IPC: B26D7/34
Filed: 1916-04-18
Abstract: 105,133. Huxley, H. W., and B. & B. Machine Co. April 18, 1916. Butter-spreaders.-For spreading butter &c. in machines for cutting slices of bread of the kind described in Specification 4217/12, [Class 28 (ii), Kitchen and like appliances &c.], a metallic plate a preferably of aluminium of from # to ¢ inch in thickness, is employed having butter-exuding apertures in the form of elongated slots b or rows of elongated holes, between and adjacent to which are formed, in the body of the plate, parallel holes d in which are put solid metal conductors e lying loosely therein and connected to an external thick disk of copper f which can be heated, say, by a lamp. The butter is contained in a receptacle c, which is secured behind the plate and provided with a piston operated by a screw for forcing the butter outwards. The plate is fixed at a small angle to the surface of the bread to be buttered, so that the portion of the plate over which the loaf last passes when moving across the plate is nearer the loaf than the portion over which the loaf first passes.

Abstract: 1,154,495. Measuring fluid rate of flow electrically. GEORGE KENT Ltd. Feb. 7, 1968 [Feb.8, 1967], No.5995/67. Heading G1N. The mass rate of flow M through a conduit of a gas mixture subjected to high-pressure and temperature is expressed by an equation involving the volumetric rate of flow, determined by the pressure drop across an orifice, and the upstream density, temperature and pressure of the gas mixture, the relationship being based on Van der Waal's equation, and the calculation being performed by an electrical computer. The equation involves the density at standard temperature and pressure, and an alternative equation relates M to the "reduced volume flow" Q at the standard temperature and pressure.

Title: Cyclic process for utilisation of waste pickle liquor
Inventor: JAPPELT ALFRED
IPC: C01C1/242
Filed: 1955-03-01
Abstract: In a process for scrubbing coke oven gas or other gas containing ammonia, hydrogen sulphide and hydrogen cyanide with spent pickling liquor comprising ferrous sulphate and sulphuric acid in counter-current flow so as to produce an ammonical ammonium sulphate solution and a sludge comprising ferrous hydroxide, ferrous sulphide, and ferrocyano compounds, <PICT:0791057/III/1> the sludge and ammonium sulphate solution are separated in a separator 19, the sludge from line 5 together with additional acid from line 3 and optionally water from line 4 is mixed with the spent pickling liquor from line 2 in a decomposition zone 1, the pretreated spent pickling liquor is passed via line 8 to a three-stage scrubbing zone comprising a first section 11 at a pH of 1-7 in which ferrous hydroxide is precipitated, a second section 14 at a pH of 7-9.5 in which further ferrous hydroxide is precipitated, and a third section 16 at a pH of 7-9.5 in which ferrous sulphide and ferrocyano compounds are precipitated, hydrogen sulphide and a residue comprising ferrocyano compounds are recovered through lines 6 and 7 respectively, and the ammonium sulphate solution is passed partly to the second section 14 of the scrubbing zone via line 15 and partly to a crystallization zone 21 for the recovery of ammonium sulphate via line 20.  The process requires that the ammonia content of the gas be at least equivalent to the sum of its hydrogen sulphide and hydrogen cyanide contents, additional ammonia being necessary to neutralize an acid ferrous sulphate solution from the decomposition zone.  The required relative ammonia content may be ensured by scrubbing with ammonia liquor to reduce the hydrogen sulphide content.  The amount of acid added to the decomposition zone may be such as to control the pH of the liquor at 1.0-6.0. The solution from the decomposition zone 1 may be degassed in a degasifier 9 before passing to the scrubbing zone by passing therethrough purified gas via line 12a which is then recycled via line 10 to the crude gas entering the scrubbing zone via line 17. All or part of the ferrous hydroxide precipitated in the first section 11 of the scrubbing zone may be withdrawn therefrom through line 13.  The part of the ammonium sulphate solution to be crystallized may be purified by contacting with gas rich in hydrogen sulphide, e.g. that evolved from the decomposition zone 1 through line 6 the precipitated ferrous sulphide being removed and passed to the decomposition zone, heating, contacting with purified gas in order to remove ammonia and neutralizing with sulphuric acid.

Abstract: 588,962. Making tanks &c. NEWTON, CHAMBERS, & CO., Ltd., WOODVINE, W. T., and HAWKSLEY, J. E. March 12, 1945, No. 6169. [Classes 83 (ii) and 83 (iv)] Uniting by fusion.-In a method of welding a number of plates to form a tank bottom or like metal wall, each plate is slotted in at least one corner to form a tongue, the end of which is removed. The metal adjacent the tongue is displaced out of the plane of the plate, by an amount which is the thickness of the plate, and adjacent plates assembled with the edge of one abutting the displaced edge of another whilst the tongue of this overlaps the first. In such a structure as shown in Fig. 1, two plates 11 and 13 are overlapped at a and a third plate 12 is slotted at 14 to form the tongue which is shortened and the end then bevelled as at 17. The side 15 is bent out of the plane of the plate and lapped under plate 11 at b ; the tongue overlaps plate 13 at c and its end 17 abuts plate 11. The plates are welded together along the top and sides of the lap thus formed as well as in the slot and on the bevelled end of the tongue. The slot 16 has a bevelled edge 18 deepening near the root of the tongue. In a modification, the third plate may overlap the two side plates, one of which is slotted and has the corner piece removed, the slot extending from the top edge. In welding the side 25, Fig. 9, of a tank, to the bottom structure, of plates welded as described, the edges of the tongues of the bottom plates are cut off to agree with the contour of the side before bevelling and the plate corners adjacent the removed ends of the tongues are also bevelled at 28 to accommodate weld metal.

Abstract: 184,822. Giorgini, G. Feb. 24, 1921. Welding wheels.-The beaded edges of wheel rims for pneumatic tyres are electrically welded by roller electrodes inclined to each other. In the form shown in Fig. 2, the electrodes 16, 16<1> are carried by hollow rollers 13, 13' mounted on shafts 10 which are driven from the main shaft by worm and spur gearing. The profile of the electrodes is maintained constant by abutment rollers 17, 17<1> and the electrodes are kept cool by water which circulates through the hollow rollers by way of the nozzle 25, tube 31, ports 30, ports 28, pipe 27 to the exit 21. The housing of the lower roller is mounted on a pivot A and is angularly adjusted by a pivoted screw spindle 22<1> and link 26 to regulate the apparatus to the size of the flange. Deformation of the profile of the flange of the rim 1 is prevented by a roller 18. The rim is pressed into contact with the lower electrode 16' by a pair of guide-rollers 2 carried by levers 2<1> which are pivoted on bolts 4 in elongated slots in a framing secured to the casing of the electrode 16<1> so as to adjust their position according to the diameter of the rim. They are moved into or out of operative position by handles 5. An elastic stop lever 12 provided with handles 8 has slots 8' to engage pins 12' on the levers 2'. Rests 11 are provided to maintain the rim parallel to the lower electrode. In a modification, the rollers 17, 17<1> and 18 are omitted, the deformation being prevented by insulated rings carried on the electrodes adjacent the periphery thereof. The casing of the lower electrode is extended in the form of telescopic tubes containing spring-pressed rods having rollers engaging the internal surface of the rim. In either form, in order to apply pressure to the rim the upper electrode casing is carried by a lever which is connected by a rod to a second lever which is moved by a screw provided with a hand wheel and engaging an internally screwed sleeve secured to the framing.
