Title: Process for freeze drying coffee
IPC: A23F5/32
Filed: 1971-09-28
Abstract: 1347984 Freeze-drying coffee GENERAL FOODS CORP 28 Sept 1971 [8 Oct 1970] 45234/71 Heading F4G [Also in Division A2] In a method for obtaining darkened freezedried coffee, coffee extract is frozen, ground and dried by sublimation in a vacuum at a pressure of 350 to 650 microns of mercury for the initial 1 to 5 hours of the drying cycle, and at a pressure less than 300 microns for the remainder of the cycle. The pressure, which is preferably in the range 400 to 500 microns, may be thus maintained for the first quarter to half of the drying cycle. Particles of the ground frozen extract which pass through a 40 mesh screen may be removed prior to drying.

Title: Multi-terminal digital signal transfer systems
IPC: H04B3/00
Filed: 1973-10-04
Abstract: 1410842 Loop communication systems: digital transmission INTERNATIONAL BUSINESS MACHINES CORP 4 Oct 1973 [13 Dec 1972] 46305/73 Headings H4K and H4P In a loop communication system, the signals traversing each station are amplified without breaking the loop so that in the event of power failure in a station the signals merely suffer attenuation and are not lost. The signals are amplified by coupling a sample thereof through a directional coupler to an amplifier whose output is then superimposed via another directional coupler back on to the transmission loop. A directional coupler consists of two adjacent parallel printed circuit strip lines which are sandwiched between a pair of copper ground planes. A pulse signal travesing one line in one direction induces a positive and a negative pulse in the other line at its rising and falling edges respectively, the pulse pair being propagated in the opposite direction to said one direction. Receiver/repeater comprises in every station a coupler 42 which branches off a sample of each signal traversing the loop. The shown sinusoids represent a 1 bit per full wave, 0 bits being represented by absence of signal. The branchedoff signal is amplified and has its positive peaks clipped by circuit 52 whereafter it is coupled back on to the loop. It is ensured that the backcoupling occurs precisely in time with the originating signal by means of delay line 62 which is adjusted to compensate for delays via the amplifier 52. The local station picks off the signal from the amplifying branch 44 by means of a coupler 64, a driver 18 which converts the sinusoids into a sawtooth waveform, and a coupler 76 that produces a rectangular pulse in response to each rising edge of the sawtooth. Transmitter at each station consists of a coupler 26 that converts each incoming rectangular pulse into a pulse pair 20 which is used to gate on and off oscillations from a sinusoid oscillator 34. The gated oscillations have their negative excursions clipped and are then coupled on to the loop as sinusoids by coupler 36. It is very briefly mentioned that adjustable delay 40 represents a means for ensuring that new signals are injected into the loop during an empty time slot.

In apparatus for heating, cooling, drying, or otherwise treating a bed of fluidized particulate material in a treatment chamber 1, the material is agitated and conveyed along the chamber by at least one hollow screw conveyer flight through which a heat transfer medium is pumped. As shown, the chamber 1 is flat-bottomed, and has four hollow screw conveyer flights 2 along the length of the chamber, with their axes parallel and substantially horizontal, and their flights intermeshing. They are driven synchronously by external driving means, not shown. Groups of porous panels 8 are arranged in the floor of the chamber, each group having three panels, one below each screw flight interfold. A fluidizing gas is supplied to chambers 10 below the panels 8 by supply ducts 11, which may be connected to a supply manifold 12. Material to be treated, e.g. gypsum to be cooled, enters the chamber at one end, through a top inlet, not shown, and leaves at the opposite end, through an outlet in the floor, not shown. The fluidizing gas may be heated or cooled before injection into the chamber, to assist the action of the heat transfer medium passing within the screw flights, and, if desired, a gas reactive with the material may be used for a particular treatment. The groups of panels 8 may be supplied by independent controllable sources to give graded temperature conditions through the chamber, or a single large porous panel may be used in place of the separate ones. Specification 737,118 is referred to.

Continuously moving steel strip 10 e.g. for making into razor blades is hardened by heating the strip e.g. to 2000‹ F. (1093‹ C.) to produce austenite and cooling the strip rapidly to convert the austenite to martensite whilst subjecting it to a differential stress to reduce transverse curvature and flatten the strip, preferably by bending the strip over a sharp edge 150 as shown e.g. while it is at a temperature of 320‹ F.
