Title: Methods of and circuitry for changing the operating state
IPC: G09G3/28
Filed: 1972-03-24
Abstract: 1385211 Matrix displays FUJITSU Ltd 24 March 1972 [25 March 1971] 13992/72 Heading G5C A method of operating a gas discharge display/  memory panel comprises applying sustain pulses to X, Y conductors of the panel and applying, between sustain pulses V s , first aconditioning pulse V p  to a selected X conductor to cause a discharge and a reversal of the wall charge V Q1  and then a converting pulse V d  to a selected Y conductor to cause a discharge and alter the wall charge to V Q2  sufficiently to prevent subsequent said sustain pulses causing a discharge at the intersection of the selected conductors. The method prevents erasure of half selected cells. The sustain pulses on each conductor may be the same when the wall charge is reduced to zero or of different magnitude when the wall charge is altered. The sustain voltage may include another train of pulses which produce a discharge only with the altered wall charge V Q2 , Fig. 13 (not shown). If the sustain pulse trains have a different frequency a change in brightness is produced which may effectively be erasure. The pulses V s , V p  V d  may be of the same or different height and width. Pulse circuitry including gate circuits, decoders, and address registers is described.

Title: Improvements in or relating to thermo-regulator taps for radiators for central heating
IPC: F16K31/68

Abstract: 442,848. Thermo regulating valves. ROYER, G. G., 31, Boulevard PÚreire, Paris, and SOC. ANON. DES USINES CHAUSSON, 35, Rue Malakoff, AsniÞres, Seine, both in France. May 11, 1934, No. 14332. Void [Abridged as open to inspection under Sect. 91 of the Acts, Nov. 13, 1934]. Application for addition to 424,381. [Class 135] The thermo-regulator tap described in the parent Specification is modified by the provision of a lever 52 pivoted at 53 and resting on the head of the thermostat 58, the end of the lever being engaged by a lever 51 on a spindle 44 carrying an arm 43 connected to the valve 40 of the radiator. The spindle 44 passes through a rubber ring 46 in one wall of the housing 45 which is spaced from the insulating casing 47 by rings 50. The pivot 53 is carried on an arm 54 which may be rotated by a graduated hand wheel 56. To increase the temperature, tho corresponding graduation on the wheel 56 is set opposite the reference mark thus moving the pivot 53 upwardly. This allows the lever 51 to fall, and opens the valve 40 to increase the temperature. The head 57 of the thermostat then rises until the valve is closed after which if any further rise in temperature occurs, a spring 59 allows the head of the thermostat to yield. If the temperature falls, lever 51 drops and the valve 40 again opens to increase the heat supply until the predetermined temperature is reached. To lower the temperature, the hand wheel is again set to the desired temperature thus lowering the pivot 53 and compressing the spring 59. After a time, the valve being closed, the temperature falls and stem 61 descends and relieves the spring 59 until, when the desired temperature is reached, washer 60 engages the ring 62 after which any further fall in temperature causes the head 57 to descend and the valve to be opened to increase the heat supply.

The shafts are supported in bosses 22, 23 at the ends of arms 24, 25 fixed. to rock shafts 11, extending from the shafts 10, the combined shafts 10, 11 being rotatable in a non-rotary casing 16 and stop means being provided to ensure that the discs 26 are always engaged between the annuli 28. As described, the gear operates automatically, its velocity ratio varying with the torque and the discs 26 climbing of their own accord between the annuli for a lower gear ratio on increasing load. The velocity ratio may also be controlled manually; for example, the arms 24 can be connected by pivoted links 38 to a plate 41 and sleeve 42 within which the driven shaft 37 rotates, the sleeve 42 &c. being turned to change the velocity ratio by a hand-operated worm 45 engaging a gear 44 thereon.

Patent GB-824836-A (GB)
Title: A process for the nuclear alkylation of phenols
Filed: 1958-05-06
Abstract: Phenols are alkylated in the nucleus by heating the phenol at a temperature above 150 DEG  C., preferably between 200 DEG  and 275 DEG  C., with a lower saturated aldehyde, a lower primary alcohol, and a base such as an alkali-metal hydroxide or an organic amine, the pressure being such that the reaction takes place in the liquid phase.  Methyl, ethyl or propyl radicals are introduced to the aromatic nucleus by reacting the given phenol with formaldehyde and methanol, or acetaldehyde and ethanol, or propionaldehyde and propanol, respectively.  In certain cases the addition of the aldehyde may be omitted as it is formed in situ from the primary alcohol.  The process may be used to prepare 2,6-di-tertiary-butyl para-cresol from 2,6-di-tert.-butyl phenol.  Other phenols which may be alkylated by the process are: p-cresol, m-cresol, 2,6-xylenol, 2,4-xylenol, 2,6-di-isopropyl phenol, p-isopropyl phenol, and 2,4-di-tert.-butyl phenol.  A catalyst such as copper or copper chromite may be employed in the process.  In Example 1, di-tert.-butyl phenol, formaldehyde, sodium hydroxide and methanol are heated for 1 hour at 225 DEG  C. in a pressure-vessel which contains a piece of copper screen.  Methanol is removed from the reaction-product by distillation, and water is added to it.  The mixture is then extracted with ether.  Ether is distilled from the extract; and the residue is distilled under reduced pressure to yield 2,6-di-tert.-butyl p-cresol.  There is also obtained a small proportion of bis-(2,6-di-tert.-butyl phenol).  Examples 15 to 19 relate to the preparation of 2,6-di-tert.-butyl-4-ethylphenol, 2,6 - di - isopropyl - 4 - methylphenol, 2,4,6-trimethyl phenol, a 1:1 mixture of ortho- and para - cresol, and 2,4 - dimethyl - 6 - tert. - butyl phenol, respectively.  Example 6 relates to the preparation of 2,6-di-tert.-butyl-p-cresol by heating 2,6-di-tert.-butyl phenol with methanol, in the presence of sodium hydroxide and a copper screen, at 250 DEG  C. for 4 hours.  The reaction is attributed to the formation of formaldehyde in situ.

Filed: 1974-04-01
Abstract: 1470716 Gun-loading device BOFORS AB 1 April 1974 [2 April 1973] 14442/74 Heading F3C An artillery piece having a barrel and a loading device comprises a loading table 6 for carrying a number of rounds 7 and mounted in a predetermined position relative to the barrel and having a generally-downwardly-inclined rounds-supporting surface whereby rounds 7 on the table can roll laterally under the control of a feeding mechanism for feeding them one at a time to a transferring means 8, 9 (or 9 onlysee below) operative to transfer rounds to a ramming position at the barrel; the feeding mechanism has two series of stops. As shown, three rounds. Fig. 3, are retained on loading table 6 by two first series of stops 13, each series being secured to a rotatable shaft 12, Fig. 2. When a handle 19 is pulled by a member of the loading crew occupying a seat 20, Fig. 1, the stops 13 are lowered through slots 15 in the table, while simultaneously two second series of stops 14, secured to the same shafts, are raised through further slots 15. In consequence, the lowermost round is permitted to roll into loading trough 8 (see Fig. 4), while the former second and third rounds occupy positions intermediate those formerly occupied by the first, second and third rounds. When the handle 19 is pushed in again, stops 13 are again operative, and a further round may be introduced at the left (compare Fig. 3). Trough 8 when unloaded lies parallel to table 6, Fig. 2, but the introduction of a round causes it to pivot against the force of a spring 28, Fig. 6, about a shaft 27 coaxial with the elevating trunnion 5, Fig. 1; the trough is now parallel to a loading tray 9, Fig. 1, and may be tilted about an axis parallel to its length by manipulation of a handle 22, Fig. 2 (shown also on the left of Fig. 6) by the crewman, to tip the round into tray 9. Tray 9 is then swung on arms 11 pivoted to a beam 11a of the cradle to the ramming position shown dotted in Fig. 1. In Fig. 7 (not shown), trough 8 is omitted, the table is widened to accommodate four rounds, and the remote ends of arms 11a of tray 9 are pivoted on a spring loaded pendulum arm supported for rotation coaxially with trunnion axis 5.
