Title: Pneumatic differential pressure amplifier
IPC: F15B3/00
Filed: 1970-08-10
Abstract: 1277148 Fluid regulation J C ECKARDTAG 10 Aug 1970 [3 Nov 1969] 38464/70 Heading G3H In a pneumatic differential pressure amplifier 1, control of flow between an inlet 7 and two outlets 8 and 9, is effected by means of two abutting ball-members 4 each of which is operatively engaged by the stem 5 of a diaphragm 6, the outer sides of the two diaphragms being subjected to controlling pressures. Thus, in the event of the two pressures being equal, the amplifier assumes the state shown. Upon such pressures attaining different values, one of the balls tends to obstruct its associated outlet whilst the other tends to open its associated outlet, the proportional degree of change in the section of each outlet being the same Fig. 5 (not shown). The outlet passages 8 and 9 each lead from tapered slots 10, which slots open into the ball-accommodating bore 3 of cylindrical inset 2 and extend in a direction generally trans-  versely to the outlets, Fig. 2 (not shown). In a modification, Fig. 3 (not shown), each output passage connects two branch passages each of which leads from a tapered slot, there being in this arrangement two slots for each ball symmetrically disposed one on either side of the bore 3.

Abstract: 1,188,869. Electrocuting poultry. STORK AMSTERDAM N.V. 12 Aug., 1968, No. 38552/68. Heading A1M. A device for electrocuting poultry has a conveyer 4 supplying poultry hanging by their legs to a basin 5 filled with an electrically conductive liquid 20 positioned below the conveyer, the legs of the poultry and liquid 20 being electrically connected to opposite poles of an electrical source 14. The basin 5 is constructed from an electrically insulating material and contains an electrode 10 connected to the secondary coil 13 of a transformer 14. The other terminal of the coil is earthed and connected to electrode 17 with which the legs of the poultry come into contact. The voltage of the secondary coil 13 is 40-45 volts.

Patent GB-386064-A (GB)
Abstract: 386,064. Snap - action switches. BRITISH THOMSON HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Mayer, F. ; 1728, Luna Avenue, Chicago, U.S.A.) Oct. 21, 1931, No. 29256. Convention date, Oct. 21, 1930. [Class 38 (v).] A quick - action switch, suitable for thermal actuation, has an insulating base moulded with a beading round the edge on which is supported an adjustable fixed contact 16. A resilient contact-strip 18 has a bent-round end portion 18a which serves for mounting the strip on the base and also to connect it to a terminal 26 by means of a strip 27. The strip 18 is so formed that when touching the fixed contact 16 it is still flexed and if free would bend so as to increase the angle between the parts 18, 18a. A bowed spring 33 is mounted between a fixed knife-edge 31 and a knife-edge aperture 32 in the strip 18. On the application of an upward force to an operating arm 23, the strip 18 unbends but the flexure of the free end maintains contact pressure until the point 32 passes the dead-centre whereupon the switch opens with a quick action until arrested by a stop 34. On removal of the operating force the switch closes due to the springiness of the strip 18. A stop 35 is provided for the operating member. The switch may be operated by a pin on an arm rotated by a bimetallic spiral and the whole switch is mounted for rotation to vary the temperature setting. Specification 280,323, [Class 38 (v), Electric switches &c.], is referred to.

Title: Refining petroleum wax by contact filtration
IPC: C10G25/03
Filed: 1957-12-12
Abstract: Petroleum waxes are refined by contacting them at 150 DEG  to 450 DEG F. with a molecular sieve having a pore size of 10 to 15  .  The wax may be a paraffin or microcrystalline wax and it is preferably de-oiled to an oil content of less than 1% with a solvent such as propane or M.E.K.  The Specification includes a summary of the conventional methods of extracting waxes from petroleum oils and de-oiling waxes including chilling, solvent de-waxing of oils, sweating, solvent de-oiling of waxes, H2SO4 treatment or mild hydrogenation (600 DEG  F., 200 p.s.i.g.) and percolation through adsorbent clay.  The contacting is preferably conducted at 300 DEG to 400 DEG  F. for 5 to 60 minutes using a 13   sieve.  Used sieves may be regenerated by washing with solvents, e.g. hexane, secondary butyl acetate and M.E.K. mixed with toluene, but regeneration by heating at 700-800 DEG  F. for 1 to 10 hours with a regenerative gas consisting of nitrogen containing less than 2 vol. per cent each of oxygen and water, less than 0.7 vol. per cent of SO2 and minor amounts of carbon dioxide is preferred.  Examples of the treatment with a 13  sieve of paraffin wax extracted from a lubricating oil extract which had been de-oiled by sweating and acid treated demonstrate: (1) the relative effectiveness of (1) 5% and 20% wt. of the sieve and conventional adsorbents at 300 DEG  C.; (2) 20% wt. of the sieve and conventional adsorbents at 400 DEG  C.; (3) 5% wt. of fresh, solvent regenerated, and heat regenerated sieve at 300 DEG F.; and (4) 5% wt. of the sieve at 300 DEG  and 400 DEG  F. Preparation of the sieves.-The sieves used are zeolites which may be synthetic.  A 13   sieve may be prepared by reacting a sodium silicate of high Na:Si ratio, e.g. sodium metasilicate, with a sodium aluminate having a Na:Al ratio between 1:1 and 3:1 in proportions to give a Si:Al ratio of at least 3:1, preferably between 4:1 and 10:1. The resultant precipitate is heated (as a homogeneous paste) at 180-215 DEG  F. for about 200 hours, filtered, water-washed, dried and calcined at 700 DEG  to 900 DEG  F.

As shown in Fig. 2, each slot 7 has a relatively narrow entry portion 11 leading to a larger main portion 12 dimensioned to receive the tube diameter, and each aperture 10 comprises end portions 13, 14 each generally similar in size to the portion 12 of slot 7, and interconnected by a relatively narrow portion 15. Flanges 35 may be formed around the said portions 12, 13 14 for strength and to serve as fin spacers. The tube coil before assembly is shaped as in Fig. 3 with the outermost passes 20 at an angle to the other passes and deformed to a flattened cross-section such as shown in Fig. 4. The bends 21 interconnecting the other passes are also initially of flattened cross-section so that each pair of other passes and the associated bend can be passed on assembly, through aligned apertures 10 in the block of fins. Thereafter the outermost passes 20 are moved inwardly into the main portions 12 of the slots 7 and finally the tube is expanded so that the flattened sections thereof resume a cylindrical form and are held in contact with the fins without the use of a bonding material. During the expansion, dies (D 1 , D 2 , Fig. 5) are used to maintain the outermost passes in position in the slots 7 generally as described in Specification 1,234,270. Fig. 1 shows an arrangement wherein in each vertical row 16, 17, 18, 19 of the passes 20 fluid flow in adjacent passes is in opposite directions. In a further arrangement (Fig. 7) fluid flow is in the same direction in all the passages in any one vertical row but is in opposite directions in adjacent rows. The tube coil 2 is preferably a onepiece structure of aluminium and the tube fins also of aluminium are 0À006 inch thick.
