Abstract: 204,723. Vogtlõndische Maschinen- Fabrik vorm. J. C. & H. Dietrich Akt.-Ges. Sept. 30, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Delivery apparatus.-A number of oscillating gripper-flyers arranged side by side on a common shaft are moved apart axially simultaneously with their oscillating movement so that the printed sheets or book parts, which are close together when taken by the gripper-flyers, can be deposited in the partitions of an endless conveyer at the proper distance apart. The flyers 1 carried on the shaft 2 are oscillated between the dotted line positions to deliver the sheets to the partitions 14 of the delivery conveyer, the sheets being held by grippers 4 closed and opened at the proper times by abutments 11, 13. One flyer is rigid with the shaft 2, but the others are carried by sleeves 17 slidably keyed to the shaft and connected by rods 21 to different points on the arms of a lever 22 mounted on a vertical shaft 23. The latter is oscillated by means of an arm 24 adjustably connected by pivot holes 25 to a link 26, and a lever 27 rocked by a cam 29. The shaft 2 is oscillated by a pinion 35 gearing with a toothed sector on a bell-crank lever 33 rocked by a cam 31. The abutment 11 which closes the grippers is movable and actuated by a lever 37 carrying a roller 36 engaging a cam 32. A spring-rod engages an arm on the gripper shaft so as to maintain the grippers in open or closed position.

Abstract: 393,805. Moulding flexible brush backs; vulcanizing-moulds. WESSEL, W., 112, Hindenburgstrasse, Remscheid, Germany. Sept. 2,1932, No. 24504. [Classes. 70 and 87 (ii).] Flexible brush backs are formed from an elastic material, such as rubber, the holes for the reception of the tufts or bristles being produced during the moulding of the back. The mould comprises an upper part 1 and a lower part 2 carrying studs 3 for forming the holes in the brush back. The studs 4 at the periphery are disposed somewhat obliquely while those in the centre are vertical' and they abut against the top 1 when the mould is closed. In a modification the studs are reduced at their upper ends 9. When it is desired to secure the bristles by wires, grooves for the reception of the wires are formed in the brush back by ribs 10 on the top mould part which may be either broader or narrower than the studs 3 and may be arranged in circles or zig-zag form. In a further modification, Fig. 8, the studs 11, 12 are carried by a plunger 13 which is slidable in the mould part 2 and retained by a screw 14 so that the studs can be withdrawn from the moulded brush back before the mould is opened. The mould parts are brought into register by pins 6 engaging holes 7 and the mould is first filled with pieces of rubber and then heated to soften the rubber and finally vulcanize it. The brush back may have an ornamental design formed on it or may be provided with an additional backing.

Title: Improvements in or relating to machines for manufacturing pipes and tubes
IPC: B21C37/12
Filed: 1961-07-07
Abstract: 922,000. Making helically seamed tubes. L. KEYNE, and T. LANGEN. July 7, 1961 [July 14, 1960], No. 24704/61. Classes 83 (2) and 83 (4). [Also in Group XXVIII] A machine for manufacturing pipes of different diameters made from helically wound strip with a closed seam includes a strip feeding device and a plurality of pipe shaping tools 8 mounted in a jaw-portion of a support 1, the feeding device and the support, or a table 2 which forms a part of the latter, being angularly adjustable relatively to one another and the pipe shaping-tools being adapted to bear from the exterior only against the pipe being formed around an arc of at least 120 degrees, and being adjustable radially relatively to the axis of such pipe asymmetrically in the jaw-portion, so as to suit the position of the axis of the pipe being formed, which position is dependent upon the desired diameter of such pipe, the use of an internal mandrel or adjustable internal shaping tools being unnecessary. As shown a pair of tools 8 are mounted on each bridge member 7 which interconnects a pair of externally threaded shafts 6, one being shown and the other being mounted on a second jaw I behind the illustrated one. A sleeve-shaped sliding member 9 is fixed to the inner end of the shaft 6 on the other end of which engages a structure 10 mounted on an outer guide 5 and comprising a worm 11 which engages a gear 12 mounted on the shaft 6. This arrangement allows the tool 8 to be adjusted radially inside an outer guide 5 which is pivotable in passages 3 to allow the tool to be also adjusted angularly. The lower two pair of tools 8 need only be capable of radial adjustment. A wear-resistant strip entrance 13 may replace the lowermost passage 3. Instead of the two-part stand supporting the tools 8, it is possible to use a single stand wherein each passage 3 is in a single section. These sections are positioned side by side so that the passages are staggeredly arranged after each other in the direction of rotation of the strip. In a modification, the tools 8 are mounted in annular or cruciform-shaped grooves in a stand side by side in a staggered arrangement one after the other in the direction of rotation of the strip. A plurality of counter jaws can be used. In another modification the tools 8 are in the form of a plurality of stacked plates which are piled upon each other. These plates are positioned at an angle between 0 and 90 degrees, but preferably 45 degrees, to the table, suitable clamping means being provided. A guide roller for pre-bending the strip may be provided. The pressure heads of the tools may comprise either fixed to rotatable wear resistant bodies such as balls or cylinders. The strip may be hot and cold-rolled steel strip or non- ferrous metals or plastics. The seams of the pipe may be formed by welding or, with the edges preferably overlapping, by means of adhesive. The machine may be used for making conical pipes.

Patent GB-208578-A (GB)
Title: Process for the manufacture of alkali carbonates
IPC: C01D7/00
Filed: 1922-09-13
Abstract: Alkali carbonates are obtained by treating an alkali compound such as sodium sulphate or an insoluble silicate such as feldspar with gases containing carbon monoxide with or without steam or inert gas at 400-900 DEG  C. and under reduced pressure. Accelerators such as ammonia, amines, or nitrogen oxides may be added to the gases in small quantities.  The reaction may be effected in a rotary furnace, the solid material entering at the end at which the gases leave. When treating sodium sulphate, the sulphur dioxide evolved should be withdrawn rapidly by suction or by continuous or intermittent admission of jets of steam or inert gas.  The sulphur dioxide may be oxidized to trioxide and used to convert alkali chloride into sulphate.  When feldspar is treated, the alkali carbonate is extracted from the treated material by lixiviation.  When water-gas is employed as the source of carbon monoxide, it may be enriched in carbon monoxide by adding a limited quantity of air to burn the hydrogen only.  The gases need not be free from carbon dioxide.  The Provisional Specification states that the reaction may be effected under pressure.  Reference has been directed by the Comptroller to Specifications 7355/85 and 4403/13.

Title: Method of and apparatus for separating oil from ballast water in tanks on board ship
IPC: B01D17/02
Filed: 1954-08-26
Abstract: 787,804. Gravity-separation apparatus: treating waste effluents. BINMORE, J. M. Aug. 18, 1955 [Aug. 26, 1954], No. 24828/54. Classes 46 and 111. [Also in Group XXXIII] A method of separating oil from ballast water in tanks on board ships comprises pumping oil and oil-contaminated water from the surface of the water in the tank until such surface is free or substantially free of oil, simultaneously aerating the mixture of the two liquids to facilitate separation thereof and subsequently separating the oil from the water. The apparatus comprises two buoyancy chambers 5, 6, designed to float such that the liquid surface AB is between them, and such that a suction pipe 10 coupled to the chambers 5, 6, dips into the liquid surface. The suction pipe 10 is fitted to slide freely within an encasing cylinder 11 fixed in a vertical position so that the chambers 5, 6, may rise and fall to maintain its level relative to the surface of the liquid. Under pumping action, the flow through the suction pipe is made to impinge on a disc 12 fastened to the upper end of the sliding suction pipe 10; this diverts the stream radially through 90 degrees, thus producing both a radial stream and a lifting force. This lifting force causes a withdrawal of the suction pipe 10 through the surface of the liquid and allows an ingress of air to the suction flow, which effects a lowering of the density of the stream, and hence a lessening of the lifting force, and automatically checks the rise of the suction box 5, 6. A stop bracket 13 is provided to prevent excessive rise of the sliding assembly. When operating in water with a thin film of oil on the surface, the suction stream will thus be composed of oil, water and air. The water, oil and air sucked from the tank are passed to an apparatus where they are separated. This comprises three superposed chambers 18, 20, 129 in the first of which the oil tends to flow upwards and is directed outwards by radial channels 25 in a disc 22. The reciprocal channels on the upper surface of the disc 22 permit run-off water above the disc to be guided between the upwardly ascending sectors of oil from beneath the disc 22. The second chamber 20 may have a disc 30 similar to the disc 22 to make the separation of the oil from the water more pronounced. In the third chamber 129 the separated mixture of oil and air passes over a heated coil 44 de-aerating the oil. The extracted oil passes up a pipe 34 to an oil receiver 37 from which it is run to a container and the separated water flows up a pipe 41 to a receiver 42 from which it is run off by a pipe 43.

Title: Improvements in artificial arms
IPC: A61F2/58
Filed: 1945-09-28
Abstract: 596,206. Artificial arms. OTTERMAN, J. Sept. 28, 1945, No. 25208. [Class 81 (ii)] An artificial arm comprises an operating member actuable by a flexion cord and a selector mechanism for coupling the operating member separately and independently either to an elbow joint for flexing the arm or to a driving member for a hand or other appliance. As shown the forearm structure 20 and the appliance drive shaft 15 are carried by a cylinder 23 rotating in trunnion bearings 24 formed on a flanged cup 26 which swivels inside the arm bucket 11. A pulley member 44, 45 rotatably mounted centrally on the cylinder may be turned by a cord 14 and restored to home position by a spring 49. A spring- pressed pawl 70 mounted on the pulley normally engages a slot in the cylinder 23 so that the forearm is flexed on pulling the cord 14. Downward movement of a lever 16 actuates a sliding cam 68, Fig. 3, which disengages the pawl 70 from the cylinder, and locks the cylinder against rotation by engaging a bolt mounted on a trunnion, Fig. 4, in one of many holes formed in the cylinder. A spider 75 inside the cylinder carries two ratchet wheels 81, 82 each provided with a bevel wheel 79, 80 meshing with a bevel wheel 74<1> on the drive shaft. Mounted on either side of the pulley member are spring-pressed pawls 83, 84 which can cooperate with the ratchet wheels, and two rocker members 90 linked by a bridge 91 and a pin 92 which fits under the tail 93 of the pawl 70. A fixed cam 100 depresses the rocker and holds both pawls 83, 84 disengaged near the home position of the pulley. Again, when pawl 70 engages the cylinder the fingers 94 on the rocker disengage both pawls 83, 84 so that the shaft cannot be rotated. When pawl 70 is disengaged the rocker lifts clear. Tappets 85, 86 mounted at right angles on the pulley member then maintain one or other of the pawls disengaged so that rotation of the pulley rotates the shaft in one or other direction. A spring-pressed trip pawl 97 and star wheel 87 rotate the tappets and reverse the pawls in engagement at the start of each rotation of the pulley. The trip pawl may be lifted clear by twisting the knob 101. The swivelling cup 26 may be retained in selected positions by a spring-pressed ball and socket device 36 or by a lever and notch device, Fig. 9. The appliance fitted at. the wrist may be rotated by a sleeve tube surrounding the drive shaft 15 and fitted with a mutilated gear co-operating with pegs mounted on one or both of the trunnion bearings as the forearm is flexed, Fig. 10. The Provisional Specification describes a modification in which rotation of the elbow joint is achieved by simultaneously engaging both the ratchet pawls and thus preventing rotation of the shaft. Specifications 133,344, [Class 81 (ii)], 596,209 and 596,212 are referred to.
