Abstract: 245,017. Wilfley, A. R. July 1, 1925. Leakage - preventing devices; wear, preventing and adjusting for. -A centrifugal pump casing has an intake opening on one side, and a circular opening for the shaft in the other wide enough to form a passage about the shaft which is open while the pump is running, but is closed by the ring 18 while the pump is inoperative. The impeller is secured to the tapered end 31 of the shaft 4 and consists of an imperforate disc 32 with main pumping blades 35 and a set of auxiliary sealing blades 37. The position of the wearing parts may be adjusted by means of the rings R, which move the outer race of the bearing with respect to the frame 3, and also by means of the bolts 48 which pass through the ring 44 and engage the ring 42. When the pump is inoperative the ring 18 is moved by the spring 17 to close the opening round the shaft, but as the pump speeds up the weights 13 of the bell-crank levers 14 fly outwards and their ends cause the ring to move away from the opening. The auxiliary blades prevent liquid from flowing through the unsealed opening.

IPC: H01H37/70
Filed: 1949-06-28
Abstract: 671,058. Thermal switches. SIMPLEX ELECTRIC CO., Ltd. June 21, 1950. [June 28, 1949] No. 17041/49. Class' 38 (v). A thermal switch or cut-out of the kind mounted in the element head or connector of an electric kettle or similar appliance, has its moving contact 29 carried by one end of a spring strip 28 which, when actuated by a thermally-responsive member, moves with a snap-action to the open position where it remains until manually reset. The spring strip 28 is of S-shape, being held under compression by a rectangular frame 30 as described in Specification 640,097. The thermal member 17, 18 is of the differential-expansion, rod-andtube-type and actuates the strip 28 by means of a nut 36 on an operating finger 35 which extends through the strip and is carried by an insulating block 34 on the end of the low-expansion rod 18. Thus when the thermal member is heated to a predetermined temperature, the nut 36 bears on the strip. 28 and causes the strip to reverse its curvature so opening the contacts 29, 33, with a snap-action. The strip having moved from one stable position to another remains in the "open" position as the thermal member cools. The strip 28 is provided with resilient ears or fingers 38 which now just engage the underside of an insulating cover plate 39. Operation of a push button 43 depresses or rocks the. cover plate against the action of springs 42 interposed between the cover and the switch mounting bush 21, and thus causes the spring 28 to resume its initial shape and reclose the contacts 29, 33.

Filed: 1928-06-15
Abstract: 317,575. Dehn, F. B., (Blackinton, G. W.). June 15, 1928. Band or coil. - To ensure the simultaneous engagement of a brake band throughout its length the thickness thereof diminishes from the midpoint towards the ends. In the construction described, the lugs on the band ends are moved towards each other to apply the band to the drum by serew- and-nut or face-cam mechanism. The brake band 20 for engagement with the drum 17, decreases in thickness from the central part 22 towards the ends which are attached to lugs 32, 33 slidably mounted on a rod 35 having right- and left-handed threaded parts engaged by nuts 40, 41. Each lug 32, 33 is grooved to receive the rod 35 and has a finger 50 which rests upon a roller 47 on the other lug whereby pivotal movement of the lugs about the pins 30, 31 is prevented. The nuts 40, 41 are square and are disposed between projections 38, 39 on the lugs 32, 33 to prevent relative, angular movement of these parts. The rod 35 is rotated by a lever 60 to contract and expand the band. The rod and lever are provided with interengaging toothed discs 58, 59 whereby relative angular adjustment may be obtained. The brake is shown arranged on the transmission shaft of a motor vehicle, the bearings 53 for the rod 35 projecting from a bracket. 26 bolted to the gear box. A pin 24 on the brake band and extending through a slot in a lug on the bracket 26 prevents lateral displacement of the central part of the band. As shown in Fig. 8, the operating means comprises a cam face 72 on the end of the rod 66 in contact with a corresponding face on a fixed member 68. The lugs 32<a>, 33<a> are urged apart by a spring 78. The varying thickness of the brake band may instead be obtained by securing a reinforcing strip to the middle part of a metallic band of uniform thickness.

Patent GB-351999-A (GB)
Title: Improvements in or relating to textile materials
Filed: 1929-12-21
Abstract: Crape effects are produced on fabrics comprising highly twisted crape threads and more particularly on fabrics comprising crape threads made of or containing cotton or other natural cellulose fibres, or artificial filaments such as regenerated cellulose or cellulose acetate or other cellulose esters or ethers, by treating the threads before or after twisting to a high degree with a substance adapted to cause swelling of the material of the threads.  Examples of such swelling agents are ammonium, calcium, or other thiocyanates, or zinc halides, sodium iodide, and calcium chloride or nitrate, acetic, lactic, aromatic-sulphonic, or other organic acids, methyl, ethyl, or other alcohols, acetones methyl-ethyl-ketone, methyl acetate, ethyl lactate, and amines such as aniline, any of which are suitable for cellulose esters or ethers while the inorganic compounds are more suitable for cotton or regenerated cellulosic artificial silk.  On scouring fabrics containing threads so treated craping is effected. As an example, a fabric comprising threads of cellulose acetate which have been treated with absolute ethyl alcohol or with acetic acid applied in a benzene solution is subjected to the action of water whereupon craping is effected.  The swelling agents may be incorporated in the filaments or fibres during processes of their manufacture, suitable swelling agents for incorporation being calcium chloride or nitrate, zinc chloride, sodium iodide and ammonium, calcium or other thiocyanate, which agents may be applied in acetone or other suitable solutions.  Where the swelling agents have too strong a solvent action on the materials treated, their use with suitable diluents either as vapour, liquid, or gas is preferred. Suitable diluents are aliphatic or aromatic hydrocarbons such as petroleum ether, benzene, or toluene.  Soaps, wetting agents, salts, acids, or other substances which modify the craping action of the water may be added thereto, and the craping treatment may be combined with the dyeing of the fabric.  Softening of the filaments should be avoided.  The conditions necessary in the process described in Specification 348,589, for treating a sized craped thread or fabric should be observed, and with that process the present process may be combined.  The highly twisted crape threads may be used either as warp or weft.  In an example, cellulose acetate yarn is immersed in commercial dichlorethylene, twisted to form a crape thread which is then woven as a warp, two picks of left-hand twist alternating with two picks of right-hand twist.  The fabric so obtained, on scouring in an aqueous bath, exhibits crape effects. Specifications 224,642 and 226,256, [both in Class 142 (iv), Woven fabrics &c.], are also referred to.
