Filed: 1970-02-13
Abstract: 1305455 Moulding plastic materials KRAFTCO CORP 13 Feb 1970 7139/70 Heading B5A [Also in Division B8] Apparatus for dispensing measured quantities of material, e.g. cream cheese or butter, comprises a wheel 12 having a plurality of circumferentially spaced measuring chambers 16, a reciprocable piston 18 extending into each chamber and means whereby the volumes of material dispensed from the chambers may be controlled individually or collectively. Each piston comprises a driver 96 slidably mounted on a pedestal 82 and carrying a cam roller 104 received within a track 106 in a plate 108, and a head 94 movable relative to and attached to the driver by springs 98. A fine adjustment screw (100), (Fig. 3, not shown), is provided on the driver for varying the relative positions of the head and driver. Each pedestal 82 is biased by springs 90 towards shaft 14 and carries a stop 20 for limiting inward movement of the head. A collar 60 movable axially of the shaft by rotation of handle 24 supports wedges 78, each engaging an inclined surface 86 in a respective pedestal. The wedges are movable separately in a direction parallel to shaft 14 by screws 22 to adjust the positions of the stops individually whereas movement of the handle 24 adjusts the stops simultaneously. In use material from a hopper 26 (only partially shown) enters a chamber during its travel between points B and C, and after passing point A each head 94 is moved to a position in which it extends slightly from its chamber to permit a wire 30 to separate the material from the head. The separated material falls on to a wrapper in a conveyer 32. Absence of a wrapper sensed by a light source and an associated photo-electric cell due to light not being reflected by a wrapper causes a double acting piston and cylinder 152 to pivot an arm 144 carrying the wire 30 into a position to permit the material to be carried by the head until it is separated by a scrapper 34 and deposited on a waste conveyer 36. A sealing shoe 54 mounted on the lower end of the hopper is held against run 42 of the wheel by clamps 134 each comprising an inverted U-shaped member with each leg carrying a pair of rollers 140 which engage the inside of the rim, and a clamping bolt 142. The hopper outlet includes a plurality of baffle plates 28 each provided with rows of holes 128.

Title: Temperature control and measurement process and apparatus
IPC: G01K5/32
Filed: 1972-04-20
Abstract: 1340170 Automatic control of temperature and pressure MONSANTO CO 20 April 1972 18424/72 Heading G3R The temperature in a reaction vessel is controlled in accordance with a calculated temperature signal derived from measurements of the actual temperature and pressure in the vessel. Using a signal with a pressure component enables changes in the reaction temperature to be rapidly detected and corrected. In the arrangement of Fig.1, liquid and vapour phases are present in a closed reaction vessel. The pressure of the vapour phase is continuously measured, and the resulting signal multiplied by a pressure compensation constant and added to a variable correction factor. The output from the adder circuit is compared with the actual measured temperature signal to produce an error signal which is time-integrated and divided by a time constant to form the variable correction factor. The adder output also constitutes a calculated temperature signal which is compared with the desired temperature set signal, forming an error signal which controls heat flow from the reaction vessel. The signals may be transmitted by pneumatic, hydraulic or electrical connections and the calculations and comparisons may be performed by a digital or analog computer. The temperature of the liquid phase may be measured by a thermistor bridge, and temperature control may be effected by varying flow in a cooling jacket, using a reflux condenser, or adding or removing catalysts, inhibitors, reactants or products. The system is suitable for use in controlling polymerization reactions.

Filed: 1970-06-23
Abstract: 1350068 Exercise monitoring device; selective signalling J S S STEWART 22 June 1971 [23 June 1970] 30343/70 Headings G4H and G5G A physiotherapy control device includes a stepping register 31, at least one input terminal to which sensors 7 may be connected, a comparator 44 or 45 for each input terminal for providing an output signal when the signal from the respective sensor exceeds a predetermined level, means enabled when said register is in a first particular state ( or 2) to apply said output signal to an input of a counter means 40 for stepping said register into a further state (2 or 3) when the count registered by said counter reaches a predetermined value (as stored at 48 or 49), a timer 41 enabled when said register 31 is in a second particular state (3) for stepping said register into another of its states (1) when a predetermined time measured by said timer (and selected at 9) has elapsed and indicating means (2-4) for indicating the state of said register 31. The invention is described for monitoring and instructing patients engaged in performing for example calf exercises and deep breathing, the sensors 7 in this case having a pedal ergometer and a hand held spirometer respectively. In operation, potentiometers 14 and 15 are adjusted to provide desired reference voltages to the comparators 44 and 45 and switches 9, 16, 17 and 10 are adjusted to select desired prestored values for time intervals and counter operating values. With the register 31 in state 1, instructions are given by displays 2 and 3 being illuminated and AND-gates 33, 46 are opened for counting the preset number of signals from sensor S1. When the counter 40 reaches the number stored at 48, register 31 is stepped on to state 2 for a similar procedure to occur in respect of deep breathing sensor S2. Stepping of register 31 to state 3 causes timer 41 to operate, after the preselected delay, to return the register to its initial state for the above cycle to start again. After a preselected number of cycles counted by counter 50 the machine is switched off. A timer 39 is provided for causing a warning light 19 to be illuminated if a sensor signal is not received within a predetermined time interval when the register 31 is in states 1 or 2. The displays 2-4 may be replaced by tape-recorded instructions. The number of sensors and register stages may vary from one upwards.

Title: Industrial boilers

Abstract: 1355054 Burning solid fuel and/or fluent fuel; burner controllers G W B BOILERS Ltd 21 Sept 1971 [22 Sept 1970] 44973/70 Headings F4B and F4T In a boiler furnace having a burner, a grate and means for feeding solid fuel to fall on to or towards the grate, the fuel feed and the burner are controllable so that in operation, the fuel feed or the burner can operate alone or both can operate together. A cylindrical combustion chamber with a burner at one end 26, is surrounded by a water jacket with two passes of smoke tubes 34, 36 leading to a chamber 37 having a grit arrestor 38 and flue 39. Solid fuel, such as wood waste, is fed from a hopper having an endless belt floor to a screw feeder to a pneumatic feeder connected to a conduit. From the conduit 11 wood waste passes to an inlet tube 12 leading through the boiler shell to a funnel shaped outlet 20 above a grate 25 in the combustion chamber. The tube 12 is surrounded by jacket 22 receiving pressure air from the conduit 11. Tangential inlets 21 at the top and bottom of the tube 22 ensure that the solid fuel is evenly distributed over the grate 25. Air from a blower is fed below the grate at A, and through a conduit 40 to the combustion chamber above the grate. Fuel residues from the grit arrester 38 are returned to the combustion chamber through the air conduit 40. Refracting rubble is supported in the grate 25 so that the wood waste forms a fluidized bed. The furnace is controlled by a system comprising two photoelectric cells, 45, 46, Fig. 3B, directed towards a flame in the combustion chamber, and towards the burner flame tube respectively. The detector 46 is shielded from the combustion chamber so that it gives an indication as to whether the burner is alight, regardless of whether wood is burning in the combustion chamber. These flame detector devices control the oil supply line 28. A programmed timer 49 controls both the wood and oil supply lines 11, 28. At start up, the timer control allows only oil to be fed to the furnace, after purging with air, and a first low rate of supply is maintained, subject to sensing of a flame by detectors 45 and 46. After a predetermined time, the oil supply is increased to that required for operation. After a further time interval, the oil supply is reduced and wood is fed to the furnace, the feeds being maintained while the flame is sensed by detectors 45, 46. The oil supply is then cut off under the control of the timer and the wood feed is increased and maintained while detector 45 senses a flame. A failure of sensors to detect either a wood flame alone, or both an oil or wood flame when required cuts off the appropriate feed lines, and returns the timer to the starting position to purge the furnace with air, and restart it.
