Title: Improvements in or relating to mixing machines
IPC: B01F9/10
Filed: 1959-07-17
Abstract: 866,655. Cement mixers. LARSON, K. O. July 17, 1959 [Aug. 7, 1958], No. 24646/59. Class 86 A portable cement mixer has a drum 12 (which may be a 5 gallon paint container having a bail handle 13) removably received in members 10, 14 mounted on a turntable 9 having a socket 8 to receive a spindle 7 fixed to a take-apart frame 1. An electric motor 25 has a base plate 26 having a hole which engages with a stud 27 on the frame, and an adjustable ratchet 28, 29. The motor drives a pulley assembly 19 mounted for rotation on one end of a lever 22 which is pivoted at 23 on the frame and carrier on the other end a rotatable and extensible mixer arm 35 having a blade 43. The pulley assembly 19 rotates the drum 12 and turntable 9 by a link chain 17 entrained round a sprocket 16. The action of the materials on the blade 43 brings its edge 44 into scraping contact with the carrier wall of the drum, see Fig. 4 (not shown); its bottom edge is in contact under gravity with the bottom of the drum. The pivotted lever 22 tends to maintain the link chain 17 taut in operation due is the drag of the materials on the mixing arm.

Title: Improvements in or relating to electronic balancing apparatus
IPC: G01M1/22
Filed: 1952-10-02
Abstract: 737,795. Electric indicating systems. GENERAL ELECTRIC CO., Ltd., and SMART, A. T. Oct. 2, 1953 [Oct. 2, 1952], No. 24727/52. Class 40 (1).  The invention relates to electronic balancing machines in which an indication of the phase position of unbalance of a rotor relative to a reference position on the rotor is effected electrically. Unsteadiness of the indication, caused by a random phase variation of the mechanical vibration of the rotor, is, according to the invention overcome by passing the electric signal indicative of the " phase " of the unbalance through a network which produces a "steady" signal responsive to the mean phase of the signal but unresponsive to more rapid random changes in the phase of the signal. Preferably, the steady signal is produced by an oscillator whose frequency is controlled in dependance on the phase of the input signal by a circuit having a relatively long time constant so that the phase of the oscillator output varies only with the mean phase of the input. As shown, the input signal applied at 10-11 is clipped at 13-18 to rectangular waveform, amplified in the left-hand triode of a tube 20 and fed to one diagonal of a rectifier bridge phase discriminator 31-34, the other diagonal 46-47 of which is fed from a multivibratortype oscillator 60 through a transformer 44. The bridge D.C. output, proportional to the phase difference between the amplified input signal and the " steady" signal from the oscillator, is smoothed, and amplified in the right-hand portion of valve 20, the output of which controls the conductance of the left-hand triode 50. The control grids of the oscillator 60 are both biased in dependence on the conductance of this tube through a relatively long time constant circuit so that the oscillator frequency can only respond to relatively slow variations of phase of the input signal. The " steady " output signal taken from point 70 is applied to the unbalance " phase " position indicator, e.g. a stroboscopic indicator. Specification 610,705 is referred to.

Title: Improvements in or relating to agricultural spray materials
IPC: A01N41/02
Filed: 1954-08-27
Abstract: Thiosulphates of aliphatic hydrocarbons and oxahydrocarbons may be obtained by refluxing organic mono- and polyhalides with water-soluble inorganic thiosulphates.  The reaction products may be blended with alkali or alkaline earth sulphides, polysulphides and sulphydrates for use in agricultural sprays (see Group VI). In an example (I) bis-(b -chloroethyl) ether is refluxed at 95-120 DEG  C. with sodium thiosulphate pentahydrate in water. Evaporation to dryness yields a mixture of the dithiosulphates, together with sodium chloride and unreacted sodium thiosulphate. In Example 7 the preparation of a dithiosulphate from ethylene dichloride is described.ALSO:A solid dry composition for use with insecticides, fungicides and phytotoxins as an agricultural spray comprises one or more thiosulphates of aliphatic hydrocarbons and oxahydrocarbons, each molecule of said thiosulphates having at least one S2O3Na radical attached to a carbon atom and at least one major proportion of said compounds having at least one S2O3Na radical attached to each of different carbon atoms of the hydrocarbon or oxa-hydrocarbon chain structure and a reagent selected from the group of alkali or alkaline earth metal sulphides, polysulphides and sulphydrates.  On adding to water the compounds react to form a latex which prevents the insecticide &c. from being removed from the foliage by the action of the weather.  The insecticide may be added to the composition or the composition sprayed on to the insecticide-treated foliage. Conventional insecticides, fungicides, phytotoxins &c. may be used such as D.D.T., Lindane (g -hexachloro - cyclohexane) 2 - (p - tert - butylphenoxy) - isopropyl - 2 - chloro-ethyl sulphite, ferric dimethyldithiocarbamate, sulphur and 2,4D (isopropyl- -2,4 - dichlorophenoxy-acetate).  Wetting agents (many specified) may be added to the composition: liquid wetting agents may be mixed with a carrier such as bentonite prior to blending into the composition.  In an example a mixture of dithiosulphates derived from bis - (b  - chloroethyl) ether is blended with commercial calcium polysulphide.

Title: Improvements in fluid depth sensing apparatus
IPC: G01F23/26
Filed: 1962-07-03
Abstract: 1,015,852. Electric selective signalling. TRANS-SONICS Inc. July 3, 1962 [July 3, 1961], No. 25496/62. Heading G4H. [Also in Division G1] A liquid level measuring apparatus comprises a number of transducers mounted such that the level is given in monophylic code, e.g. Gray code. The Gray code output is converted to binary code by relays and the binary code is converted to the analogue value, which feeds a meter. The transducers are transformers or capacitors which provide an output when they are immersed. Transformer transducers are formed by windings on spaced cores (see Heading G1N). When immersed in a conducting liquid the secondary is magnetically coupled with the primary. In the case of a non-conducting liquid, the cores are linked by a conducting loop which is temperature sensitive, so that there is a sharp change in secondary voltage when the transducer is immersed. To provide a coarse check on the correct operation of the apparatus, extra transducers are used to give an approximate indication of the liquid level. If the apparatus is calibrated in terms of volume, the transducers will be non-linearly spaced if the liquid container is irregular.
