Title: Improvements in and relating to glazing roofs
IPC: E04D3/08
Filed: 1931-07-20
Abstract: 373,475. Glazing roofs. MORRIS & COLPUS, Ltd., 9A, Woodward Street, Wellington, New Zealand. July 20, 1931, No. 20700. Convention date, Sept. 30, 1930. [Class 20 (iii).] Relates to fittings employed for joining together the sections of a glazing bar. According to the invention, the fitting comprises a doubled opentopped portion 1, Fig. 5, a twin-cylinder portion 4, and a dividing wall 3. The upper section 8 of the glazing bar, Figs. 1 and 4, rests with its lower end bearing against the wall 3 and with its rolled-over portions resting in the sockets 1a of the fitting. The cylindrical fittings 4 are enclosed by the doubled-over portions 7a of the lower section 7 of the bar, the upper end of which also bears against the wall 3. A centrally disposed wall 2 and an extension 2b thereof extend respectively between the ridges of the sections 8a, 7a. The glass panes 9, 9a rest on the rolled-over portions 8a, 7a, and are secured in position by overlapping cap members 10. These members are connected to the bar and to one another by nuts 12 which screw on to studs 11 carried by the glazing bar. The wall 3 extends above the upper surfaces of the cylinders 4 by a distance equal to the combined thickness of the glass and the metal of the glazing bar. This arrangement enables the panes 9, 9a to be arranged in overlapping relationship. The fitting is provided with lugs 6 by which it can be secured to purlins or the like. The portions 4 are made hollow to permit the escape of any water collecting in the rolled-over bar sections. Specification 323,842, [Class 20 (iii), Doors &c.], is referred to.

Abstract: 624,179. Transmitting mechanical power. DESMOULINS, E. H., and THIRIET, M. July 11, 1946, No. 20713. Convention date, July 11, 1945. [Class 38 (iv)] In an electromechanical power unit for a vehicle, a first element of a differential gear is driven by the prime-mover, a second element is connected to a dynamo-electric machine electrically connected to another dynamo-electric machine driven by the prime-mover, and the third element of the differential is mechanically connected to the driving wheels of the vehicle, the two dynamo-electric machines each having both series and separate excitation windings and means being provided to vary the magnitudes of the separate excitation currents and, in the case of the second machine, the direction of the excitation current also. As shown in Fig. 2, the axles 30 of a self-propelled vehicle are driven from the satelite carrier 10d of a differential gear 7-9, the planet wheel 7 being driven by the prime-mover 1 which also rotates a dynamo-electric machine 3a. Planet wheel 8 is connected to the shaft of a second dynamo-electric machine 3b, the armature of which is connected in opposition to that of the machine 3a. Both machines have series field windings 14a, 14b, and windings 15a, 15b, which are variably and separately excited by an engine-driven source 5. The controller 16 for winding 15a permits reversal of excitation of machine 3a. A " forward " and " reverse " clutch 25 is engageable with either of pinions 19, 23, which are oppositely rotated by the satelite carrier through gears 18, 20, 21. A solid mechanical drive is obtained by locking together the members of the differential and opening the armature and field circuits of machines 3a, 3b. The clutch may be dispensed with and the reverse drive obtained by de-excitation of machine 3b. Specification 21173/03, [Class 38], is referred to.

Abstract: 476,068. Axminster carpet looms &c. TOMKINSONS, Ltd., and CARTWRIGHT, G. H. July 28, 1936, No. 20838. [Class 142 (ii)] The tuft yarns b are inserted by a single tube frame a and are supplied direct thereto from bobbins on one or more stationary creel frames. The yarns pass over a main wire-carded or like, braked guide roller c having a top pressure roller d, thence through a spacing comb e over a guide roller f, and over the front of a fixed rubber-faced flat bar g through the spacing and threading apertures a<1> to the tube frame. Suspended levers h are rocked to the left against the action of springs by adjustable hooked connecting rods operated from the crankshaft h. A clamping-bar o on spring-controlled rods n on the levers h first grips the yarns against the bar g, after which, as the levers h move further to the left, a roller m carried thereby forces the clamped yarns rearwardly (to the left) whereby the desired length thereof is drawn from the creel. The slack is taken up on the next insertion of the tube frame. Adjustable stops r limit the forward motion of the levers h.

Title: Improvements in the production of a jelly base containing pectin
IPC: C08L5/06
Filed: 1921-08-08
Abstract: A mixture of pectous substances for a jelly base is produced by treating a material containing pectose with a solution of pectase derived from a non-acid vegetable, such as carrots.  Acid present is removed by washing, or neutralized with calcium carbonate, and the pectous materials may be precipitated by alcohol and dried by a blowing process.  The treatment of apples according to the invention is described in full, the resulting product being a mixture of pectin calcium pectate, pectose and a small amount of pectase.  A mixture of pectic acid (which is derived from the calcium pectate) and pectin, gives a better jelly than either separately.

Abstract: 1,273,727. Winding and reeling. REPUBLIC STEEL CORP. 4 May, 1970 [12 May, 1969], No. 21322/70. Heading B3E. A method of coiling elongated metal tubing, rod or strip comprises bending a continuous length at a varying bending radius until one or more convolutions have been completed and next bending a length continuous with the first length at a constant bending radius. In making the coil a steel tube is bent to produce outer and inner spiral convolutions 20a, 20b, 20c and 20d (Fig. 1). The bending radius is held constant during making convolution 20d then at the end of convolution 20d a second layer either above or below the first layer is started e.g. 22d (Fig. 7) at constant bending radius then further convolutions 22c, 22b, 22a at increasing bending radius. After 22a is completed the bending radius is held constant and a third layer 23a, 23b, 23c, 23d is similarly formed. The process is continued until a coil of the desired size is formed. Apparatus for carrying out the method comprises a support roller 85 under which the tube, bent at the bending station 21, passes after which the tubing passes over support rollers 89, 90, 86, 87 and 88 and then over roller 85. The bending station comprises a base plate 28 on which is a pivoted plate 29 adjusted by a bolt 30 to accommodate different diameters of tubing. Guide rolls 34, 35 and 36, 37 are also mounted on the base plate. The pivot shaft 40 of the plate 29 is extended to carry an arm 42 provided with a bending roller 49 the shaft 44 of which also carries an arm 51 and cam follower 52 which engages an hydraulically actuated cam 53 mounted on the plate 29. The cam is controlled by limit switches 62, 63 to vary the bending radius by movements of the roller 49. The apparatus is controlled by electrohydraulic circuits depicted schematically in Figs. 9 and 10 (not shown). An alternative supporting mechanism (Fig. 8) comprises a coil basket 93 having lockable coasters 94 resting on a circular plate 95 supported by roller bearings 94 on a shaft 98 of an hydraulic cylinder 99 let into the ground. A depression 100 is left to accommodate the plate 95 so that the basket with the completed coil can be rolled away.
