Title: Improvements in precision and like gauges and the manufacture thereof
Filed: 1931-12-28
Abstract: 394,663. Linear-dimension and surface and outline gauges. OSWIN, J., 73, Palmerston Road, Coventry. Dec. 28, 1931, Nos. 35757/31 and 25959/32. [Class 106 (ii).] The gauging members or bushes to receive them are provided with tongues, webs, or keypieces of wedge or dovetail section or with splines, teeth, or serrations, whether they are adjustably or rigidly connected in the gauge body. In the slip gauge shown in Figs. 1 and 2, two anvils e, e are permanently fixed at opposite corners of a quadrilateral body d which may be cast about them. The other pair of anvils e<4>, e<4> are adjustable in a diagonal slot cored in the body and are formed with a ridged or grooved surface which engages with similar surfaces on the sides of the slot. Adjustment is effected by pins p rotatably mounted in the body and having eccentric portions p<1>. Each anvil has two pins p, one in a lateral gap for adjusting the anvil along the slot and one at the end to form a positive lock. This construction is also adapted to a " go " and " no go " calliper gauge, the line of adjustment being inclined to the gap. The same construction of anvils is applied to a form gauge provided with many holes into which the pins p may be placed and the anvils fixed according to the particular work. Anvils arranged to form a hexagon for gauging nuts and bolt heads are similarly adjustable. One of the anvils of a plug gauge for screw threads may be adjusted in like manner and locked by a grooved plate and screw. In the gauge shown in Figs. 14 and 15 the anvil and its adjusting device is carried by a bush or insert t. The locking screw s for the anvil e<4> is received in a spherical nut s<1> which takes a bearing in a second outer spherical member s<2> mounted in a seating in the insert t. The nut s<1> is prevented from axial movement by a collar s<3> screwing into the member s<2>, and is prevented from rotating about the axis of the screw by a pin s<4> in the member s<2> engaging a groove s<5> in the spherical nut. This arrangement leaves the locking screws free to accommodate themselves to the eccentric bushes r, the clamping plates q and the body or insert, and avoids the necessity for accurate machining. In every case where ridges and grooves are provided they may be rounded to engage with line contact only with the flat ridges and grooves in the complementary member. In further forms these bushes or inserts are " cast in" the gauge body to receive the anvils, such bush surfaces lying flush with the gauge gap and strengthening the body at such place. In gauges fitted with roller anvils these may be carried on members inclined to the edge of the gap and fitted with similar adjusting and locking devices. Finally the grooved anvil, eccentric adjusting, and locking devices are applied to gauges where the anvils and their adjusting devices are pivotally mounted in the gauge body.

Title: Production of expanded polyamides
Inventor: BAYERLEIN FRIEDRICH
IPC: C08J9/00
Filed: 1963-09-13
Abstract: Expanded polyamides are produced by heating a mixture of (A) one or more lactams having seven to fourteen ring members, (B) one or more alkaline catalysts, (C) one or more activators and (D) agents which under the prevailing conditions of polymerization volatilize or decompose with the evolution of gas thereby causing the polymerization product to expand, in the absence of substances containing or forming hydroxyl groups to temperatures above the melting point of the lactam and not more than 200 DEG  C. and polymerizing the melt with expansion in the presence of 0.05 to 5% by weight of calcined gypsum with reference to the total weight of the polyamide forming materials.  Lactams which are suitable are those of omega-aminocarboxylic acids such as caprolactam, oenantholactam, capryllactam, caprilactam and laurolactam. C-substituted lactams, e.g. 4-isopropylcaprolactam and lactams having chain-branching or cross-linking effects, e.g. alkylene-bis lactams may also be used. Suitable alkaline catalysts are metals such as sodium, potassium and calcium or compounds of these metals such as potassamide, sodium alcoholates and sodium hydroxide, organometallic compounds and especially alkali lactamates. Specified activators are acyl-lactams, monoisocyanates, polyisocyanates, acid derivatives such as carboxylic acid halides, esters or anhydrides, but particularly substituted ureas, thioureas, guanidines and urethanes.  Examples of these are hexamethylene-1,6-biscarbamidocapryllactam or phenylcarbamidocaprolactam. Suitable expanding agents are aliphatic and cycloaliphatic hydrocarbons such as hexane, octane and cyclohexane, aromatic hydrocarbons such as benzene and toluene and straight-chain and cyclic ethers such as dibutyl ether and dioxane. Liquids having low boiling points, e.g. pentane may be used under pressure. Solid compounds, such as azoisobutyronitrile, benzene sulphonic acid hydrazide and arylsulphazides may also be used.  Dyes, fillers and stabilizers may also be incorporated in the mixture.
