Title: Electric hair curlers
IPC: A45D2/36
Filed: 1971-10-29
Abstract: 1338954 Electrically heated hair curlers TEXAS INSTRUMENTS Inc 19 April 1971 [27 Jan 1970] 20402/71 Heading A4V [Also in Division H5] An electrically heated device comprises an element, composed of a conductive-filled crystalline polymer having a positive temperature coefficient of resistance above an anomaly point, which acts both as a self-regulating heater and as a heat storing means. The illustrated example is a hair curler which has a cylindrical outer shell 12 with a plurality of fingers 14 extending outwards therefrom. The element 22 is a hollow cylindrical moulding which may be made of a polyolefin filled with carbon black and has a conducting coating on its inner and outer faces. These coatings may be of electroless nickel or electroplated tin. A cylindrical sleeve 24 which may be of copper is pressed into the bore of the element and is in electrical contact with the pin 28 by the member 26 which may be formed integrally with sleeve 24. The outer face of the element is surrounded by a conducting sleeve 32 which is bent over at 34 to enclose pin 44. To increase the electrical contact the space between the plate 42 and base 34 may be filled with solder or the plate may be connected electrically to the conducting rim 38. Annulus 40 is made of an insulating material. In use the hair curler is heated electrically. Below the crystalline melting point of the polymer the resistance is constant but once the crystalline structure is broken down the resistance of the element increases, which effectively limits the current when the operating temperature is reached obviating the need for thermostatic control. The heat storing capabilities of the element are enhanced by the latent heat associated with the phase change from the crystalline to the amorphous polymer.

Patent GB-358116-A (GB)
Title: A new or improved explosive and its method of manufacture
IPC: C06B25/34
Filed: 1930-07-05
Abstract: Explosive products are obtained from raw albuminoid materials such as glue, bones, hides, hair, feathers, and others by treating the material with a mixture of sulphuric and nitric acids, separating the product of this treatment, and subjecting it to a second treatment with a mixture of sulphuric and nitric acid containing a greater proportion of nitric acid than the first mixture.  For example, 100 kg. of common glue are treated with a mixture of 360 kg. of concentrated sulphuric acid of 66 B<\>ae and 270 kg. of nitric acid of 36 B<\>ae; the resultant oil floating on the surface is separated; and this oil is treated with a mixture of concentrated fuming sulphuric acid and 260 kg. of concentrated nitric acid of 36 B<\>ae. The process is carried out at normal temperatures of say about 15-25 DEG  C., and in no case above 40 DEG  C.

Abstract: 1276835 Meter reading and identification UNITED GAS INDUSTRIES Ltd 25 July 1969 [30 April 1968] 20473/68 Heading G4H A coding device for generating signals indicative of the identity of a gas, electric &c. meter with which it is associated comprises two groups of electrical conductors which are selectively interconnected to form a code pattern whereby when a temporary scanning connection to each of the conductors of one group is made in turn, the conductors of the other group are electrically read for each such temporary connection. As described the meter comprises four rotating wipers the movable contacts of which are connected respectively to the four terminals L, M, N and P. The ten fixed contacts of each of the wipers are connected in common to the lines 0-9 so that by scanning the terminals L-P and reading the terminals 0-9 an electrical read out indicative of the reading of the meter will be obtained. The coding arrangement consists of terminals A-H which are interconnected with the terminals 0-9 as shown at 26. The interconnections may be formed by a matrix code board having its columns connected respectively to terminals A-H and its rows to terminals 0-9, connections being provided by conductive pins at selected row-column intersections. Alternatively a rotary wiper may be provided for each terminal A-H with ten fixed contacts connected to terminals 0-9. Thus by positioning the wipers the desired interconnections between the two sets of terminals may be provided. Coded read out signals are received at the terminals 0-9 when the coding terminals A-H are scanned.

In a three-phase induction watt hour meter comprising a laminated and slotted armature disc and three driving systems each consisting of a voltage winding and a current winding disposed symmetrically about the axis of the disc and acting thereon, there are provided in order to compensate for errors due to the stray flux from the current coil, extension pieces of ferromagnetic material from the core of the current coil, one from each pole of each core, the extensions of one polarity lying in a plane parallel to the armature disc and the other extensions lying in a second plane parallel thereto, with a further homogeneous conducting disc mounted on the armature shaft and interposed between the planes defined by the extension pieces. In order to reduce the eddy current linkage between the driving systems I, II, III the armature disc 12, shown in plan view in Fig. 2 comprises a plurality of thin radially-slotted aluminium discs which are stuck together one on top of the other with layers of insulation between successive discs and the slots being regularly offset in relation to each other from one disc to the next. The cores of the current coils are mounted beneath the disc 12 and have solid iron pole plates 21, 22 attached to each pole of the core. Ferromagnetic extension pieces 25, 26 are riveted to the polepieces 21, 22, brass rivets being used and a brass plate being inserted in between each polepiece and its corresponding ferromagnetic extension.

Abstract: 168,742. Petermann, A. July 13, 1920. Lathes.-In a lathe for turning bar-stock of the type in which the bar is gripped in a hollow spindle rotating in poppets b<1>, b, Fig. 3, by a chuck operated by an axially moving collar c, the movements of the latter are effected by a cam sleeve f', which is intermittently driven by a pulley h through a friction clutch. The poppets b<1>, b are carried by a base-plate b<2>, which is moved along the bed by a cam. The collar c is engaged by segments carried by the forked arm c<3> of a bell-crank lever, the other arm c<5> of which engages a lever d, pivoted at d<1> to the base-plate b<2> and carrying a pin e engaging cams f<2>, f<3> on the sleeve f<1>. The cams f<2>, f<3> can be spaced at different distances, and are for closing and opening the chuck respectively. A disc g Figs. 9 and 10, mounted on the sleeve f<1> has inclined recesses, up which rollers g<2> tend to ride and engage the disc g with a ring g<2> in a flange on the pulley h. The rollers are held in recesses in a ring k having a projection k<1>, which ordinarily engages a lever l and so prevents the rollers from jamming. The lever l is tripped, to effect rotation of the sleeve f<1>, by projections on a cam disc i, which engage a lever m mounted on the spindle of the lever l. The cam i is mounted on a rotating shaft f on which the cam sleeve f<1> is loosely mounted. In a modification the rollers are replaced by an eccentric which is ordinarily held out of engagement by the lever l. When the lever is tripped the eccentric is turned by a spring and jams the clutch.
