Title: Apparatus for plucking the feathers from birds
IPC: A22C21/02
Filed: 1927-07-13
Abstract: 303,913. Sieff, S. H. July 13, 1927. Poultry, dressing.- Apparatus for plucking the feathers from birds comprises means for gripping and extracting the feathers and means for supporting the flesh in proximity to the stems of the feathers being extracted so as to resist the pull and prevent laceration of the flesh. The portable apparatus shown comprises a fork-like frame 1 carrying a drum 4 driven through toothed gearing by a motor-driven flexible cable 5. Partly projecting through the frame is a rubber covered roller 18 driven by friction rollers on a transverse shaft driven by the gearing, which roller makes contact with the bird's skin and keeps it taut. The frame carries a plate with fingers 20, 21, alternate fingers having flat parts 22, to arrange the feathers in single file and support the flesh to withstand the pull. The gripping and extracting means comprise pairs of radial grooved jaws mounted in line on the drum 4. The jaws 23, 24, Figs. 8 and 9, are secured to carrier bars 25, 26 connected to blocks 27, 28 guided in transverse slots in a spider 30 within the drum 4. Auxiliary blocks 35 are arranged in guides and springs 36 are arranged between them and the blocks 27. The ends of the bars 25, 26 and blocks 35, 28 engage fixed concentric face arms 31, 33 respectively arranged on either side of the drum which positively open and close the jaws. The springs 36 allow the jaws to open when a bunch of feathers is gripped. The plucking operation may be effected within the vicinity of a cowl under suction and the feathers passed down a chute. In a stationary form of the apparatus, the drum is driven directly and is mounted in a frame within the front end of a cowl-shaped casing with the fingers projecting vertically at the open front towards a supplementary finger plate which keeps the bird from entering the casing. The lower part of the casing may communicate with a suction chute to remove feathers.

Title: Improvements in and relating to electric valve converting systems
IPC: H02M7/15
Filed: 1950-07-26
Abstract: 672,515. Rectifying ; automatic current control systems. BRITISH THOMSONHOUSTON CO., Ltd. July 26, 1950 [Aug. 4, 1949], No. 18681/50. Classes 38 (ii) and 38 (iv). In a converting system electric discharge type converters, which as shown may be ignitrons 15, 16 used as rectifiers, are supplied from phase-displaced windings of transformer 4 divided into groups such as 8, 10, 12 and 9, 11, 13, the division of load between the groups being controlled by variation of phase of the peaky control voltages supplied to the converters, using saturable reactors controlled by current varying with the difference in the currents carried by two of the groups. In this way current unbalance due to harmonics generated in the five-legged core of transformer 4 is removed. The differential current is obtained from across a resistance 41 connected across the differentially connected secondaries 39, 40 of current transformers energized in response to the currents passing through windings 11, 8 of different groups of main transformer windings and passes through windings 50 of unsymmetrically saturable reactors 49. These reactors are so arranged in pulsing circuits 21-23 which produce firing peaks for the ignitors by discharging condensers 29 through self-saturating inductors 30, that their saturation by the differential current produces second harmonics at their terminals and advances the firing peaks in one group of ignitor and retards it in another to equalize the load between the groups. In a modification the place of the differential circuit including resistance 41 is taken by two windings on each saturable reactor 49 which respectively carry the total load current of each group of transformer windings in such directions that they produce opposing magnetic fields, Fig. 2 (not shown). Specification 292,110, [Class 38 (ii)], is referred to.

Filed: 1963-05-14
Abstract: 1,048,692. Lathes. M. TSUDA. May 14, 1963 [Aug. 22, 1962], No. 18987/63. Heading B3T. In a ram type turret lathe (Figures not shown) an indexable turret head 11 carrying a plurality of cutting tools is mounted on a ram 10 carried on a saddle 9. The turret effects feeding and return movements which may be actuated manually or automatically. Manual operation is effected by a star handle 6 on a shaft 7 which engages through a pinion 12 a rack 13 on the underside of the ram 10. Clutch members 16- 20 normally disengaged during manual operation is engaged for automatic power feed, the engagement of the clutch members. 16-20 energizing the main spindle motor of the lathe. The automatic operation of the lathe comprises a control mechanism which provides rapid traverse of the turret up to the normal feed position and includes a shaft 7 connected to a magnetic clutch 29 which operates a reversible electric motor 35. To effect normal feed of the turret a control lever operated by a solenoid 41, actuates the clutch assembly 16-20 and a manually operable stop lever 44 maintains the control lever 36 in its operative position. The turret assembly 11 is indexed by bevel gears within the turret which are connected by a transmission rod 56 of a collar 47 carrying six adjustable stop-screws 48a-48f. A gear 49 on the collar 47 engages with a gear 57 mounted on a hexagonal positioning cylinder 58 indexable with the turret and which has dogs 63a to 63f. A microswitch 64 co-operates individually with the respective dogs 63 which determines the turret traverse in a predetermined sequence. A star wheel 66 at one end of the positioning cylinder has six radial projections which cooperate sequentially with another microswitch 73. In operation, the machine spindle motor is started which transmits a drive to the shaft 22. Another switch is operated to start motor 35 and engage clutch 29 which effects rapid forward traverse of the turret to the workpiece and which is stopped by dog 63a actuating switch 64. Solenoid 41 is then energized which operates the feed lever 36 to engage the power feed. When the machining operation reaches a predetermined point stop-screw 48a releases the stop lever 44, the feed lever 36 is released, switch 46a returns to its initial position and the motor 35 is reversed effecting rapid return of the turret 11. Near the end of this return movement a follower 110 is actuated by a bolt 111 which releases the turret clamps 52a and the turret is indexed by one of the indexing pins 122. The indexing of the turret is transmitted to the positioning cylinder and the star wheel 66 which actuates the switch 73 which effects recommencement of the operating cycle. The forward movement of the turret effects relocking of the turret. The sequence is repeated until the operation cycle has been completed whereupon a dog 84 on the cylinder 58 actuates a switch 85 to stop the machine. Electrical circuits for the machine operation are described.
