Title: Device for driving pins into masonry, structural members or the like
IPC: B25C1/14
Filed: 1965-08-27
Abstract: 1,061,349. Cartridge-actuated tools. CARL BAUER. Aug. 27, 1965 [Sept. 7, 1964], No. 36964/65. Heading B4C. A cartridge-actuated tool for driving pins 29 into masonry comprises a driving piston 34, 35 and a cartridge holder 38, 40 normally situated outside the range of action of a release mechanism but brought into range for firing when a pin, inserted into a holder 21, is pressed against a workpiece, the firing position for the release mechanism being the same irrespective of the length of the pin. The pin holder 21 is mounted in a cover 10 which is retained on a tubular member 11 for relative sliding movement by means of a circlip 12. The cartridge holder is formed with a sleeve portion 38 in which the drive piston 34 moves, the piston being formed with a sloping surface 50 for co-operation with a similar surface on an enlarged end 22 on the pin holder 21. In operation, a pin is inserted into the front end of the holder and retained there by magnets 28 acting on a disc 30 placed over the end of the pin. Upon pressing the point of the pin against the workpiece, the disc acts against the holder 21 which, in turn, presses on the sleeve 38 thereby moving the cartridge holder into the cocked position. When the cartridge is fired the piston is driven forwardly to drive in the pin. In the event of the pin being driven into soft material the sloping surface SO of the piston strikes the end 22 of the holder 21 to absorb the excess energy. In a modification, the end 22 of the holder is provided with slits so that it may be expanded into contact with the cover 10 by means of a tapered section formed on the piston.

Title: Process and apparatus for measuring compressive forces set up in moulding sands and other fire-proof construction materials under moulding conditions
IPC: G01N25/16
Filed: 1962-10-02
Abstract: 1,017,107. Testing moulding sands. W. PATTERSON and D. BOENISCH. Oct. 2,1962 [Oct. 2,1961], No. 37271/62. Heading G1S. The compressive forces set up in moulding sands and other refractory materials under moulding conditions are tested by packing the sand into the form of a thin curved plate and heating the concave side. The force required to prevent change in shape of the plate or the deformation due to heat when opposed by a known load are measured e.g. by a dial gauge or optical means. From the results the compressive strength of the sand may be determined. In a preferred embodiment the test plate 16 is held by a ram 14 and ring 13 used to form the plate, and formed of a material of high thermal conductivity, the apparatus being located in a water bath. The plate 16 is heated by a burner 58 and movement due to expansion of the plate is transmitted by a rod 34 to a plate 41. Air is supplied to chambers 43, 44 between the plate 41 and a plate 42. The pressure developed increases as the plate 41 moves towards the plate 42 and reduces the escape gap between the plates. Thus the pressure, on a gauge 50, indicates the expansion of the test plate 16. In another embodiment the ring 13 and ram 14 are of a material of low thermal expansion and are mounted on quartz rods.

Title: Improvements in power transmission couplings
Inventor: BLAU ROBERT EDWARD
IPC: F16D35/00
Filed: 1962-10-02
Abstract: 945,458. Hydraulic couplings. LINK-BELT CO. Oct. 2, 1962, No. 37331/62. Heading F2C. An hydraulic coupling comprises a driving housing 10 having ribs 26 providing cylindrical surfaces 28 and a rotor 51 having ribs 57 providing cylindrical surfaces 59 and which is driven by the viscous drag of liquid between the surfaces 28, 59. The rotor 51 is helically splined on a part 39 of a driven shaft 38, and is biased by springs 62 to a central position in which the surfaces 59 are axially aligned with the surfaces 28. Each spring 62 is compressed between the rotor 51 and a spring retainer 63 carried by the rotor. Each spring retainer 63 has a flange 64 which in the central position of the rotor abuts a thrust-plate 48 secured to the part 39. Each retainer 63 is mounted on the rotor by a plurality of studs 67 which are secured to the rotor and slidably fit through openings in a flange 66 of the retainer and are provided with enlarged heads 68 which limit the outward movement of the spring retainer. The length of the studs is such that when the rotor 51 is in its central position each spring retainer simultaneously engages the heads 68 of its studs and the thrust-plate 48 with little or no pressure being exerted between the thrust-plate and the retainers. On the transmission of torque the rotor 51 tends to screw along the part 39 of the output shaft in opposition to the pressure of one of the springs 62, but provided the torque transmitted does not produce a force sufficient to overcome the pre-compression of the affected spring 62 no relative movement will occur and the torque transmitted will depend entirely upon the slip between the rotor and the housing. Should the transmitted torque exceed the critical value at which the pre-compression of one of the springs is overcome, the rotor will screw along the part 39 thus displacing the surfaces 59 relative to the surfaces 28 to decrease the viscous drag and thus decrease the transmitted torque. Upon further increases in load the coupling will eventually reach a point of minimum overlap between the surfaces 28, 59 at which time the coupling will deliver a maximum torque which will not be exceeded despite higher demands from the machine. The housing is provided with cooling fins 15.

Title: A process and an apparatus for the accelerated weathering of pigment vehicle systems
IPC: G01N17/00
Filed: 1968-08-06
Abstract: 1,241,979. Weather testing pigmented surfaces. FARBENFABRIKEN BAYER A. G. Aug.6, 1968 [Aug.7, 1967], No.37426/68. Heading G1S. The testing of pigmented surfaces e.g. painted surfaces is carried out by "weathering" which means either subjecting the surface to natural or simulated weather conditions. Conventional artificial weathering by exposing the surface to simulated sunlight and watering could take up to 480 hours, whereas it is stated that the present process accomplishes the same degradation in 45 minutes. The surface is degraded under the influence of radicals such as OH supplied by gases or vapours preferably at constant pressure and introduced via a pipe 1 and valve 2 into chamber 4, an electrode 5 energized from a high frequency source 6 producing from the gas radicals which flow through a glass frit diffusion barrier 7 to contact a sample 9 resting on a holder 10. Pipes 15 provided with windows 16 enable the concentration of radicals to be measured by ultraviolet light 17 passing into an absorption line radiation receiver 20 and a mono-chromator 19, an indicator 21 recording the result. Hydrocyl radicals are the most suitable, produced from water of from H 2  O 2 , and it is of advantage to keep the production of radicals constant e.g. by spectroscopic methods or by measuring electron spin resonance and the sample should be kept at a constant temperature.

Apparatus for simultaneously filling recesses in a holder with elongated articles, and used for example in transistor manufacture, comprises a vibrating container with chambers storing bundles of the articles, whereby articles are fed singly through channels into the recesses and means are provided for localising the bundles of remaining articles while the filled holder is removed. Fig. 1 shows bundles 47 of wires located in chambers in plates 33 and 35, each chamber communicating with a channel wide enough to accommodate only one wire, to allow individual wires to fall into recesses in elements contained in holder 19. Plates 33 and 35 are mounted on stand 5 which may be vibrated by springs 11 and intermittent energization of magnets 13. Holder 19 is mounted on plate 7 which may be raised by levers (not shown) against the action of springs 51, to lodge against stop 49. Fig. 4 shows the transistor component part being manufactured, consisting of a metal disc 21 mounted in graphite holder 19, surrounding an insulating member 23 through which penetrates one of the wires 25 from the bundle 47; subsequent thermal treatments unites member 23 with wire 25 and disc 21. The bundles of wires 47 may be tilted obliquely by sliding plate 35 relative to plate 33, which separates the wire ends from the feeding channels so that holder 19 may be removed when filled, without additional wires falling through the channels.
