Filed: 1968-10-10
Abstract: 1278271 Moulding plastic substances ADAMS POWEL EQUIPMENT Ltd 10 June 1969 [10 Oct 1968] 48104/68 Heading B5A [Also in Division B7] In a moulding machine where a stream of end-to-end pallets is fed beneath a hopper to receive a moulding composition and the composition is shaped by the top surface of the pallets and a device such as a roller which overhangs the pallets, a pallet-feed mechanism is provided which comprises drive-elements 5, Fig. 2, mounted on endless driving chains 4 which elements are arranged to produce a continuous and uniform motion of the pallets 3. Such motion is achieved by providing each element 5 with noses 18 which, engage shoulders 27 on a pallet, pivoting the element to the chains 4 as shown in Fig. 4 (not reproduced), providing a follower 19 which engages a track 21, and spacing the drive-elements 5 such that as one element disengages at the left-hand end of track 21 another element engages a pallet when at the right-hand end of the track. The speed of the pallets is somewhat greater than that of chains 4 since track 21 is inclined upwardly, noses 18 being rounded to facilitate angular movement against shoulders 27. Disengagement of elements 5 occurs as followers 19 run on a horizontal track 28 and during the return run of the elements, their operative attitude is maintained by the engagement of a secondary follower (20), Fig. 3 (not shown), with tracks 22 and 23. A cutter mechanism is described which comprises two knives vertically reciprocable between guides 32, Fig. 6, and mounted on a frame 30. Frame 30 is reciprocated horizontally on slides 31 by a rod and crank mechanism, see Fig. 7 (not reproduced), connected to bracket 37, motion in the downstream direction being at the same speed as the pallets.

Title: Sense-write circuit
IPC: G11C11/414
Filed: 1974-11-07
Abstract: 1473243 Sense-write circuit for digital stores  MOTOROLA Inc 7 Nov 1974 [26 Dec 1973] 48236/74 Heading H3T In a sense-write circuit for sensing voltage levels representative of a logical "0" and "1" stored in a digital store 44 or 46, Fig. 2, and for writing voltage levels representative of a logical "0" and "1" into the store, the outputs of first and second amplifiers 84, 88 and 100, 106 are connected to the inputs of first and second driver circuits 92 and 108 and the output of the driver circuits 92 and 108 are connected respectively to the inputs of the amplifiers 100, 106 and 84, 88 and the first and second amplifiers 84, 88 and 100, 106 are coupled to first and second sense-write conductors 48 and 50 for interacting with the digital store 44 to form respective unity gain amplifiers. Reading.-With the storage cell transistors 62 and 66 on and 64, 68 off the base voltage of transistor 84 will be the same as the base of the "on" side transistors 62, 66 and the output voltage V 01  is approximately equal to a row select voltage applied at 59 to row select transistor 54. This portion of the circuit functions in a similar manner as a unity gain amplifier (10, Fig. 1, not shown) where a diode connected transistor (12) is considered to be replaced by the "on" side of the flip-flop storage cell 44 of Fig. 2. The voltage on the base of 84 is coupled via emitter follower 92 to the base of transistor 100 of a differentially connected pair of transistors 68 and 100. The transistor 100 conducts the sense-write line source current I from source 51 through the sense-write conductor 50 to provide an output voltage at V 02 . The storage state of the cell 44 is represented by the differential voltage V 01 -V 02 . Writing.-To change the state of the cell 44, e.g. the base of the transistor 84 is driven more positive than the base of the "on" transistor 66 of the cell 44 by a write "0" input voltage at 98. The circuit operation as a voltage follower ends and a differential transistor pair 66 and 84 is formed. Transistor 84 conducts the sense-write source current I from source 50 through sensewrite conductor 48 and the output V 01  goes low. Transistor 100 now forms a differential pair with off transistor 68 and as the base of 100 falls below the base of 68 it conducts the sense-write line source current I from 51 causing switching of the state of the cell 44. The output voltage V 02  now rises and follows the row selection voltage applied at 59. The sense-write circuit uses a feedback arrangement of the internal differential voltage of a flip-flop storage cell to sense the stored data state. The sense-write amplifier 42 can be coupled to a plurality of columns of RAM cells by additional transistors such as 116, 122 connected to sense-write buses 120, 122. The storage cell 44 includes gating transistor 66 which may be formed in the same isolated epitaxial region as transistor 62 which have common collector and base regions and constitute a double emitter transistor. Sehottky diodes 74, 76 may be included to provide faster circuit operation.

The chain, to which the elements 105 are attached, is supported upon four sprockets 250-253 of which 251 is driven. Sprockets 250 and 253 (Fig. 9, not shown) are mounted upon a frame 262 which is movable in guides 264 by a piston-cylinder 267, such movement being made as to take up any slack in the conveyer loop. To aid in keeping the chain taut and continuously moving, a second continuous chain loop 276 is provided. This has its driven reach in engagement with the driven reach of the first loop but is driven at a slightly faster speed.  The second loop is mounted on two sprockets 277, 278 and its return, or lower, reach glides over a long ball race 285-287.  To ease the movement of the main chain the link pins 257 may have sleeves 274 fitted thereto.  If it is desired to bend a glass sheet along an axis angled to the longitudinal axis of the sheet the conveying element 105 at one end of the sheet may be of a different length from the element 105 at the other end.

The earth return conductor of each chip may be constituted by a metal substrate but preferably, when the wafer is silicon, by an aluminium layer on a silicon substrate, and voltage supply conductors by the requisite number of metal tracks on one or more levels insulated from the aluminium earth conductor and the exterior by glass, barium titanate, sputtered silica or anodic oxide, the dependent contacts extending to the conductors via holes in the insulation. In the arrangement shown in Fig. 7 the chips 6 and replacement chips 2R as described in UK Specification 1,425,283 are face bonded to contacts on the wafer by conventional controlled collapse bonding techniques, the contacts on the chips registering with exposed contact areas on power feeder lines 20 between the columns of ICs and bus conductors 21, both formed by a third metallization layer on the silicon wafer. In order to reduce noise the conductors 21 may be shaped as shown so as not to overlie any lower level signal conductors in the channel. Since the conductor paths on the chips may be thicker, wider and more closely spaced than paths on the wafer itself their use reduces voltage drop in the busses, gives improved decoupling and facilitates pulsed voltage operation. To reduce current crowding at connections between the chip conductors and those on the wafer each connection may comprise a plurality of spaced contacts (Fig. 2, not shown).
