Title: Improvements in or relating to means for delivering material in quantities of predetermined weight
IPC: G01G13/00
Filed: 1934-03-08
Abstract: 434,501. Weighing-apparatus. SUTTON, G. J., 14, Victoria Street, Westminster. March 8, 1934, No. 3822/33. [Class 143] A machine for weighing out tobacco or other fibrous material by a system of adding approximate doses to the scale pan comprises a plurality of weighing scales and pincer-like blades associated with each weighing scale adapted to pick up a dose of the material from a supply and deliver the dose automatically to the scale pan if the quantity of material already in the scale pan is less than a predetermined amount. As applied to a tobacco weighing machine, a series of carriers 18, pivotally supporting cans 22 (one only shown), are pushed along a gapped guide rail 13, step by step, by means of vertical arms 15 on an intermittently moving chain 14. The cans are thus pushed successively on to scale beams 32 (one only shown), situated in the gaps at the stopping stations A, B, C, &c., a slight retrograde movement being given to the chain at the stopping stations to withdraw the propelling arms 15 from the cans. The cans arrive at the first weighing station A with the major portion of the charge previously inserted. Predetermined additions or doses, contained in hoppers 50, decreasing in amount in successive hoppers, are made to the cans at the successive stations, provided the deficits are great enough to leave the scale beams undisturbed when liberated for weighing. The hoppers 50 are replenished as described below by means of pincers 55. After passing the weighing stations the cans are emptied, for example by a ramp which tilts the cans, to eject their contents down a shoot. The scale beams are secured against movement prior to weighing, by means of stops 44 which are withdrawn by cam action for the weighing operation. The additional charges or doses in the hoppers 50 are dumped into the cans by means of cam-operated arms 65, hooks 64 and spring-pressed sliding bars 53 which liberate the delivery gates 51 of the hoppers. If, however, the weight of tobacco in the can is sufficient to tilt a scale beam 32 a projection 70 thereon raises the actuating hook from the sliding bar and prevents the addition at that station. When the sliding bar reciprocates after a dumping operation, the pincers 55 convey a new charge of tobacco from a container 12 to the hopper 50.

Title: Method for converting iron sulphate heptahydrate into iron sulfate monohydrate
IPC: C01G49/14
Filed: 1965-02-01
Abstract: FeSO4.H2O is prepared by continuously supplying a hot aqueous crystal-free saturated solution of FeSO4.7H2O to a crystallizer, and supplying heat thereto to maintain a temperature at which solid FeSO4.H2O is stable in contact with a saturated solution of FeSO4.7H2O, continuously removing the liquor containing solid FeSO4.H2O and separating it therefrom. The mother liquor may be recycled to the crystallizer, which may be that disclosed in Specification 1,090,022.  The temperature in the crystallizer may be maintained by passing the liquors therein over a heating element, the temperature difference of the entering and exiting liquors passing thereover being 0.5-2.0 DEG  C.  A part of the crystal-free liquor in the crystallizer may be withdrawn and worked up to recover FeSO4.7H2O which is recycled to prepare further saturated solution thereof, or the crystal-free liquor may be used to dissolve further FeSO4.7H2O to form the saturated solution.

Abstract: 433,224. Rotary kilns. FASTING, J. S., 9, Monrads Alle, Copenhagen. Feb. 12, 1934, No. 4668. [Class 51 (ii)] In a rotary cement kiln having in the drying and preheating zones groups of heat-transmitting elements, such as chains 7, 7<1>, in contact with which the gases flow in series, the charge is divided into separate streams each stream contacting with one group only of the heat-transmitting elements, and all the streams being united to flow through the hotter zones of the kiln. In the construction shown in Fig. 1, slurry is supplied by the shoot 2, and by scoops 5 through inlets 3. Both streams of slurry flow from left to right, and that which contacts with the chains 7 is stopped by the ring 6 and passed through the aperture 8 to the annular space 13 around the next section of the kiln. In a modification, Fig. 2 (not shown), the slurry flows from right to left in contact with the chains 7<1> and the two streams unite between the two groups of chains. In another form, Fig. 3, the two streams of the charge are supplied through the shoot 2 and pipe 9, and transfer to the main body of the kiln below the stop ring 6 is effected through external ducts 13, 12. In a further modification, Fig. 4 (not shown), the second portion of the charge is supplied to both ends of the chain group 7<1>, and the transfer duct 12 leads from the middle of the length of the lower chain zone. In another form, Fig. 6, in which the heat-transmitting elements consist of radial partitions in casings 15 the portion of the charge for the lower casing 15 is fed through the shoot 21 and the annular space around the upper casing, while that portion supplied through the shoot 2 passes through the upper casing and the annular space around the lower casing. One or both sets of heat-transmitting elements may be in a separate drum.

Title: Clipper circuits and method of clipping
IPC: H04N5/213
Filed: 1965-02-03
Abstract: 1,105,661. Field effect transistor clipper circuit; television synch, signal separator. RADIO CORPORATION OF AMERICA. 3 Feb., 1965 [12 Feb., 1964], No. 4704/65. Headings H3T and H4F. A method of clipping an input signal to obtain an output signal comprises applying an input signal between the source and gate of an insulated gate field effect transistor and applying a control signal to bias the transistor at a level above which the input signal causes the transistor to conduct to obtain an output signal which corresponds to the portion of the input signal that exceeds the bias level. A clipper circuit for carrying out this method may be used as a noise inverter 200 and as a synch. separator 205 for separating the horizontal and vertical synch. pulses from the picture signal in a television receiver as shown. The transistor 50 is biased by an A.G.C. voltage 218 so that any noise occurring on the picture signal from the output of the video amplifier 210 is inverted at the output drain electrode 56. This inverted noise signal is applied via a capacitor 60 to the input of the synch. separator transistor 80 together with the picture signal from the video amplifier 210 applied across the terminals t, t<SP>1</SP> so that the noise signal is eliminated. The video signal is coupled via a resistor 84 and capacitor 87 to the substrate electrode 108 of the field offset transistor 80 so that the rectifier diode (110, Fig. 8, not shown) between the substrate electrode and the source electrode biases the gate 76 at a value such that the synch. pulses are aligned at this potential level. The resistor 84 may be connected to a tapping point on the resistor 70. In an alternative synch separator circuit (Fig. 9, not shown), an additional short time constant R.-C. circuit (88, 90) is connected between the point b and capacitor 87 and a diode (82) is connected in parallel with the resistor 93 in place of the substrate diode connection. In a simplified clipper circuit (Fig. 4, not shown), the input signal (49) is applied to the source electrode and the control voltage which may be an A.G.C. voltage (V3) is applied to the gate electrode (44). Similar synch. separator and limiter circuits are described in Specification 1,043,124. Reference has been directed by the Comptroller to Specification 1,043,124.
