Patent GB-1464093-A (GB)
Title: Power control apparatus
IPC: G05F1/455
Filed: 1974-05-21
Abstract: 1464093 Touch responsive switching systems THORN DOMESTIC APPLIANCES (ELECTRICAL) Ltd 21 May 1974 [21 Feb 1973 22 March 1973 13 March 1974 26 April 1974] 8392/73 14014/73 11100/74 and 18494/74 Heading G1N [Also in Division H2] Power control apparatus comprises a memory 1 for storing a variable numerical value, a circuit connected to an output of the memory for varying. the rate of energy supply to a load 10 in dependence on the value stored in the memory, a manually operable switch 2 for increasing the stored value and a manually operable switch 3 for decreasing the stored value. The memory may be a shift register or a counter, the input 16 of which is supplied with pulses derived from the 50Hz mains supply. Each of the switches 2, 3 and a reset switch 4 is a capacitive proximity switch which produces an output when its surface is touched by an operator. A display 6 in the form of a seven segment light emitting diode or liquid crystal display, nixic or neon tubes or tungsten lamps indicates the number stored in the counter. The output of the counter is fed to a pulse generator 7 which includes a digital to analogue converter 22, a delay switch 8, a ramp generator 23 and a comparator 27. The output of the comparator switches on a triac 9 connected in series with the load 10 only when the ramp voltage is less than the output voltage of the delay switch 8. Power is therefore-supplied to the load, which may be a heating element of an electric cooker, a gas control valve of a gas cooker, a lighting arrangement or a motor, the power being supplied as bursts of A.C. The lengths of the bursts in relation to the gaps between the bursts is determined by the number stored in the counter. If the count is increased by touching the switch 2, an input 24 to the delay switch 8 causes the delay switch to produce a voltage corresponding to maximum heating of the load. When a predetermined temperature is reached an infrared sensor 15 causes the circuit to return to the control of the triac by the converter 22. Similarly if the count is decreased by touching the switch 3, an input 25 to the switch 8 causes the switch to produce a zero output voltage to quickly cool down the heating element until the sensor 15 returns the circuit to control by the converter 22. In a modification of the generator 7 the output of the memory controls a variable resistance connected to a diac in the gate circuit of the triac. Instead of using a triac, a power transistor may be connected in series with the load in a D.C. circuit.

Title: Manufacturing method of invisible cigarette tips
IPC: A24C5/56
Filed: 1935-03-20
Abstract: Invisible cigarette tips are produced by applying to the paper solutions of colourless and odourless cellulose derivatives which, after drying, show the structure of the paper unaltered.  The tipping solution may be applied to the paper as it leaves the bobbin on its way to the cigarette machine.  Cellulose esters or ethers, such as cellulose nitrate, acetate, xanthate, ethyl ether, &c., dissolved in methylacetate, methylchloride, &c. may be used. Softening-means such as phthalates may be added, and if desired menthol or other aromatic substances.  Phosphates may be added to render the tips non-inflammable, and fats &c. to make the paper appear more or less transparent.  An example of tipping-solution comprises a 30 to 40 per cent solution of acetylcellulose in equal parts of methylacetate and acetone, to which is added 3 per cent phthalates, and if desired 3 to 5 per cent fat or wax, 1/2 to 1 per cent menthol, and 3 to 5 per cent phosphates.

As shown for a flute of 16 holes, the keys c of the pads controlling the four lowest holes 1 - - 4 are brought near the holes 9 .. 12, and the keys f of the pads controlling the four highest holes 13 - - 16 are brought near the holes 5 - - 8. The pads 9 - - 12 can be simultaneously depressed by a bar h, with finger-piece h<1>, which lies over them. The pads 5 - - 8 are depressed by a bar g lying over them, which bar is pivotted co-axially with, and also lies over, the bar h, so that pads 9 - - 12 are also depressed by the bar g. The pads 13 - - 16 are normally held closed by a 'bar i lying under the outer parts of the keys f. On depression of the bar i, pads 13 - - 16 are permitted to rise and can be closed by independent finger action. To prevent bars h, i from being operated at the same time, a rocking lever may be placed with its arms under their finger-pieces. Adjustable bearing screws may be provided at the points of engagement of the bars and padlevers. These screws may be brought out of contact when desired in transposing. The bearing parts of the bars may also be formed of arms which are movable out of contact with the pad-levers when desired in transposing. The invention permits the adoption of a simple fingering on a chromatic basis for all notes not requiring cross-fingering.
