Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1930-04-22
Abstract: 353,442. Slicing -machines. FIT Z - PATRICK, H. D., 94, Hope Street, Glasgow. -(Naamlooze Vennootschap Maatschappij tot Vervaardiging van Snij machines Volgens van Berkel's Patent en van Andere Werktuigen;33, Boezemsingel, Rotterdam, Holland.) April 22, 1930, Nos. 12316 and 16576. [Class 28 (ii).] Slice-stacking mechanism for a slicing-machine comprises, in combination, a rotatable rigid conveying structure having slice-engaging elements; a grooved or slotted guide member for pressing the slices upon said elements, and a discharge fly adapted to be moved about a fixed axis by an operative connection with the machine, at a speed independent of the speed of the machine. The rotation of the conveyer may be continuous or substantially continuous, or intermittent or oscillatory. As shown, the slice conveyer 21 is in the form of a segment of a drum and is mounted loosely on the shaft 18 to which it is coupled resiliently by a flexible strip 23 secured to the cam member 20 and engaging pins 24 depending from the conveyer 21. The conveyer 21 is retained on the shaft 18 by a spring latch 22. The shaft 18 is coupled to the main driving shaft of the machine by a shaft 15 and bevels 16, 17. The discharge fly is carried by a shaft 30 arranged transversely to the path of the reciprocating carriage, and the slices are stripped from the tines 25 on the conveyer 21 and thrown towards the operator's position on to the table 41 which is arranged at about the same level as the shaft 30. The discharge fly comprises a vertical bar 31 secured to the shaft 30, and a number of arcuate arms 32 projecting from the bar. The arms 32, during the rotation of the conveyer 21, are positioned behind the slice which has been previously pushed during the slicing, by the grooved or slotted and curved plate 26, against the shoulders on the tines 25. The fly is kept in its vertical position by the part 39 of a tumbler 35 bearing against the cam 20, a roller 37 on the tumbler bearing on a wear plate 38 on an arm 33 on the fly shaft 30. A compression spring 34 tends to swing the fly to discharge the slice, but is prevented from doing so until the part 39 reaches the sudden drop 40 of the cam 20. The tumbler then rests against a rubber stop 42 until it is again restored to its original position by the cam 20. The arm 33 is connected by a link 43 to a brake shoe 44 which rides along a vertical path 45 formed on the casting 19 which also forms the bearings for the shafts 18, 30. The fly is, by this mechanism, given a strongly accelerated movement to ensure correct throwing and deposition of the slices; the speed of the fly being independent of the machine speed. The stacking mechanism is enclosed by a shield coaxial with the shaft 18 and extending from the knife bracket 27 to the table 41. The resilient drive 24 for the conveyer permits the conveyer to accommodate itself to the cutting speed at the slice impaling position.

Title: Improvements in and relating to sulphur recovery
Inventor: MILNER GEOFFREY
IPC: C01B17/04
Filed: 1952-05-16
Abstract: In the production of sulphur by partial combustion of hydrogen sulphide, the mixture of hydrogen sulphide and sulphide dioxide formed being passed through a plurality of stages of catalytic conversion and the reaction product from each stage of conversion being treated for the recovery of sulphur, the concentration of sulphur dioxide is increased before any stage of catalytic conversion by recycling sulphur dioxide recovered from the waste gases so that the molecular ratio of hydrogen sulphide to sulphur dioxide is less than 2.  The sulphur dioxide concentration is preferably increased immediately before the final catalytic stage. The sulphur dioxide is recovered from the waste gases leaving the system by absorption in a medium from which it may be regenerated and is recycled, preferably in an amount equivalent to up to 25 per cent. of the sulphur in the original hydrogen sulphide.  In the drawing pure <PICT:0716264/III/1> hydrogen sulphide is split by flow controller 1 into two streams, one of which passes through a boiler 3 together with air to completely oxidize the hydrogen sulphide therein to sulphur dioxide, which sulphur dioxide rejoins the undiverted portion of the main stream and enters a first catalytic converter 4 at 600 DEG F. The mixture leaving the converter is then passed to a heat exchanger 5 and cooled to a temperature just above its dew point before being admitted to a molten sulphur scrubber 6.  The gases leaving the scrubber 6 are passed through heat exchanger 5 thereby being heated to about 550 DEG F. and passed to the second converter 7.  A stream of sulphur dioxide recovered from the waste tail gases joins the stream of gases leaving the scrubber 6 to enter the converter 7 via heat exchanger 5.  The gases from the converter 7 are scrubbed with sulphur in scrubber 8 and passed to a tower 9 for cooling, and to a leadlined tower 10 containing iron oxide which removes hydrogen sulphide.  The gases from tower 10 then pass to an absorber 11 where the sulphur dioxide is absorbed by dimethylaniline.  The residual gases pass to the atmosphere and the dimethylaniline is regenerated at 13 to free the sulphur dioxide which is passed to the heat exchanger 5 as referred to above.  Specification 716,244 is referred to.

Title: Improvements in or relating to the production of hollow bodies from thermoplastic synthetic materials
IPC: B29C49/04
Filed: 1957-04-16
Abstract: 837,919. Blow-moulding hollow thermoplastic articles. BATTENFELD, W., [trading as BATTENFELD GEB.]. April 16, 1957 [Dec. 7, 1956], No. 12459/57. Class 87(2). Hollow thermoplastic articles, for example bottles, are blow-moulded in a mould which when assembled closes the lower end of a tube of the material hanging between its sections ; the upper end of said tube being closed by a mandrel through which air pressure is applied. Powdered thermoplastic material is forced by a ram into a plasticising chamber 10 and is extruded vertically from nozzle 11 in a plastic tubular form 12. A cutting device comprising two pivoted arms 19 carrying plates with semicircular cutting edges, is raised on rods 13 to a position just below the nozzle 11 and severs the pendant material without altering its crosssection in such a manner that the tube remains attached thereto. Said device is then lowered and the tube guided between the closing halves 40, 41 of a mould. A hollow mandrel 42 incorporating an air injection nozzle is then swung over the upper aperture of the tube and inserted therein and the mould is fully closed ; thus rendering - the tube airtight. After blowmouldiiig the mould is opened and the bottle stripped from the mandrel as it is raised by a lever 45 which is swung into position with the mandrel. The cutting device is first located between the nozzle 11 and the mould with the mandrel orientably supported above its plates. A motor-driven cam plate 23 swings the cam lever 26 which raises or covers the rods 13 in the operational cycle and the cutter arms are actuated by a coarse thread connecting bushes on the rods to the tubular pivots 18, Fig. 5 (not shown), of arms 19. The movements of the hollow mandrel 42 may be cam operated.

Title: Improvements in directive antenna systems for defining a path of electromagnetic wave energy
IPC: G01S1/02
Filed: 1946-04-25
Abstract: 631,662. Aerials. SPERRY GYROSCOPE CO., Inc. April 25, 1946, No. 12526. Convention date, April 28, 1945. [Class 40 (vii)J An aerial system having two partially-overlapping directive patterns comprises two cylindrical concave reflectors juxtaposed end-to-end with a primary aerial element opposite each reflector and flat end walls extending perpendicular to the lengths of and bounding the non-proximate ends of the reflectors which form in conjunction with the edges of the reflectors an aperture, common to the two reflectors. The invention is described as applied to an equisignal glide-path system in which the two overlapping beams are modulated with different frequencies. As shown in Fig. 3, the system comprises two cylindrical concave reflectors 25 and 26 with end walls 23 and 22 and a common partition 24, the two reflectors being energized by wave-guide apertures 33,.34 located at the foci. Reflector 25 is parabolic and produces a symmetrical beam 11, Fig. 1, and reflector 26 has an upper parabolic portion 28 and a lower circular portion, thus producing a cosec<2> beam 10, the two beams overlapping in the vertical plane to define a glide-path, 12, the elevation of which may be adjusted by tilting the two reflectors relatively to each other, Fig. 3A (not shown), or by tilting the combined assembly, Fig. 6 (not shown); in a modification of the latter embodiment the reflectors are so shaped that the aperture is still vertical, Fig. 7 (not shown). Any secondary lobes 13, 13<1> associated with the symmetrical beam 11 are encompassed by the cosec<2> beam 10, thus preventing the formation of false equi-signal lines. The partition 24 does not extend from the concave reflecting surfaces as far forward as the end plates 22, 23 so that the two reflectors have a common aperture, thus ensuring that the horizontal projections of the two beams are substantially coincident, Fig. 2 (not shown). The common aperture may be constricted by the addition to the end-plates 22, 23 of tapered sections 36, 36<1>, Fig. 9 and Fig. 8 (not shown), which serve to match the aperture to the reflectors and to attenuate spurious modes generated at the front edge 43 of the partition 24. The formation of secondary lobes is reduced by adding flared flaps 44, 46. In a modification, Fig. 10 (not shown), the two reflectors are of different height and in Fig. 11 (not shown) half-sections of the reflectors shown in Fig. 3 are employed.

Abstract: 568,213. Turning; machine framings. WARNER & SWASEY CO. Aug. 9, 1943, No. 12854. Convention date, Aug. 25, 1942. [Class 83 (iii)] In a metal-cutting or like machine tool such as a lathe, provision is made for passing a temperature-controlling medium round part of the machine in order to limit variations in temperature which might cause distortion of the machine framing &c. As applied to a lathe, the headstock comprising end walls 40, 41 and front and back walls 36, 38 has outer plates 61, 66, preferably of heat-insulating material, secured in spaced relation to the walls 36, 38 to form passages 62, 67 through which air may be drawn to control the temperature of the headstock. The air enters at apertures 58, 65 at the base of the plates 61, 66 and passes upwards to a space 69 between the headstock cover 48 and a third plate 68 similar to the plates 61, 66, and thence proceeds round the spindle bearings 45, 46 to an interior compartment C of the headstock which forms a sump for the lubricating oil. The air is drawn from the compartment C by a fan 79 driven by an electric motor 73 attached by a flange mounting 77 to the headstock wall 41. The lubricating oil pump 35 draws oil by a pipe 49 from the base of compartment C and discharges it through. a radiator 52 to spray nozzles 57 from which it cascades over the shafts and gearing 30, the air passing over the radiator 52 serving to cool the oil before use. The plates 61, 66 are spaced from the walls 36, 38 by flanges projecting laterally from the latter and rest on steps 60 of the flanges.
