Abstract: 903,686. Washing gas. UNITED STEEL COS. Ltd. Dec. 21, 1960 [Sept. 22, 1959], No. 32262/59. Class 55 (2). Fumes evolved during steel-making and containing iron oxide particles and watersoluble substances, are passed as very fine bubbles into a body of water contained in a vessel from which water is withdrawn, treated by magnetic means to remove suspended iron oxide particles and returned to the vessel. In the apparatus shown in Fig. 1 the iron oxide containing fume enters a vessel 1 through an inlet 6 and is converted into fine bubbles by an impeller, comprising a squirrel cage 3, rotating at high speed on a shaft 4 in a body of water and an outer cylinderical stator 2 made up of tubes. Perforated vanes 12 may be attached to the stator and water to be freed from sus- . pended iron oxide particles is withdrawn at 9 and the clarified water returned at 10. More than one impeller may be arranged in parallel working with a common magnetic device for removing iron oxide particles from withdrawn water. Depressants which preferably also reduce the surface tension of the water may be added to the water in the vessel 1. Additions of sodium sulphite or causticized starch to washing water are referred to.

[Also in Groups XVII, XIX] In a drop safe (see Group XVII) the insertion of an identification token 21 attached to an article B in an aperture initiates a door locking circuit on the completion of which locking a motor is started whereby characters identifying the token are printed on paper strips 30, 31. The token is inserted until a ball and spring assembly 22 engages a notch 21b and the end 21c thereof contacts a switch 61. The shaft 15 rotates and the door 70 is locked. A slider 24, Figs. 1 and 2, is displaced and causes a roller 35 to run along the upper surface of a fixed cam 36 to raise a plate 37 which presses the paper strips 30, 31, Fig. 7, and two layers of printing ribbon 26 upwardly against the token 21 to print identifying characters thereon on to the strips 30, 31, the strip 31 passing beneath the perpendicular to the lower layer of ribbon 26 and the strip 30 passing between and perpendicular to the two layers. The ribbon 26 is displaced by a pawl 45 engaging either a ratchet 46 or a ratchet 47 to rotate spools 27, 29. The ribbon 26 is automatically reversible. The pawl 45 is corrugated to form two depressions 45c, 45d, Fig. 5 (not shown), near its centre and is held in position by a pin 44e engaging in one depression and the pawl end 45a say, engages the ratchet 46 to advance the ribbon 26 until a rivet fixed near to the end thereof contacts pins 44c, 44d. On the next stroke of a fork 43 the pawl 45 forces the pin 44e to be displaced in a slot 44g and the pin engages the alternative depression in the pawl 45 so that the end 45b co-operates with the ratchet 47 to reverse the direction of advancement of the ribbon. Similar reversal takes place when a rivet near the other end of the ribbon engages pins 44a, 44b.

Abstract: 231,573. Bethel, J. N., and Player, S., (trading as Bethel Player Co.). Dec. 31, 1923. Block, rubber, and like apparatus.-Flat articles, for example, piston rings are moved between two stationary laps 11, 12 by a workplate 33 which has a combined rotary and transverse oscillatory motion. The laps are supported on a frame 10 and secured to the frame is a vertical shaft 14 carrying a rotatable member 15, having a central recess. The member 15 is rotated by worm-gearing 16 and in the recess is mounted a pinion 21 secured to the shaft 14. A vertical shaft 2 is mounted in the member 15 and carries a pinion 23 driven by the pinion 21. The pinion 23 has on its lower face a crank-pin 24 which oscilates an arm 25 secured to a vertical shaft 26 mounted in the member 15, the shaft 26 also carrying at its upper end a plate. 27 upon which is slidably adjustable a block 29. The block has thereon studs 31 which engage openings in the work-plate 33; this plate receives the work W in openings located between the laps. The period of oscillation of the block 29 is arranged to differ from that of the rotation thereof, wherebv the path of movement of the work changes progressively with each revolution thereof. Specification 216,684 is referred to.

Title: Improvements in or relating to radio transmitting and receiving systems
Inventor: DUCKWORTH JOHN CLIFFORD
IPC: G01S13/76
Filed: 1946-11-04
Abstract: 639,194. Radiolocation. MINISTER OF SUPPLY. Nov. 4, 1946, No. 32664. [Class 40 (vii)] A radar system comprises at least two aerials of the type which employ mirror reflectors, the reflectors being shaped to produce optimum response at different angles of elevation ; the aerials are rotated and fed in turn, and the received echoes appear simultaneously on one or more cathode-ray tube displays. The embodiment disclosed is an airfield-control radar and has two mirror aerials 1, 2 mounted backto-back on a housing 7 containing the transmitting and receiving equipment, and rotatable about a column 22 on a base 23. Mirror 1 is a paraboloid producing a narrow low-angle beam for long-range detection and mirror 2 a distorted paraboloid producing a high-angle beam suitable for short-range detection with the minimum of ground clutter, the combination of beams providing adequate coverage at all ranges and heights required for airfield control. The transmitter 6 feeds the mirrors alternately through branched wave-guides, each containing a ring switch 8, 9 of the type disclosed in Specification 597,216, the rings being disposed at 90 degrees to each other and rotated by a motor also driving a synchronizing wave-form generator 12 from the transmitter and displays. The generator feeds into a control unit 15 which produces negative locking pulses for the transmitter modulator to ensure that the transmitter pulses with the ring switches in the correct position, and alternate negative and positive pulses to synchronize the display time bases. Displays of the planposition type are employed and polarity discrimination in the synchronizing pulses is necessary since the aerials face in opposing directions and the time bases must be reversed. The aerials function for both transmitting and receiving and employ switching means as disclosed in Specification 583,743. A trolley supports the assembly so that the system may be moved into any desired position relatively to the airfield control tower, the supplies and signals being conveyed by line and connected through slip rings 27 and a rotary coupling 29. The displays are located in the control tower and the received echo signals pass to the displays at the intermediate frequency. A Selsyn motor 32 repeats the aerial bearing to the displays. Preferably the displays have a second rotatable time-base under the control of an independent direction-finding aerial. The second time-base is used to produce a radial trace only on receipt of signals from a transmitting aircraft so that when the second trace intersects an echo on the radar display, identification of that echo with the transmitting aircraft is achieved. The housing 7 includes an air-circulating fan 35 and drying agents 34.

[Also in Division F2] A fluid-pressure operated ram comprises a ram piston 2 in a ram cylinder 1, a damper piston 12 in a damper cylinder 6, and means for moving the damper piston from a position in which it is ineffective to a position in which it restricts the flow of fluid from the exhaust end of the ram cylinder when the ram piston has performed a predetermined portion of its stroke. The ram cylinder is provided with an inlet port 4 and an exhaust port 5 leading to one end of the damper cylinder and an outlet port 8. Fluid pressure supplied through the port 4 moves the ram piston 2 to the left, exhaust fluid passing unrestricted through the ports 5, 8. When the ram piston has moved a predetermined distance, a port 10 in the ram cylinder is uncovered to connect the fluid pressure to a chamber 11 in the damper cylinder to move the damper piston against a spring 15 until a chamfered portion 18 co-operates with a shoulder 19 and adjustable stop 17 to restrict the flow of exhaust fluid from the ram cylinder to reduce the speed and damp the movement of the ram piston.
