Title: Improvements in and relating to strip feeding apparatus
Inventor: SCHNEIDER KURT RUDOLF
IPC: B65H20/04
Filed: 1960-10-18
Abstract: 939,401. Feeding webs. EUREKA SPECIALTY PRINTING CO. Oct. 18, 1960, No. 35606/60. Class 100 (1). Strip S, Fig. 2, is supplied from a roll R to a reciprocating shuttle H which engages apertures in the strip to feed the strip to a machine D, e.g. a label applying machine. The machine D has an arm 12 carrying a spindle 13 rotatably supporting a disc 15, Fig. 3, carrying a rocker member 16. The member 16 has an arcuate extension, Fig. 2, having a frictional surface 17 for engagement with the strip. The member 16 has a freely rotatable roller 20 forming a loop in the strip as it is unwound from the roll R. A spring 23 urges the member in a counterclockwise direction. During feeding movement of the shuttle H, strip is pulled past a roller 25 thereby lifting a roller 31. The strip causes the member 16 to be swung, by frictional engagement with the surface 17, towards the machine D, the strip sliding along the surface during such movement of the member 16. The roll R rotates slowly to unwind strip, thereby obviating the risk of tearing the strip. The roller 20 moves counterclockwise to form a strip loop, under the action of spring 23, during the return stroke of the shuttle H. Retrograde movement of the strip is prevented by the roller 31 dropping to press the strip against the roller 25. The roll R is mounted on a sleeve 36, Fig. 3, and is braked by a friction head 40 readily detachable for replacement of the roll R.

Title: Steam power plants employing forced flow steam generators
IPC: F01K7/22
Filed: 1954-12-10
Abstract: 757,293. Steam turbine plant. SULZER FRERES SOC ANON. Dec. 10, 1954 [Dec. 10, 1953], No. 35769/54. Class 110(3) In a steam power plant comprising a forced flow steam generator working at a pressure of the order of 150 atmospheres or above feeding steam to a turbine having high, intermediate and low pressure turbines with reheaters between the high and intermediate pressure and the intermediate and low pressure turbines, the reheaters being heated by steam before it enters the high pressure turbine, has the heating steam sides of the reheaters connected in parallel to common steam supply and return pipes. The condensate pump 2 draws condensate from the condenser 1 and delivers it through feed water heaters 4, 5, 6 into the feed tank 7. A feed pump 8 draws water from the tank 7 and delivers it through feedwater heaters 10,. 11, 12 to the steam generator 13. The steam leaving the superheater 14 flows through pipe 15 to pipes 16, 17 leading to the reheaters 18, 19. The first ports 18a and 19a i.e. those subject to high temperatures of the reaheaters are made of austenitic steel and later' ports 18b 19b of ferretic steel. After leaving the reheaters the steam is re-united in a conduit 20 through which the steam flows into the second superheater 21 and thence through a. steam valve 22, a valve 24 and a quick acting stop valve 25 to the high pressure turbine 26. After partial expansion in the turbine 26, the steam is reheated in the reheater 18 and then passes through valve 28 to the intermediate pressure turbine 29. After further expansion in the turbine 29, the steam is reheated in the reheater 19 and expanded in the turbine 32 which exhausts to the condenser 1. Steam is bled from the turbines by means of the pipes 35 and led to the feed water heaters 4, 5, 6, 10, 11, 12 and the feed tank 7. The drains from the heaters 10, 11, 12 are led back to the feed tank and those from the heaters 4, 5, 6 back to the condensers. To adjust the temperature of the reheated steam by-pass pipes 38, 39 with control valves 40, 41 are provided. A valve 42 is also provided in the return from the reheater 19 to control the division of steam between the reheaters. In order to accelerate the starting process, a turbine by-pass 44 together with a control valve 43 is also provided. The invention is based on the fact that the specific heat of steam rises with in-- crease fo pressure and temperature to a maximum value and then falls off again. It is thus possible to reheat to the desired extent the whole of the partially expanded steam with a smaller quantity of high pressure steam.
