Title: System for supplying controlled amounts of at least one liquid product to a washing machine
IPC: D06F34/08
Filed: 1972-12-15
Abstract: 1382899 Dispensing liquids ECONOMICS LABORATORY INC 15 Dec 1972 [22 Dec 1971] 57949/72 Heading BIC [Also in Division D1] The invention relates to a system for automatically dispensing predetermined quantities of at least one liquid product in a carrier liquid to a washing machine having a main water supply controlled in a predetermined machine cycle. Illustrated is a washing machine 12 to which liquid products in containers 15a-15e have to be fed. A conduit 18 conducts a carrier liquid, water, therethrough. Electrically actuated valves 25a-25c are positioned in the conduit. The conduits leading from the valves pass through siphon breakers 28a-28c and then may divide into two. Namely conduit 18a passes into conduits 19a and 19b, conduit 18c passes into conduits 19d and 19e whilst conduit 18b passes into conduit 18c. The conduits 19a-19e have venturi-aspirators 30a-30e to which conduits 16a-16e are connected. A trigger signal generating means 20 associated with the washing machine generates signals to activate valves 25a-25c. Appropriate circuitry allows the valves to be operated for a predetermined time irrespective of the length of time of the signal.

Title: Analogue-digital converter using an integrator
IPC: H03M1/00
Filed: 1970-12-07
Abstract: 1338390 A/D converter IWASAKI TSUSHINKI KK 7 Dec 1970 [8 Dec 1969 (2)] 58006/70 Heading G4H A dual ramp analogue to digital converter of the type in which the analogue input is applied to an integrating capacitor for a time period which is measured from the time the voltage on the capacitor passes a threshold value by counting a fixed number of pulses from an oscillator and then is replaced by a reference signal of opposite polarity for a time period which is measured by counting pulses from the oscillator, until the threshold is again passed, is provided with a store for storing the contents of the counter, and a comparator for comparing the contents of the counter from one cycle with the contents of the store, i.e. the count from the previous cycle. The oscillator being a variable frequency oscillator the frequency of which is changed when the comparator detects a difference. In operation the contents of the counter are stored and the cycle is repeated. If the new contents of the counter and the stored value differ, e.g. due to noise effects, the frequency of the oscillator is changed and the operation is repeated until the counter and store contents match. Thus the effects of noise signals having different periods may be eliminated by selecting a frequency such that the periodic noise signals cancel over the period in which the input signal is integrated. The comparator may consist of two D/A converters (which are not described) and a difference amplifier. The comparator may also be a digital subtractor. The output of the comparator may be fed to a pulse generator which produces a pulse having the same polarity as, and a magnitude proportional to, the comparator output. The pulse generator then feeds the variable oscillator to step up its frequency. When the oscillator has been swept through all its possible frequencies it returns to its start frequency and repeats the sweep.

Title: Coded information transmission systems
IPC: H04L27/20
Filed: 1972-12-07
Abstract: 1374786 Digital transmission; phase modulation POST OFFICE 7 Dec 1972 [23 Dec 1971] 60062/71 Heading H4P  A four phase switched modulator has two substantially identical parallel channels, one including a directional coupler introducing a 90 degree phase shift. Each channel has alternative paths one of which also has a phase shift of 90 degrees, effected by couplers, the paths being selectively operable by serial unilaterally conductive devices responsive to pairs of digital signals of opposite polarity. An input carrier is divided equally by resistors 2-4 one half being passed through terminal 5 via directional couplers 15, 16 in tandem to a transmission line 14, also receiving bipolar digital input at 6. The second output of coupler 16 is connected to a resistive termination 17. Line 14 output passes through a diode 18, quarter wave stub 22 to line 8 and is also coupled through directional coupler 31 to line 30 terminated at both ends by resistors 32, 33. Line 14 output also passes through reverse connected diode 19 and quarter wave stub 23 to terminating resistor 24 and is also coupled through 26 to line 25, terminating in resistors 27, 28 and thence through coupler 29 to line 8. The other half carrier proceeds via an identical channel. Each coupler introduces a loss of 3dB; terminating impedances match impedance of lines to avoid reflections.  The bipolar signal at terminal 6 causes one diode, say 19, to conduct hence the carrier is routed to line 21 and hence by couplers 26, 29 each imposing a 90 degree shift to line 8; alternatively conduction of diode 18 results in no phase shift hence signals at terminal 6 are represented by 0 or 180 degrees phase shift at terminal 8. The other channel acts similarly but an additional 90 degree shift is introduced by coupler 12 hence bipolar signals on terminal 10 are represented by 90 or 270 degrees at terminal 8. In an alternative arrangement, Fig. 2 (not shown), control of the passage of carrier is effected at the ends of the paths instead of at the beginning, i.e. carrier and digital signals are fed to opposite ends of the arrangement providing the advantage that carrier amplitude at the diodes is smaller.

The current yield may be 70 per cent or more. The cathode material may be superficially oxidized by heating to 500-600‹C. in air; current yields of 90 per cent or more may then be obtained. In an example the cathode consists of ten tungsten wires with 20 cms. depth of immersion at a distance of 10 cms. from an anode consisting of two lead plates of total surface 8oo sq. cms., the bath containing 100 gms. of chromic sulphate and 350 gms. of sulphuric acid per litre. In another example the cathode consists of two molybdenum wires of 0.5 mm. diameter and 20 cms. depth of immersion at a distance of 10 cms. from an anode consisting of a lead plate of I20 sq. cms. area.

Abstract: A high velocity forging machine employs a relatively lightweight ram or hammer (10) which is driven by a spring (32) of high spring rate during its working stroke. The hammer velocity will be at least 30 ft/second upon impact and because of the high velocities employed the machine can deliver as much energy as a conventional drop forging machine employing a heavier hammer. The hammer (10) may be raised manually or by means of a suitable clutch- controlled drive arrangement; in both cases, the hammer is arranged to be released instantaneously so that the spring energy acts solely on the hammer. <IMAGE>
