Abstract: 1390985 Supporting articles N E RENAULT 23 March 1972 [30 March 1971] 13572/ 72 Heading E2B [Also in Division F3] A mobile target assembly comprises a target 1, a plate 13 which is mounted on a traversible carriage 3 and, mounted on the plate 13 front and rear springs 8, 7, each of the springs being curved and having a pointed end. The pointed ends face each other and the target 1, is held therebetween. The target is held in equilibrium by a member engaging the same at a third point. In the construction shown plates 18 are connected to the front and rear of the target 1 to facilitate engagement of the points. The front spring is pivotally mounted on the plate and the rear spring fixedly mounted. The target 1 is also urged upwardly by the member which comprises a spring which may be an extension of the front spring (as shown) on a separate spring (Fig. 5, not shown). The plate 13 is mounted on the carriage 3 by a rod 14 which forms a movable plunger in a magnetic coil when the coil is activated. The lower end of the rod 14 is formed with a pair of diametrically opposed pins which run in respective helical guides 22 so that on activation of the coil 15 the holder is raised and rotated through 180‹. This takes place on reversal of the carriage movement so that the target always appears to be facing in its natural direction of movement. The carriage runs on rails from which current for driving the carriage 3 and coil 15 is picked up. The carriage may be driven by conventional or linear DC or AC motors and a diode is placed in the coil circuit so that the coil is only activated during one direction of movement of the carriage.

[Class 110 (iii)] In a contra-rotational gas turbine plant, primary air from the compressor 11 is diverted by centrifugally acting blade portions 19, and passes through an annular space 22, past swirlproducing blades 24 into a combustion chamber 16. The fuel is thrown in a radial sheet, transverse to the current of primary air, from a valve 23 which is opened by the pressure of the fuel supply. Ignition is started by a heater 30 which withdraws into a covering tube when the airpressure on piston 31 overcomes a spring 33. Secondary air passes from the compressor into a chamber 12 and surrounds the tubes 14 which lead from the combustion chamber to the turbine 17. The secondary air enters through perforations 15 and mixes with the combustion products. In the construction shown in Fig., 6, the primary air passes through the space 59 and blades 62 and the secondary air passes through the chamber 65 and holes 64 in tubes 14. In a third form the chamber 65 is continued by a sheet metal extension and the tubes 58 are replaced by an annular passage between annular walls which are corrugated where they reach the sheet metal extension and thereby provide passages for the secondary air to enter the main gas flow.

Abstract: 679,286. Delivering measured quantites of liquids. COURTAULDS, Ltd. (Courtaulds (Canada), Ltd.). June 6, 1951 [June 7, 1950], No. 14200/50. Class 106(v) Apparatus for delivering a measured volume of liquid, in particular sodium hydroxide solution to a churn for use in the production of viscose, comprises a chamber 1 with an overflow weir 7 and an outlet 4, a pneumatically-operated inlet valve 8, a pilot valve 16 operated by a float 26 and a pressure reservoir 18 fitted between the pilot and inlet valves, from which the air exhausts slowly after the closing of the pilot valve and allows the inlet valve to close slowly. The inlet valve is normally held closed by a spring 12 but, in the lowered position of the float and, therefore, of the pilot valve, is opened by compressed air from a control valve 14. As the liquid level in the chamber approaches the semi-circular cut-out in the weir plate 7, the float raises the pilot valve to shut off the air supply and connect the reservoir with a vent pipe 22, the aperture of which may be adjusted by a valve 23. As the reservoir exhausts slowly, the liquid supply is gradually cut off and the turbulence in the tank subsides while the excess is passing over the weir plate into the pipe 6. The control valve 14 is then opened to atmosphere and the outlet valve 5 is operated manually or by automatic time control to discharge the measured quantity. A displacer 28 mounted on a screw 29 is providing for adjusting the volume measurer.

Class 79(1) In a tractor having an implement attaching linkage including upper and lower pivoted links 3, 4 and power lift means connected to the linkage, the working depth of an implement 1 attached to the linkage is regulated by spring means 12 which are arranged to provide a lifting force on the linkage when the tractor pitches rearwardly, and lost-motion is provided in the link 3 so that the tractor can pitch forwardly without exerting a lifting force on the implement through the link 3. The upper link 3 is telescopic, having a part 3b slidable in a part 3a, the latter having slots 3d engaged by.a transverse pin 3c on the part 3b, and a pair of lower links 4 are connected by lifting links 11 to lifting arms 10 on a shaft 9, rockable by hydraulic or other lift means. An arm 15 secured on the shaft 9 engages a member 14 of the spring means comprising the compression spring 12 in a housing 16 having a screwed cap 17 and adjustable axially relative to the tractor hydraulic lift housing 13 by means of a screw 18 and handwheel 19. In the normal working position of the tractor and implement shown, the spring is fully compressed and solid. When the tractor pitches rearwardly the spring 12 expands and maintains support of the linkage with a progressive reduction of the proportion of the weight of the implement which is transferred to the tractor rear wheels 20. When the tractor pitches forwardly, the link 3 which is normally under compression extends so that lifting force is not exerted on the implement through the link 3, so that the working depth of the implement is maintained. The spring means adjustment, for the working depth and the lowest, point of the implement, is effected when the linkage is raised by the power lift.

Filed: 1969-03-19
Abstract: 1,194,816. Automatic exchange systems. SIEMENS A.G. 19 March, 1969 [20 March, 1968] No. 14316/69. Heading H4K. A common decoder and a single set of access wires to exchange circuits is used by means of signals of a first sort selectively to ascertain any circuit state and, by means of signals of a second sort to effect a switching operation in any circuit. The signals of first and second sort may be pulses distinguished by amplitude or pulse length. As shown, each exchange circuit has its state ascertainable from a saturable core Ab x/y in a 16 x 16 matrix AbM of cores Ab 1/1 to Ab 16/16 of 256 such circuits. Corresponding relays An 1 to An 16/16, one in each circuit, are arranged in a matrix AnM, each relay having one winding in series in a row and another winding in series in a column in the matrix. A 4 x 4 address decoder SMS has the first windings of relays S1 to S16 energized selectively from decoder/drivers Del, De2. An address decoder SMS has the first windings of relays Z1 to Z16 operable selectively from decoder/drivers De3, De4. Second windings of relays S1 to S16 are connected in series with corresponding columns of saturable core matrix AbM while the corresponding rows of the matrix have the second windings of relays Z1 to Z16 in series. An identity in register REG sets up decoder/drivers De1 to De4, which may be thyristor saturable core circuits, the length of the drive pulses to matrices SMS, SMZ being determined by a gating pulse ST. If gating pulse ST is short, selected S and Z relays are driven over their first windings and current induced in their second windings co-ordinately interrogates a core in the matrix AbM. Read-out on a common winding to a receiver SA indicates the state of the associated exchange circuit. If the gating pulse ST is longer, the contacts of the selected S and Z relays are operated long enough in co-ordinately driving a row and column of the matrix AnM for the associated exchange circuit relay An to be operated and latched. Interrogation of a core in AbM also takes place with a longer ST gating pulse and this indication of state may be used for checking.
