Title: Digital Data Processing System
Inventor: MENDELSON MYRON JEROME
IPC: G06F9/355
Filed: 1967-04-27
Abstract: 1,178,065. Data processor. SCIENTIFIC DATA SYSTEMS Inc. 27 April, 1967 [29 April, 1966], No. 19507/67. Heading G4A. A data processor having a memory containing individually addressable word storage locations includes means for specifying a portion only of a word and means to restrict processing of the word to the portion, thus specified. As described, 32 bit or 4 byte words are held in a memory 10, read-out to or written-in from an M register under control of access control 11 to which the address of the memory location to be used is fed from a P register. A word readout can include an operation code Op, a portion specifying an R register, a portion X specifying an index register and a word address portion (Fig. 3, not shown), R and X registers being held in a fast access memory 12. A word is transferred from memory 10 to the D register where the X field is examined to see if indexing is required. If not, the address passes directly to the P register and thence to the access control to access the next word. Otherwise the address portion passes to an ADDER and the X field to INDEXING to access the appropriate register in the register memory. In some cases it is possible that a whole word of data may not be required from memory 10. For instance, a half-word or a byte may be sufficient. In cases like this the operation code specifies which is required, a byte, a half-word, a word or possibly a double word. The contents of the index register specified are passed through an alignment control which operates in accordance with Operation codes. If a word is to be accessed, the contents of the index register pass into the A register, if a half-word the index register word is shifted one position so that its least significant bit enters the two-bit PA register the rest of the word entering the A register, if a byte the index register word is shifted two positions so that the two least significant bits enter the PA register. Similarly, for a double length word the index word is shifted the other way since only every other address is directly accessed in that case. The bits in the PA register, determine which half of the word or which of the four bytes is to be accessed; the bits being PA 0  and PA 1  and enabling the gates shown in Fig. 5 to pass the appropriate portions of the word to the D register. If both bits are 0, and all the word is required, gate 151 is enabled and the Op register signals 1931 enable gates 152, 153 and 154 to pass all portions of the C register to the D register. If both bits PA 0 , PA 1  are O and a half-word is required as indicated by a signal on line 1921 then only gates 152, 151 are enabled passing bytes C 0  and C 1  to positions Dg and D 1 . If PA 1  is 1 then gates 156 and 158 are enabled passing bytes C 2 , C 3  to positions D 0  and D 1 . Similarly, gates 151, 155, 156 or 157 can be enabled to pass bytes C 0 , C 1 , C 2 , C 3  respectively to position D 0 .

Title: Improvements in the mechanism for operating the nipper jaws in combing machines of the rectilinear type
IPC: D01G19/14
Filed: 1947-07-22
Abstract: 644,870. Combing - machines. NOUVELLE SOC. DE CONSTRUCTION CIDEVANT N. SCHLUMBERGER & CIE SOC. ANON. July 22, 1947, No. 19662. Convention date, May 7. [Class 120(i)] Mechanism for operating the movement of the nipper jaws of a Heilmann type combing machine is characterized in that an articulated element with a friction roller, operating the movement of at least one of the jaws, is maintained in contact with a cam by a spring attached at one end to the element and at the other end to an adjustable fastening device which is given a movement partly compensating for the movement of the operating friction roller or of the element with its roller in such a manner that the strain on the spring is reduced to a minimum. In Fig. 1, 4 is a lever carrying the lower nipper jaw 2. Movement of this lever is controlled by the cam 12 through a roller 10, adjustable on the lever 8, which is pivoted at 9 and which is connected by a rod 7 to the lever 4. A spring 17 is connected at its upper end to the lever 8 and at its lower end by means of an adjustable fastening member 18 to the lever 14 which is pivoted at 15 and carries at its other end a roller 16 which is also in contact with the cam 12. As the lever 8 moves under the action of the cam, the lever 14 follows up its movement to a degree determined by the shape of the cam 12 such that strain on the spring 17 is limited and excessive fatigue of the spring is prevented. A modification of the mechanism is operated by a torsion spring instead of a tension spring.

Patent GB-1368834-A (GB)
Title: Selective printing apparatus
IPC: B41J9/14
Filed: 1972-05-01
Abstract: 1368834 Printers INTERNATIONAL BUSINESS MACHINES CORP 1 May 1972 [13 May 1971] 20054/72 Addition to 1368507 Heading G4H In a modification of printing apparatus as in the parent Specification, a character is replaced in a store by an inhibiting signal when it has been printed. A tape chain moves a row of hammers spaced along the print line During each of a series of scans (a scan being divided into three subscans), each hammer in turn is aligned with one (a respective) type element, in a set option time for that hammer, each set option time being followed (before the next set option time) by a reset option time for another hammer, such that almost 2/3 of a scan occurs between the set option time and the next reset option time for a given hammer. A line of characters to be printed is supplied by a CPU on bus 176 to a print buffer 156A. A chain image store 156B indicates the characters on the type chain Rotation of a slotted drum, with the type chain, is sensed at 152, to drive a subscan counter 184 and a character (i.e. scan) counter 186. Registers DAR, IAR, RAR are initialized and updated during operation by ALU 162 fed from character counter 186, and logic (including OR 252) at the bottom left in Fig. 3, except that DAR is initialized from the CPU over bus 176 For a set option time, DAR addresses the print buffer 156A via MAR to load character into a register X, the contents of MAR also being placed in HAR to select a hammer driver via decoder 174 (which controls gates 210, 212 at the bottom right of Fig 3) The IAR addresses chain image store 156B via MAR to load a character into register Y. Registers X, Y are compared in ALU 162 and if equal, produce a "compare" signal which sets a latch 206 in the appropriate hammer driver via the gate 210 selected by decoder 174. The "compare" signal controls AND 236 (at left in Fig 3) to write an invalid character in place of the character just printed in print buffer 156A. For a reset option time, RAR addresses print buffer 156A via MAR to load register X, the contents of MAR also being placed in HAR to select a hammer driver via decoder 174. The selected hammer driver is reset via AND 224 (middle bottom of Fig 3), provided that the invalid character is not recognized in register X by AND 234 (middle bottom of Fig. 3), each recognition inhibiting the hammer reset and, via AND 238 (middle left of Fig. 3), replacing the invalid character in print buffer 156A by a character which will not satisfy AND 234. Thus a hammer driver, once set, will be reset about 1 2/3 scans later rather than 2/3.

Title: Improvements in or relating to tape recorders
IPC: G11B25/06
Filed: 1957-06-26
Abstract: 825,111. Phonographs. MEYER, R. C. June 26, 1957 [June 29, 1956], No. 20094/57. Class 40 (2). Recording-reproducing apparatus, wherein a sound head wheel 14 rotates at least two peripherally-spaced sound heads transversely of a tape 11 guided so that a transverse cross-section thereof lies adjacent the path of the sound heads, has a tape feed device 17 consisting of a friction feed wheel 18 against which the tape is pressed by a presser roller 20, and which has a number of recesses 18A, Figs. 8 and 11, co-operating with a driving worm 19 rotating with the sound head wheel 14. The feed-wheel 18 may be cylindrical, Fig. 11, for use beyond the curved run 12 of the tape, or of barrel shape, Fig. 8, to fit the curved part 12, a continuous tape-gripping edge surface being provided on both sides of the row of recesses 18A; it may be of a single material having a low coefficient of friction relative to the worm 19, or of a core of such material (e.g. tetrafluoroethylene or polytrifluorochloroethylene) surrounded by a jacket, Fig. 8, or outer discs, Fig. 11, having a high coefficient of friction relative to the tape. The roller 20 may be such as to adapt itself to the shape of the wheel 18, and the whole device 17 may be located before the wheel 14 in the direction of tape travel from a supply reel 10 to a take-up reel 13, or may be duplicated below the worm 19 to feed a second tape past the lower part of the sound head wheel 14. The wheel 18 may be disengageable from the worm 19 to allow of tape wind-back by means which also lifts the presser shoe 16; re-engagement of the gears 18, 19 automatically re-aligns the record track with the heads. The shoe 16 may be grooved opposite the head track, or may include two spaced, separately spring-loaded parts, one on each side of the head track. The wheel 14 may have three heads slightly projecting beyond the rims of two mounting discs 5A, or the heads may be cantilever-mounted on a single small disc housed within fixed partcylindrical guides which support the tape on either side of the head track. Flutter arising from the reduction gearing in the synchronous motor unit 29 may be eliminated by a flexible coupling 28, flywheel 27, and a non-stretching drive belt 22; the latter may pass over an idler roller (not shown) movable to engage and dis-engage the drive.

Abstract: 592,398. Microwave couplings. WESTERN ELECTRIC CO., Inc. Dec. 7, 1943, No. 20478. Convention date, March 26, 1942. [Class 40 (iii)] A wide-band microwave impedance-matching coupling for connecting an unbalanced circuit 5, 6 to a balanced circuit 4 comprises a double wave-guide structure 17, 13, 14. The coaxial line 5, 6 having a grounded outer conductor 6 feeds oscillations from a source 1 to a connecting chamber, 17 through an aerial element.22 formed by an extension of the inner conductor 5. The exposed length of the latter is regulated by means of an adjustable sleeve which thus. constitutes a multi-frequency device for matching the input impedance of the chamber 17 to the characteristic impedance Z /2 of the line 5, 6. The energy then divides through the two halves of chamber 17, each of characteristic impedance Z, into the four legs, each of impedance Z/2, of the loop sections 13, 14 and then passes through the feeders 8, 9, each . of which has an impedance Z /4 so that an impedance Z /2 faces the outgoing balanced line 4. The outgoing feeders are connected to opposite faces of the loops 13, 14, in order that the polarization may be such that the cores 8, 9 are excited in opposite phases with respect to the earthed sheaths 10, 11. The wave-guides 13, 14 may be folded in the plane of their depth, Fig. 2 (not shown), instead of that of their breadth, Fig. 1, and may be so twisted that the feeders 8, 9 have to be connected on the same side of the structure instead of as in Fig. 1. In a further modification, Fig. 3 (not shown), one of the loops 13, 14 may lie over and parallel with the other.
