Abstract: 1,245,579. Tube joints. BABCOCK & WILCOX Ltd. 25 Oct., 1968 [10 Oct., 1967], No. 46309/67. Heading F2G. [Also in Division B3] A method of assembling a tube wall of a fluid heating unit, includes welding together a plurality of tube lengths 4 and spacer strips 8 to form a tube panel, forming a pressure vessel 10 with apertures 12 corresponding to the tube end portions 6, inserting and securing expanding collet mandrels 22 in spaced tube end portions, inserting tapered guides or thimbles 14 in the remaining tube ends, positioning the mandrels and guides in register with the apertures 12, effecting relative movement between the mandrels and the pressure vessel to draw the end portions of the tube lengths into the apertures, removing the mandrels and guides and securing the tube end portions. Each mandrel 22 includes a stepped cylindrical sleeve 24, including a groove 32, into which tail-pieces 33 of jaws 34 are inserted. Aligned apertures 44, 46 are provided in pieces 33 and mandrel 24, which apertures co-operate with balls 50 to allow pivotal movement of the jaws. An arbor 52 having a frusto-conical head 54 is inserted into the mandrel and the head 54 expands the jaws 34 against the action of a retaining ring 48. The forward end 56 of the arbor is threaded for co-operation with a nut 58, rotation of which advances or retracts the mandrel. A locking thimble 30 is of the same shape as the thimbles 14. The threaded arbor ends 56 are passed through spaced apertures or tube seats 12 and connected to hydraulic jacks 62, which pull the tube panel towards the drum. The panel is manipulated, if necessary, to align the thimbles 14, 30 with the tube seats and the jacks then actuated again to draw the tube panel into position. The thimbles 14, 30, jacking means 62 and mandrels 22 are then removed and the tube end portions secured in position.

Title: Speed-control system for road traffic
Inventor: LOWE BENJAMIN
IPC: G05D13/00
Filed: 1965-11-20
Abstract: 1,147,459. Controlling vehicles. B. LOWE, and P. A. LOWE. 11 Oct., 1966 [20 Nov., 1965], No. 49396/65. Heading B7H. [Also in Division H4] In a speed-control system for road traffic, each vehicle is provided with means which in response to the reception of a specific radio signal, automatically reduces the speed of the vehicle to a predetermined maximum value by applying the brakes and simultaneously reducing the power output of the engine. A pump 1 is driven whenever the vehicle is in motion, the suction side of the pump being connected to a fluid reservoir 3 and the delivery side to a master cylinder 5 containing a free piston 6. Piston 6 is forced back by the fluid pressure until a rotary outlet valve 7 controlling return line 9 is exposed so that no further movement of the piston occurs. A governor 10 is driven with the pump 1 and controls a rocking lever 12 carrying a switch contact 13 co-operating with a contact 17 mounted on the armature 14 of a solenoid 15, the lever 12 being pivoted on the armature 14. The valve 7 is controlled by a second solenoid 20. Under normal conditions of driving the vehicle contacts 13, 17 remain open but when a predetermined radio signal is received at 22 solenoid 15 is energized causing an incremental retraction of the armature, the reception of further different signals causing corresponding retractions until the contacts 13, 17 are closed. This energizes solenoid 20 to close valve 7 so that pressure on piston 6 builds up to a maximum as determined by relief valve 23 and operates a piston 27 in a slave cylinder 26. The piston 27 is coupled to the accelerator pedal 29 and after a predetermined travel uncovers a port 30 allowing pressure fluid to be applied via pipe 31 to the braking system. The radio signals are transmitted from a plurality of stations situated at regular intervals along the road, each receiver providing a signal to operate a warning device immediately it comes within effective range of a transmitter and the driver being expected to reduce speed accordingly. When the receiver reaches the immediate vicinity of a transmitter the solenoid 15 is energized but if the driver has already responded to the warning, the contacts 13, 17 will remain open due to the lowered position of the sleeve 11. Otherwise the speed will be reduced as described until the response of the governor allows contacts 13, 17 to separate. Different signals can cause the vehicle speeds to be reduced step by step until, if desired, all traffic is stopped.
