Abstract: 724,317. Cutting meat. ALEXANDERWERK AKT.-GES., and JAEGER, C. F. March 25, 1953. [March 25, 1952] No. 8298/53. Class 5 (1). [Also in Groups II, VI and XXIV] Meat put into a stationary spherical container 3 is cut, mixed and kneaded by rotating cutters 19 and at least one arcuate scraper 20 close to the container inside and mounted on a tool shaft 10. The scrapers may be of scoop like form at an angle to one another and extend as far as the space swept out by the cutters. A removable lid 27 with safety switch allows the tool shaft and tools to be lifted out as a unit after release from its end bearings. Release is done by pivoting up a latch 18 so that a handle 16 can be screwed out thus withdrawing a bearing pin 13 against the spring 14 from the roller bearing on the tool shaft. The other end of 10 is moved back from the square end drive 8 of the motor shaft 7. To empty the container it can be rotated to upside down position by a hand lever 24 after a spring- pressed pin 25 thereon is released from its locking notch 28. In Fig. 2 the scrapers are replaced by mixing arms 32 and the motor 4 drives through a gear box 33. In Fig. 4 (not shown) the container, consisting of 2 hemispheres clamped together, is overhung from the motor casing. In Fig. 5 change of speed is obtained by a stepped pulley 48 on the tool shaft 10 driven from friction roller 47 on the shaft of the motor 4, the motor being spring mounted at 49 to allow the friction roller to engage any step of the pulley. A hand lever 51 slides the stepped pulley along the shaft as required. An alternative change speed gear Fig. 6, is located between the motor 4 and the tool shaft 10 comprising friction lined wheels 53 and 59. The wheel 53 is moved up or down by handle 68 to engage either its annulus 58 or its boss 56 with a driven friction roller 47 the other side 57 of the boss engaging the boss 61 of the wheel 59. Alternatively, the motor 4 only may be moved down so that 47 drives 56, and 57 drives the annulus 62.

Abstract: 375,308. High tension switches. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION, WEDMORE, E. B., and WHITNEY, W. B. 36, Kingsway, London. March 18, 1931, No. 8331. [Class 38 (v).] Sparking, preventing.-In an A.C. gasblast switch with nozzle contacts as described in Specification 278,764, [Class 38 (v), Electric switches &c.], the contacts are so shaped that when the arc extending between the movable contact and the fixed contact in the region of the least gap tends to move from this region of maximum blast it experiences a restoring force produced by the electrodynamic action on it of the currents in the fixed contact. In the arrangement shown in the Figure, the nozzle contact 1 which has an outer enclosure is provided with a conical internal metal part 3a, screwed into its lower end. The lead-in to the contact is at 4 and the electrodynamic action of the current passing down the upper portion 1 tends to depress the arc drawn between the resilient movable contact 6 and the throat 3 of the nozzle. If, however, the arc impinges on the cone 2 the reaction between it and the upwardly flowing current in the cone lifts it to its original position. In a modification, the inner cone is dispensed with and the current led into the fixed contact both from the top and the bottom. The upper end of the nozzle may be furnished with a downwardly-extending cone so that when the arc impinges on it the direction of approach of the current through the contact is reversed to cause the arc to return. The nozzle and cone may be made up of segments or strips so that when the arc root settles on one of them the current is carried wholly by it and the electrodynamic action is concentrated and localized. Magnetic material may be arranged within the slits to increase the action. The nozzle 1 may be perforated to admit the gas blast to all parts of the arc.

Title: Improvements in or relating to the production of colourations or coloured effects on cellulose derivative materials
IPC: D06B1/02
Filed: 1930-03-15
Abstract: Cellulose esters or ethers, dyeing; unspecified types of dyes, dyeing with; printing.-Colourations or coloured pattern effects are produced upon textile materials made of or containing cellulose esters or ethers by applying to or removing from the materials colouring matters in volatilized form.  Thus  volatile colouring matters may be applied, uniformly or through a stencil, in a current of steam or other hot vapour or gas or may be applied uniformly or locally by the use of a transfer sheet subjected to heat and pressure, with or without a simultaneous embossing operation, as described in Specification 293,022, [Class 140, Waterproof &c. fabrics], Alternatively, the materials may be coloured uniformly or otherwise with a volatile colouring matter, whereafter a volatilization of the colour from selected portions of the material is effected by the local application, e.g. through a stencil, of a hot gas or vapour.  A current of steam carrying volatile colouring matter for application to the materials may be obtained by bubbling or injecting steam at sufficiently high temperature and pressure through a solution or suspension of the colouring matter, or by feeding such a solution or suspension to a steam spray jet.  Ombre effects may be obtained on fabrics by the use of a series of jets of steam or hot gas carrying volatile colouring matters graded as to their concentration or composition.  Specified volatile colouring matters are 4 - nitraniline --> p-xylidine, 2 - nitro- 4 - chloro-41-methyldiphenylamine, and 5-nitro-2-anisidine --> dimethylaniline or diethylaniline.  The invention is applicable for colouring mixed materials containing cellulose esters or ethers together with other fibres, such as cotton, silk, wool, regenerated cellulose, or flax, and in addition to fabrics, yarns, e.g. in the form of hanks, cops, or bobbins may be coloured.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application to textile materials in general. This subject-matter does not appear in the Specification as accepted.

Title: Preparation of olefine dibromides
Inventor: GUNKLER ALBERT ARTHUR
IPC: C07C17/02
Filed: 1956-03-19
Abstract: Olefine dibromides having 2 to 4 carbon atoms are prepared by forming a liquid solution of bromine and an olefine dibromide, e.g. by simply intermingling them, circulating a stream of this through an initial reaction zone and a cooling zone, feeding bromine to said solution at such a rate to maintain uncombined bromine therein, feeding olefine gas to the initial zone at a rate insufficient to consume all the bromine therein, whereby the gas is substantially consumed to form olefine dibromide, withdrawing a minor portion of the solution of bromine and olefine dibromide from the cooling zone, the major portion being preferably recirculated, and passing it to a final reaction zone, feeding olefine gas to this zone at a rate at least sufficient to consume all the bromine therein to form olefine dibromide, and withdrawing from this zone an olefine dibromide product substantially free of unreacted bromine.  Preferably, one or more intermediate reaction zones, functioning in the manner of the initial zone, are interposed between the initial and final zones and the unreacted gases from each zone except the initial one are preferably fed to the preceding zone.  The initial bromine feed may be liquid or vaporous bromine, or a solution of bromine in olefine dibromide.  The flow of liquid medium and the flow of gas in any zone may be concurrent or countercurrent.  The product may be purified by cooling, treating with soda ash and distilling. The temperature in the main reaction zone is preferably between 35 DEG  and 100 DEG  C. and advantageously the rate of feed of bromine to this zone corresponds to not more than 6 mol. per cent based on the composition of the liquid stream entering the zone.  The final zone is preferably operated between the same temperature limits and the concentration of bromine in the liquid stream of solution entering that zone is advantageously not more than 6 mol. per cent of that solution.  A suitable arrangement of apparatus is described with the aid of a drawing.  In an example, ethylene and bromine in ethylene dibromide give further quantities of ethylene dibromide.  Reference is also made to the use of propylene, 1-butylene and 2-butylene and mixtures thereof, to the use of bromine containing other substances such as organic bromides and to the use of dilute olefine gases containing other substances, e.g. methane, ethane, nitrogen or hydrogen, and it is stated that the process is usually conducted in the presence of a trace of water.

Abstract: 787,660. Bobbin supporting means for creels. PLESSEY & CO., Ltd. Feb. 13, 1956 [March 25, 1955], No. 8707/55. Addition to 732,137. Class 120(2) A bobbin supporting device for suspending bobbins in creels comprises a tubular sleeve 1 having supporting means at one end for attachment to the creel, bobbin supporting members (levers 3) carried by and adjacent the opposite end of sleeve 1, a spindle 9 mounted within the bore of the sleeve 1, a collar 21 surmounting the sleeve 1, slidable axially along the sleeve and connected to the spindle 9 in a relatively rotatable manner, means above and below this connecting means for imparting angular motion to the springle 9 as a result of axial two-way movement of the collar to permit movement of the supporting levers 3 into and out of their bobbin supporting position. In the embodiment shown the connection between the collar 21 and the spindle 9 consists of pins 22 engaging an annular groove 10 in the spindle the pins 22 sliding in slots 23 in sleeve 1. In operation, to release a bobbin from the supported position shown it is first pushed upwards in consequence of which the collar 21 is raised. This causes cam surfaces 14 on spindle 9 to engage pin 20 protruding from inside of sleeve 1 which results in rotation of the spindle 9. On downward movement of the collar 21 and spindle 9 lower cam surfaces 15 on the spindle engages with a further pin 24 on the sleeve 1 rotating the spindle 9 still further until pin 24 engages in one of the shorter splines 13 thus limiting downward movement of the spindle 9 and allowing the levers 3 to collapse into a slot 25 at the end of the spindle and so release the bobbin. In applying a new bobbin the collar 21 is again moved upwards, the spindle 9 again rotated such that the pin 24 now engages one of the longer splines 12. This permits the spindle 9 to move further downwards such that the levers 3 are prevented from collapsing by the periphery of the spindle 9 and the bobbin 26 is supported.
