Title: Improvements in refrigerating systems for refrigerating chambers
IPC: F25D11/00
Filed: 1923-05-22
Abstract: 197,963. Automatic Refrigerating Co., (Assignees of Lundgaard, I.). May 22, 1922, [Convention date]. Refrigerators, domestic and like; refrigerating, cold-air machines for; ice-making, can or mould apparatus for.-A refrigerator is fitted with a cold-air refrigerating machine which may be of the type described in Specification 157,261, the air of the storage chamber 2 flowing by natural circulation over an interchanger 8 at the expansion end of a combined compression and expansion cylinder of the machine. The heat of compression is absorbed by atmospheric air circulated by a fan 40 around an interchanger 47 at the hot end of the cylinder. The machine and fan are driven by an electric motor 32, the circuit of which is controlled by a ther. mostat 20 in the storage chamber. The walls of the chamber 2 and of partitions 12, 13, 14, 15 are heat-insulated by material such as pressed cork. The heat interchanger 8 comprises leaves or fins 10 over which the air of the chamber flows. Moisture deposited and frozen on these fins during active periods is thawed during idle periods and passes over a tray 11 to a trapped pipe 64 leading to a reservoir 63. This reservoir is fitted with a wick 65 exposed to the current of atmospheric air exhausted from the interchanger 47 so that the moisture is absorbed by the air and discharged therewith. The air of the storage chamber flows through an opening 17 above the partition 15 and down a flue 16 between the partitions 12, 15. A part of the cooled air may be diverted by a damper 27 through a heat-insulated box 22 containing moulds 21 for water to be frozen. The electric motor 32 is supported on a rod 33 mounted in bearings 37, in such a manner that its weight tends to tighten the belt 31, particularly at starting. The air for cooling is drawn in through a grating 42, Fig. 2, and dust bag 43, which are detachable from the exterior for cleaning, and is delivered to a passage in the interchanger 47. It passes over fins 48 and escapes by openings 50 around the base of the cylinder or cylinders and through a passage 51 adjacent a sheet-metal wall of the machine compartment. The fan pulley 41 serves as a tensioning pulley for the belt.

Patent GB-855399-A (GB)
Title: Code converter
IPC: G11B5/004
Filed: 1959-04-24
Abstract: 855,399. Digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 24, 1959 [April 25, 1958], No. 13993/59. Class 106 (1). Signals representing decimal digits are converted from a parallel to a serial-parallel form in order to increase the bit density of a storage medium such as a magnetic drum without altering its speed or the frequency of associated circuits. Decimal digits are represented in the 5-bit code shown in Fig. 6 by the state of five input leads and are stored on three tracks of a drum in the form shown in Fig. 7. In Fig. 1 is shown only apparatus associated with the " 6 " and " 0 " input lines, signals on which are recorded in the top and bottom halves respectively of addresses in the left-hand track of the three. With each address are associated timing pulses A to D. A signal on input line 6 is gated by a D-pulse to an inverter 6, and to an OR circuit 5 and a write latch 9 which is switched on for four microseconds. The output of latch 9 s fed to a coil 15 of a read/write head and the circuit is completed by address selector 20. Should line "0" be marked with line " 6 " the signal on line "0" is gated by the D-pulse to a delay latch 23 which is on for about six microseconds. The latch 23 output is then gated by a B-pulse to OR circuit 5 to maintain the write latch 9 on for a further four microseconds resulting in the writing in of an O-bit. Should there be no signal on line " 6 " inverter 6 gives a positive output which is applied through OR circuit 28 to turn it off. This produces an output on line 31 which since the preferred method of recording is NRZ is applied through coil 16 to saturate the medium in the opposite direction. Similarly should there be no signal on line " 0 " the output of inverter 6 is effective to turn off the latch after four microseconds. A signal read by the read/write head is passed through amplifying and shaping means 600, 620, 650 to a read latch 41 to turn it on. If the signal is a 6-bit the output of latch 41 is gated by a C-pulse to delay latch 51. If an O-bit is then read latch 41 is maintained on and the output is applied to gate 45 through which it is gated to O-bit output circuit 80 by an A-pulse which also gates the output of delay latch 51 to 6-bit output 70. If no O-bit is read the output of latch 44 after passing through delay 130 turns the latch off. The circuits and components are described in more detail in the Specification with respect to Figs. 4a to 4f (not shown).
