Abstract: 1,226,898. Locks. DAIMLER BENZ A.G. 9 July, 1969 [9 July, 1968], No. 34587/69. Heading E2A. In a vehicle all the doors are locked or unlocked by a vacuum or electric system, to correspond with the locking or unlocking of the driver's door, but each of the doors may still be unlocked from inside the vehicle, and in addition, there is a central locking control for all the doors accessible to the driver within the vehicle unlocking from the passenger side. As shown, door locks 1, 2, 3 and 4, boot lock 5 and fuel cap lock 6 are vacuum controlled from the inlet manifold 7 of the vehicle engine. Reversing switch valves 13, 14 distribute this vacuum to either side of motors 22-25 and to a motor 31 of which are side vents to atmosphere. Switch 14 of the front passenger door lock controls a motor 34 of the driver's door so that this may be opened even when access to it is obstructed. Barrel locks 35 have arms 36, 37 which move a rod 39 which operates the switch pistons 42, 43, and the rod 39 is also connected to an operating rod 44 carrying a sill button 45. This rod is connected through a lost-motion link 47 to the diaphragm 53 of the respective motor. Springs 54, 55 give a snap action. Operation of the driver's seat door lock 1 operates switch valve 13 to also operate motors 22, 23, 24 and 25 at the same time. The rear door locks 3, 4 are thus operated together with the passenger seat door lock 2, the boot lock 5 and the petrol cap lock 6. Similarly, unlocking of the passenger seat door 2 by the lock 35 or by the sill-button 45 operates valve switch 15 to apply vacuum to motor 34 to the driver's  door lock 1. Similarly, centralised locking of all the locks may be achieved from the front driver or passenger door. But because of the lost motion by slot 60 in links 59, the rear doors may be unlocked individually. It is described (Fig. 3, not shown) how all locks may be controlled from an over-riding switch valve (15) on the driver's side door, this switch being operated, when necessary, by a brief key-turning of the front-passenger door lock which feeds a motor connected to the passenger lock from a valve switch connected to the passenger lock barrel. In a modification of this arrangement (Fig. 4, not shown), the control from the passenger side is achieved by a reversible electromagnet acting on the driving side lock and energised by the engagement of alternative contacts of an electricswitch linked to the barrel lock on the passenger side.

Abstract: 1,228,720. (cis-1,2-Epoxypropyl) phosphonic acid and salts thereof. MERCK & CO. Inc. 12 May, 1969 [15 May, 1968], No. 23972/69. Heading C2C. A mixture of (+) and (-) enantiomers of {cis-1,2-epoxypropyl) phosphonic acid or a salt of such mixture, e.g. an alkali metal, ammonium, or amine salt, e.g. the monobenzylamine salt, is reacted in solution with a metal salt of an optically active acid or with a metal salt of a mixture of optically active acid enantiomers to produce a metal salt of (cis-1,2-epoxypropyl) phosphonic acid containing a greater proportion of one of the enantiomers and recovering this from the reaction mixture. The metal salt of the optically active acid, whose cation is preferentially transferred to one or other enantiomer of (cts-l,2-epoxypropyl) phosphonic acid, may be an alkali metal salt, an alkaline earth metal salt, a Mg salt, a transition heavy metal metal salt, or a Pb, Al or Sn salt and a wide variety of optically active acids are mentioned. Specified salts used in the examples are calcium (+) gluconate monohydrate, calcium (-) lactate pentahydrate, racemic calcium lactate pentahydrate, cupric ( + ) gluconate monohydrate, magnesium (+ ) lactate trihydrate, calcium ( + ) lactate pentahydrate and an epoxypolyamine ion exchange resin which contains (-) phenylalanine residues on the Cu+ + cycle. Any salt of the epoxy acid isomers which will permit the preferential transfer of the salt-forming cation of the salt of the optically active acid and which will keep the optically active acid and one of the enantiomers soluble in the reaction mixture can be used. Suitable solvents for carrying out the process include water, C 1 -C 5  alkanols, C 1 -C 5  aqueous alkanols, and aprotio solvents, e.g. dimethyl sulphoxide, N,N-dimethylformamide and tetrahydrothiophene dioxide, or mixture of such solvents. Racemio (cis 1,2-epoxypropyl) phosphonic acid is prepared by selective catalytic hydrogenation of 1-propynyl phosphonic acid to form cispropenyl phosphonic acid followed by epoxidation of the latter with H 2 0 2 , a detailed example of each step being given. An example is also given for the conversion of the ammonium salt of the racemic epoxy acid to the monobenzylamine salt by treatment with benzylamine in methanol. (+) Cis (1,2-epoxypropyl) phosphonic acid can be converted to cis propenyl phosphonic acid by heating with potassium thiocyanate in aqueous methanol and can be converted to the (-) enantiomer by splitting the epoxide ring of a salt of the (+) compound by reaction with CF 3 COOH to form [1 -hydroxy-2-(trifluoroacetoxy) propyl]-phosphonate salt, reacting the latter with methane sulphonyl chloride in CH 2 Cl 2  and pyridine to produce [1-(methanesulphonyloxy) - 2- (trifluoroacetoxy) propyl] phosphonate salt and treating the latter in methanol solution with NaOH to produce sodium (-) (cis- 1,2-epoxypropyl) phosphonate.

Abstract: 1,231,443. Photo-electric measurement of moisture content. INDUSTRIAL NUCLEONICS CORP. July 8, 1968 [July 19, 1967], No.32561/68. Heading G1A. Moisture is removed from a travelling web while passing from a first to a second station and the moisture content of the web at the first station is determined by generating signals representative of the mass flow-rate of the web at the first and the second stations, respectively, and of the moisture content at the second station, and using a computer to calculate the moisture content at the first station from these signals. In the described embodiment the web is of paper, produced by the Fourdrinier process as indicated in box 10. The first station C is fitted with a #-ray gauge 47 scanning the web to determine the basis weight (mass per unit area) of the wet web emerging from press 24, before entering a first dryer 26. From this basis weight measurement, the rate of mass flow is determined by multiplication by the width and speed of the web at C, using computer 59, which may be digital, but is preferably analog. A similar gauge 45, at the second station A, where the web emerges from a second dryer 30, measures the basis weight at this station, and a similar computer 53 computes the mass flow at A. A further gauge 49 produces an output representing the actual moisture content of the web at A. (Direct measurement of the moisture content of a very wet web, e.g., at station C, would give inaccurate results). The signals from the computers 59, 53 and gauge 49 are combined in computer 65, preferably analog, according to selected formulae to give an output measure of the moisture content either in lbs water/lbs fibre, or per cent moisture. The gauges 47, 45, 49 may scan the web in synchronism. If the moisture content at A is known to be constant, this moisture factor may be set into computer 65. If differences in speed (or width) between A and C are negligible, one of the gauges measuring speed (or width) may be dispensed with. The output of computer 65 may be in lbs water/lbs basis weight, or other units. The gauges may be located at other "wet" and "dry" positions; e.g., "dry" measurement may be possible after first dryer 26. The signal from computer 59 may be delayed to allow for transport delays. The output of computer 65 may be that recorded or used for controlling headbox consistency, moisture content at the "wet end", etc.
