Title: Process for correction of the chemical-physical equilibrium in bicarbonate-containing service water in hot-water plants
IPC: C02F1/46
Filed: 1934-08-20
Abstract: 427,766. Electrolytic treatment of water. GULDAGER, A., 201, Jagtvej, Copenhagen. Aug. 20, 1934, No. 24024. [Class 41] To prevent clogging of the pipes in a hotwater plant, the water, containing bi-carbonate such as those of magnesium and calcium, is subjected to slight electrolytic treatment at low voltage whereby the hardness is slightly reduced and the content of free carbonic acid increased ; a thin layer only of scale is initially deposited in the pipes and does not increase. The voltage employed may be 1À5-30 and the current may only amount to 10-25 per cent of that necessary for depositing 30 per cent of the bicarbonate present. The current may be adjusted once for all in relation to the average composition and rate of flow. A small proportion of the hardness producers is precipitated by the current in the form of a loose sludge which collects at the bottom of the container. The electrolytic treatment may be applied before or after passage of the water through the heating chamber, but is preferably applied in the heating chamber itself.
Patent GB-391868-A (GB)
Title: Improvements relating to rubber or rubber-like compositions and articles manufactured therefrom
Filed: 1931-11-05
Abstract: Hollow rubber articles such as shoes are made by pouring a sensitive mixture containing an aqueous dispersion of rubber into moulds comprising a shell and core, and maintaining the outer shell at a temperature which causes gelling of the mix, while leaving the core unheated, removing the article from the mould, drying on a former, and vulcanizing.  The degree of shrinkage is controlled by the size of the former on which the article is dried.  Thus shoes of three sizes may be made by the use of lasts of three sizes on which are placed articles formed in one mould. Concentrated dispersions are preferably employed, particularly those made according to Specification 391,511.  Differential heating as described in Specification 392,497 may be employed. After vulcanizing, the surface may be swelled by treatment with p  rubber enamel, or a solvent, and finished by cold vulcanization.

Abstract: 858,465. Endless conveyers. ATKRON Inc. July 28, 1958, No. 24235/58. Class 78 (1). [Also in Group XXXV] In a conveyer for cans wherein the cans C are fed by an endless belt 10 on which the cans have their axes parallel to the belt 10 but are arranged indiscriminately with either open or closed ends leading, the cans are turned while being conveyed by a further endless belt 22 to a position at right-angles to their former direction in such a way that all their open ends point the same way by a combination of a magnetic drum 23 around which the belt 22 passes, and a pair of air jets 42, 43 located one in front of and one behind the axis of the drum 23. The drum 23 comprises a pair of non-magnetic end castings 30, 31 between which are arranged two annular polepieces 34, 35 and a non-magnetic shell 38 containing a number of permanent bar magnets 37 having their north poles N in engagement with polepiece 34 and their south poles S in engagement with polepiece 35. The cans are transferred from the belt 10 to the belt 22 by a pair of endless belts 15 of segmented construction supported on a plate 16 and travelling at a slower speed than the belt 22 so that the cans are spaced on the belt 22. The belts 14 are arranged to deposit the cans to one side of belt 22 where they are retained by a magnet 29 below the belt so as to be in line with one of the polepieces of drum 23. Upon reaching the drum 23 the transverse magnetic field causes the cans to pivot about their closed ends whether this is in front or behind and present their open ends laterally towards the opposite side of the belt, being assisted in this pivoting by one or other of the air jets 42, 43 according to whether the open or closed end of a can is pointing forwards, respectively. After being thus orientated, the cans pass around the drum 23 and are received in a delivery channel 45 where they are propelled away from the drum 23 by the lower run of belt 23. In a modification (not shown), the drum 23 is replaced by a stainless steel rotating cylinder within which arcuate stationary polepieces and transverse magnets are arranged, so that the magnetic field is restricted to the turning area.

Abstract: 390,527. Converting; protective cutout systems. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Sept. 2, 1931, No. 24681. Convention date, Sept. 2, 1930. [Class 38 (ii).] In an arrangement for supplying a threephase load circuit 3 from a D.C. source 1 through a grid-controlled mercury arc device 26 in which protection against excess current is afforded by including a valve 37 in the connection to the star point of the primary winding 25 of the main transformer, a condenser 5 being adapted to be switched across the valve to effect interruption of current therein, the switching is effected by a contact-making relay 31 actuated by a series coil 2 on the D.C. side. Thus, in the event of excess current due to short-circuits or overload on the A.C. side, interruption is instantly effected and is maintained while the condenser is becoming charged for a sufficient time to permit of the device 26 being rendered inoperative by a negative charge on its grids 11. This condition is brought about by the drop in voltage in the grid transformer 12 which is normally effective to energize the grids 11 of the device 26 through current transformers 15 and valves 14, in opposition to a voltage derived from potentiometers 13. On such voltage drop occurring, the primary circuits of the current transformers are interrupted by the valves 14, whereupon the grids 11 are maintained at a negative voltage corresponding to the drop across a resistance 16 in the exciter circuit of the device 26. Interruption at the valve 37 may be rendered more effective by precharging the condenser in a sense opposite to the voltage across the valve. Such precharging is effected by a voltage transformer 19 operating through a valve 18 having a grid normally positively biased by a battery 22. Contacts 33 are provided on the relay whereby when the condenser is switched across the valve 37 a circuit is closed to produce negative bias on the grid of the valve 18, thus blocking the valve and thereby relieving the main contacts 31 of current. that would otherwise flow in the circuit parallel to the condenser.

The striking mechanism comprises a rack 15 movable into sensing engagement with an hour disc 14 stepped in accordance with the tooth spacing of the rack. The rack is stepped back into the initial position shown, on each stroke through an electromagnet 26 operating a pawl 31. A detent pawl 17 holds the rack at each step. This pawl has an arm 19 which extends into the path of movement of a detent 20 on a lever 22 carrying a gong clapper 29 and controlled by an armature 25 of the magnet 26. The detent 20 is so arranged that during the first stroke of the clapper, which releases pawl 31, the pawl 17 is also held disengaged from the rack which moves to engage disc 14. A wheel 11, meshing with relatively great tooth play with a wheel of the time train, makes one revolution per hour. Fast with wheel 11 are a lug 12 actuating a contact 32, and an armature rotatable between poles of an electromagnet 35. When contact 32 closes, magnet 26 is energized and armature 25 actuates, through a contact abutment 24, the clapper arm 22. The contact at 24 is thus broken and arm 22 closes a contact 37 to energize magnet 35. The tooth play of wheel 11 allows armature 34 to be pulled into line with the poles whereby contact 32 is broken and solenoid 26 deenergized. Arm 22 returns against an air dashpot 27. The circuit for magnet 35 is completed through a changeover switch 18 operated by the racks 15 so that this circuit is broken as soon as the rack leaves its initial position. When successive strokes of the hour are to be sounded, rack 15 moves through more than one tooth space so that on the first return movement of arm 22, a contact 18 I of the changeover switch is closed. Thus, through contact piece 24, a circuit is again immediately produced for solenoid 26 operating lever 22. This action takes place until rack 15 has returned to initial position wherein contact 18 I is broken and contact 18 II is made. A second striking mechanism 41-45 produces half-hourly strokes. In another embodiment, rack 15 is arcuate and switching lug 12 is moved mechanically to release contact 32 by a member moved by means connected with the arm 22.
