Title: Improvements in or relating to means for starting electric motors
IPC: H02K17/30
Filed: 1923-03-16
Abstract: 195,086. Suczek, R., and Sousedik, J. March 17, 1922, [Convention date]. Systems for alternating-current motors only; controllers, actuating.-An automatic starter for an alternating current motor having one or more rotor windings, comprises mutually inductive coils r, r<1> adjacent to a resistance ring o and connected through leads s, s<1> to the terminals of an auxiliary winding, which is thus subject to a high initial impedance and can only accelerate gradually. With increasing speed, the frequency of the current induced in the auxiliary winding and consequently the impedance due to the inductive coils and also the ohmic losses in the resistance ring decrease. At a sufficient speed, pivoted armatures r carrying contact-levers f are moved outwards against magnetic attraction by centrifugal force, and make connection with terminals e so as to close circuits through the main rotor winding, which in the example described, is a three-phase winding. All the parts shown in the Figures are mounted on a cast iron casing a which is carried on the motor shaft b. The casing, the shaft, and the armatures, constitute a magnetic circuit of intentionally high hysteresis, the airgaps in which can be adjusted by screws n. In a madified construction adapted for larger motors with a normal three-phase rotor winding, the centrifugal contacts are attached to longitudinally sliding solenoid cores, and the casing and its attached terminals are more substantially constructed. The invention is stated, in case of due reduction of speed, to exercise an automatic current regulating effect like an overload relay. The current connections of the starter to a motor with a three-phase main winding and a two-phase auxiliary winding are described in the Specification,

Title: Cation-active compounds derived from higher-molecular homologues of benzyl chloride or styryl chloride or from polynuclear analogues thereof
IPC: D06M13/46
Filed: 1949-03-21
Abstract: Quaternary ammonium compounds of formul  (RArCH2Bt)+Cl- and (RArCH=CHCH2Bt)+Clwhere R is alkyl of at least eight carbon atoms which may be substituted by chlorine, Ar is aryl which may be substituted, and Bt is a tertiary amine, i.e. an aliphatic amine which may contain one or several hydroxy groups, an aromatic amine, or a heterocyclic amine, are prepared by heating the amine Bt with RArCH2Cl or RArCH=CHCH2Cl.  Bt may be trimethylamine, triamylamine, triethanolamine, dimethylethanolamine, ethylbenzylaniline, 2 : 6-butidine, quinoline, acridine and many other examples.  Ar may be mono-, or polynuclear.  Aryl alkyl chlorides are prepared by the following methods.  The compounds of formula R.Ar.CH=CHCH2Cl are prepared by treatment of a hydrocarbon R.Ar.H with 1 : 3-dichloropropene in presence of a small quantity of aluminium chloride to give R.Ar.CH2.CH=CHCl, which is heated with an aliphatic alcohol R1OH and potassium hydroxide to give the ether R.Ar.CH= CH.CH2.OR1, which is heated with acid to give a styryl chloride R.Ar.CH=CH.CH2Cl.  The above ethers may alternatively be oxidized to an aldehyde R.Ar.CHO which is converted (Cannizzaro reaction) to the alcohol R.Ar.CH2OH, which is converted to the aralkyl chloride R.Ar.CH2Cl.  The last compound R.Ar.CH2Cl is also prepared by action of an aromatic compound R.Ar.H with formaldehyde and hydrogen chloride in presence of BF3 or BF3.Et2O, or by alkylation of an aromatic H.Ar.CH3 with an olefin to give R.Ar.CH3, followed by chlorination to give R.Ar.CH2Cl. Six examples are given, for example of the preparation of decylbenzyl pyridinium chloride and decylstyryl dimethyl phenyl ammonium chloride, including the preparation as above of the alkyl aryl chlorides.  The Specification as open to inspection under Sect. 91 comprises the statement that R may be substituted by halogens in general and that Bt when aromatic may be substituted by hydroxyl groups. This subject-matter does not appear in the Specification as accepted.

Title: Mixing concrete
IPC: B28C7/02
Filed: 1944-05-02
Abstract: 586,029. Mixing-machines. STANCLIFFE, C. W., and WINGET, Ltd. May 2, 1944, Nos. 8283 and 12001. [Class 86] [Also in Group XXX] In apparatus for mixing concrete the materials are fed in layers on a belt to a mixing machine driven independently of the belt driving means, and a device is provided to stop the belt when the speed of operation of the mixing machine falls below a predetermined value. The materials may be deposited on the belt from a series of hoppers and means may be provided for stopping the belt when the material in any hopper falls below a predetermined level. A hopper for supplying cement may be fed by an elevator and means may be provided for stopping the elevator when the cement in the hopper rises above a predetermined level. Hoppers 8, 9, 10 for coarse aggregate, sand and cement, respectively, are arranged above a belt 1, an auxiliary conveyer belt 11 being mounted below the hopper 10 and driven by a chain 14 from a pinion 49 on the driving shaft 15 of the belt 1. The latter is driven by an electric motor 2 through a chain 3 and pinions 4, 5. A shaft 17 driven from the concrete mixer drives through bevel gears 18, 19 a vertical shaft 20 carrying links 24 connected to governor balls 21 attached also by links 25 to a collar 22 movable on the shaft 20. The collar 22 is attached to a pivoted lever 126 which carries one of a pair of contacts 28 in the electric supply circuit of the motor 2 led from the points 50, 51. When the mixer and the shaft 17 are rotating at normal speed the governor balls 21 maintain contacts 28 together, but when the shaft 17 slows down to a predetermined speed the collar 22 falls, the circuit through the contacts 28 is broken, and the belt 1 stops. Counterweighted pivoted flaps 29, 30, 31 are mounted in the hoppers 8, 9, 10, respectively, and carry contacts 57, 56, 54 in the circuit supplying the motor 2, so that the belt 1 stops when the level of the material in any hopper falls below a predetermined value. The cement hopper 10 is fed by a chain elevator carrying buckets 34 and driven by an electric motor 36. A pivoted flap 40 within the hopper 10 carries one of a pair of contacts 41 in the circuit which supplies the motor 36 from points 37, 38. If the level of cement in the hopper 10 rises excessively the flap 40 will move downward to separate the contacts 41 and to stop the bucket elevator. The hoppers 8, 9, 10 have adjustable screeds 43, 44, 45, respectively, which determine the depths of the layers that are deposited on the belt 1. The first Provisional Specification describes a means for stopping the mixer if the water supply to the mixer falls below a certain pressure. Specifications 6424/07, [Class 86], 527,028, and 547,798, [Group IV], are referred to.
