Title: Improvements in pistons for the working cylinders of internal combustion engines
IPC: F16J1/18
Filed: 1919-01-15
Abstract: 166,200. Hawkes, C. J., and Newman, A. W. Jan. 15, 1919. Pistons; pistons, balancing laterally and reducing and equalizing wear of; connecting-rods.- In an aluminum or other piston of an internalcombustion engine the gudgeon-pin is carried by a steel, manganese, bronze, or other hard-metal block or blocks. The skirt a<1> is separate from the head a and is recessed to receive hard-metal blocks b carrying the gudgeon pin c. Studs d securing the skirt a<1> to the head a pass though the blocks b and through the gudgeon-pin. In a modification, the blocks bare let into recesses in the head a. Alternatively, a hard-metal belt carrying the gudgeon-pin may be interposed between the head and the skirt of the piston. The studs securing the skirt to the head pass through the belt and through the gudgeon-pin. The belt may be of less diameter than the skirt and may be provided with wearing pieces of antifriction metal. The gudgeon-pin may alternatively be carried by the connecting- rod and work in bushes in the hard-metal blocks, which may be in halves in order to facilitate insertion of the bushes.

Title: Improvements in or relating to television
IPC: H04N7/08
Filed: 1950-01-19
Abstract: 675,887. Television. PYE, Ltd., and WEIGHTON, D. Jan. 19, 1951 [Jan. 19, 1950], No. 1472/50. Class 40 (iii). [Also in Group XL (c)] Two separate radio television channels, using synchronized line and frame-scanning frequencies, are accommodated within a frequency band only slightly wider than that normally occupied by one vestigial sideband transmission, and the pictures are separable by a receiver so that they may provide an alternative programme, or may carry complementary components in a stereoscopic or colour system. In the system illustrated in the frequency diagram, one picture is sent on a carrier frequency c2 in the form of a complete lower sideband, and a vestigial upper sideband a, and the other on a carrier c1 with a complete upper sideband b and a vestigial lower sideband. The curves A and B represent the transmission characteristics of the two filters used in the receiver for directing the two channels to their respective detectors. The A detector yields the television signal of the channel a together with interfering signals produced by the b picture signal bearing with the carrier c2. In order to prevent interference patterns from becoming visible on the television screens, the separation between the carrier frequencies of the two channels is made equal to a high odd multiple of half the line scan frequency, or to that value plus or minus one half the frame scan frequency. The Specification states that under these conditions consecutive lines, or consecutive frames, of the interference picture are in phase opposition and annul each other. The separation of the two channels may be facilitated by employing differently polarized waves for the two transmissions. In a modified system, the two carrier frequencies are comparatively adjacent, being separated by a small odd multiple of half the line frequency plus half the frame frequency. They are radiated from two aerials arranged to produce respectively vertically and horizontally polarized waves, the receiving aerials being arranged to be responsive to the polarization of the respective transmissions. Either the upper or the lower sideband is used, the same sideband for both transmissions. In all modifications the line and frame scanning frequencies of the two transmissions are synchronized.

Abstract: 894,354. Friction clutches. VAN DOORNE, H. J. Jan. 19, 1960 [Jan. 21, 1959], No. 1973/60. Class 80 (2). A centrifugal friction clutch comprises pairs of shoes 4, 5 with common pivots 3 and subjected to control springs 6, 7 of different loadings in order that the individual shoes may become operative at different speeds, each leading shoe 4 being self-energizing while the trailing shoe is not, the springs 6, 7 being so arranged that shoe 4 becomes effective at a higher speed than shoe 5. In the construction according to Fig. 3, the control spring 13 of each trailing shoe 5 is connected to an arm 10 movable between stops 11, 12, so that as the speed increases the centrifugal effect of arm 10 reduces the effectiveness of shoe 5. A similar effect may be obtained by fitting a counterweight to the shoe 5, Fig. 5 (not shown). By this means the leading shoe 4 has a continuously rising torque-speed characteristic, while that of trailing shoe 5 may rise non-uniformly, or rise to a maximum and then fall.

Abstract: 1,213,511. Testing coins. AUTELCA A.G. 16 Jan., 1968 [20 Jan., 1967], No. 2416/68. Heading G4V. In a coin testing device for use with a vending machine or automatic telephone system, coins pass down a shoot through the field of an induction coil in the tuned circuit of an oscillator and the output of the oscillator rectified and applied to a gating circuit controlling a deflector at the outlet end of the shoot to divert the coins to an acceptance or rejection channel. The oscillator is tuned so that only unacceptable coin cause the oscillations to cease as they pass through the field of the induction coil. Thus, the rectifier emits an output pulse when an unacceptable coin is detected which is applied through a univibrator to control an INHIBIT gate. A second signal generated by a microswitch or a second induction coil as any coin passes down the shoot is applied directly to the input of the INHIBIT gate. The deflector comprises a pivoted finger or a flat plate pivotable about opposite edges.

Abstract: 823,502. Ventilating closed spaces. GARRETT CORPORATION. Jan. 24, 1958 [Jan. 25, 1957], No 2461/58. Class 137 [Also in Group XXVIII] Air conditioning apparatus for cooling and oxygenating the air in a closed space comprises a container for liquid oxygen, a heat exchanger in which heat is transferred from the air to the oxygen to cool the air and vaporize the oxygen, means for adding the vaporized oxygen to the air and means employing the energy of the vaporized oxygen to withdraw the air from the closed space, circulate it through the heat exchanger and return it to the closed space. As shown, liquid oxygen contained in insulated vessel 30 is led by pipe 32 to the annular space between vortex tube 13 and outer jacket 34 of the heat exchanger. Within this space is a helical baffle 36 sealed at the top to plate 40 so that vaporized oxygen can only escape via valve 23 which is controlled in response to conditions of temperature pressure, and oxygen availability in space 10 by sensing element 24. The oxygen flows into pipe 22 and thence it is injected from nozzle 20 tangentially into vortex tube 13 with a slight downward component. This causes a withdrawal of air from space 10 through pipe 11 and circulation through vortex tube 13 and pipe 16 back to space 10. In passing through the vortex tube, oxygen and air mix and reach a combined temperature, some heat being given up to tube 13 and transferred to the liquid oxygen causing further vaporization. A pressure release valve 31 releases any excess oxygen pressure evolved as a result of vaporization in vessel 30 into tube 22. In an alternative embodiment, (Fig. 3, not shown) the vortex tube is situated within the container for liquid oxygen, heat exchange taking place directly between the outer surface of the vortex tube and the oxygen.
