Title: Mos data storage arrangements
IPC: G11C11/408
Filed: 1972-07-11
Abstract: 1388425 MOS data store SIEMENS AG 11 July 1972 [22 July 1971] 32301/72 Headings G4C and G4H An MOS data store comprises an array of storage cells (not shown), and an address decoding network formed on a single integrated circuit chip, the decoding network comprising address input lines AO-AN, signal inverters JV producing negated address signals Ao-An in response to the trailing edge of a control pulse P, groups DTo-DTm of field effect transistors MD connected in parallel between a respective row or column drive line of the store Xo-Xm and a common point PV, the gates of the transistors MD being connected to combinations of the true and negated address signals such that for each combination of address signals all the transistors MD in only one group DTo-DTm thereof are blocked, a precharge transistor LM for each store drive line to charge the lines during the pulse P, and a delay element supplied with the pulse P and arranged to delay only the trailing edge of the pulse, the delay output being connected to the common point PV. The arrangement gives the inverted address signals formed at the trailing edge of pulse P time to stabilize before the decoders are actuated by the delayed trailing edge of pulse P to prevent spurious drive line selections.  In response to the pulse P transistors LM and LMI conduct to charge the store drive lines Xo-Xm, and the negated address lines Ao-An to the supply voltage Vdd. Address signals are applied to inputs Ao-An and at the trailing edge of pulse P the inverters JT produce the correct address pattern on the lines Ao-An and Ao-An. Each pattern of address signals blocks all the transistors MD of one group DTo-DTm only, so that when the delayed trailing edge PV of the pulse P occurs all the store drive lines Xo-Xm except one discharge via transistors MD. A delay element of FET transistors is illustrated in Fig. 2 (not shown).

Title: New phosphorus compounds, their methods of preparation and their use in fireproofing
Inventor: BILGER XAVIER FRANCOIS
IPC: C01B21/098
Filed: 1957-07-26
Abstract: Polymeric phosphonitrilic chlorides having a formula:-<FORM:0865396/III/1> are prepared by reacting PCl5 with anhydrous NH3 or NH4Cl at above 100 DEG C. wherein there is less than 1 mole NH3 or NH4Cl for each mole PCl5.  The reactants may be refluxed at 125-160 DEG C. in an organic solvent, e.g. tetrachlorethane or carbon tetrachloride.  PCl3 may be used, which is first converted to PCl5 by the action of Cl2 in an organic solvent. Where NH3 is used, it may be injected into the solvent, containing HCl, resulting from the process, forming NH4Cl, which is returned to the process. The phosphonitrilic chloride is completely, or partially, aminated by reacting with anhydrous NH3 at below 30 DEG C., preferably in an organic solvent, e.g. carbon tetrachloride, tetrachlorethane, chlorobenzene or orthodichlorobenzene, when the product precipitates, and may be removed by filtering.  The aminated polymeric phosphonitrilic chlorides are dissolved in water by heating to 60-100 DEG C., and the resulting aqueous solution, which may also include other fire proofing, softening, fungicide, waterproofing or buffer agents, are used for fireproofing fibrous materials, e.g. cellulosic, animal or synthetic textiles, wood, paper or leather. The fibrous material is treated by soaking, foularding or spraying, is dried and heated to above 100 DEG C. in air.  In examples the aqueous solution of an aminated polymeric phosphonitrilic chloride containing hexamethylene tetramine or a buffer mixture of urea, sodium formate and formic acid is used to fireproof cotton twill (7), (8), viscose or viscose staple (9) and the treated fabrics are dried and heated to 140-160 DEG C. Specification 774,694 is referred to.

Title: Improvements in draught-excluding attachments
IPC: E06B7/20
Filed: 1945-12-06
Abstract: 598,523. Draught excluders. DAVIDSON, H. E. Dec. 6, 1945, Nos. 33070/45 and 14296/46. [Class 20(iii)] In a draught excluder for a door which is raised clear of the floor when the door is open and slid downward in a plane parallel to the door to engage the sill when the door is closed and is actuated by a tappet engaging the doorjamb, a spring reacting on a fixed part of the attachment serves both to urge the tappet outwards and the excluded member to its raised position, and also yields if the tappet moves further inwards after the downward movement of the excluded member has been arrested. As shown, a T-shaped lever 14, 15 is pivoted to the excluded body 3 at 17 and supports the excluded member 5 by engaging the stirrup 12. A tube 19, integral with the arm 15, has a circumferential indentation 20 forming an abutment for the nut 21 which slides in the tube. The partially screw-threaded tappet 22, 23 engages in the nut 21 and may have a cap nut 25 at one end to abut the door jamb, and an adjusting head 30 at the other. A helical spacing 29 surrounds the tappet and abuts at one end the nut 21 and at the other a flange 28 of a spring box 26 attached to the body. When the tappet and nut 21 are pushed inwards by the door jamb, the lever 14, 15 is allowed to pivot and drop the member 5, this tappet movement may continue when the movement of the member 5 has been arrested. In a modification the nut 21 is rigid with the lever 15 and a helical spring engaged in the nut acts both as compression spring and tappet end, or the tappet end may be a rigid rod, and the pivot bearing 17 is enlarged to provide a lost-motion device.

Abstract: 429,435. Date indicators. ELBERG, B., 19, Rue Roger, Paris. Nov. 27, 1933, No. 33083. [Class 106 (iv)] A date-indicator comprises clock-driven members for displaying the units and tens of the date figure and so interconnected by transfer mechanism that, if not adjusted, they will indicate consecutive numbers from " 0 " to " 39." In one form, Fig. 1, the clock drives a shaft 10 geared to a one-toothed wheel 4 engaging a pinion 12 having alternate long and short teeth and meshing with a pinion 14 driving the units drum 15. Another onetoothed wheel 17 is secured to the shaft 6 of the units drum and is connected by a pinion 19 to the tens drum 21. A day-name drum 23 is driven from the shaft 10 through similar mechanism. The month-name drum 33 is manually actuated by a knob 35. In another embodiment, Figs. 4 and 5, the indicating drums are mounted on a common axis and are adjusted by knurled wheels 68, 69, 70, 71, the date figure and day-name drums being actuated in a manner similar to that shown in Fig. 1. A shaft 39, driven from the clock through one revolution in thirty-one days, is manually adjusted at the beginning of the month until the number of days in the month is indicated on a scale 51 by a pointer 50 secured to the shaft. The shaft 39 is connected by gearing 42 .. 45 to a disc 46 having a pin 47 which, at the end of the month rocks a shutter 38 to cover the date aperture At the same time a spring 52 brakes a drum 53 and stops the clock. In other forms, the date figures may be displayed on discs and the month names on discs, bands or separate cards. To reduce the time during which the date is being changed, the pinion 12, Fig. 1, may be driven faster and may drive another wheel 4 connected to another pinion gearing with the units drum. In a further modification, Fig. 24, the changing- time is reduced by driving the wheel 4 by a star wheel 95 which is turned by pins on a clock-driven disc 96 and is given a rapid movement during the latter part of each actuation by a spring 97.

Abstract: 1378203 Valves TELDIX GmbH 14 July 1972 [14 July 1971] 33137/72 Headings F2F and F2V An electromagnetic valve arrangement, for use as an anti-skid device which lowers the braking pressure as a result of slip signals, comprises a first armature 3 movable between a first position in which the passageway between pressure inlet 7 and pressure outlet 8 is open, as shown, to a second position in which the passage is closed, and a second armature 4 movable between a first position in which it permits relatively unhindered flow through the passage and a second position in which it permits a reduced flow through a restriction 15 such that on energization of the solenoid 2 both armatures move from their first to second positions but on de-energization of the solenoid the first armature moves back to its first position whereas the second armature is held by fluid pressure in its second position against a spring 6 until the pressure at the inlet reaches a predetermined low level. In the embodiment the passageway 7, 8 connects the master cylinder to the wheel brake cylinder. When the master cylinder is cut-off the brake cylinder is connected to a return conduit via passage 9 so that pressure in the brake cylinder drops and the wheel re-accelerates, thereby terminating the energization of the solenoid. Pressure is reintroduced but at a reduced level until the force of the spring 6 exceeds the force exerted on the second armature by the braking fluid (generally when the brake pedal is released) so that the second armature moves back to its first position.
