Abstract: 630,931. Tilting-appliances. HART, J., and BAKER PERKINS, Ltd. May 22, 1947, No. 13763. [Class 21] [Also in Group XXX] Biscuit dough is supplied to dough treating machines in pans 9 attached to cradles 4 which are provided at the rear with a hook 7 or like means for pivoting about a horizontal axis in the region of the pan rim or between the rim and the bottom of the pan, and at the front with means 13 for receiving a hook 12 of a hoisting gear, so that the pan and cradle together may be turned about the horizontal axis to present the mouth of the pan in a convenient position for feeding the dough to the treating machine. The cradle comprises angle irons 5 bent upwardly to form vertical portions 6 provided with hooks 7 adapted to engage over a fixed horizontal bar 3 to which they are secured by bolts 8 to form a trunnion. Normally the angle irons 5 are horizontal so that the pan 9 on its wheels 10 may be wheeled over the angle irons 5 to engage a shaped backing 14 on the vertical irons 6. The pan is then locked in place by a gate 11, the hook 12 is engaged with a stirrup 13 and the lifting means 17 is operated to tip the pan and cradle through a right angle or less, the tipping being limited by a chain 16. Alternatively the cradle may be provided with wheels, the pan 9 being permanently on the cradle, and the hooks 7 being releasably attached to the bar 3. The hooks 7 may be replaced by a horizontal bar on the cradle 4 adapted to be received in fixed bearing sockets. The structure 1, 2 shown supporting the bar 3 may be hinged about a vertical axis so that it may be swung out of position when not required.

Title: Process of preparing diresorcyl sulfide
Inventor: MOORE RALPH GOWER DAVIES
Filed: 1956-05-04
Abstract: Diresorcyl sulphide (4 : 41-thiobisresorcinol) is made by reacting sulphur dichloride dissolved in a dialkyl ether containing not more than 6 carbon atoms with a solution of resorcinol in such an ether at a temperature of 0-15 DEG  C.  Ethers specified are ethyl methyl ether, diethyl ether, ethyl propyl ether, di-isopropyl ether, and n-butyl methyl ether.  The product is isolated by distillation of the ether at below 60 DEG  C. either with or without a prior treatment with aqueous alkali-metal carbonate solution, or by extraction of the product from the ether with sodium hydroxide solution followed by acidification of the alkaline extract to precipitate the product. The diresorcyl sulphide is then crystallized from water at below 60 DEG  C. Examples illustrate the preparation of diresorcyl sulphide by reaction in diethyl ether and di-isopropyl ether.

Filed: 1972-03-24
Abstract: 1366781 Buffers L F BLATT 24 March 1972 [5 April 1971] 13906/72 Heading B7L A reciprocating mechanism for supporting a load handling device, e.g. a gripper head comprises a shuttle unit 38, Figs. 1 and 2, mounted for reciprocable movement along a track 14; a reciprocable slide assembly including members 64, 68 and 70 which is mounted for movement along slideways 74 extending longitudinally of and carried by track 14 and which supports a shock absorber 56 for absorbing the kinetic energy of the shuttle unit 38 at an end of its stroke; and screw means 94 which extend through an internally threaded aperture of the slide assembly at 90 and which are retained against movement longitudinally of the track at 96 and 104, so that rotation of the screw means 94 by movement of hand wheel 116 causes longitudinal movement of the slide assembly and shock absorber 56 supported thereby to adjust the limit of travel of the shuttle unit 38. The screw means 94, which extends between an end cover 24 of the track 14 at 104 and a bulkhead 50 of the track at 96, is releasably lockable against rotation by a nut 108 and lock washer (112), Fig. 4 (not shown), the nut 108 being rotatable by a lever 110 to lock the washer against end cover 24. The shock absorber 56 comprises a fluid cushion cylinder 58 from which extends a piston-rod 60 terminating in a bumper (61), Fig. 3 (not shown), normally biased outwardly of cylinder 58 by a spring 62. The shuttle unit 38 may be driven along track 14 by a fluid motor, including a stationary hydraulic cylinder 48 and piston-rod 49 operably connected to unit 38, and is guided by rollers 32 engaging bearing surfaces 29 of the track 14. In another form, Fig. 6, the slide assembly which supports shock absorber 56a comprises a mounting bracket 134 which extends transversely of the track and has grooves 142 at its opposed ends engaging slideways 74a of the track. Releasable clamping means are formed by screws 148 which lock the bracket 134 on to the slideways 74a through resiliency supplied by the provision of slots 144 intersecting the grooves 142. The shock absorber 56a can be moved relative to its supporting slide assembly by an adjusting screw 150.

Title: Improvements in or relating to the manufacture of polymerisation products
IPC: C08F14/06
Filed: 1942-10-05
Abstract: Toluene-soluble polyvinyl chloride of improved colour stability is produced by polymerizing vinyl chloride in an aqueous emulsion containing a per-compound as catalyst and in the presence of a small amount of formaldehyde.  It is preserred to use between 0.005 and 0.025 parts by weight of formaldehyde for every part of vinyl chloride.  Suitable emulsifying agents are alkali metal and ammonium salts of sulphonated long chain hydrocarbons or fatty acids, e.g. oleic, lauric, palmitic or stearic acids; agar-agar, gelatine, gum tragacanth and soluble starch.  Catalysts mentioned are hydrogen peroxide, and benzoyl or succinyl peroxides; potassium or ammonium persulphates or percarbonates.  Plasticisers or softeners for the polyvinyl chloride may be included in the reaction mixture.  In an example, an aqueous emulsion of vinyl chloride containing the sodium salt of a highly sulphonated oleic acid, ammonium persulphate, sodium hydroxide and formalin solution is polymerized.  The latex is precipitated by lead acetate and a sheet is prepared from a composition of the dry product and tricresyl phosphate, dibutyl phthalate titanium oxide and lead silicate.
Patent GB-446607-A (GB)
Title: Improvements relating to the centrifugal de-waxing of oils
IPC: C10G73/28
Filed: 1935-05-13
Abstract: Wax is separated from oil in a centrifuge, and its kinetic energy is used to withdraw it in a confined stream from the whirling zone, for instance, by means of a skimming tube with sharpened edges.  The waxy oil is mixed with a solvent consisting of carbon tetrachloride <PICT:0446607/III/1> and dichlorethane, and cooled to precipitate the wax.  It is then passed through the pipe 1 into the drum 8 of the centrifuge.  The separated oil passes through the apertures 5 at the top of the drum wall, into the chamber 6 between the walls 8, 9, and discharges through the overflow tubes 7.  The separated wax is carried by its kinetic energy through the tube 10 which can be adjusted along the surface or into the liquid by screws 12 in collars 13, 14.  A washing fluid may be supplied through the pipe 4.  To increase the fluidity of the wax, a solvent may be sprayed on it just before it enters the tube 10 or it may be heated after entering the tube.  The inner wall 8 of the centrifuge may be covered with a filter blanket, so that the oil passes through it and the wax remains on it for removal mainly by the tube 10; the last layer of wax, however, is floated off by a heavy wash liquid and then removed by the tube 10.

Abstract: 929,924. Nuclear power plant. SULZER FRERES S.A. April 11, 1962 [April 28, 1961], No. 14005/62. Class 39 (4). In a nuclear reactor power plant the heat of the reactor is absorbed by a coolant and transmitted in a heat-exchanger, which is divided into two parts 10 and 13, to a working medium flowing in at least two vapour generators 14 and 15 in counter-current to the coolant, the vapour generators operating at different pressures and the working medium then performing work in a turbine 20, the reactor having at least two zones of different heat evolution with different coolant output and input temperatures, the coolant being fed to and discharged from the heat exchanger at different inlet and outlet points according to its temperature, and a coolant circulating blower 11 being placed between the two parts of the heat-exchanger. As the centre zone of the reactor core 1 is the hottest then this zone is cooled by the coolant from the pipe 3 which is at the lowest temperature. The middle and outer zones are cooled by coolant from the pipes 5 and 7, the coolant in pipe 7 being hotter than that in pipe 5 as it is fed directly from the blower 11. Also the outlet pipe 8 contains coolant at a higher temperature than that in pipe 6. The coolant is gaseous, e.g. CO 2 , and the working medium is water.
