Title: Process and apparatus for the manufacture of mayonnaise or mayonnaise-like products
IPC: A23L27/60
Filed: 1959-12-16
Abstract: 909,542. Mayonnaise manufacture. KNOLLENBERG, R., HAHN, C. G., and HOLDT, K. VON, [trading as SCHRODER & CO.]. Dec. 16, 1959 [Dec. 18, 1958; Feb. 19, 1959], No. 42858/59. Class 49. A process for the manufacture of mayonnaise or mayonnaise-like products comprises admixing the ingredients, e.g. oil, eggs, vinegar, hydrolysed starch, in the ratio required in the final product and conducting a first stream of the mixture continuously through a first stirring and heating mechanism to form an emulsion which then passed into a second stirring and beating mechanism into which a second stream of the initial mixture is continuously fed, the stirring and bearing being effected with air excluded. In an alternative procedure, the initial mixture is subdivided into a plurality of streams each of which is fed into a separate stirring and bearing apparatus. The quantitative ratio of the first and second streams is suitably in the range 1: 10 to 1: 1, preferably 1: 3, and after the stirring and beating the mixture is passed to an emulsifying machine. In a preferred apparatus, the first and second streams of mayonnaise mixture are pumped by proportioning pumps (not shown) to pipes 16, 17 leading to stirring and beating mechanisms 8, 9 respectively, which are enclosed within a common casing 12 of double-walled construction for cooling fluid circulation and are separated either by a partition 13 having apertures 14, or by counter-flow producing worms or propellers (not shown). The mayonnaise mixture, which is beaten by two coaxially-arranged counterrotating shafts 10 having inter-engaging beating elements 11 and driven by a motor (not shown) through infinitely variable adjusting gears, is passed for final treatment to an emulsifying machine (not shown), e.g. a colloid mill, which has an adjustable output and is surrounded by a cooling jacket. In a further form of apparatus (Fig. 4, not shown) hydrolysed starch is prepared and pumped by a proportioning pump to either the first, second or subsequent stirring and beating mechanism, or alternatively to the beaten mayonnaise before its emulsification.

Abstract: 905,220. Handling radioactive material. TESLA, NARODNI PODNIK. Dec. 23, 1959, No: 43693/59. Class 39 (4). Apparatus for the automatic conveying of radioactive samples between three stations in succession, viz. a sample input station I, a radioactivity measuring station II and an output station III comprises a base 1 having a cam surface 4 and a hole 2 receiving a motor-driven shaft 3 supporting a drive disc 5, the disc carrying a cam surface 6 and a slidable pin 8 engaging the surface 4. A plate 10, spaced from the base 1, has a slot 12 through which the pin 8 may freely pass and an aperture 13 forming a pivot for the bearing 14 of a transport disc 15. The disc 15 has three slots 17 for receiving the pin 8 and three holes 16 which may receive hoisting elements 11 slidable in the plate 10, these elements being engageable by the surface 6. A top plate 18 has holes 19 located at the stations I, II, III which are situated at equi-spaced points of a circle, the holes 16 being alignable with the holes 19. A container 20 at the station I holds the samples to be measured, these samples dropping by gravity in turn into a hole 16. A container 21 at the station III having retaining means 22 to retain a measured sample when it has been lifted thereinto by an element 11. As shown in Fig. 2, sample 24 has been measured and awaits transportation to the container 21, sample 23 has been inserted in the container 21 and sample 25 has dropped into a hole 16 for transportation to the measuring station II. Samples 26 . . . 28 await their turn in the container 20. The pin 8 is at the top of the cam surface 4 and engages the leading edge of a slot 17 so that on rotation of the shaft 3 the disc 15 is driven, the cam surface being of such length that the disc moves through an angular distance equal to that between two successive stations. On further rotation of the shaft the cam surface 6 lifts one of the elements 11 so that the sample 25 is raised towards a radioactivity detector (not shown), the surface 6 also operating a time switch causing stoppage of the rotation for a period sufficient for the measurement to be made. On further rotation of the shaft so that it completes one revolution, the other element 11 lifts the sample 24 so that it is retained in the container 21. Thus two revolutions of the shaft are required for transporting a sample between stations I and III.

Abstract: 1327266 Flash units PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 30 Sept 1970 [3 Oct 1969] 46568/70 Heading G2A [Also in Division H2] A device including a plurality of flash-bulbs connected in series is arranged so that the bulbs are fired successively by providing a shunt for each bulb except the first, each shunt being rendered inoperative by the firing of the preceding bulb. As shown in a device having two bulbs 3, 4, the shunt comprises a switching element 6 which melts when the bulb 3 is fired. A shunt 5, which closes when the bulb 3 is fired, is also provided across the bulb 3. Thus when a camera shutter is operated and current flows between terminals 1, 2, the bulb 3 will be fired first whilst, due to the element 6, insufficient current reaches the bulb 4. A second shutter operation fires the bulb 4, the closure of the shunt 5 resulting in used bulb 3 being short circuited. The row of bulbs may be extended. In another embodiment, Fig.2 (not shown), the first bulb (12) is again provided with a short-circuiting shunt (15). The next bulb (13) (and each successive bulb in an extended row) is in series with its own switch (14) closed by ignition of the preceding bulb (12), the bulb (13) and switch (14) being shunted by a resistor (16).
