Title: Improvements in the manufacture of wheaten flour
IPC: A21D2/02
Filed: 1940-04-24
Abstract: 540,687. Bleaching and conditioning flour. LORING. F. H. April 24, 1940, No. 7352. [Class 58] [Also in Groups XI and XXX] For bleaching and conditioning wheaten flour, ammonium chloride or other halogen compound is exposed to an electric arc in, the presence of air, and the resulting gases are passed into the flour whilst in a state of agitation. As-shown, the halogen compound is fed to two arc chambers 1 from two adjacent hoppers 11 by worms 8 driven alternately by the engagement of a driven friction-wheel 13 upon a swinging arm 14 with friction-wheels 10 upon the worm shafts. The compound passes forward into an arc-surrounding fitting 6 within each chamber 1 into which air is pumped through a passage 3. The air passes up through the fitting and the gases resulting from the exposure of the air and compound to the arc leave the chamber by a passage 4 leading to the flour container. Each electrode 2 is reciprocated in step with the piston of the air pump, the up-and-down motion of. the piston-rod operating a walking beam which actuates the electrodes and, at the same. time, through a spring-fitted link 17, effects the swinging of the wheel 13. A freely running toothed wheel 12 prevents arching of the compound within the hopper and clogging of the worm; or this clogging may be prevented by a cleaning brush or travelling scraper lightly traversing the worm. The worm housing may be water-cooled and may be made in two halves. Specification 196,697, [Class 58], is referred to.

Title: Apparatus responsive to preselected changes in the magnitudes of physical variables
IPC: G01L13/02
Filed: 1950-03-23
Abstract: 668,006. Gauging departure from standard form; gauging-apparatus positively controlling sorting operations. SANDVIKENS JERNVERKS AKTIEBOLAG. March 23, 1950 [March 28, 1949], No. 7364/50. Class 106 (ii). [Also in Group XXIX] A gauging apparatus connected to a source 6 of compressed air or other pressure medium has a resiliently-mounted member 19 movable in accordance with the dimension being gauged but whose movement is suddenly amplified by an adjacent magnet 20 whenever its distance from the magnet is sufficiently reduced, thus causing the member 19 to close a jet 22 controlling a piston or the like which may then reject the item being gauged as having dimensions not conforming to those permissible. As shown, any axial movement of a feeler member 11 from its position of symmetry causes a pressure difference to be set up in a pair of bellows 14 and 15 whose movable extremities are connected together by a frame 16. The resulting movement of the bellows, and hence the frame 16, are imparted to the members 19 through spring blades 17 mounted on a main frame 18. The members 19 are connected to or comprise a magnetic material. The source 6 of compressed air is also connected through chambers 25 and pipes 24 to orifices 22 extending through magnets 20, one magnet being spaced from each of the members 19. The magnets 20 may be of the permanent or the solenoid type. When the movement of a member 19 is such that it is suddenly attracted to its magnet 20, to close the orifice therethrough, there is a sudden rise of air pressure in the associated chamber 25 which may be used to actuate, through a pipe 28, a piston or other member as described above. With the arrangement shown, one of the two chambers 25 can be used to displace oversized items in one direction and the other, chamber can be used to displace undersized items in another direction. According to a modification, a single member 19 is disposed between the poles of a single magnet.

Title: Improvements in or relating to fluid flow meters
IPC: G01F1/37
Filed: 1927-03-17
Abstract: 286,469. Sandison, A. G. S., and Electrofio Meters Co., Ltd. March 17, 1927. Liquid-level pressure gauges.-In a fluid flow meter the measuring circuit is controlled by the differential pressure across an orifice 2 and automatic means is provided, controlled by, and to correct for pressure, temperature, or density variations by adjusting the voltage tapping on a transformer in the measuring circuit. Fig. 3 shows a differential manometer 5 varying a resistance 1 in circuit with indicating, recording or indicating instruments having a current winding 7. Correction is applied by movement of one or more contact brushes 15 over tappings 12 on the transformer 10 to vary the voltage applied to either the control winding 8 or to the circuit including the resistance 1 and the current winding 7. The contacts and brushes are preferably so arranged that no brush 15 touches two contacts 12 at once and the resistance 16 between a pair of brushes is sufficient to limit the current when two contacts are engaged. In a modification one set of brushes and contacts is arranged in the primary and another set in the secondary of an auto-transformer in the circuit including resistance 1 and the current winding 7. Fig. 5 shows a construction in which correction is made for one variable by means of a Bourdon tube 43 arranged to rotate an arm 38 carrying brushes 15 attached to flexible strips 35 moving over the tapping contacts 12 of the transformer 10. A pointer 48 is carried by the arm 38 to indicate temperature or pressure, in the former case the inlet 47 is connected to a bulb containing an expansible medium subjected to the temperature to be corrected for.

Filed: 1968-02-16
Abstract: 1,205,895. Ventilating livestock houses. W. POTTER & SONS (POULTRY) Ltd. 16 Feb., 1968, No. 7658/68. Heading F4V. [Also in Division G3] A room is ventilated through a plurality of ducts in which the flow of air through each duct is controlled by a motor-driven regulator positioned within the duct and under the control of a function of temperature and/or humidity of the air in that part of the room affected by the flow of air through that duct. As described, flow of air through each of a number of ducts in the roof, walls and/or floor of a two-story livestock house is separately controlled by a fan or vane responsive to the temperature and/ or humidity of the air in a part of the house, e.g. a passage, affected by the flow of air through the duct. In Fig. 3, a bridge circuit 34, including a capacity responsive to the humidity, produces a voltage which is modified in dependence on temperature by a temperature variable resistor 41 and combined with the voltage from a potentiometer 36 which determines the desired condition of the air. Any change in the resultant voltage is applied through a transistor amplifier 39 to a S.C.R. 42 shunting the output of a rectifier 45 to vary the energization of a winding 24 of a capacitor-start induction fan motor. The speed of the fan is thus varied to correct the air condition. In a modification, flow of air through the duct is controlled by a vane adjusted by an induction motor operated in the appropriate direction by one or other of two circuits of the type circuits of the type described above.

Title: Improvements in processes of and devices for electrically exploring the ground by means of alternating currents of very low frequency
IPC: G01V3/06
Filed: 1929-03-11
Abstract: 308,256. Ambronn, R. March 20, 1928, [Convention date]. Prospecting for minerals. - For electrically exploring the ground, alternating currents of very low frequency, preferably between 0.3 and 10 periods per second, are sent into the ground and their effects are observed bv means of a measuring - instrument tuned to the same frequency. The low-frequency alternating current may be produced by the means shown in Fig. 1, in which an annular resistance W is supplied at diametrically opposite points a with continuous current from a source E and is wiped by rotating insulated brushes b connected to slip-rings. Alternatively the low-frequency alternating current may be generated by a slowly rotating dynamo, a thermo-ionic generator, or a mechanical commutator. At the point to be explored, probes S1, S2, Fig. 4, are connected through a variable resistance Ws and the primary winding of a transformer Tr, to the secondary winding of which is connected, through an amplifier V, a galvanometer G tuned to the frequency of the current supplied to the ground. The transformer Tr may be omitted or may be replaced by a choking-coil, across the ends of which the amplifier V is connected through condensers. By changing the positions of the probes S1, S2 until no alternating current passes between them, the equipotential lines may be plotted. By setting the probes at right-angles to these lines, the difference of potential and the resistance of the ground between them may be determined. The difference of potential between the probes may be compared to that of the main current or a branch thereof. Such an arrangement is shown in Fig. 6, in which one winding P of a transformer Tr is connected across a variable resistance Wh traversed by the lowfrequency alternating current supplied to the earth at points F1, F2 by the generator E. A second winding S of the transformer Tr is connected to the probes S1, S2, the galvanometer G being connected through the amplifier V to a third winding Z. In a modification. Fig. 7, the compensating tension is tapped from a resistance Vk across the secondary winding of a transformer Tr1, the pirimary winding of which is in series with the generator E. The primary winding of a second transformer Tr2 is connected between the probes S1, S2. Complete compensation is ascertained by means of a telephone Tel by superimposing an audio-frequency current by means of a device Ueb. Other arrangements. are shown in Figs. 8 and 9.
