By removing the cover k, the whole rotor may be lifted from the casing i. The turbine discharges at the point e into the delivery .chamber f of the pump. Figs. 2 and 3 show constructions wherein pressure from the turbine supply chamber c is transmitted through ducts l, l<1> to pump or turbine surfaces m, m<1> for balancing axial thrust. Leakage-fluid also acts on the surface m<2>, Fig. 3, and flows through a passage q to the suction chamber of the pump. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the statement that the channel q may be used for supplying liquid to the pump on starting. To facilitate transportation, the casing may be shaped so that it can be rolled along the ground. The turbine and pump rotors may be joined by a screw connexion which the rotation of the turbine tends to tighten. This subject-matter does not appear in the Specification as accepted.

Title: Electromagnetically driven counter
IPC: G06M1/10
Filed: 1951-08-31
Abstract: 748,542. Counting-apparatus. STANDARD TELEPHONES & CABLES, Ltd. Aug. 31, 1951 [Aug. 31, 1950], No. 20603/51. Class 106 (1). A counter comprises a plurality of numeral wheels each of which is advanced in step-by-step manner by means of a pawl-andratchet mechanism actuated by an electromagnet. Each wheel has a projection which closes the circuit of the succeeding electromagnet to effect transfer. For zerozing each electromagnet is repeatedly energized until a projection on the associated wheel opens the electromagnet circuit. Each numeral wheel 11, Fig. 1, its actuating mechanism and electromagnet are mounted as a unit. The two solenoids 2 are fixed by screws 3 to a U-shaped member 1 which carries the brackets 16, 17, Fig. 2, between which the wheel spindle 15 is mounted. The armature has two arms 7 and 4 and is pivoted at 5. A spring pawl 6 is fixed by screws 9 to the arm 4 and cooperates with a ratchet wheel 10 fixed to the numeral wheel. The numeral wheel has two projections 13, 14 which co-operate with two spring contact switches 23, 24 as described later. In operation when the electromagnet 2 receives an impulse from a stepping relay 43, Fig. 6, the armature 7, 4 is rocked clockwise to lift the pawl 8 on to the succeeding tooth of the ratchet 10. When the impulse ceases the electromagnet de-energizes and the pawl 8 steps-on the ratchet 10 and the numeral wheel 11. Transfer. When the numeral wheel reaches " 9 " the projection 13 closes the switch 23 so that the circuit to the next higher electromagnet 2 is closed. The two electromagnets will thus be energized upon the reception of the next impulse and their associated numeral wheels stepped on. Zeroizing. All the electromagnets 2 are connected to a relay 44, Fig. 6, each through a circuit including the normally closed switch 24 which is opened upon each movement of its associated armature. Each magnet is therefore repeatedly energized and its associated numeral wheel stepped-on upon operation of the restoring relay 44. When a numeral wheel is at zero its projection 14 maintains the switch 24 open so that the circuit to the electromagnet is broken and the wheel remains stationary.

Abstract: 884,219. Seaming non-metallic sheet material. RADYNE Ltd. June 14, 1960 [June 17, 1959], 20820/59. Class 42 (1). A rotatable work-table for a welding press has a plurality of work areas, an indexing means whereby the table can be rotated to bring each work area in turn into operative index position in the welding press and a braking device operative shortly before an index position is reached to brake the rotation of the work-table. The invention is particularly applicable to the welding of thermoplastic material by dielectric heating and in the Fig. 1 indicates a rotating table which passes between the electrodes 8 of the welding press. A roller 2 is arranged to run along the periphery of the table and is carried by a beam 3 pivoted to a fixed point 4, the other end of the beam being connected with an air cylinder 7. A recess 6 is provided in the edge of table 1 just prior to each index position and is shaped with a gently sloping lead-in side 6a and a steep lead-out side 6b. Thus, shortly before the table 1 reaches an index position it must move the roller 2 rapidly outwards against the spring 5, thus producing a braking action on the table. Additional pressure is also applied to the movement of the roller outwards by air cylinder 7 (or an electromagnetic solenoid).
