Title: Gas drying apparatus
IPC: B01D53/26
Filed: 1966-09-02
Abstract: 1,099,160. Drying gases. R. P. ADAMS. Sept. 2, 1966, No. 39293/66. Heading B1L. Gases to be dried are cooled in two successive heat exchangers, and after separation of condensed water, passed to a desiccant drier stage: the dried gas then leaves apparatus via the first heat exchanger where it is reheated by entering wet gas, continuous regeneration of the desiccant being achieved by passage of a portion of the effluent dried heated gas from the first heat exchanger over the desiccant. Fig. 1 illustrates an apparatus having first and second heat exchangers 10 and 12 and desiccant drier 16. Hot compressed air enters the system at 20, and passes by tubes 40 having fins 42 to outlet 50 and thence through tubes 62 of heat exchanger 12 to cyclone separator 14. From there, the gas from which moisture has been partially removed passes by conduit 84 to desiccant drier 16 where in tubes 110 arranged in two concentric rings which fit flush into perforated end plates 96 and 100 contain a desiccant capable of regeneration by evaporation, e.g. lithium or calcium chloride. The cold dried gas is returned to heat exchanger 10 by conduit 126 where it flows over the tubes 42, its flow being directed by baffles 44, and leaves, heated by inflowing gas, at 130. A proportion of the heated effluent gas is bled by valve 140 and blower 148 to the regenerating device which comprises two spring loaded tubes 178 and 180 in alignment with the inner and outer rings of drier tubes respectively, which are continuously rotated about joint 154 and tube 156 so that heated gas passes down each drier tube in turn. A similar connection at the other end of the drier tubes is connected by links 240, 242 and splined joint 244. Wet effluent gas from the regeneration stage is returned at 270 to heat exchanger 12 for recycling.

Title: Method of and apparatus for measuring dynamic characteristics  of materials
IPC: G01N3/38
Filed: 1973-08-28
Abstract: 1431111 Measuring properties of materials TSENTRAL KONSTRUKT BJURO UNIKAL PRIBOROSTROEN 28 Aug 1973 40540/73 Heading G1A The dynamic properties of materials at very low frequencies (1Hz to 10<SP>-6</SP> Hz) are determined by oscillating a specimen at a pre-set amplitude and frequency using means comparing the motion of one end of the sample with that of a reference member driven at the desired amplitude and frequency and generating an error signal which is used to control the motion of the sample. As shown, Fig. 1, the specimen 2 is oscillated by a driving coil 9 placed in a uniform magnetic field in which is also placed a galvanometer coil 12 which is energized from a low frequency oscillator 24 via an attenuator 27 which determines the amplitude of the oscillation. Mirrors 10 and 13 are connected to the coils 9 and 12 and a photo-electric system is utilized to produce an error signal which is applied to coil 9 to cause it to follow the motion of coil 12. The real and imaginary components of the error signal are also analyzed to enable the properties of the sample 2 to be determined. The accuracy of the measurement is increased by adding two restoring signals to the error signal to form the driving current by means of attenuators 28 and 29 supplied with quadrature signals from oscillator 24. The amplitudes of the restoring signals are adjusted to be commensurate with the corresponding components of the required driving current so that the error signal produced by the photoelectric system comprises the small differences between the components of the driving current and the restoring currents. The photo-electric arrangement comprises a laser 14 and a modulator 15 the resulting beam being reflected from mirror 10 to mirror 13, back to mirror 10 and then to a critical angle prism 16. When the beam strikes the prism symmetrically it is totally reflected back towards mirror 10 this condition being achieved when both mirrors are deflected by equal amounts. Any difference in deflection of the mirrors causes a displacement of the beam which passes to one of photo-cells 17, 18 which are connected differentially to a common load 19. The resulting difference signal is applied via an A.C.amplifier 20 to a demodulator 21 and hence to a D.C. amplifier 22 the output of which is the error signal which is applied to the component analyzer 23 and also via a buffer amplifier 25 to a summing amplifier 26 where it is combined with the output of attenuators 28 and 29 to produce the driving current. The sample 2 is enclosed in a thermocryostatic chamber 1 controlled by a temperature programmer 5. Solid samples may be in the form of plates or cylinders, liquid samples may be introduced between a pair of cylinders or cones and high elastic polymers may be introduced between a pair of cylinders or moulded into cylinders.

Title: Water heater
Inventor: MILLEE AVY LEWIS
IPC: F24H1/14
Filed: 1966-09-12
Abstract: 1,119,487. Water heaters. A. L. MILLER. 12 Sept., 1966, No. 40561/66. Heading F4A. A water heater comprises a number of horizontal parallel finned water tubes 23 arranged in a plurality of passes between front and rear manifolds 21, 22, and situated above fuel burners (14, Fig. 1) within a casing (12). Baffles 24 for the flue gases are situated between and above the water tubes. From inlet pipe 43 and inlet chamber 39, the water flows in a first pass of tubes 27 across the heater to reversing chamber 34, then in a second pass of tubes 28 back to the front of the heater to chamber 45. From the latter chamber, the water flows in a third tube pass 29 to chamber 35 and then through a fourth tube pass 30 to outlet chamber 46 and outlet pipe 49. Part of the water supply to the heater by-passes the first two water passes by flowing directly from inlet chamber 39 to chamber 45 through by-pass aperture 52 which is sized to provide a suitable by-pass flow. In a modification (Fig. 3) the flow through this aperture 52 is controlled by a thermostatic valve (62) sensitive to the water temperature leaving the second water tube pass. Additionally some water may completely by-pass all the water tubes by flowing from inlet chamber 39 to outlet chamber 46 through spring loaded valve controlled openings 53, thereby maintaining the flow through the water tubes 23 independent of variations in the water supply pressure. Alternatively, a thermostatic control valve dependent on the outlet water temperature may be used to control the flow through the openings 53. Due to the use of the by-pass aperture 52, the resultant slower flow rate through the tubes of the first two passes, reduces condensation on the outside of these tubes. In a modification (not shown) only the first tube pass is so by-passed.

Abstract: 1368285 Transistor amplifying circuits MOTOROLA Inc 2 Sept 1971 [20 May 1971] 40898/71 Heading H3T An amplifier adapted to amplify an A.C. signal includes a limiter amplifier having a plurality of semi-conductor amplifier stages, including an input stage 15 an output stage 30 and a plurality of intermediate stages 21, 26-29, and direct current coupling means interconnecting the stages in cascade. The limiter amplifier has sufficient gain that the noise of the input stage 15 causes the output stage 30 to be driven between non-conduction and saturation thereby producing a rectangular wave output signal at the output stage 30. Integration means 40, 41 are coupled to the output stage 30, being responsive to the rectangular wave output signal to develop a first bias signal; feedback circuit means 51 including first and second opposite conductivity transistors 46, 55 respectively, having current sharing therebetween coupling the integration means 40, 41 to the input stage 15 and being responsive to the first bias signal to couple a second bias signal to the input stage 15 which is responsive thereto to regulate the duty cycle of the rectangular wave output signal. The arrangement is intended for use as an I.F. amplifier in a frequency-modulation receiver, operating from a single cell. The I.F. signal is applied to the base of a first transistor 12 emitter-coupled to the transistor 15. In the feedback amplifier transistors 46, 55 are cascaded emitter-followers on which the collector circuit of transistor 46 and emitter circuit of transistor 55 share a common resistor 60. The Specification explains that the arrangement is so adjusted that the duty cycle of the output rectangular wave is 50% over all the working range of the one cell supply.

Title: Bed and cylinder printing machine of the two-revolution type
IPC: B41F3/02
Filed: 1958-12-18
Abstract: 870,740. Printing machines. NEBIOLO S.p.A. Dec. 18, 1958 [Dec. 18, 1957], No. 40927/58. Class 100(2) A printing machine of the two-revolution cylinder type in which the bed is driven by a variable speed gear and the cylinder performs two revolutions during reciprocation of the bed at a speed equalling the bed speed during a part of the printing stroke of the bed, is provided with toothed sectors on a toothed wheel driving the cylinder during non-printing to cause the cylinder speed prior to the printing step to merge into the variable speed of the bed to deviate from such speed after printing, and to afford continuously variable axial spacing between the axes of the cylinder and of the toothed wheel during the lifting and lowering of the cylinder though maintaining correct meshing. As shown, an impression cylinder 5,Fig. 2, has trunnions 21, 22 mounted in bushes 23, 24 rotatably mounted in bearings 25, 26. The bushes 23, 24 are eccentric with respect to the trunnions, such that on rotation of the bushes by arms 27, Figs. 2 and 7, actuated by rods 28 rocked by.a lever 65, the cylinder 5 is lifted or lowered with respect to a bed 30. The lever 65 is rocked through a rod 63 by a lever 60 carrying a roller 59 engaging a cam track 58 in a pinion 44 on a shaft 43. During printing the cylinder 5 is driven in synchronism with the bed 30 by teeth 36 engaging racks 35 on the bed. The bed 30 is reciprocated by racks 37, Figs. 2 and 3, meshing with pinions 38 each pinion being secured to a pinion 39 engaging a rack 40 secured to the machine frame. The shaft, not shown, supporting the pinions 38, 39 is secured to a connecting rod 41 secured at its opposite end to a crank 42 on the shaft 43. The pinion 44, Fig. 7, drives a pinion 47, Figs. 2 and 7 on a shaft 48. The pinion 47 carries a concentrically mounted toothed rim 52 meshing with a toothed rim 53 keyed to the trunnion 21. A toothed sector 54 is eccentrically mounted on the pinion 47 for co-operation with a toothed sector 55 secured to the rim 53. Since the radius of the sector 54 increases in the direction of its rotation and that of the sector 55 decreases, the rotational speed of the cylinder 5 is increased gradually during the engagement of these sectors, at a rate corresponding to the acceleration of the bed 30. Sectors 56, 57 decelerate the cylinder 5, in a similar manner, upon disengagement of the toothed rims 36 from racks 37 at the end of a printing stroke. The cylinder 5 is then rotated at a uniform speed by the rims 52, 53, the cylinder 5 being maintained in raised position by engagement of the roller 59 in a constant radius portion of the cam track 58. Sheets to be printed are fed to grippers 69 (Fig. 11, not shown) on the cylinder 5 by oscillating grippers 6 (Fig. 1, not shown) while printed sheets are delivered to a pile 9 (Fig. 1, not shown) by chains 7 (Fig. 1, not shown). The chains 7 are driven by a sprocket on a shaft 51, Fig. 7, driven through pinions 50, 49, and 47 by the pinion 44.
