IPC: A23G3/20
Filed: 1928-04-30
Abstract: 289,791. Kremmling, O. April 30, 1927, [Convention date]. Coating bakers' goods.-In tbe filling of open fragile pastries, such as tarts, waffles, &c., the filling-material is placed upon the pastries which are then carried between side guides and beneath a yielding wiper or scraper which presses the filling into the hollows, smooths the surface and assists in returning excess filling to the main container. As shown in Fig. 1, the pastries 4 are carried on a conveyer 3 between side guides 16, one of which is laterally adjustable to vary the working width of the machine. The filling is discharged from the container 1 by a roller 2 and the quantity thus applied to the pastry is regulated by a sliding gate 18 which can be fully opened for removal of obstructions by a lever 20. A stop 19 determines the working position of the gate 18. The filling is scraped from the roller 2 on to the pastries by a scraper 6, and is pressed into the hollows, and smoothed by a wiper 8 pivoted, by means of slotted eyes which allow vertical displacements, to the guides 16, the wiper being made in two parts so that it is adjustable to conform with the adjustable working width of the machine. The wiper may be composed wholly or partly of rubber, and the scraping pressure may be applied by a lever 11 and adjustable weight 10, or by springs. Alternatively, the wiper 8 may be fixed and the conveyer 3 supported from below by a resiliently mounted roller. The wiper 8 may have its lower edge serrated so that the projecting parts thereof sweep into the hollows of the pastry and remove some of the filling. Excess filling builds up at the back of the wiper 8 and is returned by the roller 2 to the hopper 1. a rake 17 removing pieces of broken pastry from the filling. When it is desired to apply a coating over the tops of the pastries, shoes or skids 12, adjustable on the wiper 8 by screws, bear on the tops of the pastries and maintain the lower edge of the wiper spaced from the pastries. The pastries are prevented from rising from the conveyer by similar skids 14 adjustable by screws 13. The discharge of filling from the hopper 1 is varied to suit the adjustable working width of the machine by an adjustable slide 23. A conveyer may replace the roller 2, the conveyer being arranged to engage the goods only for a short distance.

Abstract: 570,395. Distilling acids, ammonia, organic amines...GAS LIGHT & COKE CO., ADAM W. G., MURDOCH, D. G., and GOLDING, W. E. Feb. 21, 1943, No. 13267/42. [Class 32] In the removal from solutions of volatile substances present in the solution at least partly in the form of a non-volatile compound, e.g., as in the case of ammoniacal solutions where part of the ammonia is present in the form of free ammonia while part is present as fixed ammonia, e.g., non-volatile salts of ammonia which have to be converted to the free state by addition of lime before they can be distilled off in steam, the supply of such liberating agents is controlled by automatically measuring the concentration of such liberating agent in the solution and causing any departure from a predetermined concentration to control automatically the supply of liberating agent to the solution. In addition the supply of steam used in the distillation may be automatically controlled in relation to the amount of volatile substance left in the liquor after distillation as described in the Specification 570,421; reference is also made to the recovery of volatile acid amines. Free ammonia is recovered from the top part 2 of a conventional ammonia still 1 to which the ammonia liquor is fed through line 4 and, after the free ammonia has been distilled off, ispassed through line 5 to a lime mixer 6 from which the mixture is returned through line 12 to the still finally leaving through line 13. Milk of lime is supplied by a pump 8 and a pair of valves 9, 10 in parallel the valve 10 being set manually. To control the supply, part of the mixture in the line 12 is bled off through line 17 having a flow controller 18 and passes through a still 19 mechanically regulated to remove as steam a constant proportion of the water. The remainder then flows to a control unit automatically responsive to some physical property of the liquor, e.g., its hydrogen ion concentration, so as to control the valve 11. In a similar fashion the amount of steam fed to the still through line 13 provided with manually and automatically controlled valves 15, 16 is controlled by bleeding off part of the residue through constant flow controller 25, mixing with alkali and distilling in still 26, the condensate being passed to control unit 28 where again some physical property of the condensate is measured and departures therefrom caused to control the valve 16.
