Title: Flow control apparatus
IPC: C02F1/68
Filed: 1966-08-16
Abstract: 1,128,741. Valves. AQUAMATIC Inc. 16 Aug., 1966 [23 Aug., 1965], No. 36715/66. Heading F2V. [Also in Division B1] A valve M controlling a regenerating cycle of a water treatment system is actuated by a set programme. A synchronous motor is connected through a reduction gearing to drive a toothed wheel 72, having a time indicating scale, to cause the wheel to rotate once every 24 hours. A second wheel (not shown) is moved one step every day and carries presettable pins which may be positioned to a " set " or " off " position. A lever 90 pivoted at 85 is rocked by a cam 64a, driven by the motor to rotate a toothed wheel 100, but this wheel has one missing tooth such that the rocking of the lever 90 by the cam 64a, will not rotate the wheel until the lever is actuated to overcome the tooth gap, after which the cam causes a stepped rotation of the wheel through one revolution until the lever again engages the gap. The initial actuation of the lever to overcome the gap is produced by the pins of the second wheel (not shown) when in the " set " position. These pins act on an arm of lever 84 to actuate the lever 90 the required amount to overcome the tooth gap at the time set by the programme. During rotation of the wheel 100, an internal cam track 105 reciprocates a lever 107 through cam follower 106 to actuate the valve M. The valve M comprises a housing having chambers 21-25 interconnected by ports 41-44. A valve rod 40 has a part controlling the flow through port 41, a valve 46 loaded by a spring towards an abutment 52 to control the flow through ports 42, 43 and carries a spring loaded non-return valve 49 which controls flow through port 44. The rod may also have an extension 142 acting as a valve closure for a port 143. In operation, the chamber 21 is connected to drain, the chamber 22 to the top of the treatment tank, the chamber 23 to the raw water supply, the chamber 24 to the service line and the chamber 25 to the bottom of the treatment tank. With the valve in the position shown, the raw water passes from chamber 23 through chamber 22 into the treatment tank and from the bottom of the tank to chamber 25. When a tap in the service line is open, the non-return valve 49 is opened to allow flow from chamber 25 to chamber 24. When the programme acts to rotate the wheel 100, the valve is moved to the right to connect chamber 21 to 22 and chamber 24 to 23 while closing the connection between chambers 23 and 22, also, the extension 142 opens port 141. Raw water now passes from chamber 23 to 24 and flows through an ejector E to chamber 25 and entrains regenerant from inlet 144 and pipe 17. Raw water is thus available at the service line and the regenerant flows from chamber 25 up through the treatment tank to chamber 22 and thence to drain through chamber 21. After a complete revolution of wheel 100, the valve assumes the position shown. The cam 105 is shaped to provide the necessary dwell.

Title: Producing biaxially oriented polypropylene film
IPC: B29C48/08
Filed: 1962-09-27
Abstract: 964,627. Biaxially oriented polypropylene film. NATIONAL DISTILLERS & CHEMICAL CORPORATION. Sept. 27, 1962 [Nov. 28, 1961], No. 36785/62. Heading B5B. Polypropylene film suitable for biaxial orientation is produced by melt extruding polypropylene containing more than 70% by weight of isotactic polypropylene at an elevated temperature of, for example, about 350 to 550 F. and at a draw down ratio of at least 7:1 to form a flat film web, having a high degree of melt orientation, rapidly cooling the extruded web contacting it with cooling means, for example, by passing it through a bath of cooling liquid (preferably water) or on to the surface of a chill roll, the surface of the bath liquid or the upper surface of the chill roll being <SP>1</SP>/ 16  to 2 inches from the lips of the extrusion die. After being withdrawn from the quench bath and dried or withdrawn from the chill roll, the film may be longitudinally stretched, e.g. at about 200 to 300 F. to a stretch ratio of about 1.2: to 1.6:1, and may thereafter be heated while under longitudinal tension to about 250 to 300 F. The web may then be stretched transversely, e.g. at about 200 to 300 F., while it is under longitudinal tension, to obtain a stretch ratio of about 6 : 1 to 12 : 1. The thus biaxially oriented polypropylene film is finally cooled to about ambient temperature and collected. The film may be heated to a temperature of, e.g. 300 to 350 F., for a sufficient period of time, e.g. 3 to 10 seconds, to effect annealing, while it is maintained under longitudinal and transverse tension. The cooled biaxially oriented film may be further stretched longitudinally at about 200 to 300 F. and a stretch ratio of about 1.3: 1 to 3: 1 to obtain balanced biaxially oriented polypropylene film. The cooled biaxially oriented film may be trimmed to remove film edges which have not been transversely stretched and the trimmed edges may be recycled to the extruder. The web of film may issue from the extrusion die at a thickness of about 2 to 20 mils. which may be 8 to 12 times the final thickness of the film. When the film is quenched by passing it through a bath of liquid, e.g. water, at about 40 F., the surface of the liquid must be free from ripples and its surface may be maintained at a distance of # to 1 inch below the die lips.

Title: Improvements in or relating to sewing machines suitable for use in sewing together an upper and sole member of a shoe
IPC: D05B15/00
Filed: 1962-09-28
Abstract: 1,023,646. Sewing machines. BRITISH UNITED SHOE MACHINERY CO Ltd. (UNITED SHOE MACHINERY CORPORATION). Sept. 26, 1963 [Sept. 28,1962], No. 36817/62. Addition to 811,605. Heading D1G. [Also in Division A1]. The machine described in the parent Specification is modified to provide for automatic stopping upon operation of the welt-severing knife, whereby the machine is arranged to stop after the insertion of two stitches in the initially-sewn end of a butted welt, or to leave a free 1/4 inch of an unbutted welt. The machine also stops automatically upon breakage of the needle thread. The machine is started by depression of a treadle 20, whereby a toggle 40, biased to the straightened position by a spring 42, is broken, and a rod 48 is raised to withdraw a locking bolt 34 from an oscillating clutch lever 36 and to close a main switch S3. The machine then operates to attach a welt 12 to a disc. If the ends of the welt are to abut, a knee lever 22 is actuated near the completion of the operation to close a switch S2 and, via a cable 32, to position a feeler 26 adjacent the work. When feeler 26 engages the initially stitched end of the welt, a pin 30 closes a switch 51, in series with switch S2, to energize a solenoid 21 for operating the welt severing knife 24. A cam 52 on the latter thereby momentarily closes a switch S4 to energize a relay R1 for closing holding contacts C1 and contacts C2 for energizing an adjustable timing relay TR2. After the desired lapse of time contacts C3 close for energizing a solenoid L2 adapted, via a linkage 50, to lower bar 48 for withdrawing bolt 34 to stop the machine. For sewing a welt around the forepart of a shoe, switch S1 is permanently closed, and knife 24 is actuated upon closure of switch S2 by the knee lever 22. Instead of an adjustable timing relay two separate relays may be provided, with a switch for pre-selecting the relay having the appropriate delay time. For stopping the machine on breaking of the needle thread, the thread take-up described in the parent Specification is modified. Thread 72 passes over an idler pulley 74 and a pulley 66 carried by the oscillating thread take-up arm 64. An arm 76, pivoted at 77, carries a pulley 78 biased against the thread between the pulleys 66, 74 by a spring 80 acting on an arm 82 rigid with arm 76. A pivoted arm 90 is spring-biased to engage a roller thereon with the upper edge of arm 64. During the downward, thread-releasing stroke of arm 64, a roller 86 on an arm 84 rigid with arm.90 cooperates with a cam surface on arm 82 to hold the latter raised. During the upward, thread take-up stroke of arm 64, roller 86 enters a recess 88 in arm 82, and the latter is thereby held in the raised position by the pressure of the tensioned thread on roller 78. If the thread breaks, arm 82 thereby drops during the upward stroke of arm 62 to close a switch S5 to energize the machine-stopping solenoid L2.
