Title: Improvements in dough-working apparatus
IPC: A21C3/04
Filed: 1920-10-06
Abstract: 164,276. Halvorsen, N. Oct 6, 1920. Dough-working apparatus.-In a dough-working apparatus for flat cakes or the like, the dough is carried between two flour-coated cloths, both of which travel in the same direction, and is rolled by a roller which moves transversely across the upper cloth. The dough receptacle 1, Fig. 1, is provided with two rollers 2, 3, the speeds of which may be varied and which revolve in opposite directions, the roller 3 having grooves in its periphery to carry the dough to a serrated scraping knife 6 which removes the dough and enables it to be squeezed, in the form of a wide band, through the slot 7. The dough is carried by the cloth 8 to a second cloth 10, Fig. 2, so that the dough travels between the cloths and is rolled by a reciprocating roller 13 operating across the path of motion of the dough. A supporting board 14, adjustable by means of the screw 18, spring 15, and levers 16, 17, regulates the thickness of the sheet of dough which is finally carried by the cloth 8 to devices which convey it to the oven. The amount of dough removed from the roller 3 is varied by adjusting the knife 6 toward or away from the roller; and the thickness of the band issuing from the slot 7 is varied by a regulable plate which may partially close the slot. To prevent the dough from sticking to the cloths 8. 10, flour is provided by the flour troughs 11, 12 respectively.

Title: Improvements in and relating to railway rail clamps
IPC: E01B9/48
Filed: 1955-10-05
Abstract: 781,406. Securing railway rails. DEENIK, J. F., and EISSES, J. A. Oct. 5, 1955 [Oct. 7, 1954], No. 28354/55. Class 104 (2). A railway rail fastening clip comprises a length of steel rod bent to a U shape 9 and shaped to provide a tang for insertion into an aperture 18 in a rib 15 formed on a chair 13 with the arms extending straight for a portion of their length and then being bent backwards and above at 10 so as to extend a substantial distance beyond the central portion of the U shaped bend and then being bent at 11 towards the plane of the U-shaped bend 9 so as to form abutment faces 11a at right angles to the plane. The arms 10 diverge towards their outer ends, Fig. 2. The chair plate 13 has ribs 15, one on each side of the rail 12 and the rail 12 is held in position by inserting the tang in an aperture formed by a gap 18, Fig. 5, in the rib 15 and by pressing the diverging arms 10 together with a special tool so that they pass through a narrow part of the gap 18 in the rib 15 and then driving the fastening home. Once the fastening has been driven home, the arms 10 spring outwards and their end faces 11a engage the upper edge of the rib 15 on each side of the cap and thus prevent removal of the fastening and at the same time bear on the rail flange. In the arrangement shown in Fig. 7, the arms 10 of the fastening are parallel and when the fastening is driven home the temporarily outwardly splayed arms 10 pass along the end faces of the rib 16 to spring inwardly when the fastening is fully home. A thin sheet of rubber 14 or other suitable resilient material is placed between the rail 12 and the chain plate 13.

Title: Rolling Mill
Inventor: O'BRIEN JEREMIAH WAGNER
IPC: B21B31/02
Filed: 1965-07-05
Abstract: 1,155,013. Rolling. UNITED ENG. & FOUNDRY CO. 5 July, 1966 [5, July, 1965], No. 28443/65. Heading B3M. [Also in Division G3] A rolling mill includes screws 42 positioned between work roll chocks 17 and 18 for setting the initial roll gap, and an additional screwdown 27, acting on the upper backing roll chock 21, for adjusting the intial roll gap. Such adjustment may be made in response to the outputs from load cells 46. Each chock 17 houses a pair of screws 42 rotatable in fixed nuts 41 and bearing against load cells 46. A spring 48 beneath each load cell protects the rolls from shock loads when the trailing end of a rolled strip leaves the mill. Each screw is rotatable, through pinions 43-45, from a rod 51 and rod 55. A pair of electric motors on top of the mill housings rotate the four screws. The conventional screwdown 27, which is driven by a further pair of motors, can conveniently be replaced by an hydraulic mechanism disposed beneath the lower chock 19. The output from load cells 46, Fig. 5, is fed to an amplifier 61 where it is converted to a thickness value, and then to an amplifier 62 where the value is compared with a reference value, and any difference fed along line L to a servo valve 65 which controls the screwdown 27. The pressure urging the work rolls together is thus maintained at a value which exceeds the rolling load by a predetermined amount. Reference thicknesses T 0  or T 1 , corresponding to the no load gap and normal rolling gap, are fed together with a modified value of the load in the cells 46 to an amplifier 72 which controls the position of the screws 42. Any resulting pressure difference in the cells 46 leads to a corrective change of the roll gap by the screwdown 27. An additional thickness control system which measures the thickness of the rolled strip can be used to monitor the control system for maintaining the pressure constant.

Title: Improvements in and relating to controllable electric coupling elements
IPC: H03K17/84
Filed: 1966-06-27
Abstract: 1,148,463. Magnetic storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 27 June, 1966 [1 July, 1965], No. 28654/66. Heading H3B. [Also in Division H1] Apertured conductors 12 and 13 are separated by and coated with insulation, over which is a magnetic thin film with an easy direction of magnetization preferably corresponding to that produced by a current in conductor 12 and with a residual magnetisation in the easy direction substantially equal to the saturation level. After a pulse in conductor 12 has saturated the film a further pulse in the same direction merely drives the film along the generally flat portion of its hysteresis curve, without generation of a significant voltage across conductors 12, 13. When a current in the opposite sense, below the value required to effect a reversal of saturation, is passed through conductor 12, together with one in conductor 23, the film magnetization is switched or preset away from the easy direction, and if the rate of increase of the currents is small enough, there is no significant output. When, however, a large current is then quickly applied to conductor 12 in the usual sense, and that in conductor 23 maintained, a voltage pulse of significant magnitude appears across conductor 13 and constitutes an output. When the currents are removed the film returns to its usual magnetization. Alternatively the magnetic film may have a circumferential easy direction, and the current in conductor 23 be removed at the end of the preset operation. Coupling elements of this kind may be arranged to operate in a thin film memory, conductor 13 being integral with word line 31. Many such combinations of coupling element and word line may be arranged in a sheet, the conductors 12 of a number of coupling elements being energized together in series. These word sheets may be stacked vertically, with several coupling elements controlled by one conductor or group of conductors 23, so that they form a matrix, and a particular coupling element can be energized by the appropriate conductors 12 and 23. If the single conductors 23 are replaced by a plurality of conductors, selection may be instead by having a unique combination of components specify each coupling element. In the selected coupling element they conduct in the same direction, and their efforts combine, but in unselected coupling elements they oppose one another and give a much lower excitation which is insufficient to concern output. A related coupling element with parallel input and output conductors passing through an aperture in a control conductor, is described in outline. In this embodiment excitation currents large enough to reverse the residual magnetism of the film may be employed.

Title: Improvements relating to steam clothes presses and ironing machines
IPC: D06F71/32
Filed: 1933-10-17
Abstract: 427,189. Ironing-presses. POWE, H. L., and LUNGLEY, Ltd., L., la, Downs Park Road, Dalston, London. Oct. 17, 1933, Nos. 28723 and 29711. [Class 138 (ii)] In an ironing-press means are provided for indicating or preventing unauthorized premature termination of the closed condition of the press. In the form shown in Fig. 1, the closing movement of the press mechanically closes a switch 1 to complete a circuit through a slow-acting relay 2, the working duration of which is equal to the normal time for which the press is required to be closed. The relay 2 closes switches 4, 3, of which the switch 4 completes a circuit through a visible or audible indicator 7 indicating the commencement, continuation and termination of the normal press-closed period. The switch 3 is arranged in circuit with a normally open switch 9 and a remote visible or audible indicator 8. As the press opens the switch 9 automatically closes, a mechanical connection being provided between the switch and a moving part of the press or its operating mechanism ; if such press-opening occurs before the end of the time predetermined by the relay, the indicator 8 is operated. Clockwork or other control means may be substituted for the relay. In the form shown in Fig. 2, the press is locked in closed position for a predetermined time. The switch 1 and relay 2 operate a switch 4 to energize the signal 7 as in the other modification, but the switch 13 energizes a circuit including a solenoid 11 which operates the mechanical locking element 10. In case of emergency the circuit through the solenoid 11 can be de-energized by manually opening a switch 14; such action, however, simultaneously closes a switch 15 in a circuit which includes a remote signal 17 thereby giving an indication of the premature unlocking of the press.

Abstract: 1392348 Vibratory conveyers HAUNI-WERKE KORBER & CO KG 20 June 1972 [29 June 1971] 28837/72 Heading B8A [Also in Division G3] A vibratory conveyer 1 for supplying tobacco to the supply containers of one or more cutters has means for regulating the flow through take off apertures 4a ... 4c to a maximum or a minimum value in response to signals from a device which senses the level of tobacco in the or each container. Each container (6, Fig. 1, not shown) has photo-electric detectors at three levels;those at the two lower levels are associated with logic circuits (Fig. 3, not shown) whereby when the tobacco is below the lowest level an electro-pneumatic actuator 9 is driven fully in one direction and when the tobacco is above the second level it is driven fully in the opposite direction. At intermediate levels the actuator stays in its last position. As shown the actuator operates deflectors 11, 12 but alternatively (Fig. 4, not shown) the deflectors are fixed and the actuator moves a shutter across the aperture. The deflectors for successive apertures are staggered as shown to collect tobacco from different parts of the stream. The upper of the three level detectors causes a shutter to close the aperture completely and operates, e.g. if its associated cutter stops.

Filed: 1946-09-30
Abstract: 619,545. Fluid blast switches. ETABLISSEMENTS MERLIN & GERIN. Sept. 30, 1946, No. 29102. Convention date, Oct. 3, 1945 [Class 38 (v)] An oil circuit-breaker has an explosion pot 3, which by compressing springs 13, 14, can move under the effect of the pressure generated in it by the arc. Fig. 2 shows the position of the explosion pot at the moment when the pressure has reached its maximum immediately after the separation of the contacts 1, 2. A relief port 5 is open to limit the pressure generated and to provide a blast of gas past the fixed contact 1, whilst the transverse blow-out orifices 6 to 9 are masked by the moving contact 2. As the current in the arc drops, the pressure falls and the pot springs back to close the port 5 and open several of the orifices 6 to 9, thus enabling the residual pressure to create a blast across the moving contact and so extinguish the arc at the current zero. The above action may be obtained when using a solid gas evolving material instead of oil. In a modification, Fig. 3 (not shown), the explosion pot has axial blow-out orifices. A method of mounting the explosion pot, Figs. 5, 6 (not shown), provides for its easy removal by releasing a catch and turning the pot so that neck portions of special bolts disengage from slots in the supporting plate. In a further modification, Fig. 4 (not shown), a blow-out orifice is provided by a hollow moving contact instead of by holes in the explosion pot, the final extinction of the arc taking place when the return of the pot causes the moving contact to be flooded with oil.
