Title: Improvements in rotary engines
IPC: F01B17/04
Filed: 1924-01-22
Abstract: 232,677. Yeo, A. J. Jan. 22, 1924. Compression engines; driving-gear.-In a revolving cylinder engine the pistons are connected to a support, which is independent of the cylinders and intermittently revolves in the same direction as the cylinders, reverse rotation of the support being prevented bv a detent. As shown in Fig. 1, the cylinders 3 are carried in a casing 2 which revolves continuously, all the impulses effecting movement of the casing in the same direction. The pistons are connected to arms 12 on the support 14, a detent 13 being arranged between the fixed shaft 1 and the support. The support has another pair of arms 15 connected by links 16 to cranks 17 driven by pinions 18 carried round on the cylinder casing and rolling over a fixed sun-wheel 19. When an impulse takes place the piston is held stationary by the detent, the cylinder casing moving forward; continued' movement causes the crank 17 to act on the support and return the piston into the cylinder. The cylinder may be curved in which case the pistons may be fixed to the arm 12. In a modification with radial or approximately radial cylinders 3, Fig. 3, the piston has two connecting-rods, one 23 connected to the support 24, the other 21 to a control crank 25 which is rotated from the cylinder casing through toothed gear. The engine may be a two- or four-stroke-cycle internal-combustion engine, in which case in the first described arrangement the valves may be worked from thebevel wheel 10, Fig. 1; or it mav be worked with steam or compressed air. The return movements of the pistons may be effected by fluid pressure in extra cylinders or by making the pistons double acting.

Abstract: 930,261. Load handling machines; engaging loads. KOVO-FINIS NARODNI PODNIK. Jan. 19, 1960 [Jan. 19, 1959], No. 1962/60. Classes 78 (1), 78 (3) and 78 (4). Apparatus for transferring batches of articles on a hanger 3 successively from one bath 10 to another in an electroplating plant, comprises a number of transfer stands A, B to each of which is pivoted an arm 1 on which is pivoted a hook 2 urged to the position shown in Fig. 2 by a spring-loaded pin 5; and an oppositely-acting spring 7 which is secured at its ends to the arm and to a member 8 which member is provided with a fork engaging a lug b on the hook. In operation, each arm 1 is swung, hydraulically, into position II where the hook 2 hits rod 13 of the hanger 3, and is deflected by its camming edge a to permit the hook 2 to snap behind rod 13. The arm is then swung about a horizontal axis to position III where the rod is deposited on a stand 9. During this movement of the arm the hook rotates relative to the arm thereby winding up spring 7 which, when the rod is deposited on the stand 9, unwinds and moves the hook to the dotted line position shown in Fig. 7 where it is ready to repeat the cycle of operations on the next oncoming hanger. The apparatus is controlled automatically by timing relays (not shown) which progress the hangers through the baths at a predetermined rate.

Title: Improvements in Safety Valves.
IPC: F01B25/00
Filed: 1917-02-09
Abstract: 104,007. Crosby Steam Gage & Valve Co., (Assignees of Clark, G. H.). Feb. 9, 1916, [Convention date]. Safety - valves. - A safety-valve adapted to open in either one or two stages has the parts of the valve member and seat contiguous to the actual contacting surfaces so shaped that, when the valve is open, the area of the escape passage so formed is substantially constant throughout its length. The valve member D is loaded by a spring and has a cylindrical extension E loosely fitting in a guide G. The seat is rounded at B<1> with a radius approximately equal to the predetermined normal full lift of the valve, and surrounding the actual contacting surface S, both the seat and valve member are curved upward at a gradually increasing inclination. The curved parts on the seat are formed on two adjustable rings R, W. If it is desired to construct. a valve adapted to open in two stages, the ring W is made relatively wide and adjusted to give a very small clearance when the valve is seated, while the ring R is given a more pronounced clearance and its curved surface developed to a steeper angle than in the case of a valve designed to open in one stage. A valve designed to open in one stage has a narrow ring W adjusted to give a wider clearance while the ring R is adjusted to give a less clearance.

Title: Improvements in resilient mountings
IPC: F16F1/54
Filed: 1945-01-26
Abstract: 602,735. Aero-engine mountings. LORD MANUFACTURING CO. Jan. 26, 1945, No. 2115. Convention date, Jan. 13, 1944. [Class 4] [Also in Group XXXII] In a mounting for a radial aircraft-engine, a supporting ring forming part of the airframe is connected with the engine by a circumferentially-spaced series of radial links, the axes of which intersect at a common point on the torque axis of the engine, each link having a universal connection with a respective bracket on the engine and embodying a resilient rubbersandwich type mounting (see Group XXXII), the elements of which are arranged to offer a greater resistance to deflection due to torque disturbances of the engine compared with disturbances due to movements of pitch and yaw. In the construction shown in Figs. 11, and 13 a common core for several rubbersandwich mountings securing an aircraft engine to a supporting ring 76, is formed by the ring 76 itself. Resilient elements 81, 85 are bonded to plates 82, 86 which engage the inner and outer surfaces respectively of the ring 76. The opposite surfaces of the resilient elements 81, 85 are bonded to backing members 80, 84 which are secured by a nut 88 and stem 92 passing through an opening 91 in the ring and integral with the ring member 97 of a balljoint 97, 98 by which the mounting is connected to a bracket 100 secured to the engine. The lateral curvature of members 80, 84 is slightly different from the cross-sectional curvature of the ring 76 at most cross sections so as to enable a uniform rocking action to be obtained. The mountings are assembled within the ring 76 by inserting them through an opening in the ring and pulling them round to the respective openings 91, by a cord. Alternatively, the ring 76 may be discontinuous at one point at which the mountings are introduced, and may be welded together when all the mountings are in position. In a similar alternative construction (Figs. 19-21 not shown), a split fixture connected to the engine by the kind of ball-joint above described, completely surrounds the tube 76 and is spaced from it by one rubber sandwich element on the engine side and two similar spaced elements on the opposite side. Bolts which secure the two halves of the fixture pass through holes in T-shaped extensions to the outer bonding plates of the rubber sandwich units to hold the latter in correct spacing. In alternative constructions (Figs. 1-8, not shown), the resilient mountings are positioned at an intermediate point in the radial connecting links. In one of these alternative constructions the universal connection is constituted by a second rubber sandwich mounting in series with the existing mounting. Specifications 552,888 and 558,034 are referred to.

Title: Bending machine for bars and tubes
IPC: B21D7/14
Filed: 1956-01-24
Abstract: 819,310. Angular bending. HILGERS MASCHINEN-UND APPARATE HAFTUNG. Jan. 24, 1956 [Jan. 24, 1955], No. 2338/56. Class 83 (4). A tube- or bar-bending machine of the type in which the tube is bent around a former by the rotation thereof and in which the amount of such rotation is limited by an abutment on a carrier, the abutment also serving to return the former, the drive thereto being then switched off, the carrier having a plurality of such abutments thereon, one for each of succession of bends formed, which are presented on the step-bystep rotation of the carrier is characterized in that the carrier is provided with stops which return' the carrier to its initial position and switch off the drive thereto after each series of bends has been made. A tube is bent round a former on a rotary table 10 driven by a chain 11 moved by an hydraulically operated piston 12. The angle of rotation of the table 10 is determined by one of a number of abutments 14, 14<SP>1</SP> on a drum carrier 24 moved by an arm 28 on the piston 12 to engage a switch 15 to reverse the piston 12, a switch 17 engaged by an abutment ring 16 rigid with the carrier 24 stops the piston 12 on the completion of such reverse movement. A magnet 18 energized on starting the machine moves a piston in a housing 19 to allow fluid flow from a supply 21 to an hydraulic motor 22 which rotates a hollow shaft 23 carrying the drum 24. A cam disc 25 on a shaft 27 keyed to the shaft 23 engages a switch 26 so that as the switch falls from one projection 29 thereon and runs to the next 30 the current for the magnet 18 is interrupted to stop the motor 22, the current to the magnet 18 being switched on again by switch means, not shown, every time a new bend is made. When all the bends on a workpiece have been made an adjustable stop 31 on the disc 25 engages a switch 32 to energize the magnet 18 in a reverse sense so that the motor is reversed and the disc 25 and drum 24 are turned back until a second adjustable stop 34 on the disc 25 engages a switch 35 to de-energize the magnet 18 and stop the motor 22. The bent tube is removed and a new tube is then introduced into the machine and the series of bends defined by the abutments 14, 14<SP>1</SP> effected. The stops 31, 34 are appropriately set around the disc 25 to bring the correct sector of the drum 24 into control position. Parallel to the mandrel rod of the machine a shaft 36 carrying resilient tube and engaging abutments 37, 37<SP>1</SP> is mounted. At the beginning of a bending series the abutments 37, 37<SP>1</SP> have been moved away from the mandrel rod by hydraulic means 40 operated from the housing 19 and the tube is pushed over the rod up to a setting ring thereon. After the first bend has been completed the fingers 37, 37<SP>1</SP> are moved back to press against the tube to be bent and mandrel rod to determine the position of the tube prior to the next bend. At the end of the bending series when the motor 22 is reversed the fingers 37, 37<SP>1</SP> are moved away from the tube.

Title: Improvements in or relating to the over-end winding of yarns, and to packages of yarn so wound
Inventor: KEY KENNETH ANDREW
IPC: D01H1/30
Filed: 1967-01-17
Abstract: 1,217,321. Yarn package. IMPERIAL CHEMICAL INDUSTRIES Ltd. 29 Dec., 1967 [17 Jan., 1967], No. 2476/67. Heading B8M. [Also in Divisions D1-D2] A yarn package having no ridges due to wind ratio patterning greater than 4 thousandths of an inch in height when measured by a 3/32 inch diameter probe of a "Talysurf" (Trade Mark) recording instrument with less than 10 gms. pressure on the stylus, is produced by winding the yarn on a ring and traveller with ring tilt of which the wave amplitude is greater than the traverse increment per revolution of the point of lay, according to one or more values of constant wind ratio calculated to avoid regions of patterning in the package and maintaining the wind ratio " programme " at least during a part of the winding. The wind ratio is preferably not a ratio of whole numbers either of which is less than 5; the wind ratio preferably lies between 1À0 and 2À0. Wind ratio is the number of revolution of the point of lay of the yarn around the package for each revolution of the traveller around the tilted ring. The wind ratio may be kept constant by varying the spindle speed and/or the delivery speed. The speed which is varied may be varied in accordance with a " programme " creating means, e.g. a cam or analogue computer. The speed of the traveller may be monitored photoelectrically or magnetically and a resulting signal fed to a circuit in which the measured speed is compared with the desired speed and a corrective action, e.g. of the spindle speed, made.
