Title: Improvements in or relating to roller bearings
IPC: F16C23/08
Filed: 1949-06-08
Abstract: 665,499. Bearings. AKTIEBOLAGET SVENSKA KULLAGER-FABRIKEN. June 8, 1949 [July 21, 1948], No. 15316/49. Class 12 (i). To minimize the stresses of a roller bearing at optimum loads, the radius of curvature r2 of the outer race-ring 1 is greater than that, r<SP>1</SP>, of the rollers 3, 4 and less than that, r<SP>3</SP>, of the inner race-ring 2. This provides that the contact areas between the rollers and each raceway is elliptical, the major axis of each ellipse being equal in length though the minor axes differ, and that while the major axis is contained within the roller length l on light loads, it extends beyond this length on optimum loads to give a substantially rectangular contact area at each raceway. Loads in excess of this optimum considerably widen the contact area at the roller ends. The Specification refers to suitable proportions of such a bearing and to its contact areas evaluated by a theory of Hertz.

Title: Improvements in or relating to computers

Filed: 1960-05-05
Abstract: 935,019. Digital electrical calculating apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 5, 1960 [May 8, 1959], No. 15945/60. Class 106 (1). A check is made as to whether code representations of the result of an arithmetical operation are significant or not and in the latter case if a single error has occurred the error is corrected. Fig. 5 shows a basic binary adder in respect of the third denomination in which the accumulator comprises a trigger pair 3 and the number y to be added is entered into trigger pair 13. The Figure is self-explanatory except in that a value v 3  is calculated. If the digit in the sum trigger pair 3 is to be changed v 3 =1 and coincidence with a clock pulse k opens AND gate 53 to change over 3. If v 3 =0 no change-over takes place. Fig. 7 shows a string of adders for eight digit places, the accumulator comprising trigger pairs 0-7 and the y input being entered into trigger pairs 10-17. The v outputs are fed in the combinations shown schematically in Fig. 8 to logical circuits 62-65. According to whether the number of v inputs in odd or even so circuits 62-65 feed an output of 1 or 0 to corresponding AND gates and so to check trigger pairs a, b, c, d corresponding to the trigger pairs 0-7 which receive the individual v outputs through AND gates 50-57 from the corresponding basic adders. Trigger pairs 0-7 and a-d further influence logic circuits 66-69 which feed correcting circuit 70. If a single error has occurred then circuit 70 inhibits gate 72 to stop the next clock pulse. At the same time any discrepancy between the outputs of one of the logical circuits 66-69 and the combination of the inputs to the corresponding circuit 62-65 and its output is revealed in checking circuit 70. Circuit 70 therefore applies a correcting pulse to the indicated trigger pair 0-7, a-d, and simultaneously sets up an alarm. In the event of continued failure of an AND gate 50-61, the adder continues to function correctly but at reduced speed. A ternary adder is also described in which case the correction circuit operates in a broadly similar manner with a base of 3.
