Title: Internal Combustion Engines.
IPC: F02B67/04
Filed: 1967-01-03
Abstract: 1,156,112. Purifying exhaust gases; compressors; reciprocating pumps. FORD MOTOR CO. Jan.3, 1967 [Jan.24, 1966(2)], No.204/67. Headings F1A, F1B and F1N. An I.C. engine comprises a valve operated by a reciprocatory valve operating member, a diaphragm 34, Fig. 2 located to form a chamber inside a valve cover and arranged so that reciprocatory movement of the valve operating member causes movement of the diaphragm to vary the chamber volume thereby inducing fluid-flow into and out of the chamber. The reciprocating motion of rocker arm ends 22a, 22b Fig.2, flexes diaphragms 34a, 34b so that air drawn in via the respective one way check valves 46, 48 passes via flap valves 42, 44 into reservoir 40. A charge of air from chamber 36 passes via passage 54 to exhaust passage 20 to oxidize the unburnt hydrocarbons present at the beginning of the exhaust phase and similarly a charge from chamber 38 passes into passage 20 towards the end of the exhaust phase. In a modification a diaphragm (34<SP>1</SP>, Fig.3, not shown) co-operates with cover (32) to form an additional pump chamber adjacent intake valve rocker arm (60). In another embodiment a rocker arm-mounted stud (138, Fig.4, not shown) activates a flexible diaphragm (134) bonded to the rocker cover (132). The charge of air passes from the chamber (136) to the exhaust passage (120) through a one-way valve (140), mounted in the cover (132), and external tubing (142). In a modification of this embodiment applied to a multi-cylinder engine air is transmitted from the pump chamber of one cylinder to the exhaust passage of another cylinder, the diaphragms also being activated from the inlet valves. In another embodiment the diaphragm 134, Fig.7 (not shown) is snapped into an opening in cover 132 to form an integral pump chamber 136 having an inlet disc valve 166 and outlet ballvalve 148. The pump may be used for pumping an engine lubricant.

Title: Improvements in methods of and tools for joining package and like wires by intertwisting
IPC: B65B13/28
Filed: 1921-01-07
Abstract: 156,745. Wirebounds Patents Co., (Assignees of Davidson, B. J.). June 30,1919, [Convention date]. Twisting wires together; angular bending; breaking.-In a method of twisting together the ends of wires placed round boxes, bales, bundles, packages &c., the wire ends are protected in the same direction from the package, &c., are held adjacent thereto and are gripped at a distance from the package by members which are rotated to twist the wires together and automatically to sever them at the tip of the twist. In the form of tool shown for carrying out the method the twisting head 3, which is bored at 4 to receive the wires, is provided at a distance from the end with two transverse steel pins 5 of slightly larger size than the wires and spaced apart a distance preferably 10 per cent more than the diameter of a single wire. The wires to be twisted together are bent parallel from the box as shown in Fig. 12, and then, as shown in Fig. 6, passed through the bore of the head, which is slightly larger in diameter than the two wires, the end of the head holding the wire against the box, &c. When the tool is rotated, the wires are twisted uniformly along the length between the box a and the pins so as to tension each turn uniformly, and when due to the tightening of the convolutions further twisting is resisted, continued rotation causes severance of the wires at the tip of the twist and a blunt end is formed as shown at Fig. 8. The. bore of the head confines the twist and prevents buckling thereof after completion. The wire required for the twist is preferably drawn first from that round the box until it becomes taut and then from behind the pins. The corners at the end of the head are rounded off to prevent, obstruction by the wire during operation. The binding wire b is stapled to the box and one projecting end is bent to the form shown at b<1> by applying thereto at a distance. from the edge of the box a notch on the under side of the head and pushing down the tool. The other end is bent as at b<2> over a notch 6 in the top of the tool. A metal butt 9 is provided for hammering down the twist parallel with the side of the box.

Title: Improvements relating to Clutches.
Inventor: COCK CHRISTER
IPC: F16D13/26
Filed: 1918-01-17
Abstract: 122,250. Ter Cock, C. Jan. 17, 1918. Clutches, friction.-In cone and plate friction clutches of the kind in which a central operating- sleeve is arranged between main operating-springs and cushion springs arranged to ensure the gradual engagement and disengagement of the clutch, the main spring is so shaped as to lie normally on or near the surface of a cone. In the form shown in Fig. 2, the operating-sleeve E is arranged between a main conical spiral spring M, bearing against the cover of the driving flywheel W, and cushion springs C bearing against a clutch cone R sliding on the driven shaft T. During the first part of the engaging movement of the sleeve E, the clutch pressure is produced by the springs C, the sleeve E subsequently contacting with the cone R to employ the pressure of the spring M. During disengagement, the pressure of the spring M is first removed, bolts 20 secured on the sleeve E subsequently producing positive disengagement. The spring M may be replaced by a series of leaf springs M, Fig. 5, arranged tangentially or radially to a carrier 3. Both main and cushion springs may be of the conical spiral type and may bear on parts connected to the operating sleeve and movable clutch part, respectively, by rods provided with suitable stops. The invention is shown applied also to a Weston-type plate clutch, in which instance the sleeve E is moved towards the fly-wheel W for disengagement. During disengagement, the main springs may move into or past the position in which they lie entirely in one plane.

Title: Switching power supply
Inventor: INAO KIYOHARU
IPC: H02M3/28
Filed: 1993-01-05
Abstract: PURPOSE:To reduce the delay of control signal of an FET to follow a high switching frequency and to cope with a large current output by providing an auxiliary power supply for obtaining the high potential for driving the FET and a synchronizing signal generator for generating a synchronizing signal with a special waveform in a follower output circuit. CONSTITUTION:In a follower output circuit 10, a synchronizing signal generator 11 outputs a synchronizing signal Vc with a saw-tooth shape which transits repeatedly with a certain inclination from the ON point of a main switch Q to the next OFF point. On the other hand, an error amplifier 14 outputs a comparison signal Vk between a follower output voltage V2 and a set voltage Vs. Also. an auxiliary power supply 12 generates a DC voltage which is higher than the potential of a source point A of an FET Q2 and is at the voltage level for driving the FET Q2. Then, a PWM circuit 13 generates a PWM signal Ve from a synchronizing signal Vc and a comparison signal Vk with the DC voltage Vec as a power supply voltage, turns on or off the FET Q2, and then maintains the follower output voltage V2 at a set voltage Vs.
