Abstract: 341,801. Electromagnetic relays. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm.- (Assignees of Blomberg, K. H. ; 39, Lokattsvagen, Appelviken, Sweden.) April 14, 1930, No. 11803. Convention date, April 15, 1929. [Class 38 (v).] In a time relay, in which the delayed action is caused by the charging of a condenser C<1> through a high resistance r<1> from a source E, the condenser C<1> during its charging is connected in series with one or more condensers C<2> which have previously been charged from the same source, the arrangement being such that when their added voltage exceeds the operating voltage of a discharge device G, a discharge takes place through this and the coil R<2> of the relay. By this means a source E may be used of lower voltage than the operating voltage of the device G. In the arrangement shown in the Figure, the condenser C<2> is normally connected across the source E and charged to its potential. On energizing a coil R<1>, contacts 1, 2 are opened and contact 3 closed. The condenser C<1> is thus connected across the source and charges up slowly through the resistance r<1> till the relay R2 is operated. The relay R<2> may operate a contact 4 which maintains a circuit through it until the coil R<1> is deenergized. Two condensers C<2>, normally connected in parallel to the source E, may be used (Fig. 2 not shown) or more than two may be used. If desired, the arrangement may be such that the condenser or condensers C<2> are only connected to the source E just before the timed action commences.

Title: Improvements in or relating to friction clutch control devices for motor vehicles
IPC: F16D25/12
Filed: 1962-03-30
Abstract: 995,498. Clutch control. FABBRIKA ITALIANA MAGNETI MARELLI S.p.A. March 30, 1962 [April 1, 1961], No. 12263/62. Heading F2L. An electro-pneumatic clutch control for a motor vehicle comprises an electrically operated valve A which on closure of a gear shaft lever switch 27 supplies pressure air from a source 9 through a check valve 11 to a clutch disengaging servomotor 6 and to a servomotor 13 which reduces throttle opening, and further electrically operated valves B, C which when the clutch is disengaged connect the pressure air source 9 to the servomotor 6 through an engine speed responsive valve D so that on establishment of a gear ratio and consequential de-energization the valve A which vents the servo 13, the servo 6 is maintained energized through the valve D until the engine speed attains a predetermined value whereupon the valve D vents at 24<SP>1</SP> the servo 6 for clutch engagement. The valve D has inlet and outlet chambers 20, 22 respectively connected through lines 8, 18, 19 and valve B to the pressure source 9 and through lines 21, 23, 10 and valve C to the clutch servo 6. When the engine speed is below the predetermined speed there is, as shown, free communication between the chambers 20, 22 and the exhaust port 24<SP>1</SP> is blocked. When the engine speed attains the predetermined speed a governor 7 moves the valve spool 24 left to cut communication between the chambers 20, 22 and open the exhaust port 24<SP>1</SP>. Initial clutch engagement tends to reduce the engine speed and thus close the exhaust port 24<SP>1</SP> whereupon the rate of clutch engagement is also reduced. A valve E energized on closure of a switch 29 during overrun of the clutch output member supplies pressure air to a servo-motor 30 which increases throttle opening thus facilitating downshift. The valves B, C are energized on closure of a switch 28 effected when the clutch is completely disengaged. The usual ignition and manual override switches 25, 26 are provided.

Title: Improvements in jet propulsion nozzles
Inventor: SCHAEFER ROBERT HAROLD
IPC: F02K1/12
Filed: 1958-04-18
Abstract: 884,587. Jet propulsion plant. GENERAL ELECTRIC CO. April 18, 1958, No. 12452/58. Class 110 (3). A convergent-divergent nozzle for the jet pipe of a jet propulsion engine comprises a variable area convergent nozzle for subsonic gas flow combined with an air wall provided by means of an exterior passage surrounding the convergent nozzle and itself terminating in another variable area nozzle, the air wall defining an adjustable divergent passage for supersonic flow. The convergent portion of the nozzle is defined by adjustable nozzle flaps 11 hinged at 16 to the rear end of the tail pipe 17, while the boundary of the divergent portion is formed by secondary air flowing through an annular passage 15 between the tail pipe and an outer casing and emerging between the flaps 11 and the adjustable shroud flaps 12 which are hinged at 18 to a tubular shroud 19 which is itself axially slidable within the outer casing 21. Hydraulic actuators 22, 31 vary the angularity of the nozzle flaps 11 and the shroud flaps 12 respectively while an hydraulic actuator 39 varies the axial position of the shroud 19 in the outer casing 15. A control 46 combines measurements of rotor speed, throttle setting, compressor inlet temperature and pressure and turbine discharge temperature and pressure and controls the actuators accordingly. The flow of secondary air created by the ejector action of the nozzle may be used to cool engine accessories placed in the passage 15. In another embodiment (Fig. 4, not shown) a single shroud displacing actuator is used, the nozzle flaps and the shroud flaps being linked mechanically to each other and the outer casing 21 so as to move angularly as the axial position of the shroud 19 in the outer casing is varied. In a further embodiment lacking the axial adjustment the shroud flaps are hinged directly to the outer easing and are mechanically linked to the nozzle flaps, a single controller varying the angularity of the flaps.
