Title: Improvements in dental models
IPC: A61C13/00
Filed: 1932-07-27
Abstract: Dental models are made from a composition comprising at least 75 per cent of a semi-hydrate of gypsum the weight by volume of which "loosely put in" is above 0,9 gms. per c.cm., and "shaken in" above 1,45 gms. per c.cm., the "strewed in quantity" of which, until a paste capable of being poured is attained, is at least 230 gms. per 100 c.cms., and its "thickest consistency" is 300 gms. per c.cm. These terms are defined in the Specification.  In an example 95 parts by weight of a plaster of paris having properties falling within the above definition are mixed with 0,05 parts of borax, 0,5 parts of potassium sulphate, 1,5 parts of pulverized marble and 3 parts of pulverized quartz.  When 330 gms. are mixed with 100 c.cms. of water, it sets in 1/2 hour and after 1 hour has a Brinell hardness of about 7 kgms. per sq. mm.

Title: Improvements in or relating to Telescopic Dampers
Inventor: NICHOLLS LAWRENCE GEORGE
IPC: F16F9/088
Filed: 1967-05-08
Abstract: 1,185,699. Hydropneumatic shock absorbers. GIRLING Ltd. 2 May, 1968 [8 May, 1967], No. 21350/67. Heading F2S. In use of a telescopic damper of the form shown, an open conduit 21 interconnects two liquid-filled spaces 16 and compressed gas 17 is trapped in the space bounded by the conduit 21, the cylindrical wall lining 18 and the liquid-gas interface. In storage, however, gas may escape to the cylinder space 16 above the conduit, and to prevent this occurring the invention provides a damper in which the conduit 21 is sealed in manufacture, e.g. by a frangible diaphragm 30. The seal is automatically broken, by hydraulic pressure, when the damper is put into use. The conduit 21 is flexible so that the device may be used in orientations other than the vertical one shown, the flexibility of the conduit ensuring that its lower end remains below the liquid-gas interface even when the damper axis is far from vertical. The piston 11 contains valve-controlled ports (not shown).

Title: Improvements in or relating to electric power cables
IPC: H01B7/22
Filed: 1946-07-17
Abstract: 614,508. Electric cables. MOLLERHOJ, J. S., and STIGSGAARD, S. July 17, 1946, No. 21410. Convention date, Oct. 17, 1945. [Class 36] In an electric power cable having an impervious lead or similar sheath, the crosssection of which includes relatively sharply curved portions and intermediate flat portions which provide diaphragm surfaces externally supported by resilient binding so that they may yield to meet pressure variations within the sheath, the resilient binding comprises at least one winding element having varying rigidity along the periphery of the sheath, the rigidity being a maximum at the diaphragm surfaces. Fig. 2 shows a cross-section of one embodiment of the invention. Three conductors 10 whose axes lie in a single plane are each surrounded by insulation 12, around which is a lead sheath 14, the flat portions of which form the diaphragm of the cable. The hollow spaces are filled with oil 15, and the seams 16 of the lead sheath are at the centres of the curved surfaces. Surrounding the lead 14 is a linen winding 18 and two tape windings 20. Arranged over the tapes 20 and wound in opposite direction thereto is a winding of flat wires applied double and so that each wire is twisted through half a revolution about its own longitudinal axis each time it extends over a diaphragm surface. The wires thus lie with their flat surfaces against the cable at the curved parts and make edge contact at the flat parts, more particularly at the centre of the diaphragm surfaces. Specification 542,473 is referred to.

Title: Swinging buck press
IPC: D06F71/06
Filed: 1935-07-29
Abstract: 450,905. Ironing-presses. MATTHEWS, A., 3064, Victoria Boulevard, Cincinnati, Ohio, U.S.A. July 29, 1935, No. 21552. [Class 138 (ii)] The buck 11 is slidably mounted in a support 14 pivoted to two pairs of parallel links 12 which are pivoted to the stationary frame 13, one pair of links being positioned at each side. A plate 25 is secured to one member of each pair of links and is provided with a cam slot 24 in which followers 22 carried by a piston-rod 20 engage. During the initial upward movement of the piston-rod the followers traverse the horizontal portion of the cam slots and swing the links counterclockwise so that the buck moves from the loading position shown to one wherein it registers with the stationary press head 10. During further upward movement of the piston-rod the followers idly traverse the vertical portion of the cam slots and the piston-rod engages a stem 16 projecting downwardly from the buck so as to raise the latter into pressing engagement with the head. The buck structure is counterweighted by a weight 31 secured to a shaft 32 carried by the stationary frame and linked to the arms 12. The buck frame is latched in the position wherein the buck registers with the head by the engagement of pins 40 in notches 37 in spring-actuated arms 41 pivoted about a shaft 38. The latch is automatically released during the descent of the piston by the engagement of a projection 43 on the piston-rod with an arm 42 on the shaft 38. The supply and exhausting of the fluid pressure to and from the cylinder 19 in which the piston works is controlled by valves housed in a casing 29 and manually operated by a lever 30. The whole device is substantially enclosed in a casing 44.

Title: Improved hydro-pneumatic vibration damper for washing
IPC: D06F37/20
Filed: 1963-05-30
Abstract: 996,878. Hydro-pneumatic shock-absorbers. FICHTEL & SACHS A.G. May 30, 1963 [June 2, 1962], No. 21711/63. Heading F2S. A hydro-pneumatic shockabsorber for a washing- machine comprises a valved piston 3 which works in a cylinder 1 filled with a volume of fluid 10 in contact with a supplementary volume of gas 11 which is uncompressed in the no-load condition and a piston-rod 2 which extends through a seal 7. In an alternative arrangement, the air volume still remains at the upper end of the cylinder, but the piston-rod projects through a seal 7 at the lower end of the cylinder. The volumes of the liquid and gas are such that the damping resistance of the piston 3, for small displacements from the central position towards the gas volume, is greater than the elastic resistance of the gas volume so that small vibrations due, e.g. tc the critical speed of a rotat able washing-machine container, are not transmitted to the washing - machine housing.
