Abstract: 1,059,979. Laminating dough. BURGESS ENGINEERING (STOKE-ON-TRENT) Ltd. June 28, 1965 [April 4, 1964], No. 13978/64. Heading B5A. In a method of laminating dough, a strip 11 of dough from an extruder 10, is fed on to a reciprocated belt 12 driven through a drum 14 by a reversible electric motor (not shown). The motor is controlled by a timing disc 18, which is driven from drum 14 by a belt 16 and sprocket 15 and 17, and which carries trip members 19. As the belt is driven in one direction the disc 18 rotates until one of the members 19 contacts a first switch 20 which reverses the motor which thus drives the belt in the opposite direction. Disc 18 thus rotates in the opposite direction until the other of the members 19 contacts a second switch 20, thus causing the belt to be driven back in its original direction. By adjusting the positions of members 19 in holes 181 and 182 in the disc the length of travel of the belt in each direction may be controlled. In an alternative embodiment the extruder may be reciprocated by such a reversible motor whilst the belt remains stationary. If required a pro-formed sheet of dough may be used.

Title: Improved reaction chamber
IPC: H03M1/00
Filed: 1946-05-10
Abstract: A chamber for carrying out chemical reactions, such as the production of metal by thermal decomposition of compounds in the vapour phase (see Group II), comprises a rigid, gasimpervious shell, preferably of refractory material such as stainless steel or porcelain, having an internal lining of calcium beryllate.  The lining may also include beryllia in amount between 4 and 5 parts for each part of calcium beryllate.  The mixed compounds are formed into a slurry and applied to the shell as a heavy coating which is air dried, fired with a gas burner and then baked for about 5 hours at 1400 DEG  C.  The calcium beryllate is suitably prepared by adding potassium hydroxide solution to beryllium nitrate solution until the first formed precipitate redissolves, adding hydrochloric acid until a precipitate first appears, then adding a solution of calcium chloride.  The calcium beryllate precipitate so formed is filtered, suspended in water, again filtered and then washed.ALSO:Metals are prepared by thermal decomposition in the vapour phase of compounds thereof, the decomposition being performed in a reaction chamber comprising a rigid gas-impervious shell having an internal lining of calcium beryllate (see Group III) wherein the metal is deposited at a temperature above its melting point. Uranium may be prepared from impure uranium by passing a stream of hydrogen containing idodine vapour at low pressure. e.g. 10-3 m.m. mercury, over impure uranium heated to about 1000 DEG C. Vaporized uranium iodide passes to a decomposition zone heated to about 1470 DEG C. where uranium is deposited and from which it is recovered in massive form.  Inert gases may be used instead of hydrogen or iodine vapour alone may be used.

Filed: 1950-06-12
Abstract: 688,707. Control of two motors. WESTERN STATES MACHINE CO. June 12, 1950 [June 14, 1949], No. 14655/50. Class 38 (iii) [Also in Group II] The shaft of a centrifugal separator depends from a two speed induction motor MM which drives the separator in one direction during charging and separation. During the discharge of the separator the motor MM and the separator are driven in the opposite direction by a low constant speed motor DM mounted on the motor MM. The motor MM drives one member 40 of a clutch DC by means of belts 56 worm 49 and wheel 48. Air may be supplied to expand a flexible band 42 on the member 40 to engage the other clutch member 36 which is mounted on an extension 34 of the shaft of the motor MM. The separator is rotated from rest by the motor MM to a low speed for charging, and then the speed is increased to a high speed for separation. After separation the motor MM is switched to low speed, the regenerative braking of the motor being assisted by applying a brake to the separator. The motor MM is de-energized, the brake is released, the motor DM started and the clutch engaged to rotate the separator in the opposite direction at low speed. The clutch may be engaged before rotation of the separator ceases in which case the clutch first acts as a brake. After the separator is discharged the motor DM is de-energized, the clutch is disengaged and the brake applied and released to complete the operating cycle of the separator. The switches in the control circuit Fig. 16 (not shown), of the motors are automatically operated after the charging of the separator by means of a circuit Fig. 17 (not shown), which also controls the brake and the mechanism of the separator.
