Filed: 1957-04-13
Abstract: 839,996. Pneumatic gauging-apparatus. T.I. (GROUP SERVICES) Ltd. April 11, 1958 [April 13, 1957], No. 12152/57. Class 106 (2). [Also in Group XXXVI] In a gauging device, a measuring head is maintained at a predetermined distance from the test piece by the operation of a pneumatic servo system. As shown, Fig. 1, a source of air pressure is supplied via a pipe 10 and symmetrical branch pipes 11, 12, containing constrictions 13, 14, to the interiors of bellows 15, 16, the pressure in bellows 15 being reduced by the flow of air through a flexible pipe 17, out of an orifice 18 in the measuring head 2 to impinge upon the test-piece 1. Any deviation from a predetermined distance A between head and test-piece alters the pressure in bellows 15, and a bell-crank lever 4, which is responsive to the difference in the pressures in bellows 15, 16, moves the head 2 to restore the predetermined spacing A, the value of which is set by adjusting the distance B between an orifice 19 in the pipe to bellows 16, and a plate 20. The displacement of the head 2 is indicative of the profile of the test-piece, and may be indicated by a pointer, or electrically from a transducer (not shown) moving with the head. Fig. 2 depicts a similar device in which the measuring head 2 is mounted on the shaft of a piston 23 responsive to the difference in pressures in chambers 15, 16.

Abstract: 585,956. Waterproofing compositions for laminated boards. CAVADINO, C. G. F., CLEAVE, D. P. C., and GYPROC PRODUCTS, Ltd. June 27, 1944, No. 12231. [Class 140] Boards for building purposes composed of or surfaced with cellulosic fibrous material are waterproofed with compositions consisting either singly or in combination of a fluid, a soft-solid or a hard 'mineral non-drying oil residuum obtained from lubricating oils by means of physical processes such as distillation or solvent extraction. Benzine or white spirit is used as a thinner to ensure rapid penetration and fairly rapid drying. The cellulosic materials may be felted wood or other vegetable fibres or chemically or mechanically processed wood pulp and the boards may be either homogeneous or laminated and may contain a core of gypsum. The oil residua may consist of saturated or non- saturated hydrocarbons or their mixtures which remain after a crude petroleum or shale oil has been distilled or extracted to remove the lower and medium boiling fractions, the latter including Vaseline (R.T.M.) and wax fractions. They are usually non-drying oils, and the fluids and soft-solids should register a viscosity by Redwoods, No. 1 Viscometer of 200-800 seconds at 93‹C. The hards have a consistency by B.S.S. No. 803-1938 Penetrometer test of 20-40 units at 25‹C. Where the treated surface is to be painted, the residuum may be blended with a natural rosin or resin, e.g., colophony. The waterproofing composition is applied to the faces and edges of the boards by means of the machine described in Specification 585,955, [Group III].

Title: Applications of nuclear resonance fluorescence of gamma rays to elemental analysis
IPC: G01N23/06
Filed: 1971-04-29
Abstract: 1319376 Element analysis using y-rays AUSTRALIAN ATOMIC ENERGY COMMISSION 29 April 1971 [6 May 1970] 12275/71 Heading G1A A quantitative determination of a particular element in a sample, e. g. the walls 6 of a borehole, is achieved by irradiating the sample with y-rays and detecting the y-radiation resonantly scattered from the element nucleus. The y-radiation from the source 2 is produced by a reaction whose end product is a stable isotope of the element of interest. There are a number of ways of providing a range of y-rays energies from the source around the resonance energy: a. Mechanical motion of the source in a centrifuge b. Heating of the source to increase the Doppler width of the y-rays c. Using a gaseous source d. Using a nuclear reaction i.e. bombarding the source with particles from either a radioisotope source (e. g. an α-emitter) or an accelerator. e. Using a continuous y-ray spectrum (e. g. Bremsstrahlung). An arrangement, using a gaseous source 1, for borehole logging has a shield 8 to prevent radiation reaching the detector 7 direct from the source. The detector is either a scintillation crystal or a solid-state Ge (Li) detector. Another detector/ shield combination may be disposed at the other side of the source. In another application, Fig. 5 (not shown) y-rays of the required resonance energy which are not resonantly scattered by the sample (17) pass directly therethrough and impinge on another block containing the element of interest. Resonantly scattered y-rays from this block are received on a detector (18).

Title: Improvements in resilient transmission mechanisms
IPC: G05G7/14
Filed: 1952-05-15
Abstract: 726,423. Dashpots. WARMOES, J. J., and CLOSKIN, L. A. A. J. May 15, 1952 [June 16, 1951], No. 12360/52. Class 108 (3). [Also in Group XXXVII] The invention relates to mechanism for transmitting movement of one moving member 2 to a second member 7, which it is desired to move in the same direction, with a delay determined by the magnitude of either the movement or the force. According to the invention, the mechanism comprises a spring 13 interposed between the two members 2, 7, a piston 6 attached to the member 7 and working in a cylinder 8 which is substantially air-tight, so that on initial movement of the member 2, movement of the member 7 is restrained by vacuum in the cylinder 8, until the force built up in the spring 13 is sufficient to move the piston away from the closed end of the cylinder 8 to a point where it allows air to enter the cylinder. In the construction shown, a slot 10 is formed in the wall of the cylinder 10. The vacuum which develops in the cylinder 8 is broken when the top edge of the piston reaches the top end of the slot 10. The force applied to the member 2 is then fully applied to the piston rod 7 which may transmit it to a desired member either directly or through a mechanical or electrical relay.

Veneer is made resistant to humidity change by saturating it with moisture and pressing and drying it between two plates, at least one of the plates having a roughened surface so that the fibres on that side of the veneer are fixed in position against the influence of shrinking forces during drying. The veneer is "loosely" peeled, i.e. the compression during peeling owing to the pressing beam is only from 2-7% so that voids or cheeks are formed on the " loose " side, and the " tight " side is sanded to leave a thin flexible void-free layer on that side. If desired, the veneer is cut into the dimension of floor tiles and the tiles are immersed in water at 60- 90‹ C. for a period of 2-24 hours. The roughened surface on one of the pressing plates may be obtained by interposing a sheet of metal gauze between the plate and the " loose " side of the veneer so that the veneer fibres are fixed at the contact lines between the gauze and the tiles but are free to settle at the interstices. The pressure on the plates is about 56 lb/square inch and the drying temperature is of the order of 120‹ C.
