Title: Elongate structural member
IPC: E04B2/78
Filed: 1975-06-20
Abstract: 1478589 Structural elements H STAEGER 20 June 1975 [27 June 1974] 26335/75 Heading E1K [Also in Division F2]  In portable building structures or internal structures for buildings &c of the kind wherein a structural element of elongate, preferably extruded, form, e.g. a column 1, has one or more longitudinal grooves 2 each undercut to form walls 4 on either side of an opening 3 through which a hook formation 15 on the end of a pivoted lever 12 may extend, the lever is mounted in a U shaped insert 11 fitted in a hollow end portion of another structural member 7, and is located by a pin 13 and pivoted, against the bias of a spring 14, by a screw 8 to swing the hook formation 15 so that it engages behind one of the walls 4 and clamps the member 7 in abutment with the outer surface of the member 1, the walls 4 having deformable, e.g. resilient, projections 5 which are engaged by the formation 15 to ensure tightness of the joint between member 7 and member 1. The insert 11 has projections 16 which engage a channel 17 in the bottom of the groove 2 to locate the member 7 relative to the member 1. The deformable projections 5 may be either as shown in Fig. 6 or may be shaped as saw teeth (5a, Fig. 5, not shown) so that they offer greater resistance to release movement of the lever 12 than to its tightening movement. Instead of a single lever 12, a pair of levers may be used so that their projections 15 move in opposite directions to simultaneously grip both walls 4 of a groove 2. Either pairs of projections 5 or single projections may be provided on each wall 4. Various alternatives to the octagonal column 1 of Fig. 2 are disclosed, e.g. a hexagonal or part-hexagonal column (Figs. 7-9, not shown), various panels, panel connectors (Figs. 10-16) and a complex column, Fig. 17, having three centre cores 24. In the panel shown in Fig. 11, only one end has a groove 2, the other end having a slot 22. Various hollow passageways 19 (20) 23 may be provided in the various panels or panel connectors to form double-walled panels or a part double-walled panel including a single-wall section 21. In the corner panel connector of Fig. 15, additional grooves 2a face laterally inwardly.

Abstract: 331,746. Maschinenfabrik Augsburg- Niirnberg Akt.-Ges. Oct. 22, 1928, [Convention date]. Electric and magnetic; disc.-In a device for braking the paper rolls of rotary printing- machines, the rotating part of a laminated plate brake is arranged on a shaft coupled with the spindle on which the paper roll is mounted, or on a stub axle carrying the paper roll, and the non- rotating part of the brake is adapted to be displaced in an axial direction by means of a braking magnet for the purpose of effecting the braking action. In the arrangement shown in Fig. 2, the gear wheel 6, receiving positive rotation from the web roll, drives through a gear wheel 12 the clutch disc of a laminated plate clutch 28. The armature 17 of the brake magnet 14 and the movable part 15 of the laminated plate clutch are mounted upon a shaft 13. Bv means of a switch current is supplied to the brake magnet 14 simultaneously with the stopping of the machine, the armature 17 is attracted, and the movable part 15 of the laminated plate clutch is pressed against the stationary part 18, the latter being held by pins 19. The intensity of the braking action is adjusted automatically according to the speed of the web roll bv means of a centrifugal regulator which controls resistances mounted on the clutch disc 28, and independently of the speed by manually adjusting a regulating resistance. The braking current is supplied to this regulating resistance by slip rings 21 mounted on the gear wheel 12. In a modification the braking arrangement is formed at the end of the roll spindle itself.

The taste of a sweetening agent comprising saccharin, sodium saccharin, sodium cyclamate or calcium cyclamate, or a mixture thereof, is improved by dissolving the agent in water, at a temperature not exeeding the boiling point of the solution, treating the solution with sodium chloride and one or more than one physiologically tolerated, i.e. non-toxic alkaline salt of a strong base and a weak acid, e.g. sodium bicarbonate and/or sodium glutamate, heating and/or boiling the resulting solution to bring about chemical reaction and the formation of a precipitate, then, if necessary, rapidly cooling the solution to room temperature or a temperature between 0 and -20‹ C., to promote precipitation, and finally separating the precipitate containing unwanted bitter substances from the solution, as by filtration. The separated solution may be concentrated until the improved sweetening agent crystallizes out. The amount of alkaline salt or salts used, is preferably less than the weight of sweetening agent in solution.

Title: Improvements in centre weft stop motions
IPC: D03D51/00
Filed: 1921-10-13
Abstract: 196,000. Hudson, J. H. Oct. 13, 1921. Stop-motions, weft.-The centre fork or stopping- motion peg 2, Figs. 2, 4 and 5, of usual construction is raised and lowered by means of a slide 6 provided with. an adjustable spring 17 and operated by means of a connecting-rod 7 passing freely through a pivotal pin 8 of a bush 9, an adjustable block 11 on the rod carrying a leaf spring or springs 12 provided with a friction pad 13 of leather &c. The rod 7 has thus lost motion in both directions. When the lay moves towards the warp beam, the connecting-rod 7 pulls the slide to the right and the usual cam part on the slide immediately raises the fingers 1 to allow a clear path for the shuttle. A stop 15 on the slide comes into contact with a bracket and during the further movement of the lay towards the warp beam, the rod 7 slides through the bush 9 against the friction of the pad 13. When the lav moves towards the cloth beam, the rod 7 pushes the slide to the left and the spring 17 causes the weft fingers 1 to be depressed. If the weft is present, a snug 19 on the fork is prevented from engaging a notch in the slide 6, which is moved to the left until a stop 16 engages a fixed part. The end 22, Fig. 8, of a rod 20 connected to the slide is thereby moved so far to the left as to miss a bent finger 23 when the lay continues its forward movement towards the cloth beam. During this continued forward movement the rod 7 slides through the bush 9. If the weft has failed, the snug 19 engages the notch in the slide 6 and arrests further movement thereof, the rod 20 consequently operating the finger 23 against the action of a spring 24. By means of an arm 25, the finger then operates a pivoted bracket 27 whereby the hand starting-lever 33 is actuated to stop the loom. To allow for the starting pick, the lever 33 can be moved into a corner 40, a collar 32 on a bracket on the lever then engaging an adjustable stop 34 on a rod 31 connected to a collar 30 on the finger 23, which is thus moved to a position out of the path of the finger 22, thus pre venting stoppage on the first pick.

As shown, an alternating- current ammeter of the moving-vane type has auxiliary polepieces 14, 15 provided with short-circuited coils 16, the arrangement being such that as the frequency increases the total flux decreases but the torque-producing flux is increased owing to the increased reluctance of the shunt flux path. Damping is effected by a vane 27 movable across symmetrically disposed poles 25 of a permanent magnet.

Latex, treating. - Pure rubber sheats are obtained from purified latex by electrophoretic precipitation upon an anode. The latex is preferably purified by centrifuging at the highest possible speed that does not cause coagulation and removing a very thin layer of the concentrated latex from the centrifuge. Organic dyes and other colloidal additional substances having a negative charge in the hydrosol state may be added to the latex before centrifuging and precipitated with the rubber. The anode upon which the rubber is precipitated preferably consists of a revolving drum or endless band of metal (e.g. amalgamated zinc) from which the sheet is stripped after leaving the latex bath. Fig. 2 shows one form of apparatus comprising a trough b containing the cathode k and an endless band a constituting the anode. The newly-formed sheet e is washed by means of sprays h and passed over a drying table i before being removed from the anode.
