Title: Improved combined mixing and homogenising apparatus
IPC: B01F27/91
Filed: 1965-05-18
Abstract: 1,100,782. Homogenising apparatus; mixing apparatus. A. BRATLAND. 18 May, 1965 [21 May, 1964; 9 March, 1965], No., 21007/65. Headings BIC and BIV. To prevent leakage between a stationary part 142 and a rotatable part 141 of a combined motor driven mixing and homogenising arrangement which extends through the base of a container, parallel sealing surfaces 155 and 161 are provided on the parts so that while at rest the parts are sealed but on rotation the rotatable part is axially displaceable a predetermined amount to break the seal. Bearings 157 and 158 and sealing ring 154 ensure tight sealing between the shafts 143 and 139 of the parts. Through-passages 145 in the stationary part are aligned with passages 144 in the other part when axially displaced, and vanes 167 combined with the centrifugal force subjects the material to rapid movement through the passages. The axial displacement is brought about either by the force of reaction on the rotatable part or by the driving motor causing axial displacement of the rotatable part in opposite directions on starting up and stopping the motor. The shaft 143 is secured to the container 110 (Fig. 5, not shown) which is surrounded by an outer container 111, the space therebetween containing heating elements 132 and conduits 127, 129 for circulating cold water so that three treatment stages, namely a heating stage (pasturisation), a homogenising stage, and a cooling stage may be carried out in the same inner container, as in the production of milk products from dried milk. The through passages may extend longitudinally (Fig. 3, not shown).

Title: Improvements in cooling bed
IPC: B21B43/00
Filed: 1947-08-01
Abstract: 630,759. Rolling. BIRDSBORO STEEL FOUNDRY & MACHINE CO. Aug. 1, 1947, No. 21041. Convention date, April 6, 1942. [Class 83 (iv)] A cooling-bed is provided with mechanism for placing bars vertically on edge to form a pack and mechanism, to laterally support bars thus placed against over-turning, which includes travelling abutments initially engaging the side of the leading bar of the pack, and moving at an angle to the plane of the pack-annealing section so as to finally engage the upper edge of the bar. A bar 1 is received from the rolling mill by conveyer rollers 2, lifted clear of the rollers on aprons 3 by operation of cranks 3b and kicked off to slide down the section 4 of the bed by side-plates 5 adjustably-mounted and rotatable about pins 5a by means of turnbuckle links 5b and cranks spaced along a shaft 5c. The bar is lifted on to the pack-annealing section 7 by packing arms 11 mounted on a shaft 10, the upper edge of the bar displacing and passing beyond the projecting ends of pivoted latch-members 31 which fall back into their original positions determined by stops 33. Shaft 10 is then operated to return the arms 11 to their lower position. The building up of the pack causes the counterweighted abutments 34 to retreat. The abutments travel in inclined tracks 35 on arms 12 so that the depth of engagement between the pack and the abutments is gradually reduced until with the original pack completed, the addition of another bar causes the first bar to fall down the discharge section 8 to the final cooling section 9. When rolling is completed the residual pack remaining on the section 7 is discharged, after annealing by slowly cooling, by tilting the bed by rotation of shaft 7a connected to the supporting beam 6a by a turnbuckle link 8a. Each arm 12 is pivoted at 13 to a slide 14 guided for vertical movement and connected by a turnbuckle link 22 to a bellcrank 19 rotated by operation of a thrust-rod 24. An extension 25 of each arm 12 is pivotally connected to a slotted link 28, so that the arms 12 may be adjusted vertically without angular change of position. When the pin 26 engages the upper end of the slot 28a, further vertical movement of the slide 14 causes the arms to tilt, to restore to starting position the abutments 34 or make the bed accessible. In a modification, Fig. 9, the abutment tracks 35 are horizontal and the packing section 7 is tilted on shaft 10 to cause the abutments 34 to recede from engagement with the pack, and the faces 41 of the packing arms 11 are shaped to deliver the bars at desired inclinations. The bars of the residual pack can then be disposed of without delay by separating them manually and causing them to slide down the discharge section 8.

Filed: 1955-07-21
Abstract: <PICT:0779423/IV(b)/1> <PICT:0779423/IV(b)/2> <PICT:0779423/IV(b)/3> An impregnated fabric F fed from a supply trough 10 is led into a known pleating machine 13 and is fed from there without tension into a curing oven A where heated air or other gas is supplied from trunking 25 and manifolds 28, 29 to perforated tubes 31 and 32.  The gas passes from the tubes 31 through the pleated fabric PF being carried along on a conveyer belt 19, 19R passing around an idle drum 2- and a driven drum 21, and is exhausted via downcomers 33, 33a for reheating and re-circulation, Fig. 6, not shown.  The treated fabric is then batched on a roll 37 driven by contact with the conveyer, and a web of tissue paper 41 supplied from a roll 40 is interleaved between the fabric convolutions. The fabric is fed smoothly to the pleating machine by taking it from a roll 43, Fig. 5, and feeding it over a driven feed roll 46 into a trough 10, in which trough is pivotally mounted a trigger plate 47 controlling an electric motor 49 through a rheostat or relay 48.  If tension increases in the fabric then the roller 11 is lifted, thus permitting the trigger 47 to rise and adjust the rheostat to increase the speed of the motor 49 and feed more fabric to the trough, whereupon the weight responsive trigger 47 drops and reduces the motor-speed.

Title: Improvements in and relating to organs and like keyboard sound reproducing apparatus
IPC: G10H3/06
Filed: 1943-12-20
Abstract: 572,459. Electrical musical instruments. WALMSLEY, R. A. Dec. 20, 1943, No. 21328. [Classes 40 (ii) and 88 (ii)] Relates to sound - reproducing apparatus, such as organs and like musical instruments of the kind comprising a plurality of endless photographic sound records with associated photo-electric pick-up devices, and a plurality of keys for bringing the required records into use. According to the invention each key controls a connection between a common amplifier and the pick-up device associated with the particular record to be repro - duced when that key is operated, and each key controls the lamp upon which its record depends for its illumination so that current to the lamp is switched off or reduced except when the light thereof is needed for reproduction of a sound record illuminated thereby. In the construction shown in Fig. 1 record bands 1 pass over driving sprockets 2 on shai'ts 3, and around pulleys 4 supported by arms 7 extending from fixed rods 8. Brackets 9 on rods 8 carry light sources 12 and optical telescopes 11 adapted to project light beams through the films on to photo-electric cells. Each band has four sound tracks and each bracket carries four telescopes arranged in pairs with one lamp 12 between each pair. The two telescopes and cells corresponding to two sound tracks on one run of a band 1 are staggered with respect to those of an adjacent run. As shown in Fig. 4, when a key such as 17a is depressed a coil 19a is energized to move an armature 20a to a position where it closes two pairs of contacts 21a, 22a and 26, 27. Closing of the contacts 21a, 22a short circuits a resistance 23a and causes the corresponding lamp 12a, which due to the resistance is normally consuming only half its normal consumption, to light up fully. This illuminates two sound tracks, one on each of the films 1, 1a. Closing of contacts 26, 27 connects the secondary 24 of a transformer 25 (to which is connected cell 13a corresponding to key 17a) to the primary of a transformer 28 which is connected to a prestage amplifier, the latter in turn being connected to the main amplifier for the loudspeaker. Thus, although key 17a causes the illumination of two tracks it connects only one transformer to the amplifier and only one note is therefore played.
