Patent SE-8304392-L (SE)
Inventor: REMMERS G M
IPC: H02J7/14
Filed: 1983-08-12
Abstract: A battery to be charged is connected to the stator winding output terminals of a permanent magnet alternator by way of two half-wave rectifier circuits. Each rectifier circuit has at least one controlled rectifier in series with the battery. The controlled rectifiers have gate terminals, respectively, for supplying a signal that renders them conductive. A semiconductor isolating or shut off switch, preferably a transistor switch, connects the battery terminal to a voltage divider circuit that develops two discrete voltage levels that are proportional to battery voltage. A zener diode circuit fed from the battery provides a stable reference voltage. A first comparator compares one of the voltages that corresponds with the battery voltage being a predetermined amount below full-charge condition with the zener reference voltage and if the reference voltage is exceeded, the comparator trips to turn on one of the SCR diode rectifiers for charging the battery at a relatively low rate with half-wave rectified dc. A second comparator compares a still lower voltage in the divider with the zener reference voltage and trips to effect turning on the other SCR diode to charge the battery additionally to the other SCR and the half-wave rectifier circuit in which it is connected. Thus, full wave charging occurs. If the battery is accidentally disconnected high voltage could develop on the alternator terminals. Disconnection turns off the isolating transistor and the controlled rectifiers lose their gating signals and turn off. High voltage across the alternator during the last half of the cycle before turn off is dissipated to ground by a zener diode.

A percussive screwdriver (8) with an impact boss (9) is arranged in a manner which allows it to be rotated jointly with the flyweight and displaced axially relative to the latter. There is a spindle (5) with an impact boss (6) which is mounted coaxially with the drive shaft in the casing and has a portion (7) for pushing on a screwing head. An intermediate shaft (14) with a flange (16) has at least one cam surface (20) and is connected to the spindle so as to rotate jointly with it. At least one rolling element (22) is arranged between the front faces (17) of the flange and of the impact element for periodic interaction with the cam surface of the flange.

Abstract: The gas-return valve 7 comprises a valve with a valve-head and a valve-stem. A spring-loaded diaphragm 9 is fixed to said valve stem, and on one face of the diaphragm there acts, in suction chamber 11, a suction derived through a transfer duct 13 from a pneumatic controller 14. The pneumatic controller 14 has two chambers 23, 24 separated by a diaphragm 19, the first chamber 24 of which communicating, firstly and permanently, with the transfer duct 13 and, secondly and alternatively in dependence upon, and as governed by, differences in instantaneous pressure, either, with the induction pipe 2 at a location upstream of the throttle valve 3, or, with atmosphere; the second chamber 23 being in permanent communication with a location on the downstream side of the throttle valve 3. In this way the pressures transmitted to the valve 7 through the transfer duct 13 from the pneumatic controller 14 are governed by differences in instantaneous pressures at locations on the upstream and downstream sides, respectively, of the throttle valve 3 in the engine induction passage. <IMAGE>

Abstract: The invention relates to a device 1 for automatic feed- out of plasters which are arranged parallel with one another on a strip, the strip being enclosed in a pack. The apparatus comprises a chamber 2 for the pack and motor-powered drive members 7,8 by means of which the plaster strip is advanced. The plaster strip is segmented in the pack, one plaster being released from the strip at the segmentation point and being fed forward to a delivery area upon the continued advancement of the strip. At the delivery area there is a detection device 12, which detects whether a plaster is present in this area. The detection device, which is here constituted by a reflection photo element working on infrared light, controls the supply of energy to the drive motor so that the motor is deactivated when the detection device detects the presence of a plaster on the delivery area, whereas the motor is activated when there is no plaster present. <IMAGE>

Abstract: Arrangement of machinery for the discharging and cleaning of material which appears as fragments and pieces ranging in size from large blocks down to dust particles, which are to be removed and carried away from a surface. The arrangement 1 comprises a working unit 4 and a support unit 3 to drive the working unit over the surface, during which operation it takes up the material and delivers it to an area set aside for such material which has been removed from the surface. The working unit 4 takes the form of a box 12 with a first section 20 and a second section 21. The first section can be displaced relative to the second section, which is supported by the support unit 3, between a first position in which one of its edges makes contact with a corresponding edge of the second section, so that the box is in effect closed, and a second position in which its edge is moved away from the edge of the second section so that the box is open. At a distance from the box's aforementioned edges, the working unit 4 is fitted with a brush appliance 30 which connects with an opening in the box, and is designed to collect particles from the surface and deliver them into the box. In this way the working unit can operate partly as a grab for taking up the larger pieces, and partly as a brush. <IMAGE>

Abstract: The invention relates to a wind machine 1 which makes it possible to utilize gusty wind to create mechanical motion, which motion can be used in order to drive a mechanical arrangement in the form of, for example, a liquid pump 10 or the like. The wind machine 1 comprises a bearing member 4 in order to make possible rotation motion relative to the driven arrangement 10, and a member 2 which gathers wind energy and, via an essentially horizontal shaft 7, is pivotably arranged relative to said bearing member 4. The member 2 gathering the wind energy is, at least in its position unaffected by the wind, located at a distance from the axis of rotation 12 of the bearing member 4. The member gathering the wind energy consists of a plate element 2 which bears at its upper edge a lever 3 which, via the essentially horizontal shaft 7, is pivotably mounted relative to an arm 5 of the bearing member 4. The axis of rotation of the bearing member 4 is oriented essentially vertically. That end of the lever 3 facing away from the plate element 2 has an attachment for a member, for example a pump rod 15, from the driven arrangement 10. If necessary, the plate element 2 has at its lower end one or more counterweights 20. The wind machine 1 adjusts itself automatically in the desired manner in relation to the wind direction and a gust of wind pivots the plate element 2 according to the arrow B, after which, when the gust of wind stops, the plate element 2 returns to its starting position as a result of its own weight. The motion of the plate element 2 results in the pump rod 15, for example, being subjected to a reciprocating movement so that the pump 10, for example, is imparted its drive. <IMAGE>
