Title: Improvements in or relating to the preparation of metal gluconates
Inventor: JNR JAY SELLECK BUCKLEY
IPC: C07C51/31
Filed: 1955-04-15
Abstract: A metal gluconate is prepared by contacting an aqueous glucose solution having a concentration of at least about 20 per cent, preferably at least 30 per cent, by weight, said solution containing a noble metal catalyst, with an oxygen-containing gas at a temperature not higher than about 55 DEG  C. and at a pH which, by gradual addition of an inorganic alkaline material until one equivalent of alkaline material per mol. of glucose is consumed, is continuously maintained between 8.0 and 11.0, the pH used at any given temperature being chosen so as to minimize decomposition.  The pH is preferably kept within the range 8.0 to 9.5 at about 55 DEG  C. and within the range 9.0 to 11.0 at about 25 DEG  C.  The preferred catalyst is palladium supported on an inert carrier such as charcoal, the amount of catalyst metal being 0.05-1 per cent by weight of the glucose.  Platinum catalysts of a similar type may also be used.  The solution to be oxidized is preferably stirred vigorously throughout the reaction, the oxygen-containing gas being introduced through a porous disc or pipe.  If air is used, at least one half volume of air per volume of solution per minute is used.  The preferred alkaline material is an alkali metal hydroxide, although alkaline earth metal hydroxides, such as barium hydroxide, also may be used.  The alkaline material may be added in solid form but it is preferred to use a concentrated aqueous solution, e.g. about 25 per cent concentration, the addition being controlled by utilizing a continuously reading pH meter with its electrode immersed in the reaction solution.  After completion of the reaction, the catalyst is removed by filtration or centrifuging and washed with water. The reaction solution may be concentrated or a suitable water-miscible solvent, e.g. methanol, may be added to obtain the solid gluconate.  Alternatively the whole solution may be evaporated to dryness, for example, on a heated rotating metal drum, preferably after adjusting the gluconate solution to a pH of 6-7.  Detailed examples are given in which the catalyst comprises palladium on charcoal or palladium on alumina, the alkaline material is aqueous sodium hydroxide and the solid gluconate is obtained either by addition of methanol or by drum-drying the reaction solution.

Title: Improvements in or relating to epoxide resins
IPC: C08G59/18
Filed: 1961-03-24
Abstract: A solid resinous product comprises an epoxide resin and a hardener therefor present together in a homogeneous but only slightly cross-linked state.  The hardener is an organic anhydride, phenol, urea or melamine resin.  The composition contains no organic metal compound.  The product which is preferably in the form of a powder or granules is formed by mixing melts of the ingredients, rapidly cooling the mixed melt, and comminuting the solid product. Fillers, e.g. quartz meal, graphite, metal powder, glass fibre reinforcement esterless, dyestuffs, or foaming inhibitors may be included in the compositions which may be cured by heat treatment, if desired in a mould e.g. by centrifugal action in a tube mould.  Alternatively the product may be shaped by casting or sintering processes.  The epoxide resins used are condensates of epichlorhydrin with polyhydric phenols.  In Example 1 the hardener is phthalic anhydride.  In Example 2, a butylized phenolformaldehyde resin is used with phthalic anhydride. In Example 3, quartz meal and titanium dioxide are stirred into molten epoxide resins, and the mixture then further mixed with molten phthalic anhydride and cooled.

Title: Improvements in or relating to high pressure lubrication fittings
IPC: F16N11/04
Filed: 1932-04-21
Abstract: 400,253. Lubricators. MACINDOE, J. F., 3603, Queen Lane, East Falls, Philadelphia, U.S.A. April 21, 1932, No. 11496. [Class 12 (iii).] In a lubricator comprising a passage 15 having an inlet closed by a check valve 20, an outlet 13 for connection to a bearing or the like, and a lubricant chamber offset from the passage 15, the chamber is of telescopic form, being expanded by the injection of lubricant by means of a grease gun or the like through the inlet, and collapsed to expel lubricant as required from the outlet 13 on withdrawal of the gun. The telescopic chamber comprises a fixed chamber 11 and a hollow plunger 28 sliding in an opening 30. The plunger 28 is urged inwardly by a spring 34 abutting a packing washer 35 and a flange 33. An opening 32 in the plunger 28 is restricted by the cylindrical part of a fixed control member 36 for approximately one quarter of the stroke of the plunger. However, the narrower part of the member 36 entering the opening 32 compensates the weakening of the spring and the feed is thus kept substantially constant. The check valve 20 may be of the built-in type as in Fig. 1, or a fitting adapted to screw into the passage 15. A projection 37 on the plunger 28 limits its inward movement so that a certain amount of lubricant is always left in the device and may be utilised when the bearing runs hot. In a modification, the control member is dispensed with, the passage 13 in this case having a restricted outlet, and projections in the passage 15 limit the collapse of the plunger.

Title: Step-by-step feeding device for cutting, punching or stamping machines
IPC: B21D43/11
Filed: 1948-04-27
Abstract: 653,660. Punching; metal-sheet feeds. HALLER, J. April 27, 1948, No. 11513. [Class 83 (iv)] A step-by-step feeding device for feeding sheet-metal 81 to a cutting, punching, or stamping machine 10 comprises means for moving a work-support 29 towards and away from a stationary support 26, and a pressurefluid distributer synchronized with the movement of the support 29 for supplying pressurefluid alternately to a fluid-actuated workclamp 11, 12 mounted adjacent each support so as to clamp the work-piece against the respective support. The work-piece 81 is operated upon by a punch 16 and die 20 mounted on a base 14 which also supports by means of bolts 22 a pair of rails 24 between which the movablesupport 29 is slidably received in V-recesses. The support 29 is reciprocated by a doubleacting ram 34, which may have an adjustable stroke, and cylinder 36 connected by pressurefluid pipes 41, 42 to a cylinder 13 and doubleheaded piston 48 forming the distributer. The head of a lever 53 provided with projections 55, 56 and stroke-adjusting stop-screws 57, 58 to co-operate with a projection 59 on a lever 60. The latter is attached to a bracket 63 on the press 10 by a pin 61 bearing in a slot 62 in the bracket so that as the press is fed downwardly the lever 60 is operated to actuate the piston 48. As the piston is moved to the right, pressure-fluid in the pipe 42 causes the ram 34 and support 29 to move to the right and pressure-fluid to pass along a branch pipe 68 into the clamp 11 mounted on the support 26 which extends between the rails 24. The clamp 11 and the clamp 12, which is attached to the movable support 29, each comprise a block 65 having a wedge-shaped recess 78 housing a roller 76. Pressure-fluid acting behind one or more spring-pressed pistons which bear on the roller 76 and are housed in the block 65, forces the roller 76 against the inclined wall of the recess 78 and into binding engagement with the work-piece 81. During the downward movement of the press the workpiece is held stationary by the clamp 11 as the support 29 and clamp 12, which has been exhausted of pressure-fluid by a flexible pipe 69 connected to the pipe 41, are moved to the right. As the punch is raised from the die 20, the piston 48 is moved to the left to force pressure-fluid into the pipes 41, 69 and withdraw it from the pipes 42, 68 in order that the clamp 12 may grip the work-piece 81 and feed it towards the press, the gripping pressure of the stationary clamp 11 being released by suction in the pipe 68. The work-piece 81 is guided between adjustable rollers 84 which are mounted in T -slots 88 adjacent the cylinder 36.

In a constant support for pipes, of the kind comprising a pair of cam pulleys 12 pivoted at 13 between a pair of mounting plates 10 and connected by chains 14 to spring-loading devices 20 pivoted to the plate 10, radial arms 21 on the cam pulleys 12 are connected to a support rod 23 for the pipe, not shown, through a step-down gearing system such as lazy tongs levers 24, 25 so that a certain movement of the support rod 23 produces a corresponding reduced movement of the radial arms 21. The arrangement can also be applied to a support having only one cam pulley the upper end of the spare lever 24 being pivoted to a pin secured between the plates 70. In a modification, Fig. 3 (not shown), the cam and arm mechanisms 12, 21 are replaced by rockable triangular plates which are pivotally connected to the upper levers of the lazy tongs and also to the spring-loading devices by means of articulated pairs of links.

[Class 54.] The space above the disc plunger 2 of a dry gas holder is open except for a reinforcing framework 11 and the plunger is fitted with an electric heating device 19 for melting any snow falling upon it. Melted snow or rain water collects at the lowest part 12 of the plunger and is removed by a pump 13 through a jointed pipe 14. A suitable oil or other non-freezing liquid may be supplied by a pump 15 to a channel 16 at the top of the holder so as to flow as a film down the inside of the wall 1 to prevent the deposit of frost or ice. The oil is collected in a channel 18 on the plunger 2 and is pumped away through a pipe 21. Oil percolating through the leather ring of the plunger seal 22 and oil escaping from the channel 18 past the seal 22 is collected in a channel 23 at the bottom of the holder and thence raised by a pump 24 to the top of the holder where it is discharged from a pipe 25 on to a chain 26 leading to a tank 27 on the plunger communicating with the seal 22 by a pipe 28. The plunger is guided by cables 5, 6 which run over rollers 7, 8 and pass through liquid seals 9 on emerging from the gas space.
