Filed: 1965-02-03
Abstract: 1,068,502. Milk treatment plant A.P.V. CO. Ltd. Jan. 11, 1966 [Feb. 3, 1965; Sept. 7, 1965], Nos. 4624/65 and 38245/65. Headings A2B and A2D. [Also in Division F2] A flow changeover device comprises four fluid connections 22 arranged to be connected to external flow conduits, a pair of movable conduit sections 25 adapted to connect the fluid flow connections together in pairs, and means for moving the conduit sections so as. to provide alternative interconnections between the connections 22. The latter are arranged at the corners of a square while the conduit sections 25 are secured to a plate 23 rotatably and slidably mounted on a spindle 28. A toggle unit 29 actuated by a double-acting ram 37 lifts the plate 23 prior to rotation by a vane type actuator 39 and causes sealing pressure to be applied to rubber joints 26 after each actuation. An abutment 48 co-operates with adjustable stops (not shown) to limit the rotation of plate 23 while limit switches 43 operate a remote indicator and ensure the connections are correctly made before fluid enters the circuit. After the connections have been changed a cleaning solution is passed from a spray 44 into a shroud 46 fitted with a drain connection 45. A transparent plastic cover 47 is also fitted to the device which may be used in a U.H.T. milk processing plant having a cleaning circuit as described in Specification 1,027,848. During processing, one section 25 interconnects two stages of the plant while the other forms a connection between the lines of a cleaning circuit. Rotation of the device through 90 degrees causes cleaning fluid to be passed simultaneously through the two stages. The device may also be used to enable a number of milk storage tanks (1, provisional drawing 38245/65, not shown) to be connected to milk inlet lines (7) or to a cleaning circuit and to enable the outlet lines (10) to be connected to extraction pumps (12) or to a second cleaning circuit. The groups of inlet and outlet lines may be selectively connected with either line of a single pair of inlet and outlet lines (2, 3) by banks of air-operated valves (4, 5) while vent valves (8) fitted with filters (9) permit the lines (7) to be drained by gravity.

Title: Improvements in and relating to boring or drilling machines
IPC: B23Q5/32
Filed: 1959-02-11
Abstract: 858,570. Drilling-machine details. KOVOSVIT NARODNI PODNIK. Feb. 11, 1959 [Feb. 12, 1958], No. 4852/59. Class 83 (3). A drilling &c. machine comprises a control lever 8 movable into three positions I, II, III, for respectively engaging power-feed of the sleeve 2 of the tool-spindle 3, fine manual-feed, and rapid manual-feed. A pair of levers 8 is pivoted on a drum 7, which is keyed to a shaft 5 having a feed-pinion 4 meshing with a rack on the sleeve 2. A worm-wheel 22 is connected to shaft 5 by a clutch element 20 and is driven by a worm 23 on a shaft 24 having a wheel 27 for fine hand-feed. Shaft 24 may also be power driven, through a clutch 33 operated hydraulically or (as shown), electrically. A further clutch 30 on shaft 24 slips on overload, an element 28 of the clutch rocking a lever 45, 46, which causes a further lever 40 to open a switch 36 for disengaging clutch 33. The lever 45, 46 engages the inclined end 47 of a link 48 on lever 40, forcing a slot s in the link into engagement with a guideway 51, against the influence of springs 52, 43 in which it is held by spring 43 until released as described below. A projection 42 on lever 40 bears against a sleeve 10 movable along shaft 5 by the levers 8. The sleeve has a formation F in its bore, for operating levers 13 pivoted at 14 in a housing 15 slidable on shaft 5. Links 16, 17 engage bearings in the ends of levers 13 in a ring 18 on shaft 5, and in clutch element 20. As shown, the drive is arranged for power-feed, i.e. levers 8 are in position III. To restore power-feed after this has been disengaged by clutch 30, levers 8 are moved to displace sleeve 10 and cause projection 42 to move out of a groove in the sleeve. This moves linkage 40, 48 and allows spring 52 to withdraw slot s from the guideway 51, and the spring 43 to restore the linkage when levers 8 are returned to position III. In position II, the drive is arranged for fine manual-feed by wheel 27, clutch 33 being disengaged by switch 36, which is opened by lever 40 as projection 42 is cammed out of the groove in sleeve 10. In position I, formation F in the bore of the sleeve upsets the levers and links 13, 16, 17 and opens clutch 20, thus allowing fast manual feed by direct rotation of shaft 5 by levers 8.

Filed: 1947-02-19
Abstract: 621,645. Pulp mills. MORDEN, C. W. Feb. 19, 1947, No. 4912. [Class 59] A pulp-treating and refining machine comprises a conically-shaped rotor having an exterior attritioning surface, a non- rotating shell having an interior attritioning surface surrounding the rotor, and a semi-floating mounting for the shell adapted to permit some self-alignment of the attritioning surface of the shell with respect to the attritioning surface of the rotor in their operating relationship. A hollow conical rotor R with exterior attritioning bars 27 is surrounded by a stator shell S having interior attritioning bars 32 which co-operate with, and may be slightly oblique to, the bars 27. The shell S has a pair of diametrically opposite side arms 41, 42, Figs. 2, 3, which are attached to shoe elements 45, 46, respectively, and resiliently mounted shafts 43, 44. These shoes 45, 46 are loosely fitted in side chambers 47, 48, of the outer casing 10, which are slightly larger in section than the shoes so as to allow the shell S a certain amount of lateral play. The shell S is adjustable longitudinally by worm gears on the shafts 43, 44. Two methods of treatment which may be used with the machine are described, the first, which is more of a " hydrating " treatment, is described with reference to Fig. 1. The material to be treated is fed from an inlet 57 to a chamber 54 whence it passes through the small diameter end of the rotor, through the interior thereof and then back between the attritioning surfaces to a chamber 34, and then out through a chamber 55 into a valve controlled outlet pipe 72 (not shown). The second method, which is stated to be a " refining " treatment and to be particularly suitable for coarse material or long rough fibres, is described with reference to Fig. 11. In this case, material from the inlet 57 passes through the chamber 54, the small end inlet to the interior of the rotor being closed, through a now opened valve port into the chamber 55, the outlet pipe 72 therefrom being closed, then through the chamber 34, between the attrition surfaces and out through a chamber 35B and a valve controlled outlet 36. In the first method the closed outlet pipe 36 re-collects "tramp" metal and other foreign bodies.

Title: Improvements in or relating to silencers and/or flash eliminators for firearms
IPC: F41A21/30
Filed: 1954-02-22
Abstract: 757,640. Silencers and flash eliminators for firearms. PATCHETT, G. W. Oct. 19 1954 [Feb. 22, 1954], No. 5206/54. Class 92 in a nrearm, e.g. a light automatic weapon, the noise and flash of discharge are eliminated by the provision of spaced sets of holes 12, 13, 14, Fig. 1, along the barrel 11 which open into annular passages formed by two spaced tubes 15, 16 surrounding the barrel so that the flow of explosion gases is repeatedly reversed before passing to atmosphere and a movable obturator at the muzzle end of the barrel comprisises two pivoted shutters 45 adapted by means initiated by movement of the breech block successively to unseal the muzzle for the passage of a projectile and to seal it immedately after passage thereof so as to prevent the gases emerging from the muzzle. On passing through the holes 12, 13, 14 the gases are deflected rearwardly by lugs 24, 25, 26 through the inner annular passage 17 and are then deflected by a plate 29 through apertures 28 into and forwardly through the outer annular passage 18 containing a helically wound length of strip metal 30 or a series of split and spread washers. The outer tube 16 which has a heat insulating lining 20 of asbestos, has an extension 37 projecting beyond the muzzle and surrouding the shutters 45 and formed with channels 43, Figs. 1, 7, terminating in aperture 44 disposed opposite holes 35 in a ring closing the forward ends of the annular passages 17, 18. The gases, after passing through the helical path in the annular passage 18 emerge through aperture 35, 44 to atmosphere. The shutters 45 are of channel section and the flanges at one end straddle a square block 46 secured over the muzzle and are pivoted thereto by screws 47. Rubber closure strips 65 are scured to the forward ends of the shutters which are urged towards each other by a spring 63 and are connected by tooth gearing. Movement of the shutters to open position is effected by a lever 53 pivoted at 54 on the extension 37 and engaging at one end with the lower shutter 45, the other end being engaged by one end of a rod 55 in a guideway 56; the other end of the rod 55 is engaged by a pivoted cranked lever 58 firmed with a projection or roller 60 projecting through a slot 61 in the breech casing 9 so as to lie in the path of movement of the breech block 62. On forward movement of the breech block 62 for firing the rod 55 is moved to the left, swinging the lever 53 and opening the shutters and on recoil of the breech block beyond the roller 60, the spring 63 closes the shutters again. Instead of the shutter 45 being moved to this closed position by the spring 63, the explosion gases may be used to operate another push rod engaged by a plunger in a small cylinder communicating with the breech end of the barrel.

Patent GB-630448-A (GB)
Title: Improvements in or relating to indicating instruments
IPC: G01R5/16
Filed: 1947-02-24
Abstract: 630,448. Indicating. LIQUIDOMETER CORPORATION. Feb. 24, 1947, No. 5294. Convention date, June 28, 1946. [Class 106 (iv)] [Also in Groups XXXVI and XXXVIII] An indicating instrument having provision for moving the indicating element to a predetermined off position when the instrument is not operating comprises means movable between an inoperative position where it is electrically and mechanically separate and distinct from the means for effecting the normal indicating movement of the indicating element, and an operative position where it will effect movement of the indicating element to the off position, means operated in response to the energization of the element moving means for holding the movable means in its inoperative position during all the time the indicating element is positioned by the element moving means, and means effective to move the movable means to its operative position on de-energization of the element moving means. A ratiometer type instrument for indicating liquid level in a tank 12 is shown. The transmitter comprises a resistance 13 divided into three sections by taps 14, 15, and engaged by a wiper 16 which is moved by a float 18. The indicating instrument 10 comprises three fixed coils 21, 22, 23, spaced about a permanent magnet rotor 24. This may include two similar permanent magnets 25, 26, Fig. 2, spaced apart on a common rotor shaft 27, the disc-like coils 21, 22, 23 being arranged between the magnets 25, 26. The shaft 27 carries a pointer 28, which moves over a scale 29. The inner ends of the coils 21, 22, 23 are connected together and their outer ends are connected through resistances 30, 31, 32 and a switch 54 to one pole of a battery 56, the other pole of which is connected to the wiper 16. The outer ends of the coils 21, 22, 23 are also connected to taps 14, 15, 35, 36 on the resistance 13. An auxiliary permanent magnet 58 is mounted on an arm 60 pivoted at 61, so that the magnet 58 can swing through an intermediate position 62, to an operative position 63. The resistors 30, 31, 32 are wound on a cast iron core 69 having a pivoted armature 71. When the instrument is energized by closing the switch 54 the armature 71 is attracted to the core and pulls the arm 60 to its inoperative position against the action of a spring 64, so that the magnet 58 is out of the field of the rotor magnet 26. On deenergization of the instrument the armature 71 is released and allows the magnet 58 to move to the position 63 under the action of the spring 64, in which position it acts on the rotor magnet 26 so that the pointer 28 is moved off-scale to the position 59. Should the pointer 28 be in the position shown, diametrically opposite to the position 59, the magnet 58 in the position 63 would exert equal and opposite torques on the rotor. This dead point position, however, is eliminated by the action on the rotor of the magnet 58 in the intermediate position 62, which starts rotation of the rotor.
