Title: Compressed air sensor - controls level of cannula removing measured amt. of liq. from container
Inventor: KRUEGER BERND
IPC: G01N1/00
Filed: 1980-10-18
Abstract: A measured amt. of liq., esp. a clinical specimen, is taken from a container and transferred by a piston communicating with a vertically mobile cannula whose end dips into the liq. to a depth controlled by a level sensor. This operates with compressed air delivered down the outer of a double tube concentrically surrounding and shorter than the cannula. Air after travelling down this space is reflected from the liq. surface back up the inner space where its pressure is sensed and actuates a drive to move the cannula vertically. The outer tube is pref. longer than the inner tube, and their ends are shaped to facilitate air movement from the outer to the inner space. Level detection involves no physical contact between sensing means and liq., and the cannula need only dip about 1 mm below the surface. The device is compact, e.g. the unit entering the container may be 3 mm dia. including the 1 mm dia. cannula.

Title: Charger for battery-operated electrical appliances
Inventor: HENSEL WILHELM
IPC: H02J7/02
Filed: 1981-01-08
Abstract: In order to shorten the non-availability times in operation of an electrical appliance having a rechargeable battery, the charger according to the invention is constructed with a rapid-charging appliance with automatic disconnection and with signal transmitters which are controlled by the electronics and periodically transmit interrupted signals at a low frequency when the voltage oscillates between the final charging voltage and the rated voltage after charging has been completed. The low signal frequency indicates that the electrical appliance is ready. As a battery ages by losing its forming capability, the signal frequency becomes higher and higher which gives an early indication that the battery must be replaced. Figures 1 and 2 show a charger having a charging housing (1), which is constructed as a charging stand, for accommodating a soldering iron (2) in the charging and readiness position. According to Figures 5 and 8, the charger can also be arranged in a plug housing (26, 27), the electronics (which are not shown) being located in the space (32). A connection to the electrical appliance passes through the opening (34). Visual signal transmitters are designated by 10 and 39 and acoustic signal transmitters by 11 and 38 in the figures. <IMAGE>

Title: Brake pressure regulator for a pressure medium operated vehicle dual circuit brake system
Inventor: SCHOPPER BERND ING GRAD
IPC: B60T8/26
Filed: 1981-11-26
Abstract: The brake pressure regulator according to Fig.1 has a control piston (24) arranged between inlet (5) and outlet (6) of a first brake circuit (I) with a closing element (25) of a valve (10) for influencing the pressure build-up of the first brake circuit (I); it also has a sensor plunger (30), which can be acted upon on the one hand by the master cylinder pressure of the second brake circuit (II) and on the other by the pressure in the outlet (6). The sensor plunger (30) has a stop (23), by means of which it opens the valve by way of a stop (27) of the control piston (24) in the event of movement in the opening direction of the valve (10) owing to a failure of the brake circuit (II); during the pressure build-up prior to closing of the valve (10) it bears against a shoulder (17) fixed to the housing and limiting its movement in the closing direction. The sensor plunger (30) is thereby supported on the shoulder (17) even before the start of the control process and thereby effectively isolated from the control piston (24). As a result undistorted control is possible. <IMAGE>

Title: Device for compensating axial misalignments between a driving pinion and a mating gear meshing with it
Inventor: HECKING LUDGER
IPC: F16H57/022
Filed: 1982-03-13
Abstract: The device serves for the automatic compensation of axial misalignments in the case of intermeshing gearwheels (1, 2). There are cases in which continuously satisfactory alignment of the gearwheel discs is not possible since external influences can result in a continuous change in the position and direction of one axle. In order nevertheless to obtain satisfactory tooth engagement, the driving pinion (1) must be able to follow changes in alignment. The pinion is therefore fixed to the pinion housing (4, 5, 6) by means of lamellae (7) allowing axial misalignments to be compensated by elastic deformation of the lamellae. However, the lamellae are connected on the other side to a bearing journal (8), the axis of rotation of which extends perpendicularly to the plane of the lamellae with the result that deviation errors can also be compensated by swivelling of the pinion housing about the axis of the bearing journal. <IMAGE>
