Abstract: 1499825 Winding armature cones POSSIS CORP 17 March 1975 [19 March 1974] 12132/74 Heading B3A A method of winding a coil into slots 104 of an armature core 103 comprises holding the armature in a wire receiving position, shielding a first portion of the core and exposing at least one pair of slots, and winding a first coil in the exposed slots by rotating an annular member or ring 114, 116 about its axis which lies generally normal to the longitudinal axis of the core, the ring having means for receiving the wire from a supply and discharging it adjacent the core. The core is mounted vertically in a releasable holder 167, Fig. 9, on a tube 168 which is rotatable in small increments by an indexing motor 172. The core is located between the members 114, 116 and the commutator is shielded, except for a selected hook, to prevent previously attached leads from leaving their hooks. Wires 136, 151 are fed from spools through tubular guides 138, 153 mounted coaxially with the annular members and needles 134, 149 into the core slots 104. The members 114, 116 are rotated in opposite directions by a toothed belt 129 which engages teeth 128, 144 on the peripheries of the members and the belt is passed around a pair of superimposed pulleys (151), (161), Figs. 7, 8 not shown), the pulley (161) being driven. The wires 136, 151 are guided into the slots 104 by cone-shaped surfaces 178, 178A of shrouds 173, 174, which are formed with recesses for holding the core 103. The wires are guided at the uppermost end face of the core by pivoted tabs 192, 192A, Fig. 9 and (191), (191A), Fig. 10 (not shown), the tabs being swung clear of the core by actuators 202, 202A, to allow the core to be inserted into and removed from the apparatus. When a pair of coils have been wound, the drive to the pulley (161) is stopped, the core is indexed by the motor 172 and winding is recommenced after loop leads of wire have been connected to the appropriate commutator segments. Cutters 171 are provided on the holder 167 to sever the wire after winding. In an alternative construction of winding apparatus, Fig. 4 (not shown), the annular members are provided with bevel gear teeth (23) on their peripheries and they are in mesh with a bevel gear (24) which rotates them in opposite directions. In a further construction only one belt driven annular member is provided. To release the armature core, the shroud halves, where two annular members are provided, are separated by cam operated pivotal fingers (41), Fig. 4, or they may be pivoted open by actuators (224), (232), Fig. 15 (not shown).

Title: Lubricating grease composition
Filed: 1956-04-20
Abstract: A lubricating grease useful under highly corrosive conditions comprises a lubricating oil gelled with a metal soap of a fatty acid or hydroxy fatty acid and minor proportions of an oil-soluble alkaline earth metal salt of a hydrocarbon sulphonic acid and a mono-ester of an aliphatic carboxylic acid and a polyoxyalkylene glycol wherein each oxyalkylene radical contains 2 to 6 carbon atoms. The lubricating oil may be a mineral oil or a synthetic lubricant such as the aliphatic esters of dicarboxylic acids, liquid polyoxyalkylene glycols and oxides, liquid phosphorus esters and silicate.  Soaps mentioned are the alkali or alkaline earth metal soaps of fatty or hydroxy fatty acids, calcium or lithium stearate or 12-hydroxy stearate being preferred.  The hydrocarbon sulphonates are preferably petroleum sulphonates and may be neutral or, preferably, basic.  Examples are believed to have the formula (RSO3)M.OH, where M is an alkaline earth metal and R is a hydrocarbon radical such as naphthenyl, alkyl naphthenyl, aryl or naphthenyl aryl.  The molecular weight of the sulphonates should be between 400 and 750.  The polyalkylene glycol mono-esters have the general formula H-(O-R)n-OOC-R1 where R is an alkylene radical containing 2-6 carbon atoms, n is a whole integer, preferably between 5 and 20, and R1 is an organic radical, preferably an alkyl radical having between 8 and 24 carbon atoms.  Examples of suitable glycols are polyethylene, polypropylene, polybutylene, polyamylene and polyhexylene glycols and combinations thereof. The acids used to form the esters comprise both saturated and unsaturated aliphatic monocarboxylic acids including both fatty acids and hydroxy fatty acids.  Examples are capric, lauric, myristic, palmitic, stearic, and oleic acids.  Optional ingredients are the oil-soluble polyvalent metal salts of dithiocarbamic acids (many examples listed) and amine type antioxidants such as phenyl-alpha naphthylamine and guanidine derivatives.  In examples, calcium sulphonates and polyethylene glycol mono-oleate were added to a mineral oil gelled with lithium 12-hydroxy stearate.  Zinc dibutyldithiocarbamate was also added in one case.

Title: Improvements in or relating to electrical apparatus for indicating the flow of an electric current in a telephone line
Inventor: JONES ARTHUR FREDERICK
IPC: H04M19/02
Filed: 1959-04-10
Abstract: 881,274. Telephone systems. GENERAL ELECTRIC CO. Ltd. March 24, 1960 [April 10, 1959], No. 12203/59. Class 40 (4). An electric lamp 4, Fig. 1, connected in the collector circuit of a transistor 5 is lit when current flows in the line wire 1 of a telephone line. The lamp may be used to give a visual indication of a telephone call, or of a " busy " condition where two telephone instruments share the same line. A battery 6 supplies the collector current to operate lamp 4. In the absence of current flow in wire 1 the base 10 and emitter electrode 7 are at the same voltage, and the collector path is of high impedance so that insufficient current is supplied by battery 6 to light lamp 4. If current flows in the direction of arrow 3 an emitter/base voltage is developed across resistance 9 and collector current lights lamp 4. The apparatus may be made independent of the direction of flow of line current by inserting a full wave rectifier in series with the line wire 1 and the base/ emitter circuit of the transistor (Fig. 2, not shown). In another arrangement (Fig. 3, not shown), a single lamp responds to each direction of current flow by using two transistors 5 and resistors 9, one for each direction of current flow. Each embodiment responds to flow of alternating current operating a telephone bell, the visual indication being useful when a subscriber has a number of telephone instruments on his desk.

Filed: 1940-07-31
Abstract: 542,935. Button-attaching machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). July 31, 1940, No. 12390. [Class 112] The free end of the sewing thread is held below the work so that it is enclosed within the stitches of a group securing a button. With a four-hole button, two such groups are used, the thread being cut between the groups. A thread-cutting and end-holding blade 80 slides between a throat plate X and a blade 90 pressed resiliently against the blade 80. A transverse cutting and holding edge 94 on the blade 80 co-operates with a similar edge 90x on the blade 90 and a short longitudinal cutting edge is provided at 96x. The normal stitches of a group are made through the aperture 95 and at the last stitch the blade 80 is moved so that the rotary looper will drag the thread over the edge 96x to sever it. Prior to the commencement of a group, the blade 80 is moved so that the first descent of the needle is in the space 93 and, on the ascent of the needle, the blade 80 is moved back so that the free thread is cut and gripped by the edges 94, 90x. The thread is so held until the last stitch and then the blade 80 is moved to make the edge 96x effective again. In addition to the usual steady tension, intermittent tension and needlebar take-up there are a thread clamp, which is closed during the first stitch of a group, a thread controller, similar to a take-up, which is actuated to draw up some of the thread prior to its being cut and gripped at the first stitch and to pay out the thread for the following stitch, and a device which opens the two normal tensions during the period when the loop-taker is spreading the first thread loop of the cycle. These various devices are operated by cams on a vertical shaft which makes one revolution for two groups of stitches and a cam on this shaft trips the stop gear when the two groups are completed.
