Patent GB-2202266-A (GB)
Title: Locking fastener
Inventor: COLLINS PAUL DAVID
IPC: E05B13/10
Filed: 1987-03-17
Abstract: The locking fastener for a door or window has a handle 10 pivotally mounted on a base plate 18 and a barrel lock 20 mounted for rotation in a bore 72 in handle 10. The lock 20 has a locking position in which an eccentric formation 22 prevents pivotal movement of handle 10 and an unlocking position in which pivotal movement is not prevented, the lock 20 having a manually operable knob 54 in a first axial position of which the lock 20 is held in its unlocking or locking position, and in a second axial position of which it is free to move between locking and unlocking position. Figure 5 illustrates lugs 64,66 on knob 54 which are moved out of slots 78 in barrel 52 to allow lock rotation. As shown, handle 10 has catchport 16 engageable with a catchpiece on window frame but fastener may be used with espagnolette fastening. Eccentric formation 22 is shown as pin 22 to engage protrusion 50 from base plate 18 to prevent pivotal handle movement - protrusion 50 also abuts a wall 82 of a housing portion 13 of handle 10 to prevent an intruder turning handle contrary to normal direction. Axis of lock is shown parallel to pivot axis of handle but it may be perpendicular. Knob/lock may be of plastics material. <IMAGE>

Title: Reduced bandwidth video transmission
Inventor: PEARSON DONALD EDWIN
IPC: H04N19/593
Filed: 1987-04-01
Abstract: The bandwidth reduction of a video signal is attained by processing with a two-component model, the first being a very economical but recognizable cartoon or line drawing which is derived from the grey-level image by valley detection 210. The second component is generated by using the cartoon as a sampling template to sample the grey-level image, so that samples, for example two, of the original image are taken at the cartoon lines. A (or several) further sample is taken mid-way between the valleys and the original image is reconstructed using two dimensional second order (quadratic) interpolation between the sampled points. To generate the most suitable line drawing the grey level image is thresholded, the discontinuous lines generated by valley detection are filled in, i.e. made continuous and this image is subjected to boundary extraction, 230 which produces a continuous line drawing with lines of one pel width. Streaks produced in the final, interpolated image may be removed by allowing distinction between valleys and edges and then applying conditional adaptive filtering to the interpolated image. <IMAGE>

Title: Printing apparatus
Inventor: PICHOT JEAN MARIE
IPC: B41J13/10
Filed: 1987-09-22
Abstract: A printing apparatus 10 employs flexible fingers 60 (which display elasticity and flexibility in the direction wherein a printhead 54 moves across the surface of a presented document but show great rigidity at an angle of 90 degrees to the surface of a document) to keep a document in contact with the platen at the print station. The fingers 60 allow the printhead to move along its printing path 102 by pushing them aside, the fingers being automatically restored to their undeflected position by their own elasticity. A chamfered section 88 guides the leading edge of the document flat onto the printing bed 12. The fingers 60 are preferably formed from a continuous transparent polymer sheet folded with fold lines at 90 degrees to the document surface and held in slots on a support member 58. <IMAGE>

Title: Security nut
Inventor: BACK CLEMENT JOHN
IPC: F16B31/02
Filed: 1987-09-29
Abstract: A security nut 1 comprises an internally-threaded circular fastening portion 2 for tightening against a workpiece and a non-threaded driving portion 3 engageable by a spanner.

Title: Rocker joint pin type CVT chain
Inventor: SUGIMOTO YOSHIAKI
IPC: F16G5/18
Filed: 1990-04-23
Abstract: A rocker joint pin type CVT chain has link plates 1 connected by rocker joints, each including a rocker pin 2 and a seat pin 3 in an insertion bore 7 of the link plate 1, the rocker pin 2 and the seat pin 3 making rolling contact along opposing rolling arcuate surfaces thereof as the chain bends and straightens when passing around a pulley. At respective minimums, the sectional area 8 of the link plate formed between the link plate insertion bore and the outer periphery of the link plate relative to the pulley, is greater than the sectional area 9 formed between the link plate insertion bore and the inner periphery. The radii of curvature r of the inner rolling contact surfaces of the rocker pin and seat pin are smaller than those R of the outer rolling contact surfaces. The fatigue strength at the minimum sectional area portions is thereby increased and the deviation from the chain center line of the contact point of the opposing rolling contact surfaces is minimized in a straightened position of the chain, thereby reducing the load applied to the inner minimum sectional area portion. …<IMAGE>…

Title: Pepper grinder.
Inventor: CHEN TZUNG-WEN
IPC: A47J42/46
Filed: 1991-06-03
Abstract: A grinder for pepper is operated by pressing or releasing a manipulating plate 2 which is pivotably, Fig 5, or non-pivotably (Fig 11) movably mounted in an opening of an outer wall of a cylindrical body 1 in such a way that a grinding wheel 52 is rotated by a gearing mechanism 3, 34, 41, 4, 51. The gearing mechanism is operated by pressing the manipulating plate 2 inwardly and is stopped by releasing the manipulating plate 2 which is urged to its original position. Thus the pepper corns falling into a gap between a grinding wheel 52 and a grinding cylinder 53 can be ground. The gap between the grinding cylinder 53 and the grinding wheel 52 can be adjusted to change the degree of coarseness of the ground pepper. <IMAGE>

Title: Retractable antenna
Inventor: HARRISON PETER DEX
IPC: H01Q1/24
Filed: 1991-07-13
Abstract: An antenna assembly comprises an elongate radiating antenna (11) movable between a retracted position and an extended position. A pair of concentric conductors (9, 10) provide coaxial feed means to the antenna (11). In the retracted position the antenna (11) in conjunction with the coaxial feed means (9, 10) constitute a quarter wavelength transmission line which is short-circuited by a conductive flange (15) on the antenna. A short-circuited quarter wavelength transmission line electrically appears as an open circuit at the feed point. The antenna is thus automatically decoupled when it is moved to the retracted position without the need for additional switching or screening means. <IMAGE>

Title: "lpc speech encoding"
Inventor: AHLBERG JONAS TOMASSON
IPC: G10L19/06
Filed: 1992-01-09
Abstract: A method of quantizing the line spectral frequencies (LSF) when calculating the parameters of an analysis filter included in a LPC-speech coder. The line spectral frequencies form an alternative to the filter parameters with unambiguous correspondence. It is earlier known to construct sum polynomials (P) and difference polynomials (Q) from the direct form coefficients of filters and thereafter to calculate the roots of the polynomials which correspond to the line spectral frequencies. This calculation is carried out by means of iteration. According to the inventive method, the roots of the sum and difference polynominals are not calculated, and the polynominals are instead investigated with the aid of pro-selected test frequencies (ftp1' ftqf1' ftp2' ftq2'...) which are speech typical. The polarity of the two polynominals (P, Q) is investigated for each of these test frequencies. When a polarity change occurs between two test frequencies, there is chosen one of these frequencies, for instance the higher frequency, which gives a given root (p1 and q1 respectively) of the sum polynominal (P) for the difference polynominal (Q), and therewith a line spectral frequency (LSF1 and LSF2 respectively). This method obviates the need for complicated calculations and improves the use of the properties of the polynominals. <IMAGE>
