IPC: F01D9/02
Filed: 1925-06-30
Abstract: 236,926. Akt.-Ges. der Maschinenfabriken Escher, Wyss, et Cie. July 8, 1924, [Convention date]. Blades and nozzles. - In turbine diaphragms the inner and outer boundary walls of the guide passages are constructed, at least in the vicinity of the outlet, as single sheet hyperboloids the generatrices of which are prescribed straight line paths of flow. Figs. 1 - - 4 show guide channels bounded by such a surface 1, the blades 2 being cut out of a solid ring 3. The generatrices of the asymplotic cone of the hyperboloid form with the parallel circle passing through the apex of the sheet an angle a which is equal to the angle of outlet of the guide passages. The outer boundary wall of the guide passages is not shown in Figs. 1 - - 4, but is also constructed as a single sheet hyperboloid, and the blades may be formed integrally with this wall instead of with the inner wall. The shaped inner and outer walls may be formed by distance pieces 6, 7, Fig. 8, which hold fast the blades 8. The blades 8 may be welded to the pieces 7, and an enclosing ring may be dispensed with. The outlets from the guide passages may be arranged to right or left of the X-X axis of the hyperboloids: Fig. 10 shows the outlet 12 to the left, while Fig. 12 shows an oblique outlet 21. The inlet portions of the guide passages may be bounded by cylindrical surfaces 24, Fig. 14, the outlet portions 22, 23 being single sheet hyperboloids as before.

Title: Digital direction transmitter, especially for cranecontrolling apparatus
IPC: H03K5/26
Filed: 1965-04-21
Abstract: 1,074,500. Electric Selective Signalling. DEMAG-ZUG G.m.b.H. April 21, 1965 [Sept. 1, 1964], No. 16857/65. Heading G4H. In a digital direction transmitter, in which marks provided along a path to be measured are scanned, the marks giving pulses to a forward or backward output, these are two tracks each consisting of a sequence of marks, the marks of one track partially overlapping the marks of the other so that signal pair sequences 10, 11, 01 and 01, 11, 10 are produced for forward and backward movements. The circuit, Fig. 1 (not shown), comprises a flip-flop (B1 which is controlled by the track signals (A and B) through inverters (II-14) and gates (K1, K2) so that output (4) gives a signal following the (B) track during forward movement and following the (A) track during backward movement. The output (3) has signals the inverse of these, i.e. (B) for forward and (A) for backward motion. These signals are delayed and made into a short pulse by capacitor (C) and inverted (at 15) to set a flip-flop (B2), reset by (A, B) via gate (K2). The output of this is (B) for forward and (A) for backward. Gates (K5 and K6) receive the output (3) from (B2) and output (4) from (B1). The output (4) of flip-flop (B2) is gated with the (A) signal at (K3) and with the (B) signal at (K4). Flip-flop-(B4) produces (A, B) for forward motion on output (3) and for backward motion on output (4). These are also connected to gates (K5 and K6). A further flip-flop (B3) is set by (A) and reset by (B). Corresponding outputs (3 and 4) are applied to gates (K5 and K6). The outputs of gates (K5 and K6) are inverted to apply " forward " and " backward " pulses respectively to counter inputs (E and F). The simultaneous control of gates (K5 and K6) by flip-flops (B3 and B4) ensures that no miscounting takes place upon reversal of direction between marks. The outputs of (B4) control gates (K7, K8) also receiving a signal (D) indicating equality between the desired position and the actual position. The outputs (G and H) allow movement of the controlled member back to the desired position if this position has been overrun.

Abstract: 274,840. Electrolux, Ltd., (Assignees of Platen-Munters Refrigerating System Aktiebolag). July 26, 1926, [Convention date]. Refrigerating, absorption machines for.-Condensed refrigerant is led from the condenser 3 through a pipe 4 to a chamber 5 within or adjacent to the rectifier or water separator 2 so as to serve as a cooling-medium therefor by evaporation. Since the flow of refrigerant depends upon the activity of the generator the amount of cooling of the rectifier is adjusted automatically and over and under cooling are avoided. The chamber 5 is preferably conical and is provided with slotted gills 6, and the evaporated refrigerant escapes through holes 10 or an open top and flows back to the condenser with the main stream of vapour. The unevaporated refrigerant passes by a pipe 7, preferably extending through an interchanger 12, to the evaporator 8. The apparatus shown is one in which an inert gas such as hydro. gen is present in the evaporator 8 and absorber 11, and the cold gas mixture from the evaporator flows around pipes 15 of the interchanger 12 and enters the absorber 11 by a pipe 18. The unabsorbed hydrogen returns to the evaporator through the pipes 15 and a riser pipe 16. The pipe 7 and the condenser 3 are provided with vent pipes 22, 23, which may connect with the top of the evaporator or with the end chamber 13 of the interchanger, to allow any gases to pass to the gas circuit.
