Title: Improvements in and relating to priming and regulating devices for pumps of the screw, centrifugal and valveless type
IPC: F04D9/00
Filed: 1923-10-23
Abstract: 219,844. Seaborne, A. B. Oct. 23, 1923. Starting, facilitating; controlling.-A priming device for centrifugal and valveless pumps keeps water flowing through the pumps and only passes air in small controlled quantities. A tank a is connected above the pump c and between the pump inlet b and suction pipe d. Within the tank is an ejector device e of the type described in Specifications 202,595 and 206,878, and a float f controlling the valve g in the pipe h communicating between the reservoir i and the suction pipe d at the point where it enters the tank a. In normal operation all liquid passes through the tank a before entering the pump. If there is a break in the supply, the float f falls and opens the valve g. Liquid enters the tank a from the reservoir i and passes through the pump with entrained air from the suction pipe d until the break in supply is remedied and the float f rises to close the valve g. The reservoir i may have an independent supply or may be supplied from the pump discharge pipe k.

Title: Surface vehicle communication and location
Inventor: FULLER ROGER LYMAN
IPC: G08G1/127
Filed: 1970-06-02
Abstract: 1298032 Radar RAYTHEON CO 2 June 1970 [18 July 1969] 26637/70 Heading H4D Relates to communication with and location of mobile surface vehicles particularly in urban centers. According to the invention a control station (1, Fig. 1, not shown) communicates with a vehicle (S 1 ) via relay stations (R), a vehicle carries a transponder responsive to coded indicia from a relay station, the coded indicia includes a ranging tone, and each relay station affords a distance by measuring the phase difference between an originating and a reply ranging tone. In the embodiment the control station transmits messages to a selected relay station, each message comprising a synchronization part, a vehicle identification part and a coded data part. The selected relay station transmits each messages omnidirectionally and adds a ranging tone burst. The transponder on the identified vehicle synchronizes its decoding and encoding with the synchronization part and transmit an omnidirectional reply signal which includes a tone burst in phase with the originating tone burst. Each of n out of the m relay stations receives the original broadcast and when reply signals are received at the n relay stations the tone bursts are compared in phase and the phase determinations are transmitted back to the control station. If different ones of the n relay stations are used in turn as the selected relay station, an accurate fix of the vehicle is obtained. The relay stations may be disposed according to their powers.

Title: Apparatus for transferring a pattern of data signals
IPC: G06F5/01
Filed: 1963-07-09
Abstract: 1,042,464. Shifting arrangements for computers. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 9, 1963 [July 10, 1962], No. 27053/63. Heading G4A. Input data is shifted in parallel by selectively opening sets of gates to the passage of the data in response to a binary signal representing the amount of shift. Besides a simple shift, a ring (cyclic) shift is possible. There are three sets of gates: " logic levels " 1 to 3 (Fig. 1). At the first level a left or right shift or both in the case of a ring shift is possible, at the other levels only right shifts. Below each level is a set of or circuits to which the outputs of the gates are connected and which provide inputs to the next level of gates. At the first level the highest significant digits of the binary signal are acted upon, at lower levels the other digits. A left shift, if there are non- zero digits in the lower orders, is interpreted in the first level as greater than required and is corrected by appropriate right shifts in the lower levels. Thus a left shift of 53 is performed as a left shift of 64 in the first level, a right shift of 8 in the second level and a right shift of 3 in the third level. A ring shift causes simultaneous left and right shifts in the first level and compensating right shifts at lower levels. Thus, a left ring shift of 43 causes a left shift of 48 and a right shift of 16 at the first level (the input register has 64 locations) and right shifts of 0 and 3 at the respective lower levels. The result is that the bit originally in position 0 is now in position 43, and the bit originally in position 63 is now in position 42.

Title: Improvements in and relating to the deposition of refractory metals and alloys thereof
Inventor: CHARLTON MAURICE GEORGE
IPC: C23C16/06
Filed: 1954-09-27
Abstract: In a process for the deposition of tungsten, molybdenum or an alloy of these, the metal to be deposited is disposed in the vicinity of the article (e.g. of steel), to be coated and heated to a temperature above 1900 DEG C. (preferably 2200-3000 DEG C.) but below its melting point, the article itself being at between 500 DEG C. and 1400 DEG C., whilst the space between said metal and the article is filled with an atmosphere containing hydrogen and water vapour and/or oxygen.  This atmosphere may also contain one or more of nitrogen or the rare earth gases which latter can also if desired be arranged as a "blanket" around the article.  In an example, steel at 800 DEG C. is coated from a tungsten source heated to 2200 DEG C. the intervening atmosphere consisting of hydrogen at atmospheric pressure or slightly above, with water vapour sufficient to give saturation at 40-100 DEG C.  Tubes may be internally coated by making them then heated container, supporting a separately heated fixed or movable tungsten &c. filament down the middle of the tube and using either a static or flowing atmosphere.  The preferred method is to spray the article with gases produced by passing wet hydrogen over the hot tungsten &c. filament.  The gases presumably carrying a volatile tungsten &c. compound which decomposes on contact with the hot article. Certain metals e.g. chromium-rich steels which tend to oxidize in wet hydrogen may be given a preliminary coat by any conventional method (e.g. electrolysis), of a metal, such as nickel, inert to wet hydrogen.  Tubes may be made by depositing the tungsten &c. on a rod or tube of e.g. another metal and then removing the latter e.g. chemically.  Foil or sheet can be obtained by opening the resulting tube.
