Abstract: 1,001,447. Oil burners. BIRMINGHAM SMALL ARMS CO. Ltd. Feb. 13, 1964 [Feb. 22, 1963], No. 7151/63. Headings F4F and F4T. An oil burner of the wall-flame kind has fuel projected on to a surface, a portion of which has been previously heated by a heating device and a sparking device. A shaft 20 carrying a disc 9 and vanes 10, is rotated by a rotor 21 mounted in a stator 22, to draw fuel from a well 4 and pass it through tubes 7, 8 which spray the oil mixed with air drawn through adjustable ports 24, on to a surface formed by loosely connected, heat resistant, metallic alloy plates 11 each provided with a hood 12. An electrical coil 17 is attached to one plate 11 and an igniter rod 13 is mounted in a porcelain housing 14 with its tip 16 spaced from a plate 11 just above the upper limit of the oil strike, the coil being downstream of the rod 13 in the direction of rotation of disc 9. The coil can be heated simultaneously with, or independently of, the spark discharge from rod 13. Oil supply to well 4 from an external source is controlled by a valve 6.

Title: New penicillin compound and its production
Inventor: BRANDL ERNST
IPC: C07D499/46
Filed: 1955-03-11
Abstract: A penicillin compound stable to acids and therefore suitable for oral administration is p-cresoxymethyl penicillin and which is produced by growing a penicillin producing mould in association with a culture medium and a precursor compound represented by the formula CH3C6H4-O-CH2-R1 where CH3C6H4-O-CH2- is the p-cresoxymethyl radical and R1 represents a carboxylic acid group or functional derivative thereof such as a carboxy, carboxyester, carboxy salt or carboxyamide group; a carbinol; carbinylamine; acetal; or aldehyde group, acidifying the clarified culture medium with a mineral acid to approximately pH2.1, extracting the acidified material with a water-immiscible organic penicillin solvent, e.g. chloroform, butyl acetate or amyl acetate and recovering the p-cresoxymethyl penicillin acid from the organic solvent extract.  In the example, the sodium salt is produced by dissolving crude p-cresoxymethyl penicillin in aqueous sodium hydroxide.  The potassium salt is produced by extracting a chloroform extract of a fermentation broth with an aqueous buffer at pH 2.1, treating the buffer with butyl acetate and the butyl acetate extract with potassium acetate in butanol.  The free acid is obtained by adding a mineral acid such as hydrocarbon to a solution of an alkali metal salt of p-cresoxymethyl penicillin. Specification 643,514 and U.S.A. Specification 2,562,410 are referred to.ALSO:Para cresoxymethyl penicillin acid (see Group IV(b)), which is stable in an acid medium, is administered orally in the form of a tablet, capsule, aqueous suspension or oleaginous suspension.

Filed: 1973-02-15
Abstract: 1418132 Chain-saws ANDREAS STIHL MASCHINENFABRIK 15 Feb 1973 [15 Feb 1972 13 May 1972] 7382/73 Heading B5L [Also in Division F2] In a chain-saw the chain, which passes around a sprocket 9 is driven from a motor via an output shaft 8, a safety clutch 9 which once disengaged remains so under the influence of centrifugal force until the motor speed drops and a centrifugally operated clutch with shoes 19 which move out to engage a drum 13 rotationally fixed to the sprocket 9 under the influence of centrifugal force. The embodiment of the safety clutch illustrated in Figs. 2 to 4 comprises a driving member 23 fixed to shaft 8 and driving, by engagement with axial protrusions comprising a cam member 40 and a member 30 (see Fig. 2) an annular oval disc 29, which disc has also a radially inward projection 33 which engages in a gap 36 between axially projecting portions 35 of rotor 17 of the centrifugal clutch 10 to drive this clutch, and so the sprocket 9. On engagement with an abutment of the cam portion 40 of member 31 when the clutch 12 is to be disengaged the disc 29 is moved perpendicular to the axis of shaft 8 against a spring 38 to disengage portion 33 from between projections 35. When this occurs the centre of gravity 39 of disc 29 is moved such that the clutch will remain disengaged if centrifugal force acting on disc 29 is sufficient to hold it against spring 38. Other embodiments are described either similar to that shown in Figs. 2 to 4 (see Figs. 5, 6, 7, and Figs. 17 to 25, not shown) or with one or more pivoting pawls having counterweights to hold them disengaged. One of the latter type is illustrated in Fig. 13, the pawl 29c assuming the role of the disc 93 described and being sprung (spring 38c) to engage in ratchet slots 36c in the axially projecting part of the rotor of the centrifugal clutch (Fig. 12, not shown). Disengagement is effected by engagement of the end 40c of the pawl with an abutment. The abutment for opening clutch 12 may be moved to cause this upon operation of a chain brake of the chain saw. Provision may also be made to prevent the clutch 12 reengaging until a member which acts on the pawl or disc to disengage the clutch on striking an abutment is moved back to its initial by a further abutment (Figs. 17 to 27, not shown). The clutch may also be engaged and disengageable in both directions of rotation.

In a superheterodyne radio receiver having at least one reflex stage for amplifying two or all of the radio, intermediate and audio frequencies negative feed-back is provided by means of an impedance appropriate to the frequency fed back to the reflexed stage, connected in the cathode circuit. In Fig. 1, valve 3 acts as a cathode follower R.F. stage and as an amplifier for reflexed intermediate frequency. The R.F. oscillations are fed to the grid through the tuned circuit of transformer 9 which has negligible impedance at radio frequencies. The circuit 6, which possesses rejector resonance at signal frequency and acceptor resonance at image frequency as described in Specification 670,851, is connected in the cathode circuit. The output from circuit 6 is fed to the grid of frequency changer valve 8. The intermediate frequency produced by this valve is coupled by tuned transformer 9 to the grid of valve 3, the impedance of transformer 2 being negligible at intermediate frequency. The secondary winding of the transformer connected in the cathode circuit of valve 3, is tuned to intermediate frequency and connected to a further amplifying or detecting valve 10. Fig. 2 shows an R.F. stage valve 11 with reflexed audio frequency fed back from audio amplifier valve 16 via transformer 17 and across condenser 18. The audio output is taken from transformer 19.

A chuck-like wrench comprises a handle 13, and a tubular closer member 20 pinned to the handle at 23 and terminating in an open end 24 which surrounds the inner end of a cylindrical array of elongate jaws 30 which terminate in spaced jaw faces 33 and are surrounded by a cylindrical actuator 40. When the actuator 40 is placed over a nut and pressure applied to the handle 13, the closer 20 moves against spring pressure and carries with it the jaws 30. As the jaws thus move downward through the actuator 40, camming surfaces within the latter close the jaws to grip the nut. Relative rotation between the jaws 30 and the handle 13 is prevented by projections 25 engaging between the jaws 30. Each jaw is provided with a shaped end 35 (Fig. 2, not shown) furnishing a shoulder 34 against which the face of the nut abuts. In a modification (Fig. 7, not shown), the handle is furnished with an archimedean screw engaged by a ratchet-operated reversible drive means.
