Title: Improvements relating to milking machines
IPC: A01D41/127
Filed: 1951-01-19
Abstract: 677,417. Cow milkers. HEMMENS PTY., A.V. Jan. 19, 1951 [Feb. 13, 1950], No. 1515/51. Class 84 [Also in Groups XXIX and XXXV] A milk metering apparatus consists of a measuring chamber 10 having an inlet 16 connected to a milk-collecting and de-aerating means 39 via a valve 18. Projecting from the chamber 10 into an emptying chamber 25 is a suction pipe 19 the bottom of which constitutes a seating for a float valve 20. A threaded emptying and calibrating tube 23 extends from near the bottom of chamber 10 into chamber 25. An internal pipe 27 extends from near the bottom of chamber 25 and its vertical continuation 29, which is connected to the suction line 30, contains a magnet 31 which may slide therein. A second magnet 33 is mounted on a counter-balanced lever 34 outside the tube 29 and near to the magnet 31, the lever operating between stops 38 being connected to a counting mechanism 36. Air vents 28, 16a may be fitted in chambers 25, 10 respectively. In operation, suction from the pipe 30 draws milk in through the inlet 16 until it is sufficient to close the lift valve 20, when the inflow stops and the valve 18 closes. The milk is now drawn through the tube 23 into the chamber 25 until the milk level falls below the inlet to tube 23 when the float valve 20 opens and the chamber 10 refills. The milk in chamber 25 is drawn through the pipes 27 and 29, lifts the magnet 31 so that the magnet 33 moves the counting mechanism 36, and passes into the suction line 30. A device for holding the vacuum should a teat cup fall off comprises a valve 52 within a housing 51. Air entering the housing causes the valve 52 to lift on to its seat 55 and thus the vacuum in the remainder of the apparatus is maintained. A leak port 57 in the valve 52 or its seat 55 provides sufficient suction for the teat cup to be replaced. The milk-collecting and deaerating means comprises a receptacle 39 having a milk inlet 40 and an outlet 41 which projects into a tube 49 perforated at its lower end which is in a sump 47. An outlet 43 and a pipe 44 connect the receptacle 39 to the suction line 30 either directly or through chamber 25. An air vent 46 is fitted and a shroud 45 prevents the milk passing into the outlet 43. A sample collector may be connected to a coupling 58 on pipe 30. A weighing bracket, a transport can with a cooling coil, or a gravity tank may be interposed between the pipes 29, 30 to calibrate the counting mechanism which may include an electrical warning signal and remote indicating means.

Filed: 1973-01-11
Abstract: 1348120 Penicillins F HOFFMANN-LA ROCHE & CO AG 11 Jan 1973 [12 Jan 1972] 1603/73 Headings C2A and C2C Novel penicillins having the general Formula (I) and salts thereof, wherein T is a C 2-5  alkyl group, R is a halogen atom or a C 1-6  alkyl, C 1-6  alkoxy, C 1-6  alkylamino, di(C 1-6  alkyl)- amino or C 1-6  alkanoylamido, and n is 0, 1 or 2, are prepared by N-acylating 6-aminopenicillanic acid (having the carboxyl group protected) with an acid of Formula (II) wherein T, R and n have the aforesaid meanings, or with an N-acylating functional derivative thereof, and cleaving off the carboxylprotecting group. The carboxyl group may be protected by salt-formation or esterification. Functional derivatives of the acid (II) are, e.g. halides, azides, anhydrides, reactive esters and active amides. When the acid itself is used, a condensing agent such as dicyclohexylcarbodiimide is preferably present. The reaction is usually performed in an inert solvent. The acids of Formula (II) above, which are said to be novel, are prepared by reacting an acid chloride of Formula (V) (e.g. o-methoxyphenylacetic acid chloride) obtained by treatment of the acid with thionyl chloride, with the benzyl ester of a compound (IV) (e.g. (R)-2-hydroxyisocaproic acid benzyl ester), T, R and n having the aforesaid meanings, to give an ester of Formula (III) (e.g. (R) - 2 - [(o - methoxyphenyl) - acetoxy]- isocaproic acid benzyl ester), in which B is a benzyl-protected carboxyl group, and then removing the protecting group by catalytic hydrogenation to give the desired acid (II). The latter is then converted to the corresponding acid chloride with thionyl chloride. The benzyl ester of (R)-2-hydroxyisocaproic acid is produced by reacting the said acid with benzyl chloride. (R,S) - 2 - [(p - Methoxyphenyl)acetoxy]valeric acid is prepared by reacting p-methoxyphenylacetic acid with 2-bromovaleric acid benzyl ester, and hydrogenating the product to remove the esterifying group. Pharmaceutical compositions with antibiotic activity against Gram-positive and -negative bacteria comprise a penicillin of Formula (I) hereinbefore or a salt or hydrate thereof, in association with a compatible pharmaceutical carrier.

Abstract: 1,261,040. Pulse generating circuits. NETWORK RESEARCH & MFG. CORP. 10 Jan., 1969 [12 Jan., 1968], No. 1682/69. Heading H3T. [Also in Division F1] The contacts for interrupting the current in an inductor are bridged by an SCR which is controlled by a timing circuit connected across the contacts. The period of interruption may thus be independant of the time the contacts are open. In the ignition system shown the opening of the contacts 14 allows a capacitor to charge through an inductor 28 until the gate voltage so provided causes the thyristor to break down. The energizing circuit for the ignition coil 13 is thus reclosed a predetermined time after interruption and before the contacts reclose. A transistor 42 may be connected in series with the ignition coil and a Zener diode 40 may clamp the voltage across the contacts and applied to the timing circuit.
