Dough dividing and working machines; rolling - machines. - In a dough-dividing and - working machine wherein dough placed within a frame 32 is compressed by a presser head 14 and divided by knives 39, held adjustably in said head, into sections, each section formed thereby being provided with a working pin 26, the various operating devices are controlled by a single cam shaft 41, geared to a driving shaft 1, which also has means for throwing itself out of gear automatically after each complete revolution, an entire cycle of operations being carried out during such revolution. The frame 32 is guided vertically in the machine frame and is suspended on springs tending to pull it away from a bottom plate 30, which is supported on a table comprising a frame 24 and a plate 25, the frame 24 resting on two rotatable discs 23<1> controlled by crank pins 23. These cranks 23 are driven from the main shaft 1 through a clutch 17 and bevel wheels 19, 21, while the pins 26 for working the dough are mounted in the plate 25 and are brought up through apertures in the plate 30. The presser head 14 is also guided vertically in the machine frame by a tubular shank 13, while another shank 15<1> guided within the shank 13 holds the dough-divider 15, which is fitted with knives 39 connected in honeycomb fashion and working in corresponding slots in the head 14. These shanks are operated by rocking levers 11, 12 from cams 6, 7 mounted on the shaft 41 which is geared to the shaft 1 through a worm and worm wheel 4, 5, the main shaft being operated by a pulley 3. The plate 25 is normally locked by a latch 31 so that the pins 26 occupy a central position relative to the sections of dough, the latch co-operating with a cam 33 connected to the cam 7, while the frame 32, when applied to the plate 30, is locked in this position by a shackle 34, which is released by a lever 35 co-operating with a tappet 36 mounted on a disc 8 fixed to the shaft 41. In operation, a lever 2<1> is moved to engage the shaft of the worm 4 with the driving pulley 3 by means of a clutch 43, which causes the shaft 41 to rotate to lower the head 14 and knives 39, after which the plate 25 is released from the cams 33. At the same time, the clutch 17 is coupled to the shaft 1 by a lever 28 co-operating with a cam 29 secured to a disc 9, also mounted on the shaft 41, to operate the cranks 23 and pins 26. When the lever 28 is released from the cam 29, the cranks 23 are brought to rest. and the plate 25 is centred and locked. The dividing-knives are then retracted into the presser-head and the whole lifted out of the frame 32, after which the lever 35 is operated to release the frame, which is lifted by its springs leaving the dough sections behind on the table. Finally, the slide 2<1> is operated by a tappet 37 also carried by the disc 9 to open the clutch 43 and arrest the main shaft. The position of the dough-divider and presserhead relative to the working table can be adjusted by milled nuts 16 provided on the cam levers 11, 12.

Abstract: 807,411. Stabilizing and manoeuvring ships. McNAB, N. S. Oct. 16, 1956 [April 10, 1956], No. 10904/56. Classes 113 and 114. [Also in Group XXIX]. Apparatus for controlling stabilizing fins, for retarding pitch or roll, or rudders comprises a hydraulic unit or units, e.g. hydralic units 18, pivotally connected to a flanged bush 16 arranged to transmit rotary movement to a stock 2, controlled by a rotary valve 24 having a control valve member 28 concentrically disposed within a sleeve member 27. The sleeve member is connected by a link 42 to the bush 16 to follow the angular adjustment of the stock to cut off and lock the pressure fluid within the hydraulic cylinder 18. The control lever 40 of the control valve member 28 may be regulated manually or in the case of stabilizing fins may be gyroscopically controlled in which case the lever 40 is connected by a link 41 to a disc 43 mounted on a shaft 44 intermittently rotated by a motor 47 through a ship clutch 45. A member 48 having two teeth 180 degrees apart is mounted on the shaft 44 and the teeth engage a pawl 49 mounted on member 50 adjustable concentrically with the shaft 44. The roll-responsive gyroscope precesses at the commencement of roll and moves the pivoted switch lever 52 to engage one arm of U-shaped member 55 to complete the electrical circuit and energise the solenoid 51 which releases the pawl 49 to permit half rotation of the shaft 44 and angular adjustment of the lever 40 to adjust the fin 1. After the initial electrical contact has been made the insulated end 56 of the lever 52 moves the U-shaped member 55 and breaks the electrical contact until the precessing movement of the gyroscope effects movement of the lever in the opposite direction to complete the circuit through the other arm of the U-shaped member. The time period of the fin movement is regulated to less than the time period of roll of the vessel. Two valves 24 as shown in Fig. 4 for adjustment of port and starboard stabilising fins may be provided, and the fins may be withdrawn into a housing in the hull by hydraulic units.

Abstract: 688,244. Welding by pressure. ANCIENS ETABLISSEMENTS MALBER. May 10, 1951 [May 15, 1950], No. 10999/51. Class 83 (iv). [Also in Group II] In electrically welding metals, e.g. band saws, cooling of the weld is so regulated that the cooling curve on a time-temperature diagram is close to and beneath the S-curve, i.e. the curve of isothermal transformation. The rapid cooling caused by the water-cooled or other jaws of the welding machine may be checked as required by passing current through the weld or by the action of a hot fluid jet or by both. The fluid may be neutral or reducing, e.g. a flame of combustible gas, to protect the work from oxidation. Fig. 1 shows the cooling curve R for steel with 2 per cent of chromium, the cooling being checked at 330‹ C. until the weld-treated metal has a uniform temperature. For 75 carbon steel cooling is checked at about 300‹ C. In cooling from a welding temperature of, say, 1500‹ C. cooling may also be checked at about 800‹ C. to allow the temperature of the treated metal to become uniform. Cooling from 800‹ C. is then regulated as before. If desired, the weld can be subjected to a subsequent tempering by passing current through it and preferably applying a flame.

Abstract: 1343071 Pulse radar SIEMENS AG 27 April 1971 [28 April 1970] 11516/71 Heading H4D A stereoscopic display for an electromagnetic wave pulse echo system includes a transmitter antenna performing line scans of the terrain, the two picture screens being provided with horizontal and vertical deflections corresponding the echo azimuth and elevation as measured at the antenna site wherein extra horizontal deflections are added to one screen and subtracted from the the other which are proportional to the ratio of the effective stereoscopic base length to the target range measured from the antenna site. At every transmitter pulse S1 is closed momentarily, charging capacitors Cl to one half of Ub representing the base length b. When S1 is opened each C1 discharges through R1 and on reception of an echo S2, S3 are closed transferring the instantaneous voltage on to capacitors C2 its value being approximately b/r, where r is the actual range. This voltage is supplied to the horizontal plates of the two CRT displays B1, B2 with the normal azimuth deflection voltage Up to deflect the indication by equal amounts in opposite directions. The two pictures then appear as if they were produced by receivers displaced laterally by an amount b (Fig. 1, not shown). B1 is viewed by the left eye and B2 by the right thus producing a stereoscopic effect. The display may be used in an aircraft where the displays are fed by optical fibres to the pilot's helmet, or the screens may be viewed by polarized or coloured spectacles. The transmitter may be a linear phased array scanned by frequency modulating the transmitter or if lasers are used the beam is scanned by mirrors or prisms. Artificial echoes having adjustable delays may be incorporated to provide range markers and there may be provided means for altering the range sensitivity, i.e. near and far fields.
