Title: Improvements in or relating to steering devices more particularly as used in aircraft
IPC: B64C13/00
Filed: 1946-08-29
Abstract: 644,355. Controlling aircraft. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-EST. Aug. 29, 1946, No. 26014. Convention date, Jan. 16. [Class 4] An aircraft control system, wherein manual operation of a relatively small control surface to give the pilot a sense of " feel " causes operation of an electric servomotor to operate a main control surface, is modified by controlling the speed of operation of the servomotor in accordance with the air pressure on the pilot surface to prevent too rapid operation of the motor. As shown, actuation of the primary member 40, of a follow-up switch, by the control lever 1, energizes relay 60 or 61 to drive the servomotor 7 in one direction or the other, the speed of operation being governed by a rheostat 55 controlled by a dynamometer system (not shown) measuring the stress applied to the pilot surface (not shown) by the control lever. In a modification, Fig. 5 (not shown) the followup switch controls the motor direct. The rheostat 55 may be operated in steps. Specification 25849/46, as open to inspection under Sect. 91, is referred to. The Specification as open to inspection under Sect. 91 states that the servomotor may be electric or hydraulic. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electric circuit arrangements for transferring information from several information processing systems working in parallel to one or more receivers
IPC: G06F11/18
Filed: 1965-06-21
Abstract: 1,092,832. Data switching. SIEMENS A.G. June 21, 1965 [June 22, 1964], No. 26067/65. Heading H3T. [Also in Division G4] A plurality of data sources is connected to one or more receivers via coincidence circuits equal in number to the data sources, so that each coincidence circuit receives an input from each data source and the receiver(s) is energized only when all the data sources have identical outputs. In Fig. 2 each coincidence circuit comprises transformers U1, U2 . . . Un with their secondaries in series and their primaries energized by signals from the data sources S DVAI , S DVAII  . . . S DVAn . Only if all the primaries are energized will the secondary voltage be sufficient to break down Zener diode D z  and allow transistor T M  to conduct. If one input fails, the system can be brought into use by applying a signal to an auxiliary winding of the appropriate transformer in one of the coincidence circuits, e.g. at S 1DVA1 . In a modification (Fig. 3, not shown) there is only one transformer in each coincidence circuit and the various data inputs are supplied in parallel to its primary via separate resistors. The emergency signal is also supplied in parallel with these via a resistor whose conductance is equal to the sum of the conductances of the other resistors. In another modification of Fig. 2 (Fig. 4, not shown) each data input is applied to the primary windings of the transformers in the different coincidence circuits via isolating resistors and diodes. To protect the transformers against short-circuits in the input lines a part or all of the input resistance is provided by the windings themselves and each secondary is shunted by a Zener diode and an isolating diode in series, the latter diode blocking the positive voltage peak to allow the secondary voltage to decay faster. The emergency signal is tapped into the corresponding transformer at a suitable point. To operate a number of receivers selectively from two data inputs (Fig. 5) a co-ordinate matrix is provided with the X1, X2, X3 terminals of the DVAI system shown connected to the x1 x2, x3 terminals of the DVAII system (not shown); the Y1, Y2, Y3 terminals are similarly joined to the yl, y2, y3 terminals. To energize the output I1 in the sub-unit M11 the terminals Sx 1  and Sy 1  are energized so that current flows through the corresponding rectifier D E , resistor Rv/2, terminal x1, terminal X1, transformer U2 and transformer U1.- The various diodes D M  isolate the transformers in the different sub-units from one another. For more than two data inputs these are applied to coincidence circuits in pairs to give a majority logic decision as long as two inputs remain energized.

Abstract: 601,084. Fluid-actuated valves. PEET, A. Oct. 12, 1945, No. 26793. [Class 135] [Also in Group XIII] - In a gas-fired water heater having a self-closing gas valve 26 opened automatically by a pressure-responsive member 6 when water flows through the heater pipe 9, the gas valve casing 30 has two opposite inlet passages 30a, 30b, either of which may be sealed off with a closing plate 24, whilst the other of the inlet passages is connected to the outlet of the main gas tap 21 so that the latter may be located on either side of the casing 30. The heater pipe 9 is connected to a hot water conduit 15 having end connections 15a, 15b disposed on opposite sides of the casing 30, one of these connections being closed by a sealing element 15c and the other being connected to a hot water outlet tap 17 so that the latter may be located on either side of the casing 30 and on the opposite side to the gas tap 21. The tap 17 communicates with an outlet branch 17b to which is detachably coupled an outlet spout 18. A second outlet branch 33 connected to the hot water conduit 15 is closed by a sealing element (not shown) when the heater is used to supply a bath, sink, wash basin or the like. When, however, the heater delivers to a multipoint hot water system, the spout 18 is detached and the branch 17b closed by a sealing element whilst the branch 33 which communicates directly with the conduit 15 and the heater pipe 9 by aT-piece 14, 14a is connected to the multi-point system. Alternatively, the complete water tap 17 may be detached and the other end connection 15a or 15b closed by a sealing plug. The main gas tap 21 may be operated through link or other mechanism by a centrally disposed control handle rotatably mounted on the casing 30, for example on a cover 28 holding the gas valve spring 27 in place. The pressure-responsive member 6 which may be either a piston or a diaphragm operates the gas valve 26 through a plunger 26a, and is located in a casing 13 bolted to the casing 30. The opposite sides 7, 7a of the diaphragm 6 are respectively connected to the water supply passage 3 and the throat of a venturi section 5, Fig. 6, mounted in the casing 13 between the passage 3 and the heater pipe 9. The latter connection is controlled by a hollow ported screwed plug 8 containing a ball valve 34 to check any sudden rush of water from the chamber 7a when the plug is closed on the seat 12c. A pipe 31 leads from the main gas tap,21 to a pilot jet adjacent the main burner 29.
