Title: Improvements in tube bending machines
IPC: B21D9/07
Filed: 1942-04-09
Abstract: 550,827. Tube-bending machines. ARMSTRONG, J. J. V. (Parker, A. L.). April 9, 1942, No. 4633. [Class 83 (iv)] A tube-bending machine, of the type having a former block 34 to which the tube 112 is clamped by a vice 99 and which is rotated by an electric motor to bend the tube about the block 34, is provided with circuit control-means to initiate bending and return cycles and to terminate the first when a predetermined bend has been formed. The pins 31, 32 are carried by a shaft 23, Fig. 6, driven through reducing and variable speed gearing by a reversing motor. The block 34 can be placed on axial and driving pins 31, 32 in position for right- or; as shown, left-hand bends. For right-hand bends a lever 91, carrying the vice 99, is swung 180 degrees about the pin 32 and a lever 57, Fig. 1, about the shaft 23 so that it engages a reversing switch S for the bending motor. When the lever 57 is thus reversed, the guide 72 and its roller support 69, Fig. 4, and operating mechanism 77, 82, 66, 64 which the lever carries, is mounted on its other side. The mandrel 113 is carried by a slide 116, Fig. 1, which can be clamped in any desired lateral position on a guide 120. With the levers 57, 91 adjacent and a tube 112 arranged between the block 34 and the multifaced blocks 102 and 74, Figs. 4 and 6. of the vice and guide and over the mandrel 113, the vice and guides are pressed against the tube by toggles 104 and 77, operated by pistons 82, controlled by a reversing valve which is moved by a solenoid energized by pressing a button 15, Fig. 1, the toggle 77 closing a safety switch G in the circuit of the bending motor as it straightens. Another switch, closed by pressing the button 15, acts, when the switch G is closed and according to the position of the switch S, to close the necessary switches to cause the bending motor to rotate in the desired direction. A dial 145, Fig. 6, driven from an intermediate shaft 36, shows the progress of the bend and a heartshaped cam 25, on the shaft 23, moves a slide 28 until it engages a stop 131, adjusted by a handle 136, according to the desired angle of bend, this angle being indicated on a dial 142 moved also by said handle. When the slide 28 engages the stop 131 this is moved to the left with its operating means and a cam 146 on this means actuates a multiple switch to energize a motor 126, Fig. 1, to withdraw the mandrel, deenergize the bending motor and energize a solenoid to apply a brake to stop this motor. The withdrawal of the mandrel is stopped by a collar 128 and switch H which also effects the unclamping of the tube and sets contacts for the return of the block 34. This is effected, after removing the bent tube, by pressing a button 16, which also advances the mandrel until stopped, in correct position, by a switch K actuated by an adjustable collar 1281. Buttons 11, 12 and 13 are used for operating separate parts during set-ups and button 14 for stopping the whole at any time.

Filed: 1941-04-09
Abstract: 548,298. Spring devices for motor - cycles. MINETT, D. C. April 9, 1941, No. 4707. [Class 136 (iii)] A shock-absorber for the front or back wheel comprises two primary cylinders 1 each containing a piston 3 carried on a rod 4 constituting or being joined to a prong of the fork (as shown, the front fork). The cylinders contain oil and communicate by pipes 9 with a cup 17 secured in the upper part of a secondary cylinder 8 containing a spring- supported piston 10. When the wheel meets a bump, the piston 3 rise and oil is forced into the cup 17 and thence into the cylinder 8 through a bleed vent 21 constituted by the lower end 19 of a valve 20 and the edges of an aperture in the cup. On rebound, the liquid leaving the cylinder 8 raises a ball valve 27 and passes via ports 30 to the cup and thence back to the cylinders 1. In the case of a back wheel, each cylinder is divided into an upper and a lower portion, an elongated piston 3 extending between the portions and having secured thereto a forked member which receives one end of the wheel spindle. The secondary cylinder 8 may be positioned other than as shown, e.g. on the forward part of the machine in the case of a front wheel or under the saddle in the case of a back wheel.

Title: Passive containment system

Filed: 1975-02-04
Abstract: 1507688 Reactor safety NUCLEDYNE ENG CORP 4 Feb 1975 4797/75 Heading G6C In a nuclear reactor plant comprising a reactor, a reactor coolant system including conduit means for circulating high-pressure hightemperature coolant within the coolant system, steam generator means, and a containment structure sealingly enclosing at least the reactor and its coolant system, containment of the plant during accidental loss of coolant is effected by sensing a first preselected pressure differential between the coolant and a first separate body of pressurized cooling liquid, causing the cooling liquid to start to flow into the coolant system and in so doing reducing the pressure of the pressurized cooling liquid, sensing the decreasing pressure thereof until a second preselected pressure differential is attained between the pressurized cooling liquid and the steam within the steam generator means, and causing the steam to be directed to the pressurized cooling liquid when the second pressure differential is attained to thereby provide an additional pumping force to the cooling liquid to continue the flow of the cooling liquid into the coolant system in order to replenish such coolant as has been lost. The pressurized cooling liquid may be chilled. Further steps as follows may be added: permitting such coolant as is lost to vapourize within the containment structure to cause the latter's interior to attain a first relatively high vapour pressure, sensing the attainment of a third preselected pressure differential between that interior and a second separate body of second cooling liquid when the first relatively high vapour pressure is attained, then completing communication between vapour at that pressure and the second cooling liquid to thereby heat and simultaneously pressurize the second cooling liquid, and permitting the latter to flood the interior of the containment structure. The embodiment is a pressurized water reactor with four loops of reactor coolant and includes the following features: (i) stored "deluge" fluid, the reactor vessel refill fluid and the fluid in the annulus between primary and secondary containers have chemicals in solution to serve as neutron poisons (e.g. boron, cadmium, hafnium), oxygen getters (e.g. hydrazine, sodium sulphite), fission product getters (e.g. sodium hydroxide, sodium thiosulphate), and freezing point depressants (e.g. ethylene glycol), (ii) high vacuum in the primary containment and removal of thereform of specified auxiliary systems and massive concrete structures, and (iii) measures to protect against accidental reactor surges.
