Title: Magnetic lock insert for lock mechanisms
Inventor: KASSZA TIBOR
IPC: E05B47/00
Filed: 1987-03-23
Abstract: In a cylinder lock actuatable by means of a magnetic key, the insert includes cylinder 2 rotatable by the key. Latches 8 in latch grooves formed at both sides of the cylinder are turnable together with the cylinder in the lock body. Rotors 6 rotatably journalled in rotor supports 4 have pairs of latch- receiving channels 100, 102 (Fig. 10) so that the lock may be actuated by different keys, e.g. master keys. In their wedged position, the latches prevent turning of the cylinder by means of a foreign object by engaging grooves in control rings 29a, 29b. The cylinder has conventional radial pin tumblers and a locating pin 3a provided with a catch or a steel ball for engaging and retaining the key to prevent its removal except in the locked position. <IMAGE>

Title: Spread spectrum receiver
Inventor: TWEEDIE ALISTAIR HENRY
IPC: H04B1/707
Filed: 1987-10-06
Abstract: In a direct sequence spread spectrum receiver for signals having the carrier phase modulated by an information signal and a pseudo random code sequence, the carrier signal and the pseudo random code are demodulated by a carrier phase locked loop 1-8 and a code tracking loop which overlap and share in-phase and quadrature mixers 1, 2 and filters 4, 5. The carrier phase lock loop 1-7 may be a conventional costas loop and a demodulated output is obtained from limiter 8. In the tail dither code tracking loop shown, the incoming code-carrying signal is compared with phase advanced and phase delayed versions of a locally generated code to derive a timing error for adjusting a local VCO 16 so that the received signal occurs midway between the two versions. A local code generator 15 is driven by the oscillator 16 output via a phase-shifter 17 which alternately advances and retards the oscillator phase under control of a dither generator 18. A delay locked loop in which the error signal directly controls a code generator may alternatively be used. <IMAGE>

Title: Filling containers
Inventor: FITZPATRICK NICHOLAS BERNARD
IPC: B67C3/04
Filed: 1988-04-11
Abstract: In a method of charging a flexible container such as a can or plastics bottle with non-carbonated liquid, inert gas comprising argon is dissolved in the liquid. A bowl filler to the head space of which nitrogen or argon is supplied may be used. A closure is then fitted gas-tight to the container. The concentration of dissolved gas in the liquid and the volume occupied by the head space of the charged container are so selected that on equilibration there is a super-atmospheric gas pressure in the head space of the container. The method enables thin-walled cans to be employed.

Patent GB-905874-A (GB)
Abstract: 905,874. Feeding webs. PIRELLI S.p.A. July 7, 1960 [Aug. 5, 1959], No. 23754/60. Class 100 (1). [Also in Group XXV] The tension of tape drawn from a supply roll is maintained constant as the roll decreases in diameter by braking means which acts simultaneously on the roll and on tape paid off it, the braking means consisting of a braking roller maintained in contact with the supply roll and given a torque in a direction opposite to the direction of the tape over it by an adjustable voltage motor. Paper tape drawn from a supply roll 2 is passed over a tensioning roller 7 and between a roller 11 and the supply roll 2 to bear against the roll 2 until it passes over rollers 17, 18 to be wound around a cable. The roller 7 is carried on a slide 6 urged away from the roll 2 by a spring 12, and roller 11 is fast with the rotor of a motor 10 carried in a slide 8 and urged by springs to press against the roll 2. The motor 10 tends to rotate the roller 11 in the opposite direction to the tape. Should slack occur in the tape, the motor 10 will ensure that such slack is taken up. In the event of tape breakage, the slide 6 will be drawn to strike a finger 20 that is connected to a switch 25 to stop the machine. A little before the roll 2 is completely unwound, a projection 26 on the slide 8 strikes against a push-rod 27 to actuate a switch 28 to stop the machine.

Title: Dyestuff pastilles
Inventor: WILLIAMS BRIAN JOHN
IPC: C09B67/02
Filed: 1991-01-07
Abstract: Dyestuffs (including colour-formers) are obtained in the form of solid pastilles (Fig. 1), typically of 1-3mm diameter, by solidifying droplets of the molten dyestuff while depositing them on, e.g., a moving endless conveyor belt whose inner surface is sprayed with cold water. Preferably the molten droplets are extruded from two coaxial apertured cylindrical vessels, the outer of which rotates about the inner. The process is particularly applicable to colour-formers e.g. of the phthalide, fluoran or carbazolylmethane series, the pastilles of which dissolve rapidly in organic solvents thereby facilitating the mfr. of heat. and pressure-sensitive papers. <IMAGE>

Title: Method of guiding a strip of material
Inventor: NARISHIMA SHIGEKI
IPC: B21C47/34
Filed: 1991-09-12
Abstract: The method comprises feeding the strips between a pair of guide members 15, through pinch rolls 13 and on to a winder 12. When the strip passes the upstream end of the guide members, the members are moved inwardly to a predetermined size greater than the strip width. When the leading end of the strip enters the pinch rolls 13, in a second stage the members move further together. The second stage may be governed in response to the output from sensors 17, 18 which detect the strip width and the position of its centre. The positions of the guide members 15 may be continuously varied to accommodate the varying strip width. By varying the position of the centre line of the strip with respect to a mandrel around which the strip is wound, a coil may be produced having a uniformly wound portion affording a flat surface, which portion protrudes on one side of the coil. <IMAGE>
