Patent GB-1110274-A (GB)
Title: Improvements in and relating to washing and/or grading machines primarily for vegetables
Inventor: HAITH GEORGE GEOFFREY
IPC: B03B11/00
Filed: 1965-06-29
Abstract: 1,110,274. Sink-and-float apparatus. HAITH ENGINEERS Ltd. 27 Sept., 1966 [29 June, 1965], No. 27415/65. Heading B2H. Apparatus 20, Fig. 1, for separating into its constituents a mixture of produce and waste by flotation in a liquid, comprises a liquid tank 22 and separate produce and waste conveyors 28, 29 extending from below a predetermined level in the tank to positions above that level, the produce conveyor 28 being perforate. A partition, 33, Fig. 3, presents produce, e.g. carrots, floating in liquid in the tank from being lifted from the liquid by the waste conveyor 29. Further, large waste is prevented from getting on to the conveyor 29 by the partition 33, and a baffle plate 32 prevents waste getting on to the produce conveyor 28. A wall 25 divides the tank into a separating compartment 26 and a cleaning compartment 27 from which access to the separating compartment can be obtained below the wall 25 to permit waste to be removed therefrom. An impeller 34 causes an upper layer of the liquid to flow towards the produce conveyor to deposit floating produce thereon. In operation, the mixture is fed from a hopper 10 along a conveyor 11 to a rotary grading screen 12, from the open end of which large stones and large produce are fed by a conveyor 21 for hand-sorting. The rotary screen 12 is driven by rollers 18 and chains 19, and discharges three piles of waste on a floor below its three forward sections 14. The last section 14 is above the apparatus 20. Waste sinks in the bank 22 and is carried away by the conveyor 29. Produce is removed by the conveyor 28 the liquid draining through the conveyor perforations back to the tank. At the upper end of the produce conveyor 28 a chute 36 directs the produce on to a conveyor 37 which directs the produce to a second screen 38. Graded produce leaves the third and fourth sections 39, via conveyors 40, 41. The open end of the screen 38 feeds larger produce to a conveyor 42 which delivers the produce to a bagging station (not shown).

Title: Improvements relating to weighing apparatus
Inventor: TERRY FRANCIS SIEVWRIGHT
IPC: G01G13/00
Filed: 1962-07-18
Abstract: 1,007,795. Automatic feed weighers. W. & T. AVERY Ltd. July 12, 1963 [July 18, 1962], No. 27520/62. Heading G1W. In an automatic feed weigher pulverulent material in a duct 2 (Fig. 1) is fluidized by air under pressure admitted at a connection 3a to a space 3 beneath a porous floor 4, so that the material flows to a duct outlet which is controlled by a slide gate and thence to a weigh receptacle 17 supported on a steelyard 15. The slide gate has a slide 7 horizontally reciprocable by means of a hydraulic ram 8. Depending on the inclination of the steelyard the slide 7 is automatically positioned to provide either a full feed (Fig. 2 not shown), a dribble feed through a small aperture 7a (Fig. 3) or to cut off the feed (Fig. 4 not shown). The steelyard has counterweights 10 and means for controlling the slide gate including a boost lever 13 for giving a thrust partially counterbalancing the leverage of the counterweights 10 and microswitches 11, 12. In operation when the weight of material in the receptacle reaches a predetermined value a little short of the required value the rise of the left arm of the steelyard operates the micro-switch 12 which is arranged (by means not described) to actuate the ram 8 which then moves the slide 7 to the dribble feed position, and at the same time the boost lever 13 ceases to apply a thrust on the steelyard. The dribble feed continues until the weigh receptacle has received the required weight and, with due allowance for material "in suspension", the micro-switch 11 is operated by the steelyard whereby the ram closes the slide gate and simultaneously the fluidizing air supply is cut-off.

Title: Means for mutually levelling contiguous vehicles with pneumatic suspension in a road train
IPC: B60G17/033

Abstract: 968,369. Adjusting relative height of vehicles. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. July 18, 1962 [July 19, 1961], No. 27548/62. Heading B7D. The relative height of two vehicles A, B with pneumatic suspension, connected by a towbar C is controlled by a levelling device H mounted on one vehicle and connected by link H 1  to the other vehicle which adjusts the air pressure in the springs of one vehicle when the relative height changes. The levelling system is arranged so that the levelling device H and levelling devices A3, B3 of the two vehicles may not operate at the same time. The levelling devices A3, B3 are only brought into operation when manual switch I2 or automatic switch I1 is closed, operating electromagnetic valve F to permit air to flow from compressed air tank D to the levelling devices A3, B3. Automatic switch I1 preferably only closes when the vehicle is stationary and the doors are open. Each device A3, B3 includes a levelling valve and a pneumatically controlled cam or rocker which operatively connects the linkage A4, B4 to the levelling valve only when the device is supplied with air through valve F. Depression of switch K closes valve F and opens electromagnetic valve G to supply levelling device H only with air and thus adjust the relative height of the vehicles A, B. Specifications 841,006 and 876,165 are referred to.

Title: Improvements in or relating to the removal of fluorine form acid nitrate-containing solutions
IPC: C05B11/06
Filed: 1946-09-16
Abstract: Fluorine-containing compounds are removed from acid nitrate-containing solutions in particular as obtained by decomposing phosphates with nitric acid by treatment continuously with a counter current of steam.  The vapour mixture is preferably separated at 120-140 DEG  C.  The calcium nitrate concentration should be low, e.g. by carrying out the distillation after the crystallization of calcium nitrate, or by adding a calcium nitrate solution of lower concentration.  One portion of the purified solution, after separation of some of its calcium nitrate content, may be recycled to the phosphate-decomposition stage, and another portion neutralized, e.g. with ammonia if necessary after the addition of nitric acid. Alternatively, only the latter portion need be purified.  The distillation may be effected by the steam developed during neutralization.  If the phosphate does not contain sufficient silica for the formation of silicon fluoride, sand, &c. may be added; alternatively, the precipitate separated from the distillate may be used.  Reference is made to the use of a distillation column fitted with Raschig rings.

Title: Improvements in or relating to ultrasonic device for measuring the thickness of objects
IPC: G01B17/02
Filed: 1952-11-07
Abstract: 714,031. Ultrasonic inspection devices. SPERRY PRODUCTS, Inc. Nov. 7, 1952 [Dec. 7, 1951], No. 28101/52., Class 118 (2). A device for determining the thickness of an object comprises an electro-acoustic transducer for transmitting ultrosonic vibrations into the object through one surface thereof at an angle to the normal, and a second transducer for receiving said vibrations after reflection from the opposite surface of the object, with means for moving the receiving transducer relative to the transmitting transducer to locate the point of maximum energy reception and means for indicating the distance between the transducers. A quartz crystal 15 is. mounted on a support 16 at an angle # to the surface 11 of an object 10 whose thickness is to be measured. An electric oscillator 20, fed from power supply 21, continuously energizes crystal 15 to emit an ultrasonic beam B which after reflection at the surface 12 is intercepted by another quartz crystal 15<SP>1</SP> mounted on a support 16<SP>1</SP> at the same angle as crystal 15 but in the opposite direction. Crystal 15<SP>1</SP> is connected to an amplifier 37 and may be moved relative to crystal 15 by rotating knob 31 on the screwed rod 30 which is in threaded engagement with lug 32 on support 16 and freely rotatable in lug 33 on support 16'. The crystal spacing is varied until maximum pick-up is indicated by earphones 35 and/or meter 36. It is shown that T=kL where T=thickness of the object, L=the distance between the points where the beam enters and leaves the object, and k is a constant depending upon angle #. Thus a rod 40 fixed to lug 33 and slidable in lug 32 may carry a scale giving a direct reading of object thickness. If the acoustic impedance of the material supports 16, 16<SP>1</SP> is not the same as that of object 10 the beam B will undergo refraction on entering and leaving the object 10, Fig. 3 (not shown), and this will change the value of k in the formula T=kL and affect the calibration of rod 40.
