Title: Improvements in or relating to the processing of coffee
Inventor: MOON ANTHONY JAMES ROBERTSON
IPC: A23F5/10
Filed: 1962-12-20
Abstract: 1,024,214. Preserving coffee. KENCO COFFEE CO. Ltd. Dec. 17, 1963 [Dec. 20, 1962], No. 48,094/62. Heading A2D. In treating freshly roasted coffee beans or ground coffee to remove occluded gases, which might distend or burst tins or flexible plastic packages in which the coffee is preserved, the roasted coffee is fed, through a vacuum-sealable port 2, into a container 1, Fig. 1, having a vacuum-sealable discharging port 3, which is closed, and a valve 5, which is also closed and is provided with a filter 4. The valve 5 is detachably connected to a manifold 9, Fig. 2, comprising valves 7 and 8 and a vacuum-pressure gauge 6. The valve 7 is connected to a vacuum pump (not shown). The valve 8 is connected to means for supplying an inert gas, such as carbon dioxide or nitrogen, at a pressure slightly above atmospheric pressure. The port 2 is then closed and the valves 5 and 7 are opened, so that air is evacuated from the container until the pressure therein equals the vapour pressure of the coffee. Valve 7 is then closed and valve 8 is opened, to admit inert gas into the container. Valve 8 is closed and the container is again evacuated to remove most of the residual air, and sufficient time is allowed for occluded gases to be evolved from the coffee. The progress of the evolution of occluded gases is observed on the gauge 6. If the coffee has been well roasted and contains a relatively large amount of occluded gases, a third evacuation of the container 1 is made at this stage. The valve 8 is opened, the container is flushed with inert gas and the discharge port 3 is then opened so that the treated coffee is discharged for packing, in tins or flexible plastic packages, in the presence of inert gas. As shown in Fig. 3, a plurality of containers 1 are arranged in a circle around a central shoot 13. Each container has inlet and outlet valves 11 and 12 instead of ports 2 and 3. Coffee is fed into the containers through a spout 14, which can be rotated around the axis of the circle. Treated coffee is discharged, through the valves 12, into the shoot 13. Operation of the valves may be remotely controlled by conventional hydraulic mechanism.

Abstract: 1,208,018. Microwave heating. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 30 Oct., 1967 [2 Nov., 1966], No. 49141/67. Heading H5H. Apparatus for heating webs (3, Fig. 1) passing through longitudinal non-radiating slots (2) in opposite wide walls of a rectangular section waveguide (1, Fig. 1) is provided with a movable reflection system to influence the standing wave and hence obtain uniform web heating. This is achieved by satisfying the conditions that (a) the phase of the standing wave varies proportionally with time; and (b) the amplitude of the reflected wave remains constant. In Fig. 2, the reflection system comprises an insulating tape 21 supporting reflecting discs or pins 23 of conductive or dielectric material at a mutual distance of #w/2. Discs 23 pass at constant speed through a further longitudinal slot 24 in one wide wall of the waveguide over a distance #w/2. In Fig. 4, the reflection system comprises a tape 31 of dielectric material moved in the direction 36 at a constant speed through further longitudinal slots 2a in the wide walls of the waveguide and at right angles to the longitudinal axis 35 of the waveguide. Rows of reflecting discs 34, of conductive or dielectric material, are provided such that the distance between the first disc 34<SP>1</SP> of a row and the last disc 34<SP>11</SP> of the preceding row in the direction of axis 35 is approximately #w/2 - a, where a is the distance between adjacent discs. Conditions (a) and (b) can only be realized effectively when the generator (4, Fig. 1) always supplies the same output power to the load independent of load impedance. Due to the movement of the reflection system, the load impedance varies so that the power supplied by the generator varies. An impedance transformer may be provided in order that the load matches the generator output such that the generator output power varies little. Alternatively, the amplitude and/or phase may be adapted to the variation of the output power, e.g. by varying the depth of penetrating of discs 23, by providing discs 34 in one row with different dimensions, or by arranging discs 34 in curved lines.

Abstract: 1,160,990. Voltage measurement; indicating apparatus. M. POSSATI. Nov. 2, 1966 [Nov. 5, 1965], No. 49209/66. Headings G1J and G1U. In a potentiometric voltage indicating system a flexible belt 3 is driven in accordance with the difference between an input to be measured V and a voltage V1, corresponding to the position of an index 1 on the belt, picked off from a potential divider 23 driven by the belt. The voltages V and V1 energize solenoids 15, 16 which differentially attract the pivoted yoke 12 to engage the belt between one or other of the pairs of rollers 8, 10 or 9, 11. The rollers 8, 9 are continuously rotated in opposite directions. At the position where the index correctly indicates the input, V1 and V are equal and the yoke 12 engages neither drive roller. At this instant a brake is applied to the belt by the release of solenoid 22, which is normally actuated by the difference V-V1.

Abstract: 1480341 Impulse transmitters GENERAL ELECTRIC CO Ltd 25 Oct 1974 [25 Oct 1973] 49698/73 Heading H4K In an electric impulse transmitter for attachment to a telephone line at terminals 6 and 7 and in which digit values of a number to be called are entered at 1, temporarily stored at 2 and transmitted over the line as make and break impulses, e.g. by contact 4 of a relay 2, electric circuitry 13, 22 provides a clear signal to the store 2 when the line current becomes zero except during the break periods of an impulse train. When the line is looped and a push button of the set 1 is depressed a capacitor in the power supply circuit 8 charges from the line. This actuates momentarily a clock pulse generator 10 which provides a steady voltage between lines 11 and 12. Hence 23 is turned ON and 15, 16 are held non-conducting to apply the potential of line 12 as a clear and re-set signal over the path 24 to the store 2. When 23 subsequently becomes non-conducting and 16 and 15 are turned ON, the clear and re-set signal ceases and the first digit value is entered into 2. As long as this digit value or any subsequent one is held in store 2, the latter generates a signal to the power supply circuit 8 which thereby holds the generator 10 in operation. During interpulse loop breaks transistors 16 and 15 are powered from the drive circuit for the relay 3, via diode 25 and resistor 26.

Abstract: 1310730 Automatic temperature control BORG-WARNER CORP 20 Oct 1970 [17 Nov 1969] 49825/70 Heading G3R In the temperature control of a living space the output voltage of a single temperature detector circuit, and which varies as a function of the temperature sensed, is compared with a plurality of reference values (voltage levels) each associated with a respective heater or cooler unit which are successively turned ON (or OFF) when a predetermined relationship exists between the sensed temperature and each respective reference value. In Fig. 3 the temperature detector is a thermistor 121 in a bridge circuit the unbalance temperature representative voltage of which is fed to an operational amplifier 111 having feedback circuits to time average the positive and negative inputs thereto and produce a temperature representative output signal. A feedback loop including C118 is provided to introduce a timelag and prevent rapid cycling of the temperature control or switching ON heaters or cooler as a result of spurious temperature transients. The amplifier 111 output on a line 114 is fed to a plurality of comparators 141 to 146, the second input of each of which is a respective reference voltage level derived from a divider unit 115. When the temperature sensed is at a desired temperature the voltage on line 114 corresponds to the voltage between junction point of R159 and R169 and a supply line. The response delay of the amplifier 110 is not fixed but is proportional to the severity of the sensed temperature change. Thus depending upon how much and how quickly the detected temperature increases from the desired or balance level, successive ones of the comparators 143, 142, 141 will produce an output as the resulting positive voltage on line 114 reaches the respective reference voltage level-input. The comparators outputs thus will trigger respective triacs to turn ON respective coolers to reduce the controlled temperature toward the desired value. Likewise depending upon how much and how quickly the said temperature decreases below the desired level such that the line 114 voltage goes progressively more negative than the reference voltages of comparators 144, 145, 146, the heating units are successively turned ON. There will be no output from any comparator while the temperature signal voltage on line 114 does not reach the reference inputs to comparators 143, 144 and neither heaters nor coolers are operated. The comparators may be Schmidt triggers circuits and electromagnetic switches or relays controlled by transistors, may be used instead of the triacs Fig. 4 (not shown). A further operational amplifier 106 may be provided to produce a temperature indication on a meter 90. The reference voltage levels may be derived from the bridge circuit containing the thermistor Fig. 2 (not shown).
