Title: Improvements in collecting electrodes for use in the electrical precipitation of suspended particles from gaseous fluids
IPC: B03C3/74
Filed: 1928-12-27
Abstract: 321,869. Lodge-Cottrell, Ltd., (Metallges. Akt.-Ges.). Dec. 27, 1928. Gases, treating electrically.-A collecting electrode for the electrical precipitation of suspended particles from gaseous fluids has a surface which is divided into a number of independently mounted strips which form slots between them and which may be independently jarred or shaken to effect the precipitation. The strips 4, Fig. 1, are suspended by hooks 2 and lugs 3 in transverse superimposed rows on both sides of an upright member 1. The strips are bent as shown with spaces 5 formed between the rows. The strips 4 are caused to knock against the carrier 1 by turning a shaft 6 provided with arms 7 engaging channel members on the strips. In a modification, the strips are bent so that their centres of gravity lie outside their supports, and are shaken successively at their lower and upper ends on rotating an armed shaft provided for the purpose. In the arrangement shown in Fig. 5, the strips 4 are suspended eccentrically by a support 11. A rod 13 has projections which loosely engage holes in the plates, and, upon the rod being hammered upon rotating the hammer shaft 16, the projections cause the strips to oscillate slightly about their supports. In a modification of this arrangement, the strips are eccentrically suspended from one end, and engage stops on a horizontal rod at the other end.

Title: Improvements in or relating to apparatus for displaying and dispensing liquids
IPC: B67D7/16
Filed: 1929-12-14
Abstract: 345,327. Dispensing liquids. WAGSTAFF, G. F., Brookfield, Newbold Road, Chesterfield, Derbyshire, and WAYNE TANK & PUMP CO., Ltd., 42, Newlands Park, Sydenham, London. Dec. 14, 1929, No. 38383. [Class 116.] An apparatus for dispensing liquids comprises a closed container 26, Figs. 1 and 2, in the transparent upper part of which air is trapped by the liquid, which is forced from a supply tank by air pressure to issue and fall as a thin film from the pipe 28. Air is delivered by a pipe 5 from a compresser 4 to a reservoir 2 and passes through a reducing valve 12 to a supply tank 3 divided into compartments 6, 7, 8, the upper portions of which are in free communication. Liquid from each compartment is forced through the corresponding pipe 28 whence it issues until equilibrium is obtained, through radial passages 43, in a plate 42, in streams which unite to form a thin layer. An outlet cock 32 of smaller bore than the pipe 28 and a revolving segmental door 20 for closing the front of the apparatus are provided. The outlet from the pipe 28 may be in the form of a gutter and the liquid may flow over a vertical or inclined transparent or reflecting surface.

Filed: 1928-12-29
Abstract: 303,478. Giorgio, G. de' (Assignee of Righini, U., and Bertuccio, M.). Dec. 29, 1928. [A Specification was laid open to inspection under Sect. 91 of f the Acts, Jan. 5, 1929]. Type-wheel machines; pad-inking arrangements; indexsetting arrangements; types.-To prevent fraudulent alteration the values of cheques, drafts, &c. are printed in characters which differ in size or shape according to their unitary value, the printing being effected by types arranged upon a series of type-bearing members each of which is provided with a complete set of types and is adjustable to bring any one of its types into position to print a single figure or cipher. The faces of the type may be adapted to perforate or cut the surface of the paper to enable the printing-ink to penetrate therein. Preferably the type-bearing members comprise discs s, Fig. 2, mounted upon a shaft b, Fig. 1, between end-bearings e which can be depressed vertically, against the pressure of a spring g, by cams c on a crank-shaft a. The discs are each provided with a radial lever t whereby they are rotated to set a line of type, retaining-springs u engaging notches in their peripheries serving to hold them in their set position. The faces of the set types are inked by a reciprocating pad m which receives ink from a roller n in an ink reservoir o and is connected by a telescopic rod to a crank on a shaft l geared to the driving-shaft a. A resiliently mounted block r supports the cheque during printing. When the figures denoting the value of the cheque &c. do not fill the space provided for them, asterisks or other signs may be introduced, as shown in Fig. 3.

Title: Improvements in and relating to electric regulating and controlling arrangements
IPC: G05B5/01
Filed: 1929-12-16
Abstract: 349,478. Automatic regulation. AKT.- GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Dec. 16, 1929, No. 38457. Convention date, Dec. 19, 1928. Addition to 307,046, [Class 38 (iv), Electric supply and transmission systems &c.]. [Class 38 (iv).] In a regulating device according to the parent Specification, in which equilibrium between the controlling effects of the quantity to be regulated and a quantity a comparison is produced in advance of actual agreement between them by a third factor the readjustment of the third factor which is controlled by the regulating operation takes place more slowly after equilibrium has been reached, with the object of preventing over-regulation. Moreover, regulating impulses may be suspended during this readjustment. As shown in the Figure a balance member 5 is displaced to effect regulation by want of equilibrium between a regulated quantity such as the voltage of a machine 1 operating on a coil 6 and a comparison quantity operating on a coil 7 and adjusted to determine the value of the regulated quantity by a resistance 9. The equilibrium is restored in advance of the restoration of the desired condition by a potentiometer 12 in series with the coil 7, which is adjusted in the required sense by a reversible motor 15. This motor is controlled by auxiliary contacts on relays 14a, 14b controlling the main reversible regulating motor 4 to displace the potentiometer contact member 18 in a suitable manner. According to the invention the return movement of this contact member which occurs on the return of the balance member to its mean position takes place at a slower rate than its prior movement by the inclusion of a resistance 20 in the circuit of the motor 15 by the contact 39a or 39b when the relay falls. The effect is to delay the succeeding regulating impulse and avoid over regulation. In a modification relay contacts in series with the motor 4 suspend regulation when the potentiometer contact is within a certain distance from its mid-position and relay contacts in series with the windings of the relays 14a, 14b prevent these from lifting their contacts during the readjusting movement of the potentiometer motor. In place of the resistance 20 a contact-breaker may be actuated by current flowing to the motor 15 during readjustment and effecting a reduction in its speed, e.g. if an A.C. motor, by placing resistances in its rotor circuit; alternatively the magnet of a brake may be energized bv the motor current. In a modification the motor speed may be changed by a contact-breaker or brake energized by the current flowing to the motor 15 prior to equilibrium and inserted for example at a. The speed variation may be effected in either case by electromagnetic reversal of a twospeed gear between the motor 15 and the spindle operating the potentiometer.

Connection tags 46 may be notched by stamping so that unused tags may be easily removed.

The cell is preferably formed on a monocrystalline substrate of Ge or Si on to which are sprayed electrode layers firstly of Al, through a mask, and then of Bi. A pure Se layer is then sprayed on and crystallized at 200‹ C. to form hexagonal Se having its c-axis along the substrate surface. The alloyed Se/Ag layer is sprayed on, after which the rectifying layer, e.g. of cadmium selenide or of Cd/Sn alloy covered with Sn, is applied.
