Title: Processing waste paper
IPC: D21B1/32
Filed: 1975-02-17
Abstract: 1463776 Pulping waste paper ESCHER WYSS GmbH 17 Feb 1975 [26 Feb 1974] 6606/75 Heading D2A [Also in Division B2] A stock obtained by pulping waste paper and containing less than 80% water is subject to an intensive mechanical shearing stress before separating foreign particles therefrom. Any aluminium foil or synthetic plastics foil present in the stock is rolled up cr curled as a result of the shearing stress applied thereto and forms compact granules which may be separated from the stock in a hydrocyclone or by screening. The curling may be assisted by heating the stock to a temperature at which the synthetic plastics material becomes plastic. In the embodiment shown, paper pulp from a stock pulper 21 passes to a second stock pulper 25 from which the good stock passes to a screening press 29, a heating screw 30 to which superheated steam is supplied and a dispersing apparatus 32. The latter is provided with a rotor and a stator with intermeshing teeth and subjects the stock to an intensive shearing stress. From the apparatus 32 the stock passes to a container 33 where it is diluted, a screening device 35 and a hydrocyclone 37. In another embodiment (not shown) the second stock pulper 25 is replaced by a hydrocyclone (5) and a deflaker (7).

Title: Process for the preparation of effect threads
IPC: D06P1/651
Filed: 1928-03-02
Abstract: 314,913. Chemische Fabric vorm. Sandoz, and Leemann, H., (Rheiner, A.). March 2, 1928. Addition to 280,493. Yarns and threads, treating with liquids.-The process of the parent Specification, according to which effect threads are manufactured by acetylation of vegetable fibres to the mono- or di-acetate stage, while employing an acetylating mixture consisting of acetic anhydride, acetic acid and one of the catalysts usually employed for the preparation of the triacetate, the composition of the mixture and the temperature employed being so chosen that the activity of the mixture is substantially moderated, in comparison with that of the mixtures used for the preparation of triacetate, is applied to mercerized vegetable fibres. Lustrous threads, which are no longer dyed by substantive dyestuffs, are thereby obtained. The reaction does not commence sufficiently quickly at ordinary temperatures with the acetylation mixtures described in the parent Specification, and higher temperatures, preferably above 40‹ C., may be employed. The process may also be modified by first treating the mercerized fibre with one or two ingredients of the acetylation mixture, the remaining ingredient or ingredients being added later. The working conditions may be varied, so that the conversion to mono- or diacetate takes place in any desired time, but in all cases the conditions are such that the activity of the mixture is substantially moderated, so that the process remains under perfect control. In examples (1) 100 parts of mercerized yarn are treated with 20 parts of zinc chloride, 100 parts of acetic anhydride and 880 parts of glacial acetic acid for 6 to 7 hours at 60‹ C. and (2) 100 parts of mercerized cotton are entered into 800 parts of glacial acetic acid, and 50 parts of zinc chloride and 250 parts of acetic anhydride are subsequently added.

Title: An improved means for the separation of dust from air or other gases by moistening
IPC: B01D47/10
Filed: 1931-03-04
Abstract: 374,442. Dust separators. HUMPHREYS, C., Glangarnant, Garnant, Carmarthenshire, and AMALGAMATED ANTHRACITE COLLIERIES, Ltd., Eagle Chambers, Swansea. March 4, 1931, No. 6729. [Class 8 (ii).] A i r o r gas is warmed and moistened with steam whilst traversing a passage leading to a dust separating chamber having pipes or tubes cooled by passage therethrough of air, water, &c., for deposition thereon of condensed steam and dust. Dustladen air is impelled through one or more conduits 2 and moistened by steam from injector nozzles 3. A turbine-driven fan may, however, be employed, the exhaust steam being used for the moistening operation. A series of tubes 4 mounted in bearings in the walls of a chamber 1 and slowly rotated, as by means of an endless chain 5 engaging sprocket wheels 6, provide a dust-depositing surface, the tubes being cooled internally by an air, water or other fluid circulation. Stationary scrapers 7 engage the undersides of the tubes, the detached dust falling into a bunker 8 in which it is moistened by a water sprinkler 9. A number of vertical slotted plates 11 are arranged between the tubes and air outlet 10 providing a further dust-depositing surface, a counterbalanced shutter 12 being readily tipped to discharge accumulated dust into the bunker.

Patent GB-657726-A (GB)
Title: Improvements in or relating to floor polishing machines
IPC: A47L11/16
Filed: 1949-03-11
Abstract: 657,726. Floor polishers. PATCHETT, G. W., and STERLING ENGINEERING CO., Ltd. March 11, 1949, No. 6746. [Class 138(i)] In an electric floor polisher of the type having two or more rotatable brushes, drive is transmitted frictionally from the motor shaft to one or more brush-carrying wheels, and from such wheel or wheels to one or more further brush-carrying wheels by an encircling driving belt, the bearing of each brush-carrying wheel being mounted eccentrically and being spring-urged in a direction to maintain the friction drive and tension the driving belt. Means are preferably provided for interrupting the frictional drive from the motor shaft when the handle is raised to a vertical inoperative position and for releasably locking the handle there. The polisher comprises a handle 12 terminating in a fork 10 the ends of which are pivoted to the brackets 9 on the casing 3 which encloses the brushdriving mechanism. The handle can be locked in a vertical position by a spring loaded plunger mounted on the bottom of the handle and which engages a detent 57 on top of the motor casing 2; the catch being releasable by depression of pedal 53. The motor spindle 17, Figs. 5, carries a driving pulley 18 which frictionally drives brush-carrying wheel 4a, fitted with a rubber tyre 29. Brush wheels 4b and 4c are driven from wheel 4a by a belt 59. The bearing of each brush wheel is carried by an eccentrically mounted bush 22, Fig. 6, which is rotatable on the fixed pin 24, so that rotation of the bush about its pin moves the wheel 4 laterally. Each bush is passed round a part of each peripheral formed with a peripheral groove 23 and has a pin 23a projecting radially from the groove. As shown in Fig. 5, a tension spring 30 or 31, anchored at one end, is groove and attached to the radially projecting pin 23a or 32 in such a manner that the springs tend to rotate the eccentric mountings to urge the wheel 4a against its driving pulley 18 and to urge the wheels 4b and 4c outwardly to tension the belt 59. When the handle 12, Fig. 1, is raised and latched in its vertical position, the drive between motor pulley 18 and wheel 4a is interrupted. This is effected by means of a projection 42 on the fork 10 which in the vertical position of the handle engages the flange 35 of two-armed lever 34, 36, Fig. 5, and moves the arm 36 against spring 39 to engage the radial pin 32, whereby the pin 32 and its eccentrically mounted bearing are moved so as to separate the wheel rim from its driving pulley 18.

Filed: 1946-03-05
Abstract: 622,216. Regulating switches. BEDGGOOD, V. March 5, 1946, No. 6869. [Class 38(v)] An on-load tap-changing switch comprises a rotary contact which engages the inner surface of a cylindrical fixed contact unit consisting of a number of insulated conducting segments which are held in position by inwardly acting radial forces produced by clamped external rings. The rotary contact comprises a pair of spring- pressed brushes and each conducting segment of the fixed contact unit is provided with an insert of insulating material situated towards one end of the segment, adjacent segments having the inserts at their opposite ends. The arrangement is such that as the brushes are rotated, one brush rests on the conducting part of a segment while the other brush rests on the insert, the first brush then resting on the insert of the next segment and the second brush engaging the conducting part. Current is conveyed to the brushes by means of a slip ring and through the centre tapping of a resistance, the ends of which are joined to the brushes. Fig. 3 shows a switch in section in which a is one of a number of segments arranged cylindrically. Each segment is formed with two oppositely inclined surfaces b which are engaged by a pair of correspondingly shaped rings c, d from which they are insulated by rings e. The rings c, d are clamped and drawn together by bolts and nuts f, thus producing an inward radial pressure on the segments a which are thus held rigidly in position. Adjacent segments are provided with insulating inserts g. The movable contacts of two brushes n mounted on pivoted holders carried by a rotary member h, whose spindle i is mounted in a spider j attached to the ring c. The brushes are connected to the ends of a resistance o, the centre point of which is connected to a slip ring against which a plunger p bears, which is connected to an external circuit. Each segment a may be joined to a tapping point on a transformer &c. The switch may operate in oil and when operated in air the spindle i may be arranged vertically to assist cooling by convection.

Title: Improvements in or relating to valve gear of internal combustion engines
IPC: F01L1/28
Filed: 1943-04-19
Abstract: 566,450. Valves. BOORER, A. April 19, 1943, Nos. 6954/44 and 6953/44. Divided out of 566,416. [Class 7 (vi)] In an engine having a valve chamber communicating through a master valve port with the cylinder and inlet valves for controlling the flow to the valve chamber of air and combustible mixture, and an exhaust valve, the air is supplied before the exhaust valve is closed and also before the mixture valve is opened, with or without continuance of the opening after the mixture valve has been closed and after bottom dead-centre has been reached. As shown, a rotary-sleeve admission valve 15 surrounds a fixed core 17 formed with separate admission ports for air and mixture and a single port opening towards the cylinder, the valve having co-operating ports. The ports are spaced apart along the length of the valve. A similar rotary sleeve valve 14 surrounds a water-cooled core 16 and controls the exhaust gases. Both valves communicate with a space behind a master valve 24 adapted to be opened continuously from towards the end of the firing stroke to the first part of the compression stroke. Early in the firing stroke, both sets of ports in the exhaust valve 14 are opened to permit rapid exhaustion of the burnt gases when the master valve 24 opens. Near the middle of the exhaust stroke, the air passage to the core 16 opens, but the port leading towards the cylinder remains closed, opening near the end of the stroke to scavenge the cylinder and thereafter provide a passage for the air and mixture. Early in the induction stroke, the port in the valve 15 controlling the passage of combustible mixture to the core 17 opens and the passage 21 to the exhaust valve 14 closes simultaneously. For the remainder of the inlet stroke, compressed air and combustible mixture enter the cylinder, the mixture being cut off at bottom dead-centre. After about a quarter of the compression stroke, the master valve closes, the air continuing to have access to the space behind it however until near the end of the stroke when the admission valve 14 simultaneously closes the air inlet to the core 17 and the outlet therefrom towards the cylinder. Specification 565,748 is referred to.
