Title: Improvements in or relating to method of producing vitamin-containing fodder lime preparations
Filed: 1946-05-17
Abstract: A vitamin-containing fodder lime preparation is obtained by saturating an absorbent with a solution of a vitamin particularly an oily solution of a vitamin, incorporating with the mixture of absorbent and vitamin a solution of an alkyl cellulose, especially methyl cellulose, granulating and drying the resulting mixture to produce granules provided with a protective coating of alkyl cellulose, and incorporating the resultant granules with the mineral basic substances of the fodder lime preparation. Preferably, substances adapted to increase the wetting action, such as water glass or other soluble salts of bivalent or polyvalent acids, are added to the alkyl cellulose solution. According to an example, lucerne meal is kneaded with an oily solution of vitamin D and then saturated with a 5 per cent methyl cellulose solution to which water glass solution has been added. The mixture is granulated and dried at a temperature preferably not exceeding 50 DEG  C.  This granulate is mixed with feed lime and with other admixtures.  Other specified absorbents are camomile, milfoil or milled fruits such as meal of anise, fennel, juniper berries, meal of calamus radix, or animal charcoal.ALSO:A vitamin-containing fodder lime preparation is obtained by saturating an absorbent with a solution of a vitamin particularly an oily solution of a vitamin, incorporating with the mixture of absorbent and vitamin a solution of an alkyl cellulose, especially methyl cellulose, granulating and drying the resulting mixture to produce granules provided with a protective coating of alkyl cellulose, and incorporating the resultant granules with the mineral basic substances of the fodder lime preparation.

Title: Ultrasonic transducers

Abstract: 990, 702. Measuring phase differences. G. A. D. GORDON. April 11, 1963 [April 18, 1962], No. 15121/62. Heading G1U. [Also in Divisions H3 and H4] In an ultrasonic transducer including a piezoelectric crystal having drive electrodes and at least one additional electrode, the additional electrode being arranged to supply a monitoring potential, means are provided for detecting any phase difference between the exciting voltage and the monitoring potential. The arrangement enables the circuit to be adjusted for maximum power output from the transducer. As shown, the drive electrodes are supplied from an R.F. source which is also supplied via an amplifier or attenuator and a phase shift network to one deflector plate of a cathode ray tube. The monitoring potential is supplied via a similar amplifier or attentuator and phase shift network to the other deflector plate. The phase shift networks are adjusted so that at the frequency giving maximum power the potentials of the deflector plates are in phase so that the Lissajou figure appears as a straight line. As the exciting potential passes through resonance the relative phases of the drive electrodes and the additional electrode change and this change may be used to control the frequency of the energizing voltage automatically via monitoring control apparatus as indicated to give maximum power output.

Title: Improvements in or relating to electric control systems for fuel burners
IPC: F23N5/10
Filed: 1948-06-04
Abstract: 654,703. Automatic temperature control systems. ROBERTSHAW - FULTON CONTROLS CO. June 4, 1948, No. 15174. [Class 38 (iv)] [Also in Groups XI and XXXVII] A thermostat controlling the operation of a burner apparatus comprises a bi-metallic spiral 64 actuated by the temperature of the room being heated and having a movable arm 66 carrying two spaced contacts 72, 74 controlling the electric circuit to an electrically-operated fuel valve 16 for the main burner. A third contact 84 is secured to the movable arm 66 but is insulated therefrom and co-operates with a third fixed contact 86 to control inter alia the circuit to an electrically-operated fuel valve 23 for the pilot burner. The contacts make in sequence 84, 70, 68 and break in reverse sequence and in the open position of the main burner fuel valve its armature 25 makes a contact 21 to connect a resistor 76 in parallel with the contact pair 68, 72 so that when these contacts open, on a demand for heat being satisfied, the resistor 76 is energized to heat the bimetallic spiral 64 and thereby accelerate the opening of the other two contact pairs. In order to vary the temperature at which the contacts on the arm 66 engage with the fixed contacts the bimetallic spiral is pivotally adjusted by a lever arm 78 which indicates the temperature setting on a fixed scale 82. When, however, the lever arm 78 is moved to the extreme left of the scale the movable arm 66 opens a toggle switch 88 in series with the contact pair 84, 86 so that the pilot burner fuel valve 23 is closed and is no longer controlled by the contacts 84, 86. The contacts 84, 86 may be bridged by a wire AB to remove the control of the arm 66 on the pilot burner fuel valve. Specification 601,739, [Group XI], is referred to.

Title: Improvements in or relating to Vacuum Feed Systems for Liquids.
Inventor: JAY WEBB
IPC: F02M37/02
Filed: 1916-10-25
Abstract: 110,593. Jay, W. Oct. 25, 1916. Vacuum apparatus.-In apparatus for raising liquids from one receptacle to another, such as is used for raising liquid fuel for an internal-combustion engine from a reservoir to a chamber which feeds the carburettor, a supplementary chamber 3 is provided in which atmospheric pressure and vacuum alternate, the change from one condition to the other being effected by the overflow of liquid from the higher chamber 4. The chamber 3 is preferably mounted on the liquid reservoir 1, and is connected by a pipe 14 to the chamber 4, and by a pipe 13 to a source of suction. The air-valve 11 is opened by a lever 20 when a receiver 22 on one end of the lever is filled with the overflow from the chamber 4. The receiver 22 has a small hole 22<a> through which the liquid flows into the chamber 3 and thence through the valved pipe 16 to the reservoir. The reservoir is connected to the chamber 4 by a pipe 9 which passes through the chamber 3. The suction aperture 12a is relatively small, so that, when the valve 11 opens, the vacuum in the chamber 3 and 4 is destroyed and the liquid in the chamber 4 flows through a valved pipe 6 into an auxiliary chamber 5 which feeds the carburettor &c. The opening and closing of the valve 11 is given a snap action by spring 25 &c. In a modification, the springs 25 &c. are omitted and the area of the valve 11 is such that the suction holds it on its seat until the receiver 22 is filled, when it opens suddenly. In another form, the valve 11 is opened by a float which actuates a lever connected to the valve when liquid overflows from the chamber 4 to the chamber 3. The level of liquid in the 'tank 1 may be indicated by a pointer adapted to be moved over a scale on the outer surface of the chamber 3 by a lever connected to float in the tank.

The power dissipation in a resistor R is maintained constant with variation of its resistance due to rise in temperature by feeding R through a constant current network LC from a stabilized voltage source and a potentiometer P1, the voltage drop across R being compared with that across a similarly connected resistor R1, any difference causing a servomotor to adjust R1 and the sliders of potentiometers P1, P2 until balance is regained. It is shown that if the potentiometers P1, P2 and resistor R1 are wound so that the power dissipation in R is constant. The network may be used in conjunction with the measurement of the thermal conductivity of a liquid.
