Title: Improvements in and relating to dough handling machines
IPC: A21C5/08
Filed: 1949-04-21
Abstract: 664,549. Machines for dividing and rolling dough. RUBURY, J. M., HOY, F and HAMMOND ENGINEERING CO., Ltd. April 19, 1950 [April 21, 1949], No. 10584/49. Class 87(ii) The platen 8, ring gauge 6 and cutters 10 of a dough dividing and rolling machine are power operated by means of a crank c, connecting rod b and lever a. The crank is connected to the source of power by a clutch and its rotation is manually controlled and limited to steps of half a revolution between upper and lower dead centres. During motion from upper tc lower dead centre the cross-head 4 and with it the ring gauge 6, platen 8 and' cutters 10 are forced downwards to shape dough resting on a plate 16 into a flat circular slab.. The cross-head 4 acts on the platen 8 through a T-lever 9; the dough cutters 10 are advanced by studs 11 and the ring gauge by springs 7. As the crosshead approaches its lowermost position the long arm 18 of the T-lever contacts a fixed cam surface d, Fig. 8, which causes it to move in an anticlockwise direction and thus disengages the short arms 13 from the surfaces 15 of the platen 8. The platen, now unrestrained, rises under the influence of springs 12 leaving the cutters 10 in contact with the upper surface of the dough slab and the ring gauge in contact with the plate 16. Further downward motion of the cross-head 4 forces the cutters 10 through the dough. At this point clutch 19, 20 is engaged to transmit orbital motion to the bed 17 through the shaft 22, spiral gears 23 and cranks 233 to roll the dough into spheroids. The bed is resiliently mounted by means of springs t. After this operation, the crank c is caused to move from bottom to top dead centre, and the cross-head 4, ring gauge 6 and cutters 10 rise. The long arm 18 of the T-lever 9 contacts in its upward motion a resiliently mounted cam surface v, Fig. 8, which, as the cross-head approaches its uppermost position, causes the T-lever to move clockwise and the short arms 13 to re-engage the surfaces 15 of the platen 8. The intermittent motion of the crank c is provided by a manually controlled rotary key clutch between the crankshaft e and a concentric constantly-rotating gear wheel h. The rotary key g carries a lever k which is pressed into the "engaged" position by a spring l and is disengaged every half cycle when it abuts against either of the two parallel detents m, n. By means of linkages o, q and hand lever p either of the detents m, n can be moved into the path of the lever k as the other is withdrawn. The bridle 28 of the machine supporting the shaft 1, stem 5 &c. is pivoted at 29 and retained in closed position by a bolt 30. The bolt 30 can also be used to retain the bridle in the inclined (open) position by passing it through holes 31 in the bridle which registers with a hole 32 in the lower frame. The lever a is detachably connected to the end of the connecting rod b by a pin a<SP>1</SP>. The end portion b<SP>1</SP> of the rod b is forked to provide support for the pin a on either side of the lever a and thus ensure its easy withdrawal.

Title: Process for the purification of abietic acid and for producing pure abietates or abietic acid
IPC: C09F1/00
Filed: 1925-04-24
Abstract: 244,980. Dupont, G. H. April 24, 1925. Abietic acid and salts.-In a process for the production of pure abietic acid and abietates, the crude acid is dissolved in a solvent, is transformed into an insoluble salt and is separated from the mother-liquor, as by pressure. ln a preferred process, the crude acid is mixed with alcohol, or is formed in alcohol by heating an alcoholic solution of colophony with hydrochloric acid. The mineral acid is then neutralized, and an amount of an alkali such as soda, potash, ammonia or the corresponding carbonates, sufficient to neutralize a fourth part of the abietic acid, is added. Acid salts of abietic acid are precipitated and the whole is subjected to pressure in a hydraulic press to remove the mother-liquor which carries the impurities with it. By action of strong acids on the remaining abietates a pure and nearly colourless abietic acid is obtained.

Title: Improvements in the galley mechanism of typographical composing and casting machines
IPC: B41B11/72
Filed: 1921-04-13
Abstract: 174,879. Hart, H., (Mergenthaler Linotype Co.). April 13, 1921. Galley-mechanism for type-bar-making machines. -In a type-bar-making machine, galley mechanism is provided to act on the. slugs as they are delivered from the mould to cause them to pass to the galley with either end foremost, as desired, so that Hebrew, Arabic &c. or English slugs may be stacked in the same galley, or the galley may be replaced by an ordinary English galley. The slugs X are cast in the mould A and are ejected through an opening A<6>for delivery to the galley B, which is supported on arms B<2> attached to the machine frame. Hebrew slugs, on leaving the mould, are acted on by an adjustable stop E arranged to engage the slug near its upper lefthand side, and by an adjustable plate F' engaging the lower right-hand side of the slug. The plate F<1> is carried by the usual reciprocating stacking. lever F, Fig. 1, and is held in adjusted position by a set-screw. The slug is thus delivered on its side into a shoot C attached to a plate C<1>which is detachably mounted on the machine frame. The shoot is twisted at a part of its length to turn the slug on to its edge, in which position it is delivered to the galley, where it is stacked against a resistant B<1> by a plate D<2> carried by a reciprocating arm D. The stop E consists of an L-shaped piece having a slot in its vertical side to enable it to be adjusted on a screw in the plate C<1>. For English slugs the stop E is lowered to engage the bottom of the left-hand side of the slug, and the plate F<1> is set at a forward inclination, so that the slugs are delivered to the galley upper end first. In the modification shown in Fig. 1<a>, the shoot is made in two parts, C<4>, C<5>. the former being carried by the plate C' and the latter by one of the galleybrackets B<2>.

Title: Improvements in or relating to control systems for electric motors
IPC: B66C13/50
Filed: 1956-04-10
Abstract: 788,702. Control of D.C. motors. SQUARE D CO. April 10, 1956 [May 3, 1955], No. 10850/56. Class 38 (3). A crane motor 10 is controlled by a master switch 20 having five hoisting and five lowering positions, the control circuit comprising lowering and hoisting contactors 11, 13, as well as dynamic braking contactors 15, 17, associated with resistors 58, 59. Accelerating contactors 19, 23, control armature resistors 67, 69 whilst main contactors 25, 27, have contacts 81, 86, in the motor circuit. A current-responsive coil 70 provides a limitation for the highest speed in the lowering direction when heavy loads are encountered. When the controller 20 is moved from its " off " position to the first hoisting position, contacts 42 close to energize coil 25 where by contacts 81, 82 are closed. The closure of contacts 28 on the controller actuates the hoist contactor 13. A circuit is completed from line L1 through contact 53, series lock-out coil 60, limit switch contacts 94, armature 10, limit switch contacts 92, and series field winding 14, a shunt circuit being formed through coil 70 and braking resistors 58, 59. The motor circuit is completed through series brake coil 35 and starting resistors 67, 69. A shunt lock-out coil 50 is connected in parallel with the motor circuit. Normally, the current drawn by the motor 10 passing through the lock-out coil 60 causes the armature 76 to prevent the shunt coil 50 from moving its armature 68 and thereby opening contacts 52. The load is moved at low speed in the hoisting direction until the limit switch 90 is tripped by the crane hook, for example. The opening of contacts 94 deenergizes the series lockout coil 60 and permits the armature 68 to move under the influence of coil 50 so opening contacts 52 and de-energizing the no-volt coil 40. This operation disconnects the motor from the line, it being necessary to return the master controller to the " off " position to re-set the no-volt relay. Another attempt at hoisting will re-energize the coil 50 so that contacts 52 are re-opened and the control circuit is de-energized. Movement of the master controller to the second hoisting position additionally closes contacts 30 to energize contactor 17 and remove resistor 59, so decreasing the proportion of current passing through coil 70 and allowing an increase of motor speed. The limit switch 90 and lockout relay 49 are actuated when the hoist limit is attained to effect operation as on the first hoisting notch. When the limit switch is tripped, the field winding 14 forms a low-resistance shunt for the armature so that the motor is brought quickly to rest and oscillation of the hook is prevented. The shunt coil 50 is operative only during the hoisting operation.

Filed: 1946-04-09
Abstract: 617,263. Television. LORD, A. V., and PYE, Ltd. April 9, 1946, No. 10852. [Class 40 (iii)] In a television receiver the video waveform comprising both picture intelligence and synchronizing pulses is fed to the line time base oscillator valve which is so biassed that only the synchronizing pulses cause the valve to operate. The arrangement of Fig. 1 comprises a line saw-tooth generator including the line oscillator valve V1 across the cathode resistor R of which is applied the video waveform, the synchronizing pulses being in the negative sense and the operating conditions being such that the valve is triggered by the synchronizing pulses only. In a modification, Fig. 2 (not shown), the cathode of the line oscillator valve is connected to the cathode of a video amplifying valve, the resistance R which in this case is common to both valves being shunted by a capacitor to provide the necessary high frequency compensation for the video amplifier. In a further modification, Fig. 3 (not shown), the line oscillator valve and video amplifier valves are combined in a single envelope such as a double triode valve having separate grids and anodes but a common cathode. Specification 478,151 is referred to.

Density separators.-Relates to a separating- machine of the kind in which the grains of different masses are subjected to the simultaneous action of centrifugal force and a current of water acting in opposite directions. A conical member 8 secured to a shaft 4, and provided with vanes 9, 10, rotates in a fixed vessel 3 to which water charged with the substances to be sorted is led by a pipe 14, and which has a discharge pipe 15 at its lower end. The vanes 10 may be connected together by a disk 11 provided with a series of apertures which coincide as regards position with discharge apertures 12 in the vessel 3 leading to a settling chamber 13. Suction is produced in this chamber by a pipe 16 leading from the discharge pipe 15 and may be regulated by a tap 17. The lower end of the member 8 is so formed that, at the constricted passage round the outer edge thereof, the flow of water preponderates while towards the centre the centrifugal force predominates. The neutral zone where grains of the mass for which the velocity of rotation is adjusted are in equilibrium is in the neighbourhood of the diecharge openings 12. Liquid is pumped from a trough 20, in which the level is constant or controlled, to a hopper 25 into which the substances to be sorted are discharged by a distributor 26. The water emerging from the apparatus may be discharged into the trough 20 or into a drain, in which case the trough is fed with fresh water. Several of the separators may be arranged in series.
