Title: Improvements relating to conveyors
IPC: B07B1/10
Filed: 1933-12-04
Abstract: 426,890. Endless - belt conveyers. ALLEN, W. H., 142, Salisbury Road, Moseley, Birmingham. Dec. 4, 1933, No. 33975. [Class 78 (i)] A flexible steel or other conveyer belt 1, Fig. 3, has a plain central portion 2 on which the material is carried and perforated side portions 3, 3 through which it is discharged to a series of hoppers 4. Material is deflected from the part 2 to the sides by fixed ploughs 5, any material that does not fall through the perforations being returned to the part 2 by fixed ploughs 6 and carried on to the next hopper. Each plough is movable vertically and is pressed lightly into engagement with the belt by springs 12, Fig. 2. Any set of ploughs can be raised from the belt to be put out of action by a lever 13. A fixed wiper 7 carried by the hopper 4 bears against the under surface of the belt and prevents material being carried from a filled hopper on to the belt supporting rollers, &c. Material remaining on the belt at the end of the run is transferred by a plough and shoot to the central part of the lower run and taken back to the feeding point where it is discharged. This transfer from the upper to the lower run may take place at any point in the upper run. The belt 1 may be replaced by three parallel belts spaced apart and the discharge may take place through the gaps between them. In another modification the belt has a plain carrying portion at one side and a perforated delivery portion at the other. In a further modification adapted for the selective distribution of a plurality of parallel streams of material, the belt comprises a central perforated portion and side plain portions, and the ploughs are movable so that either of the streams may be deflected first on to the perforated portion adjacent any hopper and re-deflected on to the plain portion. In all constructions rotary or otherwise movable brushes may be provided above or below the perforations to assist the passage of the material through them. The belt may be replaced by a conveyer of the slat or tray type. Specification 427,159 is referred to.

Abstract: 426,928. Rotary engines and pumps. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT.-GES., Friedrichshafen-on-Bodensee, and THUNGEN, H. F. VON, 6, Schloss-Strasse, Friedrichshafen-on-Bodensee, Germany. Nov. 26, 1934, No. 33997. [Class 110 (ii)] A rotary engine or pump with an inclineddisc piston 8 coupled to a rotary inner casing 2 and having a number of partition plates 19 passing through slots in the disc to form with the inner casing several working spaces has the contact surfaces of the inner rotary casing and the outer fixed casing, where they are exposed to the pressure of the fluid in the inlet and outlet passages 13, 13<1>, 14, 14<1>, so constructed that the pressures are centrally and oppositely directed. Jamming due to tilting couples is thus avoided. As shown, the rotary inner casing 2 has a spherical exterior, but a conical form adjacent the ports 13, 13<1>, 14, 141 could be used. The interior faces of the rotary casing are grooved out to permit the rocking movement of the partition plates 19. The capacity can be varied by a screw-block 11 which alters the inclination of the disc piston 8.

Title: A machine for cutting out cloth or the like
IPC: B26F1/04
Filed: 1959-10-08
Abstract: 859,526. Selective punching machines. REICHERT, K., [trading as KRAUSS & REICHERT]. Oct. 8, 1959 [Oct. 16, 1958], No. 34117/59. Class 31 (2). A machine for cutting out blanks 20, Fig. 9, from cloth or the like 69 to be made into garments comprises punches for punching overlapping holes 21 in the cloth, the punches being operated automatically in accordance with a pattern fed through the machine. The punches a, b, c, d and e, Fig. 10, are disposed in overlapping relationship in the transverse direction Q in rows A to D, each punch overlapping a neighbouring punch by an amount m. The cloth 69, Fig. 3, is fed stepwise through the machine and is punched by means of spring - influenced punches 87 carried by an assembly which is reciprocated vertically by means of an eccentric 98 co-operating with a cross beam 81 provided with projections 95, 96. The punches are actuated through the intermediary of pivotally-mounted spring - influenced interposers 92 which are connected by rods 97 to electromagnets 66. Each feed step of the cloth corresponds with the space x, Fig. 10, between punch centres. The cloth is held during the punching operation by a spring- influenced clamp 85. A pattern 34, Fig. 6, having graphite or similar markings thereon is fed stepwise in synchronism with the feed of the cloth 69 and is sensed by spring- urged detecting elements carried by an assembly which is reciprocated vertically by means of an eccentric 53 co-operating with a thrust block 54. The detecting elements each comprise a finger 61 slidably mounted within, and insulated from, a sleeve 57. The sleeve and finger are both formed of electrically conducting material and are connected by leads 64 to an amplifier 65 having leads 79 to an electromagnet 66 in the punching assembly. In operation, when detecting elements contact graphite markings, the corresponding electromagnets 66 are energized to swing the corresponding interposers 92 into operative position to cause the corresponding punches to be actuated to punch the cloth. The pattern may be in the form of a punched card instead of having graphite markings. Alternatively, photo-electric detecting devices, or electromagnetic detectors responding to magnetic ink markings, may be used.

Abstract: 942,244. Return-tube steam boilers. M. C. K. DE PORAY. Sept. 7, 1962 [Sept. 15, 1961], No. 34418/62. Heading F4A. In a return tube boiler a vertical partition 15 secured to the lower part of the shell 1 and extending between the tube plates 8a, 10a divides the water space into zones A and B respectively containing an eccentrically mounted fire tube 3 and a laterally positioned nest of smoke tubes 9. To promote water circulation in the zone A, the fire tube near its outlet end has a portion 5 of reduced diameter which is lined with heat insulating refractory material to prevent evaporation of water which can then circulate as shown by the arrows f1 . . . f5. Feed water enters the lower portion of the zone B through a pipe 16, is heated by the lower tubes 9b and evaporated by the upper tubes 9a. To promote circulation around the upper tubes an arcuate baffle 13 forming with the adjacent shell surface a downcomer space is provided, a deflector plate 14 diverting the descending stream into the tube bank, as shown by the arrow c. The smoke tubes are provided with gas accelerating cores 17 and soot-blowing steam or air nozzles 18.

Title: Gyroscope control
IPC: G01C19/44
Filed: 1969-07-10
Abstract: 1278794 Photo-electric control of gyroscopes SPERRY SUN WELL SURVEYING CO 10 July 1969 [10 July 1968] 34828/69 Headings G1A and G1C A gyroscope with only two degrees of freedom, for use in borehole surveying instruments, uses photo-electric control means to maintain the inner gimbal at right angles to the plane of the outer gimbal. The inner gimbal 20 carrying the rotor 24 also carries a bent arm member 56, having a portion 64 interposed between a lamp 60 and a pair of photo-cells or photo-resistors 66, mounted on the outer gimbals 12. When the instrument tilts from the vertical, the inner gimbal tends to move away from a position 90 degrees to the outer gimbal, causing the arm 56 to move and cause unequal illumination of the photo-cells. Depending on the direction of tilt, one of the cells produces an output which is amplified to actuate a relay causing the motor 46 to start rotating shaft 44 in a particular direction. This rotation is transmitted to brush holder 34, causing frictional force on slip rings 28 by brushes 38 and a torque on shaft 16. This causes precession of outer gimbal 12 and, as a result of this, precession of inner gimbal 20 until it retains its 90 degree relationship with outer gimbal 12. The slip rings 28, brushes 38, a second set of brushes 41 and rings 42, and conductors 52, represent the power supply means for the instrument and the means to conduct control signals from the photocells to the control circuit 54.

Title: Improvements in and relating to gas-blast electric circuit breakers
Inventor: MORETON PERCY
IPC: H01H33/32
Filed: 1954-12-03
Abstract: 818,521. Gas-blast switches. ENGLISH ELECTRIC CO. Ltd. Dec. 2, 1955 (Dec. 3, 1954], No. 35070/54. Class 38 (5). A gas-blast switch 3 has means to maintain the blast valve 6 open once it has opened during an opening operation, the means becoming inoperative only when an isolating contact element of the switch has completed at least a major part of its movement to an open position. When the switch is to be opened, the coil 10a of a pilot valve 10 is energized moving the valve to the left and admitting air under pressure to a valve 9a. This causes valves 9a and 9b to move down to open valve 9b and admit pressure to the left-hand side of a piston 8a. The piston 8a moves a two-way valve 8 to the right to cut off the air supply to the space below a piston 6a and to exhaust this space to the atmosphere. The pressure in the chamber la moves the piston 6a down to open the blast-valve 6. Pressure air entering the column 1 can now act through a non-return valve 12, a cut-off valve 14, a pipe 11 and a non-return valve 13 on the valve 9a to maintain the valves 9a, 9b in their lower position, so maintaining the valve 6 open until an isolating contact arm 15 has been moved sufficiently to close the cut-off valve 14. At this instant the coil 10a would normally be de-energized e.g. by the opening of auxiliary contacts associated with the arm 15. In a multiphase arrangement the pipes between the valves 12, 14 associated with the respective phases may be interconnected by a pipe 16 to ensure that the switch of one phase cannot remain closed while the others open. In Fig. 2 (not shown), the pipe 11 may be connected so that the maintaining pressure acts directly on to the piston 8a. In a further arrangement similar to that of Fig. 1, the maintaining pressure is derived from the pipe between the valve 9b and cylinder 8b, Fig. 3 (not shown). The isolating contact may be an arm 15 as shown, but it could be one of the main interrupting contacts which, by continued movement, establishes an isolating gap.
