Title: Improvements in the construction and arrangement of tubes for radiators
IPC: F28F3/00
Filed: 1919-09-02
Abstract: 141,596. Mosses, A. J. H., Searle, C. and Sceales, K. L. Sept. 2, 1919. Radiators; pipes and tubes. - Radiators are built up of corrugated tubes or plates 3 which are formed of single sheets of metal which are in the first place bent to the shape shown in Fig. 2, a metallic core or separator 5 being used to form the water space and the edges of the tube being left free until the tube is passed through a pair of corrugated rollers. These rollers are formed with side corrugations at a greater distance from the centre than the main ones which bend the tube 3 and the separator 5 for acting on the edges 2, 4. The separator is removed by opening up the edges 4, and the edges 4 are preferably soldered together after the tubes are assembled to form the radiator together with hollow tubes 12 for the passage of air or other cooling medium. The tubes 12, 3 are soldered together, thus forming a watertight connexion between the inner ends of adjacent tubes 3 at the top of the radiator. The outer ends of the tubes are bent up at 13 and secured, by solder.

Title: Improvements in surgical douching apparatus
IPC: A61M3/02
Filed: 1919-09-02
Abstract: 140,316. Arnett, F. R. Sept. 2, 1919. Irrigators and like appliances.-In return-fluid apparatus primarily intended for treating the vagina, the tubes are so arranged that either the supply or the overflow may be stopped indepen. dently, or they may both be kept open together. In addition, a non-conducting obturator is em. ployed, so that very hot fluids may be employed without causing discomfort. The supply tube 6 terminates in a spherical nozzle 13 having a ring of perforations some distance from the extremity, which is solid. It projects beyond the spherical enlargement 2 of the return-tube 1 and is kept in position by lugs in the mouth of the enlargement 2, and by being secured to the partitions 5, 8. The return tube 1 empties through a tube 40, which is secured in the partition 5. Both the tubes 6 and 40 are fitted with flexible pipes, that of the former leading to a douche reservoir or to a tap connexion, and that of the latter to a receiving-reservoir. These flexible pipes may be compressed alternately by lugs 33, 34 on the rod 31 which is connected to a spring plug 29. When the lugs 33, 34 are in their mid-position, both tubes are open and a continuous lavage may take place. In order to hold the plug 29 in correct position to allow of this, a clip, as shown in Fig. 5, may be slipped under the flange 26, the plate 46 bearing against the top of the plug 29. The cone 9, which extends from the plate 8 to the partition 5 and acts as an obturator to the vaginal orifice, is completely closed in, and is rendered as nearly as possible vacuous, so that hot liquids may be passed through the inlet pipe without heat being conducted to the walls of the vaginal orifice. The nozzle 13 may have elongated openings instead of holes, as shown in Fig. 4.

Title: Monolithic memory
IPC: G11C11/411
Filed: 1973-05-07
Abstract: 1374058 Transistor data storage cells INTERNATIONAL BUSINESS MACHINES CORP 7 May 1973 [11 May 1972] 21624/73 Heading H3T [Also in Division G4] In a monolithic matrix type memory relatively low power is supplied to all cells during standby periods and relatively high power to a selected cell and only one adjacent cell during either read or write periods.  As described each cell (Fig. 1) comprises a pair of switching transistors T1, T2 forming a cross coupled bi-stable circuit, a pair of lead transistors D3, D4 and a pair of addressing transistors T5, T6. Each row of cells 11-14, 21-24 (Fig. 2) is connected to an associated row address line X1, X2 and each column address line Y1, Y2 is connected to a pair of columns 11, 21; 12, 22 and 13, 23; 14, 24. Each pair of bit lines, e.g. bit lines B02, B12 are common to the cells 12, 22, 13, 23 addressed by different address lines Y1, Y2. To read from for example cell 12, the potential of address line X1 is reduced and that of the address line Y1 raised so that cells 11, 12 are supplied with increased cell current. Current then flows through one of the transistors T5, T6 in cell 12 in dependence on which of the transistors T1, T2 is conductive, a differential amplifier connecting to bit lines B02, B12 detecting which transistor is conducting. To write information into for example cell 12 the potential of address line X1 is reduced and the potential of address line Y2 is raised. The potential of a selected one of bit lines B02, B12  is then raised so that one of the addressing transistors T5, T6 operates inversely to input current into the base of one of the transistors T1, T2 to render it conductive. The adjacent cell 13 is unaffected since the current in address line Y2 is high enough to prevent switching.

Abstract: 122,173. Petersen, C. Dec. 30, 1918. Drawings to Specification. Ammonia; nitrogen oxides.-These are obtained synthetically by electric treatment in an apparatus in which the current is produced by forcing the reacting gases to rotate in a magnetic field. Combustion gases, air, or steam may be used, or combustion may take place in the apparatus itself. For nitrogen oxides, the combustion gases may contain excess of air, or the oxygen may be obtained by decomposition of the carbonic acid or steam. The combustion air and fuel may be preheated by the gaseous products, and the air may be led around the apparatus. Most of the heat of combustion may be utilized for raising steam, burning tiles, and other purposes. Ammonia is obtained from a mixture of steam-and combustion gases.

Abstract: 1363049 Integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 14 May 1973 [28 June 1972] 22757/73 Heading H1K In a monolithic semi-conductor integrated circuit structure comprising a plurality of similar circuits connected to points distributed along the length of a conductive path by respective coupling elements the dimensions of the elements are varied from section to section of the path to maintain a substantially constant impedance between individual circuits and a given point on the path. As described the structure is a data store comprising an array of Schmidt trigger circuits constituted by IGFETs. Fig. 1 is a schematic of a column of the array while Fig. 2 shows the layout of one of the trigger circuits. Stored information is read by a pulse or word line 24 connected to the gates of IGFETs Q 5 , Q 6 . The area of the array is reduced by making the diffusions constituting bit lines 16, 18 narrow and hence of high resistance. The greater resistance a circuit move remote from the sense and drive circuits 20 would therefore see is compensated for by designing IGFETs Q 5 , Q 6  with different channel lengths so that their impedances are inversely related to their distances from these circuits. In the Fig. 2 design diffusions 28, 30, 32 and 34 together with the bit lines constitute the sources and drains of the various IGFETs while the gates are formed by parts of the conductive tracks 24, 36, 40, 42 overlying thinner portions of the oxide layer overlying the wafer, bounded by dotted lines and designated Q 1 -Q 6 .
