Abstract: 1,052,048. Ski bindings. H. MARKER. Jan. 28, 1964 [Feb. 11, 1963], No. 3611/64. Heading A6D. A safety ski binding comprises a plastics or metallic block 4 rotatably mounted on a pin 3 fixed to a base plate 1 secured to the ski, the block 4 being normally held against rotation by a spring-urged detent 17 co-operating either with a recess in the base plate 1, or preferably with a recess in a plastics or metallic boot-engaging member 12 screwed on to a pin 11 rotatable in a bore of the block 4. The detent 17 its spring 18, and a screw threaded bolt 19 for adjusting the spring are also housed in a further bore provided in the block 4, the bolt being displaceable axially by means of a nut 20, but being held against rotation by a projection 25 engaging a slot 26 in the block, the projection moving over a scale to give an indication of the compression of the spring and therefore the torque needed to release the binding. The block 4 is vertically adjustable on the pin 3, a further spring-urged detent 7 preventing movement of the block relative to the pin during normal use of the binding, but in the event of the skiers falling, the member 12 is rotated about the pin 11 to one side, and the block 4 rotates about the pin 3 to the other side.

An electric circuit for an ergometer having a generator driven, by the person to be examined, by means of mechanical transmission wherein friction losses occur and which is connected to a circuit for regulating the power supplied to a load resistor, is characterized in that the regulating circuit comprises an arrangement which reduces the electric power received by the load resister by an amount which is substantially proportional to the rotary speed of the generator and to the friction losses. Preferably the regulating circuit keeps constant the sum of the voltage drop across the loading resister and a compensating voltage which is substantially proportional to the square root of the speed. The invention is illustrated with referenec to a circuit arrangement wherein the regulating circuit regulates the field current of the generator.

Abstract: 1,264,269. Treatment of polyacrylonitrile fibres. MONSANTO CO. 23 March, 1970 [24 March, 1969], No. 13841/70. Heading B5B. [Also in Division C1] A process for the production of fireproof fibres involves a two stage treatment in which acrylonitrile polymer or copolymer fibres are heated while under tension: (1) in an atmosphere containing oxygen and bromine, suitably an airbromine mixture, at a temperature below 250 C., preferably between 180 and 230 C., for a time sufficient to allow the desired degree of sheath formation; and (2) in the presence of an oxygen containing atmosphere, preferably air and in the substantial absence of bromine, at a temperature above 250 C., suitably between 270 and 320 C., for a time sufficient to allow complete permeation of oxygen throughout the fibres.  The desired degree of sheath formation is that obtained by heating the fibres for a time sufficient to allow the surfaces of the fibres to be converted to a sheath which is permeable to oxygen, non-fusing and strong enough to support the fibres during further processing at higher temperatures. This time must, however, be insufficient to allow complete permeation of oxygen to the cores of the fibres and is suitably less than one hour, preferably less than 30 minutes. Under optimum conditions the concentration of bromine in the first stage is such that after the whole process is complete the resultant fibres contain at least 1% by weight of bromine. Throughout the treatment, the second stage of which may take up to two hours, the fibres are maintained under tension, this tension preferably being adequate to allow not more than 20% shrinkage of the fibres. Fibres so treated are generally fireproof, flexible, strong and dimensionally stable at high temperatures and are particularly suitable for graphitization (for details of the graphitization procedure see Division C1).

Abstract: 1,265,679. Parametric optical oscillators. WESTERN ELECTRIC CO. Inc. 8 May, 1969 [13 May, 1968], No. 23531/69. Heading H3B. [Also in Division H1] In an optical parametric oscillator comprising an optically non-linear crystal to which a pumping radiation is applied to generate first (idler) and second (signal) frequencies, the idler frequency is made to be resonant: whereas the signal frequency is non-resonant. Pumping radiation from c.w. Argon ion laser 12 is applied to non-linear crystal 11 situated in the laser (pump) cavity defined by multiple dielectric reflector 15 and reflective coatings 16, 17 on prism 18, to provide mode selection. The crystal 11 is also situated in an idler resonator 21, 22 and reflectors 15, 21 and 22 are such that reflector 15 is highly reflecting for-pump radiation and highly transmitting for signal and idler radiation, reflector 21 is highly reflecting for idler radiation and highly transmitting for pump radiation and reflector 22 is highly transmitting for signal radiation andhighly reflecting for idler radiation. Thus, the signal radiation is not resonant in the parametric oscillator cavity 21, 22 and the phases of the signal and idler are always such that the flow of energy is only from the pump to signal and idler. Rough tuning of the signal and idler: frequencies is by temperature controlling crystal 11, i.e. changing the path length. Since the temperature tuning alsochanges the optical path length of the pump radiation an electrooptical modulator 27 is provided which maintains the pump path length constant. In order to maintain the pump radiation at a specified single longitudinal mode, a feedback control system can be used which derives a signal from frequency comparator 31 and modifies the voltage to compensator 27. Fine tuning of the idler resonator is provided by moving reflector 22 by piezo-electric crystal 23. If fine tuning is not employed, the pump source may be multimode in which case prism 20 is replaced by a simple mirror. The arrangement of Fig. 1 may be adapted for multiple-axial-mode operation of the pumping laser and mode locked operation of the parametric oscillator, Fig. 2 (not shown). Mode locking is achieved by inserting an inhomogeneously saturating dye cell and a mode locking electro-optical modulator in the idler cavity outside the pump cavity. In an alternative embodiment, Fig. 3 (not shown), a pulse from a bleachable dye Q-switched single longitudinal and transverse mode giant pulse ruby laser is passed through an optical isolator to a parametric oscillator comprising a non-linear crystal in an idler cavity, one of the mirrors of which is highly transmitting for the signal radiation. Course tuning of the oscillator is by rotating the non-linear crystal, controlling its. temperature, applying: an. electric field or by pressure. The non-resonant signal may be obtained by inserting an absorption device in the idler cavity.
