Title: Method of and apparatus for the production of expanded aminoplasts and modification of the cellular structure thereof
IPC: C08J9/30
Filed: 1965-05-17
Abstract: Foamed aminoplasts are produced and have their cellular structure modified by mixing a water-soluble aminoplast resin and a hardening agent and foaming the mixture so produced directly, before initiating the hardening process, by introducing gas or by agitating, without the use of a foamed-up foaming agent, and during or after the admixing of the reaction components leading to the hardening of the foamed aminoplast resin produced and shortly before injection moulding or extrusion, adding a solution or dry mixture of gas, particularly air, and at least one pulverulent additive continuously to the foamed aminoplast resin being produced, while the latter is in a shaped but not fully hardened condition.  The aminoplasts are water-soluble synthetic resins obtained by the condensation of urea and/or thiourea with formaldehyde in the presence of catalysts and at an elevated temperature.  A foamed-up foaming agent is any known foaming agent in solution or dispersion which has been foamed, for example by beating or stirring.  In the examples are used: aqueous urea-formaldehyde precondensate modified with furfural, phenolformaldehyde resin, asbestos flour, silicic acid-impregnated wood flour, aqueous ortho-phosphoric acid, aqueous urea-formaldehyde precondensate, aluminium sulphate, calcium carbonate, ammonium chloride and gum arabic.

Title: Accumulator circuit
IPC: G06F7/498
Filed: 1966-12-07
Abstract: 1,117,517. Accumulators. INTERNATIONAL BUSINESS MACHINES CORPORATION. 7 Dec., 1966 [30 Dec., 1965], No. 54791/66. Heading G4A. An accumulator comprises a closed-loop shift register, the bits of two multi-bit digits each being entered into a particular stage of the register, during shift-around, when the stage has an order of significance appropriate to the bit, the register having sufficient stages to store a series of bits equalling in number the bits of either digit and a carry bit, means interconnecting some of the stages for effecting counting of the entered bits and carries between the stages. In Fig. 4, two binarycoded-decimal operands to be added or subtracted are read from memory, low order first; in interleaved fashion, viz. one bit of one operand then one bit of the other etc., to a trigger 44 which feeds a circuit 45. Circuit 45 complements the subtrahend if subtraction is required but otherwise passes the operands unchanged via AND gate 33 to a data input line 31 of the closed-loop shift register which consists of triggers CY, P1, P2, P4, P8 adapted to shift in the sequence CY to P8 to P4 to P2 to P1 to CY. Data input line 31 also receives as appropriate the bits of a corrective six, corrective ten, and fugitive one (the last in the " units " decimal order during subtraction) from AND gates 34-37. Eight clock cycles are used for each decimal digit, each cycle ending with a onestage shift in the register. During each of the first four cycles, a respective binary order is dealt with, any data, corrective six and fugitive pulses for that binary order being supplied in turn to line 31 to trigger CY to be counted. The second four cycles are used for addition of corrective ten pulses if appropriate and for supplying the result for the decimal order from trigger CY serially via AND gate 51. During the eighth cycle all' stages of the register except P1 are reset, P1 storing any carry to the next decimal order, then shift occurs to place the carry in trigger CY. Pulses on data input line 31 in a given cycle are effectively counted in the register, but at certain times certain interstage carries are inhibited to prevent incorrect results. Output may also be taken to a printer from the register stages P2, P4, P8, CY in parallel when the carry to the next decimal order is in P1. As a modification, corrective six may be added during the last four cycles rather than the first four, on sensing a sum greater than 9: this dispenses with the need for the corrective ten facility during addition. Radix 12 or 20 may replace radix 10.

In the rotary cylinder and dial machine shown, the two parts 11, 12 of needle cylinder 10 are held together by bolts 15A and form between them a circumferential, recess 17 overhung by a lip 18 on part 11 which also has a circumferential recess 19 overhung by a lip 20. A rabbet 16 is formed in the lower end of part 12 and channels 21 extend from rabbet 16 to beyond lip 20 to receive steel walls 26 to form tricks 32. A rod 25 held in recess 17 passes right round the needle cylinder and forms a pivot for removable rockers 35. Each needle 33 has at least one butt 57 and at its lower end engages rocker 35 which also engages the upper end of a corresponding jack 34 with one control butt 53 and pattern butt or butts e.g. frangible butts. A jack 34 is raised by a cam and through rocker 35 raises corresponding needle 33 to welt position, the needle moving further than the jack. Further cams acting on butts 54 and- 57 of the jack and needle respectively raise the needle to tuck and clearing position. Movement of the needle down to knocking-over position by cams engaging butt 57 push the rocker and jack back to their initial position. The needle and jack cam assemblies comprise cam sections 70A, 70, 70B having cut outs 79, 80 which receive U-shaped inserts 81B, 81C with inner and outer webs 82A, 82B flush with the inner and outer faces of the body 76. Parallel oblique slots are provided in the webs to form guides for selectors 86. A retainer plate 88 adjacent each insert is releasably secured to the support 75 so as to be slidable between first and second positions in which its edge overhangs slots 85 to a greater or lesser degree. When a selector 86 is in its operational position, a shoulder 96 engages outer web 82B and is held in this position by plate 88 in its first position engaging edge 102 on selector 86. With the plate 88 in its second position, selector 86 can be slid outwardly until edge 103 opposite shoulder 96 engages plate 88. Selectors 86 correspond in levels to the jack butts 54. Cam elements 107, 109 on support 75 form cam tracks 108, 110 which control jack butts 53. Cam element 120 on support 75 provides a track for needle butts 57 and the butts of selected needles are engaged by spring biassed clearing bolt cams 122A, B, C whose oblique borders 133 cover the spaces between adjacent cams. Opposing cams 122A, B, C. There are adjustable stitch cams 137A, 137B which engage butts 57 to move the needles to knocking over position regardless of their previous position. Track 121 moves any jacks not moved forward by track 108 so that their corresponding needles are moved to welt position. Track 150 provides any other needle movement necessary.

During recording, capstan 27 rotates at constant speed to form an accumulating loop 39 allowing the pressurized space 15 to form the running loop 40 as space 15 passes the entrance 32 to guides 9. A pulsating loop 37 formed by pressurized air in a mouthpiece 34 assists the loop 40 to leave the surface of drum 4. During each turn of rotor 2, the head 1 records one frame or field on the tape portion held stationary relative to drum 4 by space 16. A magnet 23 rotating with rotor 2 induces pulses in a stationary head 24 which are used to synchronize rotation of head 1 to the frame sync. pulses and are also recorded by a head 31 on a control track of tape 10. During playback, the pulses on this control track are sensed by head 31 to control the speed of capstan 27. A stop frame image can be reproduced if a braking device 33 is actuated, no running loop 40 then being formed. By controlling the brake 33 via signals from head 31 to operate intermittently for periods each less than the period of rotation of head 1 but greater than the time needed for space 15 to pass entrance 32, slow motion reproduction is achieved when capstan 27 rotates at low speed, the running loop 40 then being of the same size or during normal speed transport but being formed less frequently. Speeded-up reproduction is achieved if capstan 27 is rotated at higher than normal speed to give a larger than normal running loop. In alternative forms, Figs. 4, 5 (not shown), two video heads are provided and the rotor is constructed so that two running tape loops are formed for each revolution of the rotor.
