Title: Device for digital control of a DC converter which is fitted with controllable rectifiers
Inventor: KALINICHENKO ANATOLY YAKOVLEVI
IPC: H02M1/084
Filed: 1978-03-07
Abstract: For digital control of the DC converter which is fitted, for example, with thyristors, input signals are transmitted from a control unit (8) via a matching unit (9) to a reversible counter (4) and to a control generator (6). The matching unit (9) has a mathematical sign flipflop circuit (26) and four AND gates (27, 28, 29, 30). The thyristors (18, 20, 22, 23) which are intended for controlling DC machines (49, 50; 52, 53) are connected by means of their control electrodes to a decoder (1) which is connected downstream of the matching unit (9), and to a pulse counter (2) which is connected downstream of the control generator (6). A switching unit (7), which has two flipflop elements (16, 17) and six AND gates (10, 11, 12, 13, 14, 15) is connected between the decoder (1) and the pulse counter (2) on the one hand and between the control electrodes of the thyristors on the other hand. Such a device, which is intended especially for controlling the rotation speed of DC machines in electric traction operation, allows the operating behaviour of the DC machines to be improved. <IMAGE>

Title: Filling machine for filling valve sacks
Inventor: COMBRINK ALOIS
IPC: B65B1/18
Filed: 1997-11-14
Abstract: The filling machine has a rotary driven rotor (1a) whose rotary drive beats intermittently, according to the number of filling tubes (13), so that, at least, the filled sack can be removed from the filling tube shock-free whilst the rotor is stationary. On the rotor, underneath the filling tubes, are intermediate conveyors (10) on which the valve sacks are supported for level transfer to the horizontal conveyor (22). The removal of the filled sacks from the filling tubes, and the transfer to the horizontal conveyor, is carried out by a sliding device movable in the longitudinal direction of each filling tube. In the vertical projection of each filling tube is a deflector plate for any filling material trickling out of the filling pipe. The deflector plate is likewise movable in the longitudinal direction of the filling pipe

Title: Process for the preparation of poly(sulphonyldiphenylene) phenylphosphonate
Inventor: URA YASUKAZU
IPC: C08G79/04
Filed: 1974-05-13
Abstract: The preparation is carried out by polycondensation of dihydroxydiphenyl sulphone and phenylphosphonyl dichloride in tetrachloroethane with or without a catalyst, where the viscosity of the resultant solution is reduced with respect to the overall solvent by addition of 0.1-25% of methanol, and the solution is introduced into a methanol bath in order to precipitate the poly(sulphonyldiphenylene) phenylphosphonate.

Abstract: The single-control tap is used to mix hot and cold water, and comprises three perforated plates made of a hard material, which can be displaced relative to one another in order to regulate the mixing ratios of hot and cold water, and the overall flow distributed. The first, lower, plate (11) is fixed, and is perforated by two inlet apertures (12,13), the second, intermediate, plate (15) rotates, and is also perforated by at least two through apertures, and the third, upper, plate (18) can be displaced linearly, substantially in the direction which connects the centres of the apertures of the intermediate plate (15), and also has at least two through apertures which cooperate with those of the intermediate plate (15). These arrangements mean that adjusting the mixing, which is obtained by rotating the second plate (15), and adjusting the flow, which is obtained by linear displacement of the third plate (18), can take place substantially independently of one another. <IMAGE>
