Title: Electrostatic-vacuum record cleaning appts. - uses air blower adjacent to charging device to aid dislodgement of dust particles
Inventor: DUNN ROBERT EDWARD
IPC: G11B3/58
Filed: 1980-01-14
Abstract: Appts. uses a turntable on which the record is supported and rotated beneath a charging mechanism that imparts an electrostatic charge, causing dust particles on the playing surface to be loosened. A vacuum device, supported above the playing surface adjacent the charging device, causes the loosened particles to be removed and carried away by air movement. To aid in dislodging the dust particles, it is advantageous to employ an air blower located adjacent the charging device. An attraction member, charged oppositely to the particles, can pull the particles away from the record and toward the vacuum. An additional conductor to which an alternating current is applied can be employed to remove any residual charge from the record, thereby preventing additional dust particles from being attracted to the record.

Title: Laminar burner for spectrometric applications - has mixing chamber smoothing out sample liq. fluctuations and reducing cooling
Inventor: TOMOFF TOMA DIPL ING
IPC: G01N21/72
Filed: 1980-03-18
Abstract: A laminar burner for spectrometric applications has a mixing chamber in which a liq. sample is atomised and mixed with oxidant and combustion gas before being delivered as an aerosol to a burner head. The adjustment of the combustion gas-oxidant mixture is simplified and the chamber cooling as a result of the atomisation reduced compared to conventional arrangements. This ensures that a larger proportion of the sample fluid is delivered in atomised form to the flame. A mechanical atomiser is used. The sample liq. is sucked up by a pump, brought under pressure and atomised via a valve nozzle. The mixing chamber also performs a smoothing function on the pulsations occurring in the sample liq. Condensation is reduced compared with conventional burners.

Title: Electrically driven hand tool e.g. chain saw - has two handles with associated switches in series for safe operation and self-braking action
Inventor: SCHULZ MANFRED DIPL ING
IPC: F16P3/20
Filed: 1980-06-19
Abstract: The electrically driven hedge trimmer has a main hand grip (13) and a secondary grip (11) both having a pressure-activated switch. The switch (4) in the main handle (13) has a trigger (18) for closing it, and the second switch (5), which is contained in the motor housing, is closed by a lever action when the trimmer is gripped by the operator. To supply current to the drive motor (12), both switches (4,5) have to be closed, necessitating the operator holding and gripping both handles of the trimmer at the same time. An internal relay is connected via the switches so that in the 'off' position, the motor field winding and armature are in parallel. This gives a braking effect as the motor runs down, due to the generator configuration. When both switches are closed, the relay connects the armature and field in series and the motor runs normally. It is not possible to use the hedge trimmer without gripping both handles, thus avoiding accidents to fingers or hands.
