Title: Improvements in and relating to the suspension of vehicle bodies
IPC: B60G13/06
Filed: 1938-04-13
Abstract: 492,881. Vehicle spring-suspensions; dashpots. JUNKERS FLUGZEUG-UNDMOTORENWERKE AKT.-GES. April 13, 1938, No. 11364. Convention date, April 13, 1937. [Classes 103 (vi), 108 (ii), and 108 (iii)] In a rail or road vehicle suspension of the kind in which the body is supported upon a bolster or cradle, the lateral movements of the latter are resisted by rubber springs, gravity or other substantially frictionless means in combination with a damper that permits a relatively free movement of the bolster &c. from its central or normal position and damps the return movement only until the central position is reached, i.e. permits a partially damped oscillatory movement. In the construction shown diagrammatically in Fig. 1 a cradle or bolster 1 is supported in the frame or chassis 2 by means of cylindrical rubber elements 4 which are stressed in shear by the lateral displacements of the cradle 1, a hydraulic damper 6, 7 operating in the manner referred to being disposed between the cradle and a frame element 5 enclosing the rubber 4. Other arrangements are described in which the cradle is supported by spiral steel springs, or by torsion bars, or by cantilever plate springs, or, as shown in Figs. 8 and 9, the cradle 1 may be borne upon rollers 20 or 21, while its lateral movements are resisted by horizontal helical springs 23 or by gravity. Dashpots. A suitable damper or dashpot comprises a cylindrical casing 31 filled with oil and fitted with an annular piston 32, which is guided on a hollow guide rod 39 and has a piston rod 35, the lower portion 37 of which is formed as a sleeve having a number of apertures 38. The guide rod 39 is provided with upper and lower openings 44<1>, 45<1> controlled by ball valves 44, 45, with upper and lower fine passages 46, 47, and with two intermediate openings 42, 43, which coincide respectively with the upper and lower edges 48 of the piston 32 when in its normal position. In any displacement of the piston from the central position oil flows relatively freely into the interior of the rod 39 past the ball valve 44 or 45, and thence via the opening 43 or 42 to the other side of the piston, but in the return movement the valve 44 or 45 closes and the fine passage 46 or 47 restricts the flow. In order to limit its outward movement, the piston is adapted to seal one or other of the openings 44<1>, 451, which are formed with tapering side channels 50, 51 so as to produce a gradually increasing cushioning effect. The upper portion 53 of the piston rod 35 is filled with air under pressure. In a modification, Fig. 12 (not shown), a solid piston rod is employed, passages equivalent to 42, 43, 44<1>, 45<1>, 46 and 47 communicate with a duct in the casing wall, and the upper and lower ends of the casing are connected by a second wall duct.

Title: Improvements relating to signalling lamps
IPC: G08B5/38
Filed: 1941-09-13
Abstract: 565,051. Signalling by visible signals. ALDIS BROS., Ltd., and ALDIS, A. C. W. Sept. 13, 1941, No. 11748. [Class 118 (ii)] Relates to a shutter for attachment to a signalling lamp to enable successive flashes of two different colours to be transmitted. According to the invention, the shutter comprises a pair of similarly apertured discs which are oscillated about a common axis, one of the discs being actuated by the signaller while the other disc is given an opposite movement by an over-centre spring mechanism that interconnects the two discs. The shutter comprises an annular casing c, Fig. 1, which fits over the front of the signalling lamp a, the normal front z of the lamp being used as the front of the casing. The casing contains a colour-screen disc h which is rotatably mounted on a short shaft g and is provided with a, finger piece by which it can be turned to any one of three different positions. The disc is formed with segmental apertures p, Fig. 4, each of which contains translucent panels q, r coloured red and green, respectively, and an aperture p through which light passes is formed between each of the segments. The shutter consists of a pair of discs 3, 4 both rotatably mounted on the shaft g in close proximity to one another and to the disc h. The disc 3 is formed with a circular group of apertures 5, Fig. 5, and the disc 4 is formed with a similar group of apertures 6. The disc 3 is provided with a thumb piece 7 which enables the signaller to oscillate it while holding the lamp a in his hand. The second disc 4 is connected to the disc 3 by any suitable overcentre spring mechanism, such as a pair of swivel pieces 13, each of which engages a pin 14 on one of the discs, one of the frames 13 being provided with rods 15 that slide through the other swivel frame and are surrounded by compression springs 16. Thus, when the disc 3 is moved by the thumb piece 7, the springs 16 are first compressed and then, as the disc passes its mid-position, they expand and move the disc 4 in the opposite direction to a limit imposed by a stop 17. The extreme positions of the discs are so arranged that the apertures 5, 6 register and transmit light of one colour only, the particular colour being determined by the position of the disc h. During the opposite movements of the discs, the light from the lamp is interrupted so that there is a complete eclipse of one coloured flash before a different coloured flash is emitted.

Title: Improvements in or relating to hot-gas reciprocating engines and refrigerating engines and heat pumps operating on the reversed hot-gas reciprocating engine cycle
IPC: F02G1/05
Filed: 1952-05-09
Abstract: 730,098. Hot gas engines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 9, 1952 [May 12, 1951], No. 11777/52. Class 7(1). [Also in Group XIII] The invention relates to supplying working medium to and withdrawing it from the working space or spaces. In Fig. 1 a working space is indicated diagrammatically by the reference 1. When a piston valve 11 is operated working medium can flow from a reservoir 3 to the working space 1 during the part of the engine cycle in which the pressure is lower than that in the reservoir. Similarly a valve 12 controls the discharge of the working medium. The valves 11, 12 may be controlled by an engine regulator. A compressor 19 may be used to increase the pressure level in the reservoir. A connection 22 to atmosphere may be provided. In Fig. 3 a pipe 43 leads to an engine working space not shown. When a cap 60 is operated to increase the pressure of a spring 61 a valve 48 is opened and working medium is supplied to the pipe 43 from a reservoir 56. The pressure acts inside a bellows 51 and when the pressure has risen sufficiently the valve 48 is closed. To release working medium the cap is operated to relieve the spring pressure and a valve 49 is opened through a connection 57, 63. The medium can thus discharge to a reservoir 70. The release of medium decreases the pressure in the space 50 and the valve 49 closes again. The reservoirs are interconnected by a reducing valve 72. Working medium can be supplied by a compressor 73. In the case of multi-cylinder engines each working space may be connected to pipes corresponding to the pipes 44, 45 through non-return valves. Two control valves may be provided coupled together these valves having a common operating device which is responsive to and indicates the mean pressure in the working chamber of the engine.

Abstract: 1375909 Hydrocarbons MOBIL OIL CORP 14 March 1972 [14 April 1971] 11780/72 Heading C5E A mixture of the three isomeric xylenes with ethylbenzene is separated into its components by:  (1) treating with an adsorbent to separate paraxylene and ethylbenzene from the other two xylenes; (2) crystallizing the paraxylene from the mixture with ethylbenzene and then distilling the mother liquor to recover ethylbenzene; and (3) distilling the mixture of metaxylene and orthoxylene to separate them, or distilling this mixture to separate metaxylene and orthoxylene only in part and then diluting the residue with toluene and isomerizing it to obtain additional paraxylene, and recovering this by adsorption. Bottoms from the distillation of ethylbenzene may be recycled to the crystallization step, and bottoms from the second adsorption step may be recycled to the second distillation step to recover further orthoxylene and metaxylene. The preferred adsorbent is zeolite ZSM-5 (see Specification 1,161,974), and desorption may be by reduction of partial pressure of the adsorbed material or of total pressure, by purging with an inert gas, by heating, or by a combination of these. The isomerization may be at a temperature of 250‹ to 1000‹ F. over a zeolite catalyst, e.g. zeolite X, zeolite Y, mordenite or ZSM-4.

Filed: 1955-04-23
Abstract: 838,774. Electric grills and hot-plates. SIMPLEX ELECTRIC CO. Ltd. April 23, 1956 [April 23, 1955], No. 11791/55. Class 39(3) In a cooking appliance involving downward heat radiation, e.g. for grilling or toasting and having open wire heating resistors 30 occupying a plate-like zone as a grid separated from a lower cooking space by a wire frame guard 14 permeable to radiant heat, the heating wires 30 are carried by refractory insulating supports or eyelets 36 mounted on or supported by the guard 14, so as to be spaced apart from each other, each support affording such a low rate of heat extraction and such a small degree of shading as not to impair the radiant heating performance. The guard 14 comprises a rectangular wire frame 15 with transverse and longitudinal wires welded thereto carrying wires or tabs engaging grooves or slots in the flat ceramic eyelets 36. The heating element is mounted beneath a flat flanged metal plate 11 forming a hot-plate, the guard 14 having projections 18 entering holes in the flange and having welded thereto at the other end a flanged apertured mounting plate 19 through which project contact pins 22 and an earthing pin 23 projecting down from a housing 13 at the end of the hot-plate 11 formed integrally therewith. The plate 19 is held by a nut 26 on the earth pin which is screwed into the housing 13 and is connected to the guard by a metal strap 26. The heating wire 30 is a wire, normally a helical coil, and may be in two parts as shown in Fig. 1 and arranged to give more heat at the corners either by forming the helix into unclosed loops 31 open to the axis of the heater or by forming it in the corners as a coiled coil. The clips attaching the eyelets 36 to the guard 14 may be wires 37 of U form as shown in Fig. 2 engaging continuous or discontinuous grooves in the periphery of the eyelet. The clips may be welded to the guard. The lower part of the eyelet may be rectangular to seat on the mesh of the guard, to which a wire is welded and is bent over the groove of the eyelet; or a continuation of a transverse wire 28 of the guard is bent up and over into the groove. The eyelets may be rectangular with lower lateral integral flanges. 48 (Fig. 7) and slots 49 into which project metal strips 50 welded on the guard, side tongues 51 of the strips 50 being bent over the flanges. Although the underside of the hot-plate is normally free from projections, it may be formed with flat downward projections with open-mouthed slots fitting over the eyelets and pressing them on to the guard. The resistor may be wound into a helix on a mandrel having a diameter equal to that of the wire, e.g, 0.0253 inch and when released, the diameter of the coil is 3-5 times that of the wire. The coiled coil of wire is made by winding this helix on a mandrel equal to outer diameter of the helix. Specification 838,775 is referred to.
