Title: Improvements in or relating to apparatus for adding solutions of chemicals to the feed water of steam generating plant
IPC: B01J4/00
Filed: 1932-08-13
Abstract: 392,031. Preventing incrustation and corrosion. SCHULZ, P., 52, Borussiastrasse, Tempelhof, Berlin. Aug. 13, 1932, No. 22774. [Class 123 (i).] In apparatus for supplying chemical solutions to feedwater, the solution 12 is contained in the upper part of a vessel 4, and the lower part communicates by a pipe 2 with a funnel inlet 3 in the feed pipe 1 directed against the water flow. Pressure thus created in the space 11 is transmitted through pipe 6 to the surface of the solution 12, which is thereby forced through a delivery pipe 7 into the feed pipe. The solution is supplied from a reservoir 14 by a pump 15. The pipe 7 contains an enlargement 8, the air in which, when feedwater is not flowing, extends upward into the bend of the pipe 7 and prevents any passage of solution. When feedwater is flowing, pressure transmitted to the surface of the solution 12 forces it through pipe 7, displacing the air into the enlargement 8. The apparatus prevents diffusion of the solution into the feedwater when not required.

IPC: G06F19/00
Filed: 1968-05-14
Abstract: 1,221,891. Bowling scorer. AMF Inc. 7 May, 1969 [14 May, 1968], No. 22809/68. Headings G4A and G4D. In a bowling scoring system a frame-by-frame history of the game, with progressive player and team scores, is displayed on a cathode-ray tube, Fig. 3, there being one tube per team. A 61 step computer programme is described for accepting the various constants, such as handicaps and blind scores, to perform the necessary score calculations in accordance with the ABC Rules for bowls. A special purpose computer is outlined using a magnetostrictive circulating delay line store of sufficient length to store the outcome of each ball bowled, and the progressive player and team scores, for a complete game. Normally the contents of the whole delay line are displayed, as in Fig. 3, but the programme does incorporate the "superstition factor" so that during a run of successive strikes some frames are not displayed. The C.R.T. displays use a basic figure eight format for each number, and data for the two tubes is interlaced in the delay line so that whilst one beam is being positioned, the other is writing. The contents of the delay line may be read out to a printer or to a tape recorder.

Title: Random access semiconductor memories
IPC: G05F1/56
Filed: 1975-05-23
Abstract: 1502925 Data store INTERNATIONAL BUSINESS MACHINES CORP 23 May 1975 [19 June 1974] 22913/75 Heading G4C A monolithic data store includes a matrix array of bi-stable memory cells producing output signals indicative of stored data, the signals having a voltage range whose midpoint shifts with respect to an absolute value as a function of temperature, and a bias circuit, Fig. 3, arranged to provide a reference voltage VREF equal to the midpoint of the cell voltage range which tracks the midpoint as it shifts due to temperature effects. The memory, Fig. 2, is conventional, each cell includes a bi-stable circuit formed of two double emitter transistors T21, T22 connected as shown to a pair of bit lines 301, 302 which are connected to a sense amplifier SA1 which acts to write into and read the storage cells. The cell transistor T21 combines with transistors T41, and T31 in the sense amplifier to form a current switch. When not used for read or write operations the cells are quiescent, a small current flowing through the conducting transistors T21 or T22 to current source VEE. When a cell is addressed the appropriate word line WSL3 is made less negative using driver WD. To write data transistors T31, T32 are biased off and one of transistors T41, T42 is biased "off" and the other "on" by input signals wr1, wr0. The cell transistor T21, T22 corresponding to the non-conducting transistor T41, T42 switches on and data is written in. To read data the bias VREF supplied to the sense amplifier is more positive than in the write mode and is equal to the midpoint between the voltages VC and VD at the modes of the storage cell. Transistors T41, T42 are biased off so that the transistor T31, T32 corresponding to the non- conducting transistor T21, T22 in the cell will conduct and the other transistor T31, T32 will not conduct. The resulting voltage drop across resistor R31, R32 allows the cell to be read. However if the voltage VREF is not equal to the midpoint be ween VC and VD faulty reading may result. The bias circuit, Fig. 3, includes elements similar to those in the memory cells and driver circuit and is arranged to produce voltages VCC and VDD which accurately follow the cell voltages VC and VD as they vary with temperature and an output VREF<SP>1</SP> which accurately tracks the midpoint between VC and VD. The transistors T51-T53 merely act to produce a voltage VREF = VREF<SP>1</SP> but with a low output impedance. Specification 1,348,327 is referred to.

Title: Improvements in tap changing gear for electric transformers
IPC: H01H9/00
Filed: 1934-08-08
Abstract: 440,280. Regulating switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and MORRIS, G. G., c /o General Electric Co., Ltd., Witton, Birmingham. Aug. 8, 1934, No. 22952. [Class 38 (v)] In on-load tap-changing gear for electric transformers in which a tap-changing selector switch 22, Fig. 2, is associated with two co-operating switches 2 to avoid circuit interruption at the selector switch, each switch 2 is positively operated by a cam 21, Fig. 1, and includes a pair of movable contacts 1 that break circuit by simultaneously moving away from each other. The cam 21 acts on a bell crank lever 17, 19, which actuates a rod 15 connected to a lever 12, 14 which moves up and down a link 11 connected to the common pivot 9 of two toggle links 8 connected at their outer ends to the levers 5 carrying the contacts 1. The other co-operating switch 2 is actuated similarly by a bell-crank lever which engages the other side of the same cam 21. The selector switch comprises a rotatable shaft 24 carrying two contact arms 22 which engage contacts 23 on rods 27 arranged in a circle round the shaft 24. The contacts 23 are arcuate and in electrical connection with their rods 27 and each rod is connected to a tapping, and the arrangement is such that before one arm 22 leaves a contact 23 the other arm 22 engages the next contact 23. The arms 22 are connected to opposite sides of a choke through the two cam-operated switches, the centre of the choke being connected to the main circuit. The selector switch and the co-operating switches are driven simultaneously from a master wheel which drives two Geneva mechanisms, one serving to rotate the shaft 24 through gearing 36 and the other, shown in Fig. 1, serving to drive the cam 21. The arrangement is such that a cam operated switch 2 opens the corresponding selector arm 22 then moves one step from a first tapping on to a second tapping, and the switch 2 then closes. A voltage is then obtained intermediate between the first and second tappings. Further operation causes the other switch 2 to open, then the other arm 22 to move on to the second tapping, and the switch 2 to close. The voltage corresponding to the second tapping is then obtained.

Abstract: 472,087. Electric control systems. LANDIS & GYR AKT.-GES. Aug. 21, 1936, No. 23042. Convention date, Sept. 7, 1935. [Class 40 (i)] In a system for controlling the temperature of a room or the like by intermittently switching a heating plant on and off, a time switch 4, temperature regulator 5, transformer 6 and relay 8 are connected across supply mains 1, 2. The regulator 5 is placed outside the room, and contains a bimetallic strip 9 in series with contacts 10 and a heating resistance 11. The contacts 10 are closed by the strip 9 when cold, the heater 11 is energized and the strip 9 then opens the contacts. The strip 9 cools at a rate dependent on the surrounding temperature and again closes the contacts. An intermittent energizing of the relay 8 thus occurs, which effects an intermittent switching-on of the heating apparatus 7, the ratio of switching-on to switching-off periods depending on the external temperature in which the regulator 5 is placed. The temperature in the room remains constant. The heating effect of the resistance 11 may be varied by a small regulating resistance in series.

Abstract: 240,636. Gerdts, G. F. Oct. 1, 1924. Thermometers.-For indicating critical temperatures in such operations as annealing, casting, &c. solid bodies or test pieces which fuse at the predetermined temperature are brought into contact with the heated object, so that the surface of the latter when it has attained the predetermined temperature is with clearly visible traces of the fused surface of the test piece, which may consist of or contain colouring matter other than metallic salts. The test pieces may be in the form of bars or rods divided into sections of say 1 cm., one section being fused away at each test. For testing the temperature of a fusing, mass in a crucible, a rod of test material long enough to reach the bottom of the crucible is thrust into the mass, the temperature at different distances from the bottom being indicated by observing the partial fusing of the test material at different points. Alternatively, metallic test pieces may be placed on the surface of the metal in the crucible and allowed to fuse to indicate the correct time for pouring the metal. In this case the test piece may consist of metal or alloy capable of combining with the metal in the crucible to modify its properties, the weight of the test piece bearing a definite relation to that of the metal.
