Title: Improvements in or relating to methods and apparatus for sorting small articles such as seeds and the like
IPC: B07C5/342
Filed: 1946-07-03
Abstract: 617,276. Sorting small articles. OKOLICSANYI, F., and GUNSON (SEEDS), Ltd., R. W. July 3, 1946, No. 19920. [Class 40 (iii)] In a device for sorting small articles according to their colour or degree of darkness, beans, for example, fall one at a time over the metallic end of an insulated chute 14, this end constituting an electrode. As each passes the end it reflects light from a source 21 on to a photo-cell 24. This cell then controls a circuit which alters the potential of the metallic tip of the chute according to the amount of light received so that the bean is charged to a certain potential and in passing between plates 12 and 13 oppositely charged to a high potential, according to its darkness falls direct into a pan 19 or is deflected into a pan 20. A colour filter may be inserted between the light source and the photo-cell or magnetic deflection may be used. Circuit arrangements.-The deflector plates 12 and 13 are fed from opposite corners 36, 37 of a voltage doubling rectifier bridge fed from a transformer 31. The potential of the chute tip 14 is controlled by the photo-cell 24. When this cell receives reflected light from a light beam it conducts, the resulting flow of current in a resistor 51 reducing the bias on the grid of the valve 45, which also conducts, the change in its anode potential being used to block a further valve 55. The anode of this valve is connected to the positive supply to the deflector plate 12 through a relatively low resistance 57, direct to the tip of the chute 14 and through a very high resistance 58 to earth. When the valve blocks the chute tip 14 is substantially at the potential of the deflector plate 12 and the bean is thus deflected into pan 20. If insufficient light falls on photocell 24, valve 45 remains blocked and valve 55 conducts and since its resistance is very low relatively to resistor 57 the chute tip is substantially at earth potential and the dark bean remains undeflected. The Provisional Specification describes a simplified system in which the photo-cell is connected in series with a resistance across the high voltage supply to the deflector plates the tip of the chute being connected to the photo-cell side of this. resistance. In a further embodiment the photocell varies the bias of a triodo connected across the supply to the deflector plates in series with a resistance. This bias variation makes the triode resistance high to low relative to the fixed resistance and varies the potential of the chute tip connected to the junction of the triode and the fixed resistance. A reference is also made to a system in which a Wheatstone bridge compares the output of the photo-cell with that of a cell " looking at " a standard bean, the output of the bridge varying the bias.

IPC: F04B13/02
Filed: 1953-07-20
Abstract: 747,571. Mixing fluids in flow in proportionate quantities. UNILEVER N.V. July 15, 1954 [July 20, 1953], No. 20026/53. Class 86. [Also in Group XXVIII] A proportioning pump having a plurality of cylinders capable of delivering at least two liquids in any desired proportion without throwing the pump substantially out of balance has a casing 1 in which a crank shaft 2 is mounted and driven by a shaft 7. The casing has three guides 10 for crossheads 11 each of which is connected to the crankshaft by a connecting rod 12. Bolted to casing 1 is a cylinder block 17 having three main cylinders 18 of equal bore, each being provided with a piston 20 bolted to a piston rod 22 extending from the respective crosshead 11 and each having a poppet type inlet valve 23 and outlet valve 24 normally forced against their seats by compression springs, not shown. The cylinder head of one of the main cylinders 18 has an aperture 32 in which a secondary cylinder 33 is mounted, in alignment with the main cylinder. Cylinder 33 has a piston 34 coupled in tandem with piston 20 by a rod 35 and is provided with spring-loaded inlet and outlet valves 41, 42. In operation, the liquid in the larger proportion is delivered by the cylinders 18 and the other liquid by cylinder 33. By variation of the bore of the latter, any desired proportion of the liquid can be obtained, the balance of the pump being unaffected since the total output supplied by cylinder 33 and the associated cylinder 18 is always equal to the output supplied by each of the other cylinders 18. For accurate adjustment of the output of cylinder 33 and to take into account variations of the volumetric weight of the liquids its pump chamber 37 is provided with a trimming device 48 comprising a guide 49 screwed into an aperture 50 in that chamber, a free piston 51 being movable in the guide between the aperture and an adjustable stop 52 at its outer end. The piston 51 is forced towards the aperture by a spring 54 whose strength is such that the piston is moved against stop 52 before the pressure built up in chamber 37 is sufficient to open valve 42, the amount of liquid delivered from cylinder 33 being consequently reduced by the volume displaced by the piston 51. In a modification, the secondary cylinder is placed in parallel with a main cylinder on a common crank, the diameters of the two cylinders being chosen to give a total output equal to that of each of the other main cylinders.

Filed: 1955-07-13
Abstract: 816,503. Lathe-details. MASCHINENFABRIK HEID A.G. July 13, 1955 [July 21, 1954; Nov. 16, 1954; Feb. 18, 1955], No. 20281/55. Class 83 (3). A lathe comprises a headstock carrying a single horizontal work-spindle 7, Fig. 4, ard a bed 1 provided with front and rear longitudinal slideways along which a saddle having an upper guide-surface (represented by XX) is longitudinally movable parallel to the work-spindle axis, with said upper guide surface moving in a plane, the spindle being adjustable parallel to itself between two positions 7, 7<SP>1</SP>, relative to the bed, in the second 71 of which the axis of the spindle is positioned both further above said plane and also further rearwards of the front slideway of the bed than it is in the first position. The headstock proper may be rotatable in a cylindrical bore in a housing, and the workspindle arranged eccentric to the bore to give an arcuate adjustment as above, or the headstock may be pivoted to give the adjustment. In an alternative arrangement, Fig. 2, the headstock 10 with its spindle 7 is adjusted along a wedgepiece 13 by a screw-and-nut gear 63, 61. The tool-holder is moved to a higher position 3<SP>1</SP> to correspond with the work-spindle in the raised position 7<SP>1</SP>. In a further arrangement, Fig. 9, the saddle guideways 46 are arranged at different levels so that the saddle slopes downwardly towards the rear of the lathe. The headstock is adjustable horizontally on transverse guides 52, the relative effect being to move the work-spindle 51 rearwardly and upwardly as regards the upper guide-surface 49 of the saddle. The effect of all the arrangements is to increase the effective " swing " of the lathe.

Title: Improvements in alternating current signal receivers
IPC: H04Q1/453
Filed: 1931-07-15
Abstract: 381,960. Exchange systems. RYALL, L. E., 159, Westmead Road, Sutton, Surrey. July 15, 1931, Nos. 20321/31 and 2049/32. [Class 40 (iv).] An electrical signalling system in which the transmission of signals occurs on cessation of current flow comprises receiving equipment which operates differently according to whether the current is stopped suddenly or gradually. The invention may be used to discriminate between speech currents and voice-frequency signals in telephone systems since speech currents do not cease abruptly, and the receiving equipment may be adjusted to repeat a train of voice-frequency impulses or to remain operated during the receipt of such a train. In the first arrangement, Fig. 1, signals from line 1, 2 are applied to the grid of valve 5 normally biased by battery 6 to pass sufficient anode current to hold relay 7 operated. Amplified signals are rectified at 13 and the voltage applied across a condenser 14 to increase the negative bias of the valve, but the presence of the signal current maintains sufficient anode current to hold relay 7. The condenser is shunted by relatively high and low resistances 15, 16 respectively. If signal current ceases abruptly, relay 7 relapses to close a local signal circuit 8 and to open the low resistance shunt 16, and condenser 14 slowly discharges over 15 after which 7 pulls up again. If signal current ceases gradually, 14 has time to discharge over low resistance 16 before its cessation and the receiver is unaffected. The apparatus may be made responsive to a particular frequency by providing a tuned circuit 11, 12, and if more than one frequency is used, the input transformer may have a corresponding number of secondary windings each associated with a tuned receiver, or the frequencies may be passed to their respective receivers by filter circuits. In the modification, Fig. 3, signals are amplified by valve 25 so that valve 31 runs into grid current and increases the negative potential on condenser 34 which is shunted by high and low resistances 35, 36 as before. Operation on sudden and gradual cessation of signal current is similar to that of the first arrangement. The first Provisional Specification describes one arrangement somewhat similar to Fig. 1 above but independent of the nature of the cessation of signal current, and a further arrangement similar to Fig. 3 in which the receiving relay on relapse closes a local circuit over a second winding in opposition to its normal control. winding. Neither of these arrangements has the low resistance discharge circuit controlled by contacts of the relay.
