Title: Improvements in or relating to compensated induction motors for single or polyphase alternating current
IPC: H02K17/28
Filed: 1924-04-05
Abstract: 213,928. Deutsche Werke Akt.-Ges. April 6, 1923, [Convention date]. Alternating-current commutator machines. - A compensated single or polyphase induction motor comprises a primary winding a, Fig. 1, and an auxiliary winding c on the stator, a squirrel-cage winding g, a, secondary winding b provided with short-circuiting contacts n, and a commutator winding d on the rotor, the commutator winding being connected through brushes with the auxiliary winding c; the squirrel-cage winding, which is dimensioned for starting purposes only, damps the current in the short-circuited commutator coils at starting and so tends to diminish sparking. The switches f, m, n for the various windings are preferably operated in sequence by a single switch device, and safety fuses may be combined therewith. In a modincation, a switch of the controller type is employed. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter. The secondary winding b, Fig. 2 (Cancelled), may be permanently short-circuited, or closed directly or through slip rings and an external resistance e when the primary a is connected to the line so that at starting the voltage is darnped. As shown in Fig. 7 (Cancelled), the auxiliary winding c and the squirrelcage winding g are placed on the stator and the main winding a on the rotor, the winding b not being employed. By suitable design of the winding g, a special starter may be dispensed with. The switching devices may be mounted together on the motor casing. This subject-matter does. not appear in the Specification as accepted.

Title: Improvements in and relating to wet spinning
IPC: B01J19/16
Filed: 1961-03-09
Abstract: <PICT:0916206/IV(a)/1> Filamentary material is made by wet-spinning a solution of a polymeric material, especially a vinylidene cyanide polymer, into a heated coagulant containing a volatile component whilst floating on the surface of the coagulant a normally solid paraffin hydrocarbon which is an immiscible non-solvent for the coagulant, is a liquid at the spinning temperature, has a specific gravity lower than that of the coagulant, and a flash point higher than the spinning temperature.  Suitably the paraffin wax used has a specific gravity of 0,890-0,910, a melting point of 104 DEG -130 DEG F., and a flash point higher than 350 DEG F.  The spinning of a solution of a vinylidene cyanide:vinyl acetate copolymer in a mixture of acetonitrile and water into an aqueous coagulant is exemplified. Apparatus as shown comprises a tank 1, filled with coagulant 2 and covered with a paraffin hydrocarbon layer 3. Hollow cylinders 4 extending through the cover layer provide for an overflow 5 and a fibre exit 6.  The cylinder used for the latter purpose may be omitted when the cover layer does not exceed 1/8 inch thickness. Spinning solution is fed from container 7 to spinneret 8 and the filaments formed are withdrawn over the godets shown.  The cover layer minimises the loss of volatile solvents from the coagulant and can be easily removed after spinning by allowing the coagulant to cool until the cover layer solidifies.  Specification 681,120 is referred to.

Abstract: 1405456 Automatic frequency control; measuring time intervals KENT INSTRUMENTS Ltd 22 Feb 1973 [24 Feb 1972] 8643/72 Headings H3A and H3H A sampling control circuit for controlling the frequency at which an input signal is sampled by apparatus 9 comprises : means 15 providing a preset signal representative of a desired output from the sampler 9; a comparator 16 for comparing the actual and desired signals to produce a difference signal; frequency correction means 17, 18 fed with the difference signal and with a signal dependent on the sampling frequency ; and a signal generator 20, 21 supplied with the output from the frequency correction means so as to produce an output signal which is fed to the sampler 9 to adjust the sampling frequency. In an arrangement for measuring changes in fluid flow through a tube, or speed of movement of a strip, input signals are applied to a crosseorrelator 8 in which they are sampled and processed to produce a signal on line 11 which is representative of a number D in binary coded form. The number D is a function of the time delay T between the signals on lines 12, 13 and also of the sampling rate R and is compared with a desired value signal in subtractor 16. The output from subtractor 16 may be linearized by processor 17 and the result is fed to ADDER/ SUBTRACTOR 18 together with a signal n from store 19 representative of the sampling rate. The output from unit 18 is used to update the number stored in store 19, which is applied to a display unit 27, and also to control the multiplication factor of a multiplier 20. The multiplier 20 is also fed with clock pulses from source 21, to produce at output 25, the control signal for sampler 9.

Abstract: 805,755. Electrodeposition of antimony. HARSHAW CHEMICAL CO. March 25, 1955, No. 8733/55. Class 41. To produce a strongly adherent fine texture electroplating of antimony, especially on lead, copper, tin, and silver, the aqueous bath employed is of pH 2.5 to 6.0 and contains an antimony halide and 0.5 to 5 g./l. of an addition agents elected from aromatic sulphonamides and N-substituted derivatives thereof which are free from double or condensed ring groups and contain one or two -SO 2 N< groups and one or two aromatic groups, each aromatic group containing six nuclear carbon atoms and being linked to the sulphur atom of an -SON 2  < group. Preferably the addition agent is of the form where R is phenyl, which may contain up to three substituents selected from Cl, Br, F, OH, OCH 3 , CH 3 , C 2 H 5 , COOH, NH 2 , and X, Y, X<SP>1</SP>, Y' are selected from H, CH 2 COOH, OC 2 H 5  and any two or more of which may be identical. As described, the baths are basically antimony fluoride baths which may also contain ammonium sulphate, Rochelle salt or glycolic acid. The pH may be adjusted by the addition of ammonium or potassium hydroxide or of monoethanolamine. Numerous common electroplating bath additives, e.g. saccharin, coumarin, naphthalene sulphonic acids, pyridine, thiourea, glue are stated to be unsatisfactory as well as compounds similar to those used in carrying out the invention but in which the aromatic group is naphthalene or in which the grouping of the additives of the invention is repeated, e.g. in R-SO 2 -NH-SO 2 -R-SO 2 -NH-SO 2 -R. For bright antimony deposits there may be added also to the bath copper salts, e.g. fluoride, or polymerized tetraethylene pentamine. For plating on zinc die-castings a preliminary electroplating of alkaline antimony should be applied. Specification 721,204 is referred to.

Pit head plant for discharging mine cars from a single or multi-deck mine cage, comprises a non-traversible single entry rotary tippler at each end of the cage. As shown in Fig. 1, an emptied mine car 17, on being ejected from a non-traversible tippler 13 by means of a ram 15 into a single deck mine cage 10, ejects a full mine car 16 from the cage into a second non- traversible tippler 12. The cage is then lowered and returned with a full mine car and the process is repeated in the reverse direction. In a second embodiment, Fig. 4, the first of three empty mine cars 33 in a non-traversible tippler 23 is pushed by means of a ram 27 into the first deck of a multi-deck cage 20, thereby ejecting a full mine car 32 into a second tippler 22. The cage is then moved to register the second deck with the tipplers, the second empty car 33 meanwhile having gravitated forward against a stop due to tilting of the tippler deck 251 by means of a ram 29, and the second mine car is pushed into the cage by means of the ram 27. Similarly, the third empty mine car is pushed on to the third deck of the cage, which is then lowered and returned with full mine cars and the process is repeated in the reverse direction. In a modification described in the Provisional Specification only, a pair of identical tipplers are mounted on traversing carriages running on pairs of tracks at each side of the mine shaft in which a pair of multi-deck mine cages are balanced one against the other. The outer tracks of each pair of tracks are inclined in opposite directions in vertical planes so that in the operative positions of the tipplers one tippler is inclined towards the shaft and the other is inclined away from the shaft.
