Title: A method of cosmetic treatment
Inventor: WILLIAMS WOODROW R
IPC: A61Q9/00
Filed: 1989-06-14
Abstract: A method of cosmetic treatment for the skin comprises applying steam to the skin for a predetermined period, and then applying a hydroxy-tricarboxylic acid to the skin, either alone or in composition which is left on the skin for a predetermined period and is then removed. It has been found that using such an acid, or a composition containing it, on the face in the presence of steam tightens up the skin, and gets rid of lines and wrinkles and bags around the eyes. It also softens the skin, heals any scar tissue and removes acne and spots. The acid is also able to remove facial hair and reduce fatty tissue. Preferably, the acid is citric acid in the form of lime juice and/or lemon juice.

Title: Data decoder
Inventor: BHANDARI RAJAN
IPC: H04N7/26
Filed: 1991-10-04
Abstract: A data decoder is described for decoding associated first type code word [RUNLENGTH, SIZE] and second type code word [AMPLITUDE] pairs, each said first type code word serving to define a runlength of constant values preceding a variable value defined by a following second type code word. The first type code words and the second type code words are fed to respective first and second pipeline delay units 22 and 24. The output from the first pipeline delay unit 22 is fed to a state machine 26 which reads the RUN LENGTH value and generates an INSERT ZEROS signal for a period proportional to the RUN LENGTH value followed by a signal triggering reading of the second pipeline delay unit 24. The INSERT ZEROS signal and the output of the second pipeline delay unit 24 are fed to a multiplexer 28 which selects between them to generate the appropriate OUTPUT signal. A swing buffer 10 is disposed upstream of the first and second pipeline delay units 22 and 24, The second pipeline delay unit 24 is also used to effect fixed length code decoding (dashed code words in unit being as yet undecoded). <IMAGE>

Title: Motor control device for controlling motor speed depending on imparted load
Inventor: KOBAYASHI NORIO
IPC: B41J2/485
Filed: 1992-06-15
Abstract: A motor control device for a motor (14) capable of stably operating one of a plurality of mechanisms whilst reducing the influence of a load imparted on the motor (14) and attributed to an operation of another one of the mechanisms. A CPU (70a) suitably controls or selects an electrical current level provisionally ranked and stored in a ROM (70c) to the motor (14) which drives a print hammer for obtaining a predetermined velocity of the hammer. When the print hammer reaches its decelerating phase, the CPU determines an inverse electrical current level and/or an inverse electrical current applying period for application of an inverse electrical current to the printing motor on the basis of the rank of the electrical current in that phase. The electrical current corresponds to the load on the motor. In an electronic typewriter, a single motor controls a print hammer drive mechanism, a holder member position shifting mechanism, a printing ribbon takeup mechanism and an erase ribbon takeup mechanism. <IMAGE>

Patent GB-930151-A (GB)
IPC: B01D53/24
Abstract: 930,151. Separating gases. UNITED STATES ATOMIC ENERGY COMMISSION. March 15, 1960 [April 1, 1959], No. 9102/60. Class 1(1) Gaseous mixtures are separated by expanding into a low pressure zone through a nozzle to form a jet comprising a supersonic core having an outer annular shock zone and separately withdrawing lighter and heavier fractions respectively from said shock zone and the inner part of the supersonic core. The process may be applied to the separation of oxygen and nitrogen in air and to the separation of isotopes; in the latter case a large number of expansion/separation stages may be employed, a product gas of one stage being employed as feed gas in a subsequent stage. Fig. 2 illustrates the preferred apparatus in which the mixture to be separated is supplied from valve-regulated supply tank 16 to stagnation tank 14 and thence through a converging-diverging nozzle 17 into tank 11 having a vacuum conduit 12. A probe assembly 22 comprises inner and outer cylindrical tubes defining an annular orifice 27 leading to an evacuated chamber 26 having a vacuum conduit 29 for the lighter gas and a circular orifice for the central part of the supersonic core 19, connected to a vacuum conduit 28 for the heavier component. The nozzle and probe may be of rectangular, e.g. slit-shaped cross-section, rather than circular. The Specification discloses the pressure conditions necessary to achieve supersonic flow from nozzle 17 and illustrates graphically the variation in concentration and pressure of one component of a gas stream at right angles to the direction of flow in the supersonic gas stream. Reference has been directed by the Comptroller to Specification 794,834.
