Title: Method and apparatus for electrostatic flocking of the outer surface of objects
IPC: B05B14/00
Filed: 1965-08-25
Abstract: 1,063,677. Coating apparatus. ELOFLOCK OBERFLAECHENVEREDLUNG G.m.b.H. Aug. 25, 1965 [March 5, 1965], No. 36459/65. Heading B2L. In applying flock to the outer surface of hollow objects which have been coated with adhesive the objects are passed between electrodes in a series of electrostatic fields, flock material is supplied to each field and the objects are subjected to electrical potential in each field and earthed between successive fields. In the arrangement shown objects 1 are supported on holders 2 from arms 5 carried on and moved by chain 30 through a series of flocking stations A, B, C. Each arm 5 has a contact 6 which slides on guide rail 7 the latter being divided into conductive sections 7' at the flocking stations and nonconductive section 7" between said stations. The holders 2 are rotated by suitable drive means from a stationary rack (36) (Fig. 3, not shown). The flock material is supplied from above each station (Fig. 2, not shown) from a box (11) and is brushed through a screen by brushes (17) on a driven belt (16), on to a conveyer (10b) which conveys the flock to beneath the path of the objects. A grid electrode (100) is positioned between said conveyer and the path of the objects and a plate electrode (37) is positioned above said path. Surplus flock material is conveyed into hopper (19) and fed back via pneumatic conveyer tube (24) into the box (11). The air is blown through the tube (24) by fan (21) and is maintained at a desired humidity by a water atomiser assembly (25) under the control of a hygrometer (26) in the box (11). To prevent flock straying from one station to an adjacent station grid electrodes 12, 13, 13', connected to an alternating voltage, are positioned between the stations and to screen the boxes 11 against the action of electrical fields, grid electrodes 14 also connected to an alternating voltage are disposed at the outlets from said boxes. The electrodes at each station may be at different potentials appropriate to the flock material being applied at the respective station.

Title: Method of producing colour and similar effects in the mass of hydrogel contact lenses and other hydrogel articles
IPC: G03C1/496
Filed: 1964-09-07
Abstract: 1,057,458. Ornamenting hydrogel articles.   CESKOSLOVENSKA AKADAMIE VED. Sept. 17, 1964 [Sept. 11, 1963], No. 36529/64. Heading B6G. [Also in Division G2] A hydrogel article, such as a contact lens, is coloured or patterned by diffusing into it two chemical agents which react within the interstices of the hydrogel mass to produce a precipitate. For instance, the convex surface of a hydrogel contact lens is laid carefully on the surface level of a 5% by weight aqueous potassium ferric cyanide solution. On to the concave lens surface, a drop of 5% by weight ferrous sulphate solution is applied. Impregnation of both solutions from both surfaces of the lens at the same time causes a Prussian blue precipitate to form in the central part of the lens. Many types of precipitates can be formed within the hydrogel mass; light sensitive precipitates such as silver bromide, which can be exposed, developed and fixed by known photographic processes; and sterility producing precipitates such as silver reduced from a silver salt solution. The hydrogel article may be first impregnated with one chemical agent and the second chemical agent applied to one surface only so that the precipitate is formed at and just below that surface. A suitable hydrogel comprises (percentage by weight) 60% ethylene glycol monomethacrylate, 20% diethylene glycol monomethacrylate, 19% water, 0À3% ethylene glycol bismethacrylate, 0À4% ammonium persulphate and 0À3% potassium pyrosulphite.

Filed: 1975-09-15
Abstract: 1516734 Colour television RCA CORPORATION 15 Sept 1975 [28 April 1975] 37850/75 Heading H4F A record-reproducer system for playback of a record medium 11 of successive images is provided with apparatus for providing compensation for signal drop-out. The said system includes a pickup head 13 for recovering from said medium an FM signal having an instantaneous frequency representative of a composite video signal, FM detecting means 17 coupled to head 13 for deriving, from said FM signal, said composite signal having a luminance signal component, and means 100 for maintaining synchronization between said pick-up head and said record medium. In the absence of signal drop-out, detected by drop-out detector 19, the video signal is applied by a switch 21 to a video output 25 and to the input of a delay network 101. When a dropout is detected, switch 21 is moved to cut off the video signal from output 25 and network 101. At the same time, a switch 23 is moved to connect the delayed signal to output 25 and to the delay network input. On sensing of the drop-out, a one-shot multivibrator 37 is triggered. Multivibrator 37 and detector 19 are coupled to the inputs of an AND gate 55. If the drop-out lasts for longer than a predetermined number of line periods, multivibrator 37 causes switch 23 to move so that the output of network 101 is no longer applied to output 25 and the network input. At the same time gate 55 is activated to couple a grey reference signal generator 57 to output 25 by means of gate 59. This grey signal is coupled to output 25 until the end of the drop-out. The video signals may include a chrominance component and be of the NTSC type. The network 101 contains a low-pass filter 29 for the luminance component and a band-pass filter 31 for the chrominance component, the phase of the latter component being altered by 180‹ in an inverter 33. The delay signal components are added in a summing unit 35 to produce a substitute signal. The demodulated video output signal is also coupled to the means 100 for maintaining synchronization between the pickup head and the record medium, which comprises a magnetic tape. Instead of a grey reference level, a zero signal level may be used.
