Title: Improvements relating to apparatus for indicating or recording the rate of flow of fluids
IPC: G01P5/07
Filed: 1933-06-08
Abstract: 425,160. Logs; flow meters. CHERNIKEEFF & CO., Ltd., Parliament Mansions, Orchard Street, Victoria Street, and PETROFF, A., 106, Edith Road, West Kensing- ton, both in London. June 8, 1933, No. 16448. [Class 97 (ii)] A ship's log or a flow meter comprises a submergible compact electric make-and-break and screw rotator unit and means for providing a continuous flow of lubricant from an external source through the unit. In the ship's log shown, a bronze elongated member a of streamline section terminates in a transverse hollow open-ended cylinder a<8> forming a shroud for the rotator s. The latter has its supporting shaft mounted in a closure disc c adapted to be secured by the screwed flange c<3> over the open end of a streamlined chamber b which contains the make and break mechanism and is supported by a member a arranged diametrically across one end of the cylinder a<8>. The make-and-break mechanism is carried on the closure disc c and comprises a star wheel adapted to close spring contacts and driven through a lost motion device to eliminate sparking by gearing h, h<1>, h<3> operated by the rotator shaft. The chamber b has two apertures which when the chamber is in position coincide with the openings of two passages b<8>, b<9> in the member a. A non- return valve b<10> controlled by a spring b<11> closes the aperture opposite the passage b<8> which serves as a lubricating duct. Cables passing down the passage b<9> connect an indicating or recording instrument to contacts b<3>, b<4> in an insulating bush b<2> screwed onto the second aperture. The contacts b<3>, b<4>, engage spring contacts f<3> connected to the make and break mechanism. In operation the chamber b is filled with oil and a partial vacuum which arises in the space between the cap c<3> and the inner face of the rotator boss s<2> promotes induction of the lubricant through the non-return valve b<10> and eduction through the gland of the rotator shaft. The lubricating duct b<8> is connected by pipe m<1>, Fig. 10, to a cylindrical, oil-filled, chamber m, mounted on the top of the member a. The oil in the chamber m is compressed by a piston m<2> urged downwards by a spring n<3> the tension of which may be adjusted as required by the hand wheel n. A perforated cover r is fixed over the open end of the shroud a<8>.

Title: Metal enclosed switchgear
IPC: H01H33/12
Filed: 1967-04-11
Abstract: 1,140,288. Switchgear structures; electrically released switches; actuation of switches. S & C ELECTRIC CO. 11 April, 1967 [23 May, 1966], No. 16548/67. Heading H1N. Switchgear comprises a metallic housing 17, Fig. 6, having a door 22 on which is mounted a fuse 85. A switch blade 105 interconnects the device and a fixed contact 134 within the housing, and interlocking means are provided to prevent the opening of the door when the blade 105 is in its closed position. The interlocking means may comprise out-turned portions 90 of a contact 88 on the fuse 85. These portions 90 engage behind arcuate flanges 126 of contact members 124 on the blade 105. The door 22, Fig. 2, has a latch bar 38 movable by a door handle 26 which has a detent 49 co-operating with a pawl 54. This pawl is connected by flexible cables 62 to a locking lever 65 effective to latch the switch-operating handle 33, and to a locking lever 74 effective to lock the switch blade 105. This arrangement prevents the unlatching of the door when the switch is closed and the operation of the switch when the door is unlatched. When the switch blade 105 is moved to open the switch, a member 145 engages a metallic housing 143 to transfer the current path to a circuit interrupter 136. The member 145 also engages an opening arm 144 to open the circuit interrupter 136 which is of the kind having a contact 137 movable in an insulating tube and carrying an insulating trailer 138. Closing of this interrupter 136 is effected by a closing cam 148 operating a closing lever 147 as the blade 105 is moved to its closed position. The switch operating mechanism, Figs. 15 and 21, includes an overcentre compression spring 239 which may be compressed and moved into a position just overcentre by the operating handle 33 ready to open or close the switch. In each of these overcentre positions a latch hook 291 or 292 latches a pin 286 on a switch operating lever 212. The latch hook 291 or 292 may be operated to release the pin 286, so that the spring 239 can move the lever 212 to close or open the switch, by a push-button 301 or 302 respectively or by a " closing " coil 299 or " opening " coil 300 respectively. The latch hooks, &c., may be omitted so that the mechanism functions as a simple overcentre snap-action arrangement.

Title: Improvements in variable-speed gearing
IPC: F16H39/36
Filed: 1936-06-15
Abstract: 462,507. Hydraulic transmission of power. BEIER, J. June 15, 1936, No. 16618. [Class 69 (ii)] [Also in Groups XXIV and XXVI] A hydraulic clutch 22 is intermittently engaged for periods of manually or automatically controllable duration, to take energy from an energy-storing device, such as a fly-wheel constituted by the driving casing 22 of the clutch, such energy being delivered, through an intermediate shaft 39, to a second energy accumulator such as an internal torsion-spring 45, connected to the load at 46, and prevented from unwinding in the reverse direction by a hydraulic ratchet 37. The driven member also carries a fly-wheel 46. The hydraulic clutch comprises an intermittently throttled liquid pump, constituted by a planet gear 24, Fig. 2, carried by the driving casing 22, and a driven sun-wheel 23, secured to the shaft 39, the pump-outlet being intermittently closed by means of a cylindrical valve 25, which is continuously rotated by a planetpinion 26, engaging a stationary sun-wheel 27. The duration of the intermittent clutch engagements is controlled by sliding the valve 25 axially, such sliding being effected through the pinion 27 and rods 36, by means of a lever 53 and screwed sleeves 54, 50. The lever 53 may be operated manually and by means of a speed-responsive governor driven by the driven shaft of the gear. The control of the valve 25 is also made dependent on the torque of the driven shaft by means of the torsion-spring 45, the rotary yield of which turns the screwed sleeve 50. The hydraulic ratchet, which may be adapted to function in either direction of drive, comprises a gear-wheel 37, Figs. 1 and 3, fast on the intermediate shaft 39, and cooperating with a gear-wheel 38, carried in a stationary liquid-filled casing 41, to form a pump, the delivery of which is checked in one direction only, by a spring loaded valve 43. In order that the detent may be used to brake the driven shaft, there is a manual controlwheel 59, which depresses a pin 57, thereby positively holding down the valve 43 and preventing rotation of the shaft 39 in both directions.

[Also in Division F2] In an article transfer apparatus having a suction or gripping holder 4, articles, during transfer, remain in the same plane. In Fig. 2, the holder is attached to an arm 3 pivotally connected to a further arm 2 which is itself pivotally connected to a stationary arm 1. Figs. 2A-2E show a sequence of positions of the arms 2, 3 during movement of the holder 4 from one end of its stroke to the other. In Fig. 2F the holder is returning to its starting position. Details of arms 1-3.-The lower end of the stationary arm 1 rotatably supports a shaft 5 to which rotational reciprocable movementmay be given by a sprocket and chains 7, 8. Rotatable within the shaft 5 is a shaft 10 which is splined to a flange 12 bolted to the arm 1 and which at its other end has a sprocket 15 engaging a chain 19 within the arm 2. A shaft 16 rotatable in the upper end of the arm 2 is secured to the arm 3 and to a sprocket 18 also in engagement with the chain 19. A shaft 20 is rotatable within the shaft 16 and has one end connected to the arm 2 by splines 32, the other shaft end carrying a bevel gear 21. This gear, via gear 24, shaft 23 and bevel gears 25, 28 drives a shaft 27 to which are secured, by splines 29, 29<SP>1</SP>, arms 29, 29<SP>1</SP>, arms 31 of the holder 4. Ratios of sprocket diameters and of the bevel gears to produce the straight line movement of the holder 4 are specified. Drive details.-The reciprocating movement of the chain 8 is derived from continuous unidirectional rotation of an arm 61 which carries a link 63 having a stub shaft 64. This shaft pivotally engages one end of a rod 66 and carries a roller 65 which bears on cams 53, 57, 58 fixed to a stationary member 54. The rod 66 has its other end pivotally connected to a member 72 joining the ends of chain 8. A shaft 51 on which the arm 61 is mounted is driven from a motor through reduction gearing. The contours of the cams 53, 57, 58 in co-operation with the roller 65 produce the required reciprocation with two rest periods corresponding to flattened cam portions 55, 56 and 59, 60. Should the holder 4 be subjected to an abnormal impact load an arm 38 connected to the shaft 20, swings laterally and opens a valve controlling an air conduit 47 connected to a relay for stopping operation of the apparatus. The positions of the arm 2 relative to the arm 1 and of the holder 4 relative to the arm 3 may be adjusted by bolts (14, 36) which pass through slots (13, 35), Fig. 4 (not shown).
