Title: Improvements in Methods of and Apparatus for the Electrodialytic Preservation of Timber
Inventor: MARRIOTT CHARLES LESLIE
IPC: B27K3/02
Filed: 1967-12-05
Abstract: 1,161,260. Preserving timber by electrolytic impregnation. C. L. MARRIOTT, C. H. MARRIOTT and H. P. MacPHERSON. 5 Dec., 1967, No. 55348/67. Heading A5E. [Also in Division C7] Timber is preserved by introducing preservative or fungicidal material into fresh timber by inserting one end into a vessel containing a solution in dilute sulphuric acid of the preservative or fungicidal material so as to contact an electrode in contact with the solution, applying a second electrode to the other end of the timber, and passing D.C. through it, whereby ions of the preserving material are introduced into the sap of the timber. The preserving material may comprise copper sulphate or arsenic pentoxide. Typically a felled tree trunk is placed vertically on an electrode submerged in a trough containing the treating solution and a second electrode is placed on the top end. By periodically reversing the applied polarity both anions and cations may be introduced into the sap. Alternatively the tree may be placed horizontally on skids or rails and a hemispherical treating solution container, itself serving as an electrode, may be clamped to each end. In a further arrangement sawn timber is immersed between top and bottom electrode in a vat containing treating solution. In all cases a high voltage is applied initially but as the conductivity of the tree sap increases the applied voltage is reduced. The applied voltage may be in the range of 1 to 1000 volts and the current may be in the range 0.001 to 100 amps.

Title: A device for transmission of information at varying frequency
IPC: H04B1/66
Filed: 1970-12-18
Abstract: 1287375 Radio communication system PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Dec 1970 [23 Dec 1969] 60252/70 Heading H4L In a secret communication system of type wherein the frequency of transmitted carrier is changed in steps according to a repeated pattern and the received signal is heterodyned down to a constant frequency IF signal by mixing with a similarly frequency changing local signal, ground reflections &c. of the signal cause the phase of the IF signal to vary with the frequency. To overcome this, the If phase for each of the n frequency steps is detected and stored in a respective position is a memory having n positions, one for each frequency step. The next time a particular frequency step is reached, the IF signal is phase corrected by means of a variable delay under the control of the output of the position of the memory containing the phase information of the same preceding frequency step. The transmission system, Fig. 1, comprises a 10 Mc/s. oscillator 1, having antiphase outputs selected by switch 2 and key 12 to give phase modulation carriage of information at 1-2 bits/sec. The 10 Mc/s. carrier is mixed at 3 with an n frequency stepped signal (10-20 Mc/s.) from frequency synthesizer 4 under the control of driving oscillator 5 and programme selection device 6. The steps are at 100 per second. A filter 8 and amplifier 9 process the carried before transmission. At the receiving system, Fig. 2, the local oscillator produces an n stepped frequency waveform by means 24, 25, 26, 27, respectively similar to means 4, 5, 6, 7 but with frequency is the range (20-30 Mc/s. + IF). An IF signal at constant frequency is thus produced by mixer 23 and fed, via variable phase-shifter 28, narrow band filter 29 and amplitude limiter 30, to one output of a phase detector/mixer 31. An IF stable oscillator 32 feeds the second input of mixer 31 such that it gives an output indicative of the phase difference for each frequency step. This output is changed to digital form in A/D converter 34 and fed, via digital adder 35 to an n position shift register 36 shifted in synchronism with the frequency stepping. As a phase value for the rth step in the pth pattern is read out of the register, the phase value for the instant rth step is the (p+ 1)<SP>th</SP> pattern is being fed into the register, and the two values are combined at 35. Thus the pth pattern values are used to control the phase shifter 28 during the passage therethrough of the (p+1)<SP>th</SP> pattern. The output of the mixer 31 is thus tended to zero. The phase reversals caused by the informations key are extracted by means 37. The amplitude of the IF signal may also change from step to step and this is counteracted by a similar zero control system, Fig. 3 (not shown), using an A.V.C. amplifier instead of phase shifter 28, and a subtractor instead of mixer 31, the whole control system substituting for limiter 30.

Abstract: 664,540. Cash registers. FAIRWEATHER, H. G. C. (Ericssons Kassaregister Aktiebolag L. M.). April 8, 1949, No. 9626/49. Class 106 (i). A cash register prints the total of previous items with each item in order to eliminate independent totaltaking. Differential amount-setting levers 8 actuate pairs of type rolls 9 and 10 for printing items in duplicate on the two halves of a record slip inserted in a slot 5. Coaxial with the rolls 10, which print the salesman's half of the record slip, is a totalizer comprising total - printing type rolls 28 adapted to be coupled to the itemprinting rolls 9, 10 by coupled pairs of spur gears 24, 26 in a rocking frame 22. Rotation of the main shaft 6, after release by a key 40, first, through a cam 19, trips printing hammers 18 to print the item and the previous total then standing on the totalizer. The frame 22 is then rocked to engage the gears 24, 26 for coupling the setting and totalizer rolls. Finally, a cam 46, driven by the main shaft 6, raises a bar 44 to restore the setting levers 8, so transferring the amount set on the rolls 9, 10 to the totalizer to be included in the total printed at the next operation. Totals are printed upside-down in relation to the items. A counter 41 operated by the main shaft 6 prints a serial number with each item by means of rolls 42. Transfer mechanism. Transfer between orders of the totalizer is made by a pawl 33 on a lever 30 rocked by a cam 31 on the main shaft 6. Normally a detent 34 holds the pawl inoperative against the action of a spring 35. When the next lower roll completes a revolution, a pin 39 thereon releases the detent from the pawl, through the intermediary of an arm 37 on a fixed pivot 36, so that the pawl is effective when the lever 30 is rocked. The pawl is re-engaged with the detent 34 by contact of its tail 43 with the fixed pivot 36.
