Abstract: 878,700. Differential gear; ratchet clutches. FERGUSON RESEARCH Ltd., HARRY. March 22, 1960 [April 15, 1959], No. 12717/59. Class 80 (2). [Also in Group XXXI] A vehicle transmission system comprises an engine driving differential gears for front and rear axles through a reversing gear and a controlled differential having two one-way clutches. Each clutch has a running and an overrunning member such that the running member of one and the overrunning member of the other rotate with the differential input member, the other two members rotating with a propeller shaft. Between each pair of clutch members are a friction clutch and a co-operating presser with a helical connection to one of the members and an hydraulic abutment such that hydraulic liquid may be released rendering the abutment inoperative and disabling the clutch. In the construction shown in Figs. 1 and 2 drive is transmitted from the engine by chain 13, toothed wheel 14 and epicyclic reversing gear 4-7 to differential input member 1. Planet carrier 5 may be moved on splines 6A by lever 9 on reversing shaft 9A to give forward gear when planet wheel 5A meshes with teeth 6A on sleeve 12 and 4A an annulus 4, reverse when gear 5B on the planet carrier engages a fixed ring 7A and neutral in the intermediate position. The differential unit drives propeller shafts 10, 10A to the front and rear differentials. Shaft 10 has a gear 20 on it which drives a parallel hollow shaft 22 which forms the inner members of the two one-way clutches. An extended sleeve 11 attached to the differential input member 1 surrounds shaft 10 and has four gears on it, 23, 25 meshing with gears 24, 26 on shaft 22 which form part of the outer members 30, 31 of the two one-way clutches. As gear 23 is larger in diameter and gear 25 smaller than gear 20 member 30 overruns shaft 22 but shaft 22 overruns member 31. The clutches also comprise pressers 32, 33 on helical threads such that the drag of friction plates 60, 62 when overrunning keeps them apart but should excessive differential action occur, as when a wheel spins, the running member will no longer be overrun and the presser will move inwards on the helical thread and push the friction plates 41 against an abutment 40 to limit the differential action. Normally the abutments 40 are held by hydraulic fluid in the chamber 45 between them, but the pressure may be released by cable-operated lever 72 in which case the movement of the pressers is limited by shoulders 63 on shaft 22. An interconnection between the reversing gear and lever 72 may be fitted to ensure that the one-way clutches are rendered inoperative for travelling in reverse

Abstract: <PICT:0882644/IV (b)/1> <PICT:0882644/IV (b)/2> The continuous catalytic alkylation of hydrocarbons is effected by introducing a liquid mixture of alkylatable hydrocarbon and alkylating agent at high speed into a vertically elongated reaction zone (18) containing a liquid alkylation catalyst as the continuous phase, passing the reactor effluent into a settling zone (2) positioned above the reactor and in open communication therewith, separating hydrocarbons and the catalyst which latter passes (by line 14) to a cooling zone (16) openly communicating with the lower end of the reactor; the catalyst circulates solely by the energy imparted by the flowing hydrocarbons and density and temperature differences.  The numerals refer to Fig. 1; in a preferred embodiment there are two reactors each having an associated cooling zone and rising to a common settling zone.  The latter preferably contains a zone 4 to aid settling comprising one or more perforated baffles or one or more series of horizontal and/or vertical plates (26) whose width is (a) 1-4 times the distance between them and (b) 1/10 to 1/50 of the total length of the settler.  More than one set of such plates may be employed provided the sum of their widths is within these limits. The means for injecting the hydrocarbons is illustrated in Fig. 5, the hydrocarbon enters by tube 20 and flows through plurality of pipes 32 within the cooling zone 16 at 10-150 feet per second; the hydrocarbons draw up the cooled catalyst into the reactor 18.  The catalyst may be hydrofluoric, sulphuric or phosphoric acid or aluminium chloride or bromide.  Paraffins or aromatic hydrocarbons may be alkylated with olefins, alcohols, ethers or esters, in particular, isobutanes may be alkylated with ethylene butanes or pentenes, the latter being in an excess up to 20 : 1 mol ratio. Other conditions may be =40 DEG F. to 150 DEG F., atmospheric pressure to 1,000 p.s.i. and space velocities of 0.1-20.

Abstract: 868,872. Photographic cameras. AGFA A.G. April 16, 1959 [April 24, 1958], No. 13041/59. Class 98(1) In an objective assembly for a photographic camera which includes a pre-setting diaphragm and an automatic depth of focus indicator, mutually separate means are provided for controlling the diaphragm and the depth of focus indicator and both of said means are controlled by operation of the diaphragm pre-setting device. As shown, control abutment 32 of a diaphragm pre-setting ring 30 is engaged by projection 23 of a spring urged depth of focus regulating member 15. A forward projection of the regulator 15 engages in slot 22 of a depth of focus indicating ring 8, which carries projections 7 slidable in grooves 6 of a sheath 3 secured to fixed ring 9, so that rotary movement of ring 30 is transmitted into axial movement of ring 8, the front edge of which co-operates with curved recess 4 and distance scale 2 on focusing ring 1 to indicate the limits of the depth of focus. The diaphragm actuating ring coupled to diaphragm blades 25 has a forked portion 24 (Fig. 2), engaged by arm 18 of a spring urged diaphragm regulator ring 14 which is normally held in a tensioned end position corresponding to maximum diaphragm aperture by retaining abutment 38 of operating ring 37. At shutter release, ring 37 is rotated by shutter mechanism (contained in the camera housing but not shown) to an end position so as to allow arm 18 of regulator 14 to engage projection 23 and thereby to set the diaphragm aperture to a value determined by the position of abutment 32 of ring 30. After exposure, regulator 14 is returned to its tensioned end position due to the return of ring 37 to its original position by the shutter mechanism. The objective assembly may be used with single-lens reflex cameras, and may be adapted as an interchangeable objective by providing connecting ring 9 with bayonet lugs 10 and by making the width of projection 23 in each interchangeable objective correspond to the relative aperture thereof. The diaphragm aperture setting ring 30 is releasably coupled with the shutter speed setting ring 35 by means of displaceable finger control 31, and blade spring 33 attached thereto and having a toothed portion 34 engageable with toothing in the ring 35. Ring 35 is also provided with a ratchet coupling 36, 29a with a fixed element 29 of the objective mount.
