Title: Improvements in or relating to window friction balances
IPC: E05D13/00
Filed: 1961-03-25
Abstract: 970,649. Frictional balance for vertically sliding windows. A. KAUFMAN, and L. KAUFMAN. March 25, 1961, No. 10984/61. Heading E1J. A friction balance for a vertically slidable window 1, formed with U-section channels 6, 7, 8 extending along its vertical side edges, comprises a pair of frictional units, mounted on arms 18, 19 between guides 4, 5 on opposite sides of the window frame F, which act in the U-section channels. Each unit is of rectangular prismatic form and includes a side wall 14 with a frictional pad 42, riveted thereto, which coacts with channel wall 8, a base 13 with an aperture 15 adjacent side wall 14 into which extends a lip 27 of a pivotable L-shaped member 25, 26 and the end of a member 30 which can be adjusted vertically by a screw 35 and which is held in position by a spring 38. A frictional pad 44 is secured to arm 26 of the L-shaped member, which during upward movement of the window, Fig. 5, pivots out of contact with its coacting channel wall 7. During downward movement of the window the pad 44 is drawn into a vertical position and the amount of frictional force it exerts on the channel wall is determined by the position of the end of arm 30 which acts as a stop against sliding movement of the L-shaped member towards side wall 14. Specification 740,223 is referred to.

Title: Multi-process control system for an electrophotographic printing machine
IPC: G03G15/043
Filed: 1975-03-17
Abstract: 1497289 Electro-photography; automatic control systems XEROX CORP 17 March 1975 [18 March 1974] 11005/75 Headings G2H and G3R Xerographic drum 10 includes a probe 16, which may be either fixed in the drum or movably mounted on it, and is so constructed as to mimic the response of the photo-conductive surface of the drum as it passes through xerographic processing stations and to generate outputs representative of the response. The probe may comprise a transparent, electrically conductive sheet 73 secured over the photo-conductive material 12 of the drum by a layer of insulating cement 80, with an electrically conductive lead 81 secured to the sheet 73. The voltage between the sheet 73 and electrically conductive substrate 74 is monitored, and gives an indication of the condition of the material 12. Comparison of the voltage produced with a succession of references gives a corresponding succession of error signals, as the probe passes the processing stations, and enables the processing stations to be controlled. Control. The processes controlled are (i) voltage of initial charge by a corona device, (ii) intensity of lamps which illuminate the document to be copied, (iii) development of the image by magnetic toner, by control of the voltage on developer rolls (three colour), (iv) the voltage on a transfer roller and (v) the concentration of toner particles in the developing medium. In each case, measurement of the variable controlled is by detection of the charge remaining on the probe after the respective process; this is sampled once per revolution at the appropriate point and stored on a capacitor for the next repetition of the operation. It is then compared with a respective reference voltage, and if greater than the reference a silicon control switch locks in, to change the state of a flip-flop, the output of which operates a controller for the process.

Abstract: An aqueous composition for treating films or textiles comprises an aluminium oxide aerogel, a copolymer of acrylic acid and acrylic acid methyl ester and a fatty acid and/or fatty alcohol-ethylene oxide condensation product.ALSO:Textile materials are treated with an aluminium oxide aerogel obtained by thermal hydrolysis of aluminium chloride by known methods.  The aerogel may contain subordinate amounts of silica or titanium dioxide.  The amount of aerogel deposited may be between 0.05 and 10 per cent of the weight of the fibres, and it may be applied in aqueous suspension by dipping or spraying, by dusting on as a dry powder or by printing in a paste comprising a thickening agent, the material being thereafter steamed. The aerogel also may be applied in aqueous compositions comprising non-ionic or cationic surface-active agents, protective colloids, acids, alkalis, bleaching compounds, dyestuffs, mineral oil, grease or synthetic resins.  When applied in aqueous compositions, excess liquid may be removed by centrifuging and the materials dried. Examples describe the treatment of cotton, wool, cuprammonium rayon, acrylonitrile and polyamide fibres.  The treated fibres may be blended with other fibres, woven into blankets or used for the pile in pile fabrics.
