Title: Improvements in or relating to clothes washing machines
IPC: D06F13/00
Filed: 1947-07-03
Abstract: 640,020. Washing and drying machines RAND WASHING MACHINE CORPORATION, H. J. July 3, 1947, No. 17558. Convention date, July 9, 1946. [Class 138 (ii)] A clothes washing and drying machine comprises a flexible liquid and air-tight bag or lining element 7 having an opening sealed by a cover 15 and containing agitating means 9 together with means for withdrawing liquid and air from the element 7 to create a substantial vacuum therein to squeeze liquid from laundry inside the element by pressure against the outside of the element. The element 7 is in the form of a flexible water-tight bag 7 which is sealed to the top of a tub 6 around its opening which is normally sealed by the cover 15. The agitating means comprise an impeller 9 and the bag 7 is sealed around the agitator shaft 10 to prevent leakage. An opening 12 is provided in both the tub and bag for a pipe 13 and the tub also has openings 14 at the top to allow air to enter between the tub and bag. The pipe 13 is connected through valves 1 ... 4 to a pump 20, a drain pipe 28 and a watermixing device 19 which is connected to hot and cold water pipes 17, 18. The operation may be automatically controlled by a clock-controlled switching device 21. In use the clothes undergo soaking, washing, rinsing and drying operations. The first three are similar, water being admitted to the bag by closing valves 2, 4 and opening valves 1, 3 and removed by opening valves 2, 4 and closing valves 1, 3; pump 20 is operated for both purposes and the impeller is run during the washing phase and if desired during the others. Soap is added manually during the washing phase. For the drying phase the pump is left running after it has drained the water at the end of the rinsing phase and so exhausts air from the bag. Atmospheric pressure on the outside squeezes the clothes against the impeller (which is stationary for this phase). The impeller has perforations 29 in its surface and acts as a strainer and so forces the water from the clothes. This phase is ended by opening valves 3, 4 and closing valves 1, 2 which admits air to the bag. The clothes may then be removed. Air or fluid pressure may be applied to the outside of the bag during the drying phase.

Title: Digital data signal decoding apparatus
IPC: H04L7/00
Filed: 1974-04-25
Abstract: 1425796 Digital storage systems INTERNATIONAL BUSINESS MACHINES CORP 25 April 1974 [21 June 1973] 18053/74 Heading G4C A decoding system for decoding successive data words, each having the same number of serial signals, includes more than one decoder, different decoders receiving different groupings of the signals. When a synchronization block is detected by a detector associated with a respective decoder the decoded signals from that decoder are passed to the output. The signals may be read from a magnetic tape on which they are recorded in successive sections, each section consisting of a number of data blocks and terminating in a sync. block. Each block consists of a number of words and each word consists of two bits, for example. As indicated in Fig. 3, the signals pass to shift register 350 which may be regarded as comprising upper and lower registers 308, 303. The signals are shifted through the registers wordwise, i.e. 2 bits at a time. Detectors 311, 312 inspect portions of the signal sequence displaced by one bit: had each word consisted of n bits there would be n registers and n detectors to accommodate n possible groupings of the bit signals. Similarly, decoders 304, 305 receive 1-bit displaced 6-bit portions of the signal sequence to pass a single bit to buffers 306, 307 after each 2-bit shift of the signals in the register 350. Each buffer can store the decoded signals relating to a full section. During the passage of the signals through register 350 only one of the detectors will recognize the sync. block, and only the corresponding buffer 306 or 307 contains the correctly decoded signals. If the sync. block is detected within a certain time of its theoretical position, as dictated by counters 313, 314, the relevant buffer is read out.

Abstract: 699,183. Electrically-released switches. BESCOCCA, L. July 21, 1950, No. 18241/50. Class 38 (v) An automatic device for controlling an electric circuit, a fluid valve or an alarm in response to a predetermined condition, e.g. temperature, fluid pressure, or overload in an electric circuit, comprises a control member frictionally held in one position against the action of a biasing force, the frictional effect being reduced by the condition so that the member is moved by the biasing force to effect a control function. As-shown, the member is a U-shaped wire spring 15 fixed to a terminal 13 and having a forked projection 17 which is normally held frictionally between fixed and movable plates, 22, 26 respectively by means of a "hot wire" 25 stretched between plate 26 and an adjusting screw 31, which forms one terminal of the switch, the other being formed by a metal ferrule 10 welded to the terminal 13. An increase of current through wire 25, causes it to stretch and reduce the pull on plate 26 so that the bias of the spring 15 overcomes the frictional effect so as to open the circuit, the spring moving to the dotted position. The switch is reset by moving knob 20 to the left, and the tripping movement of the knob may control a toggle switch.

Title: Process for the isolation of cholesterol from wool-wax alcohols
Inventor: HEWETT COLIN LESLIE
Filed: 1950-07-21
Abstract: Cholesterol and isocholesterol are separated from wool-wax alcohols by first crystallizing the isocholesterol from a solution of the raw product in a mixture of benzene or its lower homologues (e.g. toluene or xylene) and methanol (the proportion of the latter preferably being between 40 and 80 per cent by volume), and thereafter separating the cholesterol from wax-like impurities by selective crystallization from, or selective dissolution of the impurity by, a simple fatty acid (e.g. acetic or propionic acid) under carefully regulated temperature conditions over the range of 27-45 DEG  C. (preferably about 30-35 DEG  C.).  Advantageously the initial solution is prepared from wool-wax alcohols melted at about 60 DEG C. and dissolved in 2 1/2 volumes of the mixed solvent, and is seeded with isocholesterol and cooled gradually to about 20-30 DEG  C., thereby ensuring the formation of relatively large crystals of isocholesterol and facilitating the separation thereof by filtration, which step is followed by evaporation of the solvent to provide the starting material for the final fractionation step.  The cholesterol obtained thereby may be further purified by recrystallization from alcohol (e.g. industrial methylated spirit).  Examples illustrate the use of the solvents specified above under various conditions.
