Title: Improvements in and relating to circular knitting machines and circular-knit fabric
Inventor: BOOTON HERMAN
IPC: D04B9/46
Filed: 1957-08-27
Abstract: 895,672. Knitting. BOOTON Ltd., W. E. Aug. 13, 1958 [Aug. 27, 1957], No. 26947/57. Drawings to Specification. Class 74 (2). A two-feed circular machine has provision for rendering one feed operative or inoperative and simultaneously effecting needle selection such that the incoming or outgoing yarn at that feed is tucked on alternate needles thereby avoiding eyelet formation at the point of introduction or discontinuance of the yarn. The yarn is also taken by the intervening needles and knitted by those needles together with the yarn taken but not knitted at the other feed. When it is intended to commence or discontinue using a yarn the stitch cam or part of it at the main feed is partly withdrawn so that the intervening needles of the group take yarn at that feed but do not knit it. The alternate needles on the other hand do knit the yarn at that feed but subsequently neither of the needles of the group are raised to clearing height. At the subsidiary feeder all of the needles of the group take and knit the incoming or outgoing yarn with the result that the intervening needles knit the subsidiary yarn and the main yarn together drawing loops through the previous course loops whilst the alternate needles merely take the yarn at the subsidiary feed and hold it in its hook together with the loop formed at the main feed. Subsequently all the needles of the group are cleared and the next course knitted at the main feed with the result that the end of the yarn is secured in the fabric.

Title: Apparatus for hyphenation of words
IPC: G06F40/191
Filed: 1976-06-30
Abstract: 1508736 Apparatus for hyphenating words INTERNATIONAL BUSINESS MACHINES CORP 30 June 1976 [16 July 1975] 27316/76 Heading G4A To determine where, if at all, an input word may be hyphenated, all possible hyphenations of it are converted into a coded representation and compared with stored allowable hyphenations (if any). As described each letter of the word with a hyphen added by unit 6 (Fig. 1) is converted to a numeric value L N  and a magnitude Y<SP>2</SP> = #L<SP>2</SP> N  computed and stored in register 17 to provide the address for memory 38 at which allowable hyphenations are stored. If no data is stored at this address a flip-flop 42 is set to indicate no valid hyphenation. Otherwise stored angles representing valid hyphenations are read out to angle storage buffer 45 and angles for the input word are computed. This is effected by successive runs of the input word with a hyphen inserted, in the first run after the first vowel (detected by unit 5) and in subsequent runs with the hyphen stepped along one letter. Each hypenated word held in buffer 15 then has its value Y<SP>2</SP> computed and an angle derived by (1) multiplying each of its numeric values L N  by an independent value R N  representing the position of the character or hyphen in the word and forming the sum #R N .L N , (2) computing a magnitude value R<SP>2</SP>=#R<SP>2</SP> N  and (3) supplying a computed value |R| |Y| /#L N R N  to an arcsecant calculator 29. The resulting angle is stored in buffer 43 and the process repeated with the hyphen in its next position until all possible angles have been computed. The computed angles are then compared with the stored angles held in buffer 45 and at equality a flag register is set to control read-out via gate 50 of valid hyphenated words held in buffer 15.

A movable wall portion 42 of the working chamber serves as valve means to selectively vent gas trapped between rotors 12, 14 back into cavity 102 thus to regulate the compressor capacity. Intermediate housing has bearings 54 for the high-pressure ends of rotors 12, 14, a high-pressure casing 114 being removably attached to housing 30. Casing 114 defines a cavity 116 in communication with outlet 78 and has an outlet 120 for the compressed gas. A piston 72 is attached via webs 74 to movable wall portion 42. Normally, highpressure in chamber 76 serves to move piston 72 and portion 42 to the right as in Fig. 3 due to the larger surface area of piston 72. A spring 90 also biases portion 42 to the right thus creating a vent between an edge 44 of housing 16 and portion 42. Hydraulic fluid from the lubrication and cooling system can be fed to chamber 70 to close the vent. A piston 62 attached to end 63 of rotor 12 is acted upon by pressure from the lubricating system in chamber 60 so as to balance fluid-pressure forces on the highpressure end 64 of rotor blades 22. The casing can be fixed in position relative to a prime mover which drives end 66 of rotor 12. It can be maintained in this position while the rest of the compressor is detached therefrom for servicing. The lubrication system, which is also used to inject liquid into the working chamber to cool the gas being compressed, is described in detail particularly with reference to Figs. 7 and 7A (not shown).
