Title: Apparatus for generating and pumping foam
IPC: B01F25/62
Filed: 1973-02-26
Abstract: 1387975 Generating and pumping foam R E ERON 26 Feb 1973 9332/73 Heading BIC A foam generator and pump consists of a housing 12, a rotor 18 having circumferential teeth 26, an idler 32 having teeth 30 rotatably mounted on a support pin 34 that is offset with respect to the axis of the rotor 18, the pin 34 is mounted on a support plate 38 which plate also mounts a crescent-shaped partition 35. The idler, teeth 26 and partition 35 have bores therein for forming foam. Chemicals and a foam solution are introduced into the pump through conduit 51, bore 50 in the idler pin and radial bores 52. Metering is obtained by the bores 52 entering a spiral groove in the pin, which groove intermittently aligns with the grooves in the idler. The necessary fluid for carrying the foam produced is drawn through intake 45. There can be other inlets for chemicals or fluid through other bores in the pin 34 or in plate 38 into the partition 35. As the rotor 18 is rotated causing idler 32 to rotate therewith foam solution is forced through the various bores so that bubbles and thus foam is produced. A wire mesh 60 in the outlet compacts and smoothes the flow of foam discharged.

Abstract: 541,531. Converting. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., KEMP, R. J., and FALLOON, S. W. H. May 28, 1940, No. 9368. [Class 38 (ii)] [Also in Group XL] A valve circuit arranged to produce both the saw-tooth voltage for the deflecting plates, and the D.C. voltages for other elements of a television reproducer tube T comprises a blocking- oscillator valve V and an interrupting-valve V 1 . The valve V is back-coupled by the transformer T and includes a resistance-shunted condenser C3 in its grid circuit, the saw-tooth voltage on this condenser being applied to the deflecting plates of the tube T. The saw-tooth voltage or alternatively the anode voltage of the valve V is applied to the grid of the valve V 1  thereby interrupting the current through its anode inductance LI. The resulting high voltages are rectified by a rectifier D1, and give high D.C. voltages across a resistance R1, which may be tapped to provide working voltages for the anodes of the tube T. Bias for the focusing electrode F may also be provided rectifying voltages obtained by a tertiary coil L3 on the transformer T or by a secondary coil coupled to the inductance L1.

Title: Improvements in or relating to apparatus for straining suspensions of solid particles
IPC: D21D5/06
Filed: 1961-03-17
Abstract: 922,500. Rotary filters. E. WANDEL, and K. WANDEL. March 17, 1961 [March 19, 1960; Dec. 6, 1960; Jan. 31, 1961], No. 9747/61. Class 46. In an apparatus for straining solid particulate suspensions, e.g. paper pulp, a rotatable drum-shaped strainer, which is vibrated, is located between the inlet and outlet of a container for the suspension and is provided with two resiliently mounted hollow shafts one of which serves as an outlet for the strained suspension. The resilient shaft mountings are preferably annular (i.e. are substantially uniformly resilient in radial directions) but may comprise several buffer-like elements. As shown, Fig. 1, a cylindrical strainer 31 has a hollow shaft 27 mounted resiliently by a pneumatic tyre 9 in the walls of a pulp container 1, grooves 26 in the shaft bushing 25 being supplied with water to provide a lubricant cushion, a gasket 53 releasing water into the container when a predetermined pressure is exceeded. The drum is rotated by a shaft 65, and a pair of electromagnetic oscillators (not shown) are secured to a lever-like extension 57 on the bearing housing 23, preferably at an angle of 90 degrees or 120 degrees from each other to effect a substantially circular vibration. If ' n ' oscillators are used (where n>2) the angle is 360 degrees. Either the armature or solenoid, e.g. as a complete annulus if desired, of the e.m. oscillator is connected to either the container or the strainer, directly or through a flexible connecting link, the spacing between them being at least equal to the maximum amplitude of the vibrations. In one of several modifications described the resilient mounting for the hollow shaft(s) may comprise a solid rubber annulus acting directly as the bearing sleeve (i.e. bushing) for the shaft, with an interposed lubricant cushion as before. The container 1<SP>11</SP> preferably has a helical configuration, Fig. 5, so that the suspension, under pressure if desired, flows either as a single or as a divided current, along an increasingly narrow peripheral channel around the strainer drum toward a waste outlet 162, comprising a bucket wheel 172. The strainer is cleaned by a resilient scraper, e.g. of wood, 164 incorporating a suction chamber 165, and by air or water streams from a tube 173.

Title: N-vinylation of lactams
Inventor: MILLER SAMUEL AARON
IPC: C07D207/267
Filed: 1956-03-29
Abstract: Lactams containing an > NH group in the ring are N-vinylated by dissolving acetylene in a solution of an alkali metal or alkaline earth derivative of the lactam in the lactam, either alone in liquid form or in admixture with an organic liquid in which the lactam is soluble or with which it is miscible and which is inert with respect to the reactants under the reaction conditions, at a temperature below 50 DEG  C. and at a pressure not greater than 20 atmospheres gauge and thereafter heating this solution to a temperature within the range 110-200 DEG  C. at a pressure such that no gaseous phase is allowed to form during the reaction.  The solution of lactam derivative in the lactam may be made by mixing the lactam with sodium or potassium hydroxide or an alkaline earth metal oxide or hydroxide and distilling off the water formed; the alkali metals themselves and their oxides may also be used. Organic solvents which may be present include tetrahydrofuran, dioxane, acetonitrile, toluene and, less suitably, vinyl pyrrolidone.  Sodium pyrollidone tends to precipitate from its solution to some extent, especially in the presence of tetrahydrofuran, and when employed its solution should be prepared at slightly raised temperature or a dispersing agent such as aluminium stearate, should be present for optimum results. Preferably, 2 to 5 per cent of the lactam is converted into its alkali metal or alkaline earth metal derivative.  The vinylation is preferably effected continuously.  In typical examples: (1) a mixture of pyrrolidone and tetrahydrofuran in which potassium metal has been dissolved (weight proportions 50 : 25 : 1) is passed down a packed column counter-currentwise to acetylene at 15 DEG  C. and under 20 atmos. gauge pressure and the resulting acetylene saturated liquid is pumped into a stainless steel tube maintained at 155 DEG  C. and 120 atmospheres gauge; the reacted mixture flows out through a water-cooler and pressure controller into a receiver at atmospheric pressure and is distilled to recover the solvent and vinyl-pyrrolidone product; the residue comprising unchanged pyrrolidone and its potassium derivative is mixed with the recovered solvent and fresh pyrrolidone, and the above procedure is repeated; this recycling of the residues may be continued until the proportion of polymeric by-products including ethylidene dipyrrolidone becomes excessive; (6) a fine dispersion of sodium in tetrahydrofuran is added to a mixture of pyrrolidone and tetrahydrofuran containing a little aluminium stearate and oleic acid; after evolution of gas has ceased, the solution is employed under conditions similar to those of (1) to prepare vinyl pyrrolidone.  Other specified lactams for vinylation are caprolactam and 2-piperidone.  According to the Provisional Specification the vinylation is effected at 110 DEG  to 180 DEG  C.

Title: Control of the cable drum of a winch holding a free-falling ramming weight
Inventor: PFISTER ROMAN
IPC: E21B1/02
Filed: 1993-11-04
Abstract: The invention relates to a control system with which the rope (3), drawn off from a cable drum (4) by a ramming weight (5), can be braked essentially without shocks within a predetermined overrun travel while avoiding a slack rope formation and while maintaining the selected drop height during subsequent blows, the winch drum being driven with adjustable torque by a motor (12) via a slip clutch. The torque when lifting over the height of the overrun travel is set to a threshold value which is matched to the weight of the rope and the load suspension device in such a way that the latter, but not the ramming weight (5), is lifted. After the threshold value is reached, the tensile force of the rope activates a measuring device (15) before or during the lifting of the ramming weight, which measuring device (15) measures the sectional length up to the desired drop height. When the threshold value is reached, the clutch is switched from the lower torque of the overrun travel to the torque for lifting the ramming weight or to the rated torque. The clutch is switched to free running after a rope length corresponding to the drop height is wound onto the winch, and the winch brake is engaged as soon as a rope length corresponding to the drop height has run off the winch drum. <IMAGE>

Abstract: A method and apparatus for canceling both earseal and hybrid echo in a Wireless Local Loop telephone system is disclosed. The present invention operates within a subscriber station having a plurality of telephone inputs, one of which is a dedicated handset and at least one other input being a standard analog telephone. During a conference call between a far end speaker and two near end speakers, the far end speaker may hear an echo of his own voice due to an earseal echo generated by the dedicated handset and a hybrid echo generated by a 4-to-2 wire hybrid interface within the subscriber station. In accordance with the present invention, two distinct echo cancellers are used in the subscriber station to reduce the two types of echo. A first echo canceller is optimized to remove the earseal echo generated at the dedicated handset while a second echo canceller is optimized to remove the hybrid echo generated at the 4-to-2 wire hybrid. The two echo cancellers operate independently such that neither echo canceller need adapt its filter coefficients when a change in the echo channel characteristics occur, such as when a speaker hangs up or another speaker joins the conversation.

Title: Image forming device
Inventor: YASUDA KAZUO
IPC: B41J2/525
Filed: 1994-01-11
Abstract: PURPOSE:To improve the color reproducibility in a highlight area by selecting a reference wave with a color switching signal so as to deviate a recording dot latent image position thereby avoiding toner images of each of colors from being overlapped at a low density area. CONSTITUTION:The device is provided with one set of a reference wave generating means or over, a selector means and a pulse width modulation means implementing pulse width modulation to select any of reference waves with a color switching signal. Since a recording dot latent image position for each color component is deviated, toner images of each of colors are not overlapped at a low density area to make the deposition of toners of each color developed on 2nd and succeeding times onto an image medium stable thereby controlling the depositted quantity of each color toner with high accuracy. Since the deviation in each toner image is sufficiently small and cannot be recognized by a resolution of human eyes, the color reproducibility is enhanced to the utmost. On the other hand, since the overlapping of toner images is increased as the density increases, the color reproducibility at a highlight area is secured in an excellent way.
