Title: Improvements relating to machines for topping sugar beets in the ground
IPC: A01D23/02
Filed: 1936-12-01
Abstract: 486,314. Topping beetroots. CATCHPOLE, W. M. Dec. 1, 1936, No. 32990. [Class 6 (iii)] A beet-topping machine comprises a wheeled frame 1 carrying by means of parallel links 6, 7, 8, 9, a floating frame or track unit 10 comprising an endless track of wooden slats 11 mounted at their ends on endless chains 12 that pass round rollers or sprockets on the floating frame and one pair of which is driven through chain and sprocket gearing from one of the axles so that the track moves rearwardlv at the same rate as the machine moves forwardly : two disc cutters 17, 18 carried by vertical shafts adjustable in the floating frame cut off the tops of the beet just below the track, The track is provided with a central raised portion that engages the crown of each beet and positions the floating frame just before the knives engage the beet; the leaves are pushed to the sides of this raised portion which is provided with spikes 24 to hold each root against the thrust of the knives. To assist this holding action the speed of the track may be slightly greater than the speed of the machine. The track unit and the knives may be driven from the power shaft of a tractor or from a motor on the machine.
Patent GB-466510-A (GB)
Title: Improvements in or relating to the production of paraffin wax emulsions
IPC: D21H17/60
Filed: 1935-11-29
Abstract: Aqueous emulsions of paraffin wax are obtained by heating paraffin wax with an emulsifying wax such as esparto wax, wool wax and Montax wax, and a preformed 10 per cent rosin soap solution, the total amount of water present during emulsification being between 20 per cent and 50 per cent of the weight of the mixture and the emulsification being carried out without the use of colloid mills or high speed stirring apparatus.  For example, 64 kgm. of paraffin wax, 26 kgm. esparto wax and 110 litres of 10 per cent rosin soap solution are boiled together for about 45 minutes. The resulting emulsion may be diluted with water.  Other materials may be added, e.g. starch and animal glue, fungicides or colouring matters, either during the emulsification of wax or added as emulsions to the wax emulsion.  The products may be used for beater- and surface-sizing of paper and paper pulp and for impregnating and coating porous materials such as paper, wood or stone.  Specification 28178/10, [Class 95], is referred to.

A winch drum is mounted on a gear wheel engaging a fixed gear and journalled on an eccentric on a driving shaft, whereby a self sustaining effect is obtained once during each revolution of the drum. Fig. 1. A handle at 10 drives shaft 7 which, by means of eccentrics 11 and 12 fixed thereon, gives a rolling motion to drum 18 mounted on the said eccentrics. The drum 18 has internal gears 16 and 17, and the latter roll around gears 4 and 5 fixed to casing 1 so that the drum is driven with a slow differential movement. The wire 19 is wound round the drum 18 and its end is fixed to eye 21 on the casing, the load to be raised being held in the bight of the wire. When the handle is released the drum turns till it reaches a self-locking position. Fig. 4. Drum 48 is similarly driven differentially by handle 46 through shaft 45 and eccentric 47, the drum having internal gears 49 and 50 co-operating with gears 43 and 44 fixed on casing 41. The wire 51 passes from the load (e.g., car to be hauled) and round the drum, the coils being kept tight by roll 52 mounted on frame 53, the frame floating on spring 54 operated by pin 55.

Title: Process for the manufacture of compounds of the androstane and pregnane series
Filed: 1936-12-05
Abstract: Unsaturated compounds of the androstane and pregnane series containing at least two oxygen atoms attached to the ring carbon atoms are prepared by subjecting unsaturated compounds of the androstane or pregnane series which contain at least one hydroxyl group or esters thereof to the action of agents which split off water or acid.  Suitable unsaturated parent materials may be obtained according to Specification 486,854.  The preferred method of removal of water or acid is by the action of heat.  In the cases where the hydroxyl group to be split off is esterified with halogen hydride, the splitting agent may be an alkaline material such as pyridine, or quinoline.  Starting materials mentioned are D 5-androstentriol-3-7-17, and its esters such as the tri-benzoate, which may be obtained by reduction of D 5-7-oxo - androstendiol - 3 : 17 or of D 5 - 7 - oxoandrostenol-3-one-17.  In examples: (1) D 5-androstentriol - tribenzoate - 3 - 7 - 17 is subjected to vacuum distillation and the distillate recrystallized from alcohol; (2) D 5 - 7 - oxoandrostendiol-3 : 17-diacetate is boiled with caustic potash for 20 minutes, diluted with water and worked up to give D 3-D 5-androstandienol-17-one-7.

Title: Automatic tuning device
IPC: H03J7/26
Filed: 1968-07-25
Abstract: 1,241,562. Automatic tuning arrangements. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 25 July, 1968 [25 July, 1967 (2); 3 April, 1968 (4); 4 April, 1968; 5 April, 1968], No. 33697/68. Heading H3Q. In an automatic tuning arrangement employing purely electrically controlled variable reactance elements a mixer is provided for mixing an output from the local oscillator with a multiplicity of fixed reference frequency oscillations and automatic frequency control means maintains constant the mixer output frequency thereby controlling the reactance of each variable reactance element and determining the tuning. In an embodiment comprising a receiver with stages 2-6 and 8, voltage variable reactances in the H.F. circuit 2 and local oscillator 8 are controlled by the voltage across capacitor 15, via amplifier 20. The tuning is swept over the tuning range by means of sweeping circuit 19 the output of which is coupled to capacitor 15 via gate circuit 18, tuning being initiated by means of sweep start switch 16. Upon interception, a signal passing narrow band I.F. filter 9 to detector 10 causes reversal of bi-stable circuit 17, which closes gate 18 and so disconnects charging source 19 from capacitor 15. To prevent tuning drift, more especially in the case of fading or temporary cessation of the signal, a control voltage is applied to capacitor 15 from a controlling circuit 14, comprising a frequency discriminator and D.C. control circuit. Controlling circuit 14 derives an input from mixer 12 via filter 13; the inputs to mixer 12 comprise (i) an output from local oscillator 8 and (ii) the output of oscillator circuit 11 which comprises harmonics, from a 10 Kc. oscillator and harmonic generator, these harmonics being spaced 10 Kcs. apart i.e. the spacing of signals in the broadcast band. The Specification also discloses numerous alternative arrangements, including some in which automatic frequency control dependent upon the signal is also used: sweep control, automatic frequency control dependent upon the signal and automatic control dependent upon harmonics of a local oscillator may be brought into operation successively each control being rendered ineffective while a preceding control is operative.
