Abstract: 859,147. Hot water boilers. VORKAUF, H. June 20, 1957 [June 21, 1956,], No. 19492/57. Class 64(1) For use in a heating system including a water-circulation pump, a boiler having a rectangular tubular framework with vertical unheated downcomer tubes in corners thereof has a group of heated riser tubes 10 lining each side wall of a combustion chamber and groups of heated riser tubes 4, 5 lining the two partitions 24, 25 (indicated only in Fig. 5) which form the rear wall of the chamber and define a downtake flue 17. The roof of the combustion chamber is lined with bent-over portions of riser tubes. In Fig. 1, in front of a transverse, main collecting header 6, the side wall tubes 10 lead up from two side headers 2 and bend over to meet a single header 3 at the middle of the top of the boiler. As indicated by bends 10c, formed adjacent the median plane containing the header 3, the six pairs of tubes 10 nearest the front form lower arches to protect the front wall of the boiler. Behind the header 6, the rear wall tubes 5 bend over to line the roof while side headers 14 intercommunicate between the ends of the header 6 and downcomers 1'5 and may communicate with rear downcomers 1 to which they are connected. The rear wall tubes 4, 5 extend between a bottom transverse header 11 and the main header 6 which has an outlet 19 returning the water to the heating system. In Fig. 4 the side tubes 10 cross at the top and meet two top side headers 3a. In the embodiments of Figs. 1 and 4, water returned from the heating system is passed by a header 8, Fig. 1, through preheating coils 7 in an uptake flue, to a header 9 and then by way of the corner downcomers 1 to the bottom headers 2. In Fig. 5, only the rear tubes 4, 5 bend over the top of the combustion chamber and they meet a transverse header 13 which interconnects front downcomers 16 as in Fig. 1, but in this embodiment there is an outlet 31 from the header 13 which returns the water to the heating system. There are also preheaters 7a in an uptake flue which contains riser tubes extending from headers 28, 30 to a header 27. Specification 783,695 is referred to.

Title: Improvements relating to receiving systems for modulated electric pulses
IPC: H04J3/04
Filed: 1945-08-03
Abstract: 638,346. Multiplex radio pulse signaling. STANDARD TELEPHONES & CABLES, Ltd. Aug. 3, 1945, No. 20075. Convention date, Aug. 7, 1944. [Class 40 (v)] In a multi-channel, time-modulated pulse communicating system, in which the pulses are transmitted as an interleaved single train and the pulses of one channel are modified to serve as synchronizing pulses, the receiving arrangement comprises means for segregating the received trains of pulses, each of which is mixed with a corresponding train of bench mark pulses and then applied to a device which translates into amplitude modulation, the time displacement of the channel pulses with respect to the bench mark pulses. The Specification describes a multi-channel system similar to that described in Specification 638,345, but with demodulation carried out in a manner similar to that described in Specification 600,291. Fig. 1 shows a receiving terminal used in the system. The signals received over line 4, or from receiver 7 are passed through clipper amplifier 8 to synchronizing pulse selector 11, which applies the synchronizing pulse train to delay network 13. For each channel, a train of appropriately delayed output pulses from delay network 13 is applied, together with the interleaved pulse train from amplifier 8, to channel selector 21, which provides a single modulated pulse train for application to demodulator 26. The input to demodulator 26 also includes pulses from synchronizing pulse selector 11, which serve as bench mark pulses. The demodulation circuit is shown in Fig. 3. The input, consisting of bench mark pulses and a time modulated pulse train is applied to grid 29 which results in tuned circuit 32 being shock excited. The tuned circuit 32 is tuned to a harmonic of the cadence frequency and the circuit is arranged so that the modulated pulses appear on a linear portion of the oscillating waveform, a clipping arrangement being provided so that time modulation relative to the bench mark pulse may be converted to amplitude variation. A modification is described wherein the synchronizing pulses applied as bench mark pulses to demodulator 26 may be delayed through delay network 13 so that they occur at some desired position relative to the selected channel pulses.

Title: Improvements in or relating to ion exchange resin regeneration
Inventor: PLATZER ROGER
IPC: B01J49/00
Filed: 1960-06-08
Abstract: <PICT:0949832/C3/1> In a continuous process for regenerating ion-exchange resins, the resin passes in cocurrent or counter-current with a regenerating solution and flows as a thin compact layer close to the surface of an electrode.  The regenerated resin is then re-cycled to the ion-extraction stage as a continuous process.  In a suitable apparatus, the charged ionic resin enters the top of a regenerating column at 8 and flows downwards through a rising column of regenerating solution entering at 7, and then past an inclined screened electrode mounted as a frustrum of a cone 2 surrounding the column.  A double cone 13 mounted centrally opposite the electrode presents an angle to the descending resin particles equal to the "angle of rest" of the particles which flow past the electrode in a slowly moving thin stream. Gases generated at the electrode 2 pass out through a vent 10a, and the output of treated resin at outlet 9 is governed by an adjustable restriction 4, and the upwardly circulating regenerating solution cycled by a pump 12.  The regenerated resin is recycled to the extraction stage, and the used regenerating solution flows out at 6.  In an alternative form of apparatus, the resin is fed between two bands of porous cloth as a mono-granular layer, and the double cloth slides at an inclined angle against a perforated plate electrode supported on a series of baffles in the form of sheets of P.V.C. or like material thus forming in the lower part of the casing a series of compact mats through which the regenerating solution flows in counter-current or co-current with the double cloth bearing the resins immersed in it.  Specification 838,262 is referred to.

Patent GB-203082-A (GB)
Abstract: 203,082. Pollak, J. E., (Adlerwerke vorm. H. Kleyer Akt.-Ges.). June 12, 1922. Adding-apparatus; differential mechanism; connections to typewriters.-In a machine for use with a superposed typewriter, a numeral key 1 of the latter, when depressed, displaces a correspond. ing slide 8 so that one of a series of pivoted stops 12 is positioned in the path of a projection 10 on the actuating rack-bar 9 simultaneously released under the control of the typewriter carriage 30. The rack-bar is thus differentially set and remains so until at the end of the setting of the complete item an operating lever 36 is moved to effect the actuation of the totalizing-counter 14 and the restoration of the rack-bars. The lever 2 when rocked by the numeral key thrusts rearwardly a bar 6 provided with a cam rail to displace longitudinally one of the slides 8, of which there are nine arranged transversely. Each slide controls a series of weighted pivoted stops 12 which, when displaced by the slide, move into the paths of the lugs 10 on rack-bars 9. The stop, when engaged by the lug, is held in its displaced position by friction and does not return when the slide is restored by removal of the finger from the key. The abovementioned movement of the bar 6 also, through an universal pivoted plate 34, rocks a bell-crank lever 24 mounted on the sliding carriage 23 moved step-by-step by the typewriter carriage 30 through rack and pinion 27, 26. According to the denominational position of the carriage 23 therefore, one of a series of bell cranks 22 is rocked by the bell-crank lever 24 to remove a locking arm 19 from the lug 20 on the corresponding rack-bar 9, which is thus free to slide rearwardly under spring action until lug 10 meets the displaced stop 12. When the complete item has thus 'been set up, the operating lever 36 is manually pulled forward and through rack and pinion and swinging bail 50 restores the racks and so actuates the counter.
