Title: Improvements in or relating to machine milking installations
Inventor: STROM SVEN OLOF ERIK
IPC: A01J5/04
Filed: 1971-04-29
Abstract: 1275529 Machine milking installation ALFA-LAVAL AB 29 April 1971 [8 May 1970] 12256/71 Heading AIM A machine milking installation comprises a row of milking stalls 1 moveable along a closed path 3; each stall having a teat cup cluster and a milk receiving vessel 4. On one part of the path, forming an arc of a circle, milk is transferred from each milk receiving vessel to a milk collection station 8. As each stall moves around the arcuate section, the inlet pipe 14 of the collection station, which is pivotable about the centre 13 of the section, moves with it; nozzles 11, 12 from the stall's milk outlet pipe 10, and inlet pipe 14 being sealingly engaged. Sensing means 23, 27 actuated respectively by a strut 9 on the stall as it enters the arcuate section and by inlet pipe 14 as it reaches the end of the section, provide signals to operate piston 17. The piston acting via arms 21, 22 swings the inlet pipe into engagement with the stall and returns it when transfer is complete. As long as the nozzles are in engagement sensing means 25 is actuated by contact with outlet pipe 10 to open the valves permitting milk transfer, when pipe 14 is swung back at the end of the arcuate section the sensing means is disengaged and the valves are closed. A branch pipeline on the collecting station may be provided for diverting defective milk to waste.

Title: Improvements in and relating to electronic trigger circuit arrangements employing transistors
IPC: H03K19/084
Filed: 1962-03-30
Abstract: 963,159. Transistor two-state trigger circuits. SOCIETE DE DIFFUSION D'EQUIPEMENTS ELECTRONIQUES, S.D.E.E. March 30, 1962 [March 30, 1961], No. 12270/62. Heading H3T. A two-state trigger circuit comprising two alternatively conducting transistors, changes its state in response to a signal and remains in that state or returns to the original state at the end of the signal in dependence upon the condition of a control signal applied through a diode to one base electrode. The circuit shown has a normal state in which transistor T1 is conducting, being switched to the state on first applying the power by a capacitor C5, as described in Specification 915,762. The circuit may be switched to the other state by varying the voltage at terminal 7 as by connecting it to the positive supply source terminal 10 by switch I2 directly or through a resistor X. The circuit will return to its initial state on removal of this voltage, unless terminal 8 has been connected to a suitable potential source, as by operating switch I1 to connect the terminal directly or through a resistor to the positive terminal 10. Outputs for operation of further stages may be obtained from terminals 1-4 and 12-15 and the common emitter resistor R1 may be decoupled by a capacitor common to other circuits. A diode D1 isolates output terminals 12-15 from the base of transistor T1 when T2 is non-conducting. A suitable input circuit arrangement is described with reference to Fig. 2 (not shown).

Title: Improvements in or relating to steering mechanism for motor road vehicles
IPC: B62D7/22
Filed: 1927-05-07
Abstract: 295,307. Graseby, R. C. May 7, 1927. Hydraulic and pneumatic transmission for a motor vehicle having hand-operated steering gear with a lost-motion connection 5, 6 between the drop arm 3 and the drag link 4 comprises, in combination, power operating means, a first lever 9 operatively connected thereto and to the drag link, and a second lever 15 pivoted at 14 on the first lever adapted to operate the valves 16, 17 controlling the admission of fluid to the operating means and to be connected without lost-motion to the steering means, e.g. to the bottom of the drop arm. The lost-motion connection allows the desired valve to be operated before the hand gear acts on the drag link, the latter being moved by the power gear until it catches up to the handgear and thus shuts off the power again. The first lever 9 is pivoted at 10 and is connected by a link 23 to the drag link 4. The second lever is connected by pivoted links 18, 22 to a pin 5 on the drop arm 3, the link 22 having a lost-motion connection 19 with the drag link. The valves and power cylinder 12 are so arranged that when one end of the cylinder is open to the power supply the other is open to the atmosphere. Power may be obtained from the engine induction pipe or from a reduced-pressure pump or a compressor driven by the engine. When the engine is not running the cylinder 12 is arranged to be open to the atmosphere.

Abstract: A soluble oil composition, suitable for cutting oil emulsions, comprises 30 to 80 wt. per cent of a lubricating oil, 5 to 40 wt. per cent of a salt of a sulphonic or soap carboxylic acid, or mixtures thereof, as an oil-in-water emulsifier, a sulphurized hydrocarbon or sulphurized fatty oil, and a zinc, barium, calcium or magnesium salt of an alkyl or cyclo-alkyl dithiophosphoric acid wherein the alkyl or cyclo-alkyl groups have from 4 to 12 carbon atoms.  The lubricating oil may be a refined or unrefined paraffinic or naphthenic mineral oil, a synthetic hydrocarbon oil, e.g. from the Fischer-Tropsch synthesis or olefin polymerization, or a blend of two or more such oils, having a viscosity of from 50 SUS/100 DEG  F. to 600 SUS/210 DEG  F.  Suitable emulsifiers are the alkali metal salts of petroleum and alkaryl sulphonic acids, fatty acids, and resin acids, e.g. tall oil and rosin.  A preferred emulsifier comprises a mixture of a potassium soap of rosin or tall oil with a sodium petroleum or alkaryl sulphonate of average molecular weight from 420 to 440. Materials suitable for sulphurization include olefins such as di-isobutylene, petroleum oil fractions, lard oil and sperm oil containing 10 to 40 wt. per cent sulphur.  The sulphurized materials are present in the composition in amounts between 5 and 35 wt. per cent, depending on the sulphur content, to provide at least 2 per cent total sulphur.  The preferred dithiophosphates are the zinc dialkyl or dicycloalkyl dithiophosphates wherein the alkyl or cycloalkyl groups are hexyl, cyclohexyl, octyl, decyl, dodecyl, 2-ethyl hexyl, 2,4,4-trimethyl pentyl, 2,4,4,6,6-pentamethyl heptyl, or mixtures thereof.  Optional ingredients are pH adjusting agents such as triethanolamine, caustic alkali or oleic acid and coupling agents such as diethylene glycol.  The compositions are emulsified with from 70 to 95 per cent of water.  Examples comprise a light refined mineral oil; sodium petroleum sulphonate mixed with a potassium soap of tall oil or sodium alkaryl sulphonate mixed with a potassium soap of resin acids; sulphurized sperm oil with or without sulphurized di-isobutylene or lard oil; zinc dihexyl dithiophosphate; and triethanolamine.

Abstract: 902,174. Sewing; sewing - machines. UNITED STATES TRUST CO. OF NEW YORK. April 13, 1961, No. 13305/61. Class 112. [Also in Group VIII] The edges of the toe opening of a circularly knitted hose are closed in abutting relationship by a stitched seam comprising two needle threads anchored by a single looper thread. As shown, a transverse seam 17, formed on a twoneedle overedge sewing machine, joins the instep portion 14 to the top of the toe portion 16. The hose is formed with a gusset 23 between the foot portion 13 and the toe portion 16. It is stated that the additional fabric thus provided at the bottom of the toe opposite the toe opening, allows the edges of the toe opening to be brought together and joined without the formation of puckers at the end of the seam. To indicate the position of the seam, the courses of fabric knitted subsequent to the knitting of the seam line are knit of a yarn of contrasting colour or contrasting texture. Alternatively, the same yarn may be used and the subsequent courses differentiated by the insertion of tuck stitches therein. The surplus fabric is cut away during the scanning operation. The needle threads 33 and 34 are concentrated by a looper thread 35, and the supply of thread is so proportioned that the seam can lie flat with its edges 14a, 16a in abutting relation. It is stated that said abutting relation may alternatively be achieved by using elastic thread for the needles. The lines of stitching traverse adjacent courses 37, 38 and 40, 41 respectively. The needles are staggered and each wale of knitting is thus secured by at least three stitches.
