Title: Apparatus and method for continuous processing of rayon filaments
IPC: D01D10/04
Filed: 1957-01-25
Abstract: <PICT:0811272/IV (c)/1> Apparatus is described for the fluid treatment of yarn by a method comprising the successive steps of continuously winding the yarn in a multi-layer cross-wound manner to form a cake, advancing the cake from the area of winding, passing successive liquids from the inside of the cake to the outside as the cake is advanced and unwinding the cake from the inside at substantially the same rate as the yarn is wound.  As shown, yarn to be processed is led through a reciprocating guide 12 and is wound cross-wise to form a cake 3 on a conveyer comprising interdigitating bars 4 carried by flexible lower connections 37, 38 and top spiders 20 and driven by shafts 9, 10, from the gears 15.  The top connections allow for the in-and-out and the up-and-down movement of the bars 4 under the control of cam-operated rockers 16, 17. Treating fluid is supplied at 14 to a stationary member 7 integral with the base 13 and escapes by way of ports 35 towards a perforated tube 5, ribbed internally at 6 to prevent axial flow of liquid and rotated by shaft 8 so that by centrifugal force fluid is thrown outwardly through the advancing yarn mass.  The fluid escaping through the yarn mass is collected in gutters 2 in the casing and flows outward through spouts 18 and troughs 9 to collecting means.  A wire cage 22 supports the yarn mass from the outside whilst hot air from the ducts 24 flows through the yarn mass to an exhaust casing 21, drying the yarn whilst the yarn is unwound from the inside of the cakes.

Title: Pumping system
IPC: A61M5/36
Filed: 1972-01-20
Abstract: 1367391 Reciprocating pumps SHERWOOD MEDICAL INDUSTRIES Inc 20 Jan 1972 [4 Feb 1971] 2847/72 Heading F1A [Also in Divisions A5 and H2] A reciprocating pump for use in an infusion system Fig. 1 (not shown) includes a control circuit Figs.3 and 4 (not shown) and see Division H2 by which the pump is shut off when its actual pumping rate differs from its selected pumping rate by more than a predetermined amount. The pump comprises a piston 44 sliding in a disposable syringe 42 coupled to a two-way valve 40 having an inlet 36 and an outlet 46. The piston 44 is reciprocated through gearing 121-140 by a bi-directional D.C. motor 120, which is reversed whenever a projection or a magnet 150 on a carrier 140 connected to the piston actuates forward and reverse limit switches 154, 152. The motor may be driven by re-chargable nicklecadmium batteries 160 or from a transformed external A.C. source. The pump, valve, motor and batteries are removably held in a two-part moulded casing 90, 170 the former part also containing a printed circuit control board 156 for the pump. The control circuit allows any one of various predetermined pumping rates to be selected, the use of differing size syringes allowing the choice of differing ranges of pumping rates. The motor 120 is driven by pulses having a less than 100% duty cycle, the duty cycle being increased by the control circuit at the higher selected pumping rates, though the reverse piston stroke always occurs at maximum speed. During the off-time of the pulses, the motor 120 acts as a tachometer generating a back EMF, the size of which provides a measure of the pump load and which is used to adjust the on time of the pulses to compensate for load variations due e.g. to the use of different syringes or the pumping of different fluids. A battery variation compensation circuit is included in the control circuit, which decreases the off-time of the drive pulses during the forward pump stroke to compensate for the battery supply voltage falling with time. The rate control shut off circuit of the control circuit operates by comparing a derived analog wave form representative of the selected pumping rate with the actual pumping rate as determined from the frequency of actuation of the limit switches 154, 152. The control circuit also includes circuits which shut down the pump if the pump speed control system should fail in a way to cause the pump to operate at full speed, or if bubbles in the pumped fluid are determined by electrodes 212 (e.g. if the fluid source has been emptied),  or at excessive pump discharge pressures, as well as an indicator circuit for these latter two conditions and a circuit allowing the pump to be primed. Reference has been directed by the Comptroller to Specification 1232655.

Title: Improvements in and relating to hydraulic control valves
Inventor: TOWLER FRANK HATHORN
IPC: F16K17/04
Filed: 1951-02-06
Abstract: 730,852. Hydraulic presses; valves. ELECTRAULIC PRESSES, Ltd. Jan. 18, 1952 [Feb. 6, 1951], No. 2885/51. Classes 69 (2) an2 135. In a hydraulic control valve having a valve plunger operable by a pilot valve or a solenoid to control the supply of pressure liquid to a hydraulic press, one end of the valve plunger is enclosed by a space to which pressure liquid is supplied and an automatically - operating valve is fitted subjected to press exhaust pressure which prevents the escape of liquid from the said space and the movement of the valve plunger to its full exhaust position until the exhaust pressure has fallen to a safe value. As shown, a valve plunger 1, Fig. 1, slidable in a casing 2 to control a supply port 6, a press port 5 and an exhaust port 4 has its upper end enclosed in a chamber 7 connected through a passage 13 and a spring-loaded valve 11 subjected on its lower face to press exhaust pressure to a pilot valve (not shown). On movement of the pilot valve to admit pressure liquid to the chamber 7, the valve plunger 1 moves downwardly against its spring 8 to connect the main supply of pressure liquid to the press cylinder. To exhaust the press cyllinder, the pilot valve is moved to its release position whence the exhaust pressure acting on the valve 11 urges it upwardly to throttle the outlet from the chamber 7 and trap liquid therein, the plunger 1 having moved sufficiently to permit a restricted opening of the exhaust port 4. As the exhaust pressure falls, the valve 11 moves downwardly to permit the escape of liquid from the chamber 7 and eventually the full opening of the port 4 to exhaust. In a modification, a solenoid takes the place of the pilot valve and is affixed to the lower end of the plunger 1. When the solenoid is energized the plunger moves downwardly to connect the supply and press ports. As before, liquid trapped in the chamber 7, which in this case is not under pressure, prevents the initial full opening of the plunger to exhaust, the chamber 7 functioning as a dashpot. In another modification, for controlling a double-acting press, the plunger is formed with an extra land and controls a further press port and further exhaust port. A further chamber 7 encloses the other end of the plunger and a double-acting pilot valve directs pressure liquid to the chambers 7 alternately.

A switch, e.g. an air-insulated or oil-immersed high or low tension switch, has its contacts mounted at the rear of an auxiliary panel 2 and operable through gearing by a handle 12 mounted on a spindle 9 and arranged in front of a main panel 1 supporting the auxiliary panel by means of bolts 33. In a multi-pole change-over switch, the movable flicker-type contact arms 3 are pivoted co-axially in brackets 4 and are connected together by a bar 17 fixed at 18 to an operating arm 15 secured to a bevel wheel 14. The latter meshes with a pinion 13 on the spindle 9 so that rotation of the handle 12 causes rotation of contacts 3 from one set of fixed contacts 5 to a second set 6 mounted on a rearward extension 7 of the panel 2. In a modification, Figs. 4-6 (not shown), suitable for heavier currents, the bevel gear and pinion are replaced by a worm and worm wheel. The panels 2, 7 may be in one piece or, as shown, may comprise separate parts secured together at 34. The contacts 6 may alternatively be arranged so that less or more than 90 degrees rotation of the contacts 3 is required, and the switch may alternatively be of the simple make-and-break type. A lost-motion spring connection may be arranged between the arm 15 and the contacts 3 so as to provide a rapid action.

A rupture unit for a safety device comprises a control element 19, a segmented supporting element 20 mounted in backing contact with a rupturable sealing element 22 and an annular retaining ring 21. The control element 19 of light gauge sheet material is retained in contact with the segments 29 of the supporting element by means of clips 34 attached to the supporting element and having fingers 37 extending over the marginal edge of the control element. The supporting element 20, the sealing element 22 and the retaining ring 21 are secured together by spot welds at their marginal edges and the rupture unit thus constituted is clamped between clamping rings mounted over the relief opening of the vessel or appliance to be protected. The clips 34 are designed to give way at the predetermined calculated safety pressure thereby rendering the supporting member 20 ineffective so that the sealing member ruptures. An additional disc 40 may be inserted between the supporting element 20 and the pressure sealing element 22 to protect the pressure sealing element from the points of the segments 29. In another embodiment the rupture unit is rendered capable of functioning under vacuum pressures by reversing the order of assembly of the elements. In a further embodiment the sealing element is contained between a supporting element and control element on each side so that it relieves both pressure and vacuum.
