Abstract: 1,221,445. Agricultural implements. MASCHINENFABRIK FAHR A.G. 8 Oct., 1968 [20 Oct., 1967], No. 47579/68. Heading A1F. [Also in Division F2] An implement comprising a beam which carries tools and may be swung between an extended position perpendicular to the direction of travel and a folded position is characterized in that the two driving shafts 4, 5 extending co-axially through the beams 1, 2 in the extended position are connected by a dog clutch near the hinge 3 and that a friction clutch 7 is engageable to bring about the torquetransmitting condition after the dog clutch is engaged. The beam carrier 1 and beam 2 are hinged at 3 and shafts 4, 5 are journalled inside them respectively. Mounted on the end of shaft 4 is dog clutch half 6 which can move axially with the shaft and one end of the clutch is connected with the friction clutch 7 which is keyed to shaft 4 via rotary part 8. A coaxial compression spring 10 extends round this half and pin 11 attached to shaft 5 fits into recess portion 9 on the end of dog clutch half 6. The pin abuts against the spring causing the frictional faces of clutch 7 to engage. The beam is held in the extended position by dog catch 12 which is pressed against the face 16 of projection 14 by spring 13. When the beam hits an obstacle the dog 12 disengages allowing pin 11 to slip out of the recess 9 and the spring 10 to expand thus causing clutch 7 to disengage, the tools to stop, and the beam 2 to swing backwards. By reversing the tractor the beam 2 swings back to the extended position and the dog to re-engage on projection 14. The tools may be rotary scythe mowers or hay turners or tedders.

A dishwashing machine comprises a chamber 1 for a liquid additive 2 to be supplied to water in the machine via an opening 3 closable by an electromagnet 6, and a receptacle 12 for a powder additive 13 to be supplied to water in the machine via an opening closable by a lid 12 having a latch 9 actuated by the electromagnet 6. The powder additive 13 is first dispensed by the closing by a programme control device of a switch 12 to energize the electromagnet 6 to release the latch 9 to open the lid 11. As soon as the lid 11 opens as switch 15 opens to de-energize the electromagnet 6 so that no substantial flow of liquid additive is released through the opening 3. At a later stage in the washing cycle the electromagnet 6 is energized by closure of a switch 18 for a period long enough to dispense the desired quantity of liquid additive.

Title: Improvements in or relating to the preparation of bacitracin metal methane sulfinates
IPC: A23K20/195
Filed: 1965-11-19
Abstract: The invention relates to bacitracin metal methane sulphinates, and to their preparation. The water-soluble sulphinates are prepared by reacting, in aqueous solution, bacitracin and a water-soluble metal formaldehyde sulphoxylate, in a mole-ratio of 1:1 to 15, and if required, separating the resulting methane sulphinate from the solution.  The water-insoluble sulphinates are prepared by reacting, in aqueous solution, a soluble bacitracin metal methane sulphinate, prepared by the above method, and a soluble salt of the required metal, to give a precipitate of the insoluble metal methane sulphinate.  Soluble bacitracin metal derivatives are those of alkali metals and calcium; insoluble derivatives include those of zinc and manganese.  The reactions may be effected at room temperatures or, if required, with heating; separation of soluble derivatives from solution may be by drying or freeze drying. The inventive compounds are useful for any purposes where bacitracin itself might be employed, such as in animal feeds (see Divisions A5-A6), and are said to be less toxic for parenteral administration than the parent antibiotic.ALSO:Bacitracin metal methane sulphinates are employed, together with a nutrient or ingestible diluent, in animal feeds, or in solution or suspension in water or saline for parenteral administration the antibiotically active ingredients, which are novel (see Division C2), may be prepared, when water-soluble, by reacting a soluble metal formaldehyde sulphoxylate with bacitracin in aqueous solution to give a solution of the required sulphinate: the preferred metal being sodium, or else K, Mg, or Ca.  The solution may be employed as such, when suitably rendered isotonic (e.g. with NaCl), for parenteral administration, or may be dried or freeze dried and the solid derivative made into conventional pharmaceutical forms. Water-insoluble derivatives, such as zinc or manganese methane sulphinate derivatives of bacitracin, prepared by reacting, in aqueous solution, the said soluble metal derivatives with a soluble zinc or manganese salt to give a precipitate of the corresponding bacitracin derivative.  Nutrient carriers for animal feed supplement compositions may be soy flour, wheat middlings, or corn meal, and extra Vitamin B12 may be added.

Patent GB-497275-A (GB)
Abstract: 497,275. Automatic control systems. WALLACE & TIERNAN PRODUCTS, Inc. June 15, 1937, No. 16611. Convention date, June 27, 1936. [Class 38 (iv)] [Also in Group XL] Concentration.-In purifying liquid by filtration or sedimentation, a change in the clarity of the effluent changes the rate of flow of the liquid. The effluent is scanned photo-electrically and the electric current changes induced by changes in clarity change the flow of liquid. A portion of the effluent may be passed through a sampling chamber 14 into which a beam of light from a source 20 passes, light reflected from solid particles in the liquid falling upon a photo-electric cell 22 which is connected in series with a battery 26 and a resistance 27. This voltage across the resistance 27 is impressed on the control grid of a screen grid amplifier tube 25. A condenser 30 connected across the plate circuit is charged by a battery 31 when contacts 32 are closed and discharges through the tube when these contacts are open at a rate dependent upon the voltage on the control grid which depends upon the illumination of the cell 22. The condenser 30 is also connected across the grid circuit of the relay tube 33 so that this grid is maintained below cut-off potential until the charge has entirely leaked away. When this has happened, a relay 35 is energized. The contacts of the relay 35 co-operate with cam-controlled contacts 48 to determine the movements of a reversible motor 36 which adjusts a valve 13 controlling the fluid flow rate and is shown as a shading coil induction motor. Cams 50, 51 may cause switch 32 to be opened for one minute during the first half of which contacts 48, 43 remain closed, contacts 48, 46 being closed during the second half minute. The direction and duration of running of the motor 36 thus depends on the conductivity of the amplifier 25 which depends upon the clarity of the fluid and the resulting conductivity of the photo-cell 22. Adjustment to a desired clarity may be effected by variation of the grid bias of the tube 25 by potentiometer 60, of resistance 27 or of plate voltage 31.
