Title: Improvements in and relating to calculating apparatus
IPC: G06G3/00
Filed: 1948-09-08
Abstract: 675,090. Calculating-apparatus. HARTLEY, N. O. Sept. 8, 1949 [Sept. 8, 1948], No. 23636/48. Class 106 (i). Calculating apparatus, particularly for use in statistical analysis, for solving equations of the form a<SP>2</SP>=b<SP>2</SP>+c<SP>2</SP>, comprises a base-member 1 carrying a scale 2, a slide 3<SP>1</SP> movable on the base in the direction of this scale and carrying a scale 4 at right-angles to the scale 2, and an arm 6 pivoted on the base at a point on the scale 2 and carrying a cursor 9. In one form of the apparatus, the scale 4 is fixed relative to the slide 3<SP>1</SP>, which is transparent, and when the latter has been set to the value b on the scale 2, the arm 6, which is also transparent, is pivoted until a line 8 on its under-surface intercepts the scale 4 at the value c. The cursor 9, which slides beneath the arm 6, is then moved to the intercept to enable the value of a<SP>2</SP> or a to be read from a scale 13 or 12, respectively. If a series of squares is to be summed, the cursor 9 is set on the intercept corresponding to the sum of the first two, the arm 6 is.swung against a stop 14 on the base 1 and the slide 3 is moved to bring the scale 4 into coincidence with the cursor line to enable the next amount to be added. The slide 3<SP>1</SP> is keyed to grooves 5 in the base 1 and frictionally held by a resilient member (not shown). To ensure perpendicularity, triangular members secured to the slide may also engage the grooves 5. To enable the sums of squares of deviations from an average x to be computed, the scale 4 may be slidable in the slide 3<SP>1</SP> so that the value x may be set against the scale 2. Such calculations may be started with the slide 3<SP>1</SP> at a definite distance along the scale 2, the latter being corrected according to this distance. To increase the range of the apparatus, several scales 4 may be marked on the slidable carrier in different colours and several interchangeable carriers may be provided. To evaluate a standard deviation where n<SP>1</SP> is either the number of observations or degrees of freedom, the summation is first performed so that the slide 3<SP>1</SP> is positioned according to the total and the arm 6 is then set, by one of several similar scales 19, at angle a to the base 1, where cot #=#n<SP>1</SP>. The value of s or s<SP>2</SP> may then be read from a scale 17 or 18, respectively, on the slide 3<SP>1</SP>. When analyzing a scatter diagram, the latter may be placed on the slide 31 and the dots used in turn in place of the calibrations on the scale 4. According to the Provisional Specification, a scale of squares may be added to the base 1 and standard deviations s are calculated by means of a square root scale on the slide and a cotangent scale (representing s) on the base. A scale of s<SP>2</SP> may also be provided. Moreover, the scales on the slide may be duplicated, one set being adjacent each edge so that the extreme ends of the scales on the base may be used.

Abstract: 691,303. Resilient mountings. NEIDHART, H. Sept. 21, 1949 [Sept. 23, 1948], No. 24270/49. Class 108 (iii). In a resilient support or buffer comprising relatively axially movable male and female members separated by non-adherent resilient bodies, the male and female members have respectively at least two axially separated sets of surfaces, each set comprising at least two surfaces of the male member disposed on opposite sides of the axis and opposed to correspondingly disposed surfaces of the female member to form two or more pairs of opposed surfaces of the male and female members respectively, the surfaces of the several sets being oblique to the axis and diverging from the axis towards the same end of the support, separate resilient bodies being disposed between the surfaces of the pairs of opposed surfaces in non-adherent rolling engagement therewith, so that relative axial movement of the male and female members under variation of axial load applied to them is permitted by elastic deformation of the resilient bodies as they are rolled between the surfaces of the pairs. In the arrangement according to Fig. 1, in which resilient rollers 3a and 3b are disposed between surfaces 2a, 2b and 4a, 4b of male and female members respectively, the male and female members are formed with stop portions 6 to limit the rolling of the rollers, and relative movement of the members under axial load. In another arrangement, Fig. 3 (not shown), two constituent parts of the female member which provide the surfaces 4a, 4b in the Fig. 1 arrangement are separate and may be held together by a common base-plate or on plates at the front and rear thereof. The female member may, however, be embraced by a tubular casing which includes a set-screw by which the rollers may be initially compressed. In a modification, Fig. 4 (not shown), the male member is of axially square crosssection and co-operates with four corresponding surfaces of a female member through four resilient rollers, the whole being embraced and held together by a tubular casing which may include means for adjustably pre-stressing the rollers. In the arrangement according to Fig. 5, the disposition of the surfaces of the male and female surfaces is such as to permit axial loading of the male member in either direction. In a modification, Fig. 6 (not shown), the surfaces of the members are modified to permit different spring characteristics in each direction of movement. In a further arrangement, Fig. 7 (not shown), in which the male and female members are similar to those of the Fig. 1 arrangement, an intermediate member is interposed between the male and female members resilient rollers being disposed on each side of the intermediate member between it and the male and female members. The arrangement reduces the height of the support for a given load and deflection.
