Title: An improved method and apparatus for making flexible conduits
IPC: B29C48/15
Filed: 1962-10-16
Abstract: 956,340. Conduit for control cables; Bowden mechanisms; flexible shafts. TELEFLEX Inc. Oct. 16, 1962 [Dec. 4, 1961], No. 39091/62. Headings F2K, F2P and F2U. [Also in Divisions B3 and B4] A method of forming a flexible conduit includes punching equally spaced holes along the length of a continuously moving flexible strip 18, offsetting the solid portions between the holes alternately towards either face of the strip to form projecting bridge portions 12 and extruding a casing 17 of a synthetic plastics material about the strip. The finished conduit carries a slidable or rotatable wire 16 and forms a control cable. The strip is preferably metal, but may be of plastic. In the apparatus claimed, the strip 18 is drawn from a reel 20 by a device 24 (see Divisions B3 and B4), which punches circular holes in it and offsets the bridges 12. The strip is then hardened in a device 26 where an R.F. generator and coil heat the strip before it is quenched in an oil bath (Fig. 8, not shown), and tempered by passing through a second coil-generator heating device at 170. The plastic cover is extruded on to the strip by the machine 32 and the plastic coating is water-cooled in troughs 34. 36 is a tensioning device with caterpillar belts 176 and 178 which keeps the strip taut throughout the aforementioned processes. Reference has been directed by the Comptroller to Specification 705,792.

Title: Laser output measuring instruments
IPC: G01J1/42
Filed: 1975-09-05
Abstract: 1496515 Measurement of laser output GENERAL ELECTRIC CO Ltd 5 Sept 1975 [12 Sept 1974] 39833/74 Heading G1A [Also in Division H1] An instrument for measuring the energy or power of a laser comprises a photo-detector associated with an optical system for diffusing the light from the laser, a circuit for integrating and amplifying the photo-detector output and visual display means, the photo-detector being provided with heating means to maintain its temperature constant during operation. As shown in Figs. 1 and 2, the detector is a double photodiode whose face exposed to the radiation comprises an inner first anode and an outer concentric second anode, the common cathode being located on the opposite face of the detector crystal. A D.C. voltage of 100-140 is applied to the cathode. The oven 4 for the detector is electrically heated, to maintain 70‹C. The optical system comprises opal glass scatter screens 5, 6, 7, 8 and a perforated metal plate 9, a final opal plate 11 forming a closure for the oven 4. The detector has a fast output from its second anode 24 to terminal 26, whereby to provide a direct display of the detector input variations on a digital voltmeter, an oscilloscope (e.g. for indicating laser pulse length or shape) or an analog meter. The first anode (25) signal is used to supply the integrator circuit C 1 , R 2 . When laser pulses are being analyzed, each pulse charges up capacitor C 1  and after the pulse has ended the voltage stored thereby, adjusted in accordance with the photo-detector dark current, is amplified by operational amplifier A 1 . The amplifier output is used to trigger analog-todigital converter 28, via switch S, capacitor C 3  and amplifier A 2 , so that the converter is triggered to receive the laser output representative signal only at the end of each pulse. The converter is provided with a numerical four-digital electroluminescent visual display 12 and an output to a voltmeter at 35 via digital-to-analog converter 34 and amplifier A 3 . In the other position of switch S, the instrument can be zeroed. Alternative arrangements. The instrument may be modified to deal with high pulse repetition rates or continuous beams. The detector may be a silicon photodiode which is particularly sensitive in the range 0À8-0À9Á, for use with a neodymium doped laser. Alternative detectors are of germanium mercury cadmium telluride or lead sulphide. A pyroelectric device may be used. The optical system may incorporate beam-splitter; diffusing/reflecting devices and absorption vanes. The apparatus may be all in one housing or divided into two housings as indicated in Fig. 1 by the dashed line.

Abstract: 1393939 Hydraulic shock absorbers A A COWAN 31 Aug 1972 [13 Sept 1971] 40299/72 Heading F2S In a shock absorber where the flow through the piston on rebound is partly along the same path as the flow on jounce, there are two passageways 46, 48 in the piston, both of which are open (as shown) when the piston is at rest and on jounce movements, and there is a pressure-responsive valve member 44 which may close the passageway 48 during rebound movements. The valve member 44 is biased away from a circle of apertures, which form the passageway 48, drilled through a hexagonal extension 38 of the piston. The passageway 46 is permanently open. A pin 30 (adjustable by means of a ball and detent, or a cam screw, Fig. 11, not shown) further restricts the flow through the piston. The exterior of the cylinder is formed with fins 62 (depicted in more detail in Fig. 1, not shown) which aid in cooling the shock absorber liquid, and provide alternative abutments for the lower seat 64 of a coil spring 20.

Abstract: 1521076 Vehicle sliding roof mechanisms KAROSSERIEWERKE WEINSBERG GmbH 7 Oct 1975 [7 Oct 1974] 41022/75 Heading B7B In a sliding roof assembly a cable 12 is used for transmitting movement to a roof cover 5 from an open position displaced rearwardly of the roof opening to an intermediate position aligned beneath the roof opening and into a fully closed position in which the cover occupies the roof opening. As shown the cover 5 is moved from a position under a fixed part of the roof to the intermediate position by means of a cable 12 passing along a duet 17 and connected with a slide 19 which moves in a guide rail 13. The slide 19 has a finger 15 which moves in a section 21 of a guide link attached to the rear edge of a roof cover 5. When cover 5 reaches the intermediate position the finger 15 enters a second section 22 of the guide link which is in line with the path of movement of the finger, thus ceasing to transmit any longitudinal force on the cover. This final movement of the cable is used for actuating a lifting device for raising the cover into the fully closed position. As the cover 5 reaches the intermediate position levers 27 pivoted thereto engage pins 28 mounted on the ends of thrust bars 26 which pivot the levers as a result of their transverse movement applied by a crank disc 25 rotated from the cable 12 via an eccentric pin 30 on the disc 25.

[Also in Division B8] An assembly including a container for introducing a washing agent which is in solid form, e.g. tablets or powder, or in liquid form, into washing liquid, in a dishwashing machine comprises a bimetallic strip connected with a retaining device arranged on the container or on a means for closing this container, that when the washing liquid reaches a predetermined temperature this strip releases this device or means and thereby permits the container to be emptied into the interior of the dishwashing machine. A container 1 Fig. 1., is fixed to a carrier 3, connected to a bimetallic strip 4 having an opening 6 engaging a projection 7 of the cover 2 of the container. When the temperature in the machine reaches a predertermined value the bimetallic strip 4 moves outwardly, as indicated by the broken lines in Fig. 1, and out of engagement with projection 7, so that the cover 2 is released and the contents of the container 1 are discharged into the machine. In an alternative embodiment a container 9 Fig. 2 is pivotally mounted at 11 on a carrier 10. A bimetallic strip 12 is fixed to the carrier 10 and at its top and engages behind a stop 14 on the container 9. When the machine temperature rises to a predetermined value the strip 12 moves out of engagement with stop 14 and so allows the container 9 to swing downwardly and discharge its contents into the machine.

A read-only magnetic data store comprises as shown, an array of ferrite rods 12 arranged in rows and columns, a plurality of planes 10 of drive lines 11, the rods extending through the planes and projecting at each end, and each drive line in a plane being associated with a respective row and being magnetically coupled to a selected combination of rods in that row, and a sense line 13 for each column magnetically coupled to all rods in the column, the sense line comprising two similar sense windings arranged one at each side of the planes of drive lines and coupled together in aiding relationship. The drive lines 11 may be formed on printed circuit boards, either a portion 15 or 16 around each hole 12A, B, C &c. being severed by any suitable means so as to selectively form the desired magnetic couplings with the rods to be passed through said holes.
