Title: Code Communication System
Inventor: COLEY NELSON BRADFORD
IPC: H03M13/51
Filed: 1969-02-17
Abstract: 1,188,493. Electric selective signalling. GENERAL SIGNAL CORP. 17 Feb., 1969 [21 Feb., 1968], No. 8399/69. Heading G4H. A signalling system comprises transmitting and receiving apparatus at each of first and second stations for two-way communication over a channel 10, means 13 at the first station for encoding in binary form a plurality of words for transmission during a cycle of operation, the words always having the same number of "1's" and "0's", storage means 14-16 at the first station for storing a number of coded words and having an output for each bit, an answerback store 33 at the first station for storing coded words received over the channel having an output for each stored bit, the output being of opposite polarity to that of stores 14- 16, means for connecting the corresponding outputs of the two stores together and for providing an output when the signals are not opposite. The operator uses key-board 12 to send first a first 5-bit word defining the mode of operation to be followed. He then sends three more words, each of five bits and defining a number digit which designates a particular remote apparatus to be controlled. The keyboard signals pass in succession to a 5-bit coder 13 and the digits to be transmitted are stored in registers 14-16, under the control of scanner 19. When the three digits are entered a signal on lead 17 causes circuit 18 to restart scanner 19 which then makes a transmission cycle. The digits are sent by signals on lines 20, 22, 23 in succession to the serializer 21 for application to the channel 10, "1" bits being represented by a negative potential. At the end of its operation scanner 19 sends a signal to momentarily pick relay CS which causes lamp CSK to flash, indicating that the transmission is complete. The selected field station sends an answerback signal, the first coded word of which defines it as an answerback signal and the next three are corresponding number digits. The first word causes mode selector 27 to pick relay CMP which self-holds and applies a signal to start circuit 18 to start the scanner 19 again. The digit words are received in succession and applied in turn to a two-out-of-five check circuit 31. If valid the words pass to store 33 where they are compared with the words sent, read out of stores 14-16 in turn by scanner 19. The "1" bits from the stores 14-16 are represented by negative voltages, those from store 33 by positive voltages, and for perfect agreement all voltages should cancel. If they do not, relay CR picks and resets scanner 19. If they do cancel the scanner 19 goes on to its final stage and energizes check relay CS to light lamp CSK. The operator then transmits the necessary control signals.

Title: Improvements in or relating to vacuum impregnation apparatus, and methods of operating such apparatus
IPC: B01J3/00
Filed: 1951-04-11
Abstract: 713,532. Vacuum impregnation. VOGT, A. April 11, 1951 [April 11, 1950], No. 8409/51. Class 140. In a method, of operating vacuum impregnation apparatus in which the impregnation medium is spread out on the outer surface of an impregna-. tion chamber in a layer thin compared with the width of the chamber, and is held. in this way in a reserve chamber, the medium, melted if necessary, is then brought into the chamber under the action of a vacuum produced therein and any excess medium unused in the impregnation is then conveyed back to the reserve chamber by a..vacuum applied thereto. As shown in Fig. 1, the apparatus comprises an impregnation tank 10 within an outer reservoir tank :11, the whole being closed in a vacuum-tight manner and each being connected to a vacuum pump 27 and each having a conduit (23; 20 respectively) leading from the bottom to valves 21, 24. Heating elements 14, 15.with heat insulator 16 between are provided, respectively . surrounding the inner tank 10 and near the partition wall 12 forming the inner limit of a reservoir chamber 13 bounded externally by the tank wall 11. On placing the inner tank 10 serving as impregnation chamber 10a under vacuum and unlocking valve 21 melted impregnation medium in the chamber 13 moves through conduit 20 and discharges into the impregnation chamber 10a, the valve 21 opening to permit such flow. If the valve 21 was unlocked and the chamber 13 was under vacuum, a flow of impregnation medium would not be permitted by valve 21 in the reverse direction since the higher pressure in chamber 10a would maintain the valve closed. If the reservoir chamber 13 is placed under vacuum and the valve 24 is unlocked, impregnating medium flows through the conduit 23 back again into the reserve chamber 13, the valve being such that it may only open when the pressure conditions are such as to move the medium back to the chamber 13. In a modification as shown in Fig. 3 the connecting conduit 30 is disposed at the bottom of the inner tank 10 so that it only has the form of a conduit leading from the chamber 13 to the chamber 10a.The valve plate 31 operates together with the upper end of the conduit 30 located in the tank 10 so that the conduit may be closed. A bolt 32 connected to the plate 31 is mounted for - longitudinal displacement in a bushing 33. located at the bottom of the outer tank 12 and is pivotally connected to a lever 34. A compression spring 35 holds the valve 31, 32 closed at all times unless the lever 34 is operated normally by depressing a foot pedal 36 on the lever 34. According to a modification (not shown) an additional chamber surrounds the reserve chamber (having if necessary heating means between them), and may contain purification devices, e.g. filters for the medium, wherein the movement of the latter through the purification chamber may take place according to changes of the medium in the impregnating chamber which preferably is connected by tubular conduits to the reserve chamber.

Abstract: 256,889. Seymour, J. M. March 29, 1926. Liquids, treating with gases. - Condenser-water or other liquid to be cooled is distributed in fine streams from the top of a tower 2 to which tangential streams of cooling-air are supplied or admitted at the base, so that a whirling or gyrating motion thereby given to the air causes the unsaturated air to move towards the side walls of the tower and the saturated air to flow directly upwards to a central outlet 4. Where forced air circulation is used, motordriven fans 16 may be arranged in the air inlet pipes 15, and no chimney or flue is necessary; where natural draught is used, a flue 3 may be supported by pillars 5 leaving an unobstructed central space in the tower. The water is preferably supplied to a spiral trough 8 having radial slits or other perforations 11 in the bottom. The ends of the trough abut against a partition 9 having a valve 14 permitting flow of excess water into the tower, and preventing outflow of air. A partial cooling effect takes place during the passage of the liquid along the trough when the latter is open to the air, as is preferable. With natural draught, dampers may be fitted in the air inlet pipes 15 to regulate the flow. A part of the liquid flows as a film down the sides of the tower, where it is cooled by the dry air thrown towards the sides.
