Title: Improvements in and relating to combination locks
IPC: E05B37/12
Filed: 1967-12-05
Abstract: 1,204,200. Combination locks. FICHETBAUCHE (COFFRES-FORTS BAUCHE ET NICOLLE & CIE). 5 Dec., 1967 [27 Dec., 1966], No. 55233/67. Heading E2A. A combination lock comprises a plurality of combination rings equally spaced from a central axis, an actuating mechanism mounted for rotation about the central axis whereby the combination rings are selectively rotatable each to a predetermined angular position, a bolt movable from a locking to a withdrawn position when the combination rings are in the predetermined angular positions and bolt actuating means for withdrawing the bolt on rotation of the actuating mechanism when the combination rings are in the predetermined angular positions. The lock has seven combination rings, each ring comprising a pair of discs 52, 61 mounted to rotate in a wall 3 of the lock casing and equally spaced around an operating shaft 320 which is rotated to set the combination so that a notch in each disc 61 connected to each disc 52 by a spring catch 72 is aligned with the teeth of a slidable bolt locking plate 140 to allow withdrawal of the bolt. To set the combination, a knob 211 on the shaft 320 is pressed and moves inwardly, against the action of a spring 196, a knob 201 secured to a tube 322 coaxial with the shaft 320 to free the tube for rotation by disengaging bosses 106 on a plate secured to the wall 3 from holes in a plate 230 secured to the tube 322. The knob 201 is turned to bring a mark thereon opposite a numeral on a fixed dial 190 and to bring a gear into alignment with a disc 52. The knob 211 is then released and moves outwardly and is then turned so that the gear previously positioned by rotating knob 201 is driven by a gear 255. On the shaft 320, and engages the gear teeth of the disc 52 to set the ring. The operations are repeated until all the rings are set according to the combination. The knob 201 is then rotated to zero on the dial 190 to bring the gear into alignment with the gear of a bolt driver and the knob 211 is turned to drive the bolt driver which has a stud engaging in a slot in the latch bolt to withdraw the bolt. The bolt driver also meshes with a pinion with a shaped interior surrounding parts of catches 90, to disengage catches from the teeth of discs 52 and allow them to rotate to the initial position under the action of a spring 80. A projection on the bolt driver displaces the locking plate 140 so that the teeth thereon disengage the slots in the discs 61. To change the combination, the discs 52 are set to the combination, an external knob 291 is turned and a cam 294 thereon moves a member 170 adjacent plate 140 so that the teeth thereon engage the catches 72 joining the discs 51, 61 to disengage the discs. The discs 52 are then turned to another position. To lock the bolt a spring urged lever engages a recess in the plate 140 and abuts a projection on the bolt drive to prevent its rotation to withdraw the bolt. The lever is moved from the projection to allow withdrawal of the bolt when the knob 201 is moved to the zero position.

Abstract: 1480620 Channel balancing control SONY CORP 23 Dec 1974 [27 Dec 1973] 55579/74 Heading H4R A balance control for multichannel audio signals varies both the relative amplitudes and the relative delays of the signals in the channels. The relative delays of the signals are controlled by means of a variable delay device in at least one of the channels. As shown in Fig. 1. Left and right channel stereophonic signals are applied via preamplifiers 12 and 13 to volume controls 14 and 15 and balance control 20. From balance control 20 the two channel signals are applied to main amplifiers 16 and 17 feeding charge transfer variable delay devices 24, 25. Ganged with the balance control 20 is the control of the frequency of pulse generators 26, 27, providing shift pulses for the charge transfer devices 24, 25, arranged so that the frequencies of the pulse generators vary differentially with the position of the balance control so that a reduction in gain is accompanied by an increase in delay time and vice-versa, in each channel. The circuit for the variable frequency pulse generators, using two monostable multivibrators, is described with respect to Fig. 2 (not shown) and an application of the system to a quadraphonic arrangement providing both back to front and left to right balance is described with respect to Fig. 3 (not shown).

Title: Process for Preparing Fluorocarbon Resin Articles
IPC: C08L27/18
Filed: 1966-12-12
Abstract: 1,163,950. Fluorocarbon resin articles. GARLOCK Inc. 12 Dec., 1966 [17 Dec., 1965], No. 55593/66. Heading B5A. Fluorocarbon resin articles are prepared by removing substantially all the liquid from a homogeneous dispersion of particulate solids in a liquid, said solids comprising (a) particles of at least one unsintered fluorocarbon resin, and (b) 0-95% (based on total volume of solids) of at least one particulate filler, at least one of (a) or (b) being in fibrous form and said liquid being a volatile organic liquid which wets the fluorocarbon resin, and moulding the article at a temperature below the melt transition temperature of the resin to yield a stable unsintered resin preform. The preform may then be sintered. The organic liquid preferably has a surface tension of less than 20 dynes per cm. at 60‹ C., and fairly low volatility at ambient temperatures when the slurry is formed. The polymer is preferably polytetrafluoroethylene, polychlorotrifluoroethylene, a copolymer of tetrafluoroethylene and polyvinylidene fluoride, hexafluoropropene or a fluorinated ethylene-propylene polymer and should be in the form of small fibres. The filler may be any of a large number of chemicals and may be soluble in a solvent which does not affect the fluorocarbon resin, so that all or part of the filler can be leached out, either before or after sintering to yield a porous body. The slurry is dried by removal of most of the liquid through a liquid permeable surface, e.g. filter paper and the rest by heating. Moulding is carried out at a temperature below the melt transition temperature of the polymer at a pressure between 200 and 3000 p.s.i., and the mould may comprise a deformable caul (made for example of silicon or Viton elastomers or lead or zinc) to give improved resolution of surface features. Intricately shaped filled and unfilled fluorocarbon resin articles, e.g. clutch facings, tubing and gaskets can be made by this process, and the porous material may be used as a wick.

Title: Process and apparatus for moulding a pulp of smokable material into fibres
IPC: A24B15/12
Filed: 1973-11-30
Abstract: 1402510 Moulding smokable material pulp into fibres TAMAG BASEL AG 30 Nov 1973 [21 Dec 1972] 55652/73 Heading A2C [Also in Division B5] A process for moulding a pulp of smokable material into fibres comprises moulding the pulp by extrusion into moist fibres which break off into an upwardly flowing gas stream, drying the fibres in the gas stream, and separating the dry fibres from the moist fibres by adjusting the flow of the gas stream such that the dried fibres are discharged upwardly with the gas stream. An apparatus for carrying out this process comprises a vortex chamber 60 upwardly traversable by a gas stream, an extruder nozzle 63 located at the bottom of the vortex chamber, pointing upwards into the chamber and having a plurality of pulp outlet openings 66 connected to a pulp storage and pressure loading means for the pulp, and an outlet opening 80 for the gas stream located in an upper region of the vortex chamber and leading to a fibre separator 82 which permits fibres carried along by the outflowing gas stream to drop downwards whilst the gas stream is extracted in a different direction. The gas stream is introduced through two rings of air nozzles 78 and 79 which extend from the external atmosphere into the vortex chamber 60 and compresed air openings 67 uniformly distributed over the base plate 64 of the extrusion nozzle 63. The air outlet opening 80 is tangentially connected by a pipe 81 to the fibre separator 82 which comprises a T-shaped pipe 83 extending vertically. In use pulp is driven by pump 75 and extruded through outlets 66 in small strands and at the same time hot air is driven by the blower 72 and expelled through the outlet openings 67 so as to flow around the fibres. The fibres break off and the air induced by blower 85 enters through the nozzles 78 and 79 into the vortex chamber and flows in the form of a cyclone upwards about the axis 62. The still moist fibres are carried along by these flows and are forcibly carried upwardly and leave the vortex chamber with the air stream through the pipe 81. The fibres then fall downwardly out of the fibre separator whilst the air is extracted upwards through the blower 85. The wall of the housing 61 may be heatable and additives may be injected by means of a nozzle system 88 in the tube or into the vortex chamber 60. The specific examples disclose pulps for use in the process comprising:-1) wheat crush, wheat straw, rice chaff, oat straw, coconut shells with fibres, cocoa shells, magnesium formate, tartaric acid, potassium nitrate, diammonium hydrogen phosphate, vanillin, calcium carbonate, liquid paraffin, sodium carboxymethylcellulose, pectin, glyoxal, glycerine diethylene glycol, fruit concentrate, invert sugar and coffee bean residues; and 2) natural tobacco waste, magnesium formate, sodium carboxymethylcellulose, glycerine and glyoxal. When fibres formed from 2) are treated further glycerine from 89 may be sprayed thereon.

Abstract: 1359349 Timepieces JOHN SMITH & SONS MIDLAND CLOCK WORKS DERBY Ltd 4 Dec 1972 [4 Dec 1971] 56376/71 Heading G3T A clock is driven continuously by a weight W through an epicyclic gear system J.K.L. coupled to a Geneva mechanism G.H. actuating a switch B periodically to energize an electric motor (not shown) arranged to reverse the action of the gear system and raise the weight without interfering with the drive to the clock. The planet wheel J is carried by a barrel M and meshes with the sun-wheel K and the internal teeth on the ring L and since the sun-wheel is stationary when the motor is not running the ring L is driven by the planet wheel as the barrel revolves about the motor output shaft S and through chain sprocket (L<SP>2</SP>) drives the clock. A locking disc (N) rotating with the barrel M frees the star wheel G allowing it to be turned by stud H on barrel M and pin F turns cam D until it operates switch B to start the motor. The barrel is driven in the opposite direction until the lever B' of the switch drops into port D' of the cam stopping the motor. If switch B fails to operate, the star wheel will rotate until pin F operates a safety switch C.

Filed: 1967-12-13
Abstract: 1,244,308. Tracking radar. HUGHES AIRCRAFT CO. 13 Dec., 1967, No. 56729/67. Heading H4D. In a track-while-scan pulse radar, signals representing smoothed target position, smoothed velocity information and predicted target position information are derived by generating a variable smoothing term as a function of scan time are the time between successive scans in which signals are received from the target. Both the smoothed target position and the velocity information signals are formed by smoothing parameters which are functions of the variable smoothing term Tn. The term Tn may have three values: # n-1 , T scan  (the system time scan) or #t (time between successive scans in which signals are received from the target. The three values may be multibit numbers which are applied to the gate 49, which provide a multibit output representing #n equal to one of the three inputs. The gate 49x functions only when the system is in a normal correlation mode. The multibit gates 46, 47, 48 are controlled by the outputs of the AND gate 44 and inverters 43, 45 from the comparators 41, 42 which determine the passage of the signals # n-1 , T scan , #t through the system so as to form # n . Similar circuits are provided for automatic correlation. The flow diagram, Fig. 9, relates to the generation of #n in the manual and automatic arrangements.
