Abstract: 664,160. Electric indicating systems. GENERAL ELECTRIC CO., Ltd., and LUCK, G. A. Jan. 20, 1950. [Jan. 20, 1949] No. 1639/49. Class 40 (i). [Also in Group XL (c)] In testing rotary apparatus, wherein the variable being measured is translated by a pick-up into a corresponding electrical quantity, the necessity for slip rings to conduct the electric quantity from the rotary device to a stationary meter or indicator is avoided by transmitting the quantity by radio. Vibrations, torsional strain, centrigual force, stress, temperature etc., may be indicated in this way. The transmitter may include its own power supply in the form of batteries, or power may be supplied to it through slip-rings or from a generator rotating with the apparatus. As shown, for testing a turbine wheel for vibration, the turbine wheel 10 is secured together with a heavy recording wheel 50 to a stub shaft 32 adapted to be driven through a disengageable coupling 51, 52 by a motor drive shaft 56. The rotating turbine wheel is vibrated by a stationary electromagnet 60 and the vibrations of the wheel or blade 11 are detected by a pickup 12 secured to the recording wheel 50 in any of the radially arranged positions 62. The pick-up output is led by a lead 13 to a radio transmitter 14 secured within the hollow shaft 53 and connected to slip rings 16-19. The slip ring 16 acts as an aerial while the other slip rings are used to feed the external power supply to the transmitter. The coupling 51, 52 permits of easy disconnection of the lead 13 from the transmitter when the stub shaft 32 is removed for securing a fresh turbine wheel thereto. In operation the casing 37, 38 enclosing the rotating parts is evacuated by a vacuum pump connected to the duct 42. The transmitter may be frequency or amplitude modulated and at the receiver a C.R.T. indicator may be used. The transmitter may alternatively be mounted on the wheel 50. Two or more variables may be transmitted in turn by a single transmitter, or separate transmitters may be used for each variable.

Title: Improvements in and relating to bottle filling machines
IPC: B67C3/26
Filed: 1921-01-15
Abstract: 183,151. Littleton, F. W. Jan, 15, 1921. Bottling.-In a bottle-feeding mechanism in which the aerating-medium is passed into the bottle and the supply cut off before the liquor is introduced, a fixed disc is formed with ports which receive all the gas and liquor tubes of the apparatus, and an oscillating disc, fitting closely against the fixed disc, has ports adapted to register in sequence with the ports on the fixed disc. A fixed disc 2 is formed with a central port 5 connected to the outlet 3 of the tank 4 containing the liquor and gas, a port 5<a> leading to a filling- tube 6 in the bottle x, ports 8, 12 connected respectively to a gas-supply tube 7 and a gasrelease tube 11, and ports 8<a>, 12<a> communicating through a chamber 9 and annular passage 10 with the bottle. A disc 13 is formed on its inner face with ports 15, 16, 17, and is adjustably pressed by a spring 30 against a disk 2. An anti-friction roller 22 acts on an arm 18 on the disc 13 to cause the disc to oscillate on its spindle 14, and a similar roller acting on an arm 19 returns the disc to its initial position. As shown in Fig. 2, the ports in the discs 2, 13 do not register with each other and the bottle is isolated from the rest of the apparatus. A small movement of the arm 18 to the left causes the port 16 to connect the ports 8, 8<a> and the bottle is filled with gas. On further rotation the ports 15, 17 simultaneously connect the ports 5, 5<a> and 12, 12a respectively, and gas passing up the tube 6 sufficiently equalizes the pressure on each side of the ball valve 25 to allow it to open and permit liquor to flow into the bottle, the gas displaced therefrom passing through the chamber 9, ports 12<a>, 17, 12, and the' tube 11 to the tank 4. The roller 22 may be so mounted that, if a bottle is not in position to be filled, its raised holder acts on an arm to move the roller 22 out of operative position to prevent waste.

Abstract: 570,783. Reciprocating pumps. PARKER, H, and ROWLAND, T. C. E. Feb. 10, 1944, No. 2454. [Class 102 (i)] A reciprocating pump for delivering a lubricant or other liquid under pressure to a number of points comprises a delivery arm 38 on a rotary distributor 22 which, during the delivery stroke, is maintained in stationary pressure contact with a fixed ring 12 having a number of conduits 13 leading to delivery pipes 19, and which, during the return stroke, is held in position by a light spring 30 which acts on the distributor and permits it to be rotated from one position to another, some of the pressure applied to operate the pump plunger 27, 28.during delivery being transmitted to the delivery arm, and the dimensions of the parts being such that this pressure, with or without that of the spring, is sufficient to ensure a seal between the contacting surfaces of the delivery arm and the fixed ring. Liquid is fed to the pump casing 10 through a filter 83 and flows through slots 84, 85 and an inlet port 24 into the pump cylinder 26 from which it flows through an outlet port 25 and passages 39, 40 to the conduits 13. The passage 39 may communicate with a branch passage 42 fitted with a spring-loaded relief valve 43. The plunger part 27 is driven by means of an end cap 63 and a facing 81 provided on a pivoted idler arm carrying a roller 80 which bears on the face 77 of a cam 29 which is driven in either direction by worm gear 70, 71. When the gap 34 between the two plunger parts 27, 28 comes opposite the outlet port 25, a shoulder 36 on the plunger part 28 contacts a cap 37 on the end of the distributor 22 and keeps the arm 38 in contact with the ring 12. The delivery volume is controlled by adjusting the gap 34 by means of an eccentric pin 65 oscillatable through 180‹ and engaging a flange 67 on a sleeve 68 connected to the plunger part 28. An eccentric pin 57 on the cam 29 carries a square block 62 which slides in a radial slot 61 in an oscillating ring 55 carrying a spring- pressed pawl to engage a ratchet wheel 52 on the distributor 22 which is thereby given a step-bystep rotation. Backward movement is prevented by a spring-pressed registering pawl 47 engaging a stationary ratchet wheel 51. The pawl 47 is mounted on one of a pair of angularly spaced arms 44, 45 mounted on the distributor 22 to balance it against the offset pressure of the arms 38. Specifications 459,946, 480,978, and 517,974 are referred to.
