Abstract: 1,228,042. Heat treatment furnaces. C.I. HAYES Inc. 2 Nov., 1968, No 52036/68 Heading F4B. A heat treatment furnace comprises a heating chamber 12 with graphite heating elements 14 backed by insulating layers 16 opening into a transfer chamber 28 between oppositely disposed charging, discharging and cooling vestibules 24, 26 sealed from the atmosphere by doors 40, 42 and sealed alternately from the heating chamber by a movable plate 68. The latter engages the walls 52, 54 and 62, 64 of annular plates 50 and 60 fixed to respective vestibule walls forming with said walls chambers 56 and 66 adapted to be evacuated by a vacuum pump and then supplied with nitrogen. The heating chamber is surrounded by a fluid-cooled jacket 18 and the vestibules by water jackets 30, 32 fans being provided (Fig. 2) in the vestibules to circulate the aforesaid nitrogen to cool the work disposed therein in baskets 126. Charging and discharging.-The baskets 126 are charged and discharged in carriers 104, 105 moved between the appropriate vestibule and the transfer chamber 28 by transfer mechanism used for moving the plate 68. The transfer mechanism comprises parallel rods 72, 74 to which the plate 68 is fixed, shifted to and fro by wires engaging reels 84, 94 on axles 88, 96 interconnected by chain and sprocket gearing 90. The latter may be operated by a handle or axle or by a pneumatic motor (160, Fig. 2). Each carrier 104, 105 is articulated as at 108 to rod 72 and at 120 to a spring-tensioned rod 118 having a stop 125 engaging the plate 60 (or 50). Further movement of rods 72, 74 tilts the carrier transversely, where it is held by spring 124 and a transfer rod 39 moves the basket 126 over tracks 128 into the heating chamber 12 and eventually withdraws it therefrom. Vacuum and gas supply, Fig. 4.-Heating chamber 12 communicates with a vacuum pump through port 20 and the vestibule communicates with the same pump through lines 130, 132 controlled by valves 136, 138 and through line 134. Sealing assemblies 48 and 58 are connected to another vacuum pump through valve controlled lines 140, 142. Nitrogen from lines 146 is supplied to the vestibules by lines 148, 150 and also by line 152 branching into lines 156, 158, all lines being controlled by solenoid valves. While treated work is being cooled in one vestibule, the next basket is introduced into the other, this vestibule being then evacuated, supplied with nitrogen to bring it up to the pressure in the furnace, the basket then being transferred to the furnace. Doors 40, 42 are arranged to open automatically when pressure reaches atmospheric and closing said doors starts a timing motor controlling vacuum and gas supply operations automatically.

Abstract: 1,237,985. Frequency synthesizers. RCA CORPORATION. 10 Nov., 1969 [26 Nov., 1968], No. 54926/69. Heading H3A. A digital stabilized frequency synthesizer has two phase locked loops around the same controlled oscillator there being means in the first loop whereby phase of the oscillator is corrected at a rate which is the same or a submultiple of the channel spacing frequency and means in this loop to select the channel at which the synthesizer operates, and means in the second loop whereby the oscillator phase is corrected at a variable rate considerably higher than the channel spacing and always a submultiple of the synthesizer output frequency. Voltage controlled oscillator 1 is coupled by variable-ratio divider 22 to phase-discriminator 26 the second input of which is derived from reference oscillator 30 over fixed divider 32: the output of phase discriminator 26 controls the frequency of oscillator 1, via low-pass filter 36. For control of the short-term stability of oscillator 1, it is coupled in a second loop comprising variable ratio divider 40, ganged with divider 22 but only dividing by the first four significant figures set up in divider 22, phase discriminator 44 and high-pass filter 60. The second input of phase discriminator 52 is derived from crystal oscillator 46, whose frequency is controllable over a small range, and fixed divider 50. The output from phase discriminator 44 also controls the frequency of oscillator 46, via low-pass filter 56.
