Title: Quartz crystal tuning fork vibrator
IPC: H03H9/13
Filed: 1977-10-20
Abstract: A quartz crystal tuning fork vibrator comprises a monolithic quartz crystal vibrator having a tuning fork shape with a plurality of vibratable tines. A set of electrodes are adhered to opposite surfaces of the tuning fork vibrator and are arranged in such a manner that when suitable alternating voltage is applied thereto, the tines undergo flexural vibration in their fundamental or resonance mode. The electrodes on each tine surface are preferably arranged in groups of four with the center two being applied with voltage of one polarity when the outer two are applied with voltage of the other polarity thereby establishing electric fields within the tines at the outside portions thereof while no electric field is established at the center portion of the tines. All of the flexural strain is thus confined to the outside portions of the tines thereby lowering the amplitude of vibration of the tine ends to the order of 5 mu -10 mu .

Title: Method and apparatus for carrying out exothermic gas reactions
IPC: B01J8/02
Filed: 1965-10-20
Abstract: Catalytic, exothermic gas reactions, particularly the synthesis of ammonia from nitrogen and hydrogen, are carried out by pre-heating the reactant gas by heat exchange with hot product, passing the reactant gas through one or more tubes extending through the catalyst bed in the same direction as the gas flowing through the catalyst itself, and after mixing this reactant gas with further, cold reactant gas, it is passed again through one or more tubes extending through the catalyst bed in the opposite direction to the gas flowing through the catalyst itself, and finally reacting on flowing through and contacting the catalyst itself, which is maintained by this method at the desired temperature, e.g. 450-550 DEG  C., particularly for the synthesis of ammonia.

As described the conveyor belt 3 passes around driven roller 4 and tensioning roller 5 and is supported by rollers 7. A batch of footwear placed on the conveyor 3 is moved initially to a vacuum treatment station where a bell chamber 9 is lowered by pneumatic or hydraulic cylinders 10 and seals against a plate 8 between the upper and lower parts of the belt 3. Steam is injected into the bell chamber 9 from a boiler 13 through a conduit 13a and the chamber is then evacuated by a pump (not shown). The batch of footwear then enters a tunnel 18. In a first region in the tunnel 18 the footwear is treated with steam from a nozzle 20 supplied by a conduit 21 from the boiler 13. The batch then moves to a region 22 having heaters 23 and a fan 24 to dry the footwear, and moves to region 25 where the heated air continues the drying. These last two steps are repeated at stations 26 and 29 and the footwear is removed from the conveyor after passing through a closure flap 30.

Title: Apparatus for producing textured yarn
IPC: D02G1/02
Filed: 1964-11-11
Abstract: In a multistation machine for producing textured e.g. stretch, bulked, lively, fluffed, yarns of natural fibres such as cotton, linen and wool, each untextured, continuously running yarn is directed (under minimum tension) by a double U-shaped guide into and through a bath containing material reactive (as described in Specification 1,064,698) with the yarn to produce the texture. The impregnated yarn passes (under uniform tension) through a twostage, electric, radiant heater, then through a false-twisting spindle whereby the yarn is twisted before passage through the heater and untiwisted after removal therefrom.  In the first heating stage the yarn is heated to eliminate excess material and in the second stage the temperature is such as to react the material and thus set the twist in the yarn.  Waste fumes expelled from the yarn in the vicinity of the false-twister are collected by a baffle and removed pneumatically through a suction duct through which waste lint and dust are also withdrawn.
