Title: Improvements relating to vehicles with double axles
Inventor: STUMP EUGEN
IPC: B60G5/00
Filed: 1962-02-15
Abstract: 940,406. Steering vehicles; absorbing lateral shocks. DAIMLER-BENZ A.G. Feb. 15, 1962, No. 5927/62. Headings B7D, and B7H. A vehicle comprises a double axle arrangement wherein the two axles 10, 11 are guided in opposite directions by a lever 27 pivoted to the vehicle frame at its approximate centre and articulated at the ends of each of two of its arms to a pair of generally longitudinal guide members 14, 14<SP>1</SP> and 21, 21<SP>1</SP> attached to the respective axles. Positive steering may be provided by connecting a further arm 28 on lever 27 to the vehicle steering gear through rod 29. The vehicle is supported by the axles 10, 11 through preferably pneumatic springs 20 mounted on transverse members 19 secured to the guide members. The axles are located transversely of the vehicle either by Panhard rods 30, 31 when positive steering is provided (Fig. 2) or by transverse rods mounted between the frame and the two transverse members 19 (Fig. 3). The axles may be stabilized in the central position by a device 32 which also absorbs lateral shocks mounted between the frame and guide member 14<SP>1</SP> (Fig. 3), lever 27 or one of the axles. In Fig. 3 the device 32 comprises a stepped cylinder 33 connected to the frame containing a preloaded spring 34 between plates 35, 35<SP>1</SP> and a rod 37 connected to guide member 14<SP>1</SP> and having a pair of discs 38, 38<SP>1</SP> bearing against the plates 35, 35<SP>1</SP> in the central position. When the load in rod 37 exceeds the spring preload, as when cornering, disc 38 (or 38<SP>1</SP>) moves plate 35 (or 35<SP>1</SP>) further compressing the spring. The axle may be fixed in the central position by applying air pressure through inlet 47 between pistons 41 and 42 when flanged end 48 of member 45 connected to the axle is clamped between flange 43 and disc 44 of the pistons 41 and 42. In a modification hydraulic fluid is supplied between the plates 35, 35<SP>1</SP>, which are in the form of pistons, from a differential area piston the other side of which is subject to air pressure (see Fig. 4, not shown). In an alternative arrangement (Fig. 1, not shown) the guide members of the rear axle form a single central member between the lever 27 and transverse member 19 from which they diverge to the axle.

Title: Improvements in thermionic valve circuits
IPC: H04B15/06
Filed: 1923-03-02
Abstract: 216,589. Willans, P. W. March 2, 1923. Thermionic amplifiers and detectors; heterodyne receiving systems.-The oscillations set up by a back-coupled valve are prevented from energizing an aerial or other input circuit by a bridge arrangement of the circuits. As shown in Fig. 1, the plate circuit of the valve V is back-coupled to a tuned grid circuit B. One side of this circuit i connected to the grid of the valve and the other side is connected to the filament through an impedance X equivalent to the grid-filament impedance of the valve. The aerial coil A is connected between the filament and the mid-point of the grid coil B, which are points of equal potential as regards oscillations in the circuit B, which therefore do not affect the aerial coil A. The coil A may be connected to a point between two condensers instead of a mid-point of the coil. In a modification shown in Fig. 2, the aerial A is coupled to a coil C, which is connected at one end to the grid of the receiving-valve V, at its midpoint to the filament through a tuned circuit F, B, and at its opposite end to a balancing impedance X shown as an unlit valve similar to the valve V. The plates of the valves are connected to each other and the plate coil E is back-coupled to the tuned grid circuit F, B. An electrostatic shield D separates the aerial coil A from the coil C. A resistance Q may bel provided across the grid and filament of the unlit valve X, if the receiving valve passes grid current.

Filed: 1917-05-01
Abstract: 106,098. Lawrence, L. C. May 1, 1916, [Convention date]. Limbs, artificial.-An artificial limb is composed of sections pivotally jointed together, each section being built up of a number of shaped plates adjustably secured to each other for lateral adjustment. A leg member comprises a thigh portion built up of four plates 73, 74, 75, 76, Fig. 3, with slots for connection with a knee section 56, 57, 59 similarly built up. The knee joint has side plates 54, 55 carrying a pivot pin 52 and a screw 58 for enlarging the joint. The leg section is similarly built up of plates 32, 33, 34, 35 and is provided with a recessed upper end to engage the side plates 54, 55. A spring 26 is provided in the ankle section to bear on the foot 10, a resilient block 79 acts as a buffer, and tension cords 27 are employed for connecting the back plate of the ankle section with the foot and the back and front plates of the ankle section. The ankle pivot-pin 15 passes through an eye-bolt 16 secured to the foot, and freely through one of the depending knuckles 14 formed on the side members of the four plates constituting the joint, but has threaded engagement with the other. By this means the side plates may be drawn together, or they may be forced out by means of a screw 24 above the pin. The form characterizing the adjustable-plate construction of all sections is shown in Fig. 1, wherein the ankle section is adjustably secured to a leg section comprising side plates 32, 33 and front and rear plates 34, 35, Fig. 3, by screws 37 passing through slots 36, 38 in the ankle and leg sections respectively, permanency being maintained by other screws 40 in threaded holes 39, 41. Control of the knee joint is maintained by means of a tension cord 63 at the extreme back of the joint and also by a compression spring 69 which is acted upon by an arm 66 tending to force the spring into its containing tube 71 as the joint straightens, the lower end of this tube abutting on a cup-shaped support. The thigh sections have padding 77, 78 to receive the stump, and a limb may be constructed without knee-joint, having a calf socket.

Abstract: 512,455. Photographic copying apparatus. KODAK, Ltd. March 4. 1938, No. 6907. Convention date, March 5, 1937. [Class 98 (i)] A copy-holder particularly adapted for supporting a book for photographic copying comprises a frame 13, supported by rollers 14 on a base 10, and having mounted thereon a pair of supports 15, 16. to which the covers of the book 34 are secured, so that an open page of the book is located below a camera 12. The supports 15, 16 are carried by pairs of parallel links 19, 20, so as to remain always in the horizontal position and are balanced by springs .23. One cover of the book is clamped to the support 15, and the other to a tensioning-member 24, which is mounted to slide on the support 16, and is drawn outwards by springs. so as to tension the bookcovers. An auxiliary support for the back of the book comprises a rod 41, mounted at its ends on screwed spindles 42. which are supported in posts 43. The rod 41 can be raised, so as to engage the back of the book. by nuts engaging the spindles 42 and rotated by gearing from a handle 69. The rod can also be adjusted transversely by means of screw-mechanism, so as to position it opposite to the junction 38 between the open pages of the book, and to cause it to follow the junction as it moves consequently upon the turning of the pages. By the action of the tensioning-member 24 and the backsupport 41, the open pages are maintained flat and in the same plane. The frame 13 is moved on the base 10 to bring the right- and left-hand pages of the book alternately beneath the camera, and its movement is limited by adjustable stops, or, alternatively, the frame may be reciprocated by a motor 73, which is connected to it by a slotted arm 74 and a link 75.
