Abstract: 1, 103, 948. Air turbine plant. CLARKE, CHAPMAN & CO. Ltd. July 28, 1965, No. 32180/65. Heading F1G. An air turbine plant comprises a compressor 1, the air from which is heated indirectly in an air heater 4, the heated air then passing to a turbine 2 which drives the compressor 1. The air discharging from the turbine passes through duct 7 to a combustion chamber 3 where the air is heated by combustion of fuel, the resulting combustion gases passing to the heat exchanger 4 for heating the air. The turbine 2 also drives a fan or blower 6 which supplies air to the duct 7 through which the air discharging from the turbine 2 is passing, the air from the blower mixing with the exhaust air and becoming heated thereby. A portion of the air from the duct 7 is subsequently tapped off through line 8 and is utilized for heating purposes. The amount of air tapped off may be equal to the amount supplied by the blower 6. The turbine 2 may also drive an electric generator 5. In a second embodiment a portion of the air discharging from the turbine 2 may be utilized to drive an auxiliary turbine which drives a blower the air from the blower being mixed with the air discharging from the auxiliary turbine and the resulting air mixture is utilized for heating purposes.

[Class 20 (iii)] The base 15 of a channelshaped sheet-metal runway of a vehicle window 5 is bent at 40 and the side walls 16 are severed from the base adjacent and above the bend and are also bent, as shown, to accommodate the front sloping edge of the window. Means, such as a supplementary frame 36, is provided to maintain the side walls and base in fixed relation to each other. The runway channel may, with the exception of its longitudinal beads 17 have a covering layer 20 of vulcanized rubber, and its base and window-engaging flanges 18 may also be provided with felt pads 21, 22. The lower portion 50 of the supplementary frame fits closely around the window channel as shown in Fig. 5, with its beads 52 gripping those of the window channel. The centre portion is of gradually increasing depth, while the upper portion is of uniform depth. This upper portion is formed by severing the side walls from the base, bending the base at 40, and then folding the inner edge portions 43 of the side walls around the back of the base. An extension 46 of the base may be folded as shown to grip the portions 43. As shown in Figs. 2 and 6, the beaded edges 37 of the centre and upper portions of the supplementary frame are adapted to grip the beaded edge 17 of the window runway or channel. Tongues 42 may be pressed out of the side wall of the frame to engage with and grip the base 15.

Title: Apparatus for measuring small variations in weight
IPC: G01G3/14
Filed: 1947-12-10
Abstract: 646,457. Electric indicating systems. FOX. BORO CO. Dec. 10, 1947, No. 32595. Con. vention date, Dec. 10, 1946. [Class 40 (i)] [Also in Group XVIII] In a device for measuring small weight variations in a heavy object (e.g. a dehumidi. fier) the latter is weighed on a machine having a weighted counterbalance being connected to strain a cantilever bar in proportion to the degree of unbalance. Resistance strain gauges fixed to opposite sides of the bar are connected in a Wheatstone bridge which is rebalanceable by a variable resistance calibrated to indicate changes of weight of the object. In Fig. 1 a dehumidifier 16 is placed on a platform scale 10 having a balancing arm 14 with the usual weights 22 and slider 24. A cantilever strain bar 30 carried by a rigid arm 28 is connected at its free end to the end of the balancing arm by a chain 32 and spring 36. A pair of similar wire-wound electrical strain gauges 40, 42 are bonded to the upper and lower surfaces of the strain bar, and connected in adjacent arms of a Wheatstone bridge, Fig. 2, having a variable resistance arm 52. Initially the weight of the dehumidifier is balanced by the weights and slider, the latter is adjusted to counterbalance the expected weight increase, and the bridge is balanced by adjustment of the resistance 52. As water is absorbed by the dehumidifier, its weight increases, reduces the strain on the bar, and again unbalances the bridge, which is rebalanced by resistance 52, the new value of which is a measure of the change in weight of the dehumidifier. The scale 22 may be calibrated directly in weight, taking the initial adjustment of the resistance 52 as zero. The strain bar may be attached to other parts of the scale, and the resistance changes may be measured by apparatus of the kind described in Specification 646,981. The invention is applicable to measuring the weight of gas compressed in cylinders.
