Patent FI-924919-A (FI)
Inventor: VON BERGEN ERNST-PETER
IPC: F16J15/32
Filed: 1992-10-29
Abstract: The invention employs the principle of the prior art for cooling a heated body by means of so-called heat pipes, with seal devices for rotating shafts, in particular for a ship's propeller shaft. According to this principle, an externally closed chamber extending in the longitudinal direction and filled with a liquid working fluid extends on one end into the body to be cooled, and on the other end into a cold medium, whereby a constant circulation takes place, so that the work fluid is evaporated in the hot portion of the chamber, the vapor flows into the cold portion of the chamber, condenses there, and the condensate is returned to the hot portion by way of a capillary structure (FIG. 1 ).

Date Jul. 21, 1994Tuning a combiner filter, which includes two separate tuning modes: coarse adjustment applied when the combiner is taken into use by utilizing a measuring branch for forward power and a coarse measuring branch for reflected power; and fine adjustment applied in continuous operation by utilizing the measuring branch for forward power and a fine measuring branch for reflected power. The two-stage adjustment decreases the mutual interference of the filters during tuning. The correct tuning frequency of the combiner filter is obtained as the average point of the reversing points obtained in the adjustment process, the filter being driven to the average position. This so-called positional average tuning has two advantages: the effect of noise present in the power measuring line is reduced, and the tuning error caused by the termination of the dynamics of the A/D converter positioned after the detector at low power levels and good combiner filter settings is diminished. Power measurements are made frequency-selective by mixing.

Abstract: A circular saw with a saw blade (12) angularly adjustable in a rotatable supporting table (13) is to be equipped with a tilting suspension which works trouble-free and does not displace, as a function of the tilting, the chord (15) of the saw-blade working section (14) projecting through the supporting surface (16). For this purpose, a triangular link (21) hangs with its base angles on pendulum bars (24, 25) at a distance below the supporting surface (16). In the vertex angle (34) of the triangular link (21), a stay (30) rigidly connected to the bearing (19) of the saw blade is suspended in an articulated manner. The stay (30) at the same time serves as a parallel bar of a parallelogram guide (35), the longitudinal bar (36) of which is the rigid extension of one (24) of the two pendulum bars (24, 25). The connecting leg (32) from the end of this pendulum bar to the vertex angle (34) of the triangular link (21) is at the same time one of the two transverse bars of the parallelogram guide (35). The latter, during lateral displacement (under pendulum-induced lifting) of the triangular link (21), causes pivoting of the saw blade (12) about the vertex angle (34) and thus tilting of the working section (14) about the chord (15) immovable in the supporting surface (16). <IMAGE>

Date Feb. 22, 1996A bow saw provided with a handle on the rear end of its bow-shaped frame can be coupled to a rod (32), for instance a telescopic rod, by a rod-attachment coupling. For this purpose, the rear section of the bow-shaped frame (10) has a detent element (34) which is welded on it which is surrounded by the handle shell (30) of the handle and a device insertion pin (36) which is swingably fastened on the frame (10) by fork arms (38) in the region of the detent element (34). This device insertion pin (36) can be form-locked to the detent element (34) in the outward-swung position of the handle so that the device insertion pin (36) protrudes towards the rear and a rod (32) provided with a corresponding insertion hole and a coupling can be pushed onto it. The movement of the device insertion pin (36) into the coupling position is effected by entrainment upon the swinging of the handle shell (30). When the rod is attached via the rod fastening coupling to the bow saw, even distant branches or the like can be cut, but in the uncoupled condition the coupling device does not prevent actuation of the saw when the handle shell is in its inward-swung position.

Filed: 1965-01-08
Abstract: 1,098,022. Echo-sounding. ELECTROACOUSTIC, G.m.b.H. Jan. 8, 1965 [Jan. 10, 1964], No. 1046/65. Heading H4D. In an arrangement for distinguishing between the sea-bed echo and close-lying fish-echoes in an echo-sounder employing an electro-chemical recorder, an electronic circuit is connected in shunt with the resistance of the electricallysensitive recording paper to reduce the recording voltage for the strong sea-bed echo to a value below that of the recording voltage for the weak fish-echo. In the embodiment of Fig. 6, amplified echo signals U3 are rectified in a network N1 to provide bias for a valve R÷2 giving an output voltage U2 which is applied to the stylus 3 of the recorder (Fig. 1, not shown). The shunt path for the recording voltage U2 comprises the anode-cathode circuit of a valve RÍ1 which is rendered conducting when the amplified echo signals, fed through a rectifyng network N3 to its grid, exceed a predetermined threshold level. For normal operation the threshold level is arranged to be above the maximum expected fish-echo level. The degree of shunting of the recording voltage U2 is determined by an anode resistor W2 which is set such that fish-echoes record as black on the electrically-sensitive paper, whereas sea-bed echoes record as light grey or white. In a second embodiment (Fig. 7), the shunt path comprises the anode-cathode circuits of valves (RÍ3, RÍ4, RÍ5) in parallel and different threshold levels for the valves may be set by a potentiometer network (W3, W4, W5) and an external gridbias voltage source (U4). In a third embodiment (Fig. 8), the anode resistor W2 is replaced by a valve (RÍ6) whose dynamic resistance is varied by applying a control voltage to its grid, the control voltage being derived from an external source or, in order to achieve an echoamplitude compression to match the tonal range of the recording paper, from the echo signals U3. In the embodiment of Fig. 9, the recording voltage U2 is fed to an electrochemical recorder (A1) and also to a C.R.O. display, the recorder (A1) and C.R.O. display being provided with separate shunt paths, such as valves (RÍ7 and RÍ8), which may have different threshold levels and different shunt values. The embodiments disclosed may be used as an add-on unit for known echo -sounders -

[Class 100 (ii).] In a paper-folding machine of the buckling type a guide-member is provided which is retracted to allow a folded sheet to enter a buckling-plate and is advanced to guide the buckled sheet to the folding-rollers and also to prevent the edge of the folded portion of the sheet fouling the rollers. As applied to a machine for folding successively margins on the two ends of the sheet and then parallel folding along the centre line of the sheet, the sheet after entering the second fold-plate h is engaged by a guide q which prevents the folded margin formed by the first fold-plate e from rising and fouling the roller g as it leaves the plate h. The last fold-plate m imparts a central fold a<3> to the sheet. As soon as the fold a<3> is gripped by the rollers k, o, a guide-member r is slid forward so as to prevent the folded margins from rising and to ensure the proper formation of the fold. The guides q, r are carried by transverse rods s, t slidable along cams w, x into and out of position and are operated by connecting-rods 2, 3 from adjustable cams on a driving shaft. A drop-roller operated from the same shaft feeds the sheets in timed relation to the operation of the guides.
