Abstract: 1,116,235. Crimping yarns. JOSEPH BANCROFT & SONS CO. 14 Oct., 1965 [26 Oct., 1964], No. 43659/65. Heading D1F, In a stuffer-box crimping apparatus, a core 21 of crimped yarn emerging from the heated compression chamber is immediately advanced through, and is cooled within, a continuation of the chamber in registration therewith formed by a cage consisting of a series of periperically spaced members or rods 19 between which sets of pivoted fingers 23 extend to engage the core on opposite sides and apply adjustable compacting and retarding pressure thereto. Treating liquid e.g. dye, may be supplied through axial passages in pivot shafts 25 thence to internal passages in the fingers 23 and discharge into the crimped material through openings 37 and additionally through nozzles 41 terminating in felt pads 43. A feeler 60 resting lightly on the top of .the core 21 is carried by the control arm 61 of a micro-switch whereby the feed of yarn into the chamber is controlled to maintain the withdrawal point of the crimped yarn at a predetermined level. A traversing guide feeds the yarn so that it is packed uniformly into the crimping chamber throughout the whole elongate cross-section thereof.

In a dough dividing machine dough is delivered from a hopper 2 by contra-rotating delivery rollers 10, 11 and is divided and delivered for ejection through an outlet 30, on to a conveyer, by cutters 14, 15 which are mounted for reciprocating displacement in a diametrical direction through hollow cylindrical guide members 12, 13 which contra rotate cyclically through an angle α. The dough passage through the machine is enclosed by end walls, by the interior surfaces of dough wipers which engage at surfaces 22, 23 and 24, 25 respectively with the delivery rollers 10, 11 and guide members 12, 13, and the interior surfaces of dough wipers which engage at surfaces 26, 27 with the guide members 12, 13. In the uppermost position of the guide members 12, 13 and cutters 14, 15, the latter are in their retracted open position, with the outlet 30 closed by a horizontally displaceable knife 32. The cutters are closed, either into toothed or overlapping engagement, as guide members 12, 13 begin to rotate downwardly so that dough is compressed in the space thereby enclosed until, at a predetermined position, the knife 32 is opened to permit discharge through outlet 30 upon continued rotation of the guide members 12, 13, with the cutters 14, 15 remaining closed to their lowermost position. In this position the knife 32 closes and the cutters 14, 15 are retracted and the guide members 12, 13 are then rotated to raise the cutters 14, 15 to their uppermost position. The uppermost position of the guide members 12, 13 is adjustable to vary the weight of divided dough. A plurality of dough division may simultaneously be discharged through a multi-orifice outlet provided with upwardly extending partition walls thereabove.

Title: Method and device for washing constituents from gases
IPC: B01D47/10
Filed: 1977-10-25
Abstract: The venturi tube (20) has a convergent part (22), a diffuser part (24) and a throat (26). At an axial distance from each other, rings of nozzles (28, 30, 32) open out radially inwards. The cross-sections of the nozzles near to the throat are conventionally smaller and those of the more remote nozzles larger so that the flow of the scrubbing agent corresponds in each case to the corresponding diffuser cross-section (36, 38). The nozzles (28, 30, 32) are optionally fed with scrubbing liquid, that is the nozzles (30, 28) situated nearer to the throat (26) in the case of a relatively small gas stream and the nozzles (30, 32) more remote from the throat (26) in the case of a relatively large gas stream. In this way the scrubbing performance is matched well to the gas flowing through. <IMAGE>

Title: Pulp treating machine
Inventor: HONEYMAN ROBERT BLAKELEY
IPC: B02C7/14
Filed: 1961-12-12
Abstract: 930,174. Pulp refining machines. MORDERN MACHINES CO. Dec. 12, 1961, No. 44430/61. Class 59. A pulp treating machine comprises a driven shaft 11 carrying a rotating element 17 cooperating with a substantially coaxial non- rotating element 19, attrition surfaces 17A, 19A on the elements, and a pair of bearing assemblies 13, 14 supporting the shaft of which the assembly 13 nearest the rotating element is a spherical-type thrust bearing providing for a slight tilting of the shaft about the centre 0 of the bearing. The attrition surfaces have their inner and outer peripheries arranged so that all points on them are equidistant from the centre 0 of the spherical bearing and the surfaces provide a constant gap therebetween between the inner and outer peripheries, whereby a slight deviation of the axis of the rotating element with respect to its alignment with the axis of the non-rotating element has only a minimum effect on the gap between the surfaces. The attrition surfaces, which may be spherical or conical, consist of bars mounted by bolts 18 on the elements 17, 19, element 17 being secured by a nut 12 to the shaft 18 which is rotatable in the spherical bearing 13 and bearing 14 which permits small radial movements of the shaft. The rotating element 17 is formed with vanes 27 which act to pump material, fed under pressure or by gravity through a channel 26 in the direction of the arrows between the attrition surfaces to an outlet channel 22, a lower channel 24 with a cover 25 being provided to trap foreign particles. The non-rotating element is axially movable to vary the gap between the attrition surfaces by rotation of a handle 44 connected to shafts 38, 42, 43 having worms 39 engaging wheels 34 which act as nuts on bolts 30 secured to the non-rotating element, the bolts having guides 29 running in channels 23; alternatively, the shaft 38 may be adapted to be driven by a motor. During operation, slight tilting of the axis of the shaft 18 about the centre 0 has no effect on the gap between the attrition surfaces when the surfaces are spherical and only a minimum effect when the surfaces are conical. In a further embodiment, the vanes 27 are omitted from the rotating element and the material to be treated is fed through the channel 22 and is discharged through the channel 24.

Abstract: 1298978 Analyzing gases photo-electrically AEROCHEM RESEARCH LABORATORIES Inc 22 Sept 1970 45130/70 Heading G1A The concentration of a particular gas in a gas mixture is measured by passing the gas mixture at a given flow-rate through a reaction chamber 2 maintained at a pressure of 0À1 to 1À0 torr, mixing with the mixture a reactant gas flowing at a predetermined rate, and photo-electrically detecting the intensity of radiation given off as a result of the chemiluminescent reaction between the gas to be measured in the mixture and the activated species of gas. As shown, a photo-multiplier which may be cooled to -20 to -60C. is used to detect emitted light, but a germanium diode is used if infrared radiation is emitted. The radiation is chopped, 18, e.g. by a vibrating slit, and a phasesensitive detector 26 provides an output to a recorder 24. Alternatively, a pulse counting method may be used to deal with the detector output. A filter or mono-chromator 16 is used to isolate the spectral region of interest. The apparatus is calibrated by first using pure air as the gas mixture to obtain a zero reading, then flowing through the chamber air containing various known amounts of the particular contaminant to establish a scale.

Abstract: 1,023,671. Piezo-electric crystals. TOYO TSUSHINKI KABUSHIKI KAISHA. Dec. 6, 1962 [Dec. 27,1961], No. 46134/62. Heading H1E A lattice filter is realized by means of a crystal plate having divided electrodes and vibrating in two fundamental thickness-shear modes. The plate is an AT or BT quartz cut, the major faces of such a plate being in the XZ plane. It is stated in the Specification that one fundamental thickness-shear mode exhibits a displacement distribution with one sine wave in the X direction, one cosine wave in the Y a  direction and zero displacement in the Z a  direction. Such a mode may be designated (1.1.0). Two further so-called inharmonic modes can be expressed as (2.1.0) and (1.1.1), these having similar sine and cosine distributions. In the filter of the invention, the fundamental mode and one of the inharmonic modes are excited in the plate. The plates of Figs, 2A, 2B utilize the (1.1.0) and (2.1.0) modes and have electrodes divided in the Z a  direction so that transmission is in the X direction. By minimizing the Z a  dimension of the plate as in Fig. 2B, the (1.1.1) mode can be suppressed; in the plate of Fig. 2A this mode is present but does not affect the electrical input or output. In the circular plates of Figs. 2D, 2E suppression of unwanted modes is achieved by means of slits 20. By dividing the electrodes in the X direction (so that transmission is in the Z a direction) a plate utilizing the (1.1.0) and (1.1.1) modes may be realized. In both types of plates the two modes of vibration have an antiphase relationship and this property is utilized in the design of a bandpass filter. The Specification describes in detail the equivalent lattice network for a plate vibrating in each of the modes discussed and it is shown how the equivalent reactances are related to electrode distribution and crystal size. The crystal is dimensioned so that the resonance frequencies of the fundamental and the inharmonic modes are adjacent, the difference being one-half of the band-width. A three-terminal filter may be realized by connecting one pair of divided electrodes to a common terminal as shown in Fig. 4A. Filters may be connected in cascade and capacitances connected across input and output terminals to provide attenuation poles.

The softened zone is drawn downwards by members 6 and 7 (Fig. 3, not shown), forming a construction 8 in the tube and locally decreasing the wall thickness.  The lower end of the tube is then held by a centring ring 9 (Fig. 4) and a rotary moulding roller 10 pressed laterally into the constructed portion to reduce its diameter, forming the neck portion 11.  When the neck portion is no longer plastic, heat is applied to the body portion 12 of the bulb which is inserted in a hollow split mould 13, 14 (Fig. 6) and widened by differential pressure, either suction or blowing. The mould 13, 14 is removed and the neck 11, which is still hot from the shaping operation, is severed by making a circular scratch by means of a rotary cutting wheel 15 (Fig. 7) and producing an annular zone 19 of stress by means of compressed air at 18, which causes fracture of the neck along the scratch. The stresses in the neck portion 11 produced by the rolling are removed by the heating of the body portion 12. The method of the invention may be carried out in the machine described and claimed in Specification 1,010,966.
