Title: Improvements in or relating to apparatus for tracing designs at regularly spaced intervals
IPC: B43L13/24
Filed: 1946-09-02
Abstract: 616,441. Drawing equally spaced lines and curves. DIVAR SOC. ANON. Sept. 2, 1946, Nos. 26354 and 26355. Convention dates, Sept. 7, 1945, and May 6, 1946. [Class 97 (iii)] Apparatus for producing a step-by-step motion in repeating drawings of lines, curves or other designs comprises a guide 1 attached by pins 2 to the drawing surface 3 and a carriage 4 to which is detachably secured the ruler or templet for guiding the drawing instrument, and which slidably engages the guide 1. Pivoted in the carriage 4, about a spindle 10, is an oscillating lever 12 having a pin 24 engaging in a slot 25 of a roller 15 also pivotally mounted in the carriage 4. The travel of the lever 12 is limited by a fixed stop 26 or by a fixed stop 28 co-operating with an adjustable arm 27 which may be locked in the desired portion by knob 29. A slide member 17, of trapezoidal crosssection, slides in a similarly shaped groove 16 of the guide 1 and carries a pillar 19 to which are attached a metallic ribbon 18, whose other end is secured at 20 to the roller 15, and a spring 21 secured at its other end to a stem 22 on the carriage 4. Depression of the lever 12 causes the pin 24 to move in the slot 25, thus rotating the roller 15 in the direction of the arrow 31 at the same time binding the slide member 17 in the groove 16, thereby causing the ribbon 18 to be wound on the roller 15 so that the carriage 4 moves in the direction of the arrow 32. On release of the lever 12, when the pin 24 has reached the bottom of the slot 25, the slide member 17 is released from frictional engagement with the groove 16 and the extended spring 21 pulls this member also in the direction of the arrow 32 until the metal ribbon 18 is again unwound. Pressure may be applied to the end 33 of lever 13 to release the roller to enable the apparatus to be moved in the reverse direction. Adjustment of the distance moved in each step is made by adjusting the position of arm 27. In a modification the slide member 17 is dispensed with, the roller 15 being adapted to engage the groove 16 direct and a metallic wire is used in place of the ribbon 18.

Title: Charge transfer sensing circuits
IPC: G11C11/419
Filed: 1975-06-23
Abstract: 1495063 Transistors capacity storage cells INTERNATIONAL BUSINESS MACHINES CORP 23 June 1975 [23 July 1974] 26502/75 Heading H3T A circuit for sensing information stored in the form of a charge comprises a pair of bit lines responsive to memory cells 21A, 21B and coupled to inputs of a differential sense amplifier 10 which includes a latch 12 and a pair of preamplifiers 14A, 14B, which in co-operation with the capacitances of the bit lines condition the latch to be set to one or other of its two states. Assume a "0" initially stored in cell 20A is to be read out and that "dummy" cells 36A, 36B are charged to a voltage halfway between that corresponding to a "0" and a "1". The circuit is first precharged by applying signals V p , V R  to turn on transistors 24A, 24B, 38A, 38B, charging lines 18A, 18B to a potential determined by V R . The signal V R  is next reduced to zero cutting off 38A, 38B and the charges between capacitors 42A, 44A and 42B, 44B redistribute. V P  is then returned to zero, leaving nodes 16A, 16B prepared. To read out the state of cell 21A V R  is again applied and access lines 15A and 23B are energized. Cell 21A now receives the charge stored at node 16A and cell 36B receives half the charge stored at node 16B resulting in a difference in potential between 16A and 16B so that when a ramp signal is applied at V L11  transistor 28 turns on and transistor 30 remains off. This discharges store 21A back to its original "0" state, whereafter the access signal on line 15A is removed. A signal V RD  turns on 34 to re-equalize nodes 16A, 16B, the continued presence of V R  allowing lines 18A, 18B to return to the "half voltage" value and hence to reset cell 36B to the half voltage value before the access signal or 23B terminates. If cell 21A stores a "1" the potentials on 16A, 16B are such that read out causes 30 to conduct instead of 28 so that cell 21A is not discharged.

Class 68(1). In a toothed blade for heavy earth-moving and road-working equipment, some or all of the teeth are skewed relatively to the plane of the body of the blade. In Figs. 2, 3, the body 10 of the blade is secured by bolts 15 to a mouldboard 8, and the teeth 12 are provided with bevelled undersurfaces 16. The teeth are disposed in planes which intersect the plane of the body 10 at a constant angle, e.g., 45 degrees, and may be cast in this form, or set therein by bending a flat blank. Various effects may be produced by varying the angle at which the mouldboard is dragged over the work. If the mouldboard is disposed at 45 degrees to the direction of motion, the edges 19 will be presented at right angles to the said direction and a full scraping action, with the zones of operations of individual teeth 12 overlapping, will result. If the mouldboard is again disposed at 45 degrees to the said direction, but at an angle of 90 degrees to its previous disposition, only the edges 22 of the teeth 12 will be effective and a scarifying action will result. In the intermediate setting of the mouldboard, i.e., at right angles to the direction of motion, a partial scraping and a partial scarifying will be effected. The teeth may be skewed in the opposite direction, according to whether a right or left-handed blade is required, or, in a modification, successive teeth may be skewed in opposite directions. In addition to being skewed, the teeth 62, as shown in Fig. 22, may be slanted relatively to the body part 60. The blade may be attached to the forward edge of a bucket, in which case the skewing of the teeth gives to the blade an increased vertical dimension which facilitates the entry of the bucket edge into the material penetrated by the teeth.
