Filed: 1941-04-28
Abstract: 548,763. Fuel-injection pumps. SOC. ANON. A. SAURER. April 28, 1941, No. 5474. Convention date, May 7, 1940. [Class 102 (i)] In a fuel-injection pump for internal combustion engines in which all the pump elements are housed in an undivided casing 1, the cylinder 10 is put in and pressed down from the end remote from the cam shaft 2, and in which the piston 9 is pressed by a return spring 11 against a plunger 6 which operates in a partition between the cam shaft and the spring chamber which is provided with a lateral aperture 27, the connection between the piston and the spring is releasable from the lateral opening without rotating the piston, whereby the piston and cylinder are removable from the end remote from the cam shaft, whilst the other parts are removable through the lateral aperture. The latter is closed by a readily releasable cover 28. The lower end of the spring 11 bears directly against a plate 29 carried by a plate 31 which has a radial slot, whilst the plate 29 and the upper spring plate 34 are both flanged at 39, 40 to engage between the flanges 37, 38 of an assembling and releasing sleeve 36 when the piston is in its uppermost position, and the spring compressed to its minimum length. The pressure valve assembly 22 being previously removed, a bolt is screwed into a threaded hole 35 in the upper end of the piston and the latter pressed downwards to free the slotted plate 31 so that it can be removed laterally. By pulling upwards on the draw-off bolt, the driving connection 16 on the piston rod 32 engages the cylinder 10 and the two are withdrawn upwardly. In one modification the slotted spring plate is arranged within an annular unslotted plate and rests on the collar 33 of the piston rod so that it is pushed out by a shoulder on the piston rod when the unslotted plate is raised by the releasing sleeve 36. In a second modification, a one-piece slotted lower spring plate has two segments cut away from its rim to enable the spring to be grasped and the plate drawn out laterally. The Specification as open to inspection under Sect. 91 comprises also a third modification in which one or more driving projections on the piston rod engage in corresponding grooves cut in the regulating sleeve 12 and the bore in the casing 1. This subject-matter does not appear in the Specification as accepted.

Filed: 1962-02-13
Abstract: 931,385. Developing films. D. TELSON. Feb. 13, 1962, No. 5537/62. Class 98 (1). A package comprises a radiation-sensitive film (e.g. X-ray film) completely enclosed in a container which is opaque to light but waterpermeable, between the film and the container is a barrier comprising a plurality of spaced elements so as to permit the passage of liquid therethrough, the material of both barrier and container being transparent to the said radiation. Fig. 1 shows the separate components of one form of the invention. The film sheet 16 is placed inside a folded barrier sheet 12 of vinyl coated fibre-glass, and this assembly then inserted into an outer container envelope having a flap 11, so that the entire interior of the container is light-tight. A preferred material for the container is black filter paper. The film sheet may be exposed to X-rays in situ within the container, which is then immersed in a bath of developing liquid. This penetrates through the permeable envelope 10 and circulates freely round the film, which is kept by the barrier sheet from coming into contact with the envelope wall. Washing and fixing may be carried out in a similar manner. An additional barrier of limp water-pervious material such as cheesecloth may be interposed between the fibre-glass barrier and the envelope. In a modification (Fig. 6, not shown), the barrier is formed by coating the inner surface of the envelope with separated particles of a suitable plastic.

Abstract: 1,263,401. Crystal growth. UNITIED AIRCRAFT CORP. 6 Feb., 1970 [13 March, 1969], No. 5777/70. Heading B1S. [Also in Division B3] Double-orientated single crystal castings are directionally solidified in a ceramic-walled mould 10 having article-forming cavities 22 opening via constrictions 26 and ceramic tubes 30 (having 90 bends therein) into a solidification controlling cavity 16. The tubes 30 open adjacent and normal to one 13 of at least two chill plates 12, 13 with chill surfaces at angles to one another. In operation, the mould is preheated and alloy poured to fill cavities 16 and 22. Chilling is started resulting in dendritic growth perpendicular to both chill plates. Dendritic growths orientated in two directions growing into the ceramic tubes 30 are selected by the right-angle bend to grow upwardly into the article--forming cavities as upward solidification is effected. The constrictions 26 select single crystals to grow upwards into the article-forming cavities. The arrangement shown in the figures results in the [001] axis of the crystal being orientated along the vertical axis of the article-forming cavity. To obtain other axes of the crystal orientated along the article cavity vertical axis, one of the chill plates and the ceramic tubes are placed at oblique angles to the horizontal.

Title: Improvements in or relating to potato harvesting machines
IPC: A01D17/16
Filed: 1942-12-28
Abstract: 563,694. Potato harvesters. PACKMAN, P. J., and WHATLEY, L. H. Dec. 28, 1942, Nos. 5844/43 and 749/43. Divided out of 663,680. [Class 6 (iii)] A potato harvesting machine comprises in combination a wheeled carriage having means for lifting potatoes and stones and for separating them from the earth lifted with them, a discharge shoot for the potatoes and stones directed rearwardly of the carriage, a gap in the shoot at a position intermediate its length, and a rotary brush disposed beneath the gap on an axis transverse to the length of the shoot. In the construction shown, potatoes from a riddle 25 are conveyed by buckets 34 in an elevator 32 to a shoot comprising an upper portion 35 and a lower portion 50. In the gap between the two portions is a rotary brush 45 and a chat separator 46, both of which have associated with them canvas baffles 70 under which the potatoes pass. The wire, bristle, or other tufts of the brush are such that whereas they will support potatoes and help them to bridge the gap when the brush is rotated, denser material such as stones will drop into spaces between them and will thus be delivered to a hopper 56 leading to a shoot 57. Chats. pass through the separator 46 to a sack supported by a member 63, the separator comprising a series of fingers, alternate ones of which are at an angle to the plane of the shoot as shown. A pivoted baffle board is.fitted in,the lower portion 50 to direct the potatoes into either of two sacks suspended from hooks 60 and supported by supports 61. According to the first Provisional Specification, the brush is dispensed with and the separation is effected by the provision of the gap alone or, alternatively, by a series of spaced parallel springs upon which potatoes will bounce, but through which the stones will force themselves. The springs extend in the direction of the travel of the potatoes and may be in the form of lengths of spring wire or of closely coiled helical form.

Title: Improvements relating to apparatus for distributing finely divided materials
IPC: F27B9/18
Filed: 1939-02-23
Abstract: 525,614. Charging rotary furnaces. JORGENSEIN, M. VOGEL-..Feb. 23, 1939, No. 6077. Con-. vention date, Feb. 24, 1938. [Class 51 (ii)] [Also in Group XXX] Materials are transferred in a stream of substantially uniform thickness from a jigging conveyer to a surface moving transversely thereto by a deflector. The application to the distribution of materials on a rotary grate, such as that described in Specification 404,018, is shown in Fig. 1. The raw materials pass from a pug mill 50 into a trough 43 through an elongated opening 48. The trough is contained in a casing 30 which is supported by pivoted arms 32 and is reciprocated by an eccentric 38. In order that the casing may be withdrawn from the grate 15 when desired, the lower ends of the arms are attached to beams 33 having flanged wheels 34 movable on tracks 35. At the discharge end of the trough the material is directed through an opening 55 by a pair of adjustable plates 56, Fig. 2, and falls on to a comb 61 which directs it on to the grate. The opening is covered by a hood 59, Fig. 3, from which the teeth 61 incline downwardly in the direction opposite to that in which the bottom of the grate moves. The finer particles pass through the comb and are deposited on a layer of the coarser particles. The materials, after being carried by the grate through substantially a complete revolution, fall into a trough 21 containing a screw conveyer 26 which transfers them to a shoot 27 leading into the main compartment of the kiln: The bottom of the trough forms the top of a chamber 45 through which hot gases are drawn from the interior of the grate. Escape of gases from the kiln through the trough is prevented by a flexible flap 62. Hot gases from the kiln, which have passed through the grate and the material on it into the space between the extension 13 of the kiln and the grate, pass through openings 18 into a ring 16, and thence to a hood 19 connected to an' outlet 20.

Abstract: 1,203,534. Dehydrating gases; concentration of water-absorbent liquid. BLACK, SIVALLS & BRYSON Inc. 5 Feb., 1969 [5 Feb., 1968], No. 6230/69. Headings B1B and B1L. Gas streams to be dried, e.g. natural gas, enter column 10 (see Fig. 1) by line 11 and pass up through trays 12 in counterflow to moderately concentrated dehydrating liquid, e.g. triethylene glycol, which enters at an intermediate point of the column by line 14. The partially dehydrated gas then rises through chimney tray 13 and through a further succession of trays 12 in counterflow to highly concentrated dehydrating liquid which enters by line 18, the substantially dry gas leaving by line 19. The water-rich effluents from the two sections of the column leave by lines 15 and 22 and are combined in line 23. They then pass through heat exchanger 25 (see Fig. 2), line 26, and heat exchangers 28 and 29 before entering packed section 32 of still column 24 through line 31. The liquid phase then enters vessel 30 containing heater 34 through opening 35, moderately concentrated liquid therefrom leaving through pipe 36 and exchanger 29 to be returned to column 10 by line 37, pump 37A and line 14. The rest of the liquid in vessel 30 leaves through packed conduit 38, up through which passes a hot gas stream, suitably a heated portion of the dry effluent from line 19, which enters by line 40. Water vapour leaves the system through 35. Concentrated liquid is collected in accumulator 27 and recirculated therefrom by line 41, pump 42 and line 18 to the upper section of column 10.
