Title: A Printing Press having a Rotary Drum for Delivering Freshly Printed Sheets without Set-off
IPC: B41F22/00
Filed: 1968-03-06
Abstract: 1,191,221. Printing-apparatus. ROLAND OFFSETMASCHINENFABRIK FABER & SCHLEICHER A.G. 6 March, 1968 [16 March, 1967], No. 11003/68. Heading B6C. A rotary drum adapted to deliver freshly printed sheets without set-off comprises a peripheral wall 46 made at least in part of air permeable material and a plurality of chambers 42, 43 to which air is supplied under pressure through feed ducts 22, 23, the air passing through the wall 46 forming an air cushion adapted to maintain the freshly printed sheets out of contact with the wall. The wall 46 may be of fabric, of sintered or porous plastics material, or of porous sheet metal, and may be covered by a porous plastics member 57. Axially extending ribs separate the drum into chambers and slides 44, 45 control the air flow into the chambers. The effective areas for the escape of air may be varied by turning cover rings 28, 29 with respect to housings 14, 15 within the limits of slots (11), Fig. 3 (not shown). A weight 60 balances the weight of the chambers on the drum.

Title: Circuit for a colour television receiver including a chrominance signal amplifier stage
IPC: H04N9/68
Filed: 1971-04-23
Abstract: 1351352 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 April 1971 [28 April 1970] 11067/71 Heading H4F A circuit for processing received colour television signals for application to a display tube 19 includes a chrominance amplifier stage 51 to which are supplied signals from contrast and saturation adjusting circuits 29, 97 respectively. A pulse is supplied to the stage 51 at terminal 89 during each line blanking period to produce an output at terminal 53 which is independent of the settings of circuits 29, 97. This pulse turns transistor 87 on and transistors 91 and 93 off so that the whole of the output of transistor 75 appears at terminal 53. In the absence of a pulse at input terminal 89, transistor 87 is off and transistors 91, 93, 79, 83 on, transistors 83 and 93 diverting portions of the output of transistor 75 away from terminal 53 depending on the inputs at terminals 85 and 95. A generator 35 produces the pulses for application to terminal 89, deflection currents for tube 19, and a beam current limiting voltage for application via combiner 25 to terminal 85 with the signal from circuit 29. The generator 35 also produces gating pulses to gate throughput from terminal 53 to a rectifier circuit 69, the D.C. signal from which is used to control an amplifier 45 to produce automatic gain control. The output from terminal 53 is applied to a demodulator 57 and the luminance signal is passed to tube 19 via an amplifier 13. In an alternative embodiment (Fig. 2, not shown) transistor 93 is omitted, the base of transistor 87 is connected to a fixed voltage source, and the pulses from generator 35 applied in Fig. 1 to terminal 89 are now supplied, along with the signal from circuit 97 to the base of transistor 83, the chrominance output being taken from the collector of transistor 83 which has a load resistor connected between it and a reference voltage. Combiner 25 is now connected to the base of transistor 91 and circuit 69 is connected directly to terminal 53 and hence the collectors of transistors 79 and 87. In a further embodiment transistors 91 and 93 and circuit 97 of Fig. 1, are omitted.

Title: Servo systems
IPC: G05D3/14
Filed: 1962-03-23
Abstract: 994,999. Electric servo systems. SPERRY RAND CORPORATION. March 23, 1962 [April 28, 1961], No. 11165/62. Heading G1N. A servo-loop is self-adjusting to varying load conditions to maintain a constant stability by automatically adjusting the damping ratio, based on the principle that if the system is subjected to a forcing test signal whose frequency is linearlyrelated to the natural frequency of the system, then the phase shift between the output and input signal is proportional to the system damping ratio. The frequency ratio is proportional to the attenuation of the test signal, which is therefore maintained constant to establish a constant frequency ratio, and the subsequent phase shift between input and output signal is then also maintained at a constant value to stablize the damping ratio. As shown (Fig. 1), a servo system obtains its input signal # i  from a generator 11 to energize s motor 13 driving a load 15. A positional output signal # o  obtained at 16 and a rate signal # derived from tachogenerator 21 are combined with the input signal # i  in summation devices 20, 22 to produce the control signal #. A forcing test signal from an oscillator 23, whose frequency is to be maintained at e.g. three times the undamped natural frequency of the servo system, is added to the input signal # i  in summation device 24. The test frequency output signal is obtained at 16 and amplified at 25 by a preset amount which brings it back to the original level when the ratio of the test frequency to the natural frequency is constant. Any difference is this frequency produces a difference in level between the amplifier 25 and oscillator 23 which is measured by filters 26, 27 rectifiers 30, 31 and summation device 32 to produce a voltage which controls the frequency of oscillator 23 to restore the desired constantfrequency ratio. The phase shift between the outputs of amplifier 25 and oscillator 23 is determined at 33 and converted to a proportional D. C. voltage which is compared with a preset voltage at 34 representing a desired damping ratio, any difference being used to energize a motor 37 which adjusts at 38 the proportion of rate signal # fed back in the main servo-loop, thereby maintaining the damping ratio at a constant value. In another embodiment (Fig. 3) where the difference between the input signal # i  from 11 and the output signal # o  from 16 is integrated at 41 before the rate signal # from 21 is added to it, the means for maintaining the damping ratio constant by measuring the phase difference between the input test signal and the output test signal, and comparing this with a preset phase signal at 34 to produce a control voltage for rate potentiometer 38, is augmented by a signal derived from the phase difference between the integrated # i -# o  signal obtained from filter 44 and the test output signal obtained from filter 26. The two phase-difference signals are fed to a computer 47 which determines the desired amount of rate feedback and position feedback required for optimum stability.

Title: Improved method of high vacuum distillation
IPC: B01D3/10
Filed: 1937-04-20
Abstract: In the distillation of organic substances, particularly vitamins, sterols and hormones, under a high vacuum to obtain a plurality of fractions, a carrier liquid (or liquids) is added capable of yielding distillate fractions equal in number to the fractions required from the distilland and of which one distils contemporaneously with each of the desired fractions, from which it must be readily separable by physical or chemical means.  If desired, the number of carrier liquid fractions may be increased to provide intermediate flushing liquids. Examples are (1) the distillation of sterol-containing oils to obtain cholestane and stigmasterol, using as carrier liquid a mixture of tripalmitin and tricaproin or dicaproin monopalmitin; (2) the separation of free vitamin D from vitamin A esters by distillation with monocaproin dipalmitin and triolein; (3) the separation of benzpyrene from cholesteryl butyrate by molecular distillation, with oleic acid and triolein as carrier liquids; and (4) separation of indigo from dibromindigo, using dicaproin monopalmitin and triolein as carrier liquids.
