Abstract: 103,301. GobÚ, A., and Diard, H. Jan. 6, 1916, [Convention date]. Two-stroke-cycle engines.-In a radial-cylinder engine in which a pump charge is compressed in one end of each cylinder, the pump spaces each deliver into their adjacent combustion space and also into the combustion space of another cylinder. The invention is particularly applicable to the type of engine shown in Fig. 1 and described in Specification 102,975. Charges enter the pump spaces, during the suction periods, through passages b which communicate with a supply passage communication being cut-off when the iulet orifice to a passage b passes out of register with a port h<1> in a stationary member h. During the movement of the pistons towards the crankshaft, a portion of each pump charge is forced through a passage b into a chamber (not shown) in the stationary member h, which chamber is open to another cylinder which is also receiving a charge from a co-axial pump. Communication between a passage b, which is about to receive a compressed charge, and the chamber in the part h is closed until the delivery pressure is higher than that in the pump into which the chamber is about to discharge.

Title: Improvements in or relating to clutches or couplings for conveying rotary motion
IPC: F16D13/14
Filed: 1944-01-07
Abstract: 577,325. Clutches. LOMBARDINI, P. C. Jan. 7, 1944, No. 355. [Class 80 (ii)] A friction clutch comprises a resiliently supported friction ring 8 on the driving member 1, 1a which engages a slightly eccentric inner surface of a drum 2a of a driven member 2, 3 in driving connection through a member 4 with the driven shaft 13. The ring 8 is carried on the driving member by a series of pressure rods 5 and springs 11 the pressure of which is varied by means of an axially slidable shaft member 7 with cam faces 7a co-operating with rollers 6 on the inner ends of the rods 5. When the spring pressure is light the friction between the eccentric drum and the ring 8 is not sufficient to convey rotary motion, the ring moving against the springs in an oscillating motion. On increase of the spring pressure the friction increases and the eccentric drum 2a is constrained to rotate with the ring 8. Torque springs 11a are also provided between the rods 5 and the ring 8 as shown. Various other arrangements of these springs are described. The operation of the clutch as shown is by a foot pedal 22 but may be automatic by arranging centrifugal weights acting through pivoted arms on to the cam shaft 7. Passages 2b, 2c are provided in the drum portion 2a for keeping the rubbing surfaces lubricated and cooled by oil retained within the casing.

Title: Regenerative amplifier
IPC: H03K3/30
Filed: 1964-01-06
Abstract: 1,043,311. Transistor pulse circuits. GENERAL ELECTRIC CO. Jan. 6, 1964 [March 18, 1963], No. 605/64. Heading H3T. A regenerative pulse amplifier comprises a transistor 11 having its load in the emitter circuit and a transformer 18 having the secondary winding 17 connected between base and emitter and the primary winding 19 connected between the emitter and a point of reference potential. The current in winding 19 is diverted to the load by the onset of the incoming pulse whereupon the regenerative coupling between windings 19, 17 causes transistor 11 to be rapidly turned on so as to provide a steep voltage step across the emitter load. As described, transistor 11 is normally non- conductive and transistor 25 conductive, passing a steady current I1 through the primary winding 19. When transistor 25 is turned off by the onset of the negative input pulse at 27, the current I1 is maintained by the inductance of winding 19 but diverted via transmission lines 16, 16<SP>1</SP> to matched loads 29, 29<SP>1</SP>. The rise in voltage at junction 33 is coupled by transformer 18 so as to turn on transistor 11 giving a regenerative voltage step across the loads 29, 29<SP>1</SP>. The rise in load voltage is limited by diode 35. Capacitor 22 now discharges and the current in winding 17 decays until transistor 11 becomes non-conductive when the voltage across the loads 29, 29<SP>1</SP> is maintained by the new value of current I1, until the end of the input pulse at 27 when transistor 25 becomes conductive, short circuiting the loads 29, 29<SP>1</SP>. The collector current is limited by resistor 36, capacitor 37 providing a large momentary current when transistor 11 is turned on.

[Class 139] Alarm mechanism comprises a slidable pinion 5 actuated by the mainspring 1 and having a face cam 9, a normally stationary pinion 12 settable by hand and having a projection 10 coacting with the face cam, two spring-controlled levers 17, 18, one arm of each pressing against the non-cam face of the pinion 5, whilst the other end 19 of the lever 17 co-operates with two stops 22 on the alarm-spring barrel 21, and the other end 20 of the lever 18 blocks a bell hammer lever 28 (or 33), the first lever 17, 19 being movable longitudinally against its spring 24, and the hammer being actuated from the alarm spring barrel 21 through a pinion device and escapement in a usual manner. The mainspring barrel 1 driving the hour hand 3, also rotates, once in twenty-four hours, a wheel 5 carrying a face cam 9 which coacts with a lug 10 on a normally stationary member 12 which may be set for the desired alarm-release time by a wheel 15 and knob 16. Bearing against the face of wheel 5 are the ends of a lever 17, 19 pivoted at 17<1> and of a lever 18, 20 pivoted at 18<1>. The arm 20 normally obstructs a screw 27 on a hammer lever 28, 29 pivoted at 28<1>. Lever 28, 29 is actuated from the alarm-spring barrel 21 by a pinion device and escapement (not shown) in a usual manner. The free end of a second hammer lever 33, 32 pivoted at 32<1> is forked to embrace the arm 28. Arm 20 is pressed down by a spring 26. Lever 17, 19 is slotted at 25 to take over pivot 17<1> ; is pressed down and to the right by a spring 24 ; and coacts with two diametrically opposite studs 22 on the alarm-spring barrel 21. When the drop in cam 9 reaches lug 10, springs 24, 26 rotate their levers clockwise and wheel 5 rises. Arm 20 releases the screw 27 and the hammers are actuated. The alarm spring rotates until the next stud 22 reaches the lowered end of the arm 19. This pushes lever 17, 19 to the left for the length of its slot 25 and the barrel is then locked. As the wheel 5 rotates further, it is depressed by the lug 10 until arm 20 once more locks the screw 27 and afterwards the end of arm 19 is raised from stud 22. Lever 17, 19 then moves to the right by the length of the slot 25 and lies alongside the stud 22 so that it can no longer arrest that stud.
