Title: Safety head for skis
IPC: A63C9/08
Filed: 1963-02-07
Abstract: 1,025,998. Ski bindings. P. UNGER. Feb. 7, 1963 [Feb. 7, 1962], No. 5078/63. Heading A6D. A safety device for fastening boots to skis, comprises a housing on the ski containing a displaceable member which is coupled to an abutment for locating the boot on the ski the displaceable member being capable of spring-controlled rotational and longitudinal movement in response to forces developed between the boot and the ski. As shown in Fig. 1a, the housing 1 comprises a bearing sleeve 5 for a bolt 2 which comprises the displaceable member, and which is secured at one end to a crank 6 pivotally supporting the abutment 7. The bolt is normally held in the position shown in Fig. 1a by spring-urged balls 9,15 engaging respectively the inclined surface 10 or the groove 14 of the bolt, but in the event of the skier's falling forwards or sideways the bolt moves longitudinally and/or rotationally to move the abutment 7 away from the boot. Alternatively, as shown in Fig. 5a, the displaceable member 28 may be hollow and mounted for longitudinal displacement in a housing 31, and for pivotal movement about the axis of the pin 30. The member 28 is normally held against displacement by a spring- controlled detent 22, but in the event of the skier's falling forwards or sideways the resultant movement of the member 28 lifts the detent which in turn lifts the member 23, brings the pivot 25 of the plunger 26 beyond its dead centre position, whereupon the spring 27 becomes operative to release the member 23 and retract the abutment 7.

Title: Rejuvenation of porous diaphragms
IPC: C25B13/06
Filed: 1966-02-04
Abstract: An asbestos diaphragm in a chlorine-alkali electrolytic diaphragm brine cell is rejuvenated to restore its liquid permeability by contacting it with an aqueous solution of an acid having an ionization constant greater than 10-5 until the solution passed through the diaphragm has a pH less than 8.  As described the cell comprises vertical graphite blades secured in the cell bottom between which pass flattened tubular steel mesh cathode members connected to each other at their ends and to end half cathodes by steel mesh, thus forming a single cathode structure, and asbestos is deposited on the cathode to form a porous diaphragm dividing the cell into separate anolyte and catholyte compartments.  After prolonged use, the brine is drained from the catholyte compartment of the cell and acid is introduced into the anolyte compartment and withdrawn from the catholyte compartment.  The acid employed may be acetic, formic, sulphuric, phosphoric or phosphorous acid but preferably is hydrochloric acid.  To prevent attack of the steel cathode the acid solution may include corrosion inhibitors such as aliphatic or heterocyclic amines, alkanolamines, aldehydes, chromates, glycerine, sugar or molasses.ALSO:An asbestos diaphragm in a chlorine-alkali electrolytic diaphragm brine cell is rejuvenated to restore its liquid permeability by contacting it with an aqueous solution of an acid having an ionization constant greater than 10-5 until the solution passed through the diaphragm has a pH less than 8.

Abstract: 1293401 Raising liquified gas; jet pumps HYMATIC ENG CO Ltd 2 Feb 1970 [3Feb 1969] 5783/69 Headings F1E and F1R [Also in Divisions F2 and F4] In a cryogenic refrigerating apparatus in which a liquified gas is passed from a reservoir to an evaporator through a delivery tube, the entry end of the tube is provided with an injector which is connected to the liquid and vapour spaces in the reservoir so that the flow of vapour from the reservoir into the tube entrains droplets of liquid. As shown in the plan view of Fig.3, a liquid nozzle 27 directed towards the tube 11 communicates through a vertical passage 51 with the reservoir liquid space. A convergent passage 28 surrounding the nozzle is connected through a pressure regulator 37 to a further vertical passage 43 which communicates with the reservoir vapour space. The regulator 37 comprises a seating 39 against which a diaphragm 38 is adjustably biased by a spring 40 to maintain the required pressure in the passage 28. A pressure relief device 50 which also includes a spring- biased diaphragm communicates with the passage 43 to limit the pressure in the reservoir vapour space. The evaporator may take the form shown in Fig.4. The tube 11 delivers liquid through a vertical passage 61 to a Dewar vessel 63 which includes a load 15 to be cooled. Vapour passes from the Dewar through openings 73 into the passage 61 and, together with vapour from the delivery tube 11, leaves the system through openings 68 and a discharge line 80 controlled by a valve 75. The valve 75 is operated by a fluid filled bellows 72 which communicates with a sensing bulb 87 so that the valve closes to prevent further delivery of liquid when a predetermined liquid level is reached in the evaporator. The sensing bulb 87 is screened by a shield 67 from contact with liquid which is entering the Dewar.  In alternative arrangements (not shown), the sensing bulb may control a valve in the delivery tube itself, the bulb may be extended horizontally to give a faster valve operating action; or the bulb may be provided with a downwardly extending tail to give a more progressive valve action. A needle valve may control the flow of vapour to the injector in accordance with the pressure in the supply pipe.
