Title: Differential gear mechanism
Filed: 1959-07-23
Abstract: 869,103. Differential gear; friction clutches. EATON MANUFACTURING CO. July 23, 1959 [Feb. 27, 1959], No. 25398/59. Class 80 (2). Differential gearing for motor cars is provided with a friction lock, tooth reaction of one of the gears when under load producing a lock-engaging thrust and a ring being associated with the lock to restrict the application of the thrust to the area adjacent the maximum diameter of the locking device. In one form, the usual crown wheel 30, Fig. 1, drives a bevel gear differential casing 10 supporting bevel planet pinions 35 meshing sun gears 32, 33, the latter being splined for limited axial movement upon its half-shaft 27 and coacting through a friction lock comprising a multi-disc clutch 13 with the differential casing. Under load, tooth reaction biases the sun gear 33 rightwards and compresses the clutch discs 13 between the back of the gear and a ring-shaped shim 58, Fig. 3, located at the radially outermost portion of a thrust surface 47 formed in the differential casing 10. Slip between the half-shafts 26, 27 when the road wheels of the car slip is thus prevented. In a modification, the shim 58 is replaced by a raised ring-shaped land 58, Fig. 5, formed in the casing 10. Alternatively, the shim &c. may be located at the back of the sun gear 39. The shim 58 or the equivalent land is arranged adjacent to a disc 54 of the clutch pack which rotates with the casing, or, if the shim &c. is at the back of the sun gear 33, the adjacent disc rotates with the sun gear. The clutch discs 54, Fig. 2, rotating with the differential casing 10, are formed with radially projecting lugs 59 which engage between the arms 61a, Fig. 4, of U-shaped hardened inserts 61 mounted in the casing. The clutch discs 55 rotating with the sun gear 39 are splined upon the hubs thereof. In a modification, Fig. 6 (not shown), slip-preventing locking clutches are mounted at the backs of both sun gears 32. 33, and the bevel planet pinions 35 are separated by a spacing bush surrounding their mounting pin 36. In another modification, Figs. 8 ... 11 (also not shown), the U-shaped hardened inserts 61 are replaced by two-part inserts.

Abstract: 725,781. Sausage skinning. GAINERS, Ltd. Sept. 15, 1953 [Oct. 28, 1952], No. 25437/53. Class 28 (2). Frozen sausages are peeled by hand pushing each sausage against peripherally arranged knives 16 at the right hand end of a tube 50 to make longitudinal cuts in the skin at least at the rounded end, softening the cellulose skin by steam admitted to the tube now containing the sausage and then peeling off or expelling the whole filling out of its skin by squeezing the uncut end between the fingers. The internal temperature of the sausage before treatment is approximately 10-15 ‹F. or not over 18 ‹F., and after treatment is 20-27‹F., or not over 28‹F. The knives 16 are pivotally mounted in slots 14 in the tubular knife holder so that they can yield away from the push of the sausage, the amount of yield being determined by adjustable tension springs 16 which determine the depth of cut. When the sausage enters the tube 50 softening steam is admitted through rows of slots 54 from an encasing cylinder 46 itself provided with a steam jacket 68. Condensed steam drips away through an orifice 96 and pipe 98.

Title: Method of sharpening the cutting faces of milling cutters with backed off o relieved teeth
IPC: B24B3/02
Filed: 1962-07-03
Abstract: 955,220. Sharpening milling cutters. F. HURTH, and H. HURTH. July 3, 1962 [Aug. 29, 1961], No. 25474/62. Heading B3D. A method of sharpening profiled milling cutters having backed-off or relieved teeth 10, Fig. 1a, consists in supporting each tooth, while it is being sharpened by a grinding wheel 14, at one or more points of the relieved face 17 of that tooth by one or more abutments 15 located at a selectable position in relation to the grinding plane 12, 13 and the axis 16 of the cutter. The single abutment 15 of Fig. la, supports the tooth 10 so that during sharpening a peripheral error on the tooth is corrected. The abutment is withdrawn to allow indexing of the cutter and then again advanced in the directions indicated by the arrows 18 or in directions which are inclined or perpendicular to these directions, the degree of advance being set by a stop. The abutment 28, Fig. 2a, is of U-shaped form and arranged so to embrace the relieved face of a tooth that, assuming the tooth to be laterally unwarped, rotation of the tooth until both of its flanks engages the sides of the abutment properly positions the tooth for sharpening. If the tooth should be laterally warped to one side, then, by rotating it until one flank engages the corresponding side of the abutment, the tooth is again accurately positioned for sharpening and correction of the lateral error. Instead of the abutment 28 being of U-shape a single abutment or two separate abutments may be employed.

Abstract: 626,870. Radio-navigation. O'BRIEN, W. J. Aug. 26, 1946, No. 25494. Convention date, Aug. 27, 1946. [Class 40 (vii)] A receiving apparatus for receiving two signals from spaced radio beacon transmitters and comparing them in phase comprises antennµ having different radiation characteristic patterns and means for successively receiving the signals on the different antennµ, whereby erroneous phase indications resulting from simultaneous reception of ground and sky wave-signals may be detected by comparing the determined phase relations of the signals from each antenna. - In a receiver for a navigation system such as is described in Specification 684,727 the receiver input may be connected by switch 7 either to a vertical . antenna 8 or to vertical loop antenna 12. The ground wave signals received by the open and loop antennµ will differ in phase by 90 degrees and if the received signals comprise ground waves, or include only sky-waves in phase with the ground waves, on changing over switch 7 the phase indication on meter 2 will change by a multiple of 90 degrees dependent on the factors by which the received signals are multiplied in receiver 1 before being phase compared. If, however, sky waves differing in phase from the ground waves are present these will add vectorially to the ground waves and owing to the difference between the vertical patterns of the two antennµ the phase shift on switching will in general differ from 90 degrees for each signal and differently for the signals of different frequencies, thus the phase change will differ from the correct multiple of 90 degrees so indicating the presence of sky-wave signals causing erroneous readings. Specifications 620,479 and 620,481 also are referred to.
