Title: An Automatic Water Flow Apparatus.
Inventor: SHIMIZU YOSHIO
IPC: G05D9/12
Filed: 1967-03-17
Abstract: 1,182,837. Automatic water level control. Y. SHIMIZU. March 17, 1967, No.12591/67. Heading G3R. The water level at a point in a channel downstream from a gate is automatically maintained within predetermined upper and lower limits by a control system comprising a float sensing the water level at the point, first and second normallyopen switches which are closed when the level is respectively above and below the upper and lower limits to energize an electric motor in a gateclosing and a gate-opening direction respectively until the level is restored and a timer operative on and during closure of either of the switches to cyclically close and open the respective motor circuit being controlled. Thus the energization of the motor is delayed for a predetermined time and the motor, when energized, only runs for a predetermined time, the effect being to move the gate in steps unless the level is restored during the first motor operation. If, during a control action to supply more water, the gate is operated to its fully-open position, an auxiliary gate-closing motor circuit is immediately closed and the gate is moved to its fully-closed position without intervention of the timer, whereupon the gate will rise again still without intervention of the timer. This cycle of events is repeated until the level is restored to its required position, whereupon the timer again becomes effective, or until a remotely-controlled main switch is operated to close another gate-closing motor circuit whereby the gate is closed and remains so until an opening signal is sent from the remote control station. Cyclical closing and opening of the gate also occurs when the water level at the gate drops below a predetermined value, this operation again being made without intervention of the timer and until the levels at the gate and control point are restored or until the remotely-controlled switch operates in the manner previously described. During normal operation of the control system a conventional flowmeter operates to measure the quantity of water passing through the channel, the meter being supplied with pulses of a presettable number per unit of time proportional to the calculated flow quantity per same time unit in the channel. The motor control and measuring circuits are described in detail, Fig. 3 (not shown), including an arrangement to close the gate fully and de-energize the control system when a predetermined quantity of water has passed through the channel.

Abstract: 644,317. Gas turbine plant. ROLLSROYCE, Ltd. May 12, 1947, No. 12823. [Class 110(iii)] [Also in Group XXIX] In a fuel system for a gas-turbine engine in which constant-volume, engine-driven, pump 6 passes liquid through restricting means 7, variable by a speed-selecting device 9, and in which means responsive to the pressure drop across the restriction is operative to vary the delivery of a fuel pump 1 supplying the engine, a connection downstream of the restriction 7 is taken to a piston-and-cylinder servomotor 16 acting on the fuel pump 1 and then past a valve 14 controlling the pressure in the cylinder, and the valve is oppositely loaded by the means responsive to the pressure drop across the restriction and by resilient means varied in accordance with the position of the piston-and-cylinder 16. As shown, the pump 1 is a multi-plunger pump feeding fuel to injection devices 3, and the stroke of the pump is varied by a swashplate 2 acted upon by the spring- loaded servo-piston 16. The pressure upstream of the restriction 7 is applied to the inside of a capsule 11, and the pressure down-stream is applied to the outside of the capsule and also to the left-hand face of servo-piston 16. This latter liquid pressure and, hence, the position of the piston and of the swashplate, is controlled by means of valve 14 which is carried by a leaf spring 17 and is controlled by capsule 11. The resultant movement of piston 16 is applied through a lever 23 and spring 20 on to leaf spring 17. The spring 20 may be omitted. To prevent over- or under-fuelling, a device 24 similar to that set out in Specification 639,261 is incorporated in the system. Restriction means similar to those set out in Specifications 639,260 and 639,262 may be substituted for that shown.

Abstract: 1,217,993. Finishing fabrics. SAMCOE HOLDING CORP. 11 March, 1969, No. 12836/69. Heading D1S. In a process of converting a tubular knitted fabric into an edge-gummed open-width fabric by spreading, steaming, gumming, slitting, opening and gathering the fabric, the fabric, in flat tubular form, is engaged internally by opposed side edges substantially continuously from the beginning of the spreading stage to the slitting stage; the fabric is drivingly engaged by its internal edges from regions immediately downstream of the spreading stage and extending to the slitting stage and is thereby conveyed continuously to the slitting stage; the fabric is engaged by its internal edges in the spreading stage and is maintained while in this stage free of driving pressures on its external edges; and the edges of the fabric are conveyed at a different speed in the spreading stage than in the subsequent stages. The knitted tubular fabric F, Fig. 3, passes through a set of straightening rollers 10 and passes over an elongate frame 11 comprising spreading and processing sections 12, 13 each including a pair of belts 14, 15, respectively, Fig. 4, to engage the internal edges of the fabric. The frame 11 is supported at its forward end by a structure 16, Fig. 3, which includes means for driving the belts 15 at a point downstream of a slitter knife. The belts 14 are driven only by the fabric passing thereover. The frame 11 is guided by width-adjustable edge rolls 17, Fig. 4, which do not have any driving or pressure engagement with the fabric but are grooved to engage pulleys 18, 19 about which the belts 14, 15 are trained. The fabric is fed over the stage 12 by rollers 20, 21 having a high friction surface, e.g. felt, and which are driven in synchronism with the rolls 17 by a motor (not shown) via a chain and sprocket gearing at a peripheral speed higher than the speed of the belts 15 to over feed the fabric to the stage 13. The fabric 11 may be additionally supported by a roller 35, Fig. 3, supporting a roller assembly 36 within the fabric. The belts 15 carry the fabric between steam boxes 37 to relax or set the fabric. An air blower nozzle 38 is provided to prevent steam from condensing on the rolls 17, 20, 21. A similar nozzle (not shown) may be provided on the downstream side of the boxes 37. The fabric passes under a wheel 39 which applies a narrow strip of gum to the longitudinal centre line of the upper surface of the fabric. If the gum is an aqueous solution or suspension, the fabric is passed through a heating chamber 41 to drive off moisture or, if the gum is a hotmelt or thermoplastic composition, the chamber 41 need not be operated or may be omitted. The gummed fabric is severed by a knife 42 along the centre line of the gummed strip. The fabric passes between rollers 43, is spread and opened by a device 44 as described in Specification No. 940,612, passes onto a conveyor 47 and passes to a wind-up 49 or a folder.
