Title: Fluid-operated valve assembly
IPC: F15B13/043
Filed: 1964-08-07
Abstract: 1,057,768. Valves. PARKER-HANNIFIN CORPORATION. Aug. 7, 1964 [Aug. 7, 1963], No. 32271/64. Heading F2V. Two pilot-actuated main-valves 56 which control the operation of a double-acting motor are disposed in a housing made up of a reinforced, partitioned and cored die-cast distributing- block 2 which has a cover 3 that supports a solenoid-operated pilot-valve block 4; the block 2 and cover 3 accommodate a plug 40 and socket 41 whereby electric current is taken to 'the solenoid 43. The valves 56 are each formed as a cartridge 36, the latter being joined by a plate 53 which angularly locates them in the block 2 and facilitates their removal. Each valve 56 co-operates with seats 57, 58 and incorporates a depending guide and an upstanding piston 60 in a chamber 71. With the solenoid de-energized a spring 67 urges the armature 68 on to a seat 69, so opening a seat 48 and enabling fluid from an inlet chamber 15 to chamber 71 via a check valve 31, a chamber 32 and passages 46, 47, 66 and 65, whereupon the pistons 60 are lowered to close valves 56 upon seats 57. Fluid from chamber 15 is thereby permitted to traverse a passage 17 and right-hand seat 58 to a motor chamber 24; the motor exhaust fluid enters a chamber 23 and flows to an exhaust chamber 20 via lefthand seat 58 and a passage 22. The motor is moved in the opposite direction upon energizing the solenoid 43 to close seat 48 and open seat 69. The check valve 31 traps sufficient fluid in chamber 32 for one downward actuation of the valves in the event of a loss of pressure in chamber 15. Each valve 56 may have its own pilot valve. In a modification, the pilot valve directly controls the right-hand valve 56 only, the latter in turn controlling the supply of fluid to the left-hand piston 60.

Abstract: 1,160,703. Touch detecting circuits. BEHAVIOURAL RESEARCH & DEVELOPMENT Ltd. 11 Aug., 1967 [19 July, 1966 (2)], Nos. 32280/66 and 32282/66. Heading H3B. A screen 1 on which a display is projected carries one or more transparent conducting films 2 on its surface. Each film is connected to a different detecting circuit comprising a voltage divider R1, R2, double triode 3, cold cathode tube 4 and relay 5. Resistors R 1 , R 2  have a high impedance so that the current drawn through film 2 when touched is less than 15 ÁA. The negative pulse generated when the film is touched is inverted and amplified by the double triode, and causes triggering of the coldcathode tube. When a plurality of films 2 is provided the cathodes of the various coldcathode tubes are interconnected by inhibition circuits so that firing of one tube prevents firing of any of the others.

Abstract: 970,615. Machine tool details. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. Aug. 22, 1962 [Sept. 1, 1961], No. 32301/62. Heading B3B. The invention relates to a relay circuit for co-ordinating the operation of two switching systems each controlling a sequence of operations of a machine tool. Sequence control systems comprises two identical arrangements A and B of three bank stepby-step switches and plug-boards. Relays such as 4a, 5a (controlling e.g. rapid traverse advance and return) are connected to appropriate step-on plug-board PWa2 associated with bank SWa2. Limit switches on the machine such as Ea1 Ea2 are connected to corresponding steps on bank SWa3 to energize reply relay 7a when the required e.g. traverse has been made; 7al open de-energizes the control relays 4a, 5a; 7a2 releases a repeater relay 3a to de-energize the operating coil SWa to advance the selector one step. This cycle then repeats. Co-ordinating control.-Assume it is required to hold system A at step 2 until B reaches step 5. Auxiliary relays 1a 1b are plugged into contacts 2 and 5 respectively on selector banks SWa1, SWb1 When A reaches step 2, relay 1a is operated to change over contact 1a2 releasing relay 2a which completes a holding circuit for relay 3a over 2a1 down and 3a2 up, so that the selector switch is not advanced when relay 7a is energized at the completion of sequence 2. The holding circuit is maintained until system B reaches step 5 to operate relay 1b changing over contact 1b2 to re-energize relay 2a again.

Abstract: 889,709. Vehicles equipped with lever-arm machines for loading. BABCOCK & WILCOX Ltd. Sept. 23, 1960 [Sept. 23, 1959], No. 32392/59. Class 78 (4). [Also in Group XL (a)] Debris which has fallen into a coolant duct 2 entering the bottom of the pressure vessel of a gas-cooled nuclear reactor is removed by a remotely-controlled carriage 12 which, after depressurization of the reactor, is advanced along a track 10 through an axuiliary duct 4 and into the duct 2. The carriage 12 is controlled from a position behind a shielding wall 50 in a chamber 7 adjacent a biological shield wall 6 and before the carriage is brought into the chamber a pair of plugs (Figs. 2, 6, not shown) are extracted from the duct 4 by a winch 51 and pulley 52 and deposited by a crane 24 in a pair of holes 40, 42. The carriage 12 (Figs. 7, 9), is supported on the track 10 by wheels 98, 100 and has a turret 110 supporting a jib 112 and a television camera 114. A rotatable grab head 118 on the jib carries a jaw 120 and the carriage 12 carries lights 116. Extending lengthwise along the carriage is a removable canister 92 and within the canister is a trough 134 which may be projected for. wardly relatively to the canister to the position shown in chain-lines in Fig. 7 by a reciprocable rack 136 mounted in the carriage. The rack is detachably connected at its forward end by a catch 148 to the trough 134 and has rollers 146 engaging the track 10. The movements of the carriage and the above-mentioned movable members and devices mounted thereon are controlled by electric motors the cables of which are wound on to a pay-off drum 70. In use, the carriage 12 with its jib 112 in the retracted position, shown in chain-lines in Fig. 7, is advanced through the duct 4 and when in the duct 2 the jib is rotated to project forwardly. The camera 114 is moved to keep the debris in view and the carriage is stopped, the jib is lowered and the jaw 120 operated to grasp the debris which is then raised. The trough 134 is projected beneath the jaw and the debris deposited therein, the trough then being retracted. This procedure is repeated until all the debris is in the trough. The carriage 12 is returned to the chamber 7 where the canister 92 is lifted from the carriage into an upright position, shown in chain-lines in Fig. 1, and dropped into a coffin 74, the coffin being subsequently removed to a cooling pond. In falling into the coffin the canister passes through braking means comprising a rubber ring. The means for lifting the canister into the upright position are described with reference to Fig. 10 (not shown). In a modification (Figs. 12-17, not shown), the canister and trough are omitted and the carriage 12 carries a vacuum cleaner for the removal of dust or small particles from the duct 2, the nozzle of the vacuum cleaner being held by the jaw 120.

Title: Improvements in or relating to fluid pressure brakes
IPC: B60T15/04
Filed: 1931-11-25
Abstract: 379,160. Fluid-pressure brakes. HOLMBERGS MEK. VERKSTADS AKTIEBOLAG, C., 10, Bangatan, Lund, Sweden. Nov. 25, 1931, No. 32730. Convention date, Sept. 14. [Class 103 (i).] A vehicle fluid-pressure break comprises a regulating slide valve 13 operated by the driver and controlled by the pressure in the auxiliary reservoir 10, Fig. 4, in single chamber brakes or in the function chamber of 6, Fig. 1, of twochamber brakes and by a spring 16 which in inoperative position determines the maximum braking pressure and is held compressed by a spring 25 the effect of which is controlled by the control pedal 19. The spring 25 by means of a lever 21 pivoted on a link 23 holds the spring box 7 of the spring 16 against a stop. The two chambers 6, 8, Fig. 1, of the brake cylinder of the two chamber brake and the reservoir 10 are fed from the main reservoir 2 through pipe 3 cavity 14 in the slide 13, pipe 5 and feed groove 12 until the pressure in the brake cylinder and the reservoir and consequently in the interior of the slide 13 derived through ports 37 overcomes the spring 16 and moves the slide to cut off the connection between pipes 3, 5. This pressure will be the maximum braking pressure and is thus controlled by the spring 16. Depression of the brake pedal takes up lost motion 26, extends the spring 25 and relieves the tension of the spring 16, allowing the fluid pressure on the slide to move it still farther to the right and connect the chamber 6 to an atmospheric port 11 by the cavity 14. The pressure in the chamber 8 applies the brake, until the tension of the spring 16 overcomes the fluid pressure on the slide and returns it so as to cut off the atmospheric port 11. In this way a graduated application is obtained and similarly by releasing the pedal a graduated release and recharging is obtained, the spring 25 returning the slide to the left hand position, the slide then being returned to the middle position by the recharging pressure at each stage of release. The tension of the spring 16 also moves the slide to the left to compensate for any leakage. In a single chamber brake the main reservoir 2, Fig. 4, feeds the auxiliary reservoir 10 by means of the cavity 14 and the brake cylinder 34 is connected to the exhaust port 11 by a cavity 15 in release position until the pressure in the interior of the slide compresses the spring 16 and cuts off these connections. Operation of the brake pedal and thus release of the spring pressure allows the slide to connect the auxiliary reservoir to the brake cylinder and apply the brake until the slide is returned by the spring 16 against the reduced pressure. Graduated application and release is obtained with this modification also.

Title: Improvements in or relating to electrical devices for indicating the presence of gases and suspended foreign matter therein
IPC: G01N27/66
Filed: 1937-12-01
Abstract: 493,670. Electric tests. JAEGER, W. Dec. 1, 1937, No. 33147. Convention date, Dec. 2, 1936. [Class 37] In apparatus for detecting gases and testing them for the presence of foreign matter, wherein the gas under test is contained in or passed through an ionization chamber, the change in potential of an electrode within the chamber is measured to indicate the condition of the gas. Fig. 1 shows an ionization chamber 1 through which the gas flows by way of inlet and outlet ports 6, 7. The gas is ionized by radio-active material 5. A battery 9 is connected to electrodes 2, 3 and the variation in the current flowing between them varies the potential of a test electrode 4. The potential of the electrode 4 relative to the electrode 2 is measured by the electrometer 8 which gives an indication of the condition of the gas. By placing a high resistance, Fig. 2 (not shown), in the connection between the battery 9 and electrode 3 the potential of the latter will vary with the current; the electrode 4 is then dispensed with and the electrometer connected between the electrodes 2, 3, to give the required indication. This resistance may be replaced by a second ionization chamber operating substantially at total saturation or by a chamber with a glowing or photo-.electrode operating substantially at total saturation whereby the current flow is maintained substantially constant. To prevent deposits of foreign matter from the gases under test upon the insulation of the test electrode 3, for example, the electrode 3 is rigidly held in the chamber 1 by the insulation 11, Fig. 5, in a further chamber 24. A ring 17 and wall 18 prevent the gas stream through chamber 1 entering the chamber 24 and a current of air which may be heated or dried, for example, by a heating coil 21 is directed upon the insulation 11 to keep it clean. This air current escapes through a port 20, or, if this is dispensed with, through the chamber 1 and port 7. It may be drawn into the chamber 1 by vacuum. The heating coil 21 may in addition heat the insulation 11 to prevent condensation of moisture upon it, and may be replaced by other forms of heating apparatus, for example, heat may be radiated through a window from outside. the chamber or the whole chamber may be heated.
