Title: Improvements in ships' engine-room telegraphs and like follow-up signal indicators
IPC: G08B9/08
Filed: 1950-07-03
Abstract: 667,958. Order-telegraph signalling apparatus. BUTLER, E. F. July 3, 1950. No. 16579/50. Class 118 (ii). In a ship or like telegraph system employing instruments connected by balanced closed hydraulic circuits, each halves of each circuit is connected to a fluid reservoir through a positive and negative pressure-sensitive valve such that fluid may escape to the reservoir on occurrence of an excess pressure whilst fluid may enter therefrom to avoid evacuation in the circuit. In the bridge instrument, Fig. 1, the operating handle rotates a shaft 15. carrying a toothed wheel 19 and thereby displaces a piston 7 in cylinder 5 the ends ofwhich are connected through pipes 42, 43 to the ends of a similar cylinder with a piston operating a pointer in the engine instrument, Fig. 3 (not shown). The ends of cylinder 5 are connected to a reservoir of fluid 46 through valves 55, 56. In these valves, Fig. 5, a valve member 73 lifts on occurrence of excess pressure in the hydraulic circuit connected at 71 allowing excess fluid to pass into the reservoir whilst a reduction of pressure below that in the reservoir causes valve member 75 to open to admit more fluid to the circuit. Pipe 48 leads from the reservoir to a pump 49 connected through a valve 52 to pipes 42, 43. In the engine instrument the ends of the cylinder are joined through a valve which may be opened to balance the pressure in each half of the circuit. Valves are also provided for bleeding off air from the system. A screen 77 (Fig. 5) in the pressure-sensitive valves is provided to displace member 75 when it is desired to do this. A modified system, Figs. 6 and 7 (not shown), employs pairs of single-ended cylinders in place of the double-ended cylinders.

Title: Improvements in electromagnetic wave signalling systems
IPC: H01Q9/04
Filed: 1921-06-16
Abstract: 165,038. Mauborgne, J. O., and Hill, G. June 16, 1920, [Convention date]. Aerials; coupling oscillating and radiating circuits; directive signalling; multiplex signalling; transmitting systems and apparatus.-The transmitting-aerial consists of an ungrounded coil of closely-wound insulated wire, preferably formed on a core of insulating material, whereby the inductance, capacity, and resistance are uniformly distributed so that energy applied from any suitable source is radiated equally from each element of the coil. The wave-length emitted is determined by the electrical characteristics of the coil and by the location of the point P of applied potential. Or the energy may be applied at a fixed point, and the effective length of the coil adjusted until its natural wave-length corresponds with that of the source. If the point P is central, two equal waves are radiated; as it is moved towards one end of the coil, one shorter and one longer wave are emitted, until, when the point P is at the extremity of the coil, a single wave is again radiated having double the length of that given out when the point P is at the centre. Multiplex working may be effected in this manner Such an aerial is stated to have strongly directive properties, the direction of emission being perpendicular to the longitudinal axis of the coil. As shown in Fig. 3, high-frequency oscillations from a thermionic generator V are applied to the aerial A by a slider P which makes direct metallic contact therewith. No earth lead is necessary. A spark-gap or are source may be similarly connected. As shown in Fig. 6, a tuned circuit C1, R across a spark-gap S is inductively coupled to the coil-aerial. The electromagnetic coupling R can be adjusted to any point along the aerial. Alternatively, the coupling with the aerial may be electrostatic. Fig. 8 shows an arrangement in which two coil-aerials are separately excited one from each side of a spark-gap S; or both coils may be connected to one side of the source S. The use of several such aerials in parallel provides an efficient means of transmission with considerable power on very short wave-lengths. In the arrangement shown in Fig. 10, an earth lead G is employed, which under certain conditions is stated to give an increased efficiency at the expense of some loss in the directional effects. In Fig. 11, the second slider Q may be connected to a radiating antenna, or to a distant receiving station for wired-wireless work; or it may be earthed. Curved or arc-shaped aerials, wound upon a flexible rubber core, may be used if it is desired to radiate energy in various directions simultaneously. The high-frequency oscillations applied to the coil-aerial may be modulated for speech transmission.

Abstract: 947, 525. Electric correspondence control systems. DAVY & UNITED INSTRUMENTS Ltd. May 4,1962 [May 8,1961],No. 16605/61. Heading G1N. The thickness of the strip 20 in a rolling mill 12 is determined manually by the setting of a potentiometer 26, producing a signal which is compared with that from a controlled potentiometer 24, and a load cell 23,the difference voltage E 1  being modified by the removal of harmonics produced by roll and bearing eccentricity to give an error voltage E o  controlling the screwdown motor 22 and/or the tensioning motors 16,18. The difference signal E 1  is fed via brush 33 to a commutator 34, rotating synchronously with the rolls 14, which has a capacitor 36 connected between each segment 37 and a common earth point. Thus, one complete cycle of voltage E 1  is distributed over the commutator segments, and a second brush 38 nicks off a voltage E 2  180 degrees out of phase with E 1 , which is added to E 1  at 32 to produce signal E 3 , thereby eliminating the odd harmonics of the eccentricity component in E 1 . The signal E3 is fed into the commutator 34 at a brush 40 and a voltage E 4 , taken off 90 degrees by brush 41, is added to E 3 , thereby eliminating the even harmonics.

Abstract: 529,746. Combing-machines. NASMITH, J. W. June 7, 1939, No. 16665. [Class 120 (i)] In a combing-machine of the rectilinear type having a pair of detaching rollers the lower one of which is positively driven and geared to the upper roller, the gearing of this upper roller is slidably but non-rotatably mounted on the shaft and is held against axial displacement when in position by the usual weight hook which has necessarily to be removed when it is desired to remove the upper roller; when the weight hook is removed the gearing of the upper roller can be easily slid therefrom. As shown the gear 12 meshing with the gear 6 on the lower fluted roller 5 is connected to the shaft of the upper roller 7 by a pin 13 extending tranversely across the gear and engaging the slotted end 11 of the shaft; an extension 9a of the usual weight hook 9 prevents axial displacement of the gear 12. In a modification the gear is freely mounted on the shaft of the upper roller and is driven thereby through a disc rearwardly fixed to the gear and having a flat-sided aperture engaging flat portions of the shaft.
