Title: Improvements relating to "y" flap feed devices for dough-pieces
Inventor: HOPE EWART KENNETH HOULSTON
IPC: A21C9/08
Filed: 1952-10-31
Abstract: 735,649. Feeding dough. PELKMAN BROS., Ltd. Feb. 1, 1954 [Oct. 31, 1952], No. 27411/52. Class 78 (1). [Also in Group VI] In a Y flap feed for bakery installations, the greater part of the movement of the flap is unrestrained but, near its limiting positions, means become effective to reduce its momentum and prevent rebounding. Dough pieces are fed from the handing machine to the Y flap feed 10 which consists of a sheet metal Y flap 20 so pivoted in a shoot 12 that a dough piece 24 passing down the shoot 12 to the left of flap 20 swings it round and causes the next dough piece to pass down to the right and swing the flap back. On emerging from the shoot, the dough pieces are received by a trap having a partition 28 and a pair of flaps 30 which open when two dough pieces rest side by side in the trap. Opening of flaps 30 then delivers the two dough pieces to one of a series of pairs of pockets 34a, 34b mounted on the conveyer of the first prover. Flap 20 is supported on a pivot pin 22 by means of a sleeve 38, closed at one end 40, which leaves a clearance 42 for a metal plate 44 pivoted on pin 22. A pin 48 passes through a slot 46 in plate 44 and through the base 41 of the shoot 12 and a spring 50 encircling pin 48 holds a washer 51 against plate 44 so as to retard the movement of plate 44 relative to the base 41. Stop pins 52, 54, secured on plate 44 near the ends of slot 46, engage the edge 58 of a plate 56, fixed within flap 20, when the flap is near its extreme positions and so plate 44 is moved against the action of spring 50 to reduce its momentum.

Title: Improvements in and relating to electric control systems
IPC: G05F1/00
Filed: 1931-10-02
Abstract: 390,501. Control systems for consuming devices ; phase-changing. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fitzgerald, A. S. ; Warwick Road, Wynnewood, Pennsylvania, U.S.A.) Oct. 2, 1931, No. 27451. Convention date, Oct. 2, 1930. [Classes 38 (ii) and 38 (iv).] The current in an A.C. load circuit 11 such as for theatre lighting, motor starting and other purposes is gradually varied between minimum and maximum values, or may be maintained at a desired value, by control of the phase of the voltage applied to the grids of rectifying valves 15, 16 in series with the saturating windings 13 of a reactor in series with the load. The rate of change of current is adjustable. The apparatus comprises a phase-shifting circuit in which the voltage applied to a grid transformer 17 is the resultant of the voltage in the secondary of a transformer 25 and that across an impedance device 23 which is itself connected in series with a condenser 21 across the supply source 10. The impedance 23 has substantially a resistance characteristic and is a transformer, one winding of which is in parallel with valves 26, 27 the conductivity of which may be progressively varied. The voltage of the secondary winding of the transformer 25 is approximately onehalf the supply voltage and is fixed in phase, hence, as the value of the impedance 23 varies from zero to a maximum the voltage applied to the transformer 17 varies in phase from zero to 180 degrees leading with respect to the supply voltage. Thus the average value of the current passing through the rectifiers 15, 16 varies from a maximum to zero and the load circuit current varies from a maximum value to a minimum. The conductivity of the valves 26, 27 is controlled by a switch 34 which is adapted to charge a condenser 32 to alternative polarities through a resistance 33. This resistance may be varied to determine the rate of change of condenser potential and, the condenser being connected between the cathode and grid of each valve, the rate of change of conductivity of these valves. Thus, closing the switch 34 in either of its two positions with the switch 24 on its right-hand contact produces an appropriate progressive change in the current in the load 11. By opening the switch 34 at any time the load current is caused to remain at the value it has at that instant since the charge on the condenser 32 then remains substantially the same. A variable resistance 22 is provided to give an independent control of the load current. Any circuit of high time constant may be substituted for the circuit comprising the resistance 33 and condenser 32. The resistance characteristic of the primary winding of the transformer 23 may be improved by connecting a resonating condenser 37 in parallel with it.

The whole chimney 11 of a converter 1 is adapted to be raised and lowered out of and into engagement with the converter mouth 4. The chimney 11 communicates with a horizontal exhaust duct 19 above the roof 18 of the building housing the converter, the duct 19 following vertical movements of the chimney. Explosion doors 20 and 21 are provided adjacent the junction of the duct 19 and chimney 11. The chimney is guided by guides 31 and raised and lowered by an hydraulic jack 10 whose piston-rod 28 has a ball 29 engaging a shallow socket 30 on the chimney 11, thus allowing slight lateral movement of the bottom of the chimney. Alternatively, the chimney may be lifted by two or more jacks, pulley blocks or chain blocks. The bottom 12 of the chimney is flared and when lowered engages two sealing rings 5 and 6 on the converter. The lower end of the chimney may be moved to and fro by an operating drive 36 and rod 38 to enable the chimney to seat itself on the sealing rings 5 and 6. The space 13 between the rings is fed with nitrogen from a pipe 7 which passes through the trunnions 2 mounting the converter, the rings 5 and 6 and the lower end of the chimney being so constructed that the greater part of the nitrogen escapes downwardly as shown by the arrow 15 to prevent ingress of air. Further nitrogen is injected above the ring 5 from. a pipe 14 to cool the converter gases. The chimney 11 is lined with bricks immediately above the converter mouth 4 to form a foaming chamber 16 and the lower part of the chimney is cooled by a water jacket 17 or by cooling coils.

Abstract: 712,640. Embossing; printing-processes. ANKER-WERKE, AKT.-GES. Nov. 23, 1951 [Dec. 1, 1950], No. 27547/51. Class 100 (2) In a machine for printing or stamping on vouchers, tickets, receipts, &c. of the kind including an adding means, a pair or pairs of co-acting printing elements, e.g. type drums, A, B, C, and impression rollers 9, are driven with a gear ratio in relation to each other so that a single printing in a particular printing area occurs although the elements rotate more than once during the passage of the voucher past each pair of elements. In the machine shown, three printing drums A, B, C are coupled by gearing 38, 39, Fig. 6, and driven from a common source 52 which is energized by the lifting of a lay or registering device 36 by the voucher. Drum B carries a series of typewheels 21 for printing the date, and drum C carries both type-wheels 22, for printing an identifying number, and a printing block 22a, for printing invariable matter. The type-wheels 21 and 22 are set by rotating knobs. Drum A carries type-wheels 20 which are set by gearing 27-32 in response to an amount or other selected matter. After setting, the gearing 32-28 is brought out of engagement with the gear wheel 27, the type-wheel 20 is held in set position, by a pawl 35, and the gearing 32-28 is held by pawls 33, 34. Impression rollers 9 which coact with the typewheels have impression zones angularly displaced from each other to take account of the distance between the separate printing positions and the position of printing on the voucher. The gearing between the drums A, B, C and the rollers 9 is in the ratio 2:3 so that two rotations of the drums are required before an impression zone coacts with the type-wheels. The impression rollers 9 are mounted on shafts 8 journalled at one end in a frame 55 having bent end portions 56 by which it is rockably mounted on pins 57 secured in side frames of the machine. These pins are located in the plane of pairs of gears 38, 54, which couple the rollers 9 and the drums A, B, C so that they remain in engagement when rollers 9 are raised by cranks 10 to effect impression. Cranks 10 are urged to effect impression by springs 13 when a bar 15 is reciprocated by a lever 63, Fig. 6, which is rocked by a cam 45 in the drive mechanism.
