Title: Nondestructive Read-Out Storage
IPC: H03K19/00
Filed: 1967-08-08
Abstract: 1,188,338. Non-destructive read-out and read-only stores; adaptive circuits. INTERNATIONAL BUSINESS MACHINES CORP. 8 Aug., 1967 [8 Aug., 1966], No. 36325/67. Headings G4A, G4C and G4R. A non-destructive read-out storage device comprises m storage units each including a plurality of weighting units connected in cascade with each receiving the output of the preceding weighting unit and an n-bit address word supplied to all the storage units, whereby each storage unit implements a predetermined Boolean expression with the n bits of the address word and provides one bit of an m-bit output word, m and n being integers greater than one. In Figs. la, 1b, m blocks 10-1 to 10-m receive an n-bit address in common and provide respective bits of an m-bit output word. Each block 10-1 to 10-m has four threshold devices 11 to 15. Each threshold device 11 to 15 receives as inputs to a summing device 19, the n address bits, the output(s) of the preceding threshold device(s) in the block (if any), and a bias input 17, all through respective adjustable weighting resistors 16, 18 &c. The summing device 19 feeds a threshold circuit 20 which provides the output of the threshold device which goes to succeeding threshold devices in the block except in the case of the last device which provides the respective bit of the m-bit output word. In a second embodiment, a core matrix store (or a card capacitor read-only store as in Specification 1,078,244) replaces the weighted resistors of each threshold device 11 to 15, the signal previously feeding a resistor now, if equal to 1, reading out a corresponding row of the store into an accumulator respective to the block 10-1 or &c. The following operation occurs in all blocks concurrently. Each store is taken in turn, each row of it being read out or not in turn to the accumulator as stated. The accumulator output, after each store has been dealt with, sets a latch if positive to provide an extra 1 input to the succeeding stores in the block, and the accumulator is reset to 0. The contribution of the block to the m-bit output word is 1 if the accumulator output is positive after the last store has been dealt with. Alternatively, a separate accumulator could be provided for each store enabling them to be dealt with together. In this case each accumulator (except the last) in a given block would feed the next accumulator in the block. The weights (of the adjustable resistors or as set in the core or capacitor stores) may be predetermined adaptively as in Specification 1,066,280 or algorithmically.

Filed: 1969-07-18
Abstract: 1,268,119. Armament fire control systems. SOC. EUROPEENNE DE TELEGUIDAGE. 18 July, 1969 [19 July, 1968], No. 36338/69. Heading G4G. An anti-aircraft fire-control system includes an acquisition radar and information-processing means for calculating and comparing: two quantities viz. "time to burst" E of a missile and "time to last decision" T which is the line from the present instant to that beyond which the missile can no longer hit a selected target. The "time to burst" of a missile is the sum of its flight time T 1  from pad to target and the reaction time T 2  of the system. For a selected target having a velocity V(t) and a range D(t), the "time to burst" at an instant t is: where M is the mean velocity of the missile. This quantity is always higher than G, the minimum time to burst of the missile. The "time to last decision" T is defined by The quantities D and V, derived from the radar, and the quantities M and T 2 , which are system constants, are in pulse form and are fed as shown to multiplier 10 and address 20, 21 to form the quantities -(D+T 2 M) and -(V+M), the negative signs arising because of inversion in the amplifiers. These signals and their inverses generated in inverters 30, 31) are fed respectively to the Y terminals of time-division multiplier 40 and to the Z terminals and Y terminals respectively of time-division multipliers 40, 41. A signal representing 1/F, where F is the maximum time to burst, is fed to the X terminal of multiplier 40 and a signal representing generated in divider 11 and adder 22, is fed to the X terminal of multiplier 41. The multipliers 40, 41 perform the operation XY/Z, the output signals respectively representing E/F and T/F. These outputs are fed to pulse-position modulators and symbol generators (Fig. 3, not shown) and, finally, to a PPI 'scope where they appear respectively as circles and triangles (Fig. 4, not shown) in a display having co-ordinates representing time and azimuth. The azimuth signal is derived directly from the radar. The radius of the 'scope represents the maximum time to burst and the decision to fire different missiles is based upon the relative positions of the symbols and their distance from the centre.

Abstract: 449,186. Spectacle lenses. TENNANT, W. J., 111, Hatton Garden, London.- (American Optical Co. ; Southbridge, Massachusetts, U.S.A.) Dec. 21, 1934, No. 36739. [Class 97 (i)] A spectacle lens providing correction for ordinary refractiye errors, and also providing for a change in magnification without change of focus to correct " size error " of the optical image consists of two coaxial components which in combination correct both forms of error, although neither of the components is designed to correct only one of the errors, the two components being fitted and secured together adjacent their peripheries to produce a unitary lens structure. The lens shown in Fig. II has two components 1, 2 separated by an annular spacer member 11 of soft glass &c. so as to provide four refractive surfaces. The components, with the spacer, are mounted between rotating supports 5, 6 and a blowpipe flame 9 is applied to the edges so that they are fused together. The spacer member may extend over the whole space between the lens components. In a modification, the inner surfaces of the components have the same curvature and are placed in contact so that the composite lens has only two refractive surfaces. In another modification in which the inner surfaces are dissimilar and enclose an air space, the edges of the lenses are so shaped that they will butt together. Specification 412,081 is referred to.

Abstract: 993,929. Transverse-flow blowers. T. HELMBOLD. Sept. 20, 1963 [Sept. 20, 1962], No. 37168/63. Heading F1C. In a transverse-flow blower with a drumshaped rotor, a separator is provided between the intake and outlet ducts and in the vicinity of a standing vortex which forms during operation of the blower; the separator, in a direction substantially parallel to the rotor axis and against the direction of rotation of the rotor, terminates in a sharp edge, the sharp edge being disposed in the zone of the perpendicular from the rotor axis to that surface of the separator which faces the rotor. In the transverse-flow blower shown in Fig. 2, the inlet 2 is separated from the outlet 3 by a flat baffle 4 having a sharp edge 5 disposed in the region of a perpendicular 6 from the rotor axis 7 to the baffle. During operation, the usual vortex 8 forms, and the sharp edge 5 has a peeling action to separate the main flow from the vortex flow. To assist the action of the sharp edge 5, the rotor blades may have sharp edges, at least at the outer periphery of the blading. The clearance between the baffle 4 and the rotor periphery may be adjustable. A trough-shaped guide member 9, which may be adjustable, may be provided to stabilize the position of the vortex 8. If the flow through the outlet 3 is required to be other than parallel to the baffle 4, a deflector 11 set at the required angle is provided. This angle and the distance between the deflector 11 and the sharp edge 5 may both be variable. The distance must be sufficient to prevent a return flow into the inlet 2. The deflector 11 may be curved so as to merge into the baffle 4. As shown, the rotor 1 may have end plates 10 projecting radially beyond the outer periphery of the rotor blading to prevent air from flowing into the ends of the vortex 8. Guide plates 12 carried by the baffle 4 at a small distance from the end plates 10 may be provided to prevent air from flowing laterally around the baffle. The guide plates 12 may have curved portions which merge into the baffle 4 and may be integral with the latter. As shown in Fig. 6, the sharp edge 5 may be curved in the plane of the baffle 4. Instead of being flat, the baffle 4 may be curved so that its distance from the lateral parts of the rotor 1 is greater than its distance from the middle part thereof.

Filed: 1974-08-27
Abstract: 1476496 Catches; stays STABILUS GmbH 27 Aug 1974 [8 Sept 1973] 37400/74 Headings E2A and E2F [Also in Division F2] A piston-cylinder gas spring for moving a door or flap (not shown) is automatically locked in a certain position by the mechanical latching of components on the piston rod and on the cylinder. The spring may be locked in a contracted position (not shown) or an extended position. The latching components may be outside (not shown) or inside the cylinder. The locking may be frictional (Fig. 1) or positive-lock (Figs. 2 and 3). In the embodiment of Fig. 1, the piston rod 7 carries a bush 1 with a conical surface 2 and an annular groove 3. The cylinder 6 has a sleeve 9 provided with a recess 4 carrying a spring ring 5. On extension of the spring to open the attached door or flap the spring ring 5 is gradually lifted up by and pushed over the cone 2 until it snaps into the annular groove 3 and locks the spring. Unlocking is effected by enough downward pressure on the piston rod to push the ring 5 back out of the annular groove 3. In the embodiment of Figs. 2 and 3, the piston rod carries an axially fixed but rotatable cam drum 11 bearing cams 12. The cylinder carries a fixed cam sleeve 14 with cam surfaces 15 and detents 16, and a fixed cam ring 17 with cam surfaces 18. On extension of the spring, as the piston rod passes up through the sleeve 14 and the ring 17, the cam drum 11 is rotated by the interaction of its cams 12 firstly with the cam surfaces 15 and then with the cam surfaces 18. On slight contraction the cams therefore are caught by the detents 16, to lock the spring. Unlocking is effected by a slight extension of the spring, the cam surfaces 18 rotating the cam drum a bit more to free the cams 12 from the detents 16 and allow contraction of the spring. The drum may be fixed, and the sleeve and the ring rotatable.

Abstract: 1518164 Ion exchange L & C STEINMULLER GmbH 12 Sept 1975 [23 Jan 1975] 37623/75 Heading B1J Slit-like orifices in the inlets and outlets of a continuous ion-exchanger are cleaned by bringing about a sudden reversal of flow. As described, liquid to be treated flows through the bed from 1 to 6 and out via valve 14, while exchanger is continuously removed at 10, regenerated and reintroduced at 11 under pressure from pump 12. To clean the slits at 3 and 5, valve 14 is closed while pump 12 continues to operate; the increased pressure compresses air 15 above liquid in the reservoir connected through pipe 16; valve 18 is then opened and the pressure in 15 drives liquid through the slits in the reverse direction, cleaning them. Valve 18 then closes, valve 14 opens and normal operation is resumed.
