Patent GB-648990-A (GB)
Title: Spring construction more especially for balancing sash-windows or the like
IPC: E05D13/00
Filed: 1948-03-05
Abstract: 648,990. Springs. VRIES, A. DE, and VRIES, L. DE. March 5, 1948, No. 6964. [Class 108(iii)] [Also in Group X] A spring construction, more especially for balancing sash windows &c. comprises one or more springs which on being extended or compressed are simultaneously wound up or unwound whereby the reaction force is varied in a desired manner over the compression or extension range. The winding or unwinding may be effected by a twisted . strip or by a screw threaded bar. The arrangement showr in Fig. 1 comprises a pair of telescoping tubes 1, 2 containing two halves 3, 4 of a coil spring which merge at 5 where they are connected to a tube 7 by a pin 6. The tube 7 is slotted at both ends 8 to receive two spiral members 9, the twists of which are reversed at points 10 and which are connected with the spring ends 11. A 25 Kg. window sash is attached to the upper end of tube 2, and the lower end of tube 1 is attached to the frame. The spring halves 3, 4 are biassed to exert an upward force of 15 Kgs. and to exert a torque on the tube 7, i.e. they tend to unwind in a clockwise direction as viewed from above. so that the vertical component of the torque which will resist compression of the balance is 10 Kgs. Thus the effective upward force on the sash is 25 Kgs. As the sash is lowered to the halfway position the compression force of the spring increases to 25 Kgs. and the tube 7 rotates to wind up the spring, but due to the increase in pitch of the spirals 9 the vertical components of the torque decrease and become zero when the slots are at points 10. The resultant upward force is therefore 25 Kgs. When the sash is further lowered the force due to the compression of the spring increases to 35 Kgs., and the vertical component of the torque, because 'of the reversal of direction and decrease in pitch of the spirals, tend to contract the spring balance with a force of 10 Kgs. Thus the effective upward force is again 25 Kgs., the weight of the sash. In the construction shown in Fig. 2 the twisted strip 12 is fastened to the window frame at 13 and 16, and the slotted bushing 14. slidable on the strip, is secured to the spring 15 which is fixed at the upper end to the frame at 16. When the window is moved the projection 17 thereon carries the bushing 14 which is also rotated by the strip. The spring is therefore simultaneously stretched and wound as the window is closed, and compressed or unwound as it is raised. As the spring is tensioned, on closing, it exerts an increasing upward vertical force, but the vertical component of the torque exerted on the spiral decreases at the same rate. because of the increase in the pitch of the spiral. Thus the effective upward force remains constant. Specification 648,989 is referred to.

Abstract: 1383032 Vehicle driving and steering gear BKALTENEGGER 15 Feb 1972 [26 Feb 1971] 7033/72 Heading B7H A vehicle 1 having non-deflectable wheels 2, 3, 4, 5 is provided with a motor 12 and a transmission unit 13 which drives the wheels at one side independently of the wheels at the other side, either forwardly, in reverse or idling, to provide a selective drive arrangement for steering. As described the input shaft 18 for the transmission unit 13 drives two separate gear trains (Fig. 3). The train at the left of Fig. 3 drives output shaft 44 (Fig. 5) and the train at the right of Fig. 3 drives output shaft 44<SP>1</SP>. Output shaft 44 drives the wheels 4, 5 via gears 58 to 62 and output shaft 44<SP>1</SP> drives the wheels 2, 3 via gears 58<SP>1</SP> to 62<SP>1</SP>. The two gear trains in the unit 13 are identical so that only one need be described. The input shaft 18 (Fig. 5) is provided with two gear-wheels 22, 23 which are in constant mesh with gear-wheels 24, 25 (Fig. 6) which can be coupled to shaft 28 by clutches 31 and 32. Thus by engaging either clutch 31 to 32 a first-gear or second-gear ratio can be selected. The shaft 28 carries gear-wheel 34 which meshes with gear-wheel 35 on shaft 36. The shaft 36 drives shaft 39 either directly through gears 30 and 38 and clutch 41, or indirectly through a reverse gear shaft 45 (Fig. 3), gear 48 and clutch 42. Thus by engaging either clutch 41 or 42 a forward or reverse drive can be selected. The shaft 39 drives output shaft 44 via gears 50, 43. All the clutches are hydraulically operated and are supplied with pressure fluid from a pump 63 (Fig. 5) on the input shaft 18. In operation the vehicle can be driven in a straight line, either forwardly or in reverse, at first gear or second gear speeds, or can be driven along a curve by driving the wheels at one side in first gear and the wheels at the other side in second gear. Alternatively the vehicle can be turned by driving the wheels at one side forwardly and the wheels at the other side in reverse. The wheels 2, 3, 4, 5 may be ground engaging wheels (Fig. 1) or the drive wheels for an endless track 11 (Fig. 3).

Filed: 1937-03-10
Abstract: 491,861. Winding and unwinding webs. METTLER, H. W. March 10, 1937, No. 7036. Convention date, April 11, 1936. [Class 100 (i)] In web winding or unwinding apparatus of the kind in which the winding or unwinding drum is turned by a hydraulically driven bucket wheel, the means whereby the liquid is delivered to the bucket wheel is adjustable relatively to, and preferably on each side of, the vertical plane containing the axis of the wheel. In one form, Fig. 1, the liquid supply pipe 3 is adjustable between the positions C and D to vary the magnitude and direction of the torque applied to the wheel 2 driving the winding or unwinding drum 1. A valve 8 permits adjustment of the rate of delivery of the liquid. In another form, Fig. 3, two drums 10, 11 are provided with bucket wheels 15, 16, the wheel on the unwinding drum serving to apply a braking torque to the drum. As the winding proceeds, the diameter of the material on the drum 10 increases and that of the material on the drum 11 decreases. For constant tension of the material, the torque on the drum 10 must increase and that on the drum 11 must decrease and these variations of torque are effected automatically by the construction shown, since less water is retained in the buckets as the speed of the buckets increases.

Sept. 17, 1931, Nos. 7101/33 (divided on 393,297), 26215/31, 28145/31, 33190/31, 1648/32, 1921/32, and 4739/32. [Classes 51 (ii) and 55 (i).] An externally heated rotary retort comprises an inner element formed by walls 2, 3 containing an annular space 4 through which heating gases pass, the inner element being supported by an outer element or shell 1 to which it is slidingly connected and by which it is rotated, a gas being passed in the space 14 between the elements to prevent heating of the outer shell 1. This retort is suitable for carrying out the process described in Specification 393,297. The inner drum 2 which may be made of a series of welded cylindrical sections, is connected to the outer drum 3 by resilient members 6 secured to rings welded to the sections 2, 3 which may move relatively in a radial direction. To compensate for longitudinal expansion the plates 3 are corrugated at 7. The members 6 have keyways 9 in which slide pins 10 carried by the shell 1. Insulating jackets 13, 8 are provided on the shell 1, and inner element respectively. Cool gas, such as spent flue gas, is passed through the space 14 to insulate the shell 1 from the heat of the heating space 4. The rotary cylinder is mounted on rollers, and its ends extend into stationary heads B, C, gaseous means being provided as described in Specification 393,306 to prevent escape or entry of heating or distillation gases. These means comprise the use of maze plates 27 adjacent the heating passage, plates 28 adjacent the cool gas passage, and plates at 29, 30 to prevent escape of distillates or heating gases, or the mixing of these gases. The heads B, C provide passages for the entry and exit of the heating gases in the annular space 4, and of the cooling gases in the space 14, and are spring-mounted. Scraping means are provided of the kind described in Specification 393,303, comprising a flexible support 44 from which are suspended scrapers 43. The temperature of the inner element is registered by mounting on the outer shell a split ring 45, Fig. 9, connected with the inner element by radial pins 46, a scale 48 being made on one end of the ring, and a pointer provided. On expansion of the inner element due to heat, the ends of the ring are forced apart, and a measure of the temperature obtained. A thermostat is used to regulate the supply of air and fuel gas to the combustion chamber from which the hot gases are supplied to the retort. The coke ovoids are delivered to a gastight shoot leading to a conveyer 49 on to which the raw coal is fed, so that the coal covers the coke, and is thus preheated. The coke powder from a crusher, and the preheated comminuted coal, are mixed in a drum into which hot heavy oils from the process are introduced, and the blend is fed to the retort.
