Title: Rotary compressor plants
IPC: F04D27/02
Filed: 1955-06-22
Abstract: 771,638. Axial-flow and centrifugal compressors. SULZER FRERES SOC. ANON. June 22, 1955 [July 5, 1954], No. 18101/55. Class 110 (1). A plant for supplying air to metallurgical furnaces comprises a compressor having at least two stages and driven at constant speed, and a single-stage recuperator turbine having adjustable blading, to which air is supplied from an intermediate point of the compressor. Air is supplied to a metallurgical furnace 1 by a compressor comprising axial-flow low-pressure stages' 7 and one or more centrifugal high-pressure stages 8. The compressor is driven through step-up gearing (not shown) by a synchronous electric motor 3 and also through a coupling 4 (which may comprise disengageable gearing) by a single-stage turbine 5. The turbine 5 is driven by air extracted from the compressor upstream of an intercooler 11. Regulation of the pressure and quantity of air delivered to the furnace 1 is effected by varying the quantity of air diverted through the turbine 5, by means of adjustable guide vanes 14. The turbine 5 exhausts either to atmosphere, as shown, or into the suction pipe of the compressor. The high-pressure stage of the compressor may be of the axial-flow type.

Title: Method for removal of heavy objectionable material from cereal, legumes and other food products
IPC: B02B1/02
Filed: 1946-06-17
Abstract: 646,639. Pneumatic separating. SUTTON, STEELE & STEELE, Inc. June 17, 1946, No. 18113. [Class 117] Heavy particles of a mass of intermixed divided materials of different specific gravities are separated from light particles, for example, in the removal of heavy objectional material from cereals, legumes and other food products by continuously feeding the mass as from a shoot 18. on to a longitudinally inclined trough-shaped pervious deck 2, agitating and stratifying the material by simultaneously rapidly reciprocating the deck longitudinally and forcing air upwardly through the deck. The upper strata 2<SP>1</SP> of light material is permitted to move down the deck in response to the force of gravity but is positively obstructed as by an adjustable wall 8 until a bed of predetermined thickness of the light material is established on that area of the deck between the point of material feed 18 and the lower end of the deck. The inclination of the deck, the speed of reciprocation thereof and the amount of air forced upwardly through the deck are such that the heavy underlying strata composed of heavy particles will not move up the deck until they are forced into close relationship with one another and into frictional engagement with the deck by the force and weight exerted upon them by the bed 21 of lighter particles. The width of the stream of heavy particles is progressively narrowed, as by converging walls 4, as the heavy particles move up the deck and are discharged from the upper end of the deck through a passage 9. The apparatus described for carrying out the process is the same as that described in Specification 646,698. Specification 207,094, [Class 117], also is referred to.
Patent GB-292562-A (GB)
Title: Improvements in and relating to sewing machine bobbin winders
IPC: D05B59/00
Filed: 1928-06-22
Abstract: 292,562. British Thomson-Houston Co., Ltd., (Assignees of Stephenson, H. M.). June 22, 1927, [Convention date]. Spool, bobbin, and the like, winding. - A spool-winding means is in driving association with the stitchforming mechanism which is automatically disconnected from the driving means when a spool is inserted for winding, and reconnected when the full spool is removed. An electromotor 24, Fig. 2, drives a shaft 25 to rotate the shaft 26 of the spool winding means through gears 28, 27. A gear 30 on a collar 26<a> on the shaft 26 actuates the needle bar and take-up through gears 23, 21, and a vertical shaft 17 geared to the shaft 16. The gear 23 rotates a horizontal shaft 22 carrying the looper and the lower end of the shaft 17 rotates an eccentric 19 for operating the feed-bar. The spool-winding shatt rotates continuously when the motor is running and normally drives the stitch-forming mechanism by a pin 31 engaging a recess 29<a> in the collar. When a spool 36 is placed on the reduced end 35 of the shaft 26 for winding, a follower 43 is moved aside and the spool is pressed down until retained by a finger 47 on the follower. This operation causes the spool to press down a collar 33 and depress the collar 26<a> against a spring 32 through the rod 39 and flanges 42, 29, disengaging the pin 31 and slot 29<a>. The stitchforming devices are thus put out of driving connection with the shaft 26 and the spool is rotated by a pin 37 engaging a slot 36<a>. When the spool is full, the follower 43 rocks on its pivot 44 against the spring 45 and frees the finger 47. The spool is then thrust upwards by the collar 33, rod 39, and springs 33, 41 till the pin 37 and slot 36a are disconnected, when the shaft 26 ceases to rotate the spool. The spool is stopped in the position by a second finger 48, Fig. 6. The rod 39 does not rise fully to recouple the pin 31 and slot 29<a> till the spool is removed. Fig. 11 shows a modification wherein a finger 58 on the follower engages the collar 50 instead of the spool 36 and the follower 54 itself performs the function of the finger 48 by engaging the lower flange of the spool when it is full and the collar has been released by the finger 58. Specification 291,797 is referred to.

Title: Improvements in machines for grading eggs or like objects by weight
IPC: B07C5/26
Filed: 1933-06-26
Abstract: 421,607. Grading eggs &c. by weighing. WHITMORE, F. L., Newland, Burkitt Road, Woodbridge, Suffolk. June 26, 1933, No. 18161. [Class 143] Relates to an egg &c. grading or sorting machine wherein the grading is effected by the tilting of a counterpoised beam along which a poise weight is moved from one position to another whilst the beam is prevented from tilting, and consists in providing the beam with positioning notches or the equivalent so that the poise weight can slide into the notches and be located in these positions free of the poise-moving member. As shown in Fig. 2, a number of scale beams 7 (one only shown) are carried upon a constantly rotating spider 5 and each beam carries a sliding poise weight 10 adapted to be moved to positioning-notches along the beam by means of stationary cams 12. When stationed at a notch the poise is free of the cams. The eggs may be fed automatically to the scale pans 25 by means of one or more feeding devices each comprising two vertically-moving stops actuated by projections on a stationary cam strip 21 as the beams arrive at the feeding points. A further stationary cam 15 engages a depending arm 14 on the beam and prevents tilting or jolting when receiving the egg. When the first grading position is reached the cam 15 liberates the arm 14 and if the egg is sufficiently heavy permits the beam to tilt, and the egg to roll out into its grading receptacle. Lighter eggs are carried forward and, at each stage the poise weight 10 is moved one step towards the beam fulcrum and the eggs are similarly tipped according to their weight into successive grading receptacles. Eggs below a predetermined weight are carried forward and tipped into a " smalls " receptacle by means of a further stationary cam acting on the arm 14. A stationary cam 13 restores the poise weights to their initial positions. At each grading point a counter actuated by the arm 14 when in its tilted position, registers the number of eggs graded.

Title: Improvements in or relating to synchronized clock systems and secondary clocks therefor
IPC: G04C13/03
Filed: 1930-06-13
Abstract: 352,207. Electric clocks. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(International Time Recording Co. of New York; Endicott, New York, U.S.A.) June 13, 1930, No. 18171. [Class 139.] Synchronizing.-A synchronized clock system, in which the master clock sends normal (timetransmitting) and faster than normal (stepping-up) impulses to the secondaries, also has means in the master for reversing the direction of flow of successive impulses to the secondaries, means at each secondary for actuating the hands unidirectionally, irrespective of the direction of current flow, and means controlled by the position of the secondary hands for determining whether the secondary shall receive faster impulses or no normal impulses until the synchronizing moment. At the master clock contacts 14, 16 are closed once an hour, contacts 17, 17<1> are closed each once in two minutes alternating with one another, and contacts 19, 19<1> are closed by the escapement 11. Contacts 14 close for the synchronizing period, just after the 44th minute to nearly the 60th minute, contacts 16 close from just after the 59th minute to 59¢ minutes. When contacts 17 close, a circuit +ve, 32, 33, 34, 17. 35, 36, 37, 31, -ve energizes relay 36. This raises armature 38 and current flows to advance the secondary hands over circuit +ve, 30, 38, A, 39, 25, 24 (or 38, 40, B, 41, 26, 24) 21, ground C, 38<1>, and -ve. At the next minute 17<1> close instead of 17 and reverse the current through the secondaries as follows. When 17<1> close, 38 remains lowered and a circuit +ve, 32, 33, 17<1>, 351, 361, 37, -ve energizes relay 36<1> to raise armature 38<1> so that the current for the secondaries is over circuit +ve, 30, 38<1>, C, 21, 24, 25, 39, A, 38, (or 24, 26, 41, B, 40, 38), 31, -ve. At each secondary clock the reversals of current are used by a double coil 21 to drive a shaft 22 and minute shaft 20 unidirectionally. An S-shaped armature is normally polarized by a permanent magnet and the alternate polarization imposed by the coils 21 swings this armature 90‹ each time, always in the same direction. A synchronizing cam 23 on the minute shaft of each secondary clock coacts with blade 24 so that when the secondary minute hand is at the 59th minute, blade 24 falls off point 27, opening 24, 25 and closing 24, 26. At 29 minutes after the hour, the rise 28 recloses contacts 24, 25. When synchronizing starts at the 44th minute contacts 14 close and coil 44 is energized to raise armature 40 so that line B is opened. If a clock is fast, when it shows 59 minutes contacts 24, 25 are opened and no more impulses reach its magnet 21. Just after the 59th minute of the master, contacts 16 close and contacts 19. 19<1> rapidly energize the slow secondaries over line A until they are stepped-up to show the 59th minute. At 59¢ minutes contacts 16 open and just before the 60th minute contacts 14 open, so that armature 40 recloses line B and all the secondaries restart on time.

[Class 59] Household refuse &c. is subjected to a turning over, mixing and grinding action in a, rotating or oscillating container simultaneously with screening or sifting. As shown. refuse is fed through a shoot 42 to a rotary container 10 provided with an internal stepped screen 22. The drum is mounted on rollers 11 and is divided by a screen 16 into chambers 12, 14. The peripheral screen 22 in the chamber 14 has the radial portions fitted with extensible partitions 24 which are adjustable radially to control the output from the mill. An internal cone or triangular member 26 with vanes 28 is provided in the chamber to deflect the material &c. onto a screen 36 the outside of the screen being protected by a fixed semicircular guard-plate 48 which prevents screened material from passing back to the chamber 14 through screen 36. A vane 46 rotates around a screen 38 and a vane 50 discharges the sifted material. In modifications, conical partition screens may separate the compartments and the screened material may be discharged directly from each compartment. The screens 22 may be cleaned by a pricker device which operates by gravity or by cam action to pierce the holes in the screen at each revolution. The material discharged from the drum may pass down a shoot to be sterilized by heat, gases or ultra-violet rays, and then sifted into grades, the rejected material passing over a conveyer belt where tins &c. are removed magnetically. The drum may be inclined and may be pivoted for discharge by tilting. The ends of the drum may be movable to vary the discharge opening. In a mill comprising several chambers, the chambers may be driven at different speeds.
