Title: Improvements in or relating to portable drill
IPC: B23B47/22
Filed: 1955-08-02
Abstract: 783,820. Portable drilling-machines. ARO EQUIPMENT CORPORATION. Aug. 2,1955 [March 21, 1955], No. 22206/55. Class 83 (3). A portable drilling-machine has a rotary air-motor 68 for driving the drill, the motor being fed axially by a piston 58 on the casing thereof reciprocated within a cylinder 60 by air pressure. A further piston 22 on the motor casing slides within a cylinder 30, separated from cylinder 60 by a wall 40, and acting as a dashpot to regulate the feed of the drill. The rotor 70 of the motor drives, through a hollow shaft 72, gearing 76 by which the drill 80 is rotated. A control valve 64 supplies air through a tube 66 to the motor, and also to the appropriate side of the feed piston 58. Dash-pots.-On forward feed of the drill by air pressure above piston 58, oil in cylinder 30 passes from below piston 22 by a duct 84 and an adjustable needle-valve 94 to a passage 92 above piston 22 to allow the drill to be fed at a pre-set drilling speed, but a rapid approach to the work may be obtained by uncovering one or more ports 42, by adjusting a slide valve 44 so that oil may by-pass valve 94 through ducts 36, 38. The valve 44 is adjusted and set by a knob 46. For the return stroke, air is admitted below piston 58 and the oil pressure above piston 22 opens a valve 34 in the piston to by-pass valve 94 and allow rapid withdrawal of the drill.

Title: Composite metal article containing additive agents
IPC: C21C1/10
Filed: 1975-05-22
Abstract: 1504979 Treating molten metals CATERPILLAR TRACTOR CO 22 May 1975 [15 July 1974] 22326/75 Heading C7D Molten metal is alloyed or treated with relatively volatile metallic materials by feeding into a melt, at a controlled rate, a composite wire-like structure, comprising an inner core 12 of the relatively volatile material, surrounded by an insulating material 14, and both being enclosed in a non-volatile metallic sheath 13. Both the outersheath and the insulating material may contain additional melt additives, and they should both be compatible with the molten metal. Preferably, the insulating material is of particulate form, and should be capable of maintaining the core below its boiling point until the outer sheath has melted in the melt. Examples of the addition of Mg to cast iron or steels in a nodularizing treatment using composite wires with steel sheaths. Mg cores and either Fe powder, Fe powder mixed with graphite, or magnesium and coke powder as the insulating material are given. Variation in the rate of Mg volatilization may be achieved by altering the particle size of the insulant or by pre-heating the composite wire. The wire may be heated by passing through a heated zone or by resistance heating of the sheath to increase the melting rate when large amount of additive are required. Zn, Al or Mu may also be added by this technique.

Title: Improvements in method and apparatus of grading and separating peas, beans, corn andthe like
IPC: B03B5/28
Filed: 1931-08-10
Abstract: 381,654. Washing granular materials. LEWIS, H. R., 309, East Maple Street, Hoopeston, Illinois, U.S.A. Aug. 10, 1931, No. 22620. [Class 82 (ii).] Peas, beans, corn, &c. to be washed or graded are delivered on to the surface of a swirling body of liquid, the materials which float being skimmed off and the heavy materials which sink being carried away up an inclined path to the level of the overflowing liquid. The liquid is contained in an inverted conical vessel 1 provided with a ring 11 having a flared lower part to trap rising air bubbles. Liquid is injected through a pipe 12 to cause a swirling motion in the vessel, particularly in the annular space, formed by the ring 11 and the side of the vessel, to which the peas &c. are delivered by a hopper 13. A skimming plate 15, the lower edge of which can be adjusted to any desired depth in the liquid, intercepts the upper layer of liquid carrying the lighter constituents and directs them out of the vessel 1 on to a screen 17 from which the liquid drains into a tank 4 where it is passed through a sieve to a pump 3 which passes it to a supply tank 2 feeding the vessel 1. The heavier constituents which in their passage round the annular space sink below the edge of the skimming plate 15 fall into a cylindrical extension 5 at the bottom of the vessel 1. The extension 5 receives the liquid from the supply tank 2 through a large pipe 6 entering the extension tangentially and is provided with a discharge pipe 7, also tangentially disposed and of relatively small diameter, through which the heavier constituents are carried to an inclined duct 8. The duct is formed with an upper section 9 adjustable at 10 so that the overflow level in the vessel 1 can be varied. The heavy constituents are delivered on to a screen 19 through which liquid drains into the tank 4. The level of liquid in the tank 4 is kept constant by means of a liquid supply pipe 24 and ball valve 23. The apparatus may be used with brine solution for grading peas or with water for separating peas, berries, corn. &c. from leaves, husks, &c.
Patent GB-1105866-A (GB)
Title: Process for the production of ethylene
IPC: C10G9/16
Filed: 1966-05-20
Abstract: Ethylene is produced from a hydrocarbon feed of a type which on cracking produces primarily ethylene but also yields propylene (e.g. light naphtha, propane or ethane/propane mixtures), by mixing the feed with propylene and steam and thermally cracking the mixture at a temperature of at least 816 DEG  C. in a pyrolysis zone with a residence time of not more than 1 second, cooling the effluent to below 538 DEG  C., separating ethylene product, and also separating propylene and recycling at least part of it to be mixed with incoming hydrocarbon feed.  The amount of propylene mixed with the feed may be up to 25%, e.g. 10-20%, of the total feed (excluding steam).  The process gives improved selectivity for ethylene production and also yields useful quantities of benzene. The pyrolysis zone, suitably a tube, may be periodically cleaned of deposits of coke &c. without cooling, by switching off the feed and recycle propylene streams and allowing steam to pass through alone at a temperature of at least 982 DEG  C.

Title: Multi-cavity klystron
IPC: H01J25/10
Filed: 1974-05-21
Abstract: 1425678 Klystrons NIPPON ELECTRIC CO Ltd 21 May 1974 [24 May 1973] 22711/74 Heading H1D A wide-bond multicavity klystron includes an input circuit section in which a beam accelerating potential is applied across at least one interaction gap, permitting the use of a relatively low Q input cavity; an intermediate bunching cavity circuit tuned to a frequency above the centre frequency of the input circuit band; and an output cavity tuned to that centre frequency. As shown, accelerating potentials E 3  and E 4 -e.g. 1 kV and 4À65 kV, respectively-are applied across the interaction gaps 11 and 15, the drift tubes 4 and 12 being D.C. insulated from, but H.F. coupled to, the respective cavities 9 and 13 by choke structures 10 and 14. The arrangement permits the use of a low Q input cavity 9 fed by a wideband circuit 7. To enhance conversion efficiency, the second and third cavities are detuned by a few per cent above the centre frequency, and bunching is increased by successive shortening of the drift tubes i.e. L3 is less than L2. In a further embodiment, (Fig. 2, not shown) the interaction gap (42) of the second cavity (43), but not that of the first cavity (31), is biased (by E7), and the second cavity is also coupled to a matched load (47) via a wide-band circuit (46), to lower its Q and increase its bandwidth.

Abstract: 746,356. Glass manufacture. OWENS-ILLINOIS GLASS CO. Aug. 9, 1954, No. 23062/54. Class 56 In a machine for forming necks of phials, the glass tube blanks T are conveyed in succession, whilst recumbent and transverse to the line of movement, through a neck-forming zone N, the tubes being raised from the conveying means during the passage through the zone, after which they are returned to the conveying means. This raising of the tubes ensures alignment with internal forming plugs 31 which are mounted on a rotary disc 34 and thus take an arcuate path through the neck-forming zone. The neck is formed externally by a tool 32 on an arm 57. The tubes are moved towards and away from the zone N by fingers 16 on an endless conveyer. and are rotated and partly supported by endless tapes 23 which run counter to the conveyer. They are positioned by a stationary flange 30. After passing the burners 22, the tubes are received between freely rotatable rollers 65 on discs 62 keyed to the shaft 35, and 'are thereby conveyed through the arcuate path. A positively driven belt 68 rotates the tubes during the neck formation which is effected by the plugs 31, and by the tool 32 which is urged by a spring 60 against the phial neck to the extent permitted by a stop 61. The plugs 31 are each carried by a slider 44 which is projected into the glasa tube T by a cam 53 which bears on a roller 52, and is retracted by another cam and by a spring 55. Each guide 38 is adjustable radially, in accordance with the diameter of glass tubing being worked, by a screw 42 and clamping screws 40. The slide 44 carries a head 45 which may shift slightly to accommodate small misalignments between the plug 31 and the tube T. This is permitted by sliding key connections between a disc 48 and the flanged members 46, 47 between which it is positioned. The plug 31 is supported by the member 46 which is connected by a rod 49 to a tension spring 50 whereby the assembly 46-48 is kept together. The clearance between the rod 49 and the bore in the slide 44 limits the accommodating movements of the plug 31.
