Title: Improvements in or relating to a chip washer
Inventor: HARSHBERGER CHARLES WILLIAM
IPC: B03B5/62
Filed: 1964-07-30
Abstract: 1,022,789. Washing wood chips. HARSHBERGER EQUIPMENT CO. July 30, 1964, No. 30254/64. Heading B2H. Apparatus for washing wood chips to remove foreign matter injurious to defibrating machines is provided with nozzles 18, 19, Fig. 3 (not shown), which direct jets of water supplied by a pipe 71 against chips delivered by a feeder 11 into a wash trough 10 in which movable baffle boards 25 serve both to remove the sunken foreign matter from the bottom of the trough and form a series of submerged weirs, the chips being arranged to float from the trough, on the water supplied by the nozzles, on to an inclined vibrating screen 46 via a duct 40. Turbulent flow over the baffle boards 25 in the trough 40 is produced by maintaining the level of the water in the trough above the upper edges of the baffle boards; this may be effected by arranging the bottom of the duct 40 at approximately the same level as the upper edges of the baffle boards and maintaining a shallow depth of water in the duct. The baffle boards may be conveyed either continuously or intermittently by chains 26 driven over sprockets 31, 32, 33, 34 by a motor 35, the boards discharging the foreign matter over an incline 28 into a receptacle 30 for disposal. The vibrating screen 46 is driven through an eccentric or crank shaft 47 by a motor 48 and serves to remove any remaining foreign matter and dewater the chips which are delivered on to a transverse screw conveyer 50 which in turn feeds an elevating conveyer 52, the conveyers being driven by a motor 55 and serving to overturn the chips for drying purposes. The conveyer 52 discharges on to a conveyer belt or receptacle ready for treatment in a defibrating machine. Matter passing through the vibrating screen is collected in a trough 67 and discharged by a conveyer 61 over an incline 63a into a receptacle 65 for disposal. Water overflows the trough 67 into a pit 60 whence it is recycled back to the nozzles.

Patent GB-823981-A (GB)
Title: Improvements in or relating to colour television apparatus including frequency changing apparatus
IPC: H04N9/45
Filed: 1956-10-05
Abstract: 823,981. Colour television. FERNSEH G.m.b.H. Oct. 5, 1956, No. 30404/56. Class 40 (3). [Also in Group XL (c)] In a colour television system, the frequency separation of sound and vision carriers and twice the line frequency (h) are both derived from the colour sub-carrier by means comprising only frequency dividers with integral ratios and frequency converters having conversion factors between 0.5 and 1.5. The colour sub-carrier frequency (7x7x11 h/2) is generated by a crystal oscillator 1 and is passed by a buffer stage 2 to a socket A from which it may be fed to a colour modulator. The voltage at the cathode of valve 2 is fed via a second buffer stage 5 to a locked oscillator frequency divider 7, the division ratio of which (7 : 1) is governed by the time constant of the transformer 8 and the resistor 9. The divided frequency is added to the sub-carrier frequency in the ring modulator 11 and the sum (8 Î 7 Î 11 h/2) is selected by the tuned circuit B. A similar frequency changer 12, 13, 18 provides 8 X 8 X 11 h/2 which is fed via buffer stages 19, 20 to control the separation between sound and vision carriers. As described, this frequency is 5.5 Mc/s. A frequency of 8 X 11 h/2 obtained from the second frequency divider 13 and is reduced to twice the line frequency (i.e. 31.25 kc/s.) by a similar divider having a ratio of 11 : 1, followed by a bistable multivibrator 16. Another embodiment (Fig. 2, not shown) is described wherein the crystal oscillator 1 operates at 3 X 17 x 11 h/2 and the same output frequencies are obtained by using the difference from one of the frequency changers.

Patent GB-1044175-A (GB)
Title: A method and apparatus for the processing of filaments
IPC: D01D10/04
Filed: 1964-08-04
Abstract: Apparatus for continuously and simultaneously wet processing a plurality of yarns, preferably regenerated cellulose yarns, comprises a processing roll, a first group of other rolls having their axes substantially lying in a common plane and at differing intervals from said processing roll, and at least one other group of other rolls having their axes substantially lying in another common plane, so that a number of yarns equal to the number of all other rolls may be helically moved along individual paths circumscribing said processing roll and one or more of said other rolls, each path being external to the path or paths which circumscribe one or more rolls nearer to said processing roll. In apparatus shown, 10 is the processing roll, the different sections of which may be kept apart from each other by means of a vacuum applied to perforated bands (not shown), as in Specification 1,044,174, or by flanges or other suitable means, 12 is a guide comb for the yarns, intended to minimize the small differences in the pitch of the helical turns of different yarns which are being processed.  The comb teeth are preferably arranged in relation to the yarn paths so that one turn of each yarn only can be passed in the space between two adjacent teeth, and in general, one turn of each one of the yarns being processed is passed therebetween. A tiltingly fitted guide comb, as described in Specification 1,007,154, may be used, 13-16 are forwarding rolls and 17-20 are separating rolls.  In Fig. 2 not shown the eight yarns being processed travel along parallel and equal paths on the lower surface of processing roll 10, and then issue form the section 21 thereof, whereupon the yarns e.g. 11C and 11D are diverted from their straight paths by the forwarding roll 14.  While the yarn 11C is brought into contact with the separating roll 17, the yarn 11D is separated therefrom, and continues its path of travel towards the separating roll 17, the yarn 11D is separated therefrom, and continues its path of travel towards the separating roll 18, whereupon it is intercalated with the yarn 11E, coming in from the forwarding roll 15, which serves also as support for the yarn 11F, which is diverted in the direction of separating roll 19, and so on.  Thus forwarding roll 13 serves only for yarn 11B, the path of which is defined by the rolls 13 and 17.  Yarn 11A may also be added to the other seven yarns, coming into contact only with the forwarding roll 13, apart from roll 10.  In Fig. 3, not shown five yarns each extruded from an associated spinneret are simultaneously processed.  Six auxiliary rolls are fitted, of which roll 13 serves as a guide for two yarns and roll 14 as a guide for three yarns.  Each yarn is associated with two rolls.  Yarn 11B is associated with rolls 13 and 18, and yarns 11E and 11F are respectively associated with roll pairs 14-19 and 14-20.  A further yarn 11A may be added, which will only contact roll 13 and roll 10.

Title: Improvements in unloader valves for hydraulic pumps
IPC: F04B49/10
Filed: 1946-10-14
Abstract: 626,499. Fluid-actuated valves. TECALEMIT, Ltd., and LE CLAIR, C. C. S. Oct. 14, 1946, No. 30592. [Class 135] An unloader valve apparatus for a hydraulic pump having an inlet connected to the pump outlet, a main outlet connected to a delivery pipe and an auxiliary outlet connected, e.g., to the pump reservoir, is provided with alternately opening and interconnected main and auxiliary valves actuated by a flow and pressuresensitive device, and adapted so that when pressure in the delivery pipe is low the main valve is opened to allow liquid to pass from the pump through the said device to the main outlet, and when pressure in the delivery pipe approaches pump delivery pressure the auxiliary valve is opened to pass the liquid from the pump to the auxiliary outlet. A piston 17, adjustably loaded by a spring 27, is formed with ports 20 surrounded by an annular seating 19 cooperating with the main valve 35 which is rigidly attached to a spindle 22 carrying the auxiliary valve 25. A ported skirt 38 on the main valve abuts against a partition 9 and limits the opening of the auxiliary valve, thus sufficiently restricting the liquid flow from the inlet 2 to the auxiliary outlet 5, to ensure the maintenance of a low back-pressure below the piston 19. Failure of the pressure in the main outlet 4 enables this back-pressure to lift the piston 19 to close the auxiliary valve, and the full pump delivery pressure then acts to lift the piston clear of the main valve and to allow liquid flow through the port 20 to the main outlet, until the pressure therein returns the piston and valves to their original position. A throttle port 21 provides a restricted communication across the piston when the main valve is closed. A safety valve 44 prevents excessive pressure building up in the valve body. In a modification the throttle port is located in the wall of the valve body and is provided with a detachable jet member which may be replaced by a similar member having a different effective area.
