Abstract: 1,212,690. Converting. GENERAL ELECTRIC CO. 12 Dec., 1967 [30 Dec., 1966], No. 56474/67. Heading H2F. In a cyclo converter for converting polyphase A.C. of one frequency to a lower frequency, the converting elements are connected in groups to interphase transformers 38, 39 the elements of successive phases being arranged in different groups. In a 6-phase embodiment, Fig. 1, each phase is connected to two rectifiers and the rectifiers are grouped together into four groups A.B.C.D. Each pair of groups A, B and C, D are interconnected by transformers 38, 39 and the common point of each transformer is connected to a filter 23, 24. In a 9-phase embodiment, Fig. 3 (not shown), the rectifiers are arranged in two sets, each set containing three groups interconnected by a three phase star transformer. The two star points are connected to the output filter. A twelve phase source may be interconnected in a similar manner, Fig. 5 (not shown), each group having four rectifiers instead of three. In an alternative 12-phase arrangement Fig. 4 (not shown), the elements are arranged in eight groups. Pairs of groups are connected to transformers, as on the 6-phase version, and the centre points of these transformers are connected to two further transformers whose centre points are in turn connected to the output filter. Fig. 6 shows a complete system for producing a three phase output of constant frequency from a variable frequency input 106, and comprising three cyclo converters 101A, 101B, 101C. Control signals from the converting elements are produced by adding suitable phased signals from an auxilliary oscillator 111, firing pulses derived from the input source 106, and a feedback signal from units 103A, 103B, 103C. The auxilliary oscillator is a stable oscillator operating at a multiple of the required output fre. quency, and the control pulses are obtained by frequency division.

In an aircraft mounted Omega system (Registered Trade Mark) the latitude # and longitude # are given by: # = # 0  + a 1 (Dxy) + a 2 (Dpq) + a 3 (Dxy)(Dpq) + a 4 (Dxy)<SP>2</SP> + a 5 (Dpq)<SP>2</SP>. # = # 0  + b 1 (Dxy) + b 2 (Dpq) + b 3 (Dxy)(Dpq) + b 4 (Dxy)<SP>2</SP> + b 5 (Dpg)<SP>2</SP>, where Dxy = Wxy-Wxyo, Dpq = Wpq - Wpqo and Wxy, Wpq are the hyperbolic co-ordinates of the receiver, and Wxyo, Wpqo, are the hyperbolic co-ordinates of a fixed reference point. The different sets of constants a 1 -a 5 , b 1 -b 5 , relating to different regions are stored and selected either by logic elements detecting the hyperbolic co-ordinates from the receiver or the most recent latitude and longitude readings. The relevant set is read, with the hyperbolic co-ords into a computer which calculates and displays the latitude and longitude of the receiver (Figs. 2, 4, not shown). Alternatively, the co-ordinates may be selected by choosing a punched card or tape from a set thereof and feeding it into a reader connected to the computer (Fig. 3, not shown). The contacts a 1 -a 5 , b 1 -b 5  are found by calculating the hyperbolic co-ordinates of five points of known latitude and longitude in a particular region and solving the resulting simultaneous equations. The Specification discloses a computer programme for so doing.

An arrangement for displaying movable signs to sub-divide a totalized number in a calculating machine, comprises a first row of windows c, Fig. 1, for displaying the subdividing signs and a second row of windows b for displaying the totalized number, the two rows of windows being arranged adjacent to each other with the windows c on axes between those of the windows b. Behind the first row of windows c is a cylinder d having two or more helically arranged markings h, h<SP>1</SP>, h<SP>2</SP> of a pitch such that on rotating the cylinder d coloured marks appear successively in the various windows c of this first row. Thus, in Fig. 1, the coloured marks may be moved to the left or to the right by a suitable rotation of the cylinder d but each pair of visible marks will always be spaced apart by two unmarked windows. By using suitably marked interchangeable cylinders, the number of unmarked windows between each pair of visible marks may be arranged to have any desired value. Instead of using interchangeable cylinders for this purpose, a single cylinder may be used marked with a number of helically arranged spots i, k, l, m, n, o, as shown on the developed cylinder surface in Fig. 3, the cylinder being longitudinally displaceable to any one of a number of working positions. In the different axial settings of the cylinder, the arrangement shown in Fig. 3 allows the unmarked windows c<SP>1</SP> between marked ones to be varied as is shown in Figs. 4, 5 and 6. The helical markings may have different colours. The Specification as open to inspection under Sect. 91, comprises also a ball catch on the machine co-operating with grooves on the axially displaceable cylinder to hold it in its working position. This subject-matter does not appear in the Specification as accepted.

Title: Working systems for welding of plastics
IPC: B29C65/04
Filed: 1978-07-10
Abstract: The invention refers to working systems for the welding of plastics sheet material, as well as laminates, particularly conveyor belts by means of high frequency current. According to the invention the high frequency generator is placed directly on the plastics material to be welded and its metal casing provides one of the elements of the working system and coupling thereof with the bottom electrode takes place either by the capacitance of the plastics material to be welded or through direct electric connection. For the joining of sheets of large area, a first sheet is spread over a metal plate which forms the bottom electrode and a second sheet is overlapped with the first foil along edge zones and the welding operation is carried out by shifting the welder over and along the plate. The direct electric connection is used for welding of comparatively narrow materials such as conveyor belts used in collieries, factories etc. For this operation the conveyor belt ends to be welded are girded with a metal foil and then put onto a metal plate which presents the bottom electrode, and subsequently the high frequency generator is put directly on the foil and the welding operations begins. <IMAGE>
