Title: Improvements in internal combustion engines having scavenging and combustion air pumps
IPC: F02B75/28
Filed: 1921-11-05
Abstract: 171,115. Junkers, H. Nov. 8, 1920, [Convention date]. Two-stroke-cycle engines. -A pump piston, formed integral with or attached to one working piston, supplies scavenging air to a reservoir surrounding the cylinder and thence to the working cylinder. Engines are described in which two pistons reciprocate in opposite directions in the same cylinder. In Fig. 1, a piston 2 carries the pump piston 4, and scavenging air is compressed in the crank chamber 15 and transferred through valves 17 and ports 23 to the reservoir spaces 20, 24. Admission and exhaust ports 12, 13 are formed in the cylinder. In Fig. 2 the pistons are connected to the same crank shaft. The pump piston 4 is attached to the crosshead 7, which may work in slots in the cylinder wall at 1<1> to reduce the height of the engine. The air may be conveyed to the reservoir through a passage 18 or through valves in the piston as in Fig. 1. In a further modification, the piston rods 11 work in glands in the partition 22, the space 20 alone being used as the reservoir. Fuel is introduced at 14. The pistons are prevented from rotating by a recess in the scavenging piston engaging a projection on the casing. The baffles 22 tend to prevent loss of lubricating oil splashed by the cranks. In multicylinder engines, the reservoirs of the several engines may be interconnected to reduce the variations in pressure.

Abstract: 1,218,582. Testing pneumatic tyres. DUNLOP CO. Ltd. 21 June, 1968 [4 July, 1967], No. 29611/68. Heading B7C. A method of testing vehicle tyres comprises rotatably mounting a tyre 2 on a beam 6, pressing said tyre against a rotatably mounted drum 1, the rotational axes of the tyre and drum being horizontal and spaced apart, rotating the drum and measuring the resultant force acting on the beam parallel to the rotational axis of the tyre. The drum 1 is mounted on a rigid framework 14 by a motor 5 through a torque gauge 4, while the beam 6 is trapezoidal in plan and is pivoted about a horizontal axis at 9. A vertically downward force applied by means 16 is measured by the pressure gauge 17, and tension/compression transducers, only one 10 being shown, measure the force acting on the beam parallel to the rotational axis of the tyre. In a modified form of the invention a tension/ compression gauge may be mounted between the wheel 2 and the transverse beam member (6a) adjacent thereto.

Tool-holders; boring-heads; milling-cutters.-A tool for a lathe, boring or milling-machine &c. comprises a body 10 having a recess 12 to reoeive a shank on a high speed steel bit 11, the bit being secured by a wedge 13 operated by a screw 20. The wedge lies in a recess 14 in the body and has side lugs 16 which enter a tapered opening formed between the rear inclined face 17 of the bit and the forward surfaces 18 on the outer abutments 15 of the holder. The rear surface of the recess 14 is parallel to the axis of the screw 20 so that the thrust as the bit is transmitted directly to the abutments 15 and does not affect the screw or tend to rotate the wedge in a horizontal plane. The wedge is pressed downwards by a collar 22 on the screw and is withdrawn by a collar 23 attached to the screw by a pin 24. When constructed as a milling-cutter a single bit may be attached to an arbor to act as a fly-cutter or several bits may be mounted in a body by means of the wedges 13.

Abstract: 922,164. Thermonuclear apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. Aug. 18, 1961 [Aug. 26, 1960], No. 29836/61. Class 39 (4). A plasma heating and containment apparatus of the pinch class comprises first and second spaced apart electrodes for establishing a selfconstricting gaseous electrical discharge, means for providing between the electrodes a magnetic field which is symmetrical about an axis extending between the electrodes and which has a reduced intensity at a region between the electrodes, the field being oppositely directed at each side of the region, and means for increasing the intensity of the field following the formation of the discharge. In Fig. 1, a generally cylindrical tube 7 of quartz or the like is closed at each end by electrodes 14, 16, the electrode 16 being connected by a plurality of conductors 21 to a terminal ring 22 disposed coaxially around electrode 14. The tube 7 is provided with a wide central portion and two narrower portions on either side of the central portion; the narrower portions cause a controlled instability of the plasma which accelerates part of the plasma towards the central region. The narrow parts of tube 7 are surrounded by coils 12 and 13 which are oppositely energized to provide a cusped containment field. The coils 12, 13 are energized from a D.C. supply 26 to establish the magnetic field shortly after a discharge has been established between electrodes 14 and 16, and may be tuned by condensers 28 and 29 to resonate at a frequency of between 5 and 10 megacycles; they may be energized at their resonant frequency by an R.F. source 31 to cause additional heating of the plasma by the Fermi effect. The timing of the initiation of the discharge and the magnetic field may be controlled by a unit 30; since the inductance of coils 12 and 13 causes delay in building up the magnetic field it is generally necessary to energize the field coils before applying voltage to the discharge electrodes.
