Title: Improvements in or relating to Wave Correcting Circuit Arrangements
IPC: H03K3/013
Filed: 1968-03-07
Abstract: 1,153,268. Wave-shape correction circuit. MARCONI CO. Ltd. 7 March, 1968 [9 March, 1967], No. 11126/68. Heading H3P. A wave-correcting circuit for removing switching transients has two NAND gates coupled together such that the output of one gate is applied to one input of the other gate and has the second input of both gates clamped with pulses applied by respective feedback loops responsive to the output of the adjacent gate. In Fig. 1, the NAND gates 1 and 2 are shown, with the clamping pulses applied to inputs b of both gates by the respective monostable feedback circuits, each containing two additional NAND gates 3, 5 and 4, 6 and an R.C. time-delay circuit. The broken lines of the circuit containing NAND gates 7, 8, 9 show how the part of the input signal that is blocked by the main circuit, could be obtained if required.

Title: Improvements in and relating to locks
IPC: E05B27/08
Filed: 1934-04-13
Abstract: 438,513. Change - key locks. LEJBOWICZ, F. J., 7, ul. Wolnosci, Krolewska Huta, Poland. April 13, 1934, No. 11148. Convention date, April 13, 1933. [Class 44] A locking mechanism operated by a pushkey 2 with adjustable bits 1 has pushers 5 and locking pieces 9 sliding in grooves in inner and outer cylinders 12, 13. The pushers 5 are moved inwards against springs 6, and each has a projecting nose 7 which normally engages in a recess 8 in one of the pieces 9. The pushers 5 and pieces 9 are thus displaced in pairs to positions which vary according to the adjustments of the key bits 1 and the central part 14 of the key engages in the slot 15 so that the central rod 16 can be rotated to fasten the lock. The disc 18 causes the cylinder 13 to rotate with the rod 16 and this disengages the locking pieces 9 from the pushers 5. The pieces 9 are held in place by pegs 20 on the casing which engage in racks on the pieces, and the springs 6 return the pushers 5 to their initial position when the key is withdrawn: The locking mechanism can then only be released by means of a key having the same setting of bits as that used to lock it. The disc 19 may be connected to the bolt of the lock, or may in the case of a padlock act as the bolt. In a modification the inner cylinder provided with the pushers 5 is arranged to rotate and is connected to the bolt. This enables the casing and the central rod to be dispensed with.

R4 and a diode D1. A regenerative feedback loop may be provided via R7. In the absence of input signals at E, E1, E2 diodes D1, D11, D21 are conductive so that T1, T2 are non-conductive, giving a binary 0 at terminal S. When a binary 1 is applied to all terminals E, E1, E2, the diodes become non- conductive so that both T1 and T2 become saturated giving a binary 1 at S. The output at S remains 0 in the event of failure of either of the supplies P or M. The AND circuit Z may be replaced by a conventional OR circuit as in Figs. 5a, 5b (not shown). In Fig. 9 (not shown) one of the inputs E is provided by a diode OR circuit, one input of which is provided by the output of a two-input AND gate (similar to that shown at Z), the two inputs of which are provided by diode OR circuits.

Abstract: 880,537. Filters and coalescers. FAUDI FEINBAU G.m.b.H. April 5, 1960 [April 13, 1959], No. 11947/60. Class 46. In a filter which includes filter layers of different pore size, the pore size of the layer which is to be passed through first by the liquid is approximately fifty to one hundred and fifty times, preferably one hun dred times, greater than the minimum size of the particles to be held back by the filter. Liquid fuel admitted at 3, Fig. 1, to the left of a partition 8 has solids removed from it, and water in it coalesced, by structures 10. Purified fuel is discharged at 7 whilst water drains out at 5 and air or gas released from the fuel is discharged at 6. To dissipate electric charges the housing 1 is earthed, and a partition 8 to which the metallic parts of the structures 10 are effectively connected is also earthed. In Fig. 2, showing one of the structures 10 a filtering layer 12 of resin-bonded mineral fibres is compressed between a pre-stressed wire helix 13 and a perforate metal tube 11, and has pores of a size one hundred times greater than the minimum size of the particles to be held back by the filter. A coalescing layer 14 surrounding the wire helix consists of resin-bonded glass fibres ; it is retained in position by a sheet of burlap 15 wound spirally to form layers and by a perforate metal cylinder 16. The ends are sealed at 19 to annular metal cups 17, 18 respectively. The structure is clamped between annular members 22 and to the partition 8 by spindle means 21, Fig. 1. In Fig. 5, the filter layer 23 consists of resin-impregnated coarse glass fibres ; the layer initially has an outside diameter greater than that of a perforate metal cylinder 25, and is pre-stressed by forcing it in to the latter, using a tapered guide member. The polymerisation of the resin is effected after this step. Surrounding the cylinder 25 is an emulsion-breaking layer 26 of glass fibre, and surrounding this again is a coalescing layer 27 (indicated by a change of direction of shading) also of glass fibre. A layer 28 of onion-bag fabric is included. The required pore size of the filter layer is determined by selection of the diameter of the fibres constituting the layer, by degree of compression of the layer, and by concentration of impregnant.
