Filed: 1969-09-30
Abstract: A hf oscillator with two degrees of freedom is provided with high operational stability by using two coupled resonator circuits. The circuits may be individually tuned to provide optimum performance. A transistor (Tr) with emitter coupled feedback (CE) has a frequency timing circuit provided by an inductance (L1), capacitor (C4), capacitors (C2, C3) and decoupling inductance (L2).

Abstract: Disclosed is a circuit for generating in a pulse motor drive coil an initial pulse motor drive pulse in a unit length of time during which a second hand is driven by one step, after resetting for time correction has been released. The output of a divider chain for frequency-dividing a standard frequency signal from a quartz oscillator into a signal having a period equal to the unit length of time is delayed by a delay circuit, and by a logic gate responsive to the output of the delay circuit and the output of the divider chain there is produced an output pulse signal having a period equal to the unit length of time and a narrower width. The output of the logic gate is supplied to a binary counter. An output circuitry responsive to the output of the binary counter and the output of the logic gate generates drive pulses in the drive coil. The reset signal is applied to the delay circuit and at least a frequency divider stage producing the signal the period of which equals the unit length of time.

Abstract: The clamping element comprises a rapid-adjustment device combined with a power amplifier. The power amplifier is enclosed by a rotatable adjusting sleeve (2) which engages, with an external thread (3), into an internal thread (4) of a housing (1) surrounding it. A first clamping member (5) is fixed in the adjusting sleeve (2) and a second clamping member (11) is rotatably arranged in the adjusting sleeve (2). Arranged between both clamping members (5, 11) are two clamping bolts (13). The clamping bolts (13) are supported on the second clamping member (11) at as small a distance (a) as possible from the adjusting-sleeve axis (A). An actuating and pull rod (10), connected to the second clamping member so as to be fixed in terms of rotation and tension is guided either through a central recess in the first clamping member or through two diametrically opposite, lateral recesses (9) in the first clamping member (5). The last-mentioned recesses (9) are of such size in the circumferential direction of the adjusting sleeve (2) that they permit a limited twist, sufficient for rotating the second clamping member (5) with respect to the first clamping member (11), of the actuating and pull rod (10) with respect to the adjusting sleeve (2). On rotation of the actuating and pull rod (10) in the clamping direction, the latter is first drawn axially into the housing by rotation of the adjusting sleeve.

Abstract: 2. It is intended to develop an easily assembled system consisting of double-walled pipe elements which can be produced individually at the works and whose ends are precisely circular and which can thus be welded together to form a pipeline system, without using any special clamping device. This object is achieved by means of double-walled pipe elements which are characterised in that   a) a centring ring is fitted on each of the two ends between the inner pipe and the outer pipe; b) a connecting ring is welded to each of the two ends, which ring connects the inner and outer pipe rigidly to one another and c) if necessary spacer rings are fitted as spacers to the inner pipe.   Such double-walled pipe elements are suitable for the assembly of pipeline systems in which corrosive fluids are conveyed.

Abstract: PROBLEM TO BE SOLVED: To arithmetically calculate the vehicle center-of-gravity height at high speed and in real time by using a specified arithmetic expression simplified by use of the outputs of a vehicle longitudinal acceleration sensor and a plurality of pressure sensors of air suspensions as input information. SOLUTION: The mass acting on a vehicle in braking corresponds to the value M-J of subtracting an unsprung mass J from the total mass M, and the (M-J)×G of multiplying this value by an acceleration G corresponds to the vehicle advancing directional load in braking. Accordingly, the moment M01=(M-J)×G×H of multiplying this load by a vehicle center-of-gravity height H acts on the vehicle in the advancing direction. On the other hand, when the horizontal distance from each center of the front axle and the rear axle to the vehicle center-of-gravity position is Lf, Lr, and the load change quantity generated in the rear axle in braking is ΔWr, and the moment added to the vehicle is M02=ΔWr×Lf+ΔWr×Lr-ΔWr(Lf+Lr). Further, since a wheel base is L=Lf+Lr, M02= ΔWr×L.  Since M01=M02, (M-J)×G×H=ΔWr×L, and the vehicle center-of-gravity height H=(ΔWr×L)/(M-J)×G. A correction coefficient (k) is provided thereon to provide H=(ΔWr×L)/(M-J)×G. Although the correction coefficient (k) is principally 1, an experimentarily proper value can be practically provided according to the kind of vehicles.
