Abstract: 1,238,854. Thermal storage heaters. R. G. B. GRANT. 4 June, 1969 [5 March, 1968], No. 10604/68. Heading F4U. In a forced air electric thermal storage heater the core is formed of blocks 13a each of which is in the form of a rectangular parallelepiped with an open channel on one face, the channels serving for the flow of air and for the location of heating elements. A fan 21 draws hot air from the core and cold air from an inlet chamber in proportions determined by the setting of a damper 19. The damper is controlled by a bimetal 18 in a hot air duct 16 and is arranged to close if the bimetal should fail. A baffle 25 in the core inlet chamber 14 encourages turbulence and traps dust which might otherwise fall and enter the fan. The fan discharges into a plenum 23 to which warm air central heating ducts are connected. In an alternative embodiment (not shown), the fan may discharge downwardly into a separate plenum.

Abstract: 1,239,571. Making envelopes. JOHN DICKINSON & CO. Ltd. 10 March, 1969 [7 Feb., 1968], No. 6074/68. Heading B5D. Envelopes &c. each having a pair of cooperating closure flaps are fed, in stepped formation so that only the regions requiring gumming are exposed, through a machine to an adhesive-applying station where at least one strip of adhesive is applied to the closure flaps, whereafter the path of the envelopes is altered so as to break the line of adhesion between each pair of flaps. The method is particularly applicable to envelopes wherein the upper closure flap is an extension of the front wall of the envelope, and the lower flap is of narrower width and formed by cutting two slits in the back wall a short distance from the lateral edges of the envelope. The adhesive surfaces may be protected by folding the upper and lower flaps so that the adhesive lies against the back of the front and back walls respectively. The crease so formed across the lower flap also aids the separation of the two flaps after applying adhesive. As shown, envelopes fed by rollers 1, 2 receive a stripe of glue, equal in width to the lower flap, from an adhesive-applying roller 3. After feed rollers 9, 10 the path of the envelopes is altered by a roller 11 that can be adjusted around roller 12. Further rollers 13-16 rotate at a faster speed to increase the spacing and break adhesion between successive envelopes; alternatively the envelopes may be separated before their path is altered. Rollers 9, 11, 13, 15 may each be formed from two short rollers that bear only on the lateral, ungummed edges of the envelopes. Adhesive may be applied by a roller, wipe-on box, or by spraying and may be selfsealing or moisture activated.

Abstract: 1334521 Ejector seats DEFENCE SECRETARY OF-STATE FOR 28 June 1971 [1 July 1970] 31879/70 Heading B7G An ejection seat 1 incorporates a rocket motor 4 equipped with a thrust-directing tube 16 which can be rotated to vary the direction of thrust 22 in accordance with the aircraft speed at the moment of ejection. At speeds below a preselected value a spring-biased lever 11 engages a notch 9a in a disc 6 secured to the motor 4 to retain the tube in the Fig. 1 position; if the speed at ejection exceeds this value then lever 11 is pivoted out of notch 9a by a twoposition plunger 20, disc 6 is rotated by a spring 10 and lever 11 is caused to engage a notch 9b so that the thrust line 22 is rotated anti-clockwise (Fig. 3, not shown). Plunger 20 is controlled by an airspeed sensor 17; it is spring-loaded towards an extended position (Fig. 2, not shown) and is restrained in the retracted position of Fig. 1, by a stop 21 on the seat and by a bellows-operated catch which is designed to be inoperative at speeds above the preselected value. Upon ejection, plunger 20 slides free of stop 21, but at speeds below the preselected value it is still retained by the catch so that ejection continues with the thrust line passing through the C.G. 2 of the seat and its occupant. However, at speeds above the preselected value, the catch is inoperative, so that the plunger is free to extend and pivot lever 11 out of notch 9a; disc 6 and hence tube 16 can then rotate as the seat rises. The arrangement may comprise more than two tubes 16, and the tubes themselves may be connected to the motor by flexible tubing or by gastight rotatable bearings.
