Title: Method of firing gas and like retorts
IPC: F23D99/00
Filed: 1930-03-11
Abstract: 350,960. Retort furnaces. ILLINGWORTH, S. R., Fernwood, Radyr, Glamorganshire, and ILLINGWORTH CARBONIZATION CO., Ltd., 16, Kennedy Street, Manchester. March 11, 1930, No. 7947. [Classes 51 (i) and 51 (ii).] In the firing of a battery of gas or like retorts the heating gases from the first retort of a series are passed through the settings of succeeding retorts, and the required temperature is maintained by supplying additional heat between the settings, either by passing the gases through a heater, or by adding fresh combustion products. Preferably the heating gases will be taken off to the main exhaust after passing through a small number of settings, say six, instead of passing the whole length of the battery. In the plant shown diagrammatically in plan in Figs. 7 and 8 the retorts are grouped in sixes, and the half walls of the settings are independently fired. Additional gases are supplied at the connections b and between the fifth and sixth retort of each group a flue k fitted with an exhaust fan leads to the main exhaust flue l. As the quantity of heating gases increases along each group the flues of the fifth and sixth retorts may be fed in parallel as shown in Fig. 8. The last retort of the battery may be independently heated with reversible flow of the heating-gases. The gases from the mains l may be utilized in a waste heat boiler. In adapting an existing setting, adjacent heating walls are connected in series by the flues s, Figs. 9 and 10, and additional heating-gases are supplied by the burners x, x<1>, x<2>, x<3>, t, t<1>, t<2>, t<3>, Resistance to flow in the flues may be reduced by fitting curved plates c, Fig. 4, where the direction of flow is reversed, and sleeves d at the joints. Specifications 244,505 and 244,837, [both in Class 51 (ii), Furnaces and kilns for applying &c.], are referred to.

Title: An improved method of and machine for washing clothes and like articles
IPC: D06F17/00
Filed: 1950-03-31
Abstract: 683,909. Washing-machines. LIGHTBOURNE, R. C. March 29, 1951. [March 31, 1950; Nov. 23, 1950] Nos. 8078/50 and 28618/50. Class 138 (ii). [Also in Group XXIV] A method of washing clothes and like articles comprises circulating the washing liquid within a container for the articles and in a closed vortex which is substantially symmetrical in relation to the centre of the container and subjecting the liquid vortex to sudden changes in direction so as to obtain relative movement of the liquid in relation to the articles to be washed. A machine for carrying out the method consists of an impeller 16 contained in a recess 14 in the base of a tub 11 rotated undirectionally through a clutch 24, 29 and a belt driven by an electric motor 52. Two vanes 61 mounted diametrically opposite each other on the side wall of the tub produce the sudden changes in the direction of the vortex produced by the impeller. The impeller consists of a hollow shell 17 having perforations in its top 18 and periphery 19 and having a plurality of radial vanes on its underside connecting its peripheral wall with a central boss ; washing liquid is drawn in through the top perforations and discharged by the vanes through the peripheral perforations. The clutch comprises a driving member 29 connected to a shaft 31 which is belt driven by the motor 52 and a driven member 24 on which the impeller rests and which can loosely rotate on the end of the shaft 31. The impeller is connected to the member 24 by projections 27 on the member which butt against the vanes on the underside of the impeller. When the clutch is disengaged the member 24 engages and rests upon a ledge 15 in the recess 14 which acts to brake the rotation of the impeller. The clutch is operated by sliding the shaft 31 axially, the upper end of the shaft being journalled in a slidable bearing 37 and the lower end being connected by a thrust bearing 38 with a slidable rod 39 which is connected through linkage with an operating handle 49. The clutch slips if clothing becomes entangled with the impeller to prevent the clothing being damaged. The tub is drained when desired by a pump (not shown) which is continuously driven from the motor 52. The pump inlet in the tub bottom is normally closed by a manually operated discharge valve. Specification 683,910 is referred to.

Title: Improvements relating to devices for indicating the maximum value of a variable force
IPC: G01L7/06
Filed: 1951-04-09
Abstract: 686,887. Pressure gauges. SULZER FRERES SOC. ANON. April 9, 1951 [Jan. 18, 1951], No. 8239/51. Class 106 (ii). A device for indicating the maximum value of a variable force comprises a non-rotatable piston 12, Fig. 1, movable by the force against a spring 16, the piston 12 having an axially extending arm 17 threaded at its end into a nut 20, the arm 17 and the nut 20 forming a normally reversible worm and nut mechanism so that an axial pressure applied to the worm can cause the nut to rotate, if free to do so. The nut 20 is capable of only limited axial movement and is normally in engagement with a fixed seating 15. Whenever the spring 16 is compressively displaced by a further amount, the nut 20 is lifted from its seat 15 and rotates to allow the arm 17 to pass therethrough, the amount of such rotation being indicated by a head 21 rotating with the nut 20 and acting as a scale relatively to a fixed mark 23. When the compressive action on the spring 16 ceases to increase and tends to decrease, the nut 20 engages its seat 15 and locks the worm and nut mechanism to prevent a return movement of the parts. The upward axial movement of the nut 20 is limited by a thrust bearing 26 carried by the nut 20, the bearing 26 engaging an upper end member 28 when the nut 20 is sufficiently displaced. The bearing 26 is such as to allow the nut 20 to rotate freely. The piston 12 is prevented from turning by two pins 13 sliding in slots 14 in the device. In Fig. 2, balls 30 are disposed between the nut 201 and the threaded arm 17<SP>1</SP> to decrease frictional resistance. Also, the spindle 17<SP>1</SP> and the spring 16<SP>1</SP> are housed in a pressuretight bellows 31 to ensure that the pressures to be measured act only on the underside of the piston 12<SP>1</SP>. The provision of a weak spring 32 acting downwardly on the nut 20<SP>1</SP> ensures that a rapid locking of the nut 20<SP>1</SP> will occur at the instant after attaining maximum pressure. The worm element 17 of the worm and nut mechanism may be a rod of non-circular cross-section twisted helically about its own axis and co-operating with a correspondingly shaped aperture in the nut element 20.

Abstract: 746,320. Hydraulically operated fastenings. CATERPILLAR TRACTOR CO. March 22, 1954 [Dec. 30, 1953], No. 8277/54. Class 44. [Also in Group XXI] The control mechanism of a fluid-actuated latch 25, positioned on the draft frame of an earth-moving, bowl-type scraper, is so designed that the latch normally permits of the passing of the bowl 10 in an upward direction, but not in a downward direction, so that, in the event of failure of the bowl-raising mechanism, the bowl cannot drop suddenly into contact with the ground. Fluid, e.g. air, under pressure acts on a diaphragm 29 in an assembly 28 to cause a linkage 30, 31 having a spring-biased, lostmotion connection 34 to maintain the latch in a position in which it would be below a hook 32 on the bowl 10 when raised. The latch can be withdrawn on venting the pressure chamber 27 of the assembly 28 to atmosphere. The fluid under pressure is supplied to chamber through a pipe 36 forming the central core to the control lever 23 of the bowl-raising means, a port 37, ports 38, an annular passage 39 and port 40 in which is connected a flexible pipe 26. The latch 25 is withdrawn by depressing a plunger 45 incorporated in the lever 23 to force a spring- loaded valve 35. to close port 37 and vent chamber 37 to atmosphere through ports 46, 47.

Title: Improvements in the art of bitumen road making
IPC: C08L95/00
Filed: 1936-03-21
Abstract: In the production of bituminous road material from aggregates of acid character, the aggregates are treated, prior to adding the bituminous binder, first in the presence of water with a basic metallic compound capable of chemically attacking their surfaces and of forming soaps practically insoluble in water with saponifiable substances, and after the chemical attack with a saponifiable substance.  This treatment is stated to improve the wetting of the aggregate by the bitumen binder and to render the bond highly resistant to water. Aggregates specified are granite, gravel, sand or other mineral substances rich in silica.  A test for determining whether the surfaces of the aggregate have been attacked by the basic metallic compounds is described.  Basic metallic compounds specified are oxides or hydroxides of aluminium, or magnesium or calcium or other alkaline earth metals; these materials may be added as a powder to moist aggregates or as a solution.  Saponifiable substances specified are oleic acid, fatty acids and glycerides thereof, and resins such as rosin; the substances may be added to the aggregates as an aqueous emulsion or as a solution in organic solvents such as benzine, benzol or petroleum.  Bituminous binders specified are tar, asphalt and mixtures thereof; the binders may be applied molten or dissolved in solvents such as light petroleum.  Before or after the addition of the bitumen to the aggregate, the aggregate may be treated with a solvent for the bitumen such as petroleum, benzine or benzol. The invention may be applied to the treatment of road surfaces in situ.
