A combined I.C. engine carburetter throttle and automatic C.S.G. kickdown control for a motor-vehicle comprises a two-part lever 52, 58 jointly urged by the extended ends 68, 70 of a pre-loaded spring 66 into mutual engagement and pivoted about a common fulcrum pin 50 by an accelerator pedal 20 which engages an end 34 of one part 52 of the lever, the other end of the part 52 being connected by a cable 108 to the kickdown control lever 142, 144 on the C.S.G. 122, and the other part 58 of the lever being connected by another cable 76 with the engine throttle control lever 81, the movement of the throttle lever part 58 being limited by a fixed stop 96 situated in its path of angular movement for engagement therewith at the position corresponding to maximum throttle opening. A lost-motion connection between a cable bead 110 and a conical spring 106 on the kickdown cable 108 is absorbed at the position corresponding to the maximum throttle opening whereby further depression of the accelerator beyond maximum power setting, i.e. when the throttle lever part 58 is stationed against the stop 96, continues to pivot the lever part 52 to operate the kickdown control, which movement is resisted by the springs 66 and 106 and by a further spring 136 at the kickdown lever cable end (Fig. 1B), whereby the driver readily senses the increase in accelerator pedal effort indicating the kickdown position. This is graphically illustrated in Fig. 6 (not shown).

Filed: 1974-02-20
Abstract: 1451544 Reciprocating motors O'DELL MFG Inc 20 Feb 1974 [1 March 1973] 7662/74 Heading H2A A liquid pump comprises a non-magnetic axially extending liquid passage, spaced magnetizable members having confronting magnetic portions, at least one of which is a reciprocating pumping member within the passage and an assembly including means creating an alternating magnetic field having opposite flux polarities in each half-cycle which causes the said at least one member to move in the same direction during each half-cycle. The glass tube 24 passes through a laminated core having legs 14-20 and carries a toroidal coil 62 connected to an A.C. supply 66. Inside the tube, two iron pumping members 36, 50 are bonded to resilient soft rubber liners 48, 52 and are magnetized by the alternating flux field such that they attract in each half-cycle although each is alternately oppositely poled (Figs. 3, 5, not shown). The liners 48, 52 have protrusions 48a, 54a which are compressed when the members 36, 50 meet and thus provide stored restoring energy to separate the members when the flux field decreases. The liners 48, 52 are formed into seals 40, 46, 56, 58 at each end of the members 36, 50 which allow liquid to flow in only one direction (upwards). Thus as the members 36, 50 reciprocate, liquid is drawn from the source W into the chamber between the members when separated and is forced out through the outlet 30 when the members 36, 50 move together. A perforated stop 61 is provided at the inlet to prevent the members 36, 50 being lost when the pump is inoperative.

Title: An improved process for preparing metal sulphhydryl compounds from keratin degradation products
IPC: A61K38/01
Filed: 1937-03-17
Abstract: In the production of metal sulphydryl compounds of keratin degradation products, the keratin is hydrolyzed with dilute acids and the solution is freed from electrolytes by dialysis and evaporated to dryness or the acid is neutralized and the degradation product precipitated by an organic solvent; and the degradation product is reduced by sodium hydrosulphite in aqueous neutral or nearly neutral solution, a compound of a heavy metal such as gold, silver, copper, bismuth, antimony or arsenic being then added to saturate the sulphydryl groups.  More than one metal may be used.  Instead of sodium hydrosulphite, its derivatives such as formaldehyde sulphoxylate may be used.  Examples describe the production of the silver, copper, gold and antimony compounds.  Among the metal compounds employed to react with the reduced keratin degradation products are potassium auribromide, sodium antimonyl tartrate, phenylglycinamide-p-arsonic acid, 4-hydroxy-3-acetylaminophenyl arsonic acid, 2-hydroxy-4-acetylaminophenyl arsonic acid, and 4-hydroxy-3-aminophenyl arsonic acid.
