Abstract: 974,978. Windscreen wipers. GENERAL MOTORS Ltd. Dec. 5, 1963 [Dec. 12, 1962; Jan. 29, 1963], Nos. 46911/62 and 3617/63. Heading A4F. In a windscreen wiper mechanism the wiper drive motor 1 and a driven crank 16 or 17 on the end of a wiper pivots shaft 23 are respectively mounted forwardly and rearwardly of a partition 10 separating the front and passenger compartments of the vehicle, and the drive is transmitted by a pivoted lever member 7 connected by a link 6 to the motor drive crank 5 and by a link 14 or 15 to the driven crank 16 or 17, the link 6 extending through an opening 24 in the partition 10. The noise of the wiper motor in the passenger compartment is thereby made small, and is further reduced by covering the opening 24 with a rubber grommet 25 (not shown) through a slot in which the lever 6 passes. In two alternative embodiments the wiper motor is disposed at the side of the front compartment and the lever extends through the partition, the link being wholly within the front compartment.

Title: Improvements in or relating to the handling of slurries
IPC: B01J47/10
Filed: 1965-11-05
Abstract: <PICT:1102810/C1/1> A slurry of a granular solid and a liquid, e.g. a slurry of activated carbon for the purification of water in a supply tank 18 is fed to a receiving tank 19 via a chamber 10, the transfer of slurry from tank 18 to chamber 10 and from the chamber to the tank being controlled by valves 21, 23, 25, 27, 29 opened under the control of time switches 43 and 44.  The time switch 43 causes solenoid valves 31, 32 to connect the valve operating mechanisms of valves 21, 23 and 25 to a source of fluid under pressure and slurry is transferred from tank 18 to chamber 10, liquid flowing into tank 18 from pipe 20 and excess liquid flowing to an outlet through strainer 13 and pipe 24.  After the time set by the timer 43 has elapsed the operating mechanisms of the valves 21, 23 and 25 are connected to exhaust and an impulse is sent to time switch 44 which actuates solenoid valve 33 controlling the operating mechanisms of valves 27 and 29. Liquid is fed through pipe 26 to chamber 10 which discharges slurry to tank 19 until the level of slurry in chamber 10 is such that a photo-electric cell 17 is activated by a light source 16 through rectangular windows 14 and 15 in the chamber.  The cell 17 actuates a switch which causes the solenoid valve 33 to connect the operating mechanisms of valve 27 and 29 to exhaust and the transfer to tank 19 is stopped. After the time set by timer 44 has elapsed, a pulse is sent to a counter 45 which in turn may send a pulse to reactivate time switch 43 for the start a further cycle of operations.  The counter may be set to operate continuously or it may be associated with a control device set to provide a selected number of cycles of the device. The quantity of slurry transferred at each cycle may be adjusted by varying the vertical position of the light source 16 and cell 17.  A single solenoid valve may control valves 21, 23 and 25 or separate solenoid valves may be provided for each valve.  In a further embodiment, Fig. 2 (not shown), the light source (16) and cell (17) are placed on opposite sides of a transparent pipe between the base of the main chamber (10) and the connection (28) to the receiving tank.  To adjustably control the quantity of slurry fed to the main chamber (10) an extension (56) of the slurry supply pipe (22) is adjustably positioned in the chamber. The level of the lower end of the extension pipe (56) determines the upper level reached by the slurry.  In a third embodiment, Fig. 3 (not shown), the termination of slurry transfer from the main chamber (10) is produced by a ball float (60) which floats in the slurry but sinks in the liquid.  The ball blocks the outlet pipe (28) when substantially all the slurry has been transferred. A further pipe (61), having a strainer (63), provides a supply of liquid to the outlet pipe (28) for raising the float (60) to the top of main chamber (10) when foll of slurry. In a fourth embodiment, Fig. 4 (not shown), a valve-controlled liquid disposal pipe (91) is connected to the outlet of the main chamber via a strainer (63).

Title: New derivatives of heparin and processes for their preparation
IPC: C08B37/10
Filed: 1961-06-20
Abstract: A C1- 6 alkyl ester of heparin (claimed per se) is produced by esterifying a long-chain alkyl or aralkyl C9-27 quaternary ammonium salt, e.g. the "Hyamine 1622", "Hyamine 2389", "Cequartyl BE", "Arquad 2C", or "Zephirol" salt. Esterification may be effected with diazomethane. In the example, sodium heparinate and "Hyamine 1622" are interacted in aqueous solution to produce the acid hyamine salt which is reacted with diazomethane in methylene chloride to produce the methyl ester. After evaporation of the solvent, the ester is dissolved in butanol, extracted with aqueous potassium or sodium acetate, and precipitated as the potassium or sodium salt with ethanol.

Abstract: 1,160,978. Electric selectors. P. LUCAS. 24 Oct., 1966 [22 Oct., 1965; 10 Dec., 1955; 3 Aug., 1966], No. 47635/66. Heading H1L. In a cross-bar switch the contacts are controlled by members slidable between two stable positions by co-ordinate selecting bars of which the bars for one co-ordinate are in the form of rectangular strips pivoted about one edge, apertured to pass the associated members and carrying selecting fingers, each movable to obstruct the aperture. The selecting bar 7 shown comprises a strip 75 having its vertical edges flanged as shown. The bar pivots about the axis of the flange 76 and has spring-selecting fingers 78 mounted in the flange 76 and restrained for deflection in a plane parallel to the strip 75 by a slot 70 in the flange 73. The contacts at the cross-points are controlled by plungers 17 operated by rods 18 which project through apertures 77 in the bars 7. To close or open the contacts at a particular cross-point, the corresponding horizontal selection bar 8 is rotated to raise or lower projecting tongues 82. The tongues engage the ends of a row of selecting fingers 78, positioned just above or just below the tongues 82, and moves them into recesses 180 in the rods 18 of the plungers in that row. A vertical rod 7 can then be rotated to move the plunger the direction of rotation determining whether the contacts are opened or closed. In a modification (Fig. 3, not shown) the plunger incorporates a magnet which engages another magnet or an iron block in its end positions to increase its stability. In a further modification (Fig. 6) a plunger 91, 92 is carried on a spring block longitudinally compresses so that it is bowed to give stability through an over-centre action. A member 93 on the free end of the blade may operate the contacts.
