Title: Improvements in and relating to garment or laundry pressing machines
IPC: D06F71/34
Filed: 1948-04-16
Abstract: 647,600. Ironing presses. PROSPERITY CO., Inc. April 16, 1948, No. 10602. Convention date, May 9, 1947. [Class 138 (ii)] In a laundry press comprising upper and lower pressing members 1, 2, at least one having an opening and closing movement, the upper member 1 is heated and is enclosed by a hood 9 spaced therefrom and providing a chamber 10 open at the pressing face side of the member 1, the lower member 2 is formed with a perforated top-plate 2a and a chamber 15 below the top-plate, and means are provided for creating a suction effect in the hood 9 and chamber 15. Thus heated air from the pressing face 12 of the upper member 1 is drawn into the hood 9 through an inlet 11 and also, when the press is open, any rising currents of air from the lower member. The vacuum also draws air currents down through the padding of the lower member 2 and, in'addition, creates an inflow of air through the edge portions of a cover cloth 20 and through spring padding 16. This air is heated by a marginal heating chamber 22 to prevent condensation within the pad. The spring padding 16 is covered by a wire screen 17 on which is superimposed a layer 18 of steel wool, then a layer 19 of flannel or fibre glass, and the whole covered by the cover 20 of cotton or nylon. Steam is supplied to the marginal heating chamber 22 through a pipe 25 and to the upper member 1 through a pipe 23. Vacuum is applied to the hood 9 by an exhauster 27 through a pipe 32, swivel coupling 31, pipe 30 and a header (not shown) communicating with the chamber 10 at two points. The bore of the header increases in diameter from the end attached to the pipe 30 to the other end to even out the suction effect. Chamber 15 is connected to the exhauster by a header opening to the chamber 15 at two points. Specification 626,514 is referred to.

Title: Halftone Image Generator System
IPC: H04N1/405
Filed: 1967-03-08
Abstract: 1,181,151. Copying by scanning. RCA CORPORATION. 8 March, 1967 [21 March, 1966], No. 11005/67. Heading H4F. An original continuous tone picture 18, Fig. 1, is scanned photo-electrically by scanner 20 and the resulting picture signal converted to binary digit form by processor 22 and stored in a computer 12. In response to a read/write control circuit 74, the signals are subsequently released from the computer store and converted in a digital - to - analogue converter 76 back to analogue form, Fig. 3a, for use in controlling a cathode-ray tube 16. The tube is caused to produce a half-tone picture, Fig. 2, formed of variable area dots in response to the signal. The tube beam is scanned in a conventional line raster (or randomly) in step-by-step movement with blanking during movements so as to form a pattern of dots. At each dot position the beam is further deflected orthogonally by 90 degree-phase-displaced oscillations, of which Fig. 3d shows one, the oscillations being amplitude modulated by a signal as shown in Fig. 3c, whereby the beam executes a spiral scan, Fig. 4. The signal, Fig. 3a, which varies in amplitude between successive dot periods, is converted to a duration modulated, constant amplitude pulse train, Fig. 3b, which is then applied to unblank the tube beam. The reproduced picture thus comprises dots each formed of a spiral, the duration, and hence size, of which varies in accordance with the original continuous tone information. Alternate line scans are displaced slightly so as to produce a 45 degree dot pattern as shown in Fig. 2. A clock source 26 times the system operation by synchronizing a generator 21 of dot sync signals, line sync signals and blanking signals. Line (horizontal) scanning of the cathode-ray tube is controlled by a counter 36 responsive to the dot sync signals, whilst vertical scanning is controlled by a counter 38 responsive to the line sync signals. Preset counts may be set into the counters initially to position the reproduced picture. A bi-stable trigger circuit 50 triggered by line sync signals causes the displacement of alternate line scans as shown in Fig. 2. The 90 degree-phase-displaced oscillations to produce the spiral scans are provided by an oscillator 70 which provides a first output directly and a second output via a 90 degree phase shifter 54. The two outputs are modulated in balanced modulators 52, 56 by a signal, Fig. 3c, which is derived by an integrator 60 which is reset during the blanking between dots. The duration modulated signal, Fig. 2b, is produced by a bi-stable trigger circuit 80 which is triggered by the dot sync signal, and reset by an integrator 78 operating a switch 85 when it reaches the level of the signal, Fig. 3a, as determined by a comparator 82. The cathoderay tube may produce a light display which is photographed or the electron beam may make a recording directly. The production of a half-tone image by means of an imaging device controlled to produce variable area dots formed by spiral scanning forms the subject of Specification 1,181,153.

Title: Improvements in or relating to thermionic valve circuits having a constant output
IPC: H03G11/00
Filed: 1940-07-06
Abstract: 542,366. Changing wave shapes. HADFIELD, B. M. July 6, 1940, No. 11337. [Class 38 (ii)]  [Also in Group XL] A thermionic valve circuit is adapted to suppress a portion of the input wave form to give an output waveform of trapezoidal shape in which for varying amplitudes of the input waveform, the amplitude and mean angular displacement of the output trapezoidal waveform are constant. The mean angular displacement is the angular distance of the mid-point of the sloping sides of the trapezium from the mid-point of the level top, and it is demonstrated that if the mean angular distance is u the output contains no nth harmonic. This is effected by the circuit of Fig. 3 in which an alternating input is applied by a transformer T 1  through supply resistances r to the grids of push-pull connected pentodes V 1 , V 2 , the cathodes of which are connected by a potentiometer P the tapping point of which is connected to the biasing resistance Rc. The gridcathode circuits contains the network C, R, having a time constant which is large with respect to the periodicity of the input. The input is of such magnitude that the peak values cause grid current to flow, also when steady state conditions are established, a steady voltage Vc, Fig. 4, appears on C. The rectified half wave produces an output such as is shown in heavy line, the shaded area being suppressed in charging the condenser C which also maintains the minimum current value. Since the output is coupled in push-pull the output is alternating of which Fig. 4 shows a positive half cycle. The mean angular displacement is shown to depend on the ratio r/R and so any undesired odd harmonic can be eliminated. Part of the voltage on Rc is applied to the suppressor grid to reduce the increase of anode current on the occurrence of grid current. The application of the invention to an input of two mixed frequencies is also described.
