Steering-gear. - Relates to ships' Steering-gear worked by fluid pressure derived from a pump which is irreversible and provided with means for varying the delivery. The tiller arm is operated by two opposed rams to which pressure fluid is supplied by pipes 5, 6. A variable-stroke pump 9 is driven by an electric motor and delivers fluid through pipe 17 to spaces 19, 19<a>. The controlling-valve 10 is operated by a rod 24 through a lever 23 pivoted to the rams, so that pressure fluid may be supplied by either of the passages 21 to the pipes 5 or 6. The corresponding movement of the rams brings the valve 10 back to its neutral position. Spring-controlled safety-valves 22 are provided so that the fluid is by-passed in either direction if the pressure becomes too high. When the valve 10 is in neutral petition, the pressure produced in the space 19 forces the piston 12<a> to move back, thus varying the pump delivery. A hand-operated by-pass valve 7 may be provided which, when open, permits the rudder to be operated by hand

Filed: 1949-05-20
Abstract: 679,831. Emergency supply systems. STANDARD TELEPHONES & CABLES, Ltd. May 12, 1950 20, 1949; June 15, 1949], Nos. 13520/49 and 15967/19. Class 38 (iv). An alternator for continuously supplying a load is normally driven by a mains-fed A.C. or D.C. motor through a free-wheel clutch which, upon failure of the mains and consequent slowing of the motor, slips and actuates contacts (within the clutch) for bringing into operation stand-by means for driving the alternator and, preferably, also means for isolating the motor from the faulty mains. In the arrangement shown in Fig. 3 the stand-by means is a D.C. source which, upon slipping of the clutch, drives a D.C. motor coupled to the same shaft as the alternator. A fly-wheel maintains the alternator speed during changeover. In the modified system of Fig. 6, the stand-by means is an engine which is started, upon slipping of the free-wheel clutch, by energization of a magnetic clutch for coupling the alternator and engine together. The engine subsequently drives the alternator. To accelerate change-over, the motor may be braked upon mains failure. Specification 656,787 is referred to.

Title: Improvements in or relating to drawing synthetic textile filaments
Inventor: ANSCOMBE WALTER JOHN
IPC: D02J1/22
Filed: 1955-05-11
Abstract: The apparatus for drawing artificial filaments of the parent Specification which comprises a feed roll and a draw roll of larger diameter fixed on a common shaft, said rolls being provided with auxiliary separator rolls, and a nonrotatable snubbing pin, positioned so that the filaments pass in succession a plurality of times round the feed roll with its auxiliary separator roll, the snubbing pin, and the draw roll with its separator roll) is modified in that, of the two said auxiliary separator rolls, at least the auxiliary separator roll for the feed roll is replaced by a non-rotatable pin.  The auxiliary separator roll for the draw roll may also be replaced by a non-rotatable pin.  The nonrotatable pin for the feed roll may also be employed as a separator for the draw roll, and in this case the pin is cylindrical in shape and its surface is provided with spaced circumferential grooves for accommodating filaments wrapped around it.  The non-rotatable pin or pins is or are preferably parallel to the axes of the feed and draw rolls.  The pin(s) may be of "Faradex" (a refractory consisting mainly of titanium dioxide) or of "Sintox" (a sintered aluminium oxide).  Wraps are taken round the pin(s) so that each wrap has an arc of contact of about 180 degrees.  Preferably one non-rotatable pin of "Sintox" is used as a separator for both feed and draw rolls, the pin being provided with V- or U-shaped grooves.  In an example, a single separator pin of "Sintox" of 0.25 inch diameter and 2 inches length is provided and has three spaced circumferential grooves with U-shaped bottoms for accommodating wraps from the feed roll, the spacing between them being 0.125 inch, and one similar groove for accommodating one wrap from the draw roll and positioned 0.5 inch away from the nearest of the feed roll grooves.  The modification of the parent invention reduces variations in the draw ratio due to slippage of the filaments on the feed roll.
