Title: Centrifugal pump
IPC: F04D9/04
Filed: 1923-11-13
Abstract: 206,858. Neumann, F. Nov. 13, 1922, [Convention date]. Starting, facilitating; casings; cooling and heating parts.-A liquid-ring air pump c, for priming a centrifugal water-pump for use on fireengines is mounted on the same shaft d and in the same casing as the water pump and is supplied with the water for the water-ring from the water-jacket b through the valve a. The water in the jacket b also circulates in the jacket of the driving internal-combustion engine. When the water pump is working, the air-pump c is usually rendered inactive by opening the valve g, water passing through the passage h to lubricate the pump a. At great suction head, however, the pump a remains in action to draw off the air which separates out in the suction pipe. The valves a, g may be coupled to other controlling elements.

Title: Improvements in or relating to pneumatic brake systems for vehicles
IPC: B61L3/12
Filed: 1936-10-21
Abstract: 483,574. Fluid-pressure brakes. HUDD, A. E. Oct. 21, 1936, No. 28649. [Class 103 (i)] In vehicles such as railwav vehicles, in which brakes are automatically applied, when signals are at " danger," by the opening of a valve in a pipe-line connected to the various brakes, the valve 65 is operated by a pressuregovernor 58 which is controlled by the difference in pressures in the pipe-line 67 and in a vacuum chamber 62, which latter is caused to vary at a predetermined rate corresponding to the required rate of application of the brakes. The governor comprises a chamber divided by a diaphragm 61 connected to the valve 65 which controls an inlet 66 into the pipe 67. The upper compartment communicates with the inlet by a port 68 and the lower one with the chamber 62. Near each signal two magnets are arranged as described in Specification 477,319, [Group XXX], which also describes the receiver shown at the righthand side of the Figure. The magnet 10 of the latter controls a valve 12 at the end of a pipe 34 leading to the lower compartment 42 of a diaphragm casing 40. A slide valve 55 is carried by the diaphragm 43. When the receiver passes a signal at " danger " the valve 12 is opened, the balance of pressure in the casing 40 is upset, and the diaphragm and valve 55 rise. A horn 53 is thus connected to a vacuum chamber 73 by way of a pipe 52, ports 49, 50, and a pipe 44. The horn then sounds. Also the pipe 54 then communicates with the air through a bleed hole 6. The valve 65 opens after a delay when the difference of pressures in the governor 58 exceeds the force of a spring 69 and of the external air due to the vacuum in the pipe 67, on the valve. The rate at which pressure rises in the compartment 60 depends on the sizes of the chamber 62 and of the hole 6. When the valve 12 is closed by the driver the compartment 42 is evacuated, whereupon the diaphragm 43 descends and carries the valve 55 into its lowest position as shown. The vacuum in the chamber 62 is then restored. The magnet 10 may be reset by means of a push-button 8. When the valve 65 rises the inrush of air operates a siren 72.

Title: Short length adhesive tape feeder
IPC: B65C9/18
Filed: 1959-08-24
Abstract: 881,442. Applying tape to box-blanks. UNIVERSAL CORRUGATED BOX MACHINERY CORPORATION. Aug. 24, 1959 [Sept. 9, 1958], No. 28877/59. Class 73. A machine for applying adhesive tape to a moving work-piece comprises a pair of tape feeding rollers. 95, 107 and a single pair of complementary cutting members 87, 101 one each of which, 95 and 87 respectively is movable towards the other, controls actuated by the moving workpiece cause tape between the rollers 95, 107 and cutters 87, 101 to be alternately fed and severed into lengths dimensioned according to the adjustment of the controls, and transfer means 151 beyond the cutters which has means around its periphery to retain the severed length of tape and which rotates to move it and release it continuously for application to the moving workpiece. The workpieces are box-blanks 12 which are moved along a conveyer belt 16 on to which they are held by adjustable roller-assemblies (Fig. 1, not shown). The feed rollers are journalled between a pair of parallel cheekplates (one only shown at 34 in Fig. 4) which are suspended from a beam 31 and are adjustable for height above the conveyer 16 by a ratchet 51 and screw 43. The controls are microswitch fingers spaced along the belt of the conveyer 16 (Fig. 1, not shown). Unmoistened adhesive tape is led from a roll over a roller 52. An eccentrically mounted roller 56, bias weighted at 57, nips the tape against the roller 52 to prevent reverse feed. Fingers 63 extend from a support 61 along grooves in the cylindrical surface of the driven roller 107 to guide the tape on to the inclined anvil 101. A yoke 71 (Figs. 9 and 10) pivoted between the cheek-plates 34, at 78 carries the free roller 95 and also a cross-bar 74 which adjustably houses a knife 87. A lever 75 on the bar 74 is urged downwards by a spring 147 so that the roller 95 is normally withdrawn from the surface of the roller 107 and the knife 87 is held against the anvil 101. Beyond the anvil 101 the transfer roller 151, Fig. 7 is mounted on a spindle 158 and a suction pipe housing 177. A stationary sector 183 inside the roller 151 successively masks suction holes 157 over a sector of about 180 degrees of the circumference around which they are spaced. A shaft and pinion assembly 167 drives the roller 151 synchronously with the roller 107 and with a tape-wetting assembly 204. When the blank 12 on the conveyer 16 reaches the first microswitch finger it operates solenoid 126 which, through a link 133, raises the lever 75. This lifts the knife 87 from the anvil 101 and causes the roller 95 to press the tape against the driven roller 107 which feeds the tape forward. At the second microswitch the solenoid releases the lever so that the knife 87 falls to cut a length of the tape. The cut piece of tape is then picked up by the suction holes 157 of the roller 151 and carried down to the blank 12, whereupon the sector 183 operates to cut off the suction and release the tape.

Title: Improvements in submarine signalling
IPC: H04B3/00
Filed: 1929-09-24
Abstract: 340,042. Western Electric Co., Ltd., (Bell Telephone Laboratories, Inc.). Sept. 24, 1929. Telephone currents, inverting and transposing frequencies of; two-way repeating systems; phantom circuit systems.-The frequency range of signals to be transmitted over a submarine telephone cable is divided into a. number of bands which are continuously transmitted over different physical and phantom call circuits. By transposing the bands to occupy the position corresponding to the lowest band, the maximum frequency transmitted over any circuit is greatly reduced. Where the range is divided into two bands, the physical circuit may comprise a twocore cable or two cores in separate cables, and the phantom circuit comprises the two cores in parallel with armour or sea return. A balanced two-core cable suitable for present use is described in Specification 339,968, [Class 36, Electricity, Conducting &c.]. When the range is divided into four bands two bands may be transmitted over the pairs of two-wire circuits of a four-core cable, a third over phantomed pairs, and the fourth over all four wires in parallel with ground return. In the two-band arrangement shown, speech incoming over 10 is divided into bands of 0-1000 cycles and 1000-2000 cycles by filters 12, 13, the output of filter 13 being transposed to 0-1000 cycles by modulator 14. Voice-operated relay 15 connects one path over transformer 19 to the physical cable circuit and the other path over transformer 18 to the phantom circuit. Signals incoming from the physical cable circuits are demodulated at 20 and passed through filter 22, while the signals over the phantom circuit are passed through filter 21, the combined output of the filters being amplified at 23. A voice-operated relay in the output circuit short-circuits relay 15.
