Title: Improvements relating to electric motor controlling systems
IPC: B23Q15/00
Filed: 1946-04-03
Abstract: 610,381. Control of A.C. motors. WADKIN, Ltd., and SIMS, W. L. April 3, 1946, No. 10330. [Class 38 (iii)] The control of a three-phase A.C. commutator motor for a machine tool is effected by selecting tappings in the stator windings by means of multiple switches which are situated remotely from one another, a first switch, in one position thereof, being effective to control the motor independently of a second switch which is rendered operative to control the motor in another position of the first switch. In one position of a switch 1 a supply-line R is connected to a point D in a stator phase-winding 23 of a three-phase commutator motor 4, the line S being connected to a point H in a stator winding 22, and points A, E and K being joined together to provide low-speed motor operation. In another position of the switch 1, a switch 2 may be moved to one of its operative positions to provide the same connection for low-speed operation. In another position of the switch 2 the line R is connected to the point D and the line S to the point H, the left-hand contacts of a switch 3 being connected together to form a star-point to which selected stator-winding sections are connected by movement of the switch 3 thereby to control the motor speed. In a reverse setting of the switch 2, the switch 3 is rendered inoperative and the connections of the stator windings to the supply-lines are the reverse of those obtaining in the previous low-speed settings. A similar arrangement is described in the Provisional Specification, comprising a first three. positional switch with eight pairs of contacts, a second four-positional switch with ten pairs of contacts, and a three-pole multi-way selector switch.
Patent GB-358420-A (GB)
Title: Improvements in colouring matters and intermediates of the benzanthrone series
IPC: C09B3/06
Filed: 1930-04-01
Abstract: The substances obtainable by condensing together benzanthrone or a derivative thereof and formaldehyde in a sulphuric acid medium, are interacted with an organic acid halide or anhydride in presence of an acid condensing agent (for example, aluminium chloride), with or without oxidizing agents such as gaseous oxygen.  The starting materials, which may be dibenzanthronylmethanes or related substances, are converted into new intermediates or dyestuffs which may be applied as pigments, or from the vat, or as direct dyes for cellulose ether or ester materials.  The nature of the product is influenced by the proportion of reactants and conditions of the reaction.  Thus if p  a benzanthrone-formaldehyde condensation product is subjected to prolonged treatment with sodium-aluminium chloride and benzoyl chloride there results, after oxidation, an alkali-soluble body, whereas a shorter heat treatment results in an alkali-insoluble product.  In some cases the products may be treated with oxidizing agents such as sodium hypochlorite, which treatment may, if desired, be followed by alkylation.  In examples (1) a benzanthrone-formaldehyde condensation product is reacted with sodium-aluminium chloride and benzoyl chloride in presence of oxygen and the product treated with bleach liquor; it dyes cotton from the vat, and wool from an acid suspension, in yellow shades; after methylation by means of dimethylsulphate the product is rendered alkali-insoluble but dyes the same shades on cotton from the vat; (2) acetyl chloride is substituted for benzoyl chloride in example 1 and gives a similar product; (3) benzene sulphonyl chloride is substituted for benzoyl chloride in example (1); the product is insoluble in alkali and alkaline hydrosulphite.

Title: Electronic timepiece
IPC: G04G5/02
Filed: 1973-11-19
Abstract: 1449596 Electronic timepieces CITIZEN WATCH CO Ltd 19 Nov 1973 10445/76 Divided out of 1449193 Heading G3T An electronic timepiece with an electro-optical digital display 627, and an electronic circuit 608 for setting the time indication to the correct time in response to control signals received via a discriminator circuit 602 and resulting from manual operation of a setting switch 601, as described in Parent Specification 1449193, is provided with a safety feature to prevent erroneous alteration of the time indication due to accidental operation of the switch in that the discriminator circuit determines whether a signal from the switch 601 is a proper correction control signal or a spurious accidental signal. When the discriminator senses a proper correction control signal from the switch it produces an "unlock" signal in a line 604 which sets a counter timer 610 to zero and resets a flip-flop 606 via an AND gate 611. This results in an "unlock" or data enable signal in a line 607, delivery of correction signals in line 628 to the correction circuit 608 and an output from an AND gate 612 to start the counter 610 counting. The counter 610 counts clockpulses from a frequency divider 623 and when a predetermined count has been reached, e.g. corresponding to a correcting operation of one minute duration, the counter produces an output to a gate 605 resulting in a "lock" signal being applied by the flip-flop 606 via the line 607 to "lock" the correction circuit 608 and prevent operation thereof. A separate lock switch may be provided, which can lock the correction circuit without waiting one minute.

The air passes through the inner portions of the impeller 14 and then, after deflection through almost 180 degrees, laterally into the guiding channel 21 of the fan 20. The comparatively heavy particles of blasting medium cannot undergo this deflection and continue on into the impeller 14. The spent medium passes through holes in the conveyer belt 2 into a chamber 40 and thence through a flap 42 biased by counterweight 41 falls in a fire screen into a tank 50. A fan (not shown) draws air through a slot 52 and an opening 53. The air passes through the screen of medium, removing dust and broken medium into separator 55 and leaves through opening 54 which may be provided with filters. An inlet passage 60 for air is automatically opened when a door 61 is opened. A sight-glass 51 is kept clear by the air entering through slot 52. The suction tube 31 is provided with a humidifying device operated as a result of siphon action caused by the air stream.

IPC: F41A9/26
Filed: 1918-07-02
Abstract: 123,261. Foulds, H. M. July 2, 1918. Machine guns.-Consists in arranging the cartridges in spiral formation on a disk magazine by which they are successively brought into line with and inserted into the barrel, held therein during firing, and finally extracted. The invention may be applied to guns having either a fixed or movable barrel. The cartridges 2 are spirally arranged on a disk capable of ready attachment to a plate 4 which, together with a similar plate 23 is mounted to rotate under the action of a clock spring 21a in bearings 7 which move radially in a frame 9 to feed the cartridges one by one into line with the gun barrel. The radial feed is obtained by the engagement of the ends of a hollow pin 10 in spiral grooves 5, 24 in the plates 4, 23 respectively. The frame 9 can move on rods 33, 34 against the action of springs 41 towards or away from the barrel to allow of insertion and extraction of the cartridges. The firing pin 11 is cocked against a vertically sliding sear 17 during the inserting movement and after insertion, a cam 20 on the frame 9 engages a pin 21 on the sear 17 to release the firing pin. Corresponding to each cartridge is a rearwardly extending pin 25 having a cut away part 32 which co-acts with a pawl 26 to permit rotation of the magazine only in its rearward position, the extent of rotation being governed by a pawl 27 pivoted at 28 to the pawl 26.
