Abstract: So that one of a group of flyers can be stopped e.g. for piecing-up, a hand-brake is slidably mounted on a rail running along a length of the frame and can be turned by a handle into position for use with any one of the group.  A bracket 6, Fig. 1, not shown is mounted to slide on, but not to turn about, a rail 3 running along a group of flyers.  The brake comprises shoes 12, 13 the former mounted on a bracket 15 which can be rotated clockwise by a handle 17 about a pivot 16 against the action of a spring 20, which tends to maintain the bracket clear of the wharves 1, and the latter urged to turn towards the former by a spring 27, but normally prevented from so turning by engagement at 19 with bracket 15.  The brake is moved along the rail opposite the wharve 1 it is desired to brake, and handle 17 is rotated clockwise to rotate the bracket 15 so that the shoe 12 is brought against the wharve, and the shoe 13 is released, the shoes being forced apart to slip over the wharve, the springs then causing the shoes to grip.  If the wharve stops in an inconvenient position, it can be allowed to rotate slightly by tapping the handle 17 or operating a handle 26.  A number of brakes can be mounted on a rail running the length of the machine.  A catch may be provided to keep the bracket 15 clear of the wharves.

Abstract: 630,153. Coffee. APPAREILS & EVAPORATEURS KESTNER. Jan. 24, 1947, No. 2335. Convention date, Dec. 23, 1946. [A Specification was laid open to inspection under Sect. 91 of the Acts July 24, 1947.] [Class 129] Powdered green unroasted coffee is treated with a solvent to extract fatty aromatic products and is then further extracted with water or vapour. After removal of the solvent, the two extracts are combined and evaporated to dryness. Finally, the product is heated to develop the flavour. The extraction with solvent takes place in an extractor 1, the laden solvent being collected in a vessel 2 and passed to a distilling column 4, where the solvent is removed. The solvent passes by way of a condenser 5 and a retort 6 to a storage vessel 7, ready for further use. The green coffee passes to an infuser 9, where it is infused with water or vapour. Moisture is removed from the coffee in a drier 10 and added to the infusion juices in a storage vessel 11. The juices, after passing through a reheater 13, are concentrated in a concentrator 13a. The latter is connected to a distillation column 14 for the recovery of residual solvent. The two sets of extracts are combined in a vessel 15 and spray-dried in a drying chamber 17. The resultant powder is passed to an autoclave 23, where it is heated with or without the presence of water vapour to develop the flavour.

Title: Improvements in centrifugal liquid purifiers
IPC: B04B15/08
Filed: 1925-01-27
Abstract: 252,421. De Laval Chadburn Co., Ltd., and Chadburn, W. R. Jan. 27. 1925. Density separators; discharging; preventing atmospheric reaction. -An inert, or otherwise desirable gas, is introduced through the stationary casing of a centrifugal purifier for liquids, into the chambers in which the liquids are sprayed from the bowl, so that the gas can operate by direct contact with the liquids. In the arrangement shown in Fig. 1, the bowl 1 discharges freely one liquid which is collected in the casing 3 and passes through the spout 4 to the collecting-tank 9. The desirable gas is supplied from the reservoir 7 through the pipe 6 and regulating valve 8 so that the chamber inside the casing 3 is kept at a pressure above atmospheric pressure. As it is sprayed through the chamber the liquid absorbs gas and passes on to the tank 9 where more gas may be absorbed from that carried over by the liquid as the separation in the tank often takes a considerable time. Gas absorbed by the liquid before it is supplied to the centrifugal machine will be replaced by the desirable gas during the action. In a modified form of apparatus, economy of the desirable gas, such as carbonic acid gas, oxygen, or nitrogen is effected by circulating arrangements. A vacuum pump 12, Fig. 2, is used to withdraw air from the system at starting; its connection to the system includes the valve 15 which shuts automatically when a predetermined difference of pressure exists between inside and outside the system. The desirable gas is then supplied. The outlet 4 from the centrifugal machine is connected by a pipe to the enclosed tank 10 and this pipe not only conveys liquid and gas to the tank, but conveys separated gas from the tank back to the casing 3. If desired, another pipe 16 may be used to convey the gas back from the tank. As soon as the liquid in the tank 10 reaches a certain height a flow commences in the pipe 11. As the system works under a pressure greater than that of the atmosphere, packing joints and liquid seals are used to prevent leakage. In another modification, the separator delivers two liquids to chambers in its casing which are connected to two separate tanks. To equalize the gas pressures these tanks are connected by a pipe, and the pipe may include some moistureabsorbing arrangement. The collecting-tanks used in these systems may contain a number of thin partitions 22, Fig. 4, inclined to the vertical; the liquid passes through in thin layers and the escape and return of the desirable gas is facilitated. With the apparatus described, oxygen in oils may be replaced by inert gases such as carbonic acid gas or nitrogen, or oxygen in boiler-feed water may be replaced by inert gas to precent corrosion of the boiler.
