Title: Improvements in or relating to fluid compressors
IPC: F25B31/00
Filed: 1928-12-03
Abstract: 305,123. Sulzer FrÞres Soc. Anon. Jan. 31, 1928, [Convention date]. Oscillating cylinder pumps.-A piston pump comprises a casing 1, Fig. 1, receiving a pendulum or other movement at variable velocity, and an inertia mass 4 within the casing disposed so as to receive little or none of the movement. e.g. by mounting the mass loosely on the hollow shaft 3 on which the casing oscillates, the relative movement of the two parts effecting the working stroke being at an angle to the piston motion. Fig. 1 shows the compressor cylinder 7 secured to and moving with the casing, while the piston carries a roller actuated by a cam 6 on the mainly circular inner surface of the mass 4, the return stroke being effected by a spring. A pair of lateral springs connected to stops 22 tend to hold the cylinder in its middle position. The cam surface may be directed outwards instead of inwards as shown. The piston may alternatively be provided with a connecting-rod pivoted to the mass 4. Fig. 5 shows a modification in which the inertia mass is constituted by the bob 26 of a pendulum pivoted at the centre of rotation 28 of the casing 24, which contains a pair of cylinders 25, the pistons of which are actuated through levers 30, 31 by a cam 29 on the pendulum rod.

Title: Pump support
IPC: F16F9/00
Filed: 1974-08-19
Abstract: 1464116 Machine supports; hydraulic dampers COMBUSTION ENG Inc 19 Aug 1974 [22 Aug 1973] 36429/74 Headings F2X and F2S A support arrangement for a pump, in particular the coolant pump of a nuclear power plant, which permits movement of the pump owing to thermal effects and can withstand sudden shock loading, includes four vertical posts 26 beneath the pump 20 pivotally attached at their upper ends to the pump 20 and at their lower ends to a stationary structure (not shown) which is designed to withstand earthquake tremors, and four horizontal posts 28, 30 pivotally attached at one of their ends to the pump 20 and at their opposite ends to the stationary structure. Vertical posts 26 and horizontal posts 28 are pivotally attached to a downwardly extending skirt 24 integral with the pump motor housing 23 and horizontal posts 30 are pivotally attached to the pump motor housing 23. The thermal movement of the pump 20, due to the reactor vessel (10) (Fig. 1, not shown) becoming hot as the plant is initially started, is generally in a radial direction of the vessel (10) and thus the pump 20 will move substantially in the direction of arrow 22, and the four horizontal posts 28, 30 extend in a direction transverse of the arrow 22. A pair of snubbers 32 extending in the direction of arrow 22 are pivotally attached to both the motor housing 23 and the stationary structure. The pivotal attachments may comprise spherical bearings (34) (Fig. 3, not shown). As shown in Fig. 4, each snubber 32 comprises a cylinder 46 containing a piston 42, the rod 40 of which is pivotally attached to the motor housing 23 while the cylinder 36 is pivotally attached by a rod 44 with the stationary structure. Hydraulic lines 58, 60 connected to the opposite ends of the cylinder 46 are also in fluid communication with a chamber 48. A pair of valves 50, 52 are biased away from their respective valve seats 53, 55 by means of a spring 54. The system is completely filled with a liquid. Thus, when the pump 20 is subjected to slow movement caused by thermal growth, liquid can flow from one side of piston 42 to the other through chamber 48. In the event the pump 20 is subjected to abrupt forces, as from an earthquake, tending to move the piston 42 one way or the other, the sudden surge of pressure in pipe 58 or 60 will cause valve 50 or 52 immediately to close by overcoming the force of spring 54. In either event, the snubber 32 becomes a rigid supporting member. If the earth tremors exert forces on the pump 20 in vertical directions or other horizontal directions, either the vertical posts 26 or the horizontal posts 28, 30 serve to hold the pump 20 securely in place. A reservoir 56 in communication with the chamber 48 serves to compensate for the difference in volume on the respective sides of piston 42 because of the presence of rod 40.

Abstract: 522,641. Magnetic dust cores. STANDARD TELEPHONES & CABLES, Ltd., (Polydoroff, W. J.). Dec. 16, 1938, No. 36706. [Class 38 (ii)] In magnetic dust cores for high or audio frequency work, the necessary separation between the particles of ferro-magnetic material is effected by finer grains of powdered paramagnetic material of high specific resistance such as Fe 3  O 4 , Ni 3  O 4 , CuO. Fe 2  O 3 , NiO. Fe, O 3 ; so as to avoid undue reduction in the permeability of the core. The proportion of paramagnetic material may vary between 10 per cent. and 47¢ per cent. in accordance with frequency, and for the higher frequencies up to 5 per cent. of an insulating binder such as phenolic resin which is subsequently polymerized may be used. For the lower frequencies binder is dispensed with, core formation being effected under a pressure exceeding 75 tons per square inch. In order to decrease resistance along the direction of the magnetic circuit, the particles may be partially fused together by the application of electric currents in that direcion.

Abstract: 1526053 Shell and tube vapourizer J E POTTHARST 5 Sept 1975 36709/75 Heading B1B In a vapour compression distillation apparatus liquid (e.g. salt or brackish water) is maintained and heated in the lower end of a tube and shell vapourizer, the upper level of said liquid being above the lower ends of the tubes (e.g. at level 30). Frothy liquid and vapour ascends the tubes and passes laterally across an upper tube plate over an edge and downwardly through passage 19, whereupon the vapour is removed upwardly (e.g. through a demister) to a pump 25. The vapour is there compressed and fed into the shell to heat the tubes and to condense. The condensate is discharged in heat exchange with the incoming feed. The liquid in passage 19 continues downwardly from the ascending vapour and falls back into the liquid at the end of the tubes (i.e. at level 30). The vapourizer may comprise tubes arranged in series.

Abstract: <FORM:0781493/III/1> A gluing-machine having rotatable gluing rollers has a glue tank with a rotatable stirrer mounted on the machine with the stirrer shaft coupled to a shaft of one of the gluing rollers whereby rotation of the gluing roller effects mixing of glue ingredients in the glue tank.  Two gluing rollers 15 are mounted in bearings 14 on end frames 10 joined by a transverse member 11 supporting a tray 12.  Each roller has a glue trough 16.  The shaft of the lower roller has a clutch 44b which co-operates with a clutch 44a on a shaft 40 carrying stirrers 42 rotating in a glue tank 31. The tank has at each end a mounting member 35 which is flat at the bottom and has two apertures so that it can be slid along two supporting rollers 29 mounted in bosses 19 on a plate 17 on frames 10.  A lid 21 having a grille 23 is mounted on two supports 20 mounted in bosses 18 on the plate 17.  Powder glue ingredients are introduced into the tank through the grille and liquid ingredients through the gap between the lid and end wall of the tank when it is being positioned on the bars 29.  Rotating the idlers causes the stirring shaft to be driven and the glue stirred in the tank ready for use by removing the tank from the machine.  The tank may be a permanent part of the machine with a control for the clutch and with a valve for running off the glue to a smaller receptacle to refill the troughs 16.  The upper gluing roller 15 is vertically adjustable with respect to the lower roller.

Filed: 1974-08-23
Abstract: 1457604 Data processing system INTERNATIONAL BUSINESS MACHINES CORP 23 Aug 1974 [6 Oct 1973] 37112/74 Heading G4A A data processing system including a store and a data flow path including a number of storage elements between which data is transferred during the execution of program macroinstructions, is arranged to execute the program macro-instructions selectively under the control of normal and diagnostic (tracing) microprograms which execute the program instructions, the diagnostic microprogram establishing in the store a number of storage locations each corresponding to one of the storage elements, and maintaining the contents of the storage locations identical to the contents of the corresponding storage elements. The arrangement allows microprogram operations to be checked using a tracing microprogram, i.e. a diagnostic program at the same level as the program being checked. In normal operation macroinstructions are executed by stored microinstructions which control the operations of the various units in the system which may include the store, an ALU, an accumulator register, various address register, and a local store. A diagnostic (tracing) microprogram which may be read into the store from a disc may also control the system. The tracing microinstructions directly control the system hardware to simulate the execution of a program macroinstruction by maintaining in the store a copy of the system hardware. Storage locations are assigned to the various hardware units and their contents are maintained so as to simulate the contents and/or states of the corresponding hardware units when the latter execute the macroinstruction. In this way the store always contains data reflecting in great detail the state of the system and this data may be accessed for analysis. The system may include a display device and keyboard to enable required data to be displayed. The tracing program is arranged to stop in response to certain conditions within the system and to display the stored data and may co-operate with an operator by displaying a requirement for action by the operator who may then key in an instruction, e.g. to display certain data, to alter certain data, or to protect certain storage locations. This last facility may be used to protect an old program from alteration by a new program being tested, a protected storage location violation causing the system to halt and display data.
