Filed: 1976-08-04
Abstract: 1518588 Embossing BIGELOW-SANDFORD Inc 4 Aug 1976 32575/76 Heading B6J [Also in Division D1] A polyacrylonitrile or modified polyacrylonitrile pile fabric is embossed by contacting selected areas of said fabric with a composition containing ethylene carbonate, which composition shrinks said areas, the ethylene carbonate being applied in an amount of at least 25% by weight of the said selected areas of the fabric. The fabric may be simultaneously printed and embossed by incorporating a cationic dye, preferably an astrazon dispersed dye, in the ethylene carbonate composition. After treatment with the composition, the fabric is steamed and then washed or rinsed.

In the injection moulding of beakers or sleeveshaped containers, a core member 1 (Fig. 3) and mould 3 are positively located with respect to each other by one or more locating members 4<SP>11</SP> during an initial moulding stage during which the maximum injection pressure is reached, and the locating members are subsequently retracted while moulding is completed at a lower pressure. In Fig. 3 the core 1 is located by spaced ribs 4<SP>11</SP> on an insert 9 which is moved in the direction of arrow 10 for the second moulding stage. In Fig. 4 (not shown) the ribs (4) are on a central movable portion (12) of the core (1). The portion (12) is formed with cooling channels. In Fig. 5 (not shown) the core is located by centring pins (40) slidably mounted in the core (1) or mould (3). In Fig. 6 (not shown) the centring pins (40<SP>1</SP>) project radially from the side of the core or mould. The pins (40) and (40<SP>1</SP>) may be operated hydraulically or mechanically. A conical seating (14) may be provided for the core (1) in a base-plate (15), Fig. 7 (not shown). In Fig. 8 a core 21 is securely held by means of a slidable member 24 engageable with a recess 25 in a head part 22a of a mould 22. A doubleacting piston 26 enables the member 24 to be moved hydraulically. Material is injected through a quadruple injection nozzle 27 having a heat-conducting core 28.

Title: Method of and apparatus for making a multiple layer unit of powdered material suitable for use in the manufacture of friction discs
IPC: B22F7/02
Filed: 1946-11-05
Abstract: 629,291. Moulding friction discs. BURGESS, A. F. (Wellman Co., S. K.). Nov. 5, 1946, No. 32855. [Class 87 (ii)] [Also in Group XXXIV] Friction discs, e.g., for brakes, are made of multiple layers of powdered material (see Group XXXIV) by a method in which a layer of material is simultaneously spread and compressed, after which a further layer is spread and compressed upon the first without disturbing the disposition of the material in it. The disc may be formed in a rotatable annular mould 26 into which depend a spreader blade 39 and, behind it, a feed chute 49. The amount of material entering the chute from a hopper 48 is controlled by manually-rotatable fluted cylinder 52, Fig. 5, mounted in the hopper. Both the feeding means and the spreader blade are connected to a holder 38 mounted between pairs of adjustable antifriction bearings 37 and vertically adjustable by means of a nut 60 engaging the upper screw-threaded portion of the holder. The spreader blade (Fig. 7), has a leading face 67 inclined at an angle N, e.g. 9 degrees, to the vertical and its bottom surface divided into two faces 61, 62 at an angle B, e.g. 2 degrees, to each other. The leading face is arranged at a slight angle, e.g. 3¢ degrees, to the radius of the mould to counteract centrifugal force on the powder. In operation, the rate of feed and the rate of elevation of the blade are adjusted to maintain a small pile of powder in front of the blade. A layer of metal powder followed by a layer of friction powder is spread, then a separating disc is placed in position and two more layers spread, and so on. When the mould is full of such double-layer units spaced by separating discs, the stack of units is taken from the mould and subjected to considerable pressure to form briquettes. The separators are then removed.

The diamines, diacids or di-isocyanates may also be used in making polyamides, polyureas or polyurethanes.ALSO:Bis-halo-methyl aromatic compounds are produced by the reaction between a benzene hydrocarbon with 2 moles. of a halomethylalkyl ether in presence of 2 moles. of an acylating agent to fix the alcohol by-product formed.  In examples, durene is treated with chloromethyl ethyl ether with and without (for comparison) acetic anhydride, and in various solvents with Friedel-Craft catalysts (for comparison), and gives bis-chloromethyl and monochloromethyldurene.  The bis-product can be converted by usual methods into a number of useful derivatives including: bis-hydroxymethyl durene, bis-acetoxymethyl durene, tetramethylterephthalic acid and bis-cyanomethyl durene.

Title: Distance measuring with the aid of sound waves
IPC: G01S15/10
Filed: 1922-12-12
Abstract: 190,481. Atlas-Werke Akt.-Ges. Dec. 16, 1921, [Convention date]. Determining distances acoustically.-Comprises means -for measuring distances or depths by timing the travel of a sound or echo. The apparatus is particularly applicable to short distances, and employs an electric circuit which includes contacts adapted to be opened or closed on the emission and arrival of sounds emitted in regular succession, the time of travel being continuously indicated by an electrical measuring instrument included in the circuit. The soundproducer S, Fig. 1, is caused to emit regular pulses of sound by intermittent closure of a rotary switch R<2> driven by the motor M, the frequency being observed by a frequency meter F<2>. At theemission of each pulse, the magnet EM is weakened momentarily and releases the armature F so as to close the switch K<2>, but on arrival of the sound at the microphone E the magnet EM is momentarily strengthened so that it attracts its armature F again. The cycle of operations is repeated at each pulse, and the quantity of electricity which passes through the instrument A<1> during each cycle depends on the time of travel of the sound. The instrument A<1> being dead-beat, a continuous reading is afforded by it of the distance a, and so the depth of the sea where the echo method is used. The battery B<3> may be replaced by a source of alternating current, an A.C. instrument A<2 >being inductively coupled as shown. The various devices may be modified for work with either normally open or normally closed circuits. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an embodiment of the invention in which an electric sound producer is operated simultaneously with the closure of an electric measuring circuit, which, on the arrival of the sound at the end of its course, is broken again by the action of a relay controlled by a microphone. The quantity of electricity which has meanwhile passed round the circuit is determined and affords a measure, of the time of travel. Alternatively the sound from a soundproducer S, Fig. 2 (Cancelled), on arriving at the microphone E<1>, causes a momentary strengthening of the permanent magnet M<1> and so breaks at K<1> one branch of a bridge which is so balanced that the instrument A normally takes no current. Current flows through A, however, from the opening of the switch K<1> until the opening of the switch K<2> on arrival of the sound at the microphone E<2> over the path E<1>PE<2>, and the time of travel is given, as before, by the quantity of electricity which has passed. Screens Sch<1> and Sch<2> protect the microphones from the reflected and direct sounds respectively. In a further modification measurement is made of the charge lost by a condenser during the time of travel of the sound. This subject-matter does not appear in the Specification as accepted.
