Title: Improvements relating to priority circuits
IPC: G06F13/14
Filed: 1970-01-29
Abstract: 1,249,762. Priority circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 29 Jan., 1970 [1 Feb., 1969], No. 4357/70. Heading G4A. A priority circuit has the interrogating lines arranged in groups. Interrogating signals are forwarded from each group in turn, all the signals from the lines in any one group being forwarded in the order of their priority before the signals on the lines in the next group are dealt with. This arrangement avoids excessive waiting times for low priority signals. The circuit may control the connections between a computer and its peripherals. In the embodiment shown in Fig. 1, there are three stages G 1 -G 3  each including three interrogation lines G n1 -G n3  (n= 1, 2 or 3). The lines are connected to priority circuits, e.g. in stage G 1  the lines G 11 -G 13  are connected as shown to AND gates 11-14 and to inverters 11a-13a so that a signal on G 11  has priority over one on G 12 , G 12  having priority over G 13 . Gates 11-14 are enabled by a signal Z 3  received from a bi-stable associated with the preceding stage (in this case G 3 ) in the cycle G 1 , G 2 , G 3 , G 1 . . . . Gates 11-14 feed bi-stables FF 11 -FF 14 . A further bi-stable FF 15  is set by a signal Z 2  from bi-stable FF 24  associated with the succeeding stage G 2 . An output from any bi-stable resets the remaining bi-stable in the stage. In operation, when stage G 1  is enabled by Z 3  signals on G 11 -G 13  are forwarded to outputs U 11 -U 13  in order of priority. If a signal arrives on a line when a lower priority signal in the same stage is being forwarded the lower priority signal is interrupted by the higher. When there is no signal on any line G 11 -G 13  gate 14 sets bistable FF 14 , so enabling the next stage G 2  by Z 1 . Signal Z 1  also sets FF 35  of the preceding stage G 3 . This action resets FF 34  so that Z 3  ceases and consequently stage G 1  can no longer forward interrogation signals. Interrogation signals at stage G 2  are now forwarded in priority order. This operation continues for each stage in turn in cyclic sequence. The gates and bi-stables may be replaced by NAND gates, Figs. 3, 4 (not shown).

Abstract: 949,127. Toys. MARVIN I. GLASS, [trading as MARVIN GLASS ASSOCIATES]. Feb. 5, 1962, No. 4421/62. Heading A6S. A doll comprises a head with flexible lips and a rigid tubular member engaging the mouth at one end and at the other end engaging with an expansible chamber, means to expand the chamber with passage of air through an opening in the mouth and to move the tubular member to project the lips and a noise-maker operated by the passage of air. Two members 27, 29 have interfitting concave upper portions which together form the expansible chamber. The concave portion of the member 29 comprises a flexible disc with a central aperture aligned with the tube 103 which terminates behind and actuates the flexible mouth. A sound maker 33 comprising two apertured interengaging dish-shaped members seats against a shoulder in the tube 103. The member 27 has a positioning stud 79 which passes through an aperture in a frame 51 which is secured by a bar 53 to a lug beneath the nose. The stud is fitted with a shock-absorbing pad. A retaining means 83 on the end of the stud is anchored in the frame. The hub portion 69 of the member 27 seats in sockets in the member 29 and frame 51, which are urged together by a spring. A trigger 127 passes through the members 27, 29 and bar 51 and has lugs which engage on opposite sides of and between the members. A lug extending from the bottom of the trigger contacts a spring extending between the frame and member 29. By raising one or both arms, a link 121 joining the arms and passing in grooves 65, 119 in the ends of the frame and member 29, pivots the member 29 and causes the tube 103 to press behind the lips to project them and to partially separate the concave surfaces to cause air to pass through the sound maker 33 and produce the first part of a kissing sound. The trigger allows a certain amount of lost movement before the members 27, 29 pivot together then the cammed end of the trigger engages the frame 51 disengaging a lug from the member 27 and freeing it to spring into contact with the frame 51. The concave members separate producing the second part of a kissing sound. When the arms are lowered, the spring restores the members to their original contacting position. The concave portion of the member 27 may be incorporated in the frame if the spacing of the lugs is such that movement of the member 29 is adequate to separate the two concave members.

Title: Desulphurisation of industrial gases
IPC: C10K1/20
Filed: 1954-02-16
Abstract: Industrial gases containing sulphur compounds, particularly organic sulphur compounds, are purified by passing them over a lead oxide catalyst at a temperature between 180-250 DEG  C.  Lead monoxide is preferred and it may be employed in the form of a powder or granules, combined if desired with inert material.  The process is particularly suitable for gases consisting largely of CO2 and in an example a gas containing 98.8 per cent CO2 and 5 mg/m3 of organic sulphur compounds is treated at 230 DEG  C. and under a pressure of 160 atmospheres. The organic sulphur compounds were completely removed.  In the purification of gases containing hydrogen and oxygen it is found that the oxygen content of the gases is reduced during the purification.

Filed: 1926-02-17
Abstract: 248,729. Pollak, F. March 3, 1925, [Convention date]. Urea-aldehyde condensation products.-Hydrophobe condensation products of urea or its derivatives with formaldehyde are produced by adding organic substances capable of forming resinous products with the formaldehyde in an acid medium to the condensation products resulting from a short heating of the starting materials, and then heating the mixture in the presence of hydrogen ions; the resin precipitates on cooling and the water can be drawn off. Prior to cooling, the reaction mixture may be neutralized or made slightly alkaline. Specified organic substances are thiourea, phenol, or even the urea starting material itself. In addition to substances yielding hydrogen ions, others having a polymerizing action may be added, provided that they do not split off hydroxyl ions, e.g. calcium thiocyanate. The hydrophobe resin obtained may be hardened in known manner, and prior to hardening, it: can be mixed with organic or inorganic substances which may be in the colloidal, powdery or fibrous form. The resinous products are suitable for insulating purposes and for the production of colddrying lacquers. Examples are given of the production of condensation products from urea and formaldehyde in which stated amounts of thiourea, urea and phenol are added, together with formic acid. after ten minutes' heating, the mixture further heated under a reflux condenser for 1-1¢hours, and then cooled after the addition of caustic alkali.
