In a blind rivet assembly, in which a bolt, Fig. 1, is rotated, e.g. by means of flats 11, to be drawn into a nut, Fig. 2, and thus drive a riveting collar, Fig. 3, over a tapered end 26 of the nut to expand the collar on the blind side of members (36, 37) to be joined, Fig. 4a (not shown), the bolt head 15 is undercut at 16 to receive the coned end 31 of the collar 30 Further, the collar diameter is reduced at 34 between its ends to regulate its expansion and its internal diameter 32 at one end is a fit on the unthreaded part 14 of the bolt shank but otherwise is larger to embrace, before expansion, the tip of the tapered end 26 of the nut 20. The taper of the nut end 26 is graded so that the tip is less acutely tapered. For locking, a portion of the nut thread 22 is non-circular in section. Its unthreaded counterbore 23 fits the part 14 of the bolt shank and it has recesses 25 in its head 24 to aid prevention of its rotation during rotation of the bolt. The bolt head 15 may have a recess or surface to aid release of the fastener whose loading is determined by a breakneck 17 in the bolt thread 13.

Title: Processing circuit for television chromatic signals
IPC: H04N9/44
Filed: 1974-12-04
Abstract: 1492567 Colour television INDESIT INDUSTRIA ELETTRODOMESTICA ITALIANA SpA 4 Dec 1974 [7 Dec 1973] 52396/74 Heading H4F The phase of operation of a switching voltage generator 23 controlling a PAL switch 24 and a further switch 14 is determined by the output of a phase comparator 16 having one input connected to the output of a subcarrier regenerator 18 and a second input connected to switch 14 and a 90 degree phase shifter 12. The apparatus may receive a PAL signal having either "swinging" bursts or a burst (of phase 135 degrees relative to the B-Y modulation axis) only in every second line period. The bursts are separated by a burst gate 10 and the subcarrier regenerator 18 receives, via switch 14, the output of phase shifter 12 during every second line period and generates a subcarrier in phase with the thus received bursts. For a received signal having "swinging" bursts the bursts passed to subcarrier regenerator 18 when the phase of switching voltage generator 23 is "correct" are of phase 225 degrees relative to the B-Y modulation axis, the burst input to phase comparator 16 from switch 14 in alternate line periods and phase shifter 12 in the intervening line periods is of phase 225 degrees in every line period, and phase comparator 16 provides, via a low-pass filter, a positive output which prevents a gate 21 passing a signal and leaves the operation of switching voltage generator 23 undisturbed. If, however, the phase of switching voltage generator 23 is "wrong", the subcarrier regenerator 18 receives bursts of phase 315 degrees and the burst input to phase comparator 16 alternates in phase between 135 and 315 degrees and the phase comparator provides, via the lowpass filter, a zero output to enable gate 21 to pass a pulse from a generator 22 to switching voltage generator 23 to reset it. For a received signal having a burst only in every second line period no bursts are passed to subcarrier regenerator 18 if the phase of the switching voltage generator is "wrong" and again the output of phase comparator 16 is zero. The output of subcarrier regenerator 18 is passed via 45 degree phase shifter 20 and 90 degree phase shifter 26 to B-Y demodulator 6, and also via a detector 19 to control a colour killer circuit 4 and an amplifier 2. In an alternative embodiment the output of phase comparator 16 controls switching voltage generator 23 directly.

Title: Apparatus for Reading Coded Information
Inventor: TRIDGELL RONALD HUGH
IPC: G06K7/016
Filed: 1965-12-10
Abstract: 1,164,450. Sensing arrangements. H.M. POSTMASTER GENERAL. 12 Dec., 1966 [10 Dec., 1965], No. 52666/65. Heading G4M. Timing signals are obtained from at least one timing bit PDT aligned with or interspersed with coded data bits PD e.g. phosphorescent marks on postal mail to be sorted. In one embodiment, detector PSI responds to radiation passing through an aperture R1, and a detector PST responds to radiation passing through any of apertures R2-R14. Initially, a shift register T1-T14 is reset over RSL, and a marker bit is entered in the first stage T1 When PDT passes R1, the output from PSI is blocked at PCG1, but when PDT passes R2 at the same time as the first code bit PD is passing R1, the timing pulse produced by PST and differentiator DIF opens gates PCG1, PCG2 and applies a shift pulse to the shift register so that the first data bit enters stage T1. Subsequent data bits are entered in the shift register as the timing bit PDT passes apertures R3-R14, until the marker bit reaches T14. The amount of radiation falling on PST increases as successive bits are read, and to achieve maximum sensitivity without overloading PST, resistors TR are switched in to successively reduce the sensitivity as binary " 1 " bits are entered in the shift register. In a modified arrangement, each position C2-C14 has a code group arranged perpendicular to the direction of travel A, R1 is replaced by a set of apertures and PSI by a set of detectors feeding individual shift registers, each set corresponding in number to the number of bits in each code group, and detector PST responds to groups containing two binary 1's. In either of these arrangements, PST can be replaced by a separate detector for each aperture R2-R14, the detector outputs being commoned. A further embodiment, Fig. 4 (not shown), utilizes alternate timing and data bits recorded on the mail, these being sensed by PSI and PST through single, individual apertures R1, R2. In this case a timing pulse is generated by a divide by two circuit which is triggered each time PST detects a timing bit or a binary " 1 " data bit or subsequently to the sensing of a binary " 0 " bit by PSI, whereby only the data bits are entered in the shift register.

Filed: 1975-12-23
Abstract: 1524850 Accessing data stores FERRANTI Ltd 21 Dec 1976 [23 Dec 1975] 52679/75 Heading G4A Consecutive bits forming part(s) of a multiple word operand and addressed simultaneously in a store S, selected ones of the addressed bits are enabled for read-out, and a shift network OM1, OM2 arranges the read out bits in the desired sequence. Read out of entire operands with left or right shift by specified amounts is also possible. A ROM provides a mask pattern which varies from all 1's when no shift is required to a single 1 and 15 0's when a 15-bit shift is required, the pattern being reversed for opposite shift directions. For each bit of a word location an address multiplexer AM selects the upper or lower address input in dependence on the corresponding mask bit applied thereto, the address inputs being supplied by adders AD1, AD2 which pass an input address N unchanged or incremented to (N+ 1). In this way blocks of bits in adjacent word locations in store S may be addressed. Further multiplexers EM pass the mask pattern or an all 1's pattern to enable read-out of selected ones of the addressed bits from the store S. Shift network OM1, OM2 is controlled to shift the bits end around into the required order, e.g. to read bits 8-23 of a 2 x 16-bit operand, bits 8-15 from address N and bits 0-7 from address (N + 1) (bits 16-23 of the operand) require to be endaround shifted left by 8 bits. A gate G1 forces extension of the sign bit for right shifts in network OM1, OM2.

Abstract: 1,209,921. Builder motion. JAMES MACKIE & SONS Ltd. 25 Jan., 1968 [6 Dec., 1966], No. 54589/66. Heading D1D. A multi-head winding machine for plastic tape drawn from a controlled speed source, e.g. an extruder having at each head a winding guide such as a flyer and driven around a non-rotary support, e.g. a sleeve (20) see Fig. 2 not shown on which a package is built has builder mechanism for relatively reciprocating the winding (guide and package support and superimposing on the reciprocation a unidirectional motion, the mechanism for producing the reciprocation being common to all the winding heads and the drive for the unidirectional motion being independently disconnectable at each head. As shown the rails 16 which carry the non-rotary package supports are attached to a plate 23 reciprocated by a cam and lever arrangement 26, 27. A bracket 41 attached to the package support carries a rack 40 engageable with a pinion 44 on a shaft 48 mounted on the rail 16. Shaft 48 is rotated by an indexing mechanism 50 through a fixed angle on each reciprocation of rail 16; thus the unidirectional component of the builder motion is produced. Rack 40 is held in contact with pinion 44 by a spring loaded plunger 45 and can be moved out of contact by a member 51. Thus each head can be arranged to be at a different stage in its wind and the heads can be doffed and donned one at a time so reducing wastage of the continuously delivered tape. After donning the rack 40 is lifted relative to pinion 44 to begin a new wind.
