Title: Digital Data Storage System
Inventor: BARBINA VALERIO
IPC: G03B19/18
Filed: 1968-07-24
Abstract: 1,189,025. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 24 July, 1968 [16 Aug., 1967], No. 35226/68. Heading G4C. In a digital data storage system having two cyclic stores 60, 70 of different cycle time, data is transferred from a location of the store of shorter cycle time 70 to a buffer store 80a in response to an indication from address identifying means of concurrent accessibility of likenumbered locations in the two cyclic stores, for subsequent transfer to the other cyclic store 60. Each cyclic store 60, 70 has two magnetostrictive delay lines, 60a, 60b or 70a, 70b, operating in parallel, and recirculating via registers used for entry and exit of data. Data can be transferred in time-division-multiplex manner, between a computer (not shown) connected to line 1, and I/O devices 2a, 2b (via cyclic store 60), 3a, 3b (via cyclic stores 60, 70 in turn), each cyclic store having an address for each associated I/O device. Unit 62, associated with cyclic store 60, contains a clock-driven character counter driving an address counter. Equality between this address counter and a similar counter in unit 72 associated with cyclic store 70, detected at 85 permits data from cyclic store 70 to be entered into register 80a and the I/O device address to be entered into a register 80b. Agreement between the latter address and the address counter in 62, detected at 86 permits the data at 80a to be passed to the cyclic store 60. Comparison as above at 85 permits data from cyclic store 60 and a corresponding device address to be entered in registers 90a, 90b respectively, the data being passed to cyclic store 70 on equality between the address in 90b and the counter in unit 72, detected at 96. Transfer is also dependent on it being required, control bits being present in the cyclic stores 60, 70 and being transferred between the cyclic stores using the above facilities, for this purpose. Registers 80c, 90c for control bits are also provided. Drums and discs are mentioned as possible cyclic stores.

Abstract: 156,106. Fuller-Kaemmerling Engine Co., (Assignees of Kaemmerling, G. H.). Nov. 25, 1916, [Convention date]. Valves; valve-gear.-Engines using solid or liquid fuel, but solid fuel in particular, have water seals surrounding the pistons. In two-stroke engines these seals cover valves located in terminal inlet and exhaust ports but in four-stroke engines separate seals are provided for covering the valves. The twostroke engine shown in Fig. 1 has a water seal 10 which is renewed every cycle by water supplied through tangentiallyarranged ports opening into a passage 54. A pump, not shown, delivers water into a tank connected to the passage 54 in which is a cam-actuated valve 52 timed to open after the closing of the exhaust valve 17. A valve 22 is located in the outlet port of a passage 19 to which are supplied air through a valve 26, and powdered fuel mixed with air through a valve 27. All the valves are actuated by cams on a shaft 42. The water surrounding the piston escapes into the inlet and exhaust pipes when the valves in the cylinder ports are opened at the ends of the working stroke. The escaping water in the pipe 14 cools the exhaust gases. To collect the water passing through the valve 22 a passage 24 is provided in the bend of the inlet pipe. A modified construction of engine is shown in Fig. 9 in which a reciprocating camactuated sleeve valve 83 controls admission ports x, exhaust ports y, and water inlet ports 99. The water escapes through a passage 98 in the air and fuel supply chamber 80. A groove 100, which is flushed by the water seal, is located above a packing-ring 85'. The groove is drained by a pipe 102. The cylinder comprises three parts 75, 76, 77 secured together by bolts 79. According to a modified construction of the engine shown in Fig. 1, the upper portion of the piston may be reduced in diameter, the cylinder bore being uniform, or the water seal may be contained in an annular recess in the piston body. A further modified construction is described in which two adjacent pistons are acted upon simultaneously by each impulse. The terminal inlet and exhaust ports may each contain one or more valves. Also, auxiliary valves may be provided in the cylinder inlet ports for the discharge of the water. In a four-stroke engine having inlet and exhaust valves in pockets in the cylinder head, the water for the seal around the piston is admitted through one passage and discharged through a valve-controlled passage at a higher level in the cylinder. Water seals are provided above the heads of the inlet and exhaust valves.
