Abstract: 311,222. Pierce, H. May 7, 1928, [Convention date]. Fats and fatty oils, extracting by solvents.- In apparatus for dry cleaning fabrics a plurality of units is operated by a single prime mover and means are provided for automatically stopping each unit independently of the others at the end of a predetermined interval. Each unit comprises a cylinder 24 mounted in a casing 1, and supported and driven by discs 30, 31 which engage V-shaped grooves 29 in the cylinder. The driving shafts 32, 33 of the units are directly coupled. A timing device is connected with means for raising the cylinder from the driving discs which comprises discs 45 which engage the grooves 29, and are raised by a spring 46 through levers 40, 42. The timing device also releases a sliding door 3 which is opened by a spring 10. The timing device comprises a rack 65 which normally engages a pinion 94 but which can be released by the operator and set in a predetermined vertical position according to graduations on the casing 59. A pivot 78, Fig, 14, carries a latch 80 which engages the door 3, a latch 83 which engages a bar 74 connected to the lever 40, and an arm carrying a sliding block 86. The closing of the door 3 releases the latch 83, and allows the lever 40 to be depressed by the pedal 41, lowering the cylinder on to the driving discs, the bar being held down by the latch 83 as shown in Fig. 14. The pinion 94 is actuated through two ratchet mechanisms 103, 114, Fig. 7, by a rod 112 eccentrically pivoted on the cylinder. A lug 71 on the rack moves the block 86 into the path of a lug 90 on the cylinder whereby the latches 80, 83 are released, the door 3 being. opened and the cylinder raised from the driving discs into engagement with brake blocks 38.

An automatic adjusting device for telescopic members 1, 2, comprises a friction member 6 interposed between a piston 1 and a pin 4, the friction member 6 being movable axially relative to both of them, to and from a retracted position. The friction member 6 engages the piston 1 and has its axial movement, relative to the pin 4, in both directions, limited by stops 5, 8, resilient means 9 acting on member 6 to urge it against one of the stops 5 limiting its axial movement to the retracted position. The pin 4 is secured in the closed end of a cylinder 2 and possesses a reduced portion around which the friction member 6 in the form of a spring is mounted. A spring washer 9 comprises the resilient means. When wear has taken place in a disc brake, actuated by the telescopic members, then in application of the brake the friction member 6 moves with piston 1 against washer 9 until the reaction of washer 9 overcomes the frictional force between member 6 and piston 1. On retraction of piston 1, the friction member 6 remains in its adjusted position. In further embodiments described, the friction member may comprise an inwardlyflanged sleeve, Figs. 2, 4 (not shown), or an annular block, Fig. 3 (not shown), the resilient means including a helical compression spring.

Patent GB-934682-A (GB)
Title: Improvements in or relating to a method for making detergent compositions
IPC: C11D11/04
Filed: 1960-11-03
Abstract: Detergent compositions are produced by reacting in solution in a liquid or liquefied polyalkylene glycol, preferably a polyethylene glycol, one or more detergent acids, e.g. dodecylbenzene sulphonic acid, with potassium or, preferably, sodium hydroxide to neutralize all or substantially all of the acid or acids.  It is preferable to use the alkali in powder, pellet or flake form, any solid unreacted alkali being removed by mechanical means, and to utilize the heat evolved on neutralization to help maintain the glycol in the liquid state. When substantially all of the acid has been neutralized the neutralization may be completed with an alkaline builder, e.g. trisodium phosphate.  Higher fatty acids, e.g. stearic or lauric acid, may be included in the solution in the polyalkylene glycol and neutralized by the use of additional sodium or potassium hydroxide over that required to neutralize the detergent acid. The detergent compositions preferably contain 5 to 50% by weight of polyalkylene glycol and one or more additives, for example foam boosters and stabilizers, e.g. lauric acid isopropanolamide and myristic acid monoethanolamide; inorganic fillers, e.g. sodium sulphate; water softeners, e.g. sodium tripolyphosphate and sodium hexametaphosphate; sterilizing agents, bactericides and bacteriostats, e.g. o-phenyl phenol, chlorhexidine salts, and 3,5,31,41-tetrachlorosalicylanilide. Bars are produced by allowing the liquid composition to cool and set in suitable moulds.ALSO:Detergent compositions are produced by reacting in solution in a liquid or liquified polyalkylene glycol, preferably a polyethylene glycol, one or more detergent acids with potassium or, preferably, sodium hydroxide to neutralise all or substantially all of the acid or acids.  It is preferable to use the alkali in powder, pellet or flake form, the solid unreacted alkali being removed by mechanical means, and to utilize the heat evolved on neutralisation to help maintain the glycol in the liquid state.
