Filed: 1948-05-21
Abstract: 639,970. Vehicle wheels. PIRELLI SOC. PER AZIONI. May 21, 1948, No. 13878. Convention date, April 5, 1943. [Class 144 (i)] In a railway wheel of the kind comprising sets of resilient cushions 9, 9a fitted in compression between flanges 2, 3 on the wheel body and an intermediate flange 6 carrying the rim 7, and acting in shear under load, the cushions are fitted in metal pans 10, 11 recessed into the flanges, the lips of the pans being flared so that under increasing load the relative deformation of the cushion decreases.

Title: Improved means for regulating the speed of electrical machines
IPC: H02P7/26
Filed: 1921-05-20
Abstract: 167,744. Ges. f³r Drahtlose Telegraphie, and Schõffer, W. Aug. 9, 1920, [Convention date]. Motor-generators. - The speed of an electric motor M driving an alternating-current generator H is controlled by coupling to the alternating-current circuit a tuned circuit K in which the electric oscillations after being rectified and amplified act upon the controlling devices of the motor. In the arrangement shown in Fig. 1, the alternating-current motor M is controlled by magnetizing the cores T of inductances D by means of a coil S connected to the amplifying valve R. A second circuit in which the current is of constant frequency may be coupled to the circuit K and the latter tuned to the beat note produced. A continuous-current motor M, Fig. 4, may take the place of the alternating-current motor and may be controlled by connecting a field-magnet winding S to the amplifying valve R. According to the Specification as open to inspection under Sect. 91 (3) (a) the circuit K may be excited from a separate machine driven by the motor M, or directly from the motor M or alternator H, instead of from the external circuit of the alternator H.. This subject-matter does not appear in the Specification as accepted.

Patent GB-703017-A (GB)
Title: Cyclopentanoperhydrophenanthrene compound and therapeutic compositions containing it
IPC: C07J9/00
Filed: 1951-06-18
Abstract: A therapeutic composition m.p. 38-52 DEG C. is derived from ergosterol by oxidizing ergosterol dissolved in ethyl alcohol by passing gaseous oxygen through the solution at its refluxing temperature for 72 hours, diluting the reaction mixture with water, extracting the dilute solution with ether, extracting the ether extract with aqueous alkali, acidifying the aqueous extract to pH 6.5, extracting the acidified aqueous solution with ether, drying and evaporating the resulting ether extract to dryness and irradiating the resulting residue dissolved in ether with ultra-violet light.ALSO:A therapeutic preparation for parenteral administration consists of a sterile aqueous solution compatible with the bloodstream comprising a non-toxic aminogenic substance capable of releasing amino groups for amination under the conditions of administration, e.g. urea, and a much smaller amount of a therapeutic composition prepared by oxidizing ergosterol in solution in a saturated aliphatic alcohol containing not more than three carbon atoms with gaseous oxygen at refluxing temperature. In place of urea there may be used 1-arginine, 1-citrulline, 1-ornithine, glutamine and glycine.
Patent GB-177733-A (GB)
Title: Improvements in valves
IPC: F16K15/02
Filed: 1921-05-24
Abstract: 177,733. Sims, A. V. May 24, 1921. Check lift valves; rotating to ensure even wear.-A check lift valve 6, Fig. 2 is provided with a guard-plate 10 above and slightly spaced from the valve disc, with means for causing a slight rotation of the valve, and with fluid-passages of special shape through the seating to minimize resistance to flow. The valve disc 6 is of hard rubber and is preferably reinforced by a flat metal ring 7. Aflat plate 10 is pressed downwards by a spring 14 and is adapted to slide on the stem 8 until the boss 11, Figs. 2 and 3 enters a recess 15 in the hub 2. The plate 10 is then slightly spaced from the valve disc 6 in its closed position. Grooves 13 are cut on the underside of the guard-plate 10 so that when fluid is forced outwards from between the valve disc 6 and the guard-plate 10, a circumferential force is produced tending to rotate the disc 6. Liquid trapped in the recess 15 acts as a buffer to the disc 10. The ribs 3, Figs 2 and 4, of the seating are formed with warped surfaces which are generated by straight lines moving along a curved line 16 at the top and a straight line 17 at the bottom. Recesses 21 are formed at the top between the ribs, and the general construction of the passages facilitates the smooth passages of liquid. Recesses 22 are also provided for the insertion of a wrench when it is required to remove the valve seat. When the valve lifts, it is at first fluid-borne until fluid is pressed out of the interspace 12, after which the valve is lifted against the spring 14. Modifications are described in which the guard-plate is cushioned by a spring washer, and is adjustable on its guide collar to accommodate different thickness of valve disc, conical surfaces being provided to secure accurate centering. In the modification shown in Fig. 8, the stem 28 carries an adjustable collar 30 secured by a screw 31, and the plate 23 is arched at 33 so as to rest on the collar 30. When the plate 23 rises, fluid is trapped in the space at the top, and is expelled through the grooves 35 when the plate falls. When the lower ends of the grooves 35 are reached, fluid can only escape slowly through the clearance spaces, so that the plate 23 is cushioned.

Title: Microwave lines and high q filters
IPC: H01P1/203
Filed: 1956-05-11
Abstract: 809,482. Strip transmission line networks. STANDARD TELEPHONES & CABLES Ltd. May 11, 1956 [May 13, 1955], No. 14706/56. Class 40 (8). A strip transmission line for microwave frequencies comprises a ground-plane conductor 30 of approximately C-shaped cross-section and a round or ribbon-like line conductor 34 positioned between the in-turned ends of the ground-plane conductor. The line may be applied to the construction of filters, in which case two critically-spaced gaps 18, 19 in the conductor 34 are arranged to enclose a resonant section 35. The resonant portion of the line is supported either by a central dielectric block 39 or by posts 26 positioned at the extremities of the section 35 adjacent the gaps. The posts act as coupling loops and may also be placed at the ends of the sections 36, 37 on either side of the resonant section. The filter may be joined at either end to dielectric-filled strip transmission lines 41, 42 of known type, the necessary impedance transformation being provided by tapered portions 27 of dielectric beneath the conductor sections 36, 37. Since (in the construction shown) the dielectric in the filter section consists of air, the spacing between line and ground conductors is diminished and this may be achieved by the provision of conductive inserts 40 in the ground-plane conductor 30. Alternatively, the line conductor sections may be bent into closer proximity to the conductor 30. It is stated in the Specification that the main field of the propagated energy occurs in the gap d and that the width of this gap, for minimum loss, should be about 1/5 of the distance between the line conductor and the portion of the ground-plane conductor immediately beneath it. Propagation of spurious modes may be prevented by shortcircuiting posts 38. The centre frequency of the filter may be adjusted by controlling the slight amount of energy radiated by the gap d. To this end, the top of the filter section is enclosed in a metallic cover 43 carrying an adjustable screw 44. Specifications 709,351, [Group XL (c)], 761,761, 761,763 and 761,778 are referred to.
