Title: A new or improved method and apparatus for removing fuel dilution from lubricating oil of internal combustion engines
IPC: F16N39/00
Filed: 1929-03-19
Abstract: 330,963. Triggs, W. W., (Northwest Engineering Co.). March 19, 1929. Recovering waste lubricants. - Fuel diluents are removed from the lubricating oil of internal combustion engines, by passing the oil through a heated chamber where it is subjected to a stream of air which carries off the vaporized fuel to the engine intake. In a suitable apparatus, oil is withdrawn from the crank case and is passed by a pump 8, Fig. 1, through a pipe 26 to a chamber 10 supported on, and heated by the exhaust manifold 11, said chamber having spaced ribs 15, over which the oil flows. Air is drawn through the jacket 16, surrounding the exhaust pipe 17, and passes through a pipe 19, connected to the upper part of the chamber 10. The oil is caused to flow through the chamber 10 under constant gravity head, by passing the oil leaving the top of the tube 26 through two orifices 27 and 29. Fig. 3, in the fitting 30 so that the excess of oil passing through the orifice 29 over that discharged by the orifice 29 into the chamber 10, overflows through holes 31 and is by-passed up through a tube 32 and pipes 34 and 36 to the crank case. The treated oil leaves the chamber 10, through a T-piece 35, and joins the overflow oil in the pipe 36.

Title: Improvements in or relating to high frequency electrical systems employing wave guides
IPC: H01Q13/04
Filed: 1946-03-22
Abstract: 623,385. Wave-guides ; directive radio systems. PHILCO RADIO & TELEVISION CORPORATION. March 22, 1946, No. 8902. Convention date, Aug. 15, 1944. [Classes 40 (v) and 40 (vii)] In a high-frequency system, a wave-guide 42, Fig. 4, conducting highfrequency energy is coupled to a second guide 41 through a symmetrical arrangement of slots 51 which are driven in phase and in the same sense for exciting the HO1 mode in the second wave-guide 41. The wave-guide is divided into curved sections 44, 45, which straddle the guide 41, the length being chosen so that the diametrically - opposed coupling slots 51 are one half wavelength from the plugged ends 46, 47 of the guide sections. With this arrangement the slots will be excited in push-pull and will generate H01 and H21 waves in the guide 41. The H21 waves are balanced out by an adjustable short-circuiting plate 53 placed at an integral number of half wavelengths of the unwanted H21 waves from the centres of slots 51. Fig. 1 shows a stacked bi-conical horn antenna structure which may be fed with a pure H01 wave from wave-guide 42, coupled as described to a guide 62, linked by a matching section 111 to guide 112 supporting the antenna. The guide 112 is closed at the upper end by an adjustable piston 23 and at the bottom by a plate 53 and constitutes a resonant cavity circumferentially slit as at 31. Metal plates such as 25, 26 complete the bi-conical horns which, when energized by a H01 wave, give a circular horizontal polar diagram. The centre gap 31 may be 15 per cent wider than the outer gaps so as to suppress side lobes.

Filed: 1936-03-26
Abstract: 477,387. Searchlights. SAVAGE, J. C. March 26, 1936, No. 9041. [Classes 75 (ii) and 75 (iii)] For rapidly scanning a large area, the beam from a searchlight is traversed to and fro to different extents and is spread or diverged linearly proportionally to the extent of the traversing movement. In the preferred form, a parabolic reflector 3 projects a substantially parallel beam, an inclined cross-sectional area of which is occupied by a mirror mosaic 4 supported in a frame 5 which is rocked to and fro about an axis 6, the reflectors of the mosaic being angularly adjustable with respect to one another for spreading or diverging the beam linearly. The reflected beam emerges through an aperture 11 in a cylindrical casing 10 which is rotatable about its longitudinal axis by means of an electric motor 22. The mosaic may comprise fixed reflectors 29 and tiltable reflectors 30 made of mirrored glass or highly polished metal. The reflectors 30 are substantially rectangular and are secured by means of screws or the like to blocks or the like 31b (not shown) and to elements 30a hinged or otherwise rotatably connected to members 30b forming part of the frame 5, the hinging or rocking axes 31 being so arranged that they are parallel to the axis of the reflector 3 when the frame is disposed at 45‹ to this axis. Each reflector 30 carries a rod 31a which bears in the parts 30a and 31b and engages an inclined slot in a guide member attached to a beam 33 forming part of the frame 5 and also in a co-operating slot 34 extending longitudinally of a control bar 35 which is pivoted at one end to the frame 5 at 36. The frame 5 is rocked by means of a pivoted link 38, a trolley 39 slidable longitudinally in a frame 40 which is pivoted at 41 on a support 42 and rocked by means of a link 43, a crank 44 and an electric motor 37. The trolley 39 is moved along the frame 40 to vary the extent of the rocking movement by means of an electric motor 45, a shaft 46, a reduction gearing 47, and a slipping clutch 48. For co-ordinating the rocking movement with the linear spread of the beam, the trolley 39 is connected by Bowden wires 50, 51 to the opposite ends of a differential lever 52 pivoted beneath the frame 5, other Bowden wires 53, 54 being connected to the control bar 35. The searchlight may be a fixture or it may be mounted on a vehicle 17 by means of a platform 16 rotatable about a vertical axis 18 by means of an electric motor 19, and gears 20, 21, locking devices 27, 28 being provided to secure the searchlight in its normal position.

Title: Improvements in and relating to septic tanks
IPC: E03F5/18
Filed: 1957-03-19
Abstract: 807,639. Treating sewage. AKERLINDH, G. A. March 19, 1957 [March 29, 1956], No. 9058/57. Class 111. A septic tank is divided by partition walls into a plurality of compartments, at least one of the partition walls having an opening which can be closed by means of a valve or door. Normally the valve or door is kept open so as to permit the sludge, which separates from the waste water entering the tank, to pass from one compartment to another of the tank. But when sludge is to be discharged from the tank, the valve or door is closed in order to retain some of the sludge in at least one of the compartments. The sludge retained serves to inoculate the sludge subsequently settled in the tank and thus to maintain the process of decay or digestion. A pile of stones may be arranged in one of the final compartments so that the water pours, sprays or drips over it, thus facilitating the removal of hydrogen sulphide through the increased contact between air and water. Similar piles of stones may be arranged in some of the other compartments to serve as a surface on which micro-organisms, active in the anaerobic flocculation and decomposition processes, may collect. One of the final compartments may also be adopted for chlorination. In Fig. 1, a septic tank 1 of circular crosssection is divided into compartments 3, 10, 25, 13 and 24, the waste water entering compartment 3 through pipe 26, flowing through the compartments in the order stated and leaving compartment 24 through pipe 23. Openings 6, 11, 16 in partition walls and elbow-pipe 21, 22 permit the flow of the water in turn through compartments 3, 10, 25, 13 and 24, although water may also pass from compartment 3 to compartment 10 over the top of wall 5. Additional openings 14 and 15 connect compartments 25 and 13 respectively with compartment 3. Openings 6, 11, 16, 14 and 15 are all provided with doors operated by bars 8, 18, 17 from outside the tank.

Title: Improvements in a spring brake actuator
Inventor: THOMAS GORDON FREDERICK FRANK
IPC: F16D65/28
Filed: 1963-03-12
Abstract: 1,007,473. Emergency brake mechanism. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. March 4, 1964 [March 12, 1963], No. 9720/63. Heading F2F. A brake actuator for emergencies has means which take up the slack in a braking system without changing the state of its compressed actuator spring before the said spring is permitted to produce a braking force. In Fig. 1 a housing 1 for the emergency actuator is attached to the working brake cylinder 2 which operates a brake rigging rod 19 through a follower 14 and a carrier 17. The housing 1 contains a main spring 5 bearing on a piston 4 in a housing 6 in which is a mechanism 7 wherein balls 8 can be jammed in a coned surface 13 by a spring 12 to lock the piston 4 to the follower 14. The follower 14 is coupled to the carrier 17 by a shoulder 21 which is allowed limited movement between a circlip 20 and a shoulder 22 in a bore 18 in the carrier. A piston 16 on the carrier separates a chamber 24 from the main chamber 10 in front of the piston 4, but the two are connected by passages 28, 29 normally sealed at one end by a valve 23 and spring 25 to permit flow of pressure only through a choke 30 in the valve. An annular piston 9 is subjected to the pressure in the chamber 10 by way of a passage 11 through the housing 6. A port 26 connects the chamber 24 to atmosphere. To charge the actuator a port 26 which connects chamber 24 to atmosphere is closed and pressure fluid is admitted to the chamber 10 through port 27. As pressure rises in chamber 10 it bears on the piston 9 causing it to dislodge the balls 8 from the core 13 thus unlocking the piston 4 from the follower 14. At the same time the pressure leads through the choke 30 into the chamber 24. When both chambers 10 and 24 are at the same pressure the actuator is fully charged. To operate the brake in emergency the port 26 is opened to atmosphere to evacuate chamber 24. Owing to the choke 30 the pressure in the chamber 10 gradually falls, pressure on the piston 9 is also gradually decreased and the balls 8, urged by the spring 12, lock piston 4 to the follower 14. The spring 5 then pushes the piston and follower forward together so that the shoulder 21 engages the shoulder 22, the carrier 17 moves forward to take up slack in the brake rigging 19. At the same time the valve 23 is lifted so that the chamber 10 is completely evacuated and the spring 5 applies the two brakes through the piston 4, follower, carrier and rigging 19. Fig. 2 (not shown), illustrates an embodiment in which, instead of the piston 16 being subject to the pressure in the chamber 10, the end of the cylinder 15 in the chamber 10 is closed and a spring of predetermined strength acts on that side of piston 16. Fig. 3 (not shown) embodies a version of the piston 9 which is operated mechanically and not by pressure fluid.
