Title: Toe iron for safety ski bindings which is suitable for downhill and cross-country skiing
IPC: A63C9/085
Filed: 1967-08-25
Abstract: A toe piece for safety ski bindings suitable for downhill and cross country skiing comprises a fixed member I adapted to be secured to the ski forwardly of the ski boot, a pivot pin 5 mounted on the fixed member for transverse displacement from the longitudinal axis of the ski, the pin 5 being perpendicular to the surface of the ski, a spring 11 operatively connected between the fixed member and the pin to resist relative movement between the pin and the fixed member, and a pair of rearwardly extending sole-holding members 6, 7 for receiving therebetween and engaging the ski boot, the sole-holding members being mounted on the pin and being held against pivotal movement when the pin is in the normal position relative to the fixed member but being free to pivot thereabout when the pin is displaced laterally a predetermined distance to either side of the normal position against the bias of the spring. The spring may be a compression or helical coil spring or gas spring and is mounted in a transverse recess 10 in the fixed member each end of the spring engaging a fixed abutment 13. The pivot pin and sole-holding members are mounted on a carrier 4 which is slidably retained in the fixed member e.g. by guide roller 19 in transverse groove 18, the carrier being further provided with guide rollers 20 and 21 operating on cam 22 and extending members 14, 15 engaging each end of the spring. Transverse displacement of the pin causes compression of the spring tending to return the pin to the normal position but when displacement exceeds a predetermined distance one of the rollers 20 or 21 moves free of the cam 22 thereby enabling pivotal movement of the respective sole holder about the pin with release of the boot from the binding.

Patent ES-363640-A1 (ES)
Title: Headlamp adjusting systems
IPC: B60Q1/10
Filed: 1969-02-07
Abstract: A road vehicle headlamp adjusting system comprises a member 25 adjusting the headlamp 20 under the influence of piston 22 acting in a cylinder 21 according to the pressure of hydraulic fluid in that cylinder, the fluid pressure being controlled by a further piston 14, in a sensing unit, secured to a rear suspension member of the vehicle and sliding in a cylinder 13. Cylinder 13 and cylinder 21 are interconnected by a pipe 17 via a solenoid operated valve 18. When the vehicle ignition is off, the solenoid causes valve 18 to be open and any fluid displaced from or drawn into cylinder 13 due to the rear of the vehicle body moving relative to the wheels, as during loading or unloading, causes movement of piston 22, member 25 and thus of the headlamp. Spring loaded plunger 26 keeps member 25 in contact with piston 22. To prevent adjustment of the lamps due to normal vehicle suspension movements during travelling, the solenoid operates when the vehicle ignition is on to close valve 18 and isolate the cylinders. Changes in hydraulic fluid pressure in cylinder 13 are then taken up by an auxiliary cylinder 15 in which a spring loaded piston 23 operates. In a modification of this embodiment the plunger 26 may be replaced by a further piston similar to piston 22 but connected to a second sensing unit connected to the front vehicle suspension member. In this modification the two pistons operating the lamp may be interconnected when one of the control valves will not be required. In a further embodiment, Fig. 2, not shown, diaphragms are used instead of pistons to apply and respond to pressure changes in the hydraulic fluid. The place of valve 18 is taken by a device having a diaphragm operated according to the engine manifold pressure to squeeze the flexible pipe in which the hydraulic fluid flows and cut the flow when the engine is running and the manifold pressure is low, but to release it when the engine is stopped and the pressure is atmospheric. A bleeder valve operated by a solenoid controlled by switches on the vehicle doors ensures that the pipe is released when those doors are open for loading or unloading. As in the first embodiment, if a sensing unit is connected to the front as well as the back suspension member, no device for stopping the hydraulic fluid flow is required.

Title: Process for separating enantiomers of (cis-1,2-epoxypropyl)phosphonic acid
IPC: C07F9/655
Filed: 1969-05-12
Abstract: 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.

Title: Plural operating mode television receivers
IPC: H04N5/445
Filed: 1970-06-11
Abstract: A television receiver can be switched to receive video signals, e.g. recorded on tape, and is also provided with a video output for the purposes of recording it is characterized in that the automatic gain control (A.G.C.) is operative not only when receiving radio signals, but also in the reception of video signals, to stabilize the D.C. level. A colour television receiver includes ganged switches 74, 75, 80, 81, 82, 83, 84 which in the position shown are set for the reception of video signals, and in the reverse position for reception of radio signals. The receiver comprises a pentode video amplifier 56, the anode of which is coupled to chrominance processing circuits 70, and via a frequencycorrecting network to a triode luminance amplifier 57. The cathode of triode 57 feeds video signals to switch arm 74, the anode feeding sync. separator circuit 61 and the grid of an A.G.C. gate valve 60. The valve 60 is pulsed conductive by line frequency pulses applied to its anode and derived over capacitor 63 from deflection circuits 64, to produce a D.C. potential which is smoothed and applied over resistors 108, 109, 110 to control the gain of I.F. amplifier 51. Video signals to be reproduced are applied from terminal 86, via level-setting control 87 to an amplifier comprising transistors 89, 96, 105, the output of which is fed via switch 83 into the cathode of video amplifier 56: when operating in this manner, switch 84 places a positive bias, via resistor 114, on the base of the transistor 112 which is also coupled via diode 111 and line d to the output of A.G.C. valve 60. Transistor 112 thereby obtains an opposing signal-dependent bias which stabilizes the D.C. level in amplifier 89, 96, 105 which is directcoupled, and in which the base bias of transistor 89 is derived over resistor 92, through which the collector current of transistor 89 flows. Switch 84 also varies the D.C. bias on the grid of valve 56 to allow for the additional positive cathode bias when operating on video input. Switches 74, 75 apply the luminance output from the anode of amplifier 57 to the input of third video amplifier 77, via a delay line 76 additional delay is introduced by means of a second delay line 120 when receiving radio signals, to compensate for the effect of the R.F. and I.F. circuits. For the purpose of video recording an output is provided on terminal 150, being derived from the cathode of triode amplifier 57 via an amplifier comprising transistors 125, 139, 140 and 145 this amplifier includes frequency compensating circuits and also a delay line 138 which compensates for delay of the chrominance components in the R.F. and I.F. circuits. When receiving video signals, a faster capture for synchronization of the line oscillator is necessary and this is effected by switching filter timeconstants in the line oscillator circuits (Fig. 4, not shown) the switching is effected by switch 82.
