheels which receive a source of power, e.g. a battery, which can be connected to the electric motor by a switch, and serve as supports of a bodywork. In order to reduce the electrical outlay and to simplify the mechanical outlay for the connection of the chassis and the bodywork, a chassis box (1) is provided, which is open at the top, can be closed by a detachably fixed plug-on lid (42) and accommodates a receiving box (27) for the source of power (36) in a transversely displaceable manner, which receiving box contacts contact rails (18, 21, 22), which are in connection with the electric motor (14), with outside power source contacts (38, 39) as pole-changing switches from a central separating position to revolutions of the electric motor (14) in the one or other direction of rotation.

Abstract: The invention relates to a tamper-evident seal assembly for use with a locking mechanism, the locking mechanism including a sliding member 5 which is slidable between a locked position and an unlocked position, said sliding member having a transversely projecting peg portion 11. The seal assembly comprises a channel portion 20 defining in its base a longitudinally aligned slot 21 through which the peg portion 11 can protrude, and a disposable breakable seal member 22 which is longitudinally slidable in the channel portion. The seal member 22 has means 23 for engagement with the projecting peg portion 11, such that, in the unlocked position, the seal member can be placed in the channel portion and in engagement with the peg portion, the seal member then being slidable in the channel portion and engagement between the seal member and the peg portion causing corresponding sliding of the sliding member to its locked position. In this position retaining parts 24 of the channel portion prevent lifting of the seal member, whilst the engagement between the seal member and the peg portion prevents sliding withdrawal of the seal member, whereby the locking mechanism is held in the locked position until the seal member is broken.

Abstract: The doctor device has a profile member pivotally mounted to a retaining member that is carried on a mount. Vertical movement of the mount causes angular displacement of the profile member thereby changing the material applicaton area disposed adjacent and upstream of the doctor. The doctor is either a doctor blade or roll doctor. In the case of a roll doctor, a receptacle is formed in the profile member and the roll doctor is magnetically retained with the receptacle. During application of a material to an application surface with the roll doctor, the roll doctor is magnetically attracted to the application surface by a second magnetic device located beneath the application surface or work surface.

Abstract: An earth working apparatus has a helical coil (12) rotatable about a horizontal axis by moving the coil over the ground. Cleaning means for cleaning earth from the coil has protruding portions which protrude into the spaces between consecutive turns of the helical coil (12), and which are moveable in a longitudinal direction along the coil to allow for the effective movement of the spaces of the coil along the longitudinal direction during rotation of the helical coil. The cleaning means is a further, smaller diameter, helical cleaning coil (19) which hangs from a central core (15) of the earth working coil (12), and effects cleaning of the coil (12) by protruding into the spaces between the turns of the earth working coil (12). <IMAGE>

IPC: H02J9/06

Abstract: A UPS system includes a mechanical backup input line isolation switch (104) to provide mechanical isolation between a primary energy source connected to the input line (101,102) and a secondary energy source (120) upon detection of a failure of an electronic isolation switch (107) normally providing isolation between the input line and the secondary energy source. Detection of such a failure is accomplished by means of a dummy load (150) which is connected across the input line. Its impedance is sized to permit a small low level of current flow, above normal leakage current levels permitted by a functioning semiconductor electronic line switch, if energy is reverse coupled from the reserve energy source via the failed electronic line switch, without draining significant power from the primary energy source when the UPS is normally operative and deriving power from the primary energy source. A power flow direction sensing circuit (151) detects the direction of power flow at the input to which the primary energy source is connected to the UPS, and a control circuit (152) responsive to the power flow direction sensing circuit disconnects the input from the primary energy source, if reverse power flow is detected, by activating the mechanical switch.

Abstract: The device consists of a solar sail (30, 31) which is asymmetrical about an axis (Z) and which subjects the probe (S) to a torque from solar pressure which turns it over. A momentum wheel (20) rotates about a perpendicular axis (X). Because of this, the probe rotates about the axis (Y) perpendicular to the two previous axes. The speed of rotation of the wheel (20) is varied by a control system (23, 24) in order to alter the speed of rotation of the probe.

Abstract: In the process of fixing a metal screen in the housing of a vacuum switch, the screen is plastically deformed radially outwards over an internal supporting edge in the housing. The plastic deformation of the screen is carried out at an edge thereof, in such a way that an outward flanged edge is formed. Thus, the screen is retained on the supporting edge by that flanged edge and a part of the housing with a relatively large diameter. Therefore, the screen has a part with a relatively small diameter which is essentially equal to the internal diameter of the supporting edge of the housing.
