Abstract: 732,634. Spring suspensions; arrangements of wheels and axles. MULTIWHEELERS (COMMERCIAL VEHICLES), Ltd., and MACHRAY, G. Sept. 17, 1953, No. 25724/53. Class 108 (2). In a road vehicle supported by wheels arranged in at least one group comprising a plurality of wheels in tandem on each side of the vehicle frame, each wheel of each tandem group is mounted on an individual short axle which is mounted on its own carrier comprising a rigid bar pivotally connected to the frame by a horizontal pivot which is spaced relatively to the wheel centre (either in front or behind thereof) in the same fore-and-aft relationship of pivot to wheel centre as applies to the other wheel or wheels of the group on the same side of the vehicle, compensating means being provided on each side for controlling relative up or down movements of the wheel centres or of the carriers about the pivots. In the arrangement shown, each of a pair of road wheels 6, 6 at each side of a vehicle frame 1 is carried by a carrier 5 pivoted to brackets 2 and 3 depending from the frame 1. The bracket 3 also pivotally supports a beam 8, which may be a leaf-spring, the extremities of which are connected to the carriers 5, 5 by shackles or slipper bearings. A cushioning device is disposed either between the carriers and the beam 8 or between the beam and bracket 3. Means other than the beam, e.g. hydraulic or mechanical, may be provided to control the movements of the carriers 5, 5.

Convention date, Oct. 19, 1929. Void [Published under Sect. 91 of the Acts]. [Class 35.] A stator has its laminµ of polygonal shape and its axial cooling ducts are located in that part of the core which is outside the circumference of the circle about which the polygon is circumscribed. The diameter of the circle is sufficient to provide sufficient iron within its circumference to carry the flux. In the form shown, the axial ventilating ducts are formed in the corners 9 of the square stator core which is centred on ribs 7 on the stator frame. The stator frame has a central radial rib 8 between which and the core is a small clearance to allow some of the cooling air to travel axially over the stator core periphery. The remaining air passes through axial ducts in the stator and rotor cores, and through the air-gap, the cooling air being drawn by a fan on the rotor shaft through holes in one end shield and exhausted through the other end shield.

In a method of recovering gas from a coke oven, liquor obtained by condensing a component of the gas is ejected through a nozzle into a conduit connecting the oven with the mains. During normal operation of the oven, the liquor is at low pressure, but during charging of the oven the liquor is delivered at a higher gauge pressure, e.g. above 6 kg. per cm.<SP>2</SP>, by a pump which draws liquor from the low pressure main for delivery via a high pressure main to the conduit..Valves on lines from the two mains may be interconnected for synchronous action.

Abstract: 731,230. Centrifugal machines. STANDARD OIL DEVELOPMENT CO. Sept. 24, 1953 [May 22, 1953], No. 26337/53. Class 23. [Also in Group XII] Liquids and vapours are brought into contact in fractionation or absorbing processes &c. by causing a vapour stream to progress spirally through a cylindrical zone and disperse into droplets a liquid stream introduced at a point on the longitudinal axis, the droplets being flung to and propelled along the zone wall and collected as they pass through an opening in it. The angle of swirl of the vapour stream is maintained by at least one set of transverse vanes extending radially from the axis to the periphery of the zone. A mixed vapour and liquid feed is introduced tangentially through a pipe 2 into a fractionation vessel 1 in which superposed tubes 5 . . . 9 provide a succession of contact zones each having near their inlet radial and preferably overlapping vanes which may be flat curved or hollow, for causing the vapour to swirl at an angle of about 30-55 degrees above the horizontal. Condensate escapes over the top of the tubes into annular spaces 15 . . . 19 from which it is drawn off, or some or all may be returned to the preceding zone through downcomers 20, 21, 22, 24; supplementary liquid may be fed through lines 30, 31. In a modification liquid is introduced through the vanes into a hollow hub whence it falls on to a dispersion plate.

[Also in Division H1] The invention concerns a method of manufacture of a monolithic crystal filter having at least three resonators each composed of a pair of electrodes. As shown, there are four resonators formed by electrode pairs 21, 22; 23, 24; 25, 26; 27, 28 coated on opposite sides of a single slab 10 of quartz. The electrodes 21 . . . 28 are connected, respectively, to terminals 1 . . . 8 through coatings such as 30, terminals 1, 2 being connected to the filter input and terminals 7, 8 to the output. In the method of manufacture the resonant frequency of each resonator is measured and the thickness of the respective electrodes is gradually increased until the desired characteristic is obtained. In practice, it is difficult to obtain exactly the necessary electrode thickness and to facilitate the making of the intermediate resonators formed by electrode pairs 23, 24; 25, 26 these electrodes are deposited to a thickness which gives a resonant frequency characteristic higher than that required. The required resonant frequency is obtained by connecting a variable capacitor (Fig. 4, not shown) across each of the terminal pairs 3, 4 and 5, 6 and by adjusting the capacitor.
