Title: Ht voltage measurement
IPC: F02P17/02
Filed: 1965-07-15
Abstract: 1,114,132. Voltage measurement. R.W. ELDRED. July 11, 1966 [July 15, 1965], No.31085/66. Divided out of 1,114,131. Heading G1U. An arrangement for measuring voltage, such as that arising at the spark plug of an I. C. engine, includes a resistive potential divider for scaling down the voltage in a known proportion. The output from the divider is supplied to one input of a monostable multi-vibrator and adjusted until the multi-vibrator changes state, the change of state being indicated by a meter or other device. The variation between the maximum and minimum voltages at a spark plug can be determined by setting the potential divider to zero and adjusting it until the multi-vibrator just changes state occasionally, the indicator showing that the circuit is just pulsating irregularly. Further adjustment is then carried out until steady pulsation is observed.

IPC: H01Q19/13
Filed: 1957-10-09
Abstract: 846,943. Aerials. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Sept. 17, 1958 [Oct. 9, 1957], No. 31561/57. Class 40(7). A reflector 1 of parabolic cheese form having end plates 2 and 3 flared outwards along their outer edges as indicated at 4 has its radiation pattern improved by minimizing and compensating for the effect due to obstruction of the horn mouth by the primary element. In order to do this a plurality of equally spaced and like partition plates 5 are arranged parallel to the focal line of the reflector to subdivide the aperture into a plurality of similar sections. The spacing of the plates is such that the phase distribution across the aperture is the same as that which would occur if the partitions were omitted. The primary element 6 is mounted at the end of feeder 8 and is backed by a metal shield 10 which prevents any radiation reaching free space other than after reflection by the reflector. The shield. extends between the two most central plates 5 and is shaped as shown in Fig. 2 so as also to contain an auxiliary radiator 7. None of the energy from radiator 7 can reach the cheese reflector and it is all directed outwardly to fill in the dip in the radiation pattern which would otherwise be present due to the obstruction caused by the presence of the elements 6 and 7 and the shield 10 in the reflector aperture. The feeders 8 and 9 from the two elements 6 and 7 are taken to the same radio apparatus. The connection to feeder 9 conveniently contains means for adjusting the phase and amplitude of the signals to the correct value.

Abstract: 373,931. Gravity-separa,tion apparatus. DORR CO., Inc., 247, Park Avenue, New York, U.S.A. Nov. 16, 1931, No. 31669. Convention date, Nov. 25, 1930. [Class 46.] The scum in a settling tank is collected by a rotating baffle against a scoop which moves horizontally to eject it over a weir into a scumdischarge chamber. The material under treatment is supplied to the settling tank 10, Figs. 1 and 2, from a channel 32 through an opening 36 behind a baffle 37, the outer wall 33 of the channel 32 constituting a weir. The effluent liquid leaves through a slot 38 and passes over a weir 39 to a channel 40. Settled sludge is collected to a gutter 12 by rakes 19 supported by arms 17 attached to a drum 16 rotating on a central column 13. The drum 16 is rotated by means of a truss 21, the outer end of which is supported on a wheel 22 which is driven on a rail 23 surrounding the tank by an electric motor 24. An auxiliary blade 28 supported from the truss 21 collects settled matter from the corners of the base. The truss 21 carries a baffle 42 which collects the scum as it rotates and directs it towards a sweep 54. The sweep 54 is pivoted at its outer end and drawn by a weighted chain 56 so that its inner end engages the baffle 42, which extends around the truss and is curved at the inner end. The arrangement is such that as the baffle 42 approaches the sweep 54 and collects scum in the space between them, the sweep 54 is closed against the side of the tank and forces scum through an adjustable slot in the wall into a chamber 45. The sweep 54 closes the slot while the baffle 42 is passing and during this time valves in base of the chamber 45 are automatically opened so that the scum is discharged without loss of liquid. Fig. 4 shows modified apparatus in which curved sweeps 54a operated by a rotary baffle 42a in the manner described above force out scum into discharge chambers 85 at the corners of the tank.

Title: Improvements in or relating to means for recording or indicating the flow of water in open or covered-in channels
IPC: G01F1/00
Filed: 1923-12-19
Abstract: 230,562. Puccioni, C. Dec. 19, 1923. Recording by co-ordinates.- Apparatus for measuring and recording the flow of water in open or covered channels comprises a float carrying a blade in such a manner that the level of the float controls the depth of immersion of the blade, so that the latter is acted on by the water having the greatest velocity; the movements of the blade and of the float are transmitted to apparatus, where they cause displacements proportional to the maximum velocitv and cross-sectional area of the channel, the firstmentioned displacement being converted into one proportional to the mean velocity, and a final displacement being obtained proportional to the product of the mean velocity and the sectional area of the channel. Integrating apparatus of known form is also employed. The float G, Fig. 1, is pivotally connected at D to a frame T secured to a horizontal axle B adapted to rotate in a fixed casing. As the float rises and falls with changes in water level, a roller on a lever BC acts on the under-surface of a bracket secured to a vertical rod e, Fig. 3, to reciprocate a carriage 1, the bracket being shaped in accordance with the shape of the water channel so that the carriage indicates the cross-sectional area of the channel on a scale 6. The blade P is adjustably secured to an arm P‹ carried bv a sleeve A‹ rotatable about an axle A carried by the frame T, and its deviation is transmitted by a parallelogram connection to a sleeve mounted on the axle B. By means of a sector R, Fig. 5, pinion r, and chainconnected pinions R<1>, r<1>. a cylinder F<1> is oscillated. On the cylinder is a cam consisting of a wire F<2>, which causes movement of a slider V<1> to indicate the maximum velocities on a scale 4, and to oscillate a pivoted link S‹, V<2>. The link operates a slider Vm<1> to indicate the mean velocities on a scale 5, and a slider Q<1> supported on the carriage I to indicate the quantity of water flowing per second. This quantity is recorded on a drum R<2> by a stylus R<3>, the stylus being carried by a rod OO<1>, Fig. 4, connecting parallel levers H<1>O<1>, HOM, the lever HOM forming part of a parallelogram HKLM, the side LM of which is operatively connected to the slides Q<1>, and a connection to integrating apparatus being made at Mo. Where the water channel is of such character that the ratio between the mean and maximum velocities varies with changes in the water level, the cylinder F<1> and the guide for the slider V<1> are carried by rods TT<1>, forming part of parallelograms so that they are vertically adjusted by lever and cam means from the carriage I.
