Abstract: An arrangement for operating hydraulic actuators (1) in a rock drilling machine, comprising pressure-controlled over- center valves (7, 8) connected to conduits (5, 6) leading to chambers (3, 4) positioned on opposite sides of a piston (2) or the like of the double-acting actuator, and non-return valves (11, 12) connected in parallel therewith. In order to operate the actuator (1), one or two cartridge-type regulating valves (14, 15) are mounted with the actuator for remote control by way of signal lines (22, 23) for, preferably, electrical signals. In the arrangement, a single pressure fluid supply hose (13) and a single pressure fluid return hose (9) are required for the operation of all the actuators (1) each of which has an associated control circuit as shown. In operation remote actuation of say valve (14) directs fluid from hose (13) through non-return valve (16) into the left hand working chamber of the actuator (1). Pressurisation of a control conduit (19) also occurs, resulting in opening of the valve (8) and flow of fluid from the right hand working chamber (4) to the return hose (9). Overload conditions in chambers (3, 4) are relieved through the valves (7, 8).   <IMAGE>

IPC: A01N63/50
Filed: 1990-05-22
Abstract: Treatment on and in seeds, plants, fungi and fungal spores comprises using aq. soln. of nuclease(s). The nucleases specifically used are (i) RNases (Ribonucleases); (ii) DNases (Deoxyribonucleases), e.g. DNase I, in partic. pancreatic DNase I, and II; and/or (iii) Endonucleases I and/or II. Also claimed is the method whereby aq. nuclease soln. of 0.50-2500, ppm that may contain agar is applied to the plant material by dipping, spraying or pouring. More specifically, the pref. aq. nuclease soln. is injected into the xylem and/or phloem of an infested tree. Several nucleases can be used at the same time or in intervals and the nuclease solns. are pref. at below 20 deg.C.. USE - Used against phytopathogenic viruses. In an example at a temp. below 20 degree C, 2 1 water contg. RNase A (125ppm.), DNase I (125ppm.) and 2% agar was sprayed onto 25 g of tobacco seeds with tobacco mosaic virus (TMV) attached to them.

Title: Broken glass sorting device - has open edge along one side of sliding surface for ejected glass to drop off into separate piles
Inventor: SEICHTER WOLFGANG DIPL ING
IPC: B07C5/36
Filed: 1990-05-28
Abstract: The appts. to sort broken glass fragments (4), with a downwards sliding surface and a limit wall along one side where the fragments slide separately along the wall, has an open edge (39) at the sliding surface (2) opposite the limit wall, to allow glass fragments (4) to be moved from the sliding surface (2) over the open edge (39). The glass fragments (4) are directed to the open edge (39) of the sliding surface (2) for ejection by one or more impellers (18-21). The ejected glass fragments (4) are caught by one or more collection surfaces (35) where a pile (36) can be formed on the surfaces, which are large enough to carry a pile (36). The surfaces (35) are positioned so that the glass fragments (4) ejected over the open edge (39) land on a pile (36) of fragments. Air jets are pref. as the impellers (18-21) which can deliver an air stream at a passing glass fragment (4) for a short duration, such as 0.1 sec., to shift the fragment across its line of travel on the sliding surface (2) to drop over the open edge (39). Drop shafts are at each impeller zone, to collect the ejected glass fragments. The colour of the glass fragments (4) can be detected by sensors, to remove them from the sliding surface (2) selectively, to give separate collected piles according to colour or other criteria. ADVANTAGE - The mechanism to change the direction of glass fragment travel is simple to give an effective sorting action on the broken glass. The low collision rate between glass fragments during movement reduces the wear on the appts.

Title: Current measuring arrangement for synchronously clocked power converter - safeguards transformer prim. current proportional voltage by Zener diode shorting switch closed in synchronism with clock
Inventor: JEGGLE NORBERT DIPL ING
IPC: H02M3/158
Filed: 1990-10-20
Abstract: When positive current (I) flows through the prim. winding of the transformer, a current (IB) induced in the sec. winding flows through a diode (D2) and load resistance (RB) which develops a proportional voltage. Energy stored in the sec. winding is dissipated as heat by current through another diode (D1) and a Zener with a short-circuiting switch (S3). This practically eliminates the magnetising effect of negative prim. current so that the proportional control voltage is unimpaired. The switch may be a MOSFET. ADVANTAGE - Measurements are safeguarded against negative currents which could cause transformer saturation and overload or destruction of electronic components.
