Title: Improvements relating to washing machines
Inventor: EASTALL MARTIN HAROLD
IPC: D06F34/08
Filed: 1967-01-16
Abstract: 1,209,052. Automatic control of level and temperature. HOTPOINT Ltd. Jan. 16, 1968 [Jan. 16, 1967], No. 2229/67. Heading G3R. [Also in Divisions D1 and H3] An automatic washing machine control (see Division D1) comprising a semi-conductor liquid level control circuit which initiates an operation of the machine when a particular level is reached and incorporates a delay to prevent re-opening of the liquid supply when the liquid level falls temporarily due to turbulence. The washing motor is initially energized through normally closed contacts S1 controlled by coil S connected in an emitter following circuit of a Schmidt-trigger circuit A which includes transistors T 1  and T 2  controlled by a transistor tuning circuit B as the change over contact S2 of the relay in temperature circuit C initially engages contact b. During a preliminary operation, relays will be de-energized until the voltage output from circuit B builds up on capacitor C2 sufficiently to trigger circuit A. This energizes coil S to open contacts S1, deenergize the motor change contact S2 from fixed contact b to fixed contact c connected to the output of semi-conductor sensing circuit C. Capacitor C2 follows the voltage at contact b and sufficient charge is stored in capacitor C2 to keep circuit A triggered and coil S energized. Circuit C includes thermistor TH which responds to the wash liquid temperature and is connected through switch SW and resistors R1, R2, R3 corresponding to warm, hot, very hot. The output voltage of circuit C is maintained sufficiently high, until the temperature of the washing water has reached the required temperature, to hold coil S energized and therefore prevent the washing motor from starting. In a modification, Fig. 3 (not shown), diode switching is used instead of contacts S2. The liquid level control, Fig. 4, is connected by diode D3 to timing circuit B, sensing probes SP1, SP2 being fitted to the sides of the washing machine corresponding to full and half load operation levels. Relay R controls contact r controlling the solenoid operated hot and cold water valves and contact r1 for controlling the voltage supplied to contacts S1 of the relay controlling the washing machine motor. In operation, when the bowl is empty, the base of transistor T5 is cut off and point "e" is at earth potential, relay R is de-energized and contact r operates to open the water valves. The diode D3 keeps the voltage on timing capacitor C1 at earth potential e so that the timing circuit does not operate until the water is at the required level when a circuit is made through probe SP1 or SP2 and the water to earth. Thus relay R is energized, contacts r, r 1  are closed and the water valves are closed and the motor is energized. At the same time, diode D3 is reverse biased and capacitor C1 can begin to charge. Condenser C3 causes sufficient delay to prevent de-energization of the circuit in the event of the pulse being temporarily dry.

Title: Improvements in multi-ply paper rolls suitable for use in typewriters, tabulating machines or the like
Inventor: FRANCIS FREDERICK GEORGE

Abstract: 724,545. Multi-ply paper rolls. CARIBONUM, Ltd. Aug. 31, 1953 [Jan 30, 1952], No. 2769/53. Class 16. A multi-ply paper roll for use in typewriters, cash registers and like writing machines has an adhesive composition applied at one or both edges of the paper sheets forming the roll in order to introduce sufficient restraint to prevent movement between adjacent sheets during their passage through the machine. A solution of glue in water may be used or a suspension of rubber latex in water or a solution of chlorinated rubber suitably plasticized and dissolved in toluene or similar solvent. The adhesive used is fairly dilute to allow subsequent separation of the plies. The adhesive may be applied to the edges of a single group of sheets while it is being wound, the adhesive preferably being dried at least partially before it comes in contact with the next layer of the roll. The adhesive will have a tendency to spread inwardly along the surfaces of the paper which increases the securing effect. Alternatively the adhesive may be sprayed onto the already wound roll which has had its ends trimmed to present a flat surface. The adhesive will again slightly penetrate the layers of paper. The layers will unwind easily but the individual plies will stick slightly together.

Title: Improvements in or relating to the production of cellulose derivatives

Filed: 1942-03-06
Abstract: 556,664. Cellulose ethers. SHARPHOUSE, J. H., HAWTIN, P. R., DOWNING, J., and GROOMBRIDGE, W. H. March 6, 1942, Nos. 2943 and 7865. [Class 2 (ii)] The clarity of a cellulose ether is improved by dissolving it in a solvent liquid, partially precipitating it by incorporating a non-solvent for the ether with the solution and then extracting the precipitate with a liquid which is a solvent for only part of the ether treated. The extraction liquid may be a mixture of a solvent and a non-solvent for the ether. The liquids employed are preferably such that the lower clarity fractions remain in solution or are dissolved. The treatment may be carried out at room temperature or at elevated temperature Preferably the treatment is carried out on a cellulose ether from which caustic soda and other constituents of the etherification mixture have been removed by washing. The treatment may be applied to ethyl celluloses of 40-50 per cent. ethoxy content and soluble in a mixture of toluene and ethyl alcohol. For the clarification of such ethers a lower fatty acid such as acetic, propionic, or butyric acid may be used. The ether may be dissolved in the anhydrous acid or a strong solution thereof and precipitated by the addition of water or a dilute aqueous solution of the acid. The precipitate may then be extracted with an aqueous solution of the acid. Methyl, butyl, benzyl, and other cellulose ethers may be similarly treated. Instead of fatty acids, there may be used other liquids for the extraction, e.g. alcohols, toluene, dioxane, acetone, petrol ether, or ligroin, as solvents or non-solvents according to the nature of the ether under treatment. The extraction liquids may contain bleaching agents. The operations of solution, precipitation, and extraction may be repeated several times if desired.

Title: Improvements in or relating to circuit arrangements for calculating control characters for safeguarding series of information characters
IPC: H04L1/00
Filed: 1966-01-24
Abstract: 1,098,772. Checking arrangements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 24, 1966 [Jan. 27, 1965], No. 3089/66. Heading G4A. A control (i.e. check) character is calculated by using the data characters to control supply of pulses to a cyclic modulo-M counter which, on reaching its end position, causes all subsequent pulses derived from the current data character to be counted twice. A series of control characters P j  are each calculated as a weighted sum of the data characters Z i , the weights being integral powers of two, as follows. Each data character Z i  causes a pulse generator C to supply 2M -Z i  pulses to the counter R. A carry pulse from the counter sets a flip-flop FF so that each subsequent pulse from the generator is gated through an inverter V to the counter R as well as reaching the counter direct and is therefore counted twice. The flip-flop FF is reset after each data character. When all the data characters have been used, the control character is present in the counter, which is reset before calculation of the next control character. Transmission of the data is checked by recalculating each control character as above and then applying the transmitted control character P j  to the pulse generator C thereby adding 2M - P j  into the counter which should then read zero.
