Abstract: 783,261. Current supply for resistance heaters. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. May 24, 1955 [Feb. 25, 1954], No. 5578/54. Class 39(3) [Also in Group XXXV] In electrically heated apparatus having a heat capacity in such relation to the heating power that the normal operating temperature is attained only after a considerable interval after switching on, e.g. a hotplate, contacts 7, 8 of a thermal time delay means are connected with the heater sections 2, 3 so that when the relay is cold the supply terminals L, N are connected for rapid heating of the apparatus, and when the relay is hot the sections 2, 3 are connected in series for normal operation, the relay means having a heater 10 which is connected with the terminals L, N in circuit with the contacts of a main switch 4 or regulator for the apparatus so that the heater 10 is energized at all times when the apparatus is switched on and to change the heater sections from the first connections to the second connections after a time delay, and thereafter to maintain the second connections until the main switch or regulator is turned off. The thermal time delay means comprises a bimetallic strip 9 carrying a contact 7 and a heater 10, and is so designed or has thermal insulation so arranged that the time for the delay means to cool down to the temperature at which the second connections are made (for normal operation) corresponds to the time taken for the heating apparatus to cool down to the temperature at which the second connections can be made. The contacts 7, 8 of the delay means are arranged so that when the delay means is cold, one section 2 of the heater is short-circuited and another section 3 is connected across the terminals L, N. Alternatively in Fig. 3 (not shown) the sections 2, 3 are connected first in parallel and then the thermal relay after delay switches to series connection. A variable heat switch or energy regulator 20 may be connected in circuit with the heating apparatus and has contacts 21, 22 which are open in the "off' position of the regulator but when closed connect the heater 10 of the delay means to the supply conductors L, N. The energy regulator may be a "Simmerstat" (Registered Trade Mark) made according to Specifications 517,538 and 587,947 [both in Group XXXVII]. The auxiliary contacts 21, 22 may be employed with a variable heat switch controlling the connectors of a plurality of hot-plate heater sections. Specification 783,262 also is referred to.

Abstract: 1,260,826. Separation of fructose from glucose. R. TATUKI, and T. KUBO. 6 Feb., 1970 [17 Feb., 1969; 26 Aug., 1969; 20 Dec., 1969], No. 5849/70. Heading C2C. Fructose is separated from a neutral or acidic aqueous solution containing fructose and glucose having a Brix value of less than 77 by treating the solution with calcium chloride such that the solution contains above 15% by weight of calcium chloride based on the total amount of sugars, heating the solution under reduced pressure to concentrate the solution to a Brix value of at least 77, slowly cooling the concentrated solution while slowly stirring the same whereby a fructose-calcium chloride double salt is formed, and recovering fructose from said double salt. The recovery of the fructose may be achieved by electrodializing an aqueous solution of the double salt in a device having an ion exchange membrane for electrodialysis using the initial sugar solution containing fructose and glucose as diffusate. The calcium chloride may be formed in situ in the above process.

Filed: 1966-02-14
Abstract: In a process for making vinegar, medicinal plants (marjoram, thyme, gentian, juniper, liquorice, achilla, chamomile, anis, absinthe or fennel) are extracted under a vacuum sufficient to cause the plants to explode and the oils and mineral salts thereby released from the plants are collected to form a first extract, the dry extraction residue of the plants is extracted with hot water to give a second extract rich in acids, the two extracts are mixed, liquid honey and albumin-free whey are added, this mixture is in turn mixed with cider vinegar, the resulting final mixture is subjected to at least one slow fermentation and the vinegar so formed is recovered. If desired, all the operations mentioned may be carried out in the cold.  A second fermentation partially initiated by the hydromel of the honey may be carried out in a closed vat in the absence of air and without agitation, decantation being effected during the fermentation to obtain a clear vinegar.

Patent GB-1386362-A (GB)
Title: Electronic flash apparatus control
IPC: G03B7/16
Filed: 1972-02-11
Abstract: 1386362 Photographic exposure control  ASAHI KOGAKU KOGYO KK 11 Feb 1972 [12 Feb 1971] 6596/72 Headings G2A and G2X The correct electronic flash exposure for a camera is computed by converting electrically values corresponding to the distance of the object being photographed, the aperture setting and the sensitivity of the light-sensitive material into logarithmic values to the base 2 and computing a guide number therefrom, the computation being in accordance with the APEX-represented values. The light output from the flash device may be varied by use of a shunt quenching system, a series controlled SCR, by mechanically covering the discharge tube or by varying the voltage or capacity of the charge storage capacitor. The computed guide number may be indicated by a linear meter M, Fig. 2, the reading being manually transferred to the flash device, or the computed value may be produced in a circuit, Fig. 4, which also controls the shutter exposure time of a camera. In the meter arrangement of Fig. 2, the object distance is set by adjustment of resistor RD, and logarithmic compression diode D 1  produces a voltage V 1  which corresponds to the logarithm of the object distance. The voltage is fed to a variable gain amplifier Q 1  and a buffer circuit Q 2  to obtain a voltage V 2  proportional to the logarithm of the set distance. A further voltage V3 is obtained proportional to the logarithm of the diaphragm aperture and film speed sensitivity. The difference between these voltages, Va is connected to the meter M whose scale is linearly calibrated in terms of the flash guide E v . Variable resistors VR 1  and VR 2  are provided to provide γ compensation for the respective circuits. In Fig. 4, switch SW 2  is set to contact a when ambient light is used to control the exposure time and thus flash is not required, and set to contact b when automatic flash control according to object distance, set by RD, is required. In the latter event, the voltage across the meter terminals d, e is applied to transistors Q 6 , Q 7  to logarithmically expand the APEX value G v  of the flash guide number G, so that the number itself is used to control the voltage to which the storage capacitor C 2  is charged. Transistors Q 8 , Q 9  operate as a comparison amplifier so that transistor Q 10  is cut-off when the voltage across C 2  reaches the value determined by the calculated guide number G. When flash exposure is not required, the voltage T v  across terminals d, e of the meter M corresponds to the APEX value of the required exposure time, and this is used to control the charging of timing capacitor C 4  during an exposure, which exposure is terminated by de-energizing electromagnet MAG.
