Title: Apparatus and method for making large thin concrete panels in seamless reinforced plastic moulds
Inventor: KREIER GEORGE JULIUS JR
IPC: B28B7/34
Filed: 1967-11-28
Abstract: 1,205,615. Moulding concrete. G. J. KREIER. 28 Nov., 1967, No. 54044/67. Heading B5A. [Also in Division E1] A method of constructing a large, thin concrete panel comprises the steps of building a prototype mould and coating it with a release agent, forming a glass fibre master pattern from said prototype mould and coating it with a release agent, forming a flexible glass fibre production mould from said master pattern and coating it with a release agent, positioning reinforcing material in said production mould, pouring concrete into said production mould, levelling the upper surface of said concrete and removing said formed concrete panel from said production mould without dismantling said mould. The concrete building panels 22, Fig. 6, are cast in the production mould 18 which comprises one or more layers of glass fibre cloth saturated with a catalysed polyester and having a surface gel coat containing a hydrophilic fibrous filler and a styrene polyester resin. The master mould is of similar construction to the production mould which is made on a prototype mould which is made by hand from material such as clay, wood, plaster, plastics and metal. The master mould 10, Fig. 3, is made sufficiently rigid by the use of wood stiffeners 13 and is surrounded by a frame 11, 14, 16 for shipment to the site. The production moulds 18, Fig. 5, produced at the site, are each provided with stiffeners 13 and with corner drainage channels. Before concrete is poured into a production mould reinforcing rods or wire mesh are laid out therein together with electrical fittings, conduits, cables and water pipes and weld plates. The concrete is poured in and smoothed with a vibrating screed. After curing and hardening a vacuum lifter removes the moulded panel; such removal being facilitated by flexing of the mould. Only three different master patterns are required for the walls of a rectangular house, the various panels being assembled by welding the weld plates together.

Title: Compressor unloader and check valve unit
IPC: F04B49/035
Filed: 1973-11-22
Abstract: 1393339 Controlling compressors J L KRECHEL 22 Nov 1973 54192/73 Heading F1N [ Also in Divisions F2 and G3] An unloader valve for a compressor an inlet 5 connected to the compressor outlet, or outlet 7 to an accumulator or fluid pressure operated device and an exhaust post 9, a check valve 63 between the inlet and outlet and a valve 15 between the inlet and exhaust sensitive to pressure at the outlet 7. This pressure, fed via a ball valve 39, acts on a piston 21 connected with the valve 15 to open the valve when the pressure has risen to a pre-set level sufficient to lift the ball valve against the adjustable loading provided by a helical spring 59 which operates through a rod 42. The outer end of the rod has a ring 61 for manned operation. A pivoted locking member 69 can be placed in one of three positions to operate the valve in one of three modes. The locking member may engage the underside of the ring 61, after manual withdrawal of the rod 42, to remove the loading from the ball valve 39 which will open under the influence of pressure at the outlet 7 to operate the piston 21 and valve 15 to unload the compressor. If the locking member engages the inside of the ring the ball valve will be locked thus disabling the valve 15  which will remain closed, any pressure in the cylinder 29 leaking away to atmosphere between the rod 42 and the member 47. In the third mode the locking member is pivoted out of engagement with the ring so that the ball valve opens to unload the compressor only when the predetermined pressure is reached at the outlet 7.

Abstract: 1,199,645. Photographic silver halide emulsions. EASTMAN KODAK CO. Dec.1, 1967 [Dec.2, 1966], No.54737/67. Heading G2C. In the preparation of a photographic silver halide emulsion, the silver halide grains are precipitated in the presence of a rhodium salt and thereafter a stabilizing amount of cadmium bromide is added. A silver halide solvent such as a water-soluble thiocyanate or an organic thioether may be present during precipitation or digestion of the silver halide grains. The emulsion may be chemically and optically sensitized and coated on to a support. Developing agents such as hydroquinone and 1-phenyl-3-pyrazolidone may be present in the emulsion or in a contiguous layer. Rhodium salts specified are rhodium ammonium chloride and rhodium mono-, di- and trichlorides. The cadmium bromide may be added just before the emulsion is coated and its effect is compared with that of cadmium chloride and potassium bromide. The use of cadmium bromide prevents the increased contrast obtained with the rhodium salt being lost on storage.

Abstract: 1457830 Remote detection of pollutant gases NATIONAL AERONAUTICS & SPACE ADMINISTRATION 24 Dec 1974 [27 Dec 1973] 55665/74 Heading G1A Apparatus for this comprises a laser 11 for causing the gases to fluoresce, means 15 for absorbing the fluorescence of a particular fluorescent gas from part of the fluorescence while passing fluorescence from other pollutant gases and means 21 responsive to the difference of the fluorescences emerging from 15 and non-absorbing compartment 16, giving a signal indicating the concentration of said pollutant gas. Fluorescence enters detector 12 through optional filter 13 rejecting the laser wavelength. If nitric oxide is to be monitored compartment 15  contains nitric oxide which may be mixed with nitrogen at atmospheric pressure and compartment 16 contains nitrogen or helium or a vacuum. Further compartments may be used for other pollutants. Oscillator 24 of fundamental frequency f o , about 100 Hz pulses the CO 2  laser via harmonic generator 29 at 5f o  and supplies synchronous motor 23 rotating chopper 22 so that radiation through compartments 15, 16 is alternately focused by lens 17 on detector 21, which thus receives a triangular wave envelope of amplitude proportional to the absorption by 15. The detector output is amplified by 25 demodulated and made into a triangular waveshape by eductor 26 and made sinusoidal by tuned amplifier 27. Thus synchronous detector 31 supplies integrator 32 which gives a D.C. voltage of magnitude proportional to the amount of nitric oxide to recorder 33. Eductor 26 indicates the delay of the received pulse relative to that from oscillator 24, thus indicating the distance of the pollutant. It may be omitted and the laser operated continuously.
