Abstract: 996, 572. Thermometers. E. KIEBACK, and P. PETER. March 14, 1962 [March 22, 1961], No. 9802/62. Headings G1D and G1N. To compensate for the cooling effect on a building of winds at different angles, a thermometer used in controlling a heating system is placed in a casing 2<SP>1</SP>, Fig. 2, placed adjacent, but spaced from, an outside wall of the building, the casing 2<SP>1</SP> having an air inlet 15 facing towards a wind blowing perpendicularly at the wall of the building and downwardly or upwardly directed air outlets 11<SP>1</SP> having horizontal outlet edges. The thermometer may be in the form of a metal or plastic sleeve 5 with a resistance winding 6, a heating winding 7 being within the sleeve 5 to provide a manually controlled modifying influence. By arranging one outlet 11<SP>1</SP> facing the building and two more outlets 11<SP>1</SP> at 120‹ thereto, the cooling effect of the wind on the resistance thermometer varies according to the direction of the wind in an amount corresponding to the effect on the building. In a modification there is only one outlet, facing the building, and the inlet is a passage in the lower part of the casing which is heart-shaped in crosssection, Fig. 1a, so that an oblique wind is partly diverted by rib 13 back to the inlet 8. In a further form the inlet is a vertical slit in the casing and the resistance thermometer is enclosed in an open ended tube which extends through the bottom of the casing to form the outlet. About a third of the casing on the side facing the building may be painted black and the rest white or reflecting so that warmth radiated from the wall of the building will be allowed for but direct solar radiation will have little effect.

Title: Electronic switching telephone system
IPC: H03K19/177
Filed: 1961-03-17
Abstract: 953,895. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. March 17, 1961 [March 23, 1960], No. 9850/61. Heading H4K. In a system in which connections are set up between inlets and outlets over a plurality of cascaded cross-point matrices, each inlet is associated with a time position in a repetitive cycle and connection between a marked inlet and a marked outlet is effected by extending, during the time position of the inlet, a plurality of self-seeking switching paths through the matrices towards the marked outlet, means being responsive to the completion of one path to block the other paths. As shown, a link 290 is pre-allotted by the operation of a contact 297 by earthing, via a resistance, the corresponding vertical multiple 280 of the incoming secondary matrix. When subscriber A lifts his handset he sends a preliminary tone which is detected by detector 212 whose output enables one input of " and " gate 213. These " and " gates are scanned cyclically by scanner 200, to cause an enabled gate to apply a large negative potential to the horizontal multiple 233 of the primary matrix, thus breaking down the PNPN diodes 231, 232 . . . provided these are not already engaged in a call, in which case their other poles will be connected to negative potential so that they will not break down. Assuming all paths are free the high negative potential is then applied via diodes 231, 232 . . . to the horizontal multiples of the intermediate matrices to break down the diodes therein and thence to the horizontal multiples of the incoming secondary matrices, and thus to diodes 281, 283 therein. Assuming 281 breaks down first, the full negative potential is then applied to the vertical multiple 282 and this prevents 283 from subsequently breaking down. The connection is held from earth which is applied either from the allotter or the link to a holding negative potential applied via rectifier 215. In the unselected paths condensers such as 243 charge up to cut off any diodes which have been broken down. The wanted number is now received in the register 291 and this identity is fed over 203 to the scanner 200 which thereupon emits over lead 206 a pulse in the time position of the wanted line. If the wanted line is busy pulses received from the link involved will inhibit this pulse at 248. Otherwise the pulse is extended to gates such as 223 and gated in by the scanning pulse at 224 to the primary matrix. Moreover, the pulse from 248 is passed over lead 249a to the allotter which also receives (over leads not shown) pulses from the registers in the called subscriber time position. The allotter thus identifies the link concerned and closes the corresponding contact 296 to mark the outgoing secondary matrix. The connection from called subscriber to the link is then set up in the same manner as on the calling side. Specifications 813,862 and 938,685 are referred to.

Abstract: 1459509 Electro-erosion S-A E BUTRON 6 March 1974 [6 March 1973] 9997/74 Heading B3V An electro erosion gap 13 is supplied with machining power comprising direct voltage on which are superimposed first and second trains of pulses 1, 3 having an opposite polarity and larger amplitude than the direct voltage, the second pulse train comprising pulses 1 of higher repetition rate and smaller width than the pulses 3 of the first train and being selectively superimposed on the direct voltage for variable time periods. In one embodiment, the electrodeworkpiece gap 13 is connected to a main rectifier 7 fed with power via saturable reactors 5 which are controllable by a regulator 6. Pulses 1 from a high frequency generator 8 and pulses 3 from a low frequency generator 11 are superimposed on the output of the rectifier 7 by transformers 9, 12 such that the polarities of the pulses are opposite to that of the direct current from the rectifier 7. The generators are controlled by a timer 10. A silicon controlled rectifier by-pass 14 is connected across the erosion gap and is triggered by a circuit 15 in response to pulses from the generator 11 to facilitate extinguishing of the erosion arc. The dielectric may be slightly alkaline (soapy) deionized water at a tempera. ture of 90‹ C. In another embodiment (Fig. 4, not shown) a trigger circuit (26) is actuated when a short circuit occurs which causes a silicon controlled rectifier (24) to block the supply of direct current. The by-pass (27) is triggered by one of the pulse generators (28). The electrode (33) comprises individual sections insulated from each other and each connected to each terminal of the main rectifier via a resistor (34, 35). In another embodiment (Fig. 5, not shown) power is supplied to the erosion gap (42) via a pair of transformers (36, 47) having variable output voltages, rectifiers (38, 44) and trans. formers (39, 45) connected to pulse generators (40, 43). Short circuits are blocked by a circuit (41). Suitable examples of pulse generators which may be used are described (Figs. 2 and 6, not shown).

Title: Method for bleaching fruit juices and activating the bleaching adsorption resins by organic acids being in fruit juice
Inventor: MAGYAR KAROLYNE
Filed: 1987-06-22
Abstract: Clarified and polished fruit juices are decolourised by passing them through columns of adsorbent resins. Decolourising is continued until the absorption value of the colour of the fruit juice remains within 40% of its initial level, thus satisfying predetermd. requirements. When this value is exceeded, the flow of fruit juices is stopped and having displaced juices remaining in the column by water, the column is regenerated. For this purpose the column is eluted by an alkaline soln. followed by a water rinse, until the effluent pH falls below 11. Organic acids present in the fruit juices are used for reactivation of the resin. For this, fruit juices of pH below 4 are passed through the column until the pH of the effluent falls below 5, and the initial absorption value is re-established. - Decolourising and regeneration is subsequently repeated when reqd. Decolourised fruit juice batches are pref. collected in the same holding vessel.
