Title: Screw-thread cutting mechanism
IPC: B23G1/22
Filed: 1955-11-09
Abstract: 786,688. Screwing die-heads. LANDIS MACHINE CO. Nov. 9, 1955 [Dec. 31, 1954], No. 32011/55. Class 83 (3). A screw-cutting die-head has a number of chaser-holders 72, Fig. 1, movable substantially radially in a body 30, Fig. 6, by cams 106, each having a cylindrical body 108 slidable in a cylinder 110 and fixed by a screw 214 to a ring 216 surrounding a latch-member 184, 186 on the body. Differential feed-means cause the holders to move during threading to produce a taper-thread. The work W frictionally engages a member 142 adjustably mounted on a screwed member 120 mounted in bearings 116, 118 in a pilot 112 slidable axially and centrally of the body. Two cylindrical members 156, Fig. 7, are mounted side-by-side in a bore 154 transversely of the axis of the pilot, and have holes slidably receiving levers 158, each pivoted at its upper end 166, Fig. 13, to a part 168 secured to body 30 and having a groove 164 mounting a block 174 engaging a pivot 176 of a part 178. This part carries a block 198 having a helical-groove 200 engaged by a helical-cam 204, Fig. 10, on a ring 202, turnable on the latch-member to move. the parts 178 radially simultaneously, 'and vary the taper produced by the head. The latch-member is adjusted axially by stop-screws in the flange 32 of body 30 to maintain the angular relationship between the levers and the body. Thus, as the work, together with the pilot, is fed relatively to the body, the latch-member slides relatively to the body and carries with it ring 216, thus moving the holders radially to cut a taper thread. The latch-member is secured to a ring 236, screwed on to ring 216, by latches 252, Fig. 16, each having a notch 258 engaging an abutment-ring 248 secured to ring 236. The latches each carry a lever 276 pivoted thereto and engaging with one arm, a hole in the wall of a fixed cylinder 260, in which the latch is slidable, the other arm 288 protruding into the path of the pilot and carrying an adjusting- screw 286. Thus, after a predetermined length of thread has been cut, the pilot pivots the levers to retract the latches into the cylinders, thereby releasing rings 216, 236 which are moved by springs 232 to remove the chasers 76 from the work. When ring 248 is latched to member 184, 186, rotation of ring 236 provides initial radial-adjustment of the chasers, and the rings are then locked by key 240 bolted to ring 216 and engaging a dog 238 in ring 236. Backlash may be taken up in either direction by biasing-springs 334, loading member 184, 186 in one direction or the other relatively to the body 80. A flange 46 is secured to the rear of the body, which flange is secured to a machinetool-spindle 44. Lubricant may be supplied to outlets adjacent each chaser from a bore 294 in spindle 44 via bores and channels 298, 302, 304, 310, 318, 322. The chasers are individually set radially, each by an adjusting-screw 90 locked by screw 94, with relation to one which has the screw &c. replaced by a block 96 to render it non-adjustable.

Title: Improvements in the production of ornamental effects on fabrics consisting of or containing a linear aromatic polyester
IPC: D06Q1/02
Filed: 1953-11-19
Abstract: Ornamental effects are produced on a textile fabric consisting of or containing linear aromatic polyester yarns by applying to localized areas thereof an organic swelling agent for the polyester and bringing about shrinkage in such localized areas by means of heat. In an alternative process, fabrics composed of linear aromatic polyester yarns and other yarns are treated in localized areas or all over with an organic swelling agent for the polyester which does not substantially swell the other yarns and shrinkage of the treated polyester is effected by means of heat. The organic swelling agent, which may be applied by printing as a paste employing starch, gum or other thickener, may be phenol, cresol, resorcinol, pyrogallol, alpha- or beta-naphthol, ethylene glycol mono-phenyl ether, phenol glycide ether or orthodichlorbenzene.  The mixed fabric may contain yarns of cotton or viscose rayon and may be pattern-woven so that the polyester threads are brought to the surface.  The fabric may be heated in a tensionless condition by hot air or by radiant heat, e.g. when the fabric is being carried on a brattice or conveyer, or by passing through a heated liquid inert to the material treated.  In examples: (1) a polyester fabric is printed in stripes with a paste containing gum and phenol, passed tensionless through a drying machine at 120 DEG C., washed and dried tension-free; (2) a fabric consisting of viscose rayon and polyester threads woven so that the polyester threads provide a surface pattern is padded in an emulsion containing phenol and gum tragacanth and further treated as in (1). Specification 761,075 [Group VIII] is referred to.

Title: Improvements in or relating to electrical systems for transmitting angular movements
Filed: 1936-11-24
Abstract: 485,930. Electric control systems. CONTRAVES AKT.-GtES. Nov. 24, 1936, No. 32202. Convention date, Aug. 5. [Class 40 (i)] In a system for transmitting angular movements, a delay device is introduced between the transmitter and receiver to produce a fixed or variable time delay in the transmission time. As shown in the Figure, the contacts of a commutator type transmitter are connected to magnetic recording devices 8 associated with endless steel bands 9 and adapted to produce impulse records of the movements of the contact 1, which are conveyed by the bands to pick-up devices 11 connected to relays 16 adapted to control the resultant field type receiver 25. The time taken between recording and picking up the impulses constitutes the time delay in the transmission. Solenoids 27 are provided for eradicating the magnetic records. The record bands may be replaced by a single band. In a modification, the commutator switch controls three carrier currents of different frequencies, the modulations being recorded on a single band. Instead of employing a magnetic record, a perforated record may be used. Moreover the time delay may be introduced by interposing in each transmission circuit any one of the following arrangements : (1) an electrical delay network ; (2) an acoustical device comprising a loud-speaker and a microphone mounted at each end of a sound conduit ; (3) a heat-insulating band carrying thermochromic material which changes colour under the action of heat rays and after cooling reassumes its original colour ; in this case, the transmitter controls lamps which affect the thermochromic material and produce temporary records which subsequently control photo-electric cells connected to the receiver ; (4) instead of using thermochromic material, luminescent substance, which is affected by visible or ultra-violet light and glows after a time period, may be employed. Specification 481,820, [Group XXI], is referred to.

Filed: 1971-07-09
Abstract: 1400415 Internal shoe drum brakes; slack adjusters GIRLING Ltd 7 July 1972 [9 July 1971 11 Sept 1971] 32301/71 and 42462/71 Heading F2E  Means for automatically adjusting the separatoin between two relatively-movable members, e.g. a strut 6 and a brake shoe 2 of an internal shoe drum brake, comprises a lever 19, 20, Figs. 5, 8, mounted on one of the members, e.g. shoe 2, a cam 13 rotatably mounted on the lever and adapted to bear on the second member, e.g. strut 6 to define the spacing between the members, a ratchet element 14 associated with the cam, and a pawl 23 co-operating with the ratchet element for rotating the cam 13 relative to the lever 19 when pivotal movement of the lever in one direction exceeds a predetermined amount. The strut 6 indirectly bears on the opposite shoe 1, Fig. 8, so the latter shoe may be regarded as the above-mentioned second member, and it is the separation between the shoes which is automatically adjusted, to take up lining wear. Lever 19 is connected to shoe 1 by a tension spring (not shown); the ratchet element 14 is in the form of a disc integral with cam 13, and a second cam 12 is provided, both cams being keyed on a spindle 11. The spindle 11 engages in a notch 10 provided in the web of shoe 2. Pawl 23 having locating notches 25, 26 is retained in an opening 24 in the web of shoe 2 by a spring 18 which also urges it into contact with the ratchet disc 14, Fig. 6. The shoes are applied by a double-ended hydraulic cylinder (not shown) located between their upper ends and released by a tension spring (not shown). In operation, when the shoes are separated on brake application, lever 19 is pivoted clockwise about end 20 by the spring (above referred to) which connects it to shoe 1, so spindle 11 is moved slightly out of notch 10, and ratchet disc 14 is drawn away from pawl 23. If lining wear results in pawl 23 jumping a tooth, disc 14 is rotated clockwise on brake release, so a portion of each of cams 12, 13 of greater radius now contacts the end of strut 6. Preferably strut 6 forms part of a mechanical applying means for parking as shown in Fig. 8: such application does not result in slackadjustment. In Figs. 1 to 4 (not shown) the pawl is of a different shape, and is accommodated in an edge notch of the web; spring 18 is located above the web.

Title: Improvements in or relating to acetylene generators
IPC: C10H15/12
Filed: 1936-11-27
Abstract: <PICT:0486016/IV/1> A device for indicating the quantity of calcium carbide in the revolving screens of acetylene generators comprises one or more members which rest on the carbide in the revolving screen, and which are adapted to move as the quantity of carbide in the screen changes, and a pointer movable with the said members and visible from the exterior of the generator.  The pointer may be arranged to control the charging of the carbide, e.g. by closing the starting circuit of an electric motor driving the charging device when the content of the drum has reached a predetermined low limit, thus replenishing the supply of carbide in the drum.  In a specific embodiment, a shaft 6, fitted with fingers or "floats" 7 resting on the carbide 8, projects into the drum 4.  The floats 7 move as the quantity of carbide changes, thus rotating a pointer 9, attached to the shaft 6, and moving over a scale 10, which thus registers the quantity of carbide in the drum, and also, if desired, controls an electric circuit as stated.

Abstract: 1,034,259. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 16, 1963], No. 32644/64. Heading G4A. A memory plane comprises first and second capacitative memory matrices having corresponding conductor overlap points, an arrangement of capacitative couplings associated with overlap points of one matrix being the complement of the corresponding arrangement of the other matrix, there being means to pass a drive signal to sense-circuit-means via any one of a number of drive signal paths through the first matrix, each drive signal path having the same total shunt impedance provided by capacitative couplings of both matrices. This arrangement enables all the stray capacitances to be tunedout using only one inductor for the whole memory plane. Each matrix mentioned is a printed circuit card with capacitor plates on each side linked by row conductors on one side and column conductors on the other. Selected pairs of capacitor plates are punched out in the first matrix to store data, and those plate pairs in the second matrix corresponding to left-in pairs of the first matrix are also punched out. A bit is read from the memory plane by applying an A.C. drive signal to its row conductor (in the first matrix) and earthing the other row conductors of the first matrix. The column conductors of the first matrix are connected to respective diode read-out gates, one of which is enabled by a gating pulse to pass the desired bit to the base of an amplifying output transistor. The base of this transistor is earthed through an inductor present to tune-out stray capacitances. Each column conductor of the second matrix is connected to the corresponding column conductor of the first matrix at the input to its respective read-out gate. All the row conductors of the second matrix are permanently earthed. In a modification mentioned. parallel read-out of a whole row may be accomplished.
