Title: Improvements relating to crystal detectors for wireless apparatus
IPC: H01L21/48
Filed: 1926-02-23
Abstract: 265,395. Partridges', Ltd., and Mills, H. Feb. 23, 1926. Crystal detectors.-In a crystal detector of the kind employing a pair of crystals means are provided whereby rotation of one of the crystals is prevented unless it is withdrawn from contact with the second crystal. As shown, a crystal e is mounted in a cup c on a stem i slidably mounted in a sleeve j and having a knob k mounted on a sleeve l. The stem i has a head m with a projection n which, when the knob k is pulled to separate the crystals, engages a recess in the sleeve l to enable a rotary movement to be imparted to the crystal e. A light spring. o is provided to ensure the proper action of the clutch when the stem is pulled out. The sleeve j is slotted so as to form a resilient grip for the stem i which, however, is reduced in diameter for a portion of its length in order to permit free rotation after a predetermined amount of withdrawal. The necessary contact pressure between. the crystals is provided by the spring g which forces the crystal d into engagement with a stop f formed on the casing a when the crystal e is withdrawn. In a modification, the stem i may be made rotationally free relatively to the crystal. cup c, means, such as a projection and recess, or roughened face being provided to ensure engagement between the stem and the cup when a pull. is applied to the stem. The Provisional Specification states that the contact pressure between the crystals may be provided by a spring arranged between the stem and the crystal holder actuated by the stem.

Title: Improvements in or relating to fluxes for electric welding processes
IPC: B23K35/362
Filed: 1952-02-27
Abstract: A fine-grained composition, for use in electric welding with covered arcs and which contains substances that react at the welding temperature with strong evolution of heat to form a flux, is obtained by mixing a heterogeneous mass of slag-forming substances with small quantities of sodium or potassium hydroxide, heating the mix to 60-80 DEG  C., agitating, utilizing the heat of reaction of the slag-forming substances to dry the caked mix at a temperature not greater than 100 DEG  C., and screening the product. In an example 30-50 parts of mineral manganese such as pyrolusite or hansmannite, 20-40 parts of silica, 5-10 parts of iron oxide, 10-20 parts of ferrosilicon, 5 parts of fluorite and optionally 5 parts of ferromanganese are mixed with 20 parts of concentrated soda lye and the viscous mass allowed to dry by evaporation due to the heat reaction of the ferrosilicon and manganese ore with the lye.  The resulting mass is granulated and screened.  Manganese and chromium are stated to be advantageously included for incorporation in the welding material.

Title: A process for mechanically longitudinally compressing an advancing length of Flexible Textile Material
IPC: B21D17/00
Filed: 1967-02-03
Abstract: 1,163,177. Finishing fabrics; crimping- apparatus. JOSEPH BANCROFT & SONS CO. 3 Feb., 1967 [4 Feb., 1966], No. 5292/67. Heading D1S. An advancing length of textile material of predetermined thickness is mechanically compacted by driving the material through a passage defined by an overlying material-contacting cover member and an underlying driving means, the material being caused to travel through the passage at a first substantially continuous speed with no substantial change in thickness, and abruptly increasing the thickness of the material by applying a retardant force to decrease the speed of advance thereof, the retardant force being applied to the material by an overlying extension of the cover member having an higher coefficient of friction than that of the material-contacting portion of the cover member in the passage so that the material is forced to accumulation and longitudinally compress in an accumulation cavity immediately adjacent the passage. In one embodiment, Figs. 2 and 4, sheet material 8 which may have been pre-stretched or impregnated with a cured or non-cured resin, passes from a supply onto the surface of a driven roll 7 which may be heated internally. The surface of the roll 7 may be roughened, e.g. formed with knurls 13. The cover member comprises a member 9 which comprises a shoe 14 mounted on a block 16 by arms 15 pivoted at 17. Air cylinders 18, mounted on the block 16 and each provided with an adjustment device 20 to alter the force applied thereby actuate the shoe 14. A flexible steel plate 21 is mounted on the shoe 14 by a holder 22 and extends over the roll 7 to form a first passage therewith. Pressure is applied to the free end portion of the plate 21 by plates 23, 24, preferably steel, removably mounted on the shoe 14 by a clamp 25. A strip 27 of silicone rubber secured under a steel plate 28 is mounted between the plates 23, 24 and the plate 21 to form the accumulations cavity with the roll 7. After compact- 'ing, the material is taken-up by a roll which is driven at a speed less than that of the roll 7 to take-up the material in its compressed state while maintaining the degree of longitudinal compression therein. Subsequently, the material may be permanently set, e.g. by heat setting on a tenter frame. In a modification, Fig. 5, a lip loader 30 applies additional pressure to the plate 28 along the line Q of minimum passage of the material 8 and comprises a plate 31 mounted on the clamp 25 by a bracket 32. A screw 35 applies pressure to the plate 31 which extends across the width of the material. In a further modification, Fig. 6, an auxiliary pressure applying means may be directed against the free edge of the strip 27 so that a second cavity is formed between lines Q and R.

Title: Differential and straight brake equalizer for rotary drawworks
IPC: B66D5/00
Filed: 1930-02-17
Abstract: 349,122. Band brakes. SPALDING, J. D., Crafton, Pennsylvania, and FAULKNER, D. S., 621, South Mariposa Avenue, Los Angeles, both in U.S.A. Feb. 17, 1930, No. 5322. [Class 103 (i).] Brake mechanism for the hoisting drum of rotary draw-works, of the type comprising a pair of spaced brake elements encircled by brake bands each having its live end adjustable for application or release of the brakes, includes a means for slightly loosening the dead end of each band while the live end is being tightened, means for equalizing the force applied to both bands by the brake-actuating mechanism and means for rending inoperative the mechanism for loosening the dead ends of the brake bands. The hoisting drum 1 is provided with a pair of brake drums 6 each surrounded by a brake band 7 connected at its live end 22, in the case of the right-hand band, Fig. 1, to crank-arms 25 secured to a shaft 26 extending through a sleeve-shaft 30 to which the crank-arms 25, Fig. 3, of the left-hand band 7 are secured. The dead end 8 of each band 7 is fixed to a bolt 12 secured at its lower end to a coupling member 14 having a downwardlyextending part 15 containing a hole 16 through which passes the crank portion of a shaft 17. Toothed segments 21 at the opposite ends of the shafts 17 gear with similar segments 33, on the shaft 26 and sleeve 30 respectively. The device is operated by a lever 37 pivoting on the shaft 26 and having a pinion 36 meshing with teeth on brackets 34, 35 on the shaft 26 and sleeve 30 respectively, the movement of the brackets being limited by webs 39 engaging stops 40. The dead ends 8 of the bands 7 may be prevented from moving by the engagement with the straight portions of the shafts 17 of hooks 42 carried by pins 41 on the members 14, thus rigidly connecting the bolts 12 with the straight parts of the shafts 17 so that the cranked parts of the latter rotate freely in the holes 16. In operation, with the hooks 42 released, the handle 37 rotates both the shaft 26 and sleeve 30 causing the crank-arms 25 to tighten the bands 7 and at the same time slightly slacken the dead ends 8 through the respective pinions 21, 33 moving the cranked parts of the shafts 17 to actuate the bolts 12. If the braking force is unequal on either of the bands 7, the shafts 26, 30 will rotate relatively to each other through the pinion 36 to equalize the force on each band, while if the movement of the dead ends 8 is unequal, the toothed segments 21, 33 will be rotated an unequal amount so as to rotate the shafts 26, 30 relative to each other. When the hooks 42 are secured to the shaft 17 the bands are tightened by the crankarms 25, any difference in braking force being equalized as before by the shafts 26, 30. In a modification, all the hooks are secured to a common shaft provided with a handle to permit simultaneous action of all the hooks, which in this case engage shoulders on the members 15. In a further modification the toothed segments 21, 33 are replaced by adjustable crank-links.
