Abstract: 603,742. Fastenings. ELDORADO ICE CREAM CO., Ltd., and FAVIER, C. P. Oct. 29, 1945, No. 28604. [Class 44] A fastening for thick-walled packing cases such as are used for the transport of ice-cream comprises a substantially U-shaped base 10 formed to straddle a part of the wall 16 of the case and to provide bearings for the bolt 11 which is influenced by a spring 15 to snap, when the lid 17 is closed, into a hole in the keep-plate 18 secured to the lid.

Abstract: 1317277 Feeding sheets A GRONLUNDNIELSEN 15 June 1970 [16 June 1969] 28976/70 Heading B8R A pile of sheets 2, Figs. 1 or 2, is carried on a table 1 which can be raised and lowered by an hydraulic cylinder 3, the pile being pressed upwards against a cross-bar 4. A slide 5, actuated by a pneumatic cylinder 6, has pivoted on a shaft 21, Fig. 3, an arm 20 formed with a surface 22 resting on the top sheet, a recess 28 behind it, and a pusher 25 adjustable by screws 26, 27, a spring 24 pressing the arm on to the pile. In operation, when the cylinder 6 is actuated, the pusher 25 engages an edge of the top sheet resiliently, but cannot overcome the friction between the sheet and the bar 4, the pressure against the bar is reduced by the cylinder 3, and the sheet is then pushed laterally against stops 15, with its opposite edge moving into a slit 9 between stops 7, 8, the stop 7 and the table 1 then being lowered until the edge of the sheet rests on a continuously rotating separator roller 10. When a sheet is to be fed to an associated machine, a control mechanism actuates an hydraulic cylinder 13 to lower an idler roller 11 to engage the sheet between rollers 10, 11, the sheet being fed in direction 14, either continuously or stepwise under control of the roller 11. The arm 20 is mounted on a universal joint to allow slight pivotal movement about a vertical axis. A stop 16 prevents double feed.

[Class 64(iii)] [Also in Group XXII] A heating and/or cooling chamber for heat-exchange devices, having a number of wires located within the chamber is formed by precision casting and the wires are secured to the chamber during the casting process. Fig. 1 shows a wax-casing 1 of wedgeshaped cross-section in which wires 3 are embedded transversely to the direction of flow of fluid within the chamber. To form the chamber a metal die is filled with molten wax, which when set is removed from the die. The wires being inserted in the wax model with their ends protruding, the wax is sprayed with a refractory coating such as sodium or ethyl silicate and placed in a moulding box, the normal investments used in casting, comprising a high refractory such as sellimanite being introduced. During filling the model is preferably vibrated. Upon melting of the wax the wires are left embedded in the mould the inner surface of which is the refractory coating of the wax model. The mould is then baked and afterwards filled with molten metal which upon solidification forms the casting of the chamber in which the wires are embedded. Projecting ends of the wires may be trimmed off. Fluids may be passed through the chamber or the chamber may be closed at one end and provided with an inclined baffle 5 to promote circulation. Heat transfer fins may be provided on the external wall of the chamber.

Title: A process for distilling fatty acids and other volatile substances from oils and fats, acid oils and crude fatty acids
IPC: C11B3/14
Filed: 1924-12-10
Abstract: 248,828. Armstrong, J. J. V., (Naamlooze Vennootschap A. Jurgens' Margarinefabrieken). Dec. 10, 1924. Fatty acids, obtaining and purifying; fatty oils, purifying. - In distilling fatty acids and other volatile substances from oils, fats, acid fatty oils or crude fatty acids by treatment in vacuo with steam or inert gas, the treatment is effected so that the material is heated for only a short time. The material from a tank 3 passes through a preheater 4 to a still 5 in which it flows down a filling material such as Raschig rings. The unvaporized material is continuously discharged through a cooler 7 and barometric tubes to receivers 8. The still is evacuated by an injection condenser 1 and air pump 2. Steam or inert gas is injected into the base of the still and carries the vapours through a condenser 6 maintained at about 125‹ C. to condense fatty acids, and if necessary through a second condenser to separate other volatile substances. The still is maintained at about 250‹ C. by circulating superheated steam, gases, or liquids through coils or jackets, or by electric heating devices, or by superheating the steam or gas injected into the base. Intimate contact may be obtained between the material and the steam or gas by a fine division of the material as it enters the still, or by allowing it to flow into a thin layer over a perforated plate through which the. steam or air passes. Specification 12847/93 is referred to.

Title: Improvements in or relating to apparatus for controlling flow of material
IPC: G05D11/13
Filed: 1958-09-16
Abstract: 932,552. Automatic flow control. CONSTRUCTORS JOHN BROWN Ltd., H. H. ROSENBROCK, and J. J. JISKOOT. Sept. 10, 1959 [Sept. 16, 1958], No. 29652/58. Class 38 (4). In a flow control apparatus a reference pulse generator produces a continuous succession of pulses which are compared with a succession of pulses having an instantaneous rate proportional to the flow of a material to be controlled, the factor of proportionality being controllable, and a control means responsive to the difference in the pulses to vary the rate of flow of the material so as to tend to reduce the difference. As shown, reference pulses are generated by a transistorized multivibrator 17 and fed via a buffer amplifier 29 to a frequency dividing circuit 19 comprising a four decade transistorized counter that can be set to start counting at any digit from 0 to 9999 so that an output pulse is derived at 10,000 minus the set digit. The derived pulse is fed to an input 148 of a differential counter 23. A flowmeter 15, responsive to the flow in a pipe 11, rotates a transparent disc mounted on a skew with respect to a stationary disc and a light beam through the discs to a photo-transistor is modulated by the interference patterns due to radially engraved lines on the discs. The flow pulses from the photo-transistor are fed to an input 147 of the differential counter. In the differential counter the derived and flow pulses are differentiated, the resultant negative-going pulses suppressed and the positive-going pulses applied through separate mono-stable delay circuits and a gate to an electronic register summating the flow pulses and subtracting the derived pulses; when a flow pulse coincides with a derived pulse, the gate is closed and neither pulse applied to the register. The output from the differential counter 23 is applied to a digital-analogue converter 35 having an output current varying in dependence on the number stored in the register. The analogue output current energizes an electro-pneumatic control 36, operating a valve 14, so as to maintain the flow in the pipe 11 constant. A plurality of flow control systems can be fed from the multivibrator 17, each frequency dividing circuit 19 being set for the desired flow rates. The transistorized circuits can be replaced by circuits employing cold cathode valves. The total flow is indicated on a totalizer 103 operated by the flow pulses through a frequency dividing circuit 102 set so that the totalizer reads in a desired unit.
