Title: Improvements in dumping waggons
IPC: B61D9/02
Filed: 1928-03-19
Abstract: 299,255. Krupp Akt.-Ges., r. Dec. 1, 1927, [Convention date]. Tip-wagons. - In a dumping-wagon of the kind in which the tipping action is effected either by a compressed air gear or by hand, the discharging gear is engaged by a stop which retains the body in its normal or travelling position but is positively actuated or displaced by a gear part common both to the compressed air gear and to the handoperated gear, so that locking or unlocking of the discharging gear takes place automatically. In the construction shown the body A of the wagon is tipped by a toggle mechanism b<3>, a<1>. which is secured in its lower dead-centre position by the engagement of a lug a<2> on the link a' with the stop g<3> carried by a sleeve G loosely mounted on a second sleeve E. which in turn is loosely mounted on the operating shaft b<2> but is capable of being coupled thereto by the engagement of a tooth f<1> on a sleeve F keyed to the shaft with an enlarged notch e' on the sleeve E, the arrangement allowing the tooth f<1> a certain amount of lost motion. On the sleeve E is a pinion D associated with a rack c<1> operated from the compressed air cylinder C, while on the sleeve G, which is actuated by a hand-lever H, is a double pawl J associated with a ratchet wheel b<5> on the link b<3>. A cam or projection e<2> on the sleeve E, Fig. 3. normally engages a seat or recess g<2> on the sleeve G, but is disengaged therefrom against the action of a spring K so as to effect a relative sliding movement between the sleeves E, G whenever, owing to the actuation of the compressed air or hand gear, a relative rotary movement occurs between the sleeves. Thus, when the compressed air gear is put into operation, the rack c<1> rotates the pinion D and sleeve E and, at the commencement of this rotation, the cam e displaces the sleeve G to the right, thus moving the stop g<3> out of the path of the lug a<2> and unlocking the toggle. As the sleeve E continues to rotate the tooth f<1> reaches the end of the notch e<1> so that the sleeve E and shaft b<2> are coupled and the toggle mechanism b<3>, a<1> is actuated for discharging. In restoring the body A to its normal position, the several steps are reversed and the toggle links re-locked. When the hand-lever H is employed it is first moved downwardly, causing the stop g<3> to be lowered or withdrawn and at the same time bringing an extension g<4> of the sleeve G into engagement with a fixed bracket b<6> on the underframe to prevent sliding of the sleeve G on the shaft b<2>. Simultaneously, the co-operation of the cam e<2> with the recess g<2> causes the sleeve E to slide to the left, breaking the coupling e<1>, f<1> and throwing the pinion D out of mesh with the rack c<1>. The pawl J is then engaged with the ratchet wheel b<5> and the lever H raised to rotate the shaft b<2> and effect the discharge movements of the body A In restoring the body again to its normal position the pawl J is swung over and the steps described are reversed.

Abstract: 749,296. Valve amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 25, 1954 [March 28, 1953], No. 8753/54. Class 40(6). Television signals including a D.C. component are separated by high- and low-pass filters whose outputs after being suitably amplified are fed to conjugate arms of a hybrid transformer, a third arm of which feeds the combined signals to a transmission line. After passing through a high frequency pre-emphasizing network 19 the signals are separated by low and high pass filters 10, 8. The high frequencies after amplification at 11 feed a push-pull class AB or B amplifier 12 whose output feeds the upper coil of the hybrid transformer 13. The low frequencies and D.C. are amplified at 15 and fed to the amplifier 16 connected between the centre point of the hybrid coil 18, 18<SP>1</SP> and earth. The transmission line 1 and the balancing network 14 form the other two arms of the hybrid network. By means of this arrangement neither of the high and low frequency components can enter the other's circuits to produce unwanted intermodulation products. Impedances 20, 21 which may respectively comprise inductance and capacitance may be added to the transformer network so as to build the circuit into a shunted T-filter matching the line impedance.

Title: Improvements in ophthalmic lenses
IPC: G02C7/02
Filed: 1926-04-01
Abstract: 262,319. Redfern, C. G., (American Optical Co.). April 1, 1926. Spectacle lenses are constructed with a first surface of such a curvature as to reduce to a minimum the marginal or oblique errors of focus and astigmatism when combined with a second surface to give the required power. A series of ophthalmic lenses is thus produced with oblique errors reduced to a permissible minimum. The method of selecting the first surface is described at length in the Specification, and involves "bending" " a lens of given power and plotting the sagittal and tangential errors of astigmatism in the form of a graph, Fig. 6, so that the curve giving no astigmatism is readily determined. As this curve usually results in an error of focus, greater than that permissible, a point 42 on the curves is selected giving an error of focus less than the point 39 of no astigmatism, but introducing a small amount of astigmatism. The amount of the errors allowed are in amount less than the difference in powers of successive first surface curves in the ordinary ophthalmic series of lenses. The lenses are supplied finished or as semi-finished blanks with appropriate charts of curvatures and central thicknesses. Examples are given in the Specification and Specification 165,834 is referred to.
