Title: A continuously variable frictional change-speed gear
IPC: F16H15/52
Filed: 1962-01-26
Abstract: 949,922. Variable speed epicyclic gear. K. MAICHEN. Jan. 26, 1962 [Jan. 30, 1961; April 20, 1961], No. 3122/62. Heading F2D. A continuously variable friction epicyclic gear comprises an axially movable bevel sun wheel coacting with hydraulically supported conical elements slidable on pivots perpendicular to the gear axis under the influence of centrifugal force. An input shaft 4 is formed with a projecting ring 9 rotatably carrying radial pivots 10 to which are splined conical elements 11, urged radially inwards against centrifugal force by an hydraulic piston 21 to contact bevel sun wheels 14, 15. The sun wheels are braked for forward or reverse drive by disc brakes 29, 28 and have dog teeth 25, 26 engageable by teeth 24, 27 when the gear is in the direct drive condition. The inner ends of the pivots 10 are geared to an output shaft 5 through bevel gears 12, 13 ; the output shaft driving a sleeve 60 through a camming ball 36 and hydraulic cylinder 59 thrust augmentor to assist axial loading of the sun bevels. A pump 40 on the input shaft supplies pressure fluid from a tank 41 to actuate either brake 28 or 29 under the control of a forward/reverse valve 56, and also supplies fluid through a ratio change control valve 43 which pressurizes or exhausts the spaces behind the sun wheel and above the conical element pistons through internal ducting, the pressure being augmented according to torque by the device on the output shaft. In a modification, Fig. 3, the bevel gear 63 is fixed and drive from the input shaft 4, pivots 10, conical elements 11 and sun wheel 16 passes through gearing 66, 67 to a forward/ reverse bevel gear 71, 72, 73 driving a gear meshing with output gear 56 through a torque sensitive pressure device 80 to provide torque responsive speed control which may be manually overridden. Pump 40 delivers oil from a tank 86 (Fig. 6), to pipe 87, leading through relief valve 88 and one-way valve 89 to the sun chamber 17 and conical element pistons 21, and pipe 92 through one-way valve 91 to the torque sensitive device 80. When torque, and pressure in 80, is low, centrifugal force on the pistons 21 forces oil through pipe 95 and relief valve 93 to tank 86 allowing conical elements 11 to move outwards to the direct drive condition. On increase in output torque pressure from the device 80 loads the relief valve 93 causing the pistons 21 to move the elements 11 inwards towards a lower gear position. Manual control of the plunger 103 of the relief valve 93 provides for manual ratio change. In other modifications, the disc brakes may be cone or band brakes and a plastic or gaseous medium may be used instead of oil. The pivots 10 may be in a fixed housing, the shaft 5 being the driving shaft and the sun wheel 16 the driven element.
Patent GB-489580-A (GB)
Title: Improvements in or relating to fastening inserting machines
IPC: A43D69/04
Filed: 1937-02-03
Abstract: 489,580. Stapling. BRITISH UNITED SHOE MACHINERY CO., Ltd., LANE, H., and BRAY, W. N. Feb. 3, 1937, No. 3125. [Class 89 (iii)] Relates to stapling-machines of the kind in which the staples, during driving, are curved by engagement with an adjustable deflector so that they become anchored in the work, and consists in the provision of means for varying, at will, the length of the legs of staples formed from a continuous wire. Said means operate conjointly with the means for adjusting the deflector to vary the degree of curvature imparted to the staple. The invention is described as applied to the machine described in Specification 294,640, [Class 89 (iii)]. The deflector 5 is adjusted by an eccentric 3 which is adjustable on a shaft 1 rotatable by a hand lever 15. The shaft has a thread 9 engaged in a threaded bore in the slide 13 which carries the stapling mechanism, and a flange 19 engaging a slot 21 in a slide member 23. Thus, movement of the lever 15 to adjust the deflector acts also to move the member 23 laterally of the machine towards or from inside and outside formers 29, 31. The member 23 is formed with a stop face 26 up to which the staple wire is fed. A shearing plate 28 is carried by a slide 30 adapted to be moved, by toothed gearing, in conformity with the movements of the stop face 26, so that equality of the staple legs is maintained. The wire feed mechanism is adjusted to feed a staple length corresponding to the longest staple which may be driven, and one feed roll is' smooth to allow slip when shorter staples are being formed. The wire-guiding nozzle 51 is secured in a slide 53 which is biassed by a spring so as to follow the shearing plate in its movements. The shearing plate is adjustable on the slide 30 so that its shearing edge can be varied. The inside former 29 has a projection 62 which enters a slot in the deflector so that adjustment of the latter does not cause a gap between these parts. The driver 64 is a thin and somewhat flexible rectangular strip. The eccentric 3 is adjustable about the shaft 1. Specification 401,706 also is referred to.

The upper part or the cross-head a is hollowed at d<1> to receive the plunger or slide e' into which the screw is threaded.
Patent GB-791338-A (GB)
Title: Process and plant for continuous steam distillation
IPC: B01D3/38
Filed: 1955-02-03
Abstract: <PICT:0791338/III/1> A continuous process for the steam distillation of one or more components of a material comprises atomizing the material in a fine and regular form by means of superheated steam in which the material and the steam are introduced simultaneously through the same means into the atmosphere of steam under reduced pressure, thus assuring that all of the material comes in contact with the superheated steam.  The process is particularly applicable to the deodorization of oils and to the steam refining of oils and fats of low acidity.  A preferred plant for carrying out the invention comprises a supply tank 1 and a proportioning device 2 associated with a vacuum de-aerator 3 from which a pipe 7 leads to a heat exchanger 4.  A pipe 17 having a flow regulating device leads the material to a nozzle 19 which may cooperate with a heater 20 in a vacuum chamber 21 fitted with baffles 22.  Steam supplied from a superheater 29 is also fed to nozzle 19 and the steam and the material to be treated mixed. Chamber 21 is connected through pipe 43 to condensation units 44 fitted with a jacket 45 and pipe 55 leads to a condenser 56 fitted with a barometric column 57 which terminates in a tank 58.

Title: Method and apparatus for the titration of liquids
IPC: G01N31/16
Filed: 1950-02-08
Abstract: <PICT:0668237/III/1> <PICT:0668237/III/2> In the titration of a liquid with a liquid reagent in the presence of a coloured indicator, one of the liquids is caused to flow along a calibrated pipe made wholly or partially of a transparent material in order that the colour of the liquid can be observed and the other liquid is introduced to the pipe at several points along its length in quantities which are proportional per unit of time to that of the first liquid flowing along the pipe, the point in the pipe at which the indicator changes colour being read-off to define the titer of the liquid under test.  As shown, Fig. 1, the liquid to be titrated is drawn continuously under syphonic action through a transparent worm 5 from constant-level tank 3, an indicator also being continuously drawn into the worm through pipe 8 from tank 9.  The reagent is drawn into the uppermost points of the convolutions of the worm through pipes such as 11, 12, 13, the pipes being fed from a manifold 14 and constant head tank 15.  The points a, b, c, d of the worm correspond to a scale that enables the direct reading of the liquid titer to be effected.  Syphonic withdrawal is maintained by priming pipe 6. Fig. 2 shows a compact form of the worm 5, the straight portions being contiguous and the looped portions being alternately located in different vertical planes.  The method may be employed for the checking and control of water purification treatments, particularly the lime-soda treatment of boiler water, and two or more devices may be arranged in parallel, one for detecting the complete alkalinity, one for the apparent alkalinity and one for the chlorine content employing the usual indicators and reagents. The various worms may be adjacently mounted on a common panel provided with coloured captions corresponding to the colour changes of the indicator and indicating the adjustments to be made in the purification process.  The panel may incorporate, in addition, a pH indicating apparatus of the type described in Specification 668,236.
