Filed: 1925-10-08
Abstract: 241,884. Petzholdt Maschinen-Fabrik, J. S. Oct. 22, 1924, [Convention date]. Mills and apparatus. - In apparatus for finely disintegrating and rubbing down preliminary disintegrated cocoa beans, cocoa, chocolate, and the like in which the particles of the material have a rapid revolving motion imparted to them by beaters which co-operate with retarding means such as retaining and rubbing surfaces, the rapidly-rotating beaters co-operate with retaining and rubbing surfaces in the form of annular chambers or passages embracing the beaters, against which the material is forced by the beaters and along which it is driven, the chambers or passages preventing the material from moving out of the path of the beaters. Fig. 1 shows a section of a multi-stage apparatus comprising a cylindrical casing a containing discshaped partitions o between which beating arms or crosses c, carried by a rapidly-rotating shaft b, work. The partitions o are provided on both sides with rubbing surfaces p, and similar surfaces are provided on the cylinder wall between the partitions and on the insides of the end walls e, f. The lateral surfaces of the beater heads d converge in the. direction of rotation and the end surfaces are inclined upwards opposite to the direction of rotation as shown in Figs. 2 and 3. A feed-hopper i is provided on the end wall e, and a discharge shoot k on the end wall f. The axial outlet opening h in the wall f has a radial downward extension h<1> regulatable by an adjustable slide m. The material is forced against the surfaces p surrounding and embracing the beater heads d to both sides and towards the outside against the casing wall by the rubbing action of the heads d. The beaters may be constructed so as to have an axial conveying action, or be provided with axial conveying means. The cylindrical casing may be widened in steps or conicallv from the inlet to the outlet, the diameters of the beaters increasing correspondingly. Or cylindrical and conical or stepped casing parts may succeed each other. The apparatus may be made with a vertical axis, the material being fed in at the top when the casing is cylindrical or when it increases in diameter towards the bottom, and at the bottom when the diameter increases from the bottom to the top. A roughing-mill of known kind with the revolving grinding-disc fixed on the beater-shaft is placed in front of the first beater stage when cocoa beans are to be treated in the apparatus.

The signals at points 12, 21 in the loop are compared in phase comparator 19 to produce a control signal for a variable phase shifter 17 in the loop. A further phase comparison may also be made in comparator 37 to control further phase shifters 43 1 , 43 2 , the signal to this comparator from point 12 being delayed by delay 41 before being applied to it. Alternatively, Fig. 3 (not shown), the signals to the second comparator may be derived from lines 10, 15. Instead of continuously variable phase shifters fixed phase shifts may be switched into the loop by control signals derived from the comparator by logic circuits, Fig. 4 (not shown). The arrangement is used for lengthening the signal bursts used to lock the oscillator 65 in a radar counter measure installation, Fig. 5. Short burst of signals are lengthened in recirculating loop 61. In a first operating mode switch 62a, is closed, switch 68a connects channel 68 to circuit 57 and oscillator 65 has its frequency set to that of the received signal by the control signal derived from phase comparator 63. During a second mode, switch 62a is open and switch 68a connects oscillator 65 to circuit 57, the oscillator is then controlled by the signal circulating in this loop by the signal derived from phase comparator 73.

Filed: 1935-09-12
Abstract: 462,336. Gauging alignment of connecting-rods. THOMPSON, J. W. Sept. 12, 1935, No. 25316. [Class 106 (ii)] Relates to apparatus of the kind comprising a shaft mounting for one end of the rod and a direct - reading indicator adapted to be operated by a two-point contact with the other end bearing or gudgeon pin, and consists in adjustably mounting the indicating mechanism in guides on the frame 1 of the device and adapting the mechanism to be turned through an angle of 90‹ or more, about an axis at rightangles to the pointer pivot. A frame 1 is provided at the lower part with a split bearing 2 to receive a mandrel 3 which is clamped by a screw 4. The forward end of the mandrel is provided with taper keys 6 engaging guideways in the shaft 3 and which may be expanded simultaneously outwardly by rotation of a disc 8 on a screwed rod 9 a detachable cap being provided with a pin to engage a slot in the end of the rod and so rotate it. The frame 1 has a vertical slot or guide 13 for an indicator plate 14 on which is pivotally mounted a pointer 15 normally at right angles to the axis of the mandrel 3 and reading zero. In use, the big end is placed on the mandrel 3 which is expanded out to fit it. An indicator operating member 16 pivoted at 16x is bifurcated to afford two spaced contacts lying in a line normally parallel to the axis of the shaft 3 and in the path of the gudgeon pin when the rod is rocked about the mandrel. The member 16 has a pin 15<y> which engages a notch in the end of the short arm of the indicating pointer. When the rod is moved so that the bifurcations engage the gudgeon pin, if the ends of the rod are not in alignment, the member 16 is rocked and the pointer 15 moved to one side or other of zero on the scale 14. The plate 14 may slide on ball bearings 17 and be moved into engagement with the gudgeon pin when the rod is held vertically with the same result. The plate is carried by a bracket 18 carried by a horizontal stud 19 working in the slot 13 and associated with a cam or lever whereby the bracket may be clamped in any position of angular adjustment about the axis of the stud. The plate 14 may be turned through say an angle of 90‹ and a test made with the plate in a vertical position. An L-shaped member 21 slidably mounted in a bearing 22 adjacent the mandrel 3 is adapted to be locked in any position by a set screw 23. The indicator mechanism may be moved to the top of the guide and the rod placed on the mandrel and swung over until the small end is opposite the machined face 13<x> whereupon, the member 21 is set with its outer arm touching the big end near the mandrel. The distance of the small end from the machine face is then measured with a rule and the rod reversed with the small end on the mandrel and the test repeated. Any difference in the measurements means that the rod is bent or cracked.

[Class 135] Apparatus for adjusting the blades of a propeller whilst turning comprises a fluid-pressure servomotor which rotates with the propeller shaft and is enclosed in a stationary casing sealed where the propeller shaft passes through it. In an embodiment, the servomotor comprises twin pistons 46, 47 working in a cylinder interposed in the propeller shaft 2. When the pitch of the propeller blades is to be adjusted, a signal is transmitted through a hydraulic circuit at 12 to move a piston 11 against its spring loading 68. This movement is transmitted to a slide 66 and then through a floating lever 67 to a piston valve 10 which controls the flow and exhaust of pressure fluid through lines 17, 18, grooves 19, 20, and passages 63, 64, to and from the servo-cylinder. The subsequent movement of the servo-piston moves rod 48 to alter the pitch of the propeller blades and also moves a disc 74 along the shaft 2, the disc being provided with a groove in which the other end of the floating lever is housed so that the control valve 10 will be recentred to the neutral position shown. The pistons may be replaced by rotary elements of the helical vane type. The control valve casing is formed in two sections 4, 5 constituting a bearing for the rotating servo-cylinder. The stationary casing is supported from a rigid framing by springs of which there may be one or more on each side, and abutments limit the rolling action of the casing. A pump carried inside the stationary casing and driven from shaft 2 draws oil from a sump formed in the casing and delivers it to an external reservoir. The propeller shaft where it passes through one end of the casing is provided with lubricating holes by which oil is led to the space between the propeller shaft and shaft 48. Oil leaking past the stuffing box is led back into the stationary casing.
