A system for cooling and dehumidifying the air in an enclosure comprises two heat exchangers 3, 4 through which outside air will be forced by a fan 40 and two heat exchangers 7, 8 through which room air is drawn by a fan 27, this air entering via apertures 26 and returning to the room via outlets 28. A changeover valve 10, Fig. 2, enables fluid in a refrigerating system which includes a compressor 1 to flow through the exchangers 3, 4, 7 and 8, in that order, the exchangers 3, 4 acting as condensers and exchangers 7, 8 acting as evaporators whereby the air is both cooled and dehumidified. On changeover of the valve 10, the refrigerant flows from the compressor 1 through exchanger 3 and valve 10 to exchanger 7 and through a capillary tube 9 and the exchanger 8 to return to the compressor. Under these conditions, which are operative when the room air is initially at an acceptable temperature but the humidity is too high, moisture will be removed by the exchanger 8 which cools the room air and exchanger 7 will re-heat the air back to the original acceptable temperature. The refrigeration circuit also includes another capillary tube 6 and a check valve 5 through which the fluid passes when the condition shown in Fig. 2 is operative.

An air pump comprises a housing 1, 2 defining a chamber 5 receiving air through an inlet 25 and an electrically heated resistor wire 17 intermittently energized through a temperature responsive switch 11 to cause the pressure of the air within the chamber 5 to increase and thus flow through an outlet valve 40. The outlet valve 40 comprises a valve member 38 loaded by a spring 37 co-operating with a seat 36 formed in a metal insert 27 in the housing part 2 of insulating material. The temperature responsive switch 11 may be in the form of a U-shaped bi-metallic strip 7 or a cantilever operated by the expansion and contraction of the heated resistor wire, Fig. 5 (not shown). Different ways of controlling the inlet 25 are described. As shown, control is by a valve 30 having a valve member urged against a seat 27 by a spring bearing against an abutment movable with the bi-metallic strip 7. When the strip reaches a predetermined temperature it is caused to snap upwardly by a spring 21 and thus opens the valve 30 to admit a fresh change of air to the chamber 5. Alternatively, Fig. 9, (not shown) a capilliary, or a porous plug (170) of compressed, sintered metal powder controls flow through the inlet 25. In Fig. 7 and 9 (not shown) the inlet and/or the outlet valve are in the form of differntial pressure operated valves including a metal diaphragm.

Abstract: 1,164,490. Digital transmission systems. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 13 Dec., 1966 [15 Dec., 1965], No. 55893/66. Heading H4P. A cipher key generator comprises a source 1 of a sequence of random signals and a counter 5 for completing an alphabet if all letters of the alphabet have not been generated by source 1 when the source has emitted a preset number N of signals. Source 1 emits a parallel-bit signal representing a letter for each pulse from a clock 2. The signal passes to cipher key output K and also to unit 7 which triggers a store 8 corresponding to the signal. OR gate 10 gives a pulse D when an untriggered store is triggered. Counter 4 counts N clock pulses and then reverses switch 3 and enables gate 11. If not all the stores 8 are triggered, counter 5 provides parallel-bit signals which pass to output K and also trigger the stores 8. When all stores are triggered gate 9 gives a pulse C and, via gate 11, stops clock 2. Thus, in this one cycle of operation output K contains all letters at least once. Ciphering.-Various arrangements are described, in each of which upon coincidence of a clear signal to be ciphered and a cipher key signal another key signal is transmitted to represent the clear signal. This other key signal may be, for example, the signal prior to that which caused coincidence, Fig. 4 (not shown). In such a case if the signal causing coincidence is the first signal in the key sequence then the clear letter is sent unciphered. In a further embodiment, Fig. 7 (not shown), the clear signals are compared (300) only with key signals occurring for the first time, i.e. those causing a pulse D. Each such key signal is passed to one of a number of stores (43), selected by a switch (42) controlled by the D pulses. A further switch (45) connects the system output (46) to the stores in an order controlled by the pulses D. When coincidence of the clear and cipher signals occurs, the further switch stops scanning and, when a C pulse arrives, the cipher signal in the selected store is transmitted to represent the clear signal. Deciphering.-The deciphering processes are the reverse of the ciphering processes.

A micro instruction is read from ROM 15 and one of registers 13 which acts as an address is incremented. Execution of micro instructions is controlled by a status register 23 the contents of which are controlled by a field F of 4 fields of the micro-instruction. Read out occurs in a single machine cycle of a timing unit 19 and is identified by a flip-flop of register 23. One or more cycles is required for execution during which the micro instruction remains in register 17, while the contents of register 23 change through four executive states each of which defines the next according to the micro instruction. The logic unit 21 in accordance with the contents, of registers 17, 23 generates control signals. The instructions contain addresses of operands in the core store 11 and register 13 hold data to be operated on, e.g. by arithmetic unit 25 and can act as addressers for the ROM 15 or core store 11 and hold data to be exchanged with the store, a console or a peripheral unit. The addresses may be modified by a register 63. The logic unit controls the flow of data via various AND gates, shown as blocks holding 3 sets of data, which can transfer a given number of bits in various positions, e.g. 0700-0700 transfers 8 bits in parallel and 0300-0704 transfers 4 bits shifted left 4 positions.
