Title: Improvements in or relating to saw frames for the sawing of stone
IPC: B28D1/06
Filed: 1920-04-17
Abstract: 163,883. Criara, C., and Paolini, M. April 17, 1920. No Patent granted (Sealing fee not paid). Sawing. - The saw frame of a machine for sawing stone or other material is given a horizontal travel with a lift at each end. For this purpose the frame 11 is supported by pairs of links 5, 6, pivoted to triangular members 2 suspended from shafts 22, the blades 12 being fixed in the frame by keys 13. The frame is reciprocated by a driving-shaft 25, and the vertical feed of the work-table 15 is effected by means of ratchet-wheels (not shown) on the shafts 22 actuated by pawls carried by the frame, together with worm and screw gearing as shown. Fig. 1<a> shows diagrammatically the manner of supporting the frame, and Fig. 1 an alternative arrangement, the letters o, o<1>, o<11> indicating fixed supports.

Title: Improvements in and relating to lubrication systems
IPC: F01D25/20
Filed: 1947-04-22
Abstract: 623,256. Lubricating. BRITISH THOMSONHOUSTON CO., Ltd. April 22, 1947, No. 10688. Convention date, April 23, 1946. [Class 12 (iii)] In a oil system for a steam turbine 1, oil is supplied at a high pressure to a hydraulic governor 4, and at a low pressure to the turbine lubricating system, the difference in pressure being utilized to drive a booster pump 22 for priming the main centrifugal oil pump 12 which is coupled to an extension 14 of the turbine shaft 2. The hydraulic governor 4 controls a motor 6 which positions the turbine inlet control valve 7. Oil from the outlet 17 of pump 12 enters conduit 18 where the flow is divided, one part entering conduit 5 for operation of the governor 4 and the other entering conduit 21 to drive a turbine 24. Oil returns from governor 4 to the inlet 16 of pump 12 via conduit 11. A check valve 20 is provided in conduit 18 and a pressure regulating valve 19 incorporated in conduit 5. The turbine rotor 24 and a centrifugal pump impeller 23 are mounted on a common shaft 25. Oil from the outlet 29 of the turbine 24 enters a cooler 33 via conduit 32 from where it passes through conduit 3 to the turbine I for lubrication purposes. The oil is returned to a reservoir 9 via conduit 10. A pressure release valve 36 is incorporated in conduit 3 to maintain the lubricating oil at a constant pressure. A byepass conduit 38 is arranged in parallel with the turbine 24 and adjustment of throttle valves 39, 40 in conduits 38, 21 control the speed of turbine 24. A conduit 30 containing a check valve 30a connects the outlet 27 of pump 23 with the inlet 16a of the main pump 12. Oil is admitted to the pump 23 from reservoir 9 via inlet 26. In starting the turbine 1, the system is initially primed by a second auxiliary centrifugal pump 41 driven by an electric motor 42 and supplying oil from the reservoir 9 through conduit 47 to conduit 21. A check valve 48 is incorporated in conduit 47 and when the pressure in the latter is exceeded by that in conduit 21, the closing of the valve flap 48a causes contact arm 50, which is secured to the flap, to move away from the stationary contact 52, thus breaking the circuit to motor 42. A spring 50a biasses the contacts to a closed position so that motor 42 will be energized whenever the pressure in conduit 21 falls below a preselected value.

Title: Improvements in or relating to apparatus for evaporating crystalline solutions
IPC: C13B30/02
Filed: 1965-03-16
Abstract: 1,095,622. Evaporation of solutions; production of crystals. J. M. MALEK. March 16, 1965 [March 16, 1964; Sept. 28, 1964], No. 11158/65. Heading B1B. Crystals are produced from solutions of crystalline materials by feeding the superheated solution through inlets 55 into a column where flash vaporization of part of the solvent takes 'place and a mixture of solution and bubbles of vapour rises through cylindrical plates 50, which prevent the coalescence of the bubbles, to a vapour-separating chamber from which the vapour is withdrawn through outlet 57. The solution then flows down the central tube 47 into chamber 53 where a fluidized bed of crystals is formed. The solution, with smaller crystals in suspension, recirculates up the evaporator column 46. Larger crystals sink to wards outlet 54, from which they can be removed. The apparatus is kept filled with solution up to level 58. Mother-liquor is discharged through outlet 56. A heater may be provided for the column below plates 50 at such a level that vaporization of the liquid at the heating surface is prevented by the hydrostatic pressure due to the head of liquid. Air or gas, saturated with the vapour of the solution being treated, may be bubbled into the solution as it rises in the column. Apparatus is also described wherein the recirculation column 47 is outside the evaporator column. 1,095,628. Continuous mixing apparatus. BUSS A.G. March 2, 1966 [March 31, 1965], No. 9085/66.

Abstract: 1392787 Multiplex systems SIEMENS AG 12 March 1973 [24 March 1972] 11719/73 Heading H4R In a carrier frequency transmission system in which the frequency bands converted in modulators at one modulation level are combined to form a frequency band for the next modulation level and in which the modulators are followed by filters to remove unwanted modulation products, some of the modulators are followed by two or more filters in cascade, the last filter being a band pass filter defining the frequency bands for the next stage of modulation while the preceding filters are high pass, or low pass, whose cut off frequency lies at the lower, or upper, limit of the band supplied by the previous modulator, or modulators. Fig. 1 shows one arrangement in which each filter Fl to F4 is a low pass filter of cut off equal to the upper frequency supplied by the respective modulators M1 to M4 and in which each filter receives the output of its respective modulator and all filter outputs lying within the pass band of the filter. The filter F5 being band pass covering the total band covered by the modulators M1 to M5. In an alternative arrangement, Fig. 2 (not shown), the low pass filters (F1 to F4) are connected to receive only the output of the respective modulators and the modulator M5 output and the outputs of the filters Fl to F4 are commoned at the input of an isolating amplifier V feeding the band pass filter F5. A further alternative arrangement, Fig. 3 (not shown), uses one of more low pass filters common to two or more modulators.
