Abstract: 1,046,264. Electric analogue calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 16, 1964 [May 30, 1963], No. 21631/63. Heading G4G. A differential amplifier comprises two similar conductivity type (e.g. NPN) transistors T1, T2; the collector of T1 being connected to the base of T2 and to a load resistor R3, the emitter of T2 being connected to the base of T1 through a potentiometric resistor network R1, and R2 capacitance connected to earth; the emitter of T1 being biased over resistor R4; and the collector of T2 being coupled to an input terminal O/P by load resistor R5. Input voltages e1, e2 from sources of similar impedance Rs are applied to terminals 1, 2 connected respectively to the base of T1, and over capacitance C1 to the emitter of T1. It is shown by mathematics that if R1 = R3 and R4 = R1 the input impedances at terminals 1, 2 are equal and the output current at the collector of T2 is proportional to the difference between input voltages e1 and e2.

Abstract: 579,589. Mine chocks. CHARLTON, T. S., and DUNSTONE, D. Q. Nov. 6, 1944, No. 21707. [Class 20 (ii)] [Also in Groups XXV and XXXIV] Mine chocks incorporate a pair of wedges with a parallel interposed member so that the wedges may move separately or together. Telescoping cylindrical members with enlarged ends 10, 11 for bearing against timber &c. have slots to pass the wedges 12, 13 and taper abutments 16. 17 for them. They are separated by a strip 18 with ends extending into the slots and sides 19 to act as a clip on the wedge 13. The shorter wedge 12 has side flanges 22 that prevent it from passing entirely through the slots and the wedge 13 has upstanding projections to limit the movement of the wedge 12. Rims 23 in the outer chock engage slots in the inner to prevent relative rotation. Two sets of chocks may be united by a non-bearing distance bar and in this case the wedges move in planes at an angle to the bar.

Abstract: 589,142. Sound-producing toys. GOWLAND, J. P. Nov. 6, 1944, No. 21776. [Class 132 (iii)] In a toy, a hollow simulacrum 10 (Fig. 1) conceals a concertina type sound producing device 13 (Fig. 3) employing a weighted bellows and rotatably mounted within the simulacrum, the device being rotated by means of a rotatable drive wheel 23 or the like which engages the surface on which the toy runs. The simulacrum is mounted on a baseboard 11 provided with freerunning wheels 12 or slide runners so that it may be drawn or pushed along. The soundproducing device 13 is mounted in a disc 14 by means of clips 16 which have projecting pins 18 rotatably supported in brackets 19 upstanding from the baseboard. A further pair of brackets 26 depending from the baseboard, which may be combined with the upstanding brackets 19 both being formed from strip metal, receive the axle of the drive wheel 23 and an intermediate roller 22 in contact with the disc 14 which protrudes through a slot in the baseboard. The slots in both brackets are vertically elongated to ensure a friction drive from the ground surface to the disc 14 and driving parts may be suitably covered, for example with rubber. The disc 14 may alternatively be rotated by direct contact with the ground or be driven from one of the running wheels or the toy may be fitted with a conventional clockwork drive, in which case the disc 14 may be rotated by clockwork also. The toy may be constructed chiefly from wood and the simulacrum which may itself support the sound-producing device and running wheels, may be moulded in a suitable material.

Abstract: 1,048,402. Multiplex radio signalling. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. May 24, 1965 [July 31, 1964], No. 21948/65. Heading H4L. In an arrangement for providing common amplification of at least two modulated carriers of different frequencies and different required output energies, e.g. television sound and vision carriers, the video carrier is applied to terminal 17 and the audio carrier to terminal 18 of a 3 db. coupler 19, the input carrier energies at terminals 17 and 18 being 20 and 40 watts respectively.

Title: Improvements in and relating to control systems for dynamo-electric machines
IPC: H02P1/24
Filed: 1922-01-27
Abstract: 187,928. North, N. E., and Metropolitan-Vickers Electrical Co., Ltd. Jan. 27, 1922. Controllers with continually interchanging resistances.- Relates to motor controllers of the kind in which sections of resistance 1, Fig. 1, are connected to segments of a continually-revolving or oscillating structure resembling a commutator 3, and the amount of resistance included in the motor circuit is varied by varying the separation of brushes 4, 5 in contact with the commutator. According to the invention, power-operated mechanism moves one brush relatively to the other. In one construction, Fig. 2, a stationary commutator 3 is traversed by brushes 4, 5 carried on arms 14, 15 which are continually revolved at the same rate by a pilot-motor 25 through a spur wheel 17. In order to reduce the effective resistance the leading arm 14 is clutched to a previously idle wheel 23 having fewer teeth than the wheel 17. In a modification, similar gearing revolves the commutator and the brushes are stationary until the idle wheel is clutched in. The resistances are in the form of blades, mounted in the revolving structure so as to constitute a ventilating fan. The controller may be arranged to work automatically as shown in Fig. 4, in which the closure of a master switch 55 closes a line switch 52 to the main motor 48, starts the pilot-motor 25, and actuates the clutch through an electromagnet 63. A short-circuiting switch 53 is arranged to be closed when the brushes meet, the pilot-motor being simultaneously stopped, and the brushes separated by a spring. In another arrangement the brushes are held together by an electromagnetically controlled latch. For three-phase supply, four brushes may be used, two being connected to one of the phases. The pilot-motor may be arranged to have its field excitation and consequently speed of cutting out resistance dependent on the line current.

Abstract: Glycol mono-ethers having the general formula <FORM:0808880/IV (b)/1> wherein R represents an aliphatic, isocyclic or heterocyclic radical, R1 represents hydrogen or an aliphatic, isocyclic or heterocyclic radical, or R and R1 together with their common carbon atom form a cyclic nucleus, and R11 represents an aliphatic, isocyclic or heterocyclic radical are prepared by reacting an aldehyde or ketone R-CO-R with a chloromethyl ether Cl-CH2 -O-R11 and magnesium in a medium of tetrahydrofuran, tetrahydropyran or a homologue of either, hydrolysing under non-acidic conditions the magnesium compound formed, and isolating the resulting glycol ether.  The glycol ethers yield aldehydes <FORM:0808880/IV (b)/2> on treatment with an acid such as sulphuric, oxalic, formic or p-toluene sulphonic acid.  In an example, some chloromethyl ethyl ether in tetrahydrofuran solution is added to a mixture of magnesium in dry tetrahydrofuran containing a little mercuric chloride; then the remainder of the chloromethyl ethyl ether solution and a solution of amyl methyl ketone in tetrahydrofuran are jointly added dropwise with cooling; the reacted mixture is decomposed by a cold saturated solution of ammonium chloride and worked up to recover the resulting 1 - ethoxy - 2 - methyl - 2 - heptanol which is converted into 2-methyl heptanal by treatment with formic acid.  In like manner, chloromethyl ethyl ether is reacted with acetone, methyl ethyl ketone, methyl isobutyl ketone, methyl isobutenyl ketone, methyl heptenone, acetophenone, benzyl methyl ketone, benzylidene acetone, isopropyl acetophenone, b -ionone, p-isopropyl benzyl methyl ketone, diisobutyl ketone, cyclopropyl phenyl ketone, benzophenone, cyclohexanone, heptanal, acrolein, crotonal, pentene-2-al, benzaldehyde, veratraldehyde and piperonal, and chloromethyl methyl ether is reacted with methyl isobutyl ketone and ethyl butyl ketone and boiling points for the resulting ethers are given.

Abstract: 1,123,492. Winding layouts for dynamoelectric machines. NATIONAL RESEARCH DEVELOPMENT CORP. 4 May, 1967 [18 May, 1966], No. 22194/66. Heading H2A. In order that a three-speed, pole-changing induction motor may have one speed in which all the stator copper is in use, two pole-changing windings are provided, at least one employing pole-amplitude modulation, and one of the alternative pole-numbers of each winding being the same so that they can act together either in series or parallel. If both windings are pole-changing by pole-amplitude modulation, they may both be of wide ratio, e.g. 16-pole/6-pole and 16-pole/2-pole respectively. If one employs the conventional Dahlander method, it must naturally be in the ratio 2:1. In this case the pole-numbers could be 16-pole/ 4-pole and 16-pole/8-pole. The use of two windings acting simultaneously serves to reduce harmonics since these will be different in the two windings.
