IPC: F16J15/447
Filed: 1963-07-19
Abstract: 996,546. Mechanical seals. ROLLS-ROYCE Ltd. July 19, 1963, No. 28650/63. Heading F2B. A sealing device for sealing between relativelyrotatable members 18, 19, Fig. 2, comprises a U-shaped seal part 56 which separates high and low pressure gas zones P 5 , P 6 , is sealingly mounted on one of the members (the member 19 as shown) with provision for axial movement thereon, and has two sealing projections 54, 55 on the limbs 63, 62 for coaction with the opposite faces of an annular part 61 projecting from the other member (the member 18 as shown), the intermediate gas pressure P 7  existing between the two projections being applied to at least one face of the seal part to maintain the latter in normal operation in an equilibrium axial position with each of the faces of the projections at a steady gap from the annular part 51. The members 18, 19 shown constitute respectively the shroud at the periphery of the blades 50 of a gas turbine and the casing. The projection 51 has flat annular faces 52, 53 for coaction with the faces of the projections 54, 55 of the U-shaped part 56 which is shown as being formed of two annular parts 62, 63 secured by bolts 64 and connected to the casing 19 by splines 66; the part 63 bears against a sealing ring 60 in a groove in a flange 57 projecting from the casing. The equilibrium position of the part 56 depends on the relative areas A5, A6 on opposite faces of the part. Movement of the part to the right from its normal position causes the pressure P 7  to fall, and movement to the left causes the pressure to increase, so that in either case the part tends to move back to its equilibrium position. In the modification shown in Fig. 3, the part 56 comprises a main part and an axially-movable sub-part 70 which is sealed to it by a ring 71, carries the projection 54, and has a labyrinth sealing face 72 coacting with an axially-extending face 73 on the part 18. In the further modification shown in Fig. 4, the part 18 has two annular projections 80, 81 co-operating with projections on the limbs of the U-shaped part 82 which has sealing engagement at 88 with a projection 89 on the casing 19 and bleed holes 90 connecting the intermediate pressure space with the low pressure side; in this arrangement, the U-shaped part 82 is provided with an axial split allowing it to be expanded for assembly over the projections 80, 81 where it is embraced by a continuous ring 94.

Abstract: 1292280 Reciprocating pumps TECALEMIT (ENG) Ltd 30 Dec 1969 [3 Jan 1969 6 June 1969] 595/69 and 28734/69 Heading F1A A non-cavitating lubricating pump comprises a bucket piston 23 reciprocable within a cylinder 14, 18 defining chambers 15, 32 and mounted in a reservoir 2, the piston being actuated downwardly against the action of a spring 24 by means of a pivoted lever 10 acting on the piston 23 through a rod 33, the lever 10 being operated manually, or mechanically through a flexible cable 7. During the downstroke, liquid is displaced from chamber 32 to chamber 15 via a passageway 27 and a non- return valve 28 in the piston, 23. On the upstroke, effected by the spring 24, a further charge of liquid is drawn into chamber 32 via a filter 19 and a non-return valve 20, and the liquid in chamber 15 is expelled via an outlet port (16), Fig. 2 (not shown) cavitation in chamber 32 being avoided by selecting a spring of sufficiently low spring-rate. To provide a reduced pumping rate, in a modification, Fig. 4, the cable 7 acts on the piston rod 33 through a cam 48 and a pawl 53 and ratchet 48. Each mechanical pulse on the cable 7 produces, via the pawl and ratchet, a small rotation of the cam 48, which is shaped to produce one pump stroke per revolution. In a further modification, Fig.6, a further gearing reduction is obtained, each mechanical pulse on the cable 7 now producing a small rotation of cam 74, one rotation of which produces through a second pawl and ratchet a small rotation of cam 68 which acts on the piston rod 33 and produces one stroke per revolution.

Title: Improvements in or relating to arrangements for charging electric accumulators
IPC: H02J7/00
Filed: 1923-11-14
Abstract: 229,372. Automatic Telephone Manufacturing Co., Ltd., and Remington, C. Nov. 14, 1923. Systems of charging and discharging galvanic batteries.-A system embodying accumulator batteries having large gassing and acid space is arranged so that whenever and so long as current is taken from the battery, either that battery or another is connected to the charging mains. Assuming the armatures 5, 6, Fig. 1, have been moved to the right, a " holding-on current is obtained from the battery 1 through armature 5, and armature 6 acts as a relay to energize an electromagnet 4 to move armatures 7, 8 to the right thereby connecting battery 1 to the load circuit 9, 10. Whenever current is taken from the circuit 9, 10 the relay 12 connects the charging mains 13, 17 to another battery 2. When the battery 1 becomes discharged the " holding-on " circuit through armature 5 is too weak to retain armatures 5, 6 which thereupon move to the left. This movement causes de-energization of electromagnet 4, and also armature 5 completes a circuit to energize an electromagnet 18, the movement of the associated armatures 20, 21 respectively completing a " holding-on " circuit from the battery and energization of electromagnet 22. The consequent movement of the armature 19 interrupts the circuit from battery 1 through armature 5 and electromagnet 18, and the movement of the armatures 15, 16 together with the previous release of armatures 7, 8 interchange the batteries 1, 2 in respect of the circuits 9, 10 and 13, 17. In a modification a current in the load circuit 30, 31, Fig. 2 causes the relay 33 to complete the filament circuit of a two electrode thermionic valve 28 for the purpose of supplying rectified current from a transformer 27 to a battery 29.

Title: Improvements in or relating to stopping-place indicators for vehicles
IPC: B61D41/00
Filed: 1935-10-18
Abstract: 458,875. Changing signs. AMBI-BUDD PRESSWERK GES., Gross-Berliner Damm, Johannisthal, Berlin. Oct. 18, 1935, No. 28820. Convention date, Oct. 27, 1934. [Class 3 (i)] The display band 5 of a stopping-place indicator for vehicles has the indications A for the outward journey interspersed with those B for the inward journey, thus rendering a long re-wind of the band at one end of the double journey unnecessary. The band is advanced at each actuation through the space of two indications, and when electric means are provided for effecting the advance, metal contacts 10, 10<1> are mounted in staggered relation on both sides of the band. The contacts 10, 10<1> may comprise pieces of metal foil secured to the band by adhesive, or metal applied by a spraying process. The contacts complete the circuit through each of two pairs of spring-pressed rolls and effect stopping of the driving motor and lighting of a lamp or lamps disposed behind the band. A shortcircuiting device for the motor is also put into operation to bring same to a rapid stop. The motor is re-started by manual opening of a switch which de-energizes a relay and allows its armature to switch in the motor and cut-out the lamps. The motor is reversed at the end of a wind by tilting by a handle 17 a plate 12 carrying the motor 7 and gear wheels 14, 15 which can thus be brought into engagement with one or the other of the band rollers. One of two contacts 20, 21 on the plate 12 is brought against a pin 21a extending through a slot 20a in the plate and makes the circuit through one or the other of the contact rolls. The plate 12 carries also spring-pressed brake blocks 19a, 19a<1> which bear on one or the other of discs 19, 19<1> on the respective band rollers, thus keeping the band taut during winding. The rollers have a sponge rubber or like soft coating, and are adapted for ready fixing and dismounting by providing at each end a non-integral flange having a radial slot along which a non-circular boss on the roller can pass, the boss being retained when in coaxial position by turning the flange through 90‹. A spring-pressed pin engages holes in the flange to retain it in each of its end rotational positions.

Abstract: 295,699. Burroughs Adding Machine Co., (Assignees of Racz, E.). Aug. 19, 1927, [Convention date]. Type-bar actions.-Printing-mechanism for a calculating-machine comprises type-carriers each of which is movable for type-selection and impression and is provided with two or more relatively movable typebearing parts so controlled that only one part at a time is effective for impression; the arrangement enables the type-carrier to bear an abnormal number of types without increasing the normal selective travel, since the types immediately adjacent to the selected type are ineffective for impression and smudging is therefore obviated; or the arrangement enables the selective travel of a type-carrier bearing a normal number of types to be shortened. The type-bar shown in Figs. 1, 2, and 5 bears sixteen types 31 for printing annas, and consists of two parts 16, 17 formed with alternating type-bearing lugs 30, 32 and alternating projections 50, 51, the two parts being guided by slots 53, 52 which are formed in a plate 48 and have shoulders 55, 54 for engaging the projections 50, 51. The two parts are pivoted to two sectors which are secured together and are controlled by amount keys 10. The two parts engage hammers 34, 35, the hammer 35 having lugs 36, 37 engaging the hammer 34. The hammers are connected to actuating-springs 42 and either or both the hammers have tails co-operating with latches 39 adapted to retract and then release the hammers. On depressing one of the keys and operating the main shaft of the machine, the type-bar is raised, the hammers are operated, and the two parts are moved towards the platen 22. If the selected type is on the part 16, that part is permitted by the shoulder 55 to complete its impression stroke, whilst the part 17 is arrested by the shoulder 54 and one of the projections 51. Similarly, if the selected type is on the part 17, that part only completes its impression stroke. Specification 265,140 is referred' to.

Abstract: 990,739. Surgical tables. RITTER CO. Inc. Aug. 11, 1961 [Sept. 26, 1960], No. 29106/61. Heading A4H. In a hydraulically operated surgical table, the femoral section 43 is arcuately guided with respect to the pelvic section 42 so that, during upward tilting, it moves about the axis 326 and during downward tilting, it moves about the axis 332. The axis 326 is approximately in line with the hip joint of a patient lying on the table. The outward motion imparted by hydraulic ram 47 at point 301 constrains rollers 302 and 303 to move along guide channels 304 and 306 and thus tilt the section 43 upwardly. The contraction of ram 47 causes roller 303 to move along guide channel 307 and the section 43 to pivot downwardly about axis 332. Specifications 990,736 and 990,737 are referred to.
