Title: Improvements in counting devices for railways
IPC: B61L1/16
Filed: 1922-06-01
Abstract: 188,619. Krupp Akt.-Ges., F. Jan. 12, 1922, [Convention date]. Indicating and recording movements of trains. -Railway vehicle wheels pass over a depressible treadle to close an electric circuit to the counting apparatus, the treadle being provided with a dash-pot to retard its descent and return to normal position and a locking device to prevent a damaged wheel or other cause from making incorrect circuit closures. Figs. 1 and 3 show sections of the treadle in different planes. A pivoted plate E is depressed by a passing wheel to move a bolt F against the action of a spring G. A disc f<2> attached to the bolt F and provided with openings f<3> moves in a dash-pot cylinder c<5> of liquid to retard the motion in both directions. During the descent of the plate E a finger e<3> tilts a pivoted bell-crank lever M against the action of a spring N and removes it from its locking position under a stop i<1> on a pins J, which is then depressed to close electric contacts K. When a wheel has passed over the treadle, the spring G restores the plate E to its normal position in a time determined by the dash-pot c<5>, and the pin J is raised when the power of a compressed spring H is lessened thereby below that of the spring (not shown) of the electric contacts K. If the pressure on the treadle be transitory, such as by dropping a heavy article thereon, or by a second depression of a damaged wheel, the action of the locking bell-crank lever M and the dash-pot c<5> prevents a second inaccurate closure of the circuit. The treadle may be adapted to operate a mechanical counter.

Title: Improvements in Hydropneumatic Suspension Systems for Vehicles
IPC: F16F9/24
Filed: 1967-04-04
Abstract: 1,169,999. Hydropneumatic suspension systems. SOC. ANON DE VEHICULES INDUSTRIELS ET D'EQUIPEMENTS MECANIQUES SAVIEM. 4 April, 1967 [27 April, 1966], No. 15475/67. Heading F2S. In a hydropneumatic suspension system in which a main vessel 8 rigid with a vehicle body 10 and having a piston 6, connected to a wheelcarrier arm 1 and working in a cylindrical portion 7 of the vessel 8, which portion 7 is connected, through a throttle valve 17, with an upper chamber with a diaphragm 12 which divides an upper gaseous spring compartment 13 from a lower hydraulic liquid compartment 11, an auxiliary gas spring vessel 14, having a pressure at normal load greater than that of the compartment 13, includes a resilient diaphragm 15 which, when the pressure in the auxiliary vessel 14, due, e.g. to high loading, is superior to that in the compartment 13, closes an orifice 16 connecting this vessel and compartment. When, during, e.g. long strokes of the piston 6, the pressure in the compartment 13 rises above that in the auxiliary vessel 14 the diaphragm 15 is lifted off the orifice 16 so that the effective volume of the gas spring is increased by the gas in the auxiliary vessel 14. In a modification, Fig. 3 (not shown), hydraulic fluid in the upper spherical compartment of the main vessel (8) has a pipe (19) leading therefrom to a separate auxiliary vessel (14) a diaphragm (15) co-operating with the hydraulic inlet to the vessel (14) and separating the auxiliary gas spring from the hydraulic fluid. A throttle (18) is also provided in the pipe (19). In a further modification, Fig. 4 (not shown), the pipe (19) leads from the cylindrical portion 7 of the main vessel (8) below the throttle valve 17.

Title: Apparatus for detecting pinholes in strip material
IPC: G01N21/894
Filed: 1972-04-05
Abstract: 1347645 Detecting flaws photo-electrically M J BINKS 5 April 1972 [13 April 1971] 15627/72 Heading G1A In an apparatus for detecting pinholes in moving steel sheet M irradiated from one side by a light source 32 and having a light detection arrangement including a plurality of light guides 90, an edge light shield 226 Fig. 5 is provided which includes an auxiliary photo-cell.sensing the light falling beyond the strip edge and providing an output to move the shield in and out to follow the strip edge and hence prevent light falling directly on the main light detection arrangement. Light from a number of A. C. -operated fluorescent tubes 62 is collimated by a honeycomb arrangement 68. The light guide arrangement 90, which may comprise a plurality of solid guides, Fig. 15 (not shown) or a honeycomb or louvre structure, Figs. 17, 18 (not shown), ensures that each point below the strip is responsive only to light coming from directly above. A plurality of light pipes 142 conveys light to a photo-tube 148. After amplification and filtering the output signal 168 may actuate a marking device to indicate the pinhole or, if the strip is discontinuous, may be operative to eject faulty individual sheets. In the absence of a sheet M from the apparatus the output from a low sensitivity photo-cell (172) Fig. 3 (not shown) actuates a shutter 170 which shields the photo-tube from high intensity radiation. The light shield 226 Fig. 5 includes a photocell 280 in a bridge circuit Fig. 21 (not shown). The bridge is initially balanced with the shield in the correct position relative the strip edge. Any subsequent out-of-balance current operates a relay to switch in a reversing D. C. motor (314). This motor drives the shield in and out to "follow" irregularities in the strip edge. The circuit is failsafe, in that if the light source fails or the light guides become covered by dirt, the motor moves the shield outwardly.

Title: Improvements relating to duplexer devices
IPC: H01J17/04
Filed: 1958-05-16
Abstract: 854,604. Waveguide switches. COMPAGNIE FRANCAISE THOMSON-HOUSTON. May 16, 1958 [May 17, 1957], No. 15856/58. Class 40(8). [Also in Group XL(a)] A duplexer device comprises a gas filled envelope together with means producing a magnetic field perpendicular to the required discharge path and of such magnitude as to induce cyclotron resonance at the operating frequency thereby initiating the discharge. The gas pressure is too low for the discharge to strike under normal conditions without the presence of a magnetic field, the low pressure enhancing diffusion and hence reducing the deionization time. In one embodiment a T-R or pre-T-R switch 1, Figs. 1, 2, comprises a waveguide section 2 one wavelength long and of H cross section. Glass or mica windows 3, 4 couple guide 2 to waveguides 5, 6 connecting the transmitter to a common aerial and providing the input for the receiver respectively. Guide 2 may be filled with hydrogen, and two magnetic polepieces N, S provide a constant magnetic field but which is slightly curved and extends along the transverse bar of the H. This ensures that cyclotron resonance can occur in at least one part of the envelope. A keep-alive electrode 10 in cavity 8 communicates with guide 2 through orifice 9. Flanges 14, 15 which fit into recesses 16, 17 enable guide 2 to be rotated thus altering the impedance presented to external guide 5. The voltage distribution along guide 2 is shown by curve U. An alternative construction comprises five waveguide sections 18-22, Fig. 4. Sections 18, 20, 22 have a low characteristic impedance and are nearly one half wavelength long. Sections 19, 21 have a high characteristic impedance and are about one quarter wavelength long. A standing wave voltage maximum occurs in the plane F-F<SP>1</SP> and this is where keepalive electrode 10 is situated. The polepieces of the magnet may be inserted into the body of the guide which is of non-magnetic material, and the magnetic field may be slightly inclined to the plane of the discharge electrodes as this shortens the diffusion path. A T-B switch 25, Fig. 7, is coupled by window 27 to guide 26 connecting the transmitter to an antenna. The device is ¥ of a wavelength long at the transmitter mid-frequency. A small quantity of radioactive material 31 provides the initial electrons for the discharges and the magnetic field is centred at this point.

Abstract: 958,241. Semi-conductor devices. TEXAS INSTRUMENTS Inc. May 6, 1960 [May 6, 1959], No. 16070/60. Heading H1K. A semi-conductor body, e.g. of germanium, silicon or intermetallic alloys is attached to an insulating, e.g. ceramic base by a cement, the thermal expansion coefficient of which matches those of the ceramic and semi-conductor. The wafer is then processed and a sealed enclosure, of which the substrate forms an external wall, formed around it. In one embodiment a semiconductor wafer in ohmic contact with metal strip or silver paste electrodes 3-6 (Fig. 1), on a ceramic base 1 is stuck to the base with a thermosetting cement, containing finely-divided glass, and is subsequently formed into a junction diode combined with a centre-tapped resistor, constituted by the semi-conductor wafer itself. A metal ring 11 (Fig. 2), coated with non-conductive glaze 12, or a ceramic ring metallized on its upper surface, is mounted on a low-melting glaze ring 13 applied over electrodes 3-7 and sealed thereto by heating to soften the glaze. Metal plate 14 is subsequently welded or soldered to ring 11 in inert gas or vacuo to form a sealed housing. A multivibrator formed from a single slab of semiconductor and of the circuit configuration shown in Fig. 4, is made by the following steps. A sheet of nickel-iron-cobalt alloy is etched to the form shown in Fig. 5 with indexing holes 53, 54. The sheet is positioned by these holes, a semi-conductor wafer ohisically soldered thereto in the position shown, and the assembly attached to a ceramic base as described above. The wafer is then subjected to various processes as described in Specification 945,734, to form therein the elements of the multivibrator circuit and to interconnect them. A housing is formed about the processed wafer broadly as described with reference to Fig. 2, but using a basically rectangular ring 52. The alloy sheet is finally cut along the dotted lines to isolate the various external connections of the circuit.
