Patent GB-1230178-A (GB)
IPC: B65D75/32
Filed: 1968-05-16
Abstract: 1,230,178. Food package. DOW CHEMICAL CO. 16 May, 1968 [17 May, 1967], No. 23433/68. Heading B8C. In a package including a container and a food product, such as luncheon meat, cheese, frankfurters and chili, the container comprises a base 18, Fig. 2, of plastics foam and a self-supporting cover 42 hermetically sealed to the base and preformed to the shape of the enclosed product, to obtain overall contact between the product and cover, the base being self-supporting in that it is not deformed by its own weight. The base 18 may comprise a laminate of a film or films of plastics, 22, e.g. " Saran " (Registered Trade Mark) or polyvinylchloride and a plastics foam ply 24, e.g. of expanded polystyrene or polyethylene, having a peripheral groove 28 and a circular fold 40. The cover 42 is preferably transparent and of polyvinylchloride but may be of a layer or multilayer of other plastics, e.g. Saran or a Sarancoated polystyrene. A peripheral lip 48 of the cover is located in the groove 28 of the base and sealed either with a soft tack adhesive such as a copolymer of 50% styrene and 50% butadiene or a heat sensitive adhesive, or by heat alone, for example when the film 22 comprises a biaxially-orientated film, which becomes randomly-orientated in the region of the seal on application of heat, thus forming a weakened tear line. Figs. 4 and 5 show alternative configurations of the cover and base peripheries. In another embodiment, Fig. 6 (not shown), the cover is secured to the base along one side by staples and scored to provide a hinge, the opposite side being provided with thumb-sized cut-outs (98), and a hole (96) for suspending the container.

Abstract: 1,233,944. Measuring gas flow electrically. TEXAS INSTRUMENTS Inc: Oct. 31, 1968 [Oct. 31, 1967], No.51721/68. Heading G1N. [Also in Division F4] An apparatus for sensing differences between the relative velocities of fluid flowing in separate paths comprises first and second self heated thermistors, having a sharp transition characteristic, and a circuit including a sensor responsive to a difference in power consumptions of the thermistors and thereby to sense a difference between the fluid velocities in the paths. The arangement may be utilized to sense frost build up in a refrigerator. A fan (23) Fig. 1 (not shown) circulates air part of which passes through an evaporator (17) and past a thermistor TH2, and the remainder through a closed path past a thermistor TH1. The thermistors are connected to an A. C. supply through anodes D1-D3 which connect them in parallel on one (heating) half cycle and in series on the opposite half cycle (measuring). When the evaporator is substantially free of frost, the thermistors have approximately equal resistance hence the voltage across a Zener diode Z1 is insufficient to cause conduction of a thyristor Q1. When the evaporator becomes clogged, thermistor TH2 increases and thermistor TH1 decreases in resistance hence on positive half cycles of a supply the voltage across TH2 will increase hence causing thyristor Q1 to conduct and energize a relay coil RYW which disconnects the compressor circuit and energizes a heater to defrost the evaporator. The inductance of coil RYW maintains the thyristor forward biased on opposite half cycles. A thermal relay may be employed if a smoothing capacitor is connected between line L5 and tap 37. In an alternative arrangement Fig. 3 (not shown) the thermistors are connected in a parallel circuit including the heater windings (H3, H4) of a differential thermal relay. The thermistors may be constructed of a semiconductor material e. g. barium titanate doped with lanthanium, which has a transition temperature above which the resistance of the material rises relatively abruptly i.e. a negligible change of temperature produces a large change of resistance above the transition temperature.

Abstract: 1,256,863. Moulding seat covers. IMPERIAL CHEMICAL INDUSTRIES Ltd. 4 March, 1969 [11 Dec., 1967], No. 56225/67. Heading B5A. [Also in Division A4] Seat covers, for particular use in cars, are vacuum formed on a planar mould having projecting or recessed regions only in the areas which form the parts of the sheet corresponding to the edges of the seats to be covered. In this way the necessity to deep draw the cover to the shape of the seat together with its attendant disadvantages such as curling or uneven stretching is avoided. In the particular embodiment, the mould is provided with two "humplike" projections, the facing edges of which are straight and the other edges of which are curved. The sheet may be single-layered or laminated and in a particular example comprises a PVC layer and a cellular layer.

Abstract: 1,264,192. Controlling burners. W. H. MOORE. 3 Feb., 1969 [6 Aug., 1968; 3 Jan. 1969], No. 5741/69. Headings F4F and F4T. [Also in Division F1] An oil burner control system comprises a source of alternating current, a blower and motor 24, a fuel supply, electrodes 40, 42 forming a spark gap, a thermostatic switch 38 and a control circuit 33 including a spark generator 44, means providing direct current for the control circuit from the A.C. source, a resistor-capacitor time delay circuit connected to the control voltage through the thermostatic switch 38, a flame sensing device 50 having high resistance when dark, low resistance when illuminated, connected across the capacitor of the time delay device to discharge it in response to illumination, the control circuit also comprising a power switch for connecting the source to the motor and the spark generator, the power switch being rendered conductive in response to the closure of the thermostatic switch and the time delay circuit also being energized, and the power switch being rendered non-conductive in response to the charging of the said capacitor to open the circuit to the motor and the spark generator when there is failure to ignite. The burner has a nozzle 26 which emits a fine cone spray of oil and the air blower produces an airstream in the direction of the axis of the cone, the spark gap being located immediately outside the cone spray and within the airstream and the plasma discharge being deflected by the airstream into the cone spray to ignite the burner. In operation, when thermostat 38 closes in response to a demand for heat a relay 68 is energized and contacts 70 close to allow capacitor 84 to charge through contacts 70, a circuit-breaker 72, heater 74, diode 80, resistor 82 and the primary winding 86 of a high-voltage transformer 88, the secondary of which is connected to the spark-gap. So long as the flame sensor 50 remains dark a silicon-controlled rectifier 102 is triggered to discharge capacitor 84 through the winding 86 and cause a spark. The capacitor also causes heater 74 of a relay 75 to close contacts 76 to operate a relay 106 and the heater 72B of circuit-breaker 72 continues to heat up but when relay 106 operates heating of heater 72B is discontinued and contacts 112 close to apply power to the motor and fuel pump. On illumination of sensor 50, due to ignition, resistance is lowered and triggering of the SCR ceases, the capacitor remains charged and current through the circuit-breaker is reduced to prevent it operating. If flame is not established the circuit-breaker 72 operates to open contacts 72A on a latching arrangement so that the burner shuts down until the circuitbreaker is reset manually. If the sensor 50 is illuminated when a demand for heat is first made its low resistance prevents triggering of the SCR 102. In a modification switching functions are performed by semi-conductor devices.

An annular gasket 30 is sealingly engaged between the collar shoulder 28 and the rim 16. The outside surface of the ring and inside surface of the collar are of complementary frusto-conical shape in order to provide clearance for pivotal movement of the arrangement during attachment and also to cam the outer surface of the ring radially inwards to form a tight fitting joint. The arrangement may be of moulded plastic, or moulded plastic incorporating a metal pouring spout.
