Abstract: 741,042. Mixing-appliances. JONES, G. L. R., and KESSEL, F. LLOYD-. Nov. 18, 1952 [Aug. 18, 1951], No. 19516/51. Class 86. [Also in Groups VI, XXIV, XXVI and XXXV] A stand 1, 4 is provided with alternative high and low speed drives 7, 8 on to which can be placed or suspended interchangeable domestic appliances such as a mincer, mixer, shredder, potato peeler &c. and has a further drive point 80 into which can be plugged a plain or flexible drive shaft for driving a brush or scrubber. These drives are coupled by gearing to a motor in a base on to which a column 2 of the stand is removably placed. Alternatively, the stand can be placed on the drive of the power wringer of a washing machine. The stand is provided with arcuate covers 91, 94 coupled together to be pulled over by a hand-grip 92 to cover in the top. The appliance is placed over the appropriate drive but does not become coupled to the drive until it is further moved such as by rotating its wedgeshaped body lugs 28, Fig. 10, under headed pins 30 thus forming a bayonet fastening whereby holes 19 in its rotary disc 16 receive spring-pressed drive pegs 20 in a disc 7 on a hollow spindle 12 geared at 15, 6 &c. to the main motor drive. Instead of the pins, the drive may be a squared socket to receive a square-ended shaft. The drive, gears &c. are enclosed in a casing mounted on the upright or column 2 and provided with a removable gear &c. cover 4. The casing 1 is also provided with means for suspending a mixer or beater, Fig. 9, therefrom to be driven from a driving ring 8 geared through 40 &c. to the main drive motor. Such suspending means comprises an opening 10 in the cover 4 through which the beater is lowered until its top ring 29, Fig. 9, rests on the edge 17 of the opening 10. Similar headed pins 30 forming a bayonet joint secure the beater in driving connection with 8, by means of spring-pressed pins 20 on 8 entering holes in the disc 35 of the beater. Fig. 9 shows the mixer similarly located in position by headed pin 30 over the drive ring 8, Fig. 3. One of the mixing spindles 58 carries a cone friction disc 64 engaged with the conical ring 65 of the drive ring 8, the other spindle 57 being driven therefrom by gears 61, 62. Instead of the cone clutch the ring 65 may have internal teeth to drive a smaller gear wheel on a stirrer shaft. Instead of the pin 20 and hook bayonet joint connection, the circular opening may have radial slots to receive wedge lugs, Fig. 10, projecting from the casing of the appliance, e.g. the stirrer.

According to the invention a mechanism comprising two parts is geared to the shafts 8, 12, the relative movement of the two parts being effective to operate a switch 33 associated with the motor 4. One part comprises a nut 23 driven from the shaft 8 by speed increasing gearing 21, 22, and the other part comprising a shaft 24 having a screwed part 24a engageable with nut 23. The shaft 24 is connected to the shaft 12 by reduction gearing 12a, 25 and is axially movable. The nut 23 is held against axial movement by a collar 23a. The screwed part 24a is urged towards the nut 23 by a spring 29. A coned portion 31 on the spindle 24 actuates the switch 33 and other switches 34 if desired. The end 32 of the spindle may operate a signal or serve as an indicator. Normally the parts. are as shown, the nut 23 and screw 24a being fully engaged with the switch 33 open. When the switch 1 is moved to the position desired coil 19 actuates switch 20: to energize the motor 4. Free wheel 6 drives shaft 8 to position selector members 9. 10, 11 and rotate collector 2. At the same time the nut 23 is rotated to move the shaft 24 axially to close the switch 33. The collector 2 eventually causes de-energization of the coil 19 and the switch 20 returns to the position shown. As the switch 33 is now closed the motor 4 is reversed and the free wheel 7 drives the shaft 12 to move the parts 16, 17, 18, to the pre-selected positions and the gearing 12a, 25 moves the screw 24a into the nut 23 so that the switch 33 is open when all the parts are in the desired position.

Abstract: 357,975. Distilling solid carbonaceous materials. NIELSEN, H. and LAING, B., York Mansion, Petty France, Westminster. June 28, 1930, No. 19718. [Classes 55 (i) and 55 (ii).] In the distillation of solid carbonaceous materials by contact with superheated steam, the latent heat of the steam is recovered from the mixture of steam and distillates by injecting the effluent liquor obtained from the process into the mixture and passing it through evaporators which use the heat from the spent distilling medium. The material is distilled in rotary retorts 1, which may be of the kind described in Specification 324,212, [Class 55 (i), Coking &c.], by contact with a large volume of superheated steam in the manner set forth in Specification 287,037, [Class 55 (i), Coking &c.]. The steam, heated in superheaters 2, is passed in counter current to the charge and passes together with the distillates through dust removers 5, 7 to a de-superheater 9 fed with hot effluent liquor circulated by a pump 10 and pipe 11. The steam and uncondensed distillates pass through an evaporator 12, and the condensed liquors and oils flow to an oil separator 16 from which the hot condensate liquor is forced by a pump 18 into the de-superheater 9, the surplus liquor passing by pipe 18a to the evaporator 12. The uncondensed steam and distillates pass through a condenser 21 and oil scrubber 31, and the remaining gases are fed by a pipe 32 to the furnace 33. Low pressure steam from the evaporator is led by a pipe 34 to a compresser 35 and by a pipe 36 to the superheater 2. The hot liquor from the condenser 21 is passed by a pipe 24 to an atmospheric condenser 25 where it is cooled and re-circulated through a pipe 29 to the condenser 21.

Abstract: 1489108 Preparing thermoplast-elastomer blends UNIROYAL Ltd 29 April 1976 [12 May 1975] 19793/75 Heading C3P Thermoplastic elastomeric blends are prepared by (1) mixing 90 to 10 parts by weight of a monoolefin copolymer rubber with 10 to 90 parts by weight of a polyolefin resin having hydrogen attached to tertiary carbon atoms and a free radical generating curing agent, (2) masticating and shearing the mixture to produce a semi-cure of the rubber, (3) completing the semi-cure of the rubber before the onset of melting of the polyolefin resin and (4) ensuring that once the polyolefin resin has melted the level of free radicals remaining in the mixture is not sufficient to cause substantial degradation of the polyolefin resin. The rubber may be an EP or EPDM rubber, and the preferred resin is polypropylene. The curing agent may be a peroxide having a ten hour half life temperature of less than 100 C. and/or a one hour half life temperature of less than 120 C., and preferably a ten hour half life of not less than 50 C., optionally together with an activator. Exhaustion of the free radicals may be ensured by restricting the proportion of curing agent and/or by adding a scavenger, e.g. conventional stabilizer or antioxidant, after the semi-cure of the rubber is complete but before the onset of melting of the polyolefin resin. The curing agent may be benzoyl peroxide, 1,1-bis-(tbutylperoxy) - 3,3,5 - trimethylcyclohexane, lauroyl peroxide or t-butyl perootoate. The scavenger may be pentaerythritol tetra-(3-(3,5- di - t - butyl - 4 - hydroxyphenyl)propionate) and dilauryl thiodipropionate.

Abstract: 147,881. Haurat, J. A., (Assignee of Greff, A. E.). Jan. 27, 1919, [Convention date]. Locks, revolving-barrel; lock-mechanism, masterkey.-Barrel locks with tumblers operated by axial insertion or by rotation of a key are constructed in series, each lock being operated by a master key or by a key that will not operate other locks in the series. Some of the locks of different series are also operable by a master key. Figs. 1 and 2 show a lock with a fixed casing 1 having opposing slots 2 and a rotary cylinder 3 having a central slot in which plate tumblers 5 are arranged, each tumbler being normally projected by a spring 6 into a slot 2 for locking, and provided with a slot 7 through which a key 8 is inserted to withdraw the tumblers into the cylinder 6, whereupon the key and cylinder can be turned to actuate a bolt by means of a lug 12 on the end flange 9 of the cylinder. The operative projections on the key of a given lock of a series act to withdraw the lower ends of the tumbler's flush with the cylinder and releases only that lock. The tumblers do not extend across the cylinder, and may be withdrawn further by a master key for the series. Additional similar tumblers 13 common to a screw may be interposed between the tumblers 5 for operation by projections on the other edge of the key. In a modification, one edge of the key may carry two side-by-side sets of projections operating two parallel sets of tumblers. In another modification, each of the tumblers 5, Fig. 5, formed with a cam surface 14 to project a divided spring plunger 16 so as to bring the division on the surface of the cylnder 3. The cam 14 is extended into a bearing surface 18 in some of the tumblers to suit the particular key. In a further modification, two sets of tumblers moved in opposite directions by a rotary key acts on two sets of spring-pressed divided pins in the manner shown in Fig. 5. The Specification as open to inspection under Sect. 91 (3) (a) describes another form, adapted for release by rotation of the key, in which the tumblers 19, 20, Fig. 8 (Cancelled), comprise pivoted spring-controlled levers provided respectively with a lug 21 and recess 22 which are engaged to release the locking-mechanism by rotation of the key 8. Or a rotary key may operate pivoted spring-controlled levers of the usual type. This subject-matter does not appear in the Specification as accepted.
