1 While the pantograph is probably the simplest type of digitiser there is it is often completely adequate for home computer use.

2 In 1928 ten new Pullman cars, fitted with pantograph collectors instead of trolley poles, took over the Fleetwood service.

3 However there have been two periods of pantograph operation on a limited scale: from 1927-33 and again from 1974.

4 According to the work condition of pantograph slider, materials with improved friction wear performance was designed.

5 The resin - matrix pantograph contact strip ( RMPCS ) was prepared by using hot re - pressing and vacuum - impregnation process.

6 In this paper detailed introduction of pantograph slide materials and and international researches and development condition.

7 The study of this thesis is on the pantograph slider of locomotive,[] which is a typical example of the sliding electric contact theory.

8 The four - linkage tilting mechanism of pantograph is optimized to match the four - linkage tilting mechanism car body.

9 The species and preparation methods of carbonic system pantograph strip materials are explained in detail.

10 Successful design of the high speed pantographs requires computer simulation of the coupled catenary - pantograph system.

11 And common pantograph slider prepared by powder metallurgy technology usually causes serious abrasion of the conducting wire.

12 Pantograph slide is the pivotal parts of electric locomotive, which get power from power supply web.

13 The optimum geometric parameters, which could improve the pantograph performance , could be obtained successfully.

14 All the cars adopted this livery, and early in 1976 car 5 was fitted with a pantograph.

15 This fascinating picture shows a Motherwell car in Princess Street fitted with a pantograph in 1927 as an experiment.

16 A commercial postcard showing 173 at Bispham in its original colour scheme complete with pantograph. 2.

17 The purpose of catenary detection is to maintain its security and avoid the catenary - pantograph fault.

18 Therefore, how to obtain the smallest equivalent mass in the condition of certain strength and stiffness is the object that the pantograph designers shall pursue.

19 That using the graphite-based C/C complex material as the new material for high-speed rail vehicle pantograph slide bar is pointed out. What's more, the advantage and developing prospect is foreseen.

20 In view of the existing problems of current electric locomotive pantograph slide plates, a new panto- graph slide plate is developed by using powder metallurgy technology.

21 This paper presents the control strategy of type DSA250 pantograph on the electric control concept and pneumatic control concept about type KZ4A AC drive electric locomotive.

22 From the viewpoint of electric contact, copper base alloys have been applied to contact wires and also to pantograph sliders.
