Title: Bit ring counter with bit marker
IPC: H03K5/15
Filed: 1967-01-16
Abstract: 1,116,421. Electronic counters. GENERAL PRECISION SYSTEMS Inc. 16 Jan., 1967 [16 May, 1966], No. 2220/67. Heading G4A. In the quiescent condition one stage of a ring counter is in a low current stand-by condition and all other stages are off; the application of an input pulse triggers said one stage briefly to high-current condition before it turns off and brings the next stage to stand-by condition. A clear pulse, Fig. 5, applied to terminal 11 sets the first stage 10 comprising an NPN and a PNP transistor 42, 40 to a low-current condition. A shift pulse applied at 18 is amplified at 66 and passed through transformer 60 as waveform 77 to all stages. The negative pulse is amplified by stage 10 to produce an output at 16, after which the positive spike turns off 40 followed by 42. The R-C circuit 45A, 56 then turns the next stage 20 to stand-by condition. An NPN transistor may be placed between stages with the base fed from an extra secondary of transformer 60 (Fig. 4, not shown).

Title: A device for calibrating pressure sensitive instruments
IPC: G01L27/00
Filed: 1962-01-22
Abstract: 935,728. Pressure responsive apparatus. INTERCONTINENTAL DYNAMICS CORPORATION. Jan. 22, 1962 [Jan. 23, 1961], No. 2259/62. Class 106 (2). A testing instrument for calibrating the altimeter and air-speed indicator of aircraft comprises two manifolds, 22 and 26, which can be connected, by lines 27 and 28, to the static and Pitot inlet ports, respectively, of the aircraft, the static manifold 22 being maintained at a pressure, with respect to vacuum, pre-set on an "altitude" dial 15 and the Pitot manifold 26 being maintained at another pressure, with respect to the static pressure, pre-set on an " air-speed " dial 16. The pressures are maintained constant at the chosen values with the aid of transducers 60, 45 and electronic servoamplifiers 62, 46 which supply to solenoidoperated control valves 61, 44 regulating the manifold pressures output current proportional to error signals generated by the difference between the pre-set pressures and the existing pressures as measured, in terms of altitude and air-speed respectively, by a calibrated altimeter 13 and air-speed indicator 14. The altimeter 13 is a standard diaphragm or capsule type in which the static pressure is compared with vacuum. This pressure may be chosen above or below the ambient pressure by manual operation of valve 50 whereby manifold 22 may be connected to the high-pressure side or the low-pressure side of pump 30. The correct sign for the static error signal is automatically given by a reversing switch 59 adjusted by movement of the valve 50. The pump 31 for the Pitot manifold 26 has its inlet connected to the static manifold 22. Should the servos fail, the manifolds may be bled manually by means of valves 70 and 41. The control valves 61 and 44 have resilient portions which come down on to obliquelytruncated conical nozzles: in this way the rate of air flow can be finely controlled.

Title: Improvements in or relating to methods of bonding
IPC: A43D25/18
Filed: 1962-01-23
Abstract: 999,821. Laminates and laminating; seaming non-metallic sheet material. BRITISH UNITED SHOE MACHINERY CO. Jan. 23, 1962 [Jan. 31, 1961 (2); May 4, 1961], No. 2341/62. Headings B5K and B5N. [Also in Divisions A3 and B2] A method of bonding comprises the steps of directing a stream of heated gas against a surface to be bonded, introducing a heat responsive adhesive composition in powder form into the stream so that it is heated to a tacky condition and is carried on to the surface where it forms a layer of discrete particles adherent to the surface, heating the particulate layer by the stream of gas to fuse the particles to form a substantially continuous layer and pressing a second surface against the continuous layer. A hand-held gun is used comprising a barrel 12 containing electrical heating means 106, a pipe 18, the opening 84 of which is adjacent the barrel orifice 13, a container 16 for powdered adhesive and a device 60 for supplying adhesive to the pipe. In operation, air passes through the barrel, is heated by the heating means therein and emerges as a stream of heated air from the orifice 13; air passes through the pipe and issues as a stream from orifice 84 and on actuation of a trigger 20 the device 60 operates whereby adhesive is supplied to the pipe and issues therefrom as a stream of particles which is directed into the stream of heated gas issuing from the barrel. The adhesive may be a mixture of two different heat fusible resins, one of high melting point and the other preferably thermo-setting, of low-melting point. The resins may be in the form of separate particles or the low-melting resin may be coated on to the high-melting resin. High melting point resins specified are linear polyesters or copolyesters of terephthalic and isophthalic acids with glycols, heat-fusible polyamides, polystyrene and vinyl polymer resins. Low melting point resins include thermosetting e.g. phenol aldehyde, melamine aldehyde and epoxy resins, and thermoplastic e.g. the gasoline-insoluble residue from the distillation of pine tar (Vinsol resins), and low molecular weight polystyrenes. The adhesive may include a colouring material, either in powder form or applied as a dispersion or solution in a volatile liquid, which becomes visible on heating whereby it is clear to which parts of the surface to be bonded the adhesive has been applied. Suitable colouring materials are pigments, e.g. carbon black, chromium oxide, iron oxide, cadmium red and flake aluminium pigment or dyes such as " Resoform Brown B.R. Pure " and " Natural Oil Brown," or a highly coloured resinous material such as a resorcinol-formaldehyde resin. The method and apparatus may be used to bond shoe uppers to insoles in a conventional lasting press. Specification 962,851 is referred to.

Abstract: 1,156,893. Protective systems. VARIAN ASSOCIATES. 16 Jan., 1968 [16 Jan., 1967; 24 Nov., 1967], No. 2382/68. Heading H2K. [Also in Divisions H3 and G3] A microwave oscillator (see Division H3) comprises an amplifier, e.g. klystron 2 with a feedback path feeding power amplified by the amplifier to the input, to sustain oscillation and including an attenuator 5b, e.g. a PIN diode. An arc protector is incorporated for sensing an arc in the output waveguide, comprising a photo-cell 10 disposed in the waveguide, any output from which is fed via an amplifier to control attenuator 5b so as to reduce the power level of the oscillator until the arc is extinguished. Alternatively (Fig. 6, not shown), the photo-cell output is fed via an amplifier to the gate of a S.C.R. connected in series between a power supply and the variable attenuator, so as to cause the former to deliver a voltage to the attenuator reducing the attenuator loop gain below unity, stopping oscillation. When the arc is extinguished the S.C.R. is returned to its "off" state by opening a switch in the power supply lead, thereby removing the drive to the attenuator and allowing normal operation to be resumed.

Title: An improved method and means for the determination of relative velocities and relative accelerations occurring in very minute relative movements of two members
IPC: G01P3/50
Filed: 1920-01-26
Abstract: 162,371. Darwin, Sir H., and Cambridge & Paul Instrument Co., Ltd. Jan. 26, 1920. Time-distance recorders; accelerometers. - A method of and means for determining the relative velocities and accelerations occurring in short periods of time consists in measuring the rate of change of a small unit of length, e.g. one-hundredth of an inch. According to the invention, six electric contacts are made successively by the linear movement imparted to a tappet under the influence of the phenomena, and the movement is recorded by means of a galvanometer such as described in Specification 20654/13, [Class 37, Electricity, Measuring &c.], in conjunction with any known manner of recording time intervals. The operating. tappet a is screwed into a boss j integral with the base of a clamp e in which is securely held six metal laminµ contacts b separated from one another by sheets of insulating material d. The laminµ b project beyond the clamp limbs and are bevelled on either side to form a pointed ridge in a plane containing the tappet axis and at right angles to the planes of the laminae and so formed that it projects farther from one side of the clamp than the other, as shown in Fig. 5. The other contact l is formed of plastic material, such as lead, and is mounted in a recess in a sleeve k arranged parallel with the tappet axis. The sleeve is internally threaded and is adapted to be moved longitudinally by the operation of a hand-wheel n and screw m. A spring r constantly urges the sleeve k towards the screw m and is maintained' in set position by a locating screw p engaging one of a series of notches in the shoulder s. By displacing the axis of the sleeve k, fresh surfaces of the lead may be presented to the laminµ. By varying the thickness of insulating material between the laminµ, the function of the rate of contact may be varied in proportion to the rate of tappet movement. In a modification, six stretched wires disposed at equal intervals apart may be substituted for the plastic contact member and a single movable contact member takes the place of the laminµ.
