Title: Improved manufacture of stockings, gloves, hosiery-goods and similar articles of cotton, half-silk, half-wool and the like
IPC: A41D31/00
Filed: 1919-01-28
Abstract: Stockings, gloves, hosiery goods and similar articles of cotton, half silk, half wool, &c. have their greater portions dyed by an oxidation black process, but the parts subjected to most wear are dyed black or approximately black by some other process. The following are examples of the manner of carrying out the invention as applied to stockings: (1) The portions to be stronger are made of a yarn dyed a black-blue, a black-green or a black obtained by some other process, such as by a sulphur black, developed black, aniline black dyed in the bath, wet oxidized aniline black, &c.  (2) The stocking may be made of grey material, the parts subjected to most wear being printed with a protective or reducing substance, such as salts of metals forming alums, or their hydroxides (for example, chrome alum made basic with caustic soda and glycerine), or ferrous or stannous salts or organic products, such as dextrin; the whole stocking is then dyed by the oxidation black process.  (3) The portions subjected to the least wear are made of materials in the grey, while for the foot &c. yarns are used on which are deposited metallic oxides or other protective or reducing bodies, and the whole dyed by the oxidation-black process.  (4) In (3) the yarns may be treated before or after impregnation with a suitable dyestuff in a dark grey, or that dyestuff may be added to the protective solution. (5) Two kinds of yarn may be used, threads in grey and threads prepared by one of the above methods.  (6) The portions subjected to most wear may be treated by a mercerizing process, the mercerized yarns being subsequently treated as above.

Title: Electrical connector assemblies
IPC: H01R24/12
Filed: 1976-01-20
Abstract: 1489723 Electrical connectors AMP Inc 20 Jan 1976 [7 Feb 1975] 02110/76 Heading H2E An electric connector assembly comprises a socket and a plug 12 having two parts which are joined together but may be relatively rotated. The socket has a cavity at one end to receive a portion of the plug 12, each plug part having an external lug which during mating of the plug and socket move along a groove in the cavity, latching of the housings being effected by rotating one plug part relative to the other so that one of the external lugs travels along a slot that communicates with the groove in the cavity. In one embodiment, shown, terminals 42 on a retaining plate 48 are received in passages 16 in shell parts 18, 20 of the insulating socket housing. A detent 32 is situated in each of two slots 28 in communication with a respective pair of different sized grooves 24, 26. The plug comprises part 68 and a cover 66. Part 68 includes through apertures 104 for receiving contact sockets 98, each terminating a wire 92 of a power cable 90, and members 118 which are received in cover 66 and have serrations 128 which bite into the cable sheath to provide strain relief. Part 68 and cover 66 move together until projections 116 on part 68 engage in a respective slot 82. Lugs 78, 110 are then aligned with a corresponding groove 24, 26 until fully inserted. Rotation of the cover 66 then causes lugs 78 to ride over a respective detent 32 and move along a slot 28 to latch the plug and socket. In a modification of the socket (Fig. 8, not shown), the outer profile thereof is received in a profiled cavity (134) formed in an electrically powered hand drill. In a further modification (Figs. 9 and 10, not shown) the socket (152) has a keying projection (168) and locking lances (170). A panel (172) has a profiled aperture (174) including a keying recess (176). The socket may then be mounted on the panel (172) and a resilient sealing member (178) provides a tight environmental seal between the plug and the socket.

Title: Improvements in or relating to buckles for securing the ends of sanitary napkins to a sanitary belt
IPC: A61F13/64
Filed: 1954-01-25
Abstract: 754,221. Buckles. KIMBERLY-CLARK CORPORATION. Jan. 25, 1954 [Feb. 12, 1953], No. 2147/54. Class 43. A buckle for securing the end of a sanitary napkin to a belt is of flat form of resilient flexible material, preferably of plastic material such as nylon moulded in one piece, having a predetermined thickness to provide the required strength in the area in which the napkin tab is gripped and having in another area above the gripping area and adapted for suspension of the buckle from the belt, a reduced thickness and greater flexibility for conforming to body curvature. The buckle contains at least one flexible tab retaining member projecting from one side towards the opposite side in overlying relationship to a tooth projecting upwardly from the bottom bar of the buckle. As shown, the buckle has a pair of arcuate resilient retaining strips 15 projecting from opposite side arms 7, 8 to provide a restricted passage over the centre of a tooth 11 projecting from the lower bar 9, the strips 15 being of smaller width and/or thickness than the outer frame 7, 8, 9, 10 to render them more pliable than the frame which tapers in thickness from its upper to its lower end so that the tooth 11 cannot readily be twisted out of the plane of the buckle and the upper part of the buckle conforms easily to body curvature. Alternatively, a major upper portion of the buckle is of uniform thickness increasing from a point about two-thirds down to the end of the buckle. Humps 13 projecting from the sides 7, 8 provide recesses 14 for receiving edge portions of tabs suspending the buckle from the belt. The angularity of the sides of tooth 11 and the lower edge portions of the strips 15 results in gradually widening pockets 12 to receive most of the tab material impaled on the tooth 11 which alone may be made thicker and/or wider than the bottom bar 9 of the frame. The buckle may be moulded in a two-part die provided with rounded corners for all edges of the buckle with the gate for injecting the material located in the wall of the cavity portion for the upper frame bar 10 so that the sprue 22 remaining after the moulding operation may be cut off close to the bar, the slight roughness remaining being received within the suspending key.

Title: Improvements in or relating to television and like apparatus
IPC: H04N3/12
Filed: 1930-01-21
Abstract: 347,254. Television receivers. BAIRD, J. L. and TELEVISION, Ltd., 133, Long Acre, London. Jan. 21, 1930, Nos. 2155, 5129, and 17253. [Class 40 (iii).] Relates to television receivers employing a screen of lamps or shutters actuated by a switching device and has for its object to prolong the time of operation of the lamps &c. In the arrangement of Fig. 1, each lamp &c. 10 is connected to a contact 12 of a switch and impedances 21, each also connected to a contact 12, are connected to a source 20 of biasing current. An impedance 9, which may be variable, may control the amount of bias. In the arrangement of Fig. 2 the lamps &c. 10 are supplied with part of their full operating current during a time less than the exploring cycle. One brush 30, Fig. 2, of the commutator supplies the picture current to the lamps and a second brush 27, which may comprise two portions as shown, supplies the lamps with a steady current which is insufficient to cause an illumination but will prolong an existing illumination. The brush 27 may contact with several contacts 12. When shutters are employed, Fig. 4, condensers 52 or inductive circuits may be connected in circuit with the shutters 10 and a separate brush 53 may short circuit each condenser or inductive circuit after a predetermined time interval, while a brush 49 may charge each condenser prior to the actuation of its corresponding shutter. The shutters 130, Fig. 6, may close under the action of a spring 135, or the like, or may be closed by a separate electromagnet actuated at a predetermined time interval after the opening electromagnet 133 has been actuated. This closing may be effected by a separate brush on the switching device. An impedance 15, Fig. 1, or resistance 8 may be connected between the rotating arm of the switch and the source of current to prevent a surge of current injuring the lamps &c. This antisurge device also supplies an alternative path for the current should a lamp fail. Part of the constant current fed to the lamps may be supplied through a preferably variable resistance connected in parallel with the modulator. A high resistance between the return lead of the lamps and the shunted modulator supplying an alternative path for the current should one lamp fail, Fig. 3, not shown. According to the Provisional Specification one or two ground glass screens may be placed in front of the lamps &c., and lamps may replace the shutters of Fig. 4. Specifications 222,604, 291,121, 320,639, 336,655, [all in Class 40 (iii), Telegraphs, Electric ], and 347, 741 are referred to.

Title: Improvements in and relating to tools for supplying heat to workpieces to produce soldered joints
IPC: B23K3/047
Filed: 1965-01-19
Abstract: 1,085,972. Soldering. P. J. GILL. Jan. 6, 1966 [Jan. 19, 1965], No. 2230/65. Heading B3R. A tool for applying heat to workplaces to produce a soldered joint comprises two pivotally connected lever arms each carrying a thermally conductive bit, spring means engaging the arms to bias the bits together and electrical heating means for heating the bits. Each lever arm 11, Fig. 1, is of hollow rectangular cross-section formed of channel section members 12 and midway along the length of each arm a recess 18 is provided which does not extend across the entire width of the arm and has an arcuate bottom surface, a bearing piece 21 in the form of a short annular member being engaged in the opposed recesses of the arms. A handle 14 of insulating material is provided in the end 27 of each of the arms through which extends the electrical supply lead 16 which supplies an electrical heating element 26 in the other end 28 of the arm. Extending from the end 28 of each arm is a solid or laminated replaceable copper or copper alloy bit 29 having an arcuate recess 32, the bit being in contact with the heating element. On the outer side 39 of each arm at the end 28 is engaged the free end of a U- shaped spring 41, the base 42 of the spring passing through clearance apertures 43 in each arm below the bearing piece 21. The spring holds the assembly of arms and bearing piece and urges the bits together. Solder is provided in the grooved end of a socket and when the socket is received between the bits and heated thereby the solder will flow. The tool may be used with a tool rest which includes a thermally responsive switch in a holder engaged by the bits so that the temperature of the bits may be automatically regulated. Alternatively the rest may have a controller responsive to the weight of the tool so that when the tool is supported by the rest the rate of supply of electrical energy is reduced. A flat faced bit may be employed to solder flat plates of metal.

Title: Face milling head with bar-shaped milling tools
IPC: B23F21/22
Filed: 1978-01-19
Abstract: Each rod-shaped milling cutter (3) projecting beyond the front end face (4) of the basic body (1) of the milling head has a plane flank clearance face (5) and a plane head clearance face (6). These two faces, together with the plane rake face (7), form the cutting edges (8, 9). The flank clearance face (5) and the head clearance face (6) of each milling cutter (3) are allocated to one another in such a way that their intersection line (10) forms a plane (12) with the longitudinal axis (11) of the milling-cutter shank. This plane (12) is parallel to the milling-cutter shank surface (13) bearing against the base of the milling-cutter locating groove (2) and in the assembled state is parallel to the milling-head axis (14). The re-grinding of these two clearance faces and of the rake face (7) can thus be carried out without adhering to the proportionality between the amounts of stock removal at the clearance faces (5, 6) and the amount of stock removal at the rake face. <IMAGE>

Title: Electrical relays
IPC: G04F3/06
Filed: 1977-01-20
Abstract: In this electronic multi-range time-delay relay, the setting member, e.g. potentiometer, which serves to set the time in a stepless fashion is operated by means of a transparent rotary knob (1) which overlaps the major part of the relay front panel (4). The time scale (12), which preferably occupies the edge region of the rotary knob (1), can be provided on the rotary knob or on the front panel. A correspondingly smaller changeover knob (2) is present on the rotary knob (1) for the purpose of preselecting the timing ranges. The changeover knob (2) is mounted on a spindle which is guided through the rotary knob (1) and the setting member for setting the time in a stepless fashion. The spindle is part of a changeover switch by means of which different resistors, for example, for the individual timing ranges are switched into the circuit. By comparison with the conventional juxtaposition of stepless and range time setting, this superimposed arrangement of knobs and setting means facilitates optimum use of space for miniaturisation in conjunction with a simultaneously guaranteed accuracy of setting. <IMAGE>

Title: Improvements in or relating to the manufacture of maltose
IPC: C13K7/00
Filed: 1943-02-11
Abstract: Maltose is prepared by the hydrolysis of liquefied starch paste with air-dried malt at a temperature of about 125-130 DEG  F. and a pH of about 5 for a period of about 48 hours or longer.  The malt is dried in a current of air at a temperature not exceeding 85-90 DEG  F. and should not exceed 10-15 per cent by weight of the starch.  A little toluene may be added to inhibit any fermentation or development of bacteria.  The starch paste may be made by running a cream of starch with 2 per cent air-dried malt into boiling water.  The reaction products are filtered to remove the malt grains, boiled with decolourising charcoal, filtered again and evaporated in a vacuum pan to a syrup containing about 80 per cent solids.  The syrup by seeding with a little crystalline maltose can be set as a solid magma of crystalline maltose.  Reference has been directed by the Comptroller to Specification 226,812, [Class 127].

Abstract: 989,569. Automatic control. TOKYO KEIKI SEIZOSHO KABUSHIKI KAISHA. Jan. 21, 1963 [Jan.20, 1962], No. 2508/63. Heading G3R. A servomotor is controlled by electrical switching means to which are applied an electric control signal and an electric feedback signal dependent on operation of the servomotor, the feedback being applied through an element which produces a phase lay at low operating frequencies and no lag, or even a lead, at frequencies at which the system would be unstable. As applied to an automatic pilot for maintaing a ship on a fixed heading, a repeater compass 7, operated from a gyro compass 6, adjusts a potentiometer 10 so that a relay unit 2 is energized to operate a reversible servomotor 3 in the sense necessary to correct course deviations by adjustment of the steering (not shown) through reduction gearing 11. A follow-up potentiometer 12, operated by the servomotor, supplies feedback signals through an adjustable resistance-capacity network R 1 R 2 C which is designed to stabilize the system by introducing a differential component of control and also has a delay which decreases with increase of frequency. Other forms of resistance-capacity feedback circuit having similar characteristics for introducing differential or differential plus integral components are described, and non-linear resistances such as semi-conductor diodes may be included in the parallel branch of the network to increase the differential component at high signal levels.
