Title: Improvements in the suspension of bodies of vehicles
IPC: B60G11/04
Filed: 1948-05-18
Abstract: 658,989. Vehicle suspensions. MOHL, S. May 18, 1948, No. 13417. [Class 108(ii)] In a motor vehicle having driving wheels carried by semi-elliptic leaf springs, the axle is connected to the leaf spring not at its centre but at such a position that when the driving torque varies, the consequential change in the horizontal force applied to the wheel circumference at its point of contact with the ground and in the vertical force between the spring and the wheel, combine to a resultant force which is directed to a point in the horizontal plane containing the centre of gravity, such point being on that side of the centre of gravity which is 'remote from the vehicle driving axle. The object is to minimize pitching and bouncing upon a change of driving torque. A formula is given for calculating the relative distances between the axle and each end of the spring in order to achieve the result. Fig. 1 represents a vehicle body A mounted on front and rear suspension Z 1 , Z 2 . The resultant force R occuring on a change of driving torque and referred to above, intersects the horizontal plane through the centre of gravity G at a point S on the far side of G. Fig. 4 shows an asymmetrically mounted axle 6 dividing the leaf spring 2 into unequal parts c, d, and Fig. 5 shows a wheel carried by a pivotal lever 9 and sprung by a spring 11, it being possible to so choose the effective length e of the lever 9 in relation to other constants of the vehicle as to achieve the same result.

Abstract: 495,339. Automatic tuning correction. GENERAL ELECTRIC CO., Ltd., and WELLS, G. M. May 13, 1937, No. 13554. [Class 40 (v)] The frequency discriminator network of an automatic tuning system comprises means for generating two voltages v1, v2 of equal frequency f2 but, whose phase relation alpha varies with departure of f2 from a frequency f1, the output of the discriminator being A + k #v1 v2 where A and k are contacts and #v1 v2 is the average of the product v1 v2 over one complete cycle. In Fig. 2 the coupled circuits 6, 7 ; 10, 9, are tuned to the same frequency (f2), their outputs being applied to a hexode 20 whose anode circuit comprises a resistance 23 across which a control voltage of the desired form A+k #v1 v2 is developed and applied to control frequency f1 to bring f1 and f2 into virtual equality. Frequency f1 is applied across the input 1, 2, and voltages v1 v2 are developed across points A, B and earth respectively. The hexode 20 is so chosen that its average anode current is of the form I=I0+k V1 V2 cos alpha, where V1, V2 are the peak values of v1 and v2. The control voltage may be applied either to vary the bias of a control valve or to a mechanical device such as an electrodynamometer; in the latter case the voltages v1 v2 are applied to a pair of valves in each anode circuit of which is arranged a dynamometer coil. The mechanical resultant is then, according to the Specification, of a form corresponding to A + k #v1 v2. Specifications 332,834, [Class 40 (v)], and 392,567 are referred to.

Abstract: 896,968. Ammunition fuzes. JUNGHANS A.G. GEB., and JUNGHANS, H. April 24, 1959 [April 25, 1958], No. 14122/59. Class 9(1). A fuze for spin-stabilized projectiles comprising self-destruction means has a body 10 in which are pivoted levers 18 supporting a sleeve 21 and so stressing a spring 20 surrounding the hammer 12 for a firing pin 13. Projections 18d bearing against an apertured plate 16 resting on a spirally wound safety element 14 hold the levers in the supporting position. The element 14 carrying the plate 16 surrounds a core 15 through which the pin 13 extends, a collar 13a of the pin being received in a recess in a flange 15a of the core, which flange secures the plate 16. The levers 18 are guided in slots, Fig. 2, of a plate 19 mounted on the upper edge of the body 10. Before firing the projectile fitted with the fuze, the centres of gravity of the levers are above their pivot axes and on discharge the levers move forward due to centrifugal force, slightly lifting the sleeve 21. The element 14 moves due to centrifugal force and frees the disc 16. As the rotational speed decreases, the levers move to a position S 2  in which an impact blow on the hammer 12 would be transmitted through the levers to the core 15 and firing pin 13 to fire an ignition pellet (not shown) inserted in a recess 10a. Should impact not occur at this stage, as the rotational velocity decreases further the spring 20 drives the levers 18 through the sleeve 21 to force the firing pin against the pellet. Instead of mounting the levers on pivot pins, they may be provided with rounded ends resting freely on bearing surfaces in the body 10. Two levers may be used instead of three, Fig. 4, and the hammer 50 may be rigid with the firing pin 51. The levers bear directly on the element 14 and the core 15 is replaced by a sleeve 53, which is slotted to receive a semi-circular disc 52 supporting a collar 51a on the firing pin. The disc 52 escapes from the sleeve after the element 14 unwinds and so releases the pin 51.
