Title: Leather working machine
IPC: C14B1/44
Filed: 1953-11-04
Abstract: 777,045. Buffing leather. JENKINS, E. L. B., SIMON, M. A. B., and KANE, E. A. B. Nov. 4, 1953, No. 30452/53. Class 60 [Alsa. in Group VIII] In a leather buffing machine of the typehaving a high speed rotary work cylinder and a work advancing means (normally a feed roll preferably resilient) the pinch roll that usually co-operates with the feed roll or equivalent, to feed the leather and control its passage past the work cylinder,. is replaced by a static platen arranged to provide a gap for the introduction of leather to be fed between the lower surface of the platen and the feed roll, the platen extending to a line near the bite of the feed and work rolls. As shown in Fig. 2, a leather buffing machine is made up of a buffing roll 1, a feed roll 2 having a resilient and deformable outer surface, and a feed table 8 which has an extension 9 following the curvature of roll 2. The static platen of the invention 5, consists of a blade terminating in a chamfered trailing edge 7 between the rolls 1 and 2, supported on a rod 3. The leather 10, fed between the lower surface of the static platen and the table extension 9 is forced against the feed roll by the platen 5 which is preferably curved on a radius slightly greater than that of roll 2 and centered at a point along the plane of the axes of rolls 1 and 2 to the right of roll 2, thereby forming a tapering throat between the platen 5 and the roll 2. The leather leaving the trailing edge 7 is thereby flexed as shown. The underside of the platen may be provided with diverging grooves as shown in Fig. 4 to spread the hide out on the feed roll or alternatively the platen 5 may be made up of a series of spring teeth 13 (Fig. 5) suitably divergent as shown and supported on and secured to a rod 12. As a further alternative the static platen may consist of a vertical plate mounted above the point of contact of the work and feed roll. or equivalent, the extension 9 of the table 8 in this case being extended around the feed roll 2 for almost 90 degrees.

Title: Analogue-digital converter
IPC: H03M1/00
Filed: 1964-08-04
Abstract: 1,076,811. Pulse modulation systems. SIEMENS & HALSKE A.G. Aug. 4, 1964 [July 19, 1963], No. 30469/64. Heading H4L. [Also in Division G4] In an analogue to digital converter the input voltage is converted to a pulse train of varying p.r.f. to provide a non-linear relationship between the voltage and the p.r.f. The relationship is approximated by straight line sections by means of circuitry controlled by preset positions of a counter fed by the pulse train. The analogue feeds an integrating amplifier connected to a threshold circuit, the pulse output of which passes both to a counter, which counts for a preset time to indicate the measured value, and to a variable feedback circuit, which controls the level to which the integrating capacitor is reset. This circuit varies the level in discrete steps, each step occurring after a preset number of pulses from the threshold circuit. The p.r.f. of the pulse train therefore also varies in discrete steps.

Title: Improvements in the manufacture, or treatment, of artificial silk, or like fibrous material, and apparatus for use therein
IPC: D01D10/04
Filed: 1924-12-18
Abstract: 226,808. Viscose Co., (Assignees of McKenzie, D. A.). Dec. 28, 1923, [Convention date]. Treating substances with liquids.-Relates to centrifugal apparatus for the washing &c. of cakes of artificial silk or the like In one form, the carrier comprises a number of crank arms 9, Figs. 1 and 2, mounted on a collar 13 and a baseplate 5, both of which snugly fit a perforated cylinder 11 upstanding from and rotating with a hub 25 carried by a spindle 24; the lower projecting ends 8 of the arms 0 enter recesses 7 in the hub 25, and through this connection rotary motion is transmitted to the carrier; and the upper collar 13 is located by an inwardly-tuned lug 32 carried thereby, engaging a recess in the cylinder 11. The arms 9 pass through and are guided by slots 22 in a disc 16 mounted on the base-plate 5 in such a manner that relative rotary motion between the parts is permitted; by rotation of the disc in one direction, the arms 9 are collapsed to allow the cake to be placed in position; rotation in the opposite direction, expands the carrier, causing the arms to grip the cake. On rotation of the carrier as a whole, the inertia of the disc together with the effect of centrifugal force on the arms of the carrier cause these to move outwardly, with the result that the material of the cake is put under tension; and such effect may be made more certain by providing cranked arms 28 weighted at their outer extremities, pivoted in the hub 25, and adapted to engage lugs 30 carried by the disc 16; springs cause the arms to move inwardly when the apparatus is at rest. Liquid is supplied through a central perforated stationary pipe 39, escaping as a series of jets which impinge on the perforated cylinder 11 from which the liquid is projected as a whirling. spray on to the inner face of the material; centrifugal force impels the liquid through the latter, and the liquid is finally collected in a tank in which the carriers are mounted. In another construction shown in Figs. 7 and 8, there are fewer gripping arms 9. and each carries a section 41 of a segmental screen which bears against the inner periphery of the cake of silk; the base-plate 5 and the upper collar 13 are dispensed with, and in place thereof the arms 9 are pivoted in flanges 5<a> and 12a integral with the cylinder 11, and the weighted arms 28 which pass through openings in the depending flange of the disc 16, are also pivoted in the lower flange 5<a>; a projection 54 carried by the hub 25, enters a slot 55 in the cylinder 11 for the purpose of locating the carrier on its spindle. If the inner face of the mass is unprotected, it is preferred to deliver the liquid in form of a spray which may or may not have an initial whirling motion: if, however, a perforated, reticulated, &c. screen is interposed, the liquid may be delivered in jets or in bulk, and it may even flood the interior of the mass.

Abstract: 1321283 Ultrasonic inspection devices AUTOMATION INDUSTRIES Inc 25 June 1970 [25 June 1969] 30960/70 Heading H4D A workpiece is tested by transmitting into it a burst of acoustic energy, receiving from it a corresponding burst after a delay dependent on a characteristic of the workpiece, and sampling the received burst within a time interval commencing a predetermined time after transmission of the burst of acoustic energy and substantially shorter than the duration of the burst. In the Fig. 2 embodiment the transmit transducer in a search unit is energized periodically with bursts of ultrasonic frequency pulses by gated multivibrator 22. Following each burst, after a delay determined by one-shot 30 and corresponding to the expected travel time of the ultrasonic energy through a workpiece to the receive transducer of the search unit, two brief samples are taken, a quarter-cycle of the ultrasonic frequency apart, of the received signal amplitude by means of sample-and-hold circuits 34, 36. As the workpiece is scanned, any non- uniformities therein will slightly alter the arrival time of the received ultrasonic burst and hence alter the relative amplitudes of the two samples taken, since the sample times are fixed. This alteration is displayed by applying the two samples as orthogonal deflection signals to oscilloscope 42. In the Fig. 5 embodiment one sample-andhold circuit 34 is used to sample the received ultrasonic burst amplitude and the other sample-and-hold circuit 36 is used to store the peak amplitude of a ramp voltage started after the delay provided by one-shot 30 and stopped by the next zero-crossing of the received ultrasonic burst. Circuit 36 thus provides a measure of the received burst phase. The two samples can be indicated selectively on meter 74.

Abstract: 1523142 Electrostatic precipitators M J PILAT 25 July 1975 [26 July 1974] 31140/75 Heading B2J Aerosol particles are removed from a gas stream by imposing a first charge on the particles and then dispersing a cleansing liquid into droplets and into the gas stream, the droplets having a second charge thereon, and then flowing the gases containing at least a portion of the charged aerosol particles and charged cleansing liquid droplets through an electrostatically charged bubble-forming apparatus, Fig. 17, which contains a bubble forming liquid having a third charge opposite in sign to at least one of the first two, whereby the contaminant aerosol particles are attracted to and collected by at least one of the charged liquid droplets and the charged bubble-forming liquid. The first and second charges may be of the same or opposite polarity and droplets of cleaning liquid may be collected from the emission gases by a mist collector downstream of the bubbleforming apparatus. In an electrostatic wet scrubber 'and collector assembly described, Fig. 2 for removing suspended particles from a gas stream, the dirty gas, after being cooled is passed through a charger 36 to electrostatically charge the particles and then into a spray tower 32 in which is generated from nozzles 46 a spray of a cleansing liquid which is electrostatically oppositely charged, whereby the oppositely charged spray interacts with the charged particles to precipitate them from the gas stream. The charger 36 may comprise corona discharge electrodes (76), Figs. 4 and 5 (not shown) having screw-like exterior surfaces disposed between ground plates (78). The cleansing liquid droplet charges 42 comprise liquid supply pipes 44 with spray nozzles 46 disposed in respective insulators 50 and clean dry air is supplied to each unit from ducts 80 to purge the units of unwanted deposits. The spray droplets may be electrostatically charged by direct charging from a wire inside the pipes 44, Figs. 6 and 7 (not shown), by induction charging, Fig. 8 (not shown) or by corona ionization, Figs. 9 and 10 (not shown). Potential control units 52 disposed inside the spray tower 32 may be utilized to prevent the charged droplets from migrating to the interior tower surfaces before they have captured the charged contaminant particles. Alternatively this function may be performed by disposing magnetic coil subassemblies (96, 100) Figs. 11 and 12 (not shown), either spaced axially or circumferentially about the spray tower, or by means of the particular disposition of the spray nozzles and manner of introducing the gas stream into the spray tower, Figs. 13-16 (not shown). In an arrangement for removing aerosol particles from the smoke stack gases leaving a coatfired power boiler, three such spray towers may be disposed in series, Fig. 1 (not shown), the gases being cooled in a cooling chamber before entering the scrubber units.
