Title: Combined room heater and ventilator
IPC: F24H3/04
Filed: 1959-08-25
Abstract: 867,162. Electric fan heaters. NUTONE Inc. Aug. 25, 1959 [Oct. 1, 1958], No. 29068/59. Class 39(3). [Also in Groups X and XXV] A combined room heater and ventilator comprises a motor adapted to drive two fan blades which are mounted one above the other within a cylindrical casing which has an exhaust port 45, Fig. 2, in its wall at its upper end and is open at the lower end. The upper fan, the exhaust fan 41, has a capacity several times that of the lower fan, the convection fan 36, so that in operation with the heating elements 25 out of circuit air is expelled through the outlet 45. When the heating elements 25 are energised a bimetallic spring 55, Fig. 3, expands and causes a spindle 57 to rotate thus causing a gate 50 to close the exhaust vent, and render the exhaust fan ineffective; in this way the convection fan drives a draught of air over the heating elements and out through the open end of the casing. The device is preferably mounted in a ceiling of a room. Alternatively the gate 50 may be operated by means of a solenoid arranged in the heating circuit, which contains an indicator lamp to indicate when the heating elements are energised.

Abstract: 663,777. Erecting walls. SOMMERFIELD, A. Nov. 10, 1949 [Nov. 10, 1948], No. 29185/48. Class 20(i) Walls or wall sections are built up from any suitable material and to any desired arrangement of parts such as window and door frames, fireplaces &c. in a horizontal position on a platform 7 which is subsequently raised to a vertical position to position the assembled wall over a prepared foundation 14 to which it is then grouted. The platform 7 is eccentrically mounted on discs 6 provided with handles 6a, the discs being mounted on a shaft 5 carried by upstanding brackets 4 at the front of a wheeled chassis or trolley 1. When the grouting has set the handles 6a can be operated to move the frame downwards and outwards from the wall, the trolley then being moved along rails 15 to bring the platform into position for casting a further section of wall. The platform 7 has arcuate grooved portions 8 guiding a cone 11 operated by a winch 10 and secured to the front of the platform whereby the platform may be raised to its vertical position and lowered therefrom. Retaining members 13 are provided at the front of the platform to hold the formed wall as the pl'atform is raised. A number of trolleys may be placed side by side with the platforms connected, to form large sections of a wall. Two opposite walls of a house are preferably formed and raised at a. time and the tops interconnected by beams cast in situ. The platform 7 may be long enough to accommodate a wall of two stories height. The wall may comprise upper and lower precast beam members, the lower beam having funnel shaped openings for pouring the grouting concrete. The wall may consist of layers of brick, concrete, plaster, with insulating material between the layers, e.g. lead, for protection against radioactivity. The platform 7 may be provided with heating means to speed up the setting of the wall. The platform may also be curved up towards its rear end, for the erection of an arched hut, a preformed keystone being located between the upper edges of two opposite walls of the hut. According to the Provisional Specification the platform is carried by a shaft on a working frame, the shaft being adjustable in relation to the rear of the trolley by screw means.

Abstract: 501,079. Arc lamps. STAHN, A. Oct. 26, 1937, No. 29220. Addition to 444,241. [Class 39 (i)] In a modification of the invention described in the parent Specification, the operating member 16 is provided with a cam or similar element 17 which on actuation first releases a swingable electrode holder 4 and allows the electrodes 1, 2 to contact, and on release, by displacing the axis of rotation 8 of the swingable electrode holder, separates the electrodes by a predetermined distance, the swingable electrode being fixed by the operating member in its new angular position in order to impart to it a parallel displacement. The electrode holder 3 is fixed to and insulated from the lamp frame 5, and the holder 4 is secured to and insulated from a curved arm 6 which is integral with a counterweighted arm 11 and a sector shaped arm 12. The arm 6 is pivoted in bearings 9 carried by a pair of leaf springs 10 constituting a spring parallel motion. The shaft 15 connecting the operating member 16 with the cam 17 is spring biassed so that its largest radius is directed upwards and a spring-depressed braking plate 19 is forced against the sector 12 to prevent rotation of the arm 6. A spring 21 anchored to the frame and to an eccentric point on the arm 6 rotates the electrode 2 into contact with the electrode 1 when the cam releases the braking plate 19. Downward movement of the bearing 9 is limited by an adjustable stop 22. A number of pairs of electrodes may be controlled simultaneously by the provision of a widened plate 19 contacting with a number of segments 12.

Corresponding leg laminations in each pattern may be of the same length or may be progressively longer towards the outer edges of the rectangle according to the disposition of the butt joints, i.e. whether they are, in general, at right angles to the plane of the leg laminations, or at an angle thereto. The butt joints in the yoke portions may correspondingly be at right angles to, or at an angle to the laminations in the yoke. The right angle corners of the core may be formed by bending the ends of the yoke laminations or by using right-angled insert pieces. Specification 622,538 is referred to.

Abstract: 1360859 Digital transmission; synchronizing HONEYWELL INFORMATION SYSTEMS Inc 23 June 1971 [29 July 1970] 29983/71 Heading H4P A central processor working to one or a plurality of multiplexed terminals has a detector which on any gap between message characters inserts fill characters preferably of predetermined pattern to maintain synchronism. Message characters loaded into buffer 35 from a processor memory (not shown) are transferred parallely through gates 38, 40 to shift register 41 and are then clocked serially to line by shift pulses also stepping counter 45 which provides an end of character signal. This resets flip-flop 26 giving a 1 on 26(0) which enables AND 21 already primed from flip-flop 17 thus causing OR 23 to set flip-flop 26 giving a 1 on 26(1). Through delay 22 and inverter 19 this resets flip-flop 17 providing an input to AND 16 which if receiving other inputs requests another character from the memory. If there are no further characters in the memory, flip-flop 26(0) output remains at 1 which together with 1's from flip-flop 28 and 17(0) enables AND 30 and hence AND gates 36a-36h to pass a fill characters through gates 40a-40h Flip-flop 17 remains reset until the processor is ready to send another message character. A timing diagram for the various operations is given in Fig. 3 (not shown).
