IPC: H01G13/06
Filed: 1955-08-08
Abstract: In a method of applying a metal-containing coating solution or paint to solid dielectrics such as mica or ceramic plates, the paint is first spread on the surface of a thin base or carrier sheet, for example of synthetic plastic material or regenerated cellulose, which may first be coated with a release layer, e.g. paraffin wax, and allowed to dry, the base sheet is placed against the dielectric paint-side on, and a heated die is pressed against the back of the base sheet so as to cause the paint under the die to transfer to the dielectric surface.  The paint may be applied to the whole surface of the carrier and the die may determine the size and shape of the coating applied to the dielectric, or the paint may be applied only to selected areas of the carrier, which areas are then positioned against portions of dielectric to be coated and a large die used to transfer coatings to several portions simultaneously.  The coatings may subsequently be fired. Two coatings may be applied to form a silver layer, the first having a high volatile content and a low silver content, the second having a high silver content.  A suitable synthetic plastic for the carrier sheet is polyethylene terephthalate.

Abstract: 1,148,853. Anti-collision apparatus. SOCIETE DES FORGES ET ATELIERS DU CREUSOT. 17 May, 1967 [26 May, 1966], No. 22947/67. Heading B7N. Anti-collision apparatus for use with two vehicles on the same track comprises for each of the two directions of travel of each vehicle M 1 , M 2  a decelerating mechanism 1, 2; 3, 4, respectively, each mechanism, e.g. mechanism 1, comprising a differential having a first sunwheel 10 retained resiliently by a spring 15 through a rack and gear wheel 14, 13; a second sun-wheel 5 driven by an element 6 representing the position of the vehicle with which the mechism is associated; and a differential cage 8 having a lever 16 attached thereto wherein a cam 11 connected with the first sun-wheel is rotated against spring 15 to operate a decelerating rheostat R 1  when lever 16 contacts an abutment 17. The mechanisms 2, and 3 are associated with the directions of the vehicles when they are approaching each other and have their abutments 18, and 19 fixed to gears 20, and 21 which are driven by the elements 6 associated with the other vehicle. The abutments associated with mechanisms 1, and 4 have fixed abutments. When vehicle M 2  is stationary and M 1  moving towards it abutment 18 associated with the movement of vehicle M 2  is stationary and indicates the position of their vehicle. When vehicle M 1  is accelerating or remaining at a constant speed cam 25 and sun-wheel 26 are stationary and cage 27 rotating with lever 28 moving towards abutment 18. When vehicle M 1  reaches a distance Y metres from vehicle M 2  lever 28 abuts 18 so that rheostat R 2  is operated and decelerates vehicle M 1 . In the case where the vehicles are moving towards each other the movement and position of vehicle M 1  is represented by the movement and position of lever 28 and similarly for vehicle M 2  by abutment 18. When the vehicles are distance X metres apart the lever 28 has its direction of movement reversed by lever 18 with the result that rheostat R 2  is operated to slow vehicle M 1 . Similarly rheostat R 3  of vehicle M 2  is operated when the distance between the vehicles is Y metres. When the vehicles are approaching each other brakes 24 associated with the differential cages also operate. When the vehicles move in the same direction with the pursuing vehicle M 1  travelling the fastest abutment 18 and lever 28 represent the movement and position of the vehicles. When the distance between the vehicles is X metres lever 28 has caught up with the abutment 18 and the rheostat R 2  is operated to slow down vehicle M 1 . If a vehicle approaches buffers at the end of the track then at a distance X or Y therefrom depending on the vehicle the lever associated with the mechanism of that vehicle direction will contact fixed abutment 17 or 33 to operate rheostat R 1  or R 4 .

In one form, the drum is mounted in bearings in the shaft 1, and has longitudinal bars 7 connecting its complete end walls. A worm 10 rotates in a feed channel 8, of which the wall 11 on the rising side of the worm is recessed, so that the material is shaken out of the channel and falls into the drum. A valve 13 blocks the channel 12 and directs the hot gases through the material. In another form, the bars are tapered outwardly, and the feed channel lies withinthe drum. In this case, the material leaves the channel through apertures which are made bigger and approach nearer to the bottom of the channel on passing from the inlet end. The drum may be emptied more rapidly by reversing the rotation of the drum while opening the side gas passage and closing the main passage. The alteration of the speed or direction of rotation of the drum may be automatically controlled. The interior of the drum may be provided with heat exchanging bodies such as balls, tube sections, or chain ends.
