Title: Improvements in or relating to means for regulating the relative fibre content or density of stock mixtures for the manufacture of paper
IPC: D21F1/08
Filed: 1934-05-22
Abstract: 423,646. Regulating consistency of paper pulp. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M.), Heidenheim-on-Brenz, Wurtemberg, Germany. May 22, 1934, No. 15345. Convention date, May 20, 1933. [Class 96] The fibre content of pulp for paper-manufacture is regulated by a float C &c. controlling a dilution-water slide valve E, a metering device, e.g. a bucket-wheel B, which gives a constant flow of diluted pulp, being located between the water-supply point and an outlet a<4>. Movement of the float actuates contacts d<1>, d<2> of a reversible motor D controlling the valve E, the water being mixed with the pulp by a paddle F. The outlet a<4>, the speed of the bucket-wheel B, and the contacts d<1>, d<2> are adjustable. The wheel B has holes b<2> for air, adjacent the hub, allowing regular flow of pulp from the compartments of the wheel B. Hydraulic or pneumatic means may replace the electrical means for actuating the valve E, with pneumatic means, a feeler may replace the float C.

Title: Method and apparatus for starting electromotors by means of an automatic starting coupling
IPC: H02P1/12
Filed: 1926-06-18
Abstract: 253,933. Albo Kupplung Ges., and Obermoser, K. June 18, 1925, [Convention date]. Driving-arrangements. - An alternating-current electric motor is connected to its load by an automatic clutch in which the clutching action is not initiated until the motor has ceased to accelerate and a time-lag device is provided to allow time for the starting connection of the motor to be cut out after maximum speed has been attained but before the load is applied. On the shaft W, Figs. 1 and 2, is keyed a flat cylinder M housed within the driven member R of the clutch. The cylinder has on its sides spiral slots A in which engage rollers Q carried by a movable coupling element K. While the driven shaft is accelerating in the direction shown by the arrow, the rollers Q. occupy the position shown in Fig. 2, in which the coupling element K is not in contact with the housing R. When the motor attains a constant speed, the rollers Q move slowly into the position D and in this position the clutch parts rotate together. The speed with which the rollers travel along the slots may be regulated by suitably choosing the liquid medium in the clutch. In a modification, Fig. 3, a sleeve M is keyed to the driving shaft Wand around this is mounted a coupling member in the form of a loose pulley, comprising two flange-like portions R<1>, R<2> screwed together to enclose a hollow space. Friction surfaces r on the inner side of the pulley co-operate with sector-shaped coupling elements E driven from the sleeve M by teeth M<1>. Vanes E<2> carried by the coupling elements rotate in an annular space between the pulley sections, and the width of this space is varied by a spring-urged annular piston C, which, in the position of rest shown, bears against the sides of the vanes. If liquid is admitted into the coupling and the shaft rotated, the centrifugal action of the vanes puts the liquid under pressure. This pressure acts on the coupling elements E in opposition to centrifugal force, so that tne drive is not taken up. The annular piston is moved outward slowly by the hydraulic pressure, the speed of movement being controlled by a valve Y so that the coupling takes up the drive gradually. As soon as the coupling stops, the piston returns, a spring- controlled ball or other valve U being provided to allow quick movement. If it is desired to retard the motion of the piston during uncoupling, the valve U may be omitted.

Title: Improvements in or relating to control valves for hydraulic systems for hydraulic presses
IPC: B30B15/18
Filed: 1942-11-12
Abstract: 564,190. Hydraulic presses. ERNST, W. Nov. 12, 1942, No. 15996. Convention date, Jan. 10. [Class 69 (ii)] In a hydraulic press having a piston 75 both advanced and retracted by fluid pressure from, for example, a reversible motor 96, a valve 9 is adapted, as the piston 75 reaches the end of its stroke and pressure builds up behind it, to establish a byepass which when the -pump reverses byepasses the retractive fluid admitted below the piston, the byepass then being automatically and gradually decreased at a rate determined by an adjustable choke and that is independent of the rate of decrease in pressure above the piston. The increased pressure at the end of the forward stroke also serves, in the arrangement shown, to operate a switch 86 which breaks the circuit of a solenoid 87 so that a rod 92 moves to the left and a servomotor 95 reverses the pump 96 ; at the end of the return of the piston 75 a collar 101 on the piston returns the rod 92 to a neutral position. The valve 9, Fig. 2, comprises a main plunger 15 movable against a return spring 21 by fluid pressure introduced at 28 and serving then to connect an inlet port 26 with an exhaust port 31 and the operating port 28 with a channel 62 leading to an auxiliary bore which contains a plunger 14 movable to the left against a spring 54 by fluid pressure introduced at 67 through a channel connecting 67 with a passage 64 permanently connected with the inlet port 26. The ports 26, 28 are connected to the hydraulic system as shown in Fig. 1. When, in the forward stroke of the piston 75, resistance is offered by a workpiece and pressure builds up above the piston, this pressure, acting through line 80, port 26, passages 64, 67 moves the auxiliary plunger 14 to the left. When the pump 96 reverses, the pressure from it acting along lines 108 and 28 moves the main plunger 65 to the left so that, instead of acting to push up the piston 75, some of it is byepassed through 28, 62 to an exhaust 60 now connected to 62 owing to the movement of the auxiliary plunger. This byepass is then gradually throttled at 48 as the auxiliary plunger 14 moves to the right owing to the decreased pressure in the passages 67, 64 which are now, as well as the port 26, connected to the exhaust 31. An adjustable choke between 67 and 64 regulates the speed of movement of plunger 14 and hence the rate at which pressure below the piston 75 increases. Specifications 519,824, [Group XXXVII], and 535,625 are referred to.

Filed: 1924-07-04
Abstract: 219,298. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Johnson, J. F.). July 16, 1923, [Convention date]. Dynamos and motors, cooling; enveloping in special media. -In a cooling system for a dynamo-electric machine in which air or other gaseous medium circulates in a closed circuit, oxygen is removed from the medium to prevent fire in the system. In the form shown in Fig. 1, a flame is used at 24 in a system comprising inlet and outlet trunks 11<1>, 11 and a cooler 13 through which air is driven by a fan 14 on the dynamo 6. Fuel for the flame is supplied through a pipe 25 and valve 15 and air is admitted through a valve 17 to maintain the flame when the oxygen content of the cooling medium becomes too low to support combustion. The heat generated by the flame is absorbed by the cooler 13 and a peep-hole 23 enables the condition of the flame to be observed. The air and fuel may be controlled by hand or automatically by means of an oxygendetecting element 18 immersed in the cooling medium and forming one arm of a bridge circuit which controls the current in a solenoid 20. The solenoid plunger is linked to the valves 15, 17 so as to increase the flame in proportion to the oxygen content of the system. The element 18 may consist of a resistance wire associated with phosphorus compounds which develop heat when exposed to oxygen. The air may be introduced at 17 so as to maintain the pressure within the cooling system above that of the atmosphere and so give an outward leakage without the possibility of fresh air entering the system. In alternative forms, the oxygen is absorbed by a lamp, by an oxygen-absorbing material, such as iron or copper filings electrically heated or by decomposing animal or vegetable material.
