Title: Improvements in or relating to electro-magnetic devices for reproducing sound from records
IPC: H04R11/08
Filed: 1928-08-10
Abstract: 320,981. Brown, S. G. Aug. 10, 1928. Gramophone pick-ups; magnetic instruments. - In an electromagnetic gramophone pick-up of the type in which a movable part oscillates between magnetic members, the moving part or armature carrying the needle is a permanent magnet. The armature. A is pivotally carried between a knife edge E, bearing in a V- shaped groove, and a rubber block F. both mounted on extensions B<1> of the cores of the coils C. The armature carries a block of rubber G at its upper end to damp its movement and to prevent contact with extensions B of the cores. The pick-up may occupy a space no larger than lin. by ¥in. by ¢in., and may be mounted by a stirrup onto a tone arm or equivalent member which is suitably weighted and the pick-up may be resiliently urged towards the record by springs.

[Also in Division F4] A fold-away cooking unit comprises a heating unit 1 having a plurality of gas burners and mounted directly on a flap 2 which is pivotably secured by two L-shaped brackets 3 and pivot pins 4 to side walls 6 of an enclosure 7. A cooking utensil retainer frame 9 is carried by support arms 10 and 11, the arms 10 being pivotably connected to the side walls 6 by pivot pins 12 and the arms 11 being pivotably connected to a limb 14 of a toggle comprising a further limb 15. The limbs 14 and 15 are connected at the mid point to one end of a toggle link 16, the opposite end of which is pivotably connected by a pivot pin 17 to the walls 6. When the cooker is in use, the heating unit 1 is lowered into a horizontal position when the flap 2 bears against abutments 5. When the cooker is not in use, the flap is pivoted into a vertical position where it is retained by engagement of a flange 18 of a hinged top part 19 of the enclosure 7 over an edge 20 of the flap 2. In an alternative embodiment (Figs. 2 and 3, not shown) a heating unit (21) is provided with a grilller on its underside, and is spaced from the flap 2.

Title: Method of manufacturing wheels

Abstract: 511,649. Annealing. DIXON, M. G. (Carnegie-Illinois Steel Corporation). Aug. 5. 1938, No. 23194. [Class 72] [Also in Group XXII] A wrought steel wheel is formed by mechanically deforming a blank at temperatures above the "thermal critical range" (900‹ to 1200‹C.), cooling down to temperatures above the martensite forming temperature (400‹C.) heating above "critical range " (800‹-850‹C.), cooling, and before any part of the wheel has reached the martensite forming temperature, its temperature is equalized and maintained between 450‹ and 600‹C. until complete alteration of austenitic to ferrite structure other than martensite is completed, whereupon the work is cooled slowly say by about 50‹C. per hour. A round ingot is produced by rolling or casting and after cutting into blanks is cooled. A blank heated to about 1200‹C. is shaped to the form 1a, Fig. 2, with dies 2, 3 and to the form 1b, Fig. 3, with dies 2a, 3a. A punch 6, Fig. 4, pierces the hub and the work is again heated to about 1200‹C. and acted on by rolls, 8, 9, 10, 11, Fig. 5. A coning press Fig. 8 bends the web, which may have been previously pierced with holes. The work is now cooled until the heavier parts have passed the "critical range" but is reheated before any part has reached the martensite forming temperature (about 400‹C. After reheating to slightly above the "critical range" the wheel is cooled, reheated slowly, and cooled slowly as described above.

Abstract: 1,224,750. Multiplex pulse code signalling. WESTERN ELECTRIC CO. Inc. 16 May, 1968 [22 May, 1967 (2)], No. 23219/68. Heading H4L. Interconnected control centres in time division multiplex communication systems are maintained in synchronism by a phase comparison of the respective synchronizing signals. The signal transmitted between centres consists of a plurality of minor frames each with its own frame synchronizing signal repeating at a frequency of 8 kc/s., which together form a major frame with a sync. signal repeating at 40 c/s., the transmission delay being adjusted to be an integral multiple of the 8 kc/s. frame sync. signal interval. The major frame sync. pulses of the incoming signal are used for the phase comparison. As shown in Fig. 5, time division multiplex signals including data and television signals from a remote centre B are supplied via highway 500 to a separation circuit 501 which passes the television signals to a decoder 505, the data signals to respective phase synchronization circuits 503 and the 40 c/s. frame sync. signal to a frame detector 502. The outgoing signal to centre B includes the major frame sync. signal generated at 520 and supplied via multiplexer 525, a television signal from coder 521 and data signals. Frame detector 502 recognises the sync. pattern, includes means for adjusting the arrival time to the nearest minor frame interval and supplies a signal indicating the demarcation between successive major frames to a phase comparator 201B which also receives a pulse once per major frame in the time slot, bit and phase at which demarcation between successive minor frames occurs at the local centre, from a divider 510 under the control of the oscillator 204. This signal is derived from the 8 kc/s. minor frame signal provided by counter 205 and also controls the sync. generator 520. The minor framing signal is also supplied to phase comparators provided for incoming signals from other remote centres. The error signal at the output of comparator 201B is combined with the error signals from the other comparators, including that for information from the local centre including only the minor frame sync. signal received at 550, in an averaging circuit 202 which applies weighting to compensate for different distances between centres and after filtering is used to correct the frequency of the oscillator 204.

Abstract: An oil-soluble basic nitrogen-containing graft polymer is made by polymerizing a basic nitrogen-containing monomer with a hydrocarbon polymer formed by the copolymerization of a C2-C6 aliphatic mono-olefin and a vinylidene aromatic hydrocarbon.  Basic monomers specified are dialkylaminoalkyl acrylates, methacrylates, fumarates, maleates citraconates and mesaconates, vinyl pyridines N-vinyl pyrollidone and piperidone, and N-methylol acrylamide and methacrylamide.  The preferred hydrocarbon polymers are copolymers of isobutene with styrene, alpha-methyl styrene and its m-isopropyl and p-isopropyl derivatives, and vinyl naphthalene.

Alternatively the hydrocarbon polymer may be dissolved in a solvent and ozone passed through the solution, followed by polymerization of the basic monomer in the solution of ozonized polymer; or a mixture of the hydrocarbon polymer and basic monomer may be subjected to severe physical working.  The examples describe the following processes:  (1) polymerizing dimethylaminoethyl methacrylate in a xylene solution of an isobutene/styrene copolymer with the aid of t-butyl peroxide; (2) as in (1) but using an isobutene p-isopropyl-alpha-methyl styrene hydrocarbon polymer; (3) polymerizing beta - diethylaminoethyl methacrylate in an ozonized heptane solution of an isobutene/ styrene copolymer; and (4) working in a ball mill a cyclohexane solution of an isobutenestyrene copolymer and beta-diethylaminoethyl methacrylate.  The resulting graft polymers are used as additives to lubricating oils.  The Specification describes also the copolymerization of isobutene and p-isopropyl-alpha-methyl styrene with a boron trifluoride catalyst.ALSO:A lubricating composition comprises a mineral or synthetic lubricating oil and a viscosity index and detergency improving amount of a graft polymer obtained by polymerizing a basic nitrogen containing monomer with a copolymer of a C2-C6 aliphatic mono-olefin and a vinylidene aromatic hydrocarbon, e.g. graft polymers of dimethylaminoethyl methacrylate with isobutene/styrene and isobutene/p-isopropyl-alpha-methyl styrene copolymers, and beta-diethyl-aminoethyl methacrylate with isobutene/styrene copolymers.
