Abstract: 1,232,686. Rotary pumps and motors. RELIANCE ELECTRIC & ENG. CO. June 4, 1968, [July 21, 1967], No. 26476/68. Heading F1F. A rotary pump or motor comprises a housing 12, Fig. 5, comprising outer sections 14, 16, an intermediate section 18, a stationary port plate 22 between sections 14, 18 and a spacer plate 20 between sections 16, 18, and a centrally mounted shaft having an externally-tooth gerotor element 40 keyed thereon housing teeth 48, Fig. 7. The teeth 48 mesh with teeth 54, one more in number, of an orbiting gerotor element 40 also having external teeth 52 equal in number to the teeth 54 which mesh with internal teeth 36, one more in number, in the intermediate section 18. Ports 26, 28, Fig. 8 in the outer section 14 communicate respectively with annular grooves 74, 80 having radially outward and radially inward extensions 76, 82 communicating respective with alternate ports (72), (78), Fig. 6 (not shown) of a ring of ports through the port plate 22. On orbiting of the gerotor elements 50, half of peripheral slots 70 between the teeth 52 on the port plate side of the element are connected to the port 26 and the other half to the port 28. Either one of the ports 26, 28 may be an inlet port with the other one an outlet port. Operating as a motor, with the port 26 an inlet port, high pressure liquid is delivered to expanding volume chambers 60, between the teeth 36 of the section 18 and teeth 52 of the orbiting element to orbit the element 50 clockwise as viewed in Fig. 7. The liquid then being discharged from contracting volume chambers 62 to the port 28. As the element 50 orbits its inner teeth 54 engage the teeth 48 on the gerotor element 40 to rotate the shaft 30. The width and shape of the slots 70 may be varied in relation to the ports (72), (78) to obtain various operating characteristics, e. g., instead of the slots 70 holes may be drilled through the element. By modifying the porting system, spaces between the inner teeth 54 of the element 50 and the teeth 48 of the element 40 may also be used for pumping or augmenting the motor torque.

Abstract: 1,250,468. Casting machines. GEB. BUHLER A.G. 1 Nov., 1968 [8 Nov., 1967], No. 51833/68. Heading B3F. [Also in Division B5] In a die-casting machine having a mould cavity 13 connected to a gas suction device 50 via a shut-off valve 52 and having an injection monitoring element 60 positioned near the connection between the cavity and the suction device, control of the shut-off valve 52 is effected by an adjustable time switch 72 which is started in dependence on the commencement of injection. A time measuring device which may be constructed as part of the time switch, is provided for ascertaining the time interval from injection commencement and/or the closing the shut-off valve 52 to the response of the injection monitoring element 60, the value ascertained by the time measuring element being used for adjustment of the time switch. The time measuring element and the time switch may be constructed as one unit 72 or they may be separate units connected by a time delay element (93), Fig. 2 (not shown). Molten material is fed into the injection sleeve 9 through an aperture 10 and is then forced into the mould cavity 13 by a piston 19. At the commencement of injection the cam 15 on the piston-rod 14 moves away from the contact 76 which then closes and switches on the time switch 72. As soon as the piston 19 has closed the aperture 10, the cam follower of the vacuum control switch 69 runs off the cam 15, switches on the solenoid 63 and opens valve 53 thus allowing the mould cavity to be evacuated by the suction fan 50. When an arm in the time switch 72 reaches a pre-set control cam 721, the change over contact 74 is operated and thus causes the shut-off valve 52 to close. The time switch 72 continues to run as a time measuring device until molten material impinges on the injection monitoring element 60. The time interval between commencement of injection and the response of the injection monitoring element 60 is thus known and the position of the control cam 721 can be adjusted accordingly in preparation for subsequent injections. In an embodiment, the position of the control cam 721 is adjusted automatically between each operational cycle in dependence on the time interval measured by the time measuring element during the previous cycle. The actual time interval used for this adjustment is the time measured by the time measuring element minus the time delay associated with the time delay element (93). This time delay is so chosen as to be approximately equal to the time elapsing between excitation of the solenoid 62 and complete closure of the vacuum line 51 by the shut-off valve 52. The shortest time interval measured by the time measuring element during several previous cycles of the machine may be used as the basis for the adjustment.

Abstract: 1,257,408. Semi-conductor devices. SIEMENS A.G. 19 Aug., 1970 [20 Aug., 1969], No. 39864/70. Heading H1K. The interconnections of a monolithic integrated circuit are made by providing contacts, e.g. of platinum silicide in apertures in a passivating, e.g. nitride layer on the semiconductor wafer, then successively depositing overall layers of titanium, platinum, gold, optionally a further layer of platinum and finally a layer of readily etchable metal which back sputters more slowly than either gold or platinum, pattern etching the metal, back sputtering to remove the gold and platinum thus exposed and finally etching away the residual masking metal and the titanium exposed by back-sputtering. Suitable masking metals are hafnium, zirconium, vanadium, tungsten, chromium, tantalum, aluminium, molybdenum, and titanium, the last three being preferred. The difference between their back-sputtering rates and those of gold and platinum is increased by effecting the process in argon containing 5 vol per cent of oxygen or nitrogen. Best results are obtained by applying the layers in uninterrupted sequence in a multi-target H.F. cathode sputtered apparatus to specified thicknesses.

Abstract: 1,258,825. Sampling for chromatography. CESKOSLOVENSKA AKADEMIE VED. 8 April, 1969 [9 April, 1968], No. 17885/69. Heading B1X. An arrangement for introducing samples into liquid chromatography column 20 from either open sample containers 1 mounted on transportation table 2' or reservoir 27 comprises an eluent pump 4 which (with valves 8, 11 and 13 in the positions shown) passes eluent through lines 5, 10 , 12 and 14 to and through body 2 which is of the same general configuration as container 1, and thence by line 16 to column 20. The sample in container 1 is eluted therefrom to column 20 by bringing the container 1 to the position shown by body 2, and switching two-way valve 11 to its alternative (broken line) position, whereby eluent is pumped by lines 5, 21 and 22, and thence through container 1. In this way, a large number of samples in containers 1 mounted on table 2' may be automatically and successively introduced to the column. While this is proceeding, a further sample from reservoir 27 is drawn through valve 13 into sample loop 23 by means of pump 26. When the sample containers on table 2' require to be replenished, column 20 is flushed with eluent directly by switching valve 8 to its alternative (broken line) position. Then, with body 2 in place and valves 8 and 11 in the positions shown (unbroken lines), valve 13 is switched to its broken line position, whereby eluent from reservoir 4 is pumped by lines 5 and 12, through loop 23 and lines 14, 15 and 16 to column 20, thereby introducing the sample in loop 23. By providing such alternative sampling means, the arrangement may be operated without a break while containers 1 are replenished. In an alternative embodiment (see Fig. 2, not shown), the use of valves 8 and 11 is avoided by the use of a body 2 having two separate channels passing therethrough.

Abstract: 1295307 Digital calculators H J HUBINGER and D G HOFF 14 April 1970 [14 April 1969] 17801/70 Headings G4A and G4H A desk-top computer, which may be used for preparing estimates for bids for engineering contracts, receives certain of its input data from probes which are run over a drawing to provide signals indicative of the number of items, or of the length or the area of an item. The computer includes a visual display indicating the magnitude of the parameter determined. A first probe provides a pulse whenever it is pressed on to the drawing, enabling the computer to count the number of items. A second probe includes a wheel which is run along lines whose length is to be determined. Equi-spaced holes at its periphery are sensed by a lightsensitive unit, the number of pulses emitted being proportional to the length. Both these probes may include means (not described) for marking the drawing on contact. A third probe is a planimeter giving a number of pulses representing the area traced. In use, a key on the computer keyboard selects the required probe. A factor dependent on the scale of the drawing is keyed in. The factor may be fractional. The position of the decimal point relative to the display is also set up. The pulses from the probe are now added or subtracted, as selected by a key, to the content, if any, of an accumulator, the total being displayed. To store the count in the accumulator the address of the store is keyed in and displayed, the accumulator count passing to a register. When the store key is now operated the count in the register passes to the selected store. A count can be recalled from a store, and displayed by keying in the relevant address and pressing a Recall button. A count in the accumulator can be added to or subtracted from the count in a selected store. The counts in two stores can be added or subtracted, the result appearing in the accumulator and being displayed. Division and multiplication (e.g. item cost x number of items) are performed by recalling the count from the relevant store and keying in an appropriate factor. Volume may be calculated using a stored programme which determines the average of two areas and multiplies the result with the distance between them. The computer may be used for other calculations by direct entry of data via the keyboard. Further registers are provided for such calculations.
