Patent NL-179156-B (NL)
IPC: B62D5/06
Filed: 1977-02-16
Abstract: An improved fluid flow control apparatus is utilized in association with a vehicle having a single variable displacement pump for supplying fluid to both a steering apparatus and an auxiliary apparatus. The fluid flow control apparatus includes a pair of variable size orifices one of which is associated with the steering apparatus and the other of which is associated with the auxiliary apparatus. Upon actuation of either the steering or auxiliary apparatus, the size of the associated orifice is varied to provide a variation in a load signal and effect a change in the displacement of the pump. During simultaneous operation of both the steering and auxiliary apparatus, a priority valve assembly is utilized to block fluid flow to the auxiliary apparatus if the fluid output from the pump is insufficient to satisfy the demand for steering fluid. The priority valve assembly includes a main valve member with an internal chamber in which a secondary valve member or piston is disposed. Upon initiation of a steering operation with the auxiliary apparatus in an inactive condition, the secondary valve member moves toward a closed position. If at this time the demand for steering fluid is sufficiently great, the secondary valve member blocks fluid flow to the auxiliary apparatus.

Abstract: 1,109,499. Variable-ratio gears. BORGWARNER CORPORATION. 30 July, 1965 [3 Aug., 1964], No. 32798/65. Headings F2C and F2D. A variable-ratio gear comprises a torque converter 12 having an impeller 20, a one-way mounted reactor 22 and contra rotating turbines 21, 23 respectively connected to a planet carrier 36 and a sun gear 32 of a planetary gearing 30 having two sets of intermeshing planet gears, one set 39, 37 meshing the sun gear 32 and a ring gear 34 which is connected to a one-way brake 48, and the other set of intermeshing planets 40, 38 meshing an output sun 33 and a ring gear 35 which can be stationed by a brake 46 for reverse. The planet carrier 36 is fast with the ring gear of a planetary gear 31 having a planet carrier 50 fast with the output sun 33 and a sun gear 52 connectible to its ring gear by a clutch 60 for a normal drive range and stationed by a brake 61 for a low speed drive range. In operation, for normal forward drive the clutch 60 is engaged so that the turbine 21 is directly connected to the output shaft 11 as the planetary gear 31 is locked solid. At low forward speeds the reactor 22 is stationed by a one-way brake 26 and the turbine 23, and thus the sun 32, is driven in reverse. The one-way brake 48 stations the ring gear 34 and the sun gear 32 drives the planet carrier 36 and thus the output shaft 11 forwardly at a reduced ratio. At higher forward speeds the reactor 22 floats freely and the one-way brake also releases so that the turbine 21 drives the output shaft at a 1 : 1 ratio. For a low drive range clutch 60 is disengaged and brake 61 applied to provide a step-down ratio between the planet carrier 36 and the output shaft 11.

Title: Method and arrangement for plasma beam remelting of a surface layer on a plane workpiece of metal with parallel side edges
Inventor: PATON B E
IPC: H05B7/18
Filed: 1981-10-26
Abstract: The invention concerns a method and an arrangement for plasma beam remelting of a superficial layer on a planar workpiece of metal with parallel side edges, wherein one forms a pool of molten metal on a workpiece placed in a mould by heating of the workpiece by using a plasma torch fed with a plasma-forming gas and electric current during simultaneous relative motion between the workpiece and the plasma torches along the parallel edges of the workpiece. To enable the creation of a better remelting at a faster work pace to achieve an even more faultless surface of the workpiece than heretofore, the invention now proposes that the workpiece 1 be placed horizontally in the mould in its starting position and the plasma torches 6 be arranged above the workpiece 1 in a row and perpendicular to its parallel edges 1a, 1b, so that the anode spots for the plasma torches 6a, 6b situated at the ends of the row of torches lie within the edges of the workpiece 1 to form a pool 8 of molten metal which extends between these edges, and during the course of the remelting the plasma torch 6 and the workpiece 1 are moved relative to each other in a horizontal plane to form a remelted layer with a thickness equal to the depth of the metal pool 8 on the entire surface of the workpiece 1 as the pool moves over it.

Date Jul. 28, 1988.An eccentric gear comprising a stationary gear wheel (2) and an eccentric gear wheel (9). The eccentric wheel is freely mounted on the input shaft and is driven round by eccentric means (4, 6) causing the eccentric wheel to roll round the internal teeth on the stationary wheel. A driving dog transmits the slow rotation of the eccentric wheel to an output shaft (14). Distinguishing for the invention is that the teeth are corrected such that the eccentric wheel is adjusted with the aid of the two eccentric means such that there is practically no backlash. A computer calculated least clearance between respective top lands on the teeth is obtained with respect to tooth meshing. The eccentric means comprises two cylindrical sleeves arranged eccentrically one in the other. At one end part of each of the sleeves, one of which is arranged eccentrically in the other, there is a radially outstanding tongue (5, 7). These tongues serve as counterweights balancing the imbalance moment of the satellite gear wheel which is due to its eccentric mounting on the input shaft. Backlash and play are eliminated by turning the sleeves of the eccentric means relative to each other.

Title: Spring assembly for manoeuvring a lifting door
Inventor: OLOFSSON S
IPC: E05D13/00
Filed: 1987-06-24
Abstract: A spring assembly for manoeuvring a garage door or the like comprises a helical spring 8 and a rigid pull rod 11 cooperating with the latter and extending through it, which pull rod 11 is mounted securely on and projects from an attachment 6 and at its free end has a first holder 10 against which one end of the spring 8 is in contact. The spring 8 is enclosed for reasons of protection in a tube 9 which is coupled to a link mechanism 15 which in turn is coupled to the door. In the tube 9 there is a second holder 12 against which the other end of the spring 8 is in contact and which, upon compression of the spring 8, is driven in the direction towards the holder 10 of the pull rod 11 by longitudinal displacement of the casing 9. Both holders 10, 12 and the spring 8 tensioned between them are at all times located inside the tube 9, even upon full compression or full extension of the spring 8, as a result of which the risk of jamming is avoided. For the purpose of counteracting friction, the cross sectional diameter d of the pull rod 11 is considerably smaller than the internal diameter D of the helical spring 8. A plastic sleeve 16 is preferably inserted into the tube 9 in order to counteract friction between the inside of the tube 9 and the outside of the spring 8. <IMAGE>

IPC: D21G9/00
Filed: 1990-09-07
Abstract: It is generally difficult to engage a flexible press roll jacket 2 on a circular end wall 3 of a press roll since the flexible jacket 2 tends to assume a shape which is other than cylindrical. This difficulty is overcome by using an auxiliary instrument 1 which has an elongate recess 13 for receiving an elongate section of an edge zone of the jacket 2. The instrument is curved so that it supports the edge section of the jacket essentially on a radius R10 which corresponds to the circular end wall periphery. The instrument has at least one grip section 17 intended to be gripped by a hand. The recess 13 is preferably designed to receive the edge section of the jacket with a light press fit, and one or more screws 21 can be arranged to clamp a section of the edge zone of the jacket securely against a radially internal wall 11 in the recess 13. The instrument can be made up of flat sheets 19, 20 of steel, and the radially outer side wall 16 of the recess 13 can consist of a plurality of flat fingers 14 evenly distributed in the circumferential direction and extending sidewards. <IMAGE>
