Title: Improved means applicable for use in "dipping" articles of earthenware or pottery
IPC: B28B11/04
Filed: 1929-09-27
Abstract: 339,395. Wade & Son, Ltd., G., and Wade, G. A. Sept. 27, 1929. Coating-machines.-A device, for dipping pottery or earthenware into glazing or colouring liquid comprises a table or platform which can be lowered to a predetermined level in a tank containing the glaze, and a device for keeping the surface of the glaze at a constant level. The table a, Fig. 1, is secured to the lower end of a vertical rod b which slides in an axial direction through guides b<1> secured to a frame c above a tank k containing the glaze. A pivoted lever d enables the rod to be moved through the guides, and a counterbalance e on the lever normally maintains the tables a, and the article it supports, in the uppermost position. A collar f adjustably secured to the rod, determines the lower limit of the movement of the rod. The level of the glaze in the tank is kept constant by any suitable device such as a receptacle l with a tube l<11> which extends downwards to the surface of the glaze. In use, an article is placed on the table and is lowered into the glaze to a. distance regulated by the collar f successive articles thus being dipped in the glaze to the same extent. In order to allow air to escape from the interior of hollow articles, a U- shaped tube h is provided one end of which projects upwards through the table while the other end passes upwards into a chamber g, Fig. 5, containing water and a, hollow float g<1>. A blowoff cock h', Fig. 1, is also fitted to the pipe. A hollow article is placed on the table a over the end of the pipe h, and when lowered into the glaze, the air contained in the article passes to a greater or less extent into the interior of the float g<1> thus relieving the pressure of the air within the article. The contained air may be allowed to escape through the cock h' when it is desired to glaze the whole of the inner surface of the article.

Abstract: 681,874. Rotary meters. POTTER, D. M. Dec. 1, 1950 [Dec. 2, 1949), No. 29505/50. Class 110(ii) The rotor 16 of a meter is provided with surfaces facing upstream and downstream, in a tube 10, which co-act with fixed surfaces, the whole being arranged so that the rotor is balanced or substantially balanced axially and the bearings of the shaft 19 are practically free from end-thrust. Due to fluid flow. static and dynamic pressures acting on the rotor vanes 16a and rotor surfaces 13b, 13c tend to force the rotor downstream, but the fluid flowing through a restricted annular passage 12, having an outer fixed ring 14, and acting upstream on the surface 13c cause balancing forces to be exerted on the rotor. The rotor may have some axial freedom to allow for fluid surges or to clear the rotor vanes of a piece of foreign matter such as lint or paper. The shaft 19 is mounted in bearings carried by a shield 15 and a stream-line support 20. The speed of rotation of the rotor 16 is measured, preferably, by known electrical means comprising a ring magnet 22 and a coil 23 which is electrically connected to a tacheometer or frequency meter 24. In a modified arrangement, Fig. 5 (not shown), the rotor is carried within a sleeve in the tube 10. The portion 13 may be hollow to reduce its weight. The tail end portion of the rotor may be of reduced diameter.

Abstract: 804,713. Automatic voltage control systems. STONE & CO. (DEPTFORD), Ltd., J. Oct. 18, 1955 [July 20, 1954], No. 29682/55. Divided out of 804,711. Class 38 (4). In a system in which the field of a generator is excited from an A.C. supply via a rectifier and a saturable reactor, the reactor is automatically controlled so as to give constant voltage control up to a certain load current and constant current control thereafter. As shown, the generator is a self-excited alternator supplying an external load via a main rectifier, but it is stated that it could be a D.C. generator having either a tapped armature winding, an auxiliary pole-face winding, or even a separate A.C. generator to provide the necessary A.C. for the field supply. The alternator 1 charges the battery 2 over a main rectifier 3 and is selfexcited over a rectifier 5 and saturable reactor 8. The reactor 8 has a reference winding 6 in series with a barretter 7 and a main control winding 9 connected across both the battery and the rectified output of a load current transformer 12. The rectifier 11 which is connected to the current transformer 12 is blocked until the load current rises to a predetermined value when it conducts and energizes the winding 9 to reduce the output voltage to maintain the current constant. In a modification, Fig. 1 (not shown), the reference winding 6 is in shunt with a neon tube instead of in series with the barretter. It is stated that the reactor with permanent magnet reference and additional feed-back windings as disclosed in Specification 804,711 may be used instead of the simple reactor.

Title: Improvements in or relating to means for controlling a series of electrical contacts
Filed: 1947-11-11
Abstract: 657,092. Controllers; actuations of switches. WEST & CO., Ltd., A., and JOHNSON, C. Nov. 11, 1947, No. 29982. [Classes 38(iii) and 38(v)] A switching apparatus comprises a series of sequentially operated electrical contacts respectively associated with fluid pressure devices each of which actuates its contact when fluid under pressure is admitted to the said device in response to the movement of a rotatable control element. In the arrangement shown, a number of movable contacts 1, 2 arranged in two sets are respectively connected to tappings of two resistance sections (not shown). Contacts 1, 2 are selectively and sequentially engaged with two bus-bars 3 in series so that a portion of one section of the resistance is in series with a portion of the other resistance through the bus-bars 3. The arrangement is such that the two resistance portions in circuit are simultaneously increased or decreased. A vertical drum 7 is provided at the centre of the apparatus and has a series of small ports 8 in its cylindrical wall which communicate with respective spaces 6 beneath diaphragms 5. A rotatable air supply device comprises two air heads 10 mounted in a vertical shaft 11 rotated within the drum 7 for example by a pilot motor 28 through gearing. A flexible air pipe 12 leads to two air pipes 13 which in turn lead to ports 14 in the air heads 10. The ports 14 break out at the outer surfaces of said air heads which are in sliding engagement with the inner surface of the drum 7. The diaphragms 5 are of thick rubber and each is bonded both to a rod 4 and to an inner surface of a cylinder 16. The rods 4 actuate the contacts 1, 2 through insulated brackets 19. All the cylinders 16 of each row are closed at the lower end by a common base plate 17, and, at their upper ends they are closed by individual heads 18 in which the rods 4 slidably bear. To minimize air leakage at the engaging surfaces of the drum 7 and air heads 10, springs 15 are provided to thrust radially outwards the air heads 10 against the wall of the drum 7. In order to ensure that one of the contacts 1, 2 cannot cease to be actuated until the next adjacent one is actuated each port 14 is elongated in a circumferential direction as shown at 14a so that two ports 8 are always in register with a port 14. The Provisional Specification also describes a modified form in which the cylinders are mounted on the upper surface of a common horizontal base ring provided with a series of small holes. The two air heads rotate outside the drum about the common axis of the apparatus and as they rotate they slide over the under surface of said base ring. Flexible air pipes lead to ports in the air heads the ports of which break out at the upper surfaces of the air heads so that as the latter simultaneously rotate, their ports successively register with the holes in the base ring and thereby the cylinders are successively supplied with compressed air. Specification 589,626 is referred to.
