Abstract: 1,262,249. Transistor blocking oscillators and waveform generators. ROBERT BOSCH G.m.b.H. 3 Sept., 1970 [4 Sept., 1969], No. 42107/70. Heading H3T. [Also in Division G1] In an I.C. engine fuel injection control system the relaxation period of a monostable multivibrator 12, which determines injection duration, is determined by the intake manifold pressure, via transformer 15, and in dependence upon engine speed by a control voltage, Fig. 2, which is triggered at the end of each injection pulse produced by the multivibrator 12.  As shown, at the end of each injection pulse, i.e. t = 0 in Fig. 2, a capacitor C 4 , which provides the voltage Us applied to point H of multivibrator 12, is discharged, and is then successively charged at instants t 1 , t 2  and t 3  via respective charging sources R 8 , D 2 ; T 3 , R 11  R 13 , D 4 ; and T 4 , R 16 , R 18 , D 7 . The value of the voltage Us attained by C 4  at the end of the next injection pulse (which cause C 4  to be discharged at t=t 4 ) then determines the duration of the succeeding injection pulse. Thus as the engine speeds up, the frequency of injection pulses increases and so the value attained by the voltage on C 4  at the end of each injection pulse varies along the curve of Fig. 2 and so varies injection duration.  In a modification, Fig. 3 (not shown), a second storage capacitor C 5  is provided in parallel with the capacitor C 4  in such a manner that the control voltage Us, Fig. 4 (not shown), is determined by the capacitor having the more positive voltage at any instant. In an alternative embodiment, Fig. 5 (not shown), a single storage capacitor C 6 , after being discharged at the end of each injection pulse, is charged by a first charging source, discharged, and then charged once or a successive number of times by a second or a successive number of different charging sources, to provide a control voltage Us, Fig. 6 (not shown), which increases and decreases.

A cellulose-containing component for bonding with one of more like cellulose-containing com-- ponents to produce an air and water vapour permeable cellulose-containing material comprises a component, e.g. wood chip or veneer, which has been impregnated only in. the cell membranes of at least some of the cells with a low molecular weight, water soluble, settable impregnating resin which has been set, and saturated at least at its outer surface with a second impregnating resin. This second impregnating 'resin ,is used in the bonding of the cellulose-containing components to form the finished material and may be the same as the first impregnating resin. In the first impregnating step the cell membranes may be impregnated with 5-10% by weight impregnating resin. The resins preferably employed are based on mono-nuclear phenol-alcohols, e.g'. dimethylol phenols or trimethylol phenols and are preferably neutral adjusted resins. The second impregnating resin may be reinforced by the addition of 3-5% by weight resorcinol. The component may be impregnated in the first impregnation either in the dry Or moist state, preferably by the immersion method involving a diffusion storage step. The setting may be carried out by "condensation" drying in conventional drying plants. The impregnation with the second impregnating resin can be carriad out immediately after drying the wood by lightly moistening of the surface with for example 40-60% solids content of the impregnation resin solution'.

Voltages representing m A , BW A  are multiplied together at 53 to yield a voltage representing M A , the specific moisture content (moisture weight per unit area) at "A" which is added at 57 to a voltage representing BWc from which sum is subtracted a voltage representing BW A  to yield a voltage representing M C  (=BW C  - BW A  + M A ). ). A differential amplifier senses M c  and energizes a motor to drive the wiper of a solution potentiometer which is ganged to the pen of a chart recorder. The multiplier 53 may consist of two potentiometers in cascade, Fig.2 (not shown) or of a self-balancing wheatstone bridge, Fig.3 (not shown), a summing network being used in both embodiments as the adder 57. Since M A  is directly proportional to m A  for small changes and where the basis weight is constant, a multiplier stage may not be required. In such an embodiment, Fig. 4, a voltage representative of M A  is set at the wiper contact 401 of the potentiometer 402 for an appropriate value of percentage moisture content m A  as displayed on the gauge 49 to which the wiper is ganged, the basis weight being known. The required moisture content Mc is then measured by summation as before. To extend the range of accuracy of this method calibrating resistors and switches 430-3 and 440-3 are included, or the law of the potentiometer 402 may be non-linear e.g. exponential. The calibrating switches are ganged with a range switch 450 which switches calibrating resistors in the dry end basis weight gauge.
