Abstract: 1,231,973. Automatic exchange systems. SIEMENS A.G. 28 March, 1969 [29 March, 1968], No. 16352/69. Addition to 1,058,893. Heading H4K. The " short circuit " or " short cut " connection used in the switching network described in the parent Specification is made by operating two relays in the same column of the co-ordinate array. To set up a required connection all the relays arranged in the intersecting row and column are reset and the particular relay set up. This procedure is then repeated for the second connection except that the column relays are not reset. In operation marker contacts Z1 and 2S2 are operated if the respective row and column are not busy and the pairs of contacts 13, 14; 23, 24; 33, 34 and 43, 44 operated to reset the row, the column, the relay itself and finally to set the relay respectively. In order to set up a second relay in column 2, the respective line marker contact Zn (Z1 is now open) is operated and the row relays reset by closing contacts 13, 14. Contacts 23, 24 are not operated and the sequence then continues as before with the closure of contacts 33, 34 and 43, 44 to set up relay Kn2. The contacts 23, 24 are prevented from operating by use of the controller shown in Fig. 5 where a pulse emanating from Pr1 can be diverted to Pr3 when an inhibiting signal is applied at KW. In a modification of the system, Fig. 4 (not shown) each relay operating coil may be connected in series with a varistor and only a single column line connection is required. Specification 1,227,056 shows a similar arrangement for operating relay switches.

Lactam compositions capable of being converted to polyamide foams are made by heating a lactam with a catalyst for lactam polymerization which is insoluble in the lactam at the melting temperature of the lactam, at such a temperature that the catalyst dissolves without the lactam polymerizing, then precipitating the catalyst by cooling with stirring to a temperature up to 15‹ C. above the melting point of the lactam, adding activators for lactam polymerization, blowing agents and pore regulators to the lactam at this temperature and then flaking off the melt thus obtained over a cooling roller. The lactam may be caprolactam, and the catalyst may be an alkali metal or alkaline earth metal formate. An isocyanate or adduct thereof, e.g. hexamethylene diisocyanate may serve as both an activator and a blowing agent. The composition may contain silica gel or tale as crystallization nuclei and a polysiloxane-oxyalkylene block copolymer as pore regular. A foam may be made by heating the composition.

[Also in Division C1] A metallizing composition, particularly for coating glass windshields, consists of from 40-95% by weight of a noble metal, from 2-20% by weight of an inorganic binder particularly of glass and an alkali metal salt or alkaline earth metal salt or mixtures thereof, the salt being present in an amount which yields upon joining from 0.1 to 10% of the ion-based on the weight on the metallizing composition. Silver is the preferred metal but platinum and/or palladium or mixtures with silver may be used. The preferred salt is sodium carbonate or sodium oxalate or a mixture but lithium carbonate and the following sodium salts are suggested: bicarbonate, chloride, sulphate, borate, silicate, plumbate or bismuthate. A glass frit suggested is, by weight per centages, PbO 65; SiO 2 34; AL 2 O 3 1. BiO 2  may be present in the binder or in the glass frit itself. A liquid vehicle for the composition may be water or a higher alcohol or ester, a terpere or a solution of a resin. The salt ion appears to enter the glass substrate in preference to the noble metal and thereby prevents discolouration.

Abstract: 1296493 Optical isomers of arylacetic acids SYNTEX CORP 24 Feb 1970 [24 March 1969] 8909/70 Headings C2C and C2U An α-substituted d- or l-arylacetic acid having at the asymmetric α-carbon, hydrogen, a non- aromatic substituent other than hydrogen and an aryl group, the α-carbon atom being bound to an aromatic ring of the aryl group is racemized by maintaining a first inert organic racemizing solvent solution of a salt of a predominantly said d- or l-arylacetic acid and an optically active nitrogeneous base at a racemizing temperature until racemization occurs, forming a solution of a salt of racemized arylacetic acid and the nitrogeneous base. This solution may be subacted to resolution by crystallizing the racemized salt from a second crystallization solvent to yield crystals of the salt containing a greater proportion of d- or l-arylacetic acid salt than the solution from which it is is crystallized, leaving a solution of predominantly l- or d-arylacetic acid salt. This solution may be racemized in a second racemizing solvent by maintaining the solution at a racemizing temperature until racemization occurs, forming a solution of a salt of racemized arylacetic acid and nitrogenous base. The racemized arylacetic acid salt may be further resolved by crystallizing it from a third crystallization solvent to yield crystals of a salt containing a greater proportion of d- or l-arylacetic acid salt than the solution from which it is crystallized. The purified salt of d- or l-arylacetic acid and nitrogenous base may then be acidified and the free acid separated from the resulting mixture. Specified acids include naphthalene acetic acids of the formula wherein R is CH 3 , C 2 H 5 , CHF 2 , F or Cl and R<SP>1</SP> and R<SP>11</SP> (at position 1, 4, 5, 7 or 8) are H, OH and hydrolysable esters thereof, F, Cl, C 1 -C 6  alkyl, alkoxy or thioether groups.

Examples are given which illustrate this process. The initial salt of predominantly d- or larylacetic and optically active nitrogenous base in the first inert organic racemizing solvent solution may be prepared by crystallizing crystals of predominantly the opposite l- or d-arylacetic acid salt from a racemic mixture of l- and d-acids in a first crystallization solvent.

In normal service application a pedal 32 operates a valve plunger 25 thereby communicating wheel cylinders 14 with an accumulator 22 pressurized by a pump 19 driven by the vehicle engine, a feedback line 20 being provided in the conduit 27 to the wheel cylinders for providing "feel". Wedge expanders 15 are normally kept inoperative by pressurizing chamber 35 of spring applied fluid pressure released actuators 17 with liquid from pump 19 and accumulator 22 which passes to an inlet 65 of valve 34 by way of conduit 29. The pressure is transmitted by way of port 61 to an accumulator 36 and also moves a valve plunger 54 to open a radial port 63 and close a radial port 62 allowing liquid to pass by way of a passage 73, port 73, a groove 69 and a port 71 in a further valve plunger 68, and conduit 30 to chambers 35. To initiate a parking application a handle 38 is pivoted upwardly moving plunger 68 and bringing port 72 out of register with groove 69 causing the latter to communicate with a drain port 76 connected by a groove 77 to a port 65 leading by way of a conduit 37 to a reservoir 21. Liquid is thereby released from chambers 35 and the wedge expander applied by springs 18. If the pressure for the system fails a non-return valve 67 prevents loss of pressure in accumulator 36. If the brakes are then applied several times by operation of lever 38 pressure in the accumulator 36 is dissipated until a spring 58 overcomes that pressure and moves valve plunger 54 to connect chambers 35 to drain through port 62.
