Abstract: 957,557. Pneumatic actuation of switches. BENDIX CORPORATION. Oct. 22, 1962, No. 39916/62. Heading H2B. A pressure responsive switching device comprises two chambers divided by a diaphragm 20, Fig. 4, in which only chamber 28 is in communication with the variable pressure, a push rod 32 attached to the diaphragm and levers 38, 40, carrying counterweights 44, 50 and contacts 42, 48 supported either side of the rod 32. The levers 38, 40 pivot about flexible members 46, 52 insulated from the base 10, as the diaphragm moves. The contacts 42 and 48 engage resiliently mounted switch contacts 54, 56 if the pressure in the chamber 28 is low or high, respectively. The clearance between the contacts may be adjusted by moving contacts 54, 56 by levers extending outside the base 10. The contact 56 mounted on a leaf spring member 72 is prevented from following the contact 48 by a stationary contact 73, Fig. 5 (not shown), which engages the contact 56. The base 10 is earthed and is provided with terminals 86, 90 which are connected through terminals 92, 94 to the flexible members 46, 52.

In a gas chromatography system the position of a recording pen 0, Fig. 1, is converted into a corresponding amplitude significant voltage which signal is then converted into a frequency significant pulse train, by a frequency modulator, demodulator and shaper 2, 3, 4, the pulses of which are then counted 5 so as to produce a count representing the integral of the input displacement with respect to time. The contents of the counter 5 are transferred to relay stores 8 1  to 8p via a switching arrangement 6, 7, at appropriate times, so that each store records data relating to a single gas constituent. The outputs from the stores may be used for any purpose for example in a computer 12 for computing the calorific value of the gas mixture being analysed. In a modification (Figs. 2 and 4 not shown) a capacitor is charged to a level corresponding to the maximum displacement of the pen which charge is then digitised and stored by integrating, with the circuit shown in Fig. 1, the voltage across the capacitor as it discharges through a known resistor.

Abstract: 996,850. Artificial ski-slopes. SKI-DEK CORPORATION. Nov. 13, 1962 [Nov. 14, 1961], No. 42875/62. Heading A6D. An artificial ski-slope comprises an endless belt 16 of material such as nylon pile fabric entrained over rollers 14 and 15, the former being driven from a prime mover 19, means being provided for correcting any lateral displacement of the belt relative to the rollers, resulting from manoeuvres executed by skiers on the slope. The correction is effected by means of auxiliary endless belts 35 entrained in grooves 36 formed in the roller 15 and over grooved pulleys which are supported from the frame of the slope so as to be laterally displaceable relative thereto, the pulleys being connected to displaceable feeler rollers 48 located on opposite sides of the lower run of the belt 16. Thus displacement of the belt 16 results in displacement of the belts 35, so that the latter are fed to their respective grooves 36 at an angle and tend to rise out of the grooves. The weight of the belt 16, however, forces the auxiliary belts back into their grooves, the sloping sides of the grooves causing simultaneous lateral displacement of the auxiliary belts, and the coefficient of friction between the belts 16 and 35 is arranged to be such that the belt 16 is also moved laterally, thereby gradually correcting its original displacement. When the correction is completed, the feeler rollers 48 and grooved pulleys resume their normal positions and the belts 35 resume their movement parallel to the direction of movement of the belt 16 and are located within the grooves 36.

Abstract: 1,253,406. Separating hydrocarbons. MOBIL OIL CORP. 29 Aug., 1969 [23 Sept.,. 1968], No. 43081/69. Heading B1L. [Also in Divisions C4 and C5] A process for recovering condensable heavier hydrocarbons e.g. propane, butane from at least one stream of natural gas lean in these hydrocarbons at least one stream rich in these hydrocarbons comprises flowing the rich gas stream via line 10 to a hydrocarbon recovery means 11, e.g. an oil adsorbent and/or refrigeration means, and flowing the lean gas stream via line 23 to a first adsorbent bed 20 containing e.g. silica gel or activated charcoal. A pre-set amount of the stripped lean gas is diverted to a second adsorbent bed 21 which has been regenerated. The initial effluent from the bed 21 is fed via heat exchanger 41 and conduit 30 to line 10 whilst the remainder is directed back to take off line 24. A portion of the rich gas stream is diverted via line 40 and heat exchanger 41 to heater 44 and thence to a third bed 22 to remove the adsorbed condensables therein. The effluent passes via line 46 to condenser 50 and separator 51, the remaining gaseous phase then being recycled to the rich gas supply line 10. A three way valve 42 actuated by temperature controller 43 diverts a portion of the "regenerative" rich gas stream to a closed loop 48 where, before being directed to the heater 44, it heat exchanges at 47 with hot effluent from the bed 22.
