Title: Improvements in or relating to control apparatus for a reciprocable member comprising means for reciprocating the member
IPC: F41A31/00
Filed: 1949-03-29
Abstract: 689,894. Recoil apparatus for guns. JACKSON HYDRAULIC MACHINE CO., Inc. March 29, 1949 [Oct. 23, 19481, No. 8479/49. Class 92(i) [Also in Groups XXII and XXIX] In Fig. 1 an hydraulic jack comprising a cylinder 63 is operated to move its piston rod 65 in one directoin and the rod is returned by a hydraulic jack 64 having a piston rod 64b. The jack 64 is attached to the cylinder 63 by means of a device 64c. The jacks are operated by pressure from a reversible variable delivery hydraulic pump 10. The flow of liquid to and from the left-hand end of the cylinder 63 passes through a hydraulic motor 54 which drives a shaft 58 which in turn controls means which reverse the pump each time the piston rod reaches the end of its stroke. Alternatively the shaft 58 may be driven by a rack and pinion instead of by the hydraulic motor. The cylinder 63 may where the invention is used as a recoil exercizer be the cylinder for the recoil mechanism of the gun. Reversal of the pump is controlled by solenoids 11, 12 operated by means of limit switches 112, 114, Figs. 3, and 5. With the parts in the position shown liquid from the pump passes by way of a valve 40 the motor 54 and a valve 20 to the left-hand end of the cylinder, liquid from the right-hand end of the cylinder passing by way of the valve 20 back to the suction side of the pump. A make-up pump 73 supplies additional liquid to the suction side of the pump. When the pump 10 is reversed suction raises a valve member 43 of the valve 40 and closes the make-up pump line to the delivery of the pump 10 and liquid under pressure reverses its direction and passes into the jack line 66. The valve 20 has two positions only, that shown and an off position in which all ports are blocked. It is controlled by a solenoid controlled valve 30. As shown, Fig. 3, the shaft 58 through a spring 86 sleeve '84 and gear 89 drives a gear 90. The gear 90, Fig. 5, carries an operating arm 110 carrying a bearing 111. A further gear 98 is operable by a knob 106 which at the same time operates a pointer 105 carried by an internally toothed ring 104. The gear 98 carries a screw 113 which projects into the path of the bearing 111. Thus as the gear 90 is oscillated by the shaft 58 the bearing at one end of the stroke of the piston rod actuates the limit switch 112 controlling one 'of the solenoids 11, 12, and the pump is reversed and at the other end of the stroke of the piston rod the bearing contacts the screw 113 and the shaft 91 of the gear 90 is shifted against a spring 94 and the limit switch 114 controlling the other solenoid is operated to reverse the pump again. The pointer cooperates with a scale to indicate the volume of liquid required to move the piston rod through a complete stroke in one direction. The delivery of the pump may be regulated by regulating means 13, 14 controlled by knobs 15, 16. These knobs operate pointers carried by ring gears the pointers co-operating with a dial 17.

Title: Improvements in or relating to mechanism for printing late news in newspaper printing machines
IPC: B41F13/46
Filed: 1932-03-24
Abstract: 386,170. Printing late news. FOSTER & SONS, Ltd., J. and BRADSHAW, R., Soho Foundry, Preston. March 24, 1932, No. 8834. [Class 100 (ii).] In a late news printing-machine in which a number of late news printing-cylinders cooperate with an impression cylinder, each printing-cylinder is independently movable into and out of printing position and is driven by a two-part gear, one part being loose on its shaft and constantly driven from the impression cylinder and the other part being fast upon the shaft and adapted to be coupled to the fast gear by a sliding member, the actuation of which operates a gear for bringing the fast gear up to the speed of the loose gear so that the coupling can take place without shock. The box cylinders 7, 8, Fig. 2, are carried by shafts 9, 10 mounted in eccentric bearings 11, 12 rotatable by hand-levers to move the cylinders into and out of contact with the impression cylinder 6. The shaft of each box cylinder is provided with a loose gear 25, Fig. 3, driven continuously from a gear 24 on the cylinder 6, and an adjacent fast gear 87 adapted to be coupled to the gear 25 by a pin 45 carried by a slidable collar 44. The collar is actuated by manual means which also brings into operation an auxiliary gear for driving the gear 87 and causing the coupling of the gears 87, 25 to take place without shock. The auxiliary gear comprises a grooved friction wheel 29, Figs. 2 and 3, driven continuously from the cylinder 6, and a co-acting grooved wheel 32 which, with a ratchet wheel 33, is fixed to a shaft 34 mounted in eccentric bearings formed on a yoke 35 adapted to be operated by a cam 61 through a cam rod 64 to bring the gear 32 into and out of engagement with the wheel 29. A gear 36 loose upon the hub of the wheel 32 and meshing with the gear 87 is driven by the wheel 33 through pawls carried by the gear 36, so that the speed of the gear 87 is slightly less than that of the gear 25. The collar 44 is actuated by a lever 47 which is moved in one direction by a spring rod 48 under the control of a sliding member 49 having a notch 72 to engage a pawl 50 carried by the lever 47, and is moved in the other direction by the member 49 through the pawl 50. The member 49 is operated by the threaded end 74 of a shaft 54 operated by a hand-wheel 66 and this shaft also carries a gear 55 by which, through gear 56, worm 57, and worm wheel 60, the cam 61 is driven to cause engagement of the gear 32 with wheel 29. The shaft 54 is also threaded to engage a collar 67 connected by rod 68 to a collar 69 slidable upon the shaft 54 and co-operating with a rod 70 pivoted to the bearing 11 of the box cylinder shaft to prevent movement of the box cylinder into engagement with the impression cylinder until the shaft 54 has been operated sufficiently to couple the gears 25, 87 together.

Title: Improved apparatus for the treatment of sewage
IPC: C02F3/30
Filed: 1921-03-23
Abstract: 170,263. Dorr Co., (Assignees of Peck, C. L.). Oct. 14, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Plant; aerating; gravity-separation apparatus.-A sewage tank for the activated sludge process is divided by a transverse tray 20 into a lower treating-chamber and an upper settling- chamber, rotary mechanism being provided for working material settling on the tray towards openings at the periphery which allow communication between the chambers. At the bottom of the lower chamber are air diffurers 12 formed by pipes arranged as the sides and diagonals of a square. Under the influence of the air the liquid rises into a central pipe 33, the major part passing downwards again through a pipe 31, attached to the rotating shaft 23, which supports scrapers 27 directing sludge outward along the bottom of the tank to mix with the fresh liquor supplied to the tank by a pipe 28. A portion of the circulating liquid flows over the top of the pipe 33 and is directed on to the tray 20 by a concentric baffle 35. The shaft 23 supports the scrapers 27<1>, which coact with the surface of the tray. Some of the liquid passes away by the launder 36 while the rest, with sludge, is returned to the lower chamber down wells 21. Sludge is also drawn off through a pipe 45. A skimming-device 37 of involute form coacts with a stationary but partly flexible device 43 to direct fats or similar floating matter into a receptacle 44. Solid matter is prevented from settling in the bottom corners of the tank by a plough attached by a chain to the outer end of the lower scraper arm, and a chain attached to both ends of the arm is dragged over the bottom to assist the action of the scrapers. In tanks of large diameter the liquid flowing down the pipe 31 may be distributed by one or more radial pipes. Fig. 5 shows a form of the tank which can be converted for use for anaerobic treatment. In this case, the central pipe 54 is built up of sections which can be removed separately. For anaerobic treatment the pipe 54 is removed and the upper end of the wells 50 are stopped up, the upper and lower chambers communicating through wells 51 which do not reach down so far. The liquid for treatment is supplied to the upper chamber by a pipe 57, the normal supply-pipe 56 being closed.

Title: Improvements in rotary converters
IPC: H02K47/08
Filed: 1925-04-07
Abstract: 232,588. Meller, R. April 15, 1924, [Convention date]. Rotary converters; commutating windings; exciting.-For obtaining different secondary characteristics in a rotating-field converter (i.e., a converter in which the secondary field is induced solely by the alternating currents in the primary member), the iron yoke surrounding the armature is provided with one or more field windings which magnetize the armature approximately in the same axis as the secondary continuous current. The armature e, Fig. 1, is fed with three-phase current at r, s, t and supplies continuous current at the commutator brushes a. b. The yoke f is recessed in the neighbourhood of the brushes in order to improve commutation. At synchronous speed, the rotating alternating field due to the three-phase armature current will be stationary in space, and the resultant of this field, the continuous-current armature field, and the field produced by the winding F will be in some such direction as the line x, y and inclined at an angle a to the brush axis a, b. Hence, by regulating the strength of the field F, the angle a and therefore the continuous-current voltage may be varied. A steeply falling secondary voltage characteristic suitable for arc-welding may be obtained by connecting the field winding F in series with the brushes a, b, as shown in Fig. 2. If a slightly falling or a rising characteristic is required an additional separately-excited field winding may be employed. Instead of the separately-excited winding, a shunt winding may be supplied through a rheostat from an auxiliary set of brushes displaced by 90‹ with respect to the main brushes. Where it is necessary to use commutating poles, a compounding field winding is provided to compensate for the torque exerted by the commutating poles, and the field windings are wound in grooves in the poles so as to give approximately sinusoidal fields in the air gaps. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter :-If the converter is shortcircuited. a leading primary current will be taken so that the machine can operate as a synchronous condenser. For a small range of secondary voltage regulation, a shunt field winding connected across the main brushes may be used. Commutation may be improved by arranging that the field windings do not embrace the zones of current reversal on the armature. The converter armature may have a single winding or two separate or interconnected windings. To facilitate starting, a squirrel-cage winding may be provided on the field member, and for high voltages a small starting motor may be employed. The range of regulation may be increased by making the axis of the field winding adjustable with respect to the brush axis. This subjectmatter dons not appear in the Specification as accepted.
