Abstract: 314,743. Wi11iams, W. G. Nov. 3, 1928. Ornamenting.-Coverings for walls, tab1es, and other surfaces, representing marble &c., are formed by ornamenting sheets of g1ass or other transparent or translucent material as fo11ows :- The side of the material which is to be secured. to the wall or other surface is coated with paint which mav be in various densities in different zones, and, while this coating is still wet, one or more further coatings is of paint, of a thicker consistency than the first 1ayer, are applied. The second layer can be applied uniformly or in patterns, and can consist of one or more colours. While still wet, a liquid, which is capable of removing some of the colour, is applied. Preferab1y a hydrocarbon such as petrol is employed, and the colour may be completely or partially removed. The liquid can be applied by spraying through a stencil or by means of absorbent pads supported adjacent the painted surface by a network, to enab1e a pattern to be produced. The sheets are allowed to dry, and a further 1ayer of colour is then applied in the form of an oil or turpentine varnish paint, and of a different colour, preferab1y darker than the first 1ayer, so that it is visib1e through the front side of the materia1. The sheets are secured in position on a wall or other surface by the use of a pasty composition consisting of sawdust, plaster of Paris, whiting, 1inseed oil, and paraffin oil. Any gaps between adjacent sheets are fi11ed with a coloured stopping such as washable distemper.

Title: Processing of lignite
IPC: C07C51/29
Filed: 1955-11-10
Abstract: Water-soluble carboxylic acids are obtained from lignite containing at least its natural moisture content by subjecting it to partial oxidation with an oxide of nitrogen, e.g. nitrogen dioxide, or a halogen, e.g. chlorine or bromine, and recovering the carboxylic acids from the treated lignite, e.g. by washing with water.  The lignite may be treated as a slurry and in the early stages of the oxidation nitric acid may be added.  The temperature at which the partial oxidation is carried out may be between 20 DEG  and 380 DEG C. and the oxide of nitrogen or halogen may be passed together with air and hot products of combustion through the lignite. Alternatively the lignite as a slurry may be heated directly by a flame submerged in the slurry, the oxidizing gas being introduced around the submerged flame.  In an example lignite was treated with a gas containing nitrogen dioxide for 4 hours at about 120 DEG  F.  A cyclic polycarboxylic acid was extracted with water from the residue remaining in the treatment vessel and additional quantities of the acid were recovered from a condensate obtained by cooling the gases and vapours leaving the treatment vessel.

Filed: 1928-11-05
Abstract: 300,502. Saussard, L. Nov. 12, 1927, [Convention date]. Combined fixed and moving cylinder pumps; regulating delivery by bye-passes; regulating delivery by varying power of motor.-In a pump of the kind comprising two ported pistons 2, 3 reciprocating at right angles to each other, the outer one in a fixed casing 1 and the inner one inside the outer one, the shaft 5 carrying the actuating eccentric 4 engaging the piston 3 is driven by a shaft 16 which is coupled at one end to the shaft 5 by a clutch 17 and at the other end to a driving motor. The shaft 16 has a tapered journal 19 pressed against the end of the bearing, 18 by a spring 20. A bye-pass channel 23 between the inlet 13 and delivery 12 is normally closed by a valve 24 carried by a diaphragm 25. When the pressure in the pump is excessive, it acts on the inner face of the diaphragm through a port 26 and opens the valve 24 against the action of a spring 27. Inlet and delivery channels 15, 14 are formed in the shaft 5. In another form, the inlet port is near the driving end of the shaft 5, so that the stuffing- box 21 may be dispensed with. The pump may be driven by an hydraulic motor 29, Fig. 5, driven by pressure oil admitted by a pipe 30 controlled by a valve 24. This valve is carried by a diaphragm 25 open to the pump delivery pressure through a port 12, so that when the pressure is excessive the supply of oil to the motor is reduced.

Title: Circuit arrangement for compensating drop-out in the repro duction of signals recorded on a record carrier
IPC: H04N5/92
Filed: 1972-07-12
Abstract: 1332279 Drop-out detector PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 July 1972 [15 July 1971] 32570/72 Heading H4F In drop-out detectors for video recorders, the detection at 14, Fig. 1 of a drop-out in the modulated carrier and the subsequent switchover at 11 from the direct modulated carrier (7) to the modulated carrier of the preceding line (8), often occurs with a delay such that the dropout may not be completely compensated or and/ or the phase of the substituted carrier may not be cophasal with that of the normal carrier. This latter fault is especially important where the carrier is phase or frequency modulated. The invention thus proposes the use of demodulators 16, 17 in both the direct (3) and delayed (4) channels, such that the switch-over operates on the video signal and the inherent delay in the demodulators allows the drop-out to be fully compensated. When the drop-out may last for more than one line the circuit of Fig. 2 is used, the detection of a drop-out, as well as causing switch-over of 11 as before, causing the connection of a feed back loop 22 between the one line delay 13's output and its input. The last line before the drop-out is therefore continuously stored in loop 21, 13, 23 until the drop-out ceases. The demodulator of Fig. 3 is used where zero crossover modulation of the carrier is used and consists of a limiter 25 squaring off all the input cycles to a pulse train, a control transistor 27 and a low pass filter or integrator 24, producing a D.C. voltage including the video signal. The capacitor 29 is adjusted to give equality of D.C. levels in the two demodulators.

Title: Electrical control signal generator for the control of motion  of a body movable over a predetermined path
IPC: B66B1/16
Filed: 1972-07-12
Abstract: 1390380 Controlling lifts; square root generators INTERNATIONAL PROPERTY INVESTMENTS Ltd 12 July 1972 [19 July 1971] 32675/72 Headings G4H and G4A [Also in Division G3] A positioning system, e.g. for a lift car functions as follows. A call demand indicative of a desired destination of the car is inserted into one input of comparator 11 and, prior to movement of the car, also instigates the operation of an h.f. pulse generator to pass pulses via a control 8 to increment or decrement a counter 9 according to the desired direction of travel of the lift and also to increment, via a divider 12, a second counter 13, the changing count at 9 being used as input to a decoder matrix 10 which provides an output whenever the count in 9 is indicative of a particular destination, the operation of the generator being terminated by either a signal from the comparator 11 indicative of coincidence or by a signal from counter 13 indicative that the count therein is equal to a representation of the maximum velocity of the car, in the first case the signal from comparator 11 instigates movement of the car and causes the control 8 to gate pulses from a displacement encoding scale associated with the car to decrement the counter 13. The output of the counter 13 is taken as input to a D/A converter 14 to produce a decreasing voltage at the output thereof which is applied at one input of an operational amplifier also associated with resistors and a charging capacitor circuit. When the car first starts to move an increasing voltage from the charging circuit is applied to a power controlling circuit of the lift motor until the output of the D/A converter becomes less than this voltage, when the decreasing voltage is applied to cause the car to decelerate. If the h.f. generator is terminated by a signal from the counter 13, the car is also set in motion but the pulses from the encoding scale are gated to the counter 9 until a coincidence signal is produced and the operation continues as above. The number of pulses gated to the counter 9 and divider 12 by the h.f. generator and by the encoding scale are indicative of the distance to be travelled and that actually travelled by the car respectively. Since a velocity is proportional to a distance squared, the divider 12 performs a square rooting function such that the number of pulses fed to counter 13 is indicative of the square root of the distance, i.e. of the velocity required of the car. The square rooting circuit is shown in Fig. 5, and comprises a first counter 16 to which the input pulses are taken and a second counter 17, the outputs of both counters being taken via a comparator G1-G5 to a gate G6 whereby upon equality two pulses are applied via G6 to the second counter and the flip-flop MV produce, on receipt of these two pulses, a single pulse which is the output and which also resets to zero the first counter 16.
