Abstract: 952,527. Moulding dough. SORENSEN BAKERY EQUIPMENT Ltd. Nov. 29, 1962 [Nov. 30, 1961], No. 43819/61. Heading B5A. A dough piece is sheeted, coiled, sheeted again, then coiled and delivered to a receptacle for baking. This ensures that the second sheet is symmetrical about lateral and longitudinal axes. Cross grained dough pieces can be produced by changing the direction of travel of the dough piece to a new direction at right angles after the second sheeting occurs. Apparatus for carrying out the process comprises (Fig. 5) sheeting rollers B, a conveyer b, a coiler b<SP>1</SP>, a further conveyer b<SP>2</SP> travelling at right angles to the first, delivering the dough to more sheeting rollers B<SP>1</SP> and a coiler b<SP>4</SP> on to a conveyer b<SP>3</SP>, through a shaper C and into a baking tin. A modification (Fig. 6) sheets the dough at D, coils it at d<SP>1</SP>, passes it through sheeting rollers D<SP>1</SP> on to a conveyer d<SP>2</SP> where it is flipped on to conveyer d<SP>3</SP> travelling at right angles to the other two conveyers, where the dough is coiled and shaped before passing to a baking tin.

Title: Improvements in or relating to swivel bending machines
IPC: B21D5/04
Filed: 1969-08-29
Abstract: 1,240,396. Angular bending. REINHARD MASCHINENBAU G.m.b.H. 29 Aug., 1969 [5 Sept., 1968], No. 43157/69. Heading B3E. [Also in Division G3] A bending machine comprises a pivoted bending beam 4, a vertically displaceable top beam 6 and a locating member 11 reciprocably displaceable by an electric motor rotating a spindle 16 in a nut 19, the motor being under the control of electronic control means to de-energize it when the locating member 11 is located in a selected one of a plurality of predetermined positions. In operation the top beam is raised to allow a workpiece 7 to be introduced between bottom beam 3 and top beam 6. The top beam is then lowered so as to rigidly clamp the workpiece between it and the bottom ram, whereupon the bonding beam 4 is pivoted about its axis 5 through a predetermined angle to bend the edge of the workpiece protruding through beams 3 and 6. To control the displacement of the locating member 11 to a predetermined position, e.g. E (Fig. 6) in order to carry out a particular programme step in its displacement, the locating member begins from a starting position A, A 1  nearest the required position E. The distance of the position E from the pivot part 5 is set by means of a coding switch 32, associated with the relative programme step, the valve being fed into control device 30. Triggered by an output from control device 30 the locating device is moved from switch A 1  towards the position E. As switching cam 25 passes switch A, an electronic counter 43 is adjusted by the control device 30 to a value equal to the distance between switch A and position E 1 . At the same time the counting mechanism 43 starts by counting the fed-in value. The counting pulses are passed by the pulse transmitter 41 to the counter 43 until the zero position is reached in the counter at which point the locating member 11 has reached point E 1 . At the same time the magnitude preset by a coding switch is automatically fed to the counter, whereupon the motor 22 is switched to slow speed until the point E is reached and the counter 43 again registers zero.

Bistables h 1 -h n  in the cage are switched by elements 11 along the path. The desired halt station is entered in units 12, 16 and unit 13 senses cage position by the state of the bistables. If the cage is at one side of the selected halt transmitter 14 emits a first signal, if the cage is the other side it emits a second signal and if the cage is at the halt station it emits a third signal. The three signals are of short duration and different frequency and control the cage drive machinery to move the cage to the halt station.

Title: Improved synchronous induction motor rotor
IPC: H02K19/14
Filed: 1960-12-16
Abstract: 914,913. Squirrel-cage constructions. ALLISCHALMERS MANUFACTURING CO. Dec. 16, 1960 [Dec. 31, 1959], No. 43476/60. Class 35. In a synchronous induction motor rotor 12 having adjacent salient poles 16 separated by longitudinal axial grooves 17 containing non- magnetic electrical conducting material, an extension 25 of laminated magnetic material is disposed at least at one end of the rotor core 14 and is magnetically separated therefrom by separator 30, preferably of insulation but which may be copper or aluminium, to reduce the leakage flux entering the extension during synchronous operation. Winding slots 32, 27 in the separator and extension, respectively, are aligned with slots 18, 35 and grooves 17 of the rotor core. Slots 18 of adjacent poles are joined by a slot 19 to impede the passage of flux from one interpolar area to another, and define a path in the core for useful flux between adjacent poles. Slots 18, 19, 27, 32, 35 and grooves 17 contain die-cast conductors such as aluminium and are interconnected at each end of the rotor by a ring 41 to provide a squirrel-cage winding. The conductors in the rotor extension 25 are thus in series with those in the core 14, so increasing the rotor impedance and hence decreasing the motor starting current. In a modification, Fig. 4 (not shown), the rotor extension has a radially outer and a radially inner group of winding slots. Reference has been directed by the Comptroller to Specification 771,669.

Abstract: 1,043,600. Projection screens; stands. KNOX MANUFACTURING CO. Nov. 6, 1963 [May 20, 1963], No. 43795/63. Heading G2J. A portable stand for a projection screen has folding legs 13 which are automatically urged from the supporting extended position to the closed or retracted position against the standard 12 when the stand is lifted from the ground. A handle 14 is slidably adjustable on standard 12 and provides a mounting for the screen casing 16 such that the screen pivots through 90 degrees to the operative position when released from the carrying position. Standard 12 comprises a tube 17 in which slides a rod 18 whose upper end carries a bail support 22 engaging a recess 24 in casing 16 in the carrying position. A collar 28 slides on tube 17 and has ears 31 to which are pivoted channel-section leg members 33, while collar 30 is fixed at the lower end of tube 17 and has ears 32 to which are pivoted bracing stouts 35. The legs are urged towards the spread position by torsion springs 38, but a more powerful compression spring 25 within tube 17 below rod 18 bears against arm 41 of each of the pivotal levers 40 whose arcuate arms 43 are therefore urged anti-clockwise against the webs of struts 35 and the legs are held retracted. When its clamping member 21 is freed, rod 18 is driven upwards by spring 25 to release support 22 from recess 24 and the screen swings horizontal, while the springs 37 are then able to extend the legs 33. To store the stand, rod 18 is depressed fully and clamped, and when the stand is then lifted, the legs are retracted by spring 25. In a modification, torsion springs 37 are replaced by second, weaker compression springs 45 below levers 40.
