Title: Level-controlled hydro-pneumatic suspension for vehicles
IPC: B60G17/04
Filed: 1968-10-07
Abstract: 1,205,148. Vehicle suspensions. V. LANGEN, [trading as LANGEN & CO.]. 7 Oct., 1968 [21 Dec., 1967], No. 47430/68. Heading B7D. A hydropneumatic vehicle suspension system incorporates level control as well as means to inactivate the suspension in a fully extended condition to give a substantially rigid connection between the vehicle body and wheels, and comprises hydraulic cylinder and piston suspension unit 20-23 interposed between the body and wheels, the piston chambers 16-19 of which are connected to the hydraulic pressure line 3, on the one hand, through controllable check valves 12-15 and level control valves 5, 6, 7 which connect the chambers to the line 3 or exhaust depending on the mean height of the body above the wheels and on the other hand, through non-return valves 50-53 opening towards the chambers, and a multiport valve 8, to which is also connected the control pressure line 44 of the controllable check valves, the annular chambers 32-35 of the units being connected to hydropneumatic accumulators 36-39 as well as to the lines 9, 10, 11 joining the controllable check valves to the level control valves, the multiport valve 8, in one position 1, pressurizing the control line 44 and connecting the lines 45-48 to the non-return valves to exhaust, and in the other position connecting the control line 44 to the exhaust while connecting lines 45-48 to the line 3. When the line 44 is pressurized, the valves 12-15 open so that bump and rebound cause cycling of the hydraulic liquid between the pistons and annular chambers, springing being provided by the gas springs in the accumulators 36-39, the level control valves, due to throttling elements 40-43 coming into effect only when changes occur in the vehicle loading. When line 44 is depressurized, i.e. in position 2 of valve 8, the check valves open only towards the piston chambers which are now connected to the line 3 through non-return valves 50-53 causing the suspension units to extend to their limit stops in which position the annular chambers of the units are connected to exhaust so that the full area of the piston is effective in supporting the load, and as the piston chambers are isolated because of the non-return and the controllable check valves a substantially rigid fully extended suspension is obtained which can support loads greater than those that can be supported at the maximum pump pressure.

Title: Manufacture of grid screen for x-ray photography sensitization
Inventor: KAMADA HATOHIKO
IPC: G21K4/00
Filed: 1971-10-12
Abstract: 1372526 Making grid screens FUJI PHOTO FILM CO Ltd 12 Oct 1971 [12 Oct 1970] 47551/71 Heading B3A [Also in Divisions C7 and H5] A method of making a grid screen for radiographic sensitization from a support provided with a first layer of material capable of being plated with a heavy metal and optionally of being etched and a second layer of a photosensitive polymer, comprises (1) exposing a grid image on the polymer, (2) developing the exposed polymer to uncover selectively the first layer and (3) either plating with a heavy metal or etching the etchable and plateable material, removing the remaining polymer and plating the remaining areas with heavy metal. The support is provided with a heavy metal layer on a film or thin plate of synthetic resin or paper. The synthetic resin may be coated with copper by electroless deposition followed by electrolytic deposition of additional copper or lead prior to coating with the heavy metal, which may be lead, copper, bismuth, thorium, silver or other metal having an atomic weight greater than 100. Alternatively the heavy metal layer may be formed on an epoxy or polyolefin resin adhesive on the support. The electroless deposition may be carried out by depositing metallic copper from an aqueous solution of the alkali-formalin type after etching, sensitizing and activating treatments. The heavy metal surface is coated with a light sensitive polymer, e.g. one consisting mainly of vinyl cinnamate, which is exposed to a negative grid image and developed to remove the heavy metal from the unexposed areas. These areas are etched to form the grid which is plated with additional heavy metal. Alternatively a thin metal layer is electroplated on the support and after a positive grid image has been exposed and the polymer developed, the exposed metal surface is further plated with a heavy metal. Finally the light sensitive polymer coating is removed and the thin metal layer etched away. The grid screen is coated with fluorescent material or is combined with a fluorescent sensitizing base. A thin layer of aluminium may be applied to increase the brightness of the screen.

Title: Electronic alarm timepiece
IPC: G04G13/02
Filed: 1976-11-16
Abstract: 1529278 Electronic alarm timepieces DAINI SEIKOSHA KK 16 Nov 1976 [22 Nov 1975] 47703/76 Heading G3T In an electronic alarm timepiece having actual time counters 4, 5 for minutes and hours respectively and first and second pre-set alarm time channels, the first comprising minutes and hours memory circuits 6, 7 and the second-minutes and hours memory circuits 8, 9, the contents of the first and second channel memories are periodically and sequentially sampled, e.g. during a 15m.sec period in each minute, and signalled to a coincidence circuit 14 for comparison with the contents of the actual time counters 4, 5. Upon each coincidence detection an audible alarm driver 13 is activated. For normal time display on a display device 12 e.g. liquid crystal or LED, a manual switch (not shown) controls a selector comprising a ring counter 20, 21, 22 so that stage 20 has a logic "1" output. Thus stages 21, 22 will have "O" outputs and consequently an output pulse from a NOR gate 23 opens transmission gates in a switching circuit 33 to pass signals from counters 4, 5 to decoder 10 for display on device 12. Likewise the outputs from stages 21, 22 are used to enable transmission gates in a circuit 26 to pass signals selectively to open the AND gates 27, 30 whereby the pre-set alarm times can be displayed. The 15m.sec. sampling control signal is derived by a NOR gate 26A which receives the minute pulses from a seconds counter 3 and a 32Hz signal from the fequency divider 2 and consequently produces 1 min. pulses of width 15m.secs. Thereby gates in the switching circuit 26, are controlled to pass a 128Hz signal from the divider 2 to the AND gates 27, 28 via an inverter and to AND gates 29, 30 directly, so that the contents of the alarm memories are successively signalled to the coincidence circuit. The sampling period is selected so that it is less than the response time of the liquid crystal display; or in the case of LED display-less than the response time of the eye, so as to eliminate flickering effect.

The bladder communicates with the valve inlet via sensing tube 38, passages in pilot valve 33 and tube 5, and upon pilot valve member 40 being shifted rightwards, by excess inlet pressure acting on diaphragm 39, the bladder is vented to passage 66 and moves to an open position 51a to allow gas to escape via nozzle 14, flame guard 13 and hinged check valve 25, flow through the nozzle tending to induce air-flow between dome 9 and cover 15, whereby the gas is diluted and escapes as a high velocity jet. If a vacuum developes at the inlet, the bladder is moved to an open position by atmospheric pressure thereabove. Upon releasing bolts 29 and nut 23, the cover can be pivoted about 18 to allow removal of the dome 9 for maintenance purposes. The pilot valve housing is held in position by detent 36 but may be rotated to expose parts for maintenance. Frangible disc 68 and flame guard 69 provide an alternative discharge path. In a modification a diaphragm anchored to a fixed plate co-operates with the main seat and carries a profiled nose extending through the seat. The diaphragm may be replaced by a piston. In each case the rim of the main valve member when in its open position lies in the plane of maximum crosssectional area of housing 2. The pilot valve bias is provided by an interchangeable unit 43-45 retained by circlip 45 beneath plug 46.
