Patent GB-1070052-A (GB)
Title: Improvements in or relating to presses
Inventor: BURR WILLIAM THOMAS
IPC: B21D28/16
Filed: 1965-03-03
Abstract: 1,070,052. Punching. FINE-BLANKING Ltd. March 2, 1966 [March 3, 1965], No. 9052/65. Heading B3W. In a fine-blanking press the work-material is pressed against the die by a gripper device A which has a V-shaped rib which bites into the work-material at a small distance from the periphery of the punch 11, and to prevent undue wear on the punch the pressure on the V-shaped rib is released before the punch is withdrawn from the work-material. The punch is mounted on an hydraulicallyoperated ram 10 on which there is also mounted a gripper carrier 12 which includes an annular piston 16. The piston 16 slides in a cylinder 17 formed in the gripping carrier 13, which can move axially relative to the ram and punch to an extent limited by slide members 15. The cylinder 17 is connected through a valve 21 to a source 24 of high pressure hydraulic fluid. The shuttle of the valve 21 is pressed in one direction by a spring 27 and is moved against the spring by pressure fluid from a duct 34. A solenoidoperated valve 32 controls the fluid from the duct 34 and the solenoid of-the valve is actuated when a switch 41 is closed by a projection 45 on the press ram. Operation.-As the ram descends the V-shaped rib is first pressed against the work material and fluid is displaced from the cylinder 17 through the valve 21 to the pressure source 24. The projection 45 then releases the lever 44 of the switch 41, the switch opens and the solenoid valve 32 closes and allows the valve 21 to move to the closed position. As the ram completes its movement the V-shaped rib is pressed firmly against the work-material and the -punch operates. When the ram moves upwards the punch lifts the work-material and the gripping device 13 with it and when the work-material has been raised above the die a distance greater than the thickness of the material the projection 45 closes the switch 41 which energizes the valve and allows pressure fluid from the duct 34 to open the valve 21. Pressure fluid from the source 24 then enters the cylinder 17, pushes down the gripping device 13 and strips the work-material off the punch.

Title: Improvements in carriages for supporting tongs employed in drilling wells or the like
IPC: E21B19/16
Filed: 1925-04-06
Abstract: 250,752. Smith, N. K. April 6, 1925. Borehole apparatus.-A rotary carriage for boring wells comprises a base-plate carrying a flanged post 60 on which is mounted a sleeve 62 provided with jaw mechanism to grip one arm 51 of a pipe tongs. The sleeve 62 is slidable vertically on the front and rests on a spring 63. A housing 69, bolted over an offset portion of the sleeve, is provided with jaws forming a slot 74, and with an eccentric pin 76 fitting between two discs 75 which are rotated in the jaws by a lever handle, so that when one arm 51 of the pipe tongs is inserted in the slot, the pin 76 is forced into a notch in the arm 51 which is thereby held in position. To prevent the pin 75 from working loose, a pivoted latch 83 is swung down so that its stop 84 abuts against the handle 78 and holds its firmly. When the tongs are to be used in the reverse position in the jaw slot 74, the latch 83 is hinged over the other lug 80 so as to bear against the other side of the lever 78. Specification 250,864 is referred to.

Filed: 1929-03-25
Abstract: 322,979. Kottmair, E. March 25, 1929. Clutches, claw; operating clutches. - An appliance for displaying carpets &c. and of the kind having horizontal carrier arms radiating from a shaft and automatically moved about the shaft, has the shaft driven n through a friction coupling and clutches successively to the carrier arms. A motor 4 drives a worm wheel 3, the upper surface of which forms one member of a friction coupling, the other member 2 being secured to a vertical shaft 1. The shaft is connected by gearing, such as worm gearing 24, to the rotary arm 14 of a multiple switch 13. The battery 17 is connected through an adjustable segmental switch 15 to the shaft and through the switch 13 and leads L to the spring contacts 9 of electromagnetic clutches 5, Fig. 5, mounted on the shaft 1, the armature 7 of which have a tooth 7<1> adapted to engage a notch in the rim of the clutch. The armatures carry the display arms 6 for the carpets &c., struts 11 resting on collars on the shaft being provided. In operation, as the shaft rotates, the rotary arm 14 contacts with the studs of the switch 13 in succession, the period of contact being sufficient to complete the rotation of the corresponding display arm during its display movement. When all the arms have been operated, a reversing switch causes a reversal of the movement. Owing to the frictional drive, any display arm can be held stationary for examination.

In a compressed air brake system for railway vehicles of the kind described in Specification 745,105, wherein an indication is given to the driver when a train approaches an adverse signal, and in which automatic application of the brakes is made at the end of a predetermined interval after the giving of the indication, if the driver does not acknowledge the indication within that interval by operating a cancelling lever, the re-energization of a normally energized electric circuit, which enables the brakes to be released after being thus applied, is arranged to be automatically delayed for a predetermined interval of time. This form of operation is provided by a switch device 8 controlled by a piston having the space 41 above it at the brake pipe pressure in the pipe 22 leading to the emergency application valve 7 and the space 42 below it in connection with a timing reservoir 9 and with pipe 22 by a restriction 35. When the emergency valve 7 is opened, it connects pipe 22 to atmosphere so that due to restriction 35 a pressure differential is created across the piston 38 which tends to maintain the switch 36 open for a predetermined period long enough to permit the train to come to a stop.

Title: Improvements in and relating to the lining and coating of metal pipes
IPC: B05D7/22
Filed: 1937-04-07
Abstract: A method of lining and coating a pipe with asphaltic material, consists in closing the pipe, heated to a suitable temperature, introducing a predetermined amount of thinly liquid asphalt thereinto, slowly rotating the pipe with its axis substantially horizontal, and helically winding a strip of thickly liquid asphalt around it.  According to an example, the pipe is heated to 150--160 DEG  C. and closed by ring dams.  Coal-tar pitch or a similar asphaltic material, heated to the same temperature, is poured into the pipe, which is then set up with its axis disposed horizontally and is rotated at a circumferential speed of 0.5--1 meter per second. Simultaneously, rather viscous blown asphalt bitumen, heated to 150 DEG  C., is run on to the exterior of the pipe, from an axially - moving receptacle.  Air or water cooling may be applied.  A protecting strip of paper or other fibrous material may then be helically wound around the pipe, and secured thereto by a very thin layer of asphalt.  According to the Specification as open to inspection under Sect. 91, the lining and coating materials have substantially equal hardnesses at 25 DEG  C., but at 150 DEG  C. the viscosity of the coating material is about thrice that of the lining material.  This subject-matter does not appear in the Specification as accepted.
