Title: Process of making fibrous webs
IPC: D21F11/00
Filed: 1963-08-07
Abstract: Paper is made from a suspension of fibres containing a chemical agent that can increase the viscosity of water and is substantially non-substantive towards the fibres.  The agent is hydroxyethylcellulose or a mixture thereof with one or more of sodium, potassium or ammonium polyacrylate or a microbiological polysaccharide.  It is used in an amount sufficient to increase the viscosity of the water alone to 20 to 500 centipoise at 20 DEG C. Substantially the whole of it remains in the white water, which is recycled with little or no further addition of the agent.  The fibres may be derived from softwoods, hardwoods, straws or bagasse, or may be of polyacrylonitrile, rayon, polyester or nylon.  The agent may be incorporated before or after beating, but before the suspension is directed to the paper-machine wire. The slurry may also contain wet-strength resins, rosin size, alum, starches or colorants, but not such as would gel the chemical agent.

Title: Improvements in machines for applying coatings of granular, shredded or like material to bakers' and confectioners' goods
IPC: A23G3/20
Filed: 1929-10-18
Abstract: 341,128. Coating bakers' and confectioners' goods. SALERNO, F. G., 1029, West Harrison Street, Chicago, U.S.A. Oct. 18, 1929, No. 31753. [Class 28 (i).] A machine for applying a top and/or bottom coating of granular, shredded or like dry material to wafers or cakes which have just previously been coated with icing, jelly, chocolate or the like, comprises a pervious conveyer for carrying the goods through a falling stream of the material, and means for collecting surplus material, which falls through the conveyer, and applying it to the undersides of the goods. As shown in Fig. 4, the shredded material is contained in a hopper 12 and is withdrawn by a belt 14 which passes over a plate 13 at the bottom of the hopper. The exit gap, and therefore the amount of material withdrawn is varied by the screw 18, the hopper being hinged to permit this adjustment. A stirrer 19 is provided in the hopper, and the hopper, stirrer, and feed belt and plate 13 are removable as a unit for cleaning &c. The material falls on a screen 22, mounted on rocking arms, and from thence on to the goods or the belt B. Surplus material is caught by a canvas apron 24 loosely suspended from bars 25. A member 27 on rods 28 actuated by tension springs and by radial projections 32 on a shaft 33, hits against the underside of the apron and throws the material against the undersides of the goods. An air blast 43 removes excess material from the goods, and forces adhering material more firmly into the viscous coating. The surplus material is directed by plates 34, 35 to a helical conveyer 37 which delivers it to a bucket elevator which discharges it into the hopper 12. The machine is driven by an electric motor through a variable speed transmission. In a modification, Fig. 6, the material which falls through the pervious belt E is caught by the belt 101 which travels in the same direction as the belt E. The belt 101 gradually approaches the belt E and applies the material to the underside of the goods. The beltsupporting frame 106 is pivoted on the shaft 103 and the inclination of the belt 101 is adjusted by screw means 108. A scraper 110 regulates the thickness of the applied layer of material. The conveyer 100 returns material to the bucket conveyer as in the previous modification. In a further modification, Fig. 7, the excess material is caught in a trough 111 and is thrown into the path of an air blast 113 by a rotary paddle 112. The blast projects the material against the undersides of the goods.

Abstract: 857,024. Protective cut-out arrangements; thermal switches. ENGLISH ELECTRIC CO. Ltd. Oct. 21, 1957 [Oct. 19, 1956], No. 31838/56. Class 38 (5). In a protective or alarm arrangement, particularly for semi-conductor rectifier installations, any one of a plurality of fault-indicating devices responds to fault conditions in the protected circuit and at the same time as an alarm or tripping-device which is common to all the fault-indicating devices. In Fig. 1, the D.C. bus-bars 10, 11 are connected to the rectifier phases by conductors 12 and series striker-pin fuses 13. When any fuse 13 blows, its spring-biased pin 14 displaces a bar 15 against light compression-springs 17 to actuate the micro-switch 18. Alternatively main fuses fuses (Fig. 3, not shown) may be shunted by fuses of the striker-pin type but having lower current rating and arranged to operate in the manner described. The micro-switch contacts of a number of units are arranged when actuated to complete respective circuits a-a . . . d-d, so as to light a lamp 20 from the tapped transformer 28. Other lamps 20 are not lit since they are each effectively in series with two resistors 21. The bridge-rectifier connected relay 24, however, is energized, in series with one resistor 21, so that it opens contacts 24a to de-energize the coil 26 of the rectifier input contactor (not shown), closes contacts 24b to operate an alarm hooter 27 and closes contacts 24c for remote indicating or protective gear. Operation of a push-button 30 will then energize a relay 31 having contacts 31a, 31b arranged to disconnect the hooter 27 and " hold in the relay 31 until the contacts 24b are opened. Operation of the respective switch 32 of the lighted lamp disconnects the relay 24 which resets and is ready to operate in response to further fault conditions. The left-hand lamp 20 is energized by the operation of switches 34 controlled by the flow of cooling fluid to the rectifier. Testing push-buttons 33, 30a are provided; the former to disconnect the relay 24 and light all the lamps 20 and the latter to energize the hooter 27.

Abstract: 809,900. Skittle alleys. AMERICAN MACHINE & FOUNDRY CO. Oct. 14, 1957 [Oct. 12, 1956], No. 32013/57. Class 132(2) Relates to skittle alleys in which balls from a pit are rolled up a vertical track 18 to a return run-way 24 by an endless conveyer 20 frictionally engaging the balls, According to the invention, a ball on track 18 moves the conveyer away from the ball-receiving portion of the track so that a second ball cannot be engaged by the conveyer until the first ball has been discharged on to run-way 24. As shown, the elevator is disposed between two alleys from. the ball-pits of which balls can run through apertures 12 and down ramp 16, on to an arcuate lower section 26 of track 18. The periphery of the bottom wheel 28 of conveyer 20 is spaced less than a ball's diameter from track section 26 and a ball on the latter is carried forward by the conveyer which is swung upwards by the ball to allow this. The frame 30 carrying the top and bottom conveyer wheels 29, 28 is carried by top and bottom levers 94, 92 pivotally mounted at 80, 102 to allow the upward swinging of the conveyer. As the ball proceeds up track 18, the lowest part of the conveyer is spaced more than a ball's diameter from track section 26 so that a second ball will not be gripped. Frame 30 is telescopic, the parts being spring-urged apart to tension the conveyer. Motor-driven belt 70 drives the conveyer and passes over a jockey pulley 76, the arrangement being such that initial lifting of the conveyer tends to tighten the top run of belt 70, the motion of which thus Thelps to lift the conveyer. Spring 120 counterbalances in part the weight of the conveyer. Track 18 consists of two rods covered with resilient material and discharge pad 42 is reversible so that a worn side can be replaced By an unworn side.
