Title: Improvements in or relating to fork lift devices
IPC: B66F9/18
Filed: 1954-02-04
Abstract: 751,625. Fork lift trucks. SCHWEIZERISCHE INDUSTRIE-GES. Feb. 4, 1954 [Feb. 6, 1953), No. 3344/54. Classes 78 (3) and 78 (4). Each fork of a fork lift truck adapted to lift piles of bricks or a pallet consists of an upper carrying member 14 urged by springs 15 upwardly away from a lower support member 13 and engaging means 21 arranged on at least one side of the upper member connected by first and second link means to the upper and lower members respectively, the arrangement being that upon lifting of the fork the upper member engages the load causing the two members to move together and operate the links means whereby the engaging means is swung outwardly to laterally engage a part of the load. As shown, a frame 10 adapted to be lifted and lowered by any desired means is provided with a horizontal guide 11 on which a pair of slides 12, each carrying a lift fork, are slidable towards or away from one another. A series of pairs of first and second link means, each consisting of a yoke portion 23 of a spiral spring 18 wound on a rod 17 are carried by members 16 depending from the part 14 and a link 24 is pivoted to the yoke 23 and to a plate 25 adjustable vertically on the part 13. When the fork is raised springs 18 are rotated on rods 17 causing rollers 21 carried on rods between the outwardly directed ends of the springs 18 to be forced outwards away from the fork to grip, e.g., the legs K1 of a pallet.

Abstract: 178,590. Brotherhood, Ltd., P., Bryant, C. W., and Jones, G. F. Jan. 28, 1921. Pistons; pistons, cooling.-In an internal-combustion engine the air supply to the carburettor passes through passages in the piston in order to cool the, piston and recover any liquid or gaseous fuel which may leak past the piston rings. The piston head m<1> is connected to the guiding part m<2> by a hollow part m<3> of oval or like section leaving passages o<1>, o<2> at each side between the piston and the cylinder walls. The part m<3> is closed at the top and is connected to the piston head by a web m<4>. A passage h formed in the cylinder wall and communicating with the interior of the cylinder is divided by diaphragms into two parts, one communicating with the atmosphere and with the passage o<1> and the other communicating with the passage o<2> and the carburettor. The passage h is formed troughshaped in order to collect leakage fuel. The air may be circulated through the piston by a fan.

Title: A differential pressure measuring gauge
Inventor: JONES BARTON
IPC: G01L13/02
Filed: 1961-01-30
Abstract: 918,113. Differential pressure gauges. BARTON INSTRUMENT CORPORATION. Jan. 30, 1961, No. 3489/61. Class 106 (2). A differential pressure gauge comprises two housings 11, 12 forming gas chambers on either side of a partition 10 sealed from the atmosphere by packing rings 54 between the housings and the flanges 22, 40 of liquid-filled bellows 14, 16, which are interconnected by a passage 85 in the partition 10 and sealed from the atmosphere by packing rings 23, 43 between the partition and the flanges. Gas or liquid leakage thus takes place into the atmosphere, and the packing rings 23, 43 can be brought into or out of sealing condition by screws 27, 42 independently of rings 22, 40 which can be clamped by bolts 51, 55, these serving also in the embodiment shown to clamp the rings 23, 43. Bellows 14 has a temperature compensating extension 32 communicating with the main bellows via orifices 33. Movement of the bellows against springs 50 displaces a composite stem 63, 62, 61 carried by the end-pieces 20, 37 of the bellows. The stem elements 63, 62 are connected by a sleeve portion 64 through which extends a rocker arm 65, a roller 66 of which bears against a plug 67 in the element 63. Displacement of the stem thus tilts arm 65 and rotates a shaft 68 to give an indication of the pressure differential. Valve elements 81, 83 co-operating with soft valve rings 72, 73 will seal the passageway 85 if the pressure in chambers 13 and 15 exceeds a specified amount. The springs 50 are mounted at one end to anchor ring 45 fixed to flange 40 and at the other end to a spider 35 carried between nuts 83<SP>1</SP>, 84<SP>1</SP> threaded on boss 36 on the end-piece 37 of the bellows, and may be adjusted in tension by rotation of the boss 36.

Abstract: 514,607. Electric transformers. RADIOAKTGES. D. S. LOEWE. Feb. 4, 1938, No. 3552. Void. Convention date, Feb. 5,1937. [Class 38 (ii)] Windings.-The external leakage field of a transformer, used in connection with a cathoderay tube, is eliminated by means of an auxiliary winding, which is arranged external to the core of the transformer and coaxial with respect to the primary winding, and is supplied with current from the transformer circuit, such that it produces a field having the same disposition as the leakage field but of opposite phase. In the form shown in Fig. 1, the transformer has a shell-type core 2 and the auxiliary winding 4 is symmetrically disposed with respect to the primary winding 1, external to the core, and is fed from across a resistance 6 in series with the primary winding. In a modification, the winding 4 is fed from a tertiary winding of the transformer through a phase shifting transformer. In a further modification, for a coretype transformer, Fig. 2 (not shown), the auxiliary winding is in two parts which are placed on either side of the primary winding and coaxial therewith.

Abstract: Tanning agents are prepared by condensing in alkaline solution (a) formaldehyde, (b) polyhydroxyarylsulphone sulphonic acids prepared by heating in vacuo above 150 DEG  C. phenol sulphonic acids either alone or with benzene or naphthalene sulphonic acids and (c) polyhydroxyaryl sulphones obtained by heating the component (b) with a phenol in an amount equivalent to the sulphonic acid groups in the component (b), the heating being under the same conditions as specified above.  The final products may be further reacted with sulphites, or with naphthalene or tetralin sulphonic acids or soluble condensation products thereof with formaldehyde, to increase their water-solubility.  Components (b) and (c) are preferably obtained as a mixture by heating polyhydroxyarylsulphone sulphonic acids with a phenol in amount less than that equivalent ot the sulphonic acid groups present. The phenols used in the preparations may be substituted by halogen or by methyl groups.  In examples, (1) phenol sulphonic acid is heated at 160-165 DEG  C. and 11-13 mm. pressure until the acidity is reduced to a specified degree, whereupon phenol is added and the heating again continued until the acidity is reduced a further specified amount.  The product is made alkaline with caustic soda and condensed at 100-105 DEG  C. with formaldehyde for six hours. The reaction mass is diluted, the tanning agent precipitated with sulphuric acid, dissolved in water and acidified with acetic acid; (2) similar to (1) but using cresol instead of phenol; (3) similar to (1) but after-treating the product with sodium bisulphite, preferably under pressure at 150 DEG  C., or b -naphthalene sulphonic acid; (4) a mixture of phenol and naphthalene sulphonic acids is heated at 165 DEG  C. and 11-13 mm. pressure until the acidity is reduced to a specified degree, whereupon phenol is added and heating continued until the acidity is reduced a further specified amount.  The product is condensed with formaldehyde at 100-105 DEG  C. in alkaline medium for 7 hours.  Toluene may be used instead of naphthalene; (5) a mixture of a naphthylpolyhydroxypolyphenylene sulphone and a polyhydroxypolyphenylenesulphone sulphonic acid is condensed with formaldehyde.  The products of the invention are also useful as assistants in dyeing textiles.  Specification 683,084 is referred to.
