Abstract: 484,218. Valve amplifying circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd., and PERCIVAL, W. S. Nov. 9, 1936, No. 30427. Addition to 448,421. [Class 40 (v)] In a valve amplifier circuit of the cathodefollower type as described in the parent Specification, the cathode of the valve is isolated from the output circuit in respect of D.C. or low frequency voltages by feeding the latter through a path to the output which byepasses the valve. Thus in the Figure, D.C. and low-frequency voltages are fed directly to the output 8 over resistance 5, while the higher frequencies are applied over condensers 4 and 6. Resistances 5 and 7 are adjusted to compensate for attenuation of the higher frequencies due to the amplification of valve 1 being less than unity. The valve 1 may be a screen-grid valve and the circuit can be usedas a low-frequency attenuating circuit; condenser 6 and upper terminal 8 are then connected to an adjustable tapping on resistance 7.

IPC: G01G23/365
Filed: 1963-08-02
Abstract: 1,060,831. Potentiometric measuring arrangements. GIRLING Ltd. Nov. 2, 1964 [Aug. 2, 1963], No.30688/63. Heading G1U. In a voltage measuring apparatus of the kind in which the unknown signal and a second reference signal are applied as inputs to a comparing circuit, the output from the comparing circuit operates arrangements for actuating a first or a second clutch according to whether the unknown signal is greater or smaller than the reference signal, and the actuation of the appropriate clutch causes a motor to operate a reference signal varying arrangement until the inputs to the comparing circuit are equal. The motor is operated continuously in use. In an arrangement for measuring a voltage output from a weighbridge 11 energized from an A.C. supply, which also supplies the transformers 14 and 15, one side of the weighbridge output is connected to the mid point of the winding of a potentiometer 24 (taken at the junction of resistors 21,22) through a resistor 19 in parallel with the transformer secondary 16 and the other side is connected to the difference amplifier 27. The other input to this amplifier is taken from the potentiometer wiper 20. The amplifier 27 produces a positive or negative output signal, according to whichever input signal is the larger, to operate either relay 28 or 29. If the amplifier output falls below a predetermined value, a relay 31 is operated. The relays 28 and 29 control as appropriate the supplies to electromagnetic clutches 36, 37 in the output shafts of the motor 38, to drive the wiper of the potentiometer 24 through the gearing 39. As balance is approached the relay 31 is actuated to alter the supply to the motor 38 so that it runs more slowly. At balance all relays are deenergized so that the clutches 36, 37 are disengaged and a brake 40 is applied. The output indication means are associated with the gearing 39. The variable resistors 25 and 18 in the supply to the potentiometer 24 from the transformer 14 and in the weighbridge output circuit enable adjustments for calibration and unladen container weights to be made. The advantage of this system is that sensitivity is increased by eliminating the need to overcome the starting torque of the motor each time the reference potential is to be adjusted.

Title: Improvements in or relating to a process of removing pollute from sewage
IPC: B01D17/02
Filed: 1948-11-26
Abstract: 654,917. Purification of sewage. INFILCO, Inc. Nov. 26, 1948, Nos. 30712 and 30713. Convention dates, Dec. 31, 1947 and July 3, 1948. [Class 111] Pollute is removed from sewage by employing an insoluble and chemically inert pollute-philic material, introducing the sewage to be treated and the philic material into a thick suspension of such philic material in sewage undergoing treatment, agitating the suspension to mix the entering sewage and philic material and to hold the particles in said suspension against sedimentation, retaining the sewage for a period of time in the suspension, withdrawing treated liquid from the suspension and withdrawing pollutecontaminated particles from the suspension to waste. The pollute-philic material may be calcium carbonate, e.g. the sludge from a water softening plant, humus from a sewage sludge digester, ground limestone containing maybe magnesium compounds, diatomaceous earth, fuller's earth, bauxite and some of the clays, and the particle-size of these materials should be of the order of the particle size of the sludge from a water softening plant. As shown in the flow diagram, sewage to be treated is introduced into a mixing and reaction zone wherein is maintained a suspension of the philic material in sewage and is stirred as by mechanical stirrers to mix the entering sewage and the suspension, to hold the suspension against sedimentation and to circulate it through the mixing zone. The treated sewage from this zone escapes in clarified form from a horizontal interface and flows over a launder. A quantity of fresh solid particles of the philic material is continuously added to the suspension in the mixing zone, preferably about equal to the solid content in the sewage entering the zone or in amounts about the same as the biochemical oxygen demand of the entering sewage. Contaminated particles of the philic material are withdrawn from the concentrator. Raw sewage may be treated without preliminary separation of the solid matter or grit, the suspension in the mixing zone being impelled so as to retain the philic material in suspension but so as to allow the sedimentation of grit. The pollute philic material is retained and accumulated in the suspension to produce a concentration of the philic material preferably many times greater per unit-volume of sewage being treated than the quantity of the material added per unit volume of incoming sewage. The withdrawn sludge may be carbonised and utilised as the pollute philic treating material.

Title: Improvements in or relating to pulleys for t-section endless bands
IPC: B62D55/14
Filed: 1924-12-24
Abstract: 226,826. Kegresse, A. Dec. 26, 1923, [Convention date]. Pulleys.-In automatic clip pulleys for use with endless T-belts, such as are used for example, on endless-track vehicles, the belt is gripped between pulley-halves by the action of interengaging inclined surfaces so that the grip varies with the load, the dust, mud, snow, &c. through which the belt moves being allowed free access to the inclined surfaces so as to affect their coefficient of friction, the grip varying inversely as the coefficient of friction. In the form shown in Fig. 1, the driving-shaft 1 is keyed to a sleeve 4 to which is secured a drum 5 carrying inclined surfaces 6 engaging with similar surfaces 7 on one pulley-half 8, between which and the second pulley-half 11 is arranged the belt 2. The half 11 is secured rigidly and the half 8 by a flexible plate 9 to a sleeve 10 loose on the sleeve 4. Interaction between the surfaces 6, 7 presses the half 8 laterally into contact with the belt with a force varying directly with the load. Apertures 12, 13 in the parts 8, 5 allow free access of mud &c. to the surfaces 6, 7, the grip-producing action of the surfaces varying inversely with the coefficient of friction between them. Fig. 3 shows a modification in which the pulley-halves 16 slide axially on but turn with bolts 14 securing together drums 5, 5<1> bolted to the sleeve 4 turning with the shaft 1. The inclined surfaces 7 are secured to the halves 16 and the interengaging surfaces 6 are secured to loose rims 15 supporting the belt, thrust washers 18 being arranged between the surfaces 6 and flanges on the drums 5, 5<1>. Apertures allow access to the surfaces 6, 7. Slip of the rims produces axial movement of the halves 16. In a further modification, the surfaces 6 are secured to the drums 5 and the rims 15 are integral with the halves 16, which must then be capable of both axial and turning movement on the bolts 14. Specification 199,373 is referred to.

Title: Improvements in and relating to television
IPC: H04N3/08
Filed: 1936-11-13
Abstract: 467,227. Television. BAILEY, W. C., and ASHDOWN, E. S. Nov. 13, 1936, No. 31035. [Class 40 (iii)] Relates to scanning apparatus for receivers, of the kind in which two mirror drums rotating at different speeds about relatively inclined axes co-operate to cause a modulated beam to scan a viewing screen. According to the invention, a mirror drum 2 carrying a relatively large number of mirrors, and a polysided mirror 16 having relatively few reflecting surfaces are so geared to a motor 15 synchronized with the transmitter that the drum 2 (for line scanning) is driven at a high speed and the member 16 (for framing) at a reduced speed, each mirror 3 on the drum 2 being so mounted and controlled that it is automatically rocked as it passes into the modulated beam from a lamp 1, so that it causes a rapid scanning movement of the reflected beam which is again reflected by a fixed mirror 22 on to a slowly moving mirror of the member 16, which finally reflects the light on to the screen 17. The drum 2 may be formed as a toothed wheel 4, Fig. 3, over which is stretched a rubber band 5 carrying the mirrors 3 so that they project laterally. An idler toothed wheel 6 engages with the wheel 4, its teeth causing the mirrors to rock in turn by pressure on the band 5. In a modification, the mirrors are formed on rectangular blocks mounted between teeth on a wheel by cranked pins passing through rubber sleeves the pins being adapted to engage in turn with a fixed cam.

IPC: C08G63/127
Abstract: 310,854. British Thomson-Houston Co., Ltd., (Assignees of Adams, L. V.). May 1, 1928, [Convention date]. Ester condensation products.-The production of resins from polyhydric alcohols such as glycerine, glycol, mannitol, or erythritol and polybasic acids such as phthalic, succinic, cinnamic, diphenic, or naphthalic acid is effected in the presence of an organic compound of a polyvalent metal, such as a soap or resinate. In the examples, (1) phthalic or succinic anhydride is reacted with glycerine in presence of cobalt linoleate, or lead oleate; (2) phthalic anhydride and glycerine are reacted in presence of aluminium stearate; (3) phthalic anhydride or diphenic acid is reacted with glycerine in presence of ferric or bismuth or other lactate; (4) glycerine is treated with metallic calcium and the product is treated with phthalic anhydride to form calcium phthalate; after a few days the calcium is removed, and phthalic anhydride or another polybasic acid is added. Other metal compounds mentioned as suitable for use in the reaction are zinc and manganese resinates, lead glyceroxide (a compound of lead oxide, an oxide of an alkaline earth metal such as lime, and glycerine), and lead tannate. Specification 236,591 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes another example in which phthalic anhydride and glycerine are heated until the anhydride fuses, and metallic calcium is added, the calcium being removed when the resin is formed. Alternatively, glycerine which has been treated with an alkaline earth metal may be reacted with phthalic anhydride in presence of such metal. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 306,924.

Title: Improvements in or relating to apparatus for sorting, counting and packing coins
IPC: G07D9/06
Filed: 1929-10-15
Abstract: 347,150. Packing coins. CHIGER, S., 9, Wilhelmstrasse, Berlin. Oct. 15, 1929, No. 31270. Convention date, June 13. Void [Published under Sect. 91 of the Acts]. [Class 94 (i).] In an apparatus for counting and packing coins adjustment of the apparatus for a particular kind of coin determines the number of coins which have to be counted and packed. A device forming the subject-matter of Specification 341,855 by means of which packets of coins or various denominations are delivered to the appropriate collecting chambers is also described. A crank 5, Figs. 1 and 2, is rotated until a pin 6 can engage one of a number of holes 3, each of which is marked for a coin of a particular value. A toothed wheel 9 is thus rotated and operates a rack 10 so as to move a table 12 and a container 48 to a distance from the sealing device (not shown) and a feed shoot 51, corresponding to the number of coins which have to be counted and fed to the container. A cam 18 is simultaneously rotated, so that a rack 19, moving in the direction of the arrow Fig. 2, rotates a spindle 22 and winds a spring 25 ; while two toothed segments 29, 28 are also rotated, the latter so that a number of teeth corresponding to the adjustment of the crank 5 pass a cam 43. Each coin before passing to a container through the hole 50 and shoot 51, rotates a counting wheel 42 and the cam 43 through a distance equal to one tooth, so that after the passage of sufficient coins the cam 43 moves the segment 28, and therefore the segment 29 through one tooth. When a projecting tooth 30 comes in contact with a lever 31, the spring 25 is released and the parts return to their former positions. In order to allow time for this return movement to take place a pin 34 on the lever 31 engages in a recess in a pawl 35 until the lever 31 coming into contact with a coupling 47 causes a spindle 46 and a plate 39 to rotate so that a pin 40 releases the pawl 35 ; under the influence of the spring 31a the lever 31 then returns to engage the segment 29. A plate 13 is then rotated to bring a fresh container beneath the shoot 51.
