Title: A bearing device for pivoted windows
Inventor: BENGTSSON SIGURD WALTER
IPC: E05D7/085
Filed: 1969-03-11
Abstract: 1,204,304. Horizontally pivoted windows. S. W. BENGTSSON. 11 March, 1969 [11 April, 1968], No. 12730/69. Heading E2F. A bearing device for horizontally pivoted windows comprises a first bearing element A secured to the frame and having two bearing cups 14, 15 and a second bearing element B secured to the window and having two bearing pins 39, 40, the construction being such that in closed position the window is carried only by pin 39, upon opening to a predetermined ventilating position is carried by both pins, and on further opening is carried by pin 40 only. The invention resides in the provision of a first blocking member 26 movable into bearing cup 15 to prevent pins 40 being moved into the cup and a second blocking member 41 secured to element B and adapted to permit movement of pin 39 out of cup 14 only when pin 40 is seated in cup 15. As shown, 26 is a pin axially movable by a handle 34 into cup 15 and is spring biassed into the cup. Blocking member 41 is a projection on element B and extends into a recess 19 in braking runner 18 which slides in arcuate channel 17 whose centre of curvature is the centre of cup 14. When pin 40 is seated in cup 15; Fig. 10, element 41 is aligned with an arcuate slot 23 having its centre of curvature common with that cup and, on pivoting about pin 40, element 41 moves freely along this slot. In the blocked position, Fig. 9, element 41 is not so aligned and abuts the side of channel 17. By rotating the window through about 90‹ pin 39 is removed completely from channel 12 and the window may be removed from the frame. To assist in replacing the window, pin 40 may be bevelled at its end whereby the pin 26 is automatically displaced against its spring when pin 40 is inserted into cup 15.

Title: Apparatus for making corrugated flexible hose
Inventor: PADGETT PHILIP MARCUS
IPC: B21C37/12
Filed: 1953-05-07
Abstract: 727,103. Coiling helically-jointed tubes. TITEFLEX, Inc. May 7, 1953, No. 12802/53. Classes 83 (2) and 83 (4). Apparatus for making helically wound corrugated tubing includes supporting means on which a longitudinally corrugated strip is wound in a helix with edges of adjacent convolutions forming a seam and a roller with spaced fins and grooves fitting into the corrugations of the tubing on the supporting means, the fins being arranged to crowd the corrugations towards the discharge end of the supporting means. Longitudinally corrugated strip fed to a mandrel 11 and guided by a stationary cam element 65 is caused helically to wind on the mandrel, with the edges 61, 63 of adjacent convolutions interengaged, by a ribbed roller 16, a shoe 18 (not shown) and two further ribbed rollers 26, 27 (not shown) angularly spaced around the mandrel 11. The mandrel 11 comprises, at its inner end, a tapered portion 53 widening towards the discharge end and terminating in a shoulder 54 followed by a thinner cylindrical portion 55, then a further tapered portion 57 widening to a shoulder 58 and finally a thinner cylindrical portion 59, a hole at the outer end of which being used for lacing the strip when commencing winding. The first three ribs, or fins, 67 of the roller 16, which are integral therewith and are all of the same width, serve to interlock the helical tube seam. The other fins are formed as washers 72 separated by spacers 74 clamped by a nut 78 on a reduced diameter cylindrical part 70 of the roller. The spacers 74 are all of the same width as are the first few fins 72, but the other fins 72 decrease in width towards the discharge end of the roller, the last fin being located just past the shoulder 54 of the mandrel 11. The arrangement is such that the decrease in width of the fins 72 decreases the pitch of the corrugation and crowds the seams together; as the tubing is pushed over the tapered part 57 of the mandrel the corrugations come into contact at the top and bottom and as the tubing is pushed over the shoulder 58 the corrugations spring apart a little. The crowding of the corrugations may be effected entirely by the fins 72.

Title: Improvements in or relating to stabilised electric oscillation generators
IPC: H03B5/04
Filed: 1947-05-13
Abstract: 626,786. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., COOPER, A. Y., and McALLAN, J. G. May 13, 1947, No. 12892. [Class 40 (vi)] A resistance-capacitance oscillator has a first thermistor for stabilizing the amplitude of the oscillations and a second thermistor for compensating for changes in amplitude due to changes in ambient temperature of the first thermistor. The Figure shows an oscillator of the type described in Specification 575,395, comprising valves 1 and 2 having a resistance capacitance positive feed-back path 33, 34, 35, 36 and an amplitude stabilizing negative feed-back path through thermistor 3. The oscillator is followed by a two-stage amplifier 4, 5, the output current of which flows through the output transformer 41 and through a resistance network in the cathode circuit of valve 4 producing negative feed-back. This network includes a thermistor 6 operated at low temperature and arranged such that variations in ambient temperature which vary the amplitude at which thermistor stabilizes are compensated by changes in negative feedback due to similar variations in the ambient temperature of thermistor 6. It is suggested that the second thermistor need not be in a feed-back path and that the compensating network may include further thermistors.

Title: Improved method of and apparatus for drying materials
IPC: F26B21/08
Filed: 1931-05-01
Abstract: 378,384. Regulating condition and flow of drying-air ; drying furs &c. SHERMAN, A. E., 58, Dantzic Street, Manchester, JONES, E. R., Jesmond Dene, Shepperton, Middlesex, and LAVENDER, P. C., 3, Grange Road, Southport, Lancashire. May 1, 1931, No. 12918. [Classes 34 (i) and 34 (ii).] The drying of materials in a chamber is controlled by the admission of atmosphere to the circulating air and by subjecting a variable proportion of the circulating air to the action of a desiccating agent. The speed of drying may be gradually increased, commencing slowly. The desiccating element may be byepassed at the commencement, being subsequently brought into action by hand or automatically. In Fig. 1, the air is circulated through a drying-chamber A by a fan E, valves D<1>, D4 controlling respectively admission of air from, and exhaust of air to, the atmosphere. Valves D<2>, D3 control the byepass C of the air-heating and drying element G, H. The air-heater consists of steam pipes G, and may alternatively be situated in the duct B. The air-dryer H comprises a pump M<1>, Fig. 3, feeding sprays Q of glycerine (or calcium chloride solution), the glycerine falling over plates R between which the air passes and being continuously dehydrated by steam pipes N over which it is sprayed at Q<1> by a pump M<2>. The air may be introduced into the chamber A through holes X in a duct T surrounding the chamber. The air may be further heated by steam pipes W, Fig. 1a, in the duct T, the pipes having helical baffle-fins V<1>. The air entering at considerable velocity through the holes X strikes the opposite sides of the chamber and sets up eddying currents. In Fig. 4, furs or skins to be dried are nailed to boards a which are pushed over stationary rollers a<2> and allowed to rest vertically against rods a<1> depending from the roof. The air passes parallel to the surface of the furs. An intermittent air-current may be produced by means of a rotary valve in the inlet to the chamber, assisting in the formation of eddy currents. The cross-sectional area of the inlet or outlet opening may be varied to vary the air-velocity and to produce eddy currents. Materials may be stationary or moving, supported on shelves or trays, or on a conveyer-belt, &c. The material may be acted on by a jigging device such as is described in Specification 378,096.
