Title: Method and system for saving bandwidth during broadcasting/multicasting
Inventor: ARYE RAM
IPC: H03M7/30
Filed: 2007-07-24
Abstract: Multi-channel network communication is improved by reducing the amount of data that is transmitted over connections that can stem from a similar source. Content of data packets transmitted from the source are reduced and the result is compared to previously transmitted data packets. If identical packets are found, then only an identification of the packet is transmitted. At the receiving side, the identification is used to identify a previously received data packet and use that as though it was the recently received packet. If a similar packet is identified, then the identification of the similar packet, along with change information is transmitted to the receiving side.

Abstract: 849,246. Percussive tools. BROOM & WADE Ltd., BROOM, H. S., and JAMES, E. B. March 26, 1959 [April 1, 1958], No. 10494/58. Class 124. A pneumatic percussive tool having a valve operated by the ratio of supply air pressure to the pressure in the cylinder, has at least one cushioning air chamber in connection with the cylinder at the end remote from the tool steel, the connection being through a metering hole of small dimensions relative to the air chamber. As shown, a pneumatic tool has a piston 51 operating in a cylinder 12, an anvil 45 transmitting the blow to a steel 48, and a valve 28 of cup shape having a flange moving between two seatings 26a and 26b. The valve is held in position with the flange seating on 26b by the pressure of compressed air entering through a valve 18, in this position the piston is driven upwardly. When the piston head 53 passes an exhaust port 55 air is compressed above the piston and some of this pressure is relived by air passing through one or more metering holes 57 leading to cushioning air chambers 56 situated near the top of the cylinder. The air admitted to the air chambers delays the time when the pressure above the piston is sufficient to change-over the valve and admit compressed air above the piston and drive it downwardly. It is stated that the " kick " on the reversal of movement of the piston is reduced without impairing the force of the blow.

Patent GB-542385-A (GB)
Title: Improvements in or relating to aerial barrages
IPC: F41H11/04
Filed: 1941-06-21
Abstract: 542,385. Aerial warfare. WILSON, H. R. June 21, 1941, No. 10730/40. [Classes 9 (i) and 9 (ii)] An aerial barrage unit comprises a casting containing an explosive mine or weight attached by a steel cable. to a parachute which is released by aero-dynamic means, after the unit has been discharged from the aircraft so that the wires form an entanglement. In the case of a mine this is armed by the pull on the extended cable, firing being effected by subsequent impact on the mine itself, or on the cable. In the form shown in Figs. 1, 2, and 4, the casing 1 is fitted with a lid 6 which is automatically removed by the effect of air-pressure on the extending lip 7. Secured to the lid is a pilot parachute 4 and a main parachute 3 to which one end of the cable 8 is attached. The other end of the cable is connected by a rope 9, passing through a cardboard disc 10, to an eye 11 on the upper end of the mine 2. The latter is normally spaced from the casing by rubber rings 16, 18 and has a cover-plate 15 carrying the arming-device for an electricallyoperated detonator 14. The arming-device comprises a dry battery 28 the circuit of which includes the heating-filament 22 of the detonator, the cover-plate 15, a contact-plate 23 and a pair of fingers 21 connected to the casing. The plate 23 is carried by the eyebolt 11 and is moved, against a spring 24, to bridge the fingers 21 by the pull of the cable. Impact with the exposed cable or the mine casing will cause relative displacement of the mine and casing to bring the cover-plate 15 into contact with the casing and close the firing-circuit. Means may be embodied for delaying the release of the lid 6 and the withdrawal of the parachute. As shown in Fig. 5, the lid 31 is screw-threaded into the casing and fitted with inclined vanes 32 the air-pressure on which effects unscrewing of the lid. The casing may be provided with a calibrated slot for predetermined setting of the lid. To assist in the separation of the lid from the casing the latter may be provided with an oppositely-inclined set of vanes 33. If the mine grounds without firing, the pull of the cable on the eye 11 is relieved so that the spring-loaded plate 23 moves away from the contact-fingers 21 leaving the device at safety.
