Title: Method and apparatus for composing and decomposing type
IPC: B41B3/04
Filed: 1928-12-24
Abstract: 304,312. Pusino, O. Dec. 24, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 20, 1929]. Setting type.-Types released from magazinechannels 1, Fig. 1, are received in tubes 2 carried on pivoted arms 4, which are mounted on curved axes, and actuated by keys to convey the types to a central channelled composing-rule 6, on which they are deposited. The types are ejected by pushers 7, Fig. 4, from the lower ends of the channels into lateral chambers 17, from which they slide through tubes 3 into the tubes 2. The tubes 3 are twisted through an angle, so that the types are delivered in proper position upon the rule 6, or a single central twisted tube 25, Fig. 3, may be used. The types are retained in the tubes 2, while in transit, by sliding U-shaped pins 5, which are retracted when the tubes come over the rule 6. The released types are pushed along the rule by a pusher 18, Fig. 3. Distributing type.-Types to be distributed are ejected one by one by a pusher 7<1>, Fig. 7, from the lower end of a channel 1<1> into a lateral chamber 17<1>, from which they fall through a tube 3' into tubes 2' carried by levers 4', the appropriate one of which is raised into operative position by depression of a key. The tubes 2<1> are closed and opened by means of sliding pins, as in the composing-machine,. On release of the key, the type escapes from the tube 2<1> into a channel 25<1>, from which it is delivered by a pusher 28<1> into a channel 6<1>.

Title: Method of making silicon carbide
IPC: C01B31/36
Filed: 1961-10-26
Abstract: A process for the manufacture of silicon carbide comprises forming a silica gel in an aqueous sugar solution, heating the solution to dehydrate the gel to decompose the sugar and form a homogeneous mixture of silica and carbon and subsequently heating under non-reactive atmospheric conditions to form silicon carbide. A gel forming silicon compound, e.g. SiI4, Si2Cl6, Si3Cl8, SiBr4, SiF4, H2SiF6, SiCl4 is added to an aqueous solution of a sugar e.g. sucrose, dextrose, lacvulose, inert sugar, lactose. The strength of the sugar solution may be such as to provide approximately three carbon atoms per atom of silicon at the time of gel formation.  The dehydration of the gel is effected at 250 DEG  C. and final heating to form SiC may be at 1800 DEG  C. in argon.

Title: Digital Data Transfer System
Inventor: ALAIMO BENJAMIN
IPC: G11B20/16
Filed: 1967-08-22
Abstract: 1,153,691. Dynamic data storage system. MINNESOTA MINING & MFG. CO. 22 Aug., 1967 [22 Aug., 1966], No. 38596/67. Heading G4C. A recording/replay system using a movable storage medium such as a magnetic tape, includes means for producing clock pulses, for controlling the passage of information to or from the storage medium at a rate related to the speed of the storage medium, and means responsive to movement of the storage medium for inhibiting the production or action of a clock pulse following reversal of the direction of movement of the medium. Two sets of clock pulses S, R are produced either by light from a source 45 passing through translucent markers on a disc 36 secured to a capstan driving, for instance, a tape and passing through markers 43 to a photoelectric cell 51 to produce pulses R and through markers 44 to a photo-electric cell 52 to produce pulses S or by turn clock tracks having pulses staggered in the manner of the markers 43, 44. The outputs from the photo-electric cells Figs. 2a, 2b are shaped Figs. 2c, 2d and differentiated Figs. 2e, 2f. The pulses are then fed to a flip-flop 55 formed from NOR gates A, B and NOR gates C, O. Data from a computer or processor is read to a buffer memory generally at a non-uniform speed. The data is stored then passed to a write buffer to be supplied to write heads at a rate determined by the speed of the storage medium. The number of characters stored in the buffer memory is indicated by a counter 32 incremented whenever a new character is received and decremented by a clock pulse causing read out of a character. The count is supplied to a D/A converter used to control the speed of the storage medium. When data is being recorded an R pulse sets the flip-flop, producing "O" from A and "1" from B and supplying a "0" to one input of O. When an S pulse occurs it is inverted and appears as "0" at the other input to O so a clock pulse appears at the output 20 and causes a character to be supplied to the write heads and resets flip-flop 55. If the tape is stopped e.g. caused by the number of characters stored in the buffer memory dropping below a predetermined minimum, it is possible that the tape would oscillate about a marker causing an S pulse and so produce a plurality of S pulses at a rapid rate. However in this system no R pulse is produced to set the flip-flop and so no S pulse can pass gate 0. The drive system must, however, be maintained to stop the medium such that an S and an R pulse cannot both occur after the stop signal has commenced.

[Also in Division G3] The flow of liquid through a drop pipe 31 into a vessel is controlled by a valve 34 movable between a closed position in which the liquid can flow at a limited rate through an opening 42 and an open position in which the liquid can flow at a higher rate, a releasable locking device 48 normally preventing movement of the valve, a pneumatic chamber 53 and means 39 responsive to the pressure in the chamber for releasing the locking device, a relief passage 54 communicating with the chamber 53 and having an outlet adjacent that of the drop pipe to maintain the pressure in the chamber 53 normal until the liquid level closes the outlet from the relief passage, and means 52, 51, 52 for applying a pressure differing from that of the atmosphere to the chamber 53 whereby the locking device is released when the outlet from the relief passage is closed. In operation, a cam lever 50 first lifts a valve 43 to permit liquid to flow through the opening 42 until the end of the passage 54 is closed, causing reduced pressure in the chamber 53 and movement of the diaphragm 39 to release the locking device 48. Continued rotation of the cam lever 50 now lifts a second valve 47 to equalize the pressures on opposite sides of a plunger 35 attached to the main valve 34 and subsequently lifts the main valve itself. The passage 52 may be telescopic, as shown, or may be formed by spirally wound flexible tubing and the passage 54 may be closed by a float or solenoid-actuated valve, the solenoid being energized when the vessel has been earthed. In a simplified construction, the valve (4, Fig. 1) is secured to a horizontal spring-loaded spindle (5) controlled by the locking device (20) and has permanently open passages (7, 12) to reduce the pressure in the chamber (13) when the relief passage (21) is closed by the liquid level in the vessel being filled.
